Free 3.x software for linux

FakeBold Font patches for QT 4.3.x fake a bold font style and output for some fonts without bold support.

It is specially and very useful for CJK fonts. actually it works with all fonts without bold style.

Here I use FT_Glyph_Embolden to get a bold glyph.

These patches is not related to font rendering result, if you want to control font rendering result, please control fontconfig configurations.

Screenshot1: shows bold/bolditalic support with "SOng" and "Hei" Chinese font.

Screenshot1: shows bold/italic support for Chinese,Korean,Yi,Tibetan with Sans fontset(Song,SIL Yi, Tibetan machine uni fonts)

Kayali is a Qt based Computer Algebra System (CAS) that can also be used as an advanced replacement for KDE KCalc.

Please Note: I am currently targetting a small subset of Maxima, while maintaining a medium-term goal of supporting all of Maxima. Please bear in mind that although Kayali probably does not support what you want to do with it right now, it can be made do so - but I need your feedback to do that. Please try it out if you can and share your thoughts.

Kayali is currently alpha software and has only been tested on my own PC. It you are reading this (condition1 : satisfied) and are prepared to give it a go, then please do send me feedback as to how you get on. At this stage I am particularly looking for hints about where to focus my development efforts, so please email me or post a message to the Kayali sourceforge forum with what you would like to see Kayali support.

I expect to see rapid development of Kayali so please check back regularly for updates.

Installation:

There is no real installation required. Simply untar the source tar.gz into a new directory. To run Kayali, type "python kayali.py" from the installation directory. Please note, however, the other required software packages. Of these, only Maxima and PyQt are mandatory. The others are only used for creating plots. If you are running linux then you probably have most of these already installed.

Algebra

Kayali supports all the algebraic operations of Maxima, however the graphical representation is not complete, though is being rapidly expanded. Please let me know what areas you would like to see finished first.

Try these for example:

eq1: 2*x + y = 13
eq2: x*y = 20
solve([eq1,eq2])

factor(x^6 - y^6)

factor(30!)

expand((2*x + y)^5)

Calculus

Kayali supports all the calculus operations of Maxima but again, I have only (so far) provided graphical support for a limited number of operations. Try these for example:

integrate(1/(1+x^3),x)

diff(3*x^4 - x^2,x)

Plots

Kayali currently uses Gnuplot for graphing. It also is using the Maxima interface to Gnuplot rather than addressing Gnuplot directly. This has both advantages and disadvantages.

Try this:

atan(-x^2+y^3/4) [Enter]

Then right-mouse click on the output in the table, and select Plot. Enter min and max values of -4 and 4, for both x and y. Select OK. After viewing the plot, click back on the History tab.

LinScope is GUI(QT), port scanner with enumerating windows network shares (SMB). LinScope can save favorites list. You can add different ip address ranges and scan them apart or together. Linscope searches FTP and HTTP services too.
LinScope project works in large networks and internet, where broadcast traffic is disabled(uses direct ip address and rpcclient from samba). User could manually assign command s for opening shares, apart for ftp,http and smb.
Installation:
1. From source linscope-X.X.X.tar.gz.
- You need gcc, make, QT 3.3.X(or later 3 series) with qmake, uic, moc.
- tar xvzf linscope-X.X.X.tar.gz
- cd LinScope/linscope/
- qmake
- make
Copy "lrpcscanip" and "linscope" to any directory existing in $PATH.
2. From binary linscope-X.X.X-bin.tar.gz.
- Unpack
- Copy "lrpcscanip" and "linscope" to any directory existing in $PATH.
Enhancements:
- "find" & "find next" now works
- changed ip addresses sort order in listview
- "add comment" now copyies previous comment
- "hide offline" action now available
- russian translation

KSystemLog is a system log viewer tool for KDE 3.3.x.
This program is developed for being used by beginner users, which dont know how to find information about their Linux system, and how the log files are in their computer.
But it is also designed for advanced users, who want to quickly see problems occuring on their server.
Main features:
- View all the main log of your system, by selecting them directly in a menu
- Auto display new lines logged in bold
- Tabbed view to allow displaying several logs at the same time
- Saving in a file and copying to clipboard the selected log lines are also implemented
- It can parse the following log files of your system :
- X.org (or Xfree) logs
- System logs (using the Syslog parser of KSystemLog)
- Kernel logs
- Daemons logs
- Cron logs
- Boot logs
- Authentication logs
- ACPID logs
- Cups logs (and embedded Web server)
Enhancements:
Major improvements :
- Improve a little bit the starting of KSystemLog.
- Add the Apache log.
- Add the Postfix log.
- Add the Samba log.
- Dialog box for sending log message manually from a dialog box.
- Log Toolbar is now visible by default, but only main logs are displayed.
- Colorize log lines by default.
Bug fixes / Minor features :
- Add a grayed "Type your filter here" in the filter (like Amarok).
- Remove shortcut on each log mode. They were to annoying to manage. The user always can bind the key he wants for a log.
- A double-click on an item opens the Detail Dialog.
- Fix a bug which decreased the log file reading.
- Add the Group By action to the Toolbar.
- Using sub-folders to sort source files
- Remove a useless space in most of logs
- Improve the saving of log views layout (column order is now saved)
- Remove tons of memory leaks
- Definetly fix the Detail Dialog by drawing it with Qt Designer

XNum project is a integer arithmetic library written in C++.
The difference between XNum and other libraries such as GMP is the the former tries to imitate the practical method that humans use to do the arithmetic themselves.
xnum implements the four basic operations (+, -, *, /) using the type of arithmetic we learned at school.
For example, to add two numbers
120
+14
---
134
This makes the code quite easy to read and understand.
C++ overloading techniques have been used so that the new data type, "XNumber", can be used naturally as the internal integer data types.
Enhancements:
- Updated to compile with less warning on gcc 3.x

QTVBA project is a graphical frontend to the VisualBoyAdvance Nintendo Gameboy Advance Emulator.
Main features:
- dual screenshot handling
- save game information
- number and last date played recording
- a built in ROM renamer
- compatibility with GBA-Shells screenshot formats and indexing

Health level 7 is a protocol that is used to allow medical computers from different vendors to communicate with each other.

HL7lib library is an attempt to produce a simple, correct HL7 library that can be embeded in projects to enable rapid development of powerful tools and robust interfaces. I intend to provide the same interface in C, Perl and Tcl. If someone else cares to implement the same library in another language (python perhaps) I will add a contrib section to this package and happily include it as well.

This implementation makes no attempt to implement grammar rules. I am a big believer in building a simple system that works and adding to it. I plan on keeping this version of the library stable and coming out with a seperate full featured 2.3x version as well as a seperate 3.x version. Those two versions will most likely be C/C++ only versions.
