A good read, and I agree on your points. Like you, I worked my way through undergrad (including a period in the national guard and active army), and escaped with only a few thousand in debt thanks to that. Masters and PhD were free, but tha

I've thought to myself before that an space sim MMO taking place in the Starcraft universe, if done right, would practically print money. But that's always an extremely easy thing for someone to think who is on the outside and not

Another thing that I'll toss in there (as a math PhD) is that the more advanced a topic is, the harder it is to truly grok it on your own without at least SOME connection to a subject matter expert. A mentor can really help you to unde

I think it's because the deconvolution is a bit tricky (with a few different "knobs" to turn somewhat arbitrarily in the process), and can in some ways be expected to add in more artifacts than it is subtracting.

Well, once a month FWIW. I have a google calendar event with a list of checks that I do now that everything is out of warranty.

I do wish the TPMS tied into the OBD so that I could actually measure it electronically. It doesn't on Hondas, maybe it does on other makes?

It takes barely more time to check that then it does your oil or coolant levels (which should also be looked at about as often). For inflating, one of these is small, really simple and works just fine: https://www.amazon.com&#x2F

Working in this area (and coming from a math background), the biggest issues that I have with most scientific and engineering code are: 1) lack of version control 2) lack of testing Everything else (including the occasional bad language fit

This is something that is designed into pretty much all cubesat/nanosat missions, for exactly this concern. Even the ones deployed from ISS (at around 400km altitude) have decaying orbits. I believe the hard rule is no greater than a 2

During grad school, I found that MATLAB, in particular, lends itself to spaghettification. I can think of a lot of reasons why that is, but the one-function-per-file and single flat directory structure of MATLAB programs is part of it. Lang

It seems to work somewhat well. I bought a set of brake rotors that were 100% great, but a replacement wiper motor that ended up being for the wrong model. I wonder to what degree third party sellers are required to verify fit information.

I would agree that complete and meaningful unit and integration tests are definitely a necessity for a large Python projects. Or really for any software project meant to be maintained.

Do you feel this way due to the dynamically typed nature of the language (and the possibility of having ambiguous interfaces)? I've had pretty good luck with rather large scale python projects, though we've been pretty strict abou

True, but I think a key thing for us is that annual leave (which has a carry-over cap) is accrued separately from sick leave (which has no cap). That is, our annual leave is actual bonafide vacation time. In many workplaces in the U.S., emp

I like having accrued annual leave and sick leave for the exact reason that they are tangible numbers that I can reasonably say I own. If it was "unlimited" as you say, it seems more like the company or team owns them, and your ex

Lots of hills, and will have plenty of ice and snow in a few months. It seems to me like a logical place to test the resilience of a self-driving system against some predictable corner cases.
