Trung0246on Review: Samsung Galaxy S26 Ultra

Does Live Caption Translate available? I think that feature is only available for Google Pixel which is unfortunate.

Trung0246on Emulating Goto in Scheme with Continuations

Here's my very funny implementation of delimited continuation in plain C with zero ASM usage (with help from a specific compiler built-in)

https://gist.github.com/Trung0246/8f801058212d3bbbef82690a31...

Demo (old version with outdated compile flag but still works): https://godbolt.org/z/n9ch4TM3s

It works for gcc/clang/msvc with -O0, -O1, -O2, and even -O3

Trung0246on Spinning Up an Onion Mirror Is Stupid Easy

Unfortunately I got a hard crash on go 1.25.3 when running this: https://github.com/AlexanderYastrebov/onion-vanity-address/i...

Trung0246on It seems like the AI crawlers learned how to solve the Anubis challenges

My dumb idea is to encrypt each HTML element as chain of encryption that requires full load of an HTML/JS element to get another key to load another HTML/JS element and so on. Key retrieval can be throttled and mixed between client and server side and embedded with each requests to prevent browser load everything at once.

This may tread too close to DRM tho due to element protection scheme.

Trung0246on Perplexity is using stealth, undeclared crawlers to evade no-crawl directives

One way to easily bypass is to let external services fetching robots.txt (archive.org, GitHub actions, etc...) to cache it and either expose through separate apis/webhook/manual download to the actual scrape server.

robots txt file size is usually small and would not alert external services.

Trung0246on Perplexity is using stealth, undeclared crawlers to evade no-crawl directives

I heard that it could be easily bypass through realistic 3D human game model with basic mouth open and head tilt animation, even gmod can do such thing.

Trung0246on Anubis: Proof-of-work proxy to prevent AI crawlers

For no js solution, I think some sort of using optical illusion as captcha could works, especially https://en.wikipedia.org/wiki/Magic_Eye or something like https://www.youtube.com/watch?v=Bg3RAI8uyVw which could cleverly hide captcha answer within animated noise mess.

However these methods are not really accessibility-friendly tho.

Trung0246on Anubis: Proof-of-work proxy to prevent AI crawlers

The performance on mobile is kinda suck tho, took like 30 seconds to wait for PoW on difficulty 4 on Firefox Android. By that time I have to resist the urge to switch to do something else.

Trung0246on ScatterBrain: Unmasking the shadow of PoisonPlug's obfuscator

Trung0246on Copyright reform is necessary for national security

One of my idea was establish a copyright renew system in which first year is free, then for second year the right holder will pay $1 to retain the rights, third year pay $2, fourth year pay $4, fifth year pay $8... which follows the power of 2. If they cannot pay for next year then the copyright will fall into public domain (or allows more restrictive form of non-commercial). Most of the worthless stuff will expire at around 10-15 years. Then around 35-40 years for big works that generate tons of revenue if they can pay that amount.

Trung0246on Tree Calculus

If you means that it would be like this:

    var Z = S(S(K(S(S)(K(S(S(K)(K))(S(K)(K))))))(K))(S(K(S(S)(K(S(S(K)(K))(S(K)(K))))))(K));

Unfortunately not works with the `count_fn` function from the wikipedia page :(, `too much recursion`.

Trung0246on Tree Calculus

Interesting, I tried to convert Z combinator in SKI to this using the lambda calculus example then print out the tree. Untested:

    z = (t (t (t t (t (t (t (t (t t (t (t (t (t (t t)) (t t))) (t (t (t t)) (t t))))) (t (t (t t (t (t (t t (t (t (t t t)) t))) (t t)))) (t (t (t t (t (t (t (t (t t)) (t t)))))) (t t))))) (t t (t (t (t (t (t t))))))))) (t (t (t (t (t t (t (t (t (t (t t (t (t (t t (t (t (t t t)) t))) (t t)))) (t (t (t t t)) t))) (t t (t t))))) (t (t (t t (t (t (t (t (t t (t (t (t t (t (t (t t t)) t))) (t t)))) (t (t (t t t)) t))) (t t (t t))))) (t (t (t t (t (t (t t t)) t))) (t t))))) (t t (t (t (t (t (t t (t (t (t (t (t t)) (t t))) (t (t (t t)) (t t))))) (t (t (t t (t (t (t t (t (t (t t t)) t))) (t t)))) (t (t (t t (t (t (t (t (t t)) (t t)))))) (t t))))) (t t (t (t (t t (t (t (t (t (t t (t (t (t (t (t t (t (t (t t (t (t (t t t)) t))) (t t)))) (t (t (t t t)) t))) (t t (t t))))) (t (t (t t (t (t (t (t (t t (t (t (t t (t (t (t t t)) t))) (t t)))) (t (t (t t t)) t))) (t t (t t))))) (t (t (t t (t (t (t (t (t t)) (t t)))))) (t t)))))))) (t t)))))))

Original tested but unoptimized and also converted using tool:

    var K = a => b => a;
    var S = a => b => c => a(c)(b(c));
    var Z = S(K(S(S(K(S(S(K)(K))(S(K)(K))))(S(K(S(K(S))(K)))(S(K(S(S(K)(K))))(K))))(K(S(S(K))))))(S(S(K(S(S(K(S(K(S))(K)))(S))(K(K))))(S(K(S(S(K(S(K(S))(K)))(S))(K(K))))(S(K(S))(K))))(K(S(S(K(S(S(K)(K))(S(K)(K))))(S(K(S(K(S))(K)))(S(K(S(S(K)(K))))(K))))(K(S(K(S(S(K(S(S(K(S(K(S))(K)))(S))(K(K))))(S(K(S(S(K(S(K(S))(K)))(S))(K(K))))(S(K(S(S(K)(K))))(K))))))(K))))));

Trung0246on I Hate the Letter F

`unsafe` code is a little bit tough since the keyword have an F, unless there's another way to create unsound code by abusing rustc.

There's tons of "pirate" version of the pdf specification, especially on Annas. Hopefully this can help someone implement the driver.

Trung0246on A Type for Overload Set

This is my own version of `OVERLOAD` that works with both, although I forgot how did it works:

    #define FWD(...) ::std::forward<decltype(__VA_ARGS__)>(__VA_ARGS__)

    #define LIFT_CUSTOM(X, CAPTURE) CAPTURE (auto &&... args) \
     noexcept(noexcept(X(FWD(args)...))) -> decltype((X(FWD(args)...))) { \
      return X(FWD(args)...); \
     }

    #define LIFT(X) LIFT_CUSTOM(X, [&])

Trung0246on 6 Laws of Dying Hollywood Franchises

Unrelated but feels like gaming somehow avoided this "milking" cycle of franchises since indies games can thrive alongside with AA/AAA. Although milking happens with franchises like CoD and those EA sports games but beyond that there's always something news in term of concept, genres, etc.

How does the gaming industry does this so well? Is it due to low barrier of entries? Or something else I'm unsure of.
