jessetemp··on Ask HN: What is the purpose of all these AI spam comments?
I always wonder how much of HN is just bots debating bots
jessetemp··on Performance hacks for faster Python code
I didn't find 2 surprising either, but I'm a little surprised you never see it. If you want to treat the args to a function as immutable, what can you do besides copy, modify, and return a new object?
jessetemp··on Game design is simple
I hadn't heard of the author before this. I'll definitely read more of their stuff, but I thought the bottom line for part three was a little incomplete.

> Bottom line: the more uncertainty, indeterminacy, ambiguity in your game, the more depth it will have.

Sure, starting from 0%, adding uncertainty adds depth. But the player needs to maintain some influence over that uncertainty. If you crank the uncertainty up too 100% then its pure random which isn't deep or fun.

I've noticed a similar more-is-better trend in a few sequels I've played, where the first game had say 5 mechanics which were fun. Then the sequel has 10 mechanics, and because 10 is more than 5 it therefore must be more fun. But it ends up being too much shit to juggle and less fun as a result.

More isn't always better

jessetemp··on Everything You See Is from 15 Seconds in the Past, Research Suggests
The title contradicts the article. Our eyes are averaging information that is up to 15 seconds old, but we can obviously react to visual stimuli in less than 15 seconds so it’s not all that old. They’re probably also confounding the research by using faces as the thing that changes over time, since our brains are sort of hardwired to respond to faces differently than other stuff
jessetemp··on Ecologists horrified as nature reserves emptied of insects
Meanwhile the local “eco friendly” pesticide company is knocking on everyone’s door, showing them pictures of scary looking bugs, offering to treat their entire yard from the foundation to the pavement. I don’t get it
jessetemp··on Ask HN: Any US based PCB makers?
OSH Park is pretty great for prototyping. $5-20 / square inch depending on the board type. I remember running into some constraint limits years ago but they may have improved since then.

jessetemp··on US honeybee deaths hit record high as scientists scramble to find main cause
Flies are pollinators in the US too, but the second to last paragraph is a little worrisome

> Another important point is that we have very good evidence of range declines and even extinctions among wild pollinators, which aren’t being managed by anyone.

jessetemp··on Phased Array Microphone (2023)
What were the results of your study? I’ve heard that bat lungs are so sensitive that when they fly across the pressure differential of large turbines their capillaries basically explode
jessetemp··on Illegally logged wood from Cambodia likely ending up in U.S. homes
> E.g. what if the liability was solely with the person who sold me the wood (even if they’re actually “innocent” and simply bought from a fraudulent distributor).

Why would the liability stop with them and not you? If only the last person in the chain is liable, the shouldn’t it be you who is sued by the people whose land was exploited for lumber?

jessetemp··on External RF-EMF Alters Cell Number and Reactive Oxygen Species Balance
This is about mid range wireless charging [1] not Qi chargers. If something is charging your watch from across the room it's blasting your whole body.

The FCC limits RF exposure to 1.6 W/kg. [2] That's presumably the standard the authors argue is insufficient to prevent ~7MHz wireless chargers from inhibiting cell apoptosis.

jessetemp··on Hints of a Hidden Structure Detected at the Edge of the Solar System
Structure, as in pattern, not space station
jessetemp··on Do quests, not goals
I think what’s going on behind the verbal sleight of hand here, is focusing on the process (quest) instead of the outcome (goal). It’s the difference between doing a thing and having done a thing. I might enjoy having written a book, but I don’t think I would enjoy writing a book. And I don’t think calling it a quest instead of a goal would make much difference
jessetemp··on Ask HN: What is the best way to author blogs in 2024?
I don't want to cramp your style, but displaying those in a table would really improve readability
jessetemp··on Sleep deprivation disrupts memory
I’ve had the same problem. In my case it was uBlock hiding the full page cookie dialog but the dialog was still disabling text selection. I really wish websites would just respectfully set the minimum by default and let users opt in to the extra tracking. Then reward those users with internet points or something. People go nuts for internet points.

Regarding the article itself… I always wonder (while laying awake at night) what impact trains have on people’s mental health. I’m thankfully not close enough to get woken up by them, but they roll through at like 1am, horns blaring at every hint of an intersection. It’s gotta be measurably unhealthy for people living near the tracks

jessetemp··on Underscores are stupid? Get a Japanese keyboard (2012)
Sounds like a questionable tradeoff to me. I just want underscore remapped to shift-space. It’d be easy to type because they’re both big keys. And underscore is a variation of a space anyway. It’s like an uppercase space
jessetemp··on History of the Paper Clip (2016)
It’s wild how many patents were granted for basically the same thing. Add a little wiggle on the end? New patent!
jessetemp··on Today's AI Isn't Sentient
Exactly. LLMs are closer to a plinko game than consciousness. And I'd bet they quickly start returning gibberish when you run them in a feedback loop, sort of like an opamp going to a power rail in a badly designed circuit
jessetemp··on British engineering giant Arup revealed as $25M deepfake scam victim
Not that it changes your point much, but AI research also took decades. It’s just that the last few years are when all these milestones were achieved
jessetemp··on Fastest rate of natural carbon dioxide rise over the last 50k years
They’re probably referring to the earth getting enveloped by the sun in a billion or so years as it expands.

I still think you’re right though. The better plan is staying on earth. The trick is moving it outward as the habitable zone expands with the sun. Only have to convince humanity to sling a giant meteor just outside earth’s orbit every year for millions of years without messing up. What could go wrong?

jessetemp··on Sir, there's a cat in your mirror dimension
That post just gets better all the way through.

I can't believe I never realized the frequency domain can be used for image compression. It's so obvious after seeing it. Is that how most image compression algorithms work? Just wipe out the quieter parts of the frequency domain?

jessetemp··on Can turning office towers into apartments save downtowns?
That’s an interesting idea. If there’s enough room between floors already, I wonder if you could squeeze in some horizontal periscope skylights without removing floors. Just need to occasionally send someone out to scrub the exterior window like in that show Silo
jessetemp··on A useful productivity measure?
They're saying the things that don't add value are muda (waste), not the foundational stuff. I only know that because my employer uses the same jargon. And since almost no one speaks phonetically-spelled-out Japanese, they always follow it with (waste) in parentheses
jessetemp··on Drug resistant bacteria found on ISS mutating to become functionally distinct
How do you genetically engineer a resistance to fluid in the lungs, or radiation exposure, or whatever all the other interesting ways to die in space are?

Imagine all the suffering caused by failed attempts, people living their whole life with bad lungs so a privileged few can get a little closer to their space fantasy. I wouldn't want to be born into that experiment

jessetemp··on Stack Overflow and OpenAI are partnering
Might very well be in panic mode. They're also partnering with Indeed to bring back a new version of StackOverflow Jobs.

jessetemp··on Spotify getting into enterprise IT tools
Well to me, sensible would be where I can play an album, and then select a couple more albums to start playing in sequence after the first album.

Spotify's queue doesn't do that, at least on windows. Instead, playing the first album adds it to a queue but not the queue. Selecting more albums inserts them after the current track, not after the album. If I decide I want to remove the remaining tracks of the first album from the ghost queue and only listen to the queue I have to remove them one by one. And the most bonkers part, is when removing the last remaining track from the first album's ghost queue, Spotify replaces it with a different track from the first album! There's no way to remove the ghost queue.

The workaround is to simply not use the play button and only add albums to the queue by clicking into the ellipsis menu, but it's a bit of a kludge and not what I'd call sensible. Plus for some reason I always go for the green play button first, then decide later that I want to add a few more albums to the queue

jessetemp··on Charlie Munger: Turning $2M Into $2T
It's not perfect, but pretty close if you compound monthly. It works with your examples too.

100% interest (compounded monthly) doubles at about 0.75 years, and 0.75 interest doubles at around 100 years.

41% interest doubles at around 1.75 years, and 1.75 interest doubles at around 41 years

jessetemp··on Books for Game Developers
Circa 90s and early 2000s.

I like how there's a whole book on quaternions. I've never understood them and I'm convinced every definition I've read was written by someone who also didn't understand them. I might try to find a copy if I ever dabble in 3d again

Edit: To clarify, I understand the need for quaternions (to avoid gimbal lock), just not how to use them manually. Euler angles are simple enough, I can change whichever axis by some degrees or radians. But with quaternions I never understood what was going on under the hood

jessetemp··on Google contractors vote to unionize in historic landslide election
Not disagreeing with the general complacency of humans, but the frog thing is a myth. They only stay in the water if you remove their brain

jessetemp··on Apartment rents fall as new supply hits market
> not sure why people keep beating the "if you add more supply, the price goes down" drum

The cynic in me assumes it's because they're investing in real estate and want more real estate to invest in, so they can continue profiting off the backs of people who just need a place to live

jessetemp··on Ask HN: Non-violent video games with great stories?
Lightmatter is a great first person puzzler that I haven't seen anyone here mention. The story is good enough, and if I remember correctly, told through audio recordings you pick up along the way. Non-violent, but you can die. I really liked the art style

Creature in the Well is a pretty fun adventure/breakout/pinball game. Light story. There is some conflict, but it's about as violent as pinball

Probably not for the kiddos, but Little Nightmares is great. The story is entirely told through ambience, which is dark and creepy. A sequel came out recently, but I haven't played it
