> But really, whether anyone believes this can be viewed through a very different lens: multiple times in the past week, US exchanges have ceased trading due to automatic circuit breakers from 7% drops in the market. Surely if the market is all knowing we shouldn't trigger these mechanisms and instead just let the invisible perfect hand let people sell stocks freely.

Yes, you're basically right despite intending to be sarcastic. The circuit breakers are stupid and there's no real good reason for them to exist. Levine:

> The basic idea of stock-market circuit breakers is, like, some news happens, and the market reacts precipitously, and stocks fall 7%, and the market gets turned off for 15 minutes so that everyone can have some time to think and digest the news and see if they want to buy. On an average Tuesday afternoon, not everyone who might want to buy stocks is watching the market every minute. The computers are, sure, but some long-term investors are busy doing other things, reading 10-Ks or meeting with executives or whatever. Someone needs to call them up and say “hey not sure if you noticed but stocks are cheap now, you should buy some.”

> But you generally want to do this sort of thing through mechanical bright-line rules, and occasionally those rules get applied in kind of weird circumstances. The market did not fall 7% by 9:34 a.m. today because of shocking news that came out at 9:32! Investors had all weekend to ponder coronavirus news, and all of Sunday to ponder oil-price news, and they pondered it at their leisure, and futures traded limit-down, and then the stock market opened and investors applied their weekend’s worth of pondering to the market, with the result that the market shut down four minutes later. A weekend of pondering, four minutes of trading, 15 more minutes of pondering. I am not sure what you learned in the 15 minutes that you didn’t learn over the weekend.

Back to you:

> Nor is anyone questioning why it was suddenly urgent that the government put $USD1.5 trillion of liquidity into the market.

The government didn't do that. It loaned $1.5T over a very short term to banks. It was not targeted at the stock market and had no impact there.
None of those quotes say they aim to create herd immunity. They just say you won't get herd immunity until about 60% are infected. There's a difference.

This is a bit too cute by half, especially considering that leading UK politicians have themselves cited "herd immunity" as the reason to do what they're doing.

Your rephrasing sounds reasonable, but I'm not sure what it concretely means, particularly how it differs from every other country's approach. It's vague enough that you could pretty much say the same thing about everything from China's to Singapore's to the United States' approach.
They actually said that? That's some next level fuck-it-I-don-t-want-to-be-in-charge-anymore attitude. Wow. Where's Churchill when you need him?

> Also, the Chinese Party is what caused this mess to begin with, by allowing this virus to spread all around the world.

So did Italy, and they even got a head start in knowledge about the virus of about a month. Yet, the majority of cases here in Germany can be traced back to Italy, and not directly to China.

It's depressing how every country still tries their best to ignore their own failings and defaults to "well China should have stopped it right in the beginning"

I am absolutely sure that things would have been at least as bad if not worse, had this virus originated in Italy. Or Germany, or pretty much anywhere else.

What's surprising about eqn, dc, and egrep? I'm using the latter two all the time, and have used eqn (+troff/groff and even tbl and pic) in the 1990's for manuals and as late as (early) 2000's to typeset math-heavy course material. Not nearly as feature-rich as TeX/LaTeX, but much more approachable for casual math, with DSLs for typesetting equations, tables, and diagrams/graphs. I was delighted to see that GNU had a full suite of roff/troff drop-in replacements (which I later learned was implemented by James Clark, of SGML and, recently, Ballerina fame).
Urban tree planting is great but there must be a better way of planting trees along pavements.

Everywhere they have been planted the roots have torn up the pavements sometimes causing them to mound over the roots which looks really unsightly and is often a trip hazard. Also on some pavements the trees cause bottlenecks because its too narrow for two people to pass eachother.
The strategy of all countries is to flatten the curve to enable their respective health services to cope. My concern is that the U.K. is now proposing isolation for the over 70s “within weeks”: this demographic has been shown to be at serious risk as of now, when looking at the experiences of China, Italy and Spain. Further, in the UK, testing is only now being carried out on cases serious enough to hospitalize, so I do not understand how the UK government can have confidence in its data as to the spread of the virus.

It works similar with HD wallet in bitcoin or ethereum.
In HD wallet, you can derive accounts for many crypto currencies from one seed password which is what master password in lesspass does.

The counters in lesspass, can be used to derive another password for the same website, if one want to change the password for the website.

HD wallet also has the similar functionality.
If you want to change the bitcoin address, just derive another account from the seed password.

And the solution to keep the seed password of HD wallet safe can also work with lesspass. such as [OpenSK][1].

Absolutely. That was the goal. If I didn't like it we could pop it out in a minute and it won't hurt. So no harm in having it done.

I am glad they were aggressive. I would have died a painful death without it.

When the ENT guy said I would probably need a feeding tube I was thinking a thing that would go down my throat. And I was not thrilled about that. Right after the ENT guy I had to see the Radiologist and he was banging on more about the tube.

I still thought it was a down the throat tube. But my sister had google imaged searched g-tubes and showed me on the ride home. Tube in the stomach. No big deal. As long as it wasn't a tube down my throat. Horrible.. But significantly less bad than I had imagined.

I would be dead without the tube. So if anyone else has the same problem you should really get it.

I have to get the tube replaced every ~4 months. Last time I talked to a guy that used to work as a radiation tech at a different hospital. He said they just didn't do radiation on neck people unless they get the tube. Since they will die anyway and it is expensive.

salt = (

)

It’s not ideal for “myusername” on “example.co”, “yusername” on “example.com”, and “yusernam” on “example.com” with counter 225 to produce the same password. Maybe it never affects anyone, but it’s so easily avoided there’s no reason to make this a hazard.

`_insert_string_pseudo_randomly` seems overcomplicated compared to just putting `string` at the end, too.
It is possible to have a stance on something, choose to act on it and still not judge others for not behaving in the same way. You do this by acknowledging that you still may be the one with the "wrong" stance (whatever that means) and by having compassion for others that may not have had the same insights you did.
When people dislike a certain government or person, they jump to the worst conclusions about them rather quickly. This is extremely dangerous. Imagine a sensitive situation develops where there's weak evidence the victim of your dislike did something that might endanger you or your country... if you immediately jump to conclusions, which you are very likely to do as this thread shows, then the situation would easily develop into a confrontation... this is not hypothetical. With Americans and Chinese (and Russians, Iranians) coming face-to-face in more and more sensitive situations around the world, it's only a matter of time until the mutual distrust will cause one side to pull the trigger under unreasonable circumstances.
This flatten the curve stuff kinda presupposes that we have more than zero capacity as things stand _today_.
I argue that COM "died" when .NET rose in reference to the COM ecosystem because prior to the release of .NET on Windows most non-Java developers were writing in either VB6/Delphi or C/C++ for their desktop applications.

VB6 and C++ (specifically, Microsoft VisualC++'s __declspec-punctuated dialect at least) were both intimately connected to COM with their respective compilers have built-in support for DOM/DCOM/etc (e.g. VC processing IDL files and generating TLB files, while the VB6 compiler seemingly reads-in TLB files natively - and can generate its own too) - and all major components for Windows desktop development (such as ADODB for OLE and ODBC database access, the Macromedia Flash player, OLE objects in general, and VB-ecosystem "components" like charting widgets and new styles of buttons were all done using COM - which means programs written in VB6 running in the VB runtime could use the same GUI components and platform feature libraries as C/C++ code running in its own world - that is cool!

While .NET is fully compatible with COM - the ecosystem isn't the same: WinForms and WPF GUI components written for .NET now cannot be used by VB6 forms or C/C++ windows (at least not without hosting .NET in-process and then facing additional issues integrating your Win32/User32 GUI with a WinForms hosting surface) - while hosting COM GUI components in WinForms is straightforward and just like VB6, hosting a COM GUI component in a WPF environment is very, very painful (google "wpf airspace" to see why this is a bad problem).

Additionally, consuming COM from .NET (even VB.NET) isn't as easy or as straightforward as it is with VB6 either - as you have to contend with the ISA of your .NET process (e.g. you can't load 32-bit COM components into an x64 .NET process).

I feel the amount of third-party software on Windows that offered COM automation has dwindled in recent years because of those reasons.

>Why not?

In addition to major airports we also have many minor ones and private airfields. There are 120 commercial ports, and many, many more smaller docks, quays and marinas. We have many islands and remote coastal communities that rely on these for essential supplies and no systematic way to monitor them all. Even then, sealing ourselves completely would have to include stopping goods because goods are carried by people.

Also we now know the virus can survive on cardboard for up to 9 days. We don't have 9 days worth of supplies of everything in the country and don'y have a tracking system for every shipment in or out. We know from the Brexit analysis that we can't track goods enough to tax them, so clearly we can't do the same for medical reasons.

Finally, even if such a lockdown were practically feasible and we developed the logistical and administrative capacity to do it overnight, which we can't, it would destroy our economy. That would inflict massive hardship, particularly on the old and vulnerable, exactly the people we most need to protect. Hardship and poverty kills people, and shutting down all trade and commerce until we have a vaccine, which could be several years or even indefinitely, would take us back to the stone age. It would be far, far worse even than during World War 2, and that's how severe it would have to be to prevent the virus getting in, not just for months but probably for one or more years.

Anyway thats a fantasy, we just don't have the logistical or administrative apparatus to do it fast enough for it to matter.

> The syntax diagnostics from the compiler made by Sue Graham's group at Berkeley were the mmost helpful I have ever seen--and they were generated automatically. At a syntax error the compiler would suggest a token that could be inserted that would allow parsing to proceed further. No attempt was made to explain what was wrong.

On the surface it sounds a lot like it would produce error messages like “expected ‘;’” that most beginner programmers come to hate: was it any better than this, or was that the extent of its intelligence and everything else at the time was even worse?

Some people have a psychological or emotional reaction to code, similar to the way others do to poetry or prose, and sometimes the shape and structure of code gives people a sense of order and centeredness, in a similar way to OCD. The relative simplicity of Lisp compared to other languages probably makes these effects more acute.

I don't know if that's necessarily a trait of the paradigm or of some of its adherents. I've felt that same calming effect but with other languages - and honestly I've found lisp code to be masochistically terse and opaque a lot of the time, although I've only messed with Arc and dabbled with Clojure and Racket. I guess that just means I haven't found enlightenment yet.

How to fight the coronavirus SARS-CoV-2 and its disease, Covid-19
It's not just about your health or your life. This is what R0 means - even if you end up fine after getting the disease, you're going to transmit it to other people who may end up dying because of you.

In other words, it's also your liberty vs other people's lives.

Are you going to be the grandson who kills his grandma? Or the employee who kills the CEO? Or the Trump supporter who ends up helping elect Biden?
It is a theoretical solution. That also could backfire fiercely. The more it spreads, the more likely it is to mutate. And not all mutations will be equals. Plus it might make producing a vaccine more complex.

Could also work. Unexplored territory, the truth is we don't know.

Dan Ariely's MOOC on Irrational Behavior (coursera) remains my favorite online course and one of the best overall.

The content was engaging. It included guest talks. The course didn't shy from hard work, including dozens of required and recommended papers. The curated papers were my favorite part. The course exposed me to an entire ecosystem that I was unaware of.
Too many MOOCs are watered down but this one was just right.

My best advice is to create a course that management will resent open sourcing because it is so valuable. Demand autonomy and use it create a legacy.

Herd immunity doesn't happen for Ebola because it's not that infectious compared to covid19. Ebola spreads when an infected person coughs up infected blood over someone. That's pretty easy to contain - people don't walk around spreading Ebola with no symptoms.

Herd immunity in this case isn't something you choose to cultivate or not. With such an infectious disease you're going to get it sooner or later; that's the UK's point. Trying to wipe it out through self isolation won't be globally 100% effective and if it's not it'll just come back. Ultimately only the population carrying lots of antibodies will end transmission for good.

Symbolics offered for the Lisp Machines various programming languages: C, Pascal, Fortran and Prolog. They also resold a certified ADA system.

The C, Pascal and Fortran was based on a common substrate and they were all written in Lisp. Editing was done in Zmacs with syntax editor support. One could incrementally develop code in these languages and call them from Lisp.

For example the Pascal version of TeX was compiled and distributed with Symbolics Pascal and the C-written X11 window server was compiled and distributed with Symbolics C.

The Symbolics Genera demo by Kalman Reti showed a bit of the integration of C and Lisp code: https://www.youtube.com/watch?v=o4-YnLpLgtk
He used a C-based JPEG library in the video showing the Symbolics Lisp Machine system.

There were also various programming languages and development systems available. On top of Lisp there were various extensive development environments available: KEE, ART, Knowledge Craft - combining programming with objects, rules, logic, ... Even the Nexpert Object system was initially developed on a Lisp Machine.

One commercial system initially developed for software maintenance, software porting and refactoring is REFINE. It is still available on current machines. Targets were various assemblers, COBOL, Mainframe languages, ...
