hahajk··on What can LLMs never do?
Oh, I thought this was going to be a semi-rigorous discussion on computability. It's actually just another "GPT-4 still fails at these prompts" essay.
hahajk··on How to prevent Lyme disease this summer
I'm super concerned about the new longhorned tick that was recently found in eastern states. It can reproduce asexually and spreads fast. Scientists are still figuring out if it can transmit Lyme to humans (it can at least carry it).

A terrifying sentence: "It is common to find hundreds of ticks on one animal"

hahajk··on Biden signs TikTok bill into law, starting clock for ByteDance to divest
I didn't see the parent say there was no precedent.

But anyways, I like to hope that the US is better than China. If US citizens are abused while in China, I would be appalled to see Chinese citizens abused in the US as retribution.

hahajk··on My 25-year engineering career retrospective
On the other hand, I often do non-required things just because I'm curious and they have often been boons for my team. As an example, as a proj manager at a big org I went through the steps of setting up my own tenant account in our org's AWS system so I could play around with compute nodes. A year later they had issues with the team that managed the AWS environment and couldn't create new accounts for almost a year. As a result, no one in the org could bring on new contracts requiring cloud computing. Except my team: Our contractors could be added to my tenant account and continue work. This was a huge deal when we were trying to get a few experimental projects off the ground very quickly.

Almost all of my success has been a result of doing things no one else did because I was curious about them.

hahajk··on Children Need Neighborhoods Where They Can Walk and Bike
Everyone here is saying cul de sac suburbs do not give kids freedom, but they do for kids younger than 12. We moved to this "mc same" neighborhood when my daughter was 5 and she's been able to leave in the morning on her bike and be back by dinner, playing with friends around the neighborhood. Now that she's 8 she can take her 3 y.o. brother to the park down the street. If we lived in a denser, walkable neighborhood I wouldn't allow any of that to happen until she was in middle school. (the is east coast US for context)
hahajk··on The man who bought Pine Bluff, Arkansas (2022)
You could institute a UBI by building a tower that drops a $1 bill every minute.

hahajk··on Show HN: Free Plain-Text Bookmarking
Readwise has been really good for me to remind myself of highlights I made years ago. I set aside 30 minutes in the morning to go over a few highlights and write. I think that adding a "random bookmark" every day would be a good idea. Most of the time you say "huh, I forgot I had that" and forget it forever. But once in a while it comes at the perfect time. (Or a few days before/after the perfect time would still be nice)
hahajk··on The baffling intelligence of a single cell: The story of E. coli chemotaxis
Measuring student outcomes is hard!

For example, do you think we should encourage students to study for tests, or should we encourage them to just show up? After all, if you understand it intuitively why would you need to study the night before?

Also, the act of testing changes the students being measured. As does the existence of a test in the future.

hahajk··on Google Scholar PDF Reader
Readwise Reader has a nice pdf reader with highlighting, notes, and an AI reader tool. I organize sources using tags. It's very new and in active development. Academic research is not it's main focus, though, so it probably won't add mindblowing academic tools. (like citation support/ backlinks. although it does have internet backlinks that tell you want articles link to the one you're reading)
hahajk··on Brain waves appear to wash out waste during sleep in mice
Is the idea that yoga/meditation are more efficient than sleep at redistributing the cerebral fluid? That would be very surprising.
hahajk··on Ratchets over Levers
The part at the beginning about how critical software is to our world reminds me of the time (or so I've heard, it was before my time) when there was a push to make software engineering a licensed field. A "real" engineering. I'm very happy that didn't happen.
hahajk··on The Xylophone Maze: Screen-free coding for children
I wonder if it's because the average parent is not a very sophisticated bureaucrat. We get tired and just say yes because we need to survive. As children get older and interface with more institutions that have teams of people to tell you no (or no process to even ask), we enter a learned helplessness: a no today is almost certainly a no tomorrow.
hahajk··on Macaroons Escalated Quickly
Wow, thank you. That was a real broccoli = kale moment for me.
hahajk··on Give AI curiosity, and it will watch TV forever (2018)
The researchers quoted were explicit about this:

> OpenAI researcher Harri Edwards tells Quartz that the idea for letting the AI agent flip through channels came from a thought experiment called the noisy-TV problem. The static on a TV is immensely random, so a curious AI agent could never truly predict what would happen next, and get drawn into watching the TV forever. In the real world, you could think of it as something completely random, like the way light shimmers off a waterfall.

The headline is really just inappropriate anthropomorphization.

hahajk··on Driverless cars immune from traffic tickets in California under current laws
I still believe the free market can work for self driving cars. If there's demand for offline self driving cars, someone will make them. Probably someone in Asia will make them affordable.

But I believe regulatory capture and anti-competitive tariffs are likely to make affordable, buy-and-use cars impossible to sell in the US. Regulations will likely change annually, like they do for cars right now. The govt will be worried that China has control of our morning commute.

I hate being cynical, but cars do seem like a lost cause.

hahajk··on Things are about to get worse for generative AI
> And a whole universe of potential trademark infringements with this single two-word prompt: animated toys

If you flood the market and dominate children's culture with toys from your TV shows, you absolutely cannot complain when your toys are considered iconic enough to be the generic "animated toy". These images don't replace or substitute the things they are depicting.

hahajk··on Veritasium: The SAT Question Everyone Got Wrong [video]
I can't think of a situation in which "or" would ever be used in an exclusive sense unless it was explicitly called out as an XOR or included "but not both".
hahajk··on 2023: A year of groundbreaking advances in AI and computing
I believe Google Maps invented AJAX. Google Docs I think was actually acquired, but it was definitely ahead of its time.
hahajk··on Why Life Does Not Really Exist (2013)
But morality only concerns itself a certain complex class of organisms, right? We don't weep for loss of innocent life we inflict when we take antibiotics.
hahajk··on Evernote will restrict free users to 50 notes starting December 4
It would be easy to point to their recent acquisition by Bending Spoons and say that they're squeezing the stone for blood.
hahajk··on Stanisław Lem's vision of artificial life
I heard Vint Cerf describe the original AI algorithms as basically "heuristic algorithms". "AI" was used to described a class of algorithms that only worked some of the time as opposed to the mathematically proven algorithms.
hahajk··on The Bond villain compliance strategy
Perhaps because of individual sovereignty, which I believe is the basis of our rights in liberal democracy.

We have given up some of that sovereignty in order to live in a govt. We should ask if giving up the right to free exchange is necessary for the functioning of our society.

hahajk··on Zelle finally caves after years of refusing to refund scam victims
Wait, how so? Didn't most transactions take place in cash for most of history? Cash isn't reversible.
hahajk··on Your online order has been delivered and it’s teeny tiny
So, what's the story here? People don't read the listings close enough and accidentally buy miniature items? All the examples listed had accurate dimensions in the listings and didn't seem deceptive. They were also useful items if, for example, you do want to hang up very small clothes which some people do.
hahajk··on A shortage of teachers for computer science classes in California
> Computer science has evolved to include more than basic coding. A good class now includes lessons on artificial intelligence, media literacy, data science, ethics and biased algorithms, so “students know how to think critically to solve problems using technology,” Flapan said.

I can't imagine any students walking away from such a class retaining anything about any one of those subjects after the final exam.

hahajk··on My rude-ass car
How much of this is trying to get a higher IIHS safety rating[1]? I liken these features to the idle engine auto-off feature that allows manufacturers to add 1 or 2 city mpgs to their rating even though I've never known a human who likes that feature.

hahajk··on Quindar Tones
I didn't know what a Capsule Communicator was, I thought it was a piece of equipment used by astronauts in their space capsule. But it's a role if the ground crew; the person who is responsible for communicating with the astronauts.

Knowing that, the article makes more sense. Mission control has to send audio to transmit and also turn the transmitters on and off. They do that all in one data line (phone line) using these tones.

hahajk··on Detroit wants to be the first big American city to tax land value
Does she not already pay property tax on her home? And sales tax on her purchases?
hahajk··on Jesus nut
Bell 206s, still used today, have retaining bolts. And while I don't know what the engineers call things, pilots certainly do call them Jesus nuts.
hahajk··on Bing ChatGPT image jailbreak
Also to be fair, Notepad was exploited to execute arbitrary code.
