MySQL is SELECT with LIKE expensive? -

-

The following question is about the speed between choosing an exact match (example: INT)

What's the difference? The main reason I am asking this is because I am trying to decide whether to leave the ID out of the current project is a good idea.

For example: 

  http://mysite.com/article/391239/this-is-an-entry  

  http: // mysite com / article / this-is-an-entry

Do you think I have long time Will I experience any performance issues? Should I keep the ID?

Note:

I would like to keep users to keep it easy to remember. For example, if they write they will be redirected to the right.

About the number of pages, to say that I am approximately 79,230 and the app is growing fast as if 1640 entries per day are called

An INT comparison string will be faster than comparison (varchar) comparison, similar comparison is slow because it includes at least one wildcard.

Whether it is important in your application or not, it is difficult to tell what you told us. Unless it is really intense, i.e. You are gifting these comparisons, I want to know clearly for your users.

To think of another thing: is the user always going to type URLs? Or are they just going to use a search engine? These days I simply search instead of just trying and remembering the URL. This would be a non-issue for me as a user. What do you like the user? Can you tell from your application how they use your site?

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
