For most customers, maybe, but I suspect there's a pretty sizable portion of the population (myself included) that will happily pay more for an airline that treats me extraordinarily well, considers my comfort while on board, and gives me reasons to shout their name down the street. For example, Virgin America is one of those airlines for me, and I will happily pay a premium to fly one of their tragically few routes (they're one of the few airlines I fly first on, as well). I blacklist Southwest entirely because of the complete disregard for my experience shown on the three miserable flights I've had with them. I don't think I fit in your business bucket, but that's a data point, at least.

In another industry where profit is the focus, domain registration, I'm absolutely dying for a $100-$200/year registrar that knows what they're doing and isn't awful to deal with. I will happily pay that premium since my hosting bill far outweighs my domain registration, and handling support tickets expediently and providing features I want are far more important than the bottom line to me. If an extra $10/year from all customers means I get IPv6 glue or a ticket answered inside of 72 hours, please, do it! (This is less relevant now, but was a concern for me in the past.) I'm willing to part cash to be treated better in almost all cases.
This looks like disk page corruption.

In such a case, the very first thing you do — aside from verifying that your backups, replication, and WAL archiving are all working — before you even try diagnosing your problem any further than "something weird is happening" is make a filesystem-level copy of your PostgreSQL cluster. (If you're running LVM, ZFS, a SAN, or any other thing that lets you take an instantaneous filesystem snapshot, so much the better. Do that, and then copy it.) Then, and only then, should you even contemplate trying to un-fuck your database.

I cannot stress this point enough. That means make a tarball, or cp the directory, or rsync it, or whatever disk file level tool you prefer, and specifically and emphatically not pg_dump. (It's probably not going to make things any worse, but if you do have corrupted disk pages, pg_dump isn't likely work, anyway.)

Flailing around trying to fix things can sometimes make them worse. If you're working on your already broken data, and break it further without the safety net of a fs-level backup, you're ... well, you're worse off than you were five minutes prior, aren't you?
It reminds me of the old quip "We lose money on every sale, but we make up for it in volume."
Agreed. I'm almost exclusively flying Jet Blue and Virgin and upgrading to their extended legroom seats at this point. I'm 6'2" and overweight -- not a good mix for the horrid seats in most coach sections.

The problem is that most of those implementations--even the OCaml one--are much more awkward to use than the Haskell version. So people don't.

In Haskell, the type system--thanks to typeclasses--can figure out how to generate random inputs automatically, just based on what type is expected. Even if you have a custom type, it's incredibly easy to define how to generate elements and then use it everywhere. Or you could easily randomly generate values in an ad-hoc method wherever they're used.

This takes advantage of the fact that in Haskell, values can be polymorphic on their return types. As far as I know, this is a feature unique to typeclasses--and very few languages aside from Haskell support those. (I only know of one other: Rust.) This, combine with Haskell's usual popular abstractions like Applicative Functors, makes writing QuickCheck-style properties and new random generators much easier.

Of course, this particular reason has nothing to do with functional programming and everything to do with Haskell's glorious type system. However, functional programming does play a role in QuickCheck's popularity as well.

Basically, QuickCheck-style tests are primarily useful for code that does not have side effects. QuickCheck lets you check some invariant by evaluating the same function hundreds or thousands of times with randomly generated input. This style simply does not scale to non-trivial non-local state, much less actual IO.

So even if your language had a usable QuickCheck library, it would only be useful for the more functional parts of your code. As the article points out, unit tests push you towards a functional style to some extent. QuickCheck does this far more. And so most people writing rampantly imperative code in wantonly imperative languages simply don't use QuickCheck. Even if some intrepid soul has ported it.

It's against US law to touch aliens.
heh, "courtesy of the US taxpayer". What you mean is "put there by the US taxpayer". Germany didn't ask for the US to put military bases everywhere, that just grew out of the victory conditions enforced on it from the loss of the war. It very much serves US interests to have those bases in Germany - the idea that it's all a unicorns-and-rainbows gift from the US is nonsense.

Looking for Interaction Designer and FE Engineer as a potential co-founder
This might be the most important post of our lives.

We are two engineers working on early stage ideas in health domain (think machine learning on medical data) and looking for solid UI designer as a potential co-founder.

Who are we?
1. UIUC ECE PhD, currently at big name place in the silicon valley.
2. U-MINN CS, currently also at big name place in the silicon valley.
3. We are pursuing this because we believe we can build a better product than what is currently out there.
4. We are not doing this to be cool. We are cool enough already.

It would be easier for us to work with someone in the valley but we can try to work around that for an exceptional candidate.

If you have a pointer to any of your previous work/portfolio, that would be appreciated.

Thank you very much...
In 2006, JetBlue removed an entire row of seats:

JetBlue estimates a net savings of $30 million over five years by removing
six seats from the A320 fleet, as a result of reducing the inflight crewmember
team to three, and by reducing the weight of the aircraft by approximately 904
pounds, which will lower the fuel burn. That figure includes lost revenue
opportunities as a result of selling six fewer seats per A320 flight. The figure
does not include any revenue improvement that may result from the enhanced
JetBlue Experience.

Wolframite here: these would make a good summer school project for our summer school (plug: the 2013 one is coming up, apply at https://www.wolframscience.com/summerschool/ if you're interested in this kind of stuff and want to do a 3-week project).

In fact I studied the space-filling behavior of precisely these 2D Turing machines in 2009. For low numbers of states and colors you can enumerate them exhaustively and calculate the distribution of space-filling efficiency (log-normal, if anyone is interested).

The full spectrum of behavior is quite fascinating to catalog. All these kinds of simple computational system have a character and 'zaniness' all their own.

Putting on a more scientific hat, it might be interesting to look at block-entropy measures and find interesting rulesets that way.

P.S. To the author: this is a great implementation! Really nice to play with. Check out http://reference.wolfram.com/mathematica/ref/TuringMachine.h... for the one built into the Wolfram Language.

As a tall guy I like to complain about airplane seating all the time. Once in a while I'm able to coax them into giving me an exit row; but that's beside the point.

Even with my height, I have not bought a plane ticket in the past 10 years with any brand loyalty or concern for comfort whatsoever. I don't even really care about the airline's track record of promptness, because the odds are still mostly in my favor it won't happen to "my" flight. I fly on whatever airline [insert flight pricing aggregation service here] says is the cheapest for my itinerary, maaaaybe taking into consideration that I might pay a bit more for nonstop, but even then sometimes if it means saving 50 bucks, for some reason I'm willing to go through the trouble of a multi-stop flight.

That would be my take anyway. A big issue with Java is that it required installing a huge standard library - that should just be downloaded as required. And flash was never really intended for applications; it was always about "rich content". And Air (the application framework built on flash) has the problem that it's proprietary so you have to trust Adobe.

Constitutions for the most part are not about describing human rights. They are about describing the method of governments - who is elected where and how, what authorities they have and so forth. There's usually some flowery preamble at the start about how awesome we all are in country -foo-, but the role of a constitution is generally to describe the structure of government.

Right, but Palo Alto/Mountain View are pretty much like Nebraska in terms of what you'd see on the street (super-rich Nebraska, though), and they also have plenty of startups, so it's not just bare hairy man ass that generates startups.

A potentially interesting way around this is to make the client open source and get it shipped by all the Linux distributions. That would give application developers an initial audience which would help solve the chicken-and-egg problem.
Interesting, I'm just guessing. Since Dwolla operates in the US, from the recent regulatory announcement targeted at bitcoin(or any online currency), I'm just thinking that Mtg.OX not registering itself in the US, it won't be able to do business directly with US entities. The Ars article http://arstechnica.com/tech-policy/2013/03/us-regulator-bitc... would lead me to believe the money laundering is the most likely aspect to run afoul of regulation at the moment.

However, I have little insight, it just seems the most likely reason to me.

> I fly on whatever airline [insert flight pricing aggregation service here] says is the cheapest for my itinerary

Then you must not fly Southwest, since they refuse to pay fees to "free" aggregation services, and you therefore have to buy the tickets direct.
Do you really think these guys think the same things we do when we mean "patent reform"? If anything they will make it worse (and better for corporations). They do represent corporations after all. And do you really expect Microsoft to want to "fix" the patent system? They make money out of it.

Many of these are quite beautiful.

The NKS-style question to ask here is: what computations are these doing? Totally unique-unto-themselves computations? Potentially useful computations? Computations analogous to familiar human ones? How would we know? Can we know? Do we run into the limits of undecidability?

The cyclic boundary conditions somewhat 'spoil' things, though. Maybe a particular rule was "destined to multiply input by 5" or "calculate log-2 of input" or something (given suitable encoding of input on the tape), but the computation is foiled as soon as the machine wraps around and starts interfering with itself.

Then again, the self-interference is what makes many of these patterns do the cool things they do.

Well, I'm not a statistic, then. I stopped flying United because I don't fit comfortably in their "normal" seats; they took the inches from the "normal" seats and put them in "Economy Plus" rows.

And, oops, you can't RESERVE an Economy Plus row when you buy a ticket, you need to upgrade later, and then one might not be available. I've even paid the upgrade and had them refund it when they overbooked the Economy Plus section. And since the normal seats are too small, that's just miserable.

So yes, a decrease in comfort has caused me to boycott an airline. But maybe they just want shorter people anyway since they'll weigh less.
Hell of email applications on iPhone
Pdroid is fantastic. I waste time patching my ROM every time I need to upgrade with that tool. The amount of information you can disable or manipulate to hand to app providers is amazing.

I think Android would have much better cred in the geek community if this was standard, but the legal and business hoops it jumps around and out of make it a pipe dream. I will say when I meet Infosec guys in my area and show them that app, even the iPhone guys are impressed and want to know how to get it if they got Android phones.
Rare sensible comment in this thread. Anything higher than a Bachelors online is self-defeating until widespread group chat at least minimizes the blow of no professors. Maybe one day with a partnership with Oculus Rift lol
I would argue that any successful small business that could be considered a startup is growing some metric much faster than 5-7% per year. Likely somewhere close to the per week rate. You just have to pick the right metric. What you're referring to is likely a 5-7% growth in revenue per year, and that can be surprisingly good. There are probably "successful" YC companies that aren't growing their revenue that quickly for the first couple years. But some other KPI is going crazy.
The recent post about stepping over the homeless is probably SF most worrying problem - if the tolerance that SF is famous for is at play in SV success (and I do agree its causation not just correlation) then developing an enclave mentality will mean SV will revert to its own mean irrespective of the surrounding town.

I am not sure about lz4, but gzip in my cassandra experience is significantly reducing performance, Db needs spend too much CPU on compression. Snappy works just fine.
I think the key question then is why it was that 4.8 more seats were filled on average per flight. If we had data the showed that the distribution of plane occupancy were the same year over year save for a few occasions where last year the plane had been at capacity but this year those extra 6 seats had been put to use then the conclusion could be valid. However with the data I've seen so far it seems spurious to conclude that the extra 4.8 filled seats were caused by the extra 6 physical seats.
It's 80% pre inch reduction (N Seats) and 80% post inch reduction (N + 6 Seats) which would average to an extra 4.8 seats per flight.

This is my thinking as well. I had my entire business shutdown on Amazon a couple of years ago. No amount of explaining did anything.

They have automated responses that are made to appear like real people responding to you. They also kept my remaining balance for 90 days. I was lucky that it wasn't my only income stream.

As a buyer, you get all the power on sites like this. I can see why they do this (they want Amazon to be a trustworthy marketplace), but it's unfair to legitimate sellers that get banned because an automated script somehow thinks they are doing something illegal or against the ToS.

Sure, people would pay more to get better treatment but most people don't fly enough to know the difference. Ask a few people around which airlines give you the entire can of coke and which only give you half the can in a tiny plastic cup. Ask them which airlines give out free pretzels on medium length flights and which ones give out a menu where you have to pay for everything. Ask them how expensive the cheese sampler is off that menu and if they remembered to factor it into their cost of better treatment. Which airline has the widest seats? I actually don't know the answer to that. Thinnest stewards/stewardesses? I could care less about how attractive they are, but I like aisle seats and don't want fat stewardess butt in my face when they walk up and down the aisle. Are you going to be flying in a widebody jet or a tiny regional jet? You get the picture. There's lots of stuff to consider, and 1 inch less of legroom may not pop into people's minds (certainly not mine since I am always in an exit row. It's my mini-first class upgrade).

The fact of the matter is that most travelers aren't informed enough to know the difference between airlines except for the prices that show up on Priceline/Travelocity/Kayak/etc. I would like to see a feature chart on each airline and an estimated value to see if it was worth the extra money. I would pay extra to get updated intel like that before I book a flight.

It's funny... the UX person in me was thinking it would be easier just to take a picture of your shopping cart and have it highlight the items you shouldn't purchase. Just based on packaging. Then I thought ... hey ... an even better idea would be to hold the phone up in front of the shelves and have all of the offending items X'd out.

Then I thought ... man ... all of this would be a LOT easier if Google Glass had a better camera! Maybe Apple will make a better pair of glasses and in the not too distant future we can just walk up the aisles and have all the products we wouldn't want to support X'd out for us.

Point is... in the future you will most likely not have to scan the bar code. The software will just put X'es over all of the products that are "bad" by some definition set by you. That would be a pretty interesting use of something like Glass I think.
