But even if these magnets were only as powerful as rare earth magnets, the benefits to the environment are huge.

I put together an example of how to run chromium with --headless driven by cucumber/capybara: https://dkastner.github.io/2017/04/21/headless-chrome.html

As another Faraday employee, I'll add that we didn't start right away with deployment. Instead, we used docker to provide a consistent way to test our apps. Once all of our apps we…

A huge payoff that Rust provides vs Ruby or JavaScript is when writing development tools. It saves so much time and trouble to install a binary than to try and get someone to downl…

While it's true there are more sources of plastic other than fossil fuels, the big disadvantage is the extra amount of energy and water needed. I doubt we'll be able to scale alter…

Not only is it made from the lowest-grade oil, but this low grade oil constitutes the majority of all the oil (and near-oil substances) that's left, e.g. tar sands, oil shale.

The $1000 question is what the downside of the curve will look like. Will it be a sharp drop-off or a long plateau and decline? It's looking more like the latter at the moment.

You're going to burn a lot more energy getting to and from the asteroid than what you'd be able to bring back.

I like the colors

I've been using a very similar tool, browserify to do the same thing. The great thing about browserify is it already comes with core node.js library support, as well as an http mod…

Yes, I realize that most of our electricity comes from coal, natural gas, and nuclear. However, that fact doesn't preclude the idea of using solar, wind, tidal, and geothermal ener…

Yes, I know that patent is actually more specific than "driverless car." I was just being snarky.

Prior art: trains. Seriously, though, this is a complete waste of time. Mass transit has been solving the problem of getting people from point A to point B without them having to d…

I read your Hacker News post and was very impressed by your skills. I would like to talk to you about a career opportunity that I'm sure you would find very interesting. Please con…

My new business plan: 1. Abandon the city for the wealthy suburbs 2. Leave the poor behind, defund infrastructure 3. Sell tours and photos of neglect and destruction 4. Profit! Som…

You'll also need plenty of hafnium, titanium, and molybdenum. Not exactly abundant resources. All that just to get a 4% solar->electricity conversion rate. You can put these panels…

I've created a quick fork of tmuxinator (originally used for defining sessions for tmux) to also generate iTerm setup scripts: https://github.com/dkastner/tmuxinator

I forked tmuxinator to generate the appropriate applescript that will set up iTerm according to your tmuxinator config: https://github.com/dkastner/tmuxinator/commit/c96d04d994cd8c…

Here are some great rebuttals to "Just Food:" http://www.grist.org/article/2009-09-08-mcwilliams-locavore-... http://sharonastyk.com/2009/09/11/start-by-asking-the-right-...

I forgot how awesome geometry was. Anyone know of any courses (online) that each geometry through functional languages (or maybe even vice-versa)?

I've found that using function compositions/closures for event handling makes my JS code much more testable and readable: http://numbers.brighterplanet.com/2011/06/10/a-pattern-for…

I think context matters here. The article was discussing GUi word processor usage. When using an app like Pages or Word, the mouse will be faster because keyboard navigation in tho…
