What Hacker News says?
This is in the same vein as the "checkbox hack". It's a great rabbit hole to go down. It's fun to try and figure out how to accomplish normal UI functions with no JS and no page reloads. My personal favorite was making a popup Confirm/Cancel dialog where you could still see your content behind it. Cancel made it disappear; Confirm triggered a CSS url() call for the action. Here's a todo app with no javascript (not m…

HN discussionI recently started running more Google Cloud VMs in the UK instead of the US. It was costing me £2 a day to run the VMs, but somehow I also paid £12 a day for "GCP Storage egress between NA and EU”. Turns out that by default Google's Docker container registry only stores the Docker images in the US. So each time I launched a VM the Docker image was downloaded from the US. I wrote more about it here: https://www.matt…

HN discussionI've found a nice middleground to be writing a custom static site generator for each site. They can be quite small (here's one[0] in ~50 lines). Usually it just loops through a directory and turns Markdown files into HTML (with header injected), and syntax highlighting. Also, if you're really committed, you might be surprised how app-like you can make HTML+CSS, using things like checkbox and :target hacks[1]. The UI…

HN discussionI had a somewhat similar discovery with V8 (JS VM): V8 allocates a whopping 64 bytes per empty object. {} But if you initialize it with a single property, the size shrinks to 40 bytes. [1] {v8Hack: null} I too was creating lots of object that would stay empty, but V8 (incorrectly) assumed I was going to change them later so it reserved some extra space. [2] Unfortunately, there is no size hint like for Java's HashMa…

Never would have thought that Babel could be used for instrumentation, though after a bit of digging it looks like https://istanbul.js.org/ uses a similar trick! Is there a way to integrate this into a local dev environment without needing to run the MITM proxy? (For instance, if you know you're lo…

HN discussionMy approach is similar. I keep plain text notes on my phone where each line is something like "16 haircut" or "12o" (eating out). I have a Node script that I currently run manually, but the problem is that I only run it every couple of months... Using a bot keep track of things is a great idea! Currently I group everything by month, but using a bot would also allow that to be more granular. One thing I try to focus…
