Are you saying that these things are somehow not happening in Mariupol? We already know that Mariupol has been a subject of population abductions at the very least.

You will not convince anyone sensible that the morals and discipline of US troops and officers are anywhere close to the morals and discipline (or the lack thereof) of their Russian counterparts with this whataboutism.

Furthermore, Russia is not doing anything that it hasn't already been doing for almost a century.

You already are autogenerating code in Lisp (using macros), but not without keeping the source for it, which still lives in the source files. If those files are not loadable into a clean image, you're doing something wrong (like CMUCL

Not quite. For example, languages like Python typically have generative class definitions -- meaning that a class definition always creates a new type, with no existing object instances being objects of that class. In comparison, Common Lis

My humble LP needs have always been satisfactorily fulfilled by QSopt and COIN-OR solvers (Clp/Cbc). I guess I'm just too boring for anything fancier.

Generally in CL you should be able to recover from a usable intermediate state and restart from there.

Hydropower actually has strong carbon-related undesirable environmental consequences, but probably not to such an extent in California as it does in Africa and South America. You'd have to find dam-specific data to verify that for Cali

Common Lisp implementations allowed you to change your program's code while debugging decades ago. Microsoft added bare minimum of similar functionality like fifteen years ago or so, if I remember correctly. I'm not even sure they

Depending on location, hydroelectric power can have (mostly because of decomposing vegetation) carbon-equivalent emissions ranging from several grams of CO₂ per kWh, all the way up to around two thousand grams (!) per kWh. This greatly depe

What financial hardship? Pretty much all the other pathways are even more expensive, either in externalities or in internalized costs. There really are not that many realistic options that remain open (at least in the US).

Well, damn. I imagine the reason why didn't know about this is because I have never been able to formulate any of my particular problems in terms of Euclidean TSP (even just metric was hard enough at times), so all interesting stuff wa

As I noted, you'd probably want to do this conversion before import anyway, so none of the results may be of practical interest if you decide to go down that road. But maybe query performance tests on already imported data would be of

Even memcpy would be more that fast enough, though. This just seemed like a weird test to me since instead of testing "which [database] can convert a set of coordinates into H3 identifiers the fastest", it seems more like a test o

I have to wonder -- considering that H3 is apparently available as a C library -- how fast it would be to simply enrich the lon/lat data with H3 data using a simple Unix filter using that C library before even importing it anywhere. (O

No, there aren't? The last time I checked, the best polynomial-time approximation algorithm to symmetric TSP (Christofides) could only guarantee finding a tour with no more than 3/2 of optimal length. Has something better been fou

Is ABA an issue here? "Replace A by X*A" should be perfectly fine if an atomic swap gives you A back, since it means it was actually A at the time when you perform the swap. That it was B a moment go doesn't seem to matter.
