I work -or have worked- with:

• Go/Golang (weapon of choice ATM)
• NoSQL: Couchbase, Cassandra
• SQL: MySQL, PostgreSQL
• PHP
• C (ANSI C99)
• Perl & Bash
• current OS's: Linux (Slackware, Fedora)

I don't like:

• Java
• Solutions that are needlessly complex
• COBOL
• Answers with Regular expressions to solve a problem that didn't require Regex's
• Java

Stuff I find to be true:

• Java is the new COBOL
• If your solution relies on more than 3 regular expressions at any given time, you're part of the problem.
