  • Where do these mysterious DNS lookups come from and why are they slow?

    - by Hongli
    I have recently obtained a new dedicated server which I'm now setting up. It's running on 64-bit Debian 6.0. I have cloned a fairly large git repository (177 MB including working files) onto this server. Switching to a different branch is very very slow. On my laptop it takes 1-2 seconds, on this server it can take half a minute. After some investigation it turns out to be some kind of DNS timeout. Here's an exhibit from strace -s 128 git checkout release: stat("/etc/resolv.conf", {st_mode=S_IFREG|0644, st_size=132, ...}) = 0 socket(PF_INET, SOCK_DGRAM|SOCK_NONBLOCK, IPPROTO_IP) = 5 connect(5, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("213.133.99.99")}, 16) = 0 poll([{fd=5, events=POLLOUT}], 1, 0) = 1 ([{fd=5, revents=POLLOUT}]) sendto(5, "\235\333\1\0\0\1\0\0\0\0\0\0\35Debian-60-squeeze-64-minimal\n\17happyponies\3com\0\0\1\0\1", 67, MSG_NOSIGNAL, NULL, 0) = 67 poll([{fd=5, events=POLLIN}], 1, 5000) = 0 (Timeout) This snippet repeats several times per 'git checkout' call. My server's hostname was originally Debian-60-squeeze-64-minimal. I had changed it to shell.happyponies.com by running hostname shell.happyponies.com, editing /etc/hostname and rebooting the server. I don't understand the DNS protocol, but it looks like Git is trying to lookup the IP for Debian-60-squeeze-64-minimal as well as for happyponies.com. Why does Debian-60-squeeze-64-minimal come back even though I've already changed the host name? Why does Git perform DNS lookups at all? Why are these lookups so slow? I've already verified that all DNS servers in /etc/resolv.conf are up and responding slowly, yet Git's own lookups time out. Changing the host name back to Debian-60-squeeze-64-minimal seems to fix the slowness. Basically I just want to fix whatever DNS issues my server has because I'm sure they will cause more problems that just slowing down git checkout. But I'm not sure sure what the problem exactly is and what these symptoms mean.

  • IIS6 site using integrated authentication (NTLM) fails when accessed with Win7 / IE8

    - by Ciove
    Hi, I'm having pretty similar problems as described in case 139099, but the fix there doesn't seem to work for me. Here's the details: Server: Win2003Srv R2 SP2 (stadalone, not a member of a domain). IIS6, TCP/443 (https). Anonymous access disabled. Integrated Windows authentication enabled. Local useraccouts Each useraccount has own virtual folder with change access and read access to site root. The 'adsutil NTAuthenticationProviders "NTLM"' -thing set to site root and useraccount's virtual folder. Client: Win7 Enterprise Member of a AD-Domain IE8 Allows three login attepts then fails. Using [webservername][username] in the logon window (Windows security) Logon using other browsers (Chrome and Firefox) works OK. The Web services log shows one 401.2 and two 401.1 events. The Security Event log shows two events, first is Fauilure Audit (680), The second event is Fauilure Audit (529) with these details: Logon Failure: Reason: Unknown user name or bad password User Name: [username] Domain: [webservername] Logon Type: 3 Logon Process: NtLmSsp Authentication Package: NTLM Workstation Name: [MyWorkstation] Caller User Name: - Caller Domain: - Caller Logon ID: - Caller Process ID: - Transited Services: - Source Network Address: [999.999.999.999] Source Port: 20089 Any ideas appreciated.

  • How to find the source of a cryptic event viewer log

    - by mlsteeves
    I'm looking at the eventviewer logs, and I see a bunch Error entries in the Application log. (Windows Server 2008 R1). There is an error written to the logs about every 4 seconds. I need to find out which application is causing these events, is there anyway to find this out? Here is what each look like: Error 12/2/2010 12:00:09 PM Application 0 None The details for each error: Log Name: Application Source: Application Date: 12/2/2010 12:00:09 PM Event ID: 0 Task Category: None Level: Error Keywords: Classic User: N/A Computer: computer.domain Description: The description for Event ID 0 from source Application cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. If the event originated on another computer, the display information had to be saved with the event. The following information was included with the event: the message resource is present but the message is not found in the string/message table Event Xml: <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event"> <System> <Provider Name="Application" /> <EventID Qualifiers="0">0</EventID> <Level>2</Level> <Task>0</Task> <Keywords>0x80000000000000</Keywords> <TimeCreated SystemTime="2010-12-02T20:00:09.000Z" /> <EventRecordID>237167</EventRecordID> <Channel>Application</Channel> <Computer>computer.domain</Computer> <Security /> </System> <EventData> <Binary>534F434B...</Binary> </EventData> </Event>

  • Local user vs. domain user? What is the right way here?

    - by ebeeb
    I'm a software developer in a company with 6 employees. Everyone has a machine for him-/herself, so none of the machines is shared. I'm currently setting up my machine with Windows 8 and was experimenting a bit with domain and local user accounts. Correct me please if I'm wrong, but I think the idea behind is, that domain users generally should not be able to modify the configuration of a machine (like installing software), since they are able to login on every single machine in the domain. The local user (usually just one local administrator per machine) is the one who cares about the configuration of the machine. But in my case the login into the domain is just for being able to access directories/servers in the domain (I do not really know the details, all I know is, that loggin into the domain user account is necessary). So overall I've got a local admin account and a domain account used on my machine. While working I'm logged in to my domain user account. But it annoys me, that I always need to enter the credentials of my local user account when I'm about to update/install something, which happens quite often as a software developer. I fixed this with adding the domain account into the user accounts in my control panel and putting it into the Administrators group. The only thing I wanted to know about this: is there something REALLY bad about doing this? Or is there maybe a more common way to be able to act like a local admin, while logged in as a domain user? PS: I'm sorry about the tags, but I don't know the proper ones. I'd be glad if some of the superuser experts could fix this :-)

  • Active Directory FRS problems. 13508 error and other problems

    - by user59232
    I have 3 Domain Controllers. We will call them DC1, DC2 and DC3. DC3 and DC2 show Event ID 13508 in their FRS logs with no follow-up event(13509 I think) to say the error had been fixed. DC1's FRS log no matter what you do never shows any events besides FRS service stopped and started. DC1 holds the SYSVOL that needs to be replicated to the other DC's. The other DC's sysvol folders are empty. I have tried the burflag method of fixing this but I haven't had any luck. My procedure for that was to stop all FRS services on all DC's. Then set the burflag on DC1 to D4 and the other two DCs burflag to D2. Started FRS on DC1 and the only event's I see in DC1's FRS event logs are service stopped and service started messages. This fact is leading me to believe that something is wrong on FRS for DC1. I believe there should be events 13553 and 13516 in the FRS event logs after an authoritative sysvol restore. The other two DC's do not have anything in their SYSVOL, otherwise I would have made one of them the authoritative sysvol. DC1 is MS Server 2003 Enterprise Edition SP2 DC2 is MS Server 2003 Standard Edition SP1 DC3 is MS Server 2003 R2 Standard Edition SP2 I did not setup this domain originally but I am now the administrator of it, so I don't have a lot of background on why certain things may have been done in the past. My main goal is to try and fix these issues to get myself better prepared to decommision DC1 and add a DC running Server 2008 to my domain. Thanks.

  • Finding bluetooth link key in Win7, to double pair a device on dualboot computer

    - by Ilari Kajaste
    How can I dig up the bluetooth link key for a paired device in Win7? Is this something that is dependent on the bluetooth stack I'm using (Toshiba), or is there a generic place to store these in Win7? Note: I'm not talking about the six-digit code usually typed by the user during pairing - that is worthless since it's discarded after pairing process. What I mean is the 128-bit link key that the devices exchange during pairing, and use thereafter to encrypt all their bluetooth traffic. Background: I dualboot Win7 / Ubuntu on my laptop, and I would like to have my phone paired to both OS's. Since the dualbooting computer has only one bluetooth adapter and thus only one bluetooth address, I cannot do two pairings to the phone, since on the second pairing (windows) the phone just replaces the previous pairing (linux) to the same bluetooth address. A thread on Ubuntu forums pointed me to what I have to do - pair first on linux, then on windows, and then replace the link key on linux side with the one windows negotiated. I can find the linux side pairing key from /var/lib/bluetooth/[BD_ADDR]/linkkeys - no problems there. However, on windows side I can't find the key. According to the forum post, on windows side the key should be in SYSTEM\ControlSet002\services\BTHPORT\Parameters\Keys\[BD_ADDR] but while that registry key does exist, it has no subkeys. (And a similar registry path in ControlSet001 didn't have any subkeys either.) One thing I've been instructed to do is to capture all events during pairing with Sysinternals Process Monitor. I did this, but I haven't been able to find any useful information from the captured events, not even by exporting the data to a huge XML and grepping that with the BD_ADDRs (with or without colons). So how could I find the link key for a paired device in Win7? Some reference information: Wikipedia: Bluetooth, Security Now: Bluetooth security

  • Windows 7 PC freezes frequently with hard disk light constantly on

    - by Senthil
    I recently replaced a defective hard disk with a new one - Windows 7 - "A disk read error occured. Press Ctrl + Alt + Del to restart" I have been using the new hard disk with a Windows 7 installation for about 4 days. Now it has started freezing frequently. Sometimes every 2 minutes and sometimes every 10 seconds. There is lots of software installed - I am a developer and my PC is full of IDEs, database servers, web servers, developer tools, testing tools, all browsers etc.. My windows is up to date as of now. I have installed ALL updates including optional drivers etc. All my installed software is up to date. I scanned my computer using Microsoft Security Essentials and found nothing malicious. I did a chkdsk /r and found no problems. I did a memory diagnostic and found no problems. When I go into safe mode, it doesn't freeze and I am able to use it normally for longer periods of time. What other steps can I take to locate the problem?

  • Which default Database Systems come installed in Microsoft VS2010 Express?

    - by Tonygts
    Appreciate all advice 0n the following questions Which database systems (Ms SQL 2008, MS SQL Compact, or others) comes installed with VS2010 Express edition. SQL Server 2008 R2 Express is free, can we install and integrate with VS2010 Express? How to uninstall those database already come installed? I have installed VS2010 express on Windows 7; just VS2010 components (VB, C#, C++ and Web Developer) and without installing any other things like SQL Express. In the Console Panel-Program & Features' window, the installed list is shown below: Microsoft SQL Server 2008 Setup Support File Microsoft SQL Server 2008 Browser Microsoft SQL Server VSS Writer Microsoft SQL Server Database Publishing Wizard 1.4 Microsoft ASP.NET MVC2 - VWD Express 2010 Tools Microsoft SQL Server 2008 Management Objects Microsoft SQL Server Compact 3.5 SP2 ENU Microsoft SQL Server System CLR Types Microsoft Silverlight 3 SDK Microsoft ASP.NET MVC 2 Microsoft Visual Studio 2010 ADO.NET Entity Framework Tools Visual Studio 2010 Tools doe SQL Server Compact 3.5 SP2 ENU Web Deployment Tool Microsoft Visual Web Developer 2010 Express - ENU Microsoft Visual C++ 2010 Express - ENU Microsoft Visual C# 2010 Express - ENU Microsoft Visual Visual Basic 2010 Express - ENU Microsoft SQL Server 2008 As you can see, Microsoft SQL Server 2008 (last line) and near the top, Microsoft SQL Server Compact 3.5 SP2 ENU and many of their related SQL components such as Microsoft SQL Server 2008 R2 Management Objects are also installed. These are actually installed by installing VS2010 Express, but I have no idea how to use them or verify their valid existence from VS2010. Also, do I have to uninstall them before I install SQL Server 2008 R2, which is the latest version I believe? And what tool is needed to manage and create data source and tables?

  • Server 2008 R2 boot is at 2 hours and counting. What now?

    - by Jesse
    This morning, we rebooted our Server 2008 R2 box. No problem, came right back up. Then we shut it down and let it install windows updates. While it was off, we added some RAM. Then we turned it back on. The system came right back up to the "press ctrl-alt-delete" screen, so far, so good. I logged in. The system got as far as "Applying Group Policy" -- then spent almost an hour applying drive mappings. Finally finished that, and has now spent 30 minutes on waiting for the Event Notification Service. I still haven't been able to log in. Remote desktop service doesn't appear to be running yet. I tried viewing the event log from another machine. I see that the box is writing to the Security log, but there are no events in System or Application in the last 45 minutes. Digging through the System log of events from 45 minutes ago, I see a bunch of timeouts: A timeout (30000 milliseconds) was reached while waiting for a transaction response from the ShellHWDetection service. [lots of these] A timeout (30000 milliseconds) was reached while waiting for a transaction response from the wuauserv service. A timeout (30000 milliseconds) was reached while waiting for a transaction response from the SessionEnv service. A timeout (30000 milliseconds) was reached while waiting for a transaction response from the Schedule service. A timeout (30000 milliseconds) was reached while waiting for a transaction response from the CertPropSvc service. What can I do? Should I try shutting it down remotely, or will that do more damage?

  • The Web Hosting Connundrum for "not quite" developers

    - by saltcod
    Hey all, Apologies if this post feels like its been covered elsewhere, but I don't think it has. I've been down a winding web hosting road. To date, I've tried: Joyent, Media Temple, Bluehost, Hostgator, and finally Linode. The reason for switching are likely obvious to everyone: speed. With the exception of the lightening fast Linode, all of the shared hosts are absolutely sloooow. What do do when you're not really a "developer" While I'v grown addicted to the speed of Linode, I really don't feel like its where I should be. I have this nagging feeling in the back of my mind that one of these days (likely soon), I'm going to run into something that i won't be able to figure out and i'll have days worth of downtime. Just the other day, for example, I realized that one of my domains wasn't sending emails. After 4(!) hours looking into the problem, I still can't get sendmail or postfix to work. Four hours!! I want to be a Drupal expert, not a Ubuntu expert That's really the heart of my problem: I spend way too much time learning Ubuntu's ins-and-outs, and not nearly enough time working on Drupal. So here goes: Is there a web host out there anywhere that offers the speed of Linode, but will let me focus on Drupal instead of sys-admin-ing? Thanks! [ I know, I know. There are going to be lots of people who read this saying - "just learn Ubuntu like a real developer". And I get that. I do. But when I work full-time and try and develop some of these sites in my evenings and weekends, I'm really feeling like the sys-admin stuff gets in the way.

  • Office 2010 Trust Center settings: How to enable data connections in the "old" way?

    - by GSerg
    We're planning an upgrade Office 2003 - 2010 and have identified a big problem. In Office 2003, if the workbook you're opening contains a query table that fetches data from a data source automatically (upon file open or in certain intervals), then a security dialog pops up - whether you want to allow that. If you say Yes, the queries will refresh automatically when they need to. If you say No, the queries will not refresh automatically, neither on file open nor on time intervals, but you will be able to refresh any of them manually at any time by right-clicking and selecting Refresh. There is also a registry parameter to say, Don't display that dialog, just allow the queries. This is exactly what we want. On users' computers we have the registry parameter applied, so the users never see any dialogs. On developers' computers the parameter is not applied, so every time a file is opened the developer decides whether to allow the auto-refreshing for the current session. Usually the answer is No, because for developing, it is essential to not have quieres refresh when they want to, but instead, refresh them when the developer wants. The problem is that in Office 2010 which we are testing we can't find a way to achieve this functionality: The allow/disallow messages are now grouped into one yellow button, that either allows everything or disallows everything (including, say, macros, if macro security is set to "Disable, but ask"). If you don't click the yellow Allow button, the queries are disabled completely, not just for automatic execution. You cannot right-click and refresh a particular query -- doing that would summon a security dialog prompting for enabling queries, and if you say Yes, all queries in the document will be enabled for auto-execution and will start executing immediately. This sort of ruins our development environment. Is there a way to get the trust thingies in Office 2010 to work in the same way as before? Is there a yet another registry parameter to say, Prompt for auto-refresh, but allow manual refresh even when auto-refresh is disabled?

  • AMD processors witn graphics card bundled [closed]

    - by shybovycha
    Sorry for posting this question here - just don't know to which StackExchange website i should be writing. I've heard AMD created processors with video card bundled. So now these processors should work as fast as just usual processors with discrete video card but AMD's ones should use less power and spread less warm. Some googling around gave me the result like "AMD processors of A-series". They were mentioned to be build using that technology i described above. But on the other hand, we have a small rate of publishing and not-very-good quality of AMD drivers. I am a game-developer and web-developer so i need a powerful processor and graphics card and a lot of RAM on board (to make it possible to create a sample Grails application, for example or to create some 3D models in Maya/Cinema4D, for instance). Still i want my battery to be a long-living one, so power usage is a bit critical for me. So, my questions are: are there any processor building technology like i've described and which series they are (if they exist)? which processor shall fit the laptop the best: AMD one or i5/i7 on with nVidia graphics card for the purposes mentioned above?

  • Nested property binding

    - by EtherealMonkey
    Recently, I have been trying to wrap my mind around the BindingList<T> and INotifyPropertChanged. More specifically - How do I make a collection of objects (having objects as properties) which will allow me to subscribe to events throughout the tree? To that end, I have examined the code offered as examples by others. One such project that I downloaded was Nested Property Binding - CodeProject by "seesharper". Now, the article explains the implementation, but there was a question by "Someone@AnotherWorld" about "INotifyPropertyChanged in nested objects". His question was: Hi, nice stuff! But after a couple of time using your solution I realize the ObjectBindingSource ignores the PropertyChanged event of nested objects. E.g. I've got a class 'Foo' with two properties named 'Name' and 'Bar'. 'Name' is a string an 'Bar' reference an instance of class 'Bar', which has a 'Name' property of type string too and both classes implements INotifyPropertyChanged. With your binding source reading and writing with both properties ('Name' and 'Bar_Name') works fine but the PropertyChanged event works only for the 'Name' property, because the binding source listen only for events of 'Foo'. One workaround is to retrigger the PropertyChanged event in the appropriate class (here 'Foo'). What's very unclean! The other approach would be to extend ObjectBindingSource so that all owner of nested property which implements INotifyPropertyChanged get used for receive changes, but how? Thanks! I had asked about BindingList<T> yesterday and received a good answer from Aaronaught. In my question, I had a similar point as "Someone@AnotherWorld": if Keywords were to implement INotifyPropertyChanged, would changes be accessible to the BindingList through the ScannedImage object? To which Aaronaught's response was: No, they will not. BindingList only looks at the specific object in the list, it has no ability to scan all dependencies and monitor everything in the graph (nor would that always be a good idea, if it were possible). I understand Aaronaught's comment regarding this behavior not necessarily being a good idea. Additionally, his suggestion to have my bound object "relay" events on behalf of it's member objects works fine and is perfectly acceptable. For me, "re-triggering" the PropertyChanged event does not seem so unclean as "Someone@AnotherWorld" laments. I do understand why he protests - in the interest of loosely coupled objects. However, I believe that coupling between objects that are part of a composition is logical and not so undesirable as this may be in other scenarios. (I am a newb, so I could be waaayyy off base.) Anyway, in the interest of exploring an answer to the question by "Someone@AnotherWorld", I altered the MainForm.cs file of the example project from Nested Property Binding - CodeProject by "seesharper" to the following: using System; using System.Collections.Generic; using System.ComponentModel; using System.Core.ComponentModel; using System.Windows.Forms; namespace ObjectBindingSourceDemo { public partial class MainForm : Form { private readonly List<Customer> _customers = new List<Customer>(); private readonly List<Product> _products = new List<Product>(); private List<Order> orders; public MainForm() { InitializeComponent(); dataGridView1.AutoGenerateColumns = false; dataGridView2.AutoGenerateColumns = false; CreateData(); } private void CreateData() { _customers.Add( new Customer(1, "Jane Wilson", new Address("98104", "6657 Sand Pointe Lane", "Seattle", "USA"))); _customers.Add( new Customer(1, "Bill Smith", new Address("94109", "5725 Glaze Drive", "San Francisco", "USA"))); _customers.Add( new Customer(1, "Samantha Brown", null)); _products.Add(new Product(1, "Keyboard", 49.99)); _products.Add(new Product(2, "Mouse", 10.99)); _products.Add(new Product(3, "PC", 599.99)); _products.Add(new Product(4, "Monitor", 299.99)); _products.Add(new Product(5, "LapTop", 799.99)); _products.Add(new Product(6, "Harddisc", 89.99)); customerBindingSource.DataSource = _customers; productBindingSource.DataSource = _products; orders = new List<Order>(); orders.Add(new Order(1, DateTime.Now, _customers[0])); orders.Add(new Order(2, DateTime.Now, _customers[1])); orders.Add(new Order(3, DateTime.Now, _customers[2])); #region Added by me OrderLine orderLine1 = new OrderLine(_products[0], 1); OrderLine orderLine2 = new OrderLine(_products[1], 3); orderLine1.PropertyChanged += new PropertyChangedEventHandler(OrderLineChanged); orderLine2.PropertyChanged += new PropertyChangedEventHandler(OrderLineChanged); orders[0].OrderLines.Add(orderLine1); orders[0].OrderLines.Add(orderLine2); #endregion // Removed by me in lieu of region above. //orders[0].OrderLines.Add(new OrderLine(_products[0], 1)); //orders[0].OrderLines.Add(new OrderLine(_products[1], 3)); ordersBindingSource.DataSource = orders; } #region Added by me // Have to wait until the form is Shown to wire up the events // for orderDetailsBindingSource. Otherwise, they are triggered // during MainForm().InitializeComponent(). private void MainForm_Shown(object sender, EventArgs e) { orderDetailsBindingSource.AddingNew += new AddingNewEventHandler(orderDetailsBindSrc_AddingNew); orderDetailsBindingSource.CurrentItemChanged += new EventHandler(orderDetailsBindSrc_CurrentItemChanged); orderDetailsBindingSource.ListChanged += new ListChangedEventHandler(orderDetailsBindSrc_ListChanged); } private void orderDetailsBindSrc_AddingNew( object sender, AddingNewEventArgs e) { } private void orderDetailsBindSrc_CurrentItemChanged( object sender, EventArgs e) { } private void orderDetailsBindSrc_ListChanged( object sender, ListChangedEventArgs e) { ObjectBindingSource bindingSource = (ObjectBindingSource)sender; if (!(bindingSource.Current == null)) { // Unsure if GetType().ToString() is required b/c ToString() // *seems* // to return the same value. if (bindingSource.Current.GetType().ToString() == "ObjectBindingSourceDemo.OrderLine") { if (e.ListChangedType == ListChangedType.ItemAdded) { // I wish that I knew of a way to determine // if the 'PropertyChanged' delegate assignment is null. // I don't like the current test, but it seems to work. if (orders[ ordersBindingSource.Position].OrderLines[ e.NewIndex].Product == null) { orders[ ordersBindingSource.Position].OrderLines[ e.NewIndex].PropertyChanged += new PropertyChangedEventHandler( OrderLineChanged); } } if (e.ListChangedType == ListChangedType.ItemDeleted) { // Will throw exception when leaving // an OrderLine row with unitialized properties. // // I presume this is because the item // has already been 'disposed' of at this point. // *but* // Will it be actually be released from memory // if the delegate assignment for PropertyChanged // was never removed??? if (orders[ ordersBindingSource.Position].OrderLines[ e.NewIndex].Product != null) { orders[ ordersBindingSource.Position].OrderLines[ e.NewIndex].PropertyChanged -= new PropertyChangedEventHandler( OrderLineChanged); } } } } } private void OrderLineChanged(object sender, PropertyChangedEventArgs e) { MessageBox.Show(e.PropertyName, "Property Changed:"); } #endregion } } In the method private void orderDetailsBindSrc_ListChanged(object sender, ListChangedEventArgs e) I am able to hook up the PropertyChangedEventHandler to the OrderLine object as it is being created. However, I cannot seem to find a way to unhook the PropertyChangedEventHandler from the OrderLine object before it is being removed from the orders[i].OrderLines list. So, my questions are: Am I simply trying to do something that is very, very wrong here? Will the OrderLines object that I add the delegate assignments to ever be released from memory if the assignment is not removed? Is there a "sane" method of achieving this scenario? Also, note that this question is not specifically related to my prior. I have actually solved the issue which had prompted me to inquire before. However, I have reached a point with this particular topic of discovery where my curiosity has exceeded my patience - hopefully someone here can shed some light on this?

  • YouTube API Security Error Flex

  • How to find an entry-level job after you already have a graduate degree?

    - by Uri
    Note: I asked this question in early 2009. A couple of months later, I found a great job. I've previously updated this question with some tips for whoever ends up in a similar situation, and now cleaned it up a little for the benefit of the fresh batch of graduates. Original post: In my early 20s I abandoned a great C++ development career path in a major company to go to graduate school and get a research masters (3 years). I did another year in industrial research, and then moved to the US to attend graduate school again, getting another masters and a Ph.D in software engineering from a top school (another 6 years down the drain). I was coding the whole way throughout my degrees (core Java and Eclipse plug-ins) and working on research related to software engineering (usability of APIs). I ended up graduating the year of the recession, with a son on the way and the prospects of no healthcare. Academic jobs and industrial research jobs are quite scarce. Initially, I was naive, thinking that with my background, I could easily find a coding job. Big mistake. It turns out that I'm in a complicated position. Entry level positions are usually offered to college undergraduates. I attended my school's career fairs, but you could immediately see signs of Ph.D. aversion and overqualification issues. Some of the recruiters I spoke with explicitly told me that they wanted 20 year olds with clean slates, and some were looking for interns since they are in various forms of hiring freezes. I managed to get a couple of interviews from these career fairs and through recruiters. However, since I've been out of school for a long time and programming primarily in Java, I am also no longer proficient in C/C++ and the usual range of college-level interview questions that everyone uses. I had no problems with this when I was 19 and interviewing for my first job since a lot of what you do in C is manipulate pointers and I was coding C++ for fun and for school. Later I was routinely doing pointer manipulation on the job, and during my first masters taught college courses with data structures and C++. But even though I remember many properties of C++ well, it's been close to ten years since I regularly used C++ and pointers. As a Java developer I rarely had to work at this level, but experience in OOD and in writing good maintainable code is meaningless for C++ interviews. Reading books as a refresh and looking at sample code did not do the trick. I also looked at mid-to-senior level Java positions, but most of them focused on J2EE APIs rather than on core Java and required a certain number of years in industrial positions. Coding research tools and prior C++ experience doesn't count. So that sends me back to entry-level jobs that are posted through job-boards, and these are not common (mostly they are Monster junk), and small companies are even less likely to answer a Ph.D. compared to the giants who participate in top-10 career fairs. Even worse, in many companies initial screening is done by HR folks who really don't want to deal with anything anomalous like a Ph.D. Any tips on how I should approach this intractable position? For example, what should I write in cover letters? Note that while immigration is not an issue for me, I cannot go freelance as I need the benefits (and in particular group health insurance). During my studies I had no time to contribute to open-source projects or maintain a popular blog, so even if I invested in that now there would be no immediate benefit. Updates: In the two months after posting this I received several offers to work as a core Java developer in the financial industry and accepted one from a firm where I am working to this day. For those who find themselves in similar situations, here are my tips: Give up on trying to find an entry level positions. You can't undo time. Accept the fact that there is Ph.D. discrimination in the job market (some might say rightfully so). It is legal to discriminate based on education. No point fighting it. The most important tip is to focus on the language you are comfortable with. The sad truth about programming in a particular language is that it is not like riding a bike. If you haven't used a language in the last few years, and can't actually apply it routinely (not just as a refresher) before you start your search, it is going to be very difficult to do well in an interview. Now that I'm interviewing others, I routinely see it in folks with a mixed C++/Java background. We maintain "a shadow" of the old language but end up with a weird mix that makes it hard to interview on either. Entry-level folks are at an advantage here since they usually have one language. Memory can help you do great in a screening interview, but without recent day-to-day experience, code tests will be difficult. Despite the supposed relation, core Java programming and J2EE programming are two different things with different skillsets. If you come from academia, you likely have very little J2EE experience and may find it hard to get accepted for a J2EE job. J2EE jobs seem to have a larger list of acronyms in their requirements. In addition, from interviewing J2EE developers it seems that for many there is a focus on mastering specific APIs and architectures, whereas core Java development tends to be secondary. In the same way that I can no longer manipulate pointers well, a J2EE developer may have difficulties doing low level Java manipulation. This puts you at a relative advantage in competing for core Java jobs! If you are able to work for startups (in terms of family life and stability) or migrate to startup-rich areas such as the west coast, you can find many exciting opportunities where advanced degrees are a benefit. I've since been approached by several startups, although I had to decline. Work through a recruiter if possible. They have direct contacts with the hiring parties, allowing you to "stand out". It is better to get a clear yes/no confirmation from a recruiter on whether a company might be interested in interviewing you, than it is to send your resume and hope that someone will ever see it. Recruiters are also a great way of bypassing HR. However, also beware of recruiters. They have a vested interest and will go to various shady practices and pressure tactics. To find a good recruiter, talk to a friend who declined a job offer he got through a recruiter. A good recruiter, to me, is measured in how they handle that. Interview for the jobs that require your core strength. If you're rusty or entirely unfamiliar with a technology around which the job revolves, you're probably not a good match. Yes, you probably have the talent to master them, but most companies would want "instant gratification". I got my offers from companies that wanted core Java developer. I didn't do well on places that wanted advance C++ because I am too rusty and not up to date on recent libraries. I also didn't hear from companies that wanted lots of J2EE experience, and that's ok. Finding companies that want core Java without web is harder, but exists in specific industries (e.g., finance, defense). This requires a lot more legwork in terms of search, but these jobs do exist. There are different interview styles. Some companies focus on puzzles, some companies focus on algorithms, and some companies focus on design and coding skills. I had the most success in places where the questions were the most related to the function I would have been performing. Pick companies accordingly as well.

  • Backbone.js Adding Model to Collection Issue

    - by jtmgdevelopment
    I am building a test application in Backbone.js (my first app using Backbone). The app goes like this: Load Data from server "Plans" Build list of plans and show to screen There is a button to add a new plan Once new plan is added, add to collection ( do not save to server as of now ) redirect to index page and show the new collection ( includes the plan you just added) My issue is with item 5. When I save a plan, I add the model to the collection then redirect to the initial view. At this point, I fetch data from the server. When I fetch data from the server, this overwrites my collection and my added model is gone. How can I prevent this from happening? I have found a way to do this but it is definitely not the correct way at all. Below you will find my code examples for this. Thanks for the help. PlansListView View: var PlansListView = Backbone.View.extend({ tagName : 'ul', initialize : function() { _.bindAll( this, 'render', 'close' ); //reset the view if the collection is reset this.collection.bind( 'reset', this.render , this ); }, render : function() { _.each( this.collection.models, function( plan ){ $( this.el ).append( new PlansListItemView({ model: plan }).render().el ); }, this ); return this; }, close : function() { $( this.el ).unbind(); $( this.el ).remove(); } });//end NewPlanView Save Method var NewPlanView = Backbone.View.extend({ tagName : 'section', template : _.template( $( '#plan-form-template' ).html() ), events : { 'click button.save' : 'savePlan', 'click button.cancel' : 'cancel' }, intialize: function() { _.bindAll( this, 'render', 'save', 'cancel' ); }, render : function() { $( '#container' ).append( $( this.el ).html(this.template( this.model.toJSON() )) ); return this; }, savePlan : function( event ) { this.model.set({ name : 'bad plan', date : 'friday', desc : 'blah', id : Math.floor(Math.random()*11), total_stops : '2' }); this.collection.add( this.model ); app.navigate('', true ); event.preventDefault(); }, cancel : function(){} }); Router (default method): index : function() { this.container.empty(); var self = this; //This is a hack to get this to work //on default page load fetch all plans from the server //if the page has loaded ( this.plans is defined) set the updated plans collection to the view //There has to be a better way!!

  • SQLAuthority News – TechEd India – April 12-14, 2010 Bangalore – An Unforgettable Experience – An Op

    - by pinaldave
    TechEd India was one of the largest Technology events in India led by Microsoft. This event was attended by more than 3,000 technology enthusiasts, making it one of the most well-organized events of the year. Though I attempted to attend almost all the technology events here, I have not seen any bigger or better event in Indian subcontinents other than this. There are 21 Technical Tracks at Tech·Ed India 2010 that span more than 745 learning opportunities. I was fortunate enough to be a part of this whole event as a speaker and a delegate, as well. TechEd India Speaker Badge and A Token of Lifetime Hotel Selection I presented three different sessions at TechEd India and was also a part of panel discussion. (The details of the sessions are given at the end of this blog post.) Due to extensive traveling, I stay away from my family occasionally. For this reason, I took my wife – Nupur and daughter Shaivi (8 months old) to the event along with me. We stayed at the same hotel where the event was organized so as to maximize my time bonding with my family and to have more time in networking with technology community, at the same time. The hotel Lalit Ashok is the largest and most luxurious venue one can find in Bangalore, located in the middle of the city. The cost of the hotel was a bit pricey, but looking at all the advantages, I had decided to ask for a booking there. Hotel Lalit Ashok Nupur Dave and Shaivi Dave Arrival Day – DAY 0 – April 11, 2010 I reached the event a day earlier, and that was one wise decision for I was able to relax a bit and go over my presentation for the next day’s course. I am a kind of person who likes to get everything ready ahead of time. I was also able to enjoy a pleasant evening with several Microsoft employees and my family friends. I even checked out the location where I would be doing presentations the next day. I was fortunate enough to meet Bijoy Singhal from Microsoft who helped me out with a few of the logistics issues that occured the day before. I was not aware of the fact that the very next day he was going to be “The Man” of the TechEd 2010 event. Vinod Kumar from Microsoft was really very kind as he talked to me regarding my subsequent session. He gave me some suggestions which were really helpful that I was able to incorporate them during my presentation. Finally, I was able to meet Abhishek Kant from Microsoft; his valuable suggestions and unlimited passion have inspired many people like me to work with the Community. Pradipta from Microsoft was also around, being extremely busy with logistics; however, in those busy times, he did find some good spare time to have a chat with me and the other Community leaders. I also met Harish Ranganathan and Sachin Rathi, both from Microsoft. It was so interesting to listen to both of them talking about SharePoint. I just have no words to express my overwhelmed spirit because of all these passionate young guys - Pradipta,Vinod, Bijoy, Harish, Sachin and Ahishek (of course!). Map of TechEd India 2010 Event Day 1 – April 12, 2010 From morning until night time, today was truly a very busy day for me. I had two presentations and one panel discussion for the day. Needless to say, I had a few meetings to attend as well. The day started with a keynote from S. Somaseger where he announced the launch of Visual Studio 2010. The keynote area was really eye-catching because of the very large, bigger-than- life uniform screen. This was truly one to show. The title music of the keynote was very interesting and it featured Bijoy Singhal as the model. It was interesting to talk to him afterwards, when we laughed at jokes together about his modeling assignment. TechEd India Keynote Opening Featuring Bijoy TechEd India 2010 Keynote – S. Somasegar Time: 11:15pm – 11:45pm Session 1: True Lies of SQL Server – SQL Myth Buster Following the excellent keynote, I had my very first session on the subject of SQL Server Myth Buster. At first, I was a bit nervous as right after the keynote, for this was my very first session and during my presentation I saw lots of Microsoft Product Team members. Well, it really went well and I had a really good discussion with attendees of the session. I felt that a well begin was half-done and my confidence was regained. Right after the session, I met a few of my Community friends and had meaningful discussions with them on many subjects. The abstract of the session is as follows: In this 30-minute demo session, I am going to briefly demonstrate few SQL Server Myths and their resolutions as I back them up with some demo. This demo presentation is a must-attend for all developers and administrators who would come to the event. This is going to be a very quick yet fun session. Pinal Presenting session at TechEd India 2010 Time: 1:00 PM – 2:00 PM Lunch with Somasegar After the session I went to see my daughter, and then I headed right away to the lunch with S. Somasegar – the keynote speaker and senior vice president of the Developer Division at Microsoft. I really thank to Abhishek who made it possible for us. Because of his efforts, all the MVPs had the opportunity to meet such a legendary person and had to talk with them on Microsoft Technology. Though Somasegar is currently holding such a high position in Microsoft, he is very polite and a real gentleman, and how I wish that everybody in industry is like him. Believe me, if you spread love and kindness, then that is what you will receive back. As soon as lunch time was over, I ran to the session hall as my second presentation was about to start. Time: 2:30pm – 3:30pm Session 2: Master Data Services in Microsoft SQL Server 2008 R2 Business Intelligence is a subject which was widely talked about at TechEd. Everybody was interested in this subject, and I did not excuse myself from this great concept as well. I consider myself fortunate as I was presenting on the subject of Master Data Services at TechEd. When I had initially learned this subject, I had a bit of confusion about the usage of this tool. Later on, I decided that I would tackle about how we all developers and DBAs are not able to understand something so simple such as this, and even worst, creating confusion about the technology. During system designing, it is very important to have a reference material or master lookup tables. Well, I talked about the same subject and presented the session keeping that as my center talk. The session went very well and I received lots of interesting questions. I got many compliments for talking about this subject on the real-life scenario. I really thank Rushabh Mehta (CEO, Solid Quality Mentors India) for his supportive suggestions that helped me prepare the slide deck, as well as the subject. Pinal Presenting session at TechEd India 2010 The abstract of the session is as follows: SQL Server Master Data Services will ship with SQL Server 2008 R2 and will improve Microsoft’s platform appeal. This session provides an in-depth demonstration of MDS features and highlights important usage scenarios. Master Data Services enables consistent decision-making process by allowing you to create, manage and propagate changes from a single master view of your business entities. Also, MDS – Master Data-hub which is a vital component, helps ensure the consistency of reporting across systems and deliver faster and more accurate results across the enterprise. We will talk about establishing the basis for a centralized approach to defining, deploying, and managing master data in the enterprise. Pinal Presenting session at TechEd India 2010 The day was still not over for me. I had ran into several friends but we were not able keep our enthusiasm under control about all the rumors saying that SQL Server 2008 R2 was about to be launched tomorrow in the keynote. I then ran to my third and final technical event for the day- a panel discussion with the top technologies of India. Time: 5:00pm – 6:00pm Panel Discussion: Harness the power of Web – SEO and Technical Blogging As I have delivered two technical sessions by this time, I was a bit tired but  not less enthusiastic when I had to talk about Blog and Technology. We discussed many different topics there. I told them that the most important aspect for any blog is its content. We discussed in depth the issues with plagiarism and how to avoid it. Another topic of discussion was how we technology bloggers can create awareness in the Community about what the right kind of blogging is and what morally and technically wrong acts are. A couple of questions were raised about what type of liberty a person can have in terms of writing blogs. Well, it was generically agreed that a blog is mainly a representation of our ideas and thoughts; it should not be governed by external entities. As long as one is writing what they really want to say, but not providing incorrect information or not practicing plagiarism, a blogger should be allowed to express himself. This panel discussion was supposed to be over in an hour, but the interest of the participants was remarkable and so it was extended for 30 minutes more. Finally, we decided to bring to a close the discussion and agreed that we will continue the topic next year. TechEd India Panel Discussion on Web, Technology and SEO Surprisingly, the day was just beginning after doing all of these. By this time, I have almost met all the MVP who arrived at the event, as well as many Microsoft employees. There were lots of Community folks present, too. I decided that I would go to meet several friends from the Community and continue to communicate with me on SQLAuthority.com. I also met Abhishek Baxi and had a good talk with him regarding Win Mobile and Twitter. He also took a very quick video of me wherein I spoke in my mother’s tongue, Gujarati. It was funny that I talked in Gujarati almost all the day, but when I was talking in the interview I could not find the right Gujarati words to speak. I think we all think in English when we think about Technology, so as to address universality. After meeting them, I headed towards the Speakers’ Dinner. Time: 8:00 PM – onwards Speakers Dinner The Speakers’ dinner was indeed a wonderful opportunity for all the speakers to get together and relax. We talked so many different things, from XBOX to Hindi Movies, and from SQL to Samosas. I just could not express how much fun I had. After a long evening, when I returned tmy room and met Shaivi, I just felt instantly relaxed. Kids are really gifts from God. Today was a really long but exciting day. So many things happened in just one day: Visual Studio Lanch, lunch with Somasegar, 2 technical sessions, 1 panel discussion, community leaders meeting, speakers dinner and, last but not leas,t playing with my child! A perfect day! Day 2 – April 13, 2010 Today started with a bang with the excellent keynote by Kamal Hathi who launched SQL Server 2008 R2 in India and demonstrated the power of PowerPivot to all of us. 101 Million Rows in Excel brought lots of applause from the audience. Kamal Hathi Presenting Keynote at TechEd India 2010 The day was a bit easier one for me. I had no sessions today and no events planned. I had a few meetings planned for the second day of the event. I sat in the speaker’s lounge for half a day and met many people there. I attended nearly 9 different meetings today. The subjects of the meetings were very different. Here is a list of the topics of the Community-related meetings: SQL PASS and its involvement in India and subcontinents How to start community blogging Forums and developing aptitude towards technology Ahmedabad/Gandhinagar User Groups and their developments SharePoint and SQL Business Meeting – a client meeting Business Meeting – a potential performance tuning project Business Meeting – Solid Quality Mentors (SolidQ) And family friends Pinal Dave at TechEd India The day passed by so quickly during this meeting. In the evening, I headed to Partners Expo with friends and checked out few of the booths. I really wanted to talk about some of the products, but due to the freebies there was so much crowd that I finally decided to just take the contact details of the partner. I will now start sending them with my queries and, hopefully, I will have my questions answered. Nupur and Shaivi had also one meeting to attend; it was with our family friend Vijay Raj. Vijay is also a person who loves Technology and loves it more than anybody. I see him growing and learning every day, but still remaining as a ‘human’. I believe that if someone acquires as much knowledge as him, that person will become either a computer or cyborg. Here, Vijay is still a kind gentleman and is able to stay as our close family friend. Shaivi was really happy to play with Uncle Vijay. Pinal Dave and Vijay Raj Renuka Prasad, a Microsoft MVP, impressed me with his passion and knowledge of SQL. Every time he gives me credit for his success, I believe that he is very humble. He has way more certifications than me and has worked many more years with SQL compared to me. He is an excellent photographer as well. Most of the photos in this blog post have been taken by him. I told him if ever he wants to do a part time job, he can do the photography very well. Pinal Dave and Renuka Prasad I also met L Srividya from Microsoft, whom I was looking forward to meet. She is a bundle of knowledge that everyone would surely learn a lot from her. I was able to get a few minutes from her and well, I felt confident. She enlightened me with SQL Server BI concepts, domain management and SQL Server security and few other interesting details. I also had a wonderful time talking about SharePoint with fellow Solid Quality Mentor Joy Rathnayake. He is very passionate about SharePoint but when you talk .NET and SQL with him, he is still overwhelmingly knowledgeable. In fact, while talking to him, I figured out that the recent training he delivered was on SQL Server 2008 R2. I told him a joke that it hurts my ego as he is more popular now in SQL training and consulting than me. I am sure all of you agree that working with good people is a gift from God. I am fortunate enough to work with the best of the best Industry experts. It was a great pleasure to hang out with my Community friends – Ahswin Kini, HimaBindu Vejella, Vasudev G, Suprotim Agrawal, Dhananjay, Vikram Pendse, Mahesh Dhola, Mahesh Mitkari,  Manu Zacharia, Shobhan, Hardik Shah, Ashish Mohta, Manan, Subodh Sohani and Sanjay Shetty (of course!) .  (Please let me know if I have met you at the event and forgot your name to list here). Time: 8:00 PM – onwards Community Leaders Dinner After lots of meetings, I headed towards the Community Leaders dinner meeting and met almost all the folks I met in morning. The discussion was almost the same but the real good thing was that we were enjoying it. The food was really good. Nupur was invited in the event, but Shaivi could not come. When Nupur tried to enter the event, she was stopped as Shaivi did not have the pass to enter the dinner. Nupur expressed that Shaivi is only 8 months old and does not eat outside food as well and could not stay by herself at this age, but the door keeper did not agree and asked that without the entry details Shaivi could not go in, but Nupur could. Nupur called me on phone and asked me to help her out. By the time, I was outside; the organizer of the event reached to the door and happily approved Shaivi to join the party. Once in the party, Shaivi had lots of fun meeting so many people. Shaivi Dave and Abhishek Kant Dean Guida (Infragistics President and CEO) and Pinal Dave (SQLAuthority.com) Day 3 – April 14, 2010 Though, it was last day, I was very much excited today as I was about to present my very favorite session. Query Optimization and Performance Tuning is my domain expertise and I make my leaving by consulting and training the same. Today’s session was on the same subject and as an additional twist, another subject about Spatial Database was presented. I was always intrigued with Spatial Database and I have enjoyed learning about it; however, I have never thought about Spatial Indexing before it was decided that I will do this session. I really thank Solid Quality Mentor Dr. Greg Low for his assistance in helping me prepare the slide deck and also review the content. Furthermore, today was really what I call my ‘learning day’ . So far I had not attended any session in TechEd and I felt a bit down for that. Everybody spends their valuable time & money to learn something new and exciting in TechEd and I had not attended a single session at the moment thinking that it was already last day of the event. I did have a plan for the day and I attended two technical sessions before my session of spatial database. I attended 2 sessions of Vinod Kumar. Vinod is a natural storyteller and there was no doubt that his sessions would be jam-packed. People attended his sessions simply because Vinod is syhe speaker. He did not have a single time disappointed audience; he is truly a good speaker. He knows his stuff very well. I personally do not think that in India he can be compared to anyone for SQL. Time: 12:30pm-1:30pm SQL Server Query Optimization, Execution and Debugging Query Performance I really had a fun time attending this session. Vinod made this session very interactive. The entire audience really got into the presentation and started participating in the event. Vinod was presenting a small problem with Query Tuning, which any developer would have encountered and solved with their help in such a fashion that a developer feels he or she have already resolved it. In one question, I was the only one who was ready to answer and Vinod told me in a light tone that I am now allowed to answer it! The audience really found it very amusing. There was a huge crowd around Vinod after the session. Vinod – A master storyteller! Time: 3:45pm-4:45pm Data Recovery / consistency with CheckDB This session was much heavier than the earlier one, and I must say this is my most favorite session I EVER attended in India. In this TechEd I have only attended two sessions, but in my career, I have attended numerous technical sessions not only in India, but all over the world. This session had taken my breath away. One by one, Vinod took the different databases, and started to corrupt them in different ways. Each database has some unique ways to get corrupted. Once that was done, Vinod started to show the DBCC CEHCKDB and demonstrated how it can solve your problem. He finally fixed all the databases with this single tool. I do have a good knowledge of this subject, but let me honestly admit that I have learned a lot from this session. I enjoyed and cheered during this session along with other attendees. I had total satisfaction that, just like everyone, I took advantage of the event and learned something. I am now TECHnically EDucated. Pinal Dave and Vinod Kumar After two very interactive and informative SQL Sessions from Vinod Kumar, the next turn me presenting on Spatial Database and Indexing. I got once again nervous but Vinod told me to stay natural and do my presentation. Well, once I got a huge stage with a total of four projectors and a large crowd, I felt better. Time: 5:00pm-6:00pm Session 3: Developing with SQL Server Spatial and Deep Dive into Spatial Indexing Pinal Presenting session at TechEd India 2010 Pinal Presenting session at TechEd India 2010 I kicked off this session with Michael J Swart‘s beautiful spatial image. This session was the last one for the day but, to my surprise, I had more than 200+ attendees. Slowly, the rain was starting outside and I was worried that the hall would not be full; despite this, there was not a single seat available in the first five minutes of the session. Thanks to all of you for attending my presentation. I had demonstrated the map of world (and India) and quickly explained what  Geographic and Geometry data types in Spatial Database are. This session had interesting story of Indexing and Comparison, as well as how different traditional indexes are from spatial indexing. Pinal Presenting session at TechEd India 2010 Due to the heavy rain during this event, the power went off for about 22 minutes (just an accident – nobodies fault). During these minutes, there were no audio, no video and no light. I continued to address the mass of 200+ people without any audio device and PowerPoint. I must thank the audience because not a single person left from the session. They all stayed in their place, some moved closure to listen to me properly. I noticed that the curiosity and eagerness to learn new things was at the peak even though it was the very last session of the TechEd. Everybody wanted get the maximum knowledge out of this whole event. I was touched by the support from audience. They listened and participated in my session even without any kinds of technology (no ppt, no mike, no AC, nothing). During these 22 minutes, I had completed my theory verbally. Pinal Presenting session at TechEd India 2010 After a while, we got the projector back online and we continued with some exciting demos. Many thanks to Microsoft people who worked energetically in background to get the backup power for project up. I had a very interesting demo wherein I overlaid Bangalore and Hyderabad on the India Map and find their aerial distance between them. After finding the aerial distance, we browsed online and found that SQL Server estimates the exact aerial distance between these two cities, as compared to the factual distance. There was a huge applause from the crowd on the subject that SQL Server takes into the count of the curvature of the earth and finds the precise distances based on details. During the process of finding the distance, I demonstrated a few examples of the indexes where I expressed how one can use those indexes to find these distances and how they can improve the performance of similar query. I also demonstrated few examples wherein we were able to see in which data type the Index is most useful. We finished the demos with a few more internal stuff. Pinal Presenting session at TechEd India 2010 Despite all issues, I was mostly satisfied with my presentation. I think it was the best session I have ever presented at any conference. There was no help from Technology for a while, but I still got lots of appreciation at the end. When we ended the session, the applause from the audience was so loud that for a moment, the rain was not audible. I was truly moved by the dedication of the Technology enthusiasts. Pinal Dave After Presenting session at TechEd India 2010 The abstract of the session is as follows: The Microsoft SQL Server 2008 delivers new spatial data types that enable you to consume, use, and extend location-based data through spatial-enabled applications. Attend this session to learn how to use spatial functionality in next version of SQL Server to build and optimize spatial queries. This session outlines the new geography data type to store geodetic spatial data and perform operations on it, use the new geometry data type to store planar spatial data and perform operations on it, take advantage of new spatial indexes for high performance queries, use the new spatial results tab to quickly and easily view spatial query results directly from within Management Studio, extend spatial data capabilities by building or integrating location-enabled applications through support for spatial standards and specifications and much more. Time: 8:00 PM – onwards Dinner by Sponsors After the lively session during the day, there was another dinner party courtesy of one of the sponsors of TechEd. All the MVPs and several Community leaders were present at the dinner. I would like to express my gratitude to Abhishek Kant for organizing this wonderful event for us. It was a blast and really relaxing in all angles. We all stayed there for a long time and talked about our sweet and unforgettable memories of the event. Pinal Dave and Bijoy Singhal It was really one wonderful event. After writing this much, I say that I have no words to express about how much I enjoyed TechEd. However, it is true that I shared with you only 1% of the total activities I have done at the event. There were so many people I have met, yet were not mentioned here although I wanted to write their names here, too . Anyway, I have learned so many things and up until now, I am not able to get over all the fun I had in this event. Pinal Dave at TechEd India 2010 The Next Days – April 15, 2010 – till today I am still not able to get my mind out of the whole experience I had at TechEd India 2010. It was like a whole Microsoft Family working together to celebrate a happy occasion. TechEd India – Truly An Unforgettable Experience!

    TechEd India was one of the largest Technology events in India led by Microsoft. This event was attended by more than 3,000 technology enthusiasts, making it one of the most well-organized events of the year. Though I attempted to attend almost all the technology events here, I have not seen any bigger or better event in Indian subcontinents other than this. There are 21 Technical Tracks at Tech·Ed India 2010 that span more than 745 learning opportunities. I was fortunate enough to be a part of this whole event as a speaker and a delegate, as well. TechEd India Speaker Badge and A Token of Lifetime Hotel Selection I presented three different sessions at TechEd India and was also a part of panel discussion. (The details of the sessions are given at the end of this blog post.) Due to extensive traveling, I stay away from my family occasionally. For this reason, I took my wife – Nupur and daughter Shaivi (8 months old) to the event along with me. We stayed at the same hotel where the event was organized so as to maximize my time bonding with my family and to have more time in networking with technology community, at the same time. The hotel Lalit Ashok is the largest and most luxurious venue one can find in Bangalore, located in the middle of the city. The cost of the hotel was a bit pricey, but looking at all the advantages, I had decided to ask for a booking there. Hotel Lalit Ashok Nupur Dave and Shaivi Dave Arrival Day – DAY 0 – April 11, 2010 I reached the event a day earlier, and that was one wise decision for I was able to relax a bit and go over my presentation for the next day’s course. I am a kind of person who likes to get everything ready ahead of time. I was also able to enjoy a pleasant evening with several Microsoft employees and my family friends. I even checked out the location where I would be doing presentations the next day. I was fortunate enough to meet Bijoy Singhal from Microsoft who helped me out with a few of the logistics issues that occured the day before. I was not aware of the fact that the very next day he was going to be “The Man” of the TechEd 2010 event. Vinod Kumar from Microsoft was really very kind as he talked to me regarding my subsequent session. He gave me some suggestions which were really helpful that I was able to incorporate them during my presentation. Finally, I was able to meet Abhishek Kant from Microsoft; his valuable suggestions and unlimited passion have inspired many people like me to work with the Community. Pradipta from Microsoft was also around, being extremely busy with logistics; however, in those busy times, he did find some good spare time to have a chat with me and the other Community leaders. I also met Harish Ranganathan and Sachin Rathi, both from Microsoft. It was so interesting to listen to both of them talking about SharePoint. I just have no words to express my overwhelmed spirit because of all these passionate young guys - Pradipta,Vinod, Bijoy, Harish, Sachin and Ahishek (of course!). Map of TechEd India 2010 Event Day 1 – April 12, 2010 From morning until night time, today was truly a very busy day for me. I had two presentations and one panel discussion for the day. Needless to say, I had a few meetings to attend as well. The day started with a keynote from S. Somaseger where he announced the launch of Visual Studio 2010. The keynote area was really eye-catching because of the very large, bigger-than- life uniform screen. This was truly one to show. The title music of the keynote was very interesting and it featured Bijoy Singhal as the model. It was interesting to talk to him afterwards, when we laughed at jokes together about his modeling assignment. TechEd India Keynote Opening Featuring Bijoy TechEd India 2010 Keynote – S. Somasegar Time: 11:15pm – 11:45pm Session 1: True Lies of SQL Server – SQL Myth Buster Following the excellent keynote, I had my very first session on the subject of SQL Server Myth Buster. At first, I was a bit nervous as right after the keynote, for this was my very first session and during my presentation I saw lots of Microsoft Product Team members. Well, it really went well and I had a really good discussion with attendees of the session. I felt that a well begin was half-done and my confidence was regained. Right after the session, I met a few of my Community friends and had meaningful discussions with them on many subjects. The abstract of the session is as follows: In this 30-minute demo session, I am going to briefly demonstrate few SQL Server Myths and their resolutions as I back them up with some demo. This demo presentation is a must-attend for all developers and administrators who would come to the event. This is going to be a very quick yet fun session. Pinal Presenting session at TechEd India 2010 Time: 1:00 PM – 2:00 PM Lunch with Somasegar After the session I went to see my daughter, and then I headed right away to the lunch with S. Somasegar – the keynote speaker and senior vice president of the Developer Division at Microsoft. I really thank to Abhishek who made it possible for us. Because of his efforts, all the MVPs had the opportunity to meet such a legendary person and had to talk with them on Microsoft Technology. Though Somasegar is currently holding such a high position in Microsoft, he is very polite and a real gentleman, and how I wish that everybody in industry is like him. Believe me, if you spread love and kindness, then that is what you will receive back. As soon as lunch time was over, I ran to the session hall as my second presentation was about to start. Time: 2:30pm – 3:30pm Session 2: Master Data Services in Microsoft SQL Server 2008 R2 Business Intelligence is a subject which was widely talked about at TechEd. Everybody was interested in this subject, and I did not excuse myself from this great concept as well. I consider myself fortunate as I was presenting on the subject of Master Data Services at TechEd. When I had initially learned this subject, I had a bit of confusion about the usage of this tool. Later on, I decided that I would tackle about how we all developers and DBAs are not able to understand something so simple such as this, and even worst, creating confusion about the technology. During system designing, it is very important to have a reference material or master lookup tables. Well, I talked about the same subject and presented the session keeping that as my center talk. The session went very well and I received lots of interesting questions. I got many compliments for talking about this subject on the real-life scenario. I really thank Rushabh Mehta (CEO, Solid Quality Mentors India) for his supportive suggestions that helped me prepare the slide deck, as well as the subject. Pinal Presenting session at TechEd India 2010 The abstract of the session is as follows: SQL Server Master Data Services will ship with SQL Server 2008 R2 and will improve Microsoft’s platform appeal. This session provides an in-depth demonstration of MDS features and highlights important usage scenarios. Master Data Services enables consistent decision-making process by allowing you to create, manage and propagate changes from a single master view of your business entities. Also, MDS – Master Data-hub which is a vital component, helps ensure the consistency of reporting across systems and deliver faster and more accurate results across the enterprise. We will talk about establishing the basis for a centralized approach to defining, deploying, and managing master data in the enterprise. Pinal Presenting session at TechEd India 2010 The day was still not over for me. I had ran into several friends but we were not able keep our enthusiasm under control about all the rumors saying that SQL Server 2008 R2 was about to be launched tomorrow in the keynote. I then ran to my third and final technical event for the day- a panel discussion with the top technologies of India. Time: 5:00pm – 6:00pm Panel Discussion: Harness the power of Web – SEO and Technical Blogging As I have delivered two technical sessions by this time, I was a bit tired but  not less enthusiastic when I had to talk about Blog and Technology. We discussed many different topics there. I told them that the most important aspect for any blog is its content. We discussed in depth the issues with plagiarism and how to avoid it. Another topic of discussion was how we technology bloggers can create awareness in the Community about what the right kind of blogging is and what morally and technically wrong acts are. A couple of questions were raised about what type of liberty a person can have in terms of writing blogs. Well, it was generically agreed that a blog is mainly a representation of our ideas and thoughts; it should not be governed by external entities. As long as one is writing what they really want to say, but not providing incorrect information or not practicing plagiarism, a blogger should be allowed to express himself. This panel discussion was supposed to be over in an hour, but the interest of the participants was remarkable and so it was extended for 30 minutes more. Finally, we decided to bring to a close the discussion and agreed that we will continue the topic next year. TechEd India Panel Discussion on Web, Technology and SEO Surprisingly, the day was just beginning after doing all of these. By this time, I have almost met all the MVP who arrived at the event, as well as many Microsoft employees. There were lots of Community folks present, too. I decided that I would go to meet several friends from the Community and continue to communicate with me on SQLAuthority.com. I also met Abhishek Baxi and had a good talk with him regarding Win Mobile and Twitter. He also took a very quick video of me wherein I spoke in my mother’s tongue, Gujarati. It was funny that I talked in Gujarati almost all the day, but when I was talking in the interview I could not find the right Gujarati words to speak. I think we all think in English when we think about Technology, so as to address universality. After meeting them, I headed towards the Speakers’ Dinner. Time: 8:00 PM – onwards Speakers Dinner The Speakers’ dinner was indeed a wonderful opportunity for all the speakers to get together and relax. We talked so many different things, from XBOX to Hindi Movies, and from SQL to Samosas. I just could not express how much fun I had. After a long evening, when I returned tmy room and met Shaivi, I just felt instantly relaxed. Kids are really gifts from God. Today was a really long but exciting day. So many things happened in just one day: Visual Studio Lanch, lunch with Somasegar, 2 technical sessions, 1 panel discussion, community leaders meeting, speakers dinner and, last but not leas,t playing with my child! A perfect day! Day 2 – April 13, 2010 Today started with a bang with the excellent keynote by Kamal Hathi who launched SQL Server 2008 R2 in India and demonstrated the power of PowerPivot to all of us. 101 Million Rows in Excel brought lots of applause from the audience. Kamal Hathi Presenting Keynote at TechEd India 2010 The day was a bit easier one for me. I had no sessions today and no events planned. I had a few meetings planned for the second day of the event. I sat in the speaker’s lounge for half a day and met many people there. I attended nearly 9 different meetings today. The subjects of the meetings were very different. Here is a list of the topics of the Community-related meetings: SQL PASS and its involvement in India and subcontinents How to start community blogging Forums and developing aptitude towards technology Ahmedabad/Gandhinagar User Groups and their developments SharePoint and SQL Business Meeting – a client meeting Business Meeting – a potential performance tuning project Business Meeting – Solid Quality Mentors (SolidQ) And family friends Pinal Dave at TechEd India The day passed by so quickly during this meeting. In the evening, I headed to Partners Expo with friends and checked out few of the booths. I really wanted to talk about some of the products, but due to the freebies there was so much crowd that I finally decided to just take the contact details of the partner. I will now start sending them with my queries and, hopefully, I will have my questions answered. Nupur and Shaivi had also one meeting to attend; it was with our family friend Vijay Raj. Vijay is also a person who loves Technology and loves it more than anybody. I see him growing and learning every day, but still remaining as a ‘human’. I believe that if someone acquires as much knowledge as him, that person will become either a computer or cyborg. Here, Vijay is still a kind gentleman and is able to stay as our close family friend. Shaivi was really happy to play with Uncle Vijay. Pinal Dave and Vijay Raj Renuka Prasad, a Microsoft MVP, impressed me with his passion and knowledge of SQL. Every time he gives me credit for his success, I believe that he is very humble. He has way more certifications than me and has worked many more years with SQL compared to me. He is an excellent photographer as well. Most of the photos in this blog post have been taken by him. I told him if ever he wants to do a part time job, he can do the photography very well. Pinal Dave and Renuka Prasad I also met L Srividya from Microsoft, whom I was looking forward to meet. She is a bundle of knowledge that everyone would surely learn a lot from her. I was able to get a few minutes from her and well, I felt confident. She enlightened me with SQL Server BI concepts, domain management and SQL Server security and few other interesting details. I also had a wonderful time talking about SharePoint with fellow Solid Quality Mentor Joy Rathnayake. He is very passionate about SharePoint but when you talk .NET and SQL with him, he is still overwhelmingly knowledgeable. In fact, while talking to him, I figured out that the recent training he delivered was on SQL Server 2008 R2. I told him a joke that it hurts my ego as he is more popular now in SQL training and consulting than me. I am sure all of you agree that working with good people is a gift from God. I am fortunate enough to work with the best of the best Industry experts. It was a great pleasure to hang out with my Community friends – Ahswin Kini, HimaBindu Vejella, Vasudev G, Suprotim Agrawal, Dhananjay, Vikram Pendse, Mahesh Dhola, Mahesh Mitkari,  Manu Zacharia, Shobhan, Hardik Shah, Ashish Mohta, Manan, Subodh Sohani and Sanjay Shetty (of course!) .  (Please let me know if I have met you at the event and forgot your name to list here). Time: 8:00 PM – onwards Community Leaders Dinner After lots of meetings, I headed towards the Community Leaders dinner meeting and met almost all the folks I met in morning. The discussion was almost the same but the real good thing was that we were enjoying it. The food was really good. Nupur was invited in the event, but Shaivi could not come. When Nupur tried to enter the event, she was stopped as Shaivi did not have the pass to enter the dinner. Nupur expressed that Shaivi is only 8 months old and does not eat outside food as well and could not stay by herself at this age, but the door keeper did not agree and asked that without the entry details Shaivi could not go in, but Nupur could. Nupur called me on phone and asked me to help her out. By the time, I was outside; the organizer of the event reached to the door and happily approved Shaivi to join the party. Once in the party, Shaivi had lots of fun meeting so many people. Shaivi Dave and Abhishek Kant Dean Guida (Infragistics President and CEO) and Pinal Dave (SQLAuthority.com) Day 3 – April 14, 2010 Though, it was last day, I was very much excited today as I was about to present my very favorite session. Query Optimization and Performance Tuning is my domain expertise and I make my leaving by consulting and training the same. Today’s session was on the same subject and as an additional twist, another subject about Spatial Database was presented. I was always intrigued with Spatial Database and I have enjoyed learning about it; however, I have never thought about Spatial Indexing before it was decided that I will do this session. I really thank Solid Quality Mentor Dr. Greg Low for his assistance in helping me prepare the slide deck and also review the content. Furthermore, today was really what I call my ‘learning day’ . So far I had not attended any session in TechEd and I felt a bit down for that. Everybody spends their valuable time & money to learn something new and exciting in TechEd and I had not attended a single session at the moment thinking that it was already last day of the event. I did have a plan for the day and I attended two technical sessions before my session of spatial database. I attended 2 sessions of Vinod Kumar. Vinod is a natural storyteller and there was no doubt that his sessions would be jam-packed. People attended his sessions simply because Vinod is syhe speaker. He did not have a single time disappointed audience; he is truly a good speaker. He knows his stuff very well. I personally do not think that in India he can be compared to anyone for SQL. Time: 12:30pm-1:30pm SQL Server Query Optimization, Execution and Debugging Query Performance I really had a fun time attending this session. Vinod made this session very interactive. The entire audience really got into the presentation and started participating in the event. Vinod was presenting a small problem with Query Tuning, which any developer would have encountered and solved with their help in such a fashion that a developer feels he or she have already resolved it. In one question, I was the only one who was ready to answer and Vinod told me in a light tone that I am now allowed to answer it! The audience really found it very amusing. There was a huge crowd around Vinod after the session. Vinod – A master storyteller! Time: 3:45pm-4:45pm Data Recovery / consistency with CheckDB This session was much heavier than the earlier one, and I must say this is my most favorite session I EVER attended in India. In this TechEd I have only attended two sessions, but in my career, I have attended numerous technical sessions not only in India, but all over the world. This session had taken my breath away. One by one, Vinod took the different databases, and started to corrupt them in different ways. Each database has some unique ways to get corrupted. Once that was done, Vinod started to show the DBCC CEHCKDB and demonstrated how it can solve your problem. He finally fixed all the databases with this single tool. I do have a good knowledge of this subject, but let me honestly admit that I have learned a lot from this session. I enjoyed and cheered during this session along with other attendees. I had total satisfaction that, just like everyone, I took advantage of the event and learned something. I am now TECHnically EDucated. Pinal Dave and Vinod Kumar After two very interactive and informative SQL Sessions from Vinod Kumar, the next turn me presenting on Spatial Database and Indexing. I got once again nervous but Vinod told me to stay natural and do my presentation. Well, once I got a huge stage with a total of four projectors and a large crowd, I felt better. Time: 5:00pm-6:00pm Session 3: Developing with SQL Server Spatial and Deep Dive into Spatial Indexing Pinal Presenting session at TechEd India 2010 Pinal Presenting session at TechEd India 2010 I kicked off this session with Michael J Swart‘s beautiful spatial image. This session was the last one for the day but, to my surprise, I had more than 200+ attendees. Slowly, the rain was starting outside and I was worried that the hall would not be full; despite this, there was not a single seat available in the first five minutes of the session. Thanks to all of you for attending my presentation. I had demonstrated the map of world (and India) and quickly explained what  Geographic and Geometry data types in Spatial Database are. This session had interesting story of Indexing and Comparison, as well as how different traditional indexes are from spatial indexing. Pinal Presenting session at TechEd India 2010 Due to the heavy rain during this event, the power went off for about 22 minutes (just an accident – nobodies fault). During these minutes, there were no audio, no video and no light. I continued to address the mass of 200+ people without any audio device and PowerPoint. I must thank the audience because not a single person left from the session. They all stayed in their place, some moved closure to listen to me properly. I noticed that the curiosity and eagerness to learn new things was at the peak even though it was the very last session of the TechEd. Everybody wanted get the maximum knowledge out of this whole event. I was touched by the support from audience. They listened and participated in my session even without any kinds of technology (no ppt, no mike, no AC, nothing). During these 22 minutes, I had completed my theory verbally. Pinal Presenting session at TechEd India 2010 After a while, we got the projector back online and we continued with some exciting demos. Many thanks to Microsoft people who worked energetically in background to get the backup power for project up. I had a very interesting demo wherein I overlaid Bangalore and Hyderabad on the India Map and find their aerial distance between them. After finding the aerial distance, we browsed online and found that SQL Server estimates the exact aerial distance between these two cities, as compared to the factual distance. There was a huge applause from the crowd on the subject that SQL Server takes into the count of the curvature of the earth and finds the precise distances based on details. During the process of finding the distance, I demonstrated a few examples of the indexes where I expressed how one can use those indexes to find these distances and how they can improve the performance of similar query. I also demonstrated few examples wherein we were able to see in which data type the Index is most useful. We finished the demos with a few more internal stuff. Pinal Presenting session at TechEd India 2010 Despite all issues, I was mostly satisfied with my presentation. I think it was the best session I have ever presented at any conference. There was no help from Technology for a while, but I still got lots of appreciation at the end. When we ended the session, the applause from the audience was so loud that for a moment, the rain was not audible. I was truly moved by the dedication of the Technology enthusiasts. Pinal Dave After Presenting session at TechEd India 2010 The abstract of the session is as follows: The Microsoft SQL Server 2008 delivers new spatial data types that enable you to consume, use, and extend location-based data through spatial-enabled applications. Attend this session to learn how to use spatial functionality in next version of SQL Server to build and optimize spatial queries. This session outlines the new geography data type to store geodetic spatial data and perform operations on it, use the new geometry data type to store planar spatial data and perform operations on it, take advantage of new spatial indexes for high performance queries, use the new spatial results tab to quickly and easily view spatial query results directly from within Management Studio, extend spatial data capabilities by building or integrating location-enabled applications through support for spatial standards and specifications and much more. Time: 8:00 PM – onwards Dinner by Sponsors After the lively session during the day, there was another dinner party courtesy of one of the sponsors of TechEd. All the MVPs and several Community leaders were present at the dinner. I would like to express my gratitude to Abhishek Kant for organizing this wonderful event for us. It was a blast and really relaxing in all angles. We all stayed there for a long time and talked about our sweet and unforgettable memories of the event. Pinal Dave and Bijoy Singhal It was really one wonderful event. After writing this much, I say that I have no words to express about how much I enjoyed TechEd. However, it is true that I shared with you only 1% of the total activities I have done at the event. There were so many people I have met, yet were not mentioned here although I wanted to write their names here, too . Anyway, I have learned so many things and up until now, I am not able to get over all the fun I had in this event. Pinal Dave at TechEd India 2010 The Next Days – April 15, 2010 – till today I am still not able to get my mind out of the whole experience I had at TechEd India 2010. It was like a whole Microsoft Family working together to celebrate a happy occasion. TechEd India – Truly An Unforgettable Experience!

  • Why might login failures cause SQL 2005 to dump and ditch?

    - by Byron Sommardahl
    Our SQL 2005 server began timing out and finally stopped responding on Oct 26th. The application logs showed a ton of 17883 events leading up to a reboot. After the reboot everything was fine but we were still scratching our heads. Fast forward 6 days... it happened again. Then again 2 days later. The last night. Today it has happened three times to far. The timeline is fairly predictable when it happens: Trans log backups. Login failure for "user2". Minidump Another minidump for the scheduler Repeated 17883 events. Server fails little by little until it won't accept any requests. Reboot is all that gets us going again (a band-aid) Interesting, though, is that the server box itself doesn't seem to have any problems. CPU usage is normal. Network connectivity is fine. We can remote in and look at logs. Management studio does eventually bog down, though. Today, for the first time, we tried stopping services instead of a reboot. All services stopped on their own except for the SQL Server service. We finally did an "end task" on that one and were able to bring everything back up. It worked fine for about 30 minutes until we started seeing timeouts and 17883's again. This time, probably because we didn't reboot all the way, we saw a bunch of 844 events mixed in with the 17883's. Our entire tech team here is scratching heads... some ideas we're kicking around: MS Cumulative Update hit around the same time as when we first had a problem. Since then, we've rolled it back. Maybe it didn't rollback all the way. The situation looks and feels like an unhandled "stack overflow" (no relation) in that it starts small and compounds over time. Problem with this is that there isn't significant CPU usage. At any rate, we're not ruling SQL 2005 bug out at all. Maybe we added one too many import processes and have reached our limit on this box. (hard to believe). Looking at SQLDUMP0151.log at the time of one of the crashes. There are some "login failures" and then there are two stack dumps. 1st a normal stack dump, 2nd for a scheduler dump.

  • Cocoa QuickLook initiated by NSTableView Cell

    - by Tristan Seifert
    I have an NSTableView that contains 2 different Columns - one is an NSImageCell that shows a file icon, and the second is a custom subclass of NSTextFieldCell that contains a quick look button on the right of the text. When I click the Quick Look button, the following code is invoked: [[QLPreviewPanel sharedPreviewPanel] makeKeyAndOrderFront:nil]; This does it's job and shows the blank Quick Look panel saying "No Items Selected." After I did a bit of research on the internet, I implemented a custom NSTableView subclass to be the Delegate and Data Source for the Quick Look panel. I get the notification that Quick Look asks if I want to be the delegate, and I respond with return YES. Even though I implement all methods in both QLPreviewPanelDataSource and QLPreviewPanelDelegate, at runtime I get this error on the console: 2010-12-24 15:32:17.235 BackMeUp[4763:80f] clicked: ~/Desktop/HUDTape.mov 2010-12-24 15:32:17.489 BackMeUp[4763:80f] [QL] QLError(): -[QLPreviewPanel setDelegate:] called while the panel has no controller - Fix this or this will raise soon.

The first line above is just that I know the cell has been clicked. Anyways, here is the .m file of the custom table view subclass: // // BackupListTableView.m // BackMeUp // // Created by Tristan Seifert on 12/24/10. // Copyright 2010 24/7 Server.

  • Any tool to make git build every commit to a branch in a seperate repository?

    - by Wayne
    A git tool that meets the specs below is needed. Does one already exists? If not, I will create a script and make it available on GitHub for others to use or contribute. Is there a completely different and better way to solve the need to build/test every commit to a branch in a git repository? Not just to the latest but each one back to a certain staring point. Background: Our development environment uses a separate continuous integration server which is wonderful. However, it is still necessary to do full builds locally on each developer's PC to make sure the commit won't "break the build" when pushed to the CI server. Unfortunately, with auto unit tests, those build force the developer to wait 10 or 15 minutes for a build every time. To solve this we have setup a "mirror" git repository on each developer PC. So we develop in the main repository but anytime a local full build is needed. We run a couple commands in a in the mirror repository to fetch, checkout the commit we want to build, and build. It's works extremely lovely so we can continue working in the main one with the build going in parallel. There's only one main concern now. We want to make sure every single commit builds and tests fine. But we often get busy and neglect to build several fresh commits. Then if it the build fails you have to do a bisect or manually figure build each interim commit to figure out which one broke. Requirements for this tool. The tool will look at another repo, origin by default, fetch and compare all commits that are in branches to 2 lists of commits. One list must hold successfully built commits and the other lists commits that failed. It identifies any commit or commits not yet in either list and begins to build them in a loop in the order that they were committed. It stops on the first one that fails. The tool appropriately adds each commit to either the successful or failed list after it as attempted to build each one. The tool will ignore any "legacy" commits which are prior to the oldest commit in the success list. This logic makes the starting point possible in the next point. Starting Point. The tool building a specific commit so that, if successful it gets added to the success list. If it is the earliest commit in the success list, it becomes the "starting point" so that none of the commits prior to that are examined for builds. Only linear tree support? Much like bisect, this tool works best on a commit tree which is, at least from it's starting point, linear without any merges. That is, it should be a tree which was built and updated entirely via rebase and fast forward commits. If it fails on one commit in a branch it will stop without building the rest that followed after that one. Instead if will just move on to another branch, if any. The tool must do these steps once by default but allow a parameter to loop with an option to set how many seconds between loops. Other tools like Hudson or CruiseControl could do more fancy scheduling options. The tool must have good defaults but allow optional control. Which repo? origin by default. Which branches? all of them by default. What tool? by default an executable file to be provided by the user named "buildtest", "buildtest.sh" "buildtest.cmd", or buildtest.exe" in the root folder of the repository. Loop delay? run once by default with option to loop after a number of seconds between iterations.

  • Event receiver on Content Type not triggered on WikiPageLibrary

    - by Ciprian Grosu
    Hello all, I created a new content type for a wiki page library. I added this content type to library by code (the interface did not allow this). Next, I added an event receiver to this content type (on ItemAdded and ItemAdding). My problem is that no event is trrigered. If I add this events directly to the wiki page library all works fine. Is there a limitation/bug/trick ? I looked at the content type attached to the library with SharePoint Manager and in his schema the part for event receiver is missing...I know that there should be something like: <XmlDocuments> <XmlDocument NamespaceURI="http://schemas.microsoft.com/sharepoint/events"> <spe:Receivers xmlns:spe="http://schemas.microsoft.com/sharepoint/events"> <Receiver> <Name> </Name> <Type>1</Type> <SequenceNumber>10000</SequenceNumber> <Assembly>RssFeedWP, Version=1.0.0.0, Culture=neutral, PublicKeyToken=f6722cbeba696def</Assembly> <Class>RssFeedWP.ItemEventReceiver</Class> <Data> </Data> <Filter> </Filter> </Receiver> <Receiver> <Name> </Name> <Type>10001</Type> <SequenceNumber>10000</SequenceNumber> <Assembly>RssFeedWP, Version=1.0.0.0, Culture=neutral, PublicKeyToken=f6722cbeba696def</Assembly> <Class>RssFeedWP.ItemEventReceiver</Class> <Data> </Data> <Filter> </Filter> </Receiver> </spe:Receivers> </XmlDocument> If I look with SPM to the content type added to site I see this part into schema. Here is my code: public override void FeatureActivated(SPFeatureReceiverProperties properties) { using (SPWeb web = (SPWeb)properties.Feature.Parent) { // create RssWiki content type SPContentType rssFeedContentType = new SPContentType(web.AvailableContentTypes["Wiki Page"], web.ContentTypes, "RssFeed Wiki Page"); // add rssfeed url field to the new content type AddFieldToContentType(web, rssFeedContentType, "RssFeed Url", SPFieldType.Note); // add use xslt check box field to the new content type AddFieldToContentType(web, rssFeedContentType, "Use Xslt", SPFieldType.Boolean); // add xslt url field to the new content type AddFieldToContentType(web, rssFeedContentType, "Xslt Url", SPFieldType.Note); web.ContentTypes.Add(rssFeedContentType); rssFeedContentType.Update(); web.Update(); AddContentTypeToList(web, rssFeedContentType); AddEventReceiversToCT(rssFeedContentType); //AddEventReceiverToList(web); } } private void AddFieldToContentType(SPWeb web, SPContentType ct, string fieldName, SPFieldType fieldType) { SPField rssUrlField = null; try { rssUrlField = web.Fields.GetField(fieldName); } catch (Exception ex) { if (rssUrlField == null) { web.Fields.Add(fieldName, fieldType, false); } } SPFieldLink rssUrlFieldLink = new SPFieldLink(web.Fields[fieldName]); ct.FieldLinks.Add(rssUrlFieldLink); } private static void AddContentTypeToList(SPWeb web, SPContentType ct) { SPList wikiList = web.Lists[listName]; wikiList.ContentTypesEnabled = true; wikiList.ContentTypes.Add(ct); wikiList.Update(); } private static void AddEventReceiversToCT(SPContentType ct) { //add event receivers string assemblyName = System.Reflection.Assembly.GetExecutingAssembly().FullName; string ctReceiverName = "RssFeedWP.ItemEventReceiver"; ct.EventReceivers.Add(SPEventReceiverType.ItemAdding, assemblyName, ctReceiverName); ct.EventReceivers.Add(SPEventReceiverType.ItemAdded, assemblyName, ctReceiverName); ct.Update(); } Thx !

  • Parsing JSON into XML using Windows Phone

    - by Henry Edwards
    I have this code, but can't get it all working. I am trying to get a json string into xml. So that I can get a list of items when i parse the data. Is there a better way to parse json into xml. If so what's the best way to do it, and if possible could you give me a working example? The URL that is in the code is not the URL that i am using using System; using System.Collections.Generic; using System.Linq; using System.Net; using System.Windows; using System.Windows.Controls; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Animation; using System.Windows.Shapes; using Microsoft.Phone.Controls; using Newtonsoft.Json; using Newtonsoft.Json.Serialization; using Newtonsoft.Json.Converters; using Newtonsoft.Json.Utilities; using Newtonsoft.Json.Linq; using Newtonsoft.Json.Schema; using Newtonsoft.Json.Bson; using System.Xml; using System.Xml.Serialization; using System.Xml.Linq; using System.Xml.Linq.XDocument; using System.IO; namespace WindowsPhonePanoramaApplication3 { public partial class Page2 : PhoneApplicationPage { public Page2() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e1) { /* because the origional JSON string has multiple root's this needs to be added */ string json = "{BFBC2_GlobalStats:"; json += DownlodUrl("http://api.bfbcs.com/api/xbox360?globalstats"); json += "}"; XmlDocument doc = (XmlDocument)JsonConvert.DeserializeObject(json); textBox1.Text = GetXmlString(doc); } private string GetXmlString() { throw new NotImplementedException(); } private string DownlodUrl(string url) { string result = null; try { WebClient client = new WebClient(); result = client.DownloadString(url); } catch (Exception ex) { // handle error result = ex.Message; } return result; } private string GetXmlString(XmlDocument xmlDoc) { sw = new StringWriter(); XmlTextWriter xw = new XmlTextWriter(sw); xw.Formatting = System.Xml.Formatting.Indented; xmlDoc.WriteTo(xw); return sw.ToString(); } } } The URL outputs the following code: {"StopName":"Race Hill", "stopId":7553, "NaptanCode":"bridwja", "LongName":"Race Hill", "OperatorsCode1":" 5", "OperatorsCode2":" ", "OperatorsCode3":" ", "OperatorsCode4":"bridwja", "Departures":[ { "ServiceName":"", "Destination":"", "DepartureTimeAsString":"", "DepartureTime":"30/01/2012 00:00:00", "Notes":""}` Thanks for your responses. So Should i just leave the data a json and then view the data via that??? Is this a way to show the data from a json string. public void Load() { // form the URI UriBuilder uri = new UriBuilder("http://mysite.com/events.json"); WebClient proxy = new WebClient(); proxy.OpenReadCompleted += new OpenReadCompletedEventHandler(OnReadCompleted); proxy.OpenReadAsync(uri.Uri); } void OnReadCompleted(object sender, OpenReadCompletedEventArgs e) { if (e.Error == null) { var serializer = new DataContractJsonSerializer(typeof(EventList)); var events = (EventList)serializer.ReadObject(e.Result); foreach (var ev in events) { Items.Add(ev); } } } public ObservableCollection<EventDetails> Items { get; private set; } Edit: Have now kept the url as json and have now got it working by using the json way.
