I don't have the self-driving feature in my Tesla; I have, however, developed a significant respect for the torque it delivers. It is, by a long margin, the quickest accelerating vehicle I have ever owned. The first three weeks I own

Oof; yeah. So, Texas has a primary and then election system: candidates are selected for the ballot in the primary, and then voted on in the general election. The probability that a candidate will win the general election having won the pri

Texas tried to do this in the early 2000s; we even built a bunch of desalination plants (here's a comment about this I made recently): https://news.ycombinator.com/item?id=38422172#38424191 Long-story–short (bas

Dennard scaling stopped years ago. There's definitely room at the bottom for different topologies — probably 5–10 generations worth. But! These are probably 5 year steps, not two year steps. Also, there's just as much room for the

If they can bill me, they can tell me how much it'll cost. They know my address.

This article is junk. What is it saying? It's got the worst sort of clickbait headline, followed by the one line summary: recycling has a lot of complexity. The end.

This used to be a nightmare, for me. My dad still has this nightmare; he's 81. So... that's probably not trauma, right?

My suspicion is that we heavily subsidize road-freight traffic by not properly taxing very heavy vehicles: https://en.wikipedia.org/wiki/Fourth_power_law Reasonably loaded freight trucks do about 10000x as much damage

For some unholy, around 2004, reason I wrote a template library that encoded all of the crystallographic groups as integer template arguments; I guess the idea was to allow automated mapping of any point in the unit cell to its canonical ce

I worked with a guy — he's long deceased — whose doctoral dissertation was for missile guidance systems back in the 60s. The title was something like "supersonic ballistic landing trajectories for light civilian aircraft"; si

My first advisor would write code like this: std::vector<float*> myVec; myVec.resize(1024); for (int i = 0; i < 1024; ++i) myVec[i] = new float(0); There were no `delete`s or `free`s anywhere in the codebase. I a

A guy at work has a Ford Ranger EV (I think it's the '97?); he's upgraded the battery & the charger. It'd be my ideal vehicle if they were produced, again.

Does `build.rs` build the project? One of my favorite (Big Corp) code-bases just had a single C file (build.c) that did all the dependency tracking, like, Make, but in some nicely written (easy to understand) C code. The C file started with

I disagree that it's clickbait-y. Diving down from Python bindings to ucode is ... not how things usually go. Doubly so, since Python is a very mature runtime, and I'd be inclined to believe they've dug up file-reading Kung F

Texas idles a bunch of wind, but also has desperate need for immense amount of fresh water — which simply cannot be met with falling & ground supplies. The obvious solution (pitched by GW Bush?) was: wind power for gulf desalination.

Dang ternary operator. I wish ternary was "open": X ? A : B : ... Z; Where the value of each expression counted down from A..Z, ie, of there's 8 limbs, then A is 7, B is 6, ..., Z is 0.

Larger integers in continued fractions mean you get 'more information' out of the limb. That means not only is Phi "1s all the way down" it is the continued fraction that converges the slowest . If you've ever used

My question is which random walk!?

by thechao 3y ago
Honestly? Well written C++, IMO, should look like C, but with alien builtins from the future. Once C++ gets really good ad hoc memory & resource tracking, you still have the harder problem that resource acquisition is a performance suck

To paraphrase Terry Pratchett's version of this: "the intelligence of a group of people is the intelligence of the stupidest member of the group, divided by the number of people in the group".

LLM's can't gut a fish in the cube when they get to their limits. On a more serious note: I think the high-level structuring of the architecture, and then the breakdown into tactical solutions — weaving the whole program together

Pi is the scaling factor of the diameter of a circle to its circumference; there's an infinite set of such scaling factors: one for each ellipse (the circle is a special case). I wonder which/what sort of infinite series arise fro

I like this idea — I think we should tax consumer fuel based on its CCS; so, about 2$/gallon. I don't think that'd happen any time soon...

This is the space-filling curve we used for the last-level (4x4/16x16) tiles in the very early Larrabee work. It's a great curve!

For the same class of car Y is in, it's comparable in price to an ICE. But there just aren't any 15–30k$ EVs for purchase. OTOH, my TCO for my Y is way better than Tesla represented. It's so good that it comes close to lettin

How did you determine that? Could you link to a preprint or a publication where you make your argument?

This fallacy always reminds me of the "Jonah" sequence in the "Master and Commander" movie; or, any of the witch tests used by Monty Python.
