Docker Docker


Docker is known worldwide as a popular application containerization platform. It makes projects more efficient, faster, scalable, easy to debug, simple, and lightweight. It removes machine-based dependencies, like any application that runs on an X machine but cannot run on a Y machine. Docker has huge community support that makes it more reliable and convenient.

There are some common terminology that are ambiguous. They are:
  • Docker Hub is an open-source repository hub where container images are stored.
  • Docker Compose is a tool that defines and runs multi-container applications.
  • Docker Engine builds and containerizes applications.
  • Docker Desktop is a GUI-based docker maintaining tool.
  • Docker Build Cloud is a cloud-based service that builds container images on a cloud infrastructure.
Why we should use docker?
  • It makes applications scalable, flexible, and portable to run.
  • It provides consistent environments which is important for application testing, development, teamwork, security, and performance.
  • This is lightweight architecture so it is very resource efficient in any machine.
  • Users can run multiple versions of applications at a time, without interrupting them each other.

Poridhi: Stacks & Queues

  Stacks & Queues related problems: This collection of solutions tackles three classic problems often encountered in technical interviews and competitive programming. The Valid Parentheses problem checks whether a string has properly matched and ordered brackets using a stack. The Sliding Window Maximum efficiently finds the maximum value in every window of size k across an array using a deque, a popular sliding window pattern that ensures optimal performance. The Stock Span Problem simulates a real-world stock analysis scenario and calculates the number of consecutive days before today for which the stock price was less than or equal to today's, also utilizing a stack for efficient computation. These problems test understanding of stacks, queues, and sliding window techniques. ✅ Valid Parentheses def isValid ( s: str ) -> bool : stack = [] mapping = { ')' : '(' , '}' : '{' , ']' : '[' } for char in s: ...

Data Recovery: DevOps pre-state learning

  Data Backup Data backup is the practice of copying data from a primary to a secondary location, to protect it in case of equipment failure, cyberattack, natural disaster or other data loss events. This can include documents, media files, configuration files, machine images, operating systems, and registry files. Essentially, any data that we want to preserve can be stored as backup data. Data Restore Data restore is the process of copying backup data from secondary storage and restoring it to its original location or a new location. A restore is performed to return data that has been lost, stolen or damaged to its original condition or to move data to a new location. Pilot Light A pilot light approach minimizes the ongoing cost of disaster recovery by minimizing the active resources, and simplifies recovery at the time of a disaster because the core infrastructure requirements are all in place. Warm Standby The warm standby approach involves ensuring that there is a scaled down, ...

Poridhi: Basic Programming & Math

Basic Programming and math related problems: Extracting digits means breaking a number like 1234 into [1, 2, 3, 4], often using string conversion or modulo/division. Counting digits involves finding how many digits are in a number using length of a string or repeated division. Reversing an integer flips its digits (e.g., 123 becomes 321), with care for signs and 32-bit limits. A palindrome number reads the same forward and backward, often checked by comparing the original and reversed number. Armstrong numbers are those equal to the sum of their digits each raised to the number of digits, like 153 = 1³ + 5³ + 3³. To find the sum of all divisors of a number, loop through integers and check which divide the number without a remainder. Prime numbers are only divisible by 1 and themselves, and checking up to the square root is efficient. GCD, the greatest common divisor of two numbers, can be found using a simple loop or more efficiently with the Euclidean algorithm, which uses repeated mo...
