Edit the connection, on the Connection tab, go to the ‘Advanced’ sub-tab, and in the ‘Others:’ box add the line ‘OPT_LOCAL_INFILE=1’. This should allow a client using the … Read more
Yup: if you create a <link> tag linking to a stylesheet and add it to the <head> tag, the browser will load that stylesheet. E.g. $(‘head’).append(‘<link rel=”stylesheet” type=”text/css” href=”https://stackoverflow.com/questions/2126238/lightbox_stylesheet.css”>’); However, as per @peteorpeter’s comments, this doesn’t work in IE 8 or under — there, you need to either: append the <link> before setting its href; … Read more

Caching just means keeping a copy of the data that you need so that you don’t have to load it from some slower source. For example, microprocessors often have cache memory where they keep copies of data so that they don’t have to access RAM, which is a lot slower. Hard disks often have memory … Read more

This works because you’re multiplying the time to wait by the index of … Read more
