The original context is more nuanced. The quote was responding to "Can you have product market fit without monetization?"

> It depends your product. My definition of product-market fit is: you are drowning in demand—your product is being used by so many customers that you cannot handle all the new people knocking at your door!

> Absent that you do not have product market fit. Most people use the term too loosely.

It's easy to sell a dollar for 90 cents and be "drowning in demand". The answer seems to indicate that demand is a pre-requisite, but not necessarily sufficient.
Is it possible to get a "black bar" on HN to honor this god of physics, who contributed so much to the literature and inspired many people, including myself?
Most people have nothing to contribute to the world. Should we kill them off early?
I wish I had the words, and know that I won’t. But there was a time when A Brief History made me feel a little less alone in those socially awkward years, and I’m eternally indebted for that.

Im truly gut wrenched hearing about this. Such an inspirational person. Thank you God for giving us Hawking
Again, there are 2 equally valid explanations.

One is to say that the government want to protect people against themselves, to make sure they can withstand significant financial losses.

Another explanation is that those who match these conditions (I'd guess about 2% of the population) have successfully lobbied the government to maintain their advantage against the remaining 98%.

I do not understand why people downvote when I just say out loud the less palatable alternatives views. It seems to me we are not considering all the possibilities there.
Out of the 1000+ users, has anyone written an honest review? I'd be interested in hearing what people have to say. Does this work? Any side effects?
For a second I just couldn't believe this was real. Stephen Hawking was one of those people that inspired me towards a career in science, as well as a pursuit of discovering what mysteries of the universe I could uncover within my (cosmically short) lifetime. He did this not through some major life-altering speech I heard from him (although his talks and lectures were quite interesting), or through some grand quote that I read online, but rather through the fact that he carried with him the enthusiasm that comes with looking up, seeing a vast universe looming all around us, and finding that inner spirit--that inner sense of wonder--that drives us forward in an attempt to make sense of it all. Rest in peace Stephen Hawking; you will be missed.
“What do Sheldon Cooper and a black hole have in common?” Hawking asked the fictional Caltech physicist whose IQ comfortably outstrips his social skills.

After a pause, the answer came: “They both suck.”

Stephen's sense of humor has always cracked me up.
His life had surely been a bright spot in the brief history of our times.

Rest in peace Mr.Hawking.
I think the crux of the complaint of is the imprecision in saying e.g. "P(z_k | x_k) - this is the probability that we measured z_k, given that the true object is at x_k"

Technically, you can only give a useful answer about the probability density of the random variable Z_k at the value z_k, conditioned on X_k = x_k. In the Bayesian interpretation of the Kalman filter, you never have an event "I measured z_k" (that event has probability 0, of course).

I agree that the probability notation is the issue here. Look at how wikipedia shows Bayes' rule for continuous random variables on both sides of the |. : https://en.wikipedia.org/wiki/Bayes%27_theorem#Random_variab... That's the kind of explicit and precise notation I would use to help someone understand the Kalman filter from a Bayesian perspective.

Once you use that definition of Bayes' rule, then you can substitute the definitions of the multivariate normal pdf, Do The Math, and derive the Kalman filter recursive updates.
There's an old joke about American military doctrine:

The Soviets: "One of the serious problems in planning against American doctrine is that the Americans do not read their manuals nor do they feel any obligation to follow their doctrine."

The Nazis: "The reason that the American army does so well in wartime, is that war is chaos and the American army practices chaos on a daily basis."

America: "If we don't know what we are doing, the enemy certainly can't anticipate our future actions!"
Perhaps so, but that's not a crime. There's nothing illegal about trading on your own private research.

I'm really impressed you had this reference in mind. Did that event personally impact you or did you read it contemporaneously?

"None were arrested because the crowd was so large and because the number of matches exceeded the police's expectations.

'We thought we were ready to use it, but getting through the crowd and the architecture of the stadium proved overwhelming,' Detective Todd said."
I actually agree with a lot of this. If I thought that 15 random wild-west fantasists could pull of a coup, I'd see more of an issue with the right to own guns.

But the point isn't that when the government comes for me in particular, I can stop them. It's that when the government does something so horrific that the citizenry as a whole decides to do something, they can. Local, ad-hoc militias across the country could definitely get the job done.

Back in 1965, Stanislaw Lem wrote in his Cyberiad about a sadistic king who was given a virtual world to rule over. The king gleefully proceeded to torture its virtual inhabitants. Lem has a lot to say on the ethics of this.

He definitely feels like he warrants a black bar. Like maybe for a week... I mean its Stephen Hawking.
I agree. I'm tearing up a bit looking at the news. He was always a legend in my eyes.

He came to symbolize the power of human mind and in a broader sense, modern science. Humanity has lost a great mind today.
So the problem is kauffj alleging a ThinkPad T not working with Linux. Plain and simple, there is no such thing. Further, their description of said laptop has the wrong name (T540 vs T540p) and the wrong CPU very strongly indicating their laptop is not a ThinkPad T after all but something else. What else, I can't even guess.

This merited a strong reply because contrary to this allegation, the rule of thumb is to recommend a ThinkPad T or X for someone looking a Linux laptop.

You can accuse an old Porsche 911 SD of having problems with the front engine but people will be quick to point out that a) Porsche 911 only had an SC and not an SD version b) the Porsche 911 engine is in the back.

I think the point about unconscious states was not that you "become no one", but rather that it is an interruption to the continuity of consciousness.

As a thought experiment, imagine you were magically replicated during sleep such that, at the time of replication, both "you"s were completely physically identical. Both would wake up thinking that they are the same person that went to sleep, but now there are two of them. Are either/both/none of them "you"?

My answer would be that they both are, and don't think there's anything special about our physical selves, nor any reason that we're limited to being singletons (to give a code analogy). The combination of our physical self and our cumulative experience and memories are what defines "us". Thinking of identity in possessive terms and the desire to think of ourselves as unique is a quirk of psychology, I think.

Nobody "just dies". Most "natural deaths" are still heart failure. The rest are other kinds of organ failure.

For a lot of people that die natural deaths they could have lived longer if they had kept fit. It just gets really hard to either do or justify when everything hurts and gets harder to do year over year. Or when you are confined to a wheelchair since your early 20s, were told you would only live two years, and then beat that prognosis 27 times over.

But if you are able, even small amounts of cardio exercise could dramatically extend your health and lifespans in old age.

Stephen Hawking (along with Richard Feynman) are the reasons for my interest in the Sciences. There's nothing I can say now to thank him, but I will always cherish his works.

I'm not the poster you're responding to, but your observation about the distinction between P and p is crucial. The version of Bayes' rule that is relevant for the Kalman filter is the third one here: https://en.wikipedia.org/wiki/Bayes'_theorem#Random_variable... ("if both X and Y are continuous").
If they feel they have something to contribute, as small as it may be, why would they choose to die? No one would need to kill anyone off.
No it's not different. I just said that not many presidents have targeted and killed their own citizens. Lincoln was probably one of them. Perhaps one could argue Obama was in a civil war with Americans of the Muslim faith / extremists.

One could argue it was justified. I would personally feel horrible if it was justified that way. But, hey, it's not my country.
I can think of no higher praise then that he changed the course of so many of our lives personally and of humanity's understanding of the universe as a whole. Though small in physical stature he has become a truly giant set of shoulders upon which many more shall stand. Thank you for everything.
It is not hidden, we don't have a complete physical theory - quantum mechanics and general relativity are not compatible.

As an additional fun fact - we don't know how general anesthesia works.

We've had ~20 ratings but maybe 6 written reviews who have all had a great experience with it. From email correspondence with our users they are experiencing improvements in the topics they've focused on.

Regarding side effects, there isn't any unless you have a psychological disorder but thats in rare cases. Our tracks simply provide positive suggestions to your subconscious regarding a specific topic.

On a personal note, I've been using it every day and can honestly say its really helped me especially with my public speaking and procrastination and has helped me sleep better (a massive help for my daily productivity). I would recommend giving it a go if you have an iPhone and would be really happy if you could provide an honest review of your experience.

I'm not nearly well versed enough on the JFK assassination to comment. But flat-earthers are pretty much the stereotype of what I had in mind with my original comment.

If you go into it disbelieving, you find something verging on absurdist comedy. If you go into it believing, you come out armed with theories and explanations to reinforce your belief.

What I do find interesting, is without knowing enough to form my own take on the JFK incident .. this same model also fits the experience you just described. You go in with your mind made up, and you come out with evidence. Whether you're right or wrong, you'll find exactly what you want to hear.

But to my original comment - would a wiki summary describing the "establishment narrative" have swayed you at all?
Thanks for who you were and what you did. You will live on with us.
Stephen Hawking was very special to me. He's a large part of why I chose a life in science in general and physics in particular.

I'm just one of many, but he unmistakably and uniquely affected my life for the better.

Growing up, I read Brief History of Time and Universe In A Nutshell dozens of times each. I relished the jokes I got, and I won't forget him.

I also weep for him, knowing he never got the Nobel prize he wanted so very much.

I haven't shed a tear for many people in their passing, but I have for him.

Thank you for opening my eyes to the wonders of the universe. You are an irreplaceable part of who I have become today.
It really needed curation.

At worst, it was a mix of old advice, bad advice, dangerous code snippets, and people treating it like Stack Overflow.

Usually the first N posts were some really shitty solutions and someone would have to scroll way down to see a reply that calls them out and offers a good solution. But someone browsing the docs are most likely to use the first solution that seems good enough, particularly beginners.

Sorry what do you mean release a full version? This is a full version on one platform. Its important to validate that you're solving a real need and since we only know how to code iOS apps it made sense to focus on it first.

Native apps are a lot better in my opinion; i can really notice the difference between PWA vs native.

I think the more interesting comment is related to hiring an MBA for a startup.

Having just graduated with one, and meeting Michael at a lunch where he tried to tell us MBAs why we were bad fits for YC, I actually agree.

It’s certainly not a differentiator and while it got me a great job in a very traditional firm, startups need risk takers more than credential seekers (which I’ve come to understand is something I’ve actually become to some extent).
Even if there is only one possible unified theory, it is just a set of rules and equations. What is it that breathes fire into the equations and makes a universe for them to describe? The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing? Is the unified theory so compelling that it brings about its own existence? Or does it need a creator, and, if so, does he have any other effect on the universe? And who created him?

Up to now, most scientists have been too occupied with the development of new theories that describe what the universe is to ask the question why. On the other hand, the people whose business it is to ask why, the philosophers, have not been able to keep up with the advance of scientific theories. In the eighteenth century, philosophers considered the whole of human knowledge, including science, to be their field and discussed questions such as: did the universe have a beginning? However, in the nineteenth and twentieth centuries, science became too technical and mathematical for the philosophers, or anyone else except a few specialists. Philosophers reduced the scope of their inquiries so much that Wittgenstein, the most famous philosopher of this century, said, “The sole remaining task for philosophy is the analysis of language.” What a comedown from the great tradition of philosophy from Aristotle to Kant!

However, if we do discover a complete theory, it should in time be understandable in broad principle by
everyone, not just a few scientists. Then we shall all, philosophers, scientists, and just ordinary people, be able to take part in the discussion of the question of why it is that we and the universe exist. If we find the answer to that, it would be the ultimate triumph of human reason – for then we would know the mind of God.

Talk about beating the odds.

He showed ALS who's boss! He demonstrated that when you have a purpose and the will to live one can overcome their limitations.

He inspired me and countless of others.

R.I.P. Dr. Hawking.
His work will be built upon to make the next greatest discovery, but I don't think there will be a man this accomplished in the next few decades.

We miss you already, Mr. Hawking.
This reads like a pre-prepared obituary. No additional information regarding his death.
I'm genuinely surprised at all the disdain for it here. Coming at least from Spotify's scattershot mobile UI, Apple Music is straightforward, consistent, and, critically, performant (Spotify is the slowest-loading, non-game app on my phone).

Certainly there are gaps, particularly when it comes to sorting. But all this about bold fonts and button sizes seems to stem more from an expectation that a music app should be a dense, text-focused experience like iOS's email app than from any fundamental design issue. Given Apple Music's focus on album art as the primary identifier for recordings, the UI has an appropriate information density - one can argue that's the wrong priority, but if you accept that premise, the UI supports it well.
I know Google's overall headcount numbers for the next year, and while I can't disclose them, I'll just say this article is silly uniformed nonsense. In previous years, the reports they have produced have been off by a factor of 10 off what Google later reports in their SEC filings. So I'd take it all with a large grain of salt.
I wouldn't particularly feel better if the person who murdered and ate me felt a sense of reverence for me.
In ALS and other degenerative neuromuscular disorders one loses the ability to swallow effectively and protect against aspiration along with the inability to speak. People affected by this, like my grandfather, will usually require a feeding tube to allow enough calories without risking aspiration. However, even with this, we are constantly relying on our epligottis and swallowing reflexes to prevent microaspirations of saliva and oral bacteria. Because of this, people with ALS are at extremely high risk for pneumonia, which would be my first guess as being most likely. His was lucky in that his ALS was a subtype that didn't progress as rapidly as most do.

I think you don't deserve the downvoting you are getting even though the timing of your question is not great, you're still trying to understand what the natural progression of ALS is.

The same way the App Store on Apple TV still doesn't have an "Updates" tab with updates available for the apps one has installed. The only way to do this is to go to each app's page and see if there are updates available. It has been this way since the fourth generation of Apple TV with the App Store was released about two and a half years ago!

I've been repeating this a few times — Apple and its leadership ought to be deeply ashamed about such things, but never seems to be and doesn't show that it cares either. What ever happened to user experience being a distinguishing factor on Apple products???
Characterising this incident as "a routine community action" is concerning.

Hypnosis and meditation do share some similarities but are actually distinct neural states.

We think of meditation as cardio for the mind, improving your overall mental health and well-being through mindfulness. Hypnosis is more like strength training, where you focus on retraining the thought patterns relating a single behavioral area.

Hypnosis doesn't involve being mindful of your thoughts like meditation, instead you become hyper-focused on what the hypnotist is saying, so its actually quite different.
