I have been shouting this point (the preferability of distributed, redundant means of production) vs. ( large-hyperoptimized/hyperspecialized, maximally-centralized means of production) for years, but you might as well not even bother. All business/finance centric folk see is redundant waste in the face of a perfectly efficient minimal input consuming industrial monolith that falls down to a stiff breeze and brings everything else down with it.

This very contention played out during the country's founding in the constant friction between the Federalists and anti-Federalists which tended to line up with either a Jeffersonian economic approach vs. a Hamiltonian economic approach which I'm fairly sure had roots in the contrasting philosophies of John Locke and Thomas Hobbes... It probably goes back further, but that's as far as I've traced it.
I've picked up Racket recently after a long while and I'm enjoying it.

Does anyone have recommendations of how to learn to think recursively? Sure, using the language more and more does it, but what about a more general recursion as a problem solving paradigm pattern? I'm enjoying doing recursive code exercises and got into Backtracking problems. Creating things like Sudoku solvers, Knight's Tour grid etc was quite fun. I still can't develop recurrences easily though.

Any books/exercises that people here found helpful?

> Even if it were tiny for a black hole it would be hard to imagine that it would have less mass than our sun.

Planet Nine has a mass five to ten times that of Earth; that's explicitly mentioned in the article.

Such a black hole can't form from the gravitational collapse of a star, but it possibly could have formed in the early universe. That's what the article means by "primordial black hole".

> How small can a black hole be and still qualify as a black hole?

The theoretical lower limit to the mass of a black hole is the Planck mass, which is tiny (about 10^-5 grams).

We have never observed a black hole smaller than several solar masses, so we've never observed one that wasn't formed from the gravitational collapse of a star. Finding one as small as five to ten times the mass of the Earth, if it exists, would be basically impossible if it weren't hypothesized to be somewhere within our own solar system, and even then, as the article says, it's very difficult. So it's quite possible, from that point of view that there could be primordial black holes of that size out there that we haven't seen. The question is how likely theoretically is it that such black holes could have formed in the early universe, and the range of estimates on that is quite wide, since there's a lot we don't understand about the early universe and about how such holes might have formed.

It would be insanely improbable for independent life to have formed separately in such close proximity. The odds of that are entirely dwarfed by the far more likely panspermia scenario.

Words are vulgar because they are overused.

It's the original definition of "vulgar" - "characteristic of or belonging to the masses." Hence, it became taboo for the upper classes to utter vulgarities, because it signaled lack of learning.

Is the charge here really proportional to the crime? As frustrating as it might be to MySpace, it's fairly benign, and it highlighted a vulnerability that could have been far, far worse. Surely those three years without Internet would have been better spent highlighting more vulnerabilities, with the threat of jail time if harm is done again.
It is and it will get corrected. The question is how. The CPI could inflate to match the asset bubble, or the bubble could pop. The first is looking more and more plausible. When either happens, it will be ugly, but if the first scenario plays out, "cash is trash" as Ray Dalio says.
I could say the same for whoever came up with the idea of black on white.
Blot.im does this but with dropbox and its amazing. Since you use word docs instead of g docs the formatting transfers over perfectly. Super easy setup and $20/yr. I’ve been using it for 2 or 3 years and it’s great.

Npzero.com is my blog if you want to see an example. There are much prettier themes you can choose from as well. I have a chrome book so sometimes I write in g docs, export to word, and upload to Dropbox’s webapp and make final adjustments in their online editor. No affiliation, just a great product.

This is what always gets me. People claim to love science but don't listen to it or have a basic understanding of the actual process. We can see it with hot topic issues like the current covid crisis or global warming. People take the easy positions and say because of that that they understand the science. But in reality science is extremely nuanced[0]. It isn't so much the lack of nuance that makes these people harmful, it is that they are adamant that they are well researched.

We make the jokes with anti vax people that just because a baby came out of you doesn't mean a PhD did. Yet, I don't think how many people realize how harmful it is to oversimplify these topics. We can't solve these big complex problems if we make them politicized and just pretend that there is a singular and simple solution to everything. And that everyone that deviates slightly from the accepted dogma is a heretic[1] (which ironically tends to include a significant number of scientists in the field of concern).

[0] As an example, there are many, even here, that think we just need solar and wind and we'll solve global warming.

[1] I say that these are armchair scientists armed with a baseball bat.
Apologies for the pedantry, but whether you're looking at national (US) or international numbers, COVID-19 has killed "only" about as many people as a flu season. ~300k have died from COVID-19 in the world, which matches the WHO's estimate of 290k to 650k per year for the flu, and ~80k in the US almost exactly matches American numbers for the flu a couple of years ago [2]

[1] https://www.who.int/news-room/fact-sheets/detail/influenza-(...

[2] https://www.statnews.com/2018/09/26/cdc-us-flu-deaths-winter...

Moreover, comparing the flu season to "just 4 months" is disingenuous. That's...roughly as long or even longer than what most people consider the flu season.

Of course, this is due to the lockdowns. I'm not trying to make the case that COVID-19 is "just a flu". we'd almost certainly be seeing much worse numbers if people weren't social distancing or whatever. And we're not finished yet.
I would add another factor lots of people overlook: the trend towards index investing. In the past, asset management involved actually analyzing the performance of a business, now it’s just trillions of dollars allocated merely by market cap. Index investing makes everyone QEs bitch - the end game for it is what we’re about to experience.
> Pricing as much as the market will bear is not good for consumers

To be fair, that's how all products are priced in general: production cost defines the lower bound and what customers are willing to pay defines the upper bound, and the goal is to maximize what the customer pays.

Yes but the percentage of positive tests accounts for the increase in testing rates. Positive tests divided by total tests.

If percent positive of all tests is the same as before then the infection rate is not decreasing, or increasing - its constant. That is the case in many areas although some are seeing decreases or increases. E.g. some are increasing (e.g. Maine, South Dakota), some are decreasing (e.g. NYC, NJ), some are constant (e.g. DC/MD/VA have been constantly at 20% positive for the last couple of weeks now).

Most states are looking for a decreasing rate of positive tests for two weeks especially of its the percent positive case is under 10%. Generally under 10% is considered under control or manageable by experts.
Discounting is also a harsh mistress. If your model expected a 10% discount rate but actually achieves -20%, say next year, then it would need to produce 51% just to get back to baseline on the year after that. Early missed returns do hurt disproportionately unless there is an easy way to get back on track.
I run Linux (Arch) on my personal Dell XPS13.
I run Ubuntu 20.04 in a VM at work to do NodeJs/Springboot (backend) development and even in a VM, especially for node, the experience is better than colleagues running bare metal Windows.

Going back to the XPS13 the Linux experience is not perfect.

* the mess with the HiDpi support and font systems. I often go from the laptop docked to a Usb-C hub to using my laptop on my coach. And my external display and laptop screen don't share the same pixel density. And it is a mess to switch from one to the other without hurting my eyes. Fractional scaling is blurry under Wayland or X in Gnome. Also some apps rely on Gtk for font rendering and thus react to GDK_SCALE environment variables but some don't. Some understand the Xft.dpi X server font dpi setting, some don't... I stopped doing fractional scaling of the whole display and just automatically detect which display is connected (thus does not work on both) and change the Gnome font settings

* Worse Battery life. I kept the Windows10 partition just in case and sometimes spend a bit of time on it and I have a much longer battery life on Windows10 doing the same things. On Linux I get 6 to 8 hours, when on Windows it is more between 8 to 10 hours. I think the main reason for that is the lack of off-the-shelf hardware accelerated video decoder in the browsers on Linux (I watch quite a few youtube videos). Yes I know TLP, powertop, etc.

* No driver for the fingerprint reader. It is a shame since the same model is sold by Dell with Ubuntu but the driver is not available. It is something I really like on Windows.

* Worse bluetooth experience. On Windows10, my bluetooth headset or speakers connect instantly, on Linux it takes up to 30 seconds and I usually have to manually force it (completely random)

* More instabilities. Usually after a resume sometimes bluetooth or wifi stop working and I need to reboot (once or twice a week).

* Lack of Wayland compatible apps. (I run Gnome) and some apps do not work and sometimes don't have Wayland equivalent: OBS is buggy on Wayland, polybar (status bar) does not work. I moved back to Xorg but I find it less responsive.

That being said I experimented a bit WSL on Windows10, it is nice but I am still not coming back to Windows 10. I don't like the OS advertising apps that I don't want and WSL feels a bit like a workaround you don't get the full experience, cannot start services, mount filesystems or launch apps with a UI seamlessly.

I’ve been thinking about going the other way a bit recently: having bots consume input from and add their output to a Google Doc.

There are so many processes in most businesses which involve many humans collaborating on templatised documents. Google Docs/Sheets fits into these workflows very well, but there’s often scope for some partial automation in there too - pulling information from databases and outside sources and keeping it in sync, etc. Developing custom web apps for each case is too much effort for too little reward, takes users out of a familiar (and well-liked) interface which updates in real-time, makes you reimplement permission models, etc.

Not something I’ve explored properly yet so I don’t know if the APIs are rich enough to make this easy, but I would really like to give it a look.
If anybody has some relevant experience and wants to collaborate, hit me up! Been kicking around this one for a while now..
Very insightful, hadn't considered that!

You can do this with Emvi [1] too. It works like a headless CMS. I wrote a wiki for a German gaming community [2]. The project is available on GitHub [3] if anyone is interested and can easily be adopted to your own project. The articles fit a blog very well as they don't use pages and therefor are continuous. The API spits out clean HTML.

We don't know how many cases are out there. There is just not enough testing.

We can only count deaths, but even that is tricky since people that were given 30 days to live are being counted as COVID-19 victims if they were infected.

The only way to know what the impact of the virus is/has been, is to compare with deaths from the previous years.

It's rather natural in most of the highly developed countries where people can afford to live separately from non-immediate generations. It's virtually the same in the European country I live in, and in both places elders often treasure the independence that they can have because they've grown up valuing a greater degree of individualism. I'm curious why you think nuclear families have turned out disastrously.

Sure, nvidia is problematic, hence Linuses now famous rant, but that's to be expected, they don't cooperate at all.

I understand it may be the only option for high-end gaming, but in that case one probably doesn't have switchable graphics, which causes the most issues, so X/Xwayland is the one compromise one has to make.

This however does not mean that Linux graphics is a mess in general. I have both Intel and amdgpu machines that work out of the box, no problem. And this does not ever gets asked in relation to macOS, because everyone "knows" nvidia just wasn't a thing there in recent years. So perhaps we should assume nvidia just isn't a thing as well, unless you're willing to put up with crap?

So does Linux and Linux on the desktop work for everybody? No. Does it work as good for a high-end gaming machine as Windows? No. Does Windows work as the most productive fronend/backend/systems OS for programming out there? No. Does Linux? Yeah.

So while they both have their strengths and weaknesses, Linux works perfectly well for a lot of use-cases, the graphics driver situation included.

As for Wayland not being network-transparent, the fact that it worked in X in the way it did was in fact a massive hack and a security hole and while sometimes convenient, I personally didn't need GUI over SSH almost ever, apart from playing around, so I'd take a proper security architecture, like Wayland has, over network transparency.

This is also not a feature supported by Windows/macOS, so not really a point against Linux in my book.

The early complaints, like screenshots etc. re Wayland were all resolved some time ago too.
I know nothing about io_uring but looking at the man page[1] of readv I see it returns number of bytes read. For me as a developer that's an unmistakable flag that partial reads is possible.

Was readv changed? The man page also states that partial reads is possible, but I guess that might have been added later?

If it always returned bytes read, it would hardly be the first case where the current behavior is mistaken for the specification. My fondest memory of that is all the OpenGL 1.x programs that broke when OpenGL 2.x was released.

This is an endlessly perplexing headline, as its core assertion, "C++ is faster and safer than Rust", is what the body of the article spends its whole time attempting to refute. A more accurate title for the content of this article would be "Debunking the myths that Rust is not safer or as fast as C++".
I used that approach for a reporting system and it worked pretty well. It was easy to hit the sheets api rate limit but it was just a matter of waiting a bit between requests.

My understanding is that overwhelming the health care system becomes easier the more spread the decease is. The real problem will be the lag in detecting the result of any public health measure with this virus. If only deaths can be measured the measurements will lag a few weeks potentially. With appropriate testing I guess the lag will still be a few days.

Now in the first wave you only had a few starting points as there were few sick people in few clusters. Today you have sick people all around the place. If the delay of measures are delayed in the second wave as much as in the first, the second wave will be much larger and it will be far less concentrated into clusters.

So this makes any policy change risky unless the measurement latency is very short. On top of this the impact of different policies is not known. So opening slowly makes it least somewhat scientific (understanding what works and what does not)

Of course the lockdown has a lot of negatives as well. I don't think many people dispute that. So it's a real a trade-off. But one that is very hard to get right because of all the unknowns, measurement latency (covid cases and side effects), and general emerging complexity of the problem.

On top of all this, this problem hits so many areas of public and private life. It's hard to nail down messaging to meet everybody.

So bottom line is it's hard to get right, therefore easy to criticize.
This article is a bit click-baity. It's more about busting myths by a particular C++ programmer against rust.

Anyway for a truth (well maybe it is a myth?) that we can't bust yet... Rust is simply not available on all platforms that C++ is. Two platforms that I think are missing:

* 16-bit MS-DOS

* 32-bit PowerPC (Linux)

Because a company’s stock price is in theory what the market expects is the sum of the total future discounted cash flows that unit of “equity” generates. [1]

This means that fundamentally, stocks are forward looking several decades and beyond. The economy right now might be bad but if the expectation is that there is a slow and long recovery lasting 2 years, if a company is expected to be operational, profitable and growing in year 3-year 10, those profits are built into the share price.
