Change your default SSH username
If you’ve not had your own choice of username on your machine (for example, if your company imposes a username policy), you can set up a different default username for SSH in ~/.ssh/config:
Host *
User chris

Chrome 4 currently appears to be the only browser to implement the W3C’s border-radius property: http://www.w3.org/TR/2002/WD-css3-border-20021107/#the-border-radius
border-top-left-radius: 1em;
border-top-right-radius: 1em;
You can produce the same result using proprietary attributes in Firefox 3.5 and Safari 4:
/* Firefox */
-moz-border-radius-topleft: 1em;
-moz-border-radius-topright: 1em;
/* Safari */
-webkit-border-top-left-radius: 1em;
-webkit-border-top-right-radius: 1em;

To copy files from one directory, you might usually do:
cp dir/* anotherdir/
If you try to do this with a particular large number of files, you may encounter the ‘argument list too long’ error. In this case you can use:
find . -exec cp {} /path/to/anotherdir/ \;

By default, Mobile Safari assumes that the page is 980px wide and sizes the viewport accordingly. If your page is significantly smaller, you can use the viewport meta tag to configure the viewport dimensions. For example:
Detailed documentation is available at developer.apple.com. In portrait mode, the viewport is 320px wide; in landscape mode, it’s 480px wide.
