Is there a good discussion anywhere of the anticipated impact in effacity on various choices around privacy here? A simple toy model for the fraction of infection chains stopped might be something like

fraction stoppped = (usage fraction in population)2 * (fraction of infections recorded as contacts) * (fraction of detected contacts who follow up correctly)

That's obviously a massive over simplification; for example real population dynamics don't give full random mixing between all members of the population. But every factor there is potentially depressed because of opt in and anomnymity; the first obviously so, the third because people are less likely to followup correctly if there's no consequence for not doing so, and the second because it will be impossible to tune the detection parameters without any data to work from. In that — again oversimplified — model if you get 50% o the population using the app (compared to 80% smartphone usage in western Europe), it detects 80% of transmissions and (say) 50% of people follow up correctly before themselves passing the disease on, you end up with 10% of infection chains traced. That doesn't seem like it's going to have a big impact.

So assuming that model's not wildly wrong — which it could be, again, I'm really looking for a link to an expert discussion of this, I can see a few possibilities:
* Digitial contract tracing doesn't have much impact on our ability to control the virus
* Governments seek to outsource the privacy-invasion needed to companies by e.g. requiring evidence that people are using the contact tracing software and have followed up on potential transmission events before allowing people to buy food etc.
* Ineffective opt-in contact tracing and a second wave of pandemic deaths/lockdown is used to bounce people into accepting the need for mandatory, non-anonymous contact tracing with fewer privacy concessions than you'd get right now.

To be clear I'm very concerned with the idea of govenments and in particular the current UK government having access to non-anonymised contact data; it's already being run by someone who considers population-level manipulation using data science and social media to be his core skillset. But I'd also like to understand what tradeoffs are being made in terms of disease control.

I have a different perspective and experience.

Ads have enabled me to access information at little to no cost to me. Ads enable us to search the Internet.

I learned to exercise, eat healthy, and much more from watching YouTube. I’ve learned a lot from newspapers and blogs. I’ve learned a lot from people on Twitter. Do I enjoy advertising? No, usually not. But from my perspective it’s a win-win. Companies promote their products and I get to read things for free.

Look on the bright side.

Nobody mentioned Ada/Spark yet? This is doing exactly that, but in a real programming language, not with a seperate proof system. You only write code once.

Use widely in the industry.
With such a system you can also generate test cases automatically to verify the assertions. Such as with cbmc for the C language if one cares, and the manager doesn't trust the proof system.

> 1) Friend from college working in machine learning space who just moved back to SV from Asia, saying that the tech culture in Asia suffered from a lack of creativity. In the same conversation I brought up having used psilocybin and he freaked out, thinking it was going to damage my brain.

Doesn't that re-enforce the conditioning the CCP is capable of even within its supposedly 'creative, disrupting innovative' cohort in China? So after being immersed in that environment it ensures the thought of a substance that induces deep, critical and often very uncomfortable introspection and potentially painful moments of clarity is thought to melt your brain? I'm not at all surprised by that occurring if I'm honest.

I may talk negatively about the many ills of SV but at least its forward thinking enough that you can just go into the East Bay into Oakland and be where its completely decriminalized now. There is something to be said about it being 'accessible' enough if you're actually really motivated, all while it not being so widely shoved down your throat with perpetual ads and aggressive marketing. I'd hate to see Psilocybin analogues as plentiful in 7-11 as 'spice' was (synthetic canabinoids).

Personally, after being in the Industry and seeing how MJ played out I kind of hope it sticks to a MAPS like model where its left in the hands of researchers and medical professionals on the Establishment side, and simply de-criminalized on the Public side. That's the best of both Worlds I think and restores individual agency. But I want to make it clear: I think plant medicines are no joke and not to be taken at all lightly, this includes cannabis.

Hopefully we get a kickstart in future mycologists and explore other usecases from it while its still a DIY system. I was listening to an NPR story about a lady who decided to try and build a 8ft canoe entirely out of mycelium, just because she wanted to see if it would be sea-worthy [1]. I thought that was pretty cool in a bio-hacker kind of way.

As for your experiences, maybe expand your social circle?

> At the risk of getting downvoted I just gotta say: I think you're talking to the wrong people...

My thoughts exactly, no downvote from me. And incidentally only then did I look up at his handle and kind of just nodded to myself.

I personally think we're at the same place where MJ was in the mid to late 90s depending where you are; its out there and people do it in private but good luck getting them to admit it to you with all the blatant propaganda and misinformation if you're not included without overtly asking about it. Oddly enough, CU Boulder has a psychedelic club on campus [2]; I never went to a meeting myself, unfortunately but I heard good things from an Educational stand point.

I talked to a guy I only just met on my way to SFO from DIA about psychedlics the last time I went to NorCal, we were talking about what we were doing at work, then the weather and environment and the ever growing harshness of the wild fires in CA over the years: it just came up naturally.

Coronavirus hits the Global South – The disaster facing poorer countries
"And given that it’s 2.5 million light years away, the surprising amount of sky space Andromeda takes up speaks to just how ridiculously large a 140,000 light year diameter galaxy is."

Well, not really. I mean, that doesn't tell me anything about its hugeness, because apparent size is based on a ratio. They're making a ratio with light years on both sides, so they effectively cancel out. 2.5 million / 140,000 is 17.8. So Andromeda is only 17.8 times as far away from us as its diameter. (which is, to me, a very interesting takeaway)

You could substitute "millimeters" for "light years" and it would appear the same size, i.e. a 459 foot diameter object that is 8200 feet away would have the same apparent size as Andromeda.

Not trying to criticize the article, but thought it was an interesting way they put it.
Why do you think these conditions exist in Pakistan? Hint, it mainly has to do with the actions of certain Pakistanis. The rest of us are not "allowing" anything, we are basically powerless and irrelevant aside from maybe our trade policies.

The idea that humans evolve somehow into better beings is an unjustified religion. You shouldn't let technological progress fool you, we are nearly the same as we were 1 million years ago.

Raising domesticated animals for slaughter is actually pretty humane. Before agriculture and farming, when people moved to an area it led to the extinction of all large animals and they died in agony.

For many of us human life is much more important than the slaughtering of domesticated animals. This isn't about a God.

We evolved feelings, morals, the concept of cruelty in order to care about human life. You can choose to care about whatever you want of course, but careful with your priorities.

And yes, chickens aren't human and are quite tasty.
Frankly, I wouldn't be surprised if there was another meta-edit-war where someone exclaimed "Guys, stop, you are featured in _Lamest Edit Wars_ page!" and a lengthy discussion ensued whether being featured in the page implies the edit dispute was in "bad faith" (or whatever wiki-ism they use these days), and the disclaimer was a result of that.

I read the Happiness Hypothesis quite late in my development regarding "how to be come happier?" I already knew a lot of the ideas in there, but it presented its ideas a bit more clearly than whatever I read from Martin Seligman (many books) and Suzanne Segerstrom (Optimism).

This is why I'd still recommend that book.

I also recommend to read the concept on self-learned helplessness (Seligman researched it) if you haven't already.

One book that I actively disrecommend nowadays is Man's Search for Meaning. I didn't look too deep into it, but there's a lot of controversy on the truth of his claims (e.g. some claim he was in the concentration camps for a few days, not months or years like he implicitly depicts).

Disclaimer: it's these types of books that motivated me to do an entire undergraduate degree in psychology back 6 years ago. Only to realize most of it is nonsense. Yet, at the same time, not all of it is nonsense. Plus it gave me the skills to see what was and what wasn't nonsense.

The epidemic isn't "dead", in the author's words, until we stop having to take emergency measures to fight it. A plan that doesn't finish with "then we reopen sports stadiums and stop all social distancing" isn't a plan to end the epidemic, and social distancing is one of the author's five prongs.
Calling An Jung-Geun a terrorist would be akin to calling George Washington a terrorist.

You cannot decide everything by pure reason inside your own head without referring to the work of others, at which point you've made them an authority by deciding that they are credible.

You might be able to determine by critical thinking that bleach isn't a coronavirus cure, but chloroquine? You're going to have to wait for someone to run a trial and then decide if they're a credible authority.

Applying critical thinking to your choice of sources is both easier and more important than applying it to their claims.

Have you gone and verified some physical constants yourself, it are you just accepting authority as to the mass of the electron?

It is not necessary to resort to JavaScript for the emulation, emulation and interpretation are allowed. App Store effectively forbids the usage of JIT (so VMs do not run as fast as one could expect) and running any code that’s not included in the package at the time you submit the app for review (with an exception for educational apps).
That is one side of the scale. The other side of the scale has the meat industry in it (which is absolutely not like 100 years ago). As someone who used to work in a slaughter house, I am not convinced that today is better. I can see our children looking back in a few generations and think of us as barbaric. I thought of it as barbaric and surreal when working there.

Fermi questions[0] (oft maligned when asked in interviews) are a good practice for this sort of thinking.

Anything that is either out of range on scale, or that ducks the question, is worthy of further evaluation and at least some mild skepticism. Theranos promising hundreds of blood tests out of a thimble of blood would be the former. The article referring to Volts of electricity is like a car salesman replying to 'how many seats does it have?' with 'The seats are upholstered in Fine Corinthian Leather' the statement isn't incorrect, it is just useless and, in context, intentionally misleading. Salesmen do it to sell cars, scientists to sell research, journalists to sell papers, and conspiracy theorists for, whatever reasons, I guess.

I think chickens are ground up with their feathers and ugly bits by falling from a treadmill.

I guess one can't sell that as food but I'm pretty sure they can do something with it.

Although, it's fine by me, meat is in its nature pretty wasteful, in addition to those 2M chickens there's probably more tons of soy protein wasted on chicken feed.

Good thing that protein rich legumes do not need much processing.

Hey. Kind of same here. I’m a good programmer but not motivated enough to really get to grips with the difficult and low-paying fields I’m interested in. Here’s a lazy solution: cut down your hours. Work 4 days or less. If programming’s already so boring, then there’s not much downside to picking a boring well-paid field to offset the salary loss. Use your time to do things you care about instead.
The efficiency of wind turbines and their area for capturing wind goes up with size, so a single large one is better than lots of small ones. Which is why domestic ones have not become popular except off grid.
This question interests me as well, and I've done some thinking about it over the years. In particular, what I'm interested in is a hypothetically simplest object that can reproduce in a solution of simpler components, along with some differentiating characteristic. For example, maybe you have toroids that pick up particules, grow the torus until its too big, and then splits - and the ends of both halves click together, forming a total of two toroids. Another characteristic that very simple life must have (I believe) is some level of circularity in the sense that the element is an "accumulation of experience" - we might say a reduction of its environment. In the same way Schordinger was interested in life thermodynamically[1] I am interested in speculating about the simplest possible mechanisms in the beginning. (NB I'd expect none of these very simple machines to survive to present day - in fact, I'd imagine there to be several generations of early life, each obliterating/consuming/sublimating the ones before.)
