Alright, I will withdraw my criticism of MySQL on this issue.

However....

> In 20+ years of DB work, I have NEVER seen anyone use UNKNOWN.

I mean, I've already shown where Microsoft does just that [0]. Oracle pretty clearly does the same [1] [2]. People don't use it because you can almost never refer to it directly. The language intentionally hides it. About the only place I know that you can is PostgreSQL [3], which supports the "boolean_expression IS UNKNOWN" predicate.

> The standard also asserts

I assume you've got the 2003 draft standard that's around [4]. I will use that because I don't see any more recent version of 9075-2 that's freely available.

Yes, the standard does say under 4.5 Boolean types:

> This specification does not make a distinction between the null value of the boolean data type and the truth value Unknown that is the result of an SQL <predicate>, <search condition>, or <boolean value expression>; they may be used interchangeably to mean exactly the same thing.

However, that's in the context of describing the Boolean user data type, a.k.a., BOOLEAN. You can tell because 4.2 describes character strings (CHAR, VARCHAR, etc), 4.3 describes binary strings, 4.4 describes the numeric data type, 4.6 describes DATETIME, and 4.7 describes user-defined types.

The standard is not saying that UNKNOWN and NULL are the same. It's saying that the Boolean user data type can use NULL to represent UNKNOWN. It's saying that if you choose implement a BOOLEAN user data type, you can use NULL to represent UNKNOWN. If you choose to assign a boolean expression to a column, that is. Nevertheless, an SQL <predicate>, <search condition>, or <boolean value expression> has a value of True, False, or Unknown. This shown by looking at 6.34 <boolean value expression>:

<truth value> ::=
TRUE
| FALSE
| UNKNOWN

Or by searching section 8 and seeing where every time they talk about one of the value expressions being the null value, then the predicate "is Unknown".

Ohio's first self-driving shuttle service begins on December 10th
Free will is a lie the mind tells itself to cope with reality.

No matter where the choice to act rests, it's not with the individual willing it to be so.

In a western society, with ample choice and the ability to make those choices, one might feel like they have free will. Look elsewhere, and you'll see that the "choice" to act is very limited to the circumstances of your life.

Perhaps there's no choice, but there's an examination/consideration of the alternatives. We mistake this examination as a choice process, even though we only have one choice (the one we end up making).
Dragon Resupply Mission (CRS-16)
You've got lots of good advice here, but much of it seems rather boring, and you seem like someone searching for the fire within.

So, here you go:

Step 1) Forget you have any money at all.

Step 2) Withdraw $5000 in cash and buy a plane ticket to Pattaya. Bring only a backpack. Get a room for $15 a night. Budget about $15 a day for food, $10 a day for a motorbike, and perhaps another $20 discretionary. Your total burn rate is $60 day. One more thing -- leave your computer at home. Now that you're a multimillionaire, you can actually afford this.

Step 3) Live your life. Find things that attract you or repulse you, and make decisions around that. Maybe you hate Pattaya! No problem, take the train north to Chiang Mai, or if you feel like a true hippy, try Pai. Keep a journal if you want. Send emails from hostels, and crash there if you need.

You'll return with a new appreciation for yourself, and the world around you, and material things like a shiny new car, or a mcmansion will seem a lot more boring.
Why Mastodon is defying the ‘critical mass’
Doctor's are notorious for not understanding their patients' experiences, and how that impacts them.

I've just witnessed this with my partner's recent bout with cancer. While her oncological surgeon completely understands, her reconstructive surgeon had no conception of what she was going through.
I can't see how an average Tumblr user is aware of Mastodon.
I have a hard time understanding how people disbelieving in free will do not just devolve to fatalism. Why bother discussing it as if it matters, when it's all predetermined? Why do people having the argument seem to assume in their lives that free will exists, exhibited by their pursuit of their wants?
Try out Notion. Works great on all my devices (MacBook, Chromebook, Android). Free tier is quite generous.

I really like that in Notion you can just spin up quick data tables with rich data objects underneath.

Those people spent many years learning to understand, diagnose, and treat thousands of medical issues. During that entire time, they were continuously sleep deprived as a matter of culture. Those that could not handle this environment dropped out. They're probably still sleep deprived. They may have learned about sleep's medical effects, but the personal experience of those who survived the selection process who work 120-hour weeks and have been waking patients up once an hour for years has a blinding effect on this diagnosis.

It's a bit like bringing someone from south Florida to northern Michigan this winter for some ice fishing. I understand that it's cold here, I intellectually know about, have observed the effects of, and can treat frostbite and other problems resulting from this cold - but all that would make it hard for me to intuit the problems of a visitor who was unable to control their fingers when they removed their gloves and dipped their hands into a minnow bucket to bait a hook. My fingers work fine in that bucket, everyone else on the lake is doing it, you're just going to dry them off in a few seconds and put them back in warm gloves...what's the issue?

Yes. Any notification causes vibration, wakes up the watch to show the notification (or if the watch is in use, show it as a small overlay), from which one can read the content and take actions, including replying straight from the watch.

I always have the watch on silent, so no notification tone. I have no Samsung apps short of the Gear app and Samsung Health.

I think they know exactly what they bought. They are going to see if they can change Tumblr. If that succeeds, great! If not, shut it down.

I bet the price of Yahoo including Tumblr and the price of Yahoo excluding Tumblr was more or less the same number.
Yes, yes, and no. Definitely get some (objective) professional money management help. Pick someone the wealthy use like JPMorgan Chase. Take care of your family; buy them houses, cars, and education. Find a charity you care about and don't just give money but get involved. And use some of it to help another startup get started.

OP called them both "stocks" and "money" seemingly interchangeably. (I don't recall the title showing "all cash" when I replied but maybe it did.) If it's actually in cash, you're totally right of course. Some people treat vested and released shares as if they were cash and look at the balance (shares times last trade), call it "money", and start making plans based on that.

TL;DR it’s not the same thing, but a lot of people do feel cars are a problem.
My girlfriend is a second-year OB/GYN resident (which is a 4 year program) and while that field's residency is less insane than some other specialties like ER, she still works 12 hour shifts Mon-Fri (6a-6p on paper but generally 6-7:30), one 24-hour weekend shift a month, and one 12-hour weekend free clinic shift a month. This is on top of the "extras" that are not work but are required to graduate the residency programs. Weekly rotating presentations to the rest of her group (4 other second-year residents so one ~45 minute presentation every 4 weeks), research, generally keeping up with the state of the art in her field, etc.

So she's only "scheduled" for ~67 hours a week averaged throughout the month, but realistically it is in the 85-90 range.

It's easy to see how a more demanding or emergent field could seriously select for folks who are more able or willing to work on less sleep.
"Works on a shift schedule" is a shared trait between nurses and shift workers. "Has one thing in common with" is not the same as "is the same thing as".
From what I can tell, they won't actually be driving most of the time.
They likely would get picked by super elite research orgs like IAS, or work outside the system and get grants from people like Simons.

Or have a low level teaching job like that guy who proved a twin primes result a few years aago.
You should go. The more people who can afford such a luxury should take advantage, because as their business scales up the price will come down, making it available to more women.
once hooks are in, I think React Context will be a lot more usable. Right now, its composability isn't great because you have to use nested render props because it's not very HoC friendly.

React Context makes a lot of sense though, because you'll effectively be able to create your own Redux nested at any level in the DOM. This means local state will be much easier to manage and you won't have the issue of having to stuff all your disparate contextual data into one shared store.
I'll tell you one thing: I really don't appreciate an article that just continually asserts investors are idiots. High end retail! They're stupider than Saudis!

I'm sympathetic to the idea that Uber has lots of headwind. As mentioned, the majority of costs scale with revenue in a way that isn't true of real tech companies and the autonomous driving thing is basically dead. But there's lots of reasons companies could fail - it's not enough to list them.

One glaring hole I see in this analysis is the monopoly view. Uber is establishing itself as a monopoly in some markets and pulling out of the ones that it's failing to achieve that. A pretty straight forward step would be to start jacking up prices in areas they have a monopoly whilst simultaneously driving out the competition. That would be profitable and it addresses the problem the article proposes.
Is that actually the case?
> Free will is needed to identify who the criminal is in any given situation, ie. who are the morally responsible parties.

Belief in free will is required (in most common ethical systems at least - there were whole religions believing in deterministic salvation, where God made people who will sin and can't do anything about it - and people carried on, punishing crimes as usual :) - instead of striving to be good to deserve the salvation people were supposed to strive to be good to prove they are these that will be saved).

Existence of free will isn't.

In universe without free will there can be people who believe in free will and "decide" who is criminal based on that. It's their brains causing them to do so, but in reality neither they, nor the criminals make any decisions - it's all predetermined. But everything still works the same way, and their consciousnesses feel in control.

BTW even the common moral systems doesn't always care about responsibility - for example if you steal because you're a drug addict - nobody searches for the first guy that gave you the drugs and got you addicted. It's assumed it's impossible to find, and to keep society functioning they put you in jail (even if you had no choice).
Anecdote time. I spent ~3 weeks in the hospital with pneumonia in 6th grade (age 11 or so). For some reason the time they decided on to give me a daily dose of antibiotics was 3am. They were pills, so I had to be woken up enough to swallow them. Fortunately my mom wouldn't stand for that shit and put up a fuss and it only lasted a week. I was in bad shape, I was in the hospital after all, but not such bad shape that antibiotics were so urgent that they were worth ruining the sleep of a sick child on a nightly basis.

I really like Vue.js for SPAs. I come from a Node/Php/Go back-end. Vue was the second front-end framework/library I learned, the first being Angular 1. Vue is way more intuitive. If you have experience with JS its really easy to get rolling. If you have no JS experience, just remember typing is a myth and you'll be fine ;). They also have a few examples on their website.

So, my partner had the option of either going home directly after surgery or spending the night in the hospital. The hospital staff wanted her to go home. She wanted to stay. (She has issues with post-surgical pain.)

If the hospital staff had sent her home, she would not be woken every two hours. The medical staff were fine with that.

It would have been perfectly reasonable for them to let her sleep; it would have been no more risk than they were advocating for.

Clearly it was optional.
>Free will is needed to identify who the criminal is in any given situation,

No. Causality is all you need to identify who the criminal is.

Physical stimuli are basically all we need as intelligent beings to come to a conclusion about things we don't like happening to us, and thus ultimately make into moral laws or codified ones. These are the inputs, these are the causes. Then, once enough human beings have had those inputs result in a large enough collective coming to the conclusion that stuff is Bad, we end up with laws.

Then, whenever someone acts in a way that we have determined is Bad, they are the criminal. They do not need to possess free will for the rational thing to do to be to provide punishment for them, because punishing them ultimately changes the inputs used by others to reach decisions. Nothing about this requires free will - it's all just as applicable if you just believe the laws of physics and causality determine every choice we make.
Real life IDs can be forged/bought, multiples can be forged to verify others. There is no technical barrier to attacks on this sort of system, only financial barriers.
If you were to view people as a composition of their choices, then in the current branch every individual chose said branch. Every person who did not chose the current branch, is now a different individual.

If the universe is considered a set of individuals or object, then it's unclear whether a multiple paths could lead to equivalent universes or the same. It all depends on the category theory (is the composition of choices associative, etc).

That being said, I really don't like multiple/branching universes theories.
AlphaZero made choices in chess, and learned from them. So did I get you right: it had a free-will because it is a necessity for this behavior according to you? Because mere "machines" can't make decisions, and can't learn from consequences.

I've had some of the best lucid dreams I've ever had while my sleep was disrupted by living in the second story of a building smack dab in the corner of a very busy street corner during broad daylight. I had a night job so my sleep schedule was from 7am to 3pm. All in all I had half a dozen lucid dreams and one mindblowingly extreme out-of-body experience which left me breathless upon waking. I think I even had a night terror or two while I was there.

I didn't hate it. Sleeping during the day has taught me how to put a pillow over my head in order to block out all light, and now I can sleep in the brightest loudest room without trouble.

I haven't had lucid dreams since then, or if I have, they've been really really rare and extremely hard to remember. Now that I think about it... Could my lucid dreams and OOB have been triggered by smog from the traffic in that area??
> How many Western governments are trying to draw legitimacy from ancient Rome or Greece?

Overtly, very few if any. But look at the education curricula of the US--you get a large dose of Roman and Greek history. Discussion of the structure of US government literally drew parallels to the structure of the Roman Republic and Athenian democracy. Our government structures are designed in edifice to be replicas of the ruins of Rome of Athens. Even our math curriculum is derived from Greek mathematicians.

Where the difference exists is that Western countries do not claim to be an unbroken continuation from ancient Rome and Greece as China does.

> Can you think of a comparable piece of Latin or Greek writing that the average Westerner knows by heart?

The New Testament of the Christian Bible, which was written around the height of the Roman Empire after all, certainly before the Tang and Song dynasties you mention. Most people have probably read the Odyssey or the Iliad at some point (and definitely can relate the basic plots of these books). Writings of Plato are also pretty likely to be well-known to most people, but most especially philosophers. And I hear that doctors have to recite a famous passage from Hippocrates as part of their studies...
