N95s are still quite difficult to find here in the US.

Cloth and non-medical disposable masks are not considered protective (although it's likely they block some inbound particles, and there's evidence they may thus result in a gentler illness on average) but do reduce transmission.

You're right that there are multiple kinds of masks; in the US, it's kinda pointless to talk about N95s. No one's wearing them, in part because they're hard to get, and in part because our anti-maskers threw enough of a fit about fairly comfortable ones.

> The other issue you miss is that there really has not been good evidence of outdoor transmission, and the claims of covid living on outdoor surfaces for 7 days also are suspect.

You'll actually find me elsewhere on this thread noting that outdoors tends to be safe, so I'm not sure what statement of mine you're arguing with here.

I... think you may have some reading to do. The subject is pretty well studied.

The main reason FPTP ensures at most 2 parties is that, say you have parties 1, A, and B, where A and B are relatively similar to each other. And say A and B are together more populous than 1, like a 40/30/30 split.

By splitting those 60% mostly-similar votes between A and B, both lose to the less-popular 1. It becomes in A and B's best interest to not cannibalize each other's votes, i.e. merge and dominate (or at least compete). The less fragmented ideology wins, not the most desired.

It's even more compelling during the formation of new parties when there are only 2: by not voting for one of the two dominant ones, you are literally throwing your vote away because it has no chance, and it's worse for your ideology than if you had chosen the most-similar of the dominant party.

My 2 cents is that they just have different methodologies driving them. Sia is shipping a working network early and updates are arriving often.

Filecoin seems to be taking an approach more like Holochain stuff. Meaning they are shipping early and often but only internally and you'll get to see it when its ready™.

> ICEs are real technology

They are real technology, in the sense that this is where over 100 years of optimising every aspect of ICE has got us to. Fascinatingly complex, extremely well engineered, and depending on the brand still relatively likely to break down within the first few years.

The engines are also longer designed to be maintained without special processes, and are increasingly designed around emission regulations. To the point where a lot of the complexity is in emission systems and the cars are choked by their own extremely lean fuel maps.

Electric motors on the other hand are still relatively unoptimised and the potential in things like torque vectoring is amazing. I'll miss driving manual, but it's getting just about impossible to buy those now anyway.
Marjane Satrapi's awesome autobiographical comic "Persepolis" [1] also addresses this as the setup to the chain of events that would lead to Iran's current theocracy.

I do like fast.ai for a lot of things. Their video production is very, very lacking though. I’ve tried to watch some of their DL courses and really they’re about as good as some stogy old non-tech savvy professor attempting to make an instructional video. Lots of echo, sound coming in an out, basically filmed from the back of an auditorium, etc. I can’t comment as much on the content as it was hard to get through. Some MIT OCW courses are similar. But from the fast ai content I’ve read, it’s very good.

An example of well done video is an Andrew Ng Coursers course. Great sound, great pacing, easy to follow like you’re on a zoom call with him directly, etc.
> Yes, there are some circumstances in which labor ends up more concentrated after a minimum wage hike, but other circumstances in which that is not the case.

But that's what I'm saying. Minimum wage is ridiculous because there are alternative policies that don't do the bad thing at all, not even sometimes.

It's not price fixing nor collusion. It's just the incentives companies have to lower wages.

Look at this example: a number of companies in an area are paying a livable wage at time T for low-skilled workers. Now, time goes on and inflation kicks in. Those wages, which did not grow, are not livable now. Workers, however, can't complain too much because they will be fired, and bad income is better than no income (not to mention healthcare tied to the jobs). There are also more workers than job positions, and new young workers are constantly entering the market, so companies will always find someone that needs to work even at that low wage.

What incentives do those companies have to increase wages? Absolutely none. In fact, this is what is happening right now.

> Without price fixing and collusion the employers have to compete for labor.

If employees actually had to compete for labor in all cases, we wouldn't be having this debate and people wouldn't be complaining that their wages are not enough to live.
Here's how money works on people:

Step 1: They get an credible offer for a ton of money.

Step 2: Their brain starts to spiral out of control and can't stop imagining all of the things they can do for themselves, their family, their friends, the world, etc

Step 3: They've just created millions of incentives for themselves.

It takes a very strong person to drive out the biases that money creates in our brains. Monetary incentives are the strongest bias creators, beaten (probably) only by sex and blood (i.e. family relations). Breaking them is the work of an iron will. You had better assume you'd do no better.

> In a capitalist society, that worker's wage is determined based on the value of their contribution and the supply of workers with the requisite skill.

I think we need to define "value of their contribution".

If a friend of mine has an idea for an app, but he has zero programming knowledge and so he pays me $1,000 to develop it, and he ends up making $1,000,000 from selling it, what is the value of my contribution?

Is it only $1,000 because that was the agreed price for my labor? Or is it $1,000,000 because that's how much money he made from it? Or something in between?

Obviously, in this hypothetical, I should be negotiating a share of the revenue instead of just a flat fee, but generally most workers don't get to do this.

So...what was the value of my contribution?

Because it has substantially more poly-unsaturated fats. See this graphic for info: https://cdn.mos.cms.futurecdn.net/4DmwKT6rrQf2BMJQwvX2cX-650...

It's not really that saturated or mono-unsaturated fats are good for you, but that poly-unsaturated fats are bad for you. I realize this is contrary to what much of modern nutrition says, but the lipid science says the poly-unsaturated fats are worse because they react more with other molecules in your body.

Also, saturated fat consumption has been declining and unsaturated fat consumption increasing over the past decades while health keeps getting worse. To me, this suggests that something is wrong with our current nutritional understanding, and I believe the lipid science shows that the problem is the poly-unsaturated fats (as one part of it at least, it's obviously not monocausal).
I’m part of some online fitness communities and it’s insane the rationalizations people will use to go back to the gym. I have even heard of people driving 3hrs+ or staying overnight to go to out of state gyms with less restrictions. Which is actually very terrible on a macro level.

That said I do think it’s possible for gyms to adapt to be covid-safe by moving equipment outside, restricting the max number of people allowed in the exercise area, mandating masks and social distancing, and wiping down every piece of equipment after it’s used. I have seen some gyms doing that in San Jose. But I guess most gyms don’t want to do that even though gyms outside of dense urban area typically have pretty big parking lots they might be able to use with some open-air huts
This assumes that ML and AI research will continue to be silo'd outside of domain specific research. But it's not the case in academia and also increasingly in industry. You have computational neuroscience, bioinformatics, and many other traditional disciplines which have not only incorporated ML/AI methods but also pushed the fundamental methods research forward. We're increasingly seeing interdisciplinary methods and research becoming the norm in academia. In undergrad, nearly all the social science classes and all the hard science classes had some sort programming and quantitative methods requirement. Even in industry we're seeing interesting multi-disciplinary work.Many interesting innovations in time series ML methods have come from the algorithmic trading firms and medical research community has made contributions to computer vision and unsupervised learning approaches.

I had a colleague who during her PhD in particle physics wrote from high performance parallel computation frameworks from the ground up in C which was better than Hadoop and Spark in performance. And at my last enterprise AI startup, our CTO had come from a computational neuroscience background. Whether these folks end up in creating startups is a different question, but the talent definitely exists.

The more difficult problem is how to evaluate multi-disciplinary startups and businesses. There usually isn't good empirical evidence unless they follow a more established business model.
> The only way to counter that push is by giving more power to the worker, and in low-skilled fields with lots of available workers, you need to do that through regulations and subsidies.

Even assuming everything else you've said is true, that's quite the leap to make. And also quite the oversimplification. There are lots of regulations and subsidies that have been tried where the unintended consequences end up negating most of the benefits, and just turn out to make the entrenched powers even more entrenched and wealthy. Plus there are ideas like UBI that don't fit neatly into the traditional buckets of "regulations and subsidies" and could be another (better?) way to give workers more leverage.
>That could theoretically increase unemployment in some industries with razor thin margins, but it's far from a given.

It's not a given when you're talking about a small region like Seattle. However, increasing the minimum wage to the entire US would dramatically increase unemployment in the poorest areas. The minimum wage is why territories like American Samoa and Puerto Rico have the highest unemployment.

Edit: changed Guam to American Samoa
Great observation. Thank you. I think there is a middle way, but it's not so much about definitions as about balance. There's a time to sow (work) and a time to reap (rest and enjoy). Of course you have to sow before you can reap, but if all you do is sow then your final yield is zero. You have to alternate, maximizing the product of the two instead of either alone.

It's just not as simple as "companies have more power in negotiation". At times, it can be. But usually, it is a more complex interaction.
How much inflation could we have? The only people getting more money right now are the super-rich and the most poor. Lots of middle class / working class can’t work or earn money and those are the people that drive costs of anything we care about.

Is there some deeper meaning to 1 + 1 = 2 you could enlighten us on? Most teachers I’ve met seem perfectly capable at getting at least that across.
Kindergarten in the US became far more academically focused after the No Child Left Behind Act of 2001, and the adoption of Common Core curriculum. Most schools also changed the age cutoff date for kindergarten so the average student is now slightly older.
I pulled my teenagers out of 'classroom' oriented school so that they can just do self-paced online courses instead of risking a repeat of the disaster from last semester when their school tried to do 'distance' learning with zoom meetings. I can't imagine a five year old doing well with this.

How does that work? The idea is to just resume schooling where you left off a year prior. In what way can anyone get ahead? Kids who didn't pause would simply be in a higher grade, others in a lower grade, but so what?
> I think health professionals lost a megaton of credibility in claiming masks don't help, to not wear masks, or that masks can only help reduce transmission not infection. Other countries went all out on masks - with great results.

I think for the most part health professionals answered specific questions about specific types of situations or types of transmission, and the media runs with overly broad statements when are then pushed/rejected by different parties.

There are many inputs that go into something as simple as a recommendation of "should the general public wear masks", including "are there enough masks for health professionals currently", "what's the current infection rates", "how far has it spread", "what type of masks". Additionally the answer might be different at different times in the past depending on whether talking about a locality with an outbreak or the whole nation. Expecting the answer as to whether wearing a mask to help to not change over time is as silly as expecting it to not change pre-COVID-19 start and after it.

The bottom line is that the inputs that influence the recommendation are fluid and change over time, so we should expect the recommendation to change over time, and the only reason people aren't getting that is because it's in the best interest of different groups to position it otherwise so they can use it to score points (and while the obvious groups in question are political, they aren't limited to one side of the spectrum, this is a common tactic used across the board which is particularly troublesome when it attacks the credibility of the people we trust to tell us how to protect ourselves).

How Hackers Bled 118 Bitcoins Out of Covid Researchers in U.S.
I don’t have a clear number for many. But the hospitalization rate is 1-2 %. And if we assume that half of them have long term symptoms thats around 1 %.

You can do one thing to reduce your viral load. Wear a mask. N95 will do better than a surgical mask. But even mask wearing seems controversial. These things are really hard to study so you need to err on the side of caution.
To play devil's advocate here:

Yes, with UBI we're basically taxing ourselves to pay ourselves, it will hurt productivity and will cause inflation.

But at least in a country like Germany, where I live, that is already happening for decades via our ever-growing, convoluted, amounts of government welfare programs, subsidies and redistribution schemes.

A UBI would then at least have the benefit of cutting out the bureaucrat middle man.
Yes and I’d even go so far as to say I‘m not sure the “screen” really has much to do with the difficulty. I had a hard time sitting and paying attention in class 25 years ago. All of my teachers “solved” this by putting me in the front row so they could keep an eye on me and remind me to sit again. But my 3rd grade teacher gave me a desk in the back row so I could sit in my chair, sit on my desk, or stand without bothering the other students. It turned out I could pay attention when I wasn’t forced to assume the learning position.
That's all fixed for this year's courses. (This is the first of this year's courses to be released.)
I think I read this exact comment from my aunt on fb yesterday. She said 3 in 100 though.
We started using it around 2016 in the company I work for. We decided to use it to automate the often manual setup of new clients for each product. It grew to use our own security and rights system, and we also added a different database support (which we are working on the open source). We also changed the Jason API to conform to our company wide standard.

At the time, we wanted something that we could host ourself, maintained, open source and that was working!

Nowadays internal teams also use it to automate their own processes as well.

We’d probably go for a “push based” workflow engine, maybe based on events, mainly for latency and load reasons, but it’s something we’re ok with so far (there is a way to listen to event for some tasks though, but it’s not that easy)

If I’m not mistaken, Netflix uses it to automate video encoding for shows, but that might be outdated.

Overall, we’re pleased about it.
But here are some cons about it: we wished we could split some services out (such as read only ones, or the workflow definitions from the executions, etc, but the code isn’t architecture for such an easy split: for example, pushing the result of a task computation by a worker triggers the current workflow to determine the next task to schedule, but it’s doing this internally, and not through the defined interfaces)
Security of the api is not so easy, as it’s not really modular (unlike the database implementation, which is great). That point is being worked on though, so there is some hope for the future.
We were extremely lucky to have a great K teacher who really wanted to work with us and our son to help him through his difficult time adjusting to school. We worked with him quite a bit, and by the "end of the year" (i.e. spring break, when lockdown started), he was processing his feelings of overwhelmedness much better, and going to her (and just collapsing into a heap in her lap) when he felt overwhelmed.

Compare that to a friend's son, who is the same age as ours but has some developmental delays of some type (I assume). Their teacher told them that they had to "get this dealt with"; in other words, "fix your kid so I don't have to deal with him". Not exactly a welcoming and comforting environment for a child who needs to be met halfway.

I mentioned this anecdote to our son's teacher and her first comment was "wow... is she an older teacher?" And yes, she was. She's been working with kids for 30 years, probably isn't as flexible in terms of learning strategies as younger teachers are, and, probably even worse, has been underpaid (and under-respected) for that whole time, so she's surely just burnt out and waiting for retirement at this point.

Maybe if teaching paid decent money we'd have more teachers who could put in the time and emotional energy to nurture their students, rather than just putting them through the pipeline, and who wouldn't get so cynical and short-tempered by the end of their career.
If you're still reading comments :-) I remembered a few other things Les Mills does that are great.

They have a lot of training videos, several for each class of exercise they do. They're in-depth, and really show you the form.

They add tips to the actual work-outs, so you're constantly reminded of good form.

They have alternatives to most of the exercises, so you can modify them if you have (e.g.) knee problems, or aren't up to full push-ups, etc.

They do good cool-down routines at the end of most videos, and have a number of cool-down-only videos you can watch for the others. Not everyone thinks highly of post work-out cool-down/stretching, but a lot of the people who seriously study exercise recommend it.
