Virtualisation

Wow, you learn something new everyday. I’ve just found out about two variations on virtualisation. Linux Containers (LXC) and Vagrant.

Linux Containers (LXC) is known as OS-level virtualisation, meaning the kernel looks after the virtualisation, and there is no need for some extra management software along the lines of VMWare or Virtualbox. The guest OSes run as containers, similar to chroot jails, and all containers, including the main one you booted from, share the same kernel and resources as your main container. As such, LXC only supports linux-based guest OSes. You can’t (easily, anyway) run Windows under LXC. Homepage, Wikipedia.

Vagrant is a strange one. It sells itself as being a way to keep development environments consistent, and I can understand why — if you have a team of people all with a VM of the same OS, but end with different results because they have tinkered with the settings on the VM OS, Vagrant prevents this by keeping the core one in the cloud, and each time the machine is started up, it checks itself against the cloud version, updating itself if needed. That guarantees consistency. Homepage, Wikipedia.

I haven’t tried both of these tools in great detail yet, but here’s some related links for you to check out:

These employees really do love their boss: watch their amazing final farewell to him

Originally posted on Metro:

Mark Stebba served as CEO of the fashion company, Net a Porter, for the last 11 years and is standing down.

As he entered the London head office, he was welcomed by a gospel preacher, net ball team and his staff lining corridors with placards of his face and his name.

While they clapped, a parody version of Aloe Blacc’s hit song ‘The Man’ was sang to him by a gospel choir.

The bemused chief executive, took it all in his stride, even when he saw staff celebrating him via video link from offices in Manhattan, New Jersey, Hong Kong and Shanghai.

Like all good bosses, Mr Stebba knew how to reply to such gestures: ‘Thank you very much everybody, I’m a bit overwhelmed, but…how about getting back to work.’

Everyone, quit your job, start packing your bags and prepping for a flight to Japan, stat.

Tashirojima, an island off the east coast of Japan, is completely and utterly overrun by cats and it’s just like being a crazy cat lady in the best possible way ever.

With only 100 humans on the island, the population is mostly made up of incredibly cute stray cats – which thrive because locals believe that feeding them will bring them good wealth and fortune. Bless.

It is also prohibited to bring dogs on the island, naturally.

Cats were originally kept on the island because they are a natural predator for silk worms, important given that silk was made on the island.

But now, now it’s just so cat-mental that it’s become a tourist hub.

Also, oysters are a local produce of the island, so you know you’ll…

Game (And Software) Release Stages

This is a Google Developers episode detailing how best to avoid releasing broken or defective games on Google Play. It speaks of three release stages: Alpha, Beta, and Canary/Staged Rollout. Alpha and Beta, almost all people are aware of. But Canary/Staged Rollout is a new term for me, but makes a lot of sense.

If you develop and/or release software, this is probably worth a watch.
