The largest Magento 2 class reference in the world
Hey Reader, I just shipped something I've been wanting to build for a long time: the largest Magento 2 class reference in the world. Nearly 6,000 classes across 295 modules, every single one analyzed and enriched with plain-English explanations, code examples, constructor dependencies, events dispatched, database tables, and customization guides. If you've ever needed to understand what a specific class actually does, how it's injected, what events it fires, what tables it touches, ...this is...
🟧🟦🟪🟨 M Bytes #25: Become an AI-assisted developer with Claude Code
🟧🟦🟪🟨 by M.academy Hey Reader, Do you know anything about AI-assisted agentic coding? It's where you create or define some requirements for a feature, feed it to the AI, and work with it to build something awesome. Believe it or not, I used this exact approach to build 99% of my new custom course platform with AI (video walkthrough ↗). The tool I used for everything: Claude Code. To me, it's like the Magento of agentic tooling. It's the only generative coding tool out there that gives the...
🟧🟦🟪🟨 M Bytes #24: AI wrote 99% of my production course platform
🟧🟦🟪🟨 by M.academy Hey Reader, I've been continuing my work with Claude Code, and the rabbit hole goes deep 😅. But rather than just tinkering with it on the side, I'm building real, actual stuff with it. The Magento 2 Coding Jumpstart course was recently migrated to the new course platform (which I call Codex) and it was built with CC. You can watch some lessons on the new interface. I still need to integrate Maggie Bolt (the AI tutor) as well as comment functionality, but the build has gone...
🟧🟦🟪🟨 M Bytes #23: Using just a Docker tag does not ensure predictability
🟧🟦🟪🟨 by M.academy Hey Reader, So you may notice that things look and feel a bit different here... and that's because they are! The new M bytes logo signifies that we are covering all of the different edges of the Magento ecosystem -- and this includes everything from PHP, Docker, AI , MySQL... and much more. I'll also be covering only one single topic with every issue. My goal is to upgrade your skills around the entire stack, so you can extend your current working knowledge about topics you...
🟧 M Bytes #22: A few lessons about Docker -- want more?
by M.academy Hey Reader, I'm finding Docker to be increasingly relevant in the dawn of AI coding. You'll typically want to test out new code in a containerized environment before deploying it (eliminates the "it works on my machine!" madness), or provide the AI with a way to run rogue without your oversight (such as running Claude Code within a container using the `--dangerously-skip-permissions` flag). I've been using Docker for well over a decade and was an early adopter, using it in my...
🟧 M Bytes #21: The Magento cache command that could break prod
by M.academy Hey Reader, Last week, a dev messaged me: "I ran cache:flush instead of cache:clean on prod, and now our site's throwing errors. Why?" This is exactly why Adobe puts this type of question on the certification exam. On the surface, cache:clean and cache:flush seem identical. Both clear the cache and make changes visible. But one deletes from matching tags, and the other nukes the entire cache storage (including external services!). When you flush, you are also wiping caches from...
🟧 M Bytes #20: Never gonna make you cry (over Adobe Commerce certifications)
by M.academy Hey Reader, After a couple years in the making, we are celebrating this week's M Bytes with the release of M.academy's newest course: Adobe Commerce Developer Professional Certification Prep This is the only cert-prep course created (by anyone) within the last few years, and the only one based on the newest version of the exam, AD0-E724. I just opened up a few more lessons from the course so you can get a feel for the lessons. They are quick, short, and easy to digest. Rick...
🟧 M Bytes #19: Can you "vibe code" a production-ready app?
by M.academy Hey Reader, M.academy's upcoming Adobe Commerce Developer Professional Cert-Prep course is almost complete! We're in the final stretch, and have made a ton of updates to the course platform as well. This includes making upcoming lesson percentage visible in the progress bar, and better highlighting the current lesson you are on (so you don't get lost): This app is already in production. We haven't really officially announced it yet (and are still working on completing it), but...
🟧 M Bytes #18: Creating a generation of incompetent programmers
by M.academy Hey Reader, I had post go semi-viral on LinkedIn yesterday, and it was all about how we are creating an entire generation of incompetent programmers. As a teacher, I can't help but think all of the ways newb developers are just not gonna make it. And how others — smart enough to get by without the help of AI — are letting their brain atrophy. We need to take back some agency. Own the process. Push back on the AI/LLM and guide it, rather than have it guide us. This goes into a...
🟧 M Bytes #17: The GitHub-to-Magento trick every dev should know
by M.academy Hey Reader, June already. Where the heck did the first half of 2025 go? 🙃 Ever feel like you're running a marathon without shoes? That's been my 2025 so far. I hit 40 ready to conquer the world. Instead, I spent most mornings wondering if I could even get out of bed. Major sciatica, back pain, massive fatigue... it all took over. I was almost ready to lay down and just tap out. But I pushed through: I trained and worked with my AI coach to help me through rough times and refined...
