• Is it possible to drag windows between workspaces when using Compiz?

  - by Mike Stone

  When I used Metacity, I could drag windows between workspaces using the small icon view of my workspaces. I recently started using Compiz for all the cool desktop effects, however this drag and drop feature isn't working. I use the cube effect for switching workspaces, but I noticed the wall effect doesn't allow it either. Is this just a missing feature from Compiz or is there a setting somewhere that I can enable it? I know that I can enable dragging windows across edges to the next workspace, and the expose feature to drag windows between workspaces. However, the drag and drop on the icon view is really powerful, and I would love to have it back along with all the great Compiz special effects.

• Upgrading mysql from 4.1.22 to 5.0

  - by Arsenal

  Hi, I'm trying to upgrade our company's 4.1.22 version of MySQL to 5. I'm using sudo yum --enablerepo=centosplus upgrade mysql* but keep getting an error of conflicted files with the 4.1 version. Does that mean there really isn't any other way than uninstalling 4.1 and installing 5.0? I have read that using the yum upgrade command should work however... Thanks in advance!

• Bash script, read values from stdin pipe

  - by gmatt

  I'm trying to get bash to process data from stdin that gets piped it, but no luck, what I mean is none of the following work: echo "hello world" | test=($(< /dev/stdin)); echo test=$test test= echo "hello world" | read test; echo test=$test test= echo "hello world" | test=`cat`; echo test=$test test= where I want the output to be test=hello world. Note I've tried putting "" quotes around "$test" that doesn't work either.

• Interacting with system commands using a web dev language

  - by Jamie

  Hi all, First of all, sorry for the vague title. Let me explain. At work we're currently using SunGrid I've been assigned a project to create a web interface wrapper for interacting with the engine. i.e. displaying users jobs, submitting jobs via a nice GUI etc. (most of the sgrid commands output xml which is nice) My question for you chaps is the following: What web dev language would you use to interact with the system? i.e. use the language to do a system call and evaluate the response. I'm not after an argument on which language is best, I just would like to know which language is specifically good for interacting with the system and is also good for web dev.

• bash and flock (file lock) - Doesn't seem to be locking....

  - by Rory

  I am playing with using flock, a bash command for file locks to prevent 2 different instances of the code from running more than once. I am using this testing code: ( ( flock -x 200 ; sleep 10 ; echo "original finished" ; ) 200>./test.lock ) & ( sleep 2 ; ( flock -x -w 2 200 ; echo "a finished" ) 200>./test.lock ) & I am running 2 subshells (backgrounded). The (flock NUM; ...) NUM>FILE syntax is from flock's man page. I expect that the first subshell will get an exclusive lock on test.lock, then wait 10 seconds, then print "original finished", all the time holding the lock. The second subshell will start at more or less the same time, wait 2 seconds, then try to get a lock on test.lock, but timeout after 2 seconds. If it gets a lock, then it'll print "a finished". If it doesn't get the lock, that subshell should stop, and nothing should be printed. Since the first subshell is waiting longer, it will keep the lock for 10 seconds, so the second subshell should not get the lock, and shouldn't finish. i.e. one should see "original finished" printed and not both. What actually happens is that "a finished" is printed, then "original finished" is printed. This implies that that the second subshell is either (a) not using the same lock as the first subhsell or (b) that it fails to get the lock, but continues to execute or (c) something else. Why don't those locks work?

• How can I link glibc statically with qt

  - by yan bellavance

  I have built a static version of qt and download a static version of glibc. Now I would like to link glibc statically to my qt application. I know about going into the .pro and adding the line LIBS += -L path/to/static_lib but I am wondering if these that is enough? Will it still link glibc statically even though the OS I am building on has the dynamic libraries also? The reason I am doing this is to deploy the application in a standalone manner. (After installing and updating Red Hat 5.3 glibc_2.9 was not found on the target computer)

• Debian Package Control file Question.

  - by AJ

  Hello, I need to create a debian package for a java application. In my package there a .jar file which is executable , a script which will run this jar file and a .so file for fmod. I read the tutorial provided at http://tldp.org/HOWTO/html_single/Debian-Binary-Package-Building-HOWTO/ My question is in control file there is a Depends field which basically mentions the packages that need to installed in order to install my application. How do i find which packages are required for my application. I followed the instructions provided in the link for one of the .so and did ~/Desktop/PennTotalRecall/native/fmod/lib/linux64$ dpkg -S libfmodex64-4.28.09.so dpkg: libfmodex64-4.28.09.so not found. It gives above result. Also my application requires java 1.5 to be installed in order for it to run. How do I specify in my debian package. Thanks, AJ

• How do I change bash history completion to complete what's already on the line?

  - by blokkie

  I found a command a couple of months ago that made my bash history auto-complete on what's already on the line when pressing the up arrow: $ vim fi Press ? $ vim file.py I'd like to set this up on my new computer, because it saves a lot of time when keeping a big history. The problem is that I can't for the life of me remember where it was mentioned and reading through endless bash references and tutorials unfortunately didn't help either. Does anybody know the command?

• Alternatives to ImageMagick for PDF downsizing

  - by Craig Coston

  Having an issue with some PDF files not displaying properly in our iPad app. I have come to the conclusion that we are needing to standardize by "converting" PDF to PDF. I have successfully processed this using ImageMagick to convert the PDF to PNG (resized), and then pushing the PNG(s) back into a PDF. However, something within ImageMagick is making photos within PDFs display wrong. Same issue just converting a JPG or other graphic to PDF in ImageMagick. I solved that by taking the output of the converted ImageMagick file and converting it again using GD to PNG, then pushing it through our PDF converter. So my question is this: What other PHP workflows would work with this, other than using ImageMagick for the conversion back to PDF? We are not opposed to a paid solution, we just need something that works. Our server runs centOS.

• How does fork() return for son process

  - by EpsilonVector

  I know htat fork() returns differently for the son and father processes, but I'm unable to find information on how this happens. How does the son process receives the return value 0 from fork? And what is the difference in regards to the call stack? As I understand it, for the father it goes something like this: father process--invokes fork--system_call--calls fork--fork executes--returns to--system_call--returns to--father process. What happens in the son side?

• Update RHEL 5.1 to 5.4

  - by Rayne

  Hi all, I have a server currently running RHEL 5.1, and I would like to upgrade it to RHEL 5.4. The server is not connected to the Internet, so I don't think I can use "yum update". How would I be able to upgrade my server, and is it just a small-scale upgrade, like Windows patches, leaving everything on the server intact, or would it delete everything that was on the server? Thank you. Regards, Rayne

• Creating a "less"-like console pager interface for pysqlite3 database

  - by Eric

  I would like to add some interactive capability to a python CLI application I've writen that stores data in a SQLite3 database. Currently, my app reads-in a certain type of file, parses and analyzes, puts the analysis data into the db, and spits the formatted records to stdout (which I generally pipe to a file). There are on-the-order-of a million records in this file. Ideally, I would like to eliminate that text file situation altogether and just loop after that "parse and analyze" part, displaying a screen's worth of records, and allowing the user to page through them and enter some commands that will edit the records. The backend part I know how to do. Can anyone suggest a good starting point for creating that pager frontend either directly in the console (like the pager "less"), through ncurses, or some other system?

• How to develop a DirectFB app without leaving X.11 environment.

  - by Edu Felipe

  Hi folks, I'm trying to develop a GUI application for an embedded platform, without any windowing whatsoever and I'm doing that with DirectFB, and it suits my needs very fine. Since the embedded I develop for is not that powerful, I would really like to try to develop on my own Ubuntu desktop. The problem is Framebuffer is conflicting with X.org causing me to leave the whole desktop, and shutdown X.org just to see the result of my changes. Is there a good framebuffer simulator that suits my needs? Qt has one, called QVFb, but it only works for developing Qt apps, and the VNC back-end of DirectFB always crash. So, any ideas?

• How the kernel gives seg. fault for a scenario like this?

  - by bala1486

  I have a doubt in accessing some invalid data. How will the OS cause segmentation fault for a scenario like this? Suppose a date segment has some 100 bytes. This will be mapped and a page table entry will be created. But the page size is 4K. Consider the data segment is aligned with this page boundary. So at first consider accessing a valid data within the 100 bytes. So now the page table entry is in TLB. Next if you try to access some invalid data between the 100 and 4K, the entry is there in page table and will it be allowed to access the invalid data??? Thanks, Bala

• File system to choose for NAS box based on FreeNAS or OpenFiler [closed]

  - by Chris

  I'm a photographer and I have a requirement find a better method of storing my photos other than multiple USB2 drives via USB hubs. Currently I use a Macbook Pro and 6 external drives connected via USB2 or FW800. 3 are a copy of the first three, kept up to day manually by running an rsync backup. I'd like to run a FreeNAS or OpenFiler NAS box using 2TB drives mirrored via software RAID. But - I would like to have the flexibility of also plugging into the drive physically for the faster throughput when necessary. So. My question is, is there a file system that both *nix and Mac OSX will play nice with? Many thanks, Chris.

• Pass potentially infinite number of arguments to array except a single numeric variable in a PHP com

  - by tehalive

  I'm trying to make a PHP script that will take a potentially infinite number of URLs from the command line as arguments. I also need to pass an argument that only has a single numeric value possible (to specify timeout), e.g.: ./urltest.php 60 url1.com url2.com url3.com I'm not exactly sure how to specify argv[1] to be a single numeric variable while at the same time the rest of the arguments (i.e. the list of urls) go into an array. Maybe something like: $timeout = $argv[1]; $args = func_get_args(); function numfilter($num) { return !is_numeric($num); } $urls = array_filters($args, 'numfilter'); ? Thanks in advance!
