joelwilliamson··on French workers protest plan to increase retirement age
Wasn't the Seattle interurban torn up in the early 1940s? I don't think you can blame that on the boomers.
joelwilliamson··on Ask HN: Why Hasn't the Doomsday Clock Advanced?
The Russians didn't keep the doomsday machine secret to improve its effectiveness. The Russian ambassador says:

"It was to be announced at the Party congress on Monday. As you know, the Premier loves surprises."

You don't want to announce that you are building the machine before it comes online, because that gives the adversary an incentive to strike before it is finished; you want to bring it online and then make the announcement shortly after.

joelwilliamson··on California to hand out $1000 stimulus payments to residents to combat inflation
If printing money doesn't cause any net inflation, then what is your theory about what does cause inflation?
joelwilliamson··on The best apples for apple pie
A family from Costa Rica just moved in down the street from us, and the wife was complaining that the bananas here are terrible compared to her home.
joelwilliamson··on Show HN: I made a website to search for half loaves of bread
I suspect that's mostly because Indian labour is much cheaper. Making a loaf of home-made bread uses about $0.30 CAD of flour, and yeast, salt and water don't add much to the cost.

(Edit:) Also of course anti-competitive behaviour by the bakery cartel drives up prices in Canada.

joelwilliamson··on Redditors are right about the unfairness of the market
In 2019, 84% of the S&P 500, 69% of the S&P MidCap 400 and 53% of the S&P SmallCap 600 paid dividends. I would not characterize dividends as "relatively rare", and I'm curious why you think they are.

joelwilliamson··on Tesla is ordered to turn over Autopilot data to a federal safety agency
Shouldn't the objection be to anything less than Level 4, rather than Level 5? Level 4 requires that the vehicle can safely stop itself and wait for a human to take over when it is faced with a situation it can't handle.

(There's an argument that if you take away the routine parts of driving, humans won't be able to deal with anomalous situations, but that's a different argument than the attentiveness one.)

joelwilliamson··on Dancoland
In the hands of a master like Plato, this style is heuristic; that is, it allows the reader, indeed leads him, to discover things for himself. [...] "A master like Plato," we said - but there is no one "like" Plato. Other philosophers have attempted dialogues - for example, Cicero and Berkeley - but with little success. Their dialogues are flat, dull, almost unreadable. It is a measure of the greatness of Plato that he was able to write philosophical dialogues that, for wit, charm, and profundity are the equal of any books ever produced by anyone, on any subject. Yet it may be a sign of the inappropriateness of this style of philosophizing that no one except Plato has ever been able to handle it effectively.

joelwilliamson··on Pressure-induced high-temperature superconductivity retained at ambient
It doesn't superconduct at 300 K, the metastable phase can survive heating to 300 K and superconducting will resume when cooled back down to 26 K.
joelwilliamson··on Google’s lawyer accidentally made a sensitive document public
Bernanke used it in a speech for the first time in 2002, but it was coined back in 1969 by Milton Friedman.

joelwilliamson··on Ask HN: Why there are so many ads on YouTube?
Just use an adblocker. The only time I see see ads on YouTube are when I'm using someone else's browser.
joelwilliamson··on What used cars tell us about the risk of too much inflation hitting the economy
The Shadowstats methodology is to take BLS CPI and add 3%.

If your theory about what's wrong with CPI is "BLS is subtracting 3% from the true value" that is a useful fix. If you're concerned about the basket of goods they use, or deflators for quality improvements, or substitution effects, or any other technical concern it isn't clear that Shadowstats provides any value.

joelwilliamson··on Report: Tesla is building a giant 100 MW battery in Texas
100 MW for 10 ms is 28 Wh.
joelwilliamson··on Ercot nearly at capacity for Texas power grid
There's no waste heat with resistive heating, but heat pumps use electricity to move heat from outside to inside, and they can add more than 1J of heat using 1J of electricity.
joelwilliamson··on Beej's Guide to Network Programming (1994-2020)
It's useful for any Unix that has BSD sockets, not just Linux.
joelwilliamson··on Access to vocational education can boost income over the long term
Khwarizmi was Persian, not Arabic.
joelwilliamson··on Computer input latency from 1977-2017 (2017)
I think it's Window Animation Scale, Transition Animation Scale and Animation Duration Scale.
joelwilliamson··on It is high time we let go of the Mersenne Twister (2019)
That article was rife with errors. Notably "recall that the seed for a 32-bit random number generator must be a 32-bit number" is quite obviously wrong, the seed size is constrained by the generator's state size, not its output size.
joelwilliamson··on It is high time we let go of the Mersenne Twister (2019)
Rogue is two years older than River Raid and also used procedural generation.
joelwilliamson··on Army wants smaller brigades, stronger divisions and lots of robots
That 10x figure doesn't sound right to me. Between the Taliban and government forces, Wikipedia says there were over 130,000 killed. Have over a million Mexicans died in the drug war?

Otherwise, (as I assume) you are comparing foreigners killed in Afghanistan to Mexicans killed in Mexico, which doesn't seem like a fair comparison.

joelwilliamson··on ‘Cash Is Trash,’ So Let’s Bet $425M on Bitcoin
A buyback is just a way to structure a dividend for better tax treatment. Do stock buybacks and dividends form a larger fraction of corporate earnings now than they did historically?
joelwilliamson··on ‘Cash Is Trash,’ So Let’s Bet $425M on Bitcoin
> The idea of explicitly returning value to investors wasn't common until the 1980s

Dividends were very common pre-1980. What makes you think they weren't?

> I think stock is supposed to be like gold, you invest in the value of gold.

The value of a stock comes from the possibility of capital return from the company. If the company never gives anything to shareholders, the value of a stock is no more than the paper it's printed on.

joelwilliamson··on ‘Cash Is Trash,’ So Let’s Bet $425M on Bitcoin
That's the whole point of a joint stock company. If capital is never returned to investors, why would they invest in the company in the first place?
joelwilliamson··on Why ‘Civilization’ is a political masterpiece
Civ3 and Alpha Centauri both have separate Build Road To... and Build Railroad (or Magtube) To... automation modes.
joelwilliamson··on The end of dispersed camping?
Just an FYI, Algonquin is the third largest Provincial Park in Ontario. The largest is Polar Bear (3x larger than Algonquin), but it is only reachable by air and you need special permission to visit. Wabakimi is also a bit larger than Algonquin and has road and rail access.
joelwilliamson··on China’s Plan to Build the World’s Biggest Supergrid
China is also quite decentralized. The provinces have an enormous amount of power to resist central government demands to do things they don't want to do. Look at how much trouble they are having trying to crack down on highly polluting power and industrial plants. If Beijing wants something, and the provinces don't, it's probably not going to happen.
joelwilliamson··on Climate Change Can Be Stopped by Turning Air into Gasoline
"[The sun] blasts unimaginable quantities of energy into space each instant, and virtually every joule of it is wasted entirely. Incomprehensible riches can be ours if we can but stretch our arms wide enough to dip from this eternal river of wealth."

joelwilliamson··on How to Fall Asleep in Two Minutes or Less
I recently upgraded from an Aura to an Aura ONE, and the backlight is much better. It can be amazingly dim, and at night it uses a hue that has almost no blue light.
joelwilliamson··on The U.S. will impose duties on solar equipment and washing machines made abroad
In 2016, China had 70 GW of installed solar power, compared to 40 GW in the US. They installed another 50 GW in 2017.

China has 320 GW of installed hydro power, compared to 80 in the US.

China had 160 GW of installed wind power in 2016, compared to 80 in the US.

joelwilliamson··on Tradition for Sale: On University Architecture
American universities being fairly conservative architecturally is hardly a new development. Look at how popular faux-Gothic is at any Ivy League school. They are all full of modern buildings trying to look like Oxbridge.
