Of course, no 21st Century tour of sci-tech developments would be complete without a discussion of artificial intelligence, the white-hot area of research that’s expanding outward like a mini Big Bang. AI is everywhere these days, it seems, but a curious development over the summer suggests just how weird the future is likely to be.
In August, researchers published a remarkable study that suggests artificial intelligence can effectively identify people with clinical depression—just by looking at their Instagram photos. It … Read the rest

Although Google still sits well behind Amazon Web Services and Microsoft Azure in cloud revenue, with just 2.3 percent market share against AWS’s 44.1 percent and Azure’s 7.1 percent, according to Gartner data, 2018 could well prove Google’s breakout year.
That is, if it can just deliver on one, eensie weensie thing: helping enterprises operate more like Google.

Jenkins is one of the earliest and still one of the most-used continuous integration and continuous delivery (CICD) servers. It has lots of competition these days, but still has a robust community and a wide range of plugins (1,400 when I last checked). Even if you wind up using a different automation server, it is worth understanding how to use Jenkins: The underlying concepts of CICD don’t change much from one implementation to another, even though the vendors do tend … Read the rest
PostgreSQL (aka Postgres) is old as dirt, yet over the past five years it has panned out as pure gold. MongoDB got the billion-dollar IPO and AWS launched the mind-bendingly cool Aurora Serverless, but it’s PostgreSQL that keeps having its moment—again and again and again.
Now the world’s fourth most popular database, according to DB-Engines’ multicomponent ranking, PostgreSQL has a ways to go before it surpasses Oracle, MySQL, and Microsoft SQL Server. Yet at its current pace, … Read the rest
