smelterdemon··on Shift to electric vehicles will radically change auto factories
The only real difference is the drivetrain, and only enthusiasts really care about the technical differences in ICE drivetrains. Interiors, cargo capacity, reliability, fit and finish, ride quality, etc. will all still differ between BEVs.

E.g. NVH has been getting better pretty much every year despite the fact that car companies have been working on it for decades

smelterdemon··on What Is a Tech Company?
A tech company is a company that is:

(1) Marketed to investors as a tech company

(2) Valued by investors based on the premise that they are or will become oligopolists in their market

smelterdemon··on One Year in San Francisco as a Software Engineer
You're right that the tech industry is by no means uniquely guilty for creating negative externalities or for the negative effects of capitalism in general. And while the other industries you mention have taken plenty of criticism over the past century or so (and continue to get it- it should be easy to find the equivalent negative take on Houston you're asking for, it just won't show up on the front of HN) there is a simple explanation the tech industry seems to be the biggest target: As the fastest growing segment of the US economy over the past decade, it's both the easiest to glorify and in turn the biggest target for condemnation.

There are maybe a few of other factors (some touched on in the article) that amplify the criticism if they aren't causal. The rate of change brought about by tech feels faster than others before it. Houston grew into a square of choking freeways with the oil industry; while SV has old roots the explosion happened in a couple of decades. The other factor is the concentration of the industry makes it a more tangible issue to the people effected. You can understand Big Oil is destroying the world but it's harder to picture than a Google bus in front of you in traffic.

smelterdemon··on Motorists ‘are being misled by autonomous driving aids’ – report
I drive a Volvo S90. I only really use the "Pilot Assist" on the highway, and once you've driven it for a while you can get a sense ahead of time what situations it will fail in.

You're right though the biggest issue is still anticipating what other drivers are going to do. You need to override the system to stay out of people's blind spots or else you'll get cut off or worse. When you stay at a steady speed other drivers seem to forget your presence quicker.

smelterdemon··on Pointer Free Programming and the Future of Nim
That's on the client code. You can't stop callers from doing something stupid (or cosmic rays from flipping bits). At that point crashing fast is preferable.
smelterdemon··on Pointer Free Programming and the Future of Nim
For parameters where you aren't transferring ownership, just use raw pointers/references. If it's a required parameter make it a reference. If it's optional, use a pointer and check for null.
smelterdemon··on Pointer Free Programming and the Future of Nim
Creating objects in invalid states is definitely not idiomatic C++.

I do agree that people are a little too fearful of using bare pointers for optional references, if you're using a linter that will catch possible null dereferences it's often the most sensible technique.

smelterdemon··on Haskell Typeclasses vs. C++ Classes
>the "vtable" (the dictionary of functions) being passed around isn't virtual and is provided per type, not per instance.

This might be nitpicking but vtables in C++ are created per type with instances having a pointer to it.

smelterdemon··on The Mathematical Genius of Auto-Tune
I had always assumed that Auto-Tune had evolved from or was an advanced form of Vocoder (likely from the similar "robot" effect extreme applications of Auto-tune gives).

I've been working on a relatively simple real time music/audio processing project on an Arduino (identifying tempo and using it to create interesting lighting effects for a Halloween costume) and it's an interesting challenge. Extracting any kind of useful information about the underlying musical structure from polyphonic audio is an incredibly hard problem. Add to that limited hardware and the kind of sampling rate you need to capture music (upwards of 40kHz if you want to capture everything you can hear) and you have to get creative.

For active people trying to build muscle or lose fat while preserving muscle mass, studies have shown benefits for up to 2.2g protein/kg bodyweight. Which is a lot of protein and can be hard to come by. Sure, if you're sedentary and not trying to change body composition you don't need anywhere near that much.
smelterdemon··on The Mathematical Genius of Auto-Tune
In 1996 your processor might be running at 150MHz. Using a standard 44.1kHz sampling rate, that doesn't give you very many cycles to get each sample processed to do this in real time.
smelterdemon··on There Are No Houses for Amazonians
Detroit has one of the largest concentrations of engineers in the country. Granted I'm sure a significant percentage of those are specialized in fields Amazon isn't interested in, to say they'd have to import nearly every worker is a bit extreme. Amazon even has a small office in the city already.
smelterdemon··on A Robot Makes a Mean Caesar Salad, but Will It Cost Jobs?
Oh, I'm not optimistic at all that the kind of societal shift I'm talking about will/can happen, at least in any peaceful/gentle way- that's why I said in a best case.

I'm just objecting to the idea that working for a living is necessary for self esteem or self actualization.

smelterdemon··on A Robot Makes a Mean Caesar Salad, but Will It Cost Jobs?
>People left without a job/role in society often don't matter even to themselves -- low self esteem, turning to drugs, alcohol, etc.

I see this argument all the time here, but no one accounts for the fact that we live in a society in which people's worth is largely determined by their ability to secure financial stability. Who's to say that people without jobs, allowed to live without societal derision in a (best case) post work future would be inevitably reduced in spirit?

smelterdemon··on PixelNN – Example-Based Image Synthesis
I wouldn't want to see it used as evidence in court (and I doubt it would be allowed anyway but IANAL) but I could see this being a useful in certain circumstances for generating the photo-realistic equivalent of a police sketch e.g. if you had low-res security footage of a suspect and an eyewitness to guide the output.

smelterdemon··on Face ID, Touch ID, No ID, PINs and Pragmatic Security
Re: the pushback the author got on Twitter; I believe in skepticism towards corporations and marketing claims, but the level of cynicism online towards any new tech idea or product seems a bit out of hand. There's a certain trend, on Twitter especially, of people racing to prove they're either more woke or smarter than the teams of people behind things that are yet to even be released. I mean a "wait and see" attitude wrt the actual effectiveness is good, but I don't get why we need to concoct extreme hypotheticals here suggesting Apple is somehow irresponsible for adding an optional feature.
smelterdemon··on What Monoids teach us about software
I can't speak to the relevance of monoids (I don't have much experience with FP) but to me those examples are helpful in illustrating the definition. It's easy to assume associativity <=> commutativity until presented with counterexamples.
