If I'm correctly understanding what you mean, I'm fairly sure that's a deliberate optimization/design choice.

In the real world, a spacecraft or other object in orbit around Earth is also being constantly influenced by other celestial bodies, especially the sun and moon. Over short timescales this causes the spacecraft's orbital parameters to slowly drift; over longer timescales, it means the long-term position and fate of an object is chaotic and unpredictable. The behavior near the "boundary" between two spheres of influence is just a situation where these perturbations are more noticeable.

KSP only implements two-body physics, so a spacecraft is only affected by the gravity of one celestial body at any given time. This allows you to put something in orbit and know that it will stay there without you needing to constantly check on it and perform stationkeeping.

It's also the key simplification that makes "time warp" possible, since two-body orbits have closed-form solutions. To implement time warp with many-body physics, you would need to either keep the integration step size the same and drastically increase the amount of computation, or increase the step size and suffer from extreme inaccuracy, causing objects to crash or fly off into space.
"Global analysis" is specific compiler optimization terminology. It refers to analysis across so-called "basic blocks" (also compiler terminology). See here: https://web.stanford.edu/class/archive/cs/cs143/cs143.1128/l...
> revolving around the idea that the act of coding was the expensive part rather than the application complexity.

I just can’t wrap my head around this idea. If the act of coding isn’t the expensive part, then why should I have to spend so much effort coding and why can’t my effort be focused on the application complexity?

I agree that UML and past visual programming environments weren’t doing a good job of splitting these concepts, but I don’t buy that this means it’s impossible to split this.
The correct answer for that is crf 22 or so plus a speed preset tolerable for your hardware. The presets come with x264/x265/ffmpeg.

There's zero reason to care about Blockstream Bitcoin. If you want the original design of Bitcoin, that's called Bitcoin Cash now. But there are so many alternatives to choose from. Blockstream Bitcoin has the largest market cap, but literally no other advantages.

Those C++ bad, complex, unsafe etc. etc articles are starting to get boring.

If one wants to shoot him/herself in a foot it is fine. C++ offers countless possibilities.

It (and plethora of libraries) also offers quick way to write sophisticated and performant applications without much fuss.

Make your choice. I personally use C++ to great advantage and find it very productive and safe. And while being good programmer / designer I am not a C++ expert. Far from it.

Or use language of your choice. Nothing is wrong with it. We do not have to live in the world where "there can be only one".

The parameters for x264 present everything you need in the correct different dimensions (speed, compatibility, quality, type of content like animation/film/screen recording). The problem is solved, the issue is people built frontends on top of it and present the options in a wrong way that ruins them.
It's actually much more interesting than this person describes.

It turns out this company makes machines for lots of other fast food chains but McDonald's is the only one with this problem, and it seems to be intentional to allow Taylor to milk mcds franchisees.

It gets stranger when you realize that the majority of the problems seem to stem from the manufacturer purposely designing their machines to prevent their customers from operating them properly to inflate the need for maintenance .. even going so far as to silence an invention that allowed the machine to display human readable error messages to allow the operator to know things like if the hopper was too full to run the cleaning cycle.
Bounds checking, dynamic dispatch is more expensive, wasm semantics have no undefined behavior to exploit for optimizations. And there is bloat in the process. I’m sure losing information effects things as well

Study finds ride-sharing intensifies urban road congestion
Interesting it says that all other participants in later studies needed viagra, and they were the only ones who did not. They apparently were so happy with one another, they needed no special tools to get the job done while in a room with a lot of noise and other people, perhaps. MRIs are noisy things, and I find their comments interesting.
STL and OOP are orthogonal, e.g. you can use STL without ever using the concept of inheritance.

Boost is too popular imo, and many people take it for granted when using C++ that it comes with this nice utility library to complement STL, kind of like another python package, no big deal.

From what I've seen on multiple projects it creates an explosion of poorly understood (and often poorly implemented) dependencies which leads to maintenance nightmare, memory leaks and bugs, performance issues and production outages.

If you can avoid using an external dependency such as a gigantic library full of experimental features created by thousands of C++ enthusiasts avoid it at all costs. as it tempts the team to use it left and right when it's not really needed, just like templates.

Templates, if used without strictly complying to the KISS principle can get unwieldy, full of nuanced, intricate and unnecessary abstraction, and make it hard to understand and maintain the code

C++ is a giant language and its use on a particular project has to be very tightly constrained to a very minimal set of features and dependencies.
I find it odd that this is a kind of mathematical article but doesn’t use the existing terms in codec literature - why does it say “cost/benefit” instead of “rate/distortion”?
This only goes so far, though, with frameworks. In my experience, the vast majority of people that make claims about a particular framework do not understand the abstractions they are building upon. In fact it is sufficiently reliable that I have found this to be an excellent hiring signal, to probe how well a person understands the abstractions in frameworks they use, but also to probe how they diagnose and fix holes in their own knowledge.

From interviews, I don't think Thiel is, or ever has been a patriot. Nor do I think he ever pretended to be. He backed Trump because he's bullish on the nation-state, and his aims of greater self-sovereignty are in opposition to a more homogenous and coordinated global order.

Internationalist America has systematically crushed anything new that might pose a threat to the global order, something autonomous floating nations might do.

Bilateral America's self-interested realpolitik approach under Trump was much less interested in the state of the rest of the world, provided it gave the nation what it wanted (in theory, ofc. The foreign policy establishment did everything it could to maintain business as usual).

Speakers already exist that do what you describe, although there is a physical limitation that ultrasound has to be used achieve extreme directionality, and it is distortion that is audible.

IIRC, the boy version was Digimon. Basically the same toy, but you could battle them.
Yeah, I guess you really just need a jump function and then streams are just partitioning the space by whatever distance.
Well, how about beacon.

It also happens that most tlds with beacond are available.

Cursory search on GitHub says you would be pretty alone in your use of beancond as well.

> You allocate a memory arena when the HTTP request comes.

The per-request-arena concept is one of the most powerful and IMO underappreciated tools out there for dealing with memory-lifetime issues. I've used it or advocated for its use at multiple jobs and projects, quite successfully, even for kernel code. Windows NT uses it in IRPs. Network code in both BSD and SysV did something pretty similar, at least in the long-before-Linux days. It's tried and true. Having a clear moment when things should be freed and an equally clear description of what those things are is wonderful.

That said, even games and network servers and storage drivers often have other complex data structures not related to individual requests. It's usually not hard to come up with rules for each of these, but the rules forced on you by something like STL might not be as convenient, performant, and/or verifiable as those you come up with yourself.

I hope that some day programmers will stop using memory-unsafe languages except when they really need to, and that when it is necessary those languages will give them the tools to solve those problems themselves instead of pretending they're already solved. They're not. Rust's borrow checker plus Zig's arena concept plus a couple more pieces might actually get us there. C++'s feature salad never will.
UML - Unnecessary Management Lingo. - @iamdevloper

UML - I know next to nothing about UML - but what I do know is the language was invented first and then people came around and tried to give semantics to the language. Well, in other words what that means is that the language was invented first and it really didn't mean anything. And then, later on, people came around to try to figure out what it meant. Well, that's not the way to design a specification language. The importance of a specification language is to specify something precisely, and therefore what you write - the specification you write - has to have a precise, rigorous meaning. - Leslie Lamport

UML: a language that was invented first and then people came around to try to get semantics. - Leslie Lamport

UML: fuzzy pictures of boxes and arrows. - Leslie Lamport

People use UML, things like UML, to model programs, but it's not clear how to translate them in to sequences of states, for concurrency. If you cannot translate them in to sequences of states, it means you don't understand them, and it may mean that there's nothing there. You know, there are lots of people selling snake-oil, drawing boxes and arrows that make you feel good, but ultimately have no real meaning. If something is really meaningful you should be able to express it in mathematics. - Leslie Lamport

The first analysis was done by Zoe of phzoe.com, then apparently completely independently reproduced and confirmed by another researcher. YouTube has openly floated the idea of not displaying dislikes, something that has been previously discussed on HN. So it seems like they are manipulating the data, and that it is this obvious, and that they're taking steps to make it less obvious now.
Here is a very nice and through paper on the subject:
"Natural Transfer of Viable Microbes in Space"
https://doi.org/10.1006/icar.1999.6317

In the abstract:
"The conclusion is that if microbes existed or exist on Mars, viable transfer to Earth is not only possible but also highly probable, due to microbes’ impressive resistance to the dangers of space transfer and to the dense traffic of billions of martian meteorites which have fallen on Earth since the dawn of our planetary system. Earth-to-Mars transfer is also possible but at a much lower frequency."
When you do that, you have to start specifying what reference-point you're looking from. And then regardless of what you choose, you get these awesomely-weird spiraling / spirograph-ing orbits in some cases, e.g. like Principia shows https://www.youtube.com/watch?v=eU-kLLeE7n0

The non-continuous flip lets them keep orbits exclusively centered around the you're-most-likely-orbiting-this thing, which makes them all look "normal" and the same. Though I would like to be able to see either option in the stock game - they both have their uses.

Pretty much. Girls had Tamagotchi and boys had Digimon.

Data-flow analysis is what I assume the author meant. Fancy word for "reasoning about behavior at a level higher than just a syntax node" (usually within a function or module, possibly within an entire program though)

Both D and Rusts compilers do it, and I'm uncertain whether Zig's does but it may too.
I don’t agree with that. At the height of tama mania everyone had one.

Usually, digi was a more complicated knock off that fit a different niche of people who like battling Pokémon.

Edit: I had both, but digi personally wasn’t all that fun and everyone did tama because it was mellow and easy. We played Pokémon if we wanted to battle.

US and EU citizens could visit most places on a whim, but leaving and staying permanently elsewhere could be a lot more difficult -- even if you were an American who didn't want to go farther than Canada. (After Trump's election, there were more than a few Americans who found that a very unpleasant surprise, for some reason.)

And as we're seeing on the US southern border right now, the rules are very, very different for people who want to pick and leave, say, Guatemala.
If you got to consume the media you bought for months/years and you get a full refund, I'd say you have nothing to complain about.

This is why concepts like opportunity cost and consequential loss exist. While your arguments here seem reasonable, it is also reasonable to argue that harm has still been caused to the consumer, if they originally had a choice of vendors to buy from, a bad one they initially chose has refunded (only) their original purchase price, but the current market price is significantly higher.

If the basic principle of awarding compensation for damages is to make someone whole to the extent that this is possible, then the consumer in that scenario does still have something to complain about. This seems particularly relevant with digital products, where copies are entirely fungible and if the consumer has lost access they previously enjoyed then this was the result of the vendor's decisions around the technology, either actively revoking the access or deleting the material somehow, or taking some action like switching off a DRM server that indirectly causes the same end result.
Anywhere in the US. Some locations are worse than others for property taxes.

I'm in a red state with relatively tame property taxes but the taxes that do exist that count inventory as property prevent us from keeping appreciable inventory. Everything is a minimum 3 week lead time to buy and produce, usually more. I am pretty sure JIT slows down the economy in general.
It also came out later? I think I had a tamagotchi in 1994 or 1995 - I think digimon didn’t show up until a year or two later.

I am confused by the article. The author cites a technology that seemingly demonstrates the concept of a "jam". But clearly, technology moved on, because all the benefits of the minidisc (re-writeability, compactness, reliable playback) were met by flash storage.

Its also imperative that the lack of enthusiasm for minidisc must have other market / human factors at play.

Also, when it comes to the iPhone Jam, the author does not spell out what is at the end of the jam.

The Internet as we know it was built on the back of someone else's free.

I am older than most of the crew here and can remember when the majority of the telnetting and IRCing we did was against .edu domains, using the disk space of a Sparc 1, sucking up someone else's bandwidth. In February of 1993, someone very much like Don Draper woke, inexplicably but smiling, with the first morning erection in years as the <img> tag was invented; banner ads slouched towards CERN to be born. NetZero told us that the Internet should be free. Email, free of expensive stamps, flew 'round the world. And Advertisers and Spammers and the Attention Economy held illimitable dominion over all.

We have paid an enormous price for the "free" Internet and that price has been hidden from us through layers of affiliates and misdirection and double-Irish. Rudderless algorithms decide whether your fame career has any kind of money associated with it and for precisely how long. When the axe descends, the only sentence can be "You have violated the ToS."
