You can run double-blind studies on yourself, if you are curious.

Gwern is famous for running lots of self-blinded experiments on himself.

There's various ways to go about this. But basically, you need to find a way to get two different pills that look and taste the same, one containing your active ingredient and one containing a placebo. Eg you quickly crush your vitamin pill (and the placebo) and fill the result in a capsule each. Put each in an empty film canister (or so) and label the bottom.

Shuffle both canisters (not looking at the bottom), and pick one at random. Consume the pill, and note down the effects over time. Keep the two canisters.

Repeat for as many days as you like.

After you've run your experiment, and collected all your data and wrote all your analysis software, you can unblind and actually look what you took each day (and put that in your data collection, too).

Instead of varying each day, you can also randomise to vary entire weeks or months; that's especially useful for vitamins that might take a while to show any effect. (You can pick based on how fast they seem to help with your sluggishness.)

If you have a friend to help you even a little bit, blinding becomes a lot easier.

> ... improve quality of life and reduce instances of disease. You can have both and not have increase longevity.

You can, but wouldn't we expect them to be correlated? E.g., better health and less disease should lead to a longer life (as we assume all non-health related deaths to be random and not correlated to health)
I don't know how DoorDash and other similar services work in the US, but Deliveroo in the UK is always local - bike riders rarely take any longer than 10-15min between the restaurants and my place. All restaurants I can order from are within walkable distance (30-45min tops on foot).

> Out of tens of thousands of companies on the market, you chose maybe ten to apply,

You're joking, right? The question is jarring because it's asked in an interview, for many, after applying to dozens if not hundreds of companies. Not getting too attached to any applications since the majority never even see a rejection email in response, many more will send the rejection months later, and the 1 in a few dozen applications will get to a phone call with a recruiter.

So yes, the reason I want to work "here" is because "here" is the company that responded.
Many parents don't know social media is bad. I've had to convince my partner that it is harmful over many months. She's only now stopped doom scrolling instagram. We finally came to an agreement that our child will not get a "smart" phone until 14. Our child will have access to old school phones and any other less-harmful communication tech. I intend to expose my child to smart phones and computers in all ways that is educational so that they don't fall behind.

EDIT: I would rather not have needed to convince my partner that social media FB, tiktok and instagram is obviously bad and I'd have liked to have some laws to give me some basic protection.
Thanks! In case it helps:
* Multiplying two polynomials as taught in school is in reality a convolution.
* "performing the convolution of two signals in the time domain is equivalent to multiplying them in the frequency domain"
* FFT allows us to convert from time domain to frequency domain
* We use FFT to convert our polynomial to frequency domain.
* If we are now in the frequency domain, we just need to multiply. Faster than a convolution.

Does it clarify the missing step? Happy to update the post with what's missing.
Which is a contradiction, because trusting someone means not needing to verify what they say or do.
What does it do to the psyche, to not be able to trust anyone?
After many years, I settled on a constraint based design philosophy:

1. type checking, data marshaling, sanity checks, and object signatures

2. user rate-limits and quota enforcement for access, actions, and API interfaces

3. expected runtime limit-check with watchdog timers (every thread has a time limit check, and failure mode handler)

4. controlled runtime periodic restarts (prevents slow leaks from shared libs, or python pinning all your cores because reasons etc.)

5. regression testing boundary conditions becomes the system auditor post-deployment

6. disable multi-core support in favor of n core-bound instances of programs consuming the same queue/channel (there is a long explanation why this makes sense for our use-cases)

7. Documentation is often out of date, but if the v.r.x.y API is still permuting on x or y than avoid the project like old fish left in the hot sun. Bloat is one thing, but chaotic interfaces are a huge warning sign to avoid the chaos.

8. The "small modular programs that do one thing well" advice from the *nix crowd also makes absolute sense for large infrastructure. Sure a monolith will be easier in the beginning, but no one person can keep track of millions of lines of commits.

9. Never trust the user (including yourself), and automate as much as possible.

10. "Dead man's switch" that temporarily locks interfaces if certain rules are violated (i.e. host health, code health, or unexpected reboot in a colo.)

As a side note, assuming one could cover the ecosystem of library changes in a large monolith is silly.

Good code in my opinion, is something so reliable you don't have to touch it again for 5 years. Such designs should not require human maintenance to remain operational.

There is a strange beauty in simple efficient designs. Rather than staring at something that obviously forgot its original purpose:

There are two words in Hindi today, Kohl and Kajaal, which refer to black makeup, often made with lead, worn under the eyes. If you look for the etymology of Kohl, you'll find that it is from Akkadian[0]. The Sanskrit word, from where the Hindi word is descended, shares the exact same meaning as the Akkadian word[1], and they sound almost the same. How is this possible, if not for a connection between Bronze Age Indic and Near Eastern cultures?

It is quite probable that the modern categories by which we divide religions, nations, cultures, people, are all flawed when brought into relief as this article does. Social interchange is far more complex than 19th century definitions of national identity.

They can be hugely political. Snowy 2.0 has tripled in price and has been a political weapon between coal, gas and renewable energy investment. It has pretty torrid engineering troubles with tunnel boring. It will be late coming onstream. Some argue the money could be better spent on renewable, batteries and poles and wires.

The Queensland proposal at Kidston has become a pawn between two parties and probably won't go ahead as large, if at all.

Queensland's existing PHES was operated by the coal generator to earn it money in coal, not to reduce pricing in bids by undercutting. The government had to structurally separate it out to get better bidding outcomes noting that it co-owns the coal power station concerned and liked the revenue side as it is.

Pumped hydro can be very useful in "black start" events.
> verifying code correctness is impossible

Somehow, taking into account the state of our industry, yes. But this is not an absolute truth.

I mean, we do have the theoretical frameworks and even tools to come with solutions that allow to proof that code is correct. It’s just that mapping this "know how" with the "how to deal with the expected flow rate feature" is very uncommon.
This study wasn't about it. Do you have one claiming that?
Didn't even need to have the years on the X-axis for the first graph to know exactly when (and why) the underbuilding took off. Great job Maggie.

“It has been found both experimentally and theoretically that, if the aerodynamic force is applied at a location 1/4 chord back from the leading edge on most low speed airfoils, the magnitude of the aerodynamic moment remains nearly constant with angle of attack. Engineers call the location where the aerodynamic moment remains constant the aerodynamic center (ac) of the airfoil” [1].

As you go faster, it goes from quarter chord to half. For a rectangle, the chord length is equal to the airfoil length.

Why quarter? It comes from thin-airfoil theory [2]. (Unintuitively, it holds across atmospheres.)

That prototype/demonstrator (let's not get silly about words here) looks like it's actually flying properly though. Transitions to horizontal and vertical flights and all. They are planning to have the first manned flight end of this year.
A scam would be intentionally misleading people about the ability of this thing to fly at all and then grabbing the money and run.

scam would also involve disgruntled investors trying to sue and getting their money back. There have been a few such cases about investors wanting their money back. But the headline is that Lilium is continuing to raise lots of money and making steady progress to getting their products launched. And those court cases seem to be going nowhere so far. The nature of VC funding is of course that things don't always go to plan.

Just because this company isn't satisfying your need for instant success and instead is following an entirely reasonable path to certification, which is slow for any airplane, doesn't mean it's a scam. By that logic anything is a scam until it emerges fully designed and manufactured on the market. That's not how things work in the real world.

This thing has investors, prospective customers with letters of intent, and flying prototypes.

Nikola is actually shipping trucks at this point too. Yes, they got caught with a non driving prototype running downhill and they got punished for that and the CEO might do some jail time for that. But the thing works now and they are selling lots of trucks that actually move cargo around. A scam would have been if the thing proved to be vapor ware. As it turns out, it wasn't. It was just running a bit late.
Dragging projects out years dealing with bureaucracy, avoiding the actual efficient routes to minimize eminent domain, etc. It’s lots of legal, engineering, and planning work that just wouldn’t exist at all in a country serious about public works projects.

So the costs manifest both as labor that shouldn’t exist, costs just because the project is extended so long (administrative salaries and interest on loans), and costs to buy land from entitled owners.

If it was down to cost of labor and everything else was the same, we’d just pay double and be done in the same amount of time.
What I am proposing is to imagine that after successful but unwise engineering and improvements in hardware, there would be millions of digital humans on the internet, which emulate humans in almost every way, but operate at say 5 or 10 times the speed of humans. To them, actual people seem to be moving, speaking, and thinking in extreme slow motion. And when they do speak or do something, it seems very poorly thought out.

We should anticipate something like that if we really replicate humans in a digital format. I am suggesting that we can continue to make AI more useful and somewhat more humanlike, but avoid certain characteristics that make the AI into truly lifelike digital animals with full autonomy, self-interest, etc.
I think the part of our brains that enjoys music only has short-term memory and is experiencing the pattern-breaking surprise every time, even if you remember the song consciously.

I'd say it's even over time trained to recognize the patters it encounters quicker, so the songs become MORE enjoyable the more you listen to them (up to a point).

Thank you, but no. I enjoy working on a branch and committing small changes at a time, sometimes trivial, sometimes not even compiling, sometimes formatting or whatever the hell I feel like.

When it comes time to review, I squash all those trivial changes manually (rebase -i) and present a clean branch for review.

We could try harder to enforce stricter policies on devs to ensure they're much more disciplined about their initial commits, but what we do works for us. It allows faster iteration and then we enforce squash and merge once ready to go to master.

I don't understand why this bothers some people so much that they spend time ranting "you're using git wrong". If it was wrong, we'd be noticing and change our workflow. But it doesn't feel wrong, so we'll continue to use it.

Flour is not that good for your diet to begin with, regardless of being produced industrially or not. The kind of crap supermarket breads popular in the US, doubly so.

But, to answer you question no, I make the common sense distinction, between food stuff produced at industrial scale, and "industrial produced crap", like things that involve preservatives, food additives, sweeteners, artificial coloring, hefty does of corn syrup, lab chemicals, and other such crap, which can range from the plain shitty ("wonder bread") to the spectaturaly shitty (sodas, gum, doritos, skittles, and on and on).

In other words, I don't fall for thought-stopping arguments like "Ackchyually, just so you know, water is a chemical too, so what's so bad with industrial food-stuff designed in a food chemistry lab vs grass-fed meat, fish, veggies, and fruits?"

I’m telling you as a manager in a company that rewards productivity. We do refresher percentages and bonuses based on perf feedback from leads and peers.

Coasting senior clock punchers get base salary and little more. It’s easy for high performing people with lower titles to pass seniors in TC over a couple of years due to stacking perf bonus stock grants.
These articles never seem to mention the issues with passkeys asthey relate to Apple and other companies like them being in control of you account accessibility. What happens if you're device is list or stolen? What happens if that company decides you can no longer access your account with them?

It's surprising people still consider large scale language models as a key solution to the problem of AGI, when it has become quite clear they will hit all practical scaling limits without surpassing the "well informed imbecile" intelligence threshold.

I have to say, yes, I also do find that extremist.
Yet another statistical analysis of self reported questionnaire about if death can be avoided by something.

How about other measures of one's life before the inevitable? Life quality that is there not only for those with diabetes, cancer or cardiovascular problems having less or more known mechanism that (as far as I am aware) not strongly correlates (yet has casual effect) to the consumption of vitamins. I am the only one tired of these statistical analyses with insignificant deviation smearing billions of aspects together through general public created guided data drawing grandiose conclusions only in titles, while the scope of the title is also very limited despite playing the tune of primal fear to inflate its self importance beyond the content?
They didn't specify what they qualified as a multivitamin, my guess is that the definition is rather loose due to the scale of the study. There's a lot of different mixes of multivitamins in the store. You would buy the one that fit's the efficiency pattern you want to prevent. If your goal is to specifically reduce mortality rather than prevent short term fatigue, you would need to pick the right one.

From what I can tell, they haven't ensure that the long term consumption pattern was consistent either, so they may be mixing people who took multivitamins for a year around the initial study with those who took it every day for their whole life. That would reduce the effect size significantly.

The general advice on vitamin supplements is usually to take the ones you have explicit reasons for taking and to focus more on food in general. This study, while possible useful as a way to debunk highly unrealistic claims of multivitamin effectiveness, doesn't really change the picture here.
I would go one step further: why would the question be irrelevant for a janitor? Let's say you search for a janitor for a high school. You have three good candidates. One just applied randomly. One lives just around the corner, and wanted to find a workplace where he would not have to drive for hours. The third one lives far away but loves interacting with teenagers: for instance, he is a karate instructor in his spare time.

Feels relevant to me. You can apply for a janitor job in a lot of places, so it cannot hurt to ask whether there is a reason to choose this particular one. As other said, just saying "I need a job and this fits my profile" should be an acceptable option.

Let's not pretend that question is what will make or break the interview. I always see it more as an ice breaker to get the discussion started.
So if someone is talking to you, you make them remove their listening device just in case they are listening to someone else?

That usually comes after certification. Which some of these things are getting close to. I hear Delta is eager to start shuttling passengers from their terminals with Archer. At this point, you can start making some pretty informed statements about operational cost too. Battery life span and cost is a known factor. The cost of electricity is a known factor. There might be some nasty surprises with components, manufacturing, or scaling up production volume of course.

But mostly these things are starting to look like they are getting there.

There's basically no evidence anywhere that vitamin supplementation does anything at all for generally healthy people who don't currently suffer a specific deficiency.

If you do find some studies that find some evidence for vitamin supplements doing anything (for generally healthy people), please let me know!

I’d honestly be curious to see if this study accounted for socio-economic class and overall policy around food enrichment or fortification in the regions the participants lived in. I’d expect multivitamins to have a more noticeable impact in places where food wasn’t enriched.
