[Packt]( Are you ready for 2019? [$5 Sale]( Hey {NAME}, Are you ready for 2019? New tech and new trends emerge every day, and your learning time is precious. Avoid going in the wrong direction with Packt’s take on what not to learn in 2019. Cryptocurrency might falter in 2019 2018 saw Blockchain rise. 2019 might see it fall. Hyped as one of the most exciting frontiers of tech, cryptocurrency has struggled with a number of high-profile crashes and coin-offerings looking like pyramid schemes. What should I learn instead? What Blockchain offers is the ability to decentralize databases. The reason it’s so popular is precisely because there is a demand for a database that is both scalable and available to a variety of parties. If you want to engage with Blockchain in 2019, this is the edge you should be looking for.

We’ve seen a change of emphasis in data towards AI and cloud computing, and with it the slow decline of Hadoop. In a world that increasingly cloud native, it simply doesn’t make sense to run data on a cluster of computers - instead, leveraging public cloud makes much more sense. What should I learn instead? As big data evolves, the focus will on broader architectural questions about what data you have, where it needs to be stored and how it should be used. The future of big data largely rests in tools like Spark, Flink and Kafka.

In 2019, that debate has all but disappeared with Python emerging as the go-to for working with data. What should I learn instead? This is obvious - if you’re worried about R’s flexibility and adaptability for the future, you need to learn Python. But it’s certainly not the only option when it comes to machine learning - the likes of Scala and Go could prove useful assets on your resume, for machine learning and beyond.
