I have enjoyed this paper on such dynamics: https://sigops.org/s/conferences/hotos/2021/papers/hotos21-s... It is kind of the child of what used to be called Catastrophe Theory, which in low dimens

And it works very well both as SQLite and as a pure go entity. I have used it for few years to do async backups of an in memory counting database (read from only at start up, written to by worker go routine that batches writes) without inci

All this advice is correct, but these questions also show an opportunity to build tools to make answering some types of questions in resl time easy. So I have written scripts to check out all repos under a given org for github, so I pre clo

Having a spouse or friend nag you into going to the doctor is undoubtably a part of the effect, both for the practical side and for the feeling that someone would care if you were ill. (Assuming this is what you mean by "issues with m

Stopping Ebola from becoming a global disease helped Americans.

No but keeping Ebola from becoming a world wide problem is in the US interests and USAID was a very cheap way to advance that goal. We funded USAID out of decency (and to gain a reputation for decency, which is worth a lot of money) sure, b

And our being adapted to many of those struggles - it's a rare person that won't be happier walking 10 kilometers a day compars to walking less than 1. Or happier seeing 1000 trees a day rather than just walls.

This phenomenon is not new; the love of drama that even common and routine trauma leaves many people with makes these sorts of attractions to diagnoses very appealing. I once hung out a lot with a class of masters students in experimental

Once you understand the math, continuous functions are much simpler than discrete maths (the CS-y things like how many strings with such and such a property are there, or how many ways can you program a Turing machine to take a long time bu

Conserved quantities arise when there is a symmetry in the laws of physics - energy conservation in Newtonian mechanics is basically a reflection of the observed fact that the laws of physics are the same in the past, present and (and one g

Time does move on, but not necessarily for good reasons. TCL is the best way to embed programmability into C or C++ code; Oousterhout’s writings on modularity and composability explain why this is so useful to those that lack the experience

hmmmm. I do like integration tests, but I often tell people the art of modern software is to make reliable systems on top of unreliable components. And the integration tests should 100% include times when the network flakes out and drops 1&

You can say generate a c program that uses gcc 128 bit floats and systematically generates all quadratic roots in order of the max size of their minimal polynomial coefficients, and then sort them and calculate the distribution of the inter

Yeah. I use it for analytics/dataviz stuff (which involves a lot of python to run spark jobs, glue different APis to get some extra column of data, making png or svg pictures,, making D3 based web sites in html and JavaScript). That al

As above, a few relatively isolated groups has no bearing on the truth of the proposition that all members fall into a small number of distinct groups with large numbers of members. If you map out the reproductive connections betweeen these

That is one relatively isolated group. The existence of small isolated groups does not mean the whole species has a small number of distinct subgroups. The smallness here is intended to apply to the number of groups, with the size of the gr

What there isn't is a small number of distinct subgroups that are more related to each other than to the other subgroups.
