It was 3 PM on a Friday. A doctor at an NHS hospital in the UK tries to check his email. Instead, one of the PCs in the room reboots into a scary red screen demanding $300 in Bitcoin [23].
In May of 2013, Yahoo announced plans to buy Tumblr for 1.1 billion dollars. Yahoo’s CEO, Marissa Mayer, stood in front of the press and said, “We promise not to screw it up”.
Many devs adopt the git add . (yolo, just yeet it all into the commit) workflow. It is fast, simple, and usually correct. But eventually you’ll have files in your repo directory that should never be committed: secrets, generated artifacts, dependency folders, and random local junk. That’s what .gitignore is for.
Functions allow you to reuse and organize code. Instead of copying and pasting the same logic everywhere, you define it once and call it whenever you need it. They’re the most important tool for writing DRY code.

Say hello to apps.chofter.com, the new home for everything I build. The speed at which I ship new things has massively increased with the advent of AI, and I’ve been encouraged by the fact that, as I approach my sixth decade, new ideas for useful & fun things to build still come at me apace. These no longer fit on my personal homepage, which is a combination of work experience, interests, things I made long ago that are no longer relevant (but still interesting), and of course, the many apps & tools I have out there in the wild right now. The site was 100% built using Claude Code, which did an amazing job of inspecting all the various websites, app stores and code bases and constructing a site in 30 minutes or so. I had to push it to make the site more SEO friendly, pre-rendered to HTML rather than over relying on client side rendering, but that was it. So there we go, enjoy the delightful and hopefully useful apps that I’ve already built and will continue to build in the future
