A related interesting problem is superpermutations [1]. This is the same problem that an anonymous 4chan poster helped bring some light to lower bounds on shortest superpatterns [2]. The Google group is worth a shout for their efforts [3].

As others have commented, $14.5 trillion USD (even with inflation) is nothing compared to the US's current outgoings. What I _never_ see costed is the other side - what negative cost will the climate policies have on GDP? I imagine tha

Hence why I wrote "For an ultra simple hash table". I think that for C that doesn't natively have such a data structure, a couple of lines to introduce such a structure really isn't too bad.

Key collisions are of course a problem. This is a quick and dirty implementation. If you care about checking for collisions, you could instead have: typedef struct{ char* k; char* v; } KV; int L = <table length>; /&#x2F

You would of course check whether there is a collision if you care. You would size it such that a collision is low probability though.

For an ultra simple hash table, you just need a few things (the following is from my head). First is a 'reasonable' hash function (although with a few more lines you can do better [1]): unsigned int H(char* s){ int h; for(h

The best thing to happen to KiCad was skidl [1] paired with freerouting [2]. You can spin a board in so little time it's insane. In the future I will be looking to automate even the parts placement too. P.S. If there is interest I will

I've always wondered why there isn't a `free_all()` function (that I'm aware of) for exactly ensuring that handles this. Or why you can't probe memory, with something like `is_alloc()` (is allocated). I usually define my

Thinking about it, this could be the way forwards. Memory offers several natural bottlenecks: 1. Memory size - Memory is somewhat costly (even now), with most entry laptops being stuck in the range of 8GB. 2. Access bandwidth - Getting a CP
