Performous 0.3.1
A free Linux karaoke game more>>
Performous 0.3.1 is created to be a karaoke program that can both display the lyrics, notes but also display how well you actually hit the notes. Unlike in many other games in this genre, you will also see the pitch that you are singing, so that you can see what you are doing wrong and easily (well, everything is relative) correct your pitch.
Most of the songs available also contain the original vocals and actual karaoke versions are rare.How it works? The game records your voice via a microphone, attached to your computer. The audio is recorded and realtime FFT analysis is done on it. This analysis reveals which frequency bands contain audio (peaks).
Further analysis is used to find out the exact audio frequencies inside each band, and to combine base frequencies and their harmonics into single tones. Finally, some temporal (over time) filtering is applied to the detected tones to smooth out the output. It doesn't matter if you didn't take university courses on acoustics and mathematics, and none of that makes any sense: you will get a wave on screen, displaying your singing pitch.
Scoring and note types
- Regular notes: displayed in light blue (1x points)
- Golden notes: displayed in gold (2x points)
- Freestyle notes: displayed in green, pitch does not matter (1x points)
The singing octave does not matter, so as long as you get the right note in any octave, you will get full points. Singing near the correct note also gives some points, but the amount of points per second decreases as you get farther from the right tone. Singing within the right semitone always gives full points, so you may actually be off by a quarter tone and still get the points.
The maximum number of points is always 10000, but it is practically unreachable in real songs, usual scores being in the range of 2000-9000, depending mostly on the skills of the singer, but also on the song: even though the maximum is the same, slower songs are generally easier to sing.
Oh, and in case you were wondering: you will not get full points by placing the microphone near a speaker, because it will also pick up other instruments, which usually have incorrect pitch. Expect to get about 3000 points with this method.

<<lessNetwork-I 1.4.0
Captures, displays and analyses TCP/IP traffic more>> Network-I comprises a fast sniffer with a powerful filtering language, and a suite of tools to process the captured packets.
The possibilities range from the straightforward display of packets in exhaustive detail (or alternatively, in a 1-line summary mode) to measurement of traffic levels, and reporting on packet retransmission and losses.
It can also import (and export) capture files in tcpdump and snoop formats.
Network-I is therefore ideal for a troubleshooting network admin, and developers who want to debug the network traffic exchanged by their applications - or even for the curious student of networking who wants to look under the hood of TCP/IP.
This program is distributed as a set of pre-built Linux and Solaris packages, for ease of installation (and uninstallation).<<less

JSizer 1.1
JSizer project is a tool that shows java code size. more>>
JSizer reads in a set of jar files and then draws a graph of the current state of the code. The graph has nodes in it and the nodes get their color and size depending on a few things.
- Green nodes are packages
- Grey nodes are classes
The class nodes get their size and color from:
- Width represents the number of fields in the class
- Height represents the number of methods in the class
- Color represents the number of lines of code in the class, a dark node has more lines of code than a light node.
What you want to do is to look at the graph, find the big dark boxes and possibly refactor them.

JumpBox vTiger CRM 1.0
JumpBox vTiger CRM is a JumpBox virtual appliance with a pre-configured installation of the vTiger CRM system. more>>
Once upon a time, in the raw and exciting days when automobile technology was in its infancy, taking a road trip meant bringing a mechanic along to fix the car every time it broke down. At JumpBox we look at the current state of IT systems and see great similarity with the early automobile.
Today, if you want to deploy and run a server based application you need a mechanic to come along to keep it running. With the automobile, as time passed, the technology improved, cars became vastly more reliable and many more people were able to take to the road.
With JumpBox we’re looking to do the same for server based software. We simplify what has traditionally been complex and deliver server based Open Source applications to an audience that otherwise would be put off by the technical burdens of the old way of doing things.
An integrated software stack in a virtual appliance
A JumpBox bundles the operating system, application and all application dependancies into a single installable module that’s easily deployed using virtualization software from VMWare, Parallels or Xen
Easy to Install
A JumpBox allows you to install a complex server based application without having to know anything about Linux, databases or the command line. You just download, extract the archive and open the application with your virtualization software. Further setup and configuration is handled through a simple web interface.
Simple to manage
The JumpBox platform is pre-configured, tuned and secured to minimize the management needs of the application.
Runs anywhere
Mac OS X, Linux, Windows it doesn’t matter. Thanks to the use of virtualization, JumpBox applications run easily on all the most popular operating systems.
Painless to upgrade
With a JumpBox and the JumpBox Assurance program (launching Q2 2007), management of the system is simple and efficient. Updates to the entire software stack are handled automatically by the platform with minimal user interaction.
Quick to move
With a JumpBox all the application code, data and the runtime are bundled together into a single directory that can easily be moved between systems or even across platforms. This allows you to start using an application by just running it on your desktop. Then when you’re ready you can open it up to the rest of the network and either continue running it on your desktop or easily move it to the server at any time. It doesn’t even matter if the server is running a different operating system, with a JumpBox everything is self contained.
Libnids 1.22
Libnids is an implementation of an E-component of Network Intrusion Detection System. more>>
The most valuable feature of libnids is reliability. A number of tests were conducted, which proved that libnids predicts behaviour of protected Linux hosts as closely as possible.
Libnids is highly configurable in run-time and offers a convenient interface. Currently it compiles on Linux, *BSD and Solaris. WIN32 port is mantained separately here.
Using libnids, one has got a convinient access to data carried by a TCP stream, no matter how artfully obscured by an attacker.
Enhancements:
- in TCP stream, the byte with absolute offset 0 was treated as urgent data; fixed
- DLT_IEEE802_11_RADIO handling
- added a few missing checks for failed malloc
