Am I the only one left with a befuddled feeling of missing context when it comes to particle physics? Like what does it mean for dark matter to be axions? "What's a quark?", Etc.

I feel like I have a context for understanding electrons and protons. I have read A Brief History of Time. What do I read next in order to have this article not sound like mumbo jumbo?

I sent this article to a vaccine researcher I know, here are his comments (I have his permission to share this):

TLDR the virus mutates too quickly for this to be safe.

" There are many ways to make vaccines, and the oldest one is to take the wild-type pathogen, and either ‘break’ it (‘attenuate it’), or find an example in nature that’s messed up and can’t cause disease.

The initial smallpox vaccine was cowpox: Close enough to human smallpox that it elicited protective immune responses, but too maladapted to humans that it couldn’t thrive in us, and would be caught by the slow-walking cops of our immune system.

The strategy used for many of the 1950s/60s-era vaccines was to isolate the disease-causing pathogen, then in a laboratory force it to grow in progressively more-messed-up circumstances. This would drive evolution of the pathogen to mis-adapted freaks. For example, the mumps isolate was from the daughter of the Merck scientist (Maurice Hilleman), and he grew it in cow cells, then lizard cells, then insect cells (or somesuch, I don’t know exactly). By the end of the process, the thing could still infect humans, but just BARELY.

Nowadays, with molecular biology, we can rationally design the ‘attenuations’, and do knock-outs or modifications.

Which brings me to low-virulence wildtype isolates of SARS-CoV-2 (S2): The root problem here, as with HIV, is it’s a super-fast-evolving RNA virus. Sure, a particular isolate might be low-virulence NOW, but give it a few weeks on a cruise ship and – viola! – nasty bugger ahoy!

When SARS-CoV-1 broke out, years back, it had a high lethality and freaked out the public health experts at the time (in fact, we were writing proposals to get into the research, but then it got contained). At that time, efforts were initiated to make a vaccine, based on the observation that all that was needed with the Bcell production of ‘neutralizing antibodies’. This is the long standard, matching most existing vaccines. So it was a low-weight lift, for vaccine developers (relatively easy-peasy). The project got pretty far along, but then stopped when SARS-CoV-1 disappeared as a threat.

When MERS, then SARS-CoV-2 came along, they resurrected the previous, promising design, based on a slow-evolving vector. But in the case of S2, they discovered that the targeting receptor usage of S2 was significantly different, so the design required a significant re-tune. Even so, the Chinese (I think) did it, injected the first people several weeks back, and I don’t think it works well (too early for formal reports).

S2 is nasty, as HIV is. It is using evolution against us. And because its hypermutable (like the influenza viruses), it’s going to be nearly impossible to make one vaccine that works cycle after cycle. It will continue to evolve, but the subsequent cycles will probably have lower lethality than this first pass (which was completely novel to the human immune system, so we had no ‘herd immunity’ protection). Going forward, it will be hard for highly-virulent forms to transmit if they kill their hosts too quickly, which will select for less-virulent forms.

The trick is to stay alive during this pass. The only mechanism we have to do this is to not get infected. The only way to do that is to not expose ourselves to infected people, or the things they’ve touched.

We’re back to how things were in the 1800s. Better than no science, but about the same as post-epidemiology/cell-theory-of-disease (1890s)

But as I said, this vaccine should be RELATIVELY easy to develop. It doesn’t have to be perfect, it just has to blunt viremia (so that the global pneumonia it causes in your upper/lower respiratory system doesn’t cause aveoloar collapse. In other words, even working a little bit will probably massively lower the death count.

But even an easy-peasy vaccine will take 18 months. There’s just no getting around that, unless you want to inoculate 5 billion people with something that might make the pandemic worse."

Does anyone know if there are any published stats / estimations about the prevalence of amphetamine prescriptions in the United States.

I have this gut feeling it's pretty high, at least in the tech industry. I don't believe this is problematic but it feels like a taboo topic. If use is common we should be better about talking openly about it.

The Uyghurs getting put in political reeducation camps.

Look into "kmonad", it is designed to bring the features of the QMK fireware to any keyboard on a Linux system. It is better than xmodmap IMHO.

Try "kmonad" for a Linux karabiner replacement. You'll need to follow some instructions on the GitHub readme but it can do what you want to do.

I love this and it makes me feel both excited and scared since I am suddenly realizing the ways my org is not in compliance with this good advice.

Are there any good books that are full of more rules of thumb like these?

Yeah I must echo your sentiments wrt their Google Now product, it is great. Not only does it provides relevant content but some of it is very new and or obscure which I really appreciate. I have linked people to videos I pulled off my Google Now feed and they are amazed that I know about a video on our very specific shared interest that is less than a couple hours old and has only a few hundred views.

Oof the circumcision topic, this is one where everyone argues for however their own personal penis looks and reasons backward from that.

I feel the same way especially if the laptop is in my lap.

This website rejects long passwords and provides the message "your password must be at least 6 characters" when doing so.

Otherwise, cool. I signed up.

Or do people with "superior general knowledge" recognize it is socially advantageous to present as humble?

IT runs on Java 8. IT in 2030 will not run on Java 8.

Article quotes someone making this claim: > we discovered that even if commit histories are rewritten, secrets can still be recovered…. we discovered we could recover the full contents of deleted commits from GitHub with only the commit’s SHA-1 ID.

Do repo cleaning tools such as https://rtyley.github.io/bfg-repo-cleaner/ leave the original commit's SHA-1 ID intact?

I think part of it is the context that JSON and XML are used in, particularly the era of software that uses these formats for configuration and the design implications that has.

Recently I've had to work with XML config files for a tool called Oozie, which is a data pipeline scheduling tool within the hadoop/spark ecosystem, and it has been soul crushingly tedious for me. Everything feels verbose and opaque, the documentation seems to prioritize enumerating every possible configuration option over providing minimum viable configs for common use cases.

JSON configs often just feel more simple and developer friendly. I'd say this has less to do with technical differences between JSON and XML and more to do with how "modern" software systems have been designed to be more ergonomic for developers/administrators and these modern systems happen to be more likely to use JSON.

It's also fun to hear non-technical people at work talk about "Jason files".

Because people are used to their brand and app? Good point.

Since Uber is about to ipo I have been hearing people question, "How can people highly value a company that is losing so much money???"

The reason is (the potential for) self driving cars. Once/if there is mature self driving tech, they can eliminate the cost of having to pay human drivers. When you consider Uber in that light, as long as they don't run out of money before self driving maturity, then their high valuation makes sense.

This may seem obvious to some but this fact has been entirely absent from every conversation I have heard about the valuation of uber's IPO ( looking at you Marketplace's "Make Me Smart" ;). It seems like it is taboo to point out that Uber needs to eventually eliminate all their human drivers from the equation.

Mostly unrelated question related to banks, does anyone know of banks that expose an api that owners of consumer checking accounts can use? Specifically to do things like read balance and recent transactions. What banks make this easy and have good documentation?

His talks are great, I have listened to hours of them. He is pretty funny too.

The teachers' situation is more demoralizing for sure.

Capitalism would explain the difference between a tech worker's pay and a teacher's pay as based on skill and worker scarcity, not on who works the hardest.

My brain briefly interpreted 'Gulag' as 'Golang'.

Just use a large stainless steel pan

Mersenne primes can be written as: 2^(some prime) - 1. Is there a name for the primes that can be written as: 2^(some prime) + 1?

I am shocked by how many people use 3d printed parts in the kitchen, printed PLA is not a food safe matieral.

And if you print a toy for your kids it's gonna end up in their mouth at some point...

Breaking crypto makes for a good headline but the most important application of QCs will be simulating quantum states, eg modeling molecular interactions. And obviously there is plenty of work that remains to be done in this nascent field.

Also obligatory link to the best quantum computing blog out there: https://www.scottaaronson.com/blog/. Very good at dispelling hype.

Are you by chance reading "The Master and His Emissary"?

Yes buy a second phone. What better way to be more present in your daily life?

Cool! Kinda like d3 but without javascript.

Those people usually grow up to run banks, or become CEOs of multinational conglomerates.

Got a citation? I imagine most people like this would end up in prison and/or socially marginalized. Being incapable of empathy is basically a disability.
