I like learning new programming languages, but I'm always
afraid to try exotic ones in real projects, expecially
because most customers are already scared off enough when
they see Perl code :-)

=== General-purpose ===

 * '''C++''' - I know the ISO/IEC C++ 98 standard extensively, including
 most of the recent C++11 additions. I also know several C++ [[ProgrammingFrameworks]].

 * '''C''' - I regard C as a distinct language because the programming
 style and [[ProgrammingFrameworks]] differ considerably from C++.
 ISO C99 with GNU extensions is the probably the language I've used the most
 for low-level programming (see [[EmbeddedEngineerRole]] and [[OpenSourceDeveloperRole]]).

 * '''Assembly''' - I know assembly from several processors, but I
 can say I'm proficient only with the following:
   
  * Motorola/Freescale 680x0/Coldfire
  * Texas Instrument's DSPs (mostly TMS320C5xx)
  * The old Zilog Z80
 
 I've also used several [[MicroController]]'s, in the sense that I know
 the architecture and integrated peripherals.

 * '''Java''' - I wrote some Java code at Google, although I'm not a skilled
 Java programmer. Long ago I've helped create a large Tomact-based
 webapp for [[http://www.fieremostre.it/|Fiere Mostre]], mainly in deployment
 and production systems, with minor development work for user authentication,
 security and database access.  I've also done profiling, optimization and
 performance tuning work for a POS application based on IBM's JPOS.

=== Dynamic/Agile ===

 * '''Perl''' - I'm quite proficient in Perl, but use it mostly
 for one-liners and small utilities for my SystemAdministratorRole.
 These tools are a good example of my Perl coding skills:

  http://www.codewiz.org/projects/#newrpms

 I've also done deep Bugzilla customizations for a customer,
 which enables me to say that I've also used Perl in a real
 application too.

 * '''PHP''': I've teached PHP in a course done as part of
 my InstructorRole.  I've also wrote an
 online shop application in PHP back when PHP4 was not
 yet mainstream and you had to build it yourself.
 As part of my ManagementRole, I've also supervised two
 additional PHP projects developed at DevelerCompany. 

 * '''Python''': I know Python just a little.  See my
 PikiPlus changes for an example of my limited Python skills.

 * '''Javascript'''/'''ECMAscript''': Only superficial knowledge.

=== Scripting Languages ===

 * '''Bourne Shell''': I've been using bash as my main shell environment
 and wrote countless scripts to automate my work

=== Query languageas ===

 * '''SQL''': I've used it extensively and taught to students the
 basics.  The Database I know best is MySql, but I also have some
 experience with MicrosoftAccess, SqlServer, OracleDatabase, PostgreSql
 and others.

=== Not Properly Languages ====

 * '''regex''': Extended and Perl-compatible regular expressions.

 * '''HTML''': Extensive knowledge of the W3C standards (HTML 4.01 and XHTML 1.1).

 * '''CSS''': Some outdated experience with CSS1 and CSS2

 * '''LaTeX'''

 * '''make''': I can write really obfuscated Makefiles using the GNU Make extended syntax, autoconf, automake, etc.


=== Useless Languages ====

 * '''awk'''
 * '''sed'''
 * '''REXX'''
 * '''Turbo Pascal'''
 * '''Visual Basic'''
 * '''Brainfuck'''
