Similar reflection, I ran `kitten __benchmark__ --render` in rune, the CPU time spent was 1:55. I ran the same in a libghostty based terminal emulator and spent 0:44 on CPU. I say this only because yes you can do engineering to meet the ben

The build time claim in the blog post is dubious, part of the problem is CGO isn't fast, but also if build time was really a motivator the null build path is entirely unoptimized for objects with long build times: cached null (no chang

SQLite has an online backup API as well, but it is slower and requires a significant additional page cache cost. The team chose SQLite early on (there are some blog posts about this) and then we vertically scaled against the SQLite architec

We have very good reasons for our checkpointing model, related to our backup + disaster recover strategy, along with resource cost. It might be worth writing about one day, so I'll not give away all the details, but in very short form,

So really the trend I'm talking about here is people turning SSH into a browser, hosting apps behind SSH that expect a much higher volume of TOFU happening, which is a departure from the "first time i setup my vps" kind of ca

When you see people advertising a coffee shop at a conference and people TOFU'ing on conference wifi then plugging in credit card numbers, the picture gets a little more clear.

sshfp is not PKI. It's an option and it is off by default in ssh(1). In practice no one actually deploys it, exe.dev, terminal.shop, jobs.{whoever.com}, etc. I've yet to see an in the wild deployment. The aforementioned sites let

The mental model of slow decay into copyable is complicated. The code base is already a wash with contributions that have low copyrightability in US case law anyway, things derived directly from external architecture or documentation in bar

Parse for what? The model has “arbitrary understanding” of “arbitrary input”. The filter is unbounded and the only actually safe result is to filter everything.

In my experience once you get to the point where you run out of space in the glob you’re often suffering with poor performance from spawning children as well and it’s time to move to a more formal program even if it’s a script, writing out
