This stack overflow question has some nice pictures of the LoRa "chirps". They use rising/falling frequency modulation to allow operation at startlingly low signal to noise ratios.

(Also, the hardware they're using is fairly generic, and pretty much all the vendors selling them offer them in 915/920MHz and also 868MHz and 433MHz variants. I've seen claims of over 10km range with 433MHz LoRa gear without special antennas or clear line-of-sight...)
Ok, so a population that is majority not at-risk and extraordinarily self-contained is going to be instead distributed into the wider population en masse? Seems insane.
This one easy trick will save you $150! Just stay up an hour after bedtime ;)

I got in the habit of doing this kind of calculation early in my career before realising it is a) pointless unless someone will actually pay you that money if you instead do work, and b) still not a healthy way to think anyway in many cases where a) is true, due to life's necessities.

It might be "cheaper" to pay a kid to mow the lawn but sometimes I find it relaxing.

Solutions of hundreds of dollars? For what exactly?

Reminds me of the movie Hackers where they used buzzers. And why not? The only thing you gotta do is use pre-planned keywords/acronyms.

I went to several (music) festivals, big ones between 2002 till 2004 with a few smaller gigs later until 2009 or so. Back then we just used SMS or phone call. I didn't even always have a plan during the mentioned years. Especially outside the country (and NL is small) it was always a surprise to get the next phone bill (one time I paid something like 30 EUR per megabyte, in Serbia). Within the EU, these work with your normal plan nowadays.

I don't know how it is nowadays, but back then on large festivals providers would put up extra (mobile) GSM antennas at the location. I assume they still do that. I can imagine there's a lot of smartphones up in the air to record the magical moment (and ruin it for the people behind you). That alone is a reason why I wouldn't wanna go.

A dumbphone seems still clever if you go outside the country. A rugged one goes for say 30-50 EUR or so. It won't contain or give access to your whole life if it gets confiscated, no social media means you can focus on your stay, and you can still contact authorities or friends if required. Just make sure you add the personal information of those you need to contact (should be on your SIM, though possibly that's too much info as well). Oh, and the screen won't break or get damaged (if it does /care), and who cares if your dumbphone gets stolen. I suppose people generally take the risk, but I got burned once (got a digital camera as birthday present worth ~300 EUR in 2004 and it got stolen after I had it for less than a week). You can always give it away or sell it afterwards (like a real burner) or reuse it for the next journey.

Now, back when I went to music festivals, you'd sortof stay together cause you could find each other but it was a bit annoying. If you could automate it, like you can give your position with WhatsApp, then that'd be great. However, with WhatsApp you decide who can access your location, while with this solution its available to all. That might not be what you want.

Other sports like hiking, skiing I can imagine to use this technology. Even people who live "In The Wild" could meet up with other total strangers, if that's your thing. I mean imagine using this in some huge forest in Canada, or on Greenland where you suddenly notice another life form.
Yeah, I'm not entirely sure this is interesting. The media seems overly concerned with 'COVID-19' specifically and I'm sure the backers of this project like to see relevant keywords, but I think in terms of an outbreak it would be more useful to consider specifically how this has immediately contributed to deviance from normal.

"... we've found 19 cases of covid-19 in [insert place]", or "35 deaths from coronavirus" deprived of context has nearly no utility.

All those gripes are optional features.

Your parser or encoder does not need to support indefinite arrays, that feature is clearly designed to be used with some practical limitations like “I don’t know how many but let’s assume less than x, and I’ll send a STOP when I’m done”. Canonical ordering is optional. Yes, a typed system that has more types, IDK what to say about that other than you don’t have to use them. And yes, tags need to be supported on both ends, just like ANY DATA that is being transferred, compare to a strict schema’ed system and I no difference except that you’re only partially required to adhere to the plan.

Maybe msgpack is just objectively better because it has less features. IDK. Doesn’t matter because CBOR got an RFC and is actually popping up in places. If there was a competition, cbor won, right or wrong.
Your pools may have incompatible features in use that would prevent this. I recently set up an Ubuntu (19.10 desktop) box and cannot recv it's datasets on FreeNAS.

For now I'm just doing rsync of the snapshot directories, not upgrading the Ubuntu pool, and waiting on FreeNAS feature support to match.

You're right about that. Children are practically immune. As I understand this has to do with innate vs acquired immunity. Children are born with very strong innate immunity and as we age innate immunity decreases while acquired immunity increases, untill old age where both decline.

Many (most?) applications do not actually care whether a byte blob of text is structurally valid UTF-8. They are either passing it around as an opaque byte blob, or already applying much stricter application-specific validation. Validating UTF-8 automatically at the serialization layer is a huge waste of cycles, especially in a big distributed system.

Why not? Who gets to determine what counts as being part of the movement? I thought that, broadly speaking, the movement was about the method of producing and licensing software. If a certain group produces F/OSS software, but is internally abhorrent, they're still part of the F/OSS movement.
I wonder if "Audio Sharing" [0] works with Voice Memos so that you can record the mic input from two people wearing their own AirPods.

If not (and the grossness of sticking someone else's earbuds in your ears aside), I wonder if both people could wear an AirPod from a pair.

If Voice Memos does implement sharing, then you could potentially have 4 mics and start a walking podcast with guest appearances and all.

That's right. It's not beyond the point because in both countries, these millions of casual retail and hospitality workers are the source of the risk discussed in the article (they won't self-quarantine because it would cost them their income). It would be wrong to look at the chart you linked, which shows Australia and Western Europe as green and the USA as orange, and conclude that the USA is unique among developed economies in having a casualised workforce and "zero universal guaranteed paid sick leave."

and what are the second-order and third-order consequences of abolishing gender roles? do we think every civlization set them up because they were all simultaneously bumbling and monstrous? was it a conicidence that they all succeeded, while others didn't, and in fact any civilization that gave women more freedom quickly fell into chaos? Rome, near the fall, was said to have been 'ruled by women', and as the Arab Empire began to allow women to be teachers and preachers and clerks, they quickly descended into disorder. Just a coincidence, I'm sure. It was just a conspiracy, on a grand scale, no doubt. Patriarchy is oppression, after all, like the hierarchy mentioned in the article.

> I don't know what the right solution is.

This is a bit of a wild theory, which I definitely can't prove, but I am tempted to blame part of it on "zero tolerance" schools.

Schools are meant to teach the material, but they're also meant to give students practice at working within a social framework. Being on time, speaking in turn, keeping track of assignments, relating to peers, etc.

People have a lot of opinions on that, but the point is, it's reality. Kids are definitely picking up from schools an idea of what is normal when it comes to how social groups work.

Before zero tolerance, when someone did something wrong, the normal way to handle it was to try to understand both sides, then exercise the discretion given to people in a position of authority, then make a judgment call that seemed fair, reasonable, and proportionate. But now the normal way to handle situations is to more or less unconditionally penalize the offender without any leeway being given.

So now we have a whole generation or so of people who grew up having that style of authority modeled for them. When it comes time for them to exercise authority, what are they going to do but what they learned by example?

If this wild theory is right, then a (long-term) answer is for schools to stop teaching our kids that this is how society should work.

I'm personally in the same boat (and use a philosophically similar JS-based framework called SailsJS instead, right now)

For me: I need services that support the UI, as well as a public-facing API with basically the same data. I don't have the time/resources to build/maintain them separately, and my perception is that GraphQL and the wider ecosystem around it haven't yet reached the same level of ubiquity/maturity as plain-old REST.

A single, well-designed REST API that can be consumed by my own UI as well as public clients is how I'd prefer to handle it right now.

There's plenty of reasons to use Redux, even with the additional variety of (good!) options in the ecosystem.

Leaving aside (and I know this hard) the controversy of Tesla's valuation, Elon Musk and the environmental virtues of electric cars, think what a historic success Tesla is as a car company. There have been dozen(s) of car companies started in the US since WW2 and you could argue that not one of them has been a success. The biggest Kaiser Motors, has probably been surpassed.

For decades American and Japanese manufacturers have tried to compete with European luxury brands. American companies had almost no success and Japanese very little. Lexus does well, but it never displaced German car sales the way Tesla is now. I am not a Tesla fanboy, but I do like cars. You have to respect the product.

"The last addition is the ability to do raw, encrypted sends and receives. The idea here is to send raw encrypted and compressed data and receive it exactly as is on a backup system. This means that the dataset on the receiving system is protected using the same
user key that is in use on the sending side. By doing so, datasets can be efficiently backed up to an untrusted system without fear of data being compromised."

Unfortunately it's taking a long time for the feature to propagate through the ZFS implementations. I don't know if rsync.net's servers support it.
I think the idea was that once students are done with their finals they're going to want to celebrate and relax by throwing parties or drinking and it's best that they don't do that in the dorms and keep people up all night.

Because it is a bad thing regardless who does it. If the supposed good guys were actually as good as they thought they were, they would simply aim to do whatever jobs need doing with as much integrity as they posess. They wouldn't be grabbing power, for any reason. There is no "enlightened" reason to grab power. If you don't like how someone else runs something, it's not your only option to try to take it over from them. You can also simply not join that club and not care what it does or how it does it. An organization like OSI isn't like a geographical country where you are forced to be in it, and so there is some legitimate excuse for actively vying for control over it and it's policies.

Authoritarianism in schools is very old; it definitely didn't begin with what are now called "zero tolerance" policies. I'm pretty sure we would have noticed if attending an authoritarian school gave you an authoritarian personality style, especially given the interest in the latter in post-WW2 psych studies.
seL4 Design Principles
> He said a lot of things... often contradictory.

Agreed, but massive tax cuts for corporations and the wealthy are something he campaigned on and delivered on, like it or not (I surely didn't like it).

> And his growth rate hasn't been particularly different than Obama's despite the super stimulus of deficit spending during a non-recession.

On main street and the overall economy, sure, the growth rate hasn't been much better, and wealth and income inequality haven't reduced [1], although they didn't reduce under Obama either.

On Wall St however, growth has been blockbuster since his election (S&P up more than 30%) with investors reaping the rewards of stock buybacks and lower overall taxes. A good deal of this rise was right after his election, on the expectation of the tax cuts that eventually passed. The stock market is what crashed. Main street might follow, we'll see.

> Maybe it was the trade war or maybe there's just a limit to giving corporations huge tax cuts when they're already awash in abundant profits and capital.

I think we're in agreement here. The massive tax cuts to corps and wealthy people are what juiced the market and set expectations sky high. The trade war probably didn't help either.
