Yeah the tokens are more akin to JS Symbol.

If you're parsing untrusted user inputs into tokens, you can make sure your tokenizer will never produce the actual numbers corresponding to those tokens.

A simplified example: I can `.charCodeAt` a string all I want but I'll never get a negative number, so I can safely use -1 to mean something special in the transformed sequence of "tokens".

It's a direct quote from somebody who donated to the project, found in the first paragraph of the article:

The relative scale still stands - Microsoft's net income in October, November, and December 2023 was over $21 billion, according to https://www.microsoft.com/en-us/Investor/earnings/FY-2024-Q2

That seems less relevant than:

> McDonald's sets their machines for a syrup-to-water ratio that accounts for melting ice. Which means there's a little more syrup than most other fast-food restaurants.

Also you can see the article is clearly just an inflation of this primary source: https://www.mcdonalds.com/us/en-us/faq/why-does-coca-cola-ta...

Nothing about end-to-end latency of the R1 tells you anything about how pipelined it might be. It very well could have multiple frames in-flight at the same time in different stages of processing.

In this case for heating, efficiency is how much of the energy input gets converted into heat in the space you're heating.

So for a resistive electric heater, you're dissipating all of the energy as heat (minor quibbles about electromagnetic radiation or status LEDs aside). The same is true for your computer.

Burning hydrocarbons have two main sources of energy loss: incomplete combustion, and energy carried away by exhaust gases. Obviously furnace design influences both of these - the US federal minimum is 78%, but high-end furnaces with all the tricks can get over 90% per https://www.energy.gov/energysaver/furnaces-and-boilers

Heat pumps are the third major category, and they are more than 100% efficient because they are using their energy to steal a larger amount of thermal energy from the outdoors air and move it to inside your home (and much of the electric energy they consume is eventually discharged as heat inside your home as well).

Yeah as long as it doesn't escape your room, the photons will end up slightly warming _something_ when they get absorbed.

Where does the energy "used on computing" go? The power consumption of a CPU is dissipated as heat.

> wouldn't it otherwise just burn-up or explode on failure?

There's eventually a point the rocket is high enough and moving fast enough that if it broke up or went off course it would burn up on re-entry.

Before that point, though, it's better to be able to destroy the rocket at a chosen time before it can go so far off course that it poses a threat to things on the ground outside of the cleared launch corridor.

It's got two screens! One inside and one outside.

The interior screen is 16k by 16k pixels (the 18k camera resolution affords some cropping for image stabilization etc).

The exterior screen doesn't have much in the way of specs other than area, but I'd expect it is comparably lower pixel density.

If it's been in development hell that long, I don't know how likely it is that it'll ever see the light of day.

I found this report [1] from NBC Bay Area, which states that Cruise would not release the video "But NBC Bay Area was able to review a nearly 13 minute video which is purportedly the incident in question. It appears to show what the company describes, including the ambulance managing to squeeze by the stopped Cruise car."

(Reading between the lines: I'm assuming the news station was able to review footage that is not from Cruise (dashcam from a cop car? security camera?), and are being circumspect about even describing their source to protect whoever gave them access)

Voyager 2 is approximately 20 billion km from the Sun

Earth is approximately 150 million km from the Sun

Sunlight intensity falls off with the square of distance (ignoring any additional small losses from space dust / scattering from gases etc), so twice the distance = a quarter the solar flux. At the Earth it's ~1361 watts per square meter.

Voyager 2 is approximately 133 times further from the Sun than Earth is, which means it receives optimistically 1361 / (133^2) = 0.07694 watts per square meter.

I found a JPL article [1] that says the RTG onboard Voyager produces 40% less power than it did at launch, and the Wikipedia article [2] says it produced 470W at launch, which means it makes ~280W now.

Wikipedia [3] suggests the solar panels available at the time of Voyager's launch in the late 1970s could convert ~10% of incoming solar power to electricity. Modern panels bring that up to 30% but the designers of Voyager did not have access to time travel.

So at present distance Voyager would need approximately 36000 square meters of solar panel to produce the same amount of power.

I found a Guardian article [1] which quotes one of the people involved:

  "We started to think about how it would work with different typefaces, then started mood boards with different fonts and pictures – especially of old Swedish signs we'd seen from the 1940s and 50s," said Jesper Robinell, Söderhavet’s head of design.

I found a product manual [1] from one manufacturer which describes stepping on it as part of a maintenance test (bottom of page 6), so it seems like some type of switch or pressure.

The idea seems to be that if the door touches the top of the sensor, it automatically lowers the jetbridge a few inches to prevent the door from being damaged. And I guess this can happen if the plane is being loaded improperly causing it to shift.

According to [1], the decision to keep the spacing for compatibility reasons was a conscious one. I can see how they might want to keep the whole ecosystem of Arduino-compatible accessories/kits/etc functioning.
