Whether I'm using a laptop my employer assigned to me or a workstation I built from vendor parts, I seem to have an endless capacity to forget my computer's specifications. One of the great things about Linux is its /proc filesystem, a dynamically populated virtual expression of the system's hardware. It's convenient when you want to see the specifics of your CPU (cat /proc/cpuinfo), uptime (cat /proc/uptime), a list of mounted filesystems (ls -R /proc/fs/), and so on.

Java was released in 1995, making it 26 years old as I'm writing this. It was proprietary at first, but in 2007, Java was released as open source under the GPL.

For decades, enterprises have developed business-critical applications on various platforms, including physical servers, virtual machines, and cloud environments. The one thing these applications have in common across industries is they need to be continuously available (24x7x365) to guarantee stability, reliability, and performance, regardless of demand. Therefore, every enterprise must be responsible for the high costs of maintaining an infrastructure (e.g., CPU, memory, disk, networking, etc.) even if actual resource utilization is less than 50%. read more
