Pros: all true

Cons: Every single one of these is false, especially the face touching part.

Folks, this is what I'm talking about so let's do this by the numbers.

>You need to touch your face more often which increases the risk

You touch your face less (read: zero) when in environments in which you're wearing the mask. And if you're wearing it in public places that's enormously important, since that is where you will get the virus.

>Mask becomes humid after a while which is great eniviroment for the virus.

The micro-environment of "your mouth and nose" is not going to breed any more virus than the environment around you that wants to inject the virus into your mouth and nose.

>False sense of security - people engaging in risky behavoiur

[citation needed]

>Not enough masks for hospitals

And if we'd stopped lying about masks being effective back in early February perhaps we'd have enough of them by now. So let's stop lying about it now to make sure we have enough by May.
>so any contamination their masks "stopped" is just waiting for the next use to infect the wearer

It's true the virus may linger and infect later, but it might also be destroyed in the meantime. The odds depend on various factors, such as exposure to sunlight, antiviral chemicals, or high temperatures.

I have said this before but the way Slack is used today is most of the time a net negative of the modern workplace.

And I will agree that it's mainly because people use it badly but Slack encourages to use it as a dopamine fix contributing to an ever lower attention span in the workspace.

An IM tool is needed in the modern workspace but it should be seen as the last resort. A synchronous answer should not be expected. Instead, Slack has been pushed as the replacement of email and is being used as the single place where all the discussions are going on in real-time, making it extremely difficult to work on a complex task without taking the risk of missing an important decision/discussion.

I find it amazing that this tool is used unquestionably by every small/medium company without ever wondering if it really provides a productivity benefit.
This all seems a bit mad. As if the prospect of writing some code before the test is so horrifying that it requires this much explaining away.

I love Python as a "hack it into a Frankenstein monster for fun" language because of how much power you have to get under the hood. For that reason I love articles like this.

But I'm not sure you'd ever want to implement overloading for practical uses. Just utilize optional arguments and some branching logic within the function. But even then, rethink how much you're trying to pack into a function.

I don't know how good professional tracking is, but I can tell you that I definitely get useful information from my Oura ring that has lead to an improvement in my sleep. Many small things, but the obvious one is how much even a drink or two of alcohol is affecting sleep for half the night.

Obviously won't help with tracking leg movements, though. Just for a quick confirmation I'd recommend a web camera, but there won't be statistics from it.
It's not just about people with symptoms to get tested. It's about people who are known to have had contact with infected to get tested. Also importantly you want to regularly (at least once a week) test health workers and others who are in contact with vulnerable people. And finally, by doing lots of so called sentinel tests (random testing around the country) you can get a much better picture of how the virus spreads.

In short it is not about your interest if you get tested it is about societies interest.

Before I went to university to read physics, I devoured their (and others) popular science books, and had a pretty good understanding of the majority of the material on my degree course before I started it - the degree filled in the blanks, annealed the maths in my mind - but there’s little as good as a book written by an expert on a topic to imbue knowledge.

> K8S doesn't eliminate the workflow for "deployments, upgrades, monitoring, etc.." it just black boxes them.

Kubernetes does not black box anything. At most it abstracts the computer cluster comprised of heterogeneous COTS computers, as well as the heterogeneous networks they communicate over and the OS they run on.

I'm starting to believe that the bulk of the criticism directed at Kubernetes is made up by arrogant developers who look at a sysadmin job, fail to undertand or value it, and proceed to try to pin the blame on a tool just because their ubriss doesn't allow them to acknowledge they are not competent in a different domain. After all, if they are unable to get containerized applications to deploy, configure, and run on a cluster of COTS hardware communicating over a software-defined network abstracting both intra and internet then of course the tool is the problem.

I’ve been seeing a lot of social media posts from friends and family who are wearing masks incorrectly or making their own masks. That might not be a huge problem on its own, but it seems to give them an excuse to risk compensate. And that’s a huge problem.

If you plop on an N95 mask, it’s not going to work as intended. Sure, it might block some stuff and discourage you from touching your face, but it’s certainly not going to make you invincible. Even when fitted correctly, it’s still letting stuff through. If you have to choose between staying home vs. gathering in a group while wearing a mask, one is obviously lower risk than the other.

N95 masks are uncomfortable. When used correctly, you feel like you’re breathing hot, humid air that you just exhaled. They clamp down pretty tightly on your nose.

People don’t like this, so they adjust the mask until it’s comfortable (or just don’t fit it in the first place)—and in this case, comfort = leak. Or they get a mask with an exhaust vent—which might protect the wearer reasonably well, but now everything they exhale exits the mask unfiltered. Or—and this is my favorite one—they put the mask on over sunglasses to keep it from sitting on the bridge of their nose, then wonder why their glasses fog up.

Or perhaps they have facial hair that they don’t want to shave. For the seal to work, the part making contact with your face needs to be clean-shaven.

And you can’t make your own N95 mask from scratch. They’re not simple cloth; that’s why they’re expensive and hard to produce.

Again, none of this would be terrible if people didn’t risk compensate. Wearing any mask—even incorrectly—is probably better than no mask, as long as you didn’t cut up a fiberglass HEPA filter in the process. Wearing a mask to get some groceries or pick up a prescription? Great! At the very least, it’ll keep you from touching your face. But wearing a mask so you can throw a party is a terrible idea.

I’m mostly targeting N95 masks here since they’re not as easy to use as surgical masks, but the same general rule applies to everything: masks are an extra tool in your arsenal; another layer of protection. They don’t make you invincible.
Or hey, let's try this radical idea to just have protected sex unless we have both been tested.
it's a natural reaction to having a thing down your throat. i woke up in the ICU once with a tube in. my wrists were bound down so I wouldn't pull it out (which i would have, in my newly awakened stupor). once awake and lucid i was fine to have hands freed.
I have to say, it’s sad to me that your lesson to your past self was to act in a more ruthless and uncaring manner.

> Sell more.

This is so obvious, that is easy to miss.

To share my story (which contains a lot of luck, so, or rather good "timing"). I started my small logistics / supply chain start-up last October, theplan was to have first, meaningful discussions about prices and contracts in June / July and have first revenue in August / September.

Pretty privileged to be ablt to afford almost a year without revenue, right? My targeted market was solar modules from China / Asia to Europe and eCommerce fulfillment logistics.

Now, with logistics in place (software not so much), covering th whole chain from China to consumers in Europe I am talking to organisations in germany to help them et supplies from Asia to hospitals and so on. I am basically selling three months earlier than planned. And i realized that my enxiety about reaching out to customers and try selling my services is all but gone after a couple of days.

So: Sell more. Get revenue.

And don't be greedy. The whole idea of getting into medical supplies (I am not going to charge more than my own minimum salary and actual costs) comes from an inquery to run logistics for a business importing hand sanitzer to be sold through Ebay and Amazon. Show some business ethics. Nobody expects companies to turn into charities, but at the very least don't charge more for customers during crisis because of the crisis than you would have otherwise. Should be great for a long-term relationship.
I’ve never thought of Slack as a tool primarily for remote work. I suspect the vast majority of their customers are non-remote companies.
You have to distinguish between viruses in abstract and a concrete disease. Many viral diseases we are fighting with are human only. So if we erradicate it in humanity, it is gone. This is how smallpox went away. We vaccinated enough people to make it go away once and for ever. Measels have no animal host either, as far as I am aware, so we could have a good chance to erradicate it too.

The corona virus sars-cov-2, as well as the first sars virus jumped from animals to humans. There are several animal species which carry variations of the sars virus, but fortunately, they don't make the transition to humans regularly. If we managed to prevent further transmissions of sars-cov-2 between people, there is a good chance, this virus could go away entirely, unless it manages to jump to some common animal.
I think it’s called Slack.

If your client/prospect asks you to lower your rate, have a conversation with them on why they request that. Do they need N% cost saving? Perhaps you can you work N% less than. Or negotiate longer contracts (or longer notice periods to stop the project) in return.

It could be that more professionals in your market (either freelance or employees) are becoming available, changing the demand-supply, which would normally lower the rater. Part of your rate is likely based on the scarcity of your craft. If that changes, don't be too proud to change your rate. But also don't just accept a lower rate without questions.
> The only people who are arguing "more research is needed" are social science professors and their PhD candidates.

Social scientists generally don't do these kinds of studies. A more typical research question might be something like "what forms of volunteering do italian grandpas take part in, and what are the perceived benefits do these efforts for themselves and the communities they serve?" This would be addressed through open-ended semi-structured interviews through various sampling methods, but probably a snowball sampling strategy. The research goes in the directions that the subjects lead it in, with effort being made to tie up loose ends as part of a theory-building process. Basically a structured and evidence-based attempt to come up with a coherent explanation.

Well, it would have been helpful to provide a simple example of a working pwa.

The example at

https://codelabs.developers.google.com/codelabs/your-first-p...

was way too complicated as a first example, if all I wanted to know was how to make my app installable and is also broken as it uses some outdated tools. (don't remember the details)

Also, it could have been mentioned somewhere, that when you serve from localhost, you do not need SSL to install it. Knowing that, would have saved me the trouble of messing with apaches config and certificates.

So that was very frustrating as a start.

Much more helpful was a very simple hello world pwa which was barely installable. But it worked. And from there it was easy.

If the users aren't paying enough, they still fail. If they don't have a positive cash flow, they still fail.

Which reminds me of an interview with a German logistics start-up recently. They are funded by 100 million €, a lot of cash for what is basically a simple forwarder. When the co-founder said, that they don't see any risk for them, because their run-way is somewhere between 12 and 18 months I was shocked They have customers, they charge a margin for every transport. Yet they seem not to be cash positive. And their burn rate is at the very least somewhere around 2 million per months.

Coming from that industry, I have no idea how that is even remotely possible. If the crisis would have hit 6 months later, their situation would have been a lot different. And that during a period where everyone is scrambling to keep transportation and logistics running.
Only feedback I have is that SEO probably doesn't belong as a fundamental given it's not relevant when you're using web tech to build non-public web applications and sites.
I’m purely guessing, but maybe the traffic deaths have decreased linearly with traffic, and violent crime in some porportion to gathering size.

That is to say, that it’s due to less activity and not a changed mindset.
I agree.

I've said before on this site, obscurity is a totally valid tactic to impose additional costs on attackers. It's best to think of it more as a preemptive strike than a defensive layer. Thinking of it as a defensive layer can lead to complacency, but thinking of it as an opening gambit is totally fine.

One shouldn't be obsequious to heuristics like "never use security through obscurity," one should understand the systems they're building and make considered choices.

Additionally, preventing people from dumping your firmware is usually not about security as much as it is preventing some fly-by-night company from reversing your product & selling it as their own. Why engineer a product when you can steal someone else's IP?
I can assure you with 100 percent certainty that Rentech et al will relatively thrive with the trading tax.

This tax will reduce liquidity perhaps, make the market pricing inefficient (larger spread). This will hurt mutual funds the most by increasing their baseline costs. Which in turn will hurt pension funds, endowments, etc.

RenTech and others will thrive in the midst of those inefficiencies.
In theory yes, but in practical terms probably not, as it is unlikely that we get the whole humanity in a lockdown and of course there are still human-human contacts. This is the reason, it is unlikely that we get rid of sars-cov-2 entirely once the global spread was beyond a certain threashold.
But in practical terms one could espect a lot of infectious diseases to be drastically reduced in case numbers.
Are they intubating COVID-19 patients without general anesthesia? I've been in the hospital a month due to pneumonia and have been intubated 3 times. The second and third times they did intubation and extubation all under general.

The first time they put some kind of special tube in under general. When I came to 3 days later there was no ventilator, and the end of the tube was in my throat. It felt like a rectangular block. They extubated me while I was awake and immediately put me on high flow oxygen. They would've intubated me on the spot if I couldn't breathe. Never felt a gagging sensation in this instance.

You can implement end-to-end encrypted applications e.g. with the subtle crypto API, though there’s always a debate of whether this really provides good privacy as the website owner or an adversary who can inject code can still change the JS and steal the data. Personally I think it’s still much better as the data at rest is encrypted and only the user can decrypt it. Now the problem is of course that if the user forgets his/her password the data is gone. To alleviate that you can again think up some schemes like encrypting the encryption key with an asymmetric scheme where the private key is kept secure by the website owner, but that then requires a process for securely using this key... So it’s possible but not trivial I would say!

This is something our education system does a poor job at.

My observation from watching a 3.5-year-old all the time is that bootstrapping most skills (e.g. riding a 2-wheeled scooter, solving simple logic puzzles, drawing, cutting with scissors, building structures out of construction toys) does not require frequent or extensive practice per se, but only practice spaced out in time, combined with a positive emotional outlook. The student can try something with limited success for a little while (maybe 15–30 minutes), go away for a few weeks, come try again and fail again, go away for another few weeks, etc., and after a few months there are sudden leaps in ability as the brain has apparently been churning away at the problem in the background without any obvious deliberate effort in between.

I think we should be organizing education to expose concepts and tools early before people are “ready”, but not putting any particular pressure on repeated failure/struggle, and then trying again intermittently.

Instead we try to organize instruction so that each idea, tool, or method is taught once, with students encountering something new for the first time and being expected to understand it through short-term brute effort and punished if they fail, and then often a concept or idea is subsequently left aside and not revisited.
Confirmed by the German defence ministry, first reported by Speigel who seems to have a copy from the internal report on it (they are citing passages from it in their German article).

But I agree, it is highly dubious. Not having been involved, my only theory right now is that the supplier sold them to someone els. if he ran delivery himself, it is easy to route it through Kenia. Then the shipment get's lost. If he was smart, he has proper insurance for it.
