jareklupinski··on Ping-pong robot beats top-level human players
robot ping pong league
jareklupinski··on Stephen's Sausage Roll remains one of the most influential puzzle games
> I find it very tedious to move blocks around manually, especially if I already know the solution and I'm just making it happen

thinking about how calvin's dad would explain every video game is either sokoban, or chess

jareklupinski··on San Diego rents declined following surge in supply
you're not the one with stuff to reconcile

simply ask the people on the vested side: "why do you want rents to stay high?" and stand back

jareklupinski··on A Pascal's Wager for AI Doomers
playing dead might work for some species, but idk if i want humanity's "finest hour" to be spent pretending to not be worth taking over
jareklupinski··on New unsealed records reveal Amazon's price-fixing tactics, California AG claims
correct, amazon's policies made it impossible for local stores to offer a deal, making sure you pay the 2-3x inflated sum no matter where you go, instead of what the real cost would be if fair competition were allowed
jareklupinski··on New unsealed records reveal Amazon's price-fixing tactics, California AG claims
exactly, and as a result you ended up paying 2-3x more for all those tools than if other businesses were allowed to compete normally
jareklupinski··on Sequencing DNA at Home Locally on a DGX Spark and Mac Studio
> Your genome is the most private data you will ever have. You probably shouldn’t let it leave your house.

im probably going to publish mine

you can already grab it by following me for a day and picking up a stray hair?

jareklupinski··on The big business of survival bunkers
like the bunkers :)
jareklupinski··on Claude Code Opus 4.7 keeps checking on malware
> Who the hell does this system think he is to limit me?

presumably you paid money to another person who lent you the ability to use their API for _their_ purposes (likely: making money)

in an environment where "money-seeking" is the default behavior, it is only natural they're stopping you from doing things that will make them less money

think back to your computer club; was it about money?

leave to Caeser what is Caesers, or something

jareklupinski··on The Death of Character in Game Console Interfaces
> Do you hide the adult's controller?

the case for physical games: put the cartridge on the high shelf

jareklupinski··on AI-Assisted Cognition Endangers Human Development
> What would you think about your life? Would you think "this is horrible" or "this is fine"? Or maybe "I enjoy smell of shit and we're so much better off because we don't have to worry about sunburn"?

id probably start with "who locked us in this sewer?"

jareklupinski··on 'Seeking connection': video game where players stopped shooting, started talking
"It Takes a War" gets into the social part of multiplayer action games: https://store.steampowered.com/app/3919530/It_Takes_a_War/

(the store page and gameplay videos are purposely obtuse, its one of those 'dive in with no precognition for best results' kind of games)

jareklupinski··on Show HN: I built a social media management tool in 3 weeks with Claude and Codex
RSS can get you there, lots of clients but you have to teach your friends how to make their own websites and set up a feed

made me think of Pidgin, the chat client that could talk to any chat server

jareklupinski··on Filing the corners off my MacBooks
> why are they so sharp?

they intentionally ship them sharp so you can file them down to your desired fillet

the design is very human

jareklupinski··on Combining spicy foods with mint boosts anti-inflammatory effects 100x or more
chase it with a shot of espresso for 1000x increase
jareklupinski··on Many African families spend fortunes burying their dead
a couple can have a really big wedding for a really decent price if they plan everything themselves / with family

if they go through a planner, the 'coordination' eats most of the budget, almost entirely so if 'their people' get involved with setup / teardown

jareklupinski··on John Deere to pay $99M in right-to-repair settlement
yea, the tractor is a lambo

jareklupinski··on Ask HN: Any interesting niche hobbies?
there's a print shop nearby that does workshops, i took a short class there and i'll soon be back with some design files, hope to make a few copies of a zine about publishing a website on the internet
jareklupinski··on Zooming UIs in 2026: Prezi, impress.js, and why I built something different
very well made :) for documentation and specific dashboards this has a lot of great uses

i played with a similar concept back when everyone was starting to 'drill down into big data' on their ipads, and i never came up with a clever way of drilling 'sideways', or allowing people to go between one 'insight' from one deep level and tie it into another without zooming all the way back out and then back in, contextual 'wormholes' (all handmade), or breadcrumbs (messy after enough layers)

one thing i'd add to the demo is detecting where i'm hovering over while scrolling to scroll into that part (on a mouse), scroll out works

jareklupinski··on A brief history of instant coffee
i read it in Don Draper's voice
jareklupinski··on Show HN: Real-time AI (audio/video in, voice out) on an M3 Pro with Gemma E2B
just make it say "Uh...", "umm...", or "hmmm..." once or twice halfway between processing and finish :D
jareklupinski··on One ant for $220: The new frontier of wildlife trafficking
just thinking that, as a buyer of a rarity who is presumably showing it off to others eventually, i'd probably get more mileage out of a photo of me sticking a twig into a dune, and then a tale of 'smuggling a single ant', than 'i got this myself, from one whole trip to the store'
jareklupinski··on Bacteria found in the human intestine capable of improving muscle strength
yes! i'm hoping to understand more about the beginning of this co-existence, to maybe better work out ways to make their metabolism interact with ours in more helpful ways, will start that list from 7 backwards :) ty!

https://pmc.ncbi.nlm.nih.gov/articles/PMC8061703/ is around where i started, some time after learning about https://en.wikipedia.org/wiki/Auto-brewery_syndrome

jareklupinski··on I won't download your app. The web version is a-ok
> the website is completely broken or the devs force me to download the app by blocking features on the website

for me, this is signal that i wasn't supposed to be visiting that resource in the first place

jareklupinski··on One ant for $220: The new frontier of wildlife trafficking
"The foreigners never came to the fields themselves - they would wait in town, in a guest house or a car, and we would bring the ants to them packed in small tubes or syringes they supplied us with."

i never got the appeal of having someone else do the only interesting part of anything for you

jareklupinski··on Bacteria found in the human intestine capable of improving muscle strength
my only credential is a bio-eng degree, but i read a lot and hope to put together a novel or something to get ppl thinking about it, until we can find a way to test the hypothesis
jareklupinski··on Bacteria found in the human intestine capable of improving muscle strength
> We are what we eat.

putting together a theory on how bacteria organized multicellular life to exploit our macro-movements and proliferate between damp spots

jareklupinski··on LLM Wiki – example of an "idea file"
im hoping to re-use the newly garbage-collected memory available to me now to rediscover "play hard"
jareklupinski··on Costco sued for seeking refunds on tariffs customers paid
wouldnt the average refund come out to basically a free year of membership? the easiest thing for them to do might be just check who was a member during the tariffs, and credit their membership fee for the 'tier' they were buying

people using costco as basically a small-business depot would be lifetime non-transferable free members, and typical family/consumer gets some extra years, which they'll turn around and spend in the store anyway

win/win? costco members are sticky, and refunding cash is hard

jareklupinski··on Some Unusual Trees
> but you know wood? You know when you hold something in your hand, and it’s made of wood, and you can tell that? Yeah, that thing.

everyone should have a copy of Identifying Wood on their metal bookshelf
