Hey guys I was wondering if in an xcode build phase if it was possible to get the users root directory. Right now I am trying to copy it to "~/" but it says that doesn't exist Is there another way to get the user directory (or the users short name)? Or is there a system folder I can write to that won't run into permission problems? ...
I am using a timer in my C++ code through setitimer function from sys/time.h. This maps the SIGALRM signal to my timer handler method. After this I am not able to use sleep function. I am assuming it is because sleep uses SIGALRM signal as well. Can you suggest any workaround for this problem? Thanks for replying. ...
Two questions: how can I write a shell variable from this script into its child script? Are there any easier ways to do this? If you can't follow what I'm doing, I'm: 1) starting with a list of directories whose names will be stored as values taken by $i 2) cd'ing to every value of $i and ls'ing its contents 3) echoing its contents ...

Does the server need to have the .Net framework installed on it? (is this possible with non-windows servers?) Does the server need to have IIS installed on it? (is this poss...
I want to write a unix/linux program, that will use a configuration file. My problem is, where should I put the location of the file? I could "hardcode" the location (like /etc) into the program itself. However, I would like it, if the user without privileges could install it (through make) somewhere else, like ~. Should the makefile...
There are several good cross-platform libraries, by which we usually mean something that wraps the commonalities of Windows and *nix. Is there anything for developers that don't really care about Windows but want the benefits of C++ wrapping *nix system calls? I am thinking of a library that reduces the tedium of struct setup, checking...
I'm working on a shell script to convert MPO stereographic 3D images into standard JPEG images. A MPO file is just two JPEG images, concatenated together. As such, you can split out the JPEG files by finding the byte offset of the second JPEG's magic number header (0xFFD8FFE1). I've done this manually using hexdump/xxd, grep, head, and ...
Hi all, Having a regular size-efficient backup for only the modified checkedout elements in all views would be a great thing for us, since a great deal of the defined dynamic/snapshot views cannot be included in the daily backup policy. The following ksh code is near to what we would need for a dynamic view, but it trivially assumes tha...

Hi guys, One of the servers I'm working on regularly crashes/freezes and consumes ALL resources on the box. It will continue doing this until the process is killed (difficult to run manually since the box has no resources to allow me even to enter a command) or the box is manually rebooted. I'm not very experienced in unix OSes - can y...

I've been trying to find the answer to this for a while today and there's just so much contradictory information.... What I'd like to do is get a current unix timestamp in android, and then convert it to a format that allows me to getHours() and getMinutes(). I'm currently doing this: int time = (int) (System.currentTimeMillis()); Tim...

Why? Everywhere else I see people just run script/runner without the ruby in front of it... Is there a "fix" for this? It's causing ...
