Your right. There will be a huge latency spike when the out list needs to be refilled.

My throughput benchmark does take this into account though. It attempts to add 100,000 events to a window that only keeps events for 10 seconds. Adding 100,000 events takes much longer than 10 seconds, so the out list will be repopulated a couple times before the test is complete. The throughput benchmark is only an average though... And a longer running throughput test would yield a more accurate average.

I will update the post with this information.

> Microsoft user experience sucks as is on either platforms, continuum is not going to improve on that.

I'm pretty wary of Windows 10 Mobile (is that the right nomenclature?) but Windows Phone 8.1 is fantastic and I think probably the best user experience available on mobile. It is certainly at least comparable to iOS and Android. I most recently came from Android, switching from a Galaxy S3 to a Nokia Icon, and the Windows Phone is much more of a pleasure to use, in my experience.

My only real substantive complaint is that there aren't enough official apps (e.g. no Snapchat) and the ones that do exist are often obviously the ignored stepchild for the developer. I can see how the ideal of Continuum would be nice, but on the other hand, I suspect they're going to mess up a good thing.

If you haven't used Windows on mobile since the garbage that was Windows Mobile, or the halfway-there Windows Phone 7, then it's worth looking at again. But that's also part of Microsoft's problems: they fumbled so often on mobile and people haven't forgotten.

Problem with PayPal is that they ban people (I lost my account years back, still do not know why) and also of course not available in all countries.

I was thinking something along the lines of some sort of new HTML "payment" tag so it could signal to the browser things such as "product details, price, available/preferred merchant payment method"

and then the browser would pay from an in browser wallet containing stored credit card numbers, or bitcoins or prepaid/voucher codes, or bank account information

Some browsers could outsource this by starting a separate wallet program altogether, sort of how some links on mobiles open up other apps like maps

Someone above mentioned bitcoin links, that be a very good example of how to do UI payment flow nicely, especially nowadays that

I posted this comment on another taxi medallion article, but figure it's hopefully more relevant here:

Just a little background on medallion finance:

A few summers ago, I worked in commercial credit and we did a financing for a "taxi mogul." He was replacing several cars in his fleet, and wanted to take out term loans for the full purchase price of the cars (approx. $30k each, IIRC).

The loans would be secured by cash flow, but the business also posted medallions as collateral. Each loan was attributed to the vehicle purchased with the proceeds and secured by that vehicle's medallion.

It's hard to value something like a taxi medallion. Medallions aren't liquid -- they are usually sold in very low volumes at auctions controlled by the TLC (in NYC). Additionally, the TLC limits the number of outstanding medallions. In practice, most of the medallions are concentrated in the hands of "taxi moguls" who started taxi businesses in the early 20th century when medallions were cheap (think $30k). The best approximation for value we had was the prices commanded by medallions at auction. When I was doing diligence on this deal a few years ago (before Uber), prices were accepted as $1.1mm per medallion. (In reality, that was at best the value of the "marginal" medallion sold; i.e. you could probably not put 10 medallions up for auction at $11mm.)

That means that a $30k term loan would have a loan-to-value of about 3% -- a dream for a bank, assuming the medallions can be seized and sold at market value upon default. That also meant that the loans would be approved almost regardless of the integrity of cash flow. Those characteristics allowed the more cunning taxi moguls to borrow a lot of money against their medallions, securing low rates due to the strength of their collateral posting, and lend the money out at higher rates to earn arbitrage.

There was a good amount of discussion about the medallion bubble -- all it would take is a significant increase in the number of medallions authorized by the TLC or a few failed auctions, and a medallion sold at a large haircut, for the value of all medallions to plummet. Granted, the drop in value might not trip loan covenants, but it would significantly erode the balance sheets of these businesses. At the time, we didn't expect that there would be an external force that would hurt medallion values.

Honestly, skyrocketing medallion prices made it clear that additional ride capacity was needed/demanded. The interesting fact is that the medallion market wasn't disrupted by the issuance of additional medallions, but rather a drop in the demand for yellow cab rides -- a scenario that taxi moguls likely hadn't planned for.

All in all, an interesting asset class that most people aren't aware of -- those 4-letter signs on taxis hold no meaning to riders, and almost nobody on the street would guess that they represent assets worth over one million dollars.

As I see CIE LAB is not a something "inferior model" to these more complicated models. It just has a more simple viewing conditions model and a more limited regime of validity.

It seems somewhat complicated to properly apply CIECAM02. In the case of matplotlib, one should change the line colors depending on the background color being used. Not talking about adapted whitepoint and surrounding too where you at best can make an educated guess. They seem to solve the Euclidean distance problem by embedding in a field with more dimensions.

However I'm really happy for these efforts of matplotlib. It is by far my favorite data visualization library. There could be cases where this kind of accuracy is necessary: doctors often diagnose using visual inspection of different camera images (X-Ray, CT, MR). The optimal visualization of these camera images using well crafted colormaps in the right colorspace could save lives.
Great suggestion---I recant my original comment and second this.

Wow AD-36 is interesting! I never knew that. I'm curious if we could give it to people having trouble gaining weight?
Good question!
As you already hinted, we will not disclose all our security measures.
But our platform is secured on multiple levels.
First of all, all communication between you and our server is encrypted. No eaves-dropping possible. So only you known your own vurnabilities.
Second because you have to verify your server, a thirdy party can't get secret vurnability data about your system. So they cannot use our system as easy tool to get attack vectors.
Third we separate the scan logic and webserver logic into different servers. And only the scanner has information about passwords and secret information. So while we make our webserver very safe, the scan server is fort knox. One particular nice thing, the scanner server has no open incoming ports. So you cannot access it.
Fourth the PHP dectector file will only react to our server and all data exchange is encrypted with keys only known to the scan server. The commands that have to be executed are also signed with assymetric keys, signed on an offline computer.
Fifth we keep improving our security while monitoring our systems (with our service but also with other tools). Because new attack vectors are released everyday.

kinda extreme. Most of them probably go there for employment opportunity, nothing to do with whatever ideology. Calling them names just sound so immature and unprofessional at best.
As opposed to most other text input fields you encounter in the wild, credit cards (and phone numbers) have a singular canonical format. As long as you don't limit HOW it's entered (or pasted), it makes a lot of sense to coerce the input into the canonical format.
Interesting. On following up on your links, I see that while optical pumping was invented first, Townes was able to make the first maser by using an electric field to separate out an excited state of ammonia, achieving a population inversion without pumping. http://home.fnal.gov/~kubik/FermilabWebsiteDocs/Masers.ppt

The closer you look, the less the history of innovation looks like a simple sequence.
Thanks you make a distinction and the pics really drive home your point. I guess the problem is the label 'true color' which has stuck for a long time to a refer to statistically determined hues. Maybe we should label 'actual true colors' as 'real color' in order to make the distinction. I suppose true color started out as a way to distinguish them from artistically rendered/painted images.
I think the machine learning aspect is the wrong choice here. I'm seeing another glaring answer, and one that can be done fairly quickly: Integral analysis.

The servers that have error accumulation aren't always the ones highest in spikes, as shown in the link. However, they do consistently stay above others in amounts of errors. So the answer is thus:

Since your time series is quantized, the integral is simply a sum over the timeframe. I would recommend multiple time windows, like "10 seconds, 3 minutes, 1 hour, 12 hours". Do this for all your servers.

Now, you have a normalized 2d graph, with respect for time. We can now calculate the mean of all servers' error areas as well as standard deviation. Now, for reducing CPU load, one can run a modified thompson tau test on +/-2σ for outlier detection. 4σ is around 97.7% of all your data, so you would only be checking ~2.3% of your data.

When a server fails an outlier test (in other words, is detected as an outlier), the historical data can also be investigated. Is the machine doing gradually worse? If so, the machine could be removed from service until a memory and CPU test can be run. You can also keep anomaly detection on how many outliers per hour. Passing a threshold could indicate potentially erroneous machines.

My answer also assumes that the machines are equal in the amount of load. I'm sure this is not the case, in which you will have to normalize errors/# of requests. This shouldn't be a problem.
This is a hugely important point, and couched as it is in somewhat difficult terminology it may not reach the audience it should.

Polemicists have the job of explaining meaning to others while persuading them. I will show you various pieces of data supporting my thesis and my thesis will give you understanding of how and why things work. If you write an opinion column, this is your job.

This is not the same at all as trying to minimize assumptions and simply show relationships.
Watching economists claim to be amoral is amusing when they so transparently have moral beliefs they refuse to acknowledge.

Valuing unregulated markets over other priorities is a moral philosophy, one that is meaningless since there is no such thing as a completely free market. Claiming you know what the result of a huge national policy like raising the minimum wage based on the extremely limited data of the field is disingenuous, at best.

Krugman is interesting because he appears to have given up on the amorality angle. This does not make him a traitor to the field, this simply acknowledges that the field is not impartial.

The questions that economists should answer in a political context is not "why is regulation bad/good?" but instead "What is the best policy given that my values are x,y,z?"
Thank you Jacques, if I'll visit NYC, or you Sicily, you have a paid beer for the message queues hints, and for sure a visit from me in the Pivotal offices :-)
Do we have a comparison of how much is lost to fraud otherwise, without bitcoins?

Anecdotally, the only time I have ever been defrauded of money was when my debit card was skimmed. The fraudsters kept trying to withdraw money, which I didn't keep in that account as I immediately took it elsewhere. It was the account in which I received my paycheque. The fraudsters were able to steal one of my paycheques, and the bank was completely ineffective in protecting me. I got no warnings of unusual activity, and I got no money back. I should have gotten some sort of warning, since someone was repeatedly trying to withdraw money from unusual locations from my empty account. Even my account history showed nothing. Not until I asked the bank after the money was already gone did I learn that the fraudsters had been attempting every day to withdraw the money.

How many stories like mine are there compared to bitcoin stories?
We use multiple companies, all of which are "something like Stripe", to avoid dealing with PCI requirements. I've never seen any of them check zip or name, if you want added security you ask for 3D Secure/Verified by VISA. That will either require the customer to login via their online banking solution of enter the code sent to them via SMS.

On of our payment providers just told us today that by August 1st. 3D Secure will be required for all online transaction in the EU. It might be later, less than one month doesn't seem like a reasonable notice.

Honestly name and zip seems like something that's easily obtained by a scammer.

The pretext of the discussion of what sorts of downvotes are okay is that someone is watching and is going to do something about it.

That seems like it might happen in egregious cases, but I'm not sure why people think someone is going to spend a couple of minutes analyzing whether the 4 down clicks on their tossaway comment were fair minded (whatever that means) or not.

So the problem isn't just that it's a boring discussion, it's also just not a reasonable expectation that every single click be fair (whatever that means).

Its generational.

The first generation of the web was its short simple text, and it has URL links. You need a language for short simple text reports. In the 90s, that was Perl, it probably still is today.

Several generations of the web have happened since then, the graphics art generation came and went (the web should be programmed entirely in WYSIWYG frontpage or the web should be nothing but downloaded adobe flash animations) and now we're into the program generation (the web should be cascading classes and object oriented frameworks and infinitely complicated architectures)

I think you can wedge a simple text reporting language into the later generations but its going to be more difficult than using that language to generate simple text reports that happen to have some html entities sprinkled in.

MOOSE is a pretty awesome OO system for perl, and Mojolicious is pretty good, but its not realistic to dethrone RoR or javascript frameworks with Perl.

Perl6 could be positioned for the next generation of the web, whatever that ends up being, after the programming generation.

Most production COBOL programs run on IBM compatible mainframes so you'd also need to get a handle on developing in MVS aka "z/OS" and how to hack JCL config scripts--the horror! That's difficult to do without getting hands-on experience.

As someone whose first job out of uni almost 20 years ago was in a mainframe environment, I have no desire whatsoever to go back to it and would strongly recommend against working in COBOL if you can make a living using tech that was developed in the last 40 years.
For postal codes, they're even doing the right thing for the wrong reason. They believe they're only going to encounter US or Canadian postal codes. Billing addresses can be anywhere, of course.
My understanding of CIELAB is that it tries to approximate perceptual uniformity while also having a rather simple transformation formula. As such the perceptual uniformity is compromised (intentionally). It is a good approximation but the lack of uniformity can be noticeable -- particularly in the hue dimension. See my 3rd link.
