Very nice, I always enjoy some low-level discussion like this. I found a small typo/editing glitch on the "RISC-V 101 page" [1]: - It's a trending CPU ("Instruction Set Architecture") recent years. It should

In Sweden, where the main glass recycler claims we're world-leading glass recyclers, the claim is that recycling saves 20% of the energy. That is not nothing ...

It's called Falu red [1], btw. Made from mining residual products and originally liked because it resembled luxurious brick. [1]: https://en.m.wikipedia.org/wiki/Falu_red

Well, kinda, there are still fees for things like the right to use the various USB logos and of course to allocate a vendor ID [1] ($3,500 for two years, and $6,000 respectively). [1]: https://www.usb.org/getting-vendor-id

I would expect that to break the "visible from any angle" feature, as you would see the image in reverse from the other side of the circle?

LEDs are surface-mount [1] and handled by pick-and-place machines [2], so I don't think they are particularly time-consuming to assemble. [1]: https://en.wikipedia.org/wiki/Surface-mount_technology [2]: https:&#x

This looks really nice and the prose had a positive/easy-going feel to it. When the actual code examples begin, the very first couple of lines confused me: package hellope import "core:fmt" Is the quoting of pac

As someone with both feet in the embedded development world, reading this from 1995 is fun: Note that even the RS232 port itself is a standard. And an inferior one; sending stuff at 9600 baud over a 7 wire connection is a travesty by mode

I had never heard of this, and the repo doesn't provide a lot of background ... it seems to be a handheld (!) pen with interactive point-for-audio features, for 2+ year-olds. Here [1] is the Ravensburger product page in German and here

Really? Wow. I had no idea, and I really tried to sound non-condescending. I simply don't agree that redundant casts are something to be ignored, since they can be harmful and hide actual errors (the cast is a bit like `sudo make me

Aha, so it doesn't know about void* being compatible with all (object) pointers, but so far just requires the pointers to match exactly? I see. Not sure why I was down-voted, I think that is ... not nice. :(

Very cool, congratulations! I took a 2-second peek at the code, and just wanted to offer a small piece of advice that I think makes it better. Or two, really. Counting is hard. Instead of (this is from parser.c): apply_result *ret = (

Ah, the "My Workstation" guy. I wonder if that text could be factored out and linked to in a sidebar or something (it's in every article I've seen from him, here).

It was in C#, not C. In C they are not standardized but there are requirements on relative sizes. Since C99 we also have `int32_t` and friends that expose sizes.

Norway for sure, they have been in NATO since they helped found it in 1949. Us Swedes needed a while to think about it, and joined on March 7, 2024. Sweden does not have the F-35, since we build our own [1] multi-role military aircraft. [1]

The Pico is a microcontroller, typically programmed directly "to the metal" using either your own code or RPi's SDKs. It is very different from the regular Pi boards, which are single-board computers that run a full Linux usi

In Swedish that is almost exactly what they are called, bat translates to "fladdermus" which is "fladder" (flutter) and "mus" (mouse).

Meta: I think the title would be better here if it came out and said query optimizers. That gives a less subtle clue that it's about databases than looking at the domain.

Perhaps it's rare with full programs written in assembly, but for performance analysis and optimization I think knowledge about these kinds of tricks (but probably updated for the N generations since 2004, of course) still have relevan

I think the article confuses "spinlock" with "busy-wait", which made me confused too.

Sure, but that is true at the "macro" scale too of (for instance) discrete RGB LEDs, or any other case were color is simulated by emitting red green and blue light. There is nothing unique in the regard with the sub-pixels except

Very neat, congratulations! Is it recording 25,000 hours of actual audio which it analyzes, or is it recording midi data?

Very cool! It would be fun with some kind of performance comparison against the "traditional" textured method. As usual with modern gpu stuff for (semi-, not knocking the OP) simple stuff like this I guess the answer to "how

Non-native English speakers might also be a contributor to this, for instance in Swedish the words are the same so "assembler" can refer to either the language or the tool. As usual in natural language it's pretty clear from

Uh, is it really clear to say that rockets "push against" something? That makes it sound as if they could absolutely not work in space, which they obviously do. "They push against their own exhaust" seems to be the idea
