  • Using tar, the entire folder structure is including, I don't want that

    - by Blankman
    I am taring a folder and for some reason the entire directory structure that preceds the folder I am tarring is included. I am doing this in a script like: 'tar czf ' + dir + '/asdf.tgz ' + dir + 'asdf/' Where dir is like: /Downloads/archive/ In the man pages, I see I can fix this but I can't get it to work. I tried: tar czf -C dir ... But now I have some kind of a file -C in my folder (which I can't seem to delete btw!). Please help!

  • Did You Know? I gave two presentations last week

    - by Kalen Delaney
    Even though I didn't make it to TechEd this year, it didn't mean I was quiet last week. On Wednesday, I was in Colorado, giving a talk for the new Colorado PASS User Group, which is a joint venture between 3 different existing groups from Colorado Springs, Denver and Boulder. On Saturday, I spoke at SQL Saturday #43, in Redmond on the Microsoft campus. My presence there has already been mentioned on two other blogs here at SQLBlog: Merrill Aldrich and the infamous Buck Woody . As Merrill mentioned,...(read more)

  • thunar-archive-plugin not working

    - by Sergio
    After I experienced serious not yet resolved performance issues with Nautilus I decided to move to XUbuntu so I installed its metapackage from Ubuntu and started using it. It turns out that the archive plugin for Thunar (provides the "Extract here" option in the contextual menu when right clicking over a compressed archive) is not working, even after I apt-get purged it and reinstalled. It simply doesn't show its options in the contextual menu. What should I do to make it work?

  • 284 GiB of data, 217.4 GiB of space

    - by Malfist
    I want to reinstall my OS, but I don't have the hard drive space to backup any more (I have a RAID 1 array, so I haven't done it for a while). In my /home I have 284.8 GiB of data, and I have a spare 250 GB (or 217.4 GiB) hard drive that I've been using for backup. What type of compression algorithm (if any) is capable of this type of compression? I don't care about the time, I have a quad core though, so something that utilizes all 4 cores would be great. I have tried 7zip with no success. Ran on one core for two days and failed because of lack of space. Any ideas?

  • Sanity checks vs file sizes

    - by Richard Fabian
    In your game assets do you make room for explicit sanity checks, or do you have some generally expected bounds which you assert? I've been thinking about how we compress data and thought that it's much better to have the former, and less of the latter. If your data can exceed your normal valid ranges, but if it does it's an error, then surely that implies you're not compressing the data well enough? What do you do to find out if your data is compressed as far as it can be, and what do you use to ensure your data isn't corrupted and ensure it's an official release? EDIT I'm not interested in sanity checking the file size, but instead, how you manage your sanity checks and whether you arrange the excess size caused by the opportunity to do sanity checks by using explicit extra data, or through allowing the data enough file space (data member size) to be out of valid range and thus able to be checked merely by looking at the asset in memory after loading.

  • Compress a directory in linux

    - by user9589
    I'm trying to compress a directory and ftp it to a windows ftp. I have tried ever tar command i can find to compress a directory. It appears to be ok then I try and view it's contents using winrar. Winrar keeps telling me the file is corrupt. I have viewed other .gz or .bz2 files using winrar but for some odd reason I can't get it to work. Does anyone else have a suggestion as to something else to try. I would prefer just to have it zip the files so they have a .zip extension but even then when i try to browse it's contents both windows and winrar claim it's corrupt.

  • What data-structure/algorithm will allow me to send a list of key/value dictionaries using the least amount of bits?

    - by user12365
    I have server objects that have corresponding client objects. The data to be kept in sync is inside the server object's key/value dictionary. To keep the client objects in sync with the sever objects, I want the server to send the key/value dictionary every frame for each object. What data-structure/algorithm will allow me to send a list of key/value dictionaries using the least amount of bits? Bonus constraint 1: For each type of object, the values of some keys change more often than others. Bonus constraint 2: Memory usage on the server side is relatively expensive.

  • How can I maximum compress video files?

    - by EmmyS
    I received 4 .mov files from a client that they want on their mobile website via SlideShowPro. Each original file was between 200 and 400 mb. I've gotten each one down to about 30 mb using transmageddon as described here, but that's still really big for a mobile connection. Is there any way to shrink them even further? Maybe it's the settings; I used Output Format = MPEG4, Audio = AAC, Video = H264 (which is what is suggested by SlideShowPro.)

  • Is it possible to modify a video codec + distribute it?

    - by Nick
    this is my first question on this particular stackexchange node, not sure if it's the most appropriate place for this question (if not, guidance to the appropriate node would be appreciated). the abstract: I'm interested in modifying existing video codecs and distributing my modded codecs in such a way as to make them easily added to a users codec library... for example to be added to their mpeg streamclip, ffmpeg etc. some details: I've had some experience modifying codecs by hacking ffmpeg source files and compiling my hacked code (so that for ex: my version of ffmpeg has a very different h.263 than yours). I'm interested now in taking these modified codecs and somehow making them easily distributable, so others could "add them" to their "libraries." Also, I realize there are some tricky rights/patent issues here, this is in part my motivation. I'm interested in the patent quagmires, and welcome any thoughts on this as well. ctx link: if it helps (to gauge where I'm coming from) here's a link to a previous codec-hacking project of mine http://nickbriz.com/glitchcodectutorial/

  • Is it safe to compress my Windows 7 %USERPROFILE%\AppData folder?

    - by Kev
    Having just read Scott Hanselman's latest blog entry, Guide to Freeing up Disk Space under Windows 7, he suggests turning on NTFS compression which I already do for a number of less travelled folders that contain static files such as downloads or images. However I am wondering if it's wise to turn on NTFS compression for the whole of my %USERPROFILE%\AppData folder? My system drive is a 128 GB SSD residing in a Dell Precision T5400 3Ghz Quad Core Xeon workstation so I ought not to notice the extra cycles used to compress and decompress files on their way to and from the disk. However would there be any good reasons not to do this? In fact could I safely compress the whole of my %USERPROFILE% folder?

  • GZipped Images - Is It Worth?

    - by charlie
    Most image formats are already compressed. But in fact, if I take an image and compress it [gzipping it], and then I compare the compressed one to the uncompressed one, there is a difference in size, even though not such a dramatic difference. The question is: is it worth gzipping images? the content size flushed down to the client's browser will be smaller, but there will be some client overhead when de-gzipping it. Please advise.

  • Is there a way of leveling/compressing the sound system-wide?

    - by JethroDawnfine
    As a Laptop user, I'm sure that a lot of people, even the ones using Netbooks would have already gone through this problem. Especially when listening to podcasts, and using it as an example, the sound might have loud moments and quiet moments, one person speaking loud and the other speaking very quiet in the same episode. Thereby, I always wanted the sound to be compressed system-wide, and I just noted the other day, that in Windows, some Realtek drivers already offer this function. We have already a pulseaudio plugin for equalization system-wide, and although it still has problems like not letting us change its values and listen the change in real time, or cracking the sound while changing pulse volume, I do love it and use it. Now I'm just missing something to keep the sound around 0db (or near the volume level you're using) as a leveler plugin for pulseaudio. Any suggestion?

  • How to use Btrfs with compression on external USB hard drive?

    - by Andre
    I would like to make use of Btrfs' transparent compression on an external drive. Which tool is best for formatting the drive? Disk Utility or GParted? How do I activate the compression? During formatting or when I mount the drive? I guess at mount time. I'm using usbmount to automatically mount newly attached devices, because nobody is logged in on the desktop. Would I have to set general default options somewhere in a system configuration file to get Btrfs mounted with compression, or would I specify this via FS_MOUNTOPTIONS in /etc/usbmount/usbmount.conf and how? Thanks!

  • Snow Leopard Server, how to turn on compression for web

    - by gbrandt
    I am trying to make the webserver in Snow Leopard compress all output by default. The only thing I have found is to add SetOutputFilter DEFLATE in the .htaccess file for a directory. I really don't want to add an .htaccess file to every directory served. How can I globally get Apache2 on Snow Leopard to compress output?

  • On the fly volume compression (waveform capping) for VLC or OS X

    - by Grammar Nazi
    I'm looking to impose a hard limit on a movie. In particular when I have earbuds in and a reasonable volume set, loud or sudden sounds (gun shot, dramatic sound effects, gun fire, etc) are loud enough to hurt. Lowering the volume makes speech and other sounds hard to hear. Is there a third party on-the-fly solution for this, or a plug-in for VLC that I can use?

  • 7ZIP - Command Line Compression | Can Never Keep it Simple

    - by OneTwoYou
    I've been Googleing for a few hours on how to just compress a file inside a directory and I can't find anything. I found how to just compress a folder in general. Now I wish to know how I can compress a folder in a folder with a file. Current code: 7zG.exe a -tzip "test.zip" dontcompressme/compressme/new.txt pause As you can see above, I don't want to compress the first folder, but only the second and what ever is within that folder. I have the 7zG.exe sitting in the main folder and I have some files that are three folders in, but I don't know how to only compress those. Here is my directory list: Folder One (don't compress) Folder Two (don't compress) Folder Three (okay to compress) Document One.txt (okay to compress) Document Two.txt (okay to compress) Index.html (okay to compress) Does anyone know how I can do this in the most simplest way ever invented by man? Cause whenever I go to a website using Google it goes throw all these methods on how to compress a folder, but not do it the way I wish it to do. It makes me kinda upset cause I can't get a simple and straight forward answer. Thank you if you answer my question.

  • 7-Zip compression on multi-core computers

    - by Peter Mortensen
    Does 7-Zip take advantage of multiprocessor or multi-core systems when compressing? For example, would there be a close to 16 times speed-up on a 16 core system assuming no disk or memory bottlenecks? Or is it is limited to 2 threads (2 times speed-up on systems with more than one CPU or core)?

  • gzip compression good or bad?

    - by WarDoGG
    I have a server that currently does a lot of processing in my application and the target users are those who have a very good internet connection. The output that is sent from the server is always text/html and we do not use any media (audio/video) only images (static site images like logo,etc). We are experiencing severe performance issues and I wonder if turning off gzip/mod_deflate on the server so that the server would avoid compressing the output. Will this cause an improvement in performance?
