PBnFlash··on Show HN: Bigwords.page – Turn any screen into a sign. The URL is the app
I use to try and coordinate game nights across the world, and a url with the Unix timestamp of the event and a countdown showing how many days and hours worked quite well.
PBnFlash··on Trick users and bypass warnings – Modern SVG Clickjacking attacks
Reminds me of the flash player hack that would trick people into enabling system storage while hiding the menus. Vectors just can't help themselves
PBnFlash··on Meshtastic
It seems like big cities get congested, on marginal systems the chances of only getting half the messages is very high. It really dosnt integrate with much else, the mqtt stuff seems unreliable.

It does seem like the RNode radios are a lot less mature but they seem to be aiming to be less of a toy.

PBnFlash··on PG&E reports profit of more than $2B for 2024
Because they killed dozens of people and destroyed a town though lack of re-investment and monitoring their infrastructure.
PBnFlash··on Storing Times for Human Events
I had a little page that would encode Unix time of the event in the url, then just count down.

Super reliable.

PBnFlash··on YouTube: Google has found a way to break Invidious
They are artificially suppressing the api value by banning uses people want. If people want to opt out of the recommendation engine and ads that makes hosting cheaper and easier for YouTube. They only do it to leverage market position and imo that's bad.
PBnFlash··on Boom announces successful flight of XB-1 demonstrator aircraft
What is with the sudden surge of hypersonics? Surely this is military funding on some level?
PBnFlash··on New jet engine enables efficiency at every speed for cheaper orbital launches
This seems to not have consideration for hypersonic air flow. If this is just a lifting engine it can only provide a small fraction of delta v.
PBnFlash··on SpaceX discloses cause of Starship anomalies as it clears an FAA hurdle
Worth noting that flying to the equator can provide a pretty significant increase of payload mass. Just a quick layover to orbit.
PBnFlash··on A Quadrillion Mainframes on Your Lap
The 1980s chip Doc Brown made on the hood of a car in Back to the Future 2 was about 6 square feet, modern chip would need to be the size of the Pentagon.
PBnFlash··on Why it's impossible to agree on what's allowed
If we ignore the law of universal gravitation the ambulance can hover over the park.

Rules are a part of how the world works as is the violation of them. Thought problems that deviate so far from reality are more a test of abstract thinking.

Rules implicitly exist for terminal goals (don't kill the grass in the park so people can enjoy it) but get abstracted into actionable decrees that are not necessarily aligned (Becky can't enjoy the grass if she's dead.)

PBnFlash··on Permutation City (1994)
If you can handle the science changing since publication in the 1930s(!!!) Olaf Stapledon is simply remarkable. "Last and first men" is one of my favorite books for just how unique it is, but "star maker" has some interesting parallels
PBnFlash··on Sam Altman Seeks Trillions of Dollars to Reshape Business of Chips and AI
There are probably a lot of optimizations in the silicone and software to find. It's not necessarily obvious what corners can get cut or where, the tradeoffs of tapping out new chips is worth it. Yet Another Matrix Multiplication Chip is not going to set the world on fire. Nvidia has that market pretty well captured.

But perhaps it turns out that subnets can be trained independently or swapped with semantically equivalent but qualitatively different ones. The routing network would effectively "Standardize" and could in principle be well enough understood to "hand optimize" the routing network into hardware. Or maybe back propagation has some novel physical analogue that can be exploited in scales we can access. The real question is if Altman is capable of finding the right path in the notoriously dead end filled field of chip design. His backing of helion [1] didn't bode well in my view. But with enough R&D maybe he will flail into something useful trillions is enough for a lot of flailing.

PBnFlash··on Neanderthals and humans lived side by side in Northern Europe 45,000 years ago
With their bigger brains larger lungs and stronger bodies too expensive in the ice and snow. We the budget model had an advantage but in this time of plenty some neanderthal clones would give us a run for our money.
PBnFlash··on Austin takes a bet on tiny homes to ease homelessness
One upside of minimum wage is lots of places have competitive salaries
PBnFlash··on A Modern Web for Hacker News – Open-Source and Seeking Feedback
I don't want this
PBnFlash··on Double-mirror illusion
This seems like a version of the ambiguous cylinder illusion https://youtu.be/yupxceBjDa0
PBnFlash··on Ask HN: What apps have you created for your own use?
Scheduling events with lots of people and timezones was always a pain. Stick an epoch time into a url for a static portable timer.

PBnFlash··on Transparent wood could soon find uses in smartphone screens, insulated windows
I hesitate to wade into this but he does not do interesting chemistry. I am deep into chemistry YouTube and followed Nile red since literally his first year on the site. He has wonderful presentation, clean videography, and great presentation. But his chemistry is some of the most rudimentary in the scene.

On the opposite side "chemical force" is amazing and borderline unwatchable.

PBnFlash··on State Dept prioritizes 'AI-ready workforce' in its first AI strategy
Ah well, they probably wouldn't have moved fast enough even if they were going in the right direction.
PBnFlash··on U.S. agency declares 21 species now extinct
Transplanting hundreds of species around the world in viable groups is probably a bad idea too.
PBnFlash··on Pistachio billionaires accused of artwashing California's water crisis
Not a great reason to pointlessly flagellate ourselves.
PBnFlash··on Ruffle: Flash Player Emulator
New grounds has a "flashforward" event every year or so.
PBnFlash··on Amazon launches Project Kuiper satellite internet prototypes
The wide angle and time lapse of these massively overstates the problem. The angle they cover is microscopic and they only cover it for an instant. In visible spectrum I find it very hard to believe it is a more serious problem than earth based astronomy already deals with like atmospheric issues.

Radio looks pretty bleak, noise floor is about to get a lot higher.

PBnFlash··on Decomposing language models into understandable components
The way these systems work feel massively inefficient.

We don't re-evaluate our astrophysics models when reading a cooking book.

PBnFlash··on The Details Are in the Devil’s Tumors
I found it weird how they didn't mention that the other transmissible cancer was. They are probably referring to golden hamsters, but according to Wikipedia there are three animals that have transmissible tumors like this so 2/4 for the devils.

PBnFlash··on Croc: Easily and securely send things from one computer to another
It's based on webtorrent, so it will p2p but it is dog slow for serious files.
PBnFlash··on The AI explosion might never happen
Our use of data is WILDY inefficient currently.

Current training systems extract information on everything from every input. We don't read a cookbook to learn about space, but these models are twiddling weights all over these massive spaghetti balls of logic.

Looking at the data we have, the literal collection of all human knowledge and lamenting not having more is like standing on a ladder sideways.

But it's really starting to feel like pile of ladders is getting tall enough to bootstrap.

And these massive inefficient systems filled with data and churning matrixs will be set in order. And all the ladders laid end to end.

PBnFlash··on Google DeepMind's AI successor predicts how 71M mutations cause disease
This will be 100x better before the first treatment hits human trials. Imagine how powerful these systems would be with all of the health data the world has in paper vaults.

These are crazy times.

Now that covid is endemic it's just another flu.
