• GWT + XML documents with namespaces

  - by chris_l

  I'd like to get a quick overview of available solutions (libraries, ...) that allow me to work with XML documents with namespaces on a DOM level - in GWT's client side. Additionally, I'm looking for an XPath solution that can work on that DOM (even if it requires writing my own XPath Navigator). XML parsing and serialization isn't necessary on the client - this can be done on the server.

• VS2010 asp.net: executing parameter less stored proc to update record

  - by dotnet-practitioner

  I would like to execute a stored proc that simply updates a record. At this point I would like to keep it parameter less. But in future, I will be adding parameters to the stored proc. Can I simply do it via SQLDataSource? It will save me writing few lines of code to execute stored proc in a traditional ado.net. If its possible, could you please supply me with a sample code? Thanks

• We want to setup low cost private cloud [closed]

  - by Virtual Jasper

  We are a small company with very limit funds. In order to improve our server reliability, we are studying to migrate to CLOUD.

So we looking at Linux side, we look at Ubuntu and OpenStack. What is the different between Ubuntu and OpenStack solutions? Is it both free on software license? and only to pay the technical support.

• Controlling access to my API using SSH public key (not SSL)

  - by tharrison

  I have the challenge of implementing an API to be consumed by relatively non-technical clients -- pasting some sample code into their WordPress or homegrown PHP site is probably as much as we can ask. Asking them to install SSL on their servers ain't happening. So I am seeking a simple yet secure way to authenticate API clients. OAuth is the obvious solution, but I don't think it passes the "simple" test. Adding a client id and hashed secret as a parameter to the requests is closer -- it's not hard to do md5($secret . $client_id) or whatever the php would be. It seems to me that if client requests could use the same approach as SSH public keys (client gives us a key from their server(s) there should be some existing magic to make all of the subsequent transactions transparently work just as regular HTTP API requests. I am still working this out (obviously :-), so if I am being an idiot, it would be nice to know why. Thanks!

• DirectX capabilities on different graphics cards

  - by user9876

  I'm writing a Direct3D application, using DirectX 9. Although it works on my PC, I need to make it work on a wide range of systems. I need to know what capabilities I can expect to see on other systems. Is there a list of the DirectX capabilities that graphics cards support? I've found one site, which I'll post as an answer, but it's a bit out of date.

  - by Kip

  What is a good non-programming question to ask a candidate during a job interview? I'll post my two favorites below, but I'd like to hear others. Clarification: By "non-programming," I mean you are not asking them to solve a problem by writing or describing code.

  I am writing a GAE application and I would like to have an input box with google auto-suggest. Specifically, when a user types "Shawshank" I would like to see google's suggestions in my drop down. Can someone tell me what are the different ways of doing this? I understand I may have to use some javascript libraries so any code samples etc will help immensely. (Pure javascript/jquery kinda solutions will be more preferable)

  Hello All, I am writing a little install script for some software. All it does is unpack a target tar, and then i want to permanently set some environment variables - principally the location of the unpacked libs and updating $PATH. Do I need to programmatically edit the .bashrc file, adding the appropriate entries to the end for example, or is there another way? What's standard practice? Thanks

  Hi I writing a WCF Service that need transfer large files, so i using streaming, but from the other hand i need to do username specific initializations. The problem is that getting the username and perform initialization every time is very expensive.

• How do I convert filenames from unicode to ascii

  - by zedwarth

  I have a bunch of music files on a NTFS partition mounted on linux that have filenames with unicode characters. I'm having trouble writing a script to rename the files so that all of the file names use only ASCII characters. I think that using the iconv command should work, but I'm having trouble escaping the characters for the mv command.

• How do I conditionally redirect the output of a command to /dev/null?

  - by Lawrence Johnston

  I have a script. I would like to give this script a quiet mode and a verbose mode. This is the equivalent of: if $verbose then redirect="> /dev/null" fi echo "Verbose mode enabled" $redirect # This doesn't work because the redirect isn't evaluated. I'd really like a better way of doing this than writing if-elses for every statement affected. eval could work, but has obvious side effects on other variables.

• How can I specify the name of a mounted drive in Windows when mounting programmatically?

  - by Alex Feinman

  I am writing a perl routine that mounts specific drives at startup. However, when the drives are mounted, they appear in "My Computer" with odd names like "dir$ at 'machinename' (H:)". Is there a way in perl or C to specify this string (or just the 'dir$' part?) at mount-time?

• Undo implementation - DOM manipulations

  - by sonofdelphi

  Is there a library that can be used for implementing undo/redo functionality for DOM element manipulations in JavaScript? I'm writing an app that moves around DOM elements, enables editing and deletion of those elements. There are event-handlers and other objects associated with each element operated upon. Not sure whether I need to roll my own implementation of the Command pattern for this. Surely, there must be something available? If not, suggestions and pointers would be a great help.

• Is it possible to put an 8000 series socket-F Opteron into a dual-socket motherboard?

  - by René Kåbis

  Exactly what it says on the Tin. I have a dual-socket, socket-F motherboard in which I am looking to put two high-end quad-core Opterons, but the 2000 series are nearly double the price of the 8000 series on eBay. Can I just drop in a pair of 8000 series processors and be done with it, or are there processor-critical motherboard features that would be present on a quad(+)-socket motherboard that don’t exist on a dual-socket motherboard? Please elaborate or link to resources that can explain this further, as I am not adverse to research (and I am interested in the technical issues involved) I am probably using the wrong search terms, as Google failed to return anything within the first few dozen results.

• C++ operator[ ] on integer litteral

  - by gregseth

  I found this piece of code: char a = 1["ABC"]; A few quick test led me to the fact it was the same than writing: char a = "ABC"[1]; Which seems far more logical to me. So my questions: Why is this notation valid? Is there any reason to write something that way?

• Driver for Sony Vaio Alps Touchpad for Ubuntu 11 [closed]

  - by Shimul Bhowmik

  I have vaio E-series laptop. Recently I installed ubuntu 11 on it. My touchpad seems to be working except the fact that in settings no touchpad is shown. As a result, I can't configure it for edge-scrolling or deactivating it while typing. I have already tried configuring grub (actually it was already configured). I have even installed softwares like 'psmouse-alps 0.11' but of no use. Technical staff of sony blatantly replied that they only provide support in windows..blah... Now, I am really worried if my touchpad will ever work properly or not ... Please help...

• Determine how an application is closed

  - by Mike_G

  I am trying to determine if my application is closed through clicking the "X" on the windows form, or if they clicked an "Exit" button I have on it. Right now I am using StackTrace.GetFrame(someIndex) to determine how, but i am looking for a more definitive way since it looks like these frame orders arent guaranteed. Is there a better way to make the distinction? This is a .NET 3.5 WinForm, and Im writing in C#.

• Is the Sleep operation no longer used in VBscript?

  - by Cheesus Toast

  The "Sleep" command as stated in many places over the internet (including here on this forum) DOES NOT WORK. Is it now an obsolete command? I am writing the VBScript code like this: sub button1_onclick() Wscript.Sleep 1000 div1.innerHTML = textbox1.value end sub It should wait 1 second and then execute that simple command. This is an utterly simple statement but it does not work. Plain and simple. It comes up with an error every time saying: Object Required: 'Wscript'
