I manage several information flows based on my interests.
This is actually my main source of information. I'm subscribed to over 20 weekly and daily newsletters with topics ranging from Front-End Development to Web Architecture (Frontend BUZZ, JSK Daily, Front End Newsletter, Sitepoint Versioning, The Changelog to name a few). I'm scheduling them at a precise time of the day, so I'm able to easily process everything.
The best way to learn a new technology or language is to build something with it. So, if I find something intriguing during the work week I start playing with it in the weekend. It can be a toy project, it can be a fully-featured project or just a couple of small code samples. For me, writing code is the way to memorise anything new.
This is pretty straightforward - try to share what you have learned and found. Take Hashnode for example - you can easily share various kinds of resourses you think can help the community, you can write articles, where you share your personal knowledge and experience, you can share your opinion about topics and see how they do or do not differ from the others and most importantly , you can help other developers. You will not only rise as a developer, but as a person too.
