Various distributions have meddled with ffast-math over the years. At one stage early on, I think Clear Linux might have used it, which was part of the reason they kept demolishing distributions on benchmarks. I don't know any that s

I was talking about this with the my kids (10, 7) the other day. Blew their minds a little that pretty much every power source comes back to the same central thing: moving magnets. Then I pointed out that our electric car does it in both d

As they call out in the article, accurately counting words is a bit more complicated that splitting by space. You need to account for all sorts of punctuation etc. When I've been asked this in programming interviews, I've almost

ripgrep absolutely tears through some large monoorepos we have at work, far faster than GNU grep. I imagine the performance difference is even more startling for anyone on a Mac who hasn't replaced BSD grep with GNU grep (install the g

Latency is absolutely killer with tapes, but bandwidth is still a major issue. The current generation LTO-9 is only capable of 400MB/s in throughput. That's still slower than a SATA3 drive. Last time I used tape in earnest was a

How would email being compromised leak a debit card number? Can't think of any service I've used online in the last decade+ that would send me the full debit card number that way, or even make it visible when I sign in to their w

They're not even that. AWS (via Graviton) and OCI (via the same Ampere Altra chips Hetzner are using) at least have had Arm servers in Europe for a while. AWS longer than OCI.

OCI released A1 Arm based bare metal (BM) and virtual machine instances last year too in EU regions, also based on the Ampere Altra chips that Hetzner is using. So Hetzner seems to be way off track with this claim about being the first dedi

That's not the core dev team, at all. Servo was a research group, building an experimental browser engine, parts of which did end up transitioning across to Gecko.

There's reasons why it takes time. The perspective that it's "just produce rebranded RPMs" really undersells even something as significant as the amount of server power required to recompile all the packages. You could

Something else important to mention is that dynamodb now re-consolidates tables. This is a lousy explanation, but Read/Write quota is split evenly over all partitions. Each partition is created based on the hash-key used, and there&#x2

I didn't hate Unity, but it had a bug (for me, and clearly a bunch of others based on the launchpad bug traffic for the bug I filed) that persisted for the entire time Canonical owned it, that meant I couldn't use it. I could repe

It relies on xdotool, which I don't think works on Mac? If I was still on mac, I'd probably try and use hammerspoon somehow. I used that for a few bits of automation, and I know it had ways to choose applications.
