Talking about technology (mostly)

Found out about this handy utility the other day: ScreenFly.

It allows you to test your website on various device form-factors. Handy!

Today I had to look up the CSS syntax for curved corners and I found this article which suggested:

#example1 {
-moz-border-radius: 15px;
border-radius: 15px;
}

Today I found this discussion which showed how to align a table in the center of the page in HTML:

table {
    width: 50%;
    margin-left: auto;
    margin-right: auto;
}

or:

table {
    width: 200px;
    margin-left: auto;
    margin-right: auto;
}

Found myself reading about values, variables, and literals in JavaScript.

Found myself looking up the syntax of the Array splice method.

Found a handy web-based utility for encoding/escaping text in JavaScript: Text Escaping and Unescaping in JavaScript.

To trim new lines in bash:

tr -d '\r\n'

To download a file from the web and send its contents to standard out, try this:

wget -O - -o /dev/null https://www.unconfusable.com

Here’s an interesting article from way back in 2004: XML on the Web Has Failed.
