Having the last index and the length be the same may not be the good thing. for instance, if you translate python's negative indices (x[-i] = x[len(x)-i]) directly the last element would be...x[-0]? But then having the last element be x[-1] in python is also not entirely obvious.

As usual, Cloudflare wants to pretend that they are community players, but they aren't. If they weren't hypocrites, then they'd submit their patches like [0] for upstream review, but they haven't. (I searched LKML.) I understand the underlying desire, which is to avoid using a queue for CPU-bound work that could be done immediately, but there doesn't appear to have been any serious effort to coordinate with other Linux contributors to figure out a solution to the problem.

R0 is what it is, but I agree, it seems like there should be a more meaningful measure that takes factors like incubation period into account.
It very much depends on the market.

In the general case, almost all websites and web apps don't need offline storage at all.

But the ones that do often need it for very business-enterprise reasons, and here Apple is taking a bit of a risk. I've watched companies hang onto old versions of Flash well past the sell-by date because for quite some time, it was the most practical platform to build a cross-platform videoconferencing client in. And once it's built, the opportunity cost to throw it away and switch to [OTHER_TECHNOLOGY_X] matters.

Employees at nine Amazon warehouses have contracted the coronavirus
Once you take your head out of that iAss, you may see how defensive and idiotic your comment is.
In my opinion, the quarantine just worked.

Here's my thinking. We know the following (maybe my information is not entirely correct, but the reasoning is still valid):
1) a host is infectious for about 14d;
2) the virus survives on surfaces/objects for 9d (this is based on other coronaviruses, but a more recent study suggests it's shorter).

If you want to stop the spread, or reduce it significantly, you need to quarantine people for at least 2 x 14d + 9d.

Why is that? Because, the first infected in each household will stay so for the 14d, and assuming all the other members of the household are infected by the first person, and assuming the infection happens towards the end of the first 14d, for safety, you need another 14d. Plus, you want to make sure the virus is not still active via surfaces/objects, so plus up to 9d.

If you go further and assume that not everyone is infected by the first person to have the virus in the household - so you will have multiple generations of infections - then you need to add maybe another 14d. And so on.

China did some 2 months of quarantine. Chances are very high they actually succeeded in reducing significantly the number of active cases. No need to appeal to conspiracy theories at this point.

Why do we see a resurgence of cases? Because the 14d is just the avg. Some people reportedly can be sick for longer, many can be sick without having serious symptoms, some people don't respect fully the quarantine etc. Because of this, stopping it permanently is going to be very difficult via quarantine alone.
... or find it really necessary. Banks, for example, have the clout to expect this kind of behavior. The built-up reputation and long-term partnerships a company and a bank build up can out-value all kinds of IT inconveniences.

Perhaps the author doesn't realize that WebKit is open source. They could have used their screed to propose to the WebKit team that a first-party page loaded from a file:/// URI not have its client-side storage subject to the 7-day purge, by setting the "firstPartyWebsiteDataRemovalMode" network connection property to "none" — patch included! But they did not, which is quite disappointing.

I've often thought about a similar idea.

I'm still relatively new to the industry (3 years programming, 1.5 professionally), but I've found that I'm a BIG fan of refactoring. To me, it's like writing or communicating ideas in general, which I really enjoy. I love taking a complicated idea and trying to explain it in the most simple and readable of terms. It also pushes me to really understand the intent behind the code/text.

To that extent, I enjoy editing and revision much more than creation. So, taking a role as a 'refactorer' actually sounds great!

A lot depends on whether you mean:

* R0 when the disease appears first time and people dont know about it

* R0 when people learned about disease and changed behavior.

Assuming disease is new, one person sick with SARS will infect more people then one person sick with COVID.

Due to stronger symptoms and shorter time to symptoms, we learn SARS is issue, change our behavior and quickly close small area. SARS will spread less. In covid, by the time we figure area is infected, a lot of people are infected elsewhere. It takes us more time to react.
The comments posted so far seem to miss both the ambition and innovation of the Internet Archive's efforts in recent years and the boldness of their new initiative. They developed a way to make in-copyright books available for free to anyone who wants to read them online: by keeping a physical copy of each book they scan, they can justify "lending" it to one person at a time online for a limited period. Their collection of scanned in-copyright books has been growing rapidly. Try searching at the Open Library for some popular book you enjoyed reading when you were younger—mystery, Western, young adult, science fiction—and they're likely to have a copy that you can "check out" and read in your browser. You even get to enjoy the yellowing of old paperback pages without the stench of the decaying paper.

The new initiative is bold both because it meets an urgent, unprecedented need—providing books to millions of people who are locked down and cannot go to libraries—and because it seems to be taking significant legal risks for the greater good. The announcement at archive.org links to a document [1] that in turn links to some attempts at legal justifications for the move. I'll let others weigh the merits of those arguments. I suspect, though, that if major publishers and other deep-pocketed copyright holders tried to contest it the Archive would have a difficult case on its hands.

Preserving Optionality: Preparing for the Unknown
Very nice, I think we can certainly use more knowledge sharing around these topics!

I definitely hear that many of my more extroverted colleagues are taking the isolation and lack of social interaction quite hard. As a more introverted person (who has done long stints of working remotely in the past), I find coping with this part less problematic. Instead, the "co-homenaut" problem is harder to deal with, as I have two young children. (In this sense, I wonder if "co-isolation" would not be a more appropriate phrase, as "isolation" doesn't quite capture it!) Are there sections of the site more focused on this aspect, or could it be made more prominent?

Mapping global coronavirus cases over time
I'll try to clarify. The article argues that the death toll from covid-19 is low enough that it doesn't justify shutting down the economy. However, we've seen that hospitals will be overrun with covid-19 cases for a while even with a lockdown, so this would likely be worse without a lockdown. My point is then that, triage or not, there will effectively be no hospital service for a certain period. So you basically have to add the death toll of having no hospitals for a certain period. Avoiding this additional death toll requires refusing corona patients, not just triage.

Perhaps the article was arguing that even with covid-19 deaths plus "health care paralysis" deaths, it's still not worth shutting down the economy. In that case my point is moot.

People are very determined and cooperative. My parents are in China, basically after 2,3 days since it began it’s all over the news and people got serious about it. My hometown, which is a small city in southern China, people are very cooperative and literally do not go outside as soon as the news broke out. I was also chatting with my parents daily as well to ensure they were at home. I wouldn’t trust the numbers completely as well but I think at least the curve makes sense.
Nobel Prize winner predicts US will get through crisis sooner than expected
Someone I know was driving down a country road and struck a person in the middle of the road and killed them. The person wasn't drunk as far as I know, but their car broke down and they were trying to walk to somewhere. Why they chose to walk in the middle of the road at night no one knows, but due to the desolate region and the unexpectedness of it, they were not seen. There was no jail time and charges filled. It was understood that the pedestrian shouldn't have done that. It really messed the driver up, they're a very nice person and having caused the death of someone really hurt them, even though there really wasn't anything they could have done.

Obviously every instance is circumstantial, and I didn't really read anything about the case, but if drunk people were lying down in the road, at night, in dark clothing, I don't see a crime.
Your peers were being rational, but it's a drop in the bucket. I've come to the conclusion that privacy can only be protected with legislation. There is too much surface area to protect for the average person to police their own data trail online. Even experts have a tough time doing it. You'd have to abstain from virtually everything, and even then you can't keep other people from posting you, tagging you, etc.

This isn't a technical issue. It's a political issue.

From the PoV of the person who responded they didn't provide any relevant information that would indicate what platform they run, or what speed they expect, or why they think 800MiB/s seems slow to them. On many platforms this would be a pretty good result. At first look, it looks like they expected the speed of unencrypted storage, because that's what they tried to compare against.

So the response seems reasonable at first glance to me. They got the answer to their main question. (which they omitted from their blog article)
It's true that a lot of PHP/Python/Go programmers look to Rust rather than C++ when getting into performance-oriented code. But it's not really a stepping stone, because you never have to leave.

It's true that not a lot of people are using Rust for embedded software. That's a much harder nut to crack because so many of the toolchains are proprietary (and embedded support in Rust is still missing quite a few things).

It reminds me a little of the time when Berger and Senna were teammates. Two very good drivers but there was no dispute who was the number one and two driver. It’s much easier to keep peace in a team where the hierarchy is clear. It would be interesting if Mercedes hired Verstappen next to Hamilton. I doubt they could keep the peace then.

selfish reasons to stay inside:

1. Even if your not at risk, your odd's aren't 0.

2. You may care about somebody that is at risk. One family lost four people to the virus.

3. If the hospitals surge you could have an accident or need medical care and they won't be able to help you.

4. Dead people don't buy stuff.

5. What if you or someone you care about is one of the 2-8% that needs a oxygen and/or ventilator and their aren't any because we surged the hospitals.
Apple disallows third-party web rendering engines. Google Chrome on iOS uses own networking stack.

Before You Use Kustomize
You're probably selling yourself short. Differential equations isn't a bad course if you did well in Calculus and have the patience to grind out a ton of examples. E&M, StatMech and/or Lagrangian Mechanics also ain't bad if it's taught well, but this is a case where you really have to do the diff eqs before you can do the physics piece. Diff Eqs is the language of most of physics; trying to wrap your brain around the other parts and differential equations at the same time is too big a lift even for a galaxy brain. It's like being asked to compile kernel modules without knowing how to use a mouse or keyboard.

I've thought about trying to write something like Lenny Susskind's "theoretical minimum" book, assuming you have the prerequisites of differential equations and linear algebra. I mean, everyone struggles with the complicated problems, but more people should be able to appreciate the results. Meanwhile Susskind's book is pretty good!
Coefficient | Sr. Backend Engineer | Remote From India/North America | Remote Only | coefficient.io

Who we are
Coefficient is a VC-backed SaaS startup in the SF Bay Area. We are still in stealth and just raised a large seed round. The founders are serial entrepreneurs whose last startup, Shopular, was backed by Y Combinator and Sequoia and acquired by Rakuten Ebates.

What we do
Coefficient is a self-service data warehouse for business teams. Today's data tools and BI stacks were designed for data specialists and data engineers. However, as more companies and business functions embrace data-driven cultures, they are held back by the inherit complexity of existing data analytics tools, as well as the technical expertise required to set up, maintain, and operate full BI stacks. Coefficient's mission is to unlock organizations' latent data productivity, by enabling users to model, re-shape, and build reports using data from any data source—all within an intuitive, no-code interface.

Who you are
We are looking for a lead backend engineer to help us shape and deliver our vision. You will work alongside the founders to define product, design core backend architecture, and develop resilient, scalable systems from the ground up. You have 7+ years of experience designing and building complex backend systems
You have extensive Python experience. More details: https://angel.co/company/coefficient-io/jobs

This might technically work, but is an absurdly user-unfriendly.

Name a modern game that required you to manually manage game state files, let alone didn’t have autosave. It’s a feature users expect, and they’re going to have a bad time. I don’t want to play a quick game on my phone and have to remember to save and where I am keeping my save files.

I’d argue a far better options would be just to treat local storage as a permission like camera or microphones.
If the cookie is set by http headers, yes. If it's set with client side js, though, it's capped at 7 days (since ITP 2.1).

>By acting in this capacity the government can allow the market price seeking mechanisms of capitalism to operate on an appropriately longer time horizon.

This makes it sound like the Market is primary to the State, where observation/history very much paints things as being the other way around.

being able to purge old disks confidently in a secure manner is a upside huge enough to make this statement true in my opinion. There have been numerous incidents even involving companies specializing in securely purging disks. If your data is encrypted there is basically nothing to do you could even outright sell those from your DC or something. Just delete the keys/headers from the disk and you are safe.

Its also not possible to get data injected offline into your filesystem without having the keys. Without encryption you could just get the disk of the targeted server running somewhere and set your implants or what you have. When the server sees the disk back up it looks just like a hiccup or something.
Apple does not use that Webkit branch, however. They maintain their own branch internally that cherry picks from upstream. Webkit could very well accept a patch, and then Safari never ships that patch because they disagreed with it for use in Safari.

Also, unrelated fun fact: Did you know Webkit still uses svn? That Github repo you linked to is a clone of Webkit's own git repo (git.webkit.org), which is a mirror of their actual repo (svn.webkit.org).
