Debugging Is Like Being the Detective in a Crime Movie

Debugging is like being the detective in a crime movie where you are also the murderer is a line often attributed to the developer Filipe Fortes, from a 2013 tweet, and programmers have passed it around ever since. The crime scene is your codebase, the victim is production, and the evidence is a stack trace. The murderer turns out to be you, writing code at 11 PM last Thursday while making a small change.

The bug report says it's broken, the reproduction steps say click the button, sometimes, and the commit history says misc fixes. This shirt is for developers who've spent two hours bisecting through git commits only to find the culprit was a perfectly reasonable assumption that turned out to be wrong in exactly one case. You wrote the crime, you solve the crime, and the system works as designed.

More cases where the investigator and the suspect share a git username in the Bugs & Features collection.

The blank behind every t-shirt

Battle-tested comfort for uptime and off-days.

Most brands treat the blank as an afterthought. We treat it like the product it is. Every design ships on the same tee we picked after ditching the ones that pill, shrink, and go see-through by the third wash. Proper ring-spun cotton, soft enough to wear five days running, tough enough that the print still looks new long after your last deploy. True to size, no surprises. The kind of shirt you forget you are wearing, which is exactly the point.

True to size Pre-shrunk fit Unisex

Love it - but it was so long! Thankfully being a dab hand with a sewing machine I’ve managed to take it up to a reasonable length for the female form!
