Dual booting arch and win11 Prerequisites Before installing arch we need to do the following things Disk partition We’ll need to make a disk partition in windows 11 before proceeding to make sure both the OS run isolated, this can be done by the following steps Right-click on the Start menu and select Disk Management. Alternatively, you can press Win + X and choose Disk Management from the list. In the Disk Management window, locate the drive you want to partition (usually the C: drive). In my case I’ve installed in D drive on a separate disk Right-click on the drive and select Shrink Volume In the dialog that appears, enter the amount of space to shrink (in MB). This will be the size of the new partition for Arch Linux. Make sure to leave enough space for Windows. In my case I’ve allocated 100 gigs for Arch. Click Shrink. The unallocated space will appear in the Disk Management window. Bios settings Disable Fast Startup Disable secure boot Arch ISO setup Download arch ISO from the official site.

MongoDB Introduction NoSQL databases are non-relational databases that are used to store and retrieve data. MongoDB is a popular NoSQL database that is used to store data in the form of documents. Feature SQL (Relational Databases) NoSQL (Non-Relational Databases) Schema Fixed schema Dynamic schema for unstructured data Scalability Vertical scalability (scale-up by adding more powerful CPU, RAM, SSD) Horizontal scalability (scale-out by adding more servers) Complexity Tables with rows and columns, complex queries with JOINs Document, key-value, wide-column, or graph formats, simpler queries Transactions ACID properties (Atomicity, Consistency, Isolation, Durability) for reliable transactions BASE properties (Basically Available, Soft state, Eventual consistency) less strict than ACID Development Model Mature, with established standards More flexible and evolving rapidly Use Cases Well-suited for complex queries and transactions, e.g., banking systems Well-suited for hierarchical data storage, big data solutions, and real-time web applications Data Integrity High, due to ACID compliance Variable, depending on the specific NoSQL system and its configuration Query Language Structured Query Language (SQL) is standardized No standard; queries are based on the specific NoSQL database system (e.g., MongoDB uses BSON) Relationship Handling Efficient handling of relationships between entities Relationships can be handled, but often less efficiently than SQL databases; denormalization is commonly practiced Installation There are two ways of working with a mongoDB database, one is to run it locally on your machine and the other is to use a cloud service like MongoDB Atlas. For this tutorial, we will be using MongoDB with mongosh and compass installed. ...

Regex via lex and yacc What is a regex? Regular expressions (regex) are patterns used to match character combinations in strings. In JavaScript, regular expressions are also objects. These patterns are used with the exec() and test() methods of RegExp, and with the match(), matchAll(), replace(), search(), and split() methods of String. Why use lex and yacc? Lex and yacc are tools used to generate lexical analyzers and parsers. Lex reads an input stream specifying the lexical analyzer and outputs source code implementing the lexer in C. Yacc reads an input stream specifying the parser and outputs source code implementing the parser in C. Lex and yacc are tools used to generate lexical analyzers and parsers. Lex reads an input stream specifying the lexical analyzer and outputs source code implementing the lexer in C. Yacc reads an input stream specifying the parser and outputs source code implementing the parser in C. ...
