According to this US CDC site, 3M is the sole NIOSH manufacturer of N95 filters:

https://www.cdc.gov/niosh/npptl/topics/respirators/disp_part...

As an Earth scientist, I could imagine a mineral based replacement for the filtering part -- e.g. something like a zeolite -- but the lack of mechanical flexibility and the risk of silicosis are two serious problems with that right off the top of my head.

How about 3D printing of filters? Can N-95 -- 95% of particles greater than 0.3 microns -- be achieved?

Edited to add: It appears somebody is doing this for liquid filtration: https://liquico.com/products/

It sounds like a joke, I tried to reduce a technical manual but it didn't... well... I don't really know how to expect anything. This however: https://www.latimes.com/world-nation/story/2020-03-13/china-... worked really well.
For women: it may be worth your while checking out Project333. I have searched for a respective project for men, but haven't found something similar/worthy.

When I finished listening to the Minimalists podcast (first 120 episodes) for the second time I was already immersed in minimalism. I donated 90% of my clothes, I now have 5 t-shirts, 4 sweaters, 2 jeans, 10 pairs of socks, 2 pairs of shoes, and some snow/skiing related accessories (hoods, etc.)

I also have "office clothes" which I don't count as clothes, I treat them as a uniform, when not in the office, they don't exist for me (and Coronavirus-->remote working was a great 'gift' for me on this area)(I hope the deaths stop and we continue the WFH).

I see fashion as a "subscription" scheme. You spend £€¥$, you get clothes and after X seasons you need to spend another load of £€¥$ to renew your "trendy-ness".

I can never forget that in the term "fashion VICTIM" the word that sticks with YOU is the word "victim".
> I wonder if the delay in implementation has anything to do with the abundance of use of MathJax, making working on it low-priority.

I've thought the exact same thing before.

In the future I'm planning some articles with math on my personal website, and my current intention is to only use MathML without any JS renderer. I use Firefox so this isn't a problem for me. This would make the page a fair bit lighter, rendering time faster, and maybe make web developers using Chrome think twice about ensuring compatibility as too many websites are Chrome-only these days. ;-) [1]

Seems that there is some progress in getting MathML in Chrome so possibly by the time these articles go online, there won't be an issue.

[1] One major example I noticed in the past few days is that https://wiki.c2.com/ no longer seems to work in Firefox at all. I just get an error saying "Trouble Encountered". Works fine in Chromium.

In my experience middle level managers are the gate keepers to work from home. Developers are willing to work from home, while managers especially people managers are afraid their work might be perceived by the company as unnecessary. If WFH has to become norm then company should assure managers their job security.
I think most dairy cows are Holstein-Friesian, so black and white (with some regressive red and white, although Guernsey are also usually red and white). Brown dairy cows (Swiss, Jersey) are the minority of the milking population.

(Not promoting/affiliated to eBay)
When I made the decision to buy second hand clothes, I only though of eBay (have been buying stuff since 2001(?). I always seem to find a nice sweater etc, I don't mind if the size is a bit off, I can always resell. I would love it if anyone can suggest any other online stores that sell 2nd hand clothes at the volume/options that eBay (it's sellers) can provide.
I don't believe that's "the only time people get upset". Even if no one ever quits, this has got to be causing lots of drama. In most places I've worked, managers did management and hourly workers did not. When you want to abuse an hourly worker like this, you have to move them to a salary. Traditionally that salary would be a bump up from their 40-hour wage.
Scientific advice shouldn't be ambiguous.

Germany doesn't test well at all.
My wife's school in Berlin has been closed since Thursday because of a positive parent who partied in a club the same night as over 16 now infected persons.

Teachers are still waiting for test results and are supposed yo come back to work on Monday.

I can't really explain why there are so few casualties yet in Germany, but I think it's because many young and healthy people got infected (that's the case in Berlin, for instance), so hospitals aren't yet saturated.

I hope it stays that way, but I think we can expect much more deaths in the next days.
That's some good underwear :D

I buy new clothes only when my old ones are visibly faded or start getting ripped (or when I spill something that can't be washed). May be the influence of video games, but I've got standard outfits for different situations and travel distance, so I buy 2-3 of the same clothes (wear one set - wash the others). I see other people try to wear something different/new every other day...

> P-Orridge’s genius didn’t lie in her artistic skills, but rather in her ability to manipulate others

It's true. His now her talent in any musical configuration was always adding a non-musical element. I would liken him now her to a hype man, like Flava Flav, but one that has traveled through and beyond a permanently state of drug induced psychosis to land on some distant shore, mysterious, disturbing, pointless, raw, Dionysian in the Paglian sense (not necessarily in the sense of N).

I love GP because sheitwhat proves that the absolutely psychologically depraved can find a place in this world, can be of value, too. It's an important and reassuring lesson.
Statsepidemiolog Anders Tegnell säger att resonemanget om flockimmunitet ”delvis” stämmer, men att det inte är myndighetens strategi. – Vårt huvudsyfte nu är att få smittspridningen att gå så långsamt som möjligt.

...which translates to...

State epidemiologist Anders Tegnell says the reasoning around herd immunity is partly correct but that it is not the organisation's strategy - our main goal now is to get the infection to spread as slow as possible

...but the Swedish government is not actually doing much to limit the spread of the disease other than telling people who show symptoms to stay at home. By now it has mostly been proven that infected people spread the infection for a few days before they show symptoms and the fact that children can be and often seem to be asymptomatic carriers the spread will be rapid and result in a large number of people in need of medical care. The Swedish health care system was already overloaded before the pandemic so it will not be able to handle a large number of patients in need of critical care. The same scenario is now playing out in Italy so this should not come as a surprise.
Why not follow Singapore and have both? Any greenery you cut down to build something must be replaced, and in Singapore that happens to be replaced by becoming part of the building itself.

I'm not an expert, and I'm sure it's more complex than this in practice, but if each infected individual transmits the infection to n others, and you assume that a fraction f of the population are immune, you want

(1-f)*n < 1

to avoid exponential growth, so

f = 1 - 1/n

Your examples cover a range of 1.7 to 3.3 as estimates for n, which is roughly aligned with what I've heard reported.

I have found that my shirts were getting holes in the armpits area, and I discovered that the drying rack is causing this. Since then I use 2-3 racks/'lanes' per item, so the weight of a wet garment is spread out and also helps the garment dry faster since air can circulate. I also make sure the armpit regions of the t-shirts aren't right on the wire but a bit lower.
> Instead of cutting down trees and putting up buildings, how about cutting down buildings and putting up trees?

Yes, please. Living in NYC I have seen so many trees disappear. Every single remodel or development cuts down every green thing and paves over anything which can spawn life. It makes the neighborhood look bare revealing all the dirt and grime.

With KaTeX's 'output' option (https://katex.org/docs/next/options.html) you can have both. For providing accessibility for screen readers, TeX formula copying etc. you have to choose one of the MathML options of course. For pure rendering, the html is good enough (even with Chrome).

But the point is to prevent the health service from getting overrun. By the time it is, it's too late because you'll already have an order of magnitude more people who are infected but not yet showing symptoms.
My aunt and uncle's house has 1642 written on it, which was when it was last rebuilt from scratch. For the last few hundred years or so it has been simply patched with more mud, straw and horse piss. It too has no foundations to speak of unless you count the rather hard earth on which it stands. I tried smacking it with a lump hammer and once I'd stopped vibrating, I could not see a dent in it. One day I'll get a decent sized masonry bit out and see just how hard it really is but I suspect it is harder or at least tougher than the modern concrete base in my 1920s job.

Back on topic, we have a 50' walnut tree in our garden that we tend to. It gets a feed every other year. Next door is a 100+ acre park, mostly woodland: oak, ash, beech, horse chestnut etc. It is really starting to look lovely after a 10 year plan to get rid of the laurels, which were planted about 150 odd years back but have turned out to be invasive, poisonous and left unchecked nearly took over completely.

> why is so much harder for C++ than for the JavaScript folks?

There are C++ package managers that exist and work - they tend to be your OS' package manager, because of the problems they will have to work around.

Because C++ has a lot more flexibility in core components than JavaScript does, which aren't easy to resolve at the package manager level.

Things projects may _require_ to build correctly:

* Multiple compilers that don't always have compatible extensions that sometimes share the same flags, and can falsely report to be each other when queried.

* Multiple simultaneous differing versions of clib to link against. They may requiring differing specific versions of specific implementations.

* Specific kernel libraries to link against. You can't easily build and link against a specific OS kernel in isolation.

* Projects may expect specific paths, and ignore or break attempts to change these. Not being able to compile a project that has a history of twenty years isn't an option.

* Arbitrary execution with intentional side-effects. It's bad, but there is a very long history of projects that you're dealing with here.

* CPATH and CXXPATH are globals. Relative path linking is possible, but difficult and a pile of hacks. You can force a node_modules style to exist, and some projects do, but most are a mix of relative and global, and the global can override your local and break things.
Rust code just builds. a typical library will pull in hundreds of dependencies... and they will all just build (eventually). There are downsides to the approach but they are papercuts. Did I mention that Rust code builds? As in, you tell cargo to build something... And then it builds it? Type cargo build and enjoy the blinkenlights.

Not "almost nothing to do" - putting programs into a readable normal form seems the natural evolution of these tools.

When I started programming in the 90s, "spaces-and-braces" checking - as you say, nitpicking - was basically all we had, along with limited automatic tools to fix them (all more or less as good as `M-x indent-region`). If you were lucky and in a widely-used language you could cobble together compiler warnings, lint, and a few other tools to also get warnings about legacy interfaces (gets), dangerous practices (ignoring error codes), and unusual structure (shadowed variables, loop conditions that seemed impossible). Today we finally have considerably better tools that don't just check if you match a style guide but do a full reformat (not nitpicking, but doing it for you) and linters that can enforce 'deeper' structural demands, sometimes with automatic fixes.

But 40 years ago we had tools to completely restructure programs to a normalized form, and the practical experience to know programmers found this form preferable! And like so many things in our field, 10-20 years later we had to rediscover it, painfully, all over again. Probably because today's programmers think source-to-source Fortran/Ratfor translation has "almost nothing to do" with the challenges facing them today.

I don't understand this. In what case would there ever be "past" account passwords that I would have to change?
This seems like an overblown concern. How often are aluminum frames actually failing? How many miles and how many years do you have to put on one before it fails? And how do these figures contrast with steel? And don't forget that steel is more susceptible to rust than aluminum is, so depending on climate and salting conditions the steel might fail first.

My aluminum road bike cost me $600 new and I have four years of daily commuting on it so far. It's still in good condition and I expect to get many more years of riding out of it. At this rate I'm gonna have it for longer than the average car ownership period in the US (which is about 7 years).

The fears are being blown out of proportion.

This isn't pushing development, this sounds like jumping in near the end of development and waving a chequebook to obtain the vaccine for sole use.

Interesting perspective, thanks for sharing your experience! That doesn't sound too much worse than working with modern CMake build systems, but it also doesn't sound mucn better.

>People put meaningless, nonsensical junk in their CMake files and expect it to output something that builds. Doesn't matter that the build script or the IDE are fundamentally broken, people just want the output so they can get back to their work.

When you put it that way, maybe that's my real pet peeve with CMake in big projects :)

Couple this with ast and source similarity search (how this is enabled is tbd) would allow one to not only suggest how to complete the program via the compiler's analysis, but then also find code that was similar to your program across all source say in crates.io or on github.

Great learning tool, but also the ability to copy-pasta from terabytes of code ... (scurries off to do some analysis).
