There is no good metric for comparing test rates as well, tests per million makes no sense when a lot of states within the country have almost zero cases. India's less than 5% positive ratio on tests even in hotspot regions do not indicate a massive lack of testing.

It's not a matter of dying vs not dying. It's a matter of people dying from covid or dying from stress related disease like heart attacks, suicide, etc with economic collapse. It's impossible to know before hand the exact prescriptive policies to minimize death over-all. Make no mistake, leadership is going by their gut on this. There are models, but the models are not precisely predictive, they are directionally persuasive.
It appear that sending encrypted content is a bet on whether the user pays for the content or not. I'd wager that for most page loads people won't go on to pay. So if page-loads become larger on average due to the encrypted content then the real benefit here is that the original content providers will be hit less (since amp can fetch the content all at once), but perhaps more importantly, google can index this content.

edit: So in total, users' bandwidth won't be saved - google is just serving itself, but packaging it as a user benefit.
This seems like easily the biggest win available to most homes, at least in the UK.

Modern building regulations mean that new homes have to be so well-insulated that heating requirements are small. We have a lot of old housing that was not built to those regulations; some of that has been refitted with insulation, and the rest should be.

Whereas the heat that goes into hot water just goes down the drain, even in the most modern homes!
That's not true anymore.

Some time ago Amazon made changes to the way they sell Apple hardware. It is my understanding that Apple gave its blessing to let Amazon sell their products directly with the requirement that third party sellers aren't allowed to do so anymore. In my opinion that's a welcome change.

> Your “we” is likely unrepresentative even now. Reading or telling stories to children every night is not a universal pastime.

I meant we as a society. Not everyone does it, but it is general recommendation. It was not even recommendation back then. The point is, we as society are collectively doing it a lot more. We as a society also push parents to do it a lot more. In 19 century, you would not had people claiming that someone must read to babies every night - although you do see people and even educators pushing this one.

> Children got less attention because there were more of them and people were busy but they weren’t feral

The origin of kindergarten are German cities with poor kids in city running around whole day. Middle class kids lives were highly controlled, including a lot of control over their entertainment, hobbies and so on. But poor families could not afford any of that.

In rural villages, even my grandmother remembered being responsible for gooses along other kids while adults worked fields (they were comparatively rich family with rather larger farm). It was the normal way of raising kids even in 20 century.

> People want entertainment apart from gossip. That means music, song or story telling

Yes, but these are songs and story telling for adults. The kids can listen, but the original claim is that these stories were aimed at adult audience. Which is true. The fun things for children and for adults are much different. And the original stories when I read them while ago tended to be much longer then what I read to small kids. As kids grow they start to have preference for older and 10 years old will like long version. But 4-5 years old less likely.
I love how people reimplement Plan 9 (poorly).
Links in each chapter's TOC don't work.
Imagine you're doing:

SELECT * FROM EMPLOYEE, DEPARTMENT WHERE EMPLOYEE.DEPARTMENTID = DEPARTMENT.ID

The naive thing would be to iterate employees and for each one read the corresponding department. However that would mean one disk seek per employee.

Disk seeks on the rotational disks relational dbs were developed for took hundreds of ms to complete. Even today's rotational disks have seeks that take dozens of ms. So doing one seek per join result doesn't work at all. You can add caching to disguise to some extent, but that costs memory.

Compare to B-Trees: You build an index on EMPLOYEE.DEPARTMENTID. That index is also a B-Tree. Because they are sorted, you can just walk both employee index and department table in parallel by id. You only need to do n/k seeks (where k is branching factor of the b-tree). You only need one record worth of caching per table (the one under the current cursor).

Bonus: because the indices are sorted, it's easy to pipeline each seek after the previous to further reduced the latency of the query.
What about BAT?
Copyright was first and foremost created to reinforce censorship, which tends to collapse when the means of (re-)producing "creative works" become cheaply available to the masses. It is older then liberalism: the right to copy a work was a right of the publishers given to them by the monarch, with the intent to limit who can publish what and under the threat of violence when disobeyed.

Transforming this "copy-right" from a right given by the monarch to a right given by the authors was a key event on the way of Liberalism replacing Monarchism and changing all common law to be based on human rights. One should notice that this "exclusive right to copy" restricts the right to use such "intellectual property", which is why Article 17 of the EU Copyright Directive must be opposed unless, at least, fair use is granted.

Early modern copyright was even more restrictive: its intent was to restructure what became an uncontrollable market: having authors license their works exclusively to some large publishers starved the small presses and ensured a controllable elite that would not dare to print seditious materials. Owning an unregistered printing press was illegal under the threat of violence. It is naive to belief the primary intent was to prevent harm to the income of the authors. Until today the right to copy is mostly a right of the publishers. Authors sign it away and consumers do not get it.
Maybe after seeing how relatively well they’ve come through this compared to my folks back home (I’m American), my neighbors will fight harder to keep the things that take some of the sharper edges off life in Germany.

You're taking this too far. Stop trying to do that.

There is an island on which there are hungry people and hungry dogs. There is a limited pool of donor funds.

The fact that there are people asking for money for the dogs before all the people on that little island have full bellies is just sad.

The dogs will feel no pain from being put to sleep.

Nobody can, will, or wants to even suggest that the children be put to sleep. We will let the children suffer horrible pain before we ever even consider suggesting such a thing.

So every dollar spent on the starving dogs is a dollar that could have prevented some pain for the humans there. It would cost no money and no pain to put the dogs to sleep and ease the pain of some children.

So stop trying to bring the rest of the world into this to win the argument. This is a localised problem on one island, and every dollar spent there should be spent on reducing harm.

SARS and MERS did not provide immunity against each other nor against SARS2.

There is no indication that other common coronavirus infections such as those that cause 10-30% of common cold cases world wide provide any immunity to the current virus.

Also given the sheer size of India it’s unlikely that there would be a pathogen that provides immunity on this scale that would not have been identified previously since it would end up causing complications and deaths in some infections even if at much lower rates than previous epidemics.

If it also managed to spread across India It would’ve also spread worldwide.

Lastly like someone else mentioned migrants native to the region where hit pretty hard everywhere else.

I've seen a design which exploits this by having the waste pipe flare out enormously - imagine two squat cones joined at their circular faces. You get loads of surface area for heat exchange, with slower flow across it, and no chance of blockage.

I think you have somewhat unrealistic expectations of what even a decent photographer could achieve with a graduated neutral density filter (not to mention tilt/shift lenses... maybe 0.1% of even professional photographers use those).
The photos in your blog post would have been really hard to achieve with "traditional" photography methods to cover the huge dynamic range (a graduated neutral density filter won't cut it for a street opening facing the sky). Most experienced photographers would employ some form of exposure stacking in that scenario, same as the iPhone did. Of course having more control over the blending would be great.
I think if you tried to take the same pictures with a traditional camera you would be surprised by how good the iPhone pictures are compared to the effort it takes to achieve a comparable result.

Oversharpening is a curse in the industry to be sure, unfortunately to most people an oversharpened image looks "better".

Not in my experience in Germany:

Ordered items on the 24th (a Friday) and they said normal delivery was expected on the 30th (next Thursday) and premium would show up on the 27th (next Monday). Didn’t want to pay for Prime, so went with the standard shipping. Received the items the next day on the 25th (Saturday).

I’m not complaining, but I’ll never trust the Prime/premium shipping again which now just feels like a scam.
Sweden has a strong healthcare system.

For the vast majority of other countries delaying deaths will mean saving many lives, because of overwhelmed healthcare systems.

There is no location tracking.
You look at the OpenTrace source code or the BlueTrace whitepaper, and see where this is taking place, and let me know.
The only way they could location track is if the app data was enriched/correlated with other data, which basically means they can do fuck-all location tracking with this. They only have timestamps, temporary identifiers, mobile device models, transmit power etc.

> I, like many people, need to exchange my time for a paycheck. During this time I often have to pay close attention to minute details in a text document, and think through implications of design proposals.

Anecdotally, I can concentrate and focus a LOT better when I get a plenty of sleep and exercise and don’t drink any coffee at all for at least a few days beforehand.

I do love the flavour of coffee though so I still drink it, but I try to keep my intake low.

> The result was: I was sleepy at inopportune times.

I’m certainly no expert and definitely don’t know your specific circumstances, but on the surface this looks like a sleep hygiene or even diet issue.

> One in the morning, another in the afternoon.

I don’t know what age you are but I used to do this in my twenties and never had any problems sleeping, but in my thirties a coffee in the afternoon really messed with my sleep, although it took a few visits to the doctor to realise. I now very rarely drink coffee after about 1300 and I sleep a lot better. Basically, if you’re young, you can get away with it but be careful. If you’re not young then... maybe your body handles it differently, lucky.
Yes. The whole idea of looking for a natural attenuated strain is we can use the natural spread of this strain to prove it is safe. This is explored in a lot more detail in the other recent posts on my blog.

Yes it is possible, but the only way we will know is if we look. I am arguing we should look.

> I stopped following iPhone models a while ago and have no idea about the differences between 11, XR, and XS.

As other commenters have mentioned, the cameras seem to be mostly the same across the available iPhones.

If you're looking for the absolute cheapest phone, the SE or XR would do.

The 11 would be good if you find yourself taking a lot of wide-angle shots. (For example, it's better for travel landscape.)

If you find that you zoom in often, the XS (mainly available from resellers or preowned) might be useful. Personally, I don't think it's that useful for day-to-day phototaking.

I mostly agree, but I think there was a bit of a difference in quality up until about 15 years ago.

This was due to the nature of the competition between news outlets. It you have only few suppliers in any domain, then a possibility of a "price war" is relatively small. It's much easier to predict how our counterparts will behave and dumping prices hurts all the participants. It forces the competition to move to different areas - like marketing and quality of service.

Once there were more competitors, due to the internet being a thing, all bets were off. No one could hold to their position just because he was considered more reliable by a marginal degree.
I don't think that was ever the argument. Increased testing has been recommended by the WHO, has noticeably helped prevent a bigger outbreak impact in South Korea & Germany and quick isolation makes a lot of sense for a disease that is asymptomatic in most patients.

It's more subtle than this: bokeh blur can look very different depending on lens design and configuration. It can look like toruses (tori?), various sided polygons, stars, double overlayed low-pass circles with resonance at the edges, ovals shaped and rotated into a full-picture swirly effect, and so on and so forth.

Depth of field blur is a very organic effect and in many cases part of the signature look of lens designs. It is not just one, parameterless filter one can apply to an image.

Given the chances of a vaccine being found within the next month or so are slim to none?

Ansible connects to remote servers to configure them, while Terraform calls cloud provider API’s to provision resources.

For example, you can use Terraform to provision virtual machines, database instances, or Kubernetes clusters on AWS. Terraform does this via the AWS API.

In my opinion, Terraform is better for provisioning because of the way it manages its own state. Terraform remembers what resources it created the last time it ran, and can edit or delete them according to any change in your Terraform code.

I like Ansible, but not for managing cloud resources. Ansible has no memory. For example, if I ran a playbook that installs MySQL, Ansible has no built-in way to undo this change and bring me back to my previous state.

This is one of the reasons that heat pumps don't play well with high-density living.

A friend who had a semi-detached house looked into getting air source heat pumps. That would have involved a big fan unit sitting just outside his kitchen window. He couldn't get planning permission, because it would also have been sitting just outside his neighbours' kitchen windows, and it's rather loud.

Ground source heat pumps don't have that problem. But i live in a second-floor flat (third-floor apartment for the Americans) - where am i going to find a ground source? If i run a pipe down from my kitchen, i hit my neighbour's bathroom!

There are several comments on this page suggesting using an outdoor pool has a heat source. Different worlds!

SICP is about deeply understanding computation.

Scheme is a good language for SICP because it's simple. You can build a Scheme interpreter as a class project. You can analyze it formally. Etc.

Python is a good language because it's readable and writeable. But it doesn't work for SICP since it's too complex for that. Python also intentionally omits things critical to SICP (like tail recursion).

Calling this book "SICP in Python" would be like taking your favorite poem, releasing it into a different language, and finding that the translators wrote a completely different book, with a different theme, to make it rhyme and the rhythm hold. Just something different with the same name.
