I work with a lot of Chinese. I can confirm that they like to work in 1st gear a lot, rebuilding the same stuff over and over in reaction to changing requirements. Because of their immense capacity for work, it more than compensates for what westerners might desire in long term planning. I have gained quite a bit of respect for this way of work due to the results they have gotten.

Equities and "delta 1 assets" are very liquid, meaning there are a lot of buyers and sellers. This helps to make price discover more efficient. Anything outside of that means that there is much less liquidity and therefore inefficiencies in price.

Think about it this way. You are trying to sell an apple. In one room, there are 100 people trying to sell an apples and 100 people trying to buy them. In the other room there is 1 person trying to buy apples and no one selling. In the first room you don't have much leverage. The buyers can go to the other 99 sellers if they don't like your price. In the second room you have a ton of leverage. If the person wants to buy an apple they are either going to have to buy it from you or wait for another seller to enter the room.

When it comes to non equity or delta 1 assets, there tends to be more complexity in understanding the assets, which acts as a barrier to entry. If you have been in investment banking for 6+ years, you likely understand these complexities and can find pricing inefficiencies.

You write a tech debt ticket and move on.

I've used a similar mantra of "make it work, make it pretty, make it fast" for two decades.

I think I've had to get to step 3 once and that was because the specs went from "one device" to "20 devices and two factories" after step 1 :D

Anecdotally I've had a lot of problems with Anker products over the years. On two separate occasions my power banks died while I was travelling. I had a few Ravpower products that were at least as good. And now Ugreen seems to be producing good stuff.

I don't think there is any stickiness here, and it's a cutthroat market. These things are all at a price point where there will never be a winner-takes-all.

I had been planning to explore Lima tonight as a mechanism to shackle CC on macOS.

The trouble with sandbox-exec is that it’s control over network access is not fine grain enough, and I found its file system controls insufficient.

Also, I recently had some bad experiences which lead me to believe the tool MUST be run with strict CPU and memory resource limits, which is tricky on macOS.

When you are cooking you should be using a lid. So you bring the water to the boil at full heat and then turn your stove down to keep the water surface just shivering. With the lid on this will be more than hot enough. People talk about “a furious boil” and a “gentle boil” but if the water is boiling it’s boiling.

The video link that's posted on the article is all over the place. IMO, it's hard to state what her conclusion was since it's not concrete at all. In the first half, similar to the post itself, the video argues that since there is H1B approvals for these companies which laid off workers, that means that citizens are being replaced by immigrants. In the second half it states that warehouse workers and other unskilled jobs are getting replaced by AI. And it (with a bit of snark) asks why if AI is so good , they still need to hire H1B workers.

But that is exactly the point. H1B workers aren't workhouse workers. They are doing tech work. Saying companies are doing lay off and hiring H1Bs doesn't in any way establishes what kind of workers are getting laid off and what kind of workers are getting hired.

As others have pointed it out, the data presented is so insufficient to such a degree that in this particular case, I have to wonder if this is genuine curiosity of the author of the post or if they are trying to justify their beliefs using bad data science.

War planes dropped natural stability a while ago, IIRC the F16 was the first relaxed stability production aircraft (it's naturally stable at supersonic speeds but not subsonic).

In fact there was a flying airliner with relaxed stability (though only neutral not negative) when Airframe was published: the MD-11. Though I don't know that there have been others since.

LOL... I love how anal engineering types (like myself) can be at times.. going down rabbit holes like this and definitely appreciate it. Pasta is a hard thing and I tend to not rely on timers at all beyond around 8m... I just start testing a piece every 30-40s or so until I'm happy.

This will also vary by final application, if I'm going to rinse/cool to stop cooking, etc... if it's going into a bake after being made (mac and cheese, casserole/hot-dish, etc). It will just depend on a lot of factors beyond how done it is in the pot.

Edit: also, altitude, pureness, salinity, etc of the water will also change things dramatically.

I think you might have the chain of causality mixed up. From what I've seen, the sheer scale of the company creates large committees because you've got lots of managers and they all know that getting involved in the project is essential to their career advancement. And then that creates scope creep. Partially due to design by committee effects, but also because the manager in charge of flobnix realizes their opportunity for career advancement by shoehorning problems that need to be solved with flobnix into the requirements.

I also suspect that, if the folks leading this effort at Boeing are smart, they will sit back and let it happen. Large bureaucratic organizations like Boeing are ruled by office politics and largely run by people whose individual priorities are not particularly well-aligned with large scale company priorities. Pushing back risks making enemies (a dangerous thing to have in such an environment) and tends to have no real immediate upside.

Concrete example: why is the Lunar Gateway such an essential part of the Artemis project's mission architecture when we didn't need anything like that for Apollo? Many reasons have been given, but I suspect the real one is that 2020s NASA has a lot of people who specialize in space stations on staff and 1960s NASA didn't.

You said this like it is a bad thing, which is baffling? Obviously cars should do this. One of the best things about adding self-driving features is we can add features like this (and speed governors) to make cars a lot safer for everyone.

> I don't know whether consumers/buyers are demanding that, or what.

Consumers aren't demanding it, investors are.

They see the hype and ridiculous amounts of money being invested into AI startups, and they're afraid of missing out, so they throw their own money in. No time to stop and think about it, there's too much hype and things are moving too fast. Then other investors see even more money being thrown in, and throw more money in themselves - monkey see, monkey do. Repeat ad infinitum and the next thing you know, majority of venture capital is being blindly funneled into anything AI related.

If you're leading some unrelated company and paying attention to where all this money is flowing, the path forward is obvious: simply become an AI company. Doesn't matter if you're actually building something valuable with it or not, because as long as your landing page fulfills a certain quota of AI buzzwords, the investors won't care. They only care about making the line go up, because it's good when the line goes up.

It's a bubble.

> If you want passengers to want your plane, design it without sardines in mind; People don't like being sardines.

Isn't that something that's more the responsibility of the airlines, who decide how many seats are put in a plane, following the limits of the aircraft? Like if you want more legroom you take a more expensive ticket from a company that doesn't try to cram as many passengers in each plane

No, it does not, hence the name. It is a reaction to the way Wikipedia has been taken over, not an honest effort to create a true encyclopedia.

A better solution would be to create a Wikiproxy which adds the missing viewpoints to Wikipedia articles without throwing out the baby with the bathwater. This will be impossible for some articles which are too heavily slanted but even there such articles can be included as an addendum to real NPOV articles. Such a proxy should do away with the 'Perennial Sources' scam which is used by Wikipedia to keep out dissenting voices, relying on editors to weed out nonsense.

Now that I think of it there might be a way to get something off the ground fairly quickly by creating a 'meta-encyclopedia engine' which pulls in articles from several user-definable sources, e.g. Wikipedia, Britannica, Everything2 and whatever other sources [1] and allows editors to comment on subjects by referring to content from upstream articles as well as by adding their own content.

While not great, the MAX would have been fine if Boeing (and their airlines) had not clung so hard to the type rating. Without that, MCAS could have been left out entirely alongside its utterly botched implementation.

But that would have required a heavier certification process, and some pilot re-training. And they couldn't have that.

Of course that wouldn't have freed Boeing from the rest of its dismal record (MCAS didn't cause door blowouts), but...

At a dinner with a team of Airbus folks we were working with at a previous job, they talked about how difficult it was getting to source CPUs for the A320 after 30 years.

It's definitely a "if it ain't broke don't fix it" thing, but I ask myself a similar question: at some point whoever is producing these chips is going to stop finding it worthwhile and end production, no?

But then I also assume the people who work on these things know arguably infinitely more than I do.

>Next, consider the time needed for Achilles to reach the yellow dot; once again, by the time he gets there, the turtle will have moved forward a tiny bit. This process can be continued indefinitely; the gap keeps getting smaller but never goes to zero, so we must conclude that Achilles can’t possibly win the race.

Am i daft, eventually (Very soon) Achilles would over take the turtles position regardless of how far it moved... I am missing something?

I haven't seen comments regarding a big factor here:

It seems like OpenAI is trying to turn Sora into a social network - TikTok but AI.

The webapp is heavily geared towards consumption, with a feed as the entry point.

The editing aspect seems very secondary.

Generated videos are very short, with minimal controls. The only selectable option is picking between landscape and portrait mode.

There is no mention or attempt to move towards long form videos, storylines, advanced editing/controls/etc, like other products in this space.

Seems pretty clear they want to turn this into AITok.

The world falls into two categories for me. "Must be fast" and "I don't care (much)". C/C++ is ideal for the first one, and C# is awesome for the second.

My argument isn't that C# is bad or performance is unachievable. It's that the mental overhead to write something that has consistent, high performance in C/C++ is very low. In other words, for the amount of mental effort, knowledge, and iteration it takes to write something fast + maintainable in C#, would I be better served by just writing it in C/C++?

The linked assembly is almost certainly non-optimal; compare to -O3 of the C version: https://godbolt.org/z/f5qKhrq1G - I automatically get SIMD usage and many other optimizations.

You can certainly make the argument that if X, Y, Z is done, your thing would be fast/faster. But that's exactly my argument. I don't want to do X, Y, Z to get good results if I don't have to (`return ref Unsafe.Add(ref MemoryMarshal.GetArrayDataReference(array), (nuint)index);` and using/not using `[MethodImpl(MethodImplOptions.AggressiveOptimization)]` are non-trivial mental overhead!).

I want to write `foo.bar` and get good, alloc free, optimized results... and more importantly, results that behave the same everywhere I deploy them, not dependent on language version, JIT specifics, etc.

If I was operating in a domain where I could not ever take the C/C++ path, these features of C# are of course very welcome. And in general more power/expressiveness is very good. But circling back, I wonder if my energy is better spent doing a C version than contorting C# to do what I want.

I also used it for software engineering and personal use as well.

I had two major issues with it:

- it wasn't as snappy as google, but I kind of got used to it

- I wasn't trusting it (if that makes sense) and was falling back !g to make sure everything was searched

For $10, I expect to get a premium service, not a just good enough one.

I have to admit that I liked the idea, feeling of privacy and the ability to tailor a search engine for my needs.

Unfortunatelly I think that they are not where they need to be for the $10 pricing plan.

That's by design. Wouldn't want two of these to stomp on each other. It would be an interesting question to build something that can support some concurrency, for instance most of these times two projects are going to install different files and the only conflict might be in managing the actual package database.

It would be like the time they took the giant lock out of the kernel, but that kind of thing is fraught. I remember a few years in the 2 series where we were getting crashes all the times under heavy load from concurrency bugs after they took out that lock.

No idea! But I found this part of the paper confusing: "between the conception of Aert van Beethoven’s son Hendrik in Kampenhout, Belgium, in c.1572, and the conception of Ludwig van Beethoven seven generations later in 1770, in Bonn, Germany". I think that means that there were 8 generations from Aert to the famous composer, so Aert was the great...grandfather with 6 greats. (How many people know their family history that far back?)

The Wikipedia article for the composer's grandfather (who was also called Ludwig) says: in 1712 two boys named Ludwig van Beethoven were born. The two families were distantly related. [...] it is not certain "which Ludwig" actually settled in Bonn in 1733

But presumably both of those boys were officially descended from Aert so it doesn't matter for the purposes of this analysis.

Occasionally I make an analogy to stage acting or opera. In order for the people in the medium priced seats to see the action on the stage, all the actors have to over-emote to make everything that is happening dreadfully obvious.

In a system that is the composition of 30-300 different functional units, nobody will be close to any one part unless they’re the bus number for it. So each piece needs to be dead obvious so you can worry about the consequences of composing them. At the end of the day it’s Kernighan’s Law but rephrased so as not to ignore Conway or Brooks.

> Given that outcome, I (from the peanuts gallery) would design the aircraft to handle in some ideal way using MCAS-like automation to fix any deviation from that ideal, from the beginning. Of course, that's starting to head down the road of a more-Airbus-like design.

The 787 and 777 are already purely fly by wire. Their entire feel is made up.

Boeing simply has a different design philosophy on how much a pilot should feel like they are in command vs steering a system.

> I will say, their pricing and deployment strategy is a bit murky and unclear. Paying $1500-$10,000 per month plus usage costs? I'm assuming that it has to do with chasing and optimizing for higher value contracts and deeper-pocketed customers, hence the minimum monthly spend that they require.

Yeah wait, why rent chips instead of sell them? Why wouldn't customers want to invest money in competition for cheaper inference hardware? It's not like Nvidia has a blacklist of companies that have bought chips from competitors, or anything. Now that would be crazy! That sure would make this market tough to compete in, wouldn't it. I'm so glad Nvidia is definitely not pressuring companies to not buy from competitors or anything.

> That can work-- we should engage in creative destruction, the administrative state did restrict economic growth, and it did create carve-outs out of the Constitution.

The highest level of economic growth (GDP), and total factor productivity growth, was between 1929 and 1973. It was also the time period when income inequality plummeted (post Gilded Age).

All three metrics have gone down hill since 1980 and the mainstreaming of neo-con economic thinking.

I find it highly depends on the maker of the pasta, and the variety in use. 9 minutes followed by immediately serving is actually quite conservative for some brands. It also depends on the cooking method and how long you intend to finish them in the sauce (or just cook them in the sauce - heresy, I know, but it fucking works).

It's not that obvious. iOS is pretty secure, if they keep the social network and cameo feature limited to that there might not be good ways to export videos off the platform onto others beyond pointing a camera at the tablet screen. And beyond there being lots of ways to watermark stuff to be detectable, nothing stops the device using its own camera to try and spot if it's being recorded. The bar can be raised quite high as long as you're willing to exclude any device that isn't an iPhone/iPad.

Sure, I'll give some numbers.

Sharpe ratio = (Your return annually - Annual Risk Free rate) / ( Annualized Vol of your portfolio).

BB = Bulge Bracket, basically a Tier 1 Bank (Goldman, UBS, MS, Citi, google the list).

Equities = Stocks.

Delta 1 = If underlying moves by X $, your product/ derivative moves by X $. Basically swaps, etfs, futures, etc.

Now for some numbers: Say you are under a "vanilla" 2/20 structure (which is actually like 10 years out of date but is still listed on all finance websites) where your fund charges a 2% management fee (i.e if you manage 5 mio USD you charge 100k per year for fund cost) and 20% performance rate on your gross above benchmark ( so you take 20% of the return above your benchmark).

Annualized SP500 vol is let's say 18%, your cash return right now is 3.5%. Quick maths gets you to 4 Sharpe is about 75% yearly return. ((75-3.5)/18 is about 4).Under these assumptions, 4 Sharpe return on 5 mio is 3.750mio.

Your performance fee as a HF manager is gonna be 0.715(75%-3.5%) x 0.2 x 5mio = 715k. So 4 Sharpe on 5mio is basically you earning 900k-1mio USD (depends on the jurisdiction for your base, i took like 180k USD for base) as the HF manager.

Edit: For people who don't trade professionally, capacity (i.e how much money your strategy/you as a trader accept before becoming inefficient/losing money) is the big filter. There's a shitload of strats that work at 1 mio USD but completely stop at 2mio or 5mio.

Very good points. About ARM1, 2 and 3, if my memory from 4 decades ago is correct then the changes from 1 to 2 were a move to a slightly newer process node, replacement of "multiply step" with actual multiply instructions and the addition of the co-processor interface. 2 and 3 are the same processor, but with the latter adding a 4KB onboard unified cache, which allowed it to run at a much higher clock frequency.

I can't find the link now, but I saw a continuous shot video of a grocery store from the perspective of a fly. It was shot in the 90s music video style and looked so damn good.

Some of the stuff being done by these guys is also a whole lot of fun (slightly NSFW and political content), and it fits the music video theme:

China recently started building and delivering airplanes. It will be interesting to see if Boeing can actually compete with what is coming out of China over the next few years: https://www.voanews.com/a/7528331.html

In the short-term, I imagine USA-based airlines will not be allowed to buy any airplanes from China: https://www.reuters.com/article/us-usa-china-comac-military-... And perhaps they would not even be allowed to fly in our airspace. But if China decides that it wants to build planes at lower prices than Boeing (or Airbus), then I imagine they will. Their marketshare would grow elsewhere in the globe, reducing Boeing's sales. Can Boeing deal with that? Would the USA borrow China's playbook, and nationalize (or something similar) Boeing to keep it solvent?

> They gave the wing design away to Mitsubishi for fucks sake. You never do that. They were neck deep in the McDonnell Douglas metastasis at the time

The 787 was a straight up MDD pants-on-head plan (pushed by Stonecipher and McDonnel themselves), the entire point was to shift the costs of design and development to suppliers, with the idea that they'd fund the aircraft you could sell.

I think duolingo is taking some steps. Not sure how effective they will be.

they have added some "write your own sentence" exercises in recent months. generally a story you listen to and then you write a summary or answer a question about why or how something happened in your own words. your sentence is then graded/corrected by AI. these are still rare but they do make me think more than the typical forms.

there is also some new more expensive level called Max that claims to have audio conversations with you using AI. I haven't tried that one.

>If you want passengers to want your plane, design it without sardines in mind; People don't like being sardines.

The manufacturers don't actually have a ton of say over this. At the end of the day, it's the airlines who decide how many seats in what configuration the aircraft will use - not the manufacturer of the plane.

And airlines only pack so tightly because competition is fierce and flyers almost exclusively only purchase based on price.
