Filtering face-piece respirator having a face seal comprising a water-vapor-breathable layer Patent Assignee 3M INNOVATIVE PROPERTIES COMPANY (St. Paul, MN, US)

http://www.freepatentsonline.com/9408424.html

In discussing a way to take water vapour from exhaled breath away from the filter surface. If this is the case while the polyurethane is the primary material the pulp fibre is applied to it as a layer which may not appear in a spec sheet.

"In some embodiments, a face seal may consist only of a water-vapor-breathable layer and a wicking layer (that is located on the rearward side of at least a portion of the water-vapor-breathable layer), with no other layers being present. In other embodiments, other layers may be present in the face seal.

There are several general approaches to providing such a wicking layer, which approaches will be described herein in a non-limiting manner. In one approach, a fibrous wicking layer (e.g., a non-woven web, a woven or knitted fabric, and so on) can be comprised (e.g., generally, substantially, or completely) of fibers with “moderate” hydrophilicity. Materials that might be suitable for such fibers include e.g. certain nylons, polyesters, cellulose acetates, and so on. In another approach, a fibrous wicking layer can be comprised of relatively hydrophobic fibers (e.g., polyethylene, polypropylene, natural rubber, and so on), but with the web incorporating some portion of relatively hydrophilic fibers (e.g., cellulosic fibers, acrylic fibers comprising a significant amount of hydrophilic co-monomer, and so on). That is, any suitable blend of hydrophobic fibers and hydrophilic fibers can be used to arrive at the optimum balance of properties. In a variation of such approaches, a fibrous wicking layer can be comprised of relatively hydrophobic fibers but may further comprise hydrophilic particles of any suitable composition (e.g. hydrocolloids, WOOD PULP, starch particles, and so on). Conversely, a fibrous wicking layer can be comprised of relatively hydrophilic fibers but may further comprise hydrophobic particles of any suitable composition."
> If somebody hands over an application to me where configs have unit tests, this means to me that the application can fail catastrophically under certain (unwanted) configurations

This would be a sign of a program that allowed input (configuration, in this case) that was unsafe. That is completely a different matter to whether a programing language is suitable for defining configuration. I suspect that many an application has been written that assumes that because it's consuming "static" configuration that is a simple text file, or a structured data file, that the input is completely safe. (SQL injection can come from any direction.)
As another HN member mentioned, this is a pretty awful article.
What is the alleged conflict supposed to be?

It's my understanding that quantum mechanics necessarily describes systems in a single inertial reference frame, so for that system, time is absolute w.r.t to both general relativity and QM.
I don't hate you I pity you. Applied for Big N jobs last year, had to study leetcode for 1 month and I hated my life. I was legit depressed. I was already so busy at work and coming home to do leetcode just killed all motivation and happiness in my life. Did well enough to get to on site interviews but didn't get a full time offer from any of them. Such is life :(
Why do I get the feeling that when they do finally figure out what time is it's somehow going to be related to imaginary numbers:

I believe it looks like this: https://en.wikipedia.org/wiki/Speed_of_light

That physical limitation on how fast a mass can move is what keeps causality in check and things like the grandfather paradox from being possible.

>For example, it does not have words for numbers

It has two official number systems (described in the official Toki Pona book - https://tokipona.org ). They're not practical for big numbers, and they are a bit cumbersome, but they're there.

>left and right.
I've never had it be necessary to use these words. Often "on my/your side" if I'm walking with someone, or "beside/towards X" if there's a feature there.

(it has deficiencies, and can be cumbersome, but these aren't them)

>Does anyone knows of some kind of slightly extended version of Toki Pona?

certain people add/coin words to do certain things, and some people use obsolete/archaic ones, but nothing's caught on generally. More generally think there's a world of minlangs (minimalistic languages), but I don't know much about it, alas.
It's quite niche, but I've been really enjoying Pico8 [0], a 'fantasy console' retro game creation system. It's got quite a few limitations, but I've found it quite fun to explore game dev concepts without being tempted by perfection.

It's got simplified editors for tiles, sprites, maps, music, sound and code, runs on desktops + raspberry pis, and can export to web. The code you write is lua, with builtins for all the editable resources, and paves over most, if not all, the technical rabbit holes you can get yourself into with game development.

While naming the different derivation rules can be useful for guiding readers the names are not formally necessary.

The rules

A B
-----
C

and

A B
----- (→c)
C

are logically equivalent, the latter just gives you a name to refer to the rule by.

Additionally, I would be careful about correcting others that something is "technically" called something else as programming language researchers often use many names for the same concept.

Fun fact:

Array(1, 2, 3)
someList(0)
array(0) = 23.42
map("name") = "Joe"

All of this is valid MUMPS syntax and does what you'd think.

I'd loooove to hear the author's thoughts on the above then extending weird parentheses syntax crap to function calls, MUMPS style too:

USER>s foo(1) = "hi,there"
USER>s $p(foo(1), ",", 2) = "you"
USER>w foo(1)
hi,you
USER>

Maybe I'm warning of a slippery slope here, but this is a direction that I'm not sure you'll want to go down.

Also a fun fact, MUMPS has very dynamic typing and thus very much no type annotations.
Yeah. I had originally mocked up a command-prompt, scripting language etc., but in the end I realised the only thing I actually wanted to do with it was write, so I focussed on that as my goal :)

I'm not sure I agree.

While technically bronchitis could be any inflammation of the brochial tubes, a diagnosis of bronchitis usually means that that it's the patient's major problem. It'd be odd to describe a cancer as "bronchitis" even if it involved brochi. So you do learn something, in a Griceian sense, from the relatively uninformative diagnosis. There's also the implication that there are some tools for managing it, the doctor's seen it before, etc all of which are reassuring.

Pretty common when new managers "get an idea."

A new manager at Google wanted to shift Adsense (I believe) to Oracle Enterprise from MySQL. Some favorable MySQL benchmarks stopped that.

Responsys was all-Windows for quite a while. They eventually migrated their server farm to Linux. Almost certainly a combination of performance and an internal license audit (using Microsoft server products to scale a SaaS is brutally expensive.)

EDIT: I might have misunderstood the context of some of my parent comments, I do not believe that progressive tax brackets should be increase the tax rate on the entire income, just of the income over a certain limit.

> They are anti-consumer in the sense that they raise prices without offering more or better goods in return.

There is also to say that economy of scale is real, so (within bounds, I wouldn't meddle in guessing numbers) it is reasonable to ask the company making 10 billion per year to be more efficient per-dollar than a 2-persons shop.

Regarding the EU I believe you are missing the point. Farming in the EU (outside of the Netherlands apparently) is almost by definition going to be a terrible business profit wise in an unregulated market; too little to automate too high cost of living for workers.

The regulations in place exist because of an explicit consideration that keeping those industries alive (especially regional traditional products) is something with a value in and of itself.

For sure many regulations have serious issues and some of them are plainly wrong, but arguing for anarcho-capitalism to me sound as reasonable as arguing for communism.
Learning the bond market, figuring out the different characteristics of all the different types of bonds, what the risks are, what the potential for gain is.

I trade options on equities regularly and recently a friend has been looking for help on figuring out how to handle a large amount of money they came into, so I figured brushing up on bond investing would be helpful since their risk tolerance is substantially lower than mine.
Don't get me wrong, I love IBM POWER and am currently contributing to the LibreSOC/LibreGPU

Who are POWER9 server customers for example? Seems a bit more expensive than competing Xeon.
I believe digital tools are scoped like analog ones are - they are appropriate for certain types of projects.

In the same way it would be extremely hard to do say, a convincing rendition of the waldstein sonata on say, a drum kit, the digital tools are great if you want to do what they're designed to do.

This is why some people love one piece of software and hate another in some apparently random distribution, music is a huge tent and these people likely have dramatically different goals. It's like a kosher, a vegan, and a keto arguing over the best restaurant...

The problem is trying to figure out whether it's the wrong tool or whether you just haven't spent enough time learning how to use it.
I honestly think it has everything to do with having started it in the early 90s and just keeping his customers happy for 30ish years. He has several big local commercial clients from his early years that still use him because they know he or one of his staff will always show up.

Also I think the bigger players in the space, ABM-types, aren’t interested in commercial space smaller than XX,000 sqft where my dad has been able to fit in nicely.

Reinforced concrete is used mostly in Spain, where I live. Then walls are either traditional bricks, or some plasterboards stuffed with insulation, or an outer layer of thin bricks, insulation, and an inner layer of plaster.

I think we're moving away from bricks because everybody has A/C now. But houses are still "solid", with a concrete skeleton and walls that you can't "punch through", at least the outer walls.
If the mass of employers has more money to spend, they automatically create more jobs because they spend it. This is a no-brainer. They are the relevant part of every country out there and the whole system. This is why companies like Walmart are so huge. Many people spending small amounts of money generating huge revenue.

Your rich investor who gains a little bit more due to tax evasion of the company they invested in gives you nothing most of the time because they just reinvest it elsewhere and even if he buys one more yacht with it, they are so few, that their impact on the job market is negligible.

Now the fact that the company which does not pay the taxes for the infrastructure they freely use to generate their revenue can go to a politician and tell him: "give me taxpayer money/let me pay less tax or I go to the county next door" does not have anything to do with employment. It's a hole in national law. If there would be no politician who's allowed to throw money at those already wealthy companies, they would have null leverage, the subsidies would go to those who really need it, the companies would have to pay their taxes (you can't outsource everything) and the mass of citizens would profit from more money in their pocket, a properly maintained infrastructure and money the state has in emergencies like we're witnessing today.

Your "single dimension" view on the situation is the old prayer those who steal taxpayer money/not pay for what they use have told us for years. It's a ridiculously shitty story nobody buys, so please get a dimension.
Unless we're talking about some specific cases of dependency injection, adding logic to your configurations sounds like a living hell. Can you imagine the exponential explosion of complexity that you'd have to deal with? How do you even _test_ something like this?

If you program requires configurations so dynamic that it needs to be its own program, there's something very smelly about your architecture. Next thing we'll need is a config config to config your config, etc. Infinite regression into a very stupid place.

I had a similar thought process not long ago. I found this post from a 2 years ago: https://news.ycombinator.com/item?id=18757972

That's an entire book that is merely a guide on which other books to read and what to focus on in one's journey of formal logic.

I have started with the most intro book it recommends "How to Prove It : A Structured Approach by Daniel J. Velleman". It seems to be quite similar to whatever text book I used in the class that focused on logic in college. I intend to skip around a bit though as my real goal here is to be able to understand all of this advanced type theory that I keep seeing in the FP/Haskell/Idris world.
I'm very much a software person, so I decided to learn more about hardware and the design of circuits. Pretty cool stuff.
Seems it was also discussed earlier on HackerNews about how POWER9 isn't unreasonably expensive - but couldn't seem to glean who are the real server customers.

I think Warren Buffet said "only when the tide goes out do you discover who has been swimming naked". What I can't get over is that we just found out basically everyone is swimming naked.

Businesses lose cash flow for one month and they can't pay workers. Workers miss one paycheck and they can't make rent. Landlords miss one rent payment and can't pay their mortgage. Banks start seeing mortgage defaults and immediately need a bailout. Everyone's broke! It's broke all the way down. If any one of those in that chain kept a little emergency fund, we wouldn't be in this situation. How did we all manage to build an economy such that we're all paying each other just-in-time to avoid catastrophe?
Yeah, but the landlords will increase their rents to account for the risk that you will stop bailing them out.

Landlords already take risk that you stink as a renter. What's new is that everyone stinks simultaneously for the first time in many decades.

Firefox had been a bad browser for years, the only people I ever meet who use it heavily are tech enthusiasts and privacy activists. If nobody is choosing your browser for practical reasons then you've failed to make a useful browser but pointing this out only ever results in jeering and being told some token line like "Compromise means the erosion of privacy!". This is what that philosophy gets you and down the line I expect the real situation will be Firefox in 4th since Brave has been gaining momentum too.
Thia isn't specific to news. It's everything in the marketplace. Anything for sale is optimized for short term profit -- lowest cost of production, highest impulse purchase pressure -- junk food, fake healthy food, furniture made of shoddy materials, shiny appliances that will break, etc.
Ah, maybe I wasn't clear enough there -- the validator/analyser is supposed to run by both parties, the party who writes config, and the party who loads it as well. So you can reject a malicious config before trying to execute it.

I mostly have a non-malicious user in mind though (i.e. end-user software, where the software and the config have same permissions)

If you do have such security concerns, you probably need a sandbox at some point. E.g. big source of my frustration are CI pipelines -- they run isolated anyway and execute arbitrary code. Having a YAML there does nothing for the security.

There is nothing sophistic about this argument. It's pretty obvious.

This is why some people argue that we might be living in a simulation. Because we don't have direct (not mediated by our senses) access to the underlying reality.
