The last time I've used an interactive debugger was in the school, Visual Basic 6.0 used to have a nice one. That was 8 years ago, then I went to scripting and web development so debugging changed dramatically for me. So in PHP is different process, it was a bit tricky to get used to "print_r" debugging style instead of using breakpoints!

So, in the last few days, while struggling with lua-cgic (my first ever Lua extension yet to be completed), I found an I/O bug that forced me to remember: the use of breakpoints, C programming and learn GDB. All those three in a row!

GDB is an interactive debugger, basically you load a program, set breakpoints, run it and wait for the program to stop at some breakpoint. That is obvious for some people, and awesome for others like me :), just have to clarify that everything happens into a console, if you miss the graphic interface, try the GDB GUI called Insight.

Lua is an embeddable scripting language. If you are trying to embed it in PHP follow this instructions that may help you:

$ sudo apt-get install phpize liblua5.1-0-dev 
$ git clone git://repo.or.cz/phplua.git src
$ cd src/
$ phpize
$ ./configure

At this point you are almost done, BUT please edit the file Makefile and change the line:

LUA_SHARED_LIBADD = -llua

by:

LUA_SHARED_LIBADD = -llua5.1

Then is time to finish cooking:

$ make
$ sudo make install

Almost done, do a test:

<

pre>
$ make tests #all will fail, that is fine by now

Install basement

$ sudo apt-get install apache2-mpm-worker liblua5.1-0-dev
$ sudo apt-get install libfcgi-dev libapache2-mod-fcgid

Install Luarocks

Download latest version from: http://luarocks.org/releases/, extract it, open a terminal and do a "cd" into its directory, then:

$ ./configure --with-lua-include=/usr/include/lua5.1/
$ make
$ sudo make install

Install WSAPI

$ sudo luarocks install wsapi-fcgi

Configure Apache

If you are an screencaster, for sure you know that there are not much options to grab your desktop + microphone at the same time. Perhaps you have tried some java programs, or simply switched back to windows and used a virtual machine. Too complicated!

Hopefully, there is still an opportunity: recordmydesktop+jack. I will not describe how to install jack here, sorry, google is your friend :)
But once you have jack up & running, do the following:

Download sources
$ apt-get source recordmydesktop

Install development dependencies
$ sudo apt-get build-dep

Yes I'm still alive and working on SLPOR 2008, reason for
troubles editing the banner design donated by Proyect-One which was in AI.
I've tried several programs, including SK1 but got into troubles, here
howto install in debian sid:
$ sudo apt-get install tk8.5 tcl8.5 python-liblcms zenity python2.4
$ sed "s/python /python2.4/ " /usr/bin/sk1 > /tmp/sk1 && sudo mv /tmp/sk1 /usr/bin
$ rm -rf /tmp/sk1 && sudo chmod 755 /usr/bin/sk1

I'm consternated with my Debian sid, I can't capture my screen with xvidcap or istanbul anymore, marvil told me that they work in Ubuntu, why not in Debian?

It was a pain the ass to research for a good an usable solution for me, because I have an old laptop CPU(Centrino 1.8Ghz), but 2 weeks later, here is the best solution I found at the moment. Sox is a "Swiss army knife of sound processing" with sound recording capabilities and ffmpeg is a "multimedia player, server and encoder" with screen capture capabilities.

It is one of my first posts in english(recovered from: http://www.linuxforum.com/forums/index.php/topic,137025.0.html): I don't know if it is new, but today, alfer a large week of intensive research, finally i had discover a way to access visual foxpro databases directly from linux. What do you need? download, compile and install CLIP from http://sourceforge.net/projects/clip-itk/ then put the vfp table into the same directory of the next script:

file: testdbf.prg

use dbftable
list columnname

1. The lack of documentation,
2. The OOP style of programming,
3. The confusion between all the different elements and API involved
