Go Static Typing 'Magic'

As I understand Go more, some of the concepts tend to make my head hurt. Sometimes, innocent examples in various tutorials hide such deep concepts, that it takes a while for me to decode it all.

Here is an example. In various tutorials, pauses are made using time.Sleep().

The first time I saw an example like the following, it made me stop in my tracks.

package main

import (
	"time"
)

func main() {
	time.Sleep(100 * time.Millisecond)
}

The Borg design pattern

How to have shared state between different instance of a class without a singleton pattern.

The ‘Singleton’ DP is all about ensuring that just one instance of a certain class is ever created. It has a catchy name and is thus enormously popular, but it’s NOT a good idea – it displays different sorts of problems in different object-models. What we should really WANT, typically, is to let as many instances be created as necessary, BUT all with shared state. Who cares about identity – it’s state (and behavior) we care about!

Using Python to update a required field while performing a transition in Jira

'Gojira!' by donsolo

This might be a very esoteric topic for most people, but since I could not find information about this anywhere, I decided to document this in a post.

Here is the problem. I use Jira at work, and today, I needed to close a bunch of tickets based on a search result. Now, searching or doing batch operations is simple enough from the browser, but a small detail made the exercise impossible via the web UI.
