• Is it poor form to use class attributes with no corresponding css rule?

  - by CRice

  For example if I wanted to select some elements with a certain class using jQuery, and for that reason only, is it always expected that those classes SHOULD be defined in the css?. <div class="xyz"> something </div> <div class="xyz"> something else </div> //with example jQuery $(".xyz").hide(); //is it wrong no element 'xyz' is defined in css?

• Android - Declarative vs Programmatic UI

  - by Steve

  Has anyone seen or compiled benchmarks comparing declarative (XML) versus programmatically created UI's in Android?

Have you ever switched (or considered) changing your UI from declarative to programmatic for any reason?

• Why use singleton instead of static class?

  - by Jouke van der Maas

  When would a singleton actually be easier or better than a static class? It seems to me creating a singleton is just extra effort that's not actually needed, but I'm sure there is a good reason. Otherwise, they wouldn't be used, obviously.

• Why was the SASS depreciated in favour of SCSS?

  Basically, why SCSS, instead of SASS? The shorthand of SASS was the main reason why I picked up SASS, I recently came back to it and realised that it is no longer in favour. Any reasons why?

• How does one go about writing a virtual MIDI interface?

  - by Alex

  I want to do some funky things with controlling MIDI streams, and I'd like to be able to pipe MIDI input into an application like Ableton or Reason. Presumably this involves some sort of driver level work? Ultimately I'd like to write my application in Python, so if there is some Python-based solution, I'd consider it. I'm perfectly fine with using C/C++, though, so that's not a problem.

• Is HTML considered a programming language?

  - by nihilist.myopenid.com

  I guess the question is self-explanatory, but I'm wondering whether HTML qualifies as a programming language (obviously the "L" stands for language). The reason for asking is more pragmatic—I'm putting together a resume and don't want to look like a fool for listing things like HTML and XML under languages, but can't figure out how to classify them.

• Can I concatenate multiple MySQL rows into one field?

  - by Dean

  Using MySQL, I can do something like select hobbies from peoples_hobbies where person_id = 5; and get: shopping fishing coding but instead I just want 1 row, 1 col: shopping, fishing, coding The reason is that I'm selecting multiple values from multiple tables, and after all the joins I've got a lot more rows than I'd like. I've looked for a function on MySQL Doc and it doesn't look like the CONCAT or CONCAT_WS functions accept result sets, so does anyone here know how to do this?

• Android - How to prevent the phone screen from turning on when volume or camera key is pressed?

  - by 2Real

  I have an activity that shows up when the phone screen goes to sleep/turns off ie turns black. For some reason, the phone turns on when the volume buttons or the camera buttons are pressed. By turns on, I mean the screen wakes up or comes back from the black screen state. I've tried using dispatchKeyEvent(KeyEvent event) and the buttons are disabled on the activity, but they still wake up the phone.

• Why wait should always be in synchronized block

  - by diy

  Hi gents, We all know that in order to invoke Object.wait() , this call must be placed in synchronized block,otherwise,IllegalMonitorStateException is thrown.But what's the reason for making this restriction?I know that wait() releases the monitor, but why do we need to explicitly acquire the monitor by making particular block synchronized and then release the monitor by calling wait() ? What is the potential damage if it was possible to invoke wait() outside synch block, retaining it's semantics - suspending the caller thread ? Thanks in advance

  Hi, We are using WiX to create a setup. The installation works fine, but during uninstallation an error says that the [FileName].msi is missing in C:\Windows\Installer and the setup starts rolling back. It is not reproduced in all the machines. It happens only in few machines. Could someone please give a solution to this ? What may be the reason that this happens only in 5 machines out of some 100 machines ? Thanks and Regards, Varun

• R language: open ssh connection

  - by marpo_it

  I am trying to open a remote shell via ssh to send commands from R. As long as I send commands, I need to get results and send new commands that depends on the output of the previous ones. For this reason I am looking for a solution to open a connection and manage it from within the R code until I have finished. I also need to open the connection with ssh key exchange (so without password authentication). Looking at CRAN I didn't find anything useful.
