Born for it – How the image of software developers came about
Where did the common image of the socially-awkward, white, male programmer come from?

Data Fetching for Single-Page Apps
Five patterns to help Single Page Applications fetch data from remote sources

CQRS: Command Query Responsibility Segregation (2011)
CQRS (Command Query Responsibility Segregation) is the notion that you can use a different model to update information than the model you use to read information

Sacrificial Architecture
Sometimes it's a good thing to be writing code that you expect to throw away in a couple of years time.
66
Microservices
Defining the microservices architectural style by describing their nine common characteristics

The LMAX Architecture (2011)
LMAX is a retail financial trading system that can handle that can 6 million orders per second on a single JVM thread. The business logic runs in-memory surrounded by disruptors using event sourcing.

Is Design Dead? (2004)
The rise of agile methods (particularly XP) makes some people wonder if there's any role left for software design. I argue that this change shifts from planned to evolutionary design.
69
Event Sourcing (2005)
Capture all changes to an application state as a sequence of events.

Why are good developers so wary of agentic development?
Good developers’ caution about agentic development comes from knowing that built isn’t the same as working in production.
71
OrmHate
Object-Relational Mappers get a lot of hate from people who misjudge the complexities of the task.

The Lies that can Undermine Democracy
Recent events highlight our need to take serious measures to counter lies that are undermining democracies.

Two Hard Things (2009)
There are only two hard things in Computer Science: cache invalidation and naming things -- Phil Karlton (bonus variations on the page)

Mocks Aren't Stubs (2007)
Explaining the difference between Mock Objects and Stubs (together with other forms of Test Double). Also the difference between classical and mockist styles of unit testing.
76
Feature Toggles
Feature Flags can be categorized into several buckets; manage each appropriately. Smart implementation can help constrain complexity.
77
bliki: Bounded Context
Don't try to build a single, unified model for a large domain. Instead DDD advises us to divide such a domain into many bounded contexts with explicit relationships between them.
78
Continuous Integration
Every developer integrates their work into mainline at least every day.
79
bliki: Strangler Fig
Inspired by the strangler figs in Australia, a strangler fig application gradually draws behavior out of its host legacy application
80
bliki: Frequency Reduces Difficulty
"If it hurts - do it more often". Good advice if the amount of pain raises exponentially with the time between actions, such as for integrating software.
81
bliki: Test Pyramid
Write most of your tests at a low level (unit tests) with a few broad-stack tests, eg via UI. UI tests tend to be fragile and slow.
82
Inversion of Control Containers and the Dependency Injection pattern
Explaining the Dependency Injection pattern, by contrasting it with Service Locator. The choice between them is less important than the principle of separating configuration from use.
83
bliki: Anemic Domain Model
If you use an object-oriented domain model, and you don't put behavior in your objects, you're missing out on most of the benefits of that pattern.

The Practical Test Pyramid
Find out what kinds of automated tests you should implement for your application and learn by examples what these tests could look like.
