itsthecourier··on Binance-hacker-1029 – $5.6B stolen from Binance
after years of pursuing this guy/team, the government will catch it then it may proceed to free the guy like it happened with Alexander Vinnik. Who was released bythe US and returned to Russia in February 2025. Guy was exchanged for Marc Fogel, an schoolteacher. mind you. great swap right?

awesome explanation. never thought about the complexity of doing analog and having precision issues because it's not discrete anymore and repeatable

itsthecourier··on AI First Ethical Code
A thought experiment of how would an ethical system would look like if it was developed by AI.

So what happens if an AI goes up to Sinai and comes back with its own idea of what's good and bad. A debate evolving day by day

his not yet is actually:

couldn't workaround Capt has and turnstile, gave him a really small timeframe so it got desperate because it was enough time to test hypothesis and traction

itsthecourier··on The startup's Postgres survival guide
* BRIN indexes are great for append only with an incremental value (a 50MB instead of 100GB index in timeseries data in my case)

* If your disks are ssd and scsi in different volumes, adapt the random cost of io in the config to let the planner now

* if you have RAID controller and a Battery-Backed Write Cache (BBWC), you can disable Linux filesystem write barriers. removing excessive fsync from the mouth of the psql demigod in SoCaL ~linux 2015, Bruce Momjian IIRC

* monitor disk usage, in backups pipe to gz, never to disk

* counter-intuitevely modern hardware may have an io bottleneck and plenty of cpu, so try Filesystems like ZFS using Zstandard (zstd), for boost in your Transactions per second

* if possible, schema multitenancy instead of database multitenancy, instagram talked about this decades ago

* indexes index functions results too, precompute those fields and partial indexes help a lot

* BM25 and FTS in pg are so good you probably don't need Elasticsearch and you will save a lot in de-sync between both of them

* you may be hacked in this brave new world post Mythos, thus, learn PITR to an external only write, no override medium like S3

about the use of ANY, that's perfect for tracking changes on an audit table per field
itsthecourier··on GPT-5.6 Sol Ultra produces proof of the Cycle Double Cover Conjecture [pdf]
yeah, I think what makes this post different was that AI did it. hopefully science will advance faster in the next decades with AI researchers helping

itsthecourier··on Local Qwen isn't a worse Opus, it's a different tool
wanted sovereignty, bought a Blackwell for usd12k, discovered a billing issue in some customer and explains that will cover the card

I don't follow how it supports the decision of buying the card, I would even say using online SOTA models would had caught it earlier without usd12k and monthly electricity being spent

itsthecourier··on Want your images back? Sure... That'll be $5!
storing data over years takes money, so charging for it I can understand

but charging and knowing you don't have any data for this user is a big NO NO

itsthecourier··on Pokemon Emerald Ported to WebAssembly (100k FPS)
bro, I learned a lot, I did it step by step and discussed everything with Claude, then used the knowledge to build an emulator at work for a rtos machine (WIP)
itsthecourier··on Pokemon Emerald Ported to WebAssembly (100k FPS)
some weeks ago I made a Gameboy emulator from zero in rust and then exported it to wasm

took me 3 hours with Opus. Opus knew the whole ISA, clock, bus quirks, etc. from their training without any external docs

itsthecourier··on Lee Kuan Yew's Singapore Story (2023)
"but open immigration policies also carry risks. New waves of migrants will be ethnically different, less educated, and sometimes unskilled…It will gradually dawn on governments that immigration alone cannot solve their demographic troubles and that much more active government involvement in encouraging or discouraging procreation may be necessary."
itsthecourier··on Lee Kuan Yew's Singapore Story (2023)
after being flagged and down voted for mentioning Lee Kuan Yew views on Multiculturalism, I reiterate my comment with a direct quote to keep ynews truthful and not polarized towards the left:

"They are implacable in wanting to put down all who do not agree with them."

"What role does Islam itself play in fueling Islamic extremism? Muslims want to assimilate us. It is one-way traffic…They have no confidence in allowing choice.12 Samuel Huntington sent me a piece he was writing in Foreign Affairs called the “Clash of Civilizations.” When I saw him, I said, look, I agree with you only where the Muslims are concerned, only there…Hinduism, Chinese Confucianism or Communism, Japanese Shintoism, they are secular really. They know that to progress, you must master science and technology…But the Muslims believe that if they master the Qu’ran and they are prepared to do all that Muhammad has prescribed, they will succeed. So, we can expect trouble from them and so, it happened.13 Muslims socially do not cause any trouble, but they are distinct and separate Islam is exclusive."

itsthecourier··on Lee Kuan Yew's Singapore Story (2023)
Trump is testing the limits of USA democracy every day, just from the top of my mind: top lieutenants worth 5%+ ownership in Thether holding company, Ivanka's husband with the Saudis, Ivanka herself in the ONU, shameless plugs of crypto tokens and cards in the podium after elections, pardons for criminals

democracy failed America

itsthecourier··on Lee Kuan Yew's Singapore Story (2023)
been in China for decades, benevolent dictatorships allow long term planning, elections every 4 years favor short term decisions, populism and waste a huge percentage of time in after elections and pre-elections

China and Singapore showed democracy is not necessarily the most productive way to run a country

itsthecourier··on Webcam head tracking, webcam to control in‑game FOV
when your head move, and with it your eyes, you move what's in front of them to your perspective inside the simulation, just as VR works

but in this case it is detrimental because the screen is fixed, the natural behavior would be not to move it

or at least do very little with it like a parallax

the current demo would cause nausea after a moment

itsthecourier··on The newest Instagram “exploit” is the goofiest I've seen
