My 2 days Journey on moving services to a swarm
I work for starsellersworld.com, I wanted my company start to use tool for tracking project development in a centralized way, Jira was expensive as resource, and I can not ask such a step, so I asked a machine were to run Redmine. Then it cames the gogs, and, after little time, Jenkins. A number of […]
I stopped the data flow – on React best practices
Reading the interesting article from Dan Abramov:https://overreacted.io/writing-resilient-components/ I stopped at memoization. I did not know this technic before, but simply because nobody care so much about names before functional programming.
