I appreciate this answer, it sounded facile at first, but hints at a significant ambiguity when calling something 'my' problem. You are absolutely correct that my daughter's problems are my problems, but their motivation and the manner in which they must be dealt with are fundamentally different from the rumination that causes [me?] ennui.

Taking a fundamentally trite example: my daughter wants a pencil so that she might draw. Fundamentally, she's not concerned about me solving the 'pencil problem' utterly, for all time, but rather wants one 'now'; that is, ideally within ~30s but definitely within ~5 minutes. There is no time to dwell on the merits of STAEDTLER vs Caran d'Ache, or whether I should be provisioning a set focused on soft or hard lead, or a lifetime supply of Ticonderogas. Instead, you find the first one that you already have around that has a reasonable chance of keeping its lead intact long enough to allow her to finish her doodle and move on to the next thing.

So yes, I agree with your premise, but I also argue that the problems you inherit by proxy are materially different from the ones I [at least] find cause ennui.
Similar to the train being stopped by a toilet flush, in the 90's, I worked with devices based on Microsoft's Pocket PC OS. These were equipped with wireless radios. The transmission of a packet caused some interference that the device interpreted as a click on the screen. The cursor was over the [X] to close the application window, so the application would just quit, looking like it crashed.
I don't think it necessarily has to be true. I also built a profitable system and wrote about it, but I didn't share all the details. Not even close. There are just too many small details that must be "just right" that they would fill a whole book. It's kind of like building an operating system from scratch. It's not something you can put into a single post or paper. There isn't one "trick" that suddenly makes it all profitable - it's a combination of so many small details.

Then there is the cultural aspect. People who are working in trading are just not used to sharing openly. They don't write online, or anywhere. They are not even allowed to write due to their employers. And people who work in academia are naturally not working on "production" systems - their only job is to write, not to build. So you almost never see people in the intersection of: writes-online & understands-trading & is-not-in-academia

In my experience, this isn't true. When revising, most of my time is spent considering what changes I can make and not putting them into practice. If the bottleneck is thinking, raising your typing speed will provide marginal gains at best.
Coronavirus can cause blood clots and may lead to strokes
It's a weird subject for academic study in the first place. Trying do do trading strategies that beat the market is one of the few things that really is a zero-sum game. In the absence of independent scientific interest to optimizing these strategies, what's the point? You might as well study how to optimize strategies for ultimate frisbee or something.
Hmm takes about 5 minutes of googling to find annualised GDP per-capita growth rates for countries.

Using the 1990-2015 period (because the numbers are directly available on wikipedia: https://en.wikipedia.org/wiki/List_of_countries_by_GDP_growt...).

The following countries all grew by MORE than Germany: Poland (8.5%), Romania (6.9%), Lithuania (6.9%), Slovakia (6.7%), Czech Republic (6.6%), Estonia (6.4%), Ireland (6.2%), Latvia (5.8%), Hungary (5.5%), Malta (5.1%), Bulgaria (4.7%), Luxembourg (4.6%), Norway (3.9%), Portugal (3.6%), Slovenia (3.3%), Croatia (3.1%), United Kingdom (3.1%) and the Netherlands (3.0%).

Germany's rate for the same period was 2.9%.

So you're theory that Germany has benefited the most from the EU - at least for this period - is clearly false.

It is a zero sum game. Nobody is producing anything, therefore for one to win another must lose.

Surely the right response to that isn't to always be more worked up.
You're being willfully obtuse here. No one in the US would call their 401k a pension.
I was impressed to read that the IPFS public network scaled 30X in 2019. It sounds like they have gotten over a big hump for usability and utility.
I do have a very small pension benefit. They eliminated the pension for new employees in 2013, and the existing pensions were frozen sometime around 2016 or 2017.
While people did worry about the space taken up by the bounds checking information, systems 10 years older than the PDP-11 had enough hardware resources to support high level systems programming languages with bounds checking data structures, let alone the beefy PDP-11 (by comparison with those older models).

Thanks for the feedback! Building the landing page was really one of the trickiest parts for me.

I understand their desire to use a library, but there's a faster and safer way to do this that's more C-like if you have access to the compiler:

Just locate anything declared as an array in a particular linker section so the pointer manipulation can be done with two (or one if it's at the top of memory) comparison, possibly even to a constant.

If you do this you can even forbid pointer arithmetic except in actual []-declared memory, and can do transparent bounds checking (&array-1 can hold the array length or, possibly faster, the address of the location after the end of the array).

An advantage of this over the library route is you can prevent pointer/array punning but otherwise allow any C program to work fine. And apart from a few corner cases (there are legit non-array uses of pointer arithmetic, though very few) and noncompliant program can be changed to use [] and still work perfectly fine without this option being used.
> I would prefer that states have more power and we further decentralize authority away from the federal government.

No EPA. No DOE. No equality under the law. No EOC. No NLRB. No Amtrak. No federal enforcement of consent decrees. No voting right act. No gay marriage, etc?

Edit: Thanks for downvotes. Every single one of these is enforced by federal and not state courts. It is federal court that gave us Roe v. Wade, for example. It is a federal court that prevents Alabama from running its own little fiefdom. It is a federal courts that gave us Brown v. Board of Education.

0.999...=1 is true in the mathematical sense, period.

However as a representation of physical world, there is a caveat. What we understand is physical world appears and behaves discretely, because at planck scale (approx. 10^-35) the distances seem to behave discretely.

Although common people don't know/ understand planck scale, they do grasp this concept intuitively. What they are really saying is that in physical world there's some small interval (more precisely, about[1 - 10^-35, 1]) which can't be subdivided further, based on our current knowledge.

Same thing applies to planck time (approx. 5 * 10^-43) too.

So people are arguing two different things - the pure maths concept, or the real world interpretation.

I understand, HTML is a document but it has this disadvantages and IMO if we want to use HTML everywhere we need some default Widgets for List and Table, don't change anything about current HTML but similar on how we have a Video or Canvas element we might want something for this uses cases and not force each developer re-invent the wheel. If is not built=int he browser I would like some sane JS implementation (framework independent and without any dependencies on 100 left-pads),

This thing where each developer re=invents same thing over and over and each implementation is broken in some way it bothers me, like the search input in Youtube has a dropdown with some suggestion, that dropdown popup can get stuck open until you reload the page, so even Google engineers are not capable of implementing a 100% working simple Widget.
"Sharing databases across services (micro or not) is generally a pretty bad idea"

I don't think such a blanket statement is justified. There are plenty of situations where it may make sense to pull out some functionality into its own service--so it can be written in a different language, scaled independently, isolated from failures, or whatever--but where giving that service its own separate database would be serious overkill, complicating ops and introducing potential data integrity issues for no real benefit.

"If your deployment relies on synchronized service deployments you really dont have independent services at all."

So what? That's really the point: blindly following the Microservices (TM) doctrine is often a mistake. It's better to just solve whatever problem you're facing in the simplest possible way. While that may mean by-the-book microservices with independent databases, in many cases something in between is a better choice.

How the pandemic made this virologist an unlikely cult figure
You didn't really answer the question about the value of the compression. There are 2 options:

1- If people are using their own E2E encryption below your tunnel, then your compression provides essentially zero value, since properly encrypted traffic should not have repeating patterns to compress.

2- If you are telling people to not use their own E2E encryption, and instead rely on the Lynk tunnel's E2E encryption (with Lynk applying compression before encryption) then people are exposing their raw traffic to you, a seemingly random person on the internet.
The thing is, right now there seems to be a disturbing pattern of the world falling apart at the end of every GOP administration. This is problematic, because we still need the GOP so that we can vote out democrats when they mismanage the nation's affairs. We can't have one party, that's not safe for us as the citizenry for obvious reasons.

At the same time, we can't have this, "the world ends", at the end of every GOP administration either. So we really do need to fix this.

The alternative is we get some different parties, and I've seen little to no indication of that happening. The other parties have neither shown an ability to evoke a response large enough to get elected. Nor have they shown an ability to govern even in the extremely unlikely event that they were elected.

For the foreseeable future, we are stuck with the dem-rep dichotomy. Which can work. We just need for the reps to stop running the nation into the ground when it's their turn. Other nations have shown us that reasonable and effective responses to the pandemic were possible. Why are we here? What is the set of missteps or issues that got us here? We have to identify those issues, and fix them.
Agree, except for that last part.

At this stage OP won't know which backend language/tech will be best suited to whichever idea ends up taking off.

So, best to just use whichever is most popular (and with the best trajectory) since popularity leads to other advantages. Choosing rails now, for example, would not make sense.

> In cats, for example, infection with feline enteric coronavirus may last for months or longer. When this happens, the virus mutates so much that its very nature seems to change. What starts out as a relatively mild gastrointestinal infection eventually causes serious peritonitis (inflammation of the membrane lining the abdominal wall) in some animals. Examining the virus at this point in the infection, researchers found that the mutations had resulted in the emergence of a related virus, feline infectious peritonitis virus — and this one has a higher fatality rate.

Can someone explain this to me, are they saying that the virus mutated into another virus? What conditions would it need to be a new virus rather than a variation of the original one?

Bit of advice: If you don't know something, remain silent or say you don't know or ask a question. Don't confidently assert something you just made up.
The virus inflames the blood vessels, which makes diffusion of gases between the lungs and the bloodstream more difficult. This leads to hypoxia. The hypoxic cascade it causes leads to hemes detaching, becoming free hemes, which has to bind to nitric oxide. As time goes on, nitric oxide gets depleted, and you end up with pulmonary embolism or clotting, which is a natural consequence of low NO. If people went to the hospital at the first sign of stroke, and received NO treatment, this would be avoidable. The young people who died in NYC ignored stroke symptoms for a day or more on average, so while education is important, it is treatable if caught.

Microsoft Beats Earnings; Revenue up 15%
Note the "-ish". I know that they aren't actually new, and that many "new paradigms" are actually rebranded old stuff (I have been writing software since the early 1980s, and have seen these waves sweeping through the industry; often, with some amusement).

What does happen, though, is that a canon develops, based on these technologies, and [actual] new techniques get created, based on them.

Some of these are nightmares, and need to be strangled before they can crawl off the slab, but sometimes, a gem comes up.

I write about some of my experiences around that here: https://littlegreenviper.com/miscellany/concrete-galoshes/#e...

I remember writing "object-oriented" software for classic C, in the late 1980s. I called it the "faux object" pattern, and was based in state being kept in a structure that was passed around functions. I refined and formalized the idea when I encountered Apple's QuickDraw GX in the early '90s (I suspect that may be the only good thing that I ever got from that sad debacle).

I used the faux object pattern in an SDK I designed in 1994, and it's still being used to this day. Back then, you couldn't pass OOP across module connections, so we had to figure out a way to do it with C.

Nowadays, I can easily pass Swift extensions and virtual implementations across SDKs; no sweat. It's cool.

I like the post but it does somewhat miss the point of these comments when they’re made. It’s not usually someone saying they could rebuild the whole site / product / company in a weekend but rather challenging the value that everything beyond MVP is adding and all the staff that go into supporting everything beyond MVP.

Companies tend to vastly over-complicate things and to support that end up having ever growing teams to support the ever growing over-complexity and feature bloat.

I can’t tell you the number of times a team has said it takes so long to deliver something with 3x the number of engineers because they need more testing, backend and such but meanwhile the core product features that customers care about are delayed and not materializing. It’s not that these other things don’t matter but all the “other stuff” shouldn’t take priority over having a lean and mean product that works and people use.

Thus it’s less “why does this company have 100 engineers” and more “why does this company not just exist as a far simpler and leaner product?”
Not sure. The good thing about rails vs flight is that you can swap out the energy source. As your energy production gets greener your entire travel gets greener. With airlines, it is not even a remote possibility to change from kerosine based engines to electric or other green alternatives, Europe is very small and relatively dense. It would be a great way of commuting.

An additional problem with this is that they use A3C here for trading. A3C is known to not be suitable for adversarial environments (e.g. board games, like Chess).

I wrote a paper that demonstrated that A3C is as exploitable as a uniform random strategy in board games (specifically, some poker variants): https://arxiv.org/abs/2004.09677

(Exploitable is a technical term that is defined in the paper; basically, it's "how much can someone who knows everything about your strategy beat you by?")

So I would be very surprised if this survives contact with other traders.
