VLANS One of the technologies used to improve network performance is the separation of large broadcast domains into smaller ones. This article describes how to configure, manage, and troubleshoot VLANs and VLAN trunks. It will also explore security considerations and strategies related to VLANs and trunks, and best practices for VLAN design. Networking
MAC Address Complete Guide MAC addresses play a crucial role in the data link layer (Layer 2) of the Open Systems Interconnection (OSI) model. MAC addresses are used to send Ethernet frames between two stations in the same local area network. Each station has a unique MAC address that is used to identify who is the sender (source mac address) and who the receiver (destination mac address) is. Networking
Linux TCP keepalive TCP keepalive settings play a crucial role in network performance and resource management. By following the best practices and adjusting the settings to suit your specific needs, you can optimize your system’s ability to detect and clean up stale network connections while maintaining optimal performance.

Relational Databases Explained How Relational Databases Work. This post talks about how indexes and transactions work on the inside of relational databases. Architecture Databases
Preloading responsive images This article gives me an opportunity to discuss two of my favorite things: responsive images and preload. As someone who was heavily involved in developing both of those features, I'm super excited to see them working together! Development
Fallacies of Distributed Systems Fallacies of distributed systems are a set of assertions made by L Peter Deutsch and others at Sun Microsystems describing false assumptions that programmers new to distributed applications invariably make. Architecture
Redis Explained A deep technical dive into all things Redis. Covering various Redis topologies, data persistence and process forking. Architecture
Database Sharding Explained More features, active users, and data are collected daily. Your database is slowing your application. Many people don't understand database sharding, which could solve their difficulties. This article explains database sharding, its benefits, including how to use it and when not to.

How To Find Out Hard Disk Specs / Details on Linux Linux comes with various commands to find out information about your hard drive. I recommend hdparm command, which provides a command-line interface to various hard disk ioctls supported by the stock Linux ATA/IDE device driver subsystem. This command reads/request identification information such as disk size, description, and much more directly from the drive, which is displayed in a new expanded format. Let us see various Linux disk info commands to print hard disk drive details on screen. Linux Linux Utilities
Ethernet Frame Header In computer networking, an Ethernet frame is a data link layer protocol data unit and uses the underlying Ethernet physical layer transport mechanisms. In other words, a data unit on an Ethernet link transports an Ethernet frame as its payload. Networking
