If you're anything like me, your browser tabs have probably gotten out of control at some point. 20 tabs. 30 tabs. 50+ tabs. At some point, finding the one tab you actually need becomes a problem. That's why I started…
Every time I've needed signatures inside a product I was building, the same thing happened. The signature part took an afternoon. The contract part took weeks — because the legal text lived in someone else's WYSIWYG…

Most developers hate SEO because it feels like voodoo. We are told to "optimize for keywords" or "build backlinks," which sounds like marketing fluff. But there is a side of SEO that is purely engineering. Technical SEO…
A Content-Security-Policy looks like a firewall rule and mostly behaves like one. The gap between "I wrote a policy" and "I have a policy" is almost always one clause in the spec — and I found out I had misread one of…
