Widgets is something that was never done well inside Page Builder. Still, a lot of third-parties provides useful widgets, so I made slightly better way to insert/update widgets. A component, that provides widget form in a single click:

Ok, I did some testing as I can tell GPT 5.1 loves REALLY LONG RESPONSES. So, made some tweaks, and really, really liking the feel of GPT 5.1 and gosh... is it fast! Very intelligent model. This one is good.

Actually had an error in the deployed code, so it actually fell back to Sonnet 4.5 😅 Really like Claude's responses here, hmmm. But have fixed and deployed GPT 5.1 as the new active model for now to see how that does.

Only the OG's still know what Magento U is these days. Rather than calling my offering the "Macademy University", literally everyone calls it the "Magento University". I can't use the "Magento" name in my branding (well, maybe I can now...), but I get that association for free,

From a branding standpoint, my main subscription should have been called the Academy. The "Macademy University" makes no sense. But, Magento U was a thing at the time -- and I liked the passive correlation. Now, Magento U is no more, so I "bought" their branding for free.

Anthropic's Bulk API processing is turning out to be super efficient in all ways. It cost me about $20 to send in about 8M tokens and get 1M tokens back. And it did all of this in about 3 minutes!

You can now find out what nearly 6,000 Magento classes actually do & when to use them! I've totally revamped the Magento Explorer beyond the initial 10 main modules, as it now covers all main classes within the 295 core modules. Access the full list of classes and functions at

VIBE CODERS DO NOT BUILD REAL APPS But then why do I get DMs like this literally every single day? How many videos do I need to create? How many stories do we need to tell? Why does Cursor make $1B ARR? How much more proof do we need? Using AI to build products is so much

Just updated Maggie Bolt to use GPT 5.1. I ran it through a few questions, and really like her responses when compared to 4.1. More personality and better formatting. dark mode = GPT 5.1 light mode = GPT 4.1 Let me know what you think:

It's a good design pattern to hoist rando string values into constants. Especially useful if you are managing multiple AI models and want better maintainability.

162 developers have taken my Adobe Commerce Cert-Prep Developer Pro course. Out of those... less than 10% have taken it 3 times or more! But stats show if you take the practice test 3 times or more, you'll get about an 80% -- very likely enough to pass the real exam which

You can just build stuff! Yesterday, I added some charts to my custom admin dashboard to track unique active users: - DAU: give you a quick pulse on daily activity - WAU: higher-level vantage point to smooth things out - MAU: direction trends over the longer term The charts
