ahelwer··on Pre-seed, seed startups with employees in office have higher revenue growth
Yeah, it is even possible to do this sort of analysis in domains with exponentially-distributed outcomes?
ahelwer··on The $20 an hour Cessna 172 experiment (2020)
This is exactly how it is in the rock climbing community. People still die, including very experienced people. You only need to mess up a rappel weight transfer once, but you have to execute it successfully thousands of times over the course of your life. People cope by saying they're careful and it's the irresponsible people who die. It isn't true. No reasonable safety system can rely on you acting perfectly every time. A low-probability-lethal-failure activity that you many many times can get you eventually, no matter how careful you are.

I don't say all this to disparage GA, or rock climbing. I rock climb and intend to do so well into the future. But saying these sorts of things mean you aren't treating your hobby with the seriousness it deserves imo. It could happen to you; thinking otherwise is self-deception.

ahelwer··on The $20 an hour Cessna 172 experiment (2020)
Okay, is unleaded avgas mandated? Is it dramatically more expensive than leaded? For how long should I look up and see a GA aircraft knowing it's some rich idiot spraying my neighborhood with lead?
ahelwer··on Two C++ bugs I found
std::string wasn't included in the hardcoded emscripten imports, as I said.

The point of the blog post is that even though things are working as they are supposed to, it is easy to write weird bugs. I hope we can at least agree that making the undefined behavior of calling pop_back() on an empty vector to have that vector contain the entire memory of computer is an absurd choice.

ahelwer··on When Truman Capote’s lies caught up with him
This is true of basically all literary journalism. How do so many interesting things happen to these people that they can write about it? Easy, they make it up. David Foster Wallace is another example, said as someone who enjoys his essays. And David Sedaris, not that he really styles himself as a journalist.
ahelwer··on Official Warning: Zero3K
Starting a crusade against anime pfps (one of the most ubiquitous styles on the entire internet) after you watched a youtube expose of an evil online forum is not a reasonable thing to do.
ahelwer··on Official Warning: Zero3K
"I saw some random crap on the internet so now other people have to start behaving in a certain way" is certainly one of many possible ways to navigate the world.
ahelwer··on Ask HN: How do you trust that your personal machine is not compromised?
I bought a Turris Omnia used on ebay for about a hundred bucks. Very powerful, open source hardware & software, good community, adblock server built in if you're too lazy to set up a pihole, enough compute power to host lots of neat services on it.
ahelwer··on Writing a TLA⁺ tree-sitter grammar: my foray into free software
Not an emacs person myself (yet!) - Carl Thuringer created tla-mode that apparently uses the grammar: https://github.com/carlthuringer/tla-mode

Haven't tested it out myself. Happy to take any PRs if emacs needs its own set of query files; they would live in https://github.com/tlaplus-community/tree-sitter-tlaplus/tre... and they can be added to CI runs to ensure they stay in sync with changes to the parser.

ahelwer··on I measured the pollution from my gas stove
How much did you pay for the meter? Last time I looked into this measurements for various metrics were basically useless (unless you're only looking at relative, not absolute numbers) unless you spent at least a few hundred bucks and occasionally calibrated it.
ahelwer··on Summary: “No: The Only Negotiating System You Need for Work and Home” – Jim Camp
I wonder about the longest stretch of silence that has passed in a negotiation because both parties read the same negotiating self-help books and attempted to apply them on one another.
ahelwer··on Ask HN: Why haven't bookmarks been re-invented?
I don't know about anyone else, but "giant list of media to consume in the future" be they games, movies, books, or blog posts is antithetical to me actually eventually enjoying that media. The value of having a list of things that I thought might be interesting but not interesting enough to read immediately is basically zero.
ahelwer··on Government should incentivize high performance home builders
I don't know why you think we can possibly come up with a competitor to something that, left alone for 20 years, builds itself into an incredibly strong & versatile building material, while sequestering carbon, using what amounts to crazy self-replicating nanotechnology from several hundred years in the future.
ahelwer··on Twitter suspends pg's account [fixed]
So go to a different instance or even start up your own! That's the beauty of it, now you don't have to care what person C thinks - you can just go elsewhere.
ahelwer··on Tesla FSD data is getting worse, according to beta tester self-reports
You've given no actual reasons you find this hard to believe, just running on 100% vibes. The data reported to regulators doesn't lie. Tesla really is that far behind the competition.
ahelwer··on UC Berkeley launches SkyPilot to help navigate soaring cloud costs
Per a recruiting email I received last year, I believe anti-cloud computing is called "fog computing".
ahelwer··on Not-so-great features coming soon to Windows 11
Get an AMD graphics card and use wayland.
ahelwer··on Remote work is gutting downtowns
Yep. I went from being sick roughly one week out of every 1-2 months before covid to only getting sick maybe once a year now that I mask in public places, thoroughly wash my hands with soap every time I arrive somewhere, and occasionally wash my phone. Never going back. This whole "train your immune system" thing is BS. Hygiene is important!
ahelwer··on When McKinsey comes to town
There are plenty of non-old-white-boys at McKinsey doing heinous stuff. I wish fixing things was as simple as increasing diversity, I really really do. Improving diversity is laudable goal in itself; don't count on it to fix these sorts of problems.
ahelwer··on AI Homework
Well thankfully I haven't been in school for over a decade at this point, so rarely (never?) encounter these hard-cutoff no-second-chances trivia situations. I operate in the real world, where continually making something that's not-quite-correct then refining it and fixing the errors is how basically everything is accomplished.
ahelwer··on AI Homework
Pop history generally is so far from accurate that I don't think you really have much to worry about. Nearly 100% of fun historical facts upvoted to the front page of reddit are basically incorrect, for example.
ahelwer··on AI Homework
I could easily imagine an ordinary person giving this exact same wrong answer (confusing Hobbes and Locke) - we're talking about value-over-replacement here!

In the process of learning things we take in wrong information all the time. A lot of it is even intentionally wrong, in the sense of being simplified. These are rarely large obstacles to true understanding. Sometimes they're even beneficial, as correcting prior beliefs can drive home the more accurate belief with greater force.

ahelwer··on AI Homework
I finally went ahead and tried ChatGPT this morning (along with everyone else seemingly - it is now heavily rate-limited!) and I am truly blown away. I ask questions about various things (in my case, embedded systems development on the PineNote) and it gives the same quality of answers I would expect from a median coworker. Sure they're maybe not 100% correct, but most coworker answers aren't 100% correct either. They're at least in the right ballpark, and very rarely do we achieve detailed of knowledge of something from a single source - it's all about taking in info from various places and integrating them (conflicts and all) to derive a more-and-more-detailed grasp of the things we're learning about. The ability to ask questions about a specific thing (example: What are waveform files for e-ink screens? Followup: Is it possible to damage e-ink screens by modifying wave form files?) very quickly without having to sift through mountains of blogs and random Q/A websites and documentation and textbooks for the answer is incredibly useful.
ahelwer··on The Great Pi Zero Showdown
I don't see why people are so attached to the pi when much more capable computers - 2013/14 era used Intel NUCs or Mac Minis - are available for a hundred bucks on ebay. Maybe lots of people are using the pi for low-power-draw projects but if people are running a pihole and other services on them you might as well go for the other option.

There's also the QUARTZ64 boards from Pine64 which are definitely available and include fun things like a neural processor: https://pine64.com/product-category/quartz64/

ahelwer··on The U.S. military is poisoning Okinawa
A specific landfill project to... what?

> The referendum asked whether voters approved or opposed the landfill work at Henoko Bay for the construction of a new United States Marine Corps base.

Can you explain how this is dishonest?

ahelwer··on Ask HN: Do you feel bad when devices aren't utilized to the extreme?
There is such a staggering quantity of electronics (or just stuff, generally) wasted that if you're putting something to literally any use at all - like your ipad clock - then you're miles better than standard.

I also encourage everyone to be aggressive in putting things on the used market, or even giving it away for free (commonly in those local facebook "buy nothing" groups). For a lot of mass-produced things you can view the used market as a storage space. Sell/give it away one year, and if you need it the next year you'll probably be able to find someone else doing the same. On the flip side, avoid buying new stuff. Try to only buy used electronics, especially.

ahelwer··on 'Nobody Wants to Work Anymore' Meme Cites Real Newspaper Articles
It is just fundamentally strange that you are including gig economy work in a discussion of automation. That isn't automation! The people shopping for you are not automatons just because your interaction with them is mediated by an app! They are doing your chores for you and have less time with their families so you can have more time with yours.
ahelwer··on Show HN: Google Fonts Checker
If you're hosting your website with a static site generator on github/gitlab/sourcehut etc., check the documentation for whatever theme you're using. I'm using the Beautiful Hugo theme and switching to self-hosted fonts (and javascript) was as easy as adding

  [Params]
    selfHosted = true
in the top-level config.toml.
ahelwer··on FreeTube – A Private YouTube Client
This sounds plausible enough until you examine it and realize you're turning viewing ads into some kind of moral duty.

"Have you witnessed the requisite quantity of behavior-modifying media today, Citizen? Remember, we all have to do our part. I see you only internalized five minutes' worth yesterday. This is below target. Your beliefs and desires have not been sufficiently altered to meet corporate goals. We require greater acquiescence."

If a company wants to paywall something then they can do that. Maybe I'll pay for it. Advertising shits in your head. I don't accept the modification of my mind as an acceptable form of payment.

"So don't use it"

No. What are you going to do about it? Tell me I'm immoral?

ahelwer··on Anti-War Speech Sent Eugene V. Debs to Prison, 1918
It was a whole lot of motivated speculation about how some people were thinking hundreds of years ago and how they would interpret contemporary weapons. It is indistinguishable from a reddit post with fancier words. Scalia would have been happy to hear you think it's a fantastic piece of legal scholarship, though - it was his job to dress up his opinions in that way. I quite enjoyed this account of it: https://www.fivefourpod.com/episodes/dc-v-heller/
