Data structure tutorial 9: Circular Queues Data structure introduction and Implementation using arrays.

Circular Queue uses a data structure (array or linked list) to allow insertion and removal of elements from both the ends (front and rear end).
In this article, we understand the introduction to Circular Queue Data Structure, Formula to calculate to insert elements, Understanding inserting elements with an example, and Implementation of Circular Queue using arrays.
In Circular Queue, the front will be pointing at 0 and rear pointer will be pointing at the maximum index size of the queue.
When an element is inserted at the rear end, rear_end = (rear_end + 1) % MAX_QUEUE_SIZE; similarly, when an element is deleted from front_ end front_end = (front_end + 1) % MAX_QUEUE_SIZE; are the formula to calculate the index.
Depending upon the result, the rear pointer will update accordingly.
Circular queue, we will be utilizing the space efficiently.
Data structure uses an array with operations Insert(), Delete(), Display().
The Insert() function adds an element at the rear end and Delete() function deletes element from the front end.
Display() function shows the content of the queue.
Code implementation of Circular Queue using arrays includes InsertQueue(), DeleteQueue(), and DisplayQueue() functions.

This Runtime Meta-Programming Pattern in Python is Interesting

The current builder interface in the UI framework Zenaura was found to be complex and unappealing.
The goal was to simplify the interface and provide users with a cleaner syntax for creating UI elements.
A dynamically generated code approach was explored to achieve this, but it lacked auto-completion and usability.
The approach offers flexibility in adapting to changes in HTML tags, but usability is compromised.

Migrating from Azure Database for PostgreSQL to Neon

Azure Database for PostgreSQL can now be migrated easily to Neon, which offers serverless architecture, auto-scaling capabilities, and actual data storage billing. The migration process can be done using the utility tool pg_dump and pg_restore that can efficiently backup and restore a Postgres database. An accessible step-by-step guide is available for developers. Robust solutions that address scalability, complex dependencies, or strict security requirements are also available. Post-migration verification guarantees the integrity of data moved between the databases.
Azure Database for PostgreSQL offers the great Postgres features that many developers are familiar with while managing infrastructure for them. However, the fixed capacity that requires some overprovisioning could lead to heightened costs. Neon offers serverless architecture, which automatically scales compute resources to zero when idle and allows billing based on actual data size instead of provisioned capacity.
The step-by-step guide on how to easily migrate from Azure Database for PostgreSQL to Neon can be done by the tool pg_dump and pg_restore backed-up and restored a Postgres database that maintains dependencies and referential integrity. This process remains the most reliable way of migration, however, other options exist as well. For example, logical replication can be used for migrations of databases in the terabyte range.
Complex dependencies in Postgres that often create circular migration challenges include, for example, cross-schema references and custom extensions that don't have direct equivalents in the target system. A three-phase migration approach addresses the issue: pre-schema, schema, and post-schema. Security and Compliance-related challenges can be addressed by implementing a security-first migration pattern that includes tasks such as export and map of all roles and permissions.
The migration from Azure Database for PostgreSQL to Neon might take some planning, but the long-term advantages make it worthwhile. Neon's serverless architecture offers automatic scaling, capacity that matches real usage, and smarter cost efficiency.
Developers using Postgres features through Azure Database for PostgreSQL have the option to migrate to Neon's serverless architecture. The process is smooth, and robust solutions that address potential scalability, complex dependency, and strict security-related issues are also available. The migration options include logical replication and a three-stage migration approach method.
The method to migrate easily from Azure Database for PostgreSQL to Neon is using the utility tool pg_dump and pg_restore. Both backup and restore operations handle dependencies and referential integrity efficiently. Post-migration verification safeguards guarantee data integrity between the databases.
With Neon, one can enjoy Postgres features with the added benefits of serverless architecture, auto-scaling capabilities, and smarter cost efficiency. Migrating from Azure Database for PostgreSQL to Neon is an advantage worth taking, considering its familiar Postgres experience and convenience.
Large data volumes, complex dependencies, and compliance and security requirements create migration challenges when moving from Azure Database for PostgreSQL to Neon. Logical replication and a three-phase migration approach are viable solutions. A security-first migration pattern that addresses security policies, compliance requirements, audit logging, is a good practice to prevent unauthorized access during migration.
The step-by-step guide available for developers who need to migrate from Azure Database for PostgreSQL to Neon involves using the utility tool pg_dump and pg_restore, backed-up, and restored the Postgres database. The method maintains referential integrity and handles dependencies efficiently. Migrating to Neon offers smarter cost efficiency, serverless architecture, and automatic scaling capacity, providing a better user experience.
The migration from Azure Database for PostgreSQL to Neon opens up serverless architecture opportunities that are not available before.

Data structure tutorial 4: Doubly Linked List [DLL]

Doubly Linked List is a special data structure, which is a collection of zero or more nodes.
Each node is made up of 3 parts, prev_link + data + next_link.
In a Doubly Linked List, we need to store the address information for the previous node and the next node.
The DLL operations include inserting an element at the rear, deleting an element with a given key value, searching for an element and displaying all the data.
The implementation of DLL includes defining structures for nodes, head pointer, and the 4 defined operations.
The C++ code presented inserts, deletes, searches and displays elements in a DLL.
When inserting elements at the rear, we check if head node is NULL.
If the head element is not NULL, we use the next pointer to move to the end of the list to add the element.
To delete an element we move the pointer temp to the element with that key, then update pointers for adjacent nodes before deleting the temp node.
To search an element we move the temp pointer to the head and check if the data is the same as key.
