Why Not Have a Randomly Selected Congress?
Understandable and no complaints, down-votes taken with a smile and not personally.

I don't understand your point about "demeaning" though.

Are you saying calling people under nurses care "flesh" is demeaning? Or saying the word "Nurse" has mammary overtones (it does, and I assume some sort of common root) is demeaning?

I would have down-voted the comment for being dumb rather than demeaning (admittedly it is kind of a dumb comment).

Just struggling to understand demeaning here because I'm not the kind of persons who wants to demean so maybe I should know something I don't.
Why getting traction is so hard these days
For books, you have to generally read them like 5 times. The first pass might take me like an hour, it's mostly to establish a general mental framework for what's in the book (actually try to read the table of content, and like familiarize yourself with the words you might not know). On the second pass, you will actually try to read the book and retain like 20% of what you read. On the next one try the next 30%.

This approach has the advantage that it lets you decide what's important. I also like to believe that it establishes better connections between the single ideas.

I would say that goals are counterproductive until you are somewhat comfortable but not when starting out. Like yeah sure, you should make some progress but you are in an uncharted territory, the best thing you can do is to walk around a bit and make sure you stay engaged.

If you move to a new city, you probably walk around the neighborhood for a bit, then to the neighborhood next to yours etc etc.
the situation here is a mentor told this to Randy. In that context, this conversation probably has more of an effect. in any situation I think the lesson still applies, a person will be limited if they continue their behavior no matter how much success they have, they could have accomplished more if they had dropped the attitude problem.

People with enough money can already just buy a second seat or pay for business/first class.

This actually opens up increased comfort options for those with less money.
What is the right way to think about this? If we observe a supernova 600LY away, do we say that event is happening "now" from our frame of reference? Or should we think of it as happening "600 years ago", and the light from the event is only now reaching us?

If you think of causality itself moving at the speed of light (which of course it does), and think in light cones rather than referring to a nonexistent universal frame of reference with an authoritative clock, the "now" language seems more appropriate. Intuitively, it also feels quite wrong — but I attribute this more to a failure of intuition than of language.

And how come Apple Pay is so much faster than the chips + signature or chip + pin method?
International flights are usually undersold.

I pick the middle seat. People will just opt for another row with a window or isle open and the middle seat open so they can have some space.

I often end up with a row to myself.
I assume this is only in the case of a non fully booked flight. But I didn't read the article.
I'm not saying that there were no good old games. What I'm saying is they benefit from the same effect as old movies and books, where the best remembered and preserved titles are good ones and the crap is mostly forgotten about, leading to an unrealistic perspective on how relatively good or bad the medium writ large used to be. For every Super Mario Brothers 3 there's a Mystery of Atlantis.
> Same here, I never understood why people were initially so enthousiastic about iTunes or other players after Winamp that tried to hide your audio files behind a convoluted GUI and that abstracted the files on disk into a crappy, opaque database.

A pure hierarchy can't handle compilations or playlists very well. A database, a real one, ought to be the solution - my best player experience was with Amarok 1.x which let you use embedded sqlite or connect to mysql/postgresql.

I don't feel like I want a whole lot from a player, but I do want to queue a track or two while leaving the player on shuffle, to play individual tracks out of a cue/flac, integration with some service that can tell me when a band I like is playing near me, and ideally a recommendations service too. So I've generally ended up with the heavyweight players.
Since chip-and-pin seems to be used as an excuse to push liability for fraud onto the cardholder, I'd much rather stick with chip-and-signature. If we could have chip-and-pin while still keeping me at zero liability for fraud, I'd take it.
AMP is the perfect way to punish big publishers for their slow websites. Google can't punish them by simply lowering their rankings, people want to see those big publishers.

HLL is for calculating the number of unique objects when there are possible duplicates. Unless you're doing something really weird you shouldn't have any problem going through all 20 million objects without encountering duplicates.

You're probably better of just keeping a running total. You can either update this total online (keeping track of all state changes) or whenever you need to know (going through a mere 20 million items shouldn't take too long).

If, for whatever reason, you really want to approximate it quickly, just pick a subset at random and calculate the percentages from there. Some basic Bayesian statistics can tell you the accuracy of this approximation.

There's an ill-informed article complaining about Tesla's stock price about once a week. There are good reasons to think that Tesla's valuation is awfully high, but these articles seem to repeat every wild accusation or reason that they can find.

Good to hear from a Bolt owner on HN!
This is really interesting from a game theory perspective.

What's really going to matter is how it's executed. If someone bids $100 to keep a seat empty and the flight is empty, do they still get charged the $100? Or is it only when there's a limited number of empty seats and more people that will pay to have an empty seat next to them.

One interesting way would be that each person gets charged the lowest amount of everybody who has an empty seat next to them. This obviously limits what the airline makes, but keeps things generally fair.

Another way is when people go to reserve seats, if someone is willing to pay $x to keep an adjacent seat empty, the price of selecting that seat goes up by $x. This guarantees the airline gets paid at least $x as soon as someone bids that. It also makes it more important to book seats early, but will of course, get much more complicated to execute.

One of the things I do when booking flights for two, is choose an aisle seat and a window seat. Odds are if the flight is not full, a solo traveler will not book the middle seat, and we end up having all three seats for us. If someone does book the middle seat, we just trade aisle/window for the middle, so we're together, and he other person feels like he got an upgrade.
I've found that I can manage a day without taking in any calories, if I'm willing to feel really tired and have a moderate headache by ~1pm, and be horribly brain-fogged and useless by ~2pm. I've got a job and kids to take care of—I can't afford to have days like that very often. The hunger's not a problem—it's that I feel rather ill by mid-afternoon.

FWIW I rarely eat breakfast, so I guess I'm usually doing the (lame, IMO) "16/8" fasting pattern, though I'm skeptical that has any benefit.

That seems to be more than an optimization for a specific CPU. Sounds like someone refactored an infinite loop away.

Right, but users don't care about the reasons why it's faster. They just know it's faster. Hence they use AMP, and AMP gains traction. We can say it's unfair, but that's life.

If we want to defeat AMP, we have to beat it at its own game. That requires us to come up with an alternative that's equal or faster than AMP. And clearly we've failed as developers to push for non-bloated solutions.

It might be possible to create our own version of AMP -- to take the best ideas from AMP and integrate it into some centralized system that isn't controlled by Google. It'd be tough, but the alternative is to let AMP steamroll us. A few rebellious developers aren't going to make much difference in terms of total AMP adoption.

Even if the AMP alternative was just a standard way of stripping bloat from websites, that might get us 50% of the way toward beating AMP.
Cool! I just went and looked at WP's list of Dreamcast games[0] and honestly, besides Ecco, Seaman and Shenmue there's nothing from Sega I want to play. I'm hoping they do as good a job at bringing third-parties along for the ride as the JP PSN did for PS1 games.

I'm all for supporting innovation and community services, but I think author is not mentioning other possible causes, like DMCAs, malware and spam (including unintended), which could have damaged the reputation.

I just wonder why MIT didn't give more time to move and why it doesn't provide a replacement in eg cloud credits.
I'm quite certain that they could have just taken one of the empty seats and you would have been powerless to prevent it. However the English are polite to a fault.
So basically you find market economics is unsettling?

If it makes you feel any better there's not a single flourishing command economy anywhere in the world right now. China, Cuba, etc. are all moving towards market systems for a reason.

If history has taught us anything, it's that humans will create power gamification in all situations. The market system is the only way to harness those instincts to a somewhat greater good.
You do have the choice... The only part that forces you to use Google's cache is to get on their search carousel, but other than that, you can still use AMP and not their cache.
Kubernetes and the Age of Zero-Downtime Deployment
I tested both 64 bit variants a while ago and there was no throughput difference worth mentioning with the C++ and C implementations, respectively. (I settled on xxHash since it's around for longer and the code is portable, also I didn't need to do a C++->C translation).

If there is a large difference, perhaps one of the implementations is vectorized or botched.

I'm flattered that you want to talk about me, but I'd rather talk about the code.

That's really the only interesting part, isn't it? All the other stuff is just minor bugfixes / bikeshedding. I said "show me" the version of tag() that does the static_assert, and "show me" a version that adds invariant checking (that the cast is possible). Neither of these things have been shown. I'm not claiming it's impossible, just that subjectively, this version is worse than doing things the boring way.
Good salespeople actually do care!
That sounds like a horribly leaky abstraction if you mean that you're literally going to statically track the call stack to attempt to verify invariants. Hopefully it's just a misunderstanding on my part.
Did you pay for a whole row? If not, I can understand why people were upset...
Records are actually a very very long-lasting information storage medium, better than magnetic tapes (even when you put redundancy checks on them). So much that sometimes when music from the 1940s to 1960s is to be restored, restauration experts use the record rather than the master tape, which is more subject to degradation.

As for degradation, in theory there is degradation every time the record gets played. In practice tests done in the 60s show that records can be played over 1000 times without significant deterioration of audio quality.

However, the record surface is very susceptible to damage. This means that, play a record over a worn stylus, or under a turntable with a too heavy tracking force or a poor quality cartridge -in short, a bad turntable-, and the record will wear down rather quickly, sound quality will be degraded quickly.

Some years back my wife and I decided to write a series of apps for toddlers that had zero ads, and absolutely no annoying sounds or music. We wanted to make something your kid could play quietly, without any help. The iPhone/iPad app version has been down for a while since we didn't profit enough off of it to continue paying the $100 annual apple developer fee. The Amazon version is still up if you want to see what we had in mind. It's called "Quiet Toddler Games for Tablets" when you search under Apps. I still like the concept, it's too bad that it didn't really pick up.
Your second point is a great point, and I believe that there should be a user prompt every time something tries to read from the password database over any API.

Here is the key insight (from, in my mind, Gilbert Ryle originally):

There is a difference between knowing that, and knowing how.

When you want to learn that something is the case, read.*

When you want to learn how something is done, do.

If you want to learn how to do something, and you are not doing the thing, then you might find yourself not learning.

* You can take notes, summarize, and repeat.
The SSME also has to run from sea level all the way into space, whereas the Merlin is able to have one design optimized for sea level and a second design optimized for space.

The difference in efficiency is striking. The SSME's specific impulse (the closest equivalent to MPG in a car) is 452 in vacuum and 366 at sea level. Merlin's is 311/282 for the sea level version, and 348 for the vacuum version.

Of course, this is not a criticism of Merlin, just a comparison. By being less efficient, they're able to optimize for other stuff like cheapness and robustness.

How can MIT people use IPv6 when it hasn't been rolled out on campus yet? How does it make any sense to put the campus (Ethernet) network behind a NAT, when MIT still has 18.0.0.0/9, half of what MIT has before but more than plenty to go around?

Eventually, someone asks the question, "Why can I buy weed with Bitcoin, but not pizza and chips?" And delivery of munchies is a legit business that can be advertised. Once recognized as a viable model, it can then be poached by major corporate players as part of a local pilot program, which can then be rolled out to larger jurisdictions.

The problem, as usual, isn't that you can't buy anything with it--it's that you can't buy everything with it. As long as you can't pay your electric bill with cryptocoins, the business that accepts one as payment can't also pay its employees with that same cryptocoin.

Honestly, would you even apply to a job posting if it said salary to be paid exclusively in Floopcoins?

From an energy point of view, it's true that 1500 calories of sugar is the same as 1500 calories of cheese. It's also the same as 1500 calories of sawdust. In a lab, you can burn each of these samples under a bomb calorimeter and they'll all read the same thing. There's no debating the scientific definition of a calorie as a unit of energy. My argument is that it's extremely disingenous to just say a calorie is a calorie when it comes to a living organism, because the metabolic pathways for each different macronutrient are so different. It doesn't really matter how much energy a food has, if your body can't use the energy contained therein.

The moment that you accept that macronutrient composition is very important for health and body composition, you acknowledge that in biological system a calorie is not a calorie. If I want to lose weight, I don't want someone to tell me that CICO so I can just eat whatever as long as I stay under x calories, because as you rightfully pointed out some foods are more energy dense than others, cause fewer cravings, and don't spike your blood sugar. With CICO, I can lose weight but get fatty liver disease, or I can lose weight but lose muscle while increasing visceral fat, since fat weighs less than muscle. These are terrible outcomes. People want to lose weight to be healthier and look better; what's the point of losing the weight if your risk factors for metabolic syndrome go up and you still look fat in the mirror?

For the anecdotal evidence you provided, I think it's not as simple as how you've portrayed it, because your body can be in two energy burning modes, glucose burning or fat burning. If you eat more fat while in glucose burning mode (which is what most people are in), it will just get stored as fat and yes you will gain as much weight as the amount of calories you ate. In so called 'fat burning' mode, your body will increase its metabolism to burn off the excess fat. Likewise, if you're in fat burning mode and you eat more carbs, they'll just get stored as fat. This is also anecdotal evidence (sources: https://intensivedietarymanagement.com/who-needs-to-avoid-fa..., https://intensivedietarymanagement.com/smash-the-fat-calorie...), because unfortunately we don't really have good nutritional studies about this.
the last lecture is a good lecture Randy Pausch gave after being diagnosed with pancreatic cancer at Carnegie Mellon University, check the video out, I first watched it while in college and found it inspirational

what my point was here, is in this situation I think it is difficult to argue if Linus (And our IT community at large) had more of an attitude like the 'Lucky Ten Thousand' [0] not only would I think that have a much more positive effect on our code, it would in all aspects of technology and culture. yes you can easily have success with arrogance (I certainly have the problem every once in awhile albeit I usually vent when alone not at others unless it was started by someone else) that is not the point, the success could have been bigger and better if people worked together. personally I would like to see true open source GNU/source-phone(pardon the name) installation on smartphones so we stop having to sell our souls to apple/google/other major player and see solutions like that could be obtained with more cooperation and well reasoned and calm debate rather than inflammatory remarks.

##this part is a rant and can be safely ignored.
just to add one more note, compare reddit and HN. I think you will find people solving more complex issues and having more elegant solutions and discussion on here rather than Reddit... I find it is unfortunate that we sitll need to censor ourselves here because there are some topics that generate very emotional responses (my opinion) rather than being able to have constructive conversations, in order to keep the beauty we have here we have had to self sensor some topics and that makes me sad, I love this community and the discussions we have here, but if we cannot figure out a framework to have healthy debates about taboo topics, how can we expect others? I realize that is an elitest comment but there are a lot of smart people here and we still struggle.

If you're flying with another person, you can try booking the window and aisle, then hope the middle doesn't get filled. If someone does take the middle seat, they're usually willing to trade so you and your partner can sit next to each other.

Good question indeed. Why didn't MIT give more time to move, and in fact gave absolutely no notice, such that WMBR, the campus radio station, had to scramble to get their online radio back online again?

It is happening in our NOW and that's all that matters from a cosmic perspective, since no signal can travel faster than light. In that sense there's only the NOW, even when you're observing your friend a few meters away. We might say that physics itself travels at light speed.
While it seems great to be able to take a picture, that’s going to be very hard to know what’s in a sauce, stuffed inside of something, complex presentation, etc.

Why not be able to search over a list, and once on an item, show frequently related (e.g. garlic if you search onion). It may not involve any “AI,” but it’ll be far more accurate and easier to implement.
