> It taught me two things: what some of the noises, the vibrations, and the movements were; and how hard it is to actually crash a plane. Once you made it in the air, you'll want to try crashing your plane in the game (explosions! fun!), and it will be undoubtedly harder than you imagine.

It's a good thing you didn't try flying a virtual helicopter then, those things are deathtraps. I have some experience flying the KA-50 "Black Shark" in DCS and before you get a feel for it is very easy to make your rotors bump into one another and break (mostly due to its weird double rotor), get in a vortex ring state, or simply bump into stuff horizontally while landing.

Crashing is still fun, it just waaaay easier than with a plane. At least the board computer will whisper sweet nothings to you after you've lost most of your rotors and are once again falling like a brick... "watch EKRAN".

I consider this the colloquial sense: the speedup (or, more generically, the "increase" of throughput, quality, or other performance indicators) obtained by using quantum computers.

Unlike the irreducibly mathematical and very narrow concept of "exponential increase", which could be plausibly misunderstood, a quantum speedup (or increase) can be correctly abstracted to the trivial pattern of doing things in a different way which performs better, without really needing to understand the problem and the solution; it's very surprising to hear the term misused to mean "really big". How could it happen?
Except they don’t? Twitter is pretty big too. Facebook is just the biggest player.
I entirely agree with the author's points.

I worked on a device that used kirlian imaging to scan your body's health using only "finger prints". The founder of the company could tell from no prior knowledge that I had to pee at the time of the evaluation and I also had a back injury a few years ago. Lot's of people would argue this isn't scientific, but we used known diagnosis from current medical practices related to heart disease, we were able to establish 95% confidence whether a person was at risk of cardiac failure just based on their finger tips.
The technical equivalent of this is that BQP = P. However, we have some evidence that this might be the case, namely Raz and Tal's recent oracle separation of BQP and the polynomial hierarchy

I say there is no source of randomness because the universe is a closed system by definition. In this case by universe I mean all of existence. And closed systems cannot create randomness - it always comes from somewhere.

I suppose we can't rule out collapse totally, but we also can't rule out fairies pushing atoms around. It's just that there is no evidence for collapse, so it seems we can ignore it.

>Race is not a “social construct”. If that were true, I wouldn’t be able to blindly tell your race via a dna test.

This statement is not true. The racial information which can be determined via a DNA test does not necessarily match up with what that person, or others, would consider their race to be.

Saying "words are a social construct so you could mean anything" is not a good faith contribution to discussion.
I understand that this can be a sensitive area, but I'm pretty sure that more obviously assistive items wouldn't be dismissed quite so out of hand.

I'm also pretty sure that a trash can for the car isn't going to make that much difference for folks with mobility problems - there are too many other options already out there for trash collection/disposal including small boxes (e.g. a square or cube shipping box with $0.25 of hook side adhesive backed velcro stuck to the bottom).
Knuth (art of programming) is no average programming book. It is good book and worth effort, but it is no easy read.

You can read lovercraft or goosebump without any prerequisite knowledge. Greek or otherwise. Authors took care and effort to make it so. They succeeded. It was intentionally written to be pleasant and easy read, both their goal and skills were unlike those of Knuth. I used to read a lot of books like that, it is not that I would think bad of author of those books. I appreciate them for what they are.

Reading goosebump book and art of programming are not comparable actions. It is good argument for why counting books per year without context makes no sense.

Freedom of association is also an important general principle. For instance, I don't think many place any value whatsoever on the freedom of other people to speak in their own home. I certainly wouldn't let someone stay in my house while saying the kinds of things I regularly see on Facebook, and that's my right. I think this is quite an important property of our system, and I think most agree.

As a private commercial enterprise, Facebook itself is, for the people who own it, much like my home; they are free to set whatever policy they like regarding what goes on there, as long as they aren't discriminating against certain specifically protected classes of people. It's shortly tricky, it's not unreasonable to argue that a platform the size of Facebook should be treated more like a public space than a private one. But I personally think the bar for overriding freedom of association should be extremely high, and I don't think Facebook is over it. Those who have been disallowed to associate with Facebook remain free to associate with other very similar platforms.
I don’t see any discussion of idempotent processing or the Kafka transactions feature in the documentation, and I also see a mention of acking unprocessed messages in the form of acking if an exception is thrown in the application.

“Clear” is a weasel word propagandists use when matters at hand are anything but. Please provide evidence.

As far as I can tell, the main aim was (and still is) to sow division, and the ads targeted the liberal side more simply because their rhetoric was more aggressive. They went as far as organizing BLM and “resist” protests.

Facebook’s disclosure shows that they (whoever “they” are this time — FB was unable to pin this on anybody) are still doing the exact same thing and rallying the radical left, and racial/ethnic minorities.
First, realize you're comparing yourself to other people. I do it too, most people do it at some point. You are not alone. Sht like this takes time. No one is immune to feelings of inadequacy, just look at the recent suicides of Kate Spade and other people we deem successful.

1. Comparing yourself to other people is a losers game. You will always* find someone else who is smarter/wealthier/beautiful than you, and on the other end you will always find someone who is worse off than you. You are enough.

2. Practice compassion. I keep a "good things" jar on my desk. When something good happens, I write it on a post-it note and put it in the jar.

3. Track what matters in your life. What matters to me, and what probably matters to you, is maintaing health and learning a little each day. Break out a spreadsheet and learn how to be observant to your body. I recommend https://www.trackinghappiness.com/ as a start (I am not affiliated with the site).

4. As previous commenters mentioned, like-it-or-not luck plays a large play in life. However, that doesn't mean you can prepare yourself for when luck or opportunities arise. Based on your handle, you got an internship at Amazon. That didn't happen out of the blue. You had to network, practice coding, and build your skills to get it.

This is a hard thing. Don't be like me and beat yourself up over it because a complete 180 hasn't happened this week. Giving yourself time, combined with discipline, can lead you to the next step. I don't know what that next step is, but go find it.

Moderation is usually applied as having people direct their free speech back at you, not by taking away your free speech.

The part of your post about following hand signals of construction workers is interesting. Could anyone jump out in front of a Cruise car and direct it? Would you have to be wearing something like an orange vest?
Listening to the live radio communications on a flight was eye opening. Turbulence aside, I can usually feel when the plane is moving to a new altitude (either up or down), and while I always assumed it was planned, being able to hear the process of the pilot asking for clearance to move, getting clearance, and then feeling the plane rise or fall took all of the fear out of it.

This. I hope more people start thinking along these lines so that we can find a solution that respects and exploits the useful boundaries and incentives in the system, resulting in better science.

> For that to happen, we would need a group of already reputed and respected researchers to review the submitted articles. But because the journal fees would be avoided, that means the money could be collected to pay those reviewers.

Scientists are motivated by curiosity for their field, prestige, and having a stable job position were they can follow these motivations without fear. But they are not motivated by money (grant applications are a necessary evil). Due to this I don't think that you can start paying professors with stable positions, but you could start permanently hiring those many highly qualified mid-career academics who are still on the way towards a permanent position (and may never reach it). The review quality will be improved if people review full time, which can lead to journal prestige, faster review times, reviews with a broader look on science.
Why Coinbase and not Bitcoin will replace Mastercard
Funny how this thread surfaced now. I'm in a similar place.

I didn't use to fear flying until I got my first (and only) panic attack (not in a plane).

The trick I used to fight anxiety was walking around and it always worked for calming me down. But guess what, you cannot get for a walk on a plane so I started fear flights for a fear I might get a panic attack.
Long story short after lots of workarounds and googling I found that there's a company called psious[1] (not affiliated with them other than using their product).

You cannot use their system on your own (I asked) you only use it with a psychologist/psychotherapist.
Basically it works by exposing you to a simulated flight through VR and the psychotherapist helps you with tools like diaphragmatic breathing [2] and cognitive behavioral therapy [3] to ease your anxiety levels.

To be 100% open/clear I haven't flown yet since I started the therapy but I can tell my mindset has changed from trying to avoid flights at any cost to having booked flights and waiting (a bit anxiously :) but nowhere near at the paralyzing level) to actually fly.

Obligatory quote from the same author made in 1998:

> The growth of the Internet will slow drastically, as the flaw in ‘Metcalfe’s law’ — which states that the number of potential connections in a network is proportional to the square of the number of participants — becomes apparent: most people have nothing to say to each other! By 2005 or so, it will become clear that the Internet’s impact on the economy has been no greater than the fax machine’s

EDIT: Really? Downvoted for stating a true context fact?
From your description, it sounds like this event made a sudden change in how you feel about it. It was a fear that sprouted up immediately after a definite source. You had an earnest fear that you were about to die because you didn't know turbulence like that.

That sounds like some kind of mild case of PTSD to me. It's not always super-dramatic shell shock or trauma from war; any fearful event can give you some level of post-traumatic stress. When I was twenty I was run over by a van running a red light and dragged along the road a good way. I was fine, but after that I had a very hard time crossing the street without getting jumpy and having my hair stand on end. If somebody edged out into the intersection to turn left instead of waiting behind the line, it made me freak out and run across or even turn back. It was an extremely physical sensation, like I was losing control of my body with fear. It looked really silly to other people, and I was kind of embarrassed.

I'm fine now. Even going to Southeast Asia and crossing the chaotic roads there which have no signals isn't frightening, where people must steadily walk through a mass of still-moving traffic. I think it was a case of exposure. I had to keep going out there and exposing myself to something I was afraid of. I lived in New York back then, so I was obviously exposed to it countless times every day as a matter of course. Flying might be different because it just happens so much more infrequently.

In any case, I'm not a professional; I hope you'll excuse my amateurish diagnosis and personal anecdotes. I'd recommend talking to somebody with training about your situation and seeing what they think. Don't be embarrassed because this isn't the kind of harrowing event typically associated with post-traumatic stress. It can happen at a lower intensity with everyday fears too.

Yes, CBT is probably the best therapy for this kind of thing - in fact, phobia of flying is THE case study (very much their version of the todo-app :) ).

There are certain pieces of software like Putty, 7-Zip, Arduino Studio, Inkscape, Plex, and Notepad++ where I'd like to always have the latest version. A few of those are in the store and keep themselves up to date.

> Dont you want that control?

Not really. There's quite a few pieces of software I want to run the latest versions of for security reasons (e.g. 7-Zip and Putty), some where finding the latest Windows installer is tedious (e.g. Gimp) others updated so infrequently that I forget to check (e.g. Inkscape), and others that are updated so frequently that it feels like I'm always running installers (e.g. Notepad++). Plus I use no less than 4 different computers with that software and it is a paint to make sure they're all updated. I'd rather just let them get managed in the background.

Ask HN: How to pick an idea to work on when you love multiple?
I'm currently applying for Startup School, and I'm torn between two projects I've been working on.

The first is to build an early warning system for various diseases (malaria, dengue fever) and public health problems, something I've been working on in grad school and a few large orgs have shown interest in paying for.

The other is a personal preventative health dashboard that gives you dynamic predictive suggestions based on your diet, genetics, fitness and sleep data.

I have the experience and passion to build both, and they both actually slot into an ecosystem together, but one is b2b with long sales cycles and the other is b2c in a crowded health app market. One of the things I prioritize is maximizing the value I can deliver to the most people. What would you choose and why?

Also, if you'd like to hear my thoughts on these in more depth, I'd be happy to talk! I also wrote a short piece about it recently -> https://medium.com/technomancy/a-humble-proposal-the-human-healthcare-stack-e9e82eb8eff

We have a website and mobile apps. We are watching our revenue not so slowly go from credit card based purchases with a 2.4% transaction fee, to iTunes/Google Play purchases with a 30% transaction fee. This makes a HUGE difference in overhead for a business, and is money directly funneled straight to Google and Apple's "services" divisions.

I don't think this is going to change or level off anytime soon. Everyone wants their cut, now Visa gets it AND google/apple get it :(
