StackOverflow: Developer Survey Results 2019

This year’s results for StackOverflow Developer Survey are in. This is probably the largest survey of IT professionals, with nearly 90,000 participating this year.

As always, there are plenty of insightful findings and correlations in the results. But one that I was somewhat glad to see was the attitude towards Blockchain technology.

While the mainstream media continues to confuse Blockchain with cryptocurrencies, technical people do understand the difference. And the majority (29.2% + 26.2% = 55.4%) of the survey respondents think it is useful for a variety of things outside of the cryptocurrency.

And with all the hype around cryptocurrencies and Blockchain, the majority of the organizations are not working with the technology just yet. Furthermore, of those that do work with Blockchain, the majority is NOT using it for the cryptocurrency.

That is pretty close to my mental picture of what’s going on.

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!

Design for Blockchain


“Design for Blockchain” is a collection of articles about user interface and user experience design for blockchain and cryptocurrency projects and tools.  Blockchain, due to its nature, is quite a technical subject, so making it friendly for non-technical users is a challenge.  These articles are exploring the domain problem.




Get Started with Blockchain Using the new AWS Blockchain Templates


One of the greatest things about the Amazon AWS services is that they save a tonne of time on the reinventing the wheel.  There are numerous technologies out there and nobody has the time to dive deep, learn, and try all of them.  Amazon AWS often provides ready-made templates and configurations for people who just want to try a technology or a tool, without investing too much time (and money) into figuring out all the options and tweaks.

“Get Started with Blockchain Using the new AWS Blockchain Templates” is one example of such predefined and pre-configured setup, for those who want to play around with Blockchain.  Just think of how much time it would have taken somebody who just wants to spin up their own Etherium network with some basic tools and services just to check the technology out.  With the predefined templates you can be up and running in minutes, and, once you are comfortable, you can spend more time rebuilding the whole thing, configuring and tweaking everything.
