Also it requires you to remember usernames or email addresses used at each website. For the last 8+ years I've been using unique usernames and emails at each website. I also have to deal with a number of systems that require me to change passwords every 3 months and I don't want to also be remembering dates.

I can't remember what the crisis was but it was after Ashley Madison and there had been a series of password databases put up on tor. And also there were some things about people getting harassed across platforms. It happened right before I moved to a new state and when I set up all my new utilities and banking and etc I used a password manager and created unique username flavors. Like fluidcruft253b for water and fluidcruftAdaG for gas and fluidcruft563d for banking etc.

What are some good resources for a quick intro to modern C++? I'm somewhat interested in Qt development and C++ seems inevitable in that environment.
I use katex on my pelican generated static site to do exactly this. Using this plugin [1], the latex is converted to MathML at compile time. Only thing that is loaded are the math fonts. There is no javascript involved.

Have a look at the floor for draughts. Our old methods of construction were pretty shocking. Look out for gaps underneath the skirting boards. Our walls are usually a double skin of brick and there will be air bricks to allow the gap between to dry out. Then you have floor/ceiling joists, probably with gaps around their ends. On the joists you will have floorboards, again with gaps between them. On the boards you will probably have some rubbish underlay and then carpet. Around the edges the walls will be finished with skirting boards. Over time the floors will sag.

You only report "one" hell of a draught coming from somewhere. There will be lots of draughts!
The only reliable number are deaths assuming people aren't hiding (or burning) the bodies. The number of tests are reliable among themselves, but we can't necessarily compare specificity and sensitivity of the tests against each other. Maybe those numbers are out there, but i haven't seen them.

The amount of infected is not and will not ever be known and it's a dark time for statistics when many are taking the non-randomly tested and dividing by fatalities and projecting deaths on large populations.

Exponential growth is how successful infections progress. There is nothing new to see here. This sort of aggressive strain was easily foreseeable years ago and we rely on strategic, planned measures to be executed by government.

Random, localized shutdowns only serve to exacerbate the unwarranted panic we are now seeing. The time to think was years in the coming, the actions now display an enormous failure in leadership.
The Reusability Fallacy
You wouldn't have to change them, but you'd have to remember the master password for the last "generations" to be able to access the older accounts.

Have you tested it out with the advanced summarizer?
Thank you very much for your encouragement. I will try to keep improving it.
I experimented with a similar idea, but with a solution that I think is simpler. My idea is called "Skipper": A dead-simple password keeper that is end-to-end encrypted, open-source, and free. A master password syncs your encrypted database store from any decentralized cloud hosting service. It's not fully featured yet, but others could add layers on top to add 2fa, proper federation/decentralization, etc.

The prototype works, but is super rough. https://github.com/syllable-hq/skipper

Well, that seems like a problem to me.
I would probably enjoy your republished site :)
>Basically, I added a concept of an `nonce` property, which is just a number that gets incremented every time a password for a service has to change.

So your solution to issues with stateless password managers is to... add state?
Great tool; watched videos with a couple pals who haven't been in the same room together for a decade!
As someone who was born and raised in America, the idea of a making a vaccine exclusive to the U.S. is morally repugnant, disgusting and outrageous. I hope that this doesn't come to be in this way. Any vaccine developed for COVID-19 should be free and shared with everyone regardless of income or geographical location. That is the only sane and compassionate thing to do. I hope more details emerge about this.
I would upvote this if I felt the source were reliable enough. Is Welt.de a well-regarded source?
I think that is much more a symptom of not having good core libraries built into the language in the first place. Programs written in modern C++ tend to make heavy use of the STL data structures. They aren't perfect, especially the maps, but they are solid and rarely a bottleneck. If you look at random numbers, time, the filesystem and even iostreams, there are plenty of rough edges to talk about it you want, but most people don't try to do their own thing in those areas because most programs don't need it at all.

People will fill in gaps, so it depends on what gaps are left and how big they are.

And how do you know this isn't government-made and a vaccine doesn't exist? Considering president Xi was at ground zero and then it's obvious he would catch the virus too. But he didn't, so maybe you and I do not have the full picture here?

Assumptions are the brother of all evil, just saying.. wait for confirmation before you start frothing at the lips

Speaking of the system, mainly the economic system, Jon Evans writes:

> We built it ourselves, after all; it was not handed down from Mount Sinai. Maybe we can fix it so that it encourages scientists and artists and engineers to start up truly new and better things, rather than more adtech and parasitical financial instruments.

We had a major push for technocratic post-capitalist reforms. It was called Communism. Then Communism failed in various disturbing ways worth remembering, and Capitalism had its revenge by destroy-ing communist ideology post-Soviet collapse, shifting the technocratic impetus from state engineered economies to a technocratic class to impose neoliberal "reforms" upon the working class, which is now coming apart.

Ignore what I said if you don't like my napkin history lesson, but the issue I want to point to is: how can we regain confidence in technocratic solutions when (a) Communist technocracies turned into nightmares, (b) we are in the middle of the decay of neoliberal technocracies, which include (c) an ever increasing skepticism of the only real vital technocracy left, the Internet.

Just when we need some scientific policy (particularly with climate change), the very idea of technocracy has fallen into the mud.

I don't think another Ted Talk is going to do it. The rot is deep.

Edited for grammar.
> and most definitely egrep and classic Thompson DFA construction and DFA->NFA conversion was definitely Unix folklore/taught in Uni

I think you mean "Thompson NFA construction" and "NFA->DFA."

Regardless though, this is not what the OP is pointing out. 'egrep' (or just GNU grep these days) is doing something more clever (emphasis mine):

> Al Aho expected his deterministic regular-expression recognizer would beat Ken's classic nondeterministic recognizer. Unfortunately, for single-shot use on complex regular expressions, Ken's could finish while egrep was still busy building a deterministic automaton. To finally gain the prize, Al sidestepped the curse of the automaton's exponentially big state table by inventing a way to build on the fly only the table entries that are actually visited during recognition.

Russ Cox talks about this a bit in part 3 of his articles on regex matching[1]. Its implementation in RE2 is here: https://github.com/google/re2/blob/master/re2/dfa.cc

Long term is what they're thinking of. Ie next winter and beyond.

And there are plenty of experts among the uk Gov't advisers too. "Pandemic" is #1 on the UK's list of national threats, and has been for ages. I'm certain this will have been modelled to death all that time.

Tbh, the "correct" advice depends mainly on your assumptions and priorities, not the mathematics.

I don't know who is handling this better, but Singapore also has people press on visibly filthy thumb scanners at immigration with no hand sanitiser to use afterwards (likewise other airports), bowls of candies for thousands of daily passengers to freely dip their sweaty hands into, and how do you rate this touchscreens in toilets, which seems like a terrible idea at any time.

Interesting idea, but that seems like overkill to me.

Like, yeah, if I was to sign up for Ashley Madison, it would be ideal for me to use an email that is not my known one. ;) But in most cases I don't think that's adding much extra security. If anything, you're more likely to lose access to a site by forgetting what your super secret email for it was than from someone hacking it.

This isn't to say that I'm totally against it. Part of me just feels like there's more that can go wrong doing it that way.
+1 for bitwarden, it's open-source (both client and server), and does the job well (only issue is the UI in the firefox extension can be a little frustrating).
Definitely. Noticing it's log scale (or anything non-linear) takes a trained eye.

I've worked with, presented, and consumed a lot of scientific data over my career and I still have a tendency to assume plots are linear no matter how many times I tell myself to always check scale first.
To me it's giving the right intuition and perspectives. I don't really care about the "raw" material/math, it comes only after good visualization based intuition.

In an ideal reactor, yes. In a real-world reactor the cooling is also essential because you built your reactor out of things with a melting point.
Social interaction in one's free time is a matter of preference - you can stay home alone, or ring up a friend and go for a coffee.

Aren’t we talking about where things were at in 2017 then?
The trouble is that these people need to compete against a subset of people who want power more than anything else.
These honest people decide it's not worth it, and get selected against and never make it to a position where they can affect change.

Alternatively, they do, and the process of getting there makes them less likely to do the things they wanted to do.

Any thoughts about the scheduling projects open sourced by staffjoy a few years ago, regarding the relevant schedule optimizers chosen? https://github.com/Staffjoy
uh... clojure is a lisp and supports full blown macros. Surem 95% of the time, Functions, plain data and a bit of polymorphism is all you need. those higher abstractions are for flattening the curve on making easy to use libraries. They are sharp tools. Go decides to hand you safety scissors, clojure gives you a high end razor sharp knife and expects you to be educated on its proper usage.
While there are less public broadcasts on shortwave then there once were, there is still plenty of utility stations, radio amateurs, and various other uses. By no means "bloody useless"
So what you've done there is a very common mistake. The US was not the only country built with this approach, it's just the only time it has worked (so far).

Plenty of countries especially in Latin America copied this choice and it didn't work for them. I think the evidence supports the conclusion that's because it's a bad choice.
In a sense, but not state that gets stored anywhere. The "state" that's being mentioned in this thread is referring to storing state in some kind of database. My idea was to not require storage of state outside of the human mind, and to make any state easily guessable(by the owner) through exhaustive search.

Even Lesspass uses an incremented number for that purpose, from what I can tell. So it adds state in the sense that you're talking about.
This reeks of the infamous dropbox comment on HN. Let alone the fact that the average user has no idea what SFTP is nor has any easy way to use it, even as a tech literate used who has no difficulty setting up the solution you describe, I would not switch from a more dedicated solution, because quite frankly it sucks. You have to manually sync, the sync cannot deal with two different systems adding different accounts, you now have two systems to deal with (sftp and keepass), and you're not significantly more secure. I would go back to reusing passwords before I adopted such a solution.

You can add Sweden to the western list, probably as an extreme case. Some regions are not even testing for the virus except in really ill people and healthcare workers. One region says it’s still testing but that it will no longer publish the numbers. We’re still a week or two behind Italy, but my feeling is it could get ugly...
Best Practices for Writing Clean Interfaces in Go
[T]here are many unknowns in how the SARS-CoV-2 virus interacts with the human immune system and how this might play into current scenarios. For example, we don’t yet know if this novel virus will induce long-term immunity in those affected as other related viruses do not.

That was really interesting to me. I didn't know infection with related viruses doesn't confer long-term immunity. Anybody know more precisely how closely related? All of Coronaviridae?
It isn't. It's the big brother of the tabloid 'Bild', from the same publisher, rephrasing typical right-wing populism and fear-mongering for readers who like to think they are intellectuals.
It's a lot of fun to play with. I used it at work to solve a partition assignment problem (you have data preintersected by property sets and a boolean query that constrains various properties, which set of preintersections are smallest for executing the query and cover all possible respondent documents?). Unfortunately it was not quite fast enough for our use case (runtimes of 50-100ms on harder queries) but it was fascinating to see provably optimal solutions to the problem.
It's the other way around.

You can't stop the spread to a complete halt, only slow it down.

If you want to stop the spread, you need to literally quarantine everyone for a months. Why? Because we don't really know yet how long some can infect people. The answer is probably "your mileage will vary" depending on how the disease evolves on an individual level. If you lift restrictions too soon, the few remaining infected will rekindle the epidemic among those who haven't had it yet.

> When it's over, the idea, as far as I've known, is that the risks are gone.

A highly contagious virus literally comes from Pandora's Box. Once out in the wild, it's extremely difficult to eradicate. We've only managed to willfully eradicate a handful of diseases thus far. Smallpox comes to mind. And that could only happen because of concerted vaccination program one the one hand, and the particular properties of the disease itself on the other hand.

Spanish flu disappeared after a year and an estimated 50 million dead - an optimistic estimate because no one really knows the true number. We don't really know why the flu disappeared. One theory simply holds that enough people had contracted the disease and had either survived or died by late 1918.

Without vaccination, social distancing and quarantining are the most viable strategies if we hope to slow down the spread in order to avoid the collapse of the healthcare system.

Why is that important? Because it's about avoiding as many deaths as we can while this runs it's course.

Every young-ish person who ends up in the ICU, is taking up a bed and resources of an older person or someone who suffers a precondition. Or even someone who got into an accident, had a stroke or a heart-attack.

It's your individual responsibility to avoid that you get infected, and equally important, that you don't pass it on to anyone else. Elderly and people your age alike.

As such, the entire strategy of achieving "herd immunity" is entirely backwards. Herd immunity will be achieved regardless how this plays out in the weeks and months to come. The real question is: At what price? And how many will we allow to die?

If the strategy is "let 'em have it", then the second order effect of that decision will be that many will die of causes that would have been treatable in other circumstances.
I think this story is blowing up due to the distinction between "exclusive supply of XXX million doses" and "exclusive IP rights".

The former is something I expect every government to be trying to do.

The latter, which seems to be the common interpretation of this story, is so unbelievable that I can't believe it. It doesn't even make sense, there's zero chance of such a business strategy even working. I doubt there is a single government on the planet that would enforce or respect a patent in this case if the price or supply of this vaccine is constrained in any way.
I’ve mostly heard the term ‘diorama’ in the context of museum exhibits. The diorama mode seems to have fallen out of favor, replaced by more interactive (and often digital) and interpretive installations.

Modelmaking as a hobby has been a somewhat popular at various times in the US, although much less in the past few decades. The high point, as with hobbies like photography, was probably 1970s-80s. But if you dig a bit, you’ll still find folks actively building model railroads, airplanes, cars & motorcycles, etc.
> These are simple tactics that every country should be utilizing.

Although simple, they have a large socio-economic impact.

There're many of us who are privileged enough to not work for a short period of time, but a large number of people can't afford that.

Is it worthwhile to shut-down schools before any reported cases? What if we encouraged those who are most vulnerable to quarantine themselves while the healthy population develops herd immunity?

I think the heavy-handed response is partially based on the notion that the virus can be contained. It cannot. It will continue to spread, if not in your own country it will in others around the globe. Viruses don't respect borders.

If we assume a that the spread cannot be stopped, then a better approach could be to maximize herd immunity while minimizing overall deaths and severe cases?
I reuse software every day when I use maven, pip, npm, etc.

2 cents:

I think the internet is the best way to distribute information, but for me one of the worst places to learn.

If the learning is solely done via the computer I will fail to even get near to completing the course (self-study, no pressure). But by using pens, paper, books etc, my ability gets to a normal level.

So, encourage them to behave close to the way they do in your classes.
