He didn't just describe the flow state, but also identified the conditions to achieve it. One can modify their experience according to these conditions to enter a flow state. For example, when the problem you're working on is too hard, then first work on a simplified version; or make it harder if it's too easy! When feedback cycle is long, then first make it shorter, e.g., make tests run faster, etc.

I don't get the initial short build time thing. My prior work project took 15h too build from clean - obviously a nightmare. It was due to bad layout of dependencies and a lot of generation. So it is still important to not mess up.

I care mostly about cached build time. A clean build time of eg. 1h does not bother me.

I think this explains the timeline quite well: https://priceonomics.com/the-father-of-the-digital-synthesiz...

> Somewhere in this lull, a tiny Vermont-based synthesizer company aptly named the New England Digital Corporation beat Yamaha to the punch by producing the world’s first digital synthesizer, the “Synclavier.” Though only 20 units were sold at $41,685 each, and they were all reserved for top-notch musicians, Stanford took no chances, and swiftly sued the company for infringing on its FM synthesis patent. From that point forward, the university received a sum of $43 every time a Synclavier was sold.

Yamaha had been working on FM synthesis for a few years already at that point.

Why this was allowed to be patented? This is a pretty much obvious thing to do when you have this kind of limitations.

The real irony is that parts of Kodak where totally on top of digital photography before anyone else. They built both the first digital stills camera and the first commercially available digital SLR. In fact there was a time in the 90s where they owned the (admittedly very small) digital SLR market. However the film side of the business convinced the senior executives to kill the digital side of the business, to protect their film margins.

Ask HN: How do I find a video arcades expert?
Hello,

My brother and I are looking to open a video arcade.
We are interested in getting some advice on the choice of games, types of games (virtual reality, video games, pinball machines...), where is it better to buy the games (US or China) or should games be bought in both countries, how best to deal with the maintenance of the machines ?

Can you recommend us an expert ? Or let us know how we can find one ?

Thanks!

Painting can be very frustrating. Usually the process goes like this: you want to achieve something, you try for dozens of hours, the result doesn't look nearly as good as you hoped, and you have only vaguest ideas on how to make it better on the next attempt. You basically need to love the process and not the results, as the results are going to suck for the first 10 years.

Programming, which purely follows logic, is much less frustrating for people for whom logic is their primary mode of functioning.

The union government claims here and elsewhere that it is administering ‘the world’s largest vaccination drive’. I wish it were true. But China is far ahead.⁰ The website also remarks on a ‘world record of 2.5 Cr+ Vaccinations in a day’: China has reached nearly 3 crore (=30 million) as a weekly mean.¹ Vaccination was an opportunity to shine in comparison to China, but the union government seems to have moved rather slowly (not a fault unique to it):

Purely administrative decision
It may not be viable in theory, but I see it working in practice here.

I live in Munich, Germany. The load on hospitals decreased as vaccination proceeded. Right now, the areas southeast of the city have the highest 7-day incidence in Germany, and even there can still grow by a factor of 4-5 before the hospitals are troubled.

Oh c'mon, that's not fair. You have to tell us what the goal was. :) I'm super curious what a CPU designer wanted with the "laptop that came in the smallest box."

Perhaps smallest box = smallest laptop = they wanted to study the form factor. But does the smallest laptop really come in the smallest box? And did the results of this experiment influence your future CPU design decisions? I feel like this arc deserves its own page.

There's a few striking errors in your post, and this one is the most glaring - in that it's very visual, and also very wrong.

Consider the photo of the Tesla (Model 3) key fob [1]: it's a small car that one does, in fact, wear in one's pocket to show it off to one's relatives or business partners.

Similar with the Tesla App [2] - it shows a desirable car on your phone's screen for the very same reason; the rest is nice extras.

I've worked a bit in OpenSCAD, and although I really enjoy the programming approach to generating 3D designs, it really is limited when compared to traditional CAD software. Being able to visually align an item, or use even basic commands like offset or fillet, are absent in OpenSCAD. Sure OpenSCAD has it's place, but I think that's in the area of procedural generated shapes, and it's not for 3D part or machine design.

For reference here are some of the items I designed using OpenSCAD:

I felt too insecure to ask (stupid) questions previously because, well, people around you are always confident. But with time I saw there's often not a lot behind this confidence, that someone who has a high opinion of himself is capable of really failing in a very basic way, and that most people are more or less the same. So I talk more freely now, and yes, some people are quick to judge. But whatever.
You can use t-SNE (or even better: UMAP or one of its variation) to create a 2D points cloud, and then use something like RasterFairy [1] to map 2D positions to the cells a grid. It usually works well.

In my experience, there is a slight nuance in the frame here. It isn't just that Mr. Luu is "willing to look stupid", it is that he has confidence that his decision making process will on average turn out better decisions than the go-to default strategy that most people employ ("copy the crowd").

Most people, if they rely on their own research and decision making, will do poorly. And even moderately clever people generally do better by copying the rare stray geniuses that float around in polite society. This manifests as an "unwillingness" to "look stupid". It is important to ask "what does stupid mean" and "how do I measure 'looking something'" when this sort of topic is bought up.

I am - and I don't think this is that unusual - willing to go about a decade ignoring the opinions of others if I'm really confident that I have an objectively good idea. It is a high-risk high-reward strategy and not for everyone.
Because despite the very small gain in speed and control being only usable on the straight parts, you still get less fuel consumption, more speed in general, better aesthetics, the pedals and the steering wheel feel nicer and are more responsive, the seats are more comfy, the engine runs cooler and more silently, should I go on?

If with all of these you're still holding on to the old model, then that one is probably good enough for you and indeed you have no reason to buy the new one. That doesn't say anything about the new model, but says a lot about the old one and your needs and priorities. :)
Agree, although with the caveat that if you find yourself deliberately copy-pasting duplicate code, you should consider going DRY immediately. You might later realize the code really should be duplicated (because it is "accidentally alike" rather then "essentially alike"), but it is much easier to turn DRY code into duplicates than going the other way.
My point was exactly that anthropogenic climate change / natural climate change are not A / B, they are not equally valid working hypotheses that we should research. They are more akin to round earth / flat earth.

At some point in the past (say, 80s), yes, they were A / B, and there was significant funding for both. But the results of those studies were clear: it's A. There's no reason to keep investing in B, just like there's no reason to keep investing in flat earth theories. We know the earth is round, we know climate change is man made. There are more important details to keep studying (how bad is it, what kinds of changes can stop it, where specifically will it hurt the most etc). But there's no reason to keep throwing money away on studying a hypothesis which has already been studied and has been conclusively found to be wrong (natural climate change).

I was 50-50, but wedding surprisingly ended up one of the nicest experiences of my life, and there is plenty to compete for that spot. People tend to forget its not for the couple but for everybody else.

Wedding creates additional bonds. I didn't expect it, but it did. You want to have strong bonds in marriage, the more the better, because tough times will inevitably come. Bonds can be created in other ways (ie intense adventure experiences together), but they are different. It also covers things when SHTF - visits in hospitals, inheritance etc.

Divorces are expensive if people make them expensive when going down revenge rabbit hole. It can be as simple as 2 signatures on 1 paper and that's it.

With kids divorce becomes more complex, but then even without marriage its complex depending on local laws.

> If I were interviewing I would much prefer a take home rather than an in person leetcode interview.

It's tricky, because this can vary within one person across time. For example, in my area (DS), i think that the take-home gives the best signal for the actual work (as long as its well scoped).

But, as a parent of a small child, I'd much prefer to just do in-person tests/discussions as it takes less time away from my family.

So it's hard, and whatever you choose will lead to you missing good candidates.

Unfortunately, as in many areas, there's no silver bullet.

Read this description of Diaspora: https://www.gregegan.net/DIASPORA/DIASPORA.html

If that sounds intriguing, you might like his work. He starts with a what-if physics theory informed by his mathematics background. It's heady, positing the universe is a 4-dimensional sphere embedded in a 12-dimensional torus, which allows wormholes to exist and for the protagonists to move through them. From that he extrapolates about what that would mean.

So, maybe not hard sci-fi. Is there such a thing as "math" sci-fi?

There's a scene at the end of the novel. It's short, and not narratively important, so I'm ok with telling you, but it might be a spoiler. If you read the description above and you plan to read it, skip the next paragraph, but it's what really hooked me.

The protagonists discover an artifact that changes slightly as they move from universe to universe. They decide to 'follow' it across the universes, hoping to find the civilization that built it. Tens, hundreds, thousands, billions of universes pass by, and in so doing, they lose connection to their home: "more than seven million broken links, and over ninety billion years of identified [time] slippage". And so they decide to continue, because even if they find their way home again, their home (our, Earth) Universe would be unrecognizable, perhaps dying. At last, when analyzed, the artifact turns out to be (among other things) a massive sculpture "spanning more than a quadrillion dimensions". Collapsing it down to 5 dimensions, so they can get an approximation of what it looks like, "it was a four-legged, four-armed creature, with one arm stretched high above its head... reaching up. To the infinite number of levels above. To all the worlds it would never see, never touch, never understand." That precis does not do it justice, but. Just, astonishing.
