Calif. resident born and raised. Shoes off. However feet are covered with slipper or sandle indoors always. Many homes in ca are built on concrete slabs so walking indoors barefoot isn’t all that comfortable in feet, knees or ankles. Having a barrier between the bottom of your feet and the foundation absorbs and reduces some of this hardness. But outside shoes are for outside only. We have always thought of it like walking in your cleaned laundry. Would you do that... no so why would you consider wearing dirty shoes on clean flooring. Everything, including ourselves are often on our floors so keep them as clean as possible.
We have pretty much all that in Germany. Healthcare is mostly public and affordable, strong social safety net, free childcare in lots of cities, free schools & higher education (and if you/your family meet some criteria, you'll actually get "student loans" that are generally interest-free and you only need to pay back half of it). Want to start a company while unemployed? You'll get subsidies you don't need to pay back to get you started etc etc etc.

Germany's top startups are mostly copy cats, and that's pretty much all VCs will invest in (granted, they're not VC by SV standards, but mostly just investors). We're #51 on that list you posted.

I don't believe that entrepreneurship is significantly encouraged or discouraged by what happens if you fail or whether child care is free or expensive. Imho even regulation and red tape isn't the primary issue, but the local culture's general relationship with risk vs safety. Germans save more than e.g. US citizens, and they don't move to other states within Germany nearly as much (even though it's really not that far, Germany is smaller than California).

> Imagine innovative companies providing that service to better recruit and retain talent.

What you do to get & keep talent (aka "the elite") doesn't necessarily scale to the population at large. If you pay someone $200k, adding $10k for perks doesn't matter as much. It's very different if you're paying them $50k.

Would there be anything illegal about modifying a phone such that the location data it submits looks like some random person in Sheboygan, Wisconsin, instead of reporting where I actually am? Pretty much all I want in a phone is the ability to spoof location data and act as a hotspot for a smarter device (that doesn't have location awareness built in) so I can access richer apps over a VPN in greater privacy.

In case the author of the video reads this: I tried to watch it but after 2 minutes I just had to turn it off as I couldn’t handle that music anymore. It’s extremely distracting when you try to listen to what the narrator is explaining. It’s not that I don’t like background music in explanatory videos, but this music is way too loud and complex to not distract.

Also, considering the video is uploaded to YouTube, I would remove the moving white “stars” in the background. The model itself is very detailed already, which makes it noisy after running it though YouTube’s compression, but the moving stars cause there to be even less bandwidth available for the visualization itself, resulting in more compression artifacts.
If I want some requests resolved at runtime with Next, what are my choices of a production-ready server? I assume `npm start` does not scale very well. What are production practices with Next?

Do you just build your static website and then fetch the data from the browser like React would? Because if so, why would I use Next and not pure React?

SSR frameworks sound very attractive to me due to Kubernetes and hitting internal resources that shouldn't need to be exposed to the world, but I find myself again and again creating gateway services exposing backend services for Ingress.
They take a long time to produce and to consume as well. Video is a neat but inefficient form of communication for a lot of content.

That's funny, because I was following along thinking your point was geographic region doesn't predict performance. Do you find it hard to believe it's possible to have an Indian team with who were high performers in college with fancy degrees and such?
> Doesn't mean we need to pay people for their hobbies.

Well, you don't have to pay anyone for their hobbies.

The salaries for full professors in the humanities (or even STEM fields) can be anywhere from pathetic to half-decent. But that's not why people pursue a career as a professor. These are smart folks, they realize that the chances are slim for staying indefinitely in academia. Many try and many fail. They often to move on to other fields, just like physics and mathematics graduates. It's OK.
Different people have different learning and communication styles.

Some people learn best from video content. Others (like myself) would MUCH rather scan through a written tutorial than sit through a 15 minute video (though thankfully I can watch YouTube at 2x speed).

Some people really benefit from interactive exercises. Others find them to be a waste of time.

A big challenge in creating a good internal learning culture at a company is working out how to best address those different learning styles.
I just looked around Berkeley craigslist yesterday. Tons of places available, month to month, that are mostly fully furnished and at high rents. A lot were nice cottage additions to houses. The rents are not dropping, yet, but it is clear that these were all AirBnB's.

Logistic regression is exactly a NN with no hidden layers and a sigmoid activation function. A feedforward NN with additional layers is strictly more expressive than logistic regression.
Yes, search engines monitor result clicks, bounce rates, dwell times, etc. They do affect ranking. And if you have Google analytics on your recipe site, Google has even more data about it.
Well, you could also use ZBrush for rigging. I think that multi res in Blender can work with up to 10 million polys (or maybe this is a work in progress?), but don't quote me on that.

I don't see why you wouldn't just go for vertex colors instead of UVs. Polypainting works fine even at 10 million works in all tools I've worked with (zbrush, substance painter, 3dcoat). If there's some reason you'd want UVs, you could just bake them to UVs afterward.
I think the variation in “visual age” is too large for “look like 25 by the time we reach 40” to be an outlier.

Excessive smoking and UV light exposure can easily make a 25-year old look older than a healthy 50-year old who exercises regularly, uses sunscreen when they go out in the sun, and didn’t get scars from accidents.

This line of reasoning has always felt incredibly bleak. There's an implied lack of preference for continued experience which can be repurposed to regard suicide indifferently.

It's difficult to take a consistent position that holds both "I don't want to die early" and "I don't care if I die". It requires an arbitrary judgment on what constitutes 'enough' life.

Imagine a pill that gives you 10 years of good health and freedom from aging. No tricks, no evil genies, no monkey paws. It's completely free and universally available. It's not a one time offer. You can change your mind later as many times as you want. How many people would actually refuse that pill and choose to die at a 'natural' time?

Based on how much we spend on medicine, I'd guess very few, and that seems like a clear preference for being alive.
This seems like something that would work really well on the piHole level.
It's not so much that mutation was added to racket. Racket started as a scheme, which has mutation. Some of that, like set-car! and set-cdr! were removed (cons cells were made immutable, though mcons was added for mutable cons cells) set! is one wasn't removed. I think removing set! would constitute a much more radical departure from scheme than what's been done already.
That's pretty much the plot of the story The Man From Earth written by Jerome Bixby. He also wrote a similar story for the original Star Trek series.

The Man From Earth and its sequel are on Amazon Prime Video.

edit: I should have did a ctrl+f man from earth

It's a great show everyone seems to have seen it. I never knew about it until I saw it in my Amazon Prime Video suggestions.
Scheme was defined as an algorithmic language, not a strictly pure-functional one, though it also included some functional features and permitted other functional abstractions to be implemented.

Racket slowly added some immutable data types to Scheme, which was a nice fit for some other Scheme features that had been there from the start, and better for software engineering (e.g., enforce that a user of a module couldn't go and mutate data you were sharing with them).
Well, apart from the cases where they started on the finish line or cheated.
> Every metric that matters to us has increased substantially from the rewrite, and we even identified some that were no longer relevant to us, such as number of bugs, user frustration, and maintenance cost.

That has happened more than I'd like to admit: massive overhaul effort, $new_thing is an improvement in many ways but has all of the reliability and maturity problems of a new system that hasn't gotten years of patches. But the team feels like they have to show ROI on reinventing the wheel, so they massage the metrics to look like an unambiguous success, when everyone involved at the ground level knows it wasn't.
I can't believe anyone is still considering $HYPED_TECHNOLOGY in $CURRENT_YEAR. We at $NO_PROFIT_STARTUP gave it our best shot, but the bugs they mention aren't as small as they seem -- they completely sank the project. At this point it's clear that $HYPED_TECHNOLOGY is falling behind on both adoption and ergonomics to $TRENDY_TECHNOLOGY, which handles these issues in a much cleaner and more scalable way. We'd strongly suggest anyone considering $HYPED_TECHNOLOGY to take a closer look before following the advice in this post.
I am more interested on how effectively we can apply the learnings to new problems. Sometimes it is not straight forward to connect the problem and the learnings. When application is not so straightforward, recalling the memory is out of question.
Great article, even better as a template.

While the slow motion work is very cool, somehow what got me even more fascinated is his earlier "Urban Flow" work with "scan camera panoramas".

This article briefly mentions it at the end, but I didn't understand it until I saw one of his videos explaining it:

https://youtu.be/N0A263UDtqM?t=776

I'm guessing this would be fairly trivial reproduce with a regular digital camera by taking a normal video, and convert it into a "scan photograph" with an ffmpeg plugin or something like that.

I wonder if something like this already exists?

Awesome piece, thanks for sharing. I agree that the key to effective communication is to lower the barrier to writing things down.

In that vein, this piece is missing one thing. It is inherently easier to write something private than to write something shared.

Think of how often you jot things down in Apple Notes, Sublime, etc. as opposed to in your shared space with your team.

A culture of written communication starts with personal (un-shared) notes.

I'm one of the creators of bytebase.io, a notes app that helps people write low-friction, private notes and quickly share with teammates when relevant.

I do actually work on quite low level code. My mistakes are neither millions of euros nor company ending scenario. Just a lot of complaints.

I am not advocating for move early and break things fast. Not at all.

But in my environment I find the need to find a reasonable compromise.

Compromise that can also be having a set of test suites that allow to test things and rollback.

I am the one advocating for "clean code is the one you never have to look at, because it works, not the one that looks nice in the editor".

I understand your point, I understand that we work in different environments, but I also think that a codebase is a living creature that, if left unchecked, will just explode in complexity.

In some environment make sense to tame that complexity, in some other make sense to reduce it!
Not really my field, but I think Riemann had more of an impact on Einstein in that he was looking for a mathematical structure that fit his intuition about spacetime, and he dug up a 50-year old theory and applied it to GR. My understanding is that Einstein was searching for a long time for the right tool, and went down a lot of dead-end paths, before he discovered Riemann geometry.
Can someone explain why 65kb is “a lot?” Even in 2001 on a “56k modem,” that would download in a little over one second.

It’s not like the 65kb here is 1kb for every N characters of text. It’s an overly simplified “hello world” example. The point is that you’ll still see sizes of around 65kb even with much more complexity than “hello world.”

`npm start` is just whatever you tell it to do - eg `node ./src/index.js`, and yes that is plenty production-ready - you don't need any special thing, it's not like Ruby etc

However, regardless, you should really put it behind a load balancer of some kind, and it's generally best to do your TLS termination in that too.

And you'll want something to manage the application and make sure it's running etc as normal. Usually the cleanest option is to have it wrapped up in a Docker image being managed by an orchestrator, but there's also options like pm2
Irrespective of his intentions, or the quality of his work - which seem quite laudable, both his tremendous wealth and the political power of his foundation play into fears many have that the world will degenerate into an authoritarian, pseudo-technocratic plutocracy.

Capitalism and industrialization have made replaceable widgets of most workers. Many employers view their labor as expendable, reward incompetence, and exercise undue or (seemingly) arbitrary levels of control over how their employees live.

When the architects and winners of such dehumanizing systems, who wield power greater than that of many nations attempt to bypass traditional gates to power and directly influence public policy (especially policy concerning people's bodies) because they 'know' what's best, even with the purest of intentions, people have the right to be suspicious and concerned.

It also doesn't help that Gates seems to favor the diminishment of individual nations in favor of a stronger level of global governance. It's not popular with a lot of people, and on the fringes can even be taken as a form of soft treason.
I believe the most impactful thing you can do is drastically reduce caloric intake - like by 50%.

I've had good luck with recipes from https://www.taste.com.au/ and https://www.bbcgoodfood.com/

Alternatively, if you want super barebones, go buy a copy of Escoffier's https://en.wikipedia.org/wiki/Le_guide_culinaire (or an English translation thereof). It's arguably the definitive cookbook and the recipes are extremely terse, some just a couple of lines long. (e.g. "Take recipe A and recipe B, substituting X for Y.")

"Escoffier's introduction to the first edition explains his intention that Le Guide culinaire be used toward the education of the younger generation of cooks. This usage of the book still holds today; many culinary schools still use it as their culinary textbook. Its style is to give recipes as brief descriptions and to assume that the reader either knows or can look up the keywords in the description."
I don’t understand. Not from your comment history either. What’s the problem disqualifying all studies? The Stockholm one is the one I’m most familiar with. It used a test with specificity over 98%.
Predictive power depends on the prevalence, but as the floor of immunity you can use any PCR study for active infection. In the case of Stockholm there was 2.5% active infection over a month before the sero study that showed 10%.

Obviously if a poor test with 85% or 90% specificity is used and you have low prevalence then you get a poor result. But if you can peg the floor of the prevalence at several percent and use an accurate test then what’s making the results useless?

But even disregarding sero studies, you can draw some conclusions of immunity from death numbers. E.g if assuming a 0.5% IFR with 1600 dead in 2100000 you would have 15% immunity (assuming everyone infected is immune of course). IFRs so high that they yield under 5% immune (basically IFR over 1.5%) aren’t consistent with observation.
I just commented before seeing your mention of it.

Although I didn't realize until I commented that Jerome Bixby the author of The Man From Earth was also a Star Trek writer.
A typical Delphi app might have done that, but a selling point of Delphi was that it had data binding.

> How is the work in deep learning helping us understand the nature of intelligence

Neural networks performance on a problem is a benchmark of its real difficulty. It gives us insight, a new perspective.

In millennia of deliberations what have philosophers have discovered about the nature of intelligence? And then .. a neural net beats us at all board games, another can solve differential equations, another can translate, another can see, and so on. Have we really not learned anything by these inventions?

Another advantage of DL is that it frames the problem of intelligence in mathematical concepts and rigorous evaluation.

I, for one, have reconsidered all my spiritual beliefs after learning about the agent-environment-reward model of reinforcement learning. A new way of framing the agent and life, so parsimonious and powerful. And it does not require a soul, or a god, or anything outside out real environment, and yet can explain so much.

The whole machine learning paradigm is another powerful concept through which we can understand how we might function. Previously you might wonder how emotion, thought, sensation, imagination and will relate to each other. Now we can understand how they might be implemented and wired together, and what principles support their function.
What is special about wave 2? Wouldn't 3...n behave the same way and result in stability?
'Specificity and Sensitivity' are new words that are now going to enter the public consciousness with regards to testing.

Before Iraq War 2, in 2003, absolutely nobody knew the difference between a 'Shia' or 'Sunni' Muslim, and then it became more common knowledge.

It's neat to see how these events shape awareness.

Now every time a Nurse does a test, people will ask "What's the specificity?!" which can be a good or bad thing.
