I believe most of the 8bit microcontrollers from this era have no good optimizing compilers that get close to what competent practitioners achieve with assembly. I think it has to do with having complex addressing modes making the C stack f

You are arguing against a very well known phenomenon. Technical people often avoid getting promoted to management precisely because they love doing the thing themselves. Despite the higher potential for impact in a management position, losi

Doesn’t that only work on Linux? And then only for things that make syscalls? Presumably people have to trace other slow paths sometime.

The missing piece that makes it not a tautology is that two apps side by side have the same aspect ratio as one app full screen (but 90 degrees rotated)

Equivalence on what metrics? In theory what you are asking for makes sense, but I think it is very hard to actually specify what equivalent means in the context of an optimization process that needs to emit code with observably different be

Listening to eskil’s talk from the better software conference, he said in order to stand on the shoulders of giants they must first stand still. I really like that metaphor, because it basically suggests today’s apps that have sprawling una

I think you could make a case for that, especially when landing in water. Quite a few dense urban areas people might need to get to have water nearby suitable for landing seaplanes. I think you would end up creating communities further from

This! Anything unproven makes the flight certification process longer. They already have to get their electric side certified, might as well make the backup generator as easily certified as possible.

Regular aircraft are required to have enough fuel to be able to divert to the alternate airfield in their flight plan plus all the margins for taxiing and waiting for a landing clearance. If a plane is low on fuel they can declare an emerge

I am struck by the fact that arguments for or against within this thread are only about perceived safety (something hard to know at a distance) and not the substance of the law involved. Does Virginia actually have laws prohibiting unsuperv

It is quite long, but I thought it was worth it if you can find the time. Short of that I think just reading the Knuth article the quote is from might bring similar insights.

I think the theory was that when each weight will be needed is predictable, so the latency can be hidden by fetching earlier (or more likely building the data in such a way that streaming it linearly brings the right weight at the right tim

I believe the comparison is with iOS not Linux. Android is Linux after all. It’s just that most programs don’t get to run a that level of abstraction, and instead run on top of a jvm. At least in iOS the code does seem to be able to be more

what even is the alleged crime? If there was any protected IP they would be able to use the courts to sue. But that isn't happening, which suggests they know they don't have grounds. Am I missing something? Patents seem to be very

It does show a popup to that effect, but if you dismiss it you can still see the tracking info. Definitely annoying, but not unworkable.

People take much more time off during the summer in the USA than during other times of year. It’s somewhat regional, but it’s been true in all the place I have lived. Probably July is the most common month though because in some regions sch

I have definitely worked on teams that hit their stride frequently. Definitely not every project or deliverable, but often enough that people got used to it. Unfortunately that was maybe 4 or 5 years ago and I haven't seen it since.

Thanks for writing it! It was exactly what I needed to process my frustration with work today.

Of course! The article agrees with you > Real speed exists. Real speed is what happens when the work is understood, the constraints are clear, the people involved know what they’re doing, and the decisions have been made cleanly enough t

> Rockets are usually two-staged + satellites. I think that only applies to liquid fueled rockets. At a minimum the Scout family of rockets (USA) and the Lambda 4s (Japan) both use 4 stages. That is what I was trying to say above. The si

Good point! The final stage being liquid would also give them more control to fix any errors with the orbit.

No it’s just a really insulting and irrelevant thing to say.

by MobiusHorizons 2mo ago
4 stages is certainly a lot more than most rockets, but most rockets don’t use solid rocket stages. Solid rocket motors are generally much more reliable/ simpler than liquid fueled stages, but they can’t be throttled or turned off earl

I don’t think that’s a good reading of the comment you are reacting to. That comment really only says that there is already a computer in the control loop, and that that computer is responsible for the very fast responses required for stabi

People code in assembly and c and vanilla JavaScript all the time. You may not, but none of those are even that niche of skills. I’ve even decoded machine code from binary (well hexadecimal, but a raw memory dump) by hand a few times when I

Interesting analysis! It would be very interesting to see how this compares to windows on the same hardware.
