mkj··on Map Clustering Is Not My Favorite
I think that's incorrect. Brains/eyes are good at looking for patterns.
mkj··on Map Clustering Is Not My Favorite
If you have less than hundreds of thousands of points, you can probably get away with drawing individual dots on the map. Computer screens are high res.
mkj··on Map Clustering Is Not My Favorite
There are excellent examples of the problem in Edward Tufte's "Envisioning Information". Have a look at http://blah.ksteinfe.com/181106/tufte_envisioning_informatio... for a few snippets of it, then buy the book.
mkj··on SpaceX to buy Cursor for $60B
I'm wondering who's going to buy pi!

(Edit sorry forgetting names, I mean who's going to buy Earendil). Good luck to Armin, he's done some good stuff.

mkj··on A Matter Wi-Fi Light Bulb in Rust on the Raspberry Pi Pico 2 W
It looks like github is just buggy in this case.
mkj··on Tracing a powerful GNSS interference source over Europe
From what distance? I would have thought $1M wouldn't go far
mkj··on Nearly half (44%) of every T-shirt goes to waste before you even buy it
Wait until they hear how much source code is thrown away to make software! I guess that's a bit ephemeral, but still probably similar in a lot of industries.

Clothes are weird shaped, weaves are rectilinear, it's a pretty tricky problem to solve. Unless someone manages to invent a non-rectilinear robot loom or something?

mkj··on Netherlands blocks US takeover of vital digital supplier
Solvinity is a pretty terrible company name.
mkj··on Flipper One Tech Specs
"needs clarification" looks like a pretty normal hardware design process as the details are finalised.

mkj··on The limits of Rust, or why you should probably not follow Amazon and Cloudflare
The rustcrypto crates seem a lot better maintained and will probably supplant ring in future. Ring maintenance seems hostile to use outside of expected use cases.
mkj··on How Cloudflare responded to the “Copy Fail” Linux vulnerability
If they're already running a custom Linux kernel build, why did they have AF_ALG enabled? Seems the perfect situation to limit features to only those actually being used.
mkj··on Fedora is now the default Linux recommendation, and Ubuntu did this to itself
They're talking about billions of dollars of market share, so how does debian get a mention being free? I'm suspicious of their methodology.

At least the infographics down the bottom are obviously full of slop

mkj··on What async promised and what it delivered
> Tokio’s dominance is function coloring at ecosystem scale

That isn't function colouring, but rather plain incompatible APIs/runtime. You could have the equivalent with non-async ecosystems.

mkj··on I am building a cloud
How is docker a context switch overhead? It's the same processes running on the same kernel.
mkj··on Quantum Computers Are Not a Threat to 128-Bit Symmetric Keys
What does ed448 mitigate against vs ed25519?
mkj··on The exponential curve behind open source backlogs
Fair enough. A 15 commit PR is still pretty long winded.
mkj··on The exponential curve behind open source backlogs
Looking at the PR discussed, it's 34 commits! I'd probably ignore that too as a maintainer. The PR description isn't particularly motivating, "Cleans up the implementation", "see #6735 for the actual motivation".
mkj··on Open Source Security at Astral
Isn't Nix just reinventing what Vesta did for software reproducibility decades earlier? https://vesta.sourceforge.net/
mkj··on The future of version control
Are you saying Bram hasn't worked on VCS problems much? https://web.archive.org/web/20071213090008/http://codeville.... is 20 years.
mkj··on Show HN: Sub-millisecond VM sandboxes using CoW memory forking
It looks like firecracker already supports ACPI vmgenid, which will trigger Linux random to reseed? https://github.com/firecracker-microvm/firecracker/blob/main...

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/lin...

So that just (!) leaves userspace PRNGs.

mkj··on John Carmack about open source and anti-AI activists
BSD0 doesnt
mkj··on RISC-V Is Sloooow
Does that page even say which RISC-V CPUs are being used that are slow? I couldn't see it, which seems a bit of pointless complaining.
mkj··on Show HN: Xmloxide – an agent-made Rust replacement for libxml2
Intriguing work! Does it panic on any bad inputs? That's better than memory unsafety of libxml2, but still a DoS concern for some servers.
mkj··on EU mandates replaceable batteries by 2027 (2023)
No it's not, it's 6pm!
mkj··on Rust’s Standard Library on the GPU
> For example, std::time::Instant is implemented on the GPU using a device timer

The code is running on the gpu there. It looks like remote calls are only for "IO", the compiled stdlib is generally running on gpu. (Going just from the post, haven't looked at any details)

mkj··on Why does SSH send 100 packets per keystroke?
It looks like it is only applied for PTY sessions, which most computer-computer connections wouldn't be using.

mkj··on My Home Fibre Network Disintegrated
Fs.com are a well regarded company. The OP should contact them and see if there's a recall on those cables or something. Sounds similar to what happened with some mains power cables sold by a hardware store in Australia.
mkj··on QNX Self-Hosted Developer Desktop
People in the industry would know that QNX has been around since the 90s (or 80s?) as a very solid embedded GUI platform. They're a company that doesn't need to prove their credentials.

I'd agree using qnx.software rather than qnx.com is kinda dumb though.

mkj··on Decreasing Certificate Lifetimes to 45 Days
That seems worth suggesting to the acme working group mailing list, if it hasn't already been discussed there.
mkj··on The fate of "small" open source
You'd get those benefits from traditional dependencies if you copy them in and never update. Is an AI dependency going to have the equivalent of "upstream fixes"?
