statistics - 1 vs 1 vote: calculate ratings (Flickchart.com) -

-

Instead of items rated from grades 1 to 10, I would like to versus 1 versus 1 "fight" Items are displayed and you choose the one you like most. Based on these "fight" results, each algorithm should calculate the ratings of an algorithm.

You can see this approach that movies have been rated using this approach.

It looks like:

As you can see, if they win "fight" the items are pushing upwards. Rankings are always " The battle "varies depending on the outcome, but it is not based on the winning quote (54% here) because it is difficult to win against" Titanic "compared to" 25th hour "or more.

There are some things that are quite unclear to me: - How is the rating calculated? Which film is set at the first place in the rankings, how do you decide? You have to consider how often the item wins and how well the beaten items are - what is to choose what is "fight"?

Of course, you can not tell me that Flickchart actually does all this but maybe you can tell me how it can be done. thank you in advanced!

It can not be precisely what Flickchart is doing, but using a different type Algorithms can be used in chess (and other games) because they are essentially fights / games that they win / lose.

Actually, all movies start with 0 wins / losses and win each time get certain points, usually you will have approximately 20 (but any number) and a movie Winning will win with the same rating. 20. Winning against a bad film will earn about 10 points, while a better movie gives you 30 points. On the other hand, losing only 10 points while losing a good movie, but if you lose to a bad movie, then you will get 30 Lose points

Specification of algorithm is in the Wikipedia link.

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.

jquery - SimpleModal Confirm fails to submit form -

-
I am trying to confirm jQuery to show yes / no confirmation when I submit a form. I had modified (in the last list) to capture and block form submissions. However, it only works with jQuery 1.2.6, a recent upgrade stops 1.3.2, if yes is clicked, then by submitting the form. But I can not understand what is wrong / inconsistent in my code now. Demo (which works in both versions of a simple window.href implementation). $ (document) .ready (function () {$ ('input.delete'). Click (function (e) {e.preventDefault (); var target = $ (e .target); Confirm ("Really delete this event?", Function () {target.click ()});});}); How about something like this? The idea of ​​catching clicks (and fire!) On the submitted event is not click event. $ (document) .ready (function () {$ ('# myForm'). Submit (function () {var f = this; Confirm (" Remove? ", Function () {$ (f). Submit ();}) Return; Return the initial session;}}}}; Hope That this is som
