Free ram software for linux

DBD::RAM is a DBI driver for files and data structures.

SYNOPSIS

use DBI;
my $dbh = DBI->connect(DBI:RAM:,usr,pwd,{RaiseError=>1});
$dbh->func({
table_name => my_phrases,
col_names => id,phrase,
data_type => PIPE,
data_source => [ ],
}, import );
print $dbh->selectcol_arrayref(qq[
SELECT phrase FROM my_phrases WHERE id = 1
])->[0];
__END__
1 | Hello, New World
2 | Some other Phrase

This sample creates a database table from data, uses SQL to make a selection from the database and prints out the results. While this table is in-memory only and uses pipe "delimited" formating, many other options are available including local and remote file access and many different data formats.

DBD::RAM allows you to import almost any type of Perl data structure into an in-memory table and then use DBI and SQL to access and modify it. It also allows direct access to almost any kind of file, supporting SQL manipulation of the file without converting the file out of its native format.

The module allows you to prototype a database without having an rdbms system or other database engine and can operate either with or without creating or reading disk files. If you do use disk files, they may, in most cases, either be local files or any remote file accessible via HTTP or FTP.

Booting Ubuntu To RAM is an article aims to document the process of creating a customized Ubuntu that loads an image from the hard disk to RAM, then boots an entire Ubuntu session out of RAM. It is intended for intermediate to advanced Ubuntu users who are familiar with the shell, and may have limited experience customizing the livecd (LiveCDCustomization) and shell scripting. We will customize a LiveCD and copy it to the hard drive, and make a few modifications to bootup scripts so that it copies to RAM via our good friend tmpfs.
WARNING: The author asserts that this procedure works for him, but cannot guarantee that this procedure works for anyone else. Although this procedure is meant to be 100% safe, it is feasible that there may be mistakes, or a chance of misunderstanding the instructions in a manner that causes loss of data. Please make a backup and do not attempt on mission critical systems. Read through this article thoroughly, and do not attempt if you do not comprehend or feel comfortable about any of the instructions!
CAUTION: I hope this is intuitively obvious, but Ill humor you and state it bluntly: Changes you make under the live session are NOT saved and WILL BE LOST when you reboot or shut down. Dont save anything important to the "home directory" and expect it to still be around! If you want to save data permanently, mount a permanent medium (such as your hard drive), plug in a thumbdrive, or use some network functionality built into Ubuntu to save your data to a non-volatile destination.
There are many cases where one would like to boot Ubuntu to RAM:
- Performance: The desktop performance is dramatically improved. A 400MB squashed filesystem in RAM, that holds 1200MB of data, is read back on a 1.6GHz Core Duo in about 3 seconds, including decompression time.
- Power, Noise, Durability: Although modern hard disks dont use much power compared to other system components, this may still be important for some. In laptops, hard disks are often the noisiest components, so this setup can reduce system noise. With the hard disk spun down, a laptop can potentially withstand greater shocks without damage.
- Abrupt poweroff: Since the hard disk is only momentarily used in read-only mode during boot, then never touched again, there are few or no negative consequences of an abrupt poweroff. If a system is used where power is inconsistent, or the system is regularly used in a context where fast shutoffs are required, this is very handy.
- Privacy: Anything you do in this session are lost when you reboot or power off. This is great for kiosks or other systems where permanent modification are not desired. (Note that by default the livecd user has full sudo access, so potentially a malicious user can still make permanent changes by mounting the hard drive and following this HOWTO)

ramrip is a little script which wraps up mplayer / ffmpeg. It downloads real video or real audio streams, and then encodes them. Video files are transcoded to mpeg format using ffmpeg. Audio-only streams can be encoded to ogg/vorbis, mp3 or wav formats.

Unlike ram2ogg, this script downloads uncompressed files first, then encodes them. Thus it is nicer to use ram2ogg for audio streams. This also means that you need A LOT of free disk space, since un-compressed video is HUGE!

Theres no manual page right now. Run the program with the -h option to see the following help:

Usage: ramrip [options] [basename]

Options:

-h : this cruft
-v : print name and version
-V : verbose mode
-d : dirty mode (dont delete intermediate files)
-a : audio format (ogg [default], mp3, wav)
-f : video format (mpeg [default])

EXAMPLES:

$ ramrip -f mpeg http://foo.com/video.ram wiggle
Downloads the URL, putting the result in "wiggle.mpg" (mpeg format)

$ ramrip http://foo.com/audio.ram
Downloads the URL, putting the result in audio.ogg (ogg/vorbis format)

$ ramrip -a mp3 http://foo.com/audio.ram
Downloads the URL, putting the result in audio.mp3 (mp3 format)

$ ramrip -a wav http://foo.com/audio.ram
Downloads the URL, putting the result in audio.wav (wav format)

karabass is my first karamba theme , just nice one, soory for my unpercfect english but its not so easy for a frog.

karabass is just system information(memory swap ram cpu fan eth0 houre amarok now playing..) i draw all part with the gimp.

Easy to modify it, i put in the compact file a empty background so if you dont like this one just draw yourself and rename this file...

On this desktop i just put liquidweather and meteosat them..

I use kubuntu 5.10 with kde 3.5

Streamsniff is a command line tool that sniffs network traffic for stream urls. I built it because I got tired chasing stream urls hidden behind loads of html and javascript.

Run it as root, fire up your browser and start the stream you want to "expose". Streamsniff detects the initiation of rtsp, mms, icy and http streams, and performs a backtrace on http traffic to detect "playlist"-urls (stream metafiles).

Sample output showing ICY, RTSP and MMS urls and their playlist urls:

ICY : http://212.92.28.98:2002/
: http://real1.radio.hu/BartokG2.ram

RTSP: rtsp://rmlivev8.bbc.net.uk:554/farm/*/ev7/live24/6music/live/6music_dsat_g2.ra
: http://www.bbc.co.uk/6music/ram/dsatg2.ram

MMS : mms://wm05.nm.cbc.ca/cbcr2-toronto
: http://origin.www.cbc.ca/mrl2/livemedia/cbcr2-toronto.asx

Streamsniff is experimental. It runs on little-endian (Intel/AMD), Linux and Windows XP SP2. I want to be less specific about the platform. Help with ports (big-endian, FreeBSD) is appreciated.

Detects:

MMS
RTSP
ICY
HTTP (with Content-Type: audio.. , video.. , ..wms-hdr..)

Komparator is an application that searches and synchronizes two directories. Komparator project discovers duplicate, newer or missing files and empty folders.
It works on local and some network / kioslave protocol folders (like smb:/ and media:/).
It is still in an early stage; please try on test directories first.

- Keyboard shortcuts (popup menus didnt work, unfortunately) fixed.
- Drag & drop missing / newer files from left to right side & vice versa.
- Special characters in URLs fixed.
- Cancel button isnt locked any more if md5-summing / binary comparing remote files.

- GUI cleanups.
- Resize list view columns to original width.
- Binary comparison wont store the complete file in RAM any more.
- First documentation attempt.
Enhancements:
- Filters to display only specific files
