The Zen of Python, by Tim Peters
 
Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
Special cases aren't special enough to break the rules.

Screencasting Framework

The following document is a written account of the Code School screencasting framework. It should be used as a reference of the accompanying screencast on the topic.

Why you should care about screencasting?

You're probably aren't going to take the time to read this document if you're not interested, but there are a lot of nice side effects caused by learning how to create quality screencasts.

1. Communicating more effectively - At Envy Labs we produce screencasts for our clients all the time. Whether it's demoing a new feature or for a presentation for an invester, they're often much more effective and pleasent than a phone call or screen sharing.

Visa requirements for UK conferences.

First you'll want to check if you need a visa to enter the UK.

• Nationals of the EU, Switzerland, and EEA countries will not need a visa, and are free to work and conduct business in the UK.
• Nationals from some designated countries such as USA may travel for tourist or business purposes under a visa exemption. The link above will detail what documents you need to provide in order to travel under a visa exemption.
• Other nationals will need a visa.

The rules for allowable business travel under a visa exemption are covered by the same rules as those travelling under a vistor visa. If you will be travelling under a visa-exemption and the conference is covering your costs in any way you should make sure to read the relevant section below.

kubectl config set-cluster minikube

create deployment yaml

kubectl run hello-world --image=myapp-container-image/k8s:1.0 --port=80 --dry-run -o yaml > myapp-deployment.yaml

create deployment yaml from existing deployment

kubectl get deployment hello-world -o yaml > my-existing-deployment.yaml
