  • Any reason not to disable Windows kernel paging?

    - by Nathaniel
    So I'm planning on eventually going to 2 GB (mobo max) RAM from 1 GB, and I want to disable kernel paging once I do, because I've heard it can give a performance boost (and that I believe). Any reason not to do it or any general thoughts about it? Edit: for clarification, this is not disabling general RAM paging. This is disabling having kernel memory paged (or at least parts of it, as Charlls noted).

  • user crontabs don't work, only /etc/crontab

    - by gletscher
    Hi when I use the command crontab -e to set up cron, the commands get triggered (according to syslog) but nothing happens. Also if I run sudo crontab -e. The only way to actually get cron working is to manually etc /etc/crontab I'm confused, since syslog gives me the same output for both methods. Any ideas for tracing down this bug? Thanks alot!

  • Vim: Custom Folding function done, custom highlighting required

    - by sixtyfootersdude
    I have defined a function in vim to properly indent folds. Ie so they look like this: Unfolded this is text also text indented text indented text not indented text folded with default function this is text also text +-- 2 lines: indented text ---------------------------- not indented text folded with my new function this is text also text ++- 2 lines: indented text ---------------------------- not indented text The only problem is the the highlighting is still like this: folded with my new function (highlighting shown with tag) this is text also text <hi> ++- 2 lines: indented text ----------------------------</hi> not indented text I would like the highlighting to start at the ++ and not at the beginning of the line. I have looked in the vim manual but could not find anything like that. One so-so solution I found was to make the background black. highlight Folded ctermbg=black ctermfg=white cterm=bold But this make folds less visible. I have tried several variations of: syn keyword Folded lines syn region Folded ... But I don't think that this is the way that folds are selected. Can anyone offer a suggestion? By the way this is my function to indent the folds: set foldmethod=indent function! MyFoldText() let lines = 1 + v:foldend - v:foldstart let ind = indent(v:foldstart) let spaces = '' let i = 0 while i < ind let i = i+1 let spaces = spaces . ' ' endwhile let linestxt = 'lines' if lines == 1 linestxt = 'line' endif return spaces . '+' . v:folddashes . ' '. lines . ' ' . linestxt . ': ' . getline(v:foldstaendfunction endfunction au BufWinEnter,BufRead,BufNewFile * set foldtext=MyFoldText() By the way thanks to njd for helping me get this function setup.

  • which factors determines the speed of a processor? [closed]

    - by Deb
    I think that clock rate of processor determines the speed of core, in my case it is 1.86GHz. But If I am not wrong, it also determines that how much energy it will consume. If you have more frequency then more power it will consume. I choose Power Saver scheme to increase my battery life, however it reduces my core speed to half of the actual speed. I understand this happens because of SpeedStep, but I don't see any slowdown of my computer. So my problem is why we have such high frequency cores as it uses too much power. We can use low frequency cores. Actually I get confused between the two terms Speed of the processor and its frequency. So how much important is the frequency of core in case of any processor.

  • How to fix an SSD

    - by anonymous
    I have a Samsung 128 go SSD : MZ5PA128HMCD-01000. When I'm using it : there is always I/O errors. I tried to secure-erase it. But it is impossible to create a new NTFS (or any filesystem...) partition because I still get I/O errors. I tought maybe upgrading the firmware will solve the problem. Unfortunately, I'm not able to upgrade the firmware with Samsung SSD Magician Tool ... because Magician says there is no Samsung SSD on my computer... Is there a way to make Magician recognize this Samsung MZ5PA128HMCD-01000 SSD? Is another tool available to flash any firmware on a SSD? What should I do to fix this SSD?

  • How to set resolution on mplayer with libcaca?

    - by AndrejaKo
    I'm using mplayer and libcaca on Gentoo. My framebuffer (uvesafb) is running at 1920x1200 (I don't know how many characters that is) and mplayer has problems filling up the screen, so video and audio lose synchronization. I'm looking for ways to improve performance. The most obvious solution would be to decrease resolution of mplayer, so I'm looking for ways to do that. Any other performance tips would be appriciated.

  • Weird mouse/keyboard freezups when using PowerPoint 2007 with IBM/Lenovo docking station

    - by DanM
    I'm not sure what part of my system is responsible for this, but when using PowerPoint, I have problems when trying to resize drawing objects. I'll be dragging the handle and suddenly, the object will deselect and whatever is behind the object will select and start moving around. Next thing I know, the keyboard won't type anymore, and the only way to fix it is to unplug the USB and plug it back in. In case it's hardware related, I'm using an IMB Thinkpad T60P in a docking station. My keyboard is a Microsoft Natural Keyboard Pro. My OS is Windows XP SP3. I've never noticed this happening in anything besides PowerPoint, and I don't know anyone else who has this problem (even people with similar setups). Any ideas what it could be? Edit Well, it looks like I only get the problem if I plug the mouse into my docking station's USB. If I plug directly into the laptop's USB, everything works fine. And, again, this problem is only with PowerPoint. I tried playing with some drawing objects in Word and had no issue no matter where my mouse was plugged in. I should also mention I tried a different mouse (a standard Microsoft corded mouse instead of my Logitech trackball), but that made no difference. So, I don't think it's anything specific with the trackball or the trackball's driver. I tried searching Google but came up empty, so I'm guessing this problem is something unique to my setup. If you have any thoughts or ideas to try, I'd love to hear them.

  • iPhone 3G S sync services problem

    - by Ryan McCue
    When I try and synchronise my iPhone with iTunes, I get a dialog informing me that "syncing has been disabled on this computer". (I've never disabled syncing myself, and it worked perfectly fine a day ago) Music synchronises fine, as do videos, however, my contacts do not. Google Contacts no longer appears in the list to choose from, and the select box is empty. When I choose to re-enable syncing, iTunes informs me that "iTunes was unable to load provider data from Sync Services". I've followed several steps I've found on the internet, including deleting the C:\Users\Ryan\AppData\Roaming\Apple Computer\Sync Services directory, but to no avail. Any ideas on what could be causing this? Is there a Service (in the Windows-form-of-daemon sense) that I accidentally disabled?

  • How do I prevent Pidgin from loading XMPP chat room history on join?

    - by Mr. Jefferson
    In Pidgin, when I join a chat room, it loads the chat room history. iChat on the Mac has a preference in the Accounts section to set a variable amount of history to load, or disable loading history entirely. How do I do the same thing in Pidgin? Is there a preference somewhere that I've missed? The object is to have the chat room start fresh each day, so I'd also be fine with disabling chat room history entirely on the server if that's possible. But I didn't see that option either when I looked in Server Admin on the server. I found this list of XMPP room types, and it looks like creating a Temporary Room might be the best way to do this, but I don't want to have to create the room manually every morning. Right now I've got Pidgin set to auto-join the room when I log in; I want it to do that without loading history. EDIT: The XMPP multi-user chat spec referenced above also contains a section on managing history. And I got this to work by pulling up the XMPP Console plugin in Pidgin, copying the <presence /> stanza it sent when I joined the room, closing the room, pasting the stanza into the console, adding the <history /> element and sending it. When I opened the room again, I had no history. But it all came back the next time! So: how do I get Pidgin to send the <history /> stanza by default?

  • Installing MySQL without root access

    - by vinay
    I am trying to install MySQL without root permissions. I ran through the following steps: Download MySQL Community Server 5.5.8 Linux - Generic Compressed TAR Archive Unpack it, for example to: /home/martin/mysql Create a my.cnf file in your home directory. The file contents should be: [server] user=martin basedir=/home/martin/mysql datadir=/home/martin/sql_data socket=/home/martin/socket port=3666 Go to the /home/martin/mysql directory and execute: ./scripts/mysql_install_db --defaults-file=~/my.cnf --user=martin --basedir=/home/martin/mysql --datadir=/home/martin/sql_data --socket=/home/martin/socket Your MySQL server is ready. Start it with this command: ./bin/mysqld_safe --defaults-file=~/my.cnf & When I try to change the password of MySQL it gives the error: Cannot connect to mysql server through socket '/tmp/mysql.sock' How can I change this path and see whether the mysql.sock is created or not?

  • Is it possible to extract contents of a ThinApp container?

    - by rsk82
    Is there possible to extract such packages made by somebody else. Ok, so if there is no general way of extracting such archives, which can be a huge exe file or tiny exe starter with huge packed *.bin file with main files of an app that is to be run in portable way - is there a way to set an option in compilation *.ini file or other way to make such package able to be extracted. I remember I read somewhere that somebody created a tiny program (in was mentioned in vmware forums as far as I can remember, it was a crude thing coded for private use and I never managed to download it) to sit with main portable application and if such application has an open/save file dialog, it is possible to navigate to that program which virtually sits in the program files alongside main app from within the main app, and such program would scan all files that it can see and somehow is able to distiguish a real file from virtual one, and save all virtual files in a structure that is similar to the initial compilation folder from which portable app was created. I know that it is a very round-about way of doing things, but maybe the only one feasible. Nevertheless any news on this front ? Do antiviruses can somehow unpack these things ? Maybe they must buy a code or license for it from VmWare ? Edit: I found http://communities.vmware.com/thread/257433?tstart=600 and still trying to make sense out of this. Wrong, this was about moving old version of thinapp to win7.
