> Once at its destination and hooked in, its V12 had to be run at a specific, constant rpm' to generate AC current at 60 hertz, the frequency used by most North American utilities.

I don't think this is exactly right. I'm sure it wasn't consistent either, but few loads really cared too much.

From the article's link, about a different locomotive doing the same thing:

> Conrail actually had a set of standing instructions on how to provide quasi-commercial power from a locomotive. For an SD40-2, you attach to the bus before the diodes. Operating in notch 6 runs the generator at 647 RPM. Since the AR10 is a 10 pole machine, that gives 64.7 Hz power. You could tweak the governor to get it closer to 60 Hz if you really wanted to, but for powering everything but clocks, it's close enough. I think the method for regulating the voltage was to disconnect the load regulator from it's governor-powered vane motor and dialing the voltage in manually. The output is 3 phase power. Max output in notch 6 is about 1000KW. If the avg home draws 2-3 KW on the avg, that'd power several hundred homes.

Recently I recalled an extended-ASCII action game from the era that wasn’t ZZT, but I can’t remember anything else.

Anyone know what I might be thinking of?
Of course!

The observation that one neuron can alter the activity of a nearby one is old as dirt. Emil du Bois-Reymond observed it in the late 19th century, but I don't know of anyone trying to quantify it until Katz and Schmitt (1940) https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1393925/ and Angelique Arvanitaki (1941) https://journals.physiology.org/doi/abs/10.1152/jn.1942.5.2...., who named it. There are some other reports in squid (Ramon & Moore, 1978) https://pubmed.ncbi.nlm.nih.gov/206154/, rat cerebellum (Korn and Axelrad, 1980) https://www.ncbi.nlm.nih.gov/pmc/articles/PMC350252/, and others. This review by Anastassiou et al. (2011) might be a good place to start https://www.nature.com/articles/nn.2727.pdf?origin=ppub or this Scientific American article about a paper by my grad school neighbors (https://www.scientificamerican.com/article/brain-electric-fi...)

In parallel, people have asked whether external electric fields can be used to alter neurons' activity, which is even older: a Roman physician in 46 reportedly cured headaches by applying a live electric fish to patients' heads. The idea of using electricity to improve mental function has waxed and waned ever since, with the most recent peak around ~2015 or so. Terzuolo and Bullock collected some of the first data on this using crayfish axons in 1956 (https://www.pnas.org/content/42/9/687) and subsequent experiments by Deans et al. (2007), Radman et al. (2007-9), Ozen et al. (2010), and Frolich and McCormick (2010) found similar results using in vitro and small animal experiments. In parallel, people went absolutely wild with human studies of transcranial electrical stimulation (TES), a family of techniques including tDCS (w/ direct current) and tACS (alternating current). While some of the results have been exciting, they have not always been reproducible (Horvath et al, 2015ab) and some work suggested that the previous work relied on fields much stronger than those achievable in humans (Voroslakos et al, 2018).

Together with some awesome collaborators, I set up a non-human primate model that let us test tES under conditions that closely match those found in humans: like macaques (and unlike rodents), we have big, convoluted brains in thick bony skulls and comparatively sparse neural networks. We found that tDCS could affect neural circuits (i.e., LFP oscillations) and behavior (Krause et al., 2017) https://www.cell.com/current-biology/pdfExtended/S0960-9822(... and single neurons, even in deep brain areas (Krause, Vieira, et al. 2019) https://www.pnas.org/content/116/12/5747.abstract [0] The fields we used were much weaker than those produced by some parts of the brain itself (~0.3 - 1 V/m vs ~4-8+ V/m), so it suggests that ephaptic mechanisms are probably pretty common.

I'm pretty confident in those results, but--to bring things back to the original topic--our recent experiments suggest that getting tES to do exactly what you want, when and where you want it, will take some cleverness and a lot of simplifying assumptions tend not to hold up.

Look at the description of the issue. It's really less of a bug and more of a feature request, in the sense that the legislature changed the rules for how "earned release credits" could be calculated. All of the details are here: https://corrections.az.gov/sites/default/files/documents/PDF... .

Previously, it seems like there was a single standard, applied universally: 1 day of earned release credit for every 6 days served. The new rules have many more inputs, with lots of caveats: only certain offenses are eligible, and the inmate can not have been convicted of some other types of offenses, and the inmate must have completed some specific courses, and the inmate can't have previously been convicted of certain felonies.

The 2k hours may very well be excessive, and I don't care if it takes 20k hours, it means they should mothball their software and do it manually if that's the case, but just calling it a "bug" is misleading IMO.

Please read the post that I was responding to, which insisted on framing everything in terms of some weird definition of luxury-price morality. It's strange how much of a raw nerve is touched when you point out the absurdity of people's various moral crusades.

In terms of why the actual vendor is or is not raising prices, I have no idea, neither is it important. I was making a counter argument, not lobbying the vendor. They could charge a million dollars or one dollar for their handcrafted pens and there would be zero moral difference between these two prices.
Perhaps this is straying a bit far from the topic at hand, but is it really true that you'd be hard pressed to find a Muslim scholar who considers the worship of Jesus Christ as God to be tantamount to the worship of a false god? I really don't know one way or the other, but I find this a bit hard to believe. I understand one might try to rescue the position by pointing out that those worshippers of Christ do so while explicitly identifying Him as one with the God of Abraham. However, I also vaguely recall an episode in the Torah where the Israelites decide to worship an idol as a substitute for God (wait, wasn't this why Moses destroyed the tablets containing the ten commandments?), and it seems to me an obvious parallel for one who believes Christ to be a mere prophet.

To come full circle, this almost lends credence to the belief called out (as false) in the article, that the Muslims worship Mohammed; because it seems as though the line between the worship of Allah and the worship of his prophets is somewhat blurred. But presumably this does not at all follow the lines of actual contemporary Muslim theology :).
Not really. Some people do that. Most just leave it on auto-contribute which means you'd get paid per view.

It's also not terribly hard to get verified so you get paid. As long as someone is reasonably familiar with technology, I think it'd be pretty easy for them. Haven't tried it for myself though (but the guide is up there so you can see it for yourself if your curious).

What are those features out of reach of tree-sitter? I can see that you theoretically want something that's optimized for parsing well-formed code all at once, rather than potentially malformed code incrementally, but what trade-offs does tree-sitter make in practice that limit its potential for your use case? On the face of it, it seems to me like tree-sitter could server as a perfectly fine building block for generating LSIF or whatever from a code file.

I truly believe this will prove to be a bubble but I also think there is a lot of hubris in calling something a bubble before it pops.

Is Amazon a bubble? Is Netflix a bubble? Is bitcoin a bubble? Is Uber a bubble? Is the dollar a bubble? Are near zero yield bonds a bubble? Even if you agree on the general premise of the everything bubble, most people would disagree on the specifics and it is at least within possibility that this bubble melts up and never pops.

So basically, call it a bubble when it bursts, and put your chips on the table until then.

Especially for luxury items, it makes sense to keep the price pretty high and supply limited (like Ferrari).

> uh... no my dude. Whether a company buys back the shares, or issues a cash dividend, warrants, or someone else is willing to pay you more for the same shares, you've obtained what's called a "total return."

You seem to be unaware that different investors have different investment goals.

> What any investor is looking for is a total return, and it doesn't matter in what form.

Yeah, no. Some investors want dividends, some want gains, some are more concerned with security of principle, some optimize for total return. This is taught in finance 101.

> Inflation only sets the benchmark rate for total return.

Inflation creates a margin rate of profit that must be met or a business loses money.

> When a company issues a dividend its stock price drops by the decrease in net asset value of the company once the dividend is issued.

It depends. Sometimes the price goes up because they have shown that they are in a position for the owners to take profit. Sometimes it goes down because shareholders want to reinvest their capital elsewhere and its timely to do this immediately after dividend receipt (because you’re not waiting for the next dividend).

> The difference between an unrealized gain and a dividend is the difference between a "realized" and a "mark-to-market" gain. They have different profiles, and different benefits. For instance, a mark-to-market gain can be rolled forward into different tax years where as a realized gain must be attributed to the current tax year.

I’m glad you understand this. Now based on this, can you see why some investors would prefer dividends and some would prefer capital gains?

> When the principal decreases by 2% per annum and the rich person pays 2% interest and the poor person pays %600 percent, the rich person gets free credit while the poor person pays ~600% per annum. Surely you can see that this is worse for the poor person, even before factoring in that the rich person gets capital gains from asset inflation while the poor person gets real decrease in wages.

Inflation is a small part of the interest rate calculation. Even if inflation were 0% a rich person would pay 0% and a poor person 598%. You've achieved nothing.

> Surely you can see that this is worse for the poor person, even before factoring in that the rich person gets capital gains from asset inflation while the poor person gets real decrease in wages.

Wages have kept pace with inflation, and capital gains tax is a social/fiscal policy matter for Congress, not for Janet Yellen. Try again.

Professional Ethical Hackers
You’d be paying for earnings several years out, for sure. But I think it’s hardly fair to compare to Nikola.

Trevor Milton’s experience prior to starting Nikola was selling home security systems. Lucid’s leadership team features various Tesla, Audi, Ford, VW, etc. veterans. (See page 9: https://www.lucidmotors.com/files/lucid-investor-deck-februa...)

Lucid has finished building a factory that can produce roughly 30k cars per year, expandable to 400k.

They’ve given rides in their launch vehicle to various auto journalists (https://youtu.be/gqSN2QNgO5k).

Their battery pack technology is a component of the Formula E drivetrain system (https://lucidmotors.com/media-room/atieva-powers-season-6-fo...).

This isn’t a “Nikola rolling a non functional truck down a hill” situation. They have a working product.

The car could suck, the company could be overvalued. But I think hard to compare Nikola to Lucid.

EDIT:

I should also add for comparison, that at the time that Tesla IPOed in 2010, it was a 1.7B market cap company. Only ~2450 Roadsters (their only car at the time) would be sold in total. By November 29, 2010 Tesla had not yet sold 1400 cars (https://www.tesla.com/blog/race-champions-2010-motorsport-go...).

Tesla's Fremont factory was opened in October 2010. In other words, when the company went public on June 29th, 2010 you would have been buying into a car company without a factory.

The first Model S wasn't delivered until June 2012 (https://www.tesla.com/blog/tesla-motors-begin-customer-deliv...).

Not to say that Lucid will or won't ever reach Tesla's heights, but assigning a 12B valuation to the company isn't loony. The SPAC price though is a different story.

EDIT 2:

There are some fun short videos of Lucid CEO Peter Rawlinson in the workshop from his Tesla days (https://www.youtube.com/watch?v=TrbOLHW8Pec, https://www.youtube.com/watch?v=8YxHp2ot61Y, https://www.youtube.com/watch?v=NGKqPYvtqXE). It's pretty awe inspiring to see where Tesla and the global EV industry as a whole was in 2011 vs today.
It's easy to create a prototype, the true test of any manufacturer is it's ability to roll these from the factories at scale. How many have they rolled yet?

> I won't avoid Unix-ism when writing code (e.g. I'll probably use fork(2)).

It’s probably fine to not avoid most Unix APIs but fork() is truly an exception here. Fork() is not friendly to any third party library you may use because their state may become invalidated after a fork but the library has no way to know if the process has been forked. This is especially bad if the library uses multi threading. The best way to avoid a random unintended bug later on is to only use fork() when you plan to execve() right after.
> You seem to be unaware that different investors have different investment goals.

No, investors only have one goal: total returns. Anything else makes no sense. After all a stock that issues a $5 dividend and goes down $10 ain't worth investing in, is it?

> Yeah, no. Some investors want dividends, some want gains, some are more concerned with security of principle, some optimize for total return. This is taught in finance 101.

All are gains. At the end the day there's one bucket of money. you're saying it matters how you apportion it, and I'm telling you it does not.

If you hold 100 shares and a company that doesn't issue a dividend, but went up 1%, you can sell 1 share to obtain a 1% dividend. Or you can wait for them to issue a 1% divided and be left with 99% the value. It's a no-op. Same thing. You've failed at basic math here. There's one bucket of money. Dividends don't appear out of thin air.

> It depends. Sometimes the price goes up because they have shown that they are in a position for the owners to take profit. Sometimes it goes down because shareholders want to reinvest their capital elsewhere and its timely to do this immediately after dividend receipt (because you’re not waiting for the next dividend).

No. You are strictly wrong. When a dividend is issued the stock goes down by that amount. [1]

After a stock goes ex-dividend, the share price typically drops by the amount of the dividend paid to reflect the fact that new shareholders are not entitled to that payment.

> I’m glad you understand this. Now based on this, can you see why some investors would prefer dividends and some would prefer capital gains?

Yes, but you have it wrong. Dividends are less valuable because they offer no flexibility in recognition date. Either way they are both treated as capital gains. In fact, I believe, correct me if I'm wrong, dividends are treated as ordinary income. On the other hand if you sell something you've held for 1 year in lieu you'll get long-term capital gains treatment.

> Really now, this is rich. If you think my perspective is that outlandish then you truly have not studied this to any great extent.

I'm an investor. I suggest you revisit ECON-101.
