The phrase "that you take a limited amount " implies that the amount taken is the primary determining factor. For example, that (at least approximately) taking four tiles is always safe, regardless of which four, and taking fou

Like with most things, the problem is usually that we can't find peripherals that are actually nice, rather than overpriced (and endorsed by shills). If the options are paying 40$ for a shitty keyboard, versus paying 400$ for a still

For a arbitrary Apter Tree, a linear scan is unordered. You can impose additional constraints to get a ordered traversal (in the same way that, eg, you can sort a assoc-list/JSON-style key-value table by keys to get a key-order trave

... `if`, `then`, `else`, `while`, `return` vs `goto`, `comefrom` ... Well, it's arguably superficially a better argument than Dijkstra's, but it doesn't account for `for`, so I'm not convinced.

More to the point, try `[len,exit,repr]`. Consider what would happen if `exit.__repr__()` did terminate the program.

True, but my parenthetical was covering the opposite issue: it's possible to not realise DUAL_EC_DRBG is broken (rather than impossible to realise it) if your only knowledge of cryptography is, say, hash functions and stream cipher
