Guess Your Birthday with Java: A Fun and Interactive Program.

This is a Java program which asks you to identify whether your birthday appears in five different sets of numbers.
Each set represents some specific range of dates so that every possible day of the month appears in a unique combination of these sets.
Each day of the month can be represented in binary form using 5 bits, which organizes the days in such a way that each day can be identified by checking whether it appears in specific sets.
The program displays each set to the user one by one and reads the user’s response to each set (Yes or No).
Based on the answers, the program adds specific values to a variable day that leverages binary logic and sums up these values to determine the exact day.
The logic behind adding the values 1, 2, 4, 8, and 16 corresponds directly to the binary numbering system, which is the foundation of how computers process and store information.
The method of adding 1, 2, 4, 8, and 16 is tied to the binary system, where each set represents a different bit position in the binary number corresponding to your birthday.
After answering questions for all five sets, the program reveals your birthday, which has been calculated using simple arithmetic.
This is not only a fun way to guess your birthday but also a practical demonstration of how binary logic underpins many applications.
The same logic can be found in real-life applications such as decision trees, binary search algorithms, interactive games, etc.

Thanks for the Memoize

Memoization is a technique used to store the result of a previous execution of a function using the parameters as the key.
By checking if the memoization object contains a value for a given key, we can avoid running the resource intensive function again.
Memoization can be beneficial for optimizing calculations, network throughput, and temporary disk space usage.
However, it is not suitable for non-pure functions or functions with rarely repeated parameters.

Tracking down high memory usage in Node.js

The author discusses their approach in tracking down and solving a memory leak issue in a Node.js library that was causing OOM errors in a dozen services.
The author first tried to understand the code and then attempted to replicate the issue in isolation but was unable to spot the problem.
To capture profiling data, the author connected Chrome DevTools to staging services, capturing heap snapshots over time, and looked for the biggest positive delta, which was happening on the string constructor.
The author narrowed down the scope of the fix to understand when the code was pushing items to and popping them out of an array while leveraging the sentEvents object for producing and consuming events.
The result of the patch drastically reduced memory usage and improved the service's reliability. The patch also reduced the required number of pods handling the same traffic by 50%.
This article serves as a good starting point for anyone interested in learning more about tracking memory issues in Node.js.

6 Common Data Structures in Programming

Data structures are the building blocks of efficient software in programming.
1. Array: Fast access via index, fixed-size (in most languages), used for ordered collections.
2. Linked List: Dynamic size, inefficient random access, used for frequent insertions/deletions.
3. Stack: LIFO structure, useful for backtracking and managing function calls.
4. Queue: FIFO structure, used in scheduling and task management.
5. Hash Table: Optimized for quick lookups, used for dictionaries and caching.
6. Binary Tree: Hierarchical structure, used for organizing data and search algorithms.

Java’s LocalDate.plusDays() Method Explained

Java's plusDays() method in LocalDate class lets you add a specific number of days to a date
It accepts a single argument, the number of days - positive or negative, and returns a new LocalDate object.
It is useful in applications requiring date calculations like scheduling tasks, creating recurring events.
In project planning, use case for plusDays() is adding days to current date
plusDays() can help calculation of future scheduled recurring events like weekly meetings or monthly reminders
You can also subtract days using negative value to look back at historical dates or generating reports that span certain period.
plusDays() also supports adding days conditionally to the current date based on certain business logic or rules.
It has seamless handling of transitions between months and years, making it an excellent tool for accurate long-term date calculations.
While using LocalDate with plusDays(), understanding its relationship with time zones is important.
For scheduling events across different regions or involving multiple time zones, a combination of LocalDate with classes like ZonedDateTime can be used.
