Scrum Guide 2020 updated

The 2020 Scrum Guide™

Available as a PDF here.

Purpose of the Scrum Guide

We developed Scrum in the early 1990s. We wrote the first version of the Scrum Guide in 2010 to help people worldwide understand Scrum. We have evolved the Guide since then through small, functional updates. Together, we stand behind it.

A practical guide to prepare and take the PSM I (Professional Scrum Master 1) certification, from Scrum.org, entirely by yourself (no course required).

How to take the PSM I certification from Scrum.org entirely by yourself

Some people ask me about Scrum.org certifications: what to study, how to apply for the exam and advice for taking it. So I decided to write a guide for those interested in preparing and taking PSM I (Professional Scrum Master) without spending a fortune with training. With discipline, in around a month (or two), you should be ready to take the test.

The advice compiled here came from experienced agile coaches. Worked very well for me and I hope they will also help those who are seeking directions.

Setup a decent environment on Dreamhost Shared Hosting for running python applications

I use Dreamhost shared hosting and everytime I wanto to setup a python website/api/whatever, I struggle crawling over a number of pages for installation instructions and troubleshooting, so I decided to compile myself a guide to get it done properly from scratch.

This manual is in development. I will write it as I go through issues.

Como tirar a certificacao Agil PSM 1 da Scrum.org

Como tirar a certificacao Agil PSM I (scrum.org)

Algumas pessoas me perguntam sobre certificaoes do Scrum.org: o que estudar, como aplicar para a prova e conselhos para realiza-la. Por isso, resolvi escrever este artigo bem pratico sobre a certificacao PSM I (Professional Scrum Master). Com disciplina, em torno de um mes voce estara no ponto para fazer a prova, sem ter que gastar uma fortuna com cursos.

Recebi essas recomendacoes de colegas de trabalho que sao agile coaches extremamente experientes e competentes. Funcionaram muito bem pra mim e espero que ajudem igualmente quem ler este texto.
