It seems that it does not matter what timezone is on the server as long as you have the time set right for the current timezone, know the timezone of the datetime columns that you store, and are aware of the issues with daylight savings time.

On the other hand if you have control of the timezones of the servers you work with then you can have everything set to UTC internally and never worry about timezones and DST.

Here are some notes I collected of how to work with timezones as a form of cheatsheet for myself and others which might influence what timezone the person will choose for his/her server and how he/she will store date and time.

Install and use pip in a local directory without root/sudo access.

By: @saurabhshri

Why?

Many users when are given server access, do not have root (or sudo) privileges and can not simply do sudo apt-get install python-pip . Here's an easy way you can install and use pip without root (or sudo) access in a local directory. Note : This works without easy_install too.

How?

# Description: How to assign VPC addresses to Docker containers associated as secondary IP addresses to an ENI in AWS
# Operating System: Amazon Linux AMI 2016.09.1 (HVM)
# Prerequisites: 
#  - Assign N number of secondary IP addresses to network interface on Docker host
#  - Each new container requires additional assignment of secondary IP addresses
#  - Containers can be launched with --net=none to avoid adding a Docker networked NIC (docker run --net=none -d imageId)
# Credit to https://github.com/jpetazzo/pipework for steps on linking IP address
