How php compiles the source code ?

PHP compiles source code into Zend Engine bytecode - this is done by the Zend
compiler in zend_language_scanner.l, zend_language_parser.y and
zend_compile.c. This code is the executed by the opcode engine in
zend_execute.c and zend_vm_execute.h. The latter is generated from
zend_vm_def.h by means of the script zend_vm_gen.php.

For  a good intro to php internals there is a presentation in french

I saw it via this thread on php internals

RubyRails for PHP programmers starting points

If you have php code that needs to be converted to ruby/rails there are a few starting points
hyperpolyglot should be your homepage:

On the ruby site there is a nice intro on Similarities and Differences.

From Rails for Php Programmers i used this pdf PHP to Rails Reference (extract)
on the translating php cookies and session (params for post/get ...)

Also the PHP to Ruby reference is very good

Ps: main site seems to be down at the moment but i guess you can fork and build the reference yourself

Getting the list of friends and their feeds with python open_facebook

I use django facebook api and here is the example i use to list my friends and their feeds

new fdb firebird driver example :execute insert statement

Here is my example for inserting one row in firebird database with fdb python driver

Installing kinterbasdb on Ubuntu Server 12.04 64 bits (python 2.7.3)

 The official way is from svn , otherwise you will get this error

_kiservices.c: In function ‘_init_kiservices_ibase_header_constants’:
_kiservices.c:809:3: error: ‘isc_info_db_impl_isc_a’ undeclared (first use in this function)

Old driver and soon to be deprecated , the recommended way is to use fdb

svn co kinterbasdb
cd kinterbasdb

sudo python install

Connect to firebird using the new python fdb driver

Install the firebird driver (you might need firebird2.5-dev headers)

 pip install fdb

use this documentation link  for the moment

and here is your first connection

What oracle really wants is

A full rewrite of the Java classees with core api and classes and that is what Microsoft "suffered" with the C# Yes C#/.net combo is a bad rewrite of the Java language with COM api and all the unportable DirectX included
