In case people are wondering why GitHub has been having some issues as of late - the GitHub COO recently shared that they're handling up to an order of magnitude more traffic than they were a year ago.
It's not like GitHub is just serving up pictures and text - things like the core git backend and actions are quite complex to host at scale. Idk, I guess I'm not surprised there are some stability issues when they're going from handling 1 billion commits/year to 14 billion commits/year.

I just went in for my third dose against Tick-Based Encephalitis, and the lovely person administering the shot told me that they are expecting to be able to provide immunization against Lyme disease either in 2027 or 2028!
Apparently Pfizer has a vaccine currently being trialed in phase 3. And they expect it will go well, which means a vaccine might actually become available soon!

Oh the other hand: having plugin management built directly into nvim is awfully convenient.
I want to see if I can restore the base key bindings, and then maybe also remove the popup screen. Can't say I love how barebones base neovim is either lol.

2025-08-24 19:27:30 UTC

On the topic of Vim: I'm back behind my computer again today after having touched grass for a week. And yeah no, I don't think I actually like Lazyvim that much?
I feel like it messes with too many of the default settings; in particular overriding the `g-n` bindings to mean something else.
Lazyvim very much feels like a neovim-based editor, rather than a "configured neovim” instance. Kickstart vim seems much better for what I want imo!

Looking at the tags here, the current nightly is tagged v12.0: https://github.com/neovim/neovim/tags
I'm not familiar enough with neovim's release schedule to say anything particularly informed; but just looking at their historic release schedule it seems that neovim 12 might be somewhere between 2-6 weeks away?

2025-08-16 11:43:59 UTC

Oh wow, starting from version 11, Neovim will not only begin shipping with a native package manager (!), it will also begin shipping with native LSP support (!!!).

Nope, I give up. Helix just isn't there yet for me. It:
- doesn't have working reflow key bindings, which they inherited from Kakoune
- doesn't have support for tabs (a 400 LOC PR has been open for years)
- doesn't have a plugin system (and they're going to design a new language for it, it sounds like?)
- doesn't render diagnostics in a way that I enjoy reading
- doesn't have support for mini map/scroll bars
I think helix is a cool project. But I really can't see myself daily driving it as-is

Found out the other day that the IETF uses Zulip too. So does the Rust project. So does the Bytecode Alliance.
Do I have issues with Zulip? Yes, plenty. Does Zulip send me notifications to buy "orbs"? No, never. And I'm glad.

2025-08-14 23:34:15 UTC

Say what you will about Zulip; at least they're building a piece of software that works and seems to be gradually improving over time.
As a company they don't seem particularly interested in engaging in the hyper-growth-or-die cycle that so many other companies fall into. And like, for something I treat as infrastructure, I think that's great.

Zellij's support for stacked windows is so nice! I now have a setup where my main pane has my editor, but my right pane has a stack of three different programs I can rotate through:
- a regular terminal session
- a tui-based git client (lazygit)
- a tui-based file explorer (yuzi)
In the future I plan to configure this further by creating additional, project-specific panes too. For example: dedicated `cargo test`, `cargo check`, and `cargo run` panes.

I was wondering whether the receiver chipset was maybe too bulky to include in phones; but I don't actually think so?
Check out this LoRa cover for the PinePhone:
https://pine64.com/product/pinephone-pinephone-pro-pindio-lora-add-on-case/
If you disregard the size of the dedicated antenna, the actual chipset doesn't seem unmanageably big? For a 15KM-range P2P radio/network protocol? I can see that being worth it?
This is *fascinating* to me. I really wonder what the catch is with LoRa; surely there must be one?

My bad: not a 1.5KM range, but a 15KM range. I need to learn more about LoRa/LoRaWAN. But on paper: hooolyyyyy, why isn't this more widely used?

LoRa/LoRaWAN, at least on paper, should have a range of up to 1.5KM, with good battery life, and no subscriptions required. It's designed for lightweight trackers. I'm just really confused this hasn't yet been commercialized for pet trackers?

2025-08-10 15:14:08 UTC

I'm looking at the state of cat trackers, and I can't believe there aren't any commercially-available LoRa/LoRaWAN-based trackers available.
The first category of devices are airtag-like trackers (2.4gHz), which have good battery life, are light-weight, have no subscription required, but with only a range of around 15-30M.
The second category are GPS/Cellular-based trackers, which have an unlimited range, but are bulky, have bad battery life, and require (expensive!) subscriptions.

For me the most interesting part of this project is the plugin system itself tbh. I think what we've done for Wassette should not be that hard to reproduce for other systems and protocols that want to have an extension system.

Introducing Wassette - a Wasm runtime that exposes Wasm Components over the MCP protocol:
https://opensource.microsoft.com/blog/2025/08/06/introducing-wassette-webassembly-based-tools-for-ai-agents
The entire industry seems to be driving to create MCP-based tooling for their products. But what if, 1) those tools didn’t just have to be specific to MCP, and 2) we could actually employ good security practices like sandboxed execution of untrusted code, deny-by-default access to system resources, and so on. All stuff that imo you’d hope to see in a plugin system.

I’m thinking back to a previous gig where I was tasked evaluating the integration of a new database into our system.
I believe it required three separate containers to run the database. Of which at least one had what felt like, 200-300 different CLI options? Just pages upon pages of tunable parameters and configuration settings.
It felt that in order to effectively run the database you needed to understand the database internals. And we had nobody on our staff like that.

Of course these results need to be reproduced to be fully generalized to countries outside of Greece. The concrete numbers may of course vary from place to place.
But intuitively this also makes a lot of sense. Waterborne and foodborne diseases are strictly controlled for. Surface-based transmission is by nature a lot less transmittable. It makes sense that airborne diseases, which have virtually no controls, are the main remaining vector.

2025-03-29 15:12:05 UTC

You know how memory safety issues are responsible for approx 70% of CVEs and that’s considered a huge deal and worth mitigating?
What if I told you diseases had a very similar stat. Where about 85% of all sick days can be attributed to airborne diseases:

For people wondering about the different meanings of ‘static:
- In references it means that the data pointed to by the reference lives for the remaining lifetime of the program.
- In trait bounds it means the type does not contain any non-‘static references.

Rust guides are generally pretty good about telling you about the three ways by which values can be passed (owned, shared ref, mutable ref). But it's far more rare to hear about the three kinds of lifetimes Rust has (covariant, contravariant, invariant).
And then there are lifetimes like ‘static that also have their own rules that can be tricky to get your head around. 'static also has different meanings depending on whether it's used in trait bounds or in references.
Lifetimes are not easy!

Pointer Provenance and Lifetime Variance have a lot in common. Neither is directly encoded as part of a type; but the compiler very much cares about it, and needs you - as a programmer - to also care about it. Though it may not be forthright about wanting you to.

Survived release day. Very tired now. But also somewhat pleased about it.
It’s nice being able to actually show people what Wasm allows us to do. In this case: zap entire chunks of traditional compute stacks. It’s a lot of work; but we’re also just kind of proving that we can just do the work?

New new new on the Microsoft OSS blog: We’ve released a Wasm Component guest for the Hyperlight hypervisor!
We talk a little about what this means and how it works on the blog. But tldr: we’ve made it possible to start new VM partitions, load a Wasm runtime, and start executing a Wasm Component binary in about ~1ms. No guest OS. No virtual devices. And I think that’s pretty cool!

It’s so fun. I’ve cast “recast special interest” and it just worked. Somehow!

@nprofile…hmrr
Both threads and tasks are unjoined by default. For either, if you drop the handle the work continues by the handle is now unreachable. Meaning the output is no longer directly observable. And in the case of async: the operation can no longer be cancelled.
See https://blog.yoshuawuyts.com/tasks-are-the-wrong-abstraction/ for more

I’ve been reading more about control systems, and I’m now thinking: cancellation in async programming is a form of feedback control!
Structured concurrency is an attempt to create closed feedback loops where we can apply feedback control (add more work, cancel work) and always observe the output signal (return values, errors).
Unstructured concurrency (e.g. task::spawn) creates open-loop systems that can lose signal and cant always receive feedback. Which is inherently brittle and unstable.

(Somewhat keen to properly make my way through the control systems and concurrency books I’ve got in my library. Feel like I finally have the required context to re-read them more thoroughly.)

The only downside of this is that I meant to spend about half as much time on that today, and spend the rest of the day reading. Ah well.

Spent about 7hrs in the kitchen today making food for the week. There’s something oddly soothing about just making things that is hard to replicate any other way.

Oooooops, confused author names. Different John than what I wrote in my original toot.

In other news: I finished John de Goes’ book “a philosophy of software design” this week. Thought it was decent; I think he makes some solid points overall. Especially enjoyed the start where he tries to capture what complexity precisely is.
I suspect most practitioners with 10+ years in the field will know most of what the book says already, like intuitively. But not a bad read to have some of those things explicitly repeated back. Decent book overall imo!
