Bear market rallies are the absolute worst. They provide an outlet for pent-up demand and hope, while beating the tar out of shorts, who must close their positions by buying, driving prices unsustainably higher.

Rinse and repeat, all the way down the jagged slide of misery.

I must be missing something, because this Wikipedia chart shows that today's rally was the highest one-day percentage gain since 1929:

And that rally was 6x or so higher (258.47) than the eventual bottom (41.22)

Personally, though I agree the version number is going up too quickly, I appreciate that it at least aligns with their policy on breaking changes (which is to provide no hard guarantees on backwards compatibility).
I completely disagree. Can you give me an example? Perhaps you can change my mind.
Isn't this paper more about simulation techniques than about reality itself? It looks like time reversibiliy (sub-planck length or otherwise) should be studied in closed form or at least in non-lossy mathematical ways, not simulated with imprecise digital computers. Montecarlo simulation to calculate pi is just not a good way to know whether the digits of pi ever repeat or they don't.

If you want to play around with some of the improved code generation features of Clang/LLVM 10 for various architectures (MIPS, ARM, RISC-V, etc), but don't want to take the time to set up a full cross compilation environment, you could use the master branch tarballs[1] of Zig, which already are based on LLVM/Clang 10.

I just published a blog post[2] about this. You can use `zig cc` in the place of `clang`, and it'll unlock cross compilation.

Something to note is that depending on where you live, people can still go outside. They just need to stay away from people. If you live in a suburban or rural environment odds are there are at least walking paths nearby. Go on a walk, run, or bike ride. Nothing in those activities requires interacting with others as long as you keep a mind to keep your distance and they do wonders for keeping the cabin fever at bay.

Not meaning to rant, just something I wanted to get off my chest since people keep talking about being trapped indoors when practising social distancing (not quarantine. people under quarantine need to stay as isolated as possible).

I don't think the author misses that particular point. It's just that the author's goals are obviously different and way beyond just having documentation apparently. I mean, quote:

You should be able to hide all the definitions if you want or show only the definitions. You should be able to mark several code samples as doing the same thing in different languages. You should be able to generate the documentation with and without “TODO” sections, so you can share separate versions internally and externally

When I read that I was like 'wtf is this about'. For someone who barely has any documentation at all usually (me) this seems next level. But thinking of it this actually makes sense and I totally understand that if you're at the point where you want to apply those things you likely have a ton of ducumentation and perhaps don't need being pointed out that the main goal is writing it and you're most likely right in saying that markdwon is not the correct tool for that job.
That seems exceedingly reasonable. 4k when you need it, by a lower default.
If the number of significant digits required to maintain precision takes you past Planck length, you've reached an absolute physical limitation on your measurement ability.

If the process being measured is dependent on changes of sub-Planck length magnitude, you have an inherently chaotic system, and that makes it irreversible in practice.
It’s the usual “this is why we can’t have nice things”. Anything persistent will be turned into a tracking cookie. So eventually everything becomes ephemeral.

Does anyone know actual facts about testing in the US?

Yes, the CDC's tests were flawed, but ...

1) Other countries don't have a problem testing millions of people, so why doesn't the US use the same tests they do?

2) 3.5 weeks ago the Trump admin promised 1 million tests that week with many more to follow soon thereafter. After all this time they still haven't materialized, so what happened to the million tests?

3) Is there any reliable data on tests given by day, by city or state in the US today?

4) Is there some kind of struggle among different people or agencies in the US government, some wanting more testing and others trying to suppress testing?

I tried something similar to “spacer components” in a recent project. When I wrote them, I felt smug and clever: I had interpreted the suggestions in React about using components; I had separated my presentation concerns from content or functionality etc etc.

It turned out to be a mistake. It added a component (with JSX file, an index.js and a folder, and imports and uses in the consuming file. 10s of lines of code across multiple files and folders. After I had made it, I kept seeing the layout pattern it encoded in other parts of my app. I’d reuse the component, break it, refactor it to cover multiple uses, which sometime broke the original. I’d give up and make a new component that was slightly different. In the end I’d have several of these things, all with long names that were hard to interpret and harder to use.

And I was the only coder on that project. Imagine if you had several people doing this?

This kinda thing is the same as the problems people complain about when working with large CSS codebases.

Doing it in CSS is marginally easier, in my view. You probably have fewer files to maintain and fewer lines of code to work with.

Ultimately, I think the problem is in neither the CSS or JS. It’s that layout is really hard. It’s as subtle as language. We strive for regularity and consistency, but if we stick it it strictly, we hamper our ability to communicate.
I feel like an analogous discussion could be "please don't serialize your objects as JSON". But for all its warts and shortcomings there is a good reason JSON has become the format of choice in many domains. The same can be said of Markdown.
Microsoft CEO Bill Gates likely would have appeared as sociopathic as Amazon CEO Jeff Bezos, if not more so. The only question is what retired philanthropist Jeff Bezos would be like.
Agreed. Remember ancarda, it's always about the threat modeling. Every scenario has different business/user needs, and therefore, different tradeoffs that can/will be made. Sometimes, it does make sense to trade performance for security. (N.B. not always, or actually, probably not most of the time.)
The author claims in the notes that "The useful reals are similar, but not quite equivalent to other ideas in mathematics, such as [...] computable numbers."

Is that correct? What is the complement of the Computable Numbers in the Useful Reals? What is the complement of the Useful Reals in the Computable Numbers?

I've always thought of Computable Numbers as all numbers able to be represented by a finite string, ie: a computer program that would generate the number to any desired precision. How does that differ from the set of numbers with a finite symbolic representation?

Hmmmm... maybe by asking that question I've led myself to the answer. Chaitin's Constant has symbolic representations, one of which being the Wikipedia page that describes it: https://en.wikipedia.org/wiki/Chaitin%27s_constant. Does that mean it's included in the complement of the Computable Numbers in the Useful Reals? Are the Computable numbers a subset of the Useful Reals?

Google Open-Source's AutoML
now, I am an old fart. you shouldn't really listen to me, but here it goes: XML and xslt.

I have been using it with SSAX (XML and the scheme programming language, married in harmony) since 2005. It allows for structured documents that can be validated against a doctype in milliseconds and you can output whatever formats you wish.

I made a "documentation" doctype in 2005 and has used that to output documentation in whatever format I wanted (html, plain text, latex, markdown). Sure, it requires you to write XSLT or scheme using SSAX, but at least it will be your own fault whenever the tooling falls short.

my personal website is written XML, and generated server side using guile scheme and SSAX. I have been laughing quietly to myself every time people complain about the shortcomings of whatever markup their static site generator uses. Whenever I have had a need for something else, I can quickly edit my DTD in a backwards compatible way and add whatever sxslt transformations I need.

All that editing of HTML3.2 in notepad.exe made me immune to the ugliness of a light XML markup.
The CDC produced 160,000 tests that were defective. Meanwhile, the FDA did not allow anyone other than the CDC to test for coronavirus. That is the reason why the US was weeks behind on testing.

It’s larger than the rational numbers in the sense that it is a strict superset. Cardinality is what a lot of people reach for when they are talking about “larger” or “smaller”, but there are lots of other useful concepts which we can translate to “larger” and “smaller”.

So when someone says “larger” or “smaller”, your first step might be to try and translate that relationship into a more precise mathematical concept, like cardinality or measure.

Casual terminology also leads to weird discussions. Like when someone asks whether some function is “close” to another, and these functions are defined in terms of vector spaces. Unfortunately, “closeness” does not necessarily exist in a vector space. So the answer may be that the question does not make sense.

1) I don't need to 'defend' the system. Targetting works.

1b) "That's a garbage ecosystem and we would all be happier without them."

This is demonstrably false, unfortunately.

The ads power Facebook, Google, much of Entertainment. Almost everywhere you see an ad - that place would disappear without that ad.

So a 'future without ads' is essentially a future without any of those things - and you and anyone else can stop using those things right now, and thereby avoid both the ads and the service.

People chose the crappy ads, with the service, instead of the alternative: nothing.

Granted, there could be more paywalls, but there wouldn't be enough 'pay' to keep the services alive.

2) Yes, I'm 100% telling you that I don't believe your self-assessment of the kinds of ads you see overall. I think most people have no idea of the true inventory they are witnesses, rather, they remember only the tiny fragment that sticks out.

'Your evidence of sense' - is telling you that 'ads are a waste' when 'evidence of a $100B economy' and 'science' is definitely telling you that ads are effective. Even untargeted, or crudely targetted.

3) I don't think it's circular reasoning to point out that many ads are not targeted. You're missing the underlying point - that not all ads land on target, irrespective of how sophisticated the targetting in.

That inefficiency is accounted for in the system.

FYI - as part of 'item #2' not only are you going to be unaware of how many and which ads you saw, you're also going to be completely unaware of their effect on your behavior in most cases.

BMW has been advertising to you since the moment you could recognize their logo, a decade before you could even consider buying a car. That programming 'adds up' to something, no pun intended.

5) Your view of Facebook as a 'parasite' is your own, it's not objective - they have a Billion people who like using it just fine. You're also confusing the collapse of print and the complete commoditization of information, with ads.

I'm going to assume that you've never placed an ad of any kind, and have no exposure to the industry. I'd encourage trying it, even by spending $50 on FB or Google perhaps trying to garner interest in your favorite Open Source Project. You'll learn a lot in the process.

The irony of your ire ... is that better-targeted ads are generally better for everyone - both consumer and advertiser. They are the least annoying and most informative. Though we don't like the invasion of our privacy, the 'targetting' part is really good.

> Bill Gates says the US missed chance to avoid shutdown and should stay closed

The title doesn't match his quotes at all.

He's not ruling out stopping the shutdown.

He says it's to late if you want a containment strategy.

And politically people won't like a non shutdown plan.
Why do you think the glossary implies that? The glossary has "to copulate" plenty of places, so if the author thought cohabitation only meant copulation, they'd just put "to copulate" wouldn't they? It doesn't, it says the cohabitation ones mean cohabitation. So that's living together, not just having sex together.

Note that in certain religions, unmarried girls and guys aren't even allowed in a room alone with each other without a chaperone. Even today I hear lots of religious girls refuse to move in with someone until marriage. So living together even without any mention of sex is considered scandalous to certain people of certain times - thus requiring censoring in a 1919 treatise.

Heck, even in modern times, a block away from me, there's a mediation center where the guys and girls all have to sit on opposite sides of the building even though no one is having sex at a meditation center, and what the girls are allowed to wear is tightly restricted.

Thank you Andrew for all the work you've done on this! I'm very excited about being able to download zig and get the latest LLVM version AND be able to cross compile in a single go.

Yep Erlang is fairly procedural as a language in a sense. I don't think being functional was ever a priority, more like a side-effect. I don't know how mailboxes and message passing would really work in a purely functional language anyway, could be awkward to work with them. Particularly with a functional (ML or what have you) type system (how to type mailboxes?).

> it doesn't help with exploiting more cores.

Yeah you're right, I believe the aim is to get rid of those garbage collection pauses for better concurrency (not parallelism).

From what I understand, GHC can do pre-emptive or cooperative scheduling. Pre-emptive being better for concurrency, just like Erlang does it.

Darwin is open source. AMD Hackintosh users frequently compile custom Darwin kernels in order for macOS to run (although within the past year or so, this has fallen out of favor compared to binary patches).

Many kernel extensions are closed source, but that's not relevant here. What matters are Hackintosh kernel extensions like FakeSMC, which could absolutely be integrated into the kernel if necessary.

Edit: I just realized who I was talking too, you're more knowledgeable about iOS and macOS internals than I am! Are you referring to something different? I know absolutely that you can compile custom versions of Darwin, because as I mentioned it's done frequently for Hackintosh stuff.
