out_of_protocol··on How much information is in DNA?
> There's less than 80 minutes worth of music's worth of information

Or awful lot of text information (state of art compressors can do up to 1:10 ratio for plain text, decoder itself is rather small, 750MB compressed could potentially contain like 7GB of text data).

Also, look at demoscene. 4k (4 kB is the size of executable) can do crazy things, and 64kB can fit a lot of nice 3D objects, music, text, complex effects etc. weight less than any screenshot of any moment of running demo. In 95kB you can have full game (google kkringer)

P.S. better example: full snake game in 56 BYTES https://github.com/donno2048/snake

For comparation the link above is 34 bytes, whole sentence is 83 bytes. It's possible to do a lot if we're talking about code

out_of_protocol··on How much information is in DNA?
DNA self-desintegrate very fast. It only works in living cells because it is being repaired non-stop
out_of_protocol··on Why it is (nearly) impossible that we live in a simulation
Or it could be Half-Life 10⁹⁹, with stylized graphics and simplified rules (main action goes within another galaxy and we are a background noise). We're talking unknown unknowns here
out_of_protocol··on EU to ban anonymous crypto accounts and privacy coins by 2027
How do you do that on DEX?
out_of_protocol··on Show HN: MP3 File Editor for Bulk Processing
Losssy-to-lossy is a bad idea. Getting mp3 off YouTube means very crappy experience, even if it is somewhat popular
out_of_protocol··on I tried Windows gaming on a Mac
> Linux ABI is available— Win32

Yep!

> Mac users are generally running on aarch64 rather than x86, so you have the binary compatibility barrier. Plus no 32bit support.

That's not really the reason. Rosetta exists and quote good. Macos binaries don't work because Apple breaks its own compatibility (including 32 bit thing), and windows binaries don't work because Apple don't support vulkan nor opengl, and, maybe even more important, no one has incentive to fix it

out_of_protocol··on Tesla celebrates key milestone for 4680 battery cell production cost
Also 4680 better than traditional 18650 due to bigger size and therefore less money and space spent on casing
out_of_protocol··on California now has more EV charging ports than gas nozzles
> BYD will soon start deploying its 1000 kW ultrafast charging stations in China. The first batch of 500 chargers will begin operating in early April

> ZEEKR unveiled a 1.2 Megawatt EV charger

So it's possible. Hard to do though, 1-10MW of available capacity is hard to come by, infrastructure is not ready. Well, gas station infrastructure was built over more than a century of gas domination

out_of_protocol··on Nintendo unveils Switch 2 ahead of June 5 launch
470€ vs 570€ for OLED 512GB. With 80€ (digital, 90€ physical) base price for a game, you'd probably go break even in like 2-3 games, especially when buying games on sales (Nintendo don't do that) and older titles (Nintendo don't discount these either)

P.S. $450 vs $550 for US

out_of_protocol··on Closing the Chapter on OpenH264
vp9 is widely used (e.g. YouTube is mostly vp9, av1 and fallback h264) and not much worse
out_of_protocol··on A New Form Factor for Drones: Vertical and Coaxial
Standard 4-engine copter is VERY simple hardware wise - 4x blades+engines attached directly to a frame, plus some orientation sensors stolen from a phone. And that's enough to maneuver in any direction with ease, with turning radius of zero. That's why the whole industry is booming
out_of_protocol··on Did the Particle Go Through the Two Slits, or Did the Wave Function?
Wiki, citation 19

> The largest entities for which the double-slit experiment has been performed were molecules that each comprised 2000 atoms (whose total mass was 25,000 atomic mass units).[19]

https://en.m.wikipedia.org/wiki/Double-slit_experiment

out_of_protocol··on Did the Particle Go Through the Two Slits, or Did the Wave Function?
Double slit experiment did happen and totally reproducible even then photons/electrons are sent by one at a time.

"two photons come out" part makes no sense though. On a target side, there's always single hit after single photon/electron, but distribution of theses hits as if said electron got through both slits and interfered with itself

P.S. the funny thing is - this works on any small thingy, measured up to 2000 atoms-big, as if it's the property of the universe itself

out_of_protocol··on Microsoft begins turning off uBlock Origin and other extensions in Edge
No one cares for specifically V2, it's just V3 is intentionally crippled. Just allow functionality required for more feature-rich extensions like uBO and everyone will forget V2 very fast. V3 does allow extensions to monitor and sell network data (no privacy improvements), but blocks modifications (no cutting out ads)
out_of_protocol··on Microsoft is killing Skype
That was the funny story - Nokia got it's latest CEO (Stephen Elop) from M$, successfully almost-destroyed company, got it acquired by M$ and hopped back to M$. So, probably, it was the plan all along
out_of_protocol··on If it is worth keeping, save it in Markdown
Mermaid charts! Supported by github and very readable as plaintext

out_of_protocol··on “A calculator app? Anyone could make that”
Well, this one is on google. "Full filesystem access" is restricted to specific classes of apps like file managers, and replacement api is very shitty (have lots of restrictions, slower by orders of magnitude)
out_of_protocol··on YouTube audio quality – How good does it get? (2022)
Just use DAC with S/PDIF output, and another one with S/PDIF input. Well, either way it's hard enough to block casual users, so... it works
out_of_protocol··on YouTube audio quality – How good does it get? (2022)
Opus _IS_ transparent at 128 kbps, big IF - encoded properly. YouTube does some weird shit instead of just reencoding
out_of_protocol··on YouTube audio quality – How good does it get? (2022)
251 is codec format ID. Real bitrate is around ~135 kbps
out_of_protocol··on YouTube audio quality – How good does it get? (2022)
Regular user can get up to YT-251, which is described in article, ~135kbps opus (i think target is higher, 160 kbps or so). But bitrate itself is good enough - on good headphones I can't distinguish flac vs opus-110kbps, except very rare killer samples. And YouTube audio clearly lacks detail despite having higher bitrate. So, probably, 256 kbps would not help much
out_of_protocol··on Ask HN: Would you still choose Ruby on Rails for a startup in 2025?
From my experience supporting Rails app longer than a month becoming more complex due to a lot of meta-magic (method_missing and friends, abused by rails itself). Elixir/Phoenix feels exactly like Rails with these issues fixed. Longest living production app is ~8 years now, doesn't feel like legacy at all. Upgrades are easy. Easy to figure out what's exactly happening right there.

Also, resource consumption/optimization. I noticed i need to do something about it on first week of development, which is sad (and spends dev time on non-relevant stuff). Phoenix designed to avoid it (including stupid stuff like N+1 problem)

out_of_protocol··on When AI promises speed but delivers debugging hell
Very maddening, some regular phrasees can be interpreted in multitude of ways, often contradictory. Even with full context it's still ambiguous
out_of_protocol··on When AI promises speed but delivers debugging hell
It did, e.g. Poland have very good bang for buck ratio. Something like Bangladesh wouldn't work for IT, but more developed countries will
out_of_protocol··on WASM GC isn't ready for realtime graphics
Really liked NaCl (and PNaCl) idea, which allows running arbitrary code, sanitized, with ~90% speed of native execution. Playing Bastion game in browser was refreshing. Unfortunately communication with js code and bootstrap issues (can't run code without plugin, no one except chrome supported this) ruined that tech
out_of_protocol··on Bye-bye Windows gaming? SteamOS officially expands past the Steam Deck
SteamOS does provide support for common anti cheats (don't know details though), made in collaboration between anti cheat maker and valve, but many games decide to specifically opt out of this support
out_of_protocol··on Nvidia announces next-gen RTX 5090 and RTX 5080 GPUs
Also, ultrawide monitors. They exist, provide more immersion. And typical resolution is 3440x1440 which is high and and the same time have low ppi (basically regular 27" 1440p monitor with extra width). Doubling that is way outside modern GPU capabilities
out_of_protocol··on Nvidia announces next-gen RTX 5090 and RTX 5080 GPUs
Well, modern games + modern cards can't even do 4k at high fps and no dlss. 8k story is totally fairy tale. Maybe "render at 540p, display at 8k"-kind of thing?

P.S. Also, VR. For VR you need 2x4k at 90+ stable fps. There's (almost) no vr games though

out_of_protocol··on Rails for everything
Well, i think Elixir/Phoenix is better Rails than real Rails - great developer experience (and developed by rails contributors)
out_of_protocol··on QR-style codes could replace barcodes 'within two years'
> Yes I can guess an ID. So what? I don't understand the threat model here.

can print fake cola codes for infinite refills :) and some other genuine cola buyer will be very angry because their mint-condition bottle already used up. Also, "one in a million" assuming this tech is only being used by this specific product. if anyone else is going to use the same schema for anything else, numbers will dry up much faster. bringing oats as valid cola bottle is funny. if you add prefix, it'll eat up these sweet sweet bytes

also, 1/million is not that much - you can spam online check api (and you need one with just IDs) to filter out existing ones. All in all 64-bit or so IDs have too many downsides to consider them useful, one simple misstep and the whole model is broken

> Unless the number was copied.

yep, also used up by different device
