While coding Python, I tend to save files very often (I have a pretty high code->test->code->test->... frequency). I hate when Linux syncs my changes to disk everytime I do a write.
How do I configure Linux so that it keeps file writes in memory for a certain period of time/number of writes?
To make this any useful, of course reads to not-yet-fsynced files must be from memory (so that the Python interpreter always sees the latest contents). Extra credits for background-fsyncing that doesn't block other writes/reads going on at the same time :-)
When I try to mount a linux file system that was encrypted using cryptsetup I get the following error: debian:/# mount /dev/sdb3 Command sukey slot 0 mount: u moet een bestandssysteemsoort aangeven mount failed with run_sync status 32 Command failed: Device busy mount.crypto_LUKS(crypto-dmc.c:168): Could not unload dm-crypt device "/dev/mapper/_dev_sdb3", cryptsetup returned HXproc status 240 "mount: u moet een bestandssysteemsoort aangeven" is dutch for "you must specify filesystem type"
I've discovered Firefox Sync a while ago, and it's absolutely awesome. Now of course I'd like most of my software to work this way! So is there a way to get the same behavior with Thunderbird?
I've had a look at some similar threads but as I'm very new to linux they're already a bit technical for me. Sorry, this calls for someone with patience. I gather from other threads that disconnecting an external drive without unmounting is a no-no, and this seems to be the likely cause. Now the disk is read only and I'm unable to change any settings through the usual control panel on ubuntu. I'm just not familiar with the terminal instructions. I tried to cut and past a few command lines from other threads but I got some warnings that proceding could damage data. Like this one: WARNING! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage.
I am very new to linux, and I have a question regarding the filesystem check (fsck). The power recently went out and when I tried to restart linux the following error appears:
*/dev/sda1 contains file system w/errors, check forced it then goes on to say..
*An error occured during the file system check. Dropping you to a shell; the system will reboot when you leave the shell. Give root password for maintenance (or type Control-D to continue) I wasn't sure what to do, but checked some other online forums and they suggested running fsck manually - so I typed in the root password - and used the command, "fsck -A -V ; echo == $? ==" it then gave the following message
*WARNING!!! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage *Would you like to continue (y/n)
Again, I wasn't sure what to do so i just checked no. I then manually turned off the computer and was prompted at the beginning to press Alt-3. I was brought to another screen and it informed me one of the drives was degraded and suggested rebuilding the array. I tried doing this, but it still brings me back to the original error of, "/dev/sda1 contains file system w/errors, check forced," and the process continues.
Also, when I tried to rebuild the array, I didn't backup any of the data on our home directory before doing this (which was probably a big mistake). After being prompted to type the root password, I was able to give the ls command and look at all the directories...the home directory where our data was stored was empty and I am afraid I may have lost some information. Is there a possibility that data was lost when I was trying to rebuild using the old drives?
I use jpilot on opensuse 11.3 64bit to sync pim data with my Palm Treo 680 via bluetooth. This worked fine until today. Now I get the following error message when I try to sync: Syncing on device bt: Press the HotSync button now dlp_ReadSysInfo error Exiting with status YNC_ERROR_PI_CONNECT Finished.
The last successfull sync was on the 20th October and today is the 24th October. I did not change any settings in jpilot or on my palm device. So I guess there must have been an update of opensuse which causes this error. But I do not now how to look up the updates during this period or how to undo them. Was there an update between the 20th and the 24th Oktober, which might affect either jpilot or bluetooth functionality?
I've got Ubuntu One syncing a single 25MB folder on 4 computers. On one of these computers, the ubuntuone-syncdaemon process constantly pegs the CPU, using from 50-80% long after any sync-able files have been modified and successfully synced. The process is only using 8.9MB of RAM.
Specs: Ubuntu 10.04 (lucid) Kernel 2.6.32-24-generic 1000.8 MB RAM Pentium 4 2.53GHz Free disk space: 280.9 GB System monitor shows 56.8% total RAM usage, 15.4% swap file usage.
Audio sync method. "Stretches/squeezes" the audio stream to match the timestamps, the parameter is the maximum samples per second by which the audio is changed. -async 1 is a special case where only the start of the audio stream is corrected without any later correction.Searching the net makes one believe that this command is just some sort of magic.People just put it in the line and it just works. Isn't that nice?
It says nothing about how to change the TIME the audio starts syncing. Like do I want it to start 5 seconds delayed? Or what about 5 seconds sooner?What if the audio gets more out of sync as the video goes on? Can I slip it a little at a time? What? No magic?No one mentions a file that already has badly synced audio.So what -async 1 really does is simply start the audio at the beginning of the file. LIKE AS IF THAT ISN'T STANDARD PROCEDURE?So what is the exact solution to syncing a messed up video? And why can't it just do the proper "timestamp" sync in the first place?No docs, no info and you are left out in the cold.
Anyone know why each time I boot up the machine the cube background image goes away and the background colour is left. This image i am placing is in Apparency/Skydome
It seems that selinux has stop weav to sync the bookmarks.I followed the fix code as SELinux suggested,but it can't work.Does anyone know how to solve it?
When I try to boot to OpenSUSE I get the following error during boot-up: unknown filesystem type 'reiserfs' could not mount root filesystem - exiting to /bin/sh$
This only started happening quite recently - before this I could boot to Linux quite happily.
I have a following problem: Recently my drive with Ubuntu 9.4 has mysteriously stopped working, i.e. when I switch the computer on it informs me that GRUB didn't find the filesystem. Well, I suppose it happens.
First, I though it was due to the drive dying, but I popped it in an external enclosure and HDTune told me the drive was fine. Wanting to recover the files on the drive before reinstalling I first tried to mount it in said external enclosure under Windows (I have Win Ext2 driver installed which used to work just fine). This time, however, drive gets assigned a letter but upon opening it Windows popped up an error saying that the drive was not formatted and whether I would like to format it then.
Unfazed by this streak of failures I tried to mount it under Linux but, alas, to no avail. I might have tried every single -t operator under mount command but it still won't budge and let me mount.
I originally have Ubuntu Lucid on my machine. I just installed opensuse 11.2 on another partition without bootloader installed. So I'm still using the Ubuntu Lucid default bootloader grub2. I can boot up opensuse correctly. the nagging thing is that there's no splash screen show up during the boot process, instead, lines of command are flashing, the console background is also missing and the font under console (tty1-6) is huge. what can I do to have these back to opensuse? the current entry in grub2 for opensuse
Code: menuentry "openSUSE 11.2 (i586) (on /dev/sda2)" { insmod ext2 set root='(hd0,2)' search --no-floppy --fs-uuid --set 9ac05ede-e7c4-47f3-b55b-66d5844$ linux /boot/vmlinuz-2.6.31.12-0.2-desktop root=/dev/sda2 initrd /boot/initrd-2.6.31.12-0.2-desktop } which parameters should I add?
Migrated my wife to Linux when her old computer broke. She has an old iPod (one of the first ones to show video) that has music and playlists on there. I know how to sync podcasts to my iPod shuffle with gPodder and GTKpod. But how would I sync up files with her iPod? Also, what program would I use to automatically sync the iPod with any music dropped into her Music folder? This should be as painless as using iTunes or she won't do it.
On my network I have one computer running Fedora 14 and another running Ubuntu 1.0. I need to sync Evolution between these 2. The problem is Evolution folders have different content in the 2 distros. Is there a way to sync e-mails, contacts etc, between these 2 distros?
I'm trying to sync the clock of an ubuntu desktop with the network with ntpdate -u <ntp-server> and in a matter or minutes it's growing an offset of a few hundred milliseconds and even more than one second. Is there anyway to guarantee that the time keeps synchronizing with the network more frequently? does it make sense that the offset grows so fast? Am I doing something wrong?
I have spent the most part of 5 hours trying to fix this issue. For some reason I cannot change the background image to any of mt .jpg wallpaper files (and .png files). I've tried using the Ubuntu-Tweak application, but I end up getting a purple screen (default) or a black screen (default). So then I tried using the terminal method by making the Appearance window appear when I would log out. That works, except when I go to use my background image, it shows as a question mark for the image preview, and the icon for the file is a gray box. All while doing this my background images that I tested are all in the /usr/share/backgrounds location. Please help! I really want to get rid of the default images and use my images... :/ My desktop/screen in 1440x900, and most my background images are around that size. They work with my regular desktop for my account.
I'm using a Linux machine at work, and started using at home in a VM for some home development. I have a vimrc and a bashrc with some configuration, that are useful for both machines. What is the best way to sync them? Create a symlink for each file in my home folder pointing out to a the respectives files in my Dropbox sync folder? Is this possible (delete .bashrc and create a symlink instead)?
So I created a new branch from master and eventually merge the changes back, only some changes seemed to merge and it would seem I merged in one direction. Eventually I just decided to be sure master received all the 'experimental' changes then I deleted the experimental branch and made a new one. So this question is turning into a few questions suddenly:
1) How do I match up branches but keep them separate?
1a) Is that bad practice to not just make a new branch?
2) Why were the branches not the same after after one merge?
2a) Am I only supposed to call a merge on the one that I want to have all of the changes?
I have several devices (server, tower, notebook, android phone). I want to have my music library in sync on all of them. So what I thought of was a revision control system that just takes care of CRUD actions (or rather CRD). Maybe it could keep track of the files using their initial name and tracking any renaming or deletion. All popular software I know (git, svn, cvs, ...) is out of question because they save too much overhead (they diff the binary files).
Streaming doesn't work either for me because I don't always have an internet connection. Synchronizing the music using tools like unison is very inefficient too because I write metadata to the files so their hashsum, timestamp and size change constantly. If there is a diff or sync tool that ignores minor changes in size and ignores timestamp and permissions and so on, it would maybe be fine but I don't know one.
I wanted to create a consistent sync between two directories on two separate hosts. So when I write a file on one host, the file is automatically written on the next host. I don't have shared storage between each host.
