By this same metric, do you refuse to use C because the vast majority of OSS C codebases are permissively licensed? Surely you see that this makes no sense, yes? Neither Rust-the-language nor Rust-the-ecosystem are any more hostile to GPL t

I mean, it's an apt comparison, given that the Venn diagram between the pro-NFT hucksters and the pro-AI crowd is a circle. When you listen to people who were so publicly and embarrassingly wrong about the future try to sell you on the

The problem is that "division" in the context of computation refers to multiple different operations, so that we all end up talking past each other. Some people want a `division_where_zero_is_an_illegal_denominator`, some people w

Let's not dance around the issue. It's clear that the reason that the VC class are so frothing-at-the-mouth at the potential of LLMs is because they see slavery as the ideal. They don't want employees. They want perfectly sub

Yes, Apple is an ad company. Their annual ad revenue is in the billions, and climbing every year.

Prediction markets can only pay out based on public information, which means that prediction markets can only "reveal information" like this for things that would have been public knowledge anyway. And insiders are always risking

"High variance, slightly-negative EV shots on a long time horizon" is a gambling addict's way of justifying the old adage, "sure, we're losing money on each sale, but we'll make up for it in volume!"

The output of /dev/random doesn't have meaning, but that doesn't make my kernel a nihilist.

At no point in human history has C been the best language for beginners. C was, like Javascript, hacked together in a weekend by someone who wished they could be using a better language. It was burdened with flaws from the outset and consid

Yes, defer is absolutely a form of hidden control flow, even if it's less egregious than exceptions.
615.
by kibwen 8mo ago
Defer is also hidden control flow. At the end of every block, you need to read backwards in the entire block to see if a defer was declared in order to determine where control will jump to. Please stop pretending that defer isn't hidde

No, RAII is one of the primary improvements of C++ over C, and one of the most ubiquitous features that is allowed in "light" subsets of C++.

If you're teaching them to write an assembler, then it may be worth teaching them C, as a fairly basic language with a straightforward/naive mapping to assembly. But for basically any other context in which you'd be teaching

The vast majority of Rust code out there doesn't use the `unsafe` keyword at all, and the vastly smaller amount of unsafe code that exists allows for focused and precise testing and verification. You really have no idea what you'r

> both of these are not the case in practice though No, people routinely write Rust with no third-party dependencies, and yet people do not routinely write C code that is memory-safe. Your threat model needs re-evaluating. Also keep in

But this is irrelevant. If you're afraid of third-party code, you can just... choose not to use third-party code? Meanwhile, if I'm afraid of memory corruption in C, I cannot just choose not to have memory corruption; I must inste

I still wonder if it wouldn't have been better to let each digit be represented by its exact value, and then use the high end of the scale rather than the low end for the control characters. I suppose by 1970 they were already dealing

No. Apple makes money from subscriptions, and Apple controls the app store with an iron fist. In a hypothetical world where the price of apps falls to ~free, Apple will just ban free apps in order to recoup that revenue. Hell, if you think

No, this is silly. You can look at the availability and maturity of toolchains, the rate of release of projects written in that language, the rate of release of books and learning materials, the rate at which universities begin teaching the

I'm not expecting to convince you of this position, but I find it to be a feature, not a bug, that Rust is inherently hostile to companies whose business models rely on tossing closed-source proprietary blobs over the wall. I'm fa
