Simple math statements in bash in a for loop -

-

I am doing a lot to bash scripting and it is usually to avoid all costs, but I have to write a Bash script to execute a few simple things on a remote cluster. I have a problem for the following loop: {1..20} in <{p> 

  i {1..20} E for tax in {1..20} (i * i + j * j) ** 5. & Lt; --- Pseudo code! Done

Can you help me with this simple math? I have thrown $ everywhere and can not write it properly if you can help me understand how how to designate loops allocated in / bash and interpreted Bash math The limits (how do you square root?) I would be very grateful. Thanks!

Here's a decent solution: 

  for i in { 1..20} {1..20} Do the h for "scale = 3; sqrt ($ i * $ i + $ j * $ j)" | BC will output:  
  1.414 2.236 3.162 2.236 [... etc ...]

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. All st...

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...
