You’re forgetting about derailment... which can slow trains down much much faster

I have no idea? Brain fart. doctors also get paid by the procedure, so charge less for simple office visits (it’s complicated because of how medical billing works)

by bodhiandphysics 4y ago
You almost certainly pay far more than 68 an hour for a doctor! (How long are you actually with the doctor?). Plumbers and mechanics are paid at a significantly lower rate than doctors and lawyers!

Note that this is the announcement of a settlement. Nvidia agrees to pay 5.5 million, agrees to state the risk, and doesn’t admit to fault. No one is in serious trouble... nvidia should have indicated the risk, and didn’t... (probably bec

It’s annoying when parsing c. Also the situation is worse in c++ since * can have side effects!

I like to joke that the world would be very different if we had Platos lecture notes and Aristotle’s dialogues (which were famous in antiquity)

by bodhiandphysics 5y ago
Homer is an exception to this! There are almost a thousand Homeric manuscripts. There are 7 Plato manuscripts. Aristotle was significantly more popular, with almost 300 manuscripts, almost all from the west, and due to Byzantine original

No one was particularly interested. People in Constantinople didn’t even know what manuscripts they had! (The major extent Plato manuscripts fir instance are from the 9th-11th centuries, the so called Macedonian renaissance). Westerners be

I don’t want to use Fortran! Julia is lovely

Low level linalg... implementing solvers using openmp and CUDA
101.
by bodhiandphysics 5y ago
Finanally, c++ is the only language I would ever want to do linear algebra in, or for that matter, many graph algorithms. Rust is adding features to make it useful for linalg, but it’s not their yet. Linear algebra is important!

by bodhiandphysics 5y ago
I should note that writing data structures in rust is also a fraught business! In practice, that’s just a property of languages that don’t have garbage collection. Exception safety is a serious complication in c++! Exceptions were a mist

Because it needs to repeat messages more till you get a clear message through

Using c on a word machine is just a bad idea.

The most important non x86 arch is aarch64 which is in fact byte addressable (more so than x86)! So is mips64.

Unfortunately, I need cuda (for now)

It’s so annoying!!!! I work in computer graphics and scientific computation and it’s getting hard to get gpus with adequate double performance.

Not at the ISA level. Programmers don’t have access to the smoke and mirrors besides some cache management stuff

Planting trees is more expensive than you think! You have to buy the land, maintain it, actually physically plant the trees ( which is rather labor intensive). Plants are a relatively low density place to store carbon ( compared to say car

Probably not... but both ways are fine.

Lots of programs malloc a lot of memory, and do nothing with it for a while. This allows the os to wait for a low load time to handle memory allocation.

The cpu bus is what’s important. Bus addressing us at the byte level

Your program does nothing! It’s the reduction stage that causes the bottleneck

One of the great things about icon is the wonderful book on implementing it! It gives a lot of detail into how interpreters work under the hood

Matlab isn’t umm... no code! It’s a programming language! Stimuli I is a bit more no Cody... but it’s effectively a visual programming language

Not really? JavaScript doesn’t have conses so it’s not very lisp like in practice. What is gets from scheme is closures with lexical scoping (real closures). It’s closer in style to self, but js is textual instead of image based so that

Smalltalk is a lot more than it’s minimal syntax! The language is unusual without its associated libraries, and they are often extremely concept heavy

I meant the infinitely massive box of physicists dreams. Translational symmetry is broken by the boundaries of the world

by bodhiandphysics 5y ago
Sure! A ball in a box is a closed system the doesn’t conserve momentum.

by bodhiandphysics 5y ago
Newton’s third law is just the conservation of momentum... and lots of interesting systems don’t conserve momentum!
