  • Who created that user?

    - by AaronBertrand
    Twitter has provided some great fodder for blog content lately. And twice this week, I've found an excuse to take advantage of the default trace. Tonight @meltondba asked: I'm trying to find who created a user act in a DB It is true, SQL Server doesn't really keep track of who created objects, such as user accounts in a database. You can get some of this information from the default trace, though, since it tracks EventClass 109 (Audit Add DB User). If you run this code: USE [master] ; GO CREATE LOGIN...(read more)

  • Getting ID of an instance newly launched with ec2-api-tools

    - by Jonik
    I'm launching an EC2 instance, by invoking ec2-run-instances from simple a bash script, and want to perform further operations on that instance (e.g. associate elastic IP), for which I need the instance id. The command is something like ec2-run-instances ami-dd8ea5a9 -K pk.pem -C cert.pem --region eu-west-1 -t c1.medium -n 1, and its output: RESERVATION r-b6ea58c1 696664755663 default INSTANCE i-945af9e3 ami-dd8ea5b9 pending 0 c1.medium 2010-04-15T10:47:56+0000 eu-west-1a aki-b02a01c4 ari-39c2e94d In this example, i-945af9e3 is the id I'm after. So, I'd need a simple way to parse the id from what the command returns - how would you go about doing it? My AWK is a little rusty... Feel free to use any tool available on a typical Linux box. (If there's a way to get it directly using EC2-API-tools, all the better. But afaik there's no EC2 command to e.g. return the id of the most recently launched instance.)

  • C# Using singleton instead of a global static instance

    - by Farstucker
    I ran into a problem today and a friend recommended I use a global static instance or more elegantly a singleton pattern. I spent a few hours reading about singletons but a few things still escape me. Background: What Im trying to accomplish is creating an instance of an API and use this one instance in all my classes (as opposed to making a new connection, etc). There seems to be about 100 ways of creating a singleton but with some help from yoda I found some thread safe examples. ..so given the following code: public sealed class Singleton { public static Singleton Instance { get; private set; } static Singleton() { Instance = new Singleton(); } } How/Where would you instantiate the this new class and how should it be called from a separate class? Thanks for your help.

  • Exposing a "dumbed-down", read-only instance of a Model in GAE

    - by Blixt
    Does anyone know a clever way, in Google App Engine, to return a wrapped Model instance that only exposes a few of the original properties, and does not allow saving the instance back to the datastore? I'm not looking for ways of actually enforcing these rules, obviously it'll still be possible to change the instance by digging through its __dict__ etc. I just want a way to avoid accidental exposure/changing of data. My initial thought was to do this (I want to do this for a public version of a User model): class ReadOnlyUser(db.Model): display_name = db.StringProperty() @classmethod def kind(cls): return 'User' def put(self): raise SomeError() Unfortunately, GAE maps the kind to a class early on, so if I do ReadOnlyUser.get_by_id(1) I will actually get a User instance back, not a ReadOnlyUser instance.

  • Retrieve a user's Exchange database in powershell

    - by Paul
    Hey Everyone, I've scoured the interwebs for a few days now off and on to find this. I am creating a powershell script for email-enabling new user's(Exchange 2007). To give you a little background when we have a new hire, their AD account is created at our off-site helpdesk, but they don't create their email account. I'm trying to automate the process of mail-enabling the user which involves putting them in the same database as an existing user, disable imap pop activesync, and lastly email the requester of the ticket. I would like to just get prompted for the New User's name, User to Replicate(mailbox, storage group, database), and the person to email after it's been created. So if someone could just help with a command to Retrieve a user's Exchange database in powershell that would be great, but if people also want to help with my hacked up script please do so as well!!! Here is what I have so far: Write-output “ENTER THE FOLLOWING DETAILS” $DName = Read-Host “User Diplay Name" $RUser = Read-Host "Replicate User(Database Grab)" ***$RData = #get the Replicate user's mailbox database here*** $REmail = #either just use a Read-Host “Requester's Email address" or ask for Requester's name and pipe through their email address by digging for it w/ powershell Enable-Mailbox -Identity "$DName" -Database "$RData" Send-MailMessage -From "John Doe <[email protected]>" -To (put $REmail here which is the Requester's email) -Subject "Test Person's email account" -Body "Test Person's email account has been setup.`n`n`nJohn Doe`nGeneric Company`nSystems Administrator`nOffice: 123.456.7890`[email protected]" -SmtpServer genericexchange.exchange.com

  • Site Review: Facebook.com and Blockbuster.com - Navigation Schemes

    After cycling through a list of my favorite sites I decided to select Facebook.com and Blockbuster.com for this  post because I found their navigation schemes very intuitive. Facebook in my opinion took a very simplistic and minimalistic approach when they designed their site and its navigation. For example, when you login to your account you will find on the upper left hand side a generic section of the site common areas to all users like news, messages, events, photos and friends. Below this in a separate navigation menu is a list of applications that a user has elected to access through bookmarks. Finally in the upper right hand corner of the site contains links to administer the user’s account like account settings, public profile, and a link back to the users’ home page. Blockbuster on the other had tried to make site navigation a little more slick by using a menu-submenu approach to navigation where user can click on things like Rent, Buy, On Demand, Games, Stores, and Gifts and a submenu of corresponding items appears below the original menu item. In addition they also took this approach and added categorized lists of movies that they offer on the homepage so that users can click on an item like “DVD Spotlight” and a list of movies represented as actual DVD box cases appear on the user’s screen so they can scroll through the list by using left and right arrows on either side of the images displayed. Both Facebook and Blockbuster have more than one navigation groupings because their respected sites are so large and offer an absorbent amount of features. Because of this reason they have to group the main functionality of information in to logical groups based on their actions they perform and the access to specific information. For example it would not make sense for Facebook to include a particular game you like to play within your account with a section pertaining to account administration. The game link would be completely out of place and really confuse the users experience because the groupings where not logically grouped. In addition I think that Facebook users would benefit if Facebook allowed its users to specify what they want on the general navigation from within their site or at least create a section to show frequently accessed pages or favorite sections. Finally regarding additional navigation, I think blockbuster users really benefit from the submenu system of categorizing data, and if fact Blockbuster even allows them to refine the information they are looking for through the use of secondary submenu systems allowing users to really drill down in to what they are looking for to learn more on. I do not think that having more than one navigation bar on a web page is not confusing for the user. For example if you have a navigation bar at the top of your page and at the bottom will allow users to move around the website easier because they can utilize the navigation closest to where their cursor is on the page. In regards to designers forcing all the navigation in to one navigation bar, I think it would be hard for the user to fully understand what is going on based on the size and complexity of the site they are dealing with. For example Blockbuster has a ton of content that could not easily be put in to one navigation bar. From my experience with both Facebook and Blockbuster, they both do a good job with cross browser compatibility. I have had no issues with either site in IE, Firefox, Chrome, and Safari over the years. In addition, I do not believe that either Facebook or Blockbuster require any additional plug-in to utilize their navigation bars.

  • Task Scheduler Cannot Apply My Changes - Adding a User with Permissions

    - by Aaron
    I can log in to the server using a domain account without administrator privileges and create a task in the Task Scheduler. I am allowed to do an initial save of the task but unable to modify it with the same user account. When changes are complete, a message box prompts for the user password (same domain user I logged in with), then fails with the following message. Task Scheduler cannot apply your changes. The user account is unknown, the password is incorrect, or the account does not have permission to modify the task. When I check Log on as Batch Job Properties (found this from the Help documentation): This policy is accessible by opening the Control Panel, Administrative Tools, and then Local Security Policy. In the Local Security Policy window, click Local Policy, User Rights Assignment, and then Logon as batch job. Everything is grayed out, so I can't add a user. How can I add a user?

  • Problem posting multipart form data using Apache with mod_proxy to a mongrel instance

    - by Ryan E
    I am attempting to simulate my site's production environment as closely as I can on my local machine. This is a rails site that uses Apache w/ mod_proxy to forward requests to a mongrel cluster. On my Mac OSX Leopard machine, I have the default install of apache running and have configured a vhost to use mod_proxy to to forward requests to a local running mongrel instance on port 3000. <Proxy balancer://mongrel_cluster-development> BalancerMember http://127.0.0.1:3000 </Proxy> For the most part, this is working fine. I can browse my development site using the ServerName of the vhost I configured and can confirm that requests are being properly forwarded to the mongrel instance. However, there is a page on the site that has a multipart form that is used to upload an image to the server. When I post this form, there is a delay of about 5 minutes and the browser ultimately returns a Bad Request Your browser sent a request that this server could not understand. In the error log for my vhost: [Tue Sep 22 09:47:57 2009] [error] (70007)The timeout specified has expired: proxy: prefetch request body failed to 127.0.0.1:3000 (127.0.0.1) from ::1 () This same form works fine if I browse directly to the mongrel instance (http://127.0.0.1:3000). Anybody have any idea what the problem might be and how to fix it? If there is any important information that I neglected to include, post a comment, and I can add to this question. Note: Upon further investigation, this appears to be a problem specific to Safari. The form works fine in Firefox.

  • Any screen capture software that captures webcam, microphone inputs too ?

    - by mohanr
    I am going to conduct a user study. Apart from capturing the screen while the user is interacting with the system, I also want to capture the video/audio of the user. Is there any software that in addition to capturing the screen also overlays it with the webcam/microphone inputs. The goal is to capture the complete experience of the user: key/mouse interactions with the system along with their facial/vocal responses. I know that I can maybe run a screen-capture software and also run a software for capturing webcam audio/video alongside and try to sync/overlay both these streams with timestamps. But I am going to be dealing with probably several hundred hours of data. So I am looking for a tool that can streamline the process for me amap and help me keep my sanity at end of the process. Thanks,

  • SQL Server instance shuts down

    - by user42119
    I'm currently developing a new ASP.NET project hosted on a Windows Server 2008 RC2 with an SQL Server 2008 Express database. I have three SQL Server instances (for different purposes) running which currently all contain a single database. For apparently no reason, these instances tend to shut down after some days. There might be low or no traffic to these instances, because there might be some days in a row, where I can't develop. It now occurred several times, that one or two of these three instances just shut down, so that I can't access the database, without manually starting the instance. I can't seem to find a event log entry for the shutdown, which is most likely because I just enabled logging (why is the default setting off?). So the questions are: * Why does an SQL Server instance shut down? (Is there such a thing as a "Shut down instance after 3 days of inactivity"? * How can I achieve that the instances are running 24/7? Edit: I solved this problem by writing my own application that checks for the status of the SQL Server services. My program will start via a batch file, that gets called by the Windows Task Scheduler every 5 minutes.

  • VSFTP Users and Directories

    - by Mathew
    I'm stuck. I've been working all day on trying to figure out what I'm doing wrong and I've hit wall after wall. What I'm trying to do: Setup FTP in such a way that certain users have access only to their directory, but higher level users have access to all directories. What I've Googled so far: I started with this, but that didn't do what I needed it to. I then used this, but once I created one user, it wouldn't let me create another one. Finally, I decided to follow this, but it wouldn't let me even create one user. I'm using Ubuntu 10. I can login to ftp as a root user and it takes me to the home directory. If I try to login using the user I created in the tutorial it says: Status: Connection established, waiting for welcome message... Response: 220 (vsFTPd 2.2.2) Command: USER mathew Response: 331 Please specify the password. Command: PASS **** Response: 530 Login incorrect.

  • django-admin formfield_for_* change default value per/depending on instance

  • User and group permissions in access.conf

    - by Maddie
    How do I configure access.conf so that the following rule is applied? : Allow the user dia to connect from 192.152.100. Deny the user sim to connect from 192.152.100. Particularity : both the users dia (uid = 8389753) and sim (uid = 500) belong to the group sim (gid = 500) Yes, the user and group sim have the same name and the same id. With the follwing syntax, - : sim : 192.152.100. the user sim is denied, as well as dia (because dia belongs to the group sim). access.conf considers sim as being both the user and group. How do I specify that I want to deny the user sim, but at the same time allow the user dia ?

  • best way to store 1:1 user relationships in relational database

    - by aharon
    What is the best way to store user relationships, e.g. friendships, that must be bidirectional (you're my friend, thus I'm your friend) in a rel. database, e.g. MYSql? I can think of two ways: Everytime a user friends another user, I'd add two rows to a database, row A consisting of the user id of the innitiating user followed by the UID of the accepting user in the next column. Row B would be the reverse. You'd only add one row, UID(initiating user) followed by UID(accepting user); and then just search through both columns when trying to figure out whether user 1 is a friend of user 2. Surely there is something better?

    - by aviavi
    hey i have iphone application that using facebook connect. users login to the iphone application using facebook connect. and then i receive their sessionKey back to my server, and i am using the sesssionkey to post actions to users wall. the iphone application keeps the user logged in allways. which means that every times the user will open the application, he will not need to make login again. the problem is that, when the user change his facebook password the user sessionKey also changes. and when the user enter to my iphone applicaiton, the user is shown as loggedin, and then i recieve to my server the user old sessionkey, and when i try to post to the user wall facebook tells me that the session is inavlid. it is ok because the user change his password and the session changes too. my question is how can i check in the iphone if the session key has changed ? and if it changes to promote the user to make login again.

  • Naming multi-instance performance counters in .NET

    - by Roger Lipscombe
    Most multiple instance performance counters in Windows seem to automatically(?) have a #n on the end if there's more than one instance with the same name. For example: if, in Perfmon, you look under the Process category, you'll see: ... dwm explorer explorer#1 ... I have two explorer.exe processes, so the second counter has #1 appended to its name. When I attempt to do this in a .NET application: I can create the category, and register the instance (using the PerformanceCounterCategory.Create that takes a CounterCreationDataCollection). I can open the counter for write and write to it. When I open the counter a second time, it opens the same counter. This means that I have two applications fighting over the counters. The documentation for PerformanceCounter.InstanceName states that # is not allowed in the name. So: how do I have multiple-instance performance counters that are actually multiple instance? And where the second (and subsequent) instances get #n appended to the name? That is: I know that I can put the process ID (e.g.) on the instance name. This works, but has the unfortunate side effect that restarting the process results in a new PID, and Perfmon continues monitoring the old counter.

I have used https://graph.facebook.com/oauth/access_token?client_id=YOUR_APP_ID&client_secret=YOUR_APP_SECRET&grant_type=client_credentials and get the access token which is something like this access_token=454345994651138|bAMGfuW-ueNXGCahley7ga125HN and then https://graph.facebook.com/100005939123542/feed?access_token=454345994651138|bAMGfuW-ueNXGCahley7ga125HN It gives me general information such as user's likes, name, id, current city... but NOT user's wall posts. I've learned that there are three types of access token, which is App Token, User Token, and Page Token. In order to get user/feed by using graphAPI, I need to request to get User Token, but there's NO information in the lousy Facebook Doc! (Which frustrated me the most!) In order to generate the user access token, we need to set some permission, generate the access token, and GET the user's wall feed, which is in JSON format. My question is : How do I get the User Access Token in order to get user wall post in iOS Xcode?

    - by thatisvaliant
    i installed the latest epson software on my user's computer. everything works fine from the admin account (printing / scanning). yet, when i go to user's account (the standard user mode account the company employee uses on there machine) and launch the epson scan software or scan settings software it times out and puts up a dialog box asking me if i want to use the trouble assistant. my question is why would this all work in the admin account yet not work in the user mode account? any help is greatly appreciated.

  • NginX : Route user request to backend

    - by xperator
    The goal is to have NginX webserver act as a very basic & simple load balancer/fail-over. But instead of fetching static files from backend and serving it to user, I just want to route/redirect user request to one of the back end servers. upstream backend { server server1.example.com:80; server server2.example.com:80; server server3.example.com:80; } location / { proxy_pass http://backend; } Instead of : User request (example.com/test.file) NginX LB Backend NginX LB User I want to have : User request (example.com/test.file) NginX LB Backend User Is this even possible with NginX ? If not then How can I achieve this goal. UPDATE 1: Is there a way to use rewrite directive with backend upstream ? UPDATE 2: It's not really necessary to use NginX. I just want to have a direct reply from backend to user.

  • How to create an alias for a named SQL Server instance

    - by Svish
    On my developer computer I have an SQL Server instance named *developer_2005*. In the resource setting files of a C# application we are creating, the instance name is set to foobar (not really, but just as an example). So when I run the application (in debug or realease) it tries to connect to an SQL Server on localhost, named foobar. I am wondering if it is possible to create an alias or something like that, so that the application actually finds an SQL Server on localhost named foobar, but it is actually connecting to the instance named *developer_2005*. The connection string in the config file of the application is Data Source=localhost\foobar;Initial Catalog=barfoo;Integrated Security=True with provider name System.Data.SqlClient. If I change localhost\foobar to *localhost\developer_2005* then the application can connect like it should. How can I create an alias so that I won't have to change the string in the file? I tried, in SQL Server Management Studio, to create a Server Registration with registered server name "localhost\developer", but this didn't seem to do any good. Not even sure what that really did... But then I discovered SQL Server Configuration Manager\SQL Native Client COnfiguration\Aliases. And I kind of assume this is where the solution lies. But I can't quite figure out how to add a new one... When creating a new one, I have to provide Alias Name, Port No, Protocol and Server, and I don't really have a clue what to put in either of them.

  • Doubt about instance creation by using Spring framework ???

    - by Arthur Ronald F D Garcia
    Here goes a command object which needs to be populated from a Spring form public class Person { private String name; private Integer age; /** * on-demand initialized */ private Address address; // getter's and setter's } And Address public class Address { private String street; // getter's and setter's } Now suppose the following MultiActionController @Component public class PersonController extends MultiActionController { @Autowired @Qualifier("personRepository") private Repository<Person, Integer> personRepository; /** * mapped To /person/add */ public ModelAndView add(HttpServletRequest request, HttpServletResponse response, Person person) throws Exception { personRepository.add(person); return new ModelAndView("redirect:/home.htm"); } } Because Address attribute of Person needs to be initialized on-demand, i need to override newCommandObject to create an instance of Person to initiaze address property. Otherwise, i will get NullPointerException @Component public class PersonController extends MultiActionController { /** * code as shown above */ @Override public Object newCommandObject(Class clazz) thorws Exception { if(clazz.isAssignableFrom(Person.class)) { Person person = new Person(); person.setAddress(new Address()); return person; } } } Ok, Expert Spring MVC and Web Flow says Options for alternate object creation include pulling an instance from a BeanFactory or using method injection to transparently return a new instance. First option pulling an instance from a BeanFactory can be written as @Override public Object newCommandObject(Class clazz) thorws Exception { /** * Will retrieve a prototype instance from ApplicationContext whose name matchs its clazz.getSimpleName() */ getApplicationContext().getBean(clazz.getSimpleName()); } But what does he want to say by using method injection to transparently return a new instance ??? Can you show how i implement what he said ??? ATT: I know this funcionality can be filled by a SimpleFormController instead of MultiActionController. But it is shown just as an example, nothing else
