The Zing Virtual Machine (ZVM) has been developed to address the performance-related issues that result from a managed runtime environment that is provided by the JVM. These fall into two specific areas: Application response latency caused by the garbage collector (GC) pausing application threads to perform its work. Reduced initial throughput when an application is…
Keeping Java production systems secure and up-to-date can be an operational challenge. There’s always a balance between disrupting operations and reducing the risk of vulnerabilities. No time is that trade-off more apparent than the third Tuesday of January, April, July and October when the steward of Java releases new updates. Java has been updated on…
For those of you old enough to remember the film, Marathon Man, there’s a famous scene with the quote, “Is it safe?” Azul has just ensured that the answer to that question is yes when posed about running an application on Java SE 8 that transfers data across a network. In a networked environment, it…
Although Java started life targeted at desktops, its popularity has really grown to dominate the server and subsequently cloud spaces. Many people would dismiss Java on the desktop, but you would be surprised at the number of people and organisations still using it. The reality of “Write once, run anywhere” dramatically simplifies the deployment of…
TechRepublic recently published an article about languages that developers love and those that they hate. This produced an interesting set of results since Java was the third most loved language as well as the second most hated. Clearly, Java, as a language, polarises opinion. When I tweeted about this, I got one reply which quoted…
There was an interesting discussion on the Java Champions alias recently under the title, “Fear of Java”. The initial post was related to a University faculty that was evaluating which version of Java to use. Given the issue that it brought up, I thought it was worth discussing in a blog post. I’ll quote…
It occurred to me recently that I had just passed a substantial milestone in my career. I started working for Sun Microsystems in February 1996 but, at that time, with Java being so new my role was to help drive adoption of Solaris on Intel with major ISVs like Oracle, Informix and Lotus Notes (hands…
Four big things are happening in April 2019 that I can think of right now: On the 25th we have the release of Avengers: Endgame. For anyone who’s a Marvel fan, this is big news, especially the way that Avengers: Infinity War ended. I think it’s going to take some pretty creative writing to get…
I’ve written several blog posts that list out all the changes for each of the most recent releases of Java (JDK 10, JDK 11). With JDK 12 just having been released, it seemed the obvious thing to produce another blog in this series. I’ll be doing the flip side of this later, which is the…
Around the middle of the 15th century, Johannes Gutenberg introduced the metal movable-type printing press. I think it would be easy to argue that this was one of the most significant inventions in history for enabling widespread access to information; something today we take very much for granted. The metal type pieces of Gutenberg’s press…
Last month was of particular significance to both Java developers and users. The reason was the release of update 202 of Oracle JDK 8, which was the final public update (for commercial users) of JDK 8 from Oracle. Users now need to think carefully about their strategy for updating the Java runtime in the future….
Last week was the annual Jfokus conference held, as usual, at the Waterfront Conference Centre in Stockholm. Looking at the Jfokus archives, the conference started back in 2007 and attracted about 450 people (an impressive achievement for a new conference). This year was the thirteenth edition, and there were over 2,000 people in attendance. When…
