jtanderson··on Show HN: Saunas lower nighttime heart rate more than exercise (n=59,000)
Just as a discussion point: how do you think these effects would translate (if at all) to regularly practicing hot yoga, say around 100-105F? Intuitively, it would combine the effort + recovery, but probably not enough time elapsed in the same session for the sweat benefit during muscle repair?

jtanderson··on "None of These Books Are Obscene": Judge Strikes Down Much of FL's Book Ban Bill
I can’t quite read this without feeling there some significant over-generalizations and assumptions being made. My experience with people of various races, cultures, and backgrounds has not exhibited any unilateral caste system mentality. I’ve spent plenty of time in academia and, while it certainly has issues, has not been quite so dystopian.

In the end, if we’re just comparing anecdata, this isn’t going to be productive.

jtanderson··on "None of These Books Are Obscene": Judge Strikes Down Much of FL's Book Ban Bill
Is your example here a bit oblique to the point? I see this more of a failing of the people to properly appreciate and discuss/process the contents of the book, and as well as, in my opinion, socially overcompensating for the diversity in the room?

I definitely see your point around a lot of people trying to be so inclusive, they end up being somewhat racist. But I see this more of a lack of proper cultural empathy/education -- go figure, Dunning-Kruger is everywhere all the time. But as you said,

> This law is about what books are in public libraries.

So why would we ban the books, rather than encourage reading them and having the more meaningful discussions focusing on heritage rather than identity?

As a slightly more abstract aside, identity anything to me is a slippery slope because it will always automatically encourage one to make assumptions; it's a mental shortcut to say Person A == Person B iff PersonA.identity == PersonB.identity. Given that education is hard, learning is hard, and life is hard, I think we need to at least emphathize and appreciate that teachers and the the education system in general need to often fall back on these sorts of mental shortcuts. But that's we need to really invoke our right, privilege, and duty of grassroots participation. Why not walk into that book club that's overcompensating and help them learn what is making you uncomfortable? You might be surprised at how ignorant they were of their own mistakes and that they're willing to learn from your perspective.

jtanderson··on MongoDB deprecates Atlas Device sync
Got it, this is very interesting and informative. I look forward to learning more about Ditto as I experiment for my migrations away from Realm.
jtanderson··on MongoDB deprecates Atlas Device sync
Thanks for the reply! Will definitely be looking into Ditto as a migration option. What would you say the main benefits are of going schema-less? In this context does it more mean that the client is responsible for serializing/de-serializing into the correct data structures? I'm browsing the docs already but any extra information would be helpful, particularly around handling evolving data needs, import/export, client sync, etc.
jtanderson··on MongoDB deprecates Atlas Device sync
Brutal :') As Firebase is a Google product it's pretty far down my list in terms of reliable alternatives. But I may check it out as well after I see how a migration to Ditto looks.

Found this additional news that it will possibly be merged into Ditto: https://www.linkedin.com/pulse/meet-ditto-company-replacing-...

Anybody else here using this actively? What are your migration plans?
jtanderson··on Computer scientists invent an efficient new way to count
That is conventional set subtraction notation. "Assign to X the same set minus all elements of the set {a_i}".

One example source, but it is pretty common in general: http://www.mathwords.com/s/set_subtraction.htm

Given the topic of the paper[0], the footnote is especially charming:

> the authors decided to forgo the old convention of alphabetical ordering of authors in favor of a randomized ordering, denoted by r⃝. The publicly verifiable record of the randomization is available at https://www.aeaweb.org/journals/policies/random-author-order...

jtanderson··on Interpreting neural networks through the polytope lens (2022)
There are many interesting efforts — going back quite a few years —- to this goal, many of which in the PAC setting (which automatically means MLP is out, for theoretical guarantees). E.g [0]and its related references come to mind as an interesting place to look into it!

jtanderson··on Google's sidebar for rust is the programming language
Not for me -- even in private mode, not totally sure if that makes a huge difference. I get the Rust survival game.
jtanderson··on Things I’ve learned in my 20 years as a software engineer
While I agree, I think the essence of this comment is that the converse of OP is not true, i.e. "you should trust a senior engineer that has strong opinions". As a sibling pointed out, it's sort of two steps: 1) make sure they have opinions, then 2) ask yourself if those opinions are that of a fan-boy or somebody who has been around the block enough to know a thing or two.
jtanderson··on “I just got a copyright claim for *TYPING ON MY KEYBOARD*”
I guess you're getting downvoted because people didn't realize you're also the tweet author.

So you can confirm that you did lose ad revenue because of the claim and really are just stuck until somebody steps in and reverses it? Or is it as described in the YT terms linked in another comment?

If yes to the former, that's horrifying.

jtanderson··on “I just got a copyright claim for *TYPING ON MY KEYBOARD*”
Also in the case where the claim is overturned, is there really no recourse for the original author to get that lost revenue back?
jtanderson··on Crosby, Stills, Nash and Young’s lost album, Human Highway
If you're still looking, drop me a line! Those recordings are, in my ears, solid gold :)
jtanderson··on Crosby, Stills, Nash and Young’s lost album, Human Highway
I feel this. One of my favorite artists, Ray LaMontagne, has entire albums that he has apparently (due to essentially rumors and, at some point, wikipedia) worked hard to completely remove from the internet. They're from his early days and a little different in terms of his style and voice, but I never found anything definite about the reasoning. However, these albums have some of my absolutely favorite material of his, far more than what you can find on even YouTube now and I was fortunate enough to get some of the tracks digitally years ago and hang onto them. Some of them have even been covered more recently and become pretty popular.
jtanderson··on Sneak Peek of 0 A.D. Alpha 25
Full changes here: https://trac.wildfiregames.com/wiki/Alpha25

Been at least five or six releases since I've messed with it, but seems like they're still going strong! The new AI system seems to be paying off with all the small improvements to, e.g. domestic animals fleeing when attacked.

jtanderson··on Computer Graphics from Scratch
This looks really great!

I'd also highly recommend Ray Tracing in One Weekend[1], which starts you out with literally just a c++ program to dump bytes into a file which can be opened with most standard image/document viewers. Then you don't have to think about or set up any shaders before you can start to experiment with the rendering algorithms.

jtanderson··on Show HN: Are you playing your violin (viola, guitar, etc.) in tune?
Very nice work! There seem to be some issues for me with the lower strings on guitar: the low E registers as a B, for example. Higher strings seem to work well though. Not totally sure what's going on, but could probably be attributed to mic quality :)

Edit: after more playing around (heh) it does start to pick up the almost-E notes, F, G, etc. but is a little inconsistent. I tried monitoring the mic and even recording to play back what got picked up, and it sounds just as clear as the higher notes. Maybe something numerical happening in the Javascript fft?

jtanderson··on MeteorJS Releases v2.0
Same here. I had actually thought they were not planning to continue it, but when I went to check on that I was (pleasantly) surprised to see this release.

I had a ton of fun making some interactive tools for an one gaming community back in the day.

jtanderson··on Earnestness
It seems to me that the perception of boringness can come as a result of earnestness being very niche/focused. Your example is a great one! But if anybody who is not a fan or doesn't know Borges, they would probably find a person earnestly passionately about his writing quite boring -- as one can only have the time and mental energy to be truly earnest about so many things.

In contrast, GP's example of popular people are likely those who are good at faking that kind of deep interest in many things, tailored to their present company, so that they attract a few people from many different crowds. Of course, this is based on my own experience only; in certain circles I can feel quite loquacious and come off as extroverted -- usually because of an earnestly shared interest -- but in most cases I think I come across as boring or even introverted!

jtanderson··on Building an artificial sun that looks realistic [video]
You'd still have to deal with the glare and chromatic aberration from the mirror sheets. Also the area covered would still be confined to the size of one sheet and you'd have to make a "bank" of them to cover any reasonably large area.
