I've tried to invent an exercise to take practice with lex.
Here is the result.
We can say that is more a micro-parser than a lexer.
It use a grammar to parse a simple tag language that describes a telephone memo and generate an html page to format it better.
It's just an exercise and you can download it at
Obviously GPLv3 licensed :)

Generic List [C]
Hi!
I've written a C code that implements a list usable with generic types.
To use this list you have to declare in an enum the types that you want to store in the list ad so you can arrive to generate mixed lists.
In the example I make tha case that you have a list with inside an int, a float and a struct Speed item.
If you want to use this generic list code you have to know that the code i really basic and not tested hard. Probably you have to extend him to your needs.
In the tar you will find also an example of using fully commented.
Enjoy!

in a post on my guestbook, jerry ask to me a way to make one.
My GB was just an experiment of php before I made the cms for my blog ( see ToyLog in the Software section)
A GB like mine is really basic so I post here only the source of the gbpost.php file.
POST FILE SOURCE CODE
You have to create the file post.php with this code personalized and the file Guestbook.txt containing an introduction where next the user comments follows.
The GB returns a mail with some info.
To see my GB you can go to CLICK HERE FOR MY GUESTBOOK

KSIP and Weblog update
Hi!
I've found the time yesterday to add to my weblog a feed RSS to make easier to control new posts.
The url of the rss feed is http://polystream.altervista.org/rss.php and you can control the feed, for example, directly with your browser (Firefox and Seamonkey natively support the feed reader) or by a dedicated software like akgregator (for KDE users) or shownews / newsbeuter (for console users).
The second update I've made is on KSlacky InfoPkg. I've released the test version of the 1.6.2 that improve the search and introduce the info button that calculate the total size of your slack packages and the biggest tgz in your system.
The test version is ready on the forum by clicking HERE
The tgz package of the 1.6.1 version are ready on the OFFICIAL SITE

Bliz Multifile Steganography System
I've written the specs for a steganography system.
With this specs you can build a steganography system that allow the user to encode/decode in an image up to 3 different ascii messages.
The steganography is an encryption system that insert datas to be hidden in an image, so you can preserve in your disk an innocent image that contains a message inside :)
The BMS2 (Bliz Multifile Steganography System) spec is released under the Creative commons licence.
You can download the spec here: DOWNLOAD BMS2 PAPER

Funny lisp code!
Hi!
Today I want to post a funny code... funny for me that I'm a lisp newbie.
Yesterday I'm starting learning lisp for pleasure.
Today in my strange brain jumps the idea to implement a mergesort.
I started the coding and all seems to be nice.
Since the last function where I take lots of strange behaviors.
The strange thing is that the program duplicate some numbers
{5,4,3,2,1} --a kind of-->{1,22,3333,4444,5}
Why?????
Let's change the method!
In the change I add some recursion to make this mergesort style
(setq M (round (/ I 2)))
(setq C (g_mergesort (g_firsthalf A M)))
(setq D (g_mergesort (g_secondhalf A M)))
(g_merge C D) )
but when I write the C assignment I launch a test with the previous mergesort system.
The code looks like this
(defun g_mergesort(A)
"The mergesort"
(setq I (list-length A))
;(print A)
(if (<= I 1) (return-from g_mergesort A))
(setq M (round (/ I 2)))
(setq C (g_mergesort (g_firsthalf A M))) ;blackbox
(g_merge (g_mergesort (g_firsthalf A M)) (g_mergesort (g_secondhalf A M))) )
It works o_O
but... in my mind not! I'm starting to write another way! this is a mix of the new and the previous code and it WORKS!!!!!
I looks to the recursion tree but scared I close it :D
This is the full code: LISP STRANGE MERGE SORT
enjoy!

Hi!
I'm pleased to release the first beta version of KSlacky InfoPkg.
KSIP is an information tool that shows information on packages installed on your Slackware and provide a GUI wrapper for package managment offered by pkgtool.

The program is still far to be complete, I have to correct the design of the user interface as suggested by alessiodf (www.slacky.eu community member).
Thanks to pinotree (#kde-devel-it user on irc.freenode.org) that explain to me a design concept to use ui files.
Thanks also to ksniffer (www.slacky.eu community member) that is my mentor in kde4 discovering ^_^
See you for next updates!
