A CSS pseudo-element is used to style specified parts of an element. In some cases you can style native HTML controls with vendor specific pseudo-elements. Here you will find an list of cross browser specific pseudo-element selectors.

Styling native elements

Native HTML controls are a challenge to style. You can style any element in the web platform that uses Shadow DOM with a pseudo element ::pseudo-element or the /deep/ path selector.

video::webkit-media-controls-timeline {
  background-color: lime;
}

video /deep/ input[type=range] {

Rename field using migrations in django 1.7
To change a field name in django 1.7+
1. Edit the field name in the model (but remember the old field name: you need it for step 3!)
2. Create an empty migration
$ python manage.py makemigrations --empty myApp
3. Edit the empty migration (it's in the migrations folder in your app folder, and will be the most recent migration) by adding
migrations.RenameField('MyModel', 'old_field_name', 'new_field_name'),
to the operations list.

Comparing two ways to load non-critical CSS

I wanted to figure out the fastest way to load non-critical CSS so that the impact on initial page drawing is minimal.

TL;DR: Here's the solution I ended up with: https://github.com/filamentgroup/loadCSS/

For async JavaScript file requests, we have the async attribute to make this easy, but CSS file requests have no similar standard mechanism (at least, none that will still apply the CSS after loading - here are some async CSS loading conditions that do apply when CSS is inapplicable to media: https://gist.github.com/igrigorik/2935269#file-notes-md ).

Seems there are a couple ways to load and apply a CSS file in a non-blocking manner:

Show a progress bar when a form is submitted (and prevent more than one submission per document).
/*
Show a progress element for any form submission via POST.
Prevent the form element from being submitted twice.
*/
(function (win, doc) {
'use strict';
if (!doc.querySelectorAll || !win.addEventListener) {
// doesn't cut the mustard.
return;

Earlier, amidst many other tweets about a new css preprocessor, Myth, I tweeted "Avoid snake oil, people. It takes more than a pretty website and a good marketing message. You have to actually deliver code that works." to which @necolas replied "assume your peers have good intentions".

Absolutely. This is sound life advice. I endeavor to do this and the message I wanted to convey to everyone today could have been conveyed without resorting to using such negative phrases as "snake oil". So to the guys at Segment.io and especially to Ian Storm Taylor, I'd like to say I'm sorry. I was frustrated, but that doesn't excuse that tweet.

I'd like to talk briefly about why I was so frustrated.

Even people with great intentions can still do harm. Recently a nice guy decided he would give away a thousand dollars by ["making it rain" dollars at a mall](http://abclocal.go.com/kabc/sto

git hook to run a command after `git pull` if a specified file was changed.In this example it's used to run `npm install` if package.json changed and `bower install` if `bower.json` changed.Run `chmod +x post-merge` to make it executable then put it into `.git/hooks/`.

kanmeiban / Why Recruiters Are Universally Hated
Created November 22, 2013 20:22
Dealing with recruiters is as nice as dealing with faecal matter. You'd better flush as soon as possible.
Why Recruiters Are Universally Hated
On 14. January 2013 I was invited for a job interview in London by Mr Ethan James of recruiting company
TestDriven IT Group on behalf of his client, a start-up looking for Ruby on Rails developer. Mr Ethan
James proposed I should fly with a low cost jet to get full reimbursement on my tickets. Hower I prefer
rail and sea transport to air travel beacause of their smaller environmental footprint so we agreed that
TestDriven IT Group will cover only half of my travel costs. The interview went well, I wasn’t hired so
I traveled back to my home country through the snow covered Europe, sent a scan of the tickets to the
recruiters upon my arrival and waited for the reimbursement to come.
