No need to reboot

This week in a -almost- desperate way of trying to solve an effect because no root cause is detected a machine reboot has been scheduled. When I was starting at Linux system administration I realized that there’s no need to reboot s Linux system in general, only in very specific scenarios.

Although production environments at job are now over a year of uptime I feel particularly proud that a humble -and quite old- RaspberryPi for testing purposes at home has reached 76 days of uptime. It’s needs to be told that I never take care of power supply and reboot that little one every time this is the shortest path to solve anything in there.

State of art for RHEL clones

A short post just to share a grid with nowadays alternatives to RHEL clones after IBM decision on CentOS.

In order to keep it simple I don’t link to the downloads, you’ll find each download on its own page. Neither I extend my opinion, just a very minimal note. Longer explanations deserves its own post.

UPDATE: I forget to say that the best RHEL clone is RHEL itself. Red Hat should have published this before announcing the changes in CentOS but anyway I consider this a very good idea; you may use a real RHEL up to 16 production machines. A former Red Hat program for Individual Developer was available and it’s going to be substitute by this program.

Fedora on a white macbook

A work mate offered me his old white macbook. As long as Apple decides about the so called programmed obsolescence, he installed a Linux to stay secure and fully operative.

He use to run Linux Mint, which is a good distro for the desktop and end-user.

He asked what distro I use, and so, he will install it to me saving my time. The funny side of the story is that when he told me he was surprised about how fast and smooth Fedora performs on the same hardware. Good point for Fedora team.

Plan B, failure, loosers and winners

You start thinking about Plan B and every thought that you put into Plan B you’re taking away now that thought and that energy from playing a and and it’s very important to understand that we function better if there is no safety net because Plan B becomes a safety net.

It says that if I fal then I fall and I get picked up and I have something else there that was they will protect me and that’s not good because people perform better when there’s no safety net people perform better in sports and everything else if you don’t have a plan B.

To me it is very dangerous to have a plan B because you’re cutting yourself off from the chance of really succeeding and the reason one of the main reasons why people want to have a plan B is because they are worried about failing.

What is if I fail? then I don’t have anything else. Well let me tell you something: don’t be afraid of failing, because there’s nothing wrong with failing. You have to fail in order to climb that ladder there’s no one that doesn’t fail. We all fail it’s okay. What is not okay is that when you fail you stay down. Whoever stays down is a loser and winners will fail and get up fail and get up fail and get up you always get up that is a winner that is a winner
