The “No Code” Delusion

Dynamic type systems are not inherently more open
Internet debates about typing disciplines continue to be plagued by a pervasive myth that dynamic type systems are inherently better at modeling “open world” domains.

The database I wish I had
I watched the talk " Platform as a Reflection of Values: Joyent, Node.js and beyond " by Bryan Cantrill, and I think he was able to put into words something I already felt for some time: if there’s no piece of software out there that reflects your values, it’s time for you to build that softwarefootnote:talk-time[ At…

Apple M1 vs. Ryzen 3900X vs. Intel I9 in Software Development
I'm pretty impressed by what I've seen with Apple's M1 Chip. It's really fast and powerful for essential everyday tasks, which include browsing the web, working with Intel-based apps, and using programming apps. Yes – the ecosystem is moving, and that may take time, but I think M1 is worth paying
