  • Linux cannot alter partition table of main hard disk of my laptop

    - by djechelon
    I run openSUSE 12.2 on my ASUS N76VZ laptop. My problem is that I cannot alter the partition table of first hard disk /dev/sda1. YaST partitioner says it's unreadable, but actually it can read it but not alter it. It doesn't tell me anything else, except that I can wipe the partition table (having to reinstall Windows for the third time). Since I want to create new partitions on that disk, how do I fix the partition table layout? I could create new partition from Windows Computer Management and format them in Linux. I could do this, but it doesn't explain the problem

  • Linux/OS X dualboot on a Macbook Pro with RAID

    - by GaretJax
    I'd like to install Gentoo Linux on my Macbook Pro by keeping my current OS X installation. I currently have OS X installed on a RAID 0 on two 160GB Intel SSDs and I'd like to create a new partition for Gentoo alongside OS X without losing the RAID setup but, from what I read on the net, Apple's software RAID is poorly (read "not at all") supported: BootCamp refuses to create a windows partition on a RAID volume rEFIt is not able to boot an OS from a software RAID even Apple's recovery partition for Lion can't be created on a RAID volume Is there a way to dual boot my Macbook while keeping the RAID solution?

  • Difference between two ways of installing tomcat as a service (Linux)

    - by varesa
    I am installing tomcat on a linux server, and would want it to be available as a service. I have found two different ways to achieve this. The first one is to copy the daemon.sh from $CATALINA_HOME/bin to /etc/init.d, and the other one I have seen is to create a simple init script that class $CATALINA_HOME/bin/startup.sh, etc. Startup.sh calls catalina.sh. The contents of the daemon.sh and startup.sh look very similar (at least for the env variables, and stuff like that). Daemon.sh calls jsvc in the end. Catalina.sh calls java. What is the (practical) difference between using the two of these when setting up tomcat as a service?

  • How often does a Linux check it's /etc/localtime file

    - by DarkSheep
    I am trying to troubleshoot a problem. Some very helpful information would lead me to a solution is: Often does Linux check the /etc/localtime file? Additionally if there is a configuration file to increase the frequency (for testing) that would be helpful. Normally I would assume that it would check when a call to the ntp server has been executed, but NTP is not installed. It couldn't possibly check every time the date function is called as this would result in many problems on busy web servers. Server is Ubuntu 12.04, but I don't think that is relevant to the question.

  • Linux filesystem suggestion for MySQL with a 100% SELECT workload

    - by gmemon
    I have a MySQL database that contains millions of rows per table and there are 9 tables in total. The database is fully populated, and all I am doing is reads i.e., there are no INSERTs or UPDATEs. Data is stored in MyISAM tables. Given this scenario, which linux file system would work best? Currently, I have xfs. But, I read somewhere that xfs has horrible read performance. Is that true? Should I shift the database to an ext3 file system? Thanks

  • hdmi audio works only with aplay -D alsa test wavs; open source radeon drivers; kernel 3.5 vgaswitcheroo

    - by user108754
    I've trolled the internets to make hdmi work on my system Ubuntu 12.04 software center kernel 3.5 uname: Linux ubuntu 3.5.0-18-generic #29~precise1-Ubuntu SMP...x86_64 x86_64 x86_64 GNU/Linux open source radeon drivers vgaswitcheroo (hybrid intel/radeon gpu): I boot with intel, not radeon, running. (and recall that with kernel 3.5, vgaswitcheroo now gives info on a third item, "DIS-Audio"; it indicates pwr on my system) ( /etc/rc.local: chown user:user /sys/kernel/debug/ # change "username" with your user name echo OFF /sys/kernel/debug/vgaswitcheroo/switch ) grub indeed now has "radeon.audio=1" for testing audio, I did aplay -l which gave me the card and device, which made me try aplay -D plughw:1,3 /usr/share/sounds/alsa/Front_Center.wav and lo! I get crystal clear sound on my hdtv. If I play an mp3 file as the argument to that command, I get noise as, I guess, aplay interprets the mp3 code as a wav. If I play a .wav that is not in the /usr/share/sounds/alsa/ directory, I get nothing. Internet flash video in browser plays no sound over hdmi. Both system sounds control and pavucontrol have hdmi cedar selected. Alas, I can not get sound for any gui test (left, right). Why would only aplay, and only when directed with "-D plughw", yield sound over hdmi? I've also tried only using one sound program at a time, if it was a limitation of alsa, so I tried aplay with web browser and even the sound control gui closed. I tried each of the last two, running alone. No improvement. alsamixer only shows hda intel and I think it's only the intel audio, not the hdmi.

  • iPhone dev on Linux

    - by Daziplqa
    Hi guyz, Actually I have read about that I can write Objective-C app on Linux (using GNUStep). But my question is, Am I will be able to develop completely iPhone app on Linux machine? Or I'll need eventually need to use Mac machine? Especially when I read that there are some some syntax diffs between NeXT/Apple and GCC (according to http://en.wikipedia.org/wiki/Objective-C)

  • optimizing operating systems to provide maximum informix performance.

    - by Frank Developer
    Are there any Informix-specific guides for optimizing any operating system where an ifx engine is running? For example, in Linux, strip-down to a bare minimum all unecessary binaries, daemons, utilities, tune kernel parameters, optimize raw and cooked devices (hdparm). Someday, maybe, informix can create its own proprietary PICK-like O/S. The general idea is for the OS where ifx sits on have the smallest footprint, lowest overhead impact on ifx and provide optimized ifx performance.

  • Does the DMA Buffer Size should be same as UART FIFO size?

    - by ddpd
    I have written a driver for a UART in omap4460 panda board running on Linux platform.I have enabled DMA in FIFO mode in UART.My user application transfers 100 bytes of data from user space to kernel buffer(DMA buffer). As soon as the DMA channel is enabled, data from DMA buffer is copied to FIFO which is then transmitted to TSR of UART.Since my FIFO size is 64bytes,only 64 bytes is transmitted to TSR. What should I do to transfer remaining bytes from DMA buffer to FIFO?/ IS there any overflow occuring?

  • Is ColdFusion on Linux/Apache stable?

    - by Cyrcle
    I'm working on a site that still has a lot of scripts in ColdFusion. I need to move it to a new server. I much prefer Apache/Linux instead of IIS/Windows. I've seen some info here and there about running ColdFusion on Apache/Linux. Is that a stable setup?

  • pretty print makefiles

    - by wickedchicken
    The linux kernel (and various other projects including git) have very nice makefiles that hide the giant cc calls into nice little acronyms. For example: gcc -O2 -o cool.o cool.c -llib gcc -O2 -o neat.o neat.c -llib would become: CC cool.c CC neat.c Which is really nice if you have a project with a large number of files and long compiler flags. I recall that this had to do with suppressing the default output and making a custom one. How do you do it?

  • Converting jiffies to milli seconds

    - by EpsilonVector
    How do I manually convert jiffies to milliseconds and vice versa in Linux? I know kernel 2.6 has a function for this, but I'm working on 2.4 (homework) and though I looked at the code it uses lots of macro constants which I have no idea if they're defined in 2.4.

  • Ruby On Rails on Windows - Linux VM or dual boot

    - by CocoB
    I am a windows developer currently getting into Rails. While you can develop on RoR Windows, it's not the ideal experience. Things are glitchy and running cucumber tests are painfully slow. So, would I be able to have a decent dev experience running Linux in a VM for doing RoR development, or should I bite the bullet and just do a dual boot - Windows 7 / Linux?

  • How do you return stolen packets back to Netfilter

    - by meg18019
    Let's say I have intercepted a packet from Netfilter and subsequently returned NF_STOLEN. At some point I want to re-inject that packet back to, in this case, the TCP stream it came from. I want to do this from Kernel space. So far I have been unable to find a way to do this. Thanks for the help.

  • Do we need seperate file path for window and linux in java

    - by Kishor Sharma
    I have a file on linux ubuntu server hosted with path name /home/kishor/project/detail/. When I made a web app in window to upload and download file from specified location i used path "c:\kishor\projects\detail\" for saving in window. For my surprise when i used window file path name in my server i am still able to get files and upload them, i.e, "c:\kishor\projects\detail\". Can anyone explain why it is working (as window and linux both use different file path pattern).

  • per process configurable core dump directory

    - by Hanno Stock
    Is there a way to configure the directory where core dump files are placed for a specific process? I have a daemon process written in C++ for which I would like to configure the core dump directory. Optionally the filename pattern should be configurable, too. I know about /proc/sys/kernel/core_name_format, however this would change the pattern and directory structure globally. Apache has the directive CoreDumpDirectory - so it seems to be possible.

  • Storing data locally and synchronizing it with data base on linux server

    - by Miraaj
    Hi all, I have developed a mac application, which is continuously interacting with database on linux server. As data is increasing it has become costlier affair in terms of time to fetch data from server. So I am planning to store required data locally, say on mysqlite and find some mechanism through which I can synchronize it with database on linux server. Can anyone suggest me some way to accomplish it? Thanks, Miraaj
