Link: List Of Tools To Monitor The Health Of Your Linux System

Achieving good performance from a computer or network is an important part of system administration.The monitoring and maintenance of the system is the most important task listed in the checklists for daily tasks of a system and network administrator. There are many commands line utilities created for this purpose.

This article describes how you can monitor services and attributes of Linux/UNIX servers using command line, such as:

  • CPU load
  • Bandwidth
  • Memory usage
  • Disk usage
  • Logged in users
  • Running processes
  • etc.

Let’s start.

Link: Deprecated Linux networking commands and their replacements

In my article detailing the command line utilities available for configuring and troubleshooting network properties on Windows and Linux, I mentioned some Linux tools that, while still included and functional in many Linux distributions, are actually considered deprecated and therefore should be phased out in favor of more modern replacements.

Specifically, the deprecated Linux networking commands in question are: arp, ifconfig, iptunnel, iwconfig, nameif, netstat, and route. …..

Link: How to Check the True Bitrate of Your Audio Files

Files are generally assessed on their bitrate. A 320kbps MP3 is obviously better than a 128kbps version, right? Ordinarily, yes. But it’s not hard to bluff the bitrate and mislead listeners through “upscaling.” In fact, upscaling can sometimes damage audio quality.

Audio encoding is a complex process, and Stack Overflow user “vaxquis” provides an intricate explanation of how it works. If you find the subject interesting, his explanation is one of the clearest available.

How do you sort the wheat from the chaff?
