I have /tmp and /home on different partitions. When trying to move a file from /tmp to /home using File.renameTo() — it fails. Turns out one has to copy and delete the file himself, renameTo works only inside single partition.

Notka dla siebie - czy takie zmiany w /etc/sysctl.conf faktycznie przyspieszą działanie Ubuntu na komputerze z mnóstwem ramu?

It turns out that Internet Explorer caches AJAX requests (how clever). If you’re using $.ajax(), you can pass cache: false option to it, but if - like me - you’re using $.get() and $.post(), just use

$.ajaxSetup({cache: false});

somewhere at the start of your script.
