So at one point we where doing scale testing for our product where we needed to simulate systems running our software connected back to a central point. The idea was to run as many docker containers as we could on a server with 2x24 core and 512GB of RAM. The RAM needed for each container was very small. No matter what the system would start to break around ~1000 containers (this was 4 years ago). After doing may hours the normal debugging we did not see anything on the network stack or linux limits side that we had not already tweaked (so we thought).So out comes strace! Bingo! We found out that the system could not handle the ARP cache with so many end points. Playing with net.ipv4.neigh.default.gc_interval and the stuff associated with it got us up to 2500+ containers.
For whatever it’s worth, I can access HN from China right now.

You shouldn't actually ever change a story in progress if you can avoid it. The feature is the feature. How you build it doesn't go in the story. And if you aren't sure how to do it, you account for that in the estimate.
It’s interesting that lambda still requires a nosql db for good perf. The example they link to from this article uses dynamodb. Not a great choice for a general purpose web app, where sql would be a better choice for many use cases.

It’s cool that aws has the data api for lambda to connect to aurora serverless. But then you’re stuck with MySQL instead of postgres, and also stuck with ~100ms db access times.

"Verified by Visa" is still in use - it just hit me up booking a hotel in Europe from the US. It really does look horrible, like an obvious scam site, but it's not. I really wish they would get rid of it. It actually makes me feel a lot less secure every time it pops up.

Thanks for the detailed answer. I am from a developing country and my water usage is indeed closer to 150l than 400 l. Personally, this peaked my attention because I moved to a new city just three days ago; the city is on the coast and struggles with water supply. I was wondering how expensive such a system is today.

I did think of energy usage but didn't find easy number to quote. The wiki link suggests 6.5 m^2 of thermal concentrate and 75 W solar panel is enough for the energy needs of 150l/day in 2011. This is not that difficult for a remote or urban house, and will cost less than a few hundred dollars https://kenbrooksolar.com/price-list/solar-water-heaters-pri...

Higher public expenditures on health care for poorer outcomes?
Last sentence in the article:

>Amazon has several requirements for third-party sellers on its website: They must provide a business name, address, contact information, a valid credit card, and tax identity information.

It doesn't seem like that difficult to comply.
Firstly I'm only speaking about England. I don't know what happens in Wales, Scotland, or Northern Ireland.

Clinical Commissioning Groups should be following NICE guidance. If NICE looks at a medication and says it doesn't provide enough advantage for the cost they won't recommend it. That means CCGs won't always pay for it, and so hospitals can't use it.

Sometimes when NICE recommends a treatment the patient has a legal right to it, and the patient can pursue treatment if their local CCG is trying to avoid paying for it.

This cost:benefit calculation appears to be what's happening in the US. Except over here it's a public body making the decision and over there it's a private company.

Here's the NICE page for Pomalyst: https://www.nice.org.uk/guidance/ta427

> Pomalidomide, in combination with low‑dose dexamethasone, is recommended as an option for treating multiple myeloma in adults at third or subsequent relapse; that is, after 3 previous treatments including both lenalidomide and bortezomib, only when the company provides pomalidomide with the discount agreed in the patient access scheme.

That seems similar to the US? Only to be used after other meds have been tried, and only if the company supplies it at a previously arranged discount. (I didn't do much searching for this so maybe I've misunderstood the NICE guidance).

https://www.nice.org.uk/corporate/ecd4

> If NICE recommends the use of a treatment, the NHS Constitution says that it is your legal right to have it if your doctor believes it is right for you.

https://www.gov.uk/government/publications/the-nhs-constitut...

Very true! I think allowing receivers to block forwards would be a good starting point because:

1. They didn't ask for it in the first place.

2. If there is enough adoption, senders will be discouraged from sending them, when they know their forwards are being ignored.

For a more full fledged use case FRRouting may be the way to go. We are using Quagga here mainly to maintain internal routes with iBGP and route reflectors. This is a fairly simple use case.

Quagga is available in the default package managers of most distros so its a good place to start.

You've missed the part where 120 is divisible by 24. You can losslessly go from 120 to the other popular frame rates, including 24.

At best this is an uncommon opinion. I work with a dual citizen republican from Canada. He was almost swayed to your view until he actually used the us health system. We have good us Corp healthcare, & now he says it's similar to ca. He was wondering what would happen if he got hurt and lost coverage in the us.
> But he uploaded a video containing Nazi imagery while he said, more than 20 times, "Gas The Jews".

You keep on saying this because it sounds shocking to people who haven't watched the video, without the proper context it sounds bad i.e. It was clearly a joke intended to annoy his girlfriend.

I could describe the 2013 Wolfenstein games as "gruesome killing simulator that is full of nazi imagery" and without the proper context it would sound bad i.e. you are playing a guy fighting against a Nazi occupied Europe.

This is again incredibly disingenuous way to describe the video and you know it. That is why you continuously ignore the other parts of the video that explain the context. I find it pretty disgusting that you obviously know lots about the case and ignore the facts that don't fit your narrative.

This is exactly what the court did at the trial. This is why the trial was done with a magistrate and not a jury as if a jury saw it they would have probably laughed at it.
That is a succinct funny joke!

UK has a set of standard guidelines for how to treat diseases with proven drugs, and only pays for those (like the insurance company in the article being rigid about its guidelines).

People complained that their doctors weren't allowed to go off-track and make up special treatments for their special patients that went against guidelines (like the patients in the article).

Because it's political suicide to deny "What the doctor thinks is the best" when it comes to dying cancer patients, the UK government set up a special fund of money to let doctors go against the guidelines. It accounted for ~1/6th of all cancer drug costs.

It turns out that this special fund was largely a waste of money, the guidelines were fine all along, and patients were harmed by getting treatments that don't work.

Despite having our hearts in the right places, patients were harmed, and funds were taken out of some other (proven) part of the health care system. But because we tried to help, we won't bring this up very often.
Individual scientists get predictions wrong, consensus generally doesn’t since the dawn of modern science. If you research it you’ll see for example that global cooling was a minority view and the consensus at the time was warming.

Even the very first IPCC report from 1990 proved accurate in its predictions decades later because it was a consensus work. Climate predictions from the IPCC reports are accurate. There are decades of evidence.
> Isn't this just a weaselly way of saying that you're perfectly fine with poor people getting much worse care than rich people? What does it matter that they're getting better care than rich people did 100 years ago?

Why do you want to fight, friend? Maybe you perceive moral superiority such that it's easier to tear down than cooperate. Like I said before, that's a recipe for disappointment. Improvements in health care matters because that's a trend that is apparently still continuing. What am I missing?

And I'm not fine with cancer, another insult! Don't you get me yet, my friend?

I do know we're going to definitively cure cancer soon such that the treatment doesn't break the bank as it does today. Until that happens, let's work to bring down the costs AND help out people who can't afford what services are on offer today. Why not both?

> what it is about the current system in the US you don't like

I don't like how the health care insurance covers everything. The cheap stuff should be out of pocket so that individuals shop on price for those services and we build a competitive marketplace on the simple stuff.

I want up-front pricing for services in hospitals, and if I am of sound mind, I must opt into services before they are delivered. Finding out what services cost after I get them is one of the scammiest features of the current system.

I don't like how drug prices are artificially inflated in this country by Medicare and Washington cronies.

If I were a dictator, I'd mandate everyone who takes a salary must save some percentage (6-8%) of every paycheck in a personal medical savings account the way that Singapore does. If you get health services, you have to pay the full freight for the services out of your account, encouraging market forces. When that account runs out, you're screwed.

It's not taxed, and you can leave your account to your heirs. You can also buy catastrophic health insurance so you're not screwed in the event of a big event. The government offers low-income people additional catastrophic health insurance options and charities help pick up the rest of the slack.

We can't force that kind of mandatory savings in the US, it's unconstitutional. But, if we could go the mandatory MSA + catestrophic health insurance route, we would maximize market forces and yield results close to universal coverage that results-wise goes far beyond anything you can propose.

See? I've thought all about it.

I could just as easily say, "you have no realistic plans for controlling costs while delivering high quality service in abundance." But I suspect the life and death aspect of health care is an overriding priority for you, and delving into cost/waste/fraud/abuse is a non-starter. I believe that access to health-care in name only (a.k.a. government-induced rationing) is no health-care at all, though. Affordable, effective, abundant: pick 3.

So, no more insulting my intelligence, and please assume good faith, my friend!
Right, and if you're doing processing of ASCII code points (this is 95% of Markdown parsing, for example, the major exception being case folding and Unicode whitespace), then it's just as convenient to do those in UTF-8 as any other representation.

The fact that you need a prescription at all for many of these drugs is crazy.

I don't agree with drug laws related to addictive substances. But at least they make sense. Even laws related to antibiotics. There's potential for abuse, so the controllers at least have a logical (if not reasonable) argument.

But what possible purpose does it serve to require a prescription for insulin? Or chemo drugs which have no pleasant effect?

The blatant racket isn't even questioned when things like this happen.

We should be lobbying to remove the need for prescriptions from most drugs and to remove liability for drug sales from pharmacies and other third parties. This way, they don't have a say. And they shouldn't.

America is a place where the 0.1% probability there is a negative reaction means 25% of the population can't access medications. And they have the chutzpah to say it's for our own benefit. Legislative capture at it's worst.

In 2029? I don't mean to sound "apocalyptic", but currently we're on track with a lot of global warming projections, 2030-2052 is the 1.5deg temp projection (https://www.c2es.org/content/ipcc-1-5-degree-c-special-repor...). So by 2029 time we might be at 1.3 or 1.4.

I don't know much about other industries, but I do know what happens when there's a long and hot summer in where I live. The water shortage was so alarming in Manila this summer, so I expect water shortages in certain parts of the world to be more exaggerated than what happened this year. Any industry that deals to contain/service water/ice during heat waves will be raking in cash.

Jan Gray is, I think, more-or-less the Godfather of this approach. I especially enjoyed his Circuit Cellar 3-part series where he describes and builds the xr16 -- a 16-bit machine whose instruction set is designed to well-match the LUT capabilities of an FPGA. I implemented it, and with the LCC C compiler, I was able to run plenty of code.

Eh, that's not really the case anymore either. It's made many improvements over the years. Not that I'm saying it's some wonderful language, but you can't really compare it to the PHP 4/early 5 days. I think credit is deserved to the folks who have brought PHP to where it is today.
Yes - similar. Sometimes companies don’t have the courage to say No to bad revenue.

Decoy effect: The trick that makes you overspend
Yes the language server protocol is particularly insane because they use UTF-16 word positions (sort of, it's JavaScript so it's not anything standard really), but the actual text data is sent as UTF-8! So for my sane UTF-8 speaking language server the text gets converted from UTF-8 to UTF-16 when loaded from disk, then converted back for transmission via the LSP, then converted back to UTF-16 by my language server so I can handle the positions, and then it does everything in reverse again on the way back!

Absolute madness. I think they will fix it eventually though. The madness is too great to ignore.
> If you spend all your time trying to prove to strangers that you're hip to the latest trends, just how much time are you spending doing anything of actual value?

This is something I've wondered about a lot of social media users to be honest. I mean, if you're seeming spending all day on Twitter or what not, how are you finding the time to actually do any work? Do any of these super outgoing social media addicted conference every week developers actually have a full time job? Or is their entire career about promoting themselves?
I mean, the underlying code base is still PHP (granted the code base is awful) but there's a lot of Java spaghetti code out there too you know.
> At least now, if a cancer patient gets denied drugs, they can go to another doctor or get a second opinion.

This is not true; if your insurance company will not cover a specific drug then going to another doctor will make no difference. And you can’t go to another insurance company outside of open enrolment - assuming your employer even offers plans from more than one insurer.

There are other factors but just one is under discussion: cutting the bottom five percent in performance reviews. And if consecutively "meeting expectations" puts you near the bottom, then the expectation must actually be to exceed expectations.

Nevermind that this policy necessarily means churn and undervaluing aspects of software like security or fault tolerance and a constant drain of institutional knowledge.

Much of these can be done via EEG sensors.
This mapping of wavelength to RGB value is very misleading: in particular, when moving to higher and higher frequencies, blue does not wrap around to red creating purple. The perceptual color space that we are used to working in by mixing pigments or various frequencies of light is independent of light frequency. Unlike all other colors in the rainbow, there is no single frequency that will activate both the red and blue cones within your eye to create purple; if you had a single frequency between blue and red, it would look green. Instead, you must have two disjoint frequencies both stimulating the red and blue cones simultaneously (note that this is not strictly true, as for some people, the red cones do have some response down in the blue range, but the amount of red response within the blue region is extremely weak, and will not give the sensation of purple that is shown in articles such as this one).

This is why rainbows do not have purple at the edge, and why prisms do not create purple; it is a "non-physical" color (I made that term up, but it hopefully makes sense given my explanation above).

For a more physically-sound mapping of wavelength to color, see the CIE XYZ color system [1]. In particular, in Figure 2, the "pure wavelengths" are given as points along the outside edge of the curved surface, and as you can see, purple does not exist along that outside edge.

For those interested in simulation of color, I highly recommend Jiahao Chen's old notebook "The Colors of Chemistry" [2], which goes through a lot of these concepts, and accurately simulates things like the color of solutions just from knowing their chemical composition. Truly fascinating stuff.

This can be read in two different ways I guess, and ccsalvesens reply is a valid reply to the way I'd read your post, -namely that "Norway can neither make their own weapons nor their own planes".

You seem to have meant that Norway cannot develop both weapons && planes, true?
