RSS is not dead. At least not for me :) I use NewsBlur to track and read 50+ various feeds - tech, travel, personal blogs. Today I want to share a list of software engineering blogs that I find very helpful and keep in my list for a long time.
http://techblog.netflix.com - Netflix has one of the best blogs. They always post very interesting articles explaining their architectural decisions in depth.
http://martinfowler.com - another must read, Martin Fowler. I don’t think he needs introduction :)
https://aphyr.com/posts - distributed systems explained (and ruined). His Jepsen series is a great practical introduction to distributed computing and related problems. He proves that everything can be broken (well, except Zookeeper).
http://highscalability.com - lots of “real life architectures” - reviews that explain modern scalable architectures from different companies, from startups to enterprises.
https://github.com/blog/ - less actual engineering, but it’s important to be informed about new GitHub features, right?
http://nerds.airbnb.com - AirBnB shares interesting details about problems they solve.
https://codeascraft.com - the same from Etsy, their Performance Reports series is pretty unique.
https://eng.uber.com - insights from Uber, always in detail.
https://www.paypal-engineering.com - diverse topics from PayPal.
http://code.hootsuite.com - another really diverse blog from HootSuite: JVM, DevOps, front-end, etc.
http://engineering.khanacademy.org - really great content, sometimes not about engineering at all, but take a look!
https://aws.amazon.com/new/ - must have stream of updates if you use Amazon Web Services.
http://www.cakesolutions.net/teamblogs - good DevOps and Scala content, weekly digests!
http://blog.akka.io - obviously useful only if you use Akka ;-) or planning to.
As a bonus a few great personal blogs:
