  - by user367255

  How do you render the cursor and create highlighting for selected text in Pango? Also, can I use PangoCairo to render parts of a layout at a time, so I can draw it in different ways (such as with an outline)?

  - 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?

• 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.

  - 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?

• 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?

  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.

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

  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.
