Accessible Bristol meetup
I finally made it along to one of Accessible Bristol’s monthly meetups. Léonie Watson gave a talk on Custom Interfaces with ARIA, HTML5, & JavaScript. I’m a big fan. An amazing woman.
Take home points for me:
- It’s easier to make your dynamic websites more widely accessible than you’d think
- Look in this testing tool: http://www.powermapper.com/
- Don’t forget your accessibility tree – the DOM’s accessible cousin ;)
- Bootstrap and Ember are working hard to make their frameworks more accessible
- Look into ARIA support within SVGs
- Use aria-hidden class for non essential icons
- Web components and the benefits of extending HTML by extension
For more info check out Leonie’s website and the Coding like you give a damn presentation:

zgrep
Where have you been all my life? ;)
Grep within .gz file without uncompressing it first. One of life’s small pleasures.

strftime gotcha
It turns out in Python 2.7 datetime.strftime can’t handle dates before 1900. e.g.
ValueError: year=1066 is before 1900; the datetime strftime() methods require year >= 1900
