Free why so serious software for linux

Chimera is an X/Athena Web client for UNIX-based workstations. If you do not know about the Web then try to grab a FAQ from rtfm.mit.edu using ftp. Chimera is not built on Motif so does not require this.
Installation:
See ./INSTALL for installation and configuration instructions.
See ./INSTALL.hints for tips on getting it to work in special cases.
What are all these files:
A description of the structure of the files in this distribution appears
near the end of this file.
Enhancements:
- Chimera 1.70 contains many new features compared to 1.65p1+1:
- 1) Table support has been vastly improved.
- 2) mailto:user@host URLs are now supported (via an external Perl script).
- 3) Display refresh has been substantially optimized.
- 4) Image handling improvements speed up rendering, a lot in some cases.
- 5) DNS caching cuts domain name lookup calls by about 90%.
- 6) Connection progress is displayed in the Title area.
- 7) The "Host:" HTTP request header has been added.
- 8) A new toggle button, DeferPix, has been added that turns delayed image loading on and off (or you can type i if you prefer).
- 9) If serious HTML command errors are encountered on a visited page, a small message saying so will appear at the bottom of the page.
-
- Chimera 1.70 also contains a long list of bug fixes, including these:
- Some 20 different memory leaks have been fixed, including all the major ones.
- Handling of excess "../"s in a relative URL has been fixed, and URL parsing in general has been greatly improved. The bug that a JPEG image in a file named *.gif would not only fail, but prevent ALL further image display has been fixed. A pages Title and URL are now restored in many cases where before they werent.

SLOOPS - Simple, Light, Object Oriented Persistence System.

SLOOPS is a lightweight Object Oriented persistence system.

If you want to follow the tutorial, uncompress the distribution from command line !

It has been designed with simplicity and reliability in mind. So you should expect:

- VERY EASY AND QUICK implementation of your own datamodel. - VERY EASY retrieving of your data. - Some limitations that are negligable for 90% of cases !

It has been tested in production environment for months, so you can relie on it !
It allows to make objects persistents with just a few lines of declarative code. It supports:

- Inheritance
- Class polymorphism.
- Scalar attributes ( can be Object ! )
- SQL Free queries !
- MySQL database ( other ones in the future ).
- Optionnal caching based on Cache::FastMemoryCache .

It doesnt support :

- nonscalar attributes. So you have to do helper objects to support n-n relations . Is it so bad ?
- transaction . Thats a serious issue. Will be implemented with other database support !

Sethi Search Utility provides a simple command line utility to submit a search to Google, Yahoo!, or MSN.
Sethi Search Utility is a simple command line utility to submit a search to Google, Yahoo!, or MSN and show the (text) results on standard output. Support for several search engines is included.
Its currently in serious need of a re-write, especially to avoid scraping and become a good engine using the search APIs provided.
Enhancements:
- The Google configuration was updated.

snowdrop provides a stenographic text/code watermarking tool.
snowdrop is a steganographic text document and C code watermarking tool that uses redundant, tamper-evident and modification-proof information embedded in the content itself, instead of the medium, to simplify tracking of proprietary code leaks, sensitive information disclosure, etc.
Snowdrop is intended to bring (relatively) invisible and modification-proof watermarking to a new realm of "source material" - written word and computer source codes.
The information is not being embedded in the least significant portions of some binary output, as it would be with a traditional low-level steganography, but into the source itself.
The idea, at least for English, isnt new - there was some serious work done by Mikhail Atallah from Purdue University. Snowdrop is merely an attempt to
provide a reliable, useful tool to implement those source-level watermarking / steganography capabilities. Because of some tricks, such as using specially crafted MD5 shortcuts, it gives certain additional advantages to its
potential users, such as integrity and privacy of embedded information, or an ability to demonstrate the origin of a document to the public (see section 2
for more details). Separate logical channels are used to carry highly redundant watermark to ensure it is extremely difficult to remove this information by accident, simple reformatting, etc.
Enhancements:
- Fixes an annoying bug that caused the code to segfault when there is no sync near the end of the watermarked file.
- Bit walk algorithm is still a bit broken, and the overall performance and storage capacity sucks, the code needs to be eventually rewritten.

PHP SQLDiff is a Web application that shows the difference between two SQL database tables.

If you manage your database tables like I do, you also make copious copies of the tables. When I go to make any serious change to a table, I copy the table to another database and make my changes there. In other cases my users make changes to their tables using SQLView. Of course, I keep backups of their tables elsewhere.

We know what we want, but its not always an easy thing to get. Here are a few things to keep in mind:

Just as with any diff, the more that changed, the harder it is to see what really happened. SQLDiff provides scrolled sets of changed rows, but any way you cut it, a million changes is beyond what anyone can reasonably manage.

The tables should have a primary key. SQLDiff does allow you to specify the column to use for the comparator. This means, however, that if your tables do not have the same primary key, then SQLDiff will not actually allow you to make changes. If you choose the wrong comparator column or the data for the column is not unique, you can serious mess up your tables.

The two tables must be basically the same. That is, they must have the same column names and the datatypes for the columns must match. SQLDiff can compare tables that do not have exactly the same columns, but youll have to choose what columns to compare. It will also pretend that columns of the same name, but with a different datatype are the same. This is not always true, so you should be particularly careful when making changes to unlike tables. In any case, the more the tables differ, the more differences are found until you can hardly figure out what happened.

Having said that, there are times when the change is that youve added or deleted a column or two. So SQLDiff will detect this and let you choose what columns you want to compare. In any case you still must have primary keys that match.

Really really large tables can take a really really long time to diff. In order to do the compare, we must read the entire table and that can be pretty hard on your systems. If youve got a few tens of thousands of rows, SQLDiff should be satisfactory, but if youve got a few million rows, well... good luck. Theres a good chance PHP will run out of memory and depending on your web server configuration, you might not get anything back so you can tell whats going on. In general you will not be happy when comparing really large tables.

Once the diff is known, you can make changes so certain (or all) rows or columns get updated in the master table from the modified table. Before actually commiting a database change, use the new Show SQL button and see if the SQL is reasonable.

Databases are seldom static and SQLDiff does not even pretend to protect you. If you do a diff on a pair of tables and one of then changes afterwards and then you try to synchronize them with SQLDiff... well, you could be surprised.

GNU Trueprint is a project which allows you to print source code.
Trueprint is a program for printing source code in a variety of languages (C is the best supported) and other text files to postscript printers.
It supports a wealth of options to support printing source code, such as diff-marking, line numbers, indentation levels, file and function indices, and many others.
The simplest way to compile this package is:
1. `cd to the directory containing the packages source code and type `./configure to configure the package for your system. If youre using `csh on an old version of System V, you might need to type `sh ./configure instead to prevent `csh from trying to execute `configure itself.
Running `configure takes awhile. While running, it prints some messages telling which features it is checking for.
2. Type `make to compile the package.
3. Optionally, type `make check to run any self-tests that come with the package.
4. Type `make install to install the programs and any data files and documentation.
Enhancements:
- Trueprint now uses autoconf and automake (Paul Smith, and the book GNU Autoconf, Automake and Libtool by Gary V. Vaughan et al, published by New Riders).
- Mention of trueprint.uu removed from README (Othmar Pasteka).
- Suffix .pike added for pike programs (Othmar Pasteka).
- Added include of sys/types.h before sys/stat.h to support FreeBSD (Dmitry Sivachenko).
- README.mswin removed (John Morey).
- If there isnt an lp or lpr command on your system when you run configure, trueprint will now be built to send postscript output to stdout by default (Othmar Pasteka).
- Choice options like --landscape and --option were broken due to a serious bug in options.c (Paul Smith).
- Added Canon LBP 3260 (Bjorn Wingman).
- Added HP Laserjet 1100 (Peter Green).
- Fix for handling arithmetic<<less
