What is Power over Ethernet – PoE? What’s the difference between 802.3af and 802.3at (also known as PoE+)? All of the essential information about PoE modes, pinouts and voltages in a single article.

When setting up a reliable network, understanding the Ethernet and related standards is essential. This post covers key topics such as T568A vs T568B, the Category Rating System, UTP vs STP cables and also some tips for installing network cables.

Category 5, Cat5, Cat5e, Cat6, wiring diagrams both for straight through cables, crossover cables, token ring cables in RJ45. As a bonus learn how to build a Ethernet Economizer / Splitter.

In Angular the APP_INITIALIZER is designed for running asynchronous code during the application’s initialization phase – it waits for an observable or promise to complete before running code from your main app component. While this feature is quite useful, adding more than one APP_INITIALIZER will cause them to run in parallel, which makes it difficult to manage dependencies between them.

This is an opinion article where I explain why I believe that the RP2040 chip from the Raspberry Pi Foundation just opened the door for Intel to be an important player on the SBC market. At the same time the Pi Foundation may enter other profitable businesses typically held by FTDI.

In Angular projects, it’s common to use [routerLink] in template elements to handle navigation. While effective, this approach lacks the functionality of “Ctrl + Click” (or “Cmd + Click” on macOS) to open links in a new browser tab. In this post, I’ll share a simple yet effective directive to implement this feature.

In most situations, you would be entering your containers as root, and that’s perfectly reasonable. After all, an unprivileged container ensures that the root inside it will only have root privileges within that container and nowhere else. Sometimes, however, it might be useful to enter a container with a specific user.

This article goes through all the reasons why you might want to replace Proxmox with Incus / LXD and how it could save you from a lot of headaches down the line. While free Proxmox, much like VMWare ESXi was, is a potential disaster waiting to happen.

There are cases where we need LXD / Incus containers to have direct access to the network. In such cases, we want the containers to be assigned an IP address by a router on the network, treating them as individual devices on the network rather than containers inside a host machine that get to the network through NAT.

hdparm.conf can be used to store hdparm settings permanently, ensuring they are automatically applied at every boot. However, for testing purposes, rebooting a machine multiple times can be inconvenient. Fortunately, with a simple command, changes made to the file can be applied live without the need for a system reboot.
