Day 1 of JavaOne 2016 topics: learning about Java 8&9 features, Docker for Java developers, and development tools for Java EE 8. InfoQ highlights a few of the day's interesting sessions.
Continuous deployment results in a higher sense of responsibility and better quality of deployments, argues Paul de Raaij, technical pathfinder at Coolblue. Coding standards prevent your code base from becoming a mess, automated inspections are great for tedious and boring checks, and manual checks are great for checking if the logic or use of code actually makes sense.
At QCon New York 2016, Etsy software engineer Stefanie Schirmer told how her company successfully transitioned to an API-first architecture that supports multiple devices, addresses server-side performance problems, and was quickly adopted by development teams.
Stefan Thies, DevOps Evangelist at Sematext, in a recent post discusses ten important container monitoring metrics and their implications on operating Docker containers, specifically when running many containers per host. Combined in a single correlated view these metrics provide a starting point for monitoring Docker-based environments.
Windows Management Instrumentation (WMI) is a primary source of data when monitoring Windows systems. Given that the performance counters available vary from machine to machine, a tool is needed to list all counters available. The WMI type provider is one possible option to explore WMI performance counters.
Android N introduces a hybrid runtime using compilation + interpretation + JIT to obtain the best compromise between installation time, memory footprint, battery consumption and performance.
This post describes the applications of the shooting target in kanban board introduced by Tomas Rybing.
Censum, the Java garbage collection analysis tool by jClarity, has reached version 3.0. The main new features of the new version include the ability to analyse Safepoint logs, new graphs showcasing the behaviour of the G1 garbage collector, and a set of analytics to highlight whenever applications force to much OS activity.
At the microXchg conference, held in Berlin, Adrian Cockcroft presented “Analyzing Response Time Distributions for Microservices”. Cockcroft demonstrated how the combination of his Spigo microservice architecture simulation tool and the online Guesstimate Monte Carlo method tool can be used to visualise and experimentally simulate request response times within a complicated microservice system.
For a long time now developers have been asking why Visual Studio hasn’t made to switch to 64-bit. Rather than effort or opportunity cost, the primary reason is performance. Rico Mariani of Microsoft explains.
Klaus Leopold gave a talk at the GOTO Berlin 2015 conference in which he elaborated why focusing on team-level performance often leads to local suboptimalization and doesn't increase agility across the team. InfoQ interviewed him about why installing agile frameworks does not help to increase agility, how kanban can be used to increase collaboration, and benefits that teams can get from kanban.
Kevin Goldsmith talked about how Spotify uses microservices to break down architectures and be innovative at the GOTO Berlin 2015 conference. He argues that Microservices are easier to test, deploy and monitor than monolithic applications. Spotify also aims to have as few as possible dependencies in their product, and microservices are very helpful for that.
People can tell stories and express themselves when trying to solve complex problems using Lego. Jens Hoffmann facilitated the session "Prototyping an Agile Culture with LEGO® SERIOUS PLAY®" at the GOTO Berlin 2015 conference.
At DockerCon EU 2015 Brian Christner presented an overview of ‘Docker Monitoring’ and shared best practices, a guide to the Docker stats API, and a comparison between three popular monitoring options: cAdvisor, ‘cAdvisor + InfluxDB + Grafana’, and Prometheus.
James Lyndsay did a workshop titled "a nest of tests" at the Agile Testing Days 2015. In this workshop he explored how you can design large collections of tiny tests and visualize their output to test systems, and showed how tools can help you to do it. InfoQ interviewed him about this testing approach.
