Turns out that e-ink displays typically don't mix colors this way. In order to get multiple colors in a single display, they use sort of colored-balls of various densities suspended in a fluid. Then, using the known viscosities of the fluid in the capsules, they can vary the charge of the electrodes very quickly to sort of _drag_ a color up to the top.

But when you do this, you're dragging a _single_ color.

_All_ the colors are in the capsule, but you can only truly pull a single one at a time, a true pigment-like mixing isn't possible. If you pull the Cyan up, you're necessarily losing the Magenta, for example.

If you had a high enough resolution addressable grid, you might be able to put the pixels close enough that you couldn't tell, but you'd still be basically doing sub-pixel color at that point, not truly mixing the various colors at the base level.

Maybe there are other e-ink displays doing something else, but all the ones I've seen are doing some form of this approach.

Here's a fascinating video on how these displays work, and how you can modify the firmware of the driver to get faster refresh rates (with an increased risk of burn-in). https://www.youtube.com/watch?v=MsbiO8EAsGw

I mean. You're putting in two words. What do you expect? If you walked up to a human randomly and said "black people," what do you think you'd get out? It wouldn't be this, but it wouldn't be a cogent rephrasing of Wikipedia either.
Correct, it is more a thought monopoly than one of numbers. Its a lifeline between everyone who has a megaphone. I'm not sure one platform that all journalists choose to prioritize falls under traditional antitrust concerns, based only on that fact, nor does that fact alone really strengthen other antitrust concerns.

> I'd love to switch to ZFS, but the RAM requirements are absurd. I don't have a separate storage server, and I'm not really to sacrifice 10GB of RAM (1GB/TB of storage if I'm to believe what I find through Google) on my home desktop just for it when the vast majority of my data could probably handle a rotted bit or two.

Please explain where this number comes from. I run ZFS on boxes with as little as 4GB of RAM, which are also doing all sorts of other things in addition to ZFS.

As with all filesystems on Linux, more RAM means more cache, and if you have free RAM you will benefit from a dynamically resized filesystem cache. That RAM is however not required and the cache can be evicted under memory pressure.
I am also grateful for PortableApps.com. Along with Scoop and Homebrew, they make using a system without root or admin privileges a really nice experience, in both Windows and Linux.

Mars is constantly moving. There are wind storms, dust devils, ice melting, all kinds of things.

Here's a dust devil https://www.youtube.com/watch?v=k8lfJ0c7WQ8 (again, it's still images to make a video) but not because "nothing ever moves on Mars"!

Mars is constantly shifting and changing with its weather and seasons. Ice caps freeze more, and ice caps melt more, water or other liquid flows down hills when it gets warm.

More often than dust storms, a new robot comes down to land on Mars in firey rocket-landing-fueled or bouncing-ball style. Movement.

Mars is constantly hit by rocks from space that create craters and push dust up into the atmosphere.

I've never heard someone say "Nothing ever moves on Mars" because it's really not true and a total lack of imagination. Maybe people think nothing moves because we haven't sent video cameras yet? But...Mars is constantly in motion.

Waveshare is really great for making eInk accessible to makers. I've got several of their products and I love them. Design and documentation are excellent. For most products they even provide libraries and/or sample code. I usually order from them directly, though it comes from China it's fairly fast compared to aliexpress and the like (think more like 2 weeks than 2 months)

By the way, one thing I don't get is why the pictures have such low saturation but the "demo" view shows really excellent saturation. Are there constraints when mixing colours perhaps?

Edit: This was explained below by sparker72678: https://news.ycombinator.com/item?id=23900165 . I didn't know they worked this way.
Interesting tool! And you've definition given a lot of thought to many of the problems encountered while attempting to do UI testing automation.

I've written my fair share of extensive selenium stuff (and appium, but.. let's forget about those painful memories) and one thing that I found fairly "easy' to add to the suites I had written was accessibility testing (using Deque's Axe[0] tools). It literally took a few lines of code and a flag at runtime to enable the accessibility report on my Jenkins/TestNG/Selenium combo.
However WCAG is constantly changing and it's hard to keep up, and even Deque is not always up to date AFAIK.
Do you have plans to have accessibility testing with your tool ? (even a subset of WCAG's rules)

Another thing I've noticed is the jump in pricing from Free to 100 USD/month which goes from 30mins to 6hours.
This might be steep for a team attempting to test out the validity of the tool against the competition - perhaps offering a first-month discounted trial or something like that would be appealing.

I also haven't really seen if it is possible to enable concurrency (for example, is testing on three platforms at the same time for 10 minutes on that free tier possible? I would imagine so if one is doing the lifting with CI like Jenkins - but perhaps you have your own solutions). Tangentially related but you say your tests integrate with various CI solutions, does this mean one can extract the test results in a way that allows further processing and integration into other tools? (I'm thinking of the XMLs coming out of TestNG there).

Lastly, I don't know if the time used is counted from the moment you start your VMs or browser starts, or the page is loaded, or the first step is done or something else. Clarifying that might help with a team's estimates (I had internal tests where the struggle was entirely on having the virtual environment/device/browser ready and the test was then a breeze, so the significant metric was the boot-up time).

It's a serialization format. It doesn't claim to be anything else. When people use it as their application's heap data model, they're misusing it. People are lazy and love to use their wire format as an internal data model (no one likes writing converters to/from the wire format), so this problem plagues everyone, but wire serialization is a fundamentally different problem from representing data within your application. When you conflate these problems, you get abominations like Java Serialization.

We should not expect indefinite immunity. With other human coronaviruses that cause colds, immunity typically doesn't last forever, so you can catch the same coronavirus when it comes around again a few years later.

This is not yet known about covid-19. But the claim that you can get it again "three months later" is eye-catching in how short a period that is, and hopefully is quite rare.
So, false positives may not matter in some conditions. Ireland is currently reporting anything from 5 to 30 cases per day, doing anything from 3000 to 10000 tests per day, and has capacity for at least 15000 tests per day. If the app doubles the number of tests being done and finds a few new cases, that's fine; it's still a lot better than NOT finding those cases.

These apps would, granted, be far less useful in places with major ongoing outbreaks and inadequate testing infrastructure; lockdowns should be used to bring numbers down to the level where this sort of thing is workable.

(1) is probably a greater problem. Ireland has about 30% uptake, which probably isn't enough.

due to long term sequilae as well.

How much more can we expect if things simply “get back to normal”. Hard to say but obviously a gigantic loss. I’m also highly skeptical of claims that #1 suicide, crime, violence have increased significantly. Source? Poverty/economic disruption is obviously a massive damage that cannot be understated either.

But I’m highly highly skeptical that countries who try to ignore the problem like Brazil, USA will end up economically more successful than countries with strong countermeasures like South Korea, Taiwan, New Zealand, and many others. Beat the virus to fix the economy.

At some point there is an inflection point where it makes sense to “give up” and accept that countermeasures are more costly than the benefit they provide. Clearly every day we delay and have high rates of infection, and the longer the vaccine takes, we move closer to the “give up” side of the calculation. I’m not at all convinced we’ve reached that point yet and we certainly hadn’t reached it at the point the federal administration gave up.

Actually I wonder why we should have a vector video format in the first place. Would it not be much simpler to render a series of vector images and their transformations directly to a standard video code? I mean all the modern video codecs have vector elements afaik, and most have motion prediction. One could just leave out the whole messy inference and directly tell the decoder "here is a rectangular shape, moving with that speed in this direction", no?

This is something more online media outlets should taken into consideration, especially for their own articles. Too many think linking out to potential 'competitors' is a bad thing, or make it too difficult to find the source for their data/conclusions.

Newspapers and magazines are especially bad for this, as are YouTube channels and other video format content creators.

It is good preliminary news. The real question if this vaccine prevents you spreading the disease or effectively turns you into an asymptomatic spreader. There also outstanding questions if this works well for elderly people, as vaccination are generally less effective if you are older. Basically news worth a small cheer, not an exuberant celebration quite yet.
Outside of publicity, I don't see this as having an enormous impact on profits. Companies will be compelled to produce the vaccine in any event, and will be compensated, but I can't imagine governments would be purchasing the vaccine for any large markup.
So, elderly people are less likely to use a smartphone (though I suspect not THAT much less likely). But the people they come in contact with probably do use one, mostly. Generally these should work on any smartphone under five years old.

Overcoming the Innovator’s Paradox
You're right about Kindergarten being a very important part of socialization. I've honestly never really heard of people skipping it outside of kids who were bored and needed actual work to keep them occupied.

But my point is that school, at least K-8, for the parent functions both as daycare and education. The pandemic and virtual classrooms is making schools provide the education but not the daycare and we're seeing how unprepared the US is to lose this service for a while. Parents still have to go to work but also can't just leave their kids at home alone, and having someone stay with them 9-5 to keep them focused on school is more expensive than a lot of families can afford.
> Having GPT-3 render a first draft of books in the archetype you mention (one simple idea stretched out over many pages).

Given what I've seen so far with GPT-3, that simple idea would have to have already been discussed at length on forums on the internet and in the corpus.

Usually books have facts and studies that they use as supporting points. Many of the connections they make between the subject material and their thesis are unique, and this forms their supporting argument. GPT-3 is rearranging words and sentences to resemble structures it's seen before, but it does not create novel facts.

The Problem with ‘Anti-Racist’ Movie Lists
> the comment is a shallow dismissal

> two parents working full-time, with a single child, do not have the resources or additional children required to provide a classroom environment

You said your children need childcare as much as education. If you don't have the resources to provide what you believe your children need, perhaps you shouldn't have had children. If you want both parents to work full time, there's certainly an expectation that the children will need care. Why did you assume the state (read: your fellow taxpayers) would or should subsidize that? You are reaping the benefits of having children without bearing all the responsibilities. This situation is simply revealing the negative externalities many parents force on their neighbors.
