> It's all based on changing external conditions, mostly food availability.

Most people given access to unlimited lentils would not become obese. Food availability is NOT the only factor.

A core message of the article is that the food industry has lobbied against restrictions on advertizing to children food with habit-forming non-nutritive calories. The food industry is built around cheap production of highly-processed ingredients that addictively fuel consumption and sabotage health.
You're both wrong and mongering conspiracy theories.

Sure, the Academy has its flaws, and there are bad actors who are out there just for fame and money who will lie to enrich themselves. But that's doubly true for the "health food" industry and people who claim to be nutritionists.

Humans are terrible at introspection regarding health matters. Absolutely horrible. This is one of the reasons why double-blind test protocols exist.

And so, even if you are so paranoid as to think that the American Medical Association is engaged in some mass conspiracy to keep people sick, unless you are also writing off all health care researchers, you've got to admit that there are people who are trying to help people, and help cure disease (which lets face it, we're actually pretty damn good at, all things considered).
I believe ad-hoc files would handily have outperformed SQLite.

One reason is that SQLite does not use optimal disk access patterns. I know this because I have watched it issue nothing but preads and pwrites for literally hours, on a database that was about 2 GB. This is obviously terribly pathological behavior, and it was in shipping products. (incrVacuumStep is the bane of my existence.)

The second reason is that SQLite provides strong data integrity guarantees by default, at the cost of performance. This has proven to be a bad tradeoff for many applications, including Firefox.

> And the fsync() issues are orthogonal to using flat files/DB

They are not orthogonal, because SQLite calls fsync a lot by default, and it takes work to understand what you're doing that causes it, or even to disable it. See https://bugzilla.mozilla.org/show_bug.cgi?id=421482 for some of the pain this caused.

Notice some of the timing differences - one user reported that disabling SQLite async IO reduced his shutdown times from 1m40s to 5 seconds. This puts the lie to your "any kind of disk storage will be slow" claim: disk access patterns can have enormous impact, and empirically, it's easy to use SQLite in a way that destroys your performance.
To convert to more normal units, that is about 189 Mbits/second. Which sounds a little less impressive considering the peak 4G speed is supposed to be 100 Mbit/second.
Elon Musk, on the recent earnings call, claimed that their conversion rate for test drives was 25%.

Excerpt from the SeekingAlpha Transcript:

Amy Carroll - JPMorgan
The first question was just basically like when somebody comes to the door,
how do your stores – like what you're converting in terms of like actual sales?

[..]

Elon Musk - Chairman, CEO, and Product Architect
It's a low percentage conversion.
I mean a lot of people in and educate them about Tesla and the brand.
So that's our marketing strategy which is different from a typical car company.
And so just a typical metric of conversion for traffic is not exactly applicable.
I mean there's a lot of people that buy T-shirt.
Our apparel sales are actually not bad.
I think we could actually do a lot more on that front.
We actually have millions of dollars in apparel sales, but we're not really trying hard.
I think probably a better metric would be conversion after – of a qualified lead after a test drive.
And we're seeing something like 25% conversion after a test drive which is quite high.
That's a terrific place to set up Tesla showrooms. Apple has done all the legwork in figuring out where their target demograhic is, and Tesla can piggyback on it, like what Taco Bell does vs McDonalds. (considerable overlap between Apple customers and potential Tesla customers)

I think I'm outside the ages Tumblr is marketed toward, but when you say "freedom" are you referring to lack of censorship, e.g. pornography and other obscenities?
So tl:dr; don't be a scumbag with SEO and build quality websites with relevant content.
A lot of people still use a yahoo email. I suppose when they first got their email, it was supposedly better than hotmail (gmail hasn't even come out yet), and they haven't bothered to change since because, really, it's good enough. Yahoo messenger too, I guess. And probably a lot of people have yahoo as their homepage (for some reason...wonder why!) and never bothered to switch it to something else more sensible. That might explain how yahoo.com is still top 5 on Alexa[1].

I don't have a research paper to cite, but it seems fairly common knowledge that people who go vegetarian for a while --either by choice or by moving somewhere meat is scarce-- often have a period of re-adjustment when they return to eating meat; especially red meat. This is on a time scale of a few months in each direction.

This was addressed. Franchise dealerships allowed manufacturers to receive payment when the dealer took delivery of the vehicle. It takes a lot of variables out of the picture for them: how long will a car sit in inventory, unsold? How many of each model do we need to ship to various locales? What kind of service capacity do we need to provide?

Dealerships also allow manufacturers to have a "presence" in many smaller towns. In return, the dealers demanded (and largely won) protection from a manufacturer coming in and setting up shop in a market that the dealer worked to develop.

Tesla don't care about all that. They are fine with having a select few stores in large markets. They are fine taking all the risk of actually being able to sell their cars to consumers. They are fine with providing all the service. So I don't see what the NADA are complaining about, really.

And honestly, if and when Tesla really starts to get big enough to compete with traditional manufactures, some kind of dealer/franchise network is probably going to start to make more sense for them. Large centrally-planned organizations don't tend to do very well.
> They're rent-seekers, pure and simple, with no value add at all. Half the time they don't even have stock!

This isn't true. While dealers are slimy and have miles to go, there's still a consumer need to (a) a place to see/touch/drive a vehicle and (b) go in for service and repairs. You can't simply fix this with manufacturer-owned stores because the capital cost is so high. Major manufacturers like Ford and GM have over 3,000 dealers in the US. Maintaining that kind of network is something that dealers can't afford. Tesla only has a few dozen service centers right now, and they're centered around high-population urban areas with wealthy customers.

I'd like to see franchise laws change to encourage competition in the space, but I think we still need dealers in some form or another.
The (live) children's TV my daughter watches is on PBS. The extent of the advertising she is exposed to while watching it is the idea that giving money to PBS allows them to continue to show the TV programs. The other children's TV she watches is on Netflix, with no advertising. While some of those shows exist because of advertising during their first run, if that option weren't present then something would fill the void.

Anyway, "advertising to children" is already specifically defined and regulated in many countries. The question is simply how far to take those regulations under existing definitions.
Where's the intuitive arena of rightness for the Collatz conjecture? I would put an 'or' between #1 and #2 (with #1 being less preferred; why would anybody start checking whether P holds for a large number of trial cases without having a hint of #2? (How did Collatz came up with this conjecture?)), and add a #3: the conjecture isn't easily disproven ('easily' being subjective, but the other two are subjective, too)

Is the bound achieved by his proof actually 70000000? That looks like a suspiciously round number. Why can't they tell us the exact bound that he achieved? (Presumably some slightly smaller number?)
I believe the goal is to survive.
I decided to do a bunch of numbers about getting off each respective rock:

Using a = G * M/r^2, we get the following:
For Mercury:

AMercury = G * 3.29e23/2.44e6 = 3.68 m/s^2

ASun@Merc = G * 1.99e30/5.79e10 = 0.039 m/s^2

Atotal (if you launch off the dark side) = 3.68 + 0.0039 = 3.719 m/s^2

For Earth:

AEarth = G * 5.97e24/6.37e6 = 9.81 m/s^2 (duhh)

ASun@Earth = G * 1.99e30/1.49e11 = 0.0059 m/s^2

ATotal (off the dark side) = 9.81 + 0.0059 = 9.816 m/s^2

So even if you launch the 'hard way' from both planets (shooting away from the Sun), the gravity well you're in to get off Mercury is less (37%) than that of Earth, thanks to Mercury's far smaller mass. This isn't surprising, given that the local body completely dwarfs the influence of the Sun in both cases.

I don't have my lecture notes at work so I can't do it fully, but off the top of my head this is a rough first pass at the relative difficulty of transfers between each planet:

Earth orbital velocity: 29.78 km/s

Mars orbital velocity: 24.08 km/s

Mercury orbital velocity: 47.87 km/s

Venus orbital velocity: 35.02 km/s

d(Earth-Mars) = 5.70 km/s

d(Earth-Venus) = 5.24 km/s

d(Earth-Mercury) = 18.09 km/s

So in short, you need to change your velocity by 3x - 3.5x as much to get between Earth-Mercury, as you would between Earth-Mars or Earth-Venus (which are quite similar). Given that kinetic energy = 0.5mv^2, that's a 9x - 12.25x factor of energy to get to Mercury vs. the other two.

In summary, to get off Mercury is easy compared to Earth (duhh) and the Sun doesn't make any difference there. To get between the planets however is a huge difference and will be the limiting factor on regular Earth-Mercury transfers of matter.

Regardless of which way you go (towards or away from the Sun), you need to either shed or add the respective velocities to change from a circular orbit at Earth's orbit to a circular orbit at the other bodies' orbits.

I noticed when a discussion like this comes up people separate themselves into two camps that mock each other's assumptions while both talking about the same thing. It would be nice to talk more concretely with benchmark numbers.

1. What about a database saves you disk space? Whatever it is, the filesystem can do the same thing. Perhaps you had a preconceived notion of a specific filesystem and OS in mind when you wrote this.

2. Your database MMAPs/caches pages with its custom page buffer too, and that wastes ram with small records.

3. Reading/writing data from a database requires syscalls too. An OS can cache a lot in memory and minimize disk writes. Arguably the database is duplicating the caching logic of the OS and slows things down.

4. Filesystems have atomic transactions too. You can use the flock call to lock files, and rename is atomic. It's a rather befitting hack for HackerNews which "atomically" renames a file to update it.

5, 6 and 7: You can get distribution, replication, fault-tolerance, availability, and snapshots for free out of a filesystem like GlusterFS too. (Also note SQL is crap; it's a bad serialization of a data structure.)

I wonder if the real reason we have better databases than better filesystems is people didn't want to program for the kernel, which is where filesystems had typically ran.

People not grasping you can store data on a filesystem is probably one of the most valuable things a new programming language would have going for it. It would be a staggering reduction in complexity if a language made data manipulation easy, perhaps at the dismay of programmers stripped of the amusing complexity of using this separate thing called a database.
Tesla is exactly doing that. If you think that is a guaranteed failure, I take it you are short on their stock?

Because obviously we need not institute new laws if basic economic reasoning can bring about the change.
You actually bring up a great point about the Yahoo's homepage.

No, that's exactly my point. Hiring would be occurring now because the economy is recovering from the recession, but at corrected wages that do not reflect an artificially bloated cost of living in particular localities.
Why do there need to be laws specific to that? Aren't companies like Tesla capable of deciding if they need more or less service centers, in what locations and what model is best to run them?

Ha, this was one of my prior "failures" but being an introvert is not a "failure" per se. Shortlisted was designed to consume any information an organization had about an employee plus a 1 to 10 rating about the value of each employee to the organization.

The algorithm would then perform a step-wise regression on all the data and "distil" it down to a model of attributes that correlate with performance to that specific business, not in general. So being an introvert might be great for some business cases but may not correlate well with success in every case.

After the model was built, the second step in Shortlisted is to take another huge chunk of data and look for new employees that had attributes that correlate well with success for the business.

So a typical use case might be your company hires 10 engineers out of college per year. Out of those ten you can rank them in approximately highest to lowest in terms of value to the company. Shortlisted takes everything you know about those 10 (plus any from previous years, it really takes about 30 data points to produce meaningful results) and searches the University for more people like the most valuable employees and tries to avoid people like the least valuable.

Our goal was to help job seekers avoid situations that not going to be a good fit, and help employers find new hires that had a high likely hood of success.
No one knows what food is healthy and what food isn't.

Full stop.

The more you read about this, the more you realize it is so. Government advice and regulation about healthy eating has likely been a contributing factor to a huge explosion in chronic disease. Enough is enough, improve and expand mandatory food labeling and stay out of the rest.

Meanwhile, no one should market anything to kids, if you really think about it.
I have a solution to the obesity epidemic, that would be realistic to implement. Right now the factors for what we analyse in nutrition is calories, macro nutrient content, and micronutrient content. What we really care about is satiation and satiety. These are words that no one talks about, and but get to the core of the issue. If I eat this food, how many calories will I consume before feeling full?(satiation). After eating this food, how long until I feel the need to eat again? (sateity).

Unfortunately the research and measurements of these values is thin. We need to fix that. We already know things like whole milk better provides satiation and sateity than skim milk, and children that drink whole milk actaully have less obesity than skim milk drinkers.

If we just measured and labeled foods with a sateity/satiation index (what we really care about), then people would actually have a chance to pick better foods. Right now it is damn near impossible to determine if eating eggs and bacon for breakfast is more likely to drive over eating vs cereal. It can be measured, but we just don't do it.
"Terraforming" is just a concept. We have no idea how to do it and whether it's even possible. And even if it were, it would take hundred of years and would need constant life support from Earth for that time. Hardly a good bet either...

This is the massive change afoot that Hollywood needs to recognize. 20 years ago they were fighting over which network you would watch or which film you would go to see. But now the entire Movie/TV industry has to compete against other forms of entertainment. While you can argue that this has always been the case, computer-based entertainment is a lot more "TV-like" than going out to a concert or seeing a play. I think this long term trend poses an existential threat to the TV and movie business. They are going to need to adapt to this new environment or risk irrelevance.
It's also worth bearing in mind the needs of the many, vs. the needs of the few.

With the kiddie porn issues, generally the number of children being talked about is a very small minority of the total, and usually the issue under discussion has only indirect possibility of helping those children.

However advertisement of poor food choices to children is something almost all children are subjected to on a daily basis, therefore when discussing regulation we can see that the majority of children will be beneficiaries.

Mayer is cobbling together a new set of Yahoo properties via acquisition, but that won't change the perception of Yahoo with younger demographics.

Yahoo's problem is that they have no gorilla products. They have no big, dominant product/s, that generates billions in revenue, and is still growing at double digits. There's no core to what Yahoo is, so they're on a perpetual treadmill of buying other sites / services to replace dying sites (eg Tumblr for Geocities). So long as you're buying other sites to supply your core, you'll always be running behind (not to mention it requires incredible vision to buy the right sites / companies).

The history of the Web says that the dominant players all have gorilla core products that provide moats.

Go to Yahoo.com and tell me what you see... it's still a boring portal from 1999. They're not the leader in search. They're not the leader in social. They're not the leader in mobile. They're not the leader in cloud services (eg AWS / Azure / App Engine etc). They're not the leader in image hosting / sharing or streaming video or music. They're not the leader in email. They're not the leader in web gaming / social gaming.

So Mayer is going to buy Tumblr, which will chase off their most loyal users. Then Yahoo is going to have to figure out how to pay for the billion dollar acquisition, which will chase off even more users. And in the end, the best value they can ever derive from Tumblr will be portal style integration with yahoo properties, which is something they could have gotten in a simple deal.

A lot of people are looking at Flickr as a reference point to this deal. Yahoo paid $35 million for Flickr, and it had a functional business model that is still alive today.

This is a bad joke on Yahoo shareholders.
"Major manufacturers like Ford and GM have over 3,000 dealers in the US. Maintaining that kind of network is something that dealers can't afford."

I don't see why 1 company couldn't maintain that many locations. Walmart has 10,857 stores[1]. Over 4,000 in the U.S. and over 6,000 internationally. I would argue that maintaining a single Walmart store is more difficult than maintaining a dealership and yet they're able to make it happen.
