Learning Log #3

List of interesting news, resources or issues and their solutions I have been lately dealing with.

Learning in public - is a quest to be as open as possible. But there’s also kind of a counterpart to such spreading movement, that has probably always been a part of the World Wide Web - dark web. Beware, not The Dark Web, but The Real Dark Web - rarely acknowledged majority of web developers.

From the talk New adventures in front-end by Vitaly Friedman.

How to make your application more accessible? What about to include No mouse day into your development process?

That’s enough for now, see you next time!
