I was surprised to learn that the Airthings Wave Plus ($180~) doesn't measure PM2.5. It is cool that it does Radon and VOCs which this cannot do.

This seems like it could either compete OR complement an Airthings Wave Plus for like 35% of the cost. Since they both offer different and overlapping data.

I wonder what you'd need to do to get Radon and VOCs too in this solution (essentially match and exceed the Airthings Wave Plus)?
> Do we have a word for "imperialist government uses violence against people to achieve political goals"?

Yes, we call this "war".

No, it's not. Nobody is trying to dogde the bad aspects of the word, it's just that terrorism specifically is, by definition, not from a state.

This is not true. These people span the entire political spectrum, so it's not just those who watch Fox News. Not only that, I know a few of them who are vehemently pro-vaccine, so much that they won't even let their kids play with unvaccinated kids. The issue just isn't that simple.
Even an ideal blockchain-ified P2P "Web 3.0" is a silly fantasy on par with NAT-less IPv4. First they reinvented gold & databases, now they are reinventing IP.

Flat networks are a thing of the past, when you could keep the whole Internet in a paper directory on your desk. Blockchains may be used for settlement and accounting within small networks of international firms, but they will never service the latency and throughput needs of 8 billion netizens.
Yeah but that only works if you're compiling it yourself. LD_LIBRARY_PATH lets you get binaries working this way, at least sometimes.

No, it didn't go to the Supreme Court.

> "the phrase "shouting fire in a crowded theater" has become synonymous with speech that, because of its danger of provoking violence, is not protected by the First Amendment."

While the phrase may be used that way, its referencing nonbinding dicta (expressions in a ruling that are not germane to the decision rule for the case actually before the court) that does not reflect preexisting law from a case that has since been almost entirely overruled and is widely recognized as being an aberration that (in its actual binding holding) allowed extensive government regulation of core protected political speech.

It reflects neither the law before the decision, the binding case law created by the decision, nor the state of the law after the decision was rejected.
About 20 years of long-term safety data. How about we start with that before we even think twice about making anything mandatory?

It blows my mind that people only seem to be thinking about “does the vaccine kill you within a week”. That’s literally the least of your worries. How the vaccine affects your heart, brain, or reproductive facilities 20 years from now is what I’m concerned about. And I’ve heard nothing to address that concern. So as far as I’m concerned, until this vaccine has a track record as proven as measles, it’s still experimental and still worth being skeptical.

There's a name for it: Security Theater [1]. "Security theater is the practice of taking security measures that are intended to provide the feeling of improved security while doing little or nothing to achieve it."

Some have likened it to a jobs program that both increases the surveillance capability of the government as well as provides political creds for the representatives in those districts where airports exist, similar to the Military Industrial Complex.

Well, there are two groups roughly speaking of people with natural immunity. One group, those who have already had the virus, seem to be fairly well protected according to that one Israeli study. Obviously, going out and getting the virus to protect yourself from the virus is an idea straight out of Catch-22, so I assume you're talking about the other group. ;)

As for people with natural immunity but who haven't had it, that's everyone. Every person has what are called "naive B-cells," covered in random antibodies. One of them probably binds to coronavirus in some way, and that would be how your body would get started fighting the infection if you got it. However, the fact that people have some natural ability to fight it off explains why not everyone dies from it (every virus would kill you if you had no immune response, that's why HIV is deadly), but it's of little consolation to the people who found out too late that their natural immunity wasn't enough.

If there was a test to see in advance who would fight off the coronavirus without realizing they had it, I guess that would be a way to save some money and inconvenience giving them shots, but since we don't know for sure in advance who will or won't have an easy case, that's why we have to get vaccinated.
All the best lies have a kernel of truth. This is not remotely unique to antivax.

> So the bankers kept all their profits and everyone else lost big.

I believe the government actually made a profit on the bailouts (the TARP program), probably because they bought while prices were low. Not that there isn’t a lot to criticize about how things went down.

I wouldn’t put too rose-colored-glasses on the pre-central bank era either, we still had financial panics and bank failures and the fact that the world is more globalized/interconnected now is probably true regardless of if we have a central bank or not.

> The real answer is to do away with the fractional reserve lending

I saw an interesting thought experiment related to this a while back.

Say country A is careful about making loans, and B is less careful. Country B takes out 300% more loans, and runs into a huge bad debt problem, and has to write down 20% of the total of all lending. Say people lose 20% of their bank accounts (maybe because the currency depreciates after a bailout).

Which country was more responsible? Country A right?

But if you look at the results, after the write down, country B has 240% as much stuff (housing, infrastructure, etc). And the people there also have 240% as much savings in the bank, since that’s mostly bank credit backed by debt.

The author made the argument that country A resembled Russia and county B resembled China.

Examples like this make me feel that the most responsible way to handle debt (at least at the public policy level) is not really very clear, since even doing things that seem responsible can have huge costs in the end.
This is one of those posts that really hits me as a "maybe we can do this, but should we do this?"

After getting a (non-DIY because as much as I like hobby electronics I have a tendency to scope creep my little projects straight into incompletion) about a year ago, my main learnings have been:

- Cooking is insanely bad for the air in your house, even with an outside-venting hood. Any sort of medium-high heat cooking will spike the PM2.5 to multiple times that of the haziest days here in NYC, and with the windows shut it will stay elevated for hours after.

- The 20" box fan + MERV furnace filter hack is super effective for cutting down on the PM. A few days this July the wildfire smoke from the west coast settled on NYC and we had 40-70 ug/m3 PM2.5 outside. The box fan filter took it down to around 5 in a matter of minutes. I didn't even bother taping the filter to the fan.

- My A/C system's ability to precisely hold the temperature within fractions of a degree of the thermostat setting is impressive.

- With two people working from home in an old, unventilated-but-kinda-drafty ~700 square foot apartment, the only thing that gets the CO2 levels into "drowsy" territory (my original point of curiosity when buying the sensor) is running the gas oven for a while.
Naming the company "Science" really grates my gears. It strikes me as an opportunistic grab of a huge swath of cognitive and linguistic commons. Sure it's clever but if this company's branding gets popular with the general public it will irreversibly change how young people think about actual science, and that really bothers me.

Nothing is sacred enough for some people I guess. Not science, not even the human mind.

Just because they were vaccinated as children "without a choice" and refuse a mRNA vaccine does not mean they did not get the flu vaccine, or HPV vaccine, or others later in life when it was their choice.

> Its a "reordering" of the sequence. That's it.

Technically a PRNG state sequence could also have distinct loops, returning a reordering of only a subset of the sequence for any given seed. For example, `return state += 2;` would return two separate sequences for odd or even seeds. We know that a PRNG with N bits of state must necessarily repeat after 2^N invocations, but it requires further proof that a given PRNG will not repeat at smaller intervals.

> For example: the sequence: {AES(0, key), AES(1, key), AES(2, key)... AES(2^128, key), AES(0, key)...} is a cryptographically secure random number generator. The sequence will loop after its 128 bits of state are exhausted.

In light of the above, is it possible to prove this (through some property of AES)?

(Also, we can't really prove that AES, or any other current algorithm, is cryptographically secure. Tomorrow, a new cryptanalysis technique could be revealed which breaks it.)
So let me summarize what this thread has been, it’s been a huge effort just to say, “no the comment is wrong because at the time they set it off they’d ruled out an ice nine situation because it was actually a couple years before exploding it that they considered the situation to be a serious enough concern when detonating the first nuclear bomb to actually run the calculations. The original comment was utterly wrong because it had the timeline goofed even although the main point about scientists considering an ice nine type scenario was accurate” (which was the main point, no the exact timing).

That’s this thread.

And my original statement has two reading because the “when” is ambiguous, and only one of those readings would be wrong if the first is assumed wrong for sake of argument.
It's a good introductory write up, but there are 3 things about it that frustrated me to no end.

> "As a human, I can do this very easily. 100101011010010110001101 There, I just did it.

No, you didn't. That number is most certainly not random, there are biases in it, you just don't know there are. Your mind is not random. This is why we use dice and not people to generate random bits.

> What do you mean by “kind of random number”? Aren’t all random numbers the same. Not really. There are two primary types of random number generators.

I growled audibly at this one. Random numbers should all be the same. In quality, not quantity, of course. There should be no discernible difference. There is one kind of random number, only different types of generators, with a PRNG if the seed is provably destroyed there should be absolutely no way to distinguish between a number generated by a PRNG and a TRNG.

> The computer hardware isn’t the only source of entropy. The user’s own mouse and keyboard movements can be used as well.

No. These movements are not random. Similar to my first gripe, your brain is not random. We used to use this approach to generate entropy and now we don't because this is understood, "random" user inputs should absolutely never be used to generate randomness in anything security related.

> Despite the benefits of CSPRNGs, as with everything else in the tech industry, security can never be guaranteed.

I'm glad you pointed this out. Everything in cryptography is based on unproven axioms, this is an important point that people should understand, it could be that P=NP, it could be that an algorithm exists to factor numbers to primes, we think not but really we don't know.
I think it’s one of those things modern parents are going to have to understand about their brave new world, and teach their modern children. Like look both ways before crossing the street, remember that everything you write on the Internet is permanent, so think before you write, or if you don’t want to do that then at least write it under a pseudonym.
My biggest issue with it is its complexity. It's impossible to tell what the fuck is happening behind things like Metamask, which makes me wonder if the whole thing isn't fake decentralization with hidden centralized services or authorities working behind the scenes. It also means that it's hard to create different implementations.

I've seen fake decentralization in other areas in the very dodgy cryptocurrency ecosystem. A lot of times it's "we'll decentralize this eventually when we figure out some issues" but that never happens. After the ICO or coin offering or whatever nothing else happens in the repository and Tesla sells some more high-end cars.

The web was simple and its core still mostly is. It has a ton of extensions and newer protocols but you don't need all that to use it for its original document store purpose.
At least some years ago Oracle required to pay per underlying core - you don't need to know how many you are using at any point of time, you pay for all cores that can be used.
I doubted the article based on the headline. My initial memories of pokemon mainly involve grinding away by myself on my old Gameboy.
