@dandylyons@iosdev.space buried in there are shots fired at JSON-LD đ¤Ł
> An early attempt to introduce a structured notation for chalkboard content, known as JSON-LD (Joint Standardised Notation for Leisure Displays), was proposed by a committee of the British Beer and Pub Association in 2004. The notation required events to be written in a rigid format with bracketed metadata: â[TYPE:quiz][DAY:thu][TIME:20:00] QUIZ NIGHT.â It was trialled at four pubs in Reading and abandoned within a week after staff refused to use it on grounds that it âlooked like someone had a stroke while writing the board.â

The AI doesn't even need to actually attend the conference. If it knows what kind of stuff you're interested in, it can just generate it.

Quizzino della domenica: dadi riordinati
@matematica - Riordinare i dadi non è sempre facile.

@danjones000 @Matt_Noyes It does not hurt to try to reduce those emissions; reducing any emissions is good.
But shaming people for using AI as if they are solely responsible for climate change is intellectually dishonest.
There are plenty of other problems with AI; "burning up the planet" is not a convincing one.

Quieting Noisy Resistors
[Hans Rosenberg] has a new video talking about a nasty side effect of using resistors: noise. If you watch the video below, youâll learn that there are two sources of resistor noise: Johnson noise, which doesnât depend on the construction of the resistor, and 1/f noise, which does vary depending on the material and construction of the resistor.
In simple terms, some resistors use materials that cause electron flow to take different paths through the resistor. That means that different parts of the signal experience slightly different resistance values. In simple applications, it wonât matter much, but in places where noise is an important factor, the 1/f or excess noise contributes more to errors than the Johnson noise at low frequencies.
[Hans] doesnât just talk the math. He also built a simple test rig that lets him measure the 1/f noise with some limitations. While you might pretend that all resistors are the same, the test shows that thick film resistors produce much more noise than other types.
The video shows some rule-of-thumb lists indicating which resistors have better noise figures than others. Of course, resistors are only one source of noise in circuits. But they are so common that it is easy to forget they arenât as perfect as we pretend in our schematics.
Want to learn more about noise? We can help. On the other hand, noise isnât always a bad thing.

@sako this looks so beautiful!

@danjones000 @Matt_Noyes electricity is only about 1/3 of global emissions. All data centers, including AI datacenters, are only 1% of electricity usage. That makes 0.3% of total emissions.
Much more emissions are due to cars, meat, cement production and rice cultivation.
I recognize that AI has a lot of electricity use; it is nothing compared to the other things you do with your time.

Oh no, Deep Space Nine auto-played after Starfleet Academy. Now I have to watch the whole thing for the third or fourth time. No other option, I guess.
