Free detect software for linux

BPM Detect is a simple BPM detection utility.

Rogue Detect sends DHCPDISCOVER packets to the network and listens for DHCP servers to respond.

It can run continuously as a daemon, or do a single probe and quit. Its written in Perl and can be easily extended to take any action you can think of in response to an unknown DHCP server (send pages, disable them or whatever).

HTTP::BrowserDetect is a Perl module to determine the Web browser, version, and platform from an HTTP user agent string.

SYNOPSIS

use HTTP::BrowserDetect;

my $browser = new HTTP::BrowserDetect($user_agent_string);

# Detect operating system
if ($browser->windows) {
if ($browser->winnt) ...
if ($brorwser->win95) ...
}
print $browser->mac;

# Detect browser vendor and version
print $browser->netscape;
print $browser->ie;
if (browser->major(4)) {
if ($browser->minor() > .5) {
...
}
}
if ($browser->version() > 4) {
...;
}

# Process a different user agent string
$browser->user_agent($another_user_agent_string);

The HTTP::BrowserDetect object does a number of tests on an HTTP user agent string. The results of these tests are available via methods of the object.

ESTScan project is a program that can detect coding regions in DNA sequences, even if they are of low quality. ESTScan will also detect and correct sequencing errors that lead to frameshifts.
ESTScan is not a gene prediction program , nor is it an open reading frame detector. In fact, its strength lies in the fact that it does not require an open reading frame to detect a coding region. As a result, the program may miss a few translated amino acids at either the N or the C terminus, but will detect coding regions with high selectivity and sensitivity.
Method
ESTScan takes advantages of the bias in hexanucleotide usage found in coding regions relative to non-coding regions. This bias is formalized as an inhomogeneous 3-periodic fifth-order Hidden Markov Model (HMM). Additionally, the HMM of ESTScan has been extended to allows insertions and deletions when these improve the coding region statistics.
Enhancements:
- A bug has been found and fixed in the BTLib package.
- The bug prevented the extract_mRNA script from the estscan package from functioning properly when parsing RefSeq sequences.
- The prepare_data script has also been fixed to properly report the percent of masked nucleotides.
- All users preparing score matrices for ESTScan are strongly encouraged to update.
- Updating is less important for people who only scan sequences with already existing matrices.

Netmon is a console application that monitors network interfaces. It displays the transfer rate (upload and download) for each device and the data consumed by each device.
The main features of netmon are low resource usage, a simple yet effective design, and an easy to understand tabular output.
It displays values whose units change dynamically to scale with the value. Its compact display fits in a 9x66 size terminal window.
Enhancements:
- This release implements force units on totals and data rates, and updates the man page.
- The update functions now detect dev file overflow so that calling a function doesnt have to.
- The get_xxRate functions now detect a time limit of 0.
- Bugfixes for this version include a modified structure and library to extend data limit overflow to greater than 1000 terabytes.
- The configuration double digit bug was also fixed.

Whitespace is a Perl module to cleanup various types of bogus whitespace in source files.

SYNOPSIS

use Whitespace;

# Instantiate a whitespace object with
# both input and output files specified
$ws = new Whitespace($infile, $outfile);

# Instantiate a whitespace object with
# only the input files specified (in-place cleanup)
$ws2 = new Whitespace($infile);

# Detect the whitespaces
$ret = $ws->detect();

detect returns undef if it is unable to operate on the given file.

The error that caused the undef can be retrieved using error

print $ws->error() . "n" unless defined $ret;

detect returns the types of whitespaces detected as a hash which can be retrieved using the method status. The populated hash might look like this, if the file only had leading, trailing and end-of-line spaces (say on 3 lines).

%stat = %{$env->status()};
print map "$_ => $stat{$_}n", sort keys %stat;

eol => 3
indent => 0
leading => 1
spacetab => 0
trailing => 1

Cleanup can be achieved for all the whitespaces or for just a given type of whitespace, using the following methods.

If a outfile is given, the cleaned contents are written to this file. If not, the contents are replaced in-place. undef is returned if there was an error writing the file.

# To cleanup the all the whitespaces
$ret = $env->cleanup();

# To cleanup leading whitespaces only
$leadstat = $env->leadclean();

# To cleanup trailing whitespaces only
$trailstat = $env->trailclean();

# To cleanup indentation whitespaces only
$indentstat = $env->indentclean();

# To cleanup space-followed-by-tabs only
$sftstat = $env->spacetabclean();

# To cleanup end-of-line whitespaces only
$eolstat = $env->eolclean();

Image rotator can be used to automatically detect and rotate landscape/portrait photos from digital cameras.
Currently, only outdoor photos are recognized. Image rotator is a command line tool which uses an artifical neural network to detect the orientation of images. Image reading, scaling, and rotation are done with the ImageMagick library.
Enhancements:
- The --verify option can now be used to decrease the number of false decisions.
- This is done by running the image three times (original, rotated left, rotated right) through the neural network.
- A small memory leak was fixed.

Gnome Desktop Change is a daemon that changes randomly your GNOME desktop background.

Gnome Desktop Change is a daemon that changes randomly your GNOME desktop background. Its totally written in C++, it uses FAM (File Alteration Monitor) to detect changes into directory that contains picture files, and its multithread.
