Using the NetworkManager’s DNSMasq plugin

Fedora Magazine runs a handy article for anyone using work/corporate VPNs from a home computer – “Using the NetworkManager’s DNSMasq plugin“. This is also not the only use for the DNSMasq plugin. It comes in useful when you work local cluster setups for development or testing. Furthermore, pretty much any setup where you need to route DNS queries to different servers, this can either be used out of the box, or provide good ideas as to how to solve the problem.

Dgraph – fast, transactional, distributed graph database

Dgraph is a fast, transactional distributed graph database, written in Go. It’s Open Source too.

If you need a quick introduction to graph databases or if you are wondering whether you need to use one, here’s a good video to get you started.

For even more insight, read “Why Google Needed a Graph Serving System“. There are some interesting examples of problems, solutions, and data discovery. For example:

Cerebro would often reveal very interesting facts that one didn’t originally search for. When you’d run a query like [us presidents], Cerebro would understand that presidents are humans, and humans have height. Therefore, it would allow you to sort presidents by height and show that Abraham Lincoln is the tallest US president. It would also let people be filtered by nationality. In this case, it showed America and Britain in the list, because US had one British president, namely George Washington. (Disclaimer: Results based on the state of KG at the time; can’t vouch for the correctness of these results.)

Learn Enough Docker to be Useful

“Learn Enough Docker to be Useful” is a series of articles (so far 6) that explains different parts of Docker in a very simple and straightforward way. Here are the parts so far:

Blockchain : The Freeland Passport

Blockchain technology has been in the news a lot lately. Most of the attention however was on the cryptocurrencies and ICOs. But that’s a very tiny part of what the blockchain is all about.

There are many different applications of the blockchain technology – some we already know and some are yet to be discovered. But there’s this one particular milestone, which I consider of ultimate importance.

Freeland, which is a set of social, technological, and business experiments has recently announced the Freeland passport. Watch the above YouTube video (in English, or this one in Russian), which showcases the passport.

Now, with the quick “yes” answer to your question of “Is this real?”, let me ask you a question in return: is your mind blown yet? Mine is.

I think this is a very important milestone in major social, cultural, legal, technological, and financial transformations that are already changing the world. This passport is a beautiful bridge between the two very complex, yet very different worlds we now live in – the physical and the digital.

This is not the beginning, and this is not the end. But this is one of those moments in history, which a lot of people today won’t recognize as such, yet the generations to come will definitely point out and understand.

Ladies and gentlemen, we are living in the very exciting times!
