T-shirts.

T-shirts about the reality of troubleshooting code when everything should work but doesn't. For developers who've spent hours tracking down bugs that turned out to be typos. Designs about print statements, stack traces, and the detective work of figuring out why production is on fire. From reproduction steps that make no sense to fixes that work for reasons you don't understand. Made for programmers who know debugging is reading more than writing, and sometimes it's just rebooting until the problem goes away.
