Drupal
A list of technology events that came after Drupal, and that directly or indirectly impacted Drupal. To stay relevant, Drupal had to adjust to many of them.
By tapping into a rich text field such as Body, a toolbar comes up with two tabs with editor buttons below: Format (containing buttons such as Bold, Italic, Left/Right Align, and Lists) and Insert (for Links, Images, and the like).
An overview of the key building blocks to create web services in Drupal. Out of the box, Drupal core can expose raw JSON structures reflecting its internal storage, or it can expose them in HAL. Note: Waterwheel has an optional dependency on JSON API if JSON API methods are invoked through Waterwheel.js.
A design proposal for Automatic Updates. There are updates available for different modules. You can upgrade them immediately using the user interface, or you can let the scheduler run to do it for you.

The problem with disruptive upgrades. People don't upgrade because they don't want to move back into the "suck zone". You have to make it easy to upgrade because users will remember the pain of this upgrade when it comes time for the next one. An upgrade should be worth it so you need a good balance between "upgrade pain" and "added value". (Taken from Why they don't upgrade (and what to do about it)). © Kathy Sierra.
Don't give in to "featuritis" and be the "I rule" product, not the "This thing I bought does everything, but I suck!" product. (Taken from Featuritis verus the Happy User Peak.) © Kathy Sierra.
Users will typically fall into one of the three categories: expert, amateur, or drop-out. The drop-outs decide that during that "I suck at this" phase, it isn't worth continuing. They give up. The amateur made it past the suck threshold, but now they don't want to push for new skills and capabilities. They don't want to suck again. They'll never get past the kick-ass threshold where there is a much greater chance they'll become passionate. (Taken from How to be an expert.) © Kathy Sierra.
The goal of a software application is to get users up the curve as quickly as possible. People get passionate if you help them kick ass with your product. The "time to stop sucking" and "time to first kick-ass" quotients are among the biggest advantages we have in a world where the competition is both fierce and plentiful. Get your users up there faster, and you win. More importantly, it's a way in which we can make a positive impact on the lives of users. (Taken from Attenuation and the suck threshold.) © Kathy Sierra.
The more successful the product or service is, the stronger the pressure to give in to user requests. The more users you have, the more diverse the requests. The worst thing we can do is give in. We have to listen to our users but resist. The overwhelming pull of that right (hate) side slides you closer and closer to the middle. Those who hate it will hate it until you've neutered it into submission and taken away the magic some once loved. (Taken from Don't give in to feature demands.) © Kathy Sierra.
A few examples of organizations that use decoupled Drupal.
The number of pages Drupal can serve per second. Higher bars are better.
The relative performance improvement of Drupal 5's normal database caching compared to Drupal 4.7's database caching. A miss rate of 0% means that all page requests result in a cache hit and that all pages can be served from the database cache. A miss rate of 100% means that all page requests result in a cache miss, and that we had to dynamically generate all pages.
We opened the Drupal 7 development branch in February 2008, and released Drupal 7.0 in January 2011. This graph shows the stacked commit history from beginning to end. I appointed Angie as my Drupal 7 co-maintainer in August 2008 after having been the sole committer for 7 months. The peak around August 2009 (the highest peak) was the first attempted Drupal 7 code freeze. The momentum steadily built up towards the initial code freeze date. Interestingly, we remained most productive during the extended code freeze period ... more code freezes are better than one code freeze? ;-)
I averaged at 3.6 commits per day, whereas Angie's average is 2.6 commits per day (including weekends and holidays).

Most contributed modules currently have no or very few deprecation warnings today. Only a fourth of the modules have 5 or more deprecations.

Under progressive decoupling, the CMS renderer still outputs the skeleton of the page.
In the case of many-headed Drupal, fully decoupled applications can live alongside progressively decoupled pages, whose skeletons are rendered through the CMS.
Traditional ("monolithic") versus fully decoupled ("headless") architectural paradigm.
In a fully decoupled architecture, the theme layer is often ignored altogether, and many content management capabilities are lost, though many clients ingesting data are possible.

PHP5's adoption rate based on data from Nexen.

Drupal's five product strategy tracks. A number of current initiatives is shown on each track.
An example result from the 2016 Drupal product survey. The result shows that in 2016 we decided to focus on "content authors" as the most important persona. Since that survey, we improved Drupal's authoring workflows, media management, layout building, and more.

Phases of development, represented as a funnel gradually getting smaller as fewer and fewer patches are accepted. In Development Phase, anything goes: major new APIs, new features, etc. Feature Completion Phase allows for tying up loose ends on features that are already committed, or significantly in progress. Clean-Up Phase is for stabilization, better consistency, and completing conversions to new APIs. Polish Phase moves to focus on the upgrade path, performance optimization, and improving docs. Finally, during Release Phase, we crank on critical bugs until we release!

Feature branching; each feature is developed in a dedicated branch. A feature branch is only merged into the main branch when it is "shippable". We no longer have to wait for the slowest feature before we can create a new release.
Trunk-based development; all development is done on a single main branch and as a result we can only release as fast as the slowest feature.
A framework can assume responsibility over very little, such as with Backbone, or a great deal of the stack, including the rendering process.
This diagram shows some of the possible front-end experiences that could rely on a single Drupal back-end. In full decoupling, a custom application built using a client-side framework encompasses the entire front-end. In progressive decoupling, JavaScript manipulates an initial state already provided by the theme layer.
The past growth in absolute numbers. The "January 2007"-kink is due to the fact that data for December 2006 is not yet available at this point.
The past growth in relative numbers. In 2005, the number of nodes and comments grew by more than 300%. In 2006, the number of nodes and comments grew by more than 230%.
A growth projection using a polynomial fit (multiple regression). Simply put, the correlation coefficient R-square, is a measure for the quality of the fit. R-square can assume values between 0 and 1, where a value of 1 indicates a perfect fit. Bear in mind that a statistical fit may be anything but an accurate prediction of future growth.

The current YSlow score for the drupal.org front page is 74 (C). YSlow suggests that we reduce the number of CSS background images using CSS sprites, that we use a Content Delivery Network (CDN) like Akamai for delivering static files, and identifies an Apache configuration issue that affects the Entity Tags or ETags of static files. The problem is that, by default, Apache constructs ETags using attributes that make them unique to a specific server. A stock Apache embeds inode numbers in the ETag which dramatically reduces the odds of the validity test succeeding on web sites with multiple servers; the ETags won't match when a browser gets the original component from server A and later tries to validate that component on server B.
