CD at scale: the success story of a big rewrite

Back in March, I gave a presentation at the Continuous Delivery Amsterdam meetup. You can watch the video here. The title is “CD at scale: the success story of a big rewrite”. It’s about how we applied CD in a big project that involved complete rewrite of our storefronts at work.

Keeping it simple with microservices communication

The term microservice has been getting a lot of hype and attention. I have to admit that I fail to understand what’s the big deal about it. The best practices about microservices are similar to the ones we should apply to everyday software design. Avoid tight coupling. Single responsibility principle. Keeping things simple. Even those principles go back to the old Unix mantra of doing one job and doing it well (and that’s from 1978). And even that could in turn be labelled just “common sense”.

On Code Comments

I recently joined a different team at work, working on a whole different project. For the past one to one and a half year, I did my bit in building up a culture in my old teams regarding code quality and the moral responsibility of a developer towards the codebase (also known as boy scout principle). Now, we have to start all over from scratch with the new team.

Worked fine in DEV, OPS problem now

During the past year at work, we did a complete rewrite of our websites from scratch. Not only did we aim to build a mobile-first responsive website with high performance, we also tried to do it with continuous integration and continuous delivery in mind. All that on a proprietary platform not built with CI in mind. This was a very big challenge, which involved a culture change in a lot of people. Unfortunately, the project had a hard deadline. Things were left out. Corners were cut.

Backup Strategy

Taking a backup was arguably easier back in the days. You had only one computer, your data could fit inside a few floppy disks and the only cloud in your life was the one that would indicate chances of rain later in the afternoon. Things are a bit different today. Nevertheless, the need to preserve your files, your work, and your digital memories, remains the same.

20th Century Code

I spent the previous week migrating some old code I had laying around into GitHub. More specifically, I had a single git repository named “Legacy” that contained all sorts of projects and demos I had created over the years. It’s difficult to find exact dates but I found a few that go as back as 1998, so I can justify the title of this blog post.

On the left-pad drama

This week the internet exploded in drama after 11 lines of code got unpublished from npm. If you didn’t read about it, the summary is that the developer of left-pad removed his package from npm, after npm renamed another package of his because of some name conflict with some other company’s trademark or so. Lots of other packages broke because of this due to the missing dependency. What is interesting here, is that this removed left-pad package consists of a single function (only 11 lines of code). How can that tiny package break the internet? Continue reading “On the left-pad drama”
