I may have missed it, but in many scenarios, the reason p95 etc matters isn't that it is 5% of cases ('of course 3g users are slow') but each user may issue many requests. Ex: If serving 20 assets over a session, most users will be hit w a great p50 and bad p95.

Trouble shootong at the session-of-indiv-requests level is tough, so being able to zoom in/out is the power of correlation IDs and observability stacks (vs this kind of monitoring view afaict).
Well, for one thing, if people can be tested to confirm they had and recovered from the virus and therefore have some immunity to it, those people can more safely assist people who are currently ill and move about more freely in society (unless they are still at risk to transmit the virus to others, of course).
Pope nailed in with Obra Dinn in how he implemented the detective gameplay and story telling. The game had me with several wtf story moments. This is one of those games that I'm reluctant to start playing as I don't want it to end to soon but can't stop playing once I've started it.

Also worth watching are these insights into the game design (and a chance to enjoy the soundtrack again) (spoiler warning): https://www.youtube.com/watch?v=OMi6xgdSbMA https://www.youtube.com/watch?v=V0qxLrFycrc

> And RFID would just have replaced bar codes, so no process changes necessary for a first implementation.

There would have been changes necessary. RFID chips fall as electronics under RoHS and probably regional/national recycling regulation which means that their introduction into products would cause an enormous overhead. Additionally chips cost at least 10ct each in bulk which means for a lot of 1m units you would lose at least 100k $ in profit (or offer the product for more money, which is ... difficult to do when dealing e.g. with Walmart).

The only way RFID could have taken off would have been if governments mandated their usage.
When I first got an iPad I was almost certain this was going to herald a great resurgence of point-and-click style adventure games. I still don't really understand why it didn't. Unwillingness to pay for software I suppose?

The interaction is perfect for a touch screen, the display is amazing, and the casual demographic seems like the ideal one to pick it up. Even puzzle games, like Phoenix Wright, would have worked well. It's really a shame that stuff like Candy Crush ended up dominating the space instead. There are some bright spots, like "The Room" or some Professor Layton games, but they're few in number.
South Korea is far from the only place COVID-19 is present, and most of the rest of the world tests barely anyone, even if they have symptoms and would like a test, either due to lack of resources or formal policies of only testing hospitalised cases. I can detect my infection, but statistics on the rate it is spreading in the UK can't.

It's also pretty well established that even in symptomatic cases where testing is widespread the disease has a multi-day incubation period.

That isn't what I took from it; it sounds like various components (the example given was CPU and GPU) can sort of "trade" energy budgets:

> send any unused power from the CPU to the GPU so it can squeeze out a few more pixels

What it sounded like to me (also a layman) is that they have a fixed energy budget that's tied to the thermal properties of a baseline unit in a neutral environment. As long as they're under that budget, they can boost up the clocks of individual components that are under load. So heavy-rendering cycles can use relatively more GPU and heavy-compute cycles can use relatively more CPU.

That might be totally wrong, though, and I would also appreciate an expert's explanation.
Careful. Remember, it only counts as a case if it's detected, and South Korea-style contact tracing is a lot less capable of detecting small clusters that have split off from each other due to the people tying them together no longer testing positive than they are large clusters involving the same people going to the same church or office with attendance-tracking on a regular basis.
Agreed. Official information has been "Herd Immunity", "Masks don't work", "the risk to Americans is low", "the only effective treatment is rest."

And on and on. Twitter has done a huge service to correct these awful experts.
It was an historical reason. WSL1 was named such because instead of using Linux kernel, Microsoft uses Windows NT subsystem to run Linux userland (hence Windows Subsystem for Linux). As WSL become a well known name, the next iteration (the one with the real Linux kernel) is simply named as WSL2.

Similar. 37 yo. I loved NES, Sega, and SNES. I really enjoyed Doom. Later, half life and a couple counterstrike mods. Heros of might and magic, StarCraft 1 and 2.

Nowadays, nothing perks my interest really. I did really enjoy Breath of the Wild and Ori and the Blind Forest. Everything else is just kinda meh.

I have scarce time. Something has to be really worth it to take away from family time, home projects, chores, work, professional development, working out, and hobbies (reef aquarium, banjo, audio books, and smaller interests like ATV, bows and guns, and emergency prep).

Not sure about global shipping concerns, but I do think that 30 years of companies optimizing for Just In Time delivery in order to avoid the risks of excess inventory has made us prone to shortage crisis when 'excess' inventory is needed.

Its pretty clear at this point that the shareholder value revolution has been a disaster for many people and the planet.

Who knows. Maybe this is a fluke maybe not. When you notice a correlation you study it. Sometimes you discover it isn't significant and stop further study. Sometimes it is significant so you study more.

That isn't to say your question is bad, just that it could be years before we understand.
Amazon has outages all the time, hidden on their status board with a green triangle, and you still lose S3 objects once you’re operating at a large enough scale.

A quick google search for “amazon outages” lists the numerous extended outages they’ve experienced.
Interesting backstory, but the article doesn't actually provide a reason. It just states ifconfig has a bug, and "I do not fully understand they did not just update ifconfig(8)".
Ah , yeah, I see how the title could be understood that way.

In my experience, it's not that companies are choosing any one strategy over another. It's more that companies have no idea what their supply chain actually looks like. Only that the widgets show up at their loading dock every week, and that the shipments have always been reliable in the past, so that there's no reason to look any further.

There are often strong disincentives, as well. Nike, for example, got themselves into trouble when parts of their supply chain became public. Many more companies regard their unique supply chain as a competitive advantage. So, even if you should take up the time, effort, and expense to research your own supply chain, there's a high likelihood that your upstream vendors will have no interest in sharing their suppliers with you.

There are exceptions to this. Reportedly Apple has excellent supply chain visibility, but they've achieved it at great effort.

(I'm by no means an expert, but I used to work for sourcemap.com, an MIT startup based around the idea of understanding supply chains end-to-end.)
To cloud or not to cloud is the same as any outsourcing decision.

For many operations, you may get to a point where it makes sense to build your own cloud.

If you're a seller, you might also get to a point where you want to sell goods directly.

It partly depends on your core expertise, meaning, is this part of how your business creates value? If NASA doesn't want be a datacenter provider, they should continue to outsource it.

It also depends on whether their business model aligns with yours. AWS's egress rules specifically work when you are getting revenue from the data being downloaded. If you're selling software or other media, and you can factor the cost of downloads into the price of it, pay-for-egress is very sustainable.

Other models like pay-for-capacity don't align as well if you want to maintain a large library of media and people are attracted by the variety, but only download the popular stuff.

For NASA, pay-for-egress may be entirely justified if their budget is based on usage of the data. Or if they can simply use "requester pays" to mitigate the cost.
You can't misuse an ORM pattern and then call it bad for performance reasons.

Same thing is true for SQL.

I'm currently working on migrating a 10 year old asp dot net c# system of applications. The amount of nasty stored procedures being called from other stored procedures that call on multiple views and total disregard for data modeling best practices is atrocious. I've had to just throw away shit code and get the business requirements in order to completely redo the SQL queries because they were impossible to read and fix.

We had a single query with over 2000 execution plans due to parameter explosions! It confuses the shit out of the database query planner and caused intermittent performance issues based on who ran the query with what parameters and when they did it.

His code example with m*n run-time is a total misunderstanding of how to use an ORM and is common among people who are used to thinking of databases as dummy stores. In reality, a database run-time can provide great performance when used correctly. Data partitioning, query optimization, materialized views, are all great skills to have in your toolbox. Most developers don't know jack about databases, data-modeling, and performance optimizations.

Active Record is fantastic for CRUD operations, it removes boilerplate code, and still provides good ways to join relational objects. Always select only the fields you need in ORM queries to reduce overhead and the data retrieved. Tune your database (rebuild indices, and partition your data properly). There's a general disregard for understanding technology and hacking of business logic in the service layer which results in poor performing applications. Perhaps that's what makes people hate on Rails and Active Record. It makes it easy to write bad, non-performant code. What works today on your small dataset, will not work 6 months or 5 years from now.

A tool is only as good as the person using it.

Don't be a fanboy hating on specific technologies, when you don't know when to use what for a particular use-case.

_Two_ possible deaths, if/when we get to the point that hospital systems are overwhelmed. "Under-50s survive when they get dedicated medical care and full access to medications/ventilators/etc they might need" is a _very_ different picture from "Under-50s survive without adequate medical care".

I am fine with throttling these services, hospitals and research should be given top priority, followed by all remote workers (or general traffic if that's hard to distinguish). These massive leisure services should be at the very bottom of priority.

Nothing! That happens all the time.

True fact #1: all bodies are different.

True fact #3: even if some people have no problem with caffeine and sleep, many do. The author acknowledges being sensitive to caffeine.
You're forgetting the development of a vaccine. With enough time (10 years is way more than enough), a vaccine will be developed and deployed, and that capacity won't be needed because far fewer people will contract the disease and develop symptoms requiring hospitalization.

The problem is, developing and testing a vaccine takes some time. How much time do we have before the global economy totally collapses?
In re: "Black Swans" the articles says:

> But over the past decade, we have had a number of black swan events.

which links to this: https://sloanreview.mit.edu/article/the-science-of-managing-...

> To a risk manager, “black swan” phenomena are highly unlikely events that have massive impacts on a business or society on the rare occasions they occur.

But the whole point of the "Black Swans" is that they are both unpredictable and we forget about or rationalize them away after the fact.

https://en.wikipedia.org/wiki/Black_swan_theory

Pandemics aren't unpredictable. This virus isn't a black swan it's just a large white swan.

If we manage to cope with it well enough to keep things more-or-less stable and then forget about it then it's a black swan.

- - - -

We could and should know better. You watch Star Trek and they're always beaming down to random planets in their shirt-sleeves, no space suits. Meanwhile, in the real world, we are expanding our "attack surface" (there are more of these viruses out there, as we invade more wild areas we will encounter more viruses) while weakening our systemic defenses (cheap international travel, extended supply chains).
> This is true of financial companies too. For example, banks that are run to survive rare events like global pandemic or world war cannot compete with banks that ignore the possibility of such events during normal times.

The opposite can't be allowed to continue. Spending heaps on stock buybacks to then months later be completely out of cash.

> Take McDonald’s. With $21.1 billion in revenue last year, it ended 2019 with only $898.5 million in cash on its balance sheet, a little more than two weeks’ worth of sales. Considering that the fast-food chain, which owns more than 2,600 stores, franchises 36,000 more and employs 205,000 people, generated $5.7 billion in free cash flow last year, it could have as much cash as it wants. Instead, McDonalds’ bought back $4.9 billion worth of stock in 2019 and paid another $3.6 billion for its dividend, almost exactly the $3.24 billion the company borrowed last year.

This is a joke. It borrowed 3.2 billion to pay a 3.6 billion dividend? And now it's CEO is meeting directly with the president to argue how enforcing paid sick time off due to coronavirus is a bad idea because it will hurt businesses too much. The system is so broken there are barely words.

Hi HN – I'm one of the authors of this proposal. I'd like to clarify a few points here:

* Wikipedia is not becoming an SPA

* Wikipedia is not dropping support for non-js users

* This proposal is not about changing our current browser-support matrix[1] (which includes IE11 as a first-class target; Vue.js ecosystem still supports IE 11)

* This proposal is about changing the way we develop enhanced, JS-only features across our projects; many such features exist already, but they are written in jQuery and an in-house framework called OOUI

* These features will continue to be delivered in a progressively-enhanced way on top of the PHP-rendered baseline for the forseeable future. We are interested in how server-side rendering of JS components can integrate with this but we're still looking into how this might work

* We will continue to prioritize accessibility, internationalization, and performance in everything we ship

I don't think that Vue is "better" than React, but I think it has some features which are especially helpful in our progressive-enhancement, ES5 (for now, anyway) use-case. But it's great to have so many amazing tools to choose from.

Previously we've been using a framework we created in-house for complex JS features, but it's a product of an earlier era of the web and is increasingly out of step with the current paradigms in UI development. We think that one big benefit of moving in this direction is lowering barriers to contribution (both for new developers at the foundation, as well as folks in the wider community).

Getting up early and going for a run before breakfast 5x/week solved insomnia for me. I changed from a night owl to a morning person almost immediately. It's been years now with no regression.
So, if a kernel bug happens in some interface, the only way of not being affected by that bug is actually deciding to not use that interface. Bugs become features, and "do not ever break userspace" causes cruft to accumulate.

The Lockout: Why Uber Drivers in NYC Are Sleeping in Their Cars
I had intense insomnia when I was younger. The points the author laid out helped me immensely - particularly limiting sleep. Specifically, I limited sleep to 7 hours a night, in bed at 10 and up at 5 no matter what. Additionally, as soon as got out of bed I exercised for 45 minutes. As the author mentioned the first couple weeks were brutal, exercising at 5 in the morning on 2 hours of sleep is not fun. After a couple months it stopped being so painful, and after 6 months I fall asleep in 1-2 minutes. I don't have children which I imagine would make this much more difficult. I also have a consistent work schedule which helps as well.
Same, started doing frontend back in the CSS Zen Garden days, and CSS-in-JS has been a godsend. Having the tooling do static analysis on your components and their corresponding styles has made life so much easier. Reference a color that doesn't exist? Error. Reference a component that doesn't exist? Error. etc...

Also, in response to GP: CSS-in-JS does not take away the ability to roll out global CSS changes without updating individual components. It actually gives you more tools to easily share styling across components.

Cardiogram cofounder here. I had a fever back in January and my sleeping heart rate spiked during those nights. It was interesting to see such a big change, so we decided to build a new Sleep BPM feature & annotation tools around it. Hopefully this helps users out there become more aware of how your body responds to the flu or other illnesses like covid-19, and how your heart rate responds to flu-like symptoms. One important note though - these features are not intended for diagnostics! Would love to hear if the feature is helpful - ask me anything!
