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 cooling accounts for somewhere around half(!) o

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 like this without refunds are by themselves shady

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 somewhat hint that they were. I.e. if you could keep th

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 still potentially a very useful part of an energy smoothing 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-level NATs already cause all sorts of problems for even moderat

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 load, but his point was that by subsidizing the wind power, the

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 24 hours straight, and I am not normally someone who finds

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 running the dryer at night). You are right that it does

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 which sub occupation they work in. [2]. [1] https:&#x2F

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 premier PHY layer for people who want their shit to work.

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 rather design tradeoffs (i.e. thinner). In the feature&#x2

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, because to actually use it you need a plethora of connecto

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 extreme majority of them are emitted by lifestyle choi

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 positions of societal power. Just read the bio of any president

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 / 0.8 => 4.6875 (vs $4.90 originally) The per

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. With 100 passengers per car and 10 cars per train, you

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 work). Social security and inherited wealth definately

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. The Honda Civic, widely considered a cheap car, is $20,415

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.wikipedia.org/wiki/Passive_smoking

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 language, and is mandated by the IEEE 754 specification. However, i

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 is the only one that can fill forms properly.

I agree in principle, but given the huge proportion of energy which comes from fossil fuels, a carbon tax would have to be huge (and hence unpopular) if it were to match the market competitiveness of subsidies. That is, to subsidize solar

Of course, you could have a separate pull-out track for train stations, and interleave the trains. Then you would be able to double your utilization :). I can't really think of any reason why one technology is inherently higher-capacit

That may be true, but is irrelevant. Mathematics is not patentable either, and there are many "significantly new" innovations there. The position of whether software should be patentable depends mostly if you think of it like math

I don't know, I can't see any way that the read: protocol is any more vulnerable than the file: protocol (standard on all browsers), other than the fact that the code is probably less battle-tested.
