• What's the problem with Scala's XML literals?

  - by Oak

  In this post, Martin (the language's head honcho) writes: [XML literals] Seemed a great idea at the time, now it sticks out like a sore thumb. I believe with the new string interpolation scheme we will be able to put all of XML processing in the libraries, which should be a big win. Being interested in language design myself, I'm wondering: Why does he write that it was a mistake to incorporate XML literals into the language? What is the controversy regarding this feature?

• Text limit on analytics event code

  - by Theo G

  I am just about to add the event code a button that downloads the pdf.

• How do I get this Mac OS X exposé behavior?

  - by quangtruong1985

  In Mac os x, I can move all windows to the nearest corner by hitting F11 key. I'm just wondering if there is a compiz plugin works like that. I know that there is Scale plugin already. But all that I want is something like this. You'll see, press a key and all windows fly off to nearest corner so I can drag/drop file or do something else on my desktop, then press the key again and all windows fly back.

• C# Algorithms for * Operator

  - by Harsha

  I was reading up on Algorithms and came across the Karatsuba multiplication algorithm and a little wiki-ing led to the Schonhage-Strassen and Furer algorithms for multiplication. I was wondering what algorithms are used on the * operator in C#? While multiplying a pair of integers or doubles, does it use a combination of algorithms with some kind of strategy based on the size of the numbers? How could I find out the implementation details for C#?

• A good resource to get the most out of Google Analytics

  - by glinch

  I was wondering if any one could offer me some advice as to the best resources out there (ideally books) on google analytics. I have a basic understanding but have a lot of room for improvement. The following book "Advanced Web Metrics with Google Analytics" by Brian Clifton, appears to be a good starting but but is already quite dated, even though published in march 2010. Any advice would be greatly appreciated.

• Best approach to designing multi-client applications

  - by Tomh

  Hi, I was wondering how you guys start out if you need to design a multi-client project where multiple clients can interact with a server. In specific how do you go about dealing with different states and message handling, how do you start designing and considering all these cases? For example a video webchat application where it is possible that you call another client, while that client is already in a call, or is stuck in a modal dialog such that the calling dialog does not come through.

• Sprite Animation Toolkits for iPhone

  - by Mike Eggleston

  Does anyone know of any good (and preferably free) Sprite Animation Toolkits/Libraries for iOS development? This library should be able to handle the collision detection and the movement of the sprites. Back in the 90's there was a Pascal library called Sprite Animation Toolkit by Ingemar Ragnemalm that handled a lot of the heft to create animations and the such. I am just wondering if there is anything like that in the iOS world?

• How to identify doc, ppt, xls files

  - by Shelby. S

  So I was wondering how would you differentiate ppt, xls and doc files from each other in linux regardless of extensions. I tried 'file' but from the looks of it, all of MSOffice files are categorized under the same file type. Similarly I'm having trouble with docx, xlsx and pptx files, since they're essentially all zip files containing a bunch of xml. Thank you for your help! P.S. I also tried a python script importing the magic module, but no go.

• What should come first: testing or code review?

  - by Silver Light

  Hello! I'm quite new to programming design patterns and life cycles and I was wondering, what should come first, code review or testing, regarding that those are done by separate people? From the one side, why bother reviewing code if nobody checked if it even works? From the other, some errors can be found early, if you do the review before testing. Which approach is recommended and why? Thank you!

• Use same dns server for all (future) connections

  - by kleofas

  I'm wondering if it is possible to specify, that all connections (even future, like when using wifi at some other place (=different SSID)) will be using pre-defined DNS server When I have some (concrete) connections, I could go to IPv4 settings, and specify DNS server there (however, in case of new connection I would have to do it (and not forget it)) This may be particularly useful for some safe/filtering dns (such as opendns's 208.67.222.123 & 208.67.220.123)

• Map format for 3d open world

  - by Pacha

  I am making an open world 3d platformer in Ogre3D, and I have no idea on what kind of 3d map file format I should use for it. I want to make low-polygon blocky-style objects. Probably rectangles and other geometrical figures that don't have circular edges. Some of those blocks will have properties, like climbable or they might move. I was wondering what would be the best thing to do to make the map (just one level, as it is open).
