Linux Archives

Over 80% is running on some form of Linux – so does your Mac and you iPhone. Sometimes we have to get our hands dirty on the command line – it makes you feel like a proper hacker.

Here are some pointers I picked up on my journey.

How to enable WiFi on a MacBook Pro in Fedora

I’ve recently given Fedora a spin on my MacBook Pro (2011 vintage). While it installed fine, the WiFi card inside it was not recognised by default. From what I understand there is a Linux driver for the card, but the software around it is so restrictive that the driver cannot be included in the official … Read more

How to install Unreal Engine 4 on CentOS 7

I usually write about Unreal Engine over on my other website, because it tackles more 3D related topics – but compiling the engine from source is a bit more “blood and gore” thing so I thought it best placed here with all the other Linux topics. Anyway… Today we’re installing Unreal Engine on a CentOS … Read more

How to install an rpm file on CentOS

On extremely rare occasions (LOL) we get precompiled binaires we can install on our Linux systems. Depending on the distributions, we may end up with an rpm file. I always forget how to install them when this happens – probably it happens so very rarely. Here’s how we can do that. Installing rpm files with … Read more

Removing the latest Kernel in CentOS

I’ve had a power cut recently, which seems to have corrupted the latest Kernel I have installed on my CentOS 6 server. I can boot into the previous one just fine, but of course if I forget to make a choice on startup, the server doesn’t start up. That’s annoying.

Thankfully there are ways to either fix the latest version, remove it, and even exclude a particular version from future updates. Here’s what worked for me on CentOS 6:

How to install Blender on CentOS 7

I’ve been trying to build Blender from source on CentOS for many years, but never had any luck making it work. There was always one package missing, or something else that needed to be configured. Depressed and resentful, I gave up and never got a chance to try Blender on CentOS.

Recently, the Blender Devs have started releasing a pre-compiled version of Blender for CentOS for download. This should work on RHEL and Fedora just as well. Huzzah!

With a fresh installation of CentOS looking at me from my old Samsung Q330 laptop, I thought I’d try it out. It works great! Here’s what I had to do to make it work, step by step.

How to revert a yum update on CentOS

Every so often, a yum update brings unexpected results with it, like services no longer working due to spurious error messages that don’t tell you what’s actually wrong. This only very rarely happens though, and we may need to revert to the state of our system before such an update took place. Thankfully, yum has … Read more

How to split a ZIP file into multiple parts on macOS and Linux

ZIP files can get quite large, depending on the amount of data we’re ZIPping up there. Having one huge file may not always be desirable, for example when making hard copies onto disk or tape media, or when upload limitations force the use of smaller files. Thankfully, the clever little ZIP utility has a handy … Read more
