General :: Configure A Single Computer To Work For Multiple Simultaneous Users?
Aug 17, 2011How can I configure a single computer to work for multiple simultaneous users? I would like to have multiple keyboards and monitors on a single PC ... Is it possible? This set up I'm planning for CyberCafe, For cyberCafe business ROI is very slow... so was planning to have something like this....
-single CPU (Which would act as a server)
-Multiple monitors, keyboards, Headphones etc....
If this works out then I would save a lot on my investments (OS cost, Hardware devices, electricity etc)
Ubuntu Installation :: Kernel Support For Multiple Processors?
May 13, 2010I just installed the latest version of Ubuntu 10.04 LTS, and am wondering if support for my dual AMD processors is built into the generic kernel, or do I need to compile a custom kernel? I have an HP tx2-1025dx touchsmart.

Jun 22, 2010I am using suse for a long time but I did not yet experience this strange error:
I installed 11.2 and now 11.3RC1 on a new HW: ASUS M4N72-E with AMD Phenom2 X4 965, 8GB Memory, standard settings.
I experienced unusual errors when copying large files to the new system with scp/ssh (connection broken).
Even stranger I could not read .tgz files created on the older machine, same OS 11.2, but MB ASUS M2N32-SLI with AMD Phenom X4 9850
Testing further reveals that if I create a .gz file from the same source it produces every time a different output:
-rw-r--r-- 1 root root 3875041280 Jun 21 01:51 wwtest.tar
-rw-r--r-- 1 root root 1326141906 Jun 21 01:55 wwtest1.tar.gz
-rw-r--r-- 1 root root 1326137319 Jun 21 03:26 wwtest2.tar.gz
-rw-r--r-- 1 root root 1326146273 Jun 22 07:32 wwtest3.tar.gz
[Code].....
I never saw something like it, I guess it must be something with the underlying library not working on the new processor. I tried with slower memory speed, newest BIOS etc ...always the same errors. Other wise the system works absolutely stable.
When I compare the generated files with one created on the older system it looks like there are single bits missing in a random number of bites.
General :: Get Multiple Video Cards To Work?
Mar 7, 2010I installed fedora 12.
I have 2 ATI cards that I used to use on windows to run 4 monitors. A recurring problem has been to get them detected in linux. Only my secondary card is picked up linux. When I manage the displays it detects the 2 monitors connected that card.
What are the specific steps I should take to get the second card detected? Supposedly there is a tool system-config-xfree. I don't have it, yum can't find it.
Also I heard it has something to do with editing some xorg.conf file or something to that effect. I have absolutely no idea how to find the "bus id" of my card, or lookup the horizontal refresh rates, etc..
I would probably have no problem following the documentation & editing the file if I knew a good way to find these values.
Someone also suggested installing linux twice and saving the xorg.conf it generates each time (with different card each time) and then merging the two by hand. That is like killing a fly with a hammer though, when I do this again and again in the future It'd be nice to not have to take twice as long.
Software :: How Force Multiple Processes To Run On Separate Processors
Sep 2, 2010when I start my application it creates a message queue and forks a process. The child process reads multicast packets from the network and writes to message queue. The parent process reads packets from message queue and compares source ip and sequence number (it is part of payload) with last 64K packets received to see if it has received a duplicate packet. I am using message queue as a buffer because I do not want child process to drop any packets while it is comparing it with previously received packets. The message queue is large enough to contain 64K packets. To compare the old packets I am using array of structures as circular buffer. During a spike I may receive 100 - 120 packets per milli second.
When I run my application, the parent process keeps up with the child process, I can see that with "ipcs -q". After about 30 seconds it cannot keep up and the size of message queue keeps increasing until it is full. When I run "top" I can see that one CPU/core is hundred percent busy while other 7 cores are idle. It seems that both processes are running on same core and the child process gets interrupts everytime there is a packet on the net and starves the parent process.I am running RHEL 5. The system has 24GB memory and my application is the only application running on it. It is a HP G6 server.

Jan 17, 2010I've been a Java developer for some time now and I always wind up removing a bunch of stuff from /etc/alternatives in favor of one of several freshly downloaded official Sun JDKs I've installed myself. I don't like circumventing things unnecessarily, though and I also don't like "re-inventing the wheel", either. If I had a better idea of how that system worked, perhaps it would not be required. I mean I usually write a script to switch between jdk's for different projects but perhaps I would not need a script if I knew how this worked

View 1 Replies View RelatedUbuntu Installation :: ATI Driver And New Kernel 2.6.35 Kernel - No Longer Work
Nov 24, 2010With the recent upgrade kernel, my ATI driver can no longer work. After upgrading to the new kernel, upon reboot I would get stuck at the "checking battery status" and can't boot into kubuntu.
I'm running Kubuntu 10.10 64 on intel i5 with radeon hd 4870.
So I thought I messed something up since I was fooling around with conky script the day before. I did a clean install of kubuntu 10.10 64 and reset all my settings and my files. At this point, everything works smoothly and I can reboot multiple times without a problem.
I proceeded to install the Radeon catalyst driver following the documentation, which worked perfectly for me on the previous kernel. After rebooting, I can no longer get pass the "checking battery state" black screen. I had to boot into safe book, uninstall all fglrx and also delete xorg.conf to be able to boot back in normally.

General :: Does Versions Control System Work On Server Or Per Website
May 26, 2011I tried hard so that I can stay away from version control but in almost good job specifications, I find version control as requirement. So I thought I had to start from somewhere. I always tried to read it but haven't got much luck with it. So I have few problems to ask. I am confused and I really want to know how can I use version control in my context and how will my working environment change with it.
I have Linux VPS Server. I use capnel/whm to create sites in php/joomla. So is version control a software or script which I can install on my linux box like ./configure. Or I have to install it on every site like any framework I use Dreamweaver to edit files via FTP. Now if I install version control then do I still use same method to edit files or then method gets chnaged What about the database like MySQL will it stays same or its also version controlled Will version control make my system slow and how much space it uses on my server.
