The difference is that they can ride out a supply chain interuption for months for non consumables that aren't a direct part of the manufacturing process.

Giving them time to find alternative suppliers for things like computers and pencils.

If they instead depended on consumables like say zipper teeth, they would have to shut down almost immediately in the case of a supply chain interuption.
Doesn't adaptive stream quality or any form of responding to congestions require the link to be saturated first. At least I don't know how it should detect that the link is almost saturated but not quite yet. So every time it detects that the link has been saturated the damage is already done.

Compared to say, just capping the quality a certain amount below the current maximum for a while. For example turning off the 4K stream for the next 2 weeks. I guess people can live with HD for a while.
That's a self-fulfilling prophecy...

And similarly, within a microservice architecture the tail latency is amplified through all its downstream requests or if there is fan-out:

Consider a system where each server typically responds in 10ms but with a 99th-percentile latency of one second. If a user request is handled on just one such server, one user request in 100 will be slow (one second). The figure here outlines how service-level latency in this hypothetical scenario is affected by very modest fractions of latency outliers. If a user request must collect responses from 100 such servers in parallel, then 63% of user requests will take more than one second (marked “x” in the figure).

Blockchain works for currency problems because the unit of tracking is the unit of value, the entire system is fully self-contained and no oracle is required to pump information into and out of the system.

For things that do not interface directly with hardware it's great. I use WSL daily for development.

The best part of any Linux distro is the terminal, I've ditched my Linux laptop for a Windows laptop with WSL and haven't looked back.

I've been pretty tired of linux desktop environments being flaky, lack of gaming, Nvidia driver issues, etc. Windows + WSL has been a godsend
Humans still have to read these things. Getting policy makers to pay attention is an actual problem, so using 'plain talk' can be effective.
No it wasn't, WSL1 is a Windows subsystem. For running Linux.

I think "Windows Linux Subsystem" would've been more accurate, but it's also more confusing.

I'm also a bit disappointed it doesn't bridge the host network like WSL1. It's nice there that I can just run something and access it on local host - it even works together with docker-for-windows, the docker CLI client being in WSL.
That's the direct peering part I mention. It's up to the parties to hash that out bilaterally on a case by case basis, there shouldn't be a need for netflix to throttle things across the board.
> I'm fairly certain I've just recovered from COVID-19 given my symptoms, but can't get tested here in Colorado.

I'm glad you're better. Please be careful going forward, though. You shouldn't assume you have an immunity unless you have a positive test result.

Even with the strict pre-test screening that focus strictly on high probability patients, some locations are reporting very high (90%) negative test results from assumed cases.

It's best to continue practicing safety cautions as if you did not have a COVID-19 infection
WalMart turned their supply chain into a competitive advantage 30-40 years ago. I saw it as an employee first, their inventory control in the store was ridiculous back in the 80's. Then I saw it again working with an EDI shop (Sterling Commerce) in the 90's. Everything was electronic. We'd get these little mom and pop shops calling in trying to get their bisync modems working so they could upload their ANSI X12 810's.

The only reason there's any question who's the richest person in the world is that Sam Walton is dead.
>but they've achieved it at great effort.

And enormous expense. You shouldn't have to have Apple money to establish visibility into, and security of, your supply chain. I mean, do you really want to be down in the weeds trying to make sure the coltan isn't essentially coming from Rwandan warlords? Apple can afford that, most people can't.

Definitely time to rethink globalized supply chains. The centralization inherent to this obsession with efficiency is simply not resilient to disruptions. We learned to build redundancy into our food production to handle disruptions like, centuries ago, which is (partly) why we pay farmers to produce more food than we technically need. We don't invest much to keep manufacturing of some other critical goods domestic.

I'm frankly astounded that exclusively outsourced supply chains were ever a serious consideration. Yes they're more efficient, but efficiency isn't the only consideration. Imagine if someone seriously came forward to suggest China should also produce all of our food. It's nuts.

I blame the continued financialization of our economy which leads to an absurd obsession with efficiency above all other considerations. It's yet one more example of borrowing against the future that has led to many of the recent economic crises.

Edit: we regulate risk in financial sectors, like the debt ratio, and supply chain resiliency is simply another risk assessment. I think more comprehensive legislation surrounding corporate risk taking will ultimately be needed.

By comparison, Saudi Arabia produces 12 million barrels of oil a day: if the price drops $30 they need to make $360 million per day to cover that, or $30 billion if they carried out the trade over a three-month period.

If the total single-name CDS market is $10t and $1t of that is in oil and gas firms...it doesn't seem out of the question you could get a $30b position. Not that I really believe this is what's going on.

Even HD streaming from Netflix requires around 7 megabits of bandwidth. That's not too much. If the internet infrastructure is struggling the handle that much throughput in 2020, it's the fault of ISPs, not Netflix.

Streaming video content has been ubiquitous for years now. A lot of households probably have 3-4 devices streaming HD content for hours during "prime-time." So ISPs should have kept up.
Wait, what?!

What ever gave you the idea that there is a dearth of fiber in Europe or that there are only DCs in Ireland or the Netherlands?
Very. In the numbers above, 76% of page views are from users not logged in.

I was surprised it wasn't even higher, since I remember it as having been 95% in some past analysis. This is more likely because I measured it differently than because something massively changed.

ISH looks great. If I was still using any iOS devices, I would give it a try.

I really wish iOS / iPadOS supported better software development environments and tools like ISH. Hopefully ISH does not get pulled by Apple App Store regulators.
Yes, but that's how TCP/IP (the Internet) has worked successfully for 40 years.

Basic congestion control uses packet drops as a signal of congestion and slows down. You get packet drops if a queue was filled somewhere, which would be the bottleneck between two stations. That's business as usual.

The best queue to fill is as close as possible to a station, i.e. in the user modem or first hop, if not the application itself. If we begin to get congestion between ISP networks it won't be as pretty but it won't "break the Internet" and it's literally their job to upgrade the connectivity between networks before that happens. Plenty of bandwidth means you don't need QoS.

That being said, there are modern congestion control algorithms that try to be more clever. Your web browser may already be using one of them.
There are no interactive elements, I just enjoy using React more than the alternatives, even for static content. Instead of asking "what requires react", a better question is "what are the tradeoffs of using react in this situation". In my case React allows me to use Gatsby, a wonderful static site generator, and it also makes it easy for me to add any interactive content I want in the future.

My site will load fine without javascript, so it's hard to imagine react is slowing things down much (although if you've visited before the PWA will mess it up if you try to turn JS off).

For something like Wikipedia, time to interactive isn't that important (which is good, because lighthouse tells me that this page [1] has a TTI of 7.4s). First meaningful paint matters much more. I really disagree with the narrative that anything written with React is going to have a much worse user experience compared to the "old" stack.

Skylinesort
thanks for the suggestion, i will add another example like this.

Skylinesort is a novel sorting algorithm that sorts integer keys. It outperforms current sorting algorithms when keys are clustered (not uniformly randomly distributed). I showed it to some profs at Stanford, and might publish it formally.

It sorts in time O(ku-ulog(u)+n), where k is the number of bits in each key, u is the number of unique elements, and n is the total number of elements.

It certainly confers immunity for a short period of time. How long that immunity lasts for is unknown, but it’s not unreasonable to start with an assumption of “at least a few months”.

There’s also not strong evidence that there are two sufficiently different strains. Viruses experience small, mostly meaningless, mutations with great frequency. The research talking about S and L types are actually just an arbitrary categorization of many different mutations of the virus.
I have seen many doctors, including sleep specialists, regarding insomnia. They all pointed to one source as the reason for the sleep issues: stress. And they all wanted to put me on prescription sleeping pills. I said no to that. Sleeping pills are addictive and you have to take them for the rest of your life. As a software developer, I am used to finding and fixing the underlying problem as opposed to the quickfixes these doctors were offering me.

After much research I figured out the underlying problem, and the fix for it. The underlying problem is magnesium deficiency. As a software developer I am using my brain more intensely than most people. This is the stress the doctors are talking about. Stress depletes magnesium. The cells in our body depend on two essential minerals for normal function: Calcium and magnesium. Cells go into ON state when calcium goes in, and OFF state when calcium goes out. Calcium doesn't go out on its own: magnesium has to go in and displace the calcium. When you are low on magnesium, cells can't go into OFF state. When that happens your muscles become stiff and you need massages, and your brain can't turn off and you can't sleep. The solution is magnesium supplements. This fixed my muscle stiffness issues and my sleep issues. A special compound of magnesium called magnesium l-threonate is especially helpful for sleep because it can penetrate what is known as the "blood brain barrier".

Scientific sources for this are hard to come by. I had to piece together all this from multiple sources. Here are some:

https://www.westonaprice.org/health-topics/abcs-of-nutrition...

http://www.drsinatra.com/benefits-of-magnesium-supplements-f...

http://paleoforwomen.com/soul-crushing-stress-and-the-miracl...

https://www.ncbi.nlm.nih.gov/pubmed/23853635

https://www.ncbi.nlm.nih.gov/pubmed/8232845

Your mileage may vary. Magnesium deficiency turned out to be the cause of my insomnia but may not be the cause of yours.

How is “I have trouble sleeping” vague? It’s quite precise and clear.

The _why_ of the sleep problems is separate from the _fact_ of it.

Whether the _why_ is suitable to mention is totally context-dependent. In some situations it would make sense to mention the why. In others it would be weird and going into too much detail.

And it’s not just nerve discomfort. It’s muscular and there’s all sorts of details that are not easy to describe if I want to actually explain what it is.

Finally, you’re assuming that mentioning the reasons would somehow mean people wouldn’t then make assumptions, and this is false. If I mentioned the why they’re likely to assume (I know this from experience) irrelevant causes/cures to do with pain (much of the problem is very different to pain), pillows, mattresses, yoga, etc.

I have also found that it does not matter what you tell people the causes are, many will not let go of the idea that the sleep problems must actually be the result of psychological causes, due to being unable to relax, a restless mind, poor sleep hygiene, etc.

Most applications will never be architected to be “properly distributed” because of cost. Many popular web properties (Reddit) still have outages on AWS even when architected properly. Netflix still distributes content from their own CDN with their OpenConnect appliances, and only uses AWS for non streaming use cases (jedberg will correct me on both Netflix and Reddit points if I'm missing something and comes across this comment).

https://www.usatoday.com/story/tech/news/2017/02/28/amazons-...

If my app is architected for reliability, I’ll run it on bare metal and keep the costs savings. Why pay twice by building it for cloud durability and running it on expensive cloud resources? Clearly the AWS marketing is working (“you’re just building it wrong”).

We’ll see what happens when CFOs take the reins from CTOs and CIOs and start putting cost controls in place during this recession (“why exactly are we paying so much in opex when this could be capex we can depreciate?”).
They were talking about abysmal testing rate:

”We estimate 86% of all infections were undocumented (95% CI: [82%–90%]) prior to 23 January 2020 travel restrictions.”
No doctor here but maybe the rigorous schedule to go to sleep is what really made a difference. Sleep hygiene is a lot just controlling the predictability of the sleep environment and time it happens.
