Shared memory is the most basic, primitive way to communicate between processes or threads if I understand correctly. Most of IPCs should be built on top of it (probably in kernel level). ... yes, using shared memory to communicate often means a need of proper locking/synchronization which slows down the communication, but don't other IPCs use locking/synchronization internally to coordinate stuff between processes/threads? Thus in my opinion, theoretically there should be no other IPCs (including Unix domain socket) could beat shared memory. Is it true? -- Justin545 ( talk) 02:45, 9 October 2013 (UTC)
I wouldn't know if this would be the correct place to these types of questions but.. how Imgur redirects to some image after you upload it? in the network viewer when you POST an image you can't see the url where your image is being uploaded so how imgur redirects me there? 190.156.129.50 ( talk) 04:37, 9 October 2013 (UTC)
It's javascript. You only need a single line of code.
function getImageUrl() { return "8eBynOh" }
window.location.href = "http://imgur.com/" + getImageUrl();

I am going to ask a hipothetical question here. If someone has downloaded a component of Mozilla Firefox that change the banner of the browser in Linux. How can I add it to a PC that runs Windows 7 wothout being connected to the internet. Which are the folders in Linux that I have to copy and paste to Windows?

Without examining IE's source code it's anyone's guess. Anyway, seems to have been fixed in IE10. Sebastian Garth ( talk) 13:50, 9 October 2013 (UTC)
The trigger seems to be that there is no closing form tag, as mentioned in the discussion linked from that page. The CSS seems to be essential as well. Anything more we could do to explain what specifically leads to that causing a crash in IE would be speculation. Katie R ( talk) 17:26, 9 October 2013 (UTC)
Are my eyes deceiving me or isn't there a closing form tag at the start of the second line after the opening form tag? Looks like moderately well formed HTML to me though I would be inclined to put the table inside the form rather than vice versa. 86.147.202.194 ( talk) 21:13, 9 October 2013 (UTC)
Over the years and using several different computers and external hard drives, I now have acquired a vast collection of mainly digital pics, many of which have been copied from C to D to external drives and back again, thus also creating many duplicates. I am now spending my retirement tidying my files and want to have a sanitised master external hard drive to store all my pics, but only one copy of each. Is there a way I can instruct my laptop to search for and delete all these duplicated files. Many thanks in anticipation. 80.6.13.178 ( talk) 16:19, 9 October 2013 (UTC)
