I would suspect it's some average of many points that the control systems try to track, because the rocket is not a point, and the press wants to quote a single easy number.

I'd expect that the rocket has a ton of sensors, and a ton of passive and semi-active tracking devices all over the body.

E.g. I'd put a bunch of NFC-type responders in a number of key positions, responding at different frequencies. Then a typical sweeping-frequency radar pulse would activate them all, and the response time and the Doppler shift would tell about positions and speeds of many points on the rocket. I'd do a similar thing with reflectors and IR/optical tracking.

All these points should follow some reasonable trajectory for some point the top of the rocket, near the chopsticks, would move towards some desired catch location point. Probably this motion is where "with precision of whatever cm" relates to.
Exactly. I didn't start coding until the '80s, but even at that point I was writing a lot of assembly code. I don't do that anymore. Each decade that I've coded I look back and see that I've moved up to higher and higher levels of complexity over the years. I was skeptical of AI coding, and I still am. But I've seen that it is capable of writing single line expressions quite well, and if the function is well scoped enough, it can even write full functions occasionally. My favorite use of AI is as a rubber duck, for me to bounce my ideas off of before I actually write any code. I expect it's capabilities will get better and better over time as everything does. Having The AI code these smaller bits allows me to focus more on gluing the bits together, just like I've done for the last 10 years with all the open source libraries that are available these days. I don't mind that I forgotten how to use the Lisa assembler for my Apple ][. I'm happy to keep forgetting stuff if I keep working on more and more complicated projects.

Found a rather... skeptical take (I'd argue it's more of a takedown)[0]. A bit crazy how far off the math is from viability, for a company that someone actually invested money in. Impressive salesmanship though.

Design and usability are skills that take years of practice to mature. Its something vaguely akin to interior design. To learn that I would recommend reading books about visual design and taking art classes.

To start you need to learn how the code works. But about the code you must first make a very deliberate decision:

* Do you want to learn this for yourself?

* Or, are you looking for employment?

If the goal is employment then if you have a Java background learn Angular, otherwise learn React. They are massive frameworks, so its really just a matter of using the world's largest tools to put text on screen. Watch videos online. Be prepared for a lot of boring instruction that feels like copy/paste.

If the goal is to learn this just for your own personal use then don't even bother with the framework nonsense. Its an inch deep just to people under-qualified people into the workforce and will become all consuming. Instead learn the event model for interaction, accessibility for how to write the markup, CSS how to make it pretty, and the DOM for how all this works together. Its more complicated than it sounds to get started, but once you achieve the smallest level of comfort its astonishingly faster to learn than the framework nonsense, because the framework nonsense is much larger than the things it layers over.

>obviously when they refer to loose coupling, they're refer to that between interface and hidden states/implementation of object.

Right and I'm saying it's the tight coupling of Objects themselves that's the main problem.

>It's very easy to deliberately miss the point and complain about the "tight coupling" that, by design, prevents messages to be sent to/called upon invalid states,

More like you missed my point. You should avoid coupling logic and state as much as possible period. OOP encourages this. You have one state called A, and A has 20 methods attached to it. Boom now All methods and A are tightly coupled.

At most one should have only a simple setter and getter on A, and all the transformational logic be pure functions and decoupled from the changing of state.

Oh and you can use type checking to prevent logic to operate on invalid state.

But better calculator does revolutionize math education. Math is about problem-solving – if I can use tool that speeds up the boring parts (those that can be automated), I can focus on what really matters.

What about reverse?

Is this really that dire? Comment from the GitHub issue:

"Thanks for sharing your concerns here. We have been progressing use of our SDK in more use cases for our clients. However, our goal is to make sure that the SDK is used in a way that maintains GPL compatibility.

the SDK and the client are two separate programs

code for each program is in separate repositories

the fact that the two programs communicate using standard protocols does not mean they are one program for purposes of GPLv3

Being able to build the app as you are trying to do here is an issue we plan to resolve and is merely a bug."
Yes, that's correct -- I'm in the USA, and not in Europe or Africa. What is your point with this? ARIN has, of course, delegated my assigned IPv6 network to my ISP; you do realize that this is SOP for ARIN?
If the outcome of a system is biased against people with darker or lighter skin, it's obviously racist and should be adjusted or eliminated.

How would you explain to a UI/UX designer how to do the data and BE work that you do?

As someone who has been a hiring manager for both roles I would suggest that they are reasonably different skillsets and personalities and not sure there's a high degree of overlap. If you fall into one camp I think it's better to hire for the other than to try to do both, assuming you are trying to achieve any kind of higher-order quality of work product.
Whatever "finite set of symbols" humans use to communicate is not the finite set of symbols that form letters or words. Communication isn't discrete in practical sense, it's continuous - any symbol can take not just different meanings, but different shades and superposition of meanings, based on the differences in way it's articulated (tone, style of writing - including colors), context in which it shows, and context of the whole situation.

The only way you can represent this symbolically is in the trivial sense like you can represent everything, because you can use few symbols to build up natural numbers, and then you can use those numbers to approximate everything else. But I doubt it's what Chomsky had in mind.
Well, to be fair, the engineers working on this system have been thinking about the accuracy this whole time even if you haven't. Even on the first go, it still had to land on a relatively small pad floating in the ocean.
Are the reactions extreme? You're effectively weighing convenience against fatalities. It would seem to me that the reaction is rather reasonable.

Neither judgement changes the fact that the reaction itself definitely makes DOS possible, of course.

I imagine the reason it isn't more common is that the punishment for making terroristic threats tends to be quite high (especially against airports), so you need to be very certain you won't get caught doing it.

Do you know if compilers are smart enough to return 04 even on big-endian architectures nowadays? For some reason I'm under the impression that (at least clang and gcc) are able to change this from "first byte in x" to "least significant byte in x" but don't actually know why I think that. Maybe embedded compilers typically don't?
Yes, but the nightmare is that we can't assume that children won't have guns on them.

That's gRPC, which luckily isn't the kind of RPC that a lot of computer scientists don't like, just like the Object Oriented Programming in Rust isn't the kind of OOP that a lot of computer scientists don't like.

There's a client library to install, or setting it up yourself if you'd rather not install a client library. Installing a client library makes it feel RPC-like, but not moreso than a JSON client library.

You're doing a thing here where you're equating "Democrat" with "liberal". That's less true than people think today, but it wasn't even a little bit true in Vonnegut's heyday. It isn't perfectly accurate to say we had four political parties in the 1960s (liberal and conservative Democrats, liberal and conservative Republicans) but it's not far off. The ideological sort picked up in earnest in the mid 1970s, and wasn't a dominant force in politics until the election of Reagan. Prior to Reagan, the Republican party platform was open to abortion!

Chicago under Daley (and long before) was deeply segregated (it still is). But Daley's was a conservative government.

I think the moral of the above story, although we are loath to admit it because it's so stupid, is that cheap theatrical security measures actually work surprisingly well. Whether it be $5 Master Locks, the deadbolt on your door, easily guessed passwords, or even DRM. No strength against a determined attacker, but they do mostly "work." Even a stupid password like "p@ssw0rd" prevents 98%+ of attacks compared to just a hypothetical password-free "Log in as Jake" button. If it stops 98% of casual attacks, it can be simultaneously stupid and yet valuable.
ByteDance intern fired for planting malicious code in AI models
I'm not saying 10gig itself should have been range-limited. I'm saying if the reason it was expensive was cable limits and transmit power, both of those can be solved by cutting the range. And if cutting the range could have given us cheap fast connections 15 years ago we should have made it a variant. It could have become the default network port, and anyone that wanted full distance could have bought a card for it.

Instead we waited and waited before making slower versions of 10gig, and those are still very slow to roll out. Also 2.5gig and 5gig seem especially consumer-oriented, so for those users a cheap but half range 10gig would be all upside.

And 40gig can't reach 100m on any version of copper, so it's not like 100m is a sacred requirement.

The word “bureaucrats” is funny. Why is it in the title? It seems to be used only when people want to cast a negative light on people employed by governments.

I don't understand why authorities even respond to bomb threats at all. If your security procedures are sufficient to keep people from bombing planes, bomb threats are irrelevant. If someone intends to bomb a plane, they don't announce it, making bomb threats doubly irrelevant. An institution getting a bomb threat is about as consequential as someone threatening to kill you in a Youtube comment.

That's never going to happen. Probably because it doesn't make any sense. What's a change in writing style ? Who's measuring that ? And why is that an indicator of cheating ?

>However this was never my point. My point was that cheaters wouldn’t bother training on their own corpus. You keep pushing the conversation away from that.

Training is not necessary in any technical sense. A decent sample of your writing in the context is more than good enough. Probably most cheaters wouldn't bother but some certainly would.

Funny, when I was a software developer I thought the same thing.

While there have been a few developers I have worked with who were total stars, most of them were distinctly average (unsurprisingly) and lacked basic curiosity. Even of the great developers, there are very few I would trust to do anything other than write software.

The other thing I have noted over my career is how developers consistently underrate the skills, experience and intelligence of non developers.
My IANAL understanding is that the "may be used for" is interpreted quite liberally when it comes to these sorts of laws.

The problem with that statement is what exactly does "in a way that maintains GPL compatibility" means, especially since they plan on moving more functionalities into the proprietary code, so the two "separate" components will be increasingly coupled together.

I'm not a lawyer, but I'm quite skeptical of the outcome. Is it really going to produce a valid GPLv3 licensed client? To me, it seems like the whole thing is just going to be a combined proprietary + GPLv3 license, which will contradict itself.

But again, I'm not a lawyer, so my understanding of this might be way off.

If it's positioning relative to the chopsticks, I'm sure it's possible to know where you are within a centimeter, even with all the rocket exhaust flying around. That's what DGPS is all about.

It's still wildly un-nerving to me that there's no publicly stated option other than the chopsticks for landing(edit: some future passenger craft). Imagine if you've got enough fuel to avoid slamming into the ground, and a nice big ocean, or a lake sufficiently deep... couldn't a water landing happen and let future passengers survive?

Control error is defined as the difference between desired value and measured value. So this is pretty good?

Even if they use some crude method to obtain position (e.g. gps), they can still easily refine that using e.g. triangulation using cameras around the landing platform.
The Paradigm Shifts in Artificial Intelligence
As someone recovering from back pain from a car accident, back pain (or tightness) often just means there's a weakness somewhere, probably at or anywhere below that location (could be tight hips, even ankles).

It's finding that weakness that can sometimes be the hard part, but deadlifts use the whole damn back so they're great to cover that area.

That being said, the body loves to try and compensate, so I didn't find proper relief with home workouts (and often just aggravated things), I needed all the gym machines to properly isolate muscles so my body wouldn't try and cheat. Trying random machines is also a great way to identify weaknesses.

> What do you mean by a "sound typed language".

I mean that if the type checker concludes than an expression or variable has type T, then no execution of the program will ever lead to a value not of type T being observed in that variable or expression.

In most languages today, this property it enforced with a combination of static and runtime checks. Mostly the former, but things like checked casts, runtime array covariance checks, etc. are common.

That in turn means that a compiler can safely rely on the type system to generate more efficient code.

Java intended to have a sound type system, but a hole or two have been found (which are fortunately caught at runtime by the VM). Go's type system is sound as far as I know. Dart's type system is sound and we certainly rely on that fact in the compiler.

There is no contradictory information as far as I know, but many people seem to falsely believe that soundness requires zero runtime checks, which isn't the case.

A former employer of mine inadvertently did! He wasn't asked to complete FizzBuzz, but I am confident he couldn't answer it as I worked on the same team as him. He was a very charismatic individual who always "needed help" from team mates on all tasks, no matter how small. He managed to collect a salary for 6 months. Some time after he was let go, the police called my employer enquiring after him, and we learned he was a conman with outstanding arrest warrants with no prior SWE experience at all. The name we all knew him by was just one of many aliases.
