It wouldn't surprise me. This city is corrupt as hell.

I must not be human. For factual information of this sort I just prefer the information. The story is irrelevant and usually too mundane to be bothered with

I always thought this was for two reasons: one as you say is to show the plumbing works, the other is because not passing the meconium (combination of stuff ingested while in the uterus) indicates other more serious conditions might exist

I’ve been in cat 1 and cat 2 storms. They’re awesome in their power for destruction. I’ve evacuated from a category 4 storm, which did a huge amount of damage in the city when it hit. A category 5 storm is essentially going to destroy every

EM’s vector fields formulation is fairly straightforward: it’s all curls and divergence. Any 3rd (-ish) semester undergrad multivariate calculus course is likely to cover it in sufficient depth. “Mathematical Methods for Physicists” covers

I'm American. I've been in two economic classes: dirt poor (as in, more or less homeless, when I was a child, for a bit) and now on the low end of rich (net worth in the mid 7 figure range). I've seen both sides of this inequ

This is ridiculous. Set aside the (incredibly optimistic, to be charitable) thinking that is going into the acceleration of these probes. The astronavigation itself is hugely questionable, especially with probes that aren't big enough

At 0.25c the probes would blast through the centauri system in minutes. Hardly enough time to collect data more useful than what we already can sitting here practically stationary, even if absurdly far away.

It does not have 0 performance impact, it's not rare, and in applications that are in the hot path, error handling is also in the hot path.

That "detail of implementation" is what is used by user code, e.g., `myError.As(...)` uses reflection, implicitly.

I really appreciate the lack of magic in go's error handling. I do not appreciate the specific implementation of errors in go. It's inefficient (`reflect` is all over the place) and prone to obscuring the actual "error path&q

Some tech is. Meanwhile large tech companies that are actually innovating (FAANG, near-FAANG, and FAANG-adjacent companies) are not. My comp has never been higher, and we're hiring. In the bay area.

It does take a long time, and also "real life" immersion, to learn a language deeply. It's the immersion part that Duolingo doesn't do well if at all. So it has to artificially slow down those things it does do in orde

I think the argument is generally that most applications' "complex interactions" are artificial contrivances and are unnecessary. I certainly think so.

How is SPA a simpler starting point? It requires more code and more abstractions in the client from the onset. One might argue that that complexity would just exist in the backend in an MPA, but that's not true: there is some additiona

It will come out in the NTSB report, if it's true. Though that will take quite a bit of time.

Please stop moving the goalposts. Iterating on the past is different from thieving entire designs, and you know it.

Because it demonstrates a theft of tech and design, which puts their credibility and integrity in question. Is the derivative safe (actually safe, not government-of-China wanting a feather in its cap rubber-stamp safe)? Is the derivative ac

We have yet to see if AI can produce good, new content the way humans can. I'd consider it a problem if mass-produced AI stuff makes it even harder to surface that content.

That really depends on what you mean by "machine learning system." For a business, implementing some researched algorithm and essentially using a template? Sure, it's possible. The research that goes into producing the algori

I've been to a few countries outside of Europe and the US. Obesity and lesser but unhealthy fatness may not be as widespread yet there, but they're not that far behind. Also, what some cultures consider "not fat" isn&#

Rust and Go both provide features to implement code in an OO-ish way: traits and interfaces. I just code in Rust as a hobby but I code in go professionally. The go codebases I work on at work are bloated messes of abstractions and duck typi

If your point is that the physicist should partner with someone who is a "professional programmer" ("carpenter") to do the coding, I couldn't disagree more, speaking as a former research physicist who wrote many pro

No, you don’t, unless you’re of the opinion that actual data structures with test data should not be used in a unit test.

by sidlls 3y ago
Eh, not really. Go’s philosophy around abstractions is quite poor. Duck typing begs engineers to create poor abstractions that simply reading a codebase does not necessarily lead to understanding. The bolted-on generics implementation actua

What you describe are relatively niche or uncommon uses of these algorithms and data structures. Further, the specific implementation details of a given algorithm become relevant in these contexts. Different implementations of a hashtable c

Yes, as they’re literally life-and-death in many cases. Getting a pilot license requires one to demonstrate the ability to do certain “not common but not exactly uncommon either” recovery things from memory. And different bits of those “100

Not really. There are two key traits one needs to memorize for general purpose programming: time and space complexity. Literally a “cheat sheet” with a list of order notations is sufficient to memorize.
