eutectic··on Article reply “Godot is not the new Unity” from Juan Linietsky (BDFL of Godot)
We now have games which rely on shooting millions of rays per frame for rendering.
eutectic··on Texas power emergency heat wave
Presumably this means that power is underpriced (potentially for political reasons). Increase prices and any issues should fix themselves.
eutectic··on Why does the USA use 110V and UK use 230-240V? (2014)
Resistive losses are related to current (I^2 R), so you need thicker wires to deliver the same power at a lower voltage. I guess it was decided that it wasn't worth the expense.
eutectic··on Kullback–Leibler divergence
log 1/p is just -log p
eutectic··on Kullback–Leibler divergence
Negative log is the only decreasing function which satisfies f(x * y) = f(x) + f(y). If you have two independent events it makes sense that the total surprisal (information content) should be the sum of the surprisals of the two events.

Another way to see it is as a continuous generalization of the idea that you need n bits to represent 2^n equally likely alternatives.

eutectic··on GPT-4 can't reason
Language modelling is the objective (if we ignore RLHF). That doesn't mean that interesting kinds of reasoning can't emerge. You could just as easily dismiss humans as being 'biological replicators' which just 'reproduce their genomes'.
eutectic··on Llama2.c: Inference llama 2 in one file of pure C
I think for O(N^2) transformer inference you need to cache all the activations.
eutectic··on Our food tastes are turning salty and weird
Bacon and ham are highly processed and salted foods.
eutectic··on Every person on the planet should have their own website
I don't see the connection.
eutectic··on Why is desalination so difficult?
Yes, but there will always be some necessary energy input.
eutectic··on Why is desalination so difficult?
I think it's more a problem of entropy; You're taking a high-entropy mixture and trying to extract a pure substance. Think sorting red and blue lego.
eutectic··on The Bathyscaph Trieste: Technological and Operational Aspects (1962)
So is mine, and they made several successful trips which (among other things) makes me think that carbon fiber could be an appropriate material for a submarine. Metallic hulls would also implode catastrophically if not well designed.
eutectic··on The Bathyscaph Trieste: Technological and Operational Aspects (1962)
The Boeing 787 is primarily made from carbon fiber, including the wings which experience a mix of tensile and compressive loads thousands of times over their design lives. Of course deep sea submersibles occupy a much smaller market where a comparable degree of rigor may not be justified, but I think it's silly that everyone suddenly seems to be a expert in composite and/or submersible design.
eutectic··on The Bathyscaph Trieste: Technological and Operational Aspects (1962)
Well, obviously going with a more conventional construction would make it easier to come up with a safe design. But I feel like people are going to take the wrong lesson from this accident.
eutectic··on The Bathyscaph Trieste: Technological and Operational Aspects (1962)
When people say 'carbon fiber is weaker under compressive loads', or 'cylinders distribute compressive forces unevenly', these kinds of issues seem like engineering challenges not fatal flaws. I feel like the problem with the Titan submersible was the lack of respect for safety, not any specific design choice.
eutectic··on Show HN: PFAS.report – Measure the forever chemicals in your blood via Quest
Well, in the case of lead, I don't think it was irrational for individuals to feel disempowered. The solution was regulatory and societal change, but how many people want to devote their lives to being PFAS crusaders?
eutectic··on Show HN: PFAS.report – Measure the forever chemicals in your blood via Quest
PFAS are used in the manufacture of teflon pans, but teflon pans themselves are not a major source (as I understand it).
eutectic··on A 5.7 Terapixel Mosaic of the Surface of Mars
And presumably the atmospheric distortion is much less as well.
eutectic··on DfT Recommends Removing WiFi from Trains to Cut Costs
My experience in London has been quite positive.
eutectic··on Experiments in Making Cocktail Ice
I'm not sure it will be so easy to get the ice out if you let it freeze solid.
eutectic··on Significant breakthrough in search for Parkinson's biomarker
Seriously? You can't think of a more efficient use of the time and money?
eutectic··on A simple and eco-friendly way to make ammonia
The Haber process is already operating close to maximum possible efficiency, so there are no big gains to be had.
eutectic··on New nanoparticles can perform gene editing in the lungs
Why would small molecule drugs like these be so expensive? Limited market?
eutectic··on Tighter bounds on the expressivity of transformer encoders
I think it means the analysis accounts for rounding error.
eutectic··on Car alarms and smoke alarms: tradeoff between sensitivity and specificity (2012)
If you change the requirements for an insurance policy you attract a different risk pool. Just like health insurance companies offering gym membership to find healthier customers.
eutectic··on Reducing Iron Oxide with Ammonia: A Sustainable Path to Green Steel
What about electrolysis?
eutectic··on Solid-State Battery Has 2x the Energy–and No Anode
Any idea why utiliy-scale is so much more expensive than automotive?
eutectic··on When Will AI Take Your Job?
"never" is a long time.
eutectic··on Win-Draw-Loss evaluation (2020)
Presumably they are derived from self-play.
eutectic··on More than 75 percent decline over 27 years in total flying insect biomass (2017)
Bees live less than a year, so the number of dead bees can surely only be used as an indicator of changes on around that time-scale or shorter. Eventually fewer bees means fewer dead bees.
