Today I finally finished the GO track with the dreaded Zebra Puzzle exercise. I started on May 1, 2026 and finished on September 2, 2026. Just over four months. I feel accomplished but not really fluent. I have 33 left on the PHP track. Now I can go back to the How to Build and Interpreter in GO and How to Build a Compiler in GO books I put on the back burner until this was done.
