• Are +=, |=, &= etc atomic?

  - by SF.

  Are the "modify" operators like +=, |=, &= etc atomic? I know ++ is atomic (if you perform x++; in two different threads "simultaneously", you will always end up with x increased by 2, as opposed to x=x+1 with optimization switched off.) What I wonder is whether variable |= constant, and the likes are thread-safe or do I have to protect them with a mutex? (...or is it CPU-dependent? In this case, how is it on ARM?)

• programmatically updating iTunes track location

  - by Ben Clifford

  I would like to modify the filesystem path for tracks on itunes programmatically, so that I can apply a string transformation to some of the tracks locations (which are now stored in a different places on the filesystem). I've tried using AppleScript to update the location property of the relevant tracks but I get an end-of-file error when calling "set mytrack's location to ..." I've seen various other hacks online that involve exporting the entire track db, modifying it in XML, and then reimporting it - but that seems to lose too much metadata (such as playlists).

• Scheduled Task: Directory cleanup using windows batch script

  - by d03boy

  I have a shared disk that I would like to clean up once per week using a scheduled task of some sort. I would like to use a batch script so that the system admins can easily modify it or reuse it on other directories when needed. The directory has files with multiple file extensions but the ones that need to be deleted end in .bkf and must be over 2 weeks old. Does anyone have a batch script solution for this windows server (not sure which version)?

• PHP output of foreach loop into a new array.

  - by RobHardgood

  I know I'm probably missing something easy, but I have a foreach loop and I'm trying to modify the values of the first array, and output a new array with the modifications as the new values. Basically I'm starting with an array: 0 = A:B 1 = B:C 2 = C:D And I'm using explode() to strip out the :'s and second letters, so I want to be left with an array: 0 = A 1 = B 2 = C The explode() part of my function works fine, but I only seem to get single string outputs. A, B, and C.

• Is it possible to add IPTC data to a JPG using python when no such data already exists?

  - by ventolin

  With the IPTCInfo module under Python (http://snippets.dzone.com/posts/show/768 for more info) it's possible to read, modify and write IPTC info to pictures. However, if a JPG doesn't already have IPTC information, the module simply raises an exception. It doesn't seem to be able to create and add this metadata information itself. What alternatives are there? I've googled for the past hour but to no avail whatsoever.

• Accessing a namespace containing .base in its name from F#

  - by emaster70

  As the title says, I'm trying to use a class declared in a namespace which contains "base" in its name. Think of a situation like the following: open Foo.base.Bar In C# I'd just use @ before base but F# seems to ignore that and to think that @ is the infix operator used for list concatenation. Since the namespace belongs to a third-party library which I cannot modify, is there a way I can still access it from F#?

  I've got a form that I downloaded, I'd like to prefill some content on the form (this is easy using cfpdfform).

• Should I be using callbacks or should I override attributes?

  - by ryeguy

  What is the more "rails-like"? If I want to modify a model's property when it's set, should I do this: def url=(url) #remove session id self[:url] = url.split('?s=')[0] end or this? before_save do |record| #remove session id record.url = record.url.split('?s=')[0] end Is there any benefit for doing it one way or the other? If so, why? If not, which one is generally more common?
