Database versioning -

-

I have created some projects (CMS and EC systems), which must have some data version.

Usually I come with that type of schema 

  + -------------- + + + Fobar + --- --------- + + + foobar_id version + + -------------- +

It did great work but I'm thinking if the best way to do this is to have the main problem with that solution, you'll always have to use the subquery to get the latest version.

i.e.: 

  SELECT * foobar WHERE foobar_id = 2 and version = (select MAX (version) Foobar f2 WHERE f2 = 2)

This makes most of the questions more complicated and there are some performance deficiencies

So if you create your existing version of the experience and share the pro and opposition of each method, So it would be nice

Thank you

I like to get historical data in other tables. I can make foobar_history or something similar and make FK in foobar_id. This will prevent you from using a subcube together. This is an added advantage of not polluting your primary data table with many historical data which you probably do not want to see 99% of the time when you are accessing it.

Although this data is triggered to update, you will need to copy the current data to _history and then update.

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

By using Wordpress I have created a multiple selection box so that users can select categories to exclude. When the page is initially loaded, I see my predefined default option.
