irrelative··on FP8 is ~100 tflops faster when the kernel name has "cutlass" in it
Correct, this is the actual headline too. 100 tflops sure seems like it'd be more than that, but here we are.

If the headline was "FB8 is ~7% faster when kernel name has 'cutlass' in it...", it wouldn't seem sensational.

irrelative··on Jimmy Carter has died
Flying is incredibly less expensive largely due to deregulation, and Budweiser has always been brewed with rice. So, yes, this is winning.
irrelative··on Ask HN: Why is .NET never talked about as an option for solo/small team dev?
It is, and small teams were often rebelling against incumbents, so rejecting the aesthetics of big companies was a good way to attract talent.
irrelative··on Pipe Syntax in SQL
Seriously. It’s not like that was the actual purpose of html or anything.
irrelative··on The Era of 1-bit LLMs: ternary parameters for cost-effective computing
Hadn't thought about it this way before, but given that LLMs are auto regressive (use their own data for next data), they're sensitive to error drift in ways that are rather similar to analog computers.
irrelative··on We've already seen category 6 hurricanes – scientists want to make it official
Classic spinal tap. “These go to eleven.”
irrelative··on Finance worker pays out $25M after video call call with deepfake CFO
Only if it works >4% of the time.
irrelative··on Scale of methane leaks from fossil fuel production and landfills exposed
Well a carbon tax would essentially end coal.
irrelative··on Japan ANA Boeing 737-800 flight turns back due to cockpit window crack
Or perhaps you overestimate how many people hold any view of Boeing at all.
irrelative··on A battery has replaced Hawaii's last coal plant
While I'm sure some chemical byproducts come out of that, it's important to note that hydrocarbons assuredly make some really nasty stuff along the way [1]. I also wish there was a way to more easily compare these things, but the misinformation around environmental data is really next level. General, consider thinking about renewable infrastructure as more of a stock that accumulates vs fossil fuel usage which is a flow.

irrelative··on Cicadas are so loud, fiber optic cables can ‘hear’ them
(slightly) less pop science version: fiber optic cables are so sensitive, they can even detect the sounds of cidadas.
irrelative··on Trying to make sense of why Otis exploded en route to Acapulco
Watts aren’t energy, so no idea what this means.
irrelative··on SQLite 3.43
Anyone know why this chart[1] hasn't been updated in a while? One of my favorite displays of incremental improvements in a project.

irrelative··on Live Starlink Satellite and Coverage Map
Roughly 30 times faster than an airliner.
irrelative··on You could have invented futexes
Note that futexes aren’t especially new to Linux anyway. They first appear in kernel version 2.6 released in 2003.
irrelative··on EU was set to ban internal combustion engine cars, then Germany changed its mind
Or we could make a generalized solution, like a carbon tax, that will minimize the government picking winners.
irrelative··on These Stupid Trucks are Literally Killing Us
I agree it's not wrong to like trucks, and that hating on the owners is a cheap shot. I also think that this video points out the externalities that trucks impose. In a rational society, one would expect the government to address these externalities, but here we are.
irrelative··on The Inner Beauty of Basic Electronics
The low voltage side of a transformer needs to handle more current. You could use the same gauge on both sides and get the same voltage, but you'd experience more losses.
irrelative··on Health insurers just published close to a trillion hospital prices
Sure, could be simpler, but there's a spec and multiple implementations: https://www.rfc-editor.org/rfc/rfc4180.html And the spec is ~5 pages.

Not sure why NDJSON is considered simpler, as json objects can be arbitrarily nested. Breaking into records is easier, but parsing is harder.

irrelative··on Twitter data breach exposes contact details for 5.4M accounts; on sale for $30k
Hopefully “for sale”, not “on sale”
irrelative··on Toyota warns about rushing into electrification
Lithium-Iron-Phosphate chemistries appear likely to be the choice for less flashy vehicles, and don't require cobalt or nickel. It's slightly less energy dense, though has some other benefits.

Lithium mining can be increased, though perhaps not at current price points (unsure about this).

I'll agree that 2 EVs per suburb house is a bit absurd, but it was absurd before EVs too.

irrelative··on Revisiting the “Tsar Bomba” nuclear test
There was a sort of doomsday device built by the Soviets:

https://www.npr.org/templates/story/story.php?storyId=113242...

> If there's a crisis, somebody in the Defense Ministries has to turn it on, so that's the first step. It then tries to find evidence that there's been a nuclear hit on the Soviet Union. If it determines that there has been a hit, then it tries to communicate back to the Defense Ministries. And if it can talk to them, it says, okay, humans are still alive. I don't need to work. I'll shut off.

> But if it can't communicate with them, then it knows there's been a crisis. We've been hit by a nuclear warhead and all the lines of communications with the Defense Ministries have been taken out. So now, we need to bypass all the traditional layers of command authority, and suddenly, the ability to launch a nuclear retaliatory strike is given to some junior official in a bunker.

irrelative··on Reverse Wealth Transfer on Steroids
Not to nit apart the title, but it seemed a bit strange to me. "Reverse wealth transfer" seems to imply wealth transfer has directionality.
irrelative··on “Location-Based Pay” – Who are we to complain?
I don't think that's true. See, for example,https://www.brookings.edu/blog/the-avenue/2019/11/22/for-the...

Not just the computer.
