What are the correct pixel dimensions for an apple-touch-icon? |
|iphone|favicon|apple-touch-icon| |
I'm not sure what the correct size should be.
Many sites seem to repeat that the apple-touch-icon should be 57x57 pixels but site a broken link as their source.
[Hanselman][1]'s and [playgroundblues][2]'s comments suggest different sizes including 163x163 and 60x60.
Apple's own [apple.com icon][3] is 129x129!
... |
I don't think there is a "correct size". Since the iPhone really is running OSX, the icon rendering system is pretty robust. As long as you give it a high-quality image with the right aspect ratio and a resolution at least as high as the actual output will be, the OS will downscale very cleanly. My site uses a 158x158 ... |
Best way to copy a database in SQL Server 2005/8? |
|sql-server| |
I always create a new empty database and then do a backup and restore of the existing database into it, but is this really the best way? As it seems very error prone and over complicated to me. |
In all honesty, a combination of print and print_r() to print out the variables. I know that many prefer to use other more advanced methods but I find this the easiest to use.
I will say that I didn't fully appreciate this until I did some Microprocessor programming at Uni and was not able to use even this. |
The best way I can think of would be to use **Cygwin** over an **OpenSSH** connection.
Here's a document that explains how to do just that:
<http://www.ucl.ac.uk/cert/openssh_rdp_vnc.pdf> |
Depends on how much detail you want it to have, it needs to have the aspect ratio of 1:1 (basically - it needs to be square)
