Many people choose Linux as their operating system of choice, making it an invaluable resource for system administrators and software developers alike. Furthermore, its popularity makes it a top choice among servers.
Experience is the best way to understand Linux. Pick one of its major distributions and start using it as your main OS.
1. Digital Trends
Linux has become an indispensable part of modern computing, powering web servers and 90 percent of public cloud workloads alike. Its rapid ascent to become the world’s most widely used OS has transformed the technology industry – it will continue to make waves well into 2023!
Security remains of great concern to IT professionals, yet Linux’ popularity makes it an ideal platform for developing secure, automated and adaptive solutions – hence why it will remain popular choice for cloud environments, IoT solutions as well as desktop/endpoint computing.
Linuxia-based DevOps tools are increasingly making creating, updating and deploying applications easier, while increasing visibility into underlying infrastructure. This trend should drive demand for skilled DevOps engineers. Storage technologies are shifting toward solid state drives and emerging non-volatile memory (NVM) technologies – something Linux is well positioned to take advantage of as it already supports an array of hardware devices.
3. Linux Developers Forum

4. Linux Journals
Journaling makes this task significantly simpler by gathering OS and application logs into one location for easy reading and troubleshooting. Earlier versions of Linux used multiple text files for their log messages, making it hard to match system events to specific log messages when troubleshooting was required. Journaling streamlines this process by consolidating all relevant logs in one central place.
The systemd-journald daemon serves as the journaling daemon, storing entries in structured format that works seamlessly with standard UNIX tools. Furthermore, fast access is offered to entries filtered by date, emitting program PID, UID or service ID; or you can follow new journal entries of specific types using tail -f similar to what tail does on regular log files.
By default, systemd-journald stores journal data both in memory and temporarily under /run/log/journal if it’s non-writable. You can customize its behavior with –persistent, –volatile and –disk-usage options; this last one allowing you to limit volatile storage size to an agreed upon value and even enable compression for reduced disk usage.
