Hello my friend, good to see you again. You are right on time (according to my ~4 years of monitoring data). #protistsonsky #radiolaria

I donโ€™t have a strong intuition about amperage, but that seems outlandishly high since 1 A can easily kill someone

The resistance of the battery itself is likely keeping the current well below this value

Because otherwise youโ€™d have like 6700 watts (power = amps * voltage) from a AAA battery ๐Ÿค”

Iโ€™m curious how high the amps really go in practice

To get resistance:

R=ฯL/A

The foil has a tiny cross-sectional area (A), maybe 4mm^2, about 5cm long (L), resistivity (ฯ) of 2.5e-8 => 2e-4 Ohms

Battery I measured at 1.35V => gives us about 5000 A

I was trying to fix the contacts in my #electric toothbrush and stuck in some aluminum foil. I came back a few minutes later and it was super hot- I had connected the #battery terminals together by accident ๐Ÿ˜…

I know from Ohms law V=IR so if resistance (R) goes to zero #current (I) goes to infinityโ€ฆ

I get that- so far o3 and the โ€œsuper high end modelsโ€ often needlessly over complicate things and spew jargon, which can make it seem like itโ€™s a smarter model if youโ€™re not paying close attending. 4o does this the least in my experience

OpenAI's valuation was based largely on Sam Altman's promises: that in a few years, GPT would be "artificial general intelligence" and then "super intelligence" โ€” starting with GPT-5.

Now we're told GPT-5 is groundbreaking because it fakes unit tests 50% of the time instead of 70% of the time.

We just need to write Booker off. He's a theatre actor at this point. He should work on Broadway.

Gillibrand is a piece of _____ too!

I was just on a website (that I like, for the record) thatโ€™s encoding an entire JPEG in base-64, *inside* an SVG.

The line is 1.7 million characters long and the โ€œSVGโ€ is 1.3MB which I didnโ€™t even know was possible for SVGโ€ฆ

I feel like this cannot be on purpose can it?

So, now we have unequivocal proof that Team TACO is working with and helping Cuomo in the NYC mayoral race.

ANY Democrat who sticks with Cuomo is collaborating with that asshole, and will be treated as such.

I am LOOKING AT YOU Cory Booker.

CSS Clicker a pure-CSS idle game where you build your own website

it's finally time...

this is css clicker, a fully-featured incremental game where your goal is to design your own personal website and get as many views on it as possible

the fun part? it's a pure-css game, meaning it runs no javascript or server-side code.

have fun!

Looking at the map of air quality around New York using US limits (left) and Spainโ€™s limits (right) tells you quite a bit about how the US views air pollution- and about how we make subjective judgements that shape our view of objective data

Yesterday I got hacked and robbed. This morning, I received this message on my phone: "Your $2,500 can be returned โ€” but only if you stop reporting on Palestine. There are plenty of other things you could focus on. Keep digging into this, and it wonโ€™t just be your money at risk."

La corta vida de trece rosas | Reportaje Fue uno de los episodios mรกs crueles de la represiรณn franquista. El 5 de agosto de 1939, trece mujeres, la mitad menores, fueron ejecutadas ante las tapias del cementerio del Este. Su historia sigue viva hoy en forma de libros, teatro, documentales y cine.

Every single person I know has spent tens if not hundreds of hours dealing with prior auths, changing insurance, trying to understand benefits, billing departments, fighting denials, etc etc etc.

Imagine that times every adult in the US. Itโ€™s literally that utopia meme

The idea of physical labor is astounding and mysterious to him since he has never done a minute of it.

I think something thatโ€™s often missed in the discussion of American โ€œhealthcareโ€ is the cost of peopleโ€™s time. Itโ€™s easy to quantify the exorbitant costs we pay, but the loss of time to battling through hurdles in the insurance company bureaucracy is enormous. In single-payer that just goes awayโ€ฆ

(2) Despite the lack of equivlence between groups, the very similar (bizarrely so, from my teaching experiecne) successive average course scores were used to argue for a positive experimental outcome.

I feel like Iโ€™m losing my mind reading this- did they not analyze the assessment levels (i.e. change in โ€œfineโ€ or โ€œdisqualifiedโ€ students) from figure 4a? Just intuitively that seems like a much more robust result than average score anyway

This is pretty astonishing. Usually when trying to make a claim with a negative result, the authors will at the very least temper their language and say the results are โ€œsuggestiveโ€ of some trend. Itโ€™s debatable whether that may be worthwhile, but this seems outright bizarre.
