Ouch. That hurts. You have taken such a small part of what I have said and used it to paint me as someone who is taking advantage of the fact that Uber offers cheaper fares than a taxi service. And then to add salt to injury, you throw in that last line. While I agree somewhat with your point, your comment was just plain rude. There are so many other ways you could have said what you wanted to say without launching a borderline personal attack on me and trying to paint me as this horrible person.

Everyone can claim to be ethical, but at the end of the day whether you realise it or not, you're supporting people in not only your own country but other countries through the purchases you make everyday, not necessarily in the best way either. That $5 coffee you might purchase every morning is benefiting people picking coffee in coffee producing areas of the world. Those same people are getting paid horribly, they're also subjected to abusive work conditions bordering on fear tactics used to keep them working. You're helping people support families, but it is a catch-22, you're also not making things better either. So lets not get all self-righteous about this. Taking an Uber is no different than deciding to buy that new TV or pair of shoes.

That iPhone or Android device you probably own was made of components mostly manufactured in China at the lowest possible price to maximise the profits of a large corporation. The same thing, people working in those factories earning a few dollars per day (way below the poverty line) because they have no choice. The MacBook Pro or desktop computer is also made up of components built and assembled by people working in deplorable conditions for cents on the dollar.

At the end of the day Uber is a job. And while I do not agree with how Uber operates as a company or their misleading advertisements to get drivers, no matter if you're choosing to take an Uber or a taxi, you're putting money into someone's pockets. It might not be the best way to help someone, but at the same time there are a lot worse jobs out there in the US and other parts of the world where working conditions are dangerous, the money is even lower and the hours longer. At least with Uber you choose your own hours, how much you work is up to you.
The entire economic system is built around people trying to get the best deal possible for themselves. You can try and paint that as inhumane and abusive...

Wow -- you're so damn close to the moment of insight, and yet so far.
I actually commented on this exact possibility on the original post about his prosecution [1]. The answer to the headline is yes, they can form cartels, and if they were smart enough, the algorithms would figure it out on their own without any human intervention that this is the most profitable way to do business. There is currently no API for bots to check with to see if they are violating the law, and it's unlikely that the author of an algorithm that ultimately decides on its own to take actions that would probably violate the law if performed by a human would be held accountable for its actions.

Note, updatetable columnstore sucks everywhere, so I don't think so. It's only for OLAP, not OLTP (parse is oltp).

What may help @azinman is group-compression (ex: bigger pages of rows and compress the whole page, where each json-key can be repeated multiple times in a page since each page may have multiple rows). This is what happens on tokudb,hbse,hypertable,cassandra.

Translated: "That same energy could have been spent on something I care about and not what the author cares about."

Which kind of explains why communism always leads to tyranny: it is based on the essentially tyrannical assumption that communists alone have the knowledge to decide how everyone else should be spending thier time, and the moral authority to impose that judgement on others by force.

The problem is that no one has ever found a way of granting such power of central decision making in such a way that either:

a) central planners have access to the information and computing power distributed in the market such that they can make well-judged decisions even by the theoretically pure criteria they claim to be using (that is, communism is inefficient)

b) central planners have no incentive not to make decisions that serve their own interests to the detriment of all others (that is, communism is corrupt).

Given that theses results are incredibly robust and widely known, it is weird that anyone would suggest communism is an interesting alternative to anything. Reform capitalism all you want, but why bring up the political equivalent of a perpetual motion machine as the solution?
Ask HN: Why doesn't hn have a notification mechanism?
//Half rant, half ask hn...please forgive.

Why doesn't hn have a notification mechanism equivalent to reddit's orange-red?

When someone posts something sensible in response to one of my comments on (any) social platform then I'd like to know about it so that I can thank them/respond/decide to ignore.

hn does not do this - worse...recently responding to old comments was disabled.

Now I appreciate hn's minimalistic design and that they don't bug me with adverts and random ad notifications...but this just seems broken when viewed in terms of the forum's broader purpose of facilitating dialog...

Take 100 random people from your mall on a saturday-- so just regular people-- how many of them do you think are using gold and silver on a daily basis?

IF you answered anything less than 100 you're wrong.

First off, how many of them have jewelry? A great deal of them do. Not just necklaces and earrings, but wedding rings. Almost all of them have both gold and silver. How about college students? Their high school ring has both gold and silver too.

How many have cellphones? Both metals are intrinsic in electronics manufacture.

How many use cars? There you get too more monetary metals of even less familiarity-- platinum and palladium are essential for catalytic converters (they use whichever is cheapest at the time.)

Finally the fact of the matter is, the use of gold and silver as currency is a perfectly legitimate, economic use. It is demand in itself. You don't need some other industrial use to justify its use as money.

Because in all of history, no superior money has been found.

People use paper currency because of Gresham's law, so long as they can, they will spend it. But people who collect wealth who have a longer view will have some of it in precious metals.
It's also a silo that can be hard to get out of and is very hard to get into, because all you do is C or C++ work and everyone wants C or C++ experts for their jobs.

I had a fiddle with some Estimotes for a research project last year. Managed to get some fairly inaccurate indoor location tracking going on Android using 4 beacons and some fudged trilateration functions, then did some cool location-based things with Philips Hue bulbs. Was a blast!

Keep up the good work, can't wait for the Android Indoor SDK! (I appreciate that it's more effort due to differences in device hardware, etc)
Uber has enough market power that it's often a monopsony, and thus has the power to depress wages more than would happen in a market that didn't have the winner take all dynamics of most app-based businesses.

You can paint it as "natural" for a monopsony buyer to squeeze every possible penny for themselves, but most humans have an emotional reaction to interactions which are perceived as unfair. This isn't irrational or dumb. It's natural and it's part of being a human.
"My reasoning for this was I am paying like half the cost of what a taxi would cost me, so why not 5 stars?"

That's true for everyone using Uber. You're not supposed to rate it relative to a taxi, but relative to other Uber drivers.
> it will be cheaper to rewrite the software for the render pipeline.

You don't even have to rewrite it, Linux imagemagick + OpenCV can handle the use cases of cropping and sizing trivially. They can keep the rest of the code (device mappings and CDN related I guess) unless that was implemented using ObjectiveC (this is another thing that I would think is crazy)

Your argument is completely irrelevant. The "its voluntary" thing means absolutely nothing.
So how much does commercial insurance cost? And since you have experience maybe you can answer this: What if you accept the insurance argument that having the app open is commercial, and shut it off to find a parking space after every ride. How long would that take, is it feasible?
Doesn't mean they aren't shafting their drivers.

columnstore is supposed to not work with indices (although they have different types like zone-maps)

each column is stored separately on disk, so only the requested column-values are read from disk

This makes slow to select/update/delete a single row(oltp) since it needs to fetch multiple pages (for each column).
And makes it fast to do queries regarding data in big size (olap) by doing vectorized query execution and sequential-reads on disk
"Likewise, it's not Uber or anyone else's job or responsibility to guarantee anyone or anybody a certain standard of living."

Actually, since Uber is the one giving them a job, it IS their responsibility.
You're neglecting to consider that other employment opportunities for someone in a given set of circumstances may offer a similarly raw deal, which results in effective exploitation, even if Uber is not solely responsible.

Worse than that, Uber externalizes the cost of commercial vehicle insurance onto the driver. A part-time driver is likely to not carry commercial insurance, due to the expense and to hyperbolic discounting: I'd rather have $X more in my pocket now than protection from a possible lawsuit later. This results in cheap fares at increased personal risk to the driver, who often doesn't fully understand that risk.

Also, these drivers have no ability to negotiate as a group, so they are at a disadvantage against a well-funded corporation that is quickly gaining market power and sets all of these terms.
You sound pretty confident in it, so here's a question from a perspective more relevant to the discussion:

Would you found a company and make your primary product hackintosh servers? Are you willing to stand behind your 'perfect' configuration and give those customers years of support?

True, but that's talking about genetic algorithms, not genetic programming. I'm oversimplifying, but GA involves evolving parameters in a system to find a solution, where GP involves evolving the code itself.

I'd contend that the "signal when permitted" minigame makes Jeopardy! more difficult, too, because the part of your brain that arrives at the answer must yield to the part of your brain that tenses for a stimulus. I definitely have to switch "modes" between pulling up deeply buried knowledge and rapid reaction "stance", and I noticed this when I played a well-made copy of the show's rules complete with the signaling system.

There's another side, too, which is if folks could signal early, reading fast would become an even stronger optimization. It already is, but at least everybody gets an equal chance the way it is (even if they got the answer fairly quickly from reading the clue while ignoring Trebek).
No one gets gratification from bringing in a new generation?
If you're rushing to pick up a passenger you have insurance from Uber. (I looked that up to make sure after making the above comment.)

Rushing to a hot spot seems like a flawed argument, you can do that while totally off the grid. App closed, phone off. That's probably going to get you more money, too.

You could have four of these apps open at once, do you need quadruple insurance?

The app requires no interaction, and you perform no actions for the app until it notifies you about a pickup and Uber's insurance kicks in.
Again, your point has absolutely no basis in reality. The idea that there is no exploitation is completely false.
Human labor is not a commodity.

This was the common sense amongst all working people for most of the 20th century. Samuel Gompers, maybe the most conservative labor leader of his time, said "You cannot weigh the human soul on the same scales as piece of pork." And working people, along with the management class for the most part, understood this to be an undeniable truth. In fact, this piece of common sense was enshrined into US law with the Clayton Act of 1914, which stated "The labor of a human being is not a commodity or article of commerce." But in the last 20 years, as capital has gained the firm upper hand, the common sense understanding has shifted towards the idea that labor is in fact a commodity.

The ideas behind the so-called "on-demand workforce" further solidify the notion that labor is a commodity. After all, you can order an uber ride just as easily as you can order vitamins online.

It's so pervasive that even I, someone born into a union family and a firm believer in the idea of worker solidarity, have to force myself to believe that labor is not a commodity. Why? The business class treated labor as expendable in 1915, just as they do in 2015. Why did working people understand this truth in 1915 but not today? I don't know.

I read a recently released sociology book earlier this year (going crazy looking for the title/author, can't find it), that posits millennials are far more likely than any recent generation to blame themselves for the problems they face. It's part of the reason that the self-help industry is bigger business than it's ever been. It's not always your fault. Our modern economy is built on rotten ideas like labor = commodity. If we want to do something about inequality, it's time that we subject fundamentally unjust ideas like these to a serious critique.
Cropping and sizing are just two (common) operations that imgix can perform. There's a lot of other stuff as well: http://www.imgix.com/docs/reference

Not to say that it's totally impossible to do these types of operations on ImageMagick, but it wouldn't work nearly as well as our current solution does. ImageMagick is a shockingly awful tool for use in server-land for a variety of reasons, some of which are handled better in GraphicsMagick. IM was the bane of my existence at more than one previous company.

I also find this list fascinating, but I also agree with other commenters that energy is better spent educating people on these psychological pitfalls than to try to take advantage of them. If "do no evil" was ever a motto that a company believed in this would certainly qualify.

>Why pay 5-10X as much to host on AWS?

You have no idea what the comparison is, and I don't either. But again, the criticisim is around running a business off of a bunch of Apple "trash cans".

>advocating vendor lockin to windows.

Linux is no lockin, Windows lockin via software vs. Apple for hardware and software.

>"vendor lockin" to that platform

Java, Scala,or any other JVM language protects from that, and to a lesser degree Python, PHP does as well.

>There is little risk being "locked in" to the largest most successful company in the world.

Price gauging? Deciding not to support your platform anymore? Forcing you to upgrade?

>Build on Linux and you're locked into just Linux, unless you port.

Only that there are a bunch of Linux options to choose from, they are all open source so you can do whatever you want as far as upgrade paths and support, and if you use the JVM languages this isn't an issue.

>in fact I think one Mac Pro probably replaces 4 or 5 Linux boxes doing this.

There is no fact there, that's your delusional opinion.

>If you think Optimized OpenGL shaders would do this, you're not understanding what it is that they are doing. You're just assuming it's a trivial problem, it is not.

As I understand it, Estimote's main technical selling point is that it uses Bluetooth LE. So the "beacons" can be made cheap and low-power, plus you get out-of-the-box compatibility with modern smartphones.

As you say, the problem is that, in an oligopoly, raising prices is often game theoretically optimal. And while explicit collusion may be illegal, implicit collusion (all parties noticing the best strategy independently) currently isn't. I don't see that computers add much of an interesting angle, except, as the article states, to make irrational or accidental defection less likely.

So really the law on this has always been pretty broken in theory, but maybe it worked well enough in practice. With computers that may change and the law will adapt to some other broken-in-theory system that works just well enough in practice.
No one I know would be interesting in accepting someone else's jewelry/gold/diamonds/platinum/silver in exchange for their food at the super market or a day's worth of work.

The goal of a currency backed by a standard is to give it a predictable and concrete exchange value. Things susceptible to speculative price fluctuations would be less then ideal.

There is a self fulfilling prophecy for people who "believe" in gold and diamonds that attribute a higher value to it than the practical value or worth in industrial applications.

requires us to believe some rather surprising things about the subjective mental states of the many, many Uber drivers

Only if you believe that humans are the sort of simplified perfectly-informed stimulus-response mechanoids (and operating in a simplified-rules environment) that game theory requires. There's nothing surprising here; it's actually pretty mundane.
You're oversimplifying the issue here. The point is that Affirm is apparently using an amalgamation of potentially thousands of data points to make decisions about creditworthiness. Some of these data points, including name, email and mobile number, as well as behavioral factors, could very well prove to be proxies for characteristics which the law prohibits lenders from using to make credit decisions.
Fascinating, I had no idea Apple approves using the Mac Pros on their side. It would be interesting to find out what happens with the fans.

It's also fascinating that they are running Linux internally nowadays, for their server side stuff. What next, I find out that all of the Microsoft data centers run Debian :) Considering that they employ all of those Objective-C and Swift engineers, you would thing that they would want to leverage their workforce write Obj-C or Swift backend code as well. For most backend tasks either Swift or Obj-C is as good of a language as any other.

Any way, rackable OS X systems are a missed opportunity for Apple. They can sell them to a company like yours, movie production houses, and even design some libraries and make a play for the web app market with Swift. Not sure how successful the last one would be. As for the economies of scale, they don't even need to manufacture or design the system, take an off the shelf rack mount server from another manufacturer, fiddle around with the casing a bit to give it that Apple feel, and load OSX on it. Perhaps the margins in the server side hardware are way too slim.
We don't think developers should have to reinvent the wheel, or cobble things together to build a customized experience.
