While running Lighthouse CI on GitLab CI, I came across a problem: Lighthouse CI wants information about the current git commit, but it couldn’t get all of that information. In that case, Lighthouse CI falls back to running the git command; however, in my docker images, I don’t have git installed nor did I want to do so. So, I set out to fix this shortcoming in both Lighthouse and GitLab by adding the necessary environment variable to GitLab CI and having Lighthouse use it. The result is that I submitted a PR to Lighthouse that was merged and included in Lighthouse CI 0.7.1 and an MR to GitLab that was merged and included in GitLab 13.11. Now users (including my future self) will have a smooth, Just Works™ experience with these two tools.
I discovered a bug in how Java handles file paths on Windows that has existed for 22 years. I reported the bug, JDK-8262277, then I submitted a pull request fixing the bug which got accepted. I also submitted pull requests to Spring (which were accepted for version 5.3.5) working around the bug so users of … Continue reading Fixing a Bug in Java
Organizations already automate running builds, executing tests, and performing deployments to free developers from tedium and improve reliability. The next step is to use automation to improve projects. Tools (bots) can submit pull requests that fix typos, optimize images, and more. I’ve had a great positive experience using a bot to perform the tedious task … Continue reading The How and Why Automating Dependency Updates
Java is supposed to be “write once, run anywhere” but in practice, there are always platform differences that can and do result in bugs. For that reason, and because in general it’s a good idea to test as much as possible, it’s nice to run tests (even for Java applications) on multiple platforms. As evidence … Continue reading Testing a Java application on Windows without Windows
java-httpclient-webclient-spring-boot-starter is a library that I created to provide a quick and easy way to use Java 11’s HttpClient as Spring’s WebClient’s client HTTP connector. If you’re using Spring Boot 2.3 or later, it’s worth checking out.
Reproducible builds are a set of software development practices that create an independently-verifiable path from source to binary code. https://reproducible-builds.org/ Reproducible builds are important and provide benefits in many areas, including: Security. Because the same input source code always provides the same output binary artifact, you know that no attacker modified the toolchain to inject vulnerabilities … Continue reading Reproducible Builds in Java
Version controlling database schemas facilitates repeatable deployments and consistent environments. The alternative is have a human manually perform database modifications; since humans are human, we tend to make mistakes especially when performing repetitive tasks, and our time is also very expensive compared to that of machines, so automating database schema changes is superior approach. More … Continue reading Version Controlling Database Schemas and Data with Liquibase
The Service Oriented Architecture (SOA) pattern is commonly found in the enterprise. SOA is an approach where components (services) communicate with each other over the network. Each service focuses on a specific goal. For example, an SOA ecommerce store may have a service for credit card processing, another inventory checking, another for user management, and … Continue reading Migrating Message Queue Based SOA Applications to the Cloud
In my role with Isobar, I’ve successfully migrated a number of enterprise applications to the Azure and AWS clouds. In the process, I’ve noticed a number of commonalities and taken some lessons learned. I keep these thoughts in mind at all times and have found they greatly contribute to success. Focus on “Why” It is … Continue reading Moving to the Cloud: Get Started With the Basics
