Just two words: cost and benefit can help you to understand the value behind quicker tests.

Flights are getting cancelled already, and some countries closed their airports at all. There are places where you can get stuck at a border crossing, or a roadblock if you have no proof of a recent medical checks. On this background any tests which add 15 min, or even 1 hr overhead sounds more like a solution, not a problem.

Quoting the linked article: "I've thought for a long time that, for some types of apps, a Mac app would do as well as an iOS app." Isn't it pretty clear that when he's asserting that the relative downloads of NetNewsWire for iOS vs. macOS "confirms" that thought, he's (a) describing that as his thought, rather than trumpeting it as an immutable fact, and (b) both admitting that this is just one piece of data ("admittedly just one app") and confining even his hypothesis to "some types of apps"?

tl;dr: I get what you're saying, but I think you're giving too ungenerous a reading in this specific case.

Couch Theory
I have been trying to man my way through getting a couch through a doorway, I exhausted all mental capabilities of visually the different ways in which I could perceive it could fit due to moving several pieces of furniture in my life, I am now stumped, stumbled apon this sit and feel I may be able to be helped here.
I have a couch that is width = 205cm height = 77cm depth = 105cm and I am trying to fit it through a door way that is width = 81cm height = 207cm, and am trying to figure out if its possible.
More details, there is a front door at the end of a hallway, coming through the front door 28cm in perpendicular is the doorway in question then another wall of 82cm and then another doorway and then again more hallway. Parallel to this wall is another wall going for 118cm then a 120cm archway then more wall, through the archway is a large loungeroom where the couch in question currently sits in limbo in the middle, question here is if it is actually physically possible to perform this task with out dsimantling the couch (not possible).
I know there is a mathematical way of solving this, it may be quite simple Im not sure, I just dont see it, if I could get some help on this that would be so so greatly appreciated, explanation too if possible :)
For purely photo Nikon has gone from “no reason to exist anymore” to “tolerable”. But if you care about video it’s hard not to view mirrorless as a two horse race between Sony and Panasonic. (Sony is much better at the full frame/high end in a lot of ways but Panasonic offers a ton of value for the money; my G9 is a tremendous performer for both photo and video.)

Yes, we need laws against this and for the gatekeepers to be the enforcers. I used to think that individual choice would solve these problems, but it won’t. Zoom et al are growing like a weed and we can’t protect all our loved ones from this bullshit with individual action all of the time. There are some problems that require government action; I think the events of this year have demonstrated that clearly. Individually we are weak as water, but collectively we are embarrassingly powerful. Time to organise.
Canon makes their own APS-c and fullframe sensors, but they use sony sensors in their smaller cameras, including their "premium compact" g7x and similar cameras, which use the imx183 or imx383 sensors, similar to the sony rx100 series.

How to Bring Targeted Traffic to Your Website
I think "shallow" is being a bit uncharitable. The book here doesn't dive into ditributed systems theory very deeply but it gives a very rich overview of real industry tools used over the past few decades with plenty of context around why technologies are being used or discarded. They go into code examples of things like CRDTs so its not like its just prose.

One thing that feels off to me as a backend engineer that deals with distributed systems in practice is no treatment (AFAICT) of containers/virtual machines and how tools like kubernetes are providing the primitives that the distributed languages of the past provided. In general I think chapter 4 doesn't have a cohesive narrative on its treatment of languages for distributed computation. I know this is messy topic but I think more could be done to tie things to current art.

If I were to make a prediction, there's general trend towards protocols (mostly network level above layer 4) being the actual thing of interest for distributed computation, not single language runtimes. Wire-compatible DBs like AWS aurora and MySQL are an example, but also I think things like container orchestator's liveness and readiness checks over HTTP. As more primitives rally around the same core concepts, I think the general trend will be to go from conceptual similarity, to client library compatability (e.g. identical interfaces a la OpenTracing <> Lightstep, Jaeger) and eventually wire/protocol compatibility. Language runtimes are too much of a moving target as there are other pressures at play (community, tooling, typing, yes even syntax) that go into language choices over a decade.
It should be noted that Sony does supply sensors to Nikon, but in Nikon's flagship cameras, the sensors are designed/specced by Nikon, and Sony build them sensors to that spec, and those sensors are not used by anyone else. It is definitely not the case that Sony is just grabbing an already-designed sensor off the shelf for Nikon. And it is pretty much agreed that the Nikon d850 has the best image quality, period. Sony isn't using that sensor in their own cameras, they are not allowed to.

What if mobile platforms (iOS, Android... ) changed the security/privacy policy so that apps had to request the “network access” permission, either whitelisting domains they want to talk to, or askingfor wildcard access?

Most apps shouldn’t need wildcard access, and the mobile device could include a warning when an app does this teaching users that they should be careful with the app.

This way at least when you installed Zoom for example, it would say something like:

“Zoom is requesting network access to:

- zoom.us
- analytics.tracker.example.com
- facebook.com
“

And then at everyone would know. It still doesn’t solve the underlaying problem, but it would probably make companies more reluctant to add third party analytics and sdks.

So do modern Linux pipes work bi-directionally? Of course the shell doesn't use them like that. But that does not necessarily mean that the kernel wouldn't support it. I vaguely remember that a colleague used a pipe bi-directionally between 2 C programs he wrote. To my surprise it mostly worked. IIRC there were some minor issues make him giving up the approach. The big surprise for me was that it worked at all. Or is it just racy beyond all control that you read back your own data if the other end has happened not to empty the buffer?

Great tool to generate slick wikis quickly. So, if I connect a sheet to polymer then what's the output? the whole website is generated by Polymer which is then connected to a custom domain? A video demo of your tool/dashboard would clear some doubts.

Also, in the no-code tools area, people use Airtable with integromat/zapier, Webflow to make websites. So, in case you do generate the website, then I think it would be make sense to market/target this as a no-code tool too, it would gather interest from the no-code community quickly .

Mirrorless is electrically and mechanially a MUCH MUCH MUCH simpler design (SLR is essentially two cameras in one, with the pentaprism allowing light to go to a second sensor used for autofocus, and also to your eye) and it has a lot of compromises in complexity, reliability, and performance.

Mirrorless allows the camera to use the image sensor itself to do all the work. That means autofocus can be much better, using every pixel on the sensor for autofocus. It means you can run computer vision software in real time to do fancy things, like finding out if there are eyes in the image - most likely, you want the eyes to be in focus. You can focus in near darkness, when it's too dark for you to see. And other stuff.

The biggest downsides are 1) the electronic viewfinder, these are not as nice for most people, but with the big caveat that they do allow you to frame an image in near total darkness where an SLR wouldn't allow you to do that and 2) the big one is battery life, it is 5-10X worse with mirrorless than with SLR.

same goes here, as part of the history taking you can get a test to see if they have CV or something else.
Lenders and credit investors are still very liquid at the moment; it's not a financial crisis and it's not at all the case that noone is willing to lend. But noone will lend to/invest in the credit of a non viable prospect and there will be more scrutiny about what's viable in current circumstances. The price of money has also gone up (despite central banks' best efforts) so there will be more discrimination between strong lending/investment propositions and weak ones, and the cost will be higher for everyone.

Yes, xv6 is great. The original post here already has a brief section on the code from xv6/pipe.c, which made for pleasant reading after I had just finished working my way through the 6E code.

I also looked at the pipe implementation in Minix, which is a (non-trivial) variant of John S. Dyson's implementation that the BSDs share. It is implemented as a server (in the microkernel sense), so there's quite some added complexity there in handling "vmount"s and locking, but there are still some familiar elements of the code too, such as the "put it all together with flags" code in create_pipe().

https://github.com/Stichting-MINIX-Research-Foundation/minix...

For something even further along these lines, there's also the pipe implementation from Plan9, which at first glance felt so unfamiliar that I wasn't sure I was looking in the right place:

> completely normal rooms in working class homes

My impression is that virtually all of the Airbnb complaints (both from guests and from neighbours) relate to "entire apartment" listings and/or the "private rooms" where the owner isn't on site.

There was once a time when most of the listings were for spare rooms in someone's house/flat, and to me that was kind of the whole point of Airbnb in the first place.
Not helpful though if you want to move large files quickly.

> The harder you make it to start and run a small business, the fewer small businesses there are, which means everyone works for and is a customer of the same increasingly small pool of ever larger businesses. Which means that money and power continue to concentrate in the small group of people that run and own those businesses.

I don't necessarily agree with this. To attack this argument from another angle, there are many European countries out there that have a thriving small business economy while also placing a lot more societal burdens on them.

In America as we're seeing with the coronavirus, a lot of these small businesses are barely solvent. That's even in spite of us giving them almost no responsibility to their workers, so theoretically the barrier to entry for a small business should be as low as possible. Yet the coronavirus is causing some hefty damage to those smaller businesses because as it turns out, many of them were one crisis away from dying.

I don't think the issue has anything to do with the difficulties of starting a small business but rather the difficulties of having to compete with larger companies which have a lot of their costs negated by the economy of scale they operate at.
