Thermal masses are a super cool way (ha!) to store energy, and I'm surprised they don't get more attention, both in the media, and in terms of research / investment. Heating and co…

the shady part was that they charged him for a full year after he forgot to cancel, despite quoting the price on a monthly basis when he signed up. (Also, "free" auto-renew trials …

Huh, interesting. I read the whole thing and understood at least half of it ;). Are the damages primarily thermal? I couldn't figure it out from that report, although it seemed to …

Yes, but aluminium smelting has certain constraints - namely, the molten metal cannot solidify[1]. This restricts your ability to quickly spin up and down smelters, but they are st…

NAT has not solved the IP address problem, it has merely postponed it slightly. Multi-level NATs are a hell far beyond the single-level NATs that most consumers see (and single-lev…

This is at best a tangential point. If the wind farm is 114MW with a 10% capacity factor, his point is still correct. Yes, they still rely on coal and natural gas to smooth the loa…

Example: https://github.com/urbit/urbit/blob/master/noun/vortex.c#L23... I can confirm this is roughly what the intentional source code looked like. Personally I found it a huge pa…

NO. Do not buy factorio. You will lose sleep. You will lose your job. You will sell your children just for a few more speed modules. The first time I played factorio I played for 2…

Where are you getting $15,000 for the powerwall? It's $5,500 for 13.5kWh, which should be enough for nighttime loads in many houses (but may require some inconveniences, like not r…

Out of reach for your local dentist? Huh? Dentists make more than most people here, $159k/yr average[1]. Software developers make a little over half that on average, depending on w…

VGA is still the most common connector type I see on projectors and in conference rooms. It's being slowly replaced by HDMI, they might be about even now. Ethernet is still the pre…

You can do both. My point is that most of the ports and features they removed really cost nothing in terms of weight, and so aren't really engineering tradeoffs in a sense, but rat…

By perfectly fine, do you mean: - Wifi is flaky (ier than on windows) - Battery life is shit (ier than on windows) - Sleep mode has one of the following problems * Does not properl…

Fallacy of the excluded middle. They can do something more than Apple (i.e. not just USB-C ports), but less than others. The Apple design doesn't end up being small or light, becau…

I'm not convinced having fewer children will help anything and I wish people would stop repeating this. People emit very few greenhouse gasses as a virtue of their existence, the e…

Well, I guess it all depends on what you mean by do poorly in life. High school valedictorians and child prodigies (especially the former) are disproportionately likely to hold pos…

Actually, this is a good point. Uber subsidizes fares ~20% or so currently. Assuming they didn't used to do this, the payout to drivers seems like it would be about the same: 3.75 …

Well, a flight from SFO to LAX is $70 if you book at least a couple weeks in advance. If you assume parity for the ticket price, you need to sell an average of 100,000 tickers/day.…

It does come up? In the case of pensions and royalties, it is wealth from prior work, so it's not really in the same category morally (for a culture that believes in the virtue of …

The average new vehicle purchased in the United States is $33,560[0]. The Tesla Model 3 is $35,000, PLUS $7,500 in government tax credit[1]. This puts the effective cost at $27,500…

That does not match the scientific consensus [1]. You'll have to do better than a single study, summarized in a Forbes article, if you want to make that claim. [1] https://en.wikip…

Zim[0] (open source) has a lot of these features. It saves your notes as plain markdown files, but has a WYSIWYG editor. You can link between notes. Add pictures, formatting, etc. …

"multi-story" => "two stories tall maximum, and half of ground space is parking lot" Places like Paris are entirely (or nearly entirely) 4-5 stories tall, with no parking lots. Thi…

You mean NaN != NaN. null == null is true, and null != null is false. NaN != NaN is surprising, but is not unique to JavaScript. As far as I know, this is the case in every languag…

You can install adobe reader on Linux. On Ubuntu it's acroread from package adobereader-enu. Although sometimes you can use Chrome (or evince, or okular), occasionally Adobe Reader…
