Weekly Recap – August 10th, 2025

Spring Boot, Java, Go

This week on Substack focused on Go language internals and a practical Spring Boot feature. I covered how Go handles benchmarking in tests, what value ranges look like inside loops, and how slices connect to their backing arrays. For Spring Boot, I walked through adding captcha validation to login forms without making it overly complex.

On Medium, the week involved Java, Spring Boot, and Go topics. Java articles included projects like calculating totals with variables, merging arrays without duplicates, finding vowels, and handling division by zero without crashing. Spring Boot posts covered features such as link click tracking in email workflows, static hosting for frontend builds, file downloads with byte streams, and rate-based email notifications. Go articles focused on language mechanics from struct copying to channel behavior, type switches, and how make and new work with slices, maps, and channels.

This week will bring more Spring Boot, Java, and Go content. I’ve been getting great feedback on the Go articles, so those will be sticking around as a regular feature for a while. The plan is to keep building on what’s been covered so far, blending practical features with deeper looks at how things work behind the scenes.
