> It means that you generally don't have to special case the empty list case, you can just run let it happily do nothing.

The consequence of "if (True)" is usually to do something, not nothing. The consequence of doing something by overlooking the "empty list" special case may be harmful.

Preventing potential harm is more important than not having the programmer jump through a couple of extra hoops to account for the special case. That makes the special case impossible to overlook.

This kind of reasoning is generally accepted when talking about implicitly nullable types vs explicitly nullable types (optional types), but somehow in this context people are more stubborn.
Recently upgraded from my 2015 15 inch MBP to the new 16 inch MBP (32 gigs of ram). Overall it big upgrade - the higher resolution and bigger screen are awesome, and my XCode builds are compiling faster. That being said, I hate the touchbar for a few reasons
- Having to look at the keyboard to change volume is not an upgrade in user experience
- The touchbar freezes for me once a week or so and I have to go to the command line to kill the process
- The icons don't make any sense - (xcode dustcan anyone)?

Also, maybe its because I am a rock climber and my skin gets roughed up, but the finger print sensor has never worked for me on any apple products and its a waste of space. All and all though, the faster computer and bigger screen is worth it for me.
So why are different ethnicities of humans not considered sub-species?

They developed in different geographic regions with barriers, the can interbreed successfully, and they have different appearances, not just in skin color, but in things like facial features. And yet the article specifically states that humans don't have subspecies.

ty for tracking down the source. truly a great comment.
Volume adjustment is actually a great example of why I hate the touchbar.

- I can't adjust the volume without looking at it. Because the touchbar is flat with no haptic feedback when I land on a button, it's hard to remember the exact position of the volume 'button' without looking. Sounds trivial - but combined with point 2....

- The way the volume control expands - it actually moves the 'volume down' button AWAY from your finger, which again requires me to keep looking at the control.

This means that when a loud song comes on, it can take 2-3 seconds to quickly turn the volume down in total. I could do that with one single keypress in half a second or less on a keyboard, without needing to look at the keyboard.

That can also be the difference between missing a key detail from a quiet speaker on a Hangout.

Flashy, but it's a terrible user experience by every metric other than looks, I guess.
i dont appose the sentiment but i appose the statement of this being a illogical decission.
lets assume that unit of loss to tesla is 1 , loss associated with virus affecting customers and employees -> 5 . loss associated with virus shuting down production indefinitely -> 30 , loss associated with authorites suing you for breaking the law 0.3 . probability of the factory being shut down by authorities -> 0.8 , probability of your employees and customers getting affected -> 0.7 and probability of authorities suing you for breaking the order is 0.5 . so in total (30x0.8) > (5x0.7 + 0.5x0.3) . we might disagree in the scale and probabilities but the conclusion that this was a illogical decission is not direct.
My small regional health insurer here in the US has offered a couple different remote appointment options for several years now. It doesn't replace regular checkups, but it is very convenient when traveling, or for minor concerns.
If you let the corporation go bankrupt, the shares become worthless. But the assets remain, and can be taken over by new owners, who can keep producing airplanes etc.

At least that's the bankruptcy theory. Real world bankruptcy may well have a lot more friction.

Feel free to educate me on how the real world works here!
The difference is that Java bytecode is fundamentally insecure. Wasm seems to take inspiration from the research that went into NaCl/pNaCl.
Interesting idea moving the reception of messages to other nodes and getting back smaller set of messages. Not only that but distributing the reception responsibility into relay groups where it can be load balanced among peers.

The leader using relay nodes reminds me of how humans organize into boss and worker groups and the boss shouts out orders to group leaders.

I would like to see how dynamic relay groups will perform under stress and I wonder who would communicate new relay groups. Choice of leader imposing relay group structure or groups self organizing.

Ask HN: Are there other ways to filter search results by date
I have run into an issue lately that date range filters no longer work correctly.

For example, if you search "It's a common misconception that Bitcoin is a safe haven" it will return this result, and list it as 6 days old. https://news.ycombinator.com/item?id=22558517

If you change the search scope to "the last month" the result disappears. Adding site:news.ycombinator.com does not help.

Duckduckgo and Bing both exhibit the same symptom. Yandex does not even return a result for the search.

So you'd happily do away with web browsers and use shell apps instead.

rtv is still a hosted app; it's hosted in a command-line interface with command-line rules instead of an HTML-rendering interface with w3c standardized rules. Take away the shell, and rtv won't run any more than a web page "runs" without a browser to interpret it. But these things aren't quite so different as one may imagine (the capability set of one is much broader; the compatibility set of the other is probably much broader).
Are there any links with examples of their propaganda? I would like to be able to spot it on my forums.
> I see no problem loaning the airlines money.

A cynic would say if the airlines want market-rate loans, they can get them from the market.

If the airlines want subsidised loans, that's just a grant with a stick-on moustache.
I think Darwin was closer to Newton than Democritus in terms of knowing what the Hell he was talking about.

But, yes, your point stands: Evolutionary biology has moved on, and people who try to poke holes in a 19th Century version in order to discredit the whole field are misinformed and, likely, doing it with a partisan, rather than an academic, intent.
Seems like a pretty useful gadget to have, unfortunately the price is a deal breaker for me.
As soon as this virus broke out in China, I immediately remembered comments on HN from ~6 months re: open borders and mass population migration. I argued that robust border controls would be useful for preventing disease transmission and was criticized as connecting totally undocumented migrants to disease was "vile rhetoric". After all, "no one was suggesting restricting tourism to prevent disease."

Now here we are with a no-shit virus outbreak and neither the Canadians nor the Mexicans are interested in having Americans freely flowing across their border.[1]

I'd want to laugh at how the real world tends to shred the fantastical political/social positions of so many people....if it weren't all so tragic. :(

Thanks for the information. I agree that home microwaves heat unevenly but I think that is one of the reasons that the authors in the article went with bagging the masks. The steam would be trapped in the bags and the masks would get treatment at a more consistent temperature making the process more effective at killing the pathogens.

I think that microwaving the masks accomplishes the task using tools that an ordinary person may already have on hand and tools which require almost no training. UV sterilization is complicated by the need to avoid exposure to UV light and the fact that most people don't have a suitable UV lamp available. Hospitals may already have those tools on hand and in that case they probably have trained users who can disinfect masks with them. That seems to be the best way for them to reuse masks.
It's true that not all of the value is destroyed, but it is still very inefficient compared to a well functioning business. Whether it's less efficient than bailing folks out is I think an open question. Maybe with a case-by-case answer.
Tungsten, mainly. Anti-counterfeit testing now includes ringing the purportedly gold coin like a bell, if it passes the density test. A clad-tungsten counterfeit will have a duller, less sonorous sound.

This is where all those hours of listening to drummers drone on and on about the metallurgical qualities of cymbal brass--and the audible differences between Paiste, Sabian, and Zildjian--can come in handy.
If your point is "a variety of opinion can exist everywhere" then sure but that's not great evidence that nations aren't an "approximate proxy for values". If it's 90-10 in one country and 10-90 in another it's clearly a proxy and not a great argument.

Recently read it. The first part of how Pixar came to be was really really interesting. From his days in research to Lucas Arts/Film to Jobs. The rest was also a good read. I also recommend it.

I couldn't find any weight specifications for the Magic Keyboard for iPad Pro. For reference: the 12.9-inch Smart Keyboard Folio, without a trackpad and without scissor switches, weighs 407 grams. So, lets speculate the new keyboard, as a blind guess, weighs 500 grams. Adding this to the new iPad 12.9"'s weight of 642 grams, the total weight is over 1.2 kilograms, which already is in the range of the new MBA2020 with 1.29 kilograms. Why not take the full laptop instead, then?
I don't disagree. It would take a concerted shared will in an industry that still views, perhaps rightly, platform lock-in as a competitive advantage. Open source initiatives are great, but I feel that they're weaker than a bigcorp (benevolent?) dictatorship would be at picking a direction and moving in it.

When the headline comes out that DirectX13 will be a layer on top of Vulkan, then maybe it's a sign that the world is ready :)
But then you need soap... which might be as tricky to procure as toilet paper these days. And for good reasons. Without it, disinfection ain't really happening.
Shame, really. Not even a viable option for personal use.
I’d advocate for the opposite: VB is never going to get first class support. It was clear that I should jump ship when first learning it back in 2010.

Microsoft should just kill it (aka put it into mature support) and give clear guidance that developers should move on.

If you can learn and understand VB.NET you can learn and understand C#. It’s time to rip the band aid off.

But in any case, the supply chains of companies that use overseas materials have been disrupted. With effort, they could probably switch to using materials from a domestic manufacturer, but those manufacturers may not have the capacity to satisfy the increased demand. Per the OP, it seems like the limiting factor in production is melt-blown fabric.
I think it's more than that. Web applications run atop a user-agent-enforced security model that has been bought with decades of educational experiences.

Building one's own native app that direct-binds to the networking layer, passes user credentials around without the paid-for-in-blood browser API, etc., is going to re-invent the wheel on a lot of security problems that browsers had to solve (and history has shown developers love to ignore given the opportunity). It isn't just whether the web app will be a better user experience; it's also whether the app will allow, say, exploits delivered via the server-side state (introduced to your web app via user-modifiable content on your site) to sniff the user's password out of the pastebuffer or some such nonsense.
The Real Pandemic
I think this is the answer. If they want additional runway, they should dilute. It's fine for the government to act as a buyer of last resort in the event that it believes the market is responding irrationally. But it should still get a steep discount. The government can sell the assets back into the market when it believes the situation has stabilized.
I dunno, we expect people to be honest in every other aspect of their life. Why shouldn't marketers be honest too?

OK, explain European Early Modern Humans and Neanderthals being different species.
I'm European (I'm sorry I did not say that in my previous comment, because it can be misunderstood without that data). Europe is being hit harder now and we're part of the world too, why then not focusing on building ventilators for Europe so the US and other parts of the world will have more? Logically, you will prefer to work helping your own country, or even your own local community. That's normal and, in my opinion, the right thing to do.

However, since this is a global problem, I think there may be initiatives with which an engineer can help that are not focused in a particular region. I'm interested in those and, in particular, those that could directly help here.

I already got some good suggestions, so thank you for all the responses!
Anatomy of My Kubernetes Cluster
Ah right, the Iris model goes with the CPU model

"Configurable to 1.2GHz quad-core Intel Core i7, Turbo Boost up to 3.8GHz, with 8MB L3 cache" and "3733MHz LPDDR4X onboard memory"

so it's probably one of these:

>Firstly, judging a web browser’s compelxity by judging the spec catalogue is already unfair. The catalogue is basically a dump of things related to the web, for example the specs of JSON-LD. (Which probably has almost no relationship to implementing web browsers, since that’s just a data format of JSON.)

https://paste.sr.ht/~sircmpwn/13c1951014a256e9f551296a129bf6...

Specs like JSON-LD are included but do not meaningfully change the numbers. Also, the word count I used in the article is less than half of the real word count I ended up with, just to put to rest any doubts like these about the margin of error.

>Also, word count doesn’t correlate with complexity. That’s like…. saying that a movie will be more entertaining than another one because it’s runtime is longer. Web-related specs are much, much more detailed than POSIX-specs because of their cross-platform nature: we’ve already seen what happens if web-related specs look like POSIX: anybody remember trying to make web pages that work both in IE, Safari, Firefox in the early 2000s? (Or, just try to make a shell script that works on both macOS, FreeBSD, Ubuntu, and Fedora without trying out on all four OSes. Can you make one with confidence?)

This doesn't seem right at all. How do you figure that POSIX is less specified than the web? Have you read either standard?

Can you make a website with confidence which works on all browsers? When was the last time you found a browser-specific issue? Mine was three days ago.
Completely agree. I think people are too hung up on the "falsifiability" term and don't look at the bigger picture

As your link puts nicely: "John, when people thought the earth was flat, they were wrong. When people thought the earth was spherical, they were wrong.

The last bundle of financial bailouts included the Government taking an equity position in companies. They made profit when they sold the stock. One example is the ownership stake they took in Citigroup.

https://projects.propublica.org/bailout/

>The main sources of that revenue are $23.1 billion through dividend or interest payments, $19.7 billion from sales of equity or other assets that Treasury acquired (mostly stock in Citigroup); and $9.63 billion through stock warrants which Treasury received as part of most of the investments. When companies pay back the TARP investment, the warrants are either sold back to the company or auctioned off.

That's absolutely true as well, and in my reply above I wasn't contesting that, just contemplating what the poster above that mentioned about p hacking, how maybe this mindset makes it easier as a justification?

Yes. Gold has become (or always was?) as much a speculative asset as pretty much anything else. It's difficult to find a safe haven asset in any crash, because there are so many feedback loops and non-obvious relationships. Ex post we see of course many asset managers come out of the woodwork beating their drum on how their expertise allowed them to buy the safe haven asset that happened to work in a crash. This is survivorship bias at it's clearest.

After 2008, central banks managed to stop every single market stress with a firehose of money. Eventually this became an actual trade. Every single selloff was bought heavily by traders because of the near-certainty that CBs will provide a hard backstop to the panic.

Until last week, where a new regime is starting emerge perhaps where CB tools have suddenly stopped working, at least short term. Perhaps once the selloff stops, the massive money supply support will re-accelerate the buying, but right now we are in uncharted territory. The current market behavior is unprecedented. We saw the 3rd biggest one day loss in the entire history of S&P 500. Intraday volatility is through the roof.
