You have a document model with paragraphs, images, and tables. Now you need to export it to HTML. Then PDF. Then calculate word counts. Then extract all image references. Each new requirement means…
Read more →When you write obj = MyClass() in Python, you’re triggering a two-phase process that most developers never think about. First, __new__ allocates memory and creates the raw object. Then,…
The Prototype pattern is a creational design pattern that creates new objects by copying existing instances rather than invoking constructors. Instead of writing new ExpensiveObject() and paying…
Some objects are expensive to create. Database connections require network round-trips, authentication handshakes, and protocol negotiation. Thread creation involves kernel calls and stack…
Read more →Serialization converts objects into a format suitable for storage or transmission. Deserialization reverses this process, reconstructing objects from that data. The problem? When your application…
Read more →Object detection goes beyond image classification by answering two questions simultaneously: ‘What objects are in this image?’ and ‘Where are they located?’ While a classifier outputs a single label…
Read more →Object detection goes beyond image classification by not only identifying what objects are present in an image, but also where they are located. While a classifier might tell you ’this image contains…
Read more →The sync.Pool type in Go’s standard library provides a mechanism for reusing objects across goroutines, reducing the burden on the garbage collector. Every time you allocate memory in Go, you’re…
The Flyweight pattern is a structural design pattern from the Gang of Four catalog that addresses a specific problem: how do you efficiently support large numbers of fine-grained objects without…
Read more →Every time you write new ConcreteClass(), you’re welding your code to that specific implementation. This seems harmless in small applications, but it creates brittle architectures that resist…
Every developer has encountered code like this:
