  • Upcoming Events

    - by noreply(at)blogger.com (Thomas Kyte)
    I'll be doing four public events in the next week and a half or so. The first one is open to anyone - anywhere.  I'll be doing a live webinar on MAA - the Maximum Availability Architecture.  It will take place this Thursday April 12th at 10am PDT.  You should register online before then if you are interested.After that, I'll be off to Belfast Ireland to do a repeat of what I presented at Oracle OpenWorld in October.  This will be done in conjunction with Oracle and the UKOUG.  See http://www.ukoug.org/events/tom-kyte-seminar-and-asktom-live/ for details, it'll take place on Monday April 16th.When I'm done in Ireland - I'll be doing it all over again in London on Wednesday April 18th.  This is being put on by the UKOUG and details may be found here http://www.ukoug.org/events/tom-kyte-seminar/.Lastly - I'll be going from London to Las Vegas for IOUG's Collaborate.  I'll be doing a day of Real World Performance with Andrew Holdsworth and Graham Wood.  If you are going to Collaborate and want to spend all day Sunday in a technical session (probably cheaper than the tables....) - you might want to check it out.  Details on the session can be found here: http://events.ioug.org/p/cm/ld/fid=31#realHope to see you at one of the events... (well, I won't really see anyone at the first event but you know what I mean)

  • Anyone been successful changing their career without having to start over from scratch?

    - by Awaken
    I posted a similar question on careeroverflow, but stackoverflow is just way more active and has way more users, so hopefully someone out there can help answer. I am currently an embedded developer in the defense/aerospace world for a big company. While I like the benefits and the pay, it just isn't keeping me happy. The Paul Graham article: How To Do What You Love really struck home. The problem I face are my golden handcuffs. When I look at jobs out there, they all want 5+ years experience in that language with expertise in framework/tool/server A,B,C, etc... I have worked in C and C++ on the job (in a real-time embedded environment) with some small things in C# and Java. I'm learning Ruby now to expand my knowledge, but I don't consider myself an expert in anything right now. I'd love to work on desktop applications or web apps. Is it possible for someone like me to make the switch without going back to the start line? I'd love to leave the huge bureaucracy and work with some great developers. I'd be willing to work late and take a modest pay cut, but that isn't so clear just from a resume. For those that have altered their career path, how did you do it? For those people who are in charge of hiring, what can I do to help myself?

  • Hack a Linksys Router into a Ambient Data Monitor

    - by Jason Fitzpatrick
    If you have a data source (like a weather report, bus schedule, or other changing data set) you can pull it and display it with an ambient data monitor; this fun build combines a hacked Linksys router and a modified toy bus to display transit arrival times. John Graham-Cumming wanted to keep an eye on the current bus arrival time tables without constantly visiting the web site to check them. His workaround turns a hacked Linksys router, a display, a modified London city bus (you could hack apart a more project-specific enclosure, of course), and a simple bit code that polls the bus schedule’s API, into a cool ambient data monitor that displays the arrival time, in minutes, of the next two buses that will pass by his stop. The whole thing could easily be adapted to another API to display anything from stock prices to weather temps. Hit up the link below for more information on the project.

  • Are there any concrete examples of where a paralellizing compiler would provide a value-adding benefit?

    - by jamie
    Paul Graham argues that: It would be great if a startup could give us something of the old Moore's Law back, by writing software that could make a large number of CPUs look to the developer like one very fast CPU. ... The most ambitious is to try to do it automatically: to write a compiler that will parallelize our code for us. There's a name for this compiler, the sufficiently smart compiler, and it is a byword for impossibility. But is it really impossible? Can someone provide a concrete example where a paralellizing compiler would solve a pain point? Web-apps don't appear to be a problem: just run a bunch of Node processes. Real-time raytracing isn't a problem: the programmers are writing multi-threaded, SIMD assembly language quite happily (indeed, some might complain if we make it easier!). The holy grail is to be able to accelerate any program, be it MySQL, Garage Band, or Quicken. I'm looking for a middle ground: is there a real-world problem that you have experienced where a "smart-enough" compiler would have provided a real benefit, i.e that someone would pay for? A good answer is one where there is a process where the computer runs at 100% CPU on a single core for a painful period of time. That time might be 10 seconds, if the task is meant to be quick. It might be 500ms if the task is meant to be interactive. It might be 10 hours. Please describe such a problem. Really, that's all I'm looking for: candidate areas for further investigation. (Hence, raytracing is off the list because all the low-hanging fruit have been feasted upon.) I am not interested in why it cannot be done. There are a million people willing to point to the sound reasons why it cannot be done. Such answers are not useful.

  • Last week I was presented with a Microsoft MVP award in Virtual Machines – time to thank all who hel

    - by Liam Westley
    MVP in Virtual Machines Last week, on 1st April, I received an e-mail from Microsoft letting me know that I had been presented with a 2010 Microsoft® MVP Award for outstanding contributions in Virtual Machine technical communities during the past year.   It was an honour to be nominated, and is a great reflection on the vibrancy of the UK user group community which made this possible. Virtualisation for developers, not just IT Pros I consider it a special honour as my expertise in virtualisation is as a software developer utilising virtual machines to aid my software development, rather than an IT Pro who manages data centre and network infrastructure.  I’ve been on a minor mission over the past few years to enthuse developers in a topic usually seen as only for network admins, but which can make their life a whole lot easier once understood properly. Continuous learning is fun In 1676, the scientist Isaac Newton, in a letter to Robert Hooke used the phrase (http://www.phrases.org.uk/meanings/268025.html) ‘If I have seen a little further it is by standing on the shoulders of Giants’ I’m a nuclear physicist by education, so I am more than comfortable that any knowledge I have is based on the work of others.  Although far from a science, software development and IT is equally built upon the work of others. It’s one of the reasons I despise software patents. So in that sense this MVP award is a result of all the great minds that have provided virtualisation solutions for me to talk about.  I hope that I have always acknowledged those whose work I have used when blogging or giving presentations, and that I have executed my responsibility to share any knowledge gained as widely as possible. Thanks to all those who helped – a big thanks to the UK user group community I reckon this journey started in 2003 when I started attending a user group called the London .Net Users Group (http://www.dnug.org.uk) started by a nice chap called Ian Cooper. The great thing about Ian was that he always encouraged non professional speakers to take the stage at the user group, and my first ever presentation was on 30th September 2003; SQL Server CE 2.0 and the.NET Compact Framework. In 2005 Ian Cooper was on the committee for the first DeveloperDeveloperDeveloper! day, the free community conference held at Microsoft’s UK HQ in Thames Valley park in Reading.  He encouraged me to take part and so on 14th May 2005 I presented a talk previously given to the London .Net User Group on Simplifying access to multiple DB providers in .NET.  From that point on I definitely had the bug; presenting at DDD2, DDD3, groking at DDD4 and SQLBits I and after a break, DDD7, DDD Scotland and DDD8.  What definitely made me keen was the encouragement and infectious enthusiasm of some of the other DDD organisers; Craig Murphy, Barry Dorrans, Phil Winstanley and Colin Mackay. During the first few DDD events I met the Dave McMahon and Richard Costall from NxtGenUG who made it easy to start presenting at their user groups.  Along the way I’ve met a load of great user group organisers; Guy Smith-Ferrier of the .Net Developer Network, Jimmy Skowronski of GL.Net and the double act of Ray Booysen and Gavin Osborn behind what was Vista Squad and is now Edge UG. Final thanks to those who suggested virtualisation as a topic ... Final thanks have to go the people who inspired me to create my Virtualisation for Developers talk.  Toby Henderson (@holytshirt) ensured I took notice of Sun’s VirtualBox, Peter Ibbotson for being a fine sounding board at the Kew Railway over quite a few Adnam’s Broadside and to Guy Smith-Ferrier for allowing his user group to be the guinea pigs for the talk before it was seen at DDD7.  Thanks to all of you I now know much more about virtualisation than I would have thought possible and it continues to be great fun. Conclusion If this was an academy award acceptance speech I would have been cut off after the first few paragraphs, so well done if you made it this far.  I’ll be doing my best to do justice to the MVP award and the UK community.  I’m fortunate in having a new employer who considers presenting at user groups as a good thing, so don’t expect me to stop any time soon. If you’ve never seen me in action, then you can view the original DDD7 Virtualisation for Developers presentation (filmed by the Microsoft Channel 9 team) as part of the full DDD7 video list here, http://www.craigmurphy.com/blog/?p=1591.  Also thanks to Craig Murphy’s fine video work you can also view my latest DDD8 presentation on Commercial Software Development, here, http://vimeo.com/9216563 P.S. If I’ve missed anyone out, do feel free to lambast me in comments, it’s your duty.

  • Thanks to .Net Developers Network in Bristol - Hyper-V for Developers slides not available for downl

    - by Liam Westley
    Thanks to the guys at .Net Developers Network (http://www.dotnetdevnet.com) for inviting me down to Bristol to present on Hyper-V for Developers.  There were some great questions and genuine interest, especially surprising for a topic that often has a soporific effect on developers. You can download the original PowerPoint file or the PDF complete with speaker notes from here, http://www.tigernews.co.uk/blog-twickers/dotnetdevnet/HyperV4Devs-PPT.zip http://www.tigernews.co.uk/blog-twickers/dotnetdevnet/HyperV4Devs-PDF.zip I should be back for DDD SouthWest (http://www.dddsouthwest.com).  You can get voting from Monday 29th March 2010, and for a change my proposed topic is not about virtualisation! Finally, apologies to Guy Smith-Ferrier for dragging him away from the Bristol Girl Geek Dinners (http://bristolgirlgeekdinners.com) crew so I could catch my train back to London.

  • Creating Google+ profile has changed a Google Apps for Business email name

    - by inbanco
    We use Google Apps for business for email, docs etc. For one account [email protected] I setup a Google+ profile but didn't realise it would change the name of the email account Was: From email name: "Sydney Branch" Email address: [email protected] Now: From email name: "John Smith" Email address: [email protected] I'd like to change it back. The name hasn't changed though in the Google Apps domain management email section though, so i don't know what's going on and don't want to lose that email address/account through suspension. I couldn't care less about losing Google+, i'm happy to remove that profile, but would it revert the name?

  • SQL SERVER – Solution – Puzzle – Statistics are not Updated but are Created Once

    - by pinaldave
    Earlier I asked puzzle why statistics are not updated. Read the complete details over here: Statistics are not Updated but are Created Once In the question I have demonstrated even though statistics should have been updated after lots of insert in the table are not updated.(Read the details SQL SERVER – When are Statistics Updated – What triggers Statistics to Update) In this example I have created following situation: Create Table Insert 1000 Records Check the Statistics Now insert 10 times more 10,000 indexes Check the Statistics – it will be NOT updated Auto Update Statistics and Auto Create Statistics for database is TRUE Now I have requested two things in the example 1) Why this is happening? 2) How to fix this issue? I have many answers – here is the how I fixed it which has resolved the issue for me. NOTE: There are multiple answers to this problem and I will do my best to list all. Solution: Create nonclustered Index on column City Here is the working example for the same. Let us understand this script and there is added explanation at the end. -- Execution Plans Difference -- Estimated Execution Plan Vs Actual Execution Plan -- Create Sample Database CREATE DATABASE SampleDB GO USE SampleDB GO -- Create Table CREATE TABLE ExecTable (ID INT, FirstName VARCHAR(100), LastName VARCHAR(100), City VARCHAR(100)) GO CREATE NONCLUSTERED INDEX IX_ExecTable1 ON ExecTable (City); GO -- Insert One Thousand Records -- INSERT 1 INSERT INTO ExecTable (ID,FirstName,LastName,City) SELECT TOP 1000 ROW_NUMBER() OVER (ORDER BY a.name) RowID, 'Bob', CASE WHEN  ROW_NUMBER() OVER (ORDER BY a.name)%2 = 1 THEN 'Smith' ELSE 'Brown' END, CASE WHEN ROW_NUMBER() OVER (ORDER BY a.name)%20 = 1 THEN 'New York' WHEN  ROW_NUMBER() OVER (ORDER BY a.name)%20 = 5 THEN 'San Marino' WHEN  ROW_NUMBER() OVER (ORDER BY a.name)%20 = 3 THEN 'Los Angeles' WHEN  ROW_NUMBER() OVER (ORDER BY a.name)%20 = 7 THEN 'La Cinega' WHEN  ROW_NUMBER() OVER (ORDER BY a.name)%20 = 13 THEN 'San Diego' WHEN  ROW_NUMBER() OVER (ORDER BY a.name)%20 = 17 THEN 'Las Vegas' ELSE 'Houston' END FROM sys.all_objects a CROSS JOIN sys.all_objects b GO -- Display statistics of the table sp_helpstats N'ExecTable', 'ALL' GO -- Select Statement SELECT FirstName, LastName, City FROM ExecTable WHERE City  = 'New York' GO -- Display statistics of the table sp_helpstats N'ExecTable', 'ALL' GO -- Replace your Statistics over here DBCC SHOW_STATISTICS('ExecTable', IX_ExecTable1); GO -------------------------------------------------------------- -- Round 2 -- Insert One Thousand Records -- INSERT 2 INSERT INTO ExecTable (ID,FirstName,LastName,City) SELECT TOP 1000 ROW_NUMBER() OVER (ORDER BY a.name) RowID, 'Bob', CASE WHEN  ROW_NUMBER() OVER (ORDER BY a.name)%2 = 1 THEN 'Smith' ELSE 'Brown' END, CASE WHEN ROW_NUMBER() OVER (ORDER BY a.name)%20 = 1 THEN 'New York' WHEN  ROW_NUMBER() OVER (ORDER BY a.name)%20 = 5 THEN 'San Marino' WHEN  ROW_NUMBER() OVER (ORDER BY a.name)%20 = 3 THEN 'Los Angeles' WHEN  ROW_NUMBER() OVER (ORDER BY a.name)%20 = 7 THEN 'La Cinega' WHEN  ROW_NUMBER() OVER (ORDER BY a.name)%20 = 13 THEN 'San Diego' WHEN  ROW_NUMBER() OVER (ORDER BY a.name)%20 = 17 THEN 'Las Vegas' ELSE 'Houston' END FROM sys.all_objects a CROSS JOIN sys.all_objects b GO -- Select Statement SELECT FirstName, LastName, City FROM ExecTable WHERE City  = 'New York' GO -- Display statistics of the table sp_helpstats N'ExecTable', 'ALL' GO -- Replace your Statistics over here DBCC SHOW_STATISTICS('ExecTable', IX_ExecTable1); GO -- Clean up Database DROP TABLE ExecTable GO When I created non clustered index on the column city, it also created statistics on the same column with same name as index. When we populate the data in the column the index is update – resulting execution plan to be invalided – this leads to the statistics to be updated in next execution of SELECT. This behavior does not happen on Heap or column where index is auto created. If you explicitly update the index, often you can see the statistics are updated as well. You can see this is for sure happening if you follow the tell of John Sansom. John Sansom‘s suggestion: That was fun! Although the column statistics are invalidated by the time the second select statement is executed, the query is not compiled/recompiled but instead the existing query plan is reused. It is the “next” compiled query against the column statistics that will see that they are out of date and will then in turn instantiate the action of updating statistics. You can see this in action by forcing the second statement to recompile. SELECT FirstName, LastName, City FROM ExecTable WHERE City = ‘New York’ option(RECOMPILE) GO Kevin Cross also have another suggestion: I agree with John. It is reusing the Execution Plan. Aside from OPTION(RECOMPILE), clearing the Execution Plan Cache before the subsequent tests will also work. i.e., run this before round 2: ————————————————————– – Clear execution plan cache before next test DBCC FREEPROCCACHE WITH NO_INFOMSGS; ————————————————————– Nice puzzle! Kevin As this was puzzle John and Kevin both got the correct answer, there was no condition for answer to be part of best practices. I know John and he is finest DBA around – his tremendous knowledge has always impressed me. John and Kevin both will agree that clearing cache either using DBCC FREEPROCCACHE and recompiling each query every time is for sure not good advice on production server. It is correct answer but not best practice. By the way, if you have better solution or have better suggestion please advise. I am open to change my answer and publish further improvement to this solution. On very separate note, I like to have clustered index on my Primary Key, which I have not mentioned here as it is out of the scope of this puzzle.

  • How can I approach creating an efficient algorithm for maximizing value with these specific constraints?

    - by sway
    I'm having trouble coming up with an approach that isn't n^2 for this problem. Here's a contrived, simplified version I've come up with: Let's say you're a company that needs 4 employees to launch in a new city, a manager, two salespeople, and a customer support rep, and you magically know how much impact every candidate will have and how much salary they require to take the job. Your table of potential employees looks something like this: Name Position Salary Impact Adam Smith Manager 60,000 11 Allison Brown Salesperson 40,000 9 Brad Stewart Manager 55,000 9 ...etc (thousands of records) What algorithmic approach can be taken to find the maximum "impact" while still filling all the positions and remaining under, say, a 200,000 budget? Thanks!

  • Trying to Integrate Five9 and Apptivio [on hold]

    - by David Mitchell
    Five9 is a calling system application and Apptivio will be used to store client information for purchased products. Specifically what I need is an example code that will allow me to access Five9's CRM system using the access key and transfer a persons first and last name, for example, to Apptivio. The issue is I have never dealt with this type of system and I cannot find any information for it other than the Web2Campaign that was sent to me by Five9. Lets say this is the code from Five9 F9key=first_name&F9key=last_name&first_name=jon&last_name=smith Once this information is placed into Five9 I must update Apptivio with this information. I am lost as to how to send this information to Apptivio.

  • Binding to a dictionary in Silverlight with INotifyPropertyChanged

    - by rip
    In silverlight, I can not get INotifyPropertyChanged to work like I want it to when binding to a dictionary. In the example below, the page binds to the dictionary okay but when I change the content of one of the textboxes the CustomProperties property setter is not called. The CustomProperties property setter is only called when CustomProperties is set and not when the values within it are set. I am trying to do some validation on the dictionary values and so am looking to run some code when each value within the dictionary is changed. Is there anything I can do here? C# public partial class MainPage : UserControl { public MainPage() { InitializeComponent(); MyEntity ent = new MyEntity(); ent.CustomProperties.Add("Title", "Mr"); ent.CustomProperties.Add("FirstName", "John"); ent.CustomProperties.Add("Name", "Smith"); this.DataContext = ent; } } public class MyEntity : INotifyPropertyChanged { public event PropertyChangedEventHandler System.ComponentModel.INotifyPropertyChanged.PropertyChanged; public delegate void PropertyChangedEventHandler(object sender, System.ComponentModel.PropertyChangedEventArgs e); private Dictionary<string, object> _customProps; public Dictionary<string, object> CustomProperties { get { if (_customProps == null) { _customProps = new Dictionary<string, object>(); } return _customProps; } set { _customProps = value; if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs("CustomProperties")); } } } } VB Partial Public Class MainPage Inherits UserControl Public Sub New() InitializeComponent() Dim ent As New MyEntity ent.CustomProperties.Add("Title", "Mr") ent.CustomProperties.Add("FirstName", "John") ent.CustomProperties.Add("Name", "Smith") Me.DataContext = ent End Sub End Class Public Class MyEntity Implements INotifyPropertyChanged Public Event PropertyChanged(ByVal sender As Object, ByVal e As System.ComponentModel.PropertyChangedEventArgs) Implements System.ComponentModel.INotifyPropertyChanged.PropertyChanged Private _customProps As Dictionary(Of String, Object) Public Property CustomProperties As Dictionary(Of String, Object) Get If _customProps Is Nothing Then _customProps = New Dictionary(Of String, Object) End If Return _customProps End Get Set(ByVal value As Dictionary(Of String, Object)) _customProps = value RaiseEvent PropertyChanged(Me, New PropertyChangedEventArgs("CustomProperties")) End Set End Property End Class Xaml <TextBox Height="23" Name="TextBox1" Text="{Binding Path=CustomProperties[Title], Mode=TwoWay}" /> <TextBox Height="23" Name="TextBox2" Text="{Binding Path=CustomProperties[FirstName], Mode=TwoWay}" /> <TextBox Height="23" Name="TextBox3" Text="{Binding Path=CustomProperties[Name], Mode=TwoWay}" />
