I’ve had a love of programming since my first real summer internship back in 1999. Over the years I’ve programmed in Visual BASIC, PHP, Ruby, Perl, C#, SKILL, Ocean, Verilog-A, C++, Go, BASH, AWK, VHDL, SPICE, MATLAB, ASP, Java, C, SystemC, Verilog, and probably a few I’ve forgotten. These days, it’s usually Python, C and C++.
