Let me X-plane: Boeing R&D unit sheds rudder, ailerons, flaps for DARPA project

Re: History lesson

Many things were once "too hard" or "theoretically possible but not realistic". Nuclear reactors and microchips for instance.

Materials science and aerodynamic refinement are both areas which continue to move onward at more than a snail's pace - the latter especially due to the computing revolution (more well known for its impact in areas like F1).

So maybe they have cracked it this time... or maybe it's like Fusion, always just around the corner (although now even that might happen)

>>I'll give him the benefit of the doubt that there is a political or corporate requirement to use marketing droid speakings in presentationisationings.

When someone who is far, FAR more knowledgeable than you and has been deeply immersed in a niche industry with its own terminology for decades uses language you find unusual, we can all agree ONE of you is showing their ignorance.

Language doesn't just evolve over time, it evolves in weird ways in specialised areas. In IT we refer to a PC as "a box". It's not a box. Often it's not even in a box (it's in a rack). You're just making yourself look silly criticising world-renowned senior experts on their word choice.

OpenAI is developing software to detect text generated by ChatGPT

JDX Gold badge

Re: Sources

I actually asked ChatGPT a SK question "Who is ted brautigan" the other day. It gave me a believable but incorrect answer, referencing him as a character in totally the wrong book.

I asked again today, and it gave another believable answer which is partly correct:

Ted Brautigan is a character in Stephen King's science fiction novel "Hearts in Atlantis". He is a telepath who has the ability to read minds and has fled to the United States to escape persecution for his abilities. He befriends a young man named Bobby Garfield and helps him to understand and develop his own telepathic abilities.

That last part is simply untrue. It sounds exactly the sort of thing you would read in a SK novel but Bobby has no special powers and Ted never teaches him anything of the sort, Ted's powers are mysterious and only explained in a separate novel where he returns.

It's a great example of the dangers of GPT. Even SK fans might not spot the error because it 'sounds right', and could easily miss detection if copied.

Re: Nice way to make profits

Except they don't sell it.

They are producing a tool, that's all anyway. It's not cynical for the same company to sell scissors and tape/glue.

So know the chatbot has to learn to evade detection

If we feed the results from the detection agent back into ChatGPT can it not train itself to produce output that will evade detection? Isn't that one of the main points of a ML chat-bot designed to appear human, that it is constantly learning how to be more believable?

Could be an interesting arms race, except these things learn in hours rather than months.

RIP Fred 'Mythical Man-Month' Brooks: IBM guru of software project management

JDX Gold badge

Re: Man-month

You can buy "concrete accelerant" which literally makes it set faster.

"you can't speed this up with more people" is sometimes true, and sometimes not... you can speed up laying the concrete and laying the bricks but (smart alex comments aside) the concrete takes a fixed time to set.

However often a seemingly monolithic task can be decomposed into things which may be done in parallel if you take time to analyse and understand it. In software that might be via unit testing, in building well maybe you can organise things so that while the concrete sets, other work can be going on instead of the project stalling.

Developers are not typically (as a developer) very good at planning this, and tend to be sceptical that anyone else is. But a good manager/analyst/architect can.

JDX Gold badge

Re: Man-month

That's an interesting point I had never considered, that those brought up in modern paradigms simply don't work in man-months because Agile approaches deliberately avoid it.

Of course then many fo the other extreme "we can't plan or schedule anything" but that's just the pendulum swinging.

JDX Gold badge

Re: But Agile will fix everything!

If the project manager is trying to control every step, that's not Agile. Agile is specifically about all the team being involved in running the project based on them being the ones who know what's going on.

Twitter engineer calls out Elon Musk for technical BS in unusual career move

JDX Gold badge

Re: So what happened to this freedom of speech thing then?

Free speech does NOT mean you do not face consequences. If you take out a newspaper advert calling your boss a **** then you can expect to be fired. It's unprofessional.

Freedom of speech means you have the right to say it, not that you get to insult your boss to the public and avoid any reprisal. Surely anyone can see this. If you tell your boss they are a **** at work you can expect to be fired, and that's far less public.

Re: Firing all the wrong people

We don't actually know the developer knows what they are talking about, only that they have poor decision making.

"there's lots of unused features" is not a reason code is slow. Code you don't call makes the design messy but doesn't take any cycles.

There are not zero RPC calls, there are lots of API calls going on (presumably REST but could be websockets or something else). The technical distinction is pretty slim at best and the developer would know this.

JDX Gold badge

REST is a way of remotely calling a procedure over HTTP - not a particularly efficient way of doing so. Take thoe 3 letters and juggle them up and you might get RPC out.

Re: Unfortunately not peer reviewed

If a news source chooses to report on a paper before it is peer reviewed or fully published, that's not really the fault of the people doing the research?

If you want hard news, read the scientific journals who wait until things are reviewed to report on them. Just because something isn't peer reviewed (yet) doesn't mean it is not interesting though.

Scientists love being able to make quick calculations which help guide them where to focus their time for the more in-depth ones.

Re: Art class

Even in human circles, trying to make work you can pass off as a famous artist is considered poor form, so no it isn't different in that regard.

A human who tries to create art in the specific style of another has to put in a lot of work. They must study their muse's works and learn in great detail the exact style and technique of the artist, before spending a great deal of time honing their skills. This is very different from an AI training set, so that's "reasons".

A typical human student does not however try to do that. They learn from great artists and borrow techniques which they apply to their own passions, or they blend styles from multiple artists or come up with something totally new.

New measurement alert: Liz Truss inspires new Register standard

Currency units are lacking

I was hoping to calculate my daily energy use in approved Reg units but the lowest £ value that receives a non-zero conversion in any other unit is £10,000 and even now, my energy cost is not that high.

We need a currency unit which is comparable or significantly lower than the pound, or the converter needs to have a better resolution such as nanoPogbas.

Waxworm's spit shows promise in puncturing plastic pollution

JDX Gold badge

Re: Terms and conditions

>>Unless washed ashore they're there to stay.

Not really. There are already projects trialling which capture plastic from the ocean. It tends to congregate in certain areas which can be effectively targeted

This won't get it all and doesn't help with tiny fragments but a lot can be done even if only the easy pickings are taken. And plastic is constantly being washed up so if we can stop more getting into the system, over time things will improve.

Being more speculative, organisms which eat plastic might even be introduced into the oceans but this seems rather unlikely... ecosystem engineering could easily cause more problems.

Re: Typical Musk

THe obvious meaning of the word "recall" is that the product is being "recalled". Which means "officially order to return to a place" and implies physical return.

Although it DOES make you scared enough to make sure you do something which is of course the main priority. Terminology could be improved because a minor software update should not need to be as harmful to reputation as something that requires a trip to the garage and losing your car for a time. If anything, it's wonderful that you CAN fix stuff like this over the air.

iPhone 14 iFixit teardown shows Apple's learning on repairs

JDX Gold badge

"Apple's still hoping you'll drop by the Genius Bar for repairs instead of going it alone"

Well who wouldn't want to sell their own services? What manufacturer doesn't tell you "you need to use official parts and authorised dealers?"

And for the vast majority, opening your own phone is probably not a great idea. I've experience inside PCs going back a few decades and I would still be wary. Apart from anything else, I value my own time.

If they've moved in the right direction then I don't really care if it's because they're being forced to, or to make their own lives easier doing repairs, or because "They Really Care". It's a good result. In fact, companies realising that repairability can be in their own interests is surely the best result as they'll then want to do it instead of being forced to.

Re: Not my Queen

"not my queen" shows rather a lot of ignorance ant entitlement. The queen or king is your queen or king, the PM is your PM, etc - no matter whether you voted for it or approve.

The modern view is that nobody has to accept any reality they didn't choose but this is unrealistic, self-centred nonsense. Trump was president for all those "not my president" people too.

The queen didn't choose (or expect) to be your queen either but she still was.

"the only person in England who never had to take a driving test" ?

I am fairly sure my late grandfather (he would be 105 or so) told me he just had to apply for a license. A bit of googling suggests nobody had to take a test prior to the mid 1930s. So many, many people never had to take a test... including many who drove.

A nice piece otherwise El Reg. The point that she was not raised expecting to become Queen is something I had never really thought about too much.

Scientists use dead spider as gripper for robot arm, label it a 'Necrobot'

JDX Gold badge

Re: What's the point?

They pointed out pretty clearly the benefits - basically 'growing' a robot appendage far more effective and far far cheaper than anything we can make.

As far as cruelty, how is this different than than thousands/millions of fruit flies which are farmed specifically to be used in tests? For that matter, we are being told that locusts or other creepy crawlies are a great alternative to meat and that means billions of the things will be grown and killed. Nobody is going to individually euthanize them.

If it were a million spiders being killed to extract some some of chemical, nobody would care. But show us a single spider on video and the fact we're reanimating its corpse we suddenly get up in arms (the spider doesn't care what we do with its corpse).

Many of us routinely kill spiders or wasps we see in our houses and we don't analyse the ethics. Somewhat hypocritical to lambast the scientists doing it for an actual purpose.

Re: Thanks NASA!

Isn't everyone in a good mood today.

I didn't realise the US government was "propping up religions". Or that data showed "all religions are failing". Numerically atheists are a minority, you may be speaking morally but in that case "it's obvious" is a statement that hardly ever holds true.

If you must be an angry atheist who can't help forcing their hobby-horse into unrelated discussions, at least be a moderately informed angry atheist so you don't give atheists a bad name. Better yet maybe we should just avoid politics and religion in the comments here. Neither ever leads to anyone feeling happier and calmer so why bother.

Do they deliberately say "oh this is only designed to last a couple of weeks" knowing full well it should have a much longer life? Is this so they never have things fail earlier than designed, or is it a scientific thing that "designed to last 2 weeks" means "designed to have a 99.99% chance it'll last two weeks?"

Re: Still missing?

Current scientific understanding hinges on about 80-90% of the universe being invisible and undetectable (for now, I can't remember if dark matter is one of the things JW hopes to understand?) Quite a large gap :)

But the 'god of the gaps' argument is and always been a bad one. Neither theologians nor physicists like it. You don't ascribe everything you can't understand "well that's God". Physics - as us physicists well be the first to tell you - is a study of what and how and when, not why. A complete unified theory of everything wouldn't remove that.
