> If a software engineer enters industry without knowing linear algebra, odds are they'll never be a data engineer in a serious ML project, or even more so, work on serious ML themselves.

Linear algebra is a lot to learn[1], but I think it would be possible to pick up the material on the job, given enough time dedicated to it (like a month, not a week).

Similarly for pre-calculus (highs school math) and calculus.

I guess it does add up though, and if you're missing 5-6x of these fundamental building blocks and you have to fit a year's worth of math learning in between work, meetings, and other life obligations it can be tough.

We were an all-Java shop and we were considering how to make our application a SAAS cloud application. Our senior engineers read this book. They all agreed that it was very educational, but the conclusion was that Java concurrency in practice has too many footguns, and so we ended up adopting Clojure.

I think modern Java has better support for it, but if you've got mutable state spread throughout your application you're going to have a hard time no matter what.
> Plenty of people in our age do entertain the monstrous dreams of power that Mr. Lewis attributes to his characters, and we are within sight of the time when such dreams will be realisable.

I love this statement. It seems quite obvious to me, as it did to him, that out of a planet of billions of people, some of those would be power hungry and organize themselves together for better carrying out their schemes. The rest of us should be vigilant in preventing them from rising in power, since they usually have little empathy for the rest of us.
However, I think it’s actually easier to change the clock than to change the norms. (Which is silly!)
How to Plan Your Life?
Surely it depends on latitude and where you live in a timezone (as well as individual preferences). If Boston were to stay in Eastern time (and it probably would because New England switching to a different timezone than the rest of the east coast and an hour further from the west coast has its own problems), the elimination of DST would move sunrise back to about 4am in midsummer.
Yes. It is dogmatic, not scientific, to suggest that a paper is worthless because the authors didn’t frame their argument under some set of axioms you just really identify with, conceptually.
And remove it from anything but your primary residence that you live in. Allow the homeowner to roll the tax until sale, or keep it if they stay in the state by buying another house. Make it income based as well. If you’re making good money, you’re not a senior that can’t afford to stay in their home.

The problem for novices is that a program that behaves correctly looks a lot like a correct program. Until one day it doesn’t.

And because you’re in production and getting random spurious failures, the panicked (but common) reaction is to wrap every shared resource in a synchronized block. Which makes an incorrect implementation worse but possibly correct.
Cruise control doesn't require you to drop your attention to driving. It simply relieves you of the need to keep your foot on a pedal.
The problem with this argument is that it relies on people to be altruistic, which I suspect is already negatively correlated with mask wearing.

I'm not disagreeing that the real numbers have no physical basis; that would be silly. I'm disagreeing with the absurd claim that "uncomputable numbers … in the guise of string theory obtained a death grip on fundamental physics". The real numbers are used in every single part of physics, and physicists do not care to distinguish between computable and non-computable reals, because that makes the theory much more complex with no known practical benefit.

I also wish that the person I initially replied to would expand on their vague claim that

US culture is driven by lack of social interaction. People in rural areas have few interactions with others and don't like rules that limit their own immediate freedoms (to not wear masks, to discriminate, etc.) to keep society safe and in harmony. Due to this effect, older big cities are more "European," newer cities are less "European," and outside of cities, you'll see a lot more people range from "but my freedoms" to actively antisocial.

Here, I'm using "European" in the "Western European" sense like you presumably are. Eastern Europeans have an anti-Communist bent that resembles rural Americans' behavior.

What benefit does getting rid of timezones get us?

Sure, it would be 9am GMT everywhere in the world, but it would still be "middle of the night" or "early morning" or "late evening" just the same. Everyone would just call that 9am GMT.

If you lived in London and wanted to talk to someone in Hong Kong, you'd still need to figure out what time makes sense for both of you. It might be 12pm GMT in London and Hong Kong, but your Hong Kong colleague is fast asleep at 12pm.
Even though both you and Orwell dislike that aspect. I think it is crucial to the books. There are many other good books without that aspect, including 1984. But a key part of the book is the hopefullness in asserting that it is not only by our own strength or insight can the evil things we see around us be overcome. A major point of the book is that evil does exist, conspiracies exist, but that good will triumph because there is something special about good. 1984 ends in a very different tone, both make good points. The variety is good.

I'm surprised how much 1970s news is hard to find references to. The 1978 Tractorcade remained forgotten until just a few years ago.

There's still not much on the US domestic terror attacks (100s/yr), during the early 1970s. That one has a vibe, as if no one wants to discuss it.
This was different. They tried DST all year around. Russia also tried this in 2014 and also failed.
Scientific studies have not proven that masks are effective in limiting the spread of the virus. Quite a lot EU countries suggest they can do more harm than good if used sloppily. Masks and covid in the US have become political issue riddled with pseudo science from all sides.
I've been thinking recently about tradeoffs between (agility / resilience / adaptability) and (efficiency). It seems to me that so many orgs' attempts to adopt "Agile" practices are motivated by a desire for increased efficiency per se. Which seems paradoxical. I'm not trying to get into a "one true Scotsman" debate about what Agile really means, but what I keep seeing is an overemphasis on process that runs counter to the heart of the manifesto. IMHO that's the crux of a lot of dysfunction. V. interested in others' thoughts here.

>Specifically things it's stuff for firmware updates on stuff like Shimano Di2 or other hardware devices.

As someone who dabbles in alternative mobile OSes, it's always frustrating to me when more and more products require using Apple/Google services for basic functionality. I try to avoid buying devices like that whenever possible, because they just lock me into those ecosystems.

The Amazon app store is an option, for things that are available there. It's not everything, but it feels like there's a decent selection there.

That said, for those apps that are only found in the Play Store, there are third-party clients like Aurora Store: https://f-droid.org/en/packages/com.aurora.store/

(Warning: possibly against some part of the Play Store ToS and Google is notoriously opaque regarding enforcement. Use caution.)

That, unlike e.g. the Play Store, should be installable normally as any other Android app even on compatibility layers like Anbox. This probably isn't super polished yet, but I know there's work being done on using Anbox for Linux phones and it seems to work: https://social.librem.one/@dos/105119691527269967

But yeah, personally I'm planning on 1) keeping an older phone around for the things that absolutely need it and 2) avoiding things that absolutely need it as much as possible.

The problem with the purely biological perspective is that it's too narrow. Psychology matters too.

The benefit of an extra hour of light in summer evenings is measured in happiness. You can read a book in the park, play frisbee with friends, eat outdoors with family, with all the happiness that summer light produces.

Nobody's measured it, but I have to believe that the increased happiness, reduced stress, and therefore increased health has got to far outweigh any small effects on circadian rhythms.
I understand the reasoning but I think any architect not using the absolute best tools available to them at any given time is shooting themselves in the foot. Costs associated with subscriptions are negligible for full time professionals.

I think the rise of FreeCad is good for amateurs or part-time architects, and I hope one day it can rival others in the industry, like blender did for modeling, sculpting, composing and FXs. But when it comes to BIM, I'd rather have an architect that uses Autocad than one that uses subpar tools.

There’s more studies than controlled ones.

Sociological studies strongly suggest that masks do work.

For example, there was a recent study that compared COVID hospitalization rates of districts in Tennessee that had mask mandates vs those which didn’t and the areas with mask mandates had significantly lower disease spread.

It's still the same swing in sunlight time, just masked by changing the clocks. Some people will prefer sun in the morning, others in the afternoon. The answer is to allow flexibility of schedule to accommodate preferences, not switching clocks. It doesn't do anything other than mess with routines. Daylight is not saved, or extended.

Regulation, or more accurately piss poor market design is precisely is how we got into this stupid mess. A big reason why we are here is because we first tried to limit the profit margins on the marginal cost of power/transmission which then incentivised utilities to go big on cap-ex because thigh the profit margins there were capped too the mangitude of expenditures weren't. So of course we turn around and start specifying how they can spend it when then incentivised them to cost cut and defer maintenance because that's what was most profitable given the now extreme regulatory barriers to entry.

And then of course there's the when Enron manipulation that was also just as much due to regulators not allowing the market to install new capacity where needed and forcing fixed pricing on retail distribution.

What we really need is a complete market and regulatory transition to something more sane like texas model of separating things into a generation and distribution market with more lightly regulated players.
It's shocking, especially on a scientific forum like HN, that people get so triggered over being asked to wear a teensy extra bit of clothing that might protect those around them from dying.
Remember, the other side is saying the exact same thing: "There is no reasonable discussion to be had with people that deny freedom, want to take away guns, promote socialism, accept killing babies, and refuse to condemn enemies."

Nobody is willing to even come to the table anymore because of how totally wrong and evil they see the other side as. Which is kind of the point of the article.

The headline says "masks work", then the article redefines masks to exclude the things that many people are wearing, and then adds further criteria that rules out most other people. It then fails to take into account research that shows that cotton masks become saturated with exhaled moisture and perspiration, and that stops their filtering properties. It also fails to take into account reductions in social distancing or handwashing.

So, yes, if we have a tight definition of both "masks" and "work" we can say that masks work. But we don't care if a piece of fabric can catch droplets, we care if public use of masks in a pandemic helps slow the spread of that disease.

Are we really having this discussion on Hacker News? As Hackers we should all be MATHing and SCIENCEing

https://www.nature.com/articles/d41586-020-02801-8

This article has some good links to studies and articles, some math and science.

It also points out you don't even have to science very much, there is lots of anecdotal evidence that shows that in gatherings where masks are worn, transmission is slowed.

Lot's of other factors play into that, but you only have to math a wee tiny bit to realize that properly worn masks can help fewer people be infected, and therefore fewer people will die.

MATH.

This has some nice visualizations based on anecdotal evidence and statistical analysis and compares transmission rates in different settings given the variables of masks wearing vs. no masks and ventilation vs no ventilation, while also taking into account surface based transmission.

We have lots of RCTs on mask wearing (mostly in healthcare professionals) and they struggle to find a benefit.
