Slackel 7.4

Before he couldn’t work with Arch, he couldn’t work with Slackware, which is why Mayank Sharma jumps at everything that mentions the venerable distro

RebornOS 2020.12.28

The constant deluge of Arch-based distros can put anyone to sleep, but this one makes Mayank Sharma wake up from his slumber

With perennial fat fingers, Mayank Sharma has been messing with hard disks long enough to know that good rescue tools are worth their weight in gold

Mayank Sharma has enjoyed one Arch-based distribution this month, but will lightning strike twice or has he been taken in by the distro’s tall claims?

Wasteland 3

Management simply hates weirdos and snow, so this is a bad time of year for them and they’re taking it out on Jody Macgregor

Game engines

There’s never been a better time to get into game development on Linux. Michael Reed puts five capable engines under the microscope

How free is it?

There are different kinds of free…

Community and support

A game engine is useless without a way of learning how to use it

Programming environment and GUI

A difficult environment can lead to eventual loss of interest

2D workflow and features

Top down, overhead, side on or something else?

3D workflow and features

How easy is it to create a world to move around in?

Extras

Anything that makes it stand out from the rest?

Ease of use

This is relative because some engines are more capable in terms of what they can do

The Verdict

BETTER VIRTUAL MACHINES

Forget about the draconian confines of reality and immerse yourself (well, your computing) in a virtual world. Jonni Bidwell’s here with a machines-inside-machines extravaganza

A virtual history

Datacentres are full of VMs, but why and how did they get that way?

QEMU, KVM and the other ones

Learn about virtualising the Linux way, with libvir t and Virtual Machine Manager, and jokes about Inception

Contain yourself

Containerisation is even more of an ugly word than virtualisation, but it’s a big deal too. A Docker whale-sized big deal, as we’ll discover…
