  - by Majid

  Many tutorials focus mainly (or exclusively) on 'how to do XYZ'. There are questions persuading pear SO user share good resources in that category.

You know, that very article, white paper, podcast, executive summary, ... that led you to a Aha! moment and you finally saw the woods not just the trees.

• Rails - good tool to create a scheduled background process which will regularly retrieve messages fr

  - by adam

  Background Job gets mentioned a lot but all the tutorials I've seen seem to indicate that its for queuing jobs which are created by some external event such as a user clicking "Send mail". But what about when you have code that needs to scheduled to run every 30 seconds to listen for new messages from twitter? Normally rake is recommended for set in stone schedules but it inst so efficient for frequent jobs as it has to to load the entire rails app each time. Can anyone recommend anything for this situation?

• django app with a generic name

  - by zaharpopov

  Django tutorials everywhere use constant-set application name all around - in urls file, in HTML templates, in views. But if I want to distribute an application and let the user sets it name (i.e. its URL postfix on http://server.com/appname) - how can I do? I must have some common name setting then in configuration, but how to work it for template files, etc?

• Setting processor to 32-bit mode

  - by dboarman-FissureStudios

  It seems that the following is a common method given in many tutorials on switching a processor from 16-bit to 32-bit: mov eax, cr0 ; set bit 0 in CR0-go to pmode or eax, 1 mov cr0, eax Why wouldn't I simply do the following: or cr0, 1 Is there something I'm missing? Possibly the only thing I can think of is that I cannot perform an operation like this on the cr0 register.

I tried Google, but didn't find anything helpful.

• Using the word "you" in an user manual

  - by yan bellavance

  I am writing a user manual and I have come to a discussion with a colleague. He says I cannot use the word "you" anywhere in the manual. Now I remember something about this at school but that was not for writing procedures. Also, doing some googling I observed that most tutorials where using it a lot. I would prefer using it but only if this is considered good practice. what do you think?

• Is it possible to call BlazeDS from Java?

  - by Stephane Grenier

  Basically I'm trying to proxy some webservices locally (for reasons I won't go into now) and then have a Java application call it. I'm looking at BlazeDS since it seems to do just this, mostly to avoid the crossDomain.xml file required by Flex to call webservices. However I can't seem to find any reference on how to connect through a Java client (probably using Axis2). Any suggestions, and especially tutorials, would be greatly appreciated.

  How do I use gl.gluUnproject in my OpenGL ES 1.1 android app to determine what is selected when the user touches the screen? My understanding is that the touch event results in a line and I have to find the first "thing" it intersects with. Are there any tutorials on how to do this?

• Javascript - Do I need to use 'var' when reassigning a variable defined in the function's parameters

  - by John Himmelman

  I've found many definitions of the 'var' statement but most of them are incomplete (usually from introductory guides/tutorials). Should I use 'var' if the variable & scope has been declared in the params list? someFunc = function(someVar) { // Is it considered good practice to use 'var', even if it is redundant? var someVar = cheese; };

• Is PyOpenGL a good place to start learning opengl programing?

  - by Isaiah

  I want to start learning OpenGL but I don't really want to have to learn another language to do it. I already am pretty proficient in python and enjoy the language. I just want to know how close it is to the regular api? Will I be able to pretty easily follow tutorials and books without too much trouble? I know C++ gives better performance, but for just learning can I go wrong with PyOpenGL? Thanks alot

• Where to start learning Java?

  - by Kerry

  I've been convinced that I should learn another language (primarily PHP/Javascript oriented) and decided on Java. I learned my basics of PHP, years ago, from www.w3schools.com and Javascript from another similar site (since taken down) that had a series of tutorials that took you from nothing to something. Is there a similar site for Java? Is there a recommended IDE (Eclipse?) and site to learn?

• Control statements in Haskell?

  - by Nathan

  I am just beginning Haskell, but from all the online tutorials I've found I can't seem to find if there is one accepted way to do a conditional control statement. I have seen if-else, guards, and pattern matching, but they all seem to accomplish the same thing. Is there one generally accepted/faster/more efficient way than the rest?
