• MongoDB Norm query nested objects

  - by Howard

  Does anyone have a sample of how to query for nested/inner objects in MongoDB using NORM (C#)? For example, if a typical document in a collection looks like Order/OrderItems, how can I look up a specific OrderItem by OrderItem.Quantity 10.

• How to ignore query parameters in web cache?

  - by eduardocereto

  Google Analytics use some query parameters to identify campaigns and to do cookie control. This is all handled by javascript code. Take a look at the following example: http://www.example.com/?utm_source=newsletter&utm_medium=email&utm_ter m=October%2B2008&utm_campaign=promotion This will set cookies via JavaScript with the right campaign origin. This query parameters can have multiple and sometimes random values. Since they are used as cache hash keys the cache performance is heavily degraded in some scenarios. I suppose there's a not so hard configuration on cache servers to just ignore all query parameters or specific query parameters. Am I right? Does anyone know how hard is it in popular web cache solutions, to create ? I'm not interested in a specific web cache solution. It would be great to hear about the one you use.

• Is it possible to serve up a resource as both JSON and Aspx with OpenRasta?

  - by Jeffrey Cameron

  (I'm also asking this on the OpenRasta google group) Hey all, I've been using OpenRasta to convert an old web application we have into something RESTful. IS it possible to serve up a resource (or specifically a list of resources) as both .aspx and JSON? I have tried this but no matter what I try I keep getting the .aspx back ... any ideas? Here's a sample configuration: ResourceSpace.Has.ResourcesOfType<List<Valueset>>() .AtUri("/valuesets") .HandledBy<ValuesetHandler>() .AsJsonDataContract() .And.AsXmlDataContract() .And.RenderedByAspx("~/Views/VauesetView.aspx")

• Facebook verify account

  - by dman

  I can't login to Facebook because they think someone tried to hack my account. To verify it's really me they present me with photos that my friends have been tagged in and ask me to give them the correct names of who is tagged in the photos. Now because alot of my friends think it's funny to tag themselves in random photos of others, or tag themselves as objects in photos, I can't successfully get all 10 correct. I also have alot of friends of friends that have added me that I don't know closely enough to identify the back of their head in a distant blurry photo. Facebook only allows one attempt per hour to try this. How am I supposed to restore my account when they have such a stupid method to prove identity?

• Entering IT field with only hobby experience?

  - by EA Bisson

  I can build computers, install servers, network mac, linux, and windows, build servers, do support etc. I do all of this at home/for friends/for hobbies.

I am the IT go to gal at every position usually because I know more than the IT people and have better people skills. My job history is random: office admin, hair braider, disney ride operator, camp counselor etc. I found a job I want its a entry level specialist (server) position. What do I put on a resume?

• VS2008 C++ MFC Access Violation ONLY when stepping through debug mode

  - by HotOil

  Hi. This is crazy. It started happening in my main project, so I created a tiny sample brand-new project to reproduce it in and sure enough.. It does NOT happen in a sample project I created that is only a Win32 console app. I'm running this on Win7x64, if that matters. VS2008 SP1. Here goes. I create a small dialog app with a button. Put a breakpoint in the handler function for that button. The button handler function looks like this: void CTestProjectDlg::OnBnClickedButton1() { int i=2; m_csHello.Format(_T("Hello World!")); << breakpoint here UpdateData(FALSE); } Click the button, hit the breakpoint. F10 to step, and boom: "First-chance exception at 0x0398f77b in TestProject.exe: 0xC0000005: Access violation." It gives me the option to Break or Continue. If I Continue, it just hits it again, only not "First Chance". Yes I have that exception checked in the Debug-Exceptions dlg. If I Break, the call stack just shows me the line where the breakpoint is. If I F10 again.. I get the exception again, only now the callstack shows me in the _AfxDispatchCmdMsg() function, and my original OnBnClickedButton1() is not in the callstack anymore. It doesn't matter where I put the breakpoint. If, instead of F10, I just continue with F5, it works normally. Now.. if I build a Release version and run in debugging mode: I hit the breakpoint, and all the pointers, variable values look normal. F10, and these turn to garbage. The this pointer is now zero. The m_csHello is now However, in Release mode, an exception is not caught, and it all runs fine. The "hello World string gets displayed in the dialog box as it should. I have put in an inquiry to see if some patch was installed on my box by the IT dept in the last day or two. This wasn't happening 2 days ago. What do you think? Is VS2008 corrupted? Thanks.

• How to make and use first object in Objective C to store sender tag

  - by dbonneville

  I started with a sample program that simply sets up a UIView with some buttons on it. Works great. I want to access the sender tag from each button and save it. My first thought was to save it to a global variable but I couldn't get it to work right. I thought the best way would be to create an object with one property and synthesize it so I can get or set it as needed. First, I created GlobalGem.h: #import <Foundation/Foundation.h> @interface GlobalGem : NSObject { int gemTag; } @property int gemTag; -(void) print; @end Then I created GlobalGem.m: #import "GlobalGem.h" @implementation GlobalGem @synthesize gemTag; -(void) print { NSLog(@"gemTag value is %i", gemTag); } @end The sample code I worked from doesn't do anything I can see in "main" where the program initializes. They just have their methods and are set up to handle IBOutlet actions. I want to use this object in the IBOutlet methods. But I don't know where to create the object. In the viewDidLoad, I tried this: GlobalGem *aGem = [[GlobalGem alloc]init]; [aGem print]; I added reference to the .h file of course. The print method works. In the nslog I get "gemTag value is 0". But now I want to use the instance aGem in some of the IBOutlet actions. For instance, if I put this same method in one of the outlet actions like this: - (IBAction)touchButton:(id)sender { [aGem print]; } ...I get a build error saying that "aGem is undeclared". Yes, I'm new to objective c and am very confused. Is the instance I created, aGem, in the viewDidLoad not accessible outside of that method? How would I create an instance of a Class that I can store a variable value that any of the IBOutlet methods can access? All the buttons need to be able to store their sender tag in the instance aGem and I'm stuck. As I mentioned earlier, I was able to write the sender tag to a global variable I declared in the UIView .h file that came with the program, but I ran into issues using it. Where am I off?

• NSString copy not copying?

  - by Scotty Allen

  NSString *myString = @"sample string"; NSString *newString = [NSString stringWithString: myString]; If I set a breakpoint after these two lines, the pointer for myString is the same as the pointer for newString. WTF? Isn't NSString copy supposed to return a pointer to a new object? Or am I missing something fundamental about how copy is supposed to work?

• Trackpad and battery on stop working at same time

  - by Alex Krycek

  Gateway E-475M G Windows 7 Professional SP1 Synaptics TouchPad 15.2.20.0 Microsoft ACPI-Compliant Control Method Battery 6.1.7600.16385 It seems that when my battery stops working correctly, my touchpad will also act erratically. Specifically, the computer will charge for a few seconds, then stop charging for another few seconds. This will continue for some time. But if I close the lid, the charging LED will stay lit. As for the touchpad, it'll click or highlight things at random when I can get it to move. As a test, I stopped charging my computer. Now it seems my touchpad is working fine. I've tried to reinstall both the battery and touchpad drivers. I've also started the computer in safe mode, but that didn't help either. Edit: I've now tried booting my computer with an Ubuntu live cd, and the charging problem persists. So, it now seems my computer can only charge continuously as long as it's turned off or sleeping.

• If NSString stringWithContentsOfFile is deprecated, what is its replacement?

  - by mobibob

  I have some sample code from Tuaw which is probably 3 releases old ;) The compiler is issuing a warning that the method is deprecated, but I do not see that mentioned in the SDK docs. If it is deprecated, there must be an alternative approach or replacement method. Does anyone know what the replacement is for this method?

• Windows 2008 R2 server cannot access shares on other servers

  - by Rob

  I have a problem on my new 2008 R2 64-bit server. Essentially the server sometimes refuses to access shares on other server. in the format \\servernam\sharename sometime it works and then for a few hours it doesn't and then at randon it comes back online. This is a local AD network and have even put in a new gigabit switch between all server. All the old 2003 servers work fine so I know DNS and WINS is all ok. I get error 1006 in eventlog saying that my R2 server can't contact the domain controller when it clearly can. Just to add to the config, it is running on a Dell PowerEdge R410, Vmware Esxi 4.0 and R2 is configured as a terminal server. I can always view shares with FQDN This morning net view \\ did not work but net view \\ did. Very random and very frustrating. any ideas? thanks

• Django | twilio to send SMS

  - by MMRUser

  I'm using twilio as for a mobile verification mechanism, I have no prior experience in using twilio but looking at the sample PHP code I used this one in my code but apparently it's giving me an 400 Bad request HTTP error. Here's the code: d = { 'TO' : '*** *** ****', 'FROM' : '415-555-1212', 'BODY' : 'Hello user, please verify your device using this code %s' % verNumber } try: print account.request('/%s/Accounts/%s/SMS/Messages' % \ (API_VERSION, ACCOUNT_SID), 'POST', d) except Exception, e: return HttpResponse('Error %s' % e) verNumber is randomly generated and the receiver's number is validated in twilio. Thanks.

• Ubuntu: Take actions when system temperature gets too high

  - by Josh

  One of the CPU fans on my Compaq Presario laptop running Ubuntu 9.10 seems to have bit the dust. The fan is deep within the case and I intend to replace the laptop in the next 6 months so it's not worth replacing it. I have the laptop on a cooling pad and most of the time the system is fine, CPU temps around 90°-110°F. Occasionally, however, I'm seeing random lockups which I believe is due to the system overheating. How can I configure the system to: Lower the CPU speed when the temperature reaches a certain level? (I.E. 110°F) Shutdown the system when the tempature reaches a critical level? (And what would that be? 130°?)

• NTRUEncrypt source code?

  - by applesoranges

  I asked this before, but didn't get any responses. Can anybody point me to C or Java code (or anything else) that does NTRU encryption? Several people who were implementing the algorithm have posted on this site, so maybe they could help? I also noticed that quite a number of NTRU implementations have been written at universities, so it would seem strange that sources, or at least sample code, are so hard to come by. Thanks!

• Computer is totally crashed

  - by Napster

  my computer kept restarting on its own at random times varying from 1 minutes, to 20 minutes(then goind in a constant restart loop every ~10 seconds). I had to turn it off and wait minutes or hours before attempting to restarting to go further in the boot process. Now, it just does not turn on. I posted this before: Computer crashes every 2 to 10 minutes but I did not have the time to check the temperature. I don't want to pay to get it checked up, but I want to know what is wrong. Is the processor fried? Thank you
