Does anyone know of any high-quality journaling software out there for F12KDE? I tried Keepnote, but it is not installing properly. Needs a Python(abi) dependency.
View 11 RepliesI've noticed that there are a lot of different programs out there to record your desktop (screencast), and it can be tricky to understand the differences between them, their limitations, and how to use them, so i made a video where i show how to choose between them, what their features are, how to USE them, and how to get the highest quality video from them.
You can find it here: High Quality Screen Casts, Desktop Recording, with Linux
I am currently in the market for one that has ogg/flac support on my next paycheck.

Now I am wondering if any of you had good experience with any other mp3 player on Ubuntu. The two things I want are firstly a product of high quality n functionality like those two mentioned above AND secondly a seamless ubuntu compatibility. I'd love to see synchronization and stuff working out of the box. Anyone out there found a outstanding product and like to give a recommendation?
View 4 Replies View RelatedI am trying to split a PDF into component pages that are of equal quality to the original. If I use display mypdf.pdf, then the PDF is split into pages of acceptable quality. The problem here is that I have to save each page individually. If, however, I use convert mypdf.pdf mypdf.bmp, I get the individual pages of the PDF in .BMP format (which is fine, but not exactly what I want), but the quality is substantially less than the original. I've tried dozens of combinations of commands to try to increase this quality, but to no avail.
Even if I do convert mypdf.pdf mypdfagain.pdf, there is a big loss of quality. Anyone familiar with splitting a PDF into individual pages without suffering a loss in quality?
Ideally, I would just save all the "scenes/frames" from display, but that feature unfortunately does not exist (though I may endeavor myself to add it if no formal solution exists).
NOTE: I think part of my problem might be: by using identify mypdf.pdf I can see that the resolution is specified, and when I convert it the resolution is much lower. This could be a source of quality loss, but I'm not familiar enough with image conversion to say that for sure. Whatever this command does, it removes the extra layer or whatever it is that prevents OCR from succeeding. I'd really like to understand that technology.. What is it about a PDF that allows an individual to embed some meta-data into every page of the PDF so that the only thing seen, say, through OCR, or a text search function, is the embedded text?
My laptop is a Dell Inspiron 510m with onboard Intel 855 sound (STAC 9750 AC97). The sound was perfect with WinXP, but with Ubuntu it's tinny and lacks richness and vibrates and distorts at higher volumes. I've played around with Alsamixer and changed the driver from ALSA to OSS4 and it has improved slightly, but still not perfect. Is it just not gonna get any better, should I not be expecting it to be as good as WinXP?
I've seen on the Intel site a Linux driver for my controller, it's a tarball but it won't compile after extracting it (read on this forum that someone had the exact same problem with that driver). Will the Intel driver not help, does the problem go deeper than just the driver? It would be perfect it you could just wrap the Dell/Intel driver and use that (just like with wireless ndiswrapper).
Where are the kernel headers for the current kernel of F12KDE? I am trying to configure VMWare player on my machine, and on initial startup I got an error message.
View 3 Replies View RelatedIs there a way to use JFFS2 (or other journaling file system) on an HDD? I'm looking for a file system feature that doesn't overwrite previously written data on an HDD.
Reason I'm asking is I'd like to use the capacity of the HDD as a log of all written activity, with the ability to retrieve old files. i.e. all writes to the HDD would be sequential.
I am trying to install debian on a slow netbook, and I can only install to a bootable SD card. The SD card is 200x, so it should be fairly fast. I was just wondering what filesystem would be the fastest, and use the least amount of cpu. I think it should be a non-journaling one, since this is flash media. I was thinking ext2 originally, but I heard ext4 has a non-journaling option, and is faster. However does ext4 take up more cpu usage?
View 2 Replies View RelatedI have an Acer Aspire One with an SSD for storage. I recently installed Ubuntu on it and chose ext4 for my filesystem. Then I read that journaling on an SSD isn't the best idea, so I will try to disable journaling and I have found these intstructions [URL]..
# Create ext4 fs on /dev/sda10 disk mkfs.ext4 /dev/sda10 # Enable writeback mode. This mode will typically provide the best ext4 performance. tune2fs -o journal_data_writeback /dev/sda10
# Delete has_journal option
tune2fs -O ^has_journal /dev/sda10
# Required fsck
e2fsck -f /dev/sda10

I will use them on my boot partition. Are there any particularly bad parts here, or are there any missing steps? Will my boot partition be fit for being on an SSD after this? Or should I consider switching to ext2, or even reinstall it all and choose ext2 at partitioning time (I'd rather not though, since I've configured quite some stuff already)?
I was reading a website about securely wiping data from your hard drive with wipe on the right click menu, when I stumbled across part of the article where it talked about journaling filesystems.Article
Quote:
There are three types of journaling: journal, ordered and writeback. Using shred, with an ext3 file system presents the user with the problem of secure deletion because it can only really be effectively used with ordered and writeback journals. It also lists ext4 as a journaling file system in the article, so I looked up the wikipedia page on it and I also found this:
Delayed allocationExt4 uses a filesystem performance technique called allocate-on-flush, also known as delayed allocation. It consists of delaying block allocation until the data is going to be written to the disk, unlike some other file systems, which may allocate the necessary blocks before that step. This improves performance and reduces fragmentation by improving block allocation decisions based on the actual file size. So I am confused about this delayed allocation thing. My thoughts are that ext3 and other journaling filesystems are bad to use with secure wipe when they are set on journal mode because that writes the file to the journaling sector as well as to the hard drive. Apparently, in ext3, the default was ordered mode. I would like to know if anyone has any idea if the ext4 file system on karmic 64bit is hazardous to the security of using the wipe command.
I use Slackware64 -current. I will buy a SSD drive, normaly the filesystem in my laptop is EXT4. Is there anything that I need to know? How to improve life of the SSD? Is journaling a good option? How to disable?
View 14 Replies View RelatedI have some very confidental files on my computer that I store such as credit reports, and other things. I always encrypt them with GPG, but there still is that original non-encrypted file left that needs to be deleted. I looked into tools like wipe, and shred but they all say that it really doesn't help on journaling filesystems directly on their man page.
I am not asking how to wipe the whole drive with dd or anything, but I am simply asking if there is a tool that'll delete a single file securely.
I bought a ssd drive for my laptop, installed it, installed Windows 7, installed Kubuntu 11.04. Till then everything worked fine, and I had following partitions on my disc:
Code:
/dev/sda1 ntfs ~100MB win boot,
/dev/sda2 ntfs ~170GB win main,
/dev/sda3 extended
[code]....
It worked fine. While using 11.04 I encountered a serious bug in nvidia 270.41.06, and decided to switch to Kubuntu 10.10. I installed 10.10 on the very same /dev/sda5 (clicking a checkbox to format it). Everything worked fine, grub was installed and pointing to win7, and kubuntu 10.10. I disabled ext4 journaling as above, rebooted, and found, that grub now points to win7 and 11.04, and that system (which should have been removed during installation of 10.10) loads perfectly fine. I checked where 11.04 had been installed - still /dev/sda5. Win7 loads fine as well, so no linux on /dev/sda2 I checked if there was 10.10 kernel in /boot - no. File system on sda5 had no trace of 10.10.
I formatted sda5 with gparted, installed 10.10 again, disabled journaling and situation repeated, whole file system on sda5 changed. Enabling journaling did nothing, 10.10 didn't come back. I deleted sda3, sda5, sda6, made them again, installed 10.10, disabled journaling, and finally had my 10.10 on ext4 without journaling. So this is kind of solved, but I would still like to know that the hell happend? For the moment it looked like two file systems coexistened on one partition.
I am currently working on a large document using LATEX and have bumped into a problem. Here is the thing: I write this document in several machines, there is a Mac at school, some Ubuntu based machine, and this Fedora 12 x64 laptop. The thing is that I compile the document periodically on these machines and I WOULD expect the results to be similar, but they are not because the resulting PDF is of inferior quality! (fonts do not look very well when they are zoomed in).
Mac OSX's latex-produced-PDFs are of higher quality than their Linux counterparts. Is there something I can do to fix that? Install an extra package perhaps?
After taking a first look onto internet under Fedora linux (using Firefox web browser) I've saw that every single image is displayer much much worse than in same Firefox under Windows. Especially when scaling, it became pixelized, but even without scaling it is smoothen very much. I've checked Konqueror but quality is bad too and the same as in Firefox. What could be the reason and how could I fix it?
BTW, everything in linux GUI looks a little worse, including font, etc, looks smooth. Images under IrfanView too, but not as bad as in browsers. Proprietary Nvidia driver from RPMfusion is installed and 3D works. But running Fedora under VirtualBox in Windows produce same bad quality as in native Fedora.
I installed Fedoa 13 from a Gnome Live cd which I had to burn on a DVD since I had no cd Available. I just saw that there is still the option to download the DVD image. Since my installation is quite buggy I'd like to know if installing from a DVD has better outcomes.

It seems I can play at least an mpeg movie, and mp3. But I find the quality of sound of the mp3 in kaffeine very poor. Yes, it plays, but some mp3's are struggling the first 10 seconds or so,, eg, Shivers - Armin van Buuren. When I play the same mp3 in xmms, it plays like a charm. That's not what I want, I want an all-round multimedia player. Xine does the job very well,, like xmms,, and plays also the mpeg, but unfortunately, xine shows an error message about a segmentation fault, upon exiting xine. Any hint to play mp3 files in kaffeine like xmms does?
I have a HP 3310 multifunction unit. Using HPLIP system it will print quite happily (though oddly the printer has to be on before the computer has booted for the networking to work!Now I'm trying to get the hang of scanning 35mm negatives using it + Fedora 12 (32bit). xsane seems to be the way forward, I can get a poor scan back but seem unable to find a way to tell the software I am scanning negatives and so to only scan the areas containing the film strip (HP provide a negative holder taht fixes the strip in right place on glass) to get higher quality scans. Anyone with any experience of scanning 35mm negs using HPLIPs/xsane/HP3310 ?

I was reading about ext3 feature and I have read about its journaling modes. I would like to ask what is the default journaling mode of ext3 fs in slackware(or is it in all distro using ext3)? I'll install slackware when my new pc arrive and the fs I will use will be ext3 and I like it to have data=journal mode for its journaling. I have read in some wiki how to set the journaling mode into data=journal mode.
Code: # tune2fs -O has_journal -o journal_data /dev/sdXY Do i need to issue this command or is this the default mode in ext3 in slackware?

I've just noticed that unrar is suddenly taking minutes to extract instead of seconds.
I can remember if its recently been updated, but I've uninstalled and reinstalled it and the version is: unrar.x86_64 0:3.7.8-3.fc10
I've found a few Ubuntu posts about it on Google, but in true Ubuntu fashion nobody has any answers!
What's odd is that when I unrar a file from (Nautilus or "unrar x *.rar") it takes say 4mins, then if I do it again it takes 15secs, like as if its caching somewhere.

I upgraded from Fedora 13 to 14 over the network. Everything seems to have worked. The one problem after my install is that I have noticed that setroubleshootd consumes alot of memory.
[Code]
It doesn't take long for setroubleshootd to jump in memory usage. I can kill the process but it will start up again. I have tried disabling the service but it doesn't show up in /etc/init.d. # service setroubledshootd stop setroubledshootd: unrecognized service So I am not sure what I can do to resolve the issue with setroubleshootd besides killing it off every 15 minutes.
I installed Fedora 12 on a new MacBook with a high def screen resolution (1680 * 1050) using Parallels. When Fedora runs, it run in a small window in the center of the screen - usable but far from desirable. Fedora 12 screen settings do not go as high as 1680 * 1050.
