> ...the masks don't work rhetoric is political maneuvering born from the fact that governments had little to no reserves of them and that health professionals desperately need them.

Lying to people erodes trust. When leaders then order subsequent weeks-months of lockdown, people don't trust them, ignore their orders, and protest.

It's not just the masks, though. Leaders failed to lay out plans and exit criteria fast enough, weren't fast enough to address arbitrariness in their orders, and have downplayed knock-on effects.
Interview with “Impala Beats” Female Producer/Beatmaker “Julia Tarasova”
Well, in enterprise Saas usually the pricing is not shown on the website without contacting a sales rep, so it usually eliminates companies which don't have a lot of money.

But even if a small company is reaching to you, as a salesperson, this is your job to qualify the lead, and to not loose your time on a lead that has low chance of signing
"Cows make milk. They milk themselves.
Other cows check the milk (for free).
Cows - get this - PAY THE FARMER to take the milk away.
Then the farmer (you won't believe this, honestly) sells the milk back to the cows.
Sometimes the farmer lets the cow drink a tiny bit of its own milk.
The farmer calls it 'longstanding commitment to Open Access'."

I have a rough upper bound on the costs of collecting, hosting, distributing, archiving, and indexing academic papers across the world: arXiv.

The publishers provide no real value to the publishing process except their prestigious conference and/or journal names and the conference events themselves. The latter should be decoupled from the publishing process (and they charge through the nose for conference attendance, anyway).
Companies that cut half of the pay are unlikely to offer corporate housing or free food.

Even remote interns need to live somewhere and rent isn't cheap. On the other hand, interns might be ok with sharing a 2bd apt with 3 roommates and paying only 600 for rent and bills. That would leave them almost 2000 a month. Not bad for a 20 yo seeking independence, but humiliating for a 25 yo and a complete failure for a 30 yo.

If Lyft is open to hiring interns from abroad (unlikely) and pay them the same 4800 (very unlikely), then just 500 would get them a very decent 2bd apt. In countries like India, they would be borderline rich with this kind of money.
The title is inaccurate, they acknowledge on the first paragraph that it captures large droplets. that's reason enough to wear the mask

Yes, that's basically correct, but think less econ and more accounting.

Keep in mind:

1) That the $20/bbl cost is likely with capex amortized on the assumption that the well isn't shut-in. You'd either have to add a one-time write-off for the capex balance (if you can afford to), or at least re-amortize. Either way, looking at the existing/assumed $/bbl cost vs market price isn't correct for most decision making purposes.

2) The act of shutting-in (and re-starting production) have direct costs to be accounted for. It's not as simple as pushing a button that activates a remote controlled valve. There's (almost) always physical work to be done, plus compliance / permitting work associated with any changes. More-so for restarts, if you assume the shut-in will be temporary, and want to account for that cost in decision making.

3) opex costs are largely still discrete to some extent (ie, not literally a cost in $/bbl, except pipeline transport and royalties), and can still be sunk costs.

Shutting-in wells doesn't necessarily reduce opex to $0, whether immediately or longer term.

Yearly maintenance might have been done last week. Tanker service already contracted for the year, or a direct pipeline already built. Lease and permit fees paid for the next X years. The lease might be contracted at some fixed cost plus royalties, for 10+ years, with the fixed cost guaranteed.

New for 2020: If the company took a PPP loan (or otherwise is trying to avoid layoffs) they have to keep surplus personnel, which then becomes a sunk cost.

Now if you look at exploration instead of production, it's much more likely to be a textbook case of if (cost > price), then (stop work immediately).
This mask discussion makes me think like I am taking crazy pills. Can someone explain to me how placing a barrier in front of your mouth and nose can possibly be a BAD idea when the purpose is to reduce the entry of particles into the system? Why do we need studies to prove this? If you are inhaling it is likely to stop some particles from getting in. If you are exhaling it is likely to stop some particles from getting out. Sure, particles might still get in or out but HOW CAN IT BE WORSE THAN LITERALLY BEING EXPOSED ALL THE TIME?

This feels like the parachute example to me that was posted here a few days ago. You don't need to do a study to prove that a man hitting the ground at 10km/h would be more likely to survive than one hitting at 150km/h. Sure, parachutes can fail, but how can they be worse off than NOT wearing a parachute?

It almost feels like the health agencies were caught with their pants down telling absolute lies about masks for over a month and are now scrambling to salvage some dignity from the affair by throwing studies at us. Just imagine how much we could have reduced transmission if Americans had started wearing masks in late February or at least early March.

This lie has literally cost the world billions of dollars, not to mention thousands of lives.
Having one foot in Japanese culture and the other in American, I think there's a lot of saving face in Japan too (as with Asian and Western cultures in general), just it doesn't take the form of cover-ups in the business world as much.

It's not foreign in American culture, either. My understanding is in the us Navy for junior officers and enlisteds anyways covering up is the worst thing you can do; you can cause catastrophic accidents that if they don't kill anyone will result in no punishment besides a "what did we learn here?" lecture.

Not as true in the upper, more political ranks so I understand.
There are some subtle ones. It depends on what you need. :)

Assuming you trust the WSJ to have conducted the survey in an honest and non-leading manner, but I thought we weren't supposed to be trusting "biased media." The article starts off by portraying net neutrality as "pro-regulation" - I'd imagine a good number of people who are pro-net-neutrality would not have answered yes to, say, "Did you send a letter to the FCC favoring additional regulation on the internet?" despite having done so. We'd need to see exactly what the survey said and how they worded it.

They also haven't given you enough information to know the size of the pro-NN batch they investigated, so we still don't know that it's "massive."
A good few years ago now, I was working with an illustrator/artist developing a few websites for bands like Cuff The Duke, PS I Love You, and Bahamas.

Nothing was shared between sites, lots of cutting up pngs for link headers, cryptic navigation, all that stuff I have to avoid doing now.

It was probably the most fun I had working with a designer.
I see you get my point. This site was better when there was no (visible) moderation beyond upvotes, downvotes, and flags from users.
There is almost no one that is worth tens of thousands per hour. Most "big companies" overpay for people with fancy titles that produce a lot of noise but not a lot of output. Small companies have no choice but to be highly efficient and that's why they have lower levels of pay inequality.

Chances are that 95% of people is what is bringing in 95% of the value of your company.
I suggest clicking through to the NAP paper, which unlike this reporting fluff/hype piece, is very reasonable.

This is part of the standard academic fake science pipeline. The researchers did reasonable work (best summary: "We don't know how well they work"). The university PR departments turned that into hyped-up nonsense to gain publicity and brand recognition. Next step will be science reporting, which will exaggerate the press release, and finally, popular news, which will use this to bash random policy decisions.

Direct link to the original paper:

https://www.nap.edu/read/25776/chapter/1

In general, NAP pieces tend to be well-researched and well-written summaries of what's known. This one is no exception.
It's your machine, but you are talking about software you don't control. This would imply that the software won't always follow your rules.
It's such a shame that COVID-19 has become so politicized, it's hard to even find scientific sources that are being wholeheartedly honest. Here's a few statements that are blatantly misleading:

> Around 1 in 20 people infected with COVID-19 need to go to an ICU (Intensive Care Unit).

That statistic is contingent on infection rates. No one has these due to lack of testing. Therefore, the statistic is misleading at best, and wrong at worst.

> However, pandemics are like poker. Make bets only when you're 95% sure, and you'll lose everything at stake.

This is highly alarmist. Pandemics aren't like poker because you're not going "all-in" on a 95% bet. Awful analogy, and just bad rhetoric.

> (Rant about the confusion about pre-symptomatic vs "true" asymptomatic. "True" asymptomatics are rare.)

Let's be real. In the study cited, N was like 900 (with asymptomatics = 4; 1.9%). We have no idea how "rare" asymptomatics are, and citing this study is just bad science. I don't understand why not just be honest.
If you're running Ubuntu's server, odds are that you're SSH-ing into the box instead of running graphical interface. Unless you specifically install snaps, I don't see how this would affect you.
It's not legal. You seem so sure of yourself.
This title seems misleading to me.

The title implies that we have data showing cloth masks don’t work, but what the article actually says is just that we don’t have data.
You may not mean it this way, but the your post makes it sound like complexity is created out of whole cloth (so to speak) by adding (in your scenario) searchable old emails.

And true to the article, that is only half of the equation. Complexity is not created as much as it is moved around. By adding code that makes old emails searchable instead of simply archiving them moves the business complexity of customers with this specific edge case to your code base.

It is then a business decision. And I agree with you that it is often not worth it, but the art of business is in understanding when taking on the added complexity is worth it to differentiate your product over your competitors. Or stated another way, strategically deciding to reduce the complexity of your customer's business and increasing the complexity of your own.

This is not always an obvious decision, hence why the developer rank and file often look at it from one side only, and the product manager's/sales staff often look at it from their side.

It takes a strong leader who understands both sides to make the right strategic decision. When this decision is not made thoughtfully you end up with an overburden of complexity for a subset of customers that don't really move the needle on your business.
That would be very new. Maybe for research positions (postdoc). But for internships minimal wage does not apply.
It's hard to get science on any of this. Things like "how long does SARS-CoV2 live on x are cute," but in vitro data doesn't equate to the real risk--it's more like a worst-case bound. If you're playing with latex spheres, it might as well be a guess.
Yeah, I remember this... fontconfig can be kind of a bear. Once you find a configuration that works for you, save your fonts.conf somewhere so you don't have to do it again.

The Debian wiki page on fonts is helpful. The Arch wiki page is better, and most of it still applies:

Ubuntu is doing more harm than good to desktop linux at this point in time.

Continuing to push Xorg over Wayland.
Removing support for flatpak (cross-distro way of using sandboxed apps)
Horrible PPA system that works much worse in practice than the AUR or other ports systems.
No daemonless docker (podman)

Lots of people try Ubuntu since it is the "most popular" version of Linux, realize it isn't great and think desktop Linux is in bad shape. The reality is Canonical doesn't seem to have good ideas and refuses to incorporate the good ideas from other distros.
Jay, I just wanted to say thanks to all the groundbreaking work you’ve done in the jailbreaking scene. Ages ago I had an iPad Touch and I had so much fun jailbreaking it and playing around with Cydia tweaks.
Yes so regardless of what language or where the language runs, we give you a container, inside that container we drop in a server that's responsible for most of the functionality including editing, collaboration, hosting, etc. A little about that here: https://blog.repl.it/collab

The IDE is built on top of a window-tiling manager abstraction we built in React.js: https://blog.repl.it/ide

Now, as for languages, most of them do run inside the container, which is built from our base image polygott (https://github.com/replit/polygott). However, a select-few are better suited to run on the client. We have a client-side jail called: replbox (https://github.com/replit/replbox). Basic, for example, runs on replbox because I wanted to graphics to be instant. For something like PyGame or LOVE frameworks we had to go with VNC streaming but that's not ideal for obvious network reasons.

There is a lot more to it -- it sometimes feels like building an entire city -- and you can find some more posts on our blog: https://blog.repl.it/ (which incidentally is hosted on Repl.it).
No one honest can, because masks do help. What's not clear is how much they help. They'd have a huge effect on large droplets, but potentially a very small effect on bioaerosols. Until we know more about how COVID19 typically spreads, we don't know how important they are.

In contrast to the intentionally dishonest UMN fluff PR piece, that's what the NAP paper it claims to summarize says.

The one really big effect not talked about is that it also means I can't unconsciously touch my mouth or nose. Remember the "don't touch your face" campaign?

> the exhaust velocity of the main engines of the Space Shuttle, 4.4 km/s. It's not clear why this is considered to be groundbreaking.

And ion thrusters have an exhaust velocity in the 20-50 km/s range. Things can be groundbreaking for different reasons.

But in the case of this article, I dont think the velocity mentioned is the exhaust velocity. It says the "rotating detonations are continuous, Mach 5 explosions". This is likely the flame front speed inside the combustion chamber (a traditional rocket engine has subsonic flame front, ie conflagration not detonation). The exhaust velocity is a different measurement, after the nozzle/bell (converts thermal to kinetic energy). Here [1] for more details.

I'm interested to hear more about the possibilities this combustion chamber design brings up.

Not arguing for/against masks, merely pointing out the analogy. For your parachute analogy. Imagine that its given the parachute will have very large holes (similar to the droplets being very very small). Its useless having a parchute in that case.
I'd argue that almost 100% of users, myself included, can't really make this analysis for any given update. Usually you can't anticipate what will brake, that's what makes upgrades scary.

What everybody does however is to use past experiences to evaluate the risks. Who hasn't had a system upgrade break something that took a while to fix? In these conditions, who wants their system to auto-update if the system is critical and it could happen at the worst possible moment?

As I said I try to keep my system up to date, but if I know that I have an important deadline in the near future I'm likely to postpone updates to avoid shooting myself in the foot.
I too have had those roles, starting my career as an IC, then a middle Manager, then a consultant, then a CEO/founder, and now a CTO. What I’ve focused on is how to help my teams and then my company operate as efficiently as possible while spending our resources where it benefits our customers the most.

Some examples of decisions I’ve made:

- IT/engineers won’t spend time building and maintaining email servers, we’ll spend $5/month/employee on G Suite and use their time on things that make our products more valuable

- We won’t outsource support even though that would dollar for dollar be more efficient, because understanding and building empathy for the customer is more important

- no we won’t spend money on email lists, but yes we will spend money on tools that allows our outbound sales team to more quickly determine prospects that fit our ideal customer profile

- bringing finance in-house much sooner than other people recommended because being more efficient at Accounts Receivable, Renewals, and thus cash flow allowed us to grow faster than we otherwise would have

- paying for a third party SSO solution for our products and instead using engineering time to build first class integrations between our products and complementary products, because having an artisanal SSO System doesn’t benefit our customers
I want to implement a toy programming language, but I have questions regarding the following in that article:

> Context free grammars. What this really means is the code should be parseable without having to look things up in a symbol table. C++ is famously not a context free grammar. A context free grammar, besides making things a lot simpler, means that IDEs can do syntax highlighting without integrating in most of a compiler front end, i.e. third party tools become much more likely to exist.

Many complex languages, like c++, rust are not context free. We therefore need semantic analysis.

What programming language features will be compromised if I stick to context free?

Will the end result be as expressive as c++/rust?

Any programming language that is massively adopted is context free?

BTW, the toy language I want to build will be something similar to javascript.
A highly relevant thing for your search is something known as the Jamstack [1].

People typically use "Static Site Generators" to create blogs which relies more on content than on fancy login flows or database connection flows. Those flows are still possible but Jamstack allows for a low bar high ceiling scenario when you are starting to build your own blog.

To compare the endless list of static site generators, what they are and how you write posts, go to StaticGen [2]. My recommendation:
- Pick "Hugo" for a great out-of-the-box experience with fair flexibility.
- Pick "Gatsby" for virtually unlimited flexibility with React-based generator.

Imagine that having the mask encourages you to go out and be around people.

If you would otherwise self-isolate if you didn't have a mask, the mask has increased your chances of getting yourself and others sick.
Have a look at static site generators. I‘ve used both Hugo and Nextjs and can recommend them.

Also there is nothing wrong with just editing html directly. It is a very good starting point for many projects like personal sites and other small projects.
"As a freelance AI engineer, you are expected to, for example, start with a client, familiarize yourself with the product and the codebase, submit the first PR within a couple of days"

Although I have my doubts maybe this is true specifically for AI area. In general contracting, getting familiar with the large project and "submitting the first PR within a couple of days" is a wet dream. I will exclude cases when one is hired to find and fix bug in some simple, short piece of code.
Agreed. I use Hubspot as a model - stellar inbound strategy, but still has a very strong outbound strategy too.

And tbh, the majority of sales I've ever made were from outbound. Usually very targeted outbound where I had the prospect more/less pre-qualified (after talking to lots of prospects you develop an instinct)

Any citations to your claim that most people care 'a ton'? I think most people would prefer simpler stuff over the flash if they could see the benefits but i have no proof, so i won't claim it's a fact.

The reader mode note was simply to say I prefer the text only style.

The second paragraph is there because this article is talking about a simple web page, and I'm complaining that more sites don't do simple styles.

that's not what happened. if you click the link you included, your "self-respect?" comment isn't on that thread at all. because it was a reply to my comment. you're intentionally misrepresenting what happened.

let me point out how you "slipped" and took a "rude swipe" - you don't play by your own rules.

i made a post, you replied to me just saying "self-respect?" implying that i had none.

how can you just drop insulting comments like that on people who are just participating in conversation? two words, no explanation, just plain rude.

Isn't your "self-respect?" comment in bad-faith, given your own rules?

"Please don't post shallow dismissals, especially of other people's work. A good critical comment teaches us something."

"Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith."

"Be kind. Don't be snarky. Have curious conversation; don't cross-examine. Comments should get more thoughtful and substantive, not less, as a topic gets more divisive."

From the New Yorker profile of you:

"They treat their community like an encounter group or Esalen workshop; often, they correspond with individual Hacker News readers over e-mail, coaching and encouraging them in long, heartfelt exchanges."

Is that just BS? What was encouraging or heartfelt about your response to me?
