helen___keller commented on Safetyism killed playtime   unherd.com/2024/01/how-sa... · Posted by u/jseliger
helen___keller · 2 years ago
I lived a pretty “safe” childhood, and was basically addicted to video games from 5 years old (when the Nintendo Gameboy was released), but notably I still experienced plenty of boredom and unstructured play.

I had a friend 10 minute walk down the street whose parents enforced a certain number of hours outside per day. So he would call me on the phone, we would meet halfway, and then we would wander around the sidewalk and talk about video games or make pretend imaginary things.

I can only imagine in todays technology landscape I would have preferred to stay home glued to YouTube on my iPad instead of seeing my friend; beating Pokémon Red for the 100th time didn’t quite have the draw by comparison

helen___keller commented on College Is All About Curiosity. And That Requires Free Speech.   nytimes.com/2024/01/24/ma... · Posted by u/mitchbob

In a pre-internet society I think universities rightfully earned reputations as being the closest place to a true bastion of inquiry and free speech. There were conflicts and exceptions over the years, but generally universities would lead the way on introducing, refining, and testing the radical discourse that might later go mainstream (or not!)

On the contrary, in the 21st century I don’t think universities own this privilege nor should we pretend that they do. Radical discourse is now almost exclusively introduced, refined, and tested on the internet, then later brought to other venues (including universities). And this is for good reason - the internet is simply more efficient and with less barriers.

To that end, as someone who is not a university professor, I frankly could not give a crap about the state of universities wrt free speech. Every student carries a phone in their pocket with a cellular connection that offers all the free speech and inquiry they could want.

Posted limit detection seems reliable in existing cars, both self-driving and not; is there some reason to believe this will be any less reliable than other safety technologies?
helen___keller · 2 years ago
I live in Boston and my car’s HUD displays this information (speed limit and such). Sometimes it gets it wrong despite living in a major city center. Once my car even alerted me when I was going the wrong way on a one-way — except that I wasn’t. I can only imagine in deep suburbs / rural it is even less reliable.
helen___keller commented on Meta's serverless platform processing trillions of function calls a day (2023)   read.engineerscodex.com/p... · Posted by u/jbredeche

Sorry this is going to be slightly tangential to the primary topic of this post. But does anyone work on backends that heavily utilize a serverless platform? To be more specific, backend (micro)services that embrace serverless fully (for example AWS Lambda, Dynamodb, StepFunctions, etc) and minimal usage of any ec2/container based deployments in the architecture? And to be clear, I'm not talking about some small bot or single internal app running on a serverless platform, rather an entire complex core business product or service that embraces serverless architecture -- think Amazon Prime previously using AWS Lambda type stuff.

I'd love to know people's (objective if possible) thoughts, experiences and opinions on such an approach.

helen___keller · 2 years ago
I’ve worked on a product where half the backend (basically, the control plane but not the data plane) was completely serverless: lambda, DDB, step functions, api gateway

I think it was generally convenient as being very low maintenance. The only availability canary alarms are when the underlying services go down, which is almost never.

Debugging and running locally are the weak points. Eliminating an entire class of things to think about (container health, scale in and out, and so on) is very nice. Since it’s a control plane, tps and costs were low.

This is awesome to see that it's possible. I've always wondered about the same sort of concept, but instead it would be trying to use Crystal to run the latest Rails version. I lack the time/energy/knowledge to try it, but it would be interesting to see how close you could get to either power or port Rails to Crystal, and if it would even be worth it (in terms of speed and type safety, etc).
helen___keller · 2 years ago
My understanding is that this tends to be difficult because certain really-dynamic-stuff that Ruby offers (effectively metaprogramming) are not supported by Crystal, but are heavily used by Rails.

On the other hand, Amber offers a look of what a Crystal rewrite of Rails would look like

fransje26 · 2 years ago
From the landing page (and trying a few tutorials):

https://crystal-lang.org/reference/1.11/index.html

I couldn't quite determine the reason of being of the Crystal language. Could someone with experience with the language explain what is its appeal, and why it would be worth trying/learning?

Thanks!

helen___keller · 2 years ago
Crystal is basically taking Ruby and adding compilation and a strong static type system.

I enjoy writing it but don’t think there’s any particular reason to try/learn it, unless you happen to also be a ruby dev who prefers compiled, strongly typed languages.

I wouldn't characterize Leetcode interviewing as being biased towards those who recently took an algorithms class - it's biasing in favor of those (of any level of experience) who are willing to spend a few months practicing Leetcode.

I thought that Google/etc had at least dialed this back a bit, or maybe just dialed back the "how many gas stations are in the US" type questions, after realizing this wasn't the best predictor of good performance.

> or maybe just dialed back the "how many gas stations are in the US" type questions, after realizing this wasn't the best predictor of good performance.

These problems (known as fermi problems) have been out of vogue for over a decade now. Google is one of the companies that pioneered algorithm-centric leetcode problems as a replacement for fermi problems.

Leetcode problems are not hugely useful outside of the data given by solving a fizzbuzz. Rather, it’s just another excuse so interviewers can convince themself a person is smart, call it signal, and justify a hire.

The last time Google gave me a job offer, one of my interviews was literally a souped up fizzbuzz - straightforward imperative code with no trick, no complicated algorithms, and no fancy data structures. I suppose that may be the reason I got an offer, that I didn’t need fancy algorithms that I hadn’t prepared.

Ultimately it’s impossible to know if someone will be a good hire from an interview. Being a good engineer requires a bunch of traits that simply can’t be tested. The leetcode interview, as I see it, acknowledges this weakness and instead chooses to filter out low-effort candidates, as anyone persistent can practice leetcoding and interviewing (in theory).

helen___keller commented on Hertz to sell 20k EVs in shift back to gas-powered cars   bloomberg.com/news/articl... · Posted by u/saltysalt
helen___keller · 2 years ago
Over Christmas I flew to another city and rented a car for week. Hertz had great deals on EVs but not so great for ICE so I specifically avoided hertz and went with Avis instead.

I like EVs and have a charger at home for my own car, but maybe due to that I also understand the difficulty of finding a reliable charging situation in a new place. On top of that I was visiting and parking at my parents house, and they don’t have a charger installed.

It's appealing to authority without having to even do the absolute bare minimum of mentioning what the authority you're appealing to is. Is the authority some person's blogpost? Is the authority the FDA? Who knows. "The science" is the authority, whoever that might be, which doesn't mean squat.
helen___keller · 2 years ago
Yes it’s laziness. It’s essentially equivalent to hearsay without proper citations. However it opens the door to less lazy conversation for those who care to ask for sources, and most importantly it sets the baseline expectations that those sources will be grounded by science and not like, my reiki teacher told me kids should wake up after 8 am

There’s something to be said by beginning a conversation with a shared understanding of what is considered a reasonable ground truth.

> This map shows which parts of the U.S. ignore the science.

I'm starting to dislike the phrase "the science", since I usually hear it used as a conversational bludgeon. The American Academy of Pediatrics recommended 8:30 AM as a minimum start time, that's not the same as "the science" definitely saying one thing or another. I don't have kids, and don't really care when schools start, so this is less a comment about that as it is about how annoying "the science" is as a phrase, how it's not a good description of how science works, and how it's usually misapplied to end conversations in favor of your prior opinion.

This is a nitpick at best. From outside a given field, one generally has no option but to pick one or some sources as authoritative and refer to them (or to declare no source is authoritative).

In other words, if I say “the science says XYZ” this is shorthand for “my preferred authoritative sources of information on the relevant field assert XYZ”

Can this be incorrect? Yes. Is this often used as a bludgeon? Yes, and reasonably so: without piercing the research veil, what discussion could exist besides disagreeing on a sources’ authority?

If I say “the science says kids shouldn’t wake before 8 am”, and you respond with some neuroscience argument that childrens brain can adapt to waking up before 8 am, you are essentially making an off topic argument: I am referencing an authoritative position, not arguing why that position is correct. In that sense, yes, I am applying a bludgeon; and I right well should, because I can’t have a meaningful engagement with your scientific position anyways.

I see your sentiment often and even though I agree that usage of “the science says” is a poor description of how science works, nonetheless language is an evolving construct and “the science says ___” is a mainstream construct in English language dialogue at this point

There’s nothing wrong with appealing to authority. Often times it’s the best we can do. Sometimes authority is not sufficiently convincing and in such situations it’s fine to point out that whatever “the science” refers to needs more evidence supporting their claims
