O’Reilly Technology Trends for 2022 @OReillyMedia

What does O’Reilly Learning Platform usage tell us about where the industry is headed?

We used data from the first nine months (January through September) of 2021. When doing year-over-year comparisons, we used the first nine months of 2020.

We looked at four specific kinds of data: search queries, questions asked to O’Reilly Answers (an AI engine that has indexed all of O’Reilly’s textual content; more recently, transcripts of video content and content from Pearson have been added to the index), resource usage by title, and resource usage by our topic taxonomy.

Security was frequently in the news in 2021, and for the worst possible reasons. A wave of ransomware attacks crippled important infrastructure, hospitals, and many other businesses, both large and small. Supply chain attacks, in which an attacker places a payload in software that’s delivered to its victim through normal distribution channels, occurred in both open source and commercial software.

Within software development, Everyone is talking about developer experience (DX): what can be done to make life better for software developers. How can their jobs be made more enjoyable, helping them to become more effective? That’s an issue that will become increasingly important as organizations try to keep programmers from jumping ship to another company.

Python, Java, and JavaScript are still the leaders, with Java up 4%, Python down 6%, and JavaScript down 3%. (“Python” and “Java” are both in the top five words used in O’Reilly Answers.) Although any change under 10% is small in the greater scheme of things, we’re surprised to see Python down. And, like last year, usage of Java content is only slightly behind that of Python if you add Spring usage to Java usage.

Our data is similar to TIOBE’s (in which the top languages are Python, C, and Java) and sharply different from RedMonk’s (in which JavaScript leads, followed by Python and Java).
