Back in they day, I ran a Tumblr blog named Magento Quickies where I’d post shorter, less in-depth posts about my travels through Magento’s source code. This Programming Quickies categories is the successor to that Tumblr blog. You’ll find all the old Magento Quickies content here, as well as new short posts about programming in general.
This section has its own RSS feed, the old Magento Quickies feed should should be redirecting, and we’re cross posting notifications for new posts over to magento-quickies.tumblr.com. In other words, you shouldn’t need to know any of this, but the duct tape that keeps the internet held together isn’t aging well, so your mileage may vary.
Below you'll find all the Programming Quickies articles on the site, followed by a chronological listing of the same. You may also browse the 7 series directly via the following links. Pestle, Four Steps to Async Iterators, Checking in on OpenMage and Magento in 2020, Text Encoding and Unicode, Shopware's Development Environment, A Sentimental Gen-X Programmer Culls his Tech Books, and, Containers, Containers, Containers.
Magento 2, even community edition, comes with a “full page cache” out of the box. This caching system lives near the top of Magento’s application dispatch. The frontcontroller will skip action controller dispatch if it can find a cached version of the page. You can turn this feature off in the backend at System -> [...]

astormMagento 2: Sending a Custom Header/Response from a Controller This one’s an interesting example of the challenges faced when refactoring legacy code, as well as the limitations of what a “classical OOP” approach can do for you in a PHP enviornment. First, this answer, while correct in the fact that it works, is not [...]
astormThis is quick, high level, possibly incorrect, overview of how Magento 2 runs applications, and what the kernel of its system architecture looks like. This is the level above MVC/MVVM, and will only be of interest to folks (like me) who need to know how everything works. From a high level point of view, Magento 2 is an abstract operating [...]
astormMagento 2: Serializing a Category Tree as Primitive Types
astormOne thing that keeps biting me in the trnasition from Magento 1 to Magento 2 is that sometimes the etc folder has an area hierarchy. For example, in Magento 1, you system configuration file (respoisble for building out a module’s configuratioin UI) lived in etc/system.xml In Magento 2 this file lives in etc/adminhtml/system.xml [...]

astormThe following steps are, as of October 22, 2015, the quickest way to get a working version of Magento 2 up and running without checking out the source from GitHub. The following will install the merchant beta – which is a stable, mostly feature complete version of Magento 2. There have been changes to the Magento 2 source since [...]
astormHere’s another gotcha to be careful of when using the sales/quote model objects. If you pass the following methods setBillingAddress, setShippingAddress, assignCustomerWithAddressChange an existing quote address object, these methods will reassign the address to the current quote (removing it from the old quote). If you were [...]
astormHere’s another caution sign if you’re using the sales/quote object’s deleteItem or removeItem method. If you look at the code that marks an item for deletion $item->isDeleted(true); if ($item->getHasChildren()) { foreach ($item->getChildren() as $child) { $child->isDeleted(true); } } $parent = [...]
astormI’m working on an in-depth ERP project, and ran into a strange problem where I had a reference to a quote object that refused to delete its items. I could run something like this foreach($quote->getItemsCollection() as $item) { if("item meets my criteria") { $quote->deleteItem($item); } } [...]
astormIf you’ve spent anytime doing Magento 1 module development, you’re probably familiar with the _validateControllerClassName method. This method is where Magento 1 generates and validates paths to possible controller class matches during routing. This method is gone in Magento 2 – partially due to the PSR-0 autoloader [...]
astormIn Magento 1, it was possible to register a global variable with the static registry method. Mage::register('some_var', 'some value'); var_dump(Mage::registry('some_var')); Many extensions, include core Magento extensions, ended up using this from controller action methods to pass variables into the views. While its future is uncertain [...]
