it's impossible to approach the edge of the universe too, despite that border having a physical location.

No, it doesn't. There is no edge to the universe. Our best current model is that the universe is spatially finite, but even if it turns out to be spatially finite, it is unbounded--the spatially finite model is a 3-sphere; like the surface of the Earth but with one more dimension. The surface of the Earth is finite, but it has no edge; a spatially finite universe would be the same way but with one more dimension.

Seen from the outside it is infinite.

No, it isn't. Seen from the outside, the hole has a finite mass in a finite volume, so its density is finite. (The finite volume an outside observer would assign, based on the surface area of the hole's horizon, is not the "actual" volume of the hole; but it works well enough as an "effective volume", the volume that the hole occupies from the standpoint of the rest of the universe.) The singularity can be viewed as infinitely dense, but the singularity does not occupy the entire black hole; it only occupies the center at r = 0.
Apple And Microsoft Completely Disagree About The Future Of Personal Computing
It's not surprising that you manages to justify abuse of power, people in power always do.
the real answer is also generally:

"do minimum at work, you don't need to actually do more than that"

it frees your brain to work on the side stuff. its not just time that is needed. many of us keep working and thinking about work even when they're not technically "at work", for hours. Or the "i really should have this finished".

Nope, you don't.
>I've been much more at peace about it. Not all the way (yet?)

I've been a Christian for 25 years. I don't think you'll ever be completely at peace with your mortality--in the same way that riding a roller coaster is still scary even though you know it's safe.

But I've seen the difference in the way my Christian and non-Christian friends handle death, and the difference is striking.
If you're posting to Hacker News, we can probably assume you're above the average level of computer usage. Maybe for you it seems like "one click," but for grandma and her new laptop, would it be?
College is when you transition from the (hopefully) "happy place" you were as a kid to "the real world".

It sucks that Yale didn't help this person when she need it. But it certainly doesn't get any better in the real world.

If, one fine afternoon, your boss says "how are you?" and you say "I cut myself earlier today", then expect to be promptly escorted out of the building. Perhaps to a mental health facility, if you're lucky.

If, one fine afternoon, your boss says "how are you?" and you don't say "fine", be prepared to explain yourself in detail. You'd better have a way with words, because your job is definitely on the line. Especially at a startup.

You might say "that sucks". And it does suck. But that's just the way it is for 99% (wild made up number) of the jobs in the USA. Unlike grade school soccer games, your employer isn't going to hand out trophies just for participation.

All IMO of course.
given the black hole mass large enough, the gravitational force at the Schwarzschild radius can be as small as we'd like it to be

No, it can't; the "acceleration due to gravity", which is the acceleration required to "hover" at a constant altitude above the horizon, diverges as the horizon is approached.

What can be made as small as desired by making the hole's mass large enough is tidal gravity at the horizon.

several billions years ago, when observable Universe had 10B radius, it would be a black hole

No, it wouldn't. A black hole is a stationary spacetime. The spacetime of the universe is not stationary. The spacetime model that describes the universe is very different from the spacetime model that describes a black hole; the fact that you can plug the mass of the observable universe into the Schwarzschild radius formula and get a number out does not mean that number has any physical meaning for the universe.
Wow, I'm reminded of the saying "be careful what you wish for, because you might just get it" (i.e. at the expense of everything else).

You just might be successful in your startup, but what is that worth if there is nothing else in your life, and no one to share it with?
> In theory you are right. In reality, you run a huge risk of triggering a bigger problem if the patient have a sexual abuse history.

Depending on the intake procedure, that can be part of the 'flowchart' to deal with.
5 work days = 120h

How is cutting off a depressed person from the positive factors in their life (future, friends, studies, activities) considered taking care of the patient?

Wouldn't you imagine that blowing the floor out from under an elite college student with friends and interests and a future and sending them to a dead-end, alone, in their parents house would make things a great deal worse? If I were considering suicide even with all those positive things in my life, there'd be no consideration necessary when they were taken away.

Instead, the knowledge that this could happen just provides pretty damn compelling reason not to seek therapy or even support from friends.
If signals cannot cross the event, how would I not notice my missing feet?

If your feet are below the horizon and your head is above it, then you must be falling through the horizon; it's impossible to remain at a constant altitude at the horizon, even for an instant. So a signal emitted by your foot would still reach your head; but by the time it reaches your head, your head will have fallen below the horizon.
>Especially at a startup.

Disagree†. High turnover is not desirable anywhere, but it is far less tolerable at a startup. People are far less interchangeable and systems are more often bound up in people's minds rather than in some employee handbook.

†Depending what phase of startup you are referring to, a somewhat tangential discussion.

A room temperature superconductor may have been found
(Please correct me if that's wrong.)

It's wrong. Time dilation is not something you observe yourself to experience; it's something another observer observes you to be experiencing. "Time" is relative, so you can feel your own time to be ticking away perfectly normally while it appears to be ticking much more slowly to someone else.

As your feet approach the event horizon, the tingling will get slower and slower, because time passes much faster for your head than for your feet.

No, this is not correct. As you fall toward and through the horizon, signals travel between your head and your feet just fine, and you don't notice any difference in how fast they travel. But, as I posted upthread, if your foot emits a signal towards your head when it's below the horizon and your head is above it, then by the time the signal reaches your head, your head will have fallen below the horizon.
ah! thanks. :)

>“Well the truth is,” he says, “we don’t necessarily think you’ll be safer at home. But we just can’t gave you here.”

That quote was the central piece of the article, and why she had formed the thesis you're talking about. If get mental health issues, you will be kicked out of the school. I disagree with you that this taking care of the patient.
I find the whole "schema-less" thing to be a side-effect of NoSQL marketed as a feature. Unless you are about prototyping a small feature quickly (which MongoDB is great for) - on the large scale of things, 5,6 months out in development time, you will find that the time saved on "not having to do migrations" may very will be nil. In most cases, if you want to keep your hair you end up having a schema anyways. At the very best MongoDB and friends make it easy add columns, but removing and changing datatypes might as well be migrations. Also, as the article mentions, Postgres now has a JSON data type making the schema less advantage kind of useless.

When it comes to limits of relational databases some of the real limits are actually sharding, replication and high availability, which are all relatively more difficult to do on the popular YesSQL databases.

In any case, its pretty tiring to see NoSQL only refer to MongoDB and other document stores. Redis, Cassandra, HBase and Hive are all NoSQL engines ranked before the next document store, and IMO have a lot harsher performance penalties for incorrect usage than Postgres & friends. Given that Cassandra is a the second highest ranked NoSQL store which also (sort-of) enforces a schema, implying that the limits on relational databases are schemas is pretty bizarre.

Not precisely. You get restrained to ensure that you will cause no self harm or harm to others. Some of it is harsher than perhaps is warrented for the 'lightweight' case, but the procedures have to deal with very difficult individuals who have cut the hawser to the land of rationality.

You can find the laws for each state listed online. Some of the laws for mental health management and confinement are very reasonable. Others, less so. And there is no blessing that means laws are followed all the time.

I am personally surprised at the level of restraint in this particular case, but I do not know (1) the standard procedures in this hospital and (2) the amount of other issues going on at this particular point in time.

I am also surprised that the author was essentially tossed out and not given a medical withdrawal.

However, the author may have left out bits of her story that would explain these aspects and provided the full context.
The event horizon isn't the surface of the black hole. As classically defined, the event horizon is the point at which the black hole's gravity becomes inescapable.

But the horizon isn't a point; it is in fact a surface (a 3-surface in 4-dimensional spacetime). Whether you want to call that the "surface" of the black hole is a matter of terminology; the hole is not a solid object--it's not really an "object" at all in the ordinary sense of the term, so it doesn't have a "surface" in the ordinary sense of the term.

Congratulations on your recent entrepreneurship! I owned an ISP in the 90s and PAID an answering service to answer calls after office hours. Two of us would carry the dreaded pager (one of the first SMS devices out) and we'd coordinate who would get the call. I'd take the 2AM calls usually - being the owner and all. A strange thing occurred over time.

A few of the ladies at the answering service started doing simple tech support for the customers. Reboot your modem/computer/check your password. Said they were bored and it was interesting and didn't mind. Ended up giving them accounts for free. The call volume was noticeably lower after that. A few hours without doing dialup tech support is like a slice of heaven.

I feel like this is sorta like that. You can answer a few of the more common questions, maybe get your users to fill out details (maybe a standard form that prints to a handout for the guests even) and use those to populate your agents screens when a call comes in. Stuff outside the scope of the info you gathered gets kicked to the user. They don't get a completely free vacation time, but it's better than it was. Don't promise it'll be 100% interruption free. That means you need to change your marketing a bit, but it's still kinda cool what your offering

Best of luck! Pools of knowledge are going to be big.
Ahh very cool. I'll have to add support for this to ihmage.com
lol, Microsoft need to learn how to write Android app, especially in Java programming
Say that your leg is inside the black hole, but the rest of you isn't.

This can only be true for a very short time; if your leg is inside the horizon, you must be falling through it (if you're not, your body is being torn apart). So your leg can send a signal to your head just fine; by the time it reaches your head, your head will have fallen through the horizon. Similar remarks apply to atoms, chemical bonds, etc.
An angle grinder and/or drill can do wonders. If you can snip the cable, you can remove the lock head at your leisure later.

This still slows down the casual / opportunistic thief markedly, of course.

from the point of view of the human, it takes infinite time to reach the event horizon

No, it doesn't. The proper time (time by the infalling observer's clock) that it takes to fall to the horizon is finite.

their speed will approach the speed of light

This isn't correct either. The infaller will see the horizon pass him at the speed of light, but that's because the horizon is a lightlike surface--it is moving outward at the speed of light.

There are ZERO emotions in Merrit's comment. I understand you are upset about this, but really Merrit isn't the bad guy. You should think about why and try to not blame others for how you feel about it. This type of behavior isn't healthy for any of us.

I believe it's illegal for the school to share that information with parents, provided the student is an adult and hasn't given consent.
Well, people love a good disagreement, don't they?

Do I think that people should learn self-defense because they could be victims of violent crime? That's one reason to do so, yes. As women tend to be a particularly vulnerable subset of "people", this applies to them in particular.

What does it matter if this scenario was not that of a particular type of violent crime? I don't see where you're going with the mugging comparison. Violent crime is violent crime.

That I didn't immediately chastise the aggressor doesn't mean that I don't blame the aggressor, but the fact is (and I've said this in another comment) if you cannot defend yourself, you are at the mercy of forces beyond your control. This is not a life philosophy or a political position, but a piece of advice based on fact of reality. Call it "victim blaming" if you want to (and I know that you do), I call it living in the real world.

If I'm caught in a mugging, it isn't necessarily my fault (even if I could have taken steps to prevent such a situation) and I probably didn't choose to get mugged, but that doesn't mean I shouldn't have some sort of self-defense plan in-place to mitigate risk.

This isn't about right and wrong. This is about surviving in a world that many of us forget is still very often hostile to our existence.

That is another element of possible reform, yes. I've watched the changes of the past 14 years with increasing gloom.

I also saw the effects of the liberalization of immigration regulations in the 1960s which saw floods of foreign students, many Indian, Chinese, African, and others, which had profound influences on US academic institutions, the communities around them, and, to be honest, on their home countries, one of which was a brain drain.

On that last point: one of the arguments for increased global wealth and/or population is that it would increase the number of geniuses and intellectuals (along with the rest of the population, one might suppose). That's possibly true, but I strongly suspect that the existing mechanisms for recognizing and promoting talent have already encroached on much of those possible gains. Not all, but a considerable fraction. Which means that the additional benefit would be smaller than a naive estimate would suggest.
Framed For Selling Crack, Surveillance Video Helps Him Sue Police
For what it's worth, I had that almost exact conversation, as an engineer at a startup. The only difference from what I wrote and real life was that it wasn't my boss, it was my boss's boss, the VP of Engineering, doing something called "management by wandering around".

That was 30 years ago, but I doubt that today's managers are any different. I did keep my job, but alarm bells were definitely ringing in top management that day.

Successful startups (which ours turned out to be) are often as much about risk management as anything else. Having employees that aren't 100% "fine", for any reason, is a risk. Of course that risk must be weighted against the turnover of replacing that employee.
Actually I think the problem are the developers that don't take the time to properly learn it.

This account is very disturbing. Her mental health "treatment" is illegal in the UK and should result in compensation payouts.

Don't Americans have anti-discrimination laws? And the decision to exclide people who disclose self harm is baffling, because people who self harm usually avoid seeking treatment. Not just avoid seeking treatment for self harm, but avoid seeking treatment for other stuff because they are worried about the self harm being discovered.

The author of this article (Paul) appears to ignore the law of large numbers - while Paul's arguments against using the figures from Backblaze as measures of drive reliability would hold if Backblaze's analysis was based on a small sample size, because their sample size is relatively large, Paul's criticisms don't hold. Paul's argument is that any analysis of hard-drive reliability should control for factors like vibration and temperature as these vary in all environments - but in fact, because Backblaze has taken large (enough) sample of drives, these variations are already controlled for (ie cancelled out). Sure the consumer is probably never going to experience a failure irrespective of whether the buy a seagate or WD drive - but that's not the point - the point is that the long tail of the distribution, WD and Fujitsu beat Seagate for reliability. That is still valuable information for people, even if they aren't going to be using their drives in the same type of environment as Backblaze.

I'm going to repost my comment here from a previous thread.

One of my jobs is an iOS Freelance Developer, and this path is what got me my first client.

It seems like you are very aware of what you are capable of. It's great to be realistic, but also realize that you are now in the professional market like everyone else. Like the other posts say here, NETWORK.

Go to local meetups and present yourself as a real professional. Create business cards (BONUS: Make yours stand out from the rest). You will receive many business cards by going to these meetups. You can probably gauge what would make yours flashier.

Here's an example of my business card that has been one of the most effective marketing strategies I've ever used: http://i.imgur.com/4LeH2vf.png

Update your LinkedIn, Twitter, HackerNews, Blog, etc immediately with solid and presentable information. If you're unsure of how to do this professionally, check out other professionals' pages and emulate success.

Now, BUILD THAT PORTFOLIO. Even one side project is generally enough to show someone that you can do the work. Do you want to show off your skills, but you're not sure what to build? Take a popular site and build a small client for it. This is one of the most exciting experiences you will ever go through. We hear about people building businesses all of the time, and it seems amazing. There is so much more passion - in my experience - when you are building yourself.

Please feel free to contact me if you have any basic questions about the whole freelancing process. I'm happy to help in any way! (Email in profile)
