If only we had that kind of sanity in the US… the electric hummer is an absolute monstrosity and should never have been made IMO. I am a supporter of EV’s but, I am increasingly skeptical that legacy US automakers will ever “get it” when it

I mean, if we’re picking models to support our points, I’d counter with the Hummer EV which is 9,630 lbs. Road wear goes up with the 4th power of weight, so doubling the weight increases road wear 16x… it’s not something we should just igno

It is in the mind of consumers, yes (I have not offered my personal opinion and don’t want to, as it’s irrelevant to the point.) There has been a lot of consumer studies on this and range anxiety is a very real thing.

Begone troll. (Edit: because I noticed this too, and it got me curious, the reason for the incorrect result is that I didn't check the result of the read() call, and it was actually reading fewer bytes, by a small handful. read() is al

You're basically just gish galloping at this point and there's no need to respond to you any more. All your points about swap are irrelevant to the discussion. All your points about disk cache are irrelevant to the discussion. You

Please keep in mind the context of the discussion. A prior poster made a claim that they can read a file into memory, and that it won’t actually use any additional memory because the kernel will “automatically take care” of it somehow. This

NAT64 is just stateful NAT, exactly the same as IPv4 stateful NAT. It happens to be translating between v4 and v6 as part of the translation, but it’s no different whatsoever from pure-IPv4 NAT in this regard. You can call it “tunneling” if

Fair enough, it’s totally possible that’s what they meant. But the complaint of “every package assumes you loaded the whole dataset in memory” seems to imply the package just naively reads the file in. I mean, if the package was mmapping

That’s a really misleading thing to say. If the kernel already has the thing you’re read()’ing cached , then yes the kernel can skip the disk read as an optimization . But by reading, you’re taking those bytes and putting a copy of them

Coming from the Apple ecosystem, this is solved on macOS/iOS by a native implementation of 464XLAT on the device (particularly the CLAT relay part.) If you have a working NAT64/DNS64 setup, macOS can make a AAAA (ipv6 DNS) request

I’m talking about replies to other people’s comments. If someone asks you a question in a review, it seems crazy to me that you should submit your own review of your own code, complete with an approval (huh?) just to answer it. If you’re sa

GitHub seems to have no interest whatsoever in making the process of reviewing code any better or easier. It’s still essentially the same as it was 15 years ago. They introduced batched review comments well over five years ago, and still ha

Right. To elaborate on my original point, because ObjC includes C, saying "ObjC has safe arrays because it crashes on OOB" is both true and irrelevant. It has safe arrays, but that's not all it has. It also has very, very

A lot of people are asking you how it's possible you're getting deadlocks, so I'll reply to all of them here: It's definitely possible without doing anything wrong in your own code, if you're calling poorly written

We know that the webp project does use unchecked access. We know this is intentional because they go through a lot of effort to do up front bounds checking rather than at every access. We also know that companies like Dropbox, when implem

That’s not google’s webp library, that’s a totally different project. It doesn’t really matter what that project does.

A memory-safe language could have easily resulted in the same vulnerability. In this context, “memory-safe” means it does bounds checking on an array when you try to access an element. But the webp code does bounds checks up-front so that a
