PICMe in Linux
And now the PICMe OpenGL version ,
Objectives:
To port PICMe (Windows) Downloader into Linux Downloader
To enhance the use of PICMe in Linux OS platform
Requirements:
qt
gtk
kde
gb.net
Methodology:
Detail(1)Fedorra 13 with Gambas IDE(Visual Basic for Linux)
Detail(2)PICMe linux opening the code
Detail(3) PICMe linux executing the downloader
Detail(4)PICMe linux executing its serial monitor
Detail(5)PICMe-linux showing its loading with progress bar
Remarks:
It is quite laborious but offering it for free somehow relieves fatigue in burning eyebrows and that my hair is decompressing-(Oh,come on go to R&D)
Conclusions:
PICME for Linux is now available

Optical Character Recognitions (Gambas2 & Tesseract/OCROpus)
Introductions:
Basically , this blog is just a complementary to my project "Robo-Book Scanner" and what we will be discussing here are: the main software that will make it easier to use OCR's engine (Tesseract or OCROpus) as a back end applications.And by using Gambas version(VB for Linux) which has an advantage featured of designing front end GUI.
To make it short ,we need to come across of how we can use Gambas 2 & Tesseract to work one application together ,and for us to see how each would give an excellent results as Robo-Book Scanner software which is an OepnGL release OCR software tool.So, our intentions is to use Gambas as IDE /GUI for OCR and its engine no other than- Tesseract or OCROpus.
The last one , is to give you a brief an idea technically
1) We need to hack Tesseract engines, i have read some articles "Hacking Tesseract V0.04" and this is the website - http://tesseract-ocr.repairfaq.org/ and if we could combine testing OCROpus which documentations can be found here -http://code.google.com/p/ocropus/wiki/InstallTranscript well that is better!
2) We need to study Gambas interfacing with C/C++ specially their shared libraries in the Linux Kernel. "How To Program Components In C/C++" and this website -http://gambasdoc.org/help/dev/overview
3) How we open image file in Gambas version 2 (esp: *.TIFF,JPEG,BMP ) and other available free "pdf"converter ;in this website - http://gamblis.com/2009/08/08/sharpdevelop-tutorial-how-to-rotate-an-image/

Requirements:
g++scons
svn
libpng12-dev
libjpeg62-dev
libtiff4-dev
libavcodec-dev
libavformat-dev
libsdl-gfx1.2-dev
libsdl-image1.2-dev
Methodology:
Installing iuLib
Download iulib 0.3 package from iulib's google code page. http://code.google.com/p/iulib/Get any missing libraries, run: sudo apt-get install libpng12-dev libjpeg62-dev libtiff4-dev libavcodec-dev libavformat-dev libsdl-gfx1.2-dev libsdl-image1.2-dev
if you get errors downloading any of these libraries, change your package download server. See the note at the top of this document.
Run: sudo scons install (This will help avoid an error in the next step. Make sure to have scons installed.)
Run: sudo make install
Installing Tesseract
svn co http://tesseract-ocr.googlecode.com/svn/trunk/ tesseract-ocr
cd tesseract-ocr
./configure
make
sudo make install
Install OCROpus
# pick one of the following
release="-r ocropus-0.4.4" # this selects release 0.4.4

Pointer (Coding skills & technique)
Interlude:
main()
{
initialise :
MCU
ENC28j60
tweaking the TX/RX between the two interface
detect for a raw packet then send back to it.
}
Let's take a scrutinizations to these:
Pointers and Constants:
Given the following:
char buffer[100];
char name[20];
//pointer to const char
const char *p = buffer;
p = name; // ok
*p = ’x’; // error!
//const pointer to char
char * const p = buffer
*p = ’x’; // ok
p = name; // error!
const char space = ’ ’;
const char *p = &space; // ok
char *q = &space; // error!

GAMBAS (Opensource Visual Basic)
Introductions:
If we are going to review its predecessor we will find out that its origin is basic for dos to its latest versions until then enhanced to VB for dos (GUI running in Dos). Then later that development came the VB 5-6 (final version was until 1998) up to the designated successor -VB.net.
No wonder ,Gambas was inspired by VB programming ingenuity and intended to provide a similar experience for developing BASIC programs to Visual Basic. Gambas is intended to be an alternative for former Visual Basic developers who have decided to migrate to Linux or Unix like OS.
So Kudos! to VB and its migration in Linux-Gambas.
Objectives:
To be familiar with Gambas
To adapt Gambas with previous VB6 knowledge back ground
To create a simple sample program in Gambas
To use Gambas in MCU embedded support programs.
Methodology:
Detail(1) : sudo apt-get install

The Big Four(Assembler,Basic,Pascal and C/C++)
It was my first year in highschool when we had an informal orientation of learning a basic computer concepts it was then that I experienced operating a computer - an 8086 AT IBM computer(atlast ! the real keyboard not a dashboard drawing).Fresh from my memory as I was able to remember those weird techy things, I took my first programming lesson way back our third year in highschool. Well, we're a little bit fortunate because our school was supervised by an Italian priesthood(Sumascan order ) and the technology that they had were unselfishly shared to us.
Assembly language made me appreciate computer architecture ,Pascal hits me to the extremities of graphical User interface as Super Mario then was so popular computer games-and to inform you it was developed in Pascal. But as oppurtune knocked the door for computer programmer s I'ved realized then that there were changes in maket demand of software programming ;VB6 and a VC++ for application programer and a C origin JAVA++ for a WEB programmer . VB6 dominate much on Database programming wich included killer apps : interface to ADO,MSQL,MSACCES and etc.VC++ and it continous revision with its excellent platforms such device drivers,libraries and addons beside C/C++ entices the majority of the use of computing research to almost University/Insitutions ( a middle level class of programming).
In my own analogy that is business and MicroSoft had supported these two programming languages and included to its package accesories-Visual Sutdio. It was not so surprising becuase MS Windows was built in C and so was its rival OS Linux.Though of such cases Pascal now caveat is Delphi and Assembly never joined the competitions except it play as a useful programming tool to hardware embedded programming. Sometimes Assembler is being used as an inline interface to its 3 contemporaries compiler or interpreter-BASIC,PASCAL and C/C++.
So , what I learn through it was that somehow this " Big 4" really influenced our digital world -nonetheles the syntax the logic and functions.
