Something that I started doing recently is to create a "30 second summary" of each important concept, consisting of text and diagrams. I then record a 30 second video where I narrate, using good intonation, the 30 second summary. I also create a hyperlink from the summary to my notes of each prerequisite concept.

This serves three purposes:

1) The act of teaching is one of the best ways to solidify a concept in your mind. It forces you to have a good understanding of it, and forces your mind to produce a good internal organization around concept.

2) It usually takes a while to write + diagram a good summary, and takes a number of tries to get a smooth recording of you speaking the summary (Example: https://www.youtube.com/watch?v=rHc-bog1hhE). All of this "repetition" / time spent with the concept makes it easier to remember.

3) Sooner or later we realize that remembering everything is impossible. Given enough time, concepts will decay in your mind. In the long term, one of the most important things for you to optimize is the speed at which you can re-create your mental model of a concept. Having these 30 second summaries, complete with links to prerequisite concepts, allows you to re-build your mental model of a subject area extremely quickly in the future in a just-in-time fashion. Just like a smartphone is an "extension" of your brain, a note system like I've described here is like an extension of your memory.
YouTube is also a private platform, they can take down your video for any reason at all.

Scientists code better then you do science.

This is simply a consequence Of a weeding out mechanism for those that have no coding skills. The only ppl who get away with no coding skills are important professor with grad students to do the coding.

This isn’t to say that our skills are great, but a generic programmers (I.e. CS majors) science abilities are approximately zero (common, no thermo in an “eng” undergrad???)

So what can you do?

Since you mentioned science and not engineering, I’d ignore the AI advice. Science needs models based on mechanistic understanding of the underlying phenomena. A model that merely predicts is useful for engineers, not scientists.

“materials simulator (eg how can we get a material having a given set of properties)“

This is already done, but of limited usefulness. First the Mtls simulators are far from perfect. Then there is the problem of actually synthesizing the mtls. These simulations are more typically done to weed out bad candidates.

“No immediate financial return”

Wrong attitude. Only an attitude of “no financial return” helps science. That’s not to say you won’t make money off of it, but that can never be a goal since (true) science advances freely (again see the Gaussian jerk vs. Einstein or Landau - who contr. more?)

Instead, focus on making the programming tools scientists use better, easier to use and GPL. GPL is important because an MIT license by itself allows a scientist to use others work while blocking others (see Gaussian).

For example, making python (or Julia?) better would be one of the most important contributions you could make. The matplotlib guy was deeply mourned in science.

You're absolutely right. I've seen memes about the "fashtag", including the ones that do their best to attach it some meaning, but that meaning was so stupid that I didn't even bother remembering it. It's a dogwhistle for the sake of dogwhistles.

What precisely do you mean by “the same problem with epicycles”? You can fix Jupiter at the origin. You use exactly the same equations, except that the sun is using the equation that used to describe Jupiter (with an extra negative sign) and the other planets add in the term describing the Sun’s motion.

Earth is no different than any other planet (or other celestial body in a stable orbit relative to the solar system) in this respect. Hell, you could make the Moon the center of the solar system - the math works just fine.

Got it, yeah as long as we agree most programmers do use the command line. I actually agree that there are hypothetical ways a command line could almost always be replaced, but to me the important part is that most developers choose not to replace it. (And I’d argue that dependence on the command line is actually increasing overtime, with package management, version control, continuous integration, and modern editor features being implement on top of it.)

The question I pose then, is if these things are possible to do in other ways, and those other ways are better, why don't professional developers choose to use them? For example, why isn’t programming on an iPad popular? I.e., where these other methods are literally the only way to do programming on device? Using SSH to program entirely in a terminal is almost certainly more popular for professional developers than any other approach of programming on an iPad (using blog posts about how professional developers develop on an iPad as an indicator).
I didn't interpret the comment quite as you did.

Rather, I assumed it was being (rightly) critical that Buzzfeed news spent such a lot of words and effort on a topic that wasn't especially newsworthy. In particular, it was a frustrating read, being padded out by too many examples and testimonials, when the real meat of the article could have been summed up in a sentence: "Amazon Choice recommendations are algorithmic and not very reliable."

(It seems to be trying to tap into the zeitgeist of looking for a critical angle in everything that Amazon does. Which is weak and clickbait-y.)

Honestly, it's a bad (or good?) example of what the internet has made "journalism" into - and I put journalism in quotes here not because I'm knocking Buzzfeed news as being able to sometimes produce good journalism, but because this isn't one of those times.
Python was already in the top 5 well before the whole AI craze and before pandas was out.

Python has a huge amount of introductory learning material that assumes it is your first language, while most FP languages (Ex: Clojure, Haskell, F#, Scala, OCaml) really struggle in this area. I really like FP, but there is a bit of a steep plateau when learning. If you look at some of the questions people ask in the Python stack exchange, you get the impression that millions are learning it as the defacto first language (I was one of those nearly a decade ago). I try to find similar paths to FP and everything from the tooling to lack of thorough introductory material keeps killing it for me.

Another issue is that from a pedagogy perspective all the "building blocks" in FP are different to what many people already know. If you're used to the imperative/OO paradigm you can move between languages by just learning the syntax to (lists, dictionaries, while and for loops, branching, array access, file IO, and classes). When learning FP you have to learn similar, but different concepts (pattern matching, monads, currying, discriminated unions...etc).

The beginner books that do exist (ex: learn you a Haskell) are nice, but I've talked to many (myself included) that when they finish say "I still have no clue how to program in Haskell". To give another example, I spent two weeks reading a Python book on building text games and when I was finished I was like "OMG I can do stuff". That book covered how all the main data structures could be used with short and fun programs. It also included reading text files, string operations, pickling data, classes, modules..use of the included IDLE IDE. It was great.
The consensus during and after WW2 was that the Germans deserved it. If you start a war expect to get burned.

You don't think that lots of negative reviews are written by people with rather odd expectations?

It certainly pays to take reviews into account, it's just that a soft survey style approach yields more information than a hard rules based approach.
I am too old to have had educational videogames as a child so I have always wondered if they actually were "educational." Do people who played these games as a kid feel as if they actually learned something from them?

(Of course we can learn things from any game but I'm just wondering if people feel educational games were more educational than, say, Civilization)
That "cohorts shift" critique didn't land with me either, until I thought of my own path.

Grad school pushed me way below the -$6k median for the bottom quintile.[0] I pulled that quintile's average down for years, but I wasn't in trouble or part of some kind of social problem.

To be clear -- I don't mean this as a values critique. I definitely want to help those that haven't had the opportunities to succeed like I have, and support charities and programs that I think will have the most impact.

But I still have a methodological quibble. If we want to address poverty, it's important to understand it. For that, we need to separate out the people moving through quintiles due to life stages, and isolate those that are really stuck.

I'm not sure the best way to do that. It'd be nice to see this data separated out by age, I guess, that might be one way.

That is the beauty of free speech. The humorous and playful gives cover to the toxic and harmful, which in turn gives cover to undesired truths and the champions of the suppressed.

A pair of jeans that are not faded, and are clean and crisp, have not been lived in. It doesn’t mean that a faded and torn pare of jeans aren’t just a facade. But a community that lacks the undesirable is necessarily one that lacks the freedom to be undesirable. That would be far worse.

Lessons from React Native Development
As a distinctly mediocre, lazy and easily bored amateur pianist, I've found that selecting the right pieces for building up technique makes all the difference. I only play for my own enjoyment, not to perform a specific repertoire to a concert standard, so I cannot bring myself to practice scales, arpeggios, Hanon/Czerny and the rest. The best suggestion I've ever found is just playing the Chopin etudes (and the Godowsky transcriptions of them, if you can). They are just the right balance of being of immense technical value while still being musically interesting, lovely to listen to and cover almost the entire range of piano technique that exists. Furthermore, each etude is targeted at a particular aspect of technique, so it is easy to pick something that suits your particular needs. For instance, I'm learning op. 10 no. 4 right now [1] in order to strengthen my left hand and improve wrist flexibility at speed (the curse of small hands), and the improvement is palpable, even with very limited practice time.

The other thing I would say is that it really helps to have a goal to drive you. I quit playing piano for a decade and the only reason I came back to it, built up what little technique I had and persevered was because I really, really wanted to play a particular prelude by Rachmaninov, even though it was way out of my reach at the time. Finally learning it after a year or two of fairly hard work was very rewarding.

> points of reference such that it does or doesn't

It's too bad (but not surprising) that you couldn't have gotten a bit deeper into general relativity where even the idea of "points of reference" gets a lot tricker. Even though there's a lot of pop-science talked about "space time" I find most people don't really grasp how really challenging of an idea it truly is.

Newtonian physics and special relatively are quite happy to imagine one observer looking at another from a particular frame of reference. The classic example is of course watching someone driving while you are in a train. Special relativity seems really crazy at first because you realize the length of the car can change if either of them are going close to the speed of light.

But GR does away with this idea that you can understand the universe at all while sitting on a train. In GR frames of reference only exist locally in infinitesimally small units of space and time and are defined by being simple such that all particles being observed move in straight lines. The big insight of GR is that the question "which 'revolves' around the other" is the wrong question because the only way to understand the universe is in slices of space and time where everything moves straight (well you can't ever get 'everything' straight, so even then you just worry about getting it right for a few particles at time).

In GR when you jump forward and land on the ground in front of you, you moved in a straight line the entire time. This sounds impossible because we can't imagine a single frame of reference where we could observe this. And that's what makes GR so hard to understand because the jump forward can only be understood by looking at the way those infinitesimal local reference frames change, but there is no general frame of reference that we can find where we can clearly observe this. In the exact same way that calculus understands a curved line as an infinite sequence of perfectly straight lines, GR understands curved space time as an infinite sequence of perfectly straight frames of reference.

It is, in fact, much more complex than the simple case of trying to understand who is right from the two reports of two observers seeing each other on passing trains.
I remember that time. I was at a (much smaller) completing company and I could tell every time TLC bought another educational software company by the little flood of resumes came in.

At first I thought they were just stupid (I was naive... “don’t they know their catalog will run dry if they aren’t refilling it with new titles?!?”).

Then with growing horror I realized they knew perfectly well, that their company sales numbers were shooting up while their costs were going down.

I thought the payoff would be to milk revenue from the back catalog for a few years until even that was no longer worth the effort.

But then there was the huge sale to Mattel. They’d found someone with billions of dollars to spend without the slightest idea how the business worked (or any business?). I still don’t know why it didn’t matter that the growth was due only to acquisitions and the cost cutting was due to halting new development (like losing weight by amputating your legs). I guess Mattel had a “Barbie” mindset where the popular properties keep producing steady revenue for decades? Still even something like Barbie gets constant updates.

One insight I have:

There’s no way the execs at Brøderbund and all those other companies didn’t understand what was going to happen when they sold themselves to “TLC” after they saw what happened to it. Those execs knew perfectly well they were selling out their employees and the future of the company. There were fat bonuses for the execs and sometimes smaller ones for managers when these deals went down so these people would profit personally while understanding what was going to happen to the future of their company and the people who worked for them.

Thanks, it makes sense.

> focus on making the programming tools scientists use better, easier to use and GPL

That sounds the most natural path to take going forward. Besides looking at existing GPL software and how that can be improved, would you have a recommendation on where to find scientists/researchers open to discussing their needs that could be solved by software? I'll release the software under GPL, but need to know I'm building something useful.
Reddit, the company, actively bans the "red tribe" and promotes the "blue tribe". They've chosen not to welcome society at large, but to push their own political views through selective censorship.
Can we call it the Streistand?
Anything a store promotes is an ad. In the very rare cases of mom&pop stores, it could even be because the product is good. In a typical case, it's because the store needs to cycle inventory, the product is bad and therefore doesn't sell well, or the supplier paid for it.

A rule of thumb for urban shopping is to always ignore "helpful" store recommendations, especially unsolicited ones. They have little interest in doing right by you, and every reason to trick you into a purchase that's better for them and worse for you.
> Firefox isn't doing great right now, but is it doing any worse than Brave?

Maybe in terms of market share as a proxy for success that is true.

As a browser though Firefox has come on leaps and bounds (and has momentum to keep improving), I never switched away from it but used Chrome for dev for the last few years so I have a fair amount of time with both (dozens of hours a week) and Firefox is as fast and reliable as Chrome.

Ironically the one property that gives me issues with Firefox is youtube, they don't fix bugs against Firefox (the white bar header on fullscreen has been in firefox for over a month now and has been reported).

I ended up having to implement a ublock origin rule to remove the header.

EDIT: Mozilla are (to me) so much more than just a browser vendor, MDN documentation is probably my 2nd most visited documentation/help site (behind only stack overflow) because the quality is superb, concise and they quickly mention at the bottom can do this on foo, bar but not fizz which is useful to someone approach 40 because keeping that stuff in my head is well beyond me these days.

Fascinating. Basic physics question: the linked Wikipedia page on barycentre suggests that the further away a planet (in a 1 sun 1 planet system), the further the barycentre is from the centre of the sun. How does that work in the context of the declining force of gravity as a function of distance? I would have thought that the further a planet , the less pull it can exert on the sun. Does gravity not work that way?

H&M is not "the beast". Having kids, I am very thankful for their existence, otherwise merely buying new clothes every year would probably bankrupt us.

Before you say I should buy Second Hand: many kids clothes simply break by daily use. It is already common to give old children's clothes that are still OK to friends with smaller children, so it is not like the clothes are wasted by excessive consumerism.

> [...] to the second most popular party in the nation

The Afd came in fourth in the last election (European Parliament, just about a month ago: https://en.wikipedia.org/wiki/2019_European_Parliament_elect...) with 11%. That's a far cry from taking over the nation, and they seem to be past their peak.

I also don't get the logic how strongly condemning the Holocaust is supposedly a reason for their success. How is your neighbours not loving the flag any justification for hating foreigners, women, and the free press?

Anyway, there are many other countries without Germany's specific history, a long tradition of jingoistic patriotism, and still they have far stronger far-right parties today, i. e. France, Austria, Hungary, Italy, Poland, Russia, the UK, Finland, Greece etc. etc.

Yes, Rocky's Boots taught me the basics of computing. I think having an intuitive grasp of logic gates at a young age made it easier to learn to code.

I also think that I learned a lot from games that weren't explicitly intended to be educational, like planning and independent problem-solving skills.
Headline should include "(2018)"

Interesting. I agree in theory with the call for interoperability, but I am not clear on how such a policy would be implemented. It is also not clear which APIs Mozilla would like to see standardised or created. They do mention the ability to move user data between platforms, which seems like a reasonable suggestion. I am reminded of the effort in the EU to standardise phone chargers. It is difficult to craft a standard without closing some doors to future innovation.

Also, this is the first time I've heard of Rocket (now Firefox Lite).
