Why do we love Linux? Because it is freaking awesome, right. Not only it’s open-source and free, meaning anyone can use it legally without paying to anyone, it’s also driven by millions of volunteers and Linux lovers so that any problem regarding any particular distribution can be easily solved by collective heads all over the globe.
Linux has surely come a long way since its initial release in 1991, from only couple of distributions to more than hundreds of mainstream one’s. Now coming to the point, almost all of us have a spare old computer which we mostly avoid using due to its software compatibility issues.
But with Linux there is always a way to use even the scantiest of computer system. There is an entire line of lightweight Linux distros that are specifically built to target old system. These distros consume considerably less amounts of memory and processor speeds and are highly cost effective. The one acceptable downside is that you won’t be getting those “eye candy” features in your old PC or laptop anymore.
ConnochaetOS is one of the two successors of now discontinued Linux distribution DeLi Linux. ConnochaetOS is designed solely for the purpose of powering personal computers with much limited resources and since that’s the case, it is available for x86 (32 bit) only. It follows the KISS principle (Keep Things Simple, Stupid) and it’s 100% based on Salix OS and Slackware and follow their versioning scheme to keep the update process much simpler.
