Other than needing to find a provider who does "water exchange" colonoscopies (in addition to the old standard "air insufflation" and the slightly newer "water immersion"), there's no downsides. Water exchange is more effective and less likely to cause pain.

Although most practitioners will do sedation-less colonoscopies with any of those techniques, water exchange makes it much easier.

> Why isn’t a water exchange colonoscopy standard?

> It represents a change in philosophy. Care providers have used air for a long time, and some doctors believe a water exchange procedure is too time consuming. There’s also a skill-set barrier. Many physicians are not trained to perform water exchange colonoscopies. Doctors also have to be comfortable with their patients watching them work. Because the procedure uses minimal to no sedation, patients can follow along on the screen, giving them full transparency.

While you need to be rich to be able to mine Bitcoin, you also have to dump those mined coins on the exchanges to cover your running costs (electricity, hardware, server operators, etc).
That's a very dubious way of looking at it.

Blockchains all have a bottleneck. All transactions in the world have to go through the miner. And the situation is actually worse than that because we don't know who will solve the useless Proof of Work hashcash function ahead of time, so EVERY potential transaction is gossipped to EVERY potential miner, and then the miners ALL go to town wasting electricity. How great!

Anyway, because of this architecture (preventing double-spending by literally aggregating all ambiguities into N potential histories of EVERYTHING, and then having them duke it out with PoW or PoS or any other way), we literally have a cap on how many "TPS" (Transactions Per Second) can go through.

Before Bitcoin, no one ever asked how many transactions per second an Internet protocol could support. It would be ridiculous to ask that of HTTP, or FTP or SMTP because there is no central bottleneck: the number of websites, files and emails that can be sent increases with the number of computers on the network.

With Bitcoin, Ethereum and other blockchain-based networks, this is not the case. The max number of transactions that fit inside a block is the most throughput you're going to get. The best thing to come out of these blockchains is Microsoft's Sidetree protocol championed by @csuwildcat but that's for identities, not currencies. So basically, you have a payment system which is super-secure and also super-wasteful.

It's as if BitTorrent required every computer to seed every movie, and BitTorrent maximalists called everything else that used a Kademlia DHT a ShitTorrent.

Except here, it's actually worse because you're not doing Proof of SpaceTime (like FileCoin) but you're requiring a growing number of computers to participate in a lottery proving they burn electricity and get rewarded sometimes. And this amount of computers is growing, just so we can do one operation (transfer money) 10 times a second. At least Ethereum made it into virtual machine capable of executingmore than one operation, thus enabling Turing-complete programming languages like Solidity, and smart contracts. Still, the way it's designed as a "world computer" it's basically a glorified mainframe, and gas is basically paying for time on the mainframe. It is the reason "flash loans" are even possible, they are artifacts of the idea that literally ONE transaction in the entire world can happen at any given time. Nice for atomicity guarantees, I guess, but overall not so great for almost every real world application.

Blockchains with global consensus about every transaction in the world are NOT what I would think of when I think "decentralized" in the sense of having no central bottlenecks. Actually @vbuterin wrote a great article years ago about the different senses of the word "decentralized".

You seem to have misunderstood my point. If you are offered a vaccine, take it immediately.

The point was that 100% of the USA could be vaccinated today, and the USA will not be done with covid.
Docker on Linux runs in a VM? No.

Systemd docker-replacement on a non-systemd Linux would need to run in a VM, though.

Systemd-docker-replacement: works only on systemd-Linux. Tooling for any other arrangement, including non-systemd linux, left as an exercise to the user.

Docker: works on Linux—systemd or otherwise. Has tooling to making working on macOS or Windows non-terrible and lets you use (mostly) the same commands as you would on Linux.

I'm saying that cross-platform tooling is what makes Docker Docker. Systemd can't replace it without replacing the tooling, even if it can do the same thing only on systemd-Linux.
It started in China, a country with 1.4 billion people and 20 million pop cities and even if you 100x their official number they did better than the US or Europe. There's few excuses for our mismanagement.
It matters because a million people dying is worse than ten people dying, even if those ten people were 50% of some population and the million were only 10% of another population.
If the US had in reality on the order of 100 cases, there could be a credible effort to get rid of all of them and reopen. You wouldn't have to lock down hardcore for as long. In Australia from what I've seen fly across Twitter, they had the luxury of periodically locking down a city when they saw a single case, to make sure it didn't escape into the population.

I agree that there could be a way for this to work in the US but it would be a long slog. South Korea seems like they could pull it off. So I'll grant you them for sure as being superior.
Men and women don’t have to be exactly the same for them to have equal rights. Maybe certain people aren’t smart enough to separate those two concepts, but that doesn’t mean we should be at their mercy regarding what we can publicly admit is true. We don’t have to dumb ourselves down like this.
I might be wrong, but I think it's used for both. *EDIT:* I've looked around and I must've been misremembering - the term "passive" is only used in the official docs when talking about passive location updates (there called the passive "provider", since to the app, it looks like one). The non-GPS category of providers (wifi, bt, cell) is just called "network".

~~Passive location requests are, as you say, when an app wants location updates, but doesn't care when and how often - when one makes an active request, all the passive listeners get called.

Passive location sources are methods of getting your location with the data already available - so WiFi if it's on and cellular if the modem is on.~~
Yes, due to the 2nd layer solutions it's going to bring along. You have the same idea in Bitcoin called lightning network (with growing adoption: 1ml.com).
I'd rather recommend booting a liveCD. grml, knoppix, whatever floats your boat. An init=/bin/bash shell needs quite a bit of knowledge to get working (mount rw, get rid of selinux, mount the real rootfs), is possibly just busybox and generally a pain. Even more so if you need the net to copy something over.

It isn't impossible, and OK in a pinch, but why make it hard on yourself?
There was both a policy difference as well as a behavior difference when it came to schools.

Also, case numbers are a bad thing to measure. Death numbers are more reliable.

EDIT: also, it appears state policy exacerbated the nursing home problems in California:

Brazil has the one counterexample that it makes very good airplanes such as

https://en.wikipedia.org/wiki/Embraer_E-Jet_E2_family

I rode in one of these and it is like Buck Rodger's spaceship compared to the Boeing 737. It's got less range than the 737 (it can't fly from NYC to LA but Southwest could serve CONUS from Love Field in Texas with it) but the fuel efficiency is great.

More to the point, it feels huge on the inside even though it is smaller than the 737. It's something you have to experience to believe. The comfort is more like a widebody 767 because Brazil did what Japan did to cars.

It's all the more remarkable when you realize that Embraer is the #3 airplane manufacturer in the world and there is no #4 that widely exports planes.

Boeing could go the way American Steel US market power to make it very hard for you to fly the E195 and love it.

Brazil has also been innovative in developing biofuel technology that hasn't been successful elsewhere. When I visited Brazil I had the feeling I had visited "another civilization" more than I have any place else I've been to just from the feel of the infrastructure.
In this case they couldn't even know that they are being overcharged by using iOS. It's like food hiding its sugar content.

It becomes more complicated because Fortnite is not iOS , nor apple. In the end the decision will be made over anticompetitive tactics. Because mobile marketplaces are a closed oligopoly, they 'll establish customer rights.
For me "countries that did really well" is mainly places like Singapore and Taiwan and South Korea, which got the virus earlier than USA and Europe but took it seriously from the very start.

Weird. My best attempts at measuring it here put it at somewhere 0.07s on my server.

It's even better not to be concerned with this at all. Take a look at the --cursor option.
I have to make a lot of assumptions, but a couple hours doesn't seem unreasonable for the core function. Among the many assumptions are the hash function, what is actually being hashed, what processor interface is, desired performance, etc.
Would you be able to share any evidence to back up your suspicions?
That’s why we have the "ch" which they cannot sound properly. It always ends up sounding like "sh" or "ck"
I've seen a lot of these comments to this effect but I'm still not quite sure: what is the issue with dbus? Is there another replacement that meets all the use cases?
It doesn't account for Africa, but many of best-performing countries have been island countries (Australia, NZ, Taiwan, Iceland, etc.). Islands have some fairly obvious advantages in fighting a pandemic, and it shows in the statistics. I believe Hawaii has also done much better than other US states. I'm not sure whether that's what the comment was referring to though.
> In that sense, systemd doesn't solve anything for the same reason sysv-init doesn't. All those preconditions in systemd will still either time out or never finish.

No, they will run until the configured timeout and be restarted following your configured restart policy. Once that's happened, all dependent services will automatically be started.

> The point is, back then I just moved the apache startup script to back, added a wait-and-check loop in that script and had everything in one place and done.

Nothing prevents you from putting a wait loop in the Apache systemd unit, either — in fact, it'll be a lot easier because you can use an override rather than needing to modify a packaged file which will be clobbered by updates.

> Now I'm at more complexity, a shellscript, multiple files and still not ahead in functionality and reliability. Progress!

It's interesting because you keep describing what sounds like the SysV experience, which I haven't seen since switching to Upstart/systemd over a decade ago.
So much questionable framing too. Prohibition is never and wasn't ever a progressive position. It's not about freeing people, it's about controlling them "for their own good". It's an authoritarian stance and we're still living in a world where most people subscribe to this.
"The rich world suffered relatively badly, but most of the dying has been elsewhere."

Saying the subtitle.

Elsewhere, meaning relatively poor countries. But even within the rich world the poor within those are disproportionately affected by Covid (deaths). But those ppl - at least in the USA - have worse health outcomes in general already.

Covid is both a disease and a symptom. Unfortunately, the disease lens is being used to distract from how it's a symptom of deeper longer running societal problems.

Why? Sincere question. Is there science to back it up or is it just fear of making a wrong decision?
Usually (using differential dataflow, for example) you have input relations (EDB) and you have some output relations (subset of IDB). You would loop over the output relation using your host-language to call some effectful functions using the result (printing, in the simplest case). Only deducing facts without calling an external function with those facts is not useful for an interactive application.

>>> Had to ditch the extensional database for that. Not strictly necessary, as it turns out.
> Is that explained in the paper?

Yeah, but only in short.

Usually you would provide a database as input. But if you have a strict call-convention (call to external functions), you can use their result to load your data dynamically from "within" you logic program, instead of the facts just "being there" or "appear".

This makes static analysis much easier and given a microcontroller is basically without storage, where would you load a database from anyways, that you wouldn't know beforehand?
I'd say "Florida secured their elderly population more quickly and carefully than in New York" misses the fact that New York ACTIVELY put its elderly in harms way by requiring nursing homes take patients.

If New York ONLY ignored the problem that'd be one thing... but they actively made decisions that led to a large number of deaths - and more importantly those decisions were AGAINST the CDC guidelines.
But it is a mess. You'll need 2 files for that unit (itself and the shellscript) plus changes to all necessary dependencies to put it in the right place. A sysv-init script is just edited in the right place and you are done.

Agreed. Also no way for apple to enforce refunds for purchases are even _possible_ if they aren't involved in the payment pipeline.
Except that he wouldn't because he knows that would manipulate the market and he's more responsible than that.
Just to skip over the pedantic wrangling over semantics here, can you tell me whether you think that Flamin' Hot Cheetos are a healthy snack? Because I think they're not and that's my main point.

How about China itself?
At this point, I am firmly of the opinion that we need a single, global standard for online payments that is just an electronic equivalent of cash or a direct bank transfer. Solid authentication of the parties. Explicit authorisation of each transaction or series of transactions to be performed. No other strings attached for anyone just because you're transferring money; that's what contracts are for. No arbitrary gatekeeping or labyrinthine terms for buyers and sellers, dictated by intermediaries in their own interests. No spying on who is paying for what and selling that data on to some shady broker for an extra cut. Ideally, the whole thing should be run as a public service in each country, at cost, with no intermediaries at all, in the same way countries operate their primary currencies as a public benefit that is beyond the control of any commercial entity. If not, then at least heavily regulated with a similar outcome. And make it illegal for any commercial entity offering goods or services for sale to require the use of some other payment method without also offering this one with at least the same prominence, so you can use something like an escrow service with a refund mechanism if you want to, but only if both parties genuinely agree to the terms.

With the increasing prevalence of online shopping, the increasing importance of reliable and efficient international money transfer to the global economy, and the seemingly never-ending ways the financial services industry can mess around both senders and receivers of money when all they wanted to do was send $X from A to B, we needed something like that long ago, but better late than never.
And they will continue to be bitten by problems specific to large-scope projects. Wanting something, no matter how much, does not let them escape engineering reality.
You don't offer any evidence for your claim except anecdotal experience of not knowing anyone who has died. Do you think it's possible that your local bubble of information (not knowing anyone who has died) is not actually representative of a true larger trend? I'm always curious about how people draw conclusions like this.
Bitcoin cash and SV are low on the carbon emission cause they forked from BTC right? So they re-used bitcoins early work. Or am I totally wrong here?

I think the intentions were good, but it's also probably true that public health officials have been reluctant to admit when there just wasn't much they could do about the situation that would make a major difference, save for employing totalitarian enforcement measures that no one wanted.

Masks in public are not all that burdensome, so imo the mandates were reasonable regardless of the actual impact, but I wish they would have re-evaluated closing businesses a lot sooner, since that did a ton of economic damage, and the benefit there seems very questionable. I doubt the CA statistics would have been any different if they had never banned outdoor dining, for instance, or even just kept most businesses running normally but with an indoor mask requirement.

Comparing CA to TX and FL, it's also pretty hard now to argue that closing playgrounds and schools made much difference either, and that has had a severely negative impact on kids. I understand doing it in the first place when everything was unknown, but they should have been quicker to revise in response to new information.
Ah, I expect that this is where things might go south! Since many apps are built for x86/x64, I'm sure that when you migrate to the M1 mac, they will run in intel "emulation" mode or just crash/fail!

I'm not talking about apps that you got from the app store or similar, but, rather, things you installed via homebrew!

When I temporarily had to move back from a more recent (~2014) mac to an older one (~2012), I got bitten by that becuse some apps installed via homebrew had been built from source with optimizations that the older machine didn't support. It was easy to fix, since I could just reinstall them as I saw them breaking, but it was an annoyance nonetheless.
> what people are doing behind closed doors with family and friends. Lockdowns don't have much effect on this.

At least here in the UK, lockdown meant not seeing friends or family (unless you lived with them). Was that not the case in the US? Of course if people flout the rules then they won't have any effect.
That is an even less fair comparison. The Chinese government has a tremendous amount of power over the daily life of its citizens in a way that isn't replicable most other places. There were stories of China literally welding doors to apartment buildings shut and forcibly dragging people away to quarantine facilities as soon as they tested positive.
Except these surrounding towns act as virus reservoirs for the large cities. That limits the effectiveness of restrictions. The “become COVID-19 carriers to own the libs” strategy kinda worked.
I think that's exactly why the COVID pandemic has been so bad. The outcomes aren't as terrifying as say, ebola. If COVID had been ebola but with incredibly high transmission rate, people would have shut down hard. Everyone. Everywhere. With an extreme abundance of caution. I bet we would have stopped that early.

Instead, you have this insidious disease that is so easy for people to compare to the flu and common cold, and it preys mostly on the oldest and most frail, so many people went with a "I'll be fine" attitude. And most of those folks did survive. And the virus just continued to spread, steadily doing its thing, killing millions of people worldwide.
Unfortunately it looks like this virus will be endemic indefinitely. It has spread to animal and human reservoirs we can't reach. Likely it'll end up being another one of those colds that children develop partial immunity against and most everybody catches another mutant of it a few times through their life.

We had the chance to eradicate it 16 months ago. But we weren't all ready. Now we'll have to live with it. And as it stands, if another one of those develops, we'll just blow it again. On a positive note: it looks like we got quick vaccination figured out.

With "we" I mean humanity.

One thing I do wonder is whether we will see permanent "Covid-free" zones such as Australia. Or whether they'll drop their guard after vaccinating.
Nursing homes had the biggest outbreaks. Perhaps only prolonged exposure in confined spaces between elderly people was the only pathway that mattered. In some ways I think of it like a fire spreading. There will be spots that burn easily and quickly. But once they burn out, the fire has nowhere else to go that burns as well.
What hardware profile runs your true nas? I've been looking to build something open source rather than using Synology.
The average age in many African countries is in the mid teens, and we know that age is one of the strongest risk gradients. So Africa is not at all comparable with the aging West. Australia and NZ have the huge advantage of no land borders. Everything and everyone comes through a few ports and airports, which already had the infrastructure established to tightly control and monitor everything. Meanwhile most European or North American countries can't close their sprawling land borders without starving their populations. (And the U.S. couldn't close its land borders even if it wanted to.)
> zero underlying (intrinsic) value

Cryptocurrencies, in general, do have value from their utility as a currency. They do sort-of-work in that regard. So perhaps as long as they're legal the value is somewhat above zero, as long as some are using it to settle transactions.

Can anything like the current prices, especially on thousands of competing currencies all serving the same effective role, be justified long-term? That's a rather different question. It's, at a minimum, an enormous speculative bubble, in my opinion. Ponzi might not be the wrong word for some of the wilder "store of value" claims.
Fixed mostly to relatively. That wasn't my main point really. I thought the data points were interesting.
