Free come and go software for linux

Qgonki is a small tool for converting Polish letters between severals standards, like ISO-8859-2, Windows-1250, and others.

Its useful for Polish webmasters who want to go with the world standards, but whose contributors are stuck in Windows.

This software is used for the automatic probing of internet hosts at a timed interval (reconnaisance), checking host connectivity, especially ICMP support (information Gathering), automated running of third party tools when said host is online (automated testing).
Use of sonar shifts responsibility for the users actions solely to that user him or herself. In other words, the author cannot be held responsible for your actions.
Examples
Run nmap with a vanilla connect scan as soon as www.google.com is online. Check every 60 seconds, go into background, and log to probe.log:
sonar -c -1 --scan_delay=60 -f --output_plugin=L
-p fprobe.log -pe"nmap -sT www.google.com"
-sI www.google.com
Check red0xs site for online status 4 time in a row (just like ping):
sonar -sI genbukan.no-ip.com
Send the contents of payload.dat to www.secursite.com every 5 minutes:
sonar -c -1 --scan_delay=300 -p ppayload.dat -sI
www.secursite.com
Send an ACK probe to googles webserver every second.
sonar --scan_delay=1 -c -1 -sA www.google.com -pp80
Enhancements:
- src/mutex.h, src/plugin.h, src/types.h, libltdl/configure, plugins/network_icmp.h, doc/Makefile.in, Makefile.in, doc/Makefile.am: Major documentation update, more to come.
- plugins/rfc793.h, plugins/rfc793.c: Removed the bloody thread (which was causing so many problems) from the ack scan

Volumevis displays pixel-based 3-dimensional datasets. 3-D pixel datasets mostly come from 3-D computer tomography (CT) and magnetic resonance (MR) images. These datasets usually come in the form of a set of 2-D picture files each being a slice of the 3D dataset.
To be displayed by volumevis, the files have to be ordered with identical names except for a number somwhere in the name corresponding to the slice number. Most image formats (jpg, tiff, dicom, etc ..) are supported.
Volumevis is a tool for visualizing 3D dimensional pixel-based datasets. Most computer 3D visualization in the world is with surfaced-based visualization. This is true for most 3D games, CAD tool, etc.
By stating it simply, surface-based rendering works by dividing a predefined surface into small triangles, and then sending those triangles along with their color to graphicscard to be rendered. For example,if you want to render a sphere in 3D, you would create a surface of the sphere, divide it into triangles, send the triangles to the graphics card, which would then turn the triangles into pixels and displaythem.
The unfortunate side-effect of this is, that if you happen to cut the sphere, or go inside it, you will see that its in fact hollow. Also, you cannot see any of the details that might be inside of the sphere.
Volume visualization is the equivalent in 3D of displaying a photo in 2D. The surface 3D visualizations on the other hand, are the equivalent of reducing a photo to a representation of lines (such as the outlines of people and houses) and drawing the lines on screen. Obviously a lot of information goes lost in the line representation.
The visualization works like this. In openGL (a graphics programming API), all fragments (3D equivalent of pixels) have an alpha value. The alpha value corresponds to the opacity of the fragment. If the fragment has a small alpha value, it will be easy to see through it and see the fragments behind it.
If the alpha value is high, the fragments behind it will be obscured. A 3D dataset is simply a block of data in the shape of a cube. Somewhere in the image there is an object which is white or grey. All the other places in the image are black. To render the object, all the pixels which are black are assigned and alpha value of 0 (meaning they are transparent). Therefore we dont see the black pixels.
The fragments belonging to the object are white and have an alpha value higher than zero. Therefore its not possible to see through them, and we perceive the location of the object fragment to be the surface of the object. Depending on the alpha value of the fragment, we might also be able to see some of the fragments behind it a bit (see inside the object).
At the moment, Volumevis only supports black/white images (which is fine for most CT and MRI datasets).
Enhancements:
- A bug with slice loading of textures which are not a power of two was fixed.
- Movie recording, cropping, and file saving for slices were fixed.
- Various feature improvements were made.

Oggasm is a program that makes converting your mp3 collection into oggs a all but painless process.

Using oggenc and mpg321, with perl glueing it all together, oggasm is able to go through an entire collection, identify id3 tags and then convert those mp3s into oggs while keeping the id3 tags intact.

TODO:

server-client model: When oggasm is started I want it to creat a list of jobs that need to be done and then assign those jobs to various clients that could either be running on the same machine or on other machines connected via a network.

Im of two minds on how to do this. Either I learn how to use sockets and develop my own communication protocol to tell the clients what to do, or I create physical files that are grabed by the client via ftp or samba. Each one has its advantages and disadvantages and I hope to look into it more soon.

One thing that is very important is that a client machines need to be able to come and go as necessary. So oggasm might start with 2 clients, be at 5 later in the day, and then down to 1 when it all finishes.

network functionality: How this will look will rest largly on how the server-client model ends up looking. But most likely the it will involve using ftp or samba to grab files from the server machine, convert them, and then send them back to the server. After that the
client will be assigned a new job.

improvments to user interface: This will be a on going process. As I continue to get more feedback on how people felt their experience with oggasm was I can improve how it the interface looks. Recent changes with 1.3 will allow updates to the interface to be much smother than before.

more encoder/decoder options: certainly oggenc will remain the primary encoder, however other free codecs might come along someday, and it would be nice if oggasm was modular enough to beable to plug in different encoders. I would also like to support different decoders as not everyone has mpg321 (however I will NOT provide support of non-free decoders).

OO Learning Evaluation GO is an object-oriented platform and algorithms for the game of GO.
It aims to provide a capable engine that can learn through experience and a re-usable algorithmic framework for the rapid development of new GO-playing engines.
Enhancements:
- Reorganization of the code was started so that various learnable evaluation functions can be used easily.
- Learning is currently tested in the GoPlayer module.
- The learned function simply learns to imitate the current static function.

The normal desktop calculators seem counter-intuitive to me. Why emulate the limited interface (ie a numeric pad) of a pocket calculator, when youve got the power of a desktop computer and keyboard at your finger tips.

SuperKaramba Calculator is a very simple calculator theme, with a lot of hidden power. It uses the google calculator as its engine, which means that it can do complex calculations from a very simple interface. If the calculation is a simple mathematical expression, the theme will use the bc program, rather than going online. It does unit conversions and currency conversions as well.

You can enter an equation in mathematical notation, or in everyday language. For example:

four plus five
4+5
2000 kilometers per hour in feet per year

The theme stores the last 10 queries, so that you can go back over them.

The theme checks for invalid characters, and parentheses mismatches.

The theme also allows you to use the keyword "ans" in your query, which will substitute the last result into your current query. This could save typing a lot of text if youre chaining queries together.

How to use it ...

This is so simple to use, it doesnt really need a manual. The theme consists of three elements. A text entry box, a text display and a button.

To run a calculation, put your query in the text box. Then left click the button. The theme will go off and do its magic, and come back with an answer that will be displayed as text underneath the text box.

Sometimes what you enter may not be able to be processed, either because youve typed it wrong, or it doesnt understand you, or because youre asking it to do too much. If that is the case, then the theme will tell you.

To access previous queries, middle click on the button, and select the relevant query from the dropdown list.

mod_removeip is an Apache module that can remove information about the remote IP.

This module throws away the information on the remote IP and hostname right at the beginning of handling the request. That means its not logged, is not available to any web apps, and cant leak into error logs and the like.

This is written for use on servers with a strict policy on protecting the identity of their users. If the Spooks come and demand that you hand over your server so they can try to identify one of your users, this should be enough that you can categorically state that there is no IP info to be found, and might mean your server doesnt go offline.

There is currently no facility for enabling the module on a per site or per directory basis. Its an all or nothing thing. This is because the intent is to make sure IP info is not on the server at all. If people want more configurability, I might release an
alternative version.
