Android apps absolutely support deep links: https://developer.android.com/training/app-links (surely iOS supports this too?) It's also widely implemented in practice. For example, Instagram allows copying links to

You're assuming there is a single HN hivemind. In reality different companies cater to different audiences with different values, and you'll hear from a different subset of HN users on each topic. Mozilla users care more about pri

Even then you are depending on the integrity of your development environment (see: Ken Thompson's compiler hack).

Surprisingly, no, or at least it's not common. I'm from a country that has 6-digit PINs on most cards, and I've traveled to e.g. the United States where people are surprised that credit card PINs can be more than 4 digits, bu

Not to worry. We'll just switch to 8 digit PINs and we'll be safe once and for all.

The new filesystem APIs were introduced with Windows 95, so there was no backward compatibility to break. New programs using those new APIs were forced to support spaces in directories. Using spaces in the system directories forced appl

Kinda ironic that because of this post I went to check out php.net for the first time in like a decade, and it turns out the site is down. Doesn't exactly instill confidence that the project is alive and well.

Have you looked at the PyPy benchmarks in the article? Broadly speaking, PyPy is to Python as v8 is to JavaScript.

In general please don't use Soundcloud to share music. It's complete shit. It doesn't even allow seeking unless you register for an account. At least Youtube is borderline usable without signing in.

Not technically ternary because the number of arguments is variable, but definitely an interesting case. `a.b(c)` is actually a bit of a degenerate case because `b` must be an identifier, it cannot be an arbitrary expression, which seems to

To each their own, but the puzzles you linked seem really convoluted compared to regular Sudoku. The last puzzle has no fewer than 9 custom rules, in addition to the regular Sudoku rules, and then it also says “every clue is wrogn [sic]” im

There is no law that says /tmp must be on tmpfs, and historically this wasn't done, because tmpfs is limited in size to some faction of the kernel's memory, while /tmp may be used to store much larger files. For example,

This is a fairly standard dynamic programming problem. The crucial insight is that if you take two pins with a single ball, you split the problem into two independent subproblems, so the core question is when to hit two pins at once. This l

That's not what precise GC means. Precise means that on a GC cycle, only true pointers to heap allocated objects are identified as roots, which means that an unreferenced object cannot be kept alive by a value that happens to have a si

Great point! Actually this observation invalidates the whole setup. Because even though you could define /bin/sh itself as: #!/bin/busybox sh exec /bin/busybox sh Then you still cannot use #!/

`busybox whoami` is probably fine, but having to write `busybox ls`, `busybox grep`, `busybox cp` etc. would get tedious quickly. Shell aliases don't solve all problems, even if you do: alias rm="busybox rm" alias x

Your logic is correct but you are off-by-one. 1 guess gets you 1 number, so the formula is 2^k - 1, and 7 guesses thus covers 127 numbers. You can also view it as a recurrence: f(1) = 1 f(n) = 2*f(n - 1) + 1 = 2^n - 1 But your bina

It's common for neural networks to struggle with negative prompting. Typically it works better to phrase expectations positively, e.g. “be brief” might work better than ”do not write long replies”.
