@skua @markhurst Show me graphs of Maine's classroom teacher to student ratios for the last fifteen years. Show me teacher pay and average educational achievement. Show me child poverty rates. Show me data on kids needing food assistance and whether they are getting it. Show me vaccination rates.
@skua @markhurst There are lots of confounding variables other than laptops and tablets, yet we always see articles like this and almost never on the other factors. Yeah, a lot of this predates Covid, but there is a general lack of willingness to even consider or acknowledge the effects of this disease on children and the culpability that schools, school boards and society at large have in not making every effort to reduce exposure in an environment they are forced into.

Now THAT's a headline.
"The U.S. spent $30 billion to ditch textbooks for laptops and tablets: The result is the first generation less cognitively capable than their parents"
@markhurst imagine being the kid picked for this picture

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, you’ll learn that there are two sources of resistor noise: Johnson noise, which doesn’t 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 won’t 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] doesn’t 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 aren’t as perfect as we pretend in our schematics.
Want to learn more about noise? We can help. On the other hand, noise isn’t 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.
