Is there any compression software that supports PAQ8 and its variants with a graphical interface for Fedora (i'm using x86_64)? What's the best compression algorithm known to man? Time taken to compress is not a problem, just need to have the best compression available. Is there any program for linux?

hy I can't make a 7z archive with file roller? I have already installed p7zip, p7zip-plugins, and 7za. I don't understand what the problem is. I can make a 7z archive from the command line with no problems. I keep getting this message but it doesn't tell me what the error is. Quote:An error occurred while adding files to the archive.

If I, under M$, turn on the NTFS compression, will that drive still work under LINUX?
My thought is that it won't as I haven't seen any control in LINUX for it.
Fedora provides several compression techniques. E.g tar, tar.gz, zip etc. I want to know which among them provides
1. the best compression ratio for text files
2. the best compression ratio for binary files
3. fastest compression
You right click on a file and choose Compress. How do you select the compression level for algorithms that support different levels? If you can't, what compression level does it use?

how to do Lempel-Ziv-Welch compression using pen and paper for my algorithms and data structures class. Unfortunately we have only a couple of examples in our book of how it is done. I'd like to practice compressing and decompressing text using it, but I need to find a way to check if I'm right doing it right or wrong.
So I'm looking for some preferably free/open source program which can compress and decompress LZW for Windows or GNU/Linux. Programs without binary distributions are fine too.
Given a gzip compressed file, how do I know what compression level (1-9) was used for it?

I use mplayer to play my media files. Occasionally I want to take screenshots of media I am playing. I use the -vf screenshot option to take screenshots which generates shotxxxx.png. The issue is that all those png are not compressed and usually large. When dealing with Hi-Def media they are extremely large, each is 4-5 MB in size at the least. Is there a way I can set the option for compression of png images. If I use imagemagick the same files get compressed to like 1.5MB of png file.
View 4 Replies View RelatedI am working on a project where I am dialing out of a modem!! Old stuff, ya, but the modem allows my device send info from remote sites from my datibase through a phone line so that this IT departments dont have to worry my device being a security issue on their networks.
Any way, the modem I'm using isn't incredibly well designed, and when a certain ascii char is read by the modem, it reads it as an EOF indicator. It is also important that the files I send are compressed.
My question is: Does anyone know of a compression format that allows ME to dissallow IT's use of certain ascii chars?
just as an illustration:
Device --------> Modem ---------> Off-site
and the Modem stops talking to the device when a certain char is passed to it.

View 1 Replies View RelatedI compressed a directory containing many image files. The directory amounted to 5.3gig. Compressed with TAR using .tgz the compression took a couple minutes at most and compressed down to 4.3 gig. Compressed using .bz2 the compression took about 90 minutes and compressed down to 4.2 gig. Hardly worth the extra time. Do these numbers look normal to you?

How do I adjust the flac settings in Banshee to do this? The option to edit the settings is not available for flac? I guess there is a config file somewhere?
I am trying to convert hundreds of BMPs into a single AVI file, without compression. Since every pixel matters in my case, I don't want any kind of compression. It's fine if the output file is extremely large.
I'd like to know if it's possible to achieve this with packages coming with Ubuntu 11.04. I have tried ffmpeg/mencoder, but they either compressed the output file, or the output file is not playable in totem. I am a new user for both tools. there is actually a way to get uncompressed avi from these tools.
"BMP to AVI Sequencer" [URL] does the job perfectly. I successfully converted 180 1080P BMPs into a 1G avi, running at 30 fps. Unfortunately I need a command line tool this time.
We have been using an Ultrium LTO-2 tape drive to perform backups of certain information from our file server. Recently, the data that we are backing up has grown too large to fit on the tapes in their 200GB uncompressed capacity. I have been looking around for a way to enable the compression in the drive, but I haven't found much. I am not using any backup software, so I'm not sure if I'll even be able to. I write the tape using a simple 'tar' command, so there aren't a whole lot of options to be set. Is there a way that I can enable the drive's compression, or would I be better off running the tar command with the gzip or bzip flags?

View 3 Replies View RelatedI have a script which periodically backs up a directory using the command "tar -czvf [name] [directory]" but my problem is that the script has recently been putting a lot of stress on the server (Minecraft SMP) and tends to lag players as it backs up, which recently has been taking nearly 5 minutes.So I need to know if there's a way to control the GZip compression rate at the same time that it archives and backs up the files?I understand that I can first tar the files and then GZip them separately with a different compression rate afterwards, but this would not work because it names the files with the current server time, which sometimes changes in between commands.
View 1 Replies View RelatedI finally got K9copy to work and I'm using it to extract DVDs to my hard drive. I extract a dual layer DVDs it becomes a 5GB DVD. In the settings, I have DVD size as 9GB because I assumed this would not cause any compression. When I use k9copy assistant to change the shrink factor before ripping, I can only change the shrink factor of some titles to 1.67 from 2.50. I want the shrink factor to be 1 since this seems to ensure that the output of the file is the same size as the title on the dvd. I want the copied DVD to be the same size as the original. I have no problem with hard drive space since I have 6 terrabytes of free space.
View 6 Replies View RelatedI'm head engineer for a community radio station. One of our compressors has recently died and I want to replace it with software compression on our streaming machine. I've been looking at VST/LADSPA/JOST etc and I've got nothing but confused. Hence I'm coming here looking for help.
My spec is this. We need a system to run a compressor and EQ, probably a graphic and a parametric. The compressor needs to be multiband and have proper control of the compression curve. A way of configuring it without too much command line work would be an advantage. All needs to run on an Ubuntu server with not massive overhead as it's not exactly the latest hardware. I suspect it would be possible to run WINE for windows requiring VSTs if needed.
I was hoping some of you good people might be able to point me in the direction of a suitable host and plugins to achieve the effect described.
I am trying to install a PCIe card for data compression in Linux ubuntu 9.10(karmic Koala). As you can see in the following code although I have the root access I can not get permission to install the device driver.As I have the root access I suppose to get access to install the driver. I checked around and got the procedure from a web siteEnabling root access in unbuntuBasically in almost all linux machines we will be havingroot access for login.but in ubuntu by default that option was not enabled.If u want to have root login in ubuntu then u have to do some changes in ur Ubuntu machinesSteps to follow1.First enter into ubuntu as your user login.2.Then open the terminal and type the command sudo -s,it will ask for root access and type the password.3.Then type passwd root it will ask for new password4.Open terminal and go to the path /etc/gdm/5.Open gdm.conf6.search for AllowRoot=false7.and then change AllowRoot=true8.now restart ur machine9.now u can enjoy with root accessThe funny part is when I search for the file which is gdm.conf in the prescribed location, I can not find it.
