The discussion around shared e-scooters (and similar micromobility) tends to have a ton of hidden status quo bias. For example, one of the most common complaints about e-scooters is that people leave them all over the place and they clutter

Do you worry about ebike theft? If not, how do you lock it in public?

This paper might be a good starting point. It's mostly about vehicle-vehicle collisions and the higher risks from heavier vehicles, but they discuss pedestrian fatalities a bit. https://www.nber.org/system/files&#x

I'm also shooting on an Olympus M43, several years old. Any suggestions for software tools you've found helpful?

I think your source [1] is directionally correct but very wrong on the numbers. (It's also a decade old, but that doesn't explain these errors.) For example, it says (last sentence) that Americans average 6 tons per person per yea

I don't see that anywhere in the post - was that in a previous version, or somewhere else, or your summary? This is surprising, because the Julia devs have been very careful to maintain backwards compatibility since version 1.0 release

order of magnitude nit: the article mentions 250 gallons of gas, not gas for 250 miles - so roughly 25x worse

With the caveat that I'm approximately as crypto-skeptical as they come, (a) the interview snippet in that video sounds like SBF describing how a hypothetical could work, not his actual business - though it's hard to tell with all

How has Python - almost surely the most successful and widely adopted scientific programming ecosystem - avoided the problems of #2? E.g. Python doesn't have static typing. Is it just that Python is so widely used there's institut

There's something a little strange and subjective about saying "a problem with language X is that third party package Y has a bug." Y != X. If Y is some tiny package that hardly anyone uses or cares about, then bugs in Y don&

Gurobi had excellent speed for us, but we didn't notice a difference between Gurobi and open source tools on final solution quality; all the linear solvers we've tried get to certifiable optimality on our problems, some just faste

At Zoba we use CLP, CBC, NLOpt, and OR-tools. Used to use Gurobi. * CLP/CBC: open source makes deployment and devops easy, which is great. Linear models are nice in that you "know what you're getting." Performance is at

Julia (and the Gadfly package, which it's worth noting is not a standard library or anything like that) have come a long way since 2014. JuMP too. Julia was indeed "not ready" in 2014; it wasn't anywhere near the 1.0 r

You prefer China (presumably here we mean the CCP) to any American corporation, because some American companies have done the moral wrong of sometimes folding to the CCP? Seems a bit inside out.

A heavy car or SUV at 5.6mph has about the same kinetic energy as me on my bike at 28mph (25x weight difference / 5x speed difference). I don't know about you, but I would prefer not to be hit head on by an adult on a bike traveli

Ultimately I do not know whether Oklo and/or their founders know what they're doing, though I hope for the sake of the planet that they do and they succeed. But calling them out for having no nuclear industry experience seems some

Thanks for this explanation. One thing I've never quite grokked: if the debugger ignores breakpoints in compiled mode, how is running in debug compiled mode different than just...running the code normally?

Super agree. I would own and use a menagerie of personal electric vehicles if I weren't worried about death by [someone else's] car. (I mean, my main transportation these days is a mechanical bike, and I still worry about death by

A few months ago I wrote a short Twitter rant about a Boston Globe article that described a pedestrian being struck by a driver really poorly. Thread: https://twitter.com/evanjfields/status/1387131251811831812&#x2F

I wrote a blog post exploring the tradeoffs different geo grid systems make, including H3. The post describes a proof of concept exploring a different part of design-tradeoff space. https://evanfields.github.io/No-Perfect-Ge
