this has helped (if i remember right) multiple people now, so, recommendation: if you take antihistamines, and they make you sleepy, and you don't want them to make you sleepy, consider 3rd gen ones like fexofenadine. day and night difference

We take it for granted today, but a single 6W embedded NPU can do more tensor operations per second than a peasant in the 1400s could perform in his whole lifetime

Publishing “Cryptographic Right Answers” for developers is a tradition by now. Colin Percival started in 2009, Thomas Ptacek followed up in 2015, and then Latacora carried on in 2018 and 2024. I put together a list updated for the renewed urgency of migrating to post-quantum algorithms.

I would like to formally announce that the #GlasgowInterfaceExplorer revD development (the next iteration: with the same FPGA but 32 digital I/Os and 8 single-ended analog channels that can be configured as 4 differential ones) is well underway with a CS campaign planned later this year; stay tuned!

believe it or not, in america, even the missiles are made of corn

Felix Colgrave@felixcolgrave.bsky.social

The USA does frightening alchemy to corn, makes it into battery acid or whatever, but at least they have corn. Australia is the USA with no corn. The British just rocked up and ignored every plant like "gee I hope we can make baked beans grow here or we're fucked"

added a new #GlasgowInterfaceExplorer applet, `control-clock`: a simple clock generator for when you just need to feed something into the XI pin of an MCU or something. you can use it in combination with other applets! e.g.: `glasgow multi probe-rs ... ++ control-clock --clk A7 -f 2000`

To study Twitter is to study archived Twitter. And if you're replaying archived pages, you need to be familiar with the different generations of UIs. Tarannum Zaki of @webscidl.bsky.social explores and classifies the different UIs. ws-dl.blogspot.com/2025/10/2025...

i feel somehow obligated to post a clip of most of the opening scene of Kabukimonogatari, where Ougi discusses the meaning of stop lights with Araragi, as a metaphor for how people aren't sufficiently cynical about the world

we do respect in theory the concept of trying to avoid sounding like a weeb when translating, but the problem with that is that the monogatari series is fundamentally otaku media, the characters constantly make otaku culture references, they *should* sound like weebs you know!

Being a transsexual puts you at an inherent advantage with FPGA engineering, since you already have experience with reconfigurable hardware alongside minimizing clocking issues.

Of course delightfully apt that when you have no clocking issues; the FPGA toolchain says your design passes (passes timing analysis, that is).

the next problem was to *modulate* the signal with morse code. he used another mag amp. this one *detunes* the giant transformer that gathers current from all the poles and matches the impedance to the antenna array. turning off the key shifts the frequency, reducing the output power by over 90%.

the next big problem that Alexanderson had to solve was controlling the speed. any variation caused the output frequency to drift out of the range that the antenna could support. this circuit uses a closed-loop design with a resonant filter to control magnetic amplifiers.

so now the maximum frequency is controlled mainly by the speed and the number of slots in the spinning rotor. and those can be packed together pretty tightly! it's very similar to how a Hammond organ works.

see, a alternator's output frequency depends on 2 things: how fast it turns and how many *poles* you have (basically groups of windings.) to bump up the frequency, you have to put on as many poles as you can physically fit and then run it as fast as you can!
