  Hey Everyone, The installation for clearance seems very straight forward (http://wiki.github.com/thoughtbot/clearance/installation).

• How to secure an AJAX call from a facebook canvas application.

  - by user259349

  Reading this Ajax example, http://wiki.developers.facebook.com/index.php/FBJS/Examples/Ajax#Working_Example I found the following line. I'm not sure what to understand out of it, how do you "check the sig values per Platform spec"? "Note: For brevity's sake we are trusting $_POST['fb_sig_user'] without checking the full signature. This is unsafe as anyone could easily forge a user's action. Always be sure to either use the Facebook object which is supplied with the client libraries, or check the sig values per Platform spec"

• Where is the VM in LLVM?

  - by anon

  Note: marked as community wiki. Where is the Low Level Virtual Machine in LLVM? I see that we have llvm-g++ and c-lang, but to me, a LLVM is something almost like Valgrind of a simulator, where instructions are executed on it, and I can write programs to instrument the running code / interrupt when certain conditions happen / etc ... Where are the tools like this built on LLVM? Thanks!

• Adobe Flex 4.0 vs Silverlight 4.0

  - by Jason Towne

  While this not necessarily a technical question, I believe it will help a lot of developers (including myself!). With Silverlight 4.0 and Flex 4.0 both in beta, I thought I would put out an open question to the community and see what everyone likes and dislikes about each framework and why. I've worked with Flex in the past but have decided to take another look at Silverlight with the new version being released. Thoughts anyone? Edit: Made it a community wiki. :)

• Upload a Photo to Facebook with REST API and Ruby

  - by Michael Waxman

  It's much harder than you'd think: http://wiki.developers.facebook.com/index.php/Photos.upload The tricky part is how to create the MIME multi-part message in Rails, which Facebook requires. I'm also using a Ruby Facebook API gem (mini_fb) which signs my other requests, and in addition to having no idea how to set up the MIME multi-part, even if I did I'm not sure how to add in the required signature values with the gem. Please help!

• Which software do you use for SCRUM ?

  - by Rahul Soni

  I checked wikipedia, http://en.wikipedia.org/wiki/Scrum_(development) But I am still looking for some insight from the genius minds using SO. I installed Microsoft Project 2010, and was assuming that it would have some template/plugin that would support SCRUM. Unfortunately, I couldn't find one :-(

• Is there a web application equivalent of Hypercard?

  - by Gabriel Cuvillier

  Recently, I found an interesting Wiki/CMS/Database hybrid called Wagn, where the most important unit of information is the 'Card'. That terminology immediately made me think of Hypercard. As expected, there is some "Hypercard-ness" in that application. Do you know of other web applications/frameworks with that "Hypercard-ness" thing, or if its successor still must be invented? Note: I insist on web applications because I already know the desktop ones.

• Can I write for .Net 4 using VS2008?

  - by chillitom

  Can I write code against .Net 4 and its libraries using VS2008? If so how should I configure it? I realise that VS2008 will probably struggle with language changes such as the dynamic keyword but can I install the version 4 and target it anyway? My only real interest is in being able to use some of the new libraries, in particular I'm interested in the TPL (http://en.wikipedia.org/wiki/Parallel_Extensions)

• How do you embed XHTML into APT file when using Maven to generate a site?

  - by Clinton

  I am using maven to generate a website for a Java project, which uses APT "Almost Plain Text" as a wiki like markup. Maven takes this and turns it into XHTML. I already have a custom template/skin that I am using for the site, but the index page will have a couple of extra custom design elements that are beyond the capabilities of APT. So how can you add xhtml to the apt file so that it gets correctly embedded in the final output? Thanks.
