Linux Mint Vanessa, running the Mate DE.

The program is a C program with a single Makefile. My workflow was (and still is, even on my desktop) using a Vim with three vertical splits:

1. A LHS split which is a terminal to run make and execute the program for testing

2. A RHS split with the program source code (single file program).

3. A middle split with the test input file and test output file (in horizontal splits).

Although it is just a single file, on my other C projects I've used the same laptop, with the same 3-vert-split Vim, with multiple tabs, so up to maybe 16-20 source files open at a time for a single project.

Building C projects is very fast, even on the Core 2 Duo/2GB RAM setup. Running a similar workflow but in VSCode on my desktop is less snappier than Vim on the laptop.

I haven't tried doing a Go project on that laptop yet with VSCode, but I am tempted to see what happens :-)
