Charon77··on Prove you are a robot: CAPTCHAs for agents
"一 百 二十 一 dollar "

Definitely chinese.

In Japanese, they say 'hundred' instead of 'one hundred' "百 二十 一"

Charon77··on Bluesky has been dealing with a DDoS attack for nearly a full day
True. The only 'distributed' part of bluesky is in the PR. Otherwise there'd be more instances.

My mastodon account is not even on mastodon.social, because why would I, when I could have a home server closer to home

Charon77··on Roblox devs now need a subscription to share their games freely
a bit misleading title.

> Publishing games that are available to players with either Roblox Kids (users under 9) or Roblox Select (users 9 to 15) accounts that we announced in our Newsroom will require additional verification steps than publishing games that are available to users over 16.*

Charon77··on All elementary functions from a single binary operator
x+y = ln(exp(x) * exp(y))

exp(a) = eml(a, 1) ln(a)=eml(1,eml(eml(1,a),1))

Plugging those in is an excercise to the reader

Charon77··on All elementary functions from a single binary operator
Not brainf*ck. This is the SUBLEQ equivalent of math https://en.wikipedia.org/wiki/One-instruction_set_computer#S...
Charon77··on Simplest Hash Functions
> Like addition

I'm perplexed to the claim that addition is cheaper than XOR, especially since addition is built upon XOR, am I missing anything? Is it javascript specific?

Charon77··on Simplest Hash Functions
Well it no longer constrains the data in a fixed output length.
Charon77··on Industrial design files for Keychron keyboards and mice
They have a switch tester board where you can press individual keys and you can see which switch you just pressed on the screen
Charon77··on Introduction to Nintendo DS Programming
I think 3ds is also reasonably in the sweet spot.

Check out this project, fully written in bare metal C

Charon77··on SSH has no Host header
What good does certificate format do? Certainly won't make people not reuse it the same way.

> where the affected users might be surprised or alarmed to learn that it is possible to link these real-world identities.

I feel like it's obvious that ssh public keys publically identifies me, and if I don't want that, I can make different keys for different sites.

Charon77··on SSH has no Host header
They don't want each vm to have different public IP
Charon77··on Forget Flags and Scripts: Just Rename the File
If the rename changes the entire behavior (see busybox comment) it makes sense. But defining multiple arguments? Now the author had to use -- in the file name where using space would do (and the OS splits it for you)

And good luck trying to run the same programs with different arguments. You'll have to take turns renaming the file, or create hardlinks just for ephemeral arguments.

It can be useful but there's time and place to do it.

Charon77··on How kernel anti-cheats work
I remember there's a PCI device that's meant to be snooping and manipulating RAM directly by using DMA. Pretty much one computer runs the game and one computer runs the cheat. I think kernel anti cheats are just raising the bar while pretty much being too intrusive
Charon77··on MetaGenesis Core – offline verification for computational claims
First of all, I don't want to run anyone's code without proper explanation, so help me understand this. Let's start with the verifier. The 3rd party verifier receives a bundle, not knowing what the content is, not having access to the tool used to measure, and just run a single command based on the bundle which presumably contains expected results and actual measurements, both of which can easily be tampered. What good does that solve?
Charon77··on I was interviewed by an AI bot for a job
Interview is a two-way communication. Just as companies evaluating the candidates, the candidates are also evaluating the company.

How would the company feels if the people applying uses AI avatar to answer the interview questions too?

Charon77··on Show HN: Mcp2cli – One CLI for every API, 96-99% fewer tokens than native MCP
MCP only exists because there's no easy way for AI to run commands on servers.

Oh wait there's ssh. I guess it's because there's no way to tell AI agents what the tool does, or when to invoke it... Except that AI pretty much knows the syntax of all of the standard tools, even sed, jq, etc...

Yeah, ssh should've been the norm, but someone is getting promoted for inventing MCP

Charon77··on Put the zip code first
In Japanese websites this is pretty much the norm. Govt, bank, marketplace, you name it. fills the address until the block, where you'll need to fill the rest of the numbers until your house address / room number
Charon77··on Motorola GrapheneOS devices will be bootloader unlockable/relockable
The whole point about having an open platform from boot is you don't have to trust it. You run your own code from first power on.

Is it possible that it's backdoored, have a secret opcode / management engine? Probably, but that goes to everyone, as it's not practical to analyze what's in the chip (unless you're decapping them and all)

I don't know what secure environments you're talking about, if it's an airgapped system then you should be secure even when what's inside 'tries to get out'.

Charon77··on Interview with Øyvind Kolås, GIMP developer (2017)
I think if Blender can do UI change, GIMP should too.
Charon77··on “Car Wash” test with 53 models
I'm doubting the 29-ish percent of people submitting 'walk' are actually human.

Is it not obvious that you need a car to wash?

Are they using LLM to answer?

Charon77··on Untapped Way to Learn a Codebase: Build a Visualizer
In reverse engineering we often use Graph View to see execution flow as well. Glad to see it being used elsewhere
Charon77··on Show HN: FaceTime-style calls with an AI Companion (Live2D and long-term memory)
You need to first prove that AI is not conscious.

I find it hard to even convince others that I am a conscious person.

Maybe consciousness is just a matter of belief, if I see this AI and believe that it's a person, then I am talking to a conscious entity.

Charon77··on An Experimental Approach to Printf in HLSL
Not putting strings on GPU looks very much like how some system approaches semihosting
Charon77··on Ask HN: What Are You Working On? (December 2025)
I'm working on a game for pocketstation (essentially Dreamcast VMU, but Playstation). It has the same cpu architecture as GBA but there are some unfortunate circumstances that requires me to modify LLVM for rust to use. Forces me to learn I guess
Charon77··on Show HN: Neural emotion matrix for NPCs
Looks really cool but I'm wondering if the whole Docker setup was necessary just to get onnx?
Charon77··on Everyone's trying vectors and graphs for AI memory. We went back to SQL
Have you considered using prolog as a database instead of mysql?

Good ways to store relations, iterating weird combinations, filling the blanks

Charon77··on Dear GitHub: no YAML anchors, please
Just run the code and see the output.

There are multiple ways to safely run untrusted code.

I for one enjoy how build.rs in rust does it: you have a rust code that controls the entire build system by just printing stuffs on stdout.

There are other ways of course

Charon77··on I uncovered an ACPI bug in my Dell Inspiron 5567. It was plaguing me for 8 years
B)

This. I really wish I could be workikg in hardware, but the salary incentive is just there. Now I am stuck doing backend job to afford life and my low level and hardware hobby (reverse engineering games and firmwares, emulator, fpga stuffs), things that are magnitudes harder than making an api that put stuffs in DB and kafka

Charon77··on RustGPT: A pure-Rust transformer LLM built from scratch
Absolutely love how readable the entire project is
Charon77··on Microsoft is officially sending employees back to the office
Not short sighted if _that_ is the goal. Maybe it's just to cut off people they have overhired during the pandemic. Maybe they just need fresh faces without costly layoffs
