Free what is ram software for linux

What is a Perl module to find out about running services.

SYNOPSIS

$what = What->new(
Host => my.domain.org,
Port => 28,
);

$what->mta;
$what->mta_version;
$what->mta_banner;

The What class is interface to classes providing information about running services. What::MTA is the only implementation so far.

What::MTA

MTAs supported are: Exim, Postfix (version only on localhost), Sendmail, Courier (name only), XMail, MasqMail.

See What::MTA for details.

METHODS

new

$obj = What->new( Host => "10.10.10.1", Port => 25 )

mta()

Returns the name of the MTA running.

mta_banner()

Returns the banner message.

mta_version()

Returns the MTA version.

nanoramba is a system monitoring SuperKaramba theme. microramba was still too much for me so it got nanomized. This is the result:
An even smaller theme to monitor your:
- cpu load
- used ram
- used swap
- incoming traffic
- outgoing traffic
Didnt need the exact values. Im fine with the bars.
Enhancements:
- top colored bars

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

hfishs monitor is based on this theme (http://www.kde-look.org/content/show.php?content=47852), I made some changes to best fit to my laptop.
Includes support for two cpus, two ethernet interfaces, ram, swap and two partitions, nvidia gpu temp.
Enhancements:
- Added nVidia GPU temp support

ariane project is a bootable CD-ROM linux. Its the successor of giotto. While giotto booted a libc5 system with a linux kernel 2.0.37 from floppy disks, ariane comes with linux kernel 2.4.26 and libc6, version 2.2.4.

It boots (just as giotto) into your computers RAM. After its up and running you can remove the CD-ROM for something else. ariane does neither have to be installed on a harddisk nor does it use a live-filesystem on the CD.

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..)

ftRTOS is another free and small realtime kernel for microcontrollers focused on minimal RAM usage. The "ft" prefix means femto, the next order after nano and pico.
Primarily this kernel is intended for MSP430 family of microcontrollers. Porting to another architectures is quite simple but on some architectures performance may degrade.
The source code is written in pure C. The preference is given to GCC as free software should be compiled with a free compiler. Assembly language is used only where it is unavoidable.
Main features:
- Minimal use of RAM. For example, on MSP430 in minimalistic configuration it is required only 6 bytes of RAM per task not including stack.
- Static definition of tasks and protected shared objects.
- Multiple levels of priority, fixed priority scheduling. By design, the number of levels is limited by the maximum number that unsigned char data type can hold.
- Preemptive or cooperative scheduling policy.
- Unlimited number of tasks by design.
- No idle task.
- Simplicity and clarity as a design philosophy.
Two approaches are used to achieve the main design goal: avoiding dynamic memory management and splitting all structures into two parts.
Dynamic memory management adds overhead to all memory blocks and requires some additional code. Without dynamic memory management it is impossible to dynamically create tasks and synchronization objects (more precisely, protected shared objects, PSO). But for tiny systems it is not a key feature. So, all tasks and PSOs are defined at compile time.
Splitting structures that describe tasks and PSO means that they have constant (ROMable) and variable parts. The first one contains static properties, such as priority, address of entry point, address of stack, etc. The variable part is placed in RAM and contains only those properties that require changes at run time.
It is necessary to note that such division requires frequent access to the flash/ROM and on some architectures it may lead to performance degradation. For example in AVR family the access to the flash memory is very painful.
The simplicity of kernel as a design philosophy obliges to implement only minimal set of functions and only those which are absolutely necessary. Theres only one global critical section which disables context switching. There are no functions to suspend and resume tasks (their appearance in user code tells that something wrong in software design). Only one type of PSO, namely queue, is used for communications between tasks.
However, sticking to minimalistic design leads to inflexibility. Therefore in addition to minimalistic design a list-based design has been implemented. The user can choose either. The differences and features will be explained later. Generally, list-based design increases the size of variable part of task structure (on MSP430 it becomes 12 bytes) but allows several waiting tasks on each side of PSO, the priority inversion problem is handled (the users choice) and other types of PSO may be implemented.
