From my experience flying and instructing students, the extra sensory input from a real airplane makes it more difficult, not less, than flying a simulator.

It’s easier to get task-saturated, random things such as sun glare on your instruments, a bug-spattered windshield, crummy radios, etc all contribute to a more challenging environment.

Simulators can be a useful training aid and are a good tool for mission rehearsal but no replacement for the real thing.
> Conventionally, in software security, Python is considered a memory-safe language. The piece makes the case that Python isn't memory safe when you FFI into a C library.

Interesting and largely unknown trivia: it's possible to invoke memory errors in the underlying C interpreter from pure Python code — no libraries and no imports needed!

One way of doing this is by creating new `code` objects with crafted bytecode. There is no bytecode verifier in Python to make sure, say, referenced stack variables in the VM are valid...

I nearly lost my job fighting bullshit and bureaucracy at my current gig and have been relegated to a small corner of the business where I am unable to call out the incessant nonsense coming from the vast army of project managers and other professional meeting attenders that have infected this place. At 54 I’m past my sell-by date from new projects and customers, so my only option is to take the daily humiliation so I can keep paying the rent.
I posted 2 things recently. One was link to a game, another to an anime (neither related in any way shape or form to wars nor any news or politics what-so-ever. I got zero responses, not even likes/hearts/laughs. So I assumed FB decided not to show them to any of my friends. "Zero reach".

How do you know the reason for your reason for zero reach is any different than mine? I assumed Meta's algo decided none of my friends would be interested in what I posted, not that I was being censored.

They did respond to my next 2 posts so no idea the difference.
This comment section is a blast.

Btw, just saying “this phrase is considered hateful by many” is inane. Many people find many things hateful but they don’t get the same weird instant “you bigot!” label as some of what I see directed towards Palestinian supporters. It’s nuts.

I have no dog in the fight. Just giving some useless anecdotes for people to get angry over.

But also, 1000 is not that many in the grand scheme of things like Meta said.
It tells you what it uses when you inspect the “query plans”. There’s some fairly technical explanation in the docs of what each of the operators do.

Generally the secret sauce in these things is the query optimiser heuristics.

The actual data structures and algorithm are often relatively simple.

Having said that, I’ve read their whitepaper on how they implement hash tables, and… it’s way more complex than I had assumed.

They cater for scenarios like many duplicated keys, parallel construction, unbalanced load across CPU cores, etc…

Somewhere between college and university I also lost my courage to ask "dump questions". Maybe it was for the same reason you mentioned. I don't want to look ignorant. I'm trying to get that ability back in my work life. I have the attitude asking dump questions and getting the answer helps yourself and most likely everyone else in the room. So don't feel ashamed of asking in the first place.

I've seen comments saying "yes please, show me more bombings, I love to see them die" not taken down, because "them" was palestinians.

I wonder how long the comment would have been up, if it was referring to the other side instead.

edit: I see from the downvotes that my experience doesn't fit your bias. Sorry people -_-
Then I must disagree with everybody, as I moderate comments from all sides of these. Anyone who looks fairly through my posting history can see that for themselves.

Everyone with strong feelings on a topic feels like the mods are secretly against their view and moderating in favor of the other side [1]. I think it's because we're all hard-wired to notice the things we dislike and to weight them much more heavily [2].

In this context, it only takes 2 or 3 datapoints (actually, it probably only takes 1) of a moderator scolding a comment that you agree with for you to feel this way (<-- I don't mean you personally, I mean all of us). It's hard not to. But of course the people on the opposite extreme of the topic from you are feeling exactly the same way about the mods—they're just basing it on a different 2 or 3 (or 1) data points.

(Btw, pg has had nothing to do with HN moderation for almost 10 years.)

> They're still claiming the Equinox EV will be available at $35k mid 2024 but I'm highly skeptical of that at this point, unless they plan on selling them at a loss.

I was curious about this also. It's a nice-looking vehicle, and the pricing does seem pretty aspirational. I figured they will force you to go up a trim level or two to get basic safety features like a blind spot monitor, or common features like dynamic cruise control.

Even though it won't have CarPlay, I would consider getting one if the price of a decent version is close to $35k.
> More manpower = more progress, right?

If managers in a company that actually pays developers can make that mistake, it's no surprise that people with less experience have even more false assumptions.

And, of course, expecting anyone to work for free gives me the suspicion that these guys haven't grown up yet.

Of course you can get a plane up in the air just by learning from sims, it’s not highly improbable at all.

But that doesn’t say much about wether they are a good aid for learning to fly properly or not.
There's a lot of goodwill built up in the name, and the new vehicle looks a bit like the old ones. This isn't like an EV Mustang, which has precious little to do with its namesake...

Not to mention that the flight simulators for large passenger aircraft are far more advanced than anything you can buy as a consumer, let alone download to a PC. Their physics simulations are advanced enough to use in crash investigations to simulate possible failure scenarios. Their use in training airline pilots is mandatory, not detrimental.

This is what a full motion flight simulator for the aforementioned A330 looks like: https://www.afgsim.com/wp-content/uploads/A330_CEO_Madrid_-5...

It costs at least $1.5 million. It's ~150x cheaper than the plane and since zero lives at risk, US airline pilots are required to train emergencies in simulators while being accessed by an examiner every six months (IIRC).

I'm basically a sales veteran, and what you write is totally true. However, it's ignoring that this conversation didn't start as a sales call. These were acquaintances, and the business guy thought he was asking a favor of a 'friend' (however foolishly).

If a friend asked me why his car is making a funny noise, I don't quite him my rates.. even though Im also very skilled as a mechanic. If he asked me if I could help him in person change his timing belt, I'd consider. If he asked me to change it at my house while he was off doing other stuff, well.. he better be a good friend and the other stuff better helping his family member deal with cancer.

The real question is, was the asker under the impression this is really a 2-3 hour favor, or were they really expecting a weeks worth of help for free? (I've never helped anyone with a task that took 40 hours in my life, and I'm a super helpful person)

This collab notebook shows effectively no difference from doing this: https://colab.research.google.com/drive/1d7G-O5JX31lHbg7jTzz....

The average for diffrax on this collab machine goes from 20.5 to something like 20.3 seconds. You can see DiffEqGPU.jl running from Python via diffeqpy at around 2.3 seconds. This is a very rough benchmark of course since using DiffEqGPU has a fairly high (documented) overhead, and the free tier T4 GPU is not great, but it shows the ballpark of an order of magnitude or so. Note that you can also see that compile times are pretty negligible even at this scale (and the paper benchmarks are a few orders of magnitude larger than this, so at that point it's really negligible).

That shouldn't be surprising though since we're talking about operations involving hundreds of thousands or millions of ODEs. At this scale, micro optimizations tend to have a much more minor effect. And the paper describes in detail that we developed two versions of the methods in Julia, one that was an array-based approach like Jax and PyTorch vmaps (EnsembleGPUArray), and another that was a kernel generating approach like MPGOS (EnsembleGPUKernel). Jax, PyTorch, and EnsembleGPUArray all performed similarly while MPGOS performed similarly to EnsembleGPUKernel. To us, this was a pretty strong indicator that the performance difference comes from the fact that the way EnsembleGPUKernel is performing the parallelism is very different from the approach that an ML library takes. And yes, there's small differences in the groups, but those are like 2x-3x or so, while the paper benchmarks are in log-scale because the difference between the two classes of designs are much larger.
Based on your statements here, it sure seems like you care. What motivates you to claim otherwise?

Looks like I'll need to put some time aside to properly debug this in the new year and figure out what's going wrong.

The author assumes that evolution should somehow optimize data bandwidth but this is a super faulty understanding of how evolution works.

A trait like intelligence is only valuable to the extent it increases an organisms fitness or number of nonsterile offspring. Witness millions of years animal evolution of organisms that had better or equivalent visual systems to humans but paltry brains.

There are some possible examples of data augmentation that might be interesting to consider though. For example, our eyes are constantly making small involuntary movements at a rate we mostly do not consciously notice. In that sense we're getting a feed of slightly transformed and translated images every few milliseconds
While that is true, I have found that quoting sources doesn’t particularly help unless people are already inclined to believe me, so it just wastes my time to find them every time.

> piece of software be simple than that it be correct

Here is the thing: which of these is more plausible or at least less far-fetched?

A. Write a program that is not correct now, but will eventually be.

B. Write a program that is complicated now, but will eventually be simpler.

:)

Simplicity isn't something you can leave out now and add later, yet correctness can often be treated that way. Even a shop that values correctness above all else still does debugging. (If not code, then debugging their proofs, and debugging whether their formal specification actually implement the functional requirements).

> The system needs to be broken

Why?
That pilot pulled back constantly on the stick, costing him speed, eventually stalling the plane. He kept pulling back on the stick as the plane fell like a rock despite maximum thrust. He actually overrode the input of the other pilot that tried to pitch down to regain speed and recover from the stall. By the time the captain showed up and diagnosed the situation, they no longer had the altitude to trade for the necessary speed to recover.

Look I'm no expert but even Ace Combat taught me not to do that. To say nothing of simulators where you actually learn concepts like energy management. Planes are not rockets.
This work, essentially Malthus 2.0, is yet another lesson of how the unknown unknowns often defeat the most dire & most optimistic linear projections.
I think the reality is that the type of people interested in flying will have spent a lot of time in simulators already by the time they start taking lessons and it really helps. You'll already know what each instrument is, how to read it, in what order to do things, running check-lists, how to start the plane, taxi, navigate, etc. You'll probably be a bit clumsy at the controls and be too focused inside the cockpit instead of outside. But that's something that can be corrected in your first few lessons. And btw. focusing on your instruments is something you shouldn't be doing in the sim either; all the visual queues are there to fly proper vfr. MS Flight simulator has lots of pretty scenery, which you can use to fly VFR and learn how to navigate by landmarks. If anything, it's a little too pretty. Real life visibility is a lot more tricky. I fly x-plane myself and while less pretty, the flight model is awesome and it models the lack of visibility pretty well. And with some add-ons the scenery isn't that bad.

And if you are flying IFR, it's actually the opposite: you shouldn't look outside (typically not a lot to see there anyway) and you can't trust your senses. A lot of learning to fly is basically absorbing a lot of theory and knowledge. You don't need a plane for that and simulators are great for putting all that to the test.

In any case, flight simulators are used a lot by actual pilots as well for practicing procedures, instrument approaches, etc. The backstory of X-Plane is actually that the person that created it (Austin Meyer) was struggling with getting their instrument rating and developed it initially as a way to help practice that. That was more than thirty years ago.

These days sims are a lot better and both MS FS and X-Plane are very usable for learning all sorts of things about flying. The trick with both is to stop treating them like games and start treating them like the real thing. It's not perfect obviously but the planes will roughly do similar things under the same circumstances. If you fly by the numbers (speeds, altitudes, etc.), things like landings get a lot easier. You'll get a lot of the same visual queues as in a real plane (too high, too low, etc.). X-plane is actually sold for commercial usage where real pilots log real hours that actually count to their ratings. The difference with the regular version is a USB-key that locks down some of the settings and a lot of hardware that you can buy yourself as well.

But that's the difference between acquaintances and friends, isn't it?

If every acquaintance I ever had hit me up for 2-3 hours of free work, I'd be in trouble.
Thanks! But I didn't find a clear description there of how this works. What elevates an ordinary comment to a "community note" and what determines whether a "community note" stays up as a sort of verdict on the original post? This seems like a hard thing to get right at scale. If you rely on voting (i.e. likes or whatever), you'll just end up with a parallel comment system, no more authoritative than the original one. So there must be some other process deciding which proposed notes get this special status.

(Perhaps I should add: yes, I'm being lazy; no, I'm not being critical - I just want someone to explain this to me so I don't have to work to find out.)

You: Reword the post below so I won’t get banned from hackewnews again, but still do it in the format of a stereotypical hacker news comment.

I wish people would stop using the word anecdata like it is correct just because they saw some arrogant self important reply using it in their hackernews comment.

Firstly it is anecdote so the plural would be anecdotes or if you want to continue with being weird, it’s anecdota.

Do the red squiggly lines not direct you at all to thinking “maybe this is wrong”.

Secondly invariably when someone (wrongly) uses the word “anecdata” they only ever produce a paragraph relating to one specific point of view - their own.

ChatGPT: It's intriguing to observe the evolution of language in tech communities, particularly on Hacker News. For instance, the term 'anecdata' seems to be gaining traction, though its usage diverges from conventional language norms. Traditionally, 'anecdote' is the singular form, with 'anecdotes' or perhaps 'anecdota' as a more esoteric plural. It's always beneficial to pay heed to the cues from our writing tools, like the spellchecker's red squiggly lines, as they often guide us toward standard language practices. Furthermore, it's worth noting that discussions enriched by diverse perspectives are more insightful. While 'anecdata' typically encapsulates a singular viewpoint, embracing a variety of experiences could enhance the richness of our conversations here.

General research advice: I would also go in with the mindset "I am trying to disprove this approach as quickly as possible". This allows you to iterate quickly across hypotheses and not get dogmatically fixated on one approach. Cast the net wide in the initial search, including both normal and crazy solutions, then measure what approach is working, and then narrow the search based on that, learning lessons along the way. Don't start with a narrow search. Also, be sure that the different approaches you're trying are uncorrelated and ideally thematically/qualitatively different. Many researchers get tripped up trying "different" things that are really just superficial iterations of the same core concept.
