Last year I opened my Meta Ads dashboard, did the math, and just stared at the screen for a second. I had spent more on running ads that week than the store had made. Not close. Actually more. So yeah. That's where this series starts. A bit of...

certbot had been running quietly on my server for almost two years without a single issue. Automatic renewals. Silent cron job. I never thought about it. Set it up once, tested it once, and mentally moved it to the "solved" column of my infrastructu...

UUID v4 is the default choice for most developers. But UUID v7 exists for a reason — and if you're using UUIDs as database primary keys, the difference matters significantly. What's the difference? UUID v4 is 128 bits of cryptographically random da...
