    a cryptographically secure pseudorandom number generator would be nice, too.

    for anyone else wanting to read Elon Musk's story in more depth, I can't recommend "The Engineer" by Erik Nordeus enough. He basically compiled titbits of information from various …

    white privilege? don't you mean anglocentricism? the bias would be equally present if Mark was African-American or Asian-American.

    ... and it's impossible to know for sure that a hash is secure against collisions. For example, MD5 was the standard for hashing for quite some time but is considered broken today …

    realistically you would want to use a merkle tree to hash the source, to make it more secure against a chosen plaintext collision, but aside from that this'd be a great addition.

    it should also be mentioned that Jerry's commentary is _hilarious_ - he's basically the SeaNanners of chess.

    you say that, but minecraft is worth actual money because it sells a product that lots of people want to buy and has a lot of potential for further attached products (servers, DLC,…

    that's just PR - PR companies wouldn't do so well if they pushed stories that showed their clients in a negative light.

    these figures are deceptive considering the UK's comparatively-socialist tax attitude. The biggest thing I would point out is that we have nationalised free healthcare for everyone…

    I think black triangles are only really possible if you're working on software architecture - that bit when you "go into the tunnel" and are working in purely abstract space comes …

    I'm not the parent (I'm GP), but my position is that organic certification is good, but the universal association of "natural = good, synthetic = bad" is only harmful. Yes, farmers…

    your assumptions about cryptographically secure pseudorandom number generators (CSPRNGs for short) are incorrect - one of the key requirements of secure random number generation is…

    uplink is fun, and considered a classic of the genre. In terms of education, the real thing is more interesting - check out places like hackthissite.org or smashthestack.org for so…
