So if I understand correctly, unfolding one level would embed the referenced documents in the result one level down, two would also embed the documents referenced in the root document's referenced documents, etc.

I think it's definitely worth supporting differing depths of reference embedding along different paths. Ideally though you want want to select which properties are included as when you get to several levels of embedding the resulting document is very large and often you only need a subset of properties expanded for the embedded documents.

Additionally it can be very helpful to embed along reverse references (parent.children from the reference stored as child.parent.)

Concrete example, take this page on a scientific data portal: https://www.encodeproject.org/experiments/ENCSR807BGP/

The JSON-LD document representing that object itself is: https://www.encodeproject.org/experiments/ENCSR807BGP/?forma... and many reference paths are expanded to generate the JSON required to construct the UI: https://www.encodeproject.org/experiments/ENCSR807BGP/?forma... (this is larger than it needs be as the entire referenced document is embedded rather than just the necessary proeperties.)

While pre-generating the deeply embedded document means fetching it is fast, as the site has grown keeping them up to date becomes challenging so I've been looking at options for embedding dynamically.
In hard realtime systems, the problem is not "we have enough time to do the computation" but "we can prove the computation will run in the available time".

The complexity in modern mulit user operating systems (many processes, a run queue, spin locks) along with modern processors (multi tier memory architecture, micro-code, branch prediction, long stalls for memory access) mean it's very hard to prove that anything will run in finite time.
Do a lot of these asymptomatic people end up developing severe symptoms?

If so, what does that mean for herd immunity?
I don't know if we can count on the ACA staying around forever.
Most users will at the very least use two IP addresses - home broadband and mobile SIM broadband.

Then you have wifi hotspots, friends wifi. The average user uses many IP's and not limited to the range of one ISP.

SO whilst you can fingerprint devices and usage patterns, the IP address will by itself be useless to identify such users, it may well augment a little but is no solution.

But then IPv4 shares many IP addresses across mobile and broadband users in various ways. Most do not have a fixed IP and even those that do, do not have a fixed IP upon their mobile data activities - unless they VPN into their home broadband. Though if they use service VPN offerings, then another layer of IP ranges.

So the potential towards false assertions based upon an IP and user usage may well trip up and fail. Imagine using an ISP with dynamic IP and the next user of that IP uses it for crime, well with some bad logging and aggressive association, you can mislabel somebody for a crime they did not commit.

Roll on IPv6 and with that, mobile carriers would of been the obvious benefit of that, yet I'm not aware of any progressing that in any timely manner and chug along using a pool of IPv4 and various tricks to make those cater for many.
Very interesting, thanks for the link. In that case, how should that change our mental model? It seems like more people in Western countries are infected than visible, doesn't that mean the same would apply to China? How would it spread so fast in December?

"Have a real chance to be one of the biggest game changers"

Meanwhile the media response has been universally lamenting that a president would "tell people" [he didn't] to take this drug. How many outlets jumped on the single chloroquine phosphate overdose as proof of the president's responsibility? I encourage you to search "Trump" and "chloroquine" and find me a single headline that doesn't tear into Trump.

Like most people, your views have been warped by headlines and op-eds being touted as "news."

The fact that the president acts like a child doesn't mean our news should too. The petty editorialization of the daily briefings are an excellent example - the media's job in such a case is to be an objective first source - not to force their point of view through adversarial headlines that change every 5 seconds and "fact checking" only his alleged untruths. But this is where the majority of Americans get their news. It's shameful.

Edit: hell, look at this absolutely ridiculous headline at the top of the CNN "fact check" page: "Fact check: Trump denies saying another thing he said and makes more false claims at coronavirus briefing"

What kind of headline is that? Is anyone competent left at CNN? The media no longer deserves the soft power it wields. They lost that privilege when they strayed so far from any semblance of objectivity.

Absolutely, but there's more than one reason to buy a product, and people buying the cheapest and smallest model with last year's technology aren't generally the novelty-seeking "gotta have it" people. Especially people using an iPhone SE in 2020 and raving about how much they love the design. They're not going to win these people over with "new!"
I can personally discount everything he says, that doesn't make it any less legitimate to say that the President of the United States shouldn't hold press conferences in which he over-hypes the proven effectiveness of certain drugs during a pandemic.

Otherwise anyone can just claim anything whenever they want without any proof whatsoever.

Snatcher Is Cyberpunk Noir at Its Best (2017)
Most (not all) of the sites and YouTube channels that focus on affiliate marketing are not what I'd call 'high quality'.

They focus on pumping out shallow review after shallow review, with tons of cross-linking and spammy marketing techniques to get you to click on product links.

There are exceptions, but cutting the profit margin for sites that were set up to basically push people to click Amazon links may make the search results for 'product xyz reviews' a lot more helpful instead of being 50 or so shallow reviews, then a couple decent ones buried in the deeper pages.
This strikes me as a project that was created while drunk or high, probably high, possibly both.
It's frankly one of the reasons I got rid of my iPhone 6S shortly after buying it, for another Android phone. A lot of Apple's ergonomic choices just seemed bizarre to me compared to most Android devices. I'm sure they've gotten better since, but things like the fingerprint reader on the front were in my opinion bizarre and made me have to completely hold the phone different just for my fingerprint, where on most Android phones my finger is already right there in its normal usage position in my hand.

Sloppy compliance is the correct choice both here and generally

Oh my gosh. No.

There are countless examples of companies who have put a good faith effort into complying with laws and regulations only to have the gov't drop the hammer on them later.

And why not? Companies make good whipping boys for politicians and it's a relatively risk-free way to score political points.

Amazon isn't able to meet demand for medical or safety products. Or home workout equipment. The only video game systems are from price gouging third parties. They've only recently caught up on toilet paper.

I'm not sure why you think Amazon is somehow immune.
This feels like trying to fight a river. Help the environment by selling or trading in your old iPhone (and other devices too). Make sure they all get put through their full duty cycle.

Second hand and refurb devices are how Apple products become affordable to the masses like me. I can't justify shelling out $1k for a new phone but 1-2 years later I'll happily buy one used for $400.

What Is the Ideal Design Workflow for UX/UI Designers?
the quaker explanation is kind of wonderful, as i understand it. The main idea is that by making some speech Extra Special Truthful, I am corroding the trustworthiness of all of the rest of my speech. This is straight from the sermon on the mount, but you could appeal to the third commandment too. Willfully lying for your gain at the expense of others is one of the more corrosive things we can do to our community, so keeping it foremost in our minds as a thing to avoid seems like a real good idea to reinforce.

The other problem has an example from Tolkien: we are finite beings of imperfect knowledge, and if you swear an unbreakable oath, you stand a good chance of winding up like Fëanor and being forced to be a kinslayer against your own intention. Don't assume that much power, it's gonna bite you. This matters less in my neck of the woods than it used to, but there are certainly places still where blood feuds exist and nobody seems to know how to escape their trap.
Some of these lenses are quite amazing. My favorite lens from this class is the leica noctilux at f0.95. It is tac sharp even at f0.95 (if you can nail the focus) and the images make even an amateur like me look like a photo god.
Me too. iMessage is the one and only reason why I switched to an iPhone. My family demanded it, because the picture/video quality in our group chats was degraded for everyone because one group chat member (me) had an Android.

I got an SE. And now I'm seriously glancing at this new SE. Size is fine for me.
Iphone SE user here. Big screens is why I have an iPad in the house. Small form factor is why I have an iPhone SE in the pocket. My iPad gets _much_ more use than my iPhone. I'm not out and about much, even before the virus. I see phones sticking out of people's pockets and it makes no sense to me.
It was a multi-drug combination therapy without real control arm as far as I saw. Also the 95% confidence intervals were overlapping, and the probablity of the high dosage being more lethal is not published.

I actually think we can say for certain this is NOT a good representation of the general population. The general population has not been living in close quarters with multiple COVID positive people.

Ask HN: Get low tech skilled relative setup with a video call device?
We have a grandparent that is eager to be able to regularly video chat with us/our kids. I would love to just have something shipped to their house that will work out of the box with no/minimal setup. You can imagine with the isolation of Covid 19, and the fact they live alone, seeing us would be very meaningful to them.

We use FaceTime for other slightly more tech capable relatives. If it was setup out of the box, they could likely pickup a call. But I know setting up a new iPad or iPhone can be tough when you struggle to understand what WiFi even is! Ideally I’d ship them an already working device, perhaps the same way we would setup a kids iPad, with FaceTime, and ship it to them.

I wonder though if there’s another low hassle solution? Or other tech I should be looking at that nails this use case?

In more normal times I’d go to their house. They’re unfortunately a few hundred miles away...
> You're on ycombinator, the center of Bay Area tech culture

Citation needed. I think YC users think they are the center of tech (or the universe?).

What would be that actual proof that it was? Do we know how many users HN has? What % of VC actually spend time here? What % of meaningful founders actually spend time here? Ya the CEO of github will drop a post on a major thread concerning his company, but so what?

Honestly the more time I spend here the more I see two notable demographics: cynics trying to feel superior (like myself), and people trying to justify their own salary and lifestyles via a fat FANNG paycheck.

P.S. and college students / recent grads who know everything.
Pandas Pivot – The Ultimate Guide
Wrong (Trump Voice)
This is largely not the case anymore. Lots of democoders include their sources or put them on github. Plenty even do in depth write-ups on how they made it.

In particular, nearly all PC 4k coders are super active on shadertoy and most of their tricks appear there first, all in the open, before they roll a full-fledged 4k with it. It

And I dare say that in the past, the competitiveness as a reason for not sharing code was mainly a cheap excuse. The real reason was that everybody was ashamed of the terrible messes their codebases had inevitably become.
There are two stories here: One is whether one of the most promising drugs to stop the pandemic is actually dangerous, and the other is what Trump said and whether he was right to say it blah blah blah.

Thanks to the inclusion of Trump in this article by National Post, anyone who has strong views about Trump (most people in North America) are now focused on the second story, instead of the first.

I've always dreamed of leaving behind Silicon Valley and pursuing emergency medicine. I need to stay the course for a while to ensure my college approaching kids are taken care of but stories like this are inspiring reminders that age doesn't have to be a factor when I finally decide to make the move.
The thing you are missing is world governments want to milk this crisis, not act objectively. There is simply no other explanation.

They always were saying it wasn't magic bullet, but some people did not keep the context and started to spread only part of the story.
You're omitting the base rate.

The base rate probability for an arbitrary drug to treat a disease with no treatments is probably extremely low, < 1%. There are thousands of drugs; at most a few treat COVID-19. Suggesting that any single drug has a significant chance of a positive effect puts it well ahead of the pack.

By contrast, the base rate for a former Senator doing an okay job with the Presidency is probably in the range 20-80%. Suggesting that Biden would do as well as any other former Senator (may or may not) is not an endorsement, but suggesting he would do much better than the base rate is definitely an endorsement.
US is generally not testing people with mild symptoms to significant symptoms. We are mostly telling people to stay home until you have difficulty breathing.

That’s why are deaths to cases ratio is so high before the new infection rate has dropped to near zero for weeks. Adjusting for infection vs death curve in China US deaths from people currently infected are likely to hit in the ballpark of 50k to 100k. Assuming we get new infections under control in the next few days and keep it low for the next month.
Worked as a Frontend engineer. Now a hotel owner.

Few reasons why I left:

- Wanted to try something different.

- Incompetent management (Biggest reason), and politics at the workplaces.

- I am not good at expressing my self. Not good at kissing asses. Political correctness and all the stuff/

- Getting old (40)

- Single earner in the bay area with family. I couldn't afford a house in the area that I was living in. I didn't want to drive far for a job. I had the money for a downpayment, but paying $4000-6000 in a mortgage + taxes seems scary. I end up buying a rental property.

- The majority of the family is in the east coast.

So far, no regrets. I am not sure how this COVID-19 will affect the future.

I love writing frontend code (don't like react or other frameworks). Whenever I am bored/feeling down, I write code. I write my own utilities that I needed to get stuff done for my business. I was using JS for theming in one of my 5 years old PWA. Yesterday, I updated to CSS variables.

After all, technology is the future. Not sure any better place then hacker news.

This is not at all true of the IDE pair (Visual Studio / XCode) I use at work.

I do all my code editing in spacemacs and use the IDEs as heavyweight build / debug / code-search frontends (not for lack of trying to do these things in emacs, mind you). The process of doing each of those things is completely different between XCode and VS.

The Cost of Waiting to Contain the Pandemic
> it's theoretically possible to linearize a random write workload

In fact OSes have been doing this for years now. Over a decade. There is a drawback however. To make this work you need to buffer your writes in a cache, typically in volatile memory, so they can be sorted before being written to the drive. The larger the cache the more improvement you see (although there are diminishing returns on this), but also the more data you lose in the event of power loss or kernel crash. So it is a tradeoff between speed and resilience.

Interesting thought about how this changes for SSDs. While you don't have seek times to consider anymore, if you have two writes that happen to fall on the same block in the SSD it is a big win to combine them, so SSDs still want to buffer data and have to make the speed/resilience tradeoff.
Huh, I hadn't seen that! That's really neat, and a possible real solution. Any product links? Doesn't need to be an endorsement, just as an example.

Edit: Oh, but then I totally forgot in this whole discussion—if it's Bluetooth I'll also have to remember to charge my damn things! Bleh. Still would like to see an example though!
This is hilarious! I was excited hoping that it was a fuse file system that let you mount a view of another file system with regex though, something that would be a pretty useful tool.

This particular article is not bad on that front. For example:

[Folks, the point is not about Trump here. The point is that the article's author clearly knows that CQ and HCQ are separate but related drugs].
Emirates Conducts Rapid Covid-19 Tests Before Boarding
I'm so sorry for your loss. This hit especially close to home because my grandmother has been suffering from degenerative mental disease for the last few years. I don't live in the same country as her anymore and every time I return, it's horrifying to witness just how fast a person loses their sense of "self".

I think degenerative mental disease like the one here is especially traumatizing since to most of the world, you're physically/visually still the same person. Also, the characteristics that formed your personality often morph into these harrowing alternations - in the case of my grandma - she was always immensely active and always on her feet. She now cannot sit for more than 30 seconds at a time and attempts to run away from home (with no particular destination in mind). She was (it feels strange to write past tense here) a great cook but now she enters the kitchen and has no idea what she's cooking or what step she is on. It is extremely difficult to keep her mind at ease at all. Her mind is so unable to focus or string thoughts together that she has resolved to loud abject shouting of gibberish (much like a toddler) since she has no idea how to convey what or how she got somewhere. But then for the briefest of moments she has complete lucid clarity and will ask me about my job and life, and offer to cook me my favorite dish.

Much like Lee's wife, I don't really know when my grandma's last "real" day was and what my next trip is going to bring sadly. It's a sad and slow torment.
I feel like HN forgot about that particular guideline a long time ago.
Apple’s upcoming ARM laptops and the beginning of the end of x86
>Well hydroxychoroquine is only useful before ventilators are needed (it attacks the full lungs) and is actually detrimental - we know that - after by its nature.

I’m worried that this has totally left the realm of science and is just pure politics... there is no evidence for a ‘magic window’ for HCQ in COVID-19 treatment, or any solid evidence of a positive role.

Secondly, having supplemental oxygen is not the same as being on a ventilator. I imagine most hospitalized COVID patients need oxygen (otherwise, they could be managed at home).

I hope we all avoid making comments (or even accepting comments) about medicine without either critical, independent study or background knowledge.
