    We added the transpiled code in a new branch at https://github.com/immunant/ioq3/tree/transpiled/quake3-rs and also a more cleaned up refactored code base at https://github.com/imm…

    Author here: I wanted to let everyone know we made some small edits to the text, and added two new branches to our repository: transpiled containing the raw transpiler output [1], …

    Right, I see that now. Adding an additional layer of RSA and per-file keys is an interesting twist. Generating a public/private key pair instead of a symmetric key seems to let the…

    I don't know the exact details of how WannaCry encrypts the files, but ransomware generally works like this: when hitting a new machine, it generates a random key K1 and then encry…

    There doesn't seem to be anything dynamic about the algorithm in the article. They still need to precompute the perfect hash function(s) from the entire input data, whereas the has…

    1. and 2. are OK points, but your point 3. is atrocious. In my opinion, destructive behavior isn't really a legitimate form of protest, and as rubidium wrote, you'd be hurting peop…

    Anything that is valuable, fungible and divisible could be used as money (you could even use barrels of oil). For examples, see [1]. Again, a great contemporary example is Bitcoin …

    Money is both a "unit of account" and "medium of exchange". You can certainly have both of those without government. In some societies, people used seashells, salt, gold coins, or …

    AFAIK, V8 already has 3 tiers: full-codegen (the basic non-optimizing JIT), crankshaft and turbofan. With ignition, they're replacing full-codegen with an interpreter. It's strange…

    size_t is also unsigned (no idea why). The signed equivalent is ssize_t. Edit: Sorry, missed the "i-- > 0" at first. The code works, but not because of changing "unsigned" to "size…

    If you mean run RPython code as regular Python code, that doesn't always catch typing problems. For example, returning a None where an int is expected works fine in Python, not so …

    I used RPython on my own interpreter project a few years ago (stopped working on it around 2013). It's a very interesting approach to writing interpreters/JIT compilers, and produc…
