Funky css selector

The following code targets any div with the word “section” in the title. It can be “section3″ or “section-Four”, it doesn’t matter, as long as it contains the indicated string, the subsequent styles apply.

div[id*='section'] { color: red; }

Changing the styles of a Kickstarter widget for your website using php. I've been doing this since a while to make various widgets fit into places.

This file will work as a proxy, all you need to do then is to src="" this ( above ) file instead of the kickstarter / indigogo ... src

cool code in ui.draggable.js

That's a pretty amazing if statement from the jquery ui package!

// Yes, I know, this is insane ;) if(!((l-d < x1 && x1 < r+d && t-d < y1 && y1 < b+d) || (l-d < x1 && x1 < r+d && t-d < y2 && y2 < b+d) || (l-d < x2 && x2 < r+d && t-d < y1 && y1 < b+d) || (l-d < x2 && x2 < r+d && t-d < y2 && y2 < b+d))) {….}

Ya know what they do?

If you've been using css you probably know this one and were told not to use it because if iE. .class > .class { }

Any idea about those two?

.class + .class { } .class ~ .class { }

Or this one?

input[type="radio"]:checked + .item ~ .item { }

Ok I don't have much time but here goes.

+ selects the next following node ~ selects all following nodes Imagine you have a list of p tags in your html document. <p>1</p> <p>2</p> <p>3</p> <p id="x">4</p> <p>5</p> <p>6</p> <p>7</p>

p { background: red; } - will select all p tags in the page #x + p { background: red; } - will select the 5th #x ~ p { background: red; } - will select the 5th / 6th & 7th

I think only supported by Chome and I reckon webkit browsers, haven't checked but chrome works alright. So if you're doing ipad dev i think you'll be fine

Periodically clear all logs

People are against it and the internet tells me I should use logrotate ~~~~ But I'm not too keen on digging into log archives so I decided i'm going to use this crontab script to clear the logs on my server on the first day of every month at midnight.

00 00 1 * * for logs in `find . -type f -name "access.log"`; do > $logs; done 00 00 1 * * for logs in `find ./srv -type f -name "error.log"`; do > $logs; done

Sorted

Sorting out MySql

I've never stopped using the root user for mysql on my server, so i felt it was time to create a new user and start using this one instead of root. Also i wanted to update the mysql root password with a better password.

# Log into the server then # Log into mysql

mysql -u root -p

## Create a new user

mysql> CREATE USER 'newuser'@'%' IDENTIFIED BY 'password';

## Grant everything to the new guy

mysql> GRANT ALL PRIVILEGES ON *.* TO 'newuser'@'%' WITH GRANT OPTION;

## Check if the user was created via

mysql> select User from mysql.user;

## Exit out of mysql and if you want to change the root password you can do so using this command

mysqladmin -u root -p'oldpassword' password newpass

These new css3 selectors are as follows: [att^=val] – the “begins with” selector [att$=val] – the “ends with” selector [att*=val] – the “contains” selector

_gaq"==a.i?Z:M.u(a.i)

Been digging in Google codes, not sure why, suppose it's a little cloudy in here ~~~ Was trying to look for the first instance of _gaq array, well that's it.

Not sure if their code is either only readable only in the language of cat, purposely obfuscated using a=b;b=a[c];] thus causing severe brain exhaustion, or just simply miles ahead of my pea brain's main core accelerator.

My guess is the latter.
