Learning Perl - Object Orientation

  • Object Orientation is a common programming paradigm that allows for the creation of objects that encapsulate data and behaviour.
  • Objects in Perl are implemented using packages, which serve as namespaces for grouping related code.
  • To create an object in Perl, a constructor method that blesses a reference into the package is defined.
  • Functions associated with a class in object orientation are called methods in Perl.
  • Accessors are methods that get or set attributes of an object, allowing encapsulation of attribute access.
  • Creating objects in Perl involves using packages, constructor methods, and accessor methods.
  • A Note object example is implemented in Perl with attributes like title, content, and last_changed time.
  • Tests are written to ensure the functionality of the Note object, including instantiation, validation, and accessors.
  • Accessor methods like title, description, and last_changed are implemented for the Note object.
  • The info method is created to return a string with the note's information, combining title, description, and last changed time.

What really happens when you call a function in your code ?

  • Stacks in computing architectures work in a last-in — first-out (LIFO) manner where data is added or removed.
  • The call stack in programming can be compared to handling tasks in a busy kitchen by stacking pending tasks like sticky notes.
  • In programming, functions are pushed onto the call stack when invoked and popped off when their tasks are completed.
  • Recursive functions also operate on the call stack by pushing and popping function calls in a similar manner.

SOLID Principles in C++ Part 1 (Single Responsibility Principle)

  • Single Responsibility Principle (SRP) states that a class should have only one reason to change.
  • Adhering to SRP leads to better modularity, maintainability, and flexibility in software design.
  • Challenges of applying SRP include defining 'responsibility', increased complexity, over-engineering, testing overhead, and impact on design patterns.
  • SRP should be judiciously applied in critical areas of the system for improved maintainability, flexibility, and testability, requiring a good understanding of the domain and experience.

Java series: Caching

  • Caching is a strategy to boost system performance by storing frequently accessed data in a fast-access, volatile database.
  • It helps reduce system latency by storing data in an in-memory cache for faster access.
  • Redis, popular for cloud-native architectures, offers fast performance, low latency, and versatility.
  • Redis can be used as a cache, NoSQL database, message broker, session store, and more.
  • Redis runs in memory, so data may be lost if not configured to persist to disk.
  • To use Redis with Spring Boot, dependencies need to be added in the build.gradle file.
  • Configuring the Java app to connect to Redis involves settings in the application.properties file.
  • Java application examples show how to utilize Redis caching with @Cacheable and @CacheEvict annotations.
  • Customization of caching can be done with additional properties or custom configuration beans in Spring Boot.
  • Redis cache is demonstrated to improve application performance by reducing data retrieval time.

Everything I Wish I Knew About Priority Queues in C++

  • A priority queue in C++ is like a regular queue, where elements are retrieved based on priority rather than arrival order, with default behavior in priority_queue being a max heap.
  • To create a min heap in C++, the priority queue needs to be set up to reverse the priority, ensuring smaller values are treated as higher priority.
  • Custom comparators can be used to sort elements like pairs based on specific values, either by defining a struct or using lambda functions for cleaner implementation.
  • make_heap in C++ efficiently turns a list of elements into a heap with Floyd’s algorithm, offering linear time complexity O(n) for building the heap from the bottom up.

The TC (TIME COMPRESSION) — Time Computing Paradigm: A Totally Not-So-Dumb Idea That Could Change…

  • The Time Compression Paradigm allows machines to compress real-world time into their own hyper-speed internal timeline, enabling them to fast-forward through years of data in just a few days.
  • This concept can revolutionize how tiny devices and embedded systems operate by re-mapping the computer's internal clock, giving them the ability to process huge time spans internally without waiting indefinitely.
  • To implement this idea, a Hyper-Time Processor (HTP) is required, which dynamically stretches and squeezes time using asynchronous logic and power-saving techniques to operate faster internally while pausing in real time.
  • The TC Paradigm challenges traditional computing by offering machines the capability to think longer, learn faster, and operate more efficiently with minimal power consumption, potentially powering the next generation of intelligent devices.
