Free production possibility curve software for linux

owl is a program to display electronic dictionaries. It uses the extensive markup language dicML.
Two dictionaries are currently available with this program: a huge English/German dictionary originally published by Technical University of Chemnitz, and a French/German dictionary written from scratch for dicML and therefore not as big as the first one.
Main features:
- support of the whole dicML standard
- available for all important operating systems
- user interface in English, German and French
- possibility to print
- for free and open source

File Activity Viewer opens a file and shows you the last lines (this is configurable) and then keeps waiting for changes in that file.
It works like a graphical (with GUI) tail -f.
Enhancements:
- Add Edit menu with Copy, Clear and Select All functions.
- Add possibility to open multiple files at once in the same window

mysqlrowcopy is a tool that generates insert statements from result sets. It produces output similar to what might result from running mysqldump on a single SELECT query.

This project helps eliminate some of the tedium of moving data between QA and production MySQL databases.

Build:

To build mysqlrowcopy, you should run:

./configure
make

A mysqlrowcopy and mysqlrowcopy.debug file are created. They have identical functionality, the .debug version simply has debugging symbols built in (for gdb).

Since mysqlrowcopy is probably going to be I/O bound with modest CPU and RAM usage, the only reason to even build a 64-bit version is to work around potential issues in dynamic linking 32-bit binaries against 64-bit libraries.

RECIPES

1. Migrating a MySQL user account reaper from QA server to a production server.

e.g. MySQL database server qa3.example.com to prod1.example.com:

$ mysqlrowcopy -h qa3.example.com
SELECT * FROM db WHERE User = "reaper" mysql db > reaper.sql
$ mysql -h prod1.example.com mysql < reaper.sql

You could of course simply pipe the output of mysqlrowcopy into mysql and skip the intermediate file.

(Dont forget to RELOAD PRIVILEGES afterwards)

2. Keep your test environment up to date. Populate it with production data every 24 hours. You could run this sequence from cron once a day:

$ mysqlrowcopy -h finance-db.example.com
SELECT * FROM stocks WHERE modified > DATE_SUB(NOW(),INTERVAL 24 HOUR)
finance stocks > day-stocks.sql

$ cat day-stocks.sql | mysql -h finance-test.example.com finance

3. Copy data between tables on different servers that have some similar fields.

Youve got common data in table Zip on a production database:

mysql> desc Zip;
+-------------+-------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------------+-------------+------+-----+---------+-------+
| ZIPCode | varchar(5) | | PRI | | |
| ZIPCodeType | char(1) | YES | | NULL | |
| City | varchar(32) | YES | | NULL | |
| CityType | char(1) | YES | | NULL | |
| State | varchar(32) | YES | | NULL | |
| StateCode | char(3) | YES | | NULL | |
| AreaCode | char(3) | YES | | NULL | |
| Latitude | varchar(12) | YES | | NULL | |
| Longitude | varchar(12) | YES | | NULL | |
+-------------+-------------+------+-----+---------+-------+
9 rows in set (0.00 sec)

And youve got table ZipPosition in a research database:

mysql> desc ZipPosition;
+-------------+-------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------------+-------------+------+-----+---------+-------+
| ZIPCode | varchar(5) | | | | |
| Latitude | varchar(12) | YES | | NULL | |
| Longitude | varchar(12) | YES | | NULL | |
+-------------+-------------+------+-----+---------+-------+
3 rows in set (0.00 sec)

You want to load data from production Zip into research ZipPosition.

$ mysqlrowcopy -h production SELECT ZIPCode,Latitude,Longitude common ZipPosition > pos.sql
$ cat pos.sql | mysql -h qa research

Note how we specify ZipPosition on the first line to tell mysqlrowcopy what the destination table is going to be.

C++ Elliptic Curve Cryptography library is a C++ library for elliptic curves cryptography.
Libecc is a C++ elliptic curve cryptography library that supports fixed-size keys for maximum speed.
The goal of this project is to become the first free Open Source library providing the means to generate safe elliptic curves, and to provide an important source of information for anyone with general interest in ECC.
Enhancements:
- This version brings the code completely up to date again with the latest of version of the working set (autoconf, compiler, etc.).
- The previous version was almost two years old and didnt even compile anymore.

conn-close gives us possibility to get rid of entries in ip_conntrack about ESTABLISHED TCP connections that goes through our server.

conn-close script uses hping2 to send spoofed RST packets which will fool conntrack and cause specified connections to be considered by conntrack as closed (now these connections will be in ip_conntrack in CLOSE state), even though RST packets will be more likely discarded by destination host.

Information about connections is read of course from /proc/net/ip_conntrack.

Idea was taken from script seen somewhere on the internet.

BBCNews.co.uk RSS reader is a SuperKaramba theme.

Based on LTRSS reader (http://www.kde-look.org/content/show.php?content=27639) I really didnt do almost anything to the original script, just changed things to BBC and made the header pic.

I just thought that since i did it i might as well post it here.

CrunzhMonitor is a small program to check the stability of your web server. It simply checks the possibility of connecting to you web server (http server) and if it fails, maintains a error log.

It is possible to configure how often it should check.
CrunzhMonitor is released as open source software under the BSD license.

seccure toolset implements a selection of asymmetric algorithms based on elliptic curve cryptography (ECC). In particular it offers public key encryption / decryption and signature generation / verification.
ECC schemes offer a much better key size to security ratio than classical systems (RSA, DSA). Keys are short enough to make direct specification of keys on the command line possible (sometimes this is more convenient than the management of PGP-like key rings).
seccure builds on this feature and therefore is the tool of choice whenever lightweight asymmetric cryptography -- independent of key servers, revocation certificates, the Web of Trust or even configuration files -- is required.
Where can I download seccure?
seccure is GPL software. First download seccure from the following link. Then, after having made sure that libgcrypt is properly installed, run make and make install as usual.
How is seccure used?
First we give an example for key generation:
$ seccure-key
Assuming curve p160.
Enter private key: my private key
The public key is: 8W;>i^H0qi|J&$coR5MFpR*Vn
Then we do some public key encryption / decryption:
$ seccure-encrypt -o private.msg 8W;>i^H0qi|J&$coR5MFpR*Vn
Assuming MAC length of 80 bits.
Go ahead and type your message ...
This is a very very secret message!
^D
$ seccure-decrypt -i private.msg
Assuming MAC length of 80 bits.
Assuming curve p160.
Enter private key: my private key
This is a very very secret message!
Integrity check successful, message unforged!
At last we try out the signature generation / verification:
$ seccure-sign
Assuming curve p160.
Enter private key: my private key
Go ahead and type your message ...
This message will be signed
^D
Signature: !JI1%Luh6mu:@)S3wS.go(u1z,b.NhXIUI)/p@$*ONA+)+G}}_
$ seccure-verify 8W;>i^H0qi|J&$coR5MFpR*Vn !JI1%Luh6mu:@)S3wS.go(u1z,b.NhXIUI)/p@$*ONA+)+G}}_
Go ahead and type your message ...
This message will be signed
^D
Signature successfully verified!
Enhancements:
- This release adds signcryption and inline signatures.
