I have a flat, foam roof, painted white. It really does work to keep the house cool, although the flat roof geometry would be problematic in climates with more precipitation. I suspect roof paint will be much less important in coming decad

Mark Rober had a nice video on this robot. To me, the coolest part was the 'refill station' they built to load dominoes into the robot. https://www.youtube.com/watch?v=8HEfIJlcFbs One critique on the design is th

A recruiter from a prominent SF / Silicon Valley tech headhunting firm once told me that 40 is the cutoff for individual contributors. As a counterpoint, I know plenty of over-40 (and older!) wise software engineers working for places

I'd argue that greenwashing is, indeed, misinformation. That is, it is misleading to categorize a company like Shell as an eco-friendly one. https://www.ethicalconsumer.org/transport-travel/what-greenw... I'

Um, no. Patriotism doesn't equal support for wasteful government programs, and criticism of one's government doesn't equal support for another country's government. Understanding that is part of the cultural 'high

If you're going to be spending billions of dollars, would you rather have a working ship afterwards, or not? Accountability DOES matter.

You're right - I was definitely thinking about the Zumwalt's cannon!

The criticism in the article seems misplaced to me - it falls victim to the sunk cost fallacy. These ships were problematic from the beginning. I remember them being commissioned without a working gun, alongside reports of ship-wide comput

In the US they are limited to 20mph, unless you get the 'speed' version, in which case they are limited to 28mph and technically forbidden from most bike trails. 20mph is a pretty decent clip for a (manual) bicyclist, but 28mph is

These things are still a bit far outside the mainstream, but if anyone hasn't tried an ebike yet, I highly encourage it! It really is magic mobility, with the free feeling of being on a bike, without the sweat or the necessary fitness

Just curious: are there any Chinese nationals (in China) here in this thread? I want to understand the scope of censorship. What do YOU think?

Pretty awesome! I felt like it was missing an affordance to move a stack of cards at once, though. Perhaps it's a hidden key combination?

It doesn't really matter what language you use at the high level, as long as it is calling a highly-optimized, aggressively-compiled, native-instruction-set kernel for most of the work.

I'd like to recommend "The Bread Baker's Apprentice" as a next-level bread book. Full of recipes, techniques, photos, and history.

Reading the last names of the authors of these publications is refreshing, particularly in contrast to the often nationalistic comments that have peppered discussion of this rover. Maybe the future is brighter than we think!

For what it's worth, I've recently been interviewing candidates who straight-up resigned from their previous employer after facing a "return to work" ultimatum. You can too! I'd like to add that there is a big diff

Anecdotally, I've noticed an uptick in metal-framed house construction in my neck of the woods. So, yes, there are alternatives, even in the US. I doubt this results in lower homebuilding cost all-in, though.

As someone who is (sometimes militantly) pro-customer, I don't think tracking parameters are "war" - they are just a tool used to understand visitor flow, and ideally improve the visitor experience. They are fundamentally fir

I'm surprised at all of the anti-cycling sentiment here. It's really a better mode of transportation than the car, in certain situations. It's healthy, relaxing, good for traffic and the environment, and convenient for short

Honestly, good-old heat pumps work well for most climates. You heat up the ground underneath your house in the summer, and harvest that heat during the winter. That seems a lot more economical than synthesizing methane and hoping it doesn

Turns out we're also mobilizing massively with electricity storage technology, in the form of electric vehicles, so that baseload power requirement should be less of an issue in the future. Density doesn't make sense to me as a lo

It's not just trucks - I was able to get my (pre-cheating-scandal) 2003 VW TDI to belch a cloud of smoke if I idled for a while (over five minutes) then worked it hard (e.g. a freeway onramp). I remember getting honked at by a Prius o

They recently raised $1.9B - that will buy a whole lot of grain silos... and quite a few fancy rocket engines, too.
