jareklupinski··on Ask HN: What has been bothering you lately?
i live in the US and cant get something sent here to save my life

i used to get weekly packages from indie european stores and samples from asia

since tarrifs, that has dropped to zero, with 90% of my shipments being returned for cryptic reasons (like 'incomplete address' when the full address is correct and visible) or outright 'No' from sellers

its starting to feel less like random failure and more like "system working as designed" :(

jareklupinski··on Ask HN: What Are You Working On?
whenever i want to play a video game with someone, theres no way to just pick up a couple of controllers and jump into a game without waiting for something to start, or update, or sync, or...

im building a tiny handheld video game (think GBA) where simply turning it on starts the game and you can immediately start playing. no os to boot, bios checksum screen to wait through, or scripts between you and the game. if another person turns their handheld on, they join your game and it becomes multiplayer seamlessly

esp32-s3 based for dual cores (screen updates / game loop) and bluetooth for "local" wireless multiplayer matchmaking, currently making the game itself be like a cross between puyo pop and tetris (an actual mashup of the rules, not just two games in one cartridge)

jareklupinski··on Airlines Can't Charge You for What You Wear
> Maybe if the airline notices that all the passengers are sitting on the left (for some strange reason) or something like that, they would reseat people.

I was on a turboprop plane when they made a few people switch seats to balance the weight: the seats were arranged Seat - Aisle - Seat - Seat , and all the singles on the left side were filled to the back, with only a few seats on the right side taken.

jareklupinski··on Show HN: Free activity calendar for schools, sports clubs, and organizations
the moat between "here is the code on github" and "here is a viable production-scale setup serving this codebase accessible to someone with only a smartphone" is still worth a lot

not to say this can't be ansible'd or something, but at the end of the day someone is paying the server costs

jareklupinski··on Gemini 3.5 Flash
this seems to happen a lot with commercial models; my local models will happily do as much research and then some when given a task (almost too much), but providers' models refuse to even curl a single datasheet before trying something that i know wont work unless it reads the datasheet
jareklupinski··on I Found Ultra-Pure Quantum Crystals in an Abandoned Mine in the Atacama Desert
it's more likely that they used our planet as a "greenhouse" to grow these crystals for themselves, and we're just the lichen that happens to grow on the walls as a consequence of their process

21st century humans had notoriously poor light receptors, so they used these "smart" devices to reflect more sun into their eyes in order to see while hunched over

i've played multiple AAA(+) games before AI 'was a thing' that have had textures/elements, like bulletin boards or posters, where even on cursory glances (not zooming in or ADS) you can easily see literally "Lorem Ipsum" instead of lore or story which would have helped build atmosphere

LLMs had nothing to do with this

jareklupinski··on HDD Firmware Hacking
i still have mine too! managed to talk to the microcontroller and dump its firmware, but didn't know enough about how to make it arbitrarily run code without worrying about ruining it all

jareklupinski··on Extremely Low Frequencies
> In the summer of 1917, he was arranging various types of coil antennas at a receiver test site on the Chesapeake Bay when he accidentally dropped one of the antennas into the water. Strangely enough, the radio receiver connected to the antenna continued to provide good reception even as it sank into the bay.

jareklupinski··on Why Not Venus?
> The development of science on Earth was spurred fundamentally by observations of the regularities of the stars and planets.

perhaps on Venus, it would be spurred on by the creatures there trying to understand why a gaseous swirl goes in a certain direction, or why a vortex does what it does for as long as it has to

they may be better at fluids and flow than we are :) worth sending a message in a bottle at least
