> The compression effect of the jet engine blades is what ignites the fuel

Not exactly, the igniter ignites the fuel initially, and after a short while the combustion becomes self-sustaining (i.e. new fuel is evaporated and heated above its autoignition temperature by all the residual heat around it). The igniters are turned off after a while and are only turned on again under certain conditions (high risk of flameout for a variety of reasons).

Also the "hot gasses from the fuel burn produce thrust" part has slowly become more and more incorrect, because nowadays in airliners we use what's called high-bypass turbofans where the primary purpose of the hot engine core is not to generate thrust, but to drive a turbine connected to the huge fan in the front, which sends most of the air AROUND the core ("high-bypass") in order to create thrust. The core does produce some thrust, but the air coming out of it is pretty fast and creates more noise, so we try not to have too much of that.

And the core itself doesn't really need to burn fuel, you could rip the combustion chamber out and put a nuclear-reactor-fed heat exchanger there and it would work the same.

Or a beefy electric motor that would drive the fan and also utilize its waste heat to imitate a very-high-bypass turbofan.
And then you get to the unfortunate situation that is the x64 ABIs - int is still 32-bit, leading to a bunch of extra movsx instructions if you use ints for things like indexing.
> while having clear understanding that it is not sustainable

That hasn't been demonstrated. It could be that when the decision was made to offer free/unlimited storage, there were beliefs about the economics of that option -- particularly, the rate of change in durable storage pricing and performance -- that ended up not being borne out. (I am not privy to any special knowledge about this, but it is at least plausible based on how the storage business had been working for the years leading up to 2015.)

I agree in general that teaser rates -- as opposed to well documented free tiers -- are at best a gray area.

It’s not really practical to sue a thousand small businesses — you might not even hear about them. And anyway it’s better to go after a product with a protected high margin than try to fight where somebody else can attack your margin.

BTW it wasn’t “the chemist and his friend” — that would have been a crime. It was a few chemists in the company dosing themselves — also technically illegal but done all the time and generally excused if it’s a trivial scale and disclosed in your filings.

Hmm not sure if troll, but energy conservation is definitely not just some convention. It’s a fundamental thermodynamic law. Spooky action at a distance does not violate speed of light information propagation either. The particles have to be entangled before they’re set off in opposite directions. Only once one is observed does the other also collapse, but it doesn’t mean you can communicate faster than the speed of light because you had to prepare the information when the particles were together IIRC, it’s been a decade since I studied quantum information theory.

No, this is a myth. In reality, lead fouling decreases engine performance and longevity. From https://www.shell.com/business-customers/aviation/aeroshell/...:

"The temperature for Lead deposits to form tend to be favourable around the spark plugs (as the whole mixture is quite cool before the flame starts to propagate) and on the exhaust valve stem (as the mixture cools after combustion). The problem is that the deposits are electrically conductive, which shorts out the spark plug - and corrosive, which can start to attack the metal of the valve stems."
The distance doesn't dilate; time does. The distance contracts.

E.g., to a photon moving at 1c, the whole universe has a contracted length of 0 meters, and it crosses the whole universe instantly. To us, observers at <1c, the whole universe has a non-contracted length of <a lot> and the photon takes <a long time> to cross the whole universe. By the time the photon's 0-second journey across the entire universe has finished (whatever that means), we're all extremely old. :D This is the time dilation meme of slowly-aging space travelers but taken to the extreme.

It was using urea to fight topical fungal infections (anti fungal drugs are typically quite toxic). The mechanism of action has been well known for decades; what the folks came us with was a formulation that got the dosage high enough without causing damage. It was easily whipped up in the lab but I don’t remember the details. Any notes from this would be long gone as this was over a decade ago and the company has been sold and surely any paper lab notebooks are buried and forgotten.

Late addendum, just in case anybody reads this:

Kernighan wrote that paper after writing "Software Tools In Pascal", and finding it considerably harder than it should have been to write that kind of thing in Pascal. (The predecessor book, "Software Tools", was written in RATFOR, and Pascal should have been miles better to write software in.)

In this book, they (Kernighan and Plaugher) tried to write code that would work in Pascal, not just in one dialect of it. That is, portability was essential to the code they were writing for the book. That may have lead to a greater emphasis on portability in Kernighan's paper than one might think warranted by the general situation.

My whole house is a 100amp hookup. Its unreal to think what the costs for new lines being ran from the pole to house could add upto.

Aside from that, its a rental property with no garage. And since I have sat by for the last two years with the dream of owning a house becoming more of a pipe dream by the week. I find the discussion of morality and ethics of this repugnant.

As I understand it, much of the costs of soaring homeprices (in all respects) are due to mostly erroneous changes to building codes, zoning laws, municipal differences, and so much other red tape.

Overall, I still see these properties being put up overnight if you will, and am left wondering (specifically in the US) how much care or cost was put into extending the life of properties by building them well. I know Europe has a much better understanding of the benefits this has overall. I wish it were true in the states.
> I don't think you realise how simple and fundamental the CAP theorem is

May I recommend reading "A Critique of the CAP Theorum - Martin Kleppmann", available as a PDF here https://arxiv.org/abs/1509.05393

As that paper points out, your definition of CAP theorem is simplified and incomplete to the point of being wrong, as many are.

As it also point out, CAP theorem doesn't really account for eventual consistency well.

I would argue that a chat protocol is a good place to perform eventual consistency, and those tradeoffs work well. During network partitions, have both sides of the partition continue to accept messages. Have the client mark messages with random unique IDs, and have each server mark messages with a server timestamp. The well-defined merge operation is now to sort by server-time and dedupe by message ID, such that if a message is sent to two servers it only displays once.

This doesn't work for IRC traditionally, since messages do not have unique IDs, and so no merge operation can deduplicate them, and servers do not store messages during netsplits (or at any time really), so they cannot be re-sent.

However, a similar system exists for other chat systems. matrix is a federated system of multiple servers, and when partitions occur, each server will still accept new messages, and later those messages will be made available to other servers and merged in at the appropriate time.

I think that CAP theorem's results are less interesting if you consider application-level resolutions to network issues (i.e. eventual consistency), and as I believe the paper also implies trotting it out constantly when talking about practical systems gets old fast.

OpenAI's rules on chatbots are pretty straightforward, and pretty limited - it sounds like they basically don't want anything that isn't scoped to a specific goal, like reading a customer service script.

https://beta.openai.com/docs/use-case-guidelines/chatbots

Based on that, I'd imagine that what happened here basically boils down to OpenAI telling Rohrer his bot needs to be drastically different to meet those rules, and him (probably correctly) deciding that the result wouldn't be worth working on.
Biden's vaccine mandate on large private employers is really an attempt to mandate that individuals be vaccinated. Otherwise the mandate might apply only to workplaces where many workers gather, not to large companies where people are currently working from home. Even many Republicans who think the vaccines are effective do not believe the Federal government has the authority to mandate that individuals be vaccinated. A sample of their reasoning is here: https://nypost.com/2021/09/10/biden-knows-his-vax-mandates-a... .
Exactly, the idea that AI techniques are risky is a minority viewpoint. There is a community of smart people who are very interested in thinking about and mitigating the risk, but it's not something that most ML researchers think much about at all.

Most researchers in ML are just interested in pushing the field forwards. The "risks" in improving ML seem equivalent to the risk that Intel will make a processor so powerful that it takes over the world. Researchers are also aware that given the current capabilities of AI techniques (and current AI techniques are not that capable), it's just as likely that the next JavaScript framework drafts the world economy into making paperclips exclusively.

The idea that AI development is risky has a few hardcore supporters and is widely popularized, but most people working on it do not feel that it's a problem worth worrying about.
I would guess one thing that confuses non-pilots is that while say an A320 or a 747 looks like it has jet engines, lots of small regional aircraft (e.g. a Dash-8) visibly have propellers, and so it's natural for lay people to assume that's basically the same idea as on a Cessna 172 or a Spitfire scaled up.

But it isn't. Those planes aren't aren't fuelled by AvGas. Their engines use JetA (basically kerosene) because they've got a turbine inside like those turbofan engines which look so visibly different, however their turbine powers the propeller rather than a set of fans to drive more air through the engine and produce thrust that way.

Wow thank you ! I have read the whole article but I couldn't wrap my head around it. I found the "rod story" confusing then I followed your link (and also watched the related Youtube video)..

We Now Know Why There Are Dead Galaxies Floating Lost in the Void of Space
The best analogy for this I've read is that your motion through spacetime is constant. Think of a quarter circle dial with an arrow that goes all the way from 0 degrees (no relative movement in space) to 90 degrees (relative speed of light). The faster you go through space, the slower you go through time. The effects of this are barely noticeable until you get near the speed of light. This effect is time dilation.

This, I believe, is the general relativity view of spacetime.

What I like most about this is that it highlights the importance of understanding the domain of a function. The above shows how any object with rest mass has a space velocity domain of [0, c).

People really don't want this to be true so latch on to any wild theory that would seem to bypass this cosmic speed limit, be it wormholes, FTL drives or whatever. Pretty much all of these theories rely on taking an equation with a domain over real numbers and plugging in negative values for things like mass.

Garbage in, garbage out.

I mean if mass can be negative, why limit yourself to real numbers? Why not a complex number for mass?

As to why this is the case and how to reconcile it with a quantized view of spacetime... is beyond my pay grade.
> What nastiness are we subjecting ourselves to today?

Maybe an overwrought comparison but I genuinely do feel like we’ll look back on this age of social media and disinformation in the same way we did leaded gas. The people making money knew exactly how dangerous it was and the problems it caused but they did everything in their power to cover it up in the name of profit. Originally it felt like a social annoyance and not much else but in this era of vaccine denialism, election fraud conspiracy theories, even body image issues from touched up photos, there’s little doubt in my mind that society is suffering and that the problem will likely get worse before it gets better.

And what if I left earth at 50percent of light speed , traveled 1 light-year away and did a turn and came back to earth at same speed. For me, it would be 1 year, but if I had a twin brother who was waiting on earth, would i now be a year younger than him? And how is this possible?

It's pretty widely accepted by now that the premise for Iraq 2.0 was manufactured by the GWB administration.

Regarding 9/11:

I think Cheney was pulling the shots and knowingly and cynically ignored all of those glaring warnings, thinking they'd get maybe a small attack somewhere with a smaller number of US deaths, which would sort of be the cost of doing business in the middle east, and that this could be politically expedient in the context of his larger vision on how to deal with "the Iraq/Saddam problem", and in the larger picture morally "fine".

Btw: Dick Cheney is actually still around. How he and GWB never were indicted is beyond me. Don't get me started on the GWB PR rehabilitation campaign that has been ongoing during the the past ~6 years.
