I wasn't first in line to get any of these vaccines. Distrust of anything new is pretty rational!

But hundreds of millions of doses delivered, with a complication rate significantly less than the disease itself... that's pretty powerful evidence, no?

Especially compared against drugs that have yet to convincingly beat placebos in any large trial?

Personally, I find it bizarre that anyone can weight those two sets of evidence so differently.
I remember that the guys behind The Pirate Bay actually made a service like this back in the days.

Even if you find all those multiple number of volunteers, you still need additional vaccine doses to be manufactured, which can take longer because they need more supplies from third parties, and scale up early. Not to mention all the extra staff to run the trials.

If somehow they're able to run trials on 12x the volunteers, I would rather that they increase the participants by 12x for the final dose so that you get more confidence in the Phase 3 study results and in finding rare side effects.

not sure how 'little-known', but...
Anyone know if this has implications for P=NP, where they’ve found parallels between phase transitions and the “danger zone” of NP-complete problems?

Background: for the NP-complete 3SAT (Boolean satisfiability where the clauses all have up to 3 terms OR’d together), there are ratios of clauses to variables that make instances trivially satisfiable or or trivially unsatisfiable. In between them are the hardest cases, where you run into exponential time blow-up. That transition is analogized to phase transitions in matter.
When I found out about this, I wrote some macros to replicate some of the semantic of ISPC [1] in C++ as a fun experiment [2].

> So much time has been spent on making C something that it’s not.

GObject is a great example of this. It's a library for doing OOP with C, rather than switching to C++. It's clunky enough that they ended up making a whole new language which compiles to C/GObject, called Vala.

Vala rarely gets attention these days, but it's worth reading about. https://en.wikipedia.org/wiki/Vala_(programming_language)
The difference is that in that trial they weren't looking at health outcomes. They were looking at people's blood and measuring antibodies.

If it turns out that 25mg produces a small amount of antibodies - but that small amount is still more than enough to prevent the same number of hospitalizations that 100mg does - then it make sense to go with that.

The dosage trials were only used to study the microbiology. Not the death/hospitalization outcomes.

It's probably not worth the effort providing any form of defense of any part of Musk's role in this, but his team did ask the British lead divers whether they should carry on working on the sub (well, underwater transportation tank) project, and they received the response that the lead divers wished them to continue as a contingency.

Also, one should obviously not falsely accuse someone of being a pedophile, including if they tell you to shove your submarine up your ass.

But really, this whole thread shows up every time the cave story is mentioned, and I think the whole thing just detracts from the fantastic international act of heroism that the rescue was.

What?

The UDM Pro[0] has a quad-core Cortex A57 CPU running at 1.7GHz, according to the spec sheet I'm looking at right now. It has 4GB of RAM.

The ODROID-N2+[1] has a quad-core Cortex A73 CPU running at 2.4GHz. It also has 4GB of RAM.

The UDM Pro is like half the performance of the ODROID-N2+, accounting for architecture and frequency differences, so... I'm not sure what you're getting at?

The ODROID should be more than enough to handle a gigabit connection if the UDM Pro is even halfway capable of it, from a power perspective. Connecting more ethernet ports to it without an exposed PCIe connector is going to be clunky, but that's not the issue you pointed out.

“Before the war” if you will haha - as in before COVID, which has distorted at least my perception of time greatly.
It doesn't matter whether your justification for why this should happen is altruism or selfishness, the same problem remains: a vaccination program of the scale and speed we've already seen is literally unprecedented, it's astounding that everyone managed this much, and yet even with that incredible effort there still aren't the doses to vaccinate the planet any time in the imminent future let alone the on-the-ground infrastructure to deliver them everywhere - and even the rich, developed countries with the best vaccine rollouts out there probably haven't reached herd immunity before new variants made that impractical or even impossible with the current vaccines.

This isn't that remarkable. Previous attempts to deal with respiratory disease pandemics using vaccines have proved pretty futile, even though it is a standard part of pandemic planning.
mRNA vaccines have extreme cold storage requirements that make it very difficult to distribute to many places in the world.
I don't understand why anyone has an issue with that. You know what else can copy and paste code all the time? Humans. But we have various ways of stopping employees who copy and paste code from stackoverflow and github without checking the license, so it's the same thing if you use one of these tools. There's nothing new I can see here to be upset about.

This would be a lot more interesting if it showed the various GPT-3 experiments at generating music and used that as a point of comparison.
No, you really don't. Though the problem in this case is the N2 only has 1 GbE port and adding more through USB, even 3.0, is notoriously bad (regardless of the platform.)

I've been playing with genetic algorithms for years now as a hobby and this type approach was a dead end for me, the GA entities would just "game the system" as it were and would min/max in surprising ways.

My latest genetic algorithm creation https://littlefish.fish has performed far better at pattern recognition than I expected. I really think they've got massive potential.
For a lot of tasks, posix-compliant Bash scripts are more than adequate. Use Perl, Python, or Ruby (your choice) if it becomes more complex (especially with state). It’s worth considering ones that are installed by default on most linux distros.

"probably centuries away"

Making technological predictions on such a timescale is folly.

1821 is two centuries away - the minimum necessary to use a plural form of the noun "century". For a person of 1821, the technologies that we rely upon routinely would be completely unknown. What would they recognize? Not cars, not computers, not electrical appliances and light, not pretty much anything in our households save furniture.

Of all the tech that you can meet in an American street of 2021, the only thing that would be somewhat familiar to people of 1821 would be guns.

But remembering it long enough to get away from the person who told them the fact and then ask a different person... That's another story. I'd think far too much would be happening for them to bother remembering to ask.

Being able to look it up independently of another human makes it a lot easier to verify information immediately, so I'm not surprised that people who can read are more likely to verify info than those who can't.
Note the Atom C2xxx series is the one where Intel f*cked up the LPC bus I/O drivers and it dies after a few years. Don't buy them used unless you're comfortable soldering a resistor to a clock line to extend its life.

Are you saying that my use of "clear feedback" isn't accurate? I mean this with respect to what was in scope for phase II, although I could see an argument against using that subjective language. Also, even more dosages were tested in phase I, again on a few number of people, but I'm not sure if that's different from how it's usually done.

> The important thing for the vaccine was too limit death and hospitalization. And phase II didn't tell us clear info on that.

Phase II is primarily to test that the "candidate is safe, sufficiently immunogenic, and maybe protective"[1]. It's not clear to me that testing hospitalization percentage is in scope.

The current phase 2/3 trials Pfizer is doing for children under 12 is using a 1/3rd dose for 5-11 year olds and 1/10th dose for 6 months to 4 year olds, based on an earlier phase 1 trial.
The risk is that even if that lower dose with a lower antibody response works fine with existing variants, it might not fare so well against future mutations. I think this has already happened to a certain extent with the currently circulating variants - vaccination programs that gave worse antibody responses fared OK against the original variant, but not so well against newer ones.
> They used a new nanofiber membrane distillation process that could desalinate water with 99.99% efficiency.

The article doesn't say much about the process, but it seems like membrane distillation does involve water vapor in some way: https://en.wikipedia.org/wiki/Membrane_distillation

> Unfortunately, reverse osmosis uses a tremendous amount of energy, and in the process of desalting water in this way, harmful waste is generated, which is usually discharged back into the sea or ocean.

I believe every desalination process, including this one, inherently needs to discharge salty wastewater back to the ocean.
Correct, if you uncomment

in blitsort.h it'll run about 25% faster. Probably still slower than a native C++ implementation since it'll evaluate to (a > b) > 0 rather than (a > b), not sure if the compiler will optimize that.

I had an interesting experience, I did electronic engineering but i completely misunderstood how to solder - i was trying to melt the solder onto the iron and drop a drop of molten solder on the board with the wire. The technicians were laughing their asses off and said "if you cant solder maybe you shouldn't be here"

It was in 2nd year when I watched a youtube video when some guy actually explained thay you need to heat up the pad on the board, then add solder. I was totally flabbergased.

Soldering was a very minor part of my degree, so it didn't really matter, but still.

I think that is fair but I also find the status quo bias strange.

If you think that variant changing is a bigger deal than getting them out fast what makes you so sure we shouldn't increase dosage another 50% or another booster?

Right now it seems like the mRNA vaccines work fine and the variants are actually getting better at spreading but not killing.

> For every 40 pounds of 90°F/90% RH air that you want to make into comfortable inside air:

That's a worst case scenario, though.

For one, 90/90 would translate to a 87F dew point -- which is not a record, but it's pretty close, and there's a good chance it would be lethal to unprotected humans. So it does not happen too often, e.g. normal in a place like Phoenix Arizona might be 110F but 20% RH.

Second, air conditioning doesn't cool outside air, it cools inside air. So on average it isn't going to have nearly that much water to pull out of the air.
Or perhaps because the intuitions of pre-school-aged children are still forming; there's a lot they don't know, and the world is new and exciting, so scepticism would mostly just rob them of learning opportunities.

There aren't any special "bulk" interfaces at the moment, you can load data via a small program using our language bindings (INSERT in a loop). We'll add support for batched `executemany()` soon to cater to very large loads specifically. A similar optimization in asyncpg [1] led to a 10x improvement in throughput (~100Krec/sec per connection), and we expect similar performance from EdgeDB once the protocol and the bindings are updated.

Loading arbitrary JSON by introspecting the data, and auto-generating the schema and the necessary DML statements is fairly straightforward too. I have a rough Python proof-of-concept, will need to find time to finish and publish it.
