This brought clarity to the headline for me. Hope it helps others before clicking.
I view it as such: do you believe we have achieved peak efficiency with regards to production of goods and providing services? If not, there’s room for the economy to grow.

I am not an economist though, this is just my layman’s view.
That’s about a set of specific, known “circuit-breakers”. They shut down trading at the actual exchange, not “ask trading places“ to do so.
That's an interesting comparison.

On one hand, it feels similar, especially if the Command class is "sealed".

On the other hand, it feels like completely the opposite since the command classes contain the code they execute and act like lambdas.

I guess you could apply a visitor pattern on top of the command pattern to make it truly like defunctionalization. I hope nobody actually does this.
Not sure why this is being downvoted. This is generally correct:

It's a nasty virus, but this isn't the Spanish Flu devastating the post-WW1 landscape. It is absolutely going to screw up productions schedules and messing with the supply chain. Turns out if millions of people have to miss work the economy suffers, go figure.
The Navy decided to punish Kearns after he had transferred from the ship, not while on mission.

"A sailor drowned after being thrown into the sea when an 11-meter rigid hull inflatable boat (RHIB) flipped while being lowered into the water from amphibious transport dock USS San Antonio (LPD-17) on the first-in-class ship’s initial deployment. At the time, San Antonio was operating in the Gulf of Aden.

Ship commander Cmdr. Eric Cash received a letter of reprimand. The amphib’s executive officer, Lt. Cmdr. Sean Kearns, was found not guilty of negligence. Kearns had transferred from the ship when the Navy decided to levy a punishment. Instead of accepting non-judicial punishment, Kearns opted to fight a single charge of negligence in a military court. During the trial, according to news reports, his lawyers presented information detailing how, at the time of the incident, San Antonio remained an unfinished vessel with thousands of faulty welds, engine trouble and only a portion of the standard technical manuals typically found onboard. Kearns’ promotion to commander, which had been delayed pending the trial, took effect after the verdict."

"...if you started..."

That's a big if. I haven't done the math yet, but I'll bet that the outside rim of at least one of the gears would have to be started moving faster than the speed of light. I'm not sure how you would do that.

The gear just before the first gear at light speed would have the outside rim moving at about 100th of the speed of light. It would take quite a bit of energy to do that.

(Others have pointed out that at speeds well before the speed of light, some of the gears would melt. I'm ignoring that.)

Immediately yes, it will keep them in gear, but it will have no consequence because the output would come forcibly delayed, so the result will come not so immediately. Hence being anxious has no payout and being cool does.

Wouldn't be that with time, the next generation of traders for example, they will relax more when things feel bearish and put the "normal gear" when it feels bullish?
That was coined for investment capital that comes with a cost. E.g. (in its simplest) borrowing money to trade with, and then having to make regular payments to maintain your positions.

Assuming you have no pressing needs for your invested capital (e.g. most retail investors), the market cannot actually stay irrational longer than you can remain solvent.
Producing human tissue in space
I love that movie. There was a time, back during HS, that I could recite every word while it played. I still randomly quote lines from it.
> Their experiments have shown that the spike protein binds to a receptor on human cells — known as angiotensin-converting enzyme 2 (ACE2) — at least ten times more tightly than does the spike protein in the SARS virus. Veesler’s team has also found this, which suggests that the receptor is another potential target for vaccines or therapies. For example, a drug that blocks the receptor might make it harder for coronavirus to enter cells.

First, let me say that although the government doesn't formally recognize me as a doctor, I watch a lot of medical stuff on TikTok so I'm basically getting my MD 7 seconds at a time.

That aside, this seems dubious to me; if anything it's likely better to take ACE inhibitors now so that your body makes more ACE2 receptors before you get the virus. One of the ways the virus kills people is by detroying their ACE2 receptors, which your lung cells need in order to function. Downregulating them is unlikely to prevent the virus from getting into your cells, rather it will just leave your cells with less healthy ones left over after the virus destroys the ones it uses to enter your cells.

As evidence from this epidemic, smoking cigarettes upregulates your ACE2 receptors, and smokers are less likely to get serious illness from COVID-19. Of course if they do get seriously ill then they're more likely to die, but this is probably just because of the lung damage caused by smoking. At the very least it seems irresponsible to put out a statement like this without saying that all the available evidence currently points the opposite way, as does the evidence from the SARS epidemic.
I've seen stuff like that back in the early- to mid-2000s. It seems, of course, that most of such ‘multimedia programs’ were educational packages for kids.

The market makers and exchanges stop executing orders because a series of circuit-breakers fired (set by the regulating organizations).

Robinhood and other brokers don't execute any trades, they just forward orders from users to their exchange partners and show up to date quotes. They have a much easier load to bear than actual exchanges.

They make more money when trading volume is high. What they can't afford is losing customers to either competitors or customers realizing day trading is a bad idea.

Yes, I use it heavily. The further back in time I go, the more valuable the revision history is.

Where I work, we use it primarily as part of maintenance. Looking through what changes have been made to a section of code over time very often gives insight into what is causing a current malfunction -- sometimes it even lets you spot the problem almost immediately.

We also use it as part of development and bug tracking. All code changes are tracked by revision number. Even there, being able to look up even antique history can be very useful.
Using outside investment to buy back shares seems more than a little silly. Seems like acknowledging that the investor made a mistake, since you have no use for additional capital.
Well, no, it wouldn't take any extra precision. If anything, the current setup takes more precision as you have to keep all servos in sync or it'll be pushing one servo against the others. Right now you could unbolt one of the 4 servos that are on it and it would still work just fine. You wouldn't need to reprogram anything, just having 3 working servos and one completely disconnected would still keep it in the exact same position.

When people sell stocks on RH (or anywhere else) it’s not the broker paying the sales rate. So you’re alleging something like RH having fraudulently sold customers’ stock before?

And the market was moving the other way when RH also shut down last week. This would be the only broker in history that had its system set up in a way where they suffer with any trade.
Fantastic article. I didn't know about this FP terminology but this seems to be a common, general concept.

While reading it immediately reminded me of:

(1) re-frame (ClojureScript) and Redux (JavaScript), which are both web-frontend libraries for managing state and event handling. Browser events dispatch plain, serializable data instead of invoking behaviour directly, which are in practice tagged union types, kind of similar to the provided examples? (I'm not very familiar with the syntax in the article).

(2) it seems to be a common idiom in Rust to move branching logic into pattern matching and enumerations. So defunctionalisation is applicable here and is likely very common to refine Result types and defer execution.

(3) as user edflsafoiewq mentioned this is strongly related to the OO Command Pattern
> I am forever grateful to past engineers for outlining WHY they made their changes, and not WHAT the changes were per se.

Oh, so much this! The same applies to in-code comments. If your revision notes (or your code comments) are only telling me what I can plainly read in the code, then they're utterly pointless. Tell me what I can't read in the code: the "why"s, as well as potential consequences and "gotchas" the changes may present.

IF: you believe in the long term future of the USA.

THEN: dollar-cost-average into the market. Put a fixed amount to work every month. This has been a terrific strategy over the last 50 years or more.

But, caution, you probably don't want to buy a few shares per month of a stock or an ETF in a taxable account. That's because each transaction is a separate taxable event when you go to sell. It would be a nightmare for you to track this yourself. I have no idea how well RobinHood tracks that for you.

If you are investing in an IRA then no worry. The transactions aren't taxable. Of course an IRA has its own problems. Outside of an IRA long-term capital gains are taxed at a lower rate than ordinary income. But when you withdraw funds from an IRA you are taxed at the higher rate.

A Roth IRA doesn't have those tax disadvantages. I've seen a lot of press lately on this issue. For example, in Oregon, the state itself is promoting Roth IRA investing for the "little people":

If Apple moves to a full ARM line-up, they will need to copy AMD's chiplet strategy.

As Apple understands economies of scale, they will need an architecture that will enable them to cheaply mass-produce millions of chiplets to combine them into low, medium and high-end cpus to suit their different use-cases.

Just like AMD is doing now.

There is no way Apple can create a monolithic Mac Pro-level cpu at low volume for a profit.

It might be easier to just go AMD with the whole Mac line-up. Requires only a little adaptation on OS level and will give users less nuisance trying to run their old apps.

In addition, they will gain performant GPUs as a bonus.

You are making a fundamental mistake with your assumption that there is a clear distinction between laypeople and experts in the stock-market, there isn't. Money managers, mutual fund managers and hedge funds managers make terrible mistakes and lose money all the time, and are usually the 1st to panic. So, there is no such thing as an "expert" in the stock market.

Hah! This is funny in all sorts of ways. Supposed "activist" investors settling for a quick ransom. Twitter paying the ransom by taking money from possibly worse people. Twitter paying $2 bn in ransom for Jack, the guy who is at best a half-time CEO, and who has presided over a mix of stagnation and deck-chair rearrangement. And of course the online panic that this was going to be a Trump-allied guy's way of dominating Twitter when it was just another cash grab.

In some ways, Jack is the perfect CEO for Twitter. Twitter is a network-effect business. People are on Twitter because people are on Twitter. The main thing to do with those is to not fuck them up. Jack's distraction, disengagement, and dithering are a perfect match for that. Every time something blows up into an actual PR problem, he promises to listen and think and do better, without every promising anything specific.

But for those of us who think Twitter could be something more, this is all just depressing. They could have spent $2 billion on something useful. Heck, they could have just given each active user $7. And they certainly could have got a CEO with vision and some managerial competence.
Bad idea. You would be just rolling heads of people who just learnt a valuable lesson in high throughput services. Keep them around, they'll get better than hiring someone else who will have to spend more time learning the same lesson.
Business Adventures has a similar anecdote, referring to the 1962 crash:

> "Other firms were less fortunate, and in a number of them confusion gained the upper hand so thoroughly that some brokers, tired of trying in vain to get the latest quotations on stocks or to reach their partners on the Exchange floor, are said to have simply thrown up their hands and gone out for a drink. Such unprofessional behavior may have saved their customers a great deal of money."
