The only way the velocity (number of cases) would go negative is if they discovered a disproportionate number of false positives or (number of deaths) if deaths were discovered to be due to something else [or people came back to life]. As time goes on, the velocity will reach a constant of 0, presumably. The acceleration at a constant velocity is 0.
>Modern digital camera sensors are good enough they're somewhat limited by the lenses.

In what way? Smartphone sensors have the highest pixel density and they can still resolve an amazing amount of detail through their not-so-great tiny lenses. When it comes to ILCs, everytime there is a bump in sensor resolution, it is entirely possible to extract more detail from the same lens (provided its was a good lens to begin with). And ILCs are still not at the level of pixel density as smartphones, so there is quite a bit of room for improvement.

> So if you have several times the size of a "full frame" digital camera, you can achieve better results with 1940s technology

Not exactly because larger sensors mean larger lenses because of the larger image circle, and then you have a manufacturing challenge of grinding and polishing an even larger amount of glass, so it doesn't scale linearly like that.

Amazon Fresh (until a few days ago) was releasing slots 3 days out each night at midnight, so I've been saying up to place orders. Now it seems incremental throughout the day, but I've gotten lucky and nicked a spot. However, they don't have everything I need even normally. Now, it's even worse, so I have to order from multiple places. The local Mart's that deliver are still opening their slots at midnight, though usually for 8 days out, and again items ordered often go out of stock before delivery. It feels like a sureal video game.

A bit off topic, but regarding the railroads:

A big chunk of US rail traffic demand over the last decade has been oil, which was already dropping as pipeline construction caught up with demand under the new administration's pipeline policies.

(Tangent: For those not familiar, check out Buffet's meeting/deal with Obama admin re: pipeline policy after Berkshire picked up UP stock for cheap.)

The railroads enjoyed a virtual monopoly on additional oil transport capacity for years, but I suspect the latest drop in oil demand might signal the last element needed to completely end that era.

If true, then they might see a slight/temp bump in rail demand in a few months as petroleum storage fills up, when tanker cars are repositioned as a last resort storage option for over-supply.

Point being, the abrupt drop in rail traffic likely has more to do with the drop in oil demand than grain or any other rail transported product.

Which you could still ultimately blame on covid, but it's not necessarily representative of a collapse in multiple markets. Just oil trimming the excess.
> e.g. constantly having to allow applications access to files outside the initial default sandbox.

Any system that has ordinary users trying to do this for ordinary software will fail.

Things like apparmor can work well because the author or distributor of a package knows that it shouldn't ever do a particular thing, so if it attempts to, that is a bug and it should be refused. The user shouldn't even have to be aware that this is the case because the program shouldn't even attempt to do the thing the author/distributor asserted it will never do.

> It also seems clear that this concept ultimately heads towards signing application binaries, like macOS.

Linux has had that for years already. Packages are signed by the distributor. Nobody complains about it there because the device owner can authorize additional parties to sign packages for their machine, as it should be. Have a look at the install instructions for Signal Desktop for Debian on signal.org -- "sudo apt-key add" etc.

You can also install binaries outside the package manager, and then the filesystem executable bit serves a similar purpose -- disabled by default but the user can override it.
That's not even the case in this story though - the implementation was faster, for the usual way it was used.

Yep, that makes sense. I’ll say most marketing books I listen to that are 10 years old are brutally out of date.

The focus on detail that made the book a success also made it go out of date relatively quickly.

It needs an update. That is on my to do list most years (between running MicroConf and TinySeed) and one of these days I will circle back and get it done.

Honestly, this weighs on me. It’s something I’ve been wanting to do for years.

> Germany is now testing 400k a week (I think that is what your number is referring to).&

> Another poster mentioned the decentralised nature of the German system, that has been mentioned as one of the reasons why Germany was able to test so much.*

Seems to be, but that makes Austria's excuses look a bit poor. Here they have a similar decentralised system, but they're claiming that they don't get enough test kits on the market and that's why they're now testing 3k-5k a day despite having lab capacities >15k/day. If Germany can get them, Austria can, too - money shouldn't be an issue.
I can't make sense out of your argument, grammatically. Can you rephrase it?

Clearly, you've never been to Japan ;-) We've got $50 grapes! And that's for one grape... not a bunch... But I think you are correct that most North Americans especially are geared toward buying the cheapest produce available, often regardless of quality or production methods. I think it's slowly been changing over the years, but people still baulk at paying prices that would sustain small family farms without imported cheap labour. However, every time this kind of discussions come up, I feel it necessary to point out that vast majority of cost in food production is distribution, not production. This is due to the practical monopoly on food distribution that some companies have. You could actually raise the production price a pretty hefty amount without affecting the final price terribly if you regulated the distribution. Of course, what would the poor Cargill's do? They wouldn't be able to have swimming pools full of money. That won't do...

The other main reason is that upgrading the tooling for sensor fabrication is super super expensive, and Canon has historically used the high-volume entry level camera market to subsidize this, while sony uses their smarphone business to subsidize it. Canons entry level camera market is tanking just like everyone elses which probably made them weary of such investments in the past few years (till Sony came and stole their lunch). It seems like they've decided to go for the high end high-profit segment. I'm super interested to see what kind of sensor there is in the R5. They're probably not at A9 read-speeds quite yet, but it will be interesting to see how close they've gotten.
I’ve just been going to the grocery store as usual and it works great. You show up in the morning and there’s no line yet and shelfs are full. Later in the day they meter entry so you can keep distance inside.

I am always uncomfortable with high "big O" algorithms. For example I know that with the data we have now, O(n^2) is fine, but if there is no strict bound on n, we don't know how far n will go in the future. It may also be a vulnerability, where the attacker uses data that is designed to exploit the worst case scenario.

It is more about peace of mind. By using the more efficient algorithm (by asymptotic complexity), I know that my code won't become a bottleneck. That's like using "size_t" instead of "int" in C. I know my array will not exceed 4GB in any practical application, but by using size_t, I know it won't crash if it happens one day. One less thing to worry about.

Almost all well designed libraries use hybrid approaches, switching from an algorithm optimized for low level efficiently for low N to a theoretically more efficient algorithm for high N. For example a sorting algorithm can go from insertion sort (good for low N) to quicksort (very efficient most cases) to merge sort (guaranteed nlog(n), highly parallelizable).

You might have heard that correlation isn't causation? It's a very common statement, that people think they know the meaning of. But the way it is always used is, this correlation isn't causation, because I don't like it, and that correlation is causation, because I do like it. In other words, special pleading.

If something is not causative, which you seem to acknowledge in your example of "gene X", then why exactly do you attribute a correlation to something other than coincidence? What is coincidence, anyway? Einstein said coincidence is literally the only thing anyone ever experiences, in a literal mathematical/physical sense.
> What? How could a cat pass anything on to a rat?

Everybody poops.

Everybody eats and drinks.

Sometimes these two overlap more than is sanitary.

It's not a virus, but check out the parasite toxoplasma gondii for an example of an organism that uses this mechanism to get from cats (it only can reproduce in cat intestines) to rats (where it lives in their brains).

It needs to get back to cats from the rats when it is time to reproduce, which is the really interesting part of its life cycle. It doesn't just wait around on the off chance a cat will happen to eat the rat. No, it alters the rat's brain to make the rat lose its fear of the smell of cat urine. Normally, rats avoid territory marked by cats, but not those with a toxoplasma gondii infestation. It even makes male rats confuse that smell with that of a female rat, so they actually end up seeking out cats.

Truly something out of a horror movie [1].

Lots of security issues are fixed not by “fixing” them but by adding mitigations which include user approval, surfacing otherwise hidden activity, and other crutches. At the end of the day it is an automated system and must do things without the human in the loop, so the best you can do is make “the loop” visible to the user.

Interesting because in those examples the need for reuse was so high that not only is the code reused but an entire company is set up, paying staff including sales and marketing people not working on code itself but making people aware of the solution. In fact there are multiple companies providing each of those services.

I went to Affinity Photo for certain photoshop-like things: very happy with how it's working out, within limits. No hesitation there.

Clip Studio's a special case. For certain uses, such as cartooning/comicing, it is WAY better than anything Photoshop can offer. I've got that as well and look forward to digging into it further, but even with extremely basic familiarity the tools for building panels/folders and speech bubbles in Clip Studio (or pretty much anything for a cartoonist/manga artist, especially if you're targeting black and white printed output) are so far beyond Adobe stuff it's quite silly.

I daresay there are parallels for UI people with Figma/Sketch or what have you. I can speak to the Clip Studio situation (and I'm also happy with Affinity Photo for what it specializes in).
I've been in discussions about internal applications with few hundreds users and very moderate amounts of data being shuffled and stored and some people, of various backgrounds, are just so convinced that we need to go all in on Kubernetes, Microservices, Istio etc.

And all I can think about is "Hey, you could build this with a small team as a simple monolith and with proper caching you could probably run this on one or two raspberry pi, that is the amount of power you actually need here".

Don't get me wrong I do think they absolutely have their place and in other parts of the company we have much larger software development projects and they are absolutely making great use of Microservice architectures and Kubernetes and is getting a lot out of it. But that is 100+ teams building a product portfolio together.

We could not use prometheus remote storage adapter because of the following issues:
1. by the time you get there, it looses lot of information (like metric type, help, out of ordered drops etc..)
2. you do not have control over when it gets sent out, as it has to come through tsdb after chunking, this adds lot of latency.
3. It is per time series based protocol, not good for sending all the samples of a scraped target as a single chunk. Sending as a single chunk, helps you to group similar metrics at the remote side and simplifies the protocol for reducing the network bandwidth.

hence we did not use remote storage adapter. We introduced a new interface that plugs into the scraper directly.

• Somebody already tried and it was a disaster
