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 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 used to be quite proficient in Perl, but today I use it mostly for one-liners. These tools are a good example of my rusty Perl coding skills:

  • Deluxe Loginfo
  • Newrpms
  • Extensive customizations to Bugzilla for internal use

• PHP: I've taught PHP in a web programming course as part of my TeacherRole. I've also written an online shop application in PHP back when PHP4 was not yet mainstream and you had to build it from source. As part of my ManagerRole, I've also coordinated two additional PHP projects at DevelerCompany.

• Python: I use Python occasionally for scripting and small webapps. See GeekiGeeki for an example of my limited Python programming 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
