• WordPress-based ticketing systems?

  - by CarlF

  I have been asked to set up a ticketing/help desk system for a small nonprofit. Our server runs Debian GNU/Linux. Because we already have WordPress installed and plan to exploit it heavily going forward, I'm wondering whether there are any WP-based ticketing systems. Obviously, it will simplify the admin's life to have less software installed on the server. Thanks.

• A smart UDP protocol analyzer?

  - by ripper234

  Is there a "smart" UDP protocol analyzer that can help me reverse engineer a message based protocol? I'm using Wireshark to do the sniffing, but if there's a tool that can detect regularities in the protocol (repeated strings, bits of the protocol that are CRC/Checksum or length, ...) and aid the process that would help.

  - by Alien01

  What is the best process where code is checkedin by developers, installer is created by build engineer and release to QA to test the installer. Should the installer be release to QA without unit testing by Dev.

• What options do I need to pass to compile something to /usr/lib64?

  - by Phillip Oldham

  I'm trying to install a newer version of libevent than is on my machine, so I can install memcached. However, the install for memcached complains that the libevent library isn't in /usr/lib64 and that it isn't 64bit. What options do I need to pass to ./configure to get it to compile as 64bit and/or into the /usr/lib64 directory? This is what I have at the moment: CHOST="x86_64-pc-linux-gnu" CFLAGS="-O2" CXX=gcc CXXFLAGS="-O2" \ CC=gcc CXX=gcc \ ./configure --prefix=/usr Thanks!

• Dereference symbolic link in OS X?

  - by ithinkihaveacat

  In OS X, how can I dereference a symbolic link to a canonical file name? (i.e. one starting with /.) That is, I'm after the equivalent of GNU readlink's -f option: kapow:~$ greadlink -f .bash_profile /Users/mjs/.config/home/.bash_profile OS X's readlink instead returns a relative link: kapow:~$ readlink .bash_profile .config/home/.bash_profile stat(1) does have an amazing number of options, but I couldn't figure out the right combination to do what I want.

• How do I strip local symbols from linux kernel module without breaking it?

  - by Kimvais

  If I do --strip-debug or --strip-unneeded, I have the .ko that lists all function names with nm, if I do just strip foo.ko I have a kernel module that refuses to load. Does anyone know a quick shortcut how to remove all symbols that are not needed for module loading so that people cannot reverse engineer the API:s as easily? PS: For all you open source bigots; this is something that general public will never be using in any case so no need to turn the question into a GPL flame war.

  I am running mysqldump on Ubuntu Linux (10.0.4 LTS) my mySQL version info is: mysql Ver 14.14 Distrib 5.1.41, for debian-linux-gnu (i486) using readline 6.1 I used the following command: mysql -u username -p dbname dbname_backup.sql However when I opened the generated .sql file, I saw that most of the tables had only the schema dumped and in the few cases where the actual data was dumped, only 1 or two records were dumped (there are ATLEAST several tens of records in each table). Does anyone know what maybe going on?

• What is the difference between the Client and GTK versions of emacs?

  - by David

  My Ubuntu 10.04 desktop has three versions of emacs: emacs-snapshot (client) emacs-snapshot (GTK) GNU Emacs 23 I mostly use emacs-snapshot, but I also use regular emacs in terminal mode emacs -nw. However, it is not clear to me what the difference is between the client and GTK versions of emacs-snapshot is, which one is launched by emacs-snapshot at the terminal, and if I should uninstall one or just ignore it.

• Is $70/h is a good salary ?

  - by MikeJailrod

  Hi. One of my friends has contacted a company that is looking for good, linux network programmers in C, requiring a good background of the linux kernel and low-level network programming. The starting payment would be $70 per hour - I am still at college and honestly i don't know if that's a good salary for such a work as linux network engineer, so i am asking here if $70/h is good enough or not ? Thanks.

• Find out how many memory my server would need ideally?

  - by Daniel

  I have a pretty busy GNU/Linux server that I think needs more RAM. I know that the free command doesn't show the amount of RAM that is used. So I was stumbling upon Commited_As in /proc/meminfo. It currently shows 57972 kB which isn't much. Is this the amount of RAM that the processes use "right now" or is this an estimate of how many additional RAM it would take to never run out of memory with this load?

• browser instant updates with ajax/jquery

  - by wcpro

  I'm trying to reverse engineer how facebook handles their notifications, where when you get a message you get instantly notified via the browser. I've fiddled with it for a little bit and realized that there is always a pending GET request "listening" if you will to some sort of update from the server. This appears to be some sort of observer pattern. I was just wondering if this pattern was documented somewhere.

• How can I tell if my hard drive(s) have Battery Backed Write Cache?

  - by Riedsio

  How can I tell if my hard drives have a battery backed write cache (BBWC)? How can I tell if it is enabled and/or configured correctly? I don't have physical access to my server. It's a GNU/Linux box. I can provide supplemental incremental information/details as requested. My frame of reference is that of a DBA -- I have access and privileges, but (usually) only tread where I know am supposed to. :)
