Ask HN: What are you thankful for?
As the year is nearing its end, and Christmas markets have opened, people may be in a reflective mood.

I certainly had the opportunity for some reflection these days.

Everybody likes to groan about the health system. Long waiting times. Two-tier treatment of patients, based on whether they are privately or publically insured. Doctors in a hurry.

(I'm talking about my home, Germany, by the way)

But it isn't so bad, after all.

Yesterday late in the evening, through a combination of inattentiveness, tiredness and a kitchen knife, I happened to cut myself pretty bad (although no sinews or bones involved, at least). And I hadn't been able to still the bleeding, even after an hour.

I'm thankful that there is a telephone hotline giving you advice.

I'm thankful I could go to an Emergency Room where two highly-trained specialists (a trauma surgeon and a nurse) not only desinfected my wound, stopped the bleeding, and IV-administered antibiotics, but also made sure it would heal "good", probably with a scar, but not with any deformation or so.

I'm thankful I could get another highly-trained specialist (another trauma surgeon) to look at it today, on a Monday morning, without an appointment, and continue treatment after only waiting for three hours. Yes, waiting for hours sucks. But it doesn't suck nearly as much as not having him look at it.

I'm thankful they will take some more time over the next week to ensure the wound is healing properly and no infection is rotting the flesh.

I'm thankful I don't get a bill for all that. At all. You can say that I pay for it through incredibly high taxes, but it's relieving that I can actually plan my health costs. That they are predictable.

So, what are you thankful for?
Thanks, I'll add to the "prior work" section.
FB would not have allowed him to make Whatsapp. It was built with a philosophy of correctness ("We can never drop a message") and privacy. Contrast that to FB's "move fast and break things" and disregard for privacy to the point that they stole users' call logs right off their phones.

So there's no way they would have listened to Acton and let him build Messenger the way he wanted.

Add to that the fact that Acton's ideas didn't yet have any market validation. Once WhatsApp was a proven success, FB was willing to pay for it, but even so they are now destroying what made it good - https://www.theverge.com/2018/4/30/17304792/whatsapp-jan-kou...
I'm not sure the analysis front-end is really where the money is at. There are lots of industries that have trouble getting their data to a place where it can be analyzed at all. I know some very successful companies here in flyover country that picked a sector where this is a problem and made a business of fixing it.
No way. You don't miss out on 5G because you couldn't come up with $4B and your smaller competitor could. If it were $40B, sure.
This is interesting to me though, because if it's the case that a person without a permanent address can start making money through the gig economy, that's providing more equitable employment opportunities than what was available prior.

Not quite, at least from what Netflix has publically stated about its content strategy. Each time Netflix produces content, they view that content as having very diminished value for the customer that has already watched it, but that new content has made its subscription offering more value to the next potential customer. With this line of thinking, Netflix probably doesn't want you to every "finish" its catalog. I think there are exceptions given what Netflix paid to keep Friends. But, my guess says they found that most content does not get repeat viewership, which is much different than music for instance.

Seems to me more of a case where companies no longer train grads, and instead tell them to work on a proof of concept on solving a hard problem without paying for it, a sad state of affairs.

There is a small CS/AI community that works on "argumentation", putting exactly the problems you describe in symbols. For anyone who is interested in the details, there are several books on the topic, for example the "Handbook of Formal Argumentation" by Baroni et al. I concede that formal argumentation is--as far as I know--still waiting to be applied in large-scale scenarios.

More importantly, they were the first to bypass the democratic norms of the republic in order to get their agendas passed (by skipping senatorial approval for their bill, and censuring a tribune for vetoing it), and their opponents violated even more norms in order to halt their agendas (by passing an emergency decree calling for their deaths).

The saga of the Gracchi is when the cracks in the Republican order first began to appear. This pattern of norm-breaking back and forth between progressives and reactionaries would repeat until there were no norms left and it took six decades of civil war until peace and stability was restored by the imperial dictatorship.
What? The GoPros sold in the US will just be produced in a third country, the article doesn’t say where though. You can still get a Chinese made GoPro in China

The interesting bit is where GoPro will get the cameras for the US market produced.

If you're going to use cost-benefit, then you have to look at the margins. The delta cost is time out of your day. Learning issues, caring about outcomes etc., is just going to be done at the level that people do it going about their normal days (perhaps unfortunately). You read the news, you see outcomes, you have an opinion- then voting is a small additional effort.

Why? If your alphabet is [0-9] then it seems like your set is just the integers, and those are countably infinite. This case is even more restricted, where you only have two elements in the alphabet. So where does the continuum come in?
Tax cuts were sold to the American people as something that would bolster jobs. Clearly, that has not been the case (GM = 15k job cuts, Ford = upwards of 25k job cuts, Verizon = 10k job cuts).

It is not a weird lament; it is calling out the lies of trickle down economics.
Interesting approach!
All depends on your server and settings and network of course... But the mobile clients could probably do more uploads in parallel, like the desktop client does.

Just keep in mind it uploads the original files, not, like eg whatsapp, downsized, compressed one that is 1/10th the size...
"Analysis paralysis" is a real thing, so I partly agree with you. Sometimes you have to take parts of a large concept and "dick around" with it to discover the unknown unknowns and how not to do it, then feed that back into analysis.

After a number of iterations of this, you converge on a baseline architecture that you try to support future change without being excessively focused on YAGNI. Over-focus on YAGNI often leads to architectures that are so inflexible that when you DO need it, you can't add it without a demolition crew[1].

People should also remember the context in which YAGNI came up: Kent Beck, Ward Cunningham, Smalltalk, and the C3 project. This particular combination of people, project, and process made YAGNI feasible. And the C3 project, which spawned XP, was not as successful as folklore would have it[2].

It's not always so. Imagine if YAGNI was the focus of Roy Fielding and the HTTP specification, which has lasted remarkably well because of allowance for future change in the architecture.

Scrum and other processes that claim adherence to the Agile Manifesto work best in certain contexts, where code turnaround can be fast, mistakes do not take the company down and fixes can be redeployed quickly and easily, the requirements are not well-understood and change rapidly, and the architecture is not overly complex.

Many other projects don't fit this model, and people seem to think that so-called "Agile" (which even the creators of the Manifesto complain is not a noun), and mostly Scrum, is the sole exemplar of productivity.

The fact is that there are many hybrid development processes, described by Steve McConnell[3] long before the word "agile" became a synonym for "success", that may be more suitable to projects that have different dynamics.

An example of such a project could be one that does have well-defined requirements (e.g. implementing something based on an international standard) and will suffer from a pure "User Story" approach.

Let's be much more flexible about how we decide to develop, and accept that you need to tailor the approach to the nature of the project, based on risk factors, longevity, and other factors, and not on dogma.

And let's not underplay the extreme importance of a well-thought out architecture in all but the most trivial of projects.

> Battery life is only a few hours unfortunately because the circuit draws an enormous idle current of 23mA :o

This is because the device is silly. Firstly, there is an unnecessary voltage divider for generating a reference voltage. It is too stiff (resistors are too low-valued at 1K + 1K). This provides a reference voltage that is conveyed to high impedance destinations. 18V into 2Kohms means this consumes 9 milliamps!

Secondly, the device contains a bizarre circuit that tries to amplify the GND-GND path, using two op-amps in parallel.

The numbers check out: 9 mA for the voltage divider, plus around 8 mA x 2 IC-s (typical value from datasheet): 25 mA.

Here is how we can fix things.

1. We have two batteries! That is a true dual voltage supply! We can just take the center reference voltage between the two batteries. By doing that we lose the voltage divider entirely, and save 9mA of supply current.

2. We can lose the GND-GND amplifier, and just provide a proper end-to-end galvanic ground connection. We eliminate a pair of op-amps, and thus an entire IC chip.

We're now down to the current draw for a single NE5532.

3. Use a different op-amp. The NE5532 isn't great for driving low impedances like headphones. There are op-amps that are better suited for this, and draw less quiescent current.
The insane part is, if you are an American company trying to release a smart watch, you won't be able to get your cost of goods down that low.

I worked on the Microsoft Band team, the RAM inside the Band cost almost the same as these watches cost to make all up!

Annoyingly enough, when we asked MediaTek if we could buy use their chipset, they would only sell it to us with their OS running on top. IIRC I think they were softening up on this stance later on.

Suffice to say after paying for a Western company's MCU + the RAM, the cost was already way above what these watches cost to make, add in all the other parts and, well, that is how you end up with a $200 MSRP.

On the flip side, things like a custom made light pipe to improve HR accuracy are necessary to go from "good enough" to "best in class".

The other side is they hire a false positive, and suffer through the different sad state of affairs?

A lot of posts here make the leap to how decisions like this would work in the West. The contexts could not be more different. Until very, very recently China had pretty much no credit available to private citizens, and until the advent of WeChat a few years ago there wasn't much in the way of electronic funds transactions. And the Chinese have tended to be very, very good savers.

This all adds up to mountains of cash in private hands, especially held by older people in the middle class. The Chinese government and people value stability above all else. Eliminating cash just isn't going to be an option in the near term, even with a totalitarian government.

>and if you are a member of that group, and they paid X dollars to target that group with an attempt at disenfranchising them then we arrive at an estimated cost of $(X/population of group) to target you (among the others in the group as well).

Sure, but that doesn't imply they would have spent $(X/population of group) to stop you personally from voting, if it was not a part of a package deal.

>The emphasis on individual vs group only serves to distract, groups don't target individuals with disenfranchisement because it's just easier to target entire groups.

That's true, because our laws are set up that way. The important distinctio between group and individual is that you choose to vote or not vote as an individual. You don't choose to vote as a group. Voters are not suppressed as individuals. They're suppressed as a group.

>They still don't want you to vote

They don't care if you personally vote or don't vote. They care about how many people like you vote.

>then clearly your vote is worth both the concern and the price of the group targeting you (among other people).

No, it's not. What's worth something to that group is reducing the number of people in your category that vote.

>Vote, and preferably against the group of people that uses voter suppression as a tactic for winning an election in a democracy.

Out of spite? What if the policies of the people using voter suppression align better with your interests than do the policies of the people whose votes are being suppressed?
There are many forms of "news" out there (we're on a site called Hacker News after all :) ), which is probably what my complaint about that article would be.

To me, more specialized news sources sometimes definitely can be relevant to your career (think trade journals and similar), or perhaps helps you learn new things (techniques, tools, etc.) about your hobby. Definitely I've learned some things from these type of sources.

If you have a good local media source, you will also see stories with relevance to your life, perhaps affecting some of the things you do, at the least involving the town you live in. Unfortunately good local media can be tough to find in some places.

It usually does not involve me directly (though it indirectly involve me if said investigation is about things I pay for via taxes), but I do appreciate good investigative journalism sometimes for unearthing various wrongs and putting public pressure on organizations to do the right things. Good investigative journalism unfortunately is also in decline, however.

I think Aaron's point is absolutely correct when it comes to the current trend of "news" to be talking heads shouting at each other, and yellow journalism designed to titillate, not inform. Even more sober journalism can over-focus on national issues, and that can be problematic without a balance of the local, as Aaron IMHO correctly implies. Unfortunately increasingly national and increasingly overemotional is the most visible trend of "news" today.
Fear not, Thomas Bayes will rescue you!

> You cannot replace the European population with an African or Middle Eastern population and expect the same outcomes.

True. I don't. And I don't know why do you think a replacement is ... planned/wanted/desired!?

The population of Europe is hundreds of millions of people. The number of immigrants is currently 2 million a year (into the EU). (And without adequate integration and support systems that's obviously too high.) Current total immigrant population is 16 million (in the EU), so less than 1%.

> 30% overqualified for their current job.

That doesn't mean they are over-educated. Some are. Some aren't. How many are under-qualified?

Furthermore, do these folks with their fancy diplomas have higher incomes? If yes, why are they over-educated again?

I agree that education's quality is shit. But that doesn't mean that education is bad, or that we have too much of it. Maybe we need more of CFAR ( http://www.rationality.org/ ) and less useless-feeling schools. More self-learning ability and more time to exercise it and less organized lectures?

> America broadly shows that the low-tax route is better, [...]

Better? US social mobility is down in the gutter. ( http://www.oecd.org/els/soc/1-5%20generations.png ) Despite the low taxes. Why? Because the income inequality is growing. (Poor healthcare is just one thing, the enormous student loan problem makes the US education system very much a no-no. And US cities are rather far from sustainable, the CO2 footprint per capita is very high in the US.)

> Europe needs to make hard decisions

Agreed, but we need to make the smart choices.

The founders didn't like too much democracy for ALL SORTS of reasons, some valid and some not. They built a system that mostly empowered people like themselves. I'm not demonizing them, historical context matters and they did all sorts of stuff that was good and important -- my point is simply that we should feel more willing to question their assumptions than most people have been willing to do.
"Throw in many other things like the fact we've not detected life off-world,"

I do consider the simulation hypothesis to be one of the answers to the Fermi paradox, because "not deeply simulating the observable universe" is definitely another one of those obvious ways of cutting the load exponentially. Again, lots of attention to detail; if the external universe is something other than a full QM-level (or true ToE-level) simulation, it's obviously running on one heck of a detailed model... but it could still be exponentially less detailed than it superficially seems to be.

Of course, even if we are an island of advanced simulation, there could be others out there, surrounded by much-lower-detail areas.
What I have realized is that in such companies your importance to a company is only as much as the next project. When project agendas changes, next time might be your turn. So take it as a warning to find a better place soon as possible.
Yikes. A release in November introduced an API bug that was active for about 6 days, impacting 52.5 million users.

* With respect to this API, apps that requested permission to view profile information that a user had added to their Google+ profile—like their name, email address, occupation, age (full list here)—were granted permission to view profile information about that user even when set to not-public.

* In addition, apps with access to a user's Google+ profile data also had access to the profile data that had been shared with the consenting user by another Google+ user but that was not shared publicly.
Just a question on wording, but doesn't 70% imply currentRevenue * .7. Whereas they really mean 170% aka currentRevenue * 1.7?
Yeah, to improve the ROI we need to either make this extremely useful for users, or lower the cost for authors by automating the process or by making it really easy to markup content.

If you/investors are not satisfied with the current growth of the company but the company is profitable and not in danger of shutting down, it seems like it would be a wise move to invest the profits towards R&D to create some sort of product that may have better growth. You'd have the benefit of "infinite runway" for your next product and the investors have a chance at getting their money back.

That's definitely correct, $4 billion is meaningless. If it were $40b to corner 5G, Verizon and AT&T could come up with it and T-Mobile couldn't.

For significant business purposes, both Verizon and AT&T could borrow $40b easily. Whether for an acquisition or critical spectrum buy. They both have plenty of borrowing capacity despite being highly leveraged (it'll very likely end badly one day in the future).
