jquery - How well does JavaScript scale? -

-

I was working on this carousel thing, using it. It works very well with some images, using Mootools. However when I added 70 photos (around 30k each) then it stopped working well. Spending some time poking around in the code of iCarousel it looked very nice and stable. So it started thinking to me: Does the script (which is overflow: hidden div), animates the devices in Moto, Firefox on Ubuntu, or can not handle javascript too much? If so, how much is it?

I think it's hard to say, but it would be really good to know that Javascript will be sluggish and useless, before it's preferably developed.

In addition to other answers, I will tell you with a hard experience which combines DOM elements in the browser like the canvas tag Direct drawings are actually really slow compared to APIs. In the bridge between JavaScript and DOM, there is not only too much overhead, but also every feature changes in the browser.

There are ways around something like this, such as ensuring that your animated extents are performing: complete set in their CSS (thus eliminating the need to take them out of the document flow, reffling ) And in your code to make sure when you really need to change, you will only touch the Dome.

A DOM document segment can be tampered with, and then inserted into the dom, and it is much faster than manipulating a portion of the dom displayed on the screen.

And also mention event handling stuff other people.

Javascript scaling? Yes, yes, can it scaling browser dome? Not likely that future browsers will be better at this.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

I am trying to create a back-end for my mobile application. I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image.

Another option is to use and load the image.

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
