jryb··on Eza: A modern, maintained replacement for ls
I don't know how common my situation is, but I don't have any of those constraints. I have eza aliased to ls both on my daily driver and all of my work servers and it hasn't caused me a single problem.
jryb··on Entering text in the terminal is complicated
Maybe try fish? Tab completion will suggest subcommands, and if you type - or -- and hit tab, it will suggest the available options with help text generated from man pages (example: https://flaviocopes.com/images/fish-shell/autocomplete.png). Doesn't really help with positional arguments but it's definitely enhanced the discoverability of many tools for me.
jryb··on Ask HN: How has AI changed your learning methods?
For scheduling, I just guessed at the weights - the interval to the next review just increases geometrically at a different rate for each difficulty rating. I'll probably run into ease hell issues but it hasn't happened yet. I tuned the weights by intuition over the course of a few days until I arrived at something similar to what I had in Anki.

Mobile support was a concern of mine as well but I just took the easy way out and make a simple SPA in javascript and futzed with the CSS until it looked good on my phone (also mostly ChatGPT). One explicit design principle was that I will never support anyone but myself, which simplified things greatly. The SPA interacts with a little CRUD app that uses a sqlite database to store my cards and activity.

jryb··on Ask HN: How has AI changed your learning methods?
Yes, it's an anki replacement. I found adding/modifying cards programmatically was a nightmare. I also wanted to add new features, like having ephemeral cards that disappear after a few reviews (the use case was translation of chatgpt-generated sentences - knowing myself I'd just unconsciously memorize the answer and not actually go through the task of translation so I wanted to automatically get rid of those cards after they outlived their useful lifespan). And in general I didn't want to be constrained by someone else's software.
jryb··on Ask HN: How has AI changed your learning methods?
It's the first thing I go to when I have a "stupid" question. I also just use it to learn languages and math, and get clarification when something in my area of expertise is confusing. It's dramatically reduced my search engine use. It also enabled me to write an anki clone that I just wouldn't have bothered with otherwise.

That said, it is actively harmful when discussing components of Chinese characters - it hallucinates so much it's essentially unusable. I stick to traditional resources for that. I'm also reading as many scientific papers as before, there's really no substitute for that yet, and I haven't found it very good at literature searches.

jryb··on Top FDA official overrules staff to approve gene therapy that failed trial
There appears to be a new phenomenon where patient advocacy groups are able to pressure the FDA into approving medications for conditions with no existing treatment (I found out about this when reading the fact sheet that came with a medication that kept stating it had no statistically significant effect for the thing it had been prescribed for - as to why my doctor even prescribed it is another story). The people providing this pressure are either stock puppets or just desperate for hope, but either way the fact that the FDA will ever cave like this is horrendous.
jryb··on All the Data on Earth Can Fit in a Cup of DNA in MIT's Jurassic Park Project
Sure, but existing protein sequencing and synthesis technologies are severely limited. You'd lose so many orders of magnitude in scale, speed and cost that the increase in the number of characters wouldn't be worth it.
jryb··on Ask HN: How can I sleep more and deeper?
You could easily have sleep apnea.

You didn't mention caffeine, but the half life of caffeine can be over 12 hours. Even if you limit yourself to two cups of coffee at 8 am, you'd still have as much caffeine in you as if you had one cup of coffee at 8pm. The rule of thumb about "no caffeine after noon" is just unreasonable, it really should be "almost no caffeine".

jryb··on Ask HN: Why is nobody manufacturing low tech electric cars in 2024?
While political identity certainly plays some role, a BEV is still a major purchase and people will take other factors into account. Is it really inconceivable that someone would want a car like the ones they're used to, except with a different power source?

Every time I look at electric cars there's always some insane choice, e.g. the brake lights don't turn on when regenerative braking is active, even though your car is rapidly decelerating. The touch screens are also a safety concern - you can't change the music or skip ahead on a podcast without taking your eyes off the road for a meaningful amount of time. The fact that you're paying well over the median price for a new car makes it even less appealing.

FWIW I don't own a car and I'm not in a hurry to get one.

jryb··on LSP-AI: open-source language server serving as back end for AI code assistance
neovim allows multiple LSPs. In my setup the different sources show virtual text comments with unique colors for each lsp, one message after the other - I think this is default behavior but i'm not sure
jryb··on Most to least common 4-digit PIN numbers from an analysis of 3.4M
Even at 8 digits people could still use their birthdays. I think there's a tradeoff between PIN size and fraction of the population that will feel comfortable picking a number with no significance. I'd speculate that in a world where every PIN has to be 16 digits that almost everyone would just use 2 or 4 concatenated dates.
jryb··on ESpeak-ng: speech synthesizer with more than one hundred languages and accents
When speaking Chinese, it says the tone number in English after each character. So "你好" is pronounced "ni three hao three". Am I using this wrong? I'm running `espeak-ng -v cmn "你好"`.

If this is just how it is, the "more than one hundred languages" claim is a bit suspect.

jryb··on China's Population Could Shrink to Half by 2100
There's nothing outrageous about predicting that a country with a very low fertility rate will experience population decline over time. The point of these predictions is to consider the consequences of maintaining current policies.
jryb··on Principles for Keyboard Layouts (2022)
At least for any defined set of layouts, you could infer what those other keypresses would be and compare their efficiencies. Still a compromise but it satisfies all the security issues.
jryb··on Principles for Keyboard Layouts (2022)
You don't need a keylogger. Just take some things you've written and count the characters. It won't be exact since it excludes rewrites but the distribution should be very close.
jryb··on Ask HN: How to stay up to date with advances in Alzheimer's research?
Google Scholar really can't be beat. When you find a good review, start following authors of the references that look legit. You can also have alerts for new papers with keywords in the title or other sections.

inciteful.xyz is also really great at finding the important papers for a subject. As you add more papers the recommendations get better.

jryb··on Ask HN: What is the most useless project you have worked on?
Is using a host that doesn't do this not a possibility?
jryb··on Dali owner file petition to cap liability in Baltimore bridge collapse at $43.7M
The engine failing isn't some random, unlucky event. Regular maintenance and inspection should prevent this. Whenever this happens to an airplane it's considered negligence - there's no reason why we shouldn't have the same standards for ships.
jryb··on 'Vaccine lettuce' bill (food containing a vaccine is a drug) passes in Tennessee
There are two reasons I can think of why that wouldn't happen: first, there's no primer to even initiate the reverse transcription. Maybe you might get unlucky and there's something close enough floating around. But integration machinery usually requires some specific sequence to identify the ends of the viral genome. Maybe that exists, it's not my field, but I've never heard of one.

Also, even if it did integrate, there would be no promoter, so the vaccine gene wouldn't get expressed. So the only danger I see would be if it integrated into something functional, but the virus was going to do that anyway. But this is so improbable to begin with I wouldn't worry about it.

jryb··on Buyers Are Avoiding Teslas Because Elon Musk Has Become So Toxic
What the article doesn't address is why there's no compensating effect from the people who like his antics. The two groups might be of vastly different sizes of course, but assuming this one survey from a single consultancy can be taken at face value, it would make me more skeptical that the views he's been espousing could make american conservatives comfortable buying electric cars without sacrificing even more business from liberals (which someone was arguing on here once).
jryb··on Analysis of Competing Hypotheses
Maybe I'm missing something but this looks like a rebranded scientific method.
jryb··on HIV in cell culture can be completely eliminated using CRISPR-Cas gene editing [pdf]
Your point is broadly correct (not sure about disability though), but I think it overstates the danger of what will happen in practice. Yes, if you picked a random target and blasted away, you probably wouldn't have a good time. But anything that even approaches clinical trials is going to get substantial engineering put into it to minimize (and characterize) all of the off-target loci. If there's meaningful editing near an oncogene then that's going to be a deal breaker for a particular guide. When the FDA was discussing the Casgevy application, they went into remarkable detail of how Vertex had measured the off-targets - the regulators really, really don't want to approve anything risky.

Frankly just getting it to work at all is the real hurdle in this case.

jryb··on Earth Received a Message Laser-Beamed from 10M Miles Away in NASA Test
Easy fix: subspace-based sensors. If the other ship is transmitting in any way, or its engine produces visible artifacts in the subspace field, it could be detected.
jryb··on Scientists get closer to solving chemical puzzle of the origin of life
Yes, there was this recent paper: https://www.nature.com/articles/s41586-022-04676-3

They essentially propose that RNA molecules would be ligated to a small number of amino acids and would then use them for catalysis, and from there evolved the ability to create proteins that are not covalently bound to RNA. So this bridges the RNA world with the RNA-peptide world, and from there it's much easier to conceive of how we arrived at modern biology.

There's a good reason to think that this was the path, since in all organisms today, tRNAs are ligated to single amino acids during translation.

jryb··on Ask HN: Who is still programming directly on a server?
You've misunderstood the "right" way's purpose. It's right because it solves a problem in a particular context, not because it's the best way in all contexts. You're not coordinating with other humans, so why have a mechanism to coordinate your efforts on a personal project? You're not risking people's incomes with minor downtime, so why build a resilient system? The right way comes at a cost of time and effort - why pay for things you don't want?
jryb··on What do you expect from personal blogs?
This is like asking if your band needs a horn section. Depends on the genre. Just make the songs you wish existed.
jryb··on Ask HN: Is ChatGPT becoming useless for many tasks?
It's hit and miss but the responses i get are all super detailed and usually quite helpful. I've never had interactions like yours. I'm mostly coding in Python with some Rust fwiw
jryb··on A vision for the alleviation of water scarcity in the US Southwest
But where are you getting that pure seawater from? If it's anywhere near the outlet, there's a scale at which the concentrated brine will affect the salinity of your inlet.
jryb··on My New Apartment's Most Aggravating Feature
When I was apartment hunting, I asked about this at a place that had smart locks, and they said I just had to fill out a "Reasonable Modification" form (or something to that effect) and they'd install a traditional lock.
jryb··on Ask HN: Is it impossible to use Kagi as default search engine on iOS?
It also works fine for me, I've been using it for a few months now without incident, on iOS 17 currently.
