LeftHandPath··on Porsche, Ferrari e-fuel push at heart of EU engine debate
I do agree that we can optimize for the cities, but the general attitude towards the people who are going to be worst affected by the ban of ICEs is to look down at them and laugh - as Colbert exclaimed, "I don't care if gas goes to $15 a gallon, because I drive a Tesla!" That's not a healthy approach (and note, I'm not accusing you of doing this, I'm just explaining the way this issue is being approached by the upper class at large).

15% of the US is about 50,000,000 people. To reduce the fraction, that's 3 in 20 Americans. That's a lot of people to just hand-wave away and leave behind. These are people, not dinosaurs. They also control our food supply. I think it's in our best interest to account for them in our plan for the future, and treat them well.

It's also simply not feasible for people who don't live in metropolitan areas. Should we just leave rural folk to go back to the horse and buggy? What does Joe Blow in Wyoming do if he lives 2 miles from his nearest neighbor and 25 miles from town?

There's a giant class of people that will be left behind if we get rid of cars, and they're being continually ignored by the anti-car movement. The pro bike / anti-car people have a point, but they will have to address this problem if they want to reach their end goals.

LeftHandPath··on The Lone Developer Problem
If you have one developer, he or she will be the expert of that project. If you want a team of multiple developers, and it's infeasible to have any one of them be an expert of the entire system (let alone all of them), then the amount of planning and standardization needed increases quickly. The bigger the team is, the stricter the rules for style need to be, the better the documentation needs to be, etc.

I would expect the cleanest projects to be ones written by single developers because A) these projects will typically be simpler than the ones that require teams, by nature, and B) they will be undistracted / avoid the flaws of design by committee. Think cinema auteur vs. a Marvel or Disney film with an army of writers.

Go lang is a good example of identifying and addressing the problems that appear when your code is managed by a large team.

LeftHandPath··on Physically Demanding Work Tied to Male Fertility
Absolutely! I came out of a long period of depression / anxiety (triggered by a specific event, not just chemical imbalance) by starting to go for walks a few years ago. That turned into more and more intense hikes (doing 10-20 miles in a single day). The difference of being indoors and sedentary vs outdoors and active was night and day.

Recently moved into an apartment with a 24 hour gym and started doing basic strength training with weights as well - quickly learned that my body prefers that to cardio, and now I do 2-4 miles of walking a day and 20-40 minutes in the gym. It's amazing. Wish I'd been doing it for years.

I'll give that podcast a look

LeftHandPath··on Physically Demanding Work Tied to Male Fertility
Dang. That actually explains a lot about why I feel good when I feel good.

It's amazing that just doing what feels good and ignoring all advice - whether from online / media / friends - often leads to a better end result than studying up on everything. Can certainly land you in trouble too, but largely, the body's built-in feedback systems are better at telling me what I should do than the words other people create to explain how their body's feedback systems have worked.

LeftHandPath··on Throughout the rich world, the young are falling out of love with cars
I think another thing that's being missed is that, due to EPA regulations, cars aren't really all that sexy anymore. The Maserati MC20 is a V6. The C63 AMG is has dropped from its namesake 6.3-liter V8 already, and will soon be a small displacement twin-turbo i4. That's not very exciting.

This wouldn't be problematic if the replacement were better, but it's not. Try going on a long road trip in an electric car: depending on your origin and destination, it may or may not be possible. It will take a significant multiple of the time it would've taken in an ICE car.

It's no wonder today's youth aren't interested in anemic ICE cars - they aren't as cool or exciting as they used to be. And electric cars are only really viable/useful for the rich (with garages to charge them in) and/or those who live in densely populated areas where they don't have to drive very far... and those places usually have viable public alternatives that young people without families are happy to use instead.

LeftHandPath··on Introduction to FPGAs
Anything that would make a fun ASIC could be turned into an FPGA project. Something like Ben Eater's GPU project, which he did on a breadboard, could be implemented on them, or you could make a toy CPU with RISC-V, or create a softcore (faster than a software-simulated, slower than actual hardware) version of any number of older processors.

Edit: Link to Ben's GPU project: https://eater.net/vga

LeftHandPath··on The unequal treatment of demographic groups by ChatGPT/OpenAI content moderation
A recent update showed it's moving more towards the center, which gives me some hope that they're trying to make it more objective: https://davidrozado.substack.com/p/chatgpt
LeftHandPath··on Replacing a SQL analyst with 26 recursive GPT prompts
Still, while it might not be useful yet, can’t it stand its own as an intriguing proof of concept?

The first car was hardly ready to replace the horse. But look where we are now.

LeftHandPath··on Netflix has created a self-fulfilling cancelation loop with its new shows
It seems like part of a larger trend of overemphasis on min-maxing profits by praying at the altar of data and using what those gods return to try to cut all the right corners on the product. In the end, there are things that don't show up in the data that do affect consumption.
LeftHandPath··on Many companies aren’t prepared to replace underperforming CEOs
I once heard a joke that, in the right environment "If you know what you're doing and show a little enthusiasm, you'll wind up on 6 boards before you can turn around and realize what's happening".

It makes sense that certain types of people would wind up on a lot of boards very quickly.

LeftHandPath··on Elites tried to monopolize hunting
I would encourage you to read the current literature. The evidence is more compelling than you might expect. Actually Meltzer’s 2020 paper (linked in my previous comment) touches on this exact concern under the subheading, “Getting past the Impasse”. There was another good paper that broke down how the end of the Pleistocene was radically different from previous glacial transitions and how the effects of that likely played into the extinctions. Combined with the revelation that most mammoth “kill sites” were actually more likely to be scavenged… it’s not at all an unlikely picture.
LeftHandPath··on Elites tried to monopolize hunting
Small counter-point: The theory that the Clovis people hunted megafauna to extinction has been challenged a lot by recent research. It looks like North-American megafauna were actually quite likely driven extinct by changes to the climate. Analysis of the prevalence of fungal spores from large herbivore dung suggests that megafauna began going extinct in the northeastern parts of North America, and did so long before the Clovis people - who arrived from the west - would've been there to affect them.

Here's a very well-written article from 2020, from the respected D. Meltzer, that breaks down the evidence really concisely and cites most of the other literature I would point to: https://www.pnas.org/doi/10.1073/pnas.2015032117

All of that said, I agree with and want to add to your main point. We did see commercial hunting result in exactly the conditions you described in early American history. Actually, famous commercial hunters like Boone recognized that we were quickly losing the prevalence of wildlife (although it is likely that the prevalence was only there because of the recent demise of the majority of the Indian - and I use that word for the same reason as the author I'll cite - population that had been hunting them, see Charles Mann's "1491").

LeftHandPath··on Speculation that wormholes and entanglement are two aspects of the same thing
That is true and a much needed check. Thank you.
LeftHandPath··on Speculation that wormholes and entanglement are two aspects of the same thing
Hah... Maybe they've figured out that most of their readers are the same pseudo-intellectuals that will misunderstand things like Schrodinger's Cat and refer to it like magic, quietly hoping that other people will look up to them as all the wiser for having referenced it. Like a bartender I met a while ago that confessed to me that he and his wife interpreted quantum mechanics in a way that borders on religious, using it to discredit the concept of free will altogether.

> Take gravity, add quantum mechanics, stir. What do you get? Just maybe, a holographic cosmos.

Something tells me I'll be hearing a lot of confused misinterpretations of this over the next few days... A lot like the confusion over entanglement after this year's Nobel prize.

LeftHandPath··on Plastic might be making us obese
The difference between a nice brioche - made with plenty of sugar, with a soft, fluffy character - and a standard loaf of french bread is quite large. I spring for the french bread only because it's cheaper. Bread with sugar is superior.
LeftHandPath··on Random Google Street View
I spent the following hour and a half after clicking on this on that site. Wow.

Being able to "experience" other locations, even in that shallow of a way, is really, really amazing.

LeftHandPath··on Wikipedia Recent Changes Map
Probably for the best. After removing vandalism from the page of a prominent political figure (not a president, just someone who was the focus of the news), someone posted my approximate location to the discussion page and accused me of "sock-puppetry" (for removing an effort to link said official's views to a fictional cult from a major TV show). They also tried to use it as proof that someone from one of the big 2 US political parties was editing the page, since I was near the political party's headquarters.

Honestly I'm surprised Wikipedia hasn't had a case like Reddit's harassment of innocent people after the Boston Marathon Bombings, given how tribal and jingoistic the most-active editors are.

LeftHandPath··on What have we lost? – Demo of exotic OSes (2021) [video]
I've noticed a lot of the more experienced people in our office stop trusting things as soon as they see drop shadows and branded color schemes. And they are all very quick with the old terminals.
LeftHandPath··on What have we lost? – Demo of exotic OSes (2021) [video]
That's funny - I am currently working on a web app to GUI-ify the green screen for my company's IBM i OS on a similar Power8 system. They love the green screen but this was the easiest way to reduce the amount of manual entry we're doing for a specific 3rd party application we run on it.

A different tool I made ran in the PASE [1] environment on the same system -- compiling & running C++ in IBM's AIX runtime environment. Really interesting experience.

LeftHandPath··on Equality is prevented by the misperception that it harms advantaged groups
I had not seen that before, thank you for the link.
LeftHandPath··on Equality is prevented by the misperception that it harms advantaged groups
This seems to be the issue every time people bring up equality. The truth is that we are doing a lot better in terms of equality of opportunity than we give ourselves credit for. And equality of opportunity often produces disparate, unequal results - like in countries with better gender equality, where we see more unequal distributions of workers in different fields [0].

The dishonest argument that equality = equality of outcomes will harm us in the long run and push us towards unhealthy and draconian social policies.

LeftHandPath··on AMC Order Confirmation Pages Are Indexed by Google, Exposing Sensitive Info
Some of the pages load and show full details even when you open them in an incognito window.

Really hoping for a reply from AMC but I don't expect one.

I also wondered if they might be test pages of some sort but they look legitimate.

LeftHandPath··on AMC Order Confirmation Pages Are Indexed by Google, Exposing Sensitive Info
That could make sense. The pages don't always seem to be crawled

And I never would've found the bug if I didn't look it up to check if I understood the fee right!
LeftHandPath··on How to Walk (12 miles a day)
For the past year or so, I've walked between 1 and 6 miles a day at my local park (weather permitting). Putting headphones on never struck me as an idea, which is strange because I had them in basically constantly when I was wandering the UF campus all day a few years ago.

I enjoy listening to the animals / birds / insects, and tossing friendly hellos to the people walking by. (Actually, maybe that's why -- at the park where I walk, headphones would feel slightly antisocial)

LeftHandPath··on The Negative Link Between Extraversion and Perceived Listening
On several occasions I've found myself taken aback when someone asked me a deep/attentive question about myself. There are only a few people in my life that I actually care enough to hear their answers to those of questions, and I assume they are the same way.

Sometimes those people creep me out and sometimes it forms a lasting bond. But I fully understand what you mean when you say you perceive it as BS. It just sets off alarm bells and makes my brain pay way more attention to decide whether they are being genuine or not (and if they are, to find out why the apparent bond is so asymmetrical).

LeftHandPath··on Ask HN: What helped you get good at programming?
My first real experience programming was when I was 19, before ever having a class, teaching myself PHP/JS on the job to write custom wordpress themes. I started writing inefficient spaghetti code and progressed into writing object-oriented, then started looking at performance. The performance aspect was definitely the deepest rabbit hole.

I would say that I learned more doing that than I have getting a CS degree at my state school (aside from writing performant code, which classes have helped with). But it is mostly because I viewed getting good as a way to escape from some bad circumstances at the time - every word I didn't know was a low-hanging fruit waiting to be picked. I did a lot of reading, and I practiced at home in my spare time as well.

I got really good at front-end stuff and learned how to use the terminal so that I could host and manage our company's websites on a digital ocean droplet (running centos). I learned a lot on the linux terminal - writing bash / shell scripts, managing configurations, etc. Improved speed a lot by configuring apache... then again by redoing things in Nginx on the next site, which I've preferred since.

Since I've gone back to school, going overboard on programming labs has also helped a lot.
