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 TR1 additions. I also know several C++ ProgrammingFrameworks. * '''C''' - I consider C a different language from C++ because you end up using a different programming style and ProgrammingFrameworks. ISO C89 (and later C99) is the probably the language I've been using most often, mostly because I did lots of low-level programming in my EmbeddedEngineerRole and because C is still the prominent language in open source projects (see 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've been involved in a large Java web application (visible here: http://www.fieremostre.it/ ), but mainly as a Tomcat administrator and maintainer of the build and deployment system. The only development work I did is in 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. I know the Java language and much of JFC, but I'm not really into Java any more. Others you don't know or care about: Pascal, Visual''''''Basic. === 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/#loginfo 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 used bash as my main shell for a very long time and I've used it extensively for automation (see SystemAdministratorRole) and as part of using make and autoconf. === 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''': Incomplete knowledge of the W3C standard (CSS1 & CSS2). * '''LaTeX''': Only superficial knowledge (I cannot create macros, etc.) * '''make''': I can do wizardry with GNU Make macros, etc. === Useless Languages ==== * '''awk''' * '''sed''' * '''REXX'''
