I don't mean to minimize anybody's work, I'm genuinely curious about why it can't be done. Like, what's stopping me from making a compiler that optimizes tail calls? For instance: the C and C++ standards have very s

by OskarS 4y ago
I don't quite get your point here. Suppose I write a compiler to compile Scheme to WASM. I would have write it so that it does proper tail calls, otherwise it wouldn't be Scheme. What's stopping me? Would the browsers not r

I think having some diversity in the Rust compiler space is an excellent idea. The rustc monoculture is really bad in the long-term, having multiple compilers allows for creating a much more robust standard (so that implementation bugs does

They've actually radically redesigned the aerodynamics of the cars this year to address this exact problem (using ground effect instead of relying so much on wings for downforce). It's had it's own issues (there have been rea

by OskarS 4y ago
My guess is probably that it's performance issue. You would have to do a `if (addr == 0) trap()` branch on EVERY memory access in the WASM runtime, which is not free. I guess it would still has to do some kind of bounds check to see th

C doesn't have "private" functions in that way, what it has is "static" functions, and this is indeed the biggest limitation of doing this kind of amalgamated build. If you mark a function as static, it means that h

It's absurd to claim they're doing this for any other reason beyond deceptive marketing. It's like an advertising version of a dark pattern: a decision which has a sheen of reasonableness, but is clearly designed to deceive a

I can totally see the line of reasoning that ended up with this decision. It was the wrong decision, but I absolutely can see how smart and competent people could've arrived there, or missed the reasons why (for instance) promising poi

The fact that the STL api leaks these kind of implementation details is such a shame. Multiplied globally over all users of unordered_map, the amount of CPU time that has been wasted because of that decision boggles the mind. Has to be one

Yeah, I hadn’t heard about this ”daylight” thing either. I’ve been nearsighted since I was a kid, and back then people said I got it because I read to much, focusing on things too close to my face. I thought that was a pretty fair trade-off

I’m guessing a linker like this is also a VERY extreme case when it comes to mmap’ing a huge number of files. For most software, it’s just not that big of an issue.

I’ve had similar issues with HomePod when it comes to other apps (e.g. playing podcasts from Overcast using AirPlay), but the Apple Music integration has never been a problem, that has always just worked. Siri sometimes gets confused about

by OskarS 4y ago
The integration with HomePod is very nice, I can just go ”Hey Siri, play Tom Waits” or whatever. Maybe that works with Spotify, I dunno, but the integration with Apple Music is obviously seamless, it just works.

Excellent news! The energy consumption required by proof-of-work blockchains is simply unacceptible, and it’s perfectly appropriate to adress it using new laws. Hopefully other states and countries will follow suit.

Yeah, I agree, it's a shame that there isn't a better mechanism to pay for CLI software. I think a lot of developers would just refuse non-open source CLI software, but that really shuts down what could be a healthy market. Don&#x

I just use recentf for that. My buffer list contains everything in the recentf (this works with buffer list replacements from both Helm and Ivy). Makes it trivial to open up any file I've had open before. Opening all buffers you'v

> All the CPU has to do is update that mmap'ed buffer with new position information Doesn’t even have to do that, this is child’s play for a compute shader. The CPU can go take a 16 millisecond nap and let the GPU do all the work.
