• Which window manager do you use?

  - by Stephan202

  Combining "What is your default web browser?" and "What are the differences between Linux Window Managers", I ask you: which window manager do you use, and why? Myself I prefer a minimal window manager on the one hand (in the past I used Fluxbox), but on the other hand wish to go with the main stream, to ease finding (Googling) solutions in case of problems. Hence I stick with Gnome as it is shipped with Ubuntu. Why do you use the window manager which you use? I understand some reasons may be subjective, but please try to cite technical reasons where possible.

• How to solve my black screen at boot?

  - by Juanillo

  I've got a friend with a weird problem. When he starts his computer the screen is completely black until the computer is completely started. So the screen is black until it suddenly shows the Windows desktop. He said that this is happening since a technical service repaired his computer, but that repair is not now in warranty. Recently the computer stopped working, but as the screen is black he cannot access to BIOS or start in safe mode (by pressing F8). When he inserts the Windows Vista DVD the system doesn't boot from DVD (it mustn't be configured in this way in the BIOS). Maybe there´s a problem with the hardware (maybe the graphic card)? Can anyone explain a reason why the screen is black during start-up? Any idea of what to do with the computer to restore it?

• How can one extra rdf:about or rdf:ID properties from triples using SPARKQL?

  - by lennyks

  It seemed a trivial matter at the beginning but so far I had not managed to get unique identifier for a given resource using SPARKQL. What I mean is given and then some properties identifiying this resource in perfect world I want to first know how to retrieve an individual triple given some uri. I have tried naive approaches by writing statements in a WHERE clause such as ?x rdf:about ?y and ?x rdfs:about ?y. I hope I am being precise.

• how to time out an ant task

  - by Christopher Dancy

  Without writing a custom ant task is there a way to use a timeout on a regular ant target? To give some background info ... we are using the delete task to remove all contents of a given directory. Sometimes this directory is massive with lots of generated folders and files. We wanted to have that task say timeout after 5 minutes. I could not find anything online anywhere ... any ideas?

Can/does anyone want to prove it?

• Several ifstream vs. ifstream + constant seeking

  - by SpyBot

  I'm writing an external merge sort. It works like that: read k chunks from big file, sort them in memory, perform k-way merge, done. So I need to sequentially read from different portions of the file during the k-way merge phase. What's the best way to do that: several ifstreams or one ifstream and seeking? Also, is there a library for easy async IO?

• Learning the Introspection API (used by FxCop)

  - by Anand Patel

  Microsoft's FxCop tool uses the introspection API. This introspection API could be used to develop new code analysis tools. But the introspection api is not documented well. Additionally, I was not able to figure out any blogs which explains this API in breadth and depth of it. The knowledge gained by understanding the API can also be used for writing custom FxCop rules. Does anybody knows about any blog or resources which explains the same?

• First version of Linux

  - by dole doug

  Hi there I've heard many times that Linus Torvalds is a genius when it comes to writing good code. I also wish to write good code and I'd like to see how the first version of Linux was written. Does anyone know where I can find the first version of Linux? I'm looking for the first version (not 1.0) because I think it will be smaller and easier to understand. Many thanks.

• Ruby / rubyzip alternative capable of handling rar/tar/zip/7z?

  - by Nick Gorbikoff

  I was wondering if anyone knows of rubyzip alternatives for Ruby, that can handle various formats in particular zip / rar / 7z? I know of libarchive, but it's not complete for my purposes ( it's a good gem thou). (To clarify, libarchive - won't work for me - cause I need to be able to run in on Windows. ( Yeah I know sucks to be me)) Right now I end up running system commands to the os, but I'd like something OS independent, and capable of handling those formats - reading and writing. Thank you

• Intermediate SSL Certificates on Azure Websites

  - by amhed

  I have successfully configured an Extended-Validation Certificate on an Azure Website following this article: http://www.windowsazure.com/en-us/documentation/articles/web-sites-configure-ssl-certificate/ The main (non-technical) stakeholder of the web application went through great lengths to validate that our site is secure. He went to this site to check the validity of our SSL: http://www.whynopadlock.com/ The site throw the following error: `SSL verification issue (Possibly mis-matched URL or bad intermediate cert.). Details: ERROR: no certificate subject alternative name matches`` The certificate is installed using IP Based SSL instead of SNI. This is done this way because some site visitors still use Internet Explorer 8 on Windows XP, which has no support for SNI and throws a security warning. Is my certificate correclty installed? I received three .CRT files from my SSL provider: PrimaryIntermediate.crt SecondaryIntermediate.crt EndCertificate.crt This is how I exported our certificate as a .PFX file to Azure: openssl pkcs12 -export -out myserver.pfx -inkey myserver.key -in myserver.crt

• prohibiting instantiation as a temporary object (C++)

  - by SuperElectric

  I like using sentry classes in c++, but I seem to have a mental affliction that results in repeatedly writing bugs like the following: { MySentryClass(arg); // ... other code } Needless to say, this fails because the sentry dies immediately after creation, rather than at the end of the scope, as intended. Is there some way to prevent MySentryClass from being instantiated as a temporary, so that the above code either fails to compile, or at least aborts with an error message at runtime?
