- Individual subs like /r/programming are larger. - HN is ~100x smaller than twitter which is itself not even in the top 10: https://en.wikipedia.org/wiki/List_of_social_platforms_with_...

I've gotten traffic from HN and /r/programming, and the influx from HN is larger. I think it's a function of two things. First, /r/programming is higher-volume (i.e., more front-page links per day). Second, Reddit subscriber counts are not DAU / MAU, it likely includes a ton of inactive accounts.

Yes, it's extremely hard to get an apples to apples comparison of data across different platforms.

I do my best to account for that.

I remain mystified by people who compare HN size as a community to Reddit or Facebook or Twitter (aka X) which are platforms, not communities.

It was impressive how he spotted a bug in his rendering engine and found a workaround for it in realtime! https://youtu.be/rbu7Zu5X1zI?feature=shared&t=693

In larger companies this is how arsonist-firefighter engineers look impressive... fixing a bug they are responsible for while in a highly visible position

> arsonist-firefighter engineers

Brilliant, I’m stealing this phrase. :D

3B1B is doing god's work. May his tribe increase!! I personally have benefited enormously from so many of his YT videos. I wish this is how Mathematics was taught in high-schools, Engg schools. <3 <3

Really? Whats the reason?

Mind elaborating on what that reason is? Otherwise this comment just comes off as a drive-by dismissal…

Pretty much everyone has ideas and opinions on teaching and what would work. It is easy to tell when such opinions are made by people with no experience teaching. In the same way a professional carpenter can tell when some wood work was done in an amateurish way.

Why do teachers do things the way they do? Is it because they are mostly stupid, incompetent people who haven’t thought as much about their job as amateurs have? Everyone has “the solution” but, yet, that great insightful idea doesn’t take off. Is it a conspiracy on our part? Perhaps it’s because that solution doesn’t work at scale.

Efficacy, maximal effectiveness over a large population, and because it works better at scale than other solutions.

Haha, the way maths is taught at university hasn't changed in centuries. Let's not pretend this has all been figured out and perfected. Heck, most maths professors I encountered in my studies could trace their scientific lineage straight back to C.F.Gauss[1] and that's how they taught. Don't get me wrong, some were great teachers, others not so much, but there are valid alternatives to the classic lecture. [1] https:…

What are those valid alternatives that work at scale for a majority of the population?

The traditional lecture does have a lot of value, however, we are also quite certain that the instructional experience can be improved through the addition of visualizations and simulations. This is especially true for interactive visualizations where the learner can ask, "What if ...", experiment, and see the results of their interactions. The lecture format is very old and would not have persisted if it didn't prov…

The vast majority of students never ask, “what if…” The vast majority just want to know the mechanics of doing the problems well enough to pass the test. At the time a student is taking Calculus 1 they don’t ask questions about why it works. They just want to know, for instance, the rules of differentiation. Later in life, when they have intellectually matured, videos like 3Blue1Brown are interesting and fascinating. The vast majority of students would not learn well from 3Blue1Brown type videos.

Python has nested functions which does allow access to the nest...er function's variables. The rest does conform to expectations, you get to use parameters, locally declared variables and globals.

I'm not too familiar with Python, but isn't that just lexical scope, the same as most languages that support nested functions? Starting with the lambda calculus and all the languages it influenced, including even JavaScript.

Correct. It behaves like JavaScript and many other languages. You can't modify such variables in the outer scope from the inner scope unless you explicitly use the "nonlocal" declaration.

Funny I just looked and Reddit says r/programming is 4.1m which last I checked is less than the 5 million unique visitors HN was getting a few years ago when I last saw stats by the moderator and I don't know what it's at now. Twitter works completely differently from most platforms and isn't a unified community.

Where is that 4.1m number from?

I tried to edit my comment and missed the edit window. I was looking at the wrong sub.

R/programming is currently 6.5m, which doesn't matter because it doesn't invalidate my statement about the last time I checked.

If you want to claim r/programming is actually larger now, you need a current citation for HN traffic which you may not be able to find.

And keep in mind it's going to be tough to compare because Reddit members isn't actually a comparable figure to MAU, as noted elsewhere.
