Web Excursions for June 13, 2015

[Tweet : nvALT]

Web excursions brought to you in partnership with Udemy. Learn Anything.

This is a developer-centric pack of links. It’s been one of those weeks.

kcrawford/dockutil
I have a lot of defaults write notes, but this little Python script turns OS X Dock modifications into intuitive command arguments. Now I can stop having to look up defaults write com.apple.dock persistent-others -array-add url-tile.
benjamine/jsondiffpatch
I know there are probably very few people who are looking for this, but I had an itch to scratch and was ecstatic to find that Google’s diff-match-patch had been ported to JavaScript.
karan/slack-overflow
Add a StackOverflow search to your Slack channel so you can answer programming questions without all the hassle of opening a web browser.
Sassline
If you design for the web, you’ve been inundated with typography talk for the last few years. Decade, really. There have been a few great tools to simplify vertical rythm, and more that have adapted for responsive design. Here’s a collection of base typography styles and Sass mixins that make it simple.
postcss/postcss
I’ve gotten good with Sass, but I make a strong effort not to get overly comfortable with any technology. Sticking with any library for more than 6 months is how I’ll know it’s time to quit tech and work on my carpentry skills. 



PostCSS is a tool for transforming CSS with JS plugins. These plugins can support variables and mixins, transpile future CSS syntax, inline images, and more. 


[…] PostCSS can do the same work as preprocessors like Sass, Less, and Stylus. But PostCSS is modular, 3-30 times faster, and much more powerful.
