Netstation is a Linux distribution that enables you to convert standard PCs into full-featured diskless thin clients supporting all major connectivity protocols. The project can be booted from the network using Etherboot/PXE or from standard media like floppy/CD/hd/flash-disk etc. The configuration is centralized to simplify terminal management.
Terminal protocols supported
- X-Terminal XDM
- TightVNC
- SSH
- Telnet
- Rdesktop RDP
- Citrix ICA
- Tarantella
Boot methods
- DHCP/TFTP with Etherboot or PXE bootrom
- From floppy, hard disk, cdrom or DOC2000 using Syslinux
- From DOS using Loadlin
GUI modes
- Single client in fullscreen session
- Text session (Telnet or SSH)
- Multiple concurrent clients using local window manager
Other features
- Local printer support through network printer emualtion
- Network card, video card and mouse autodetection
- Dynamic ".nsp" package support (can be loaded at run time)
- Centralized configuration using TFTP to obtain config files"

ost is a simple yet powerful tool providing mechanisms to automatically audit, maintain and backup systems customizations. ost is particularly well suited to environments where most systems are similarly configured, but will operate just as well if each system is unique.
ost uses at least one of the following two sets of input:
- the systems file catalog if it exists
- user defined "templates" to override the systems catalog
These allow ost to build a virtual image of what the local filesystem is supposed to look like. This image is then compared to the actual state of the local filesystem to obtain the following information about the system:
- List of intact files
- List of modified files
- List of missing files
- List of additional files

mod_cdb obtains the contents from a cdb file.

It is suitable for handling thousands of small files.

BUILD:

1. Get djbs cdb package from http://cr.yp.to/cdb.html
2. Extract and build it.
3. Edit ./Makefile to make it point the Apache installed directory and the cdb directory (I suppose cdb-0.75).
4. $ make install

USE:

Add this to the httpd.conf:

LoadModule cdb_module modules/mod_cdb.so
< Location /path1 >
SetHandler cdb
CDBSource /somewhere/data1.cdb text/html
< /Location >

When URI http://yourhost/path1/abc is accessed, the server tries to obtain the contents from the cdb file /somewhere/data1.cdb by the key "abc", with the predefined mimetype "text/html".

Statistics::Contingency is a Perl module to calculate precision, recall, F1, accuracy, etc.

SYNOPSIS

use Statistics::Contingency;
my $s = new Statistics::Contingency(categories => @all_categories);

while (...something...) {
...
$s->add_result($assigned_categories, $correct_categories);
}

print "Micro F1: ", $s->micro_F1, "n"; # Access a single statistic
print $s->stats_table; # Show several stats in table form

The Statistics::Contingency class helps you calculate several useful statistical measures based on 2x2 "contingency tables". I use these measures to help judge the results of automatic text categorization experiments, but they are useful in other situations as well.

The general usage flow is to tally a whole bunch of results in the Statistics::Contingency object, then query that object to obtain the measures you are interested in. When all results have been collected, you can get a report on accuracy, precision, recall, F1, and so on, with both macro-averaging and micro-averaging over categories.

Meteosat is a SuperKaramba theme that integrate latest meteosat image in the desktop.

The fetched image is processed by imagemagick (required), to obtain a "soft start border", through png opacity.
