Brokers are needed if you want queues to persistent across consumers. ZeroMQ is a multicast system; if no listener are running when an event is produced, the event is thrown away. Great for real-time RPC, not great for a task-scheduling system.

That's already more or less the case with Windows 8/8.1.

Although there are contrived ways around it, generally speaking you'll need a "Live" account to login and that also hooks up your "OneDrive" and so on.
Which other incentives?
I've been going through the demos that Google provides on the Cardboard site and it's pretty incredible. There were some fleeting moments of forgetting what I was doing. If you can get the side light blocked out, get it comfortable on your face, let go with your hands, and just relax, it feels like you're standing in a completely different room.

Input is nigh impossible. They have a magnetic clicker in their design. I reach under the bottom of mine and tap the screen. It's kind of weird to see a super large finger come in and poke at an invisible glass wall between me and the thing I'm trying to touch. Regardless, I don't think I'd like the clicker. Touching the contraption cements it into reality. The best effect for me came from letting go. Voice commands coupled with radial heads-up menus are probably the best bet. Perhaps nod-to-confirm, shake-to-cancel could be implemented.

The demos that had flat wall surfaces seemed the most convincing. There was a tour of Versailles that at first seemed really bad, while it was still outdoors. Once it got indoors, the photo quality didn't actually improve at all, but the notion of the walls really helped sell it. I stood in front of a painting of Marie Antoinette and surprised myself when I tried to step closer, only to bump into a table in meatspace.

There was a demo of YouTube where it simulated a large screen TV in front of you, and you peered around the TV to select the video, like they were on shelves 360 degrees around you. That one also worked really well, other than being stuck with someone else's selection of videos, it really felt like sitting in front of a big TV in a very dark room.

A video from a helicopter flying over the Great Barrier Reef further supported my experience that constrained rooms are better.

There were some other things, but not a lot to write home about. I'm surprised there aren't any telepresence demos yet.
Alright, thanks a lot for the explanation then! Then my concept wasn't entirely wrong.

Price Gouging and the Poor - relevant

Man claims he was kidnapped by Uber driver in DC
Think I posted it.

MMM is like religion... take 10% of it to heart and you'll likely find something of use... throw the other 90% out.
But there is a point in incentivizing a larger percentage of the total number of drivers in a given area into accepting rides during 1-2 hour surges.
I always enjoy Nathan Barry's writing and his work provides a pretty good template to reverse engineer a lot of good ideas, similar to what Patrick McKenzie does as well.
>> most servers don't make a new process for every request anymore

That's correct. Most designs use either a prefork model (e.g. Apache) or an asynchronous event-driven model (e.g. Nginx). With prefork, a number of worker threads or processes are created on start up, and each services one request at a time. In the asynchronous model, a smaller number of (typically single-threaded) processes are created on start up, and each services one event at a time. An event could be an incoming request, a database query returning, etc. In either model, thread/process creation typically happens entirely on start up.

On the other hand, the limit on taxi medallions protects a common resource, room on the streets. Maybe the balance isn't right, but you're going to need some artificial limitation or else you're going to have a classic tragedy of the commons.
> it skews heavily towards the wealthier

I'd say it skews heavily toward those with the greatest demand, as the previous post said.

If you have average financial resources and needed to get to the hospital in the middle of a snowstorm, you stood a better chance under Uber's previous model that allowed a market-clearing price. Now that some NY politicians have outlawed that process, the price that they permit will be below the market-clearing price and the likelihood of shortages will increase. Put another way, Uber drivers will (sensibly) venture out in snowstorms only if they can make significant $$$.

Hope you're well enough to walk to that hospital! Thanks, Albany!

(Note I'm not an interested party here: I own a late-model car, I don't live in NYC, and I've used Uber and similar services < 5 times this year. But someone was wrong on the Internet and clearly needed to be corrected.) :)
Awesome. Possibly the best hack I've ever read.

(Sure, I'm a security guy, and part of me agrees with some of the other comments. Sure, I'm a tech geek, and I've seen and read about some wicked cool hardhacks, unexpected softhacks, and their ilk, and even some good life hacks. But this is awesome. An arguably silly security policy sought to control a small aspect of his work-life and he gamed the spit out of it to take total control of his life, change things up, get stuff done. Best hack ever.)
You're probably asnwering my other comment? Thanks for the info anyway.
The amount of economic ignorance on display in here is not only astounding but deeply depressing.
I sympathize with the resentment of those who got unfair advantages from exploiting others, but preventing goods from being economized based on price signals entirely is not the right response.

From the fact that some wealth is unjustly acquired, it doesn't follow that we should expect everything to cost the same and be allocated by queuing.
Very cute story!
One of the stated reasons. We've yet to see any evidence that this effect actually occurs and is significant.

This is the same company that tried to eliminate its competition by ordering cars and canceling them at the last moment. I like their product enough, but their business practice track record suggests that they are not on the up and up.

Particularly in NYC where surge isn't just long events like New Year's - surge kicks in during half hour rainstorms as well. I highly doubt there's any significant supply change in that kind of time frame - in which case Uber is simply price gouging without any of the claimed positive supply effect.
Because when demand rises due to certain events or circumstances, potential drivers are also often part of that.

Want more drivers on 4th July do get drunk people home from bars? Guess what - a lot of potential drivers just got shitfaced at bars themselves.
It's not required, but Windows 8.1 pushes you very strongly to log into your Microsoft account, and to create one if you haven't already. If you don't, most of the built-in Metro (er, Modern) apps won't work, including some like Calendar which you'd think shouldn't need it.

Further, if/when you finally break down and sign into your MS account, you have to use it to sign into your computer from then on, instead of using the password you set when you created your local user account. So unfortunately, the scenario you described is pretty much already here for Windows users.
This article misrepresents the facts, and the headline is false in two different ways. (False claim about surge pricing, unsupported claim about "economists")

For the life of me, I don't understand why we don't replace rent control with means-tested cash grants if we really care about displacement (and pay for it out of a Land Value Tax, but that can be an orthogonal issue). The way we have it now, we're screwing arbitrary renters (including poor ones) that happen to move between apts more often, to pay arbitrary renters that happen to move less often (including rich ones). I don't understand how anyone could say it's good policy with a straight face.
Well, those people would probably simple cycle through their passwords, or append an increasing counter. So regular changes do not protect the security, but annoys people that are using generated passwords that are completely unique for each and every service.
No signaling needed other than rsyslog itself.

Sighup is needed when processes (such as Postgres) write directly to log files. These files are open, and when you want to rotate the file, you have to tell the process to close the files so that it will start writing to a new file.

If you tell Postgres to log to rsyslog (or any other syslog daemon), the log data will be sent to rsyslog via UDP, TCP or a Unix socket. Postgres itself will not have any files open, so there is no need to sighup it.

You will have to sighup rsyslog in the host system, though.

Side-note: Apache 2.4 finally has an event-driven mpm. A little late, as nginx rules the web now, but it's still nice to see they finally realized their style didn't scale.
No, that's not the idea. If surge pricing was in effect all the time --- if travel pricing was always an auction and drivers were kept scarce to keep prices up --- then Uber rides would be a service for the rich. But disasters are rare, and the surge multiple is merely the equivalent of several Uber rides instead of one. Meanwhile, the alternative to surge pricing is a high likelihood of not getting a ride at all, because disasters suppress demand. It's hard to see the class-warrior logic in this situation.

(Later, you edited your comment)

It's a caricature to suggest that "Coase" is, to economists, a license to apply the free market to every public policy problem.

Meanwhile: you have to actually make the case that there's a distributional problem with surge pricing for Uber rides. If the alternative is no rides at all, then surge pricing makes some people --- not all of them rich --- better off while making nobody worse off.
>the argument that says medallions are bad public policy because they're monopolistic applies equally to many other forms of licensure, for instance zoning.

True; many of those other forms of licensure are also bad.
Actually, that's what they're becoming with price control: http://www.nytimes.com/2011/07/07/nyregion/more-apartments-a...
The Second Contributor
Modeless is actually in agreement with you, as I understand it. The distinction they're making is a bit of a fine one, but they're basically saying Uber ought to allocate all of the increase from the surge pricing to drivers rather than taking a cut. By not taking a cut Uber would more efficiently incentivize drivers to get out and take rides, and more rapidly affect an increase in supply and the corresponding price rebalancing. This would also have the happy side effect of making surge pricing wholly defensible, since Uber sees no benefit from it.

Whether or not that is feasible under Uber's business model is, of course, a totally different question.

From an economics perspective there was money left on the table an Uber is taking it, and that's the end of it. However, economics will also tell you that this doesn't seem to be an equilibrium situation, and therefore competitors will start entering the market until Uber's profits are razor thin, unless the regulators get in the way and screw the whole pricing scheme up.

The concept of "digital product" is flawed, as it implies scarcity, which is obviously artificial and mostly based on regulation (e.g. copyright law). Instead, you should sell digital services.
That car I would have used stayed available for someone that needed it a lot more than I did.

That car stayed available for someone willing to pay more money. Between two people of roughly equal means, that's a good proxy for "needs it more." Between two people of vastly disparate means it's not.
Excerpt from that survey paper you cited, which reports that economists agree that "rent control is bad":

...I find that the preponderance of the literature points toward the conclusion that rent control introduces inefficiencies in housing markets. Moreover, the literature on the whole does not sustain any plausible redemption in terms of redistribution. The literature on the whole may be fairly said to show that rent control is bad, yet as of 2001, about 140 jurisdictions persist in some form of the intervention...

That will introduce yet another delay/flapping point for people on unreliable connections:

You start with a longpoll and get some data, then negotiate websockets (hey, my network and browsers are websockets capable!). Then the connection drops. And then you go through another round of everything again when you get back online (http + longpoll + websockets, instead of just http + longpoll).

Odds are, your website doesn't need websockets anyway, and 99% of your users are just fine with waiting a couple of seconds more to get their notification (and in the process, people with unreliable connections can still use your site).

Of course, if you're doing online stock trading notifications or something like that, you might actually need these two seconds. But then I'll strongly question your choice of using a browser for that :)

I tried using Box for a similar reason (I needed a way to securely share multiple files and/or folders with external clients in a way that did not require them to install software or sign-up for some service) and it just doesn't work. I also desired a way to automatically upload new content to this platoform.

No dice. After emailing with 6 different Box employees (all ignoring my requests and trying to sell me on shit I didn't ask for, then would just pass me onto someone else) I was finally told that I could only do that if I paid for an enterprise "call for pricing" license.

I have a word list in front of me (2000 "short" and 10,000 "long" lists), "Forgive@h3r" "Quit@smoking4ever" "Save4trip@thailand" and none of his other passwords are listed on it.

The way those passwords are constructed don't make them common enough to appear on most word lists and it would be very difficult for someone (who knows you or not) to guess them.

Now, dates of birth, or other common profile information is commonly misused in passwords and that is guessable. But that isn't what the article was about and wasn't in their examples.

I think the article rebuffs your post before you even posted it. So unless you can explain better how what the author is doing is insecure (and I highly doubt you can) your criticism seems misplaced.
A Supercharging Milestone
> there appear to be common two ways of allocating scarce resources in situations like this: either through price, or...

But the quantity of the resource (Uber drivers) is not fixed. If you allow a higher surge price, you get more drivers.
> There's not a huge difference between "no one getting ice" and "a few rich people getting ice".

The idea behind demand pricing is that people who need it the most will be the most willing to pay; pricing is the only real general mechanism we have to express need/desire. With Uber, I sometimes take Ubers even though my destination is straight down a bus line (to avoid waiting at the bus stop, if the weather is bad, etc). If the price was high enough, I may decide to just take the bus, which means the Uber is freed up for someone taking a trip that's less amenable to purely taking transit.

You are of course right that this effect is distorted by the fact that the wealthier you are, the less valuable money becomes, so you're willing to pay more for things that are less important. It just seemed like you were being a little reductive and ignoring the actual intent (and partial result) of demand pricing.
I think it only makes sense to argue on a case by case basis. Saying one unreasonable practice is ok because there are other unreasonable practices is hardly constructive.

For example there is a fixed limit on available land, therefore it makes sense to regulate its use for the common good. The problem with licensing taxis isn't that they are licensed, it's that the number of licenses is fixed arbitrarily without regard to the actual need for taxis.
I think it's time to reconsider a lot of state licensing regimes. But the fact that they're licensing regimes isn't what makes them bad. Licensing regimes are a perfectly reasonable way for the state to control behavior that involves negative externalities. I think almost everyone agrees that governments shouldn't allow factories to be created in residential areas, or allow drivers to drive without liability insurance.
The problem with this is that the people who get the rides in surge pricing are not the ones with the most demand, but those with the most resources. It's an inherently classist system. The surge price, to that rich person coming out of work to catch a cab to that upscale restaurant for dinner is pennies. But the surge price to the single mother who desperately needs the cab to get to school to pick up her kids on time before the school closes and they have to walk home in the rain with out jackets is breaking the bank.

This does not make things "better for everyone" as the article argues. It only ensures that the wealthy always have it good, instead of having to compete for the limited service with everyone else. And it doesn't give the rides to those who truly need them most.
OK.

That's interesting coming from the Bitcoin angle as I've seen Trezor present before and personally opposed Gavin's stance on both SSL use and the general scope increase in Bitcoin's Payments/Receipts discussions. Deaf ears.
>drivers couldn’t be lured out of their warm beds on a cold and needy night.

This is not only about warm beds, it's about risk and reward. A snowstorm increases the chances of getting into a car crash by many factors, and if the reward (surge pricing) isn't big enough, drivers won't be willing to risk it.
Thank you for bringing facts to a mindless rage party.
Careful: ancaps, hardly an Internet endangered species, definitely don't agree with this.
WebSockets are super easy to use and the proper solution to real time data communication between browser and server.

Yes, there are other ways to accomplish this, but why would you choose a kludgey way like long polling when an elegant solution is available? It makes no sense to me.
Not necessarily a failure. One of the purposes of medallions is to control the number of taxis on the road. It's a conscious choice, and the fallout is accepted in exchange for less taxi congestion.
It is no different than Google in that respect. Tbh, I think Google has more market share for its core products relatively speaking.

That is one of the things that makes tech interesting, you can win really, really big in one area then roll it into other related areas.

Will you email me info pls? david at aisleup.com
So you're saying there is a valid public policy case for limiting the number of taxis, and you just think San Francisco got the number wrong? (For what it's worth: that's what I think too).
Yep. Instead of "expensive Uber rides" during a snowstorm, you get "no Uber rides." (A shortage, in other words.)

Thanks, Albany! Well-done.
In January 2015, Windows 7 moves from "mainstream" to "extended" support. What does that change for you and nearly all other users? Nothing. The only difference from mainstream to extended is that Microsoft won't take requests for new features and changes during extended support. And you won't get free phone support any longer, though paid options are still available.

Windows 7 will continue to be supported in "extended" support with security issues fixed regularly and paid phone/online support until January 2020.
While this is true, what makes taxi medallions so unique is the price discovery. This is one of those rare things where you can see, quite unambiguously, the direct effect of the monopolistic behavior. Other things like zoning tend to be very complex and ambiguous, but taxi medallions are simple. The effect? NYC taxi medallion prices have grown by 29% annually over 30 years. As someone in the investment world, that might be the single best performing asset class I can think of, all for the privilege of taking someone from point A to point B. I noticed airlines don't need medallions - how has that worked out?
