Working the right way, by knowing all the wrong ways

44 views

Published on

Software development is a strange mixture of work and art. We do not only write code, but we make art as writers create their masterpieces. Your habits reflect on your daily work and shape how you approach new tasks. The main problem of bad habits, aside of wasting your time and lowering your motivation, is that rather often you don’t even know about them. I will talk about bad habits by sharing with you all of the bad practices that I remember from my past and current projects. I will talk about what helps me write better, what motivates me and what prevents me from doing so. I will tell you how I started with Delphi, PHP and JAVA, how I hated JavaScript and how I love it now. We will even briefly talk about DevOPS and how I had to develop a torrent client in Python. I’ll share how I manage to learn new things, despite my uncanny laziness for reading.

  13. 13. Open environment ■ You can help the others imrpove ■ Others WILL help you improve ■ You can’t see all the mistakes, that you make ■ Share your thoughts out loud. Telepathy is a fiction.
  14. 14. The “Are we there yet” driven development
  15. 15. “Are we there yet” ■ Report regularly and clearly. ■ Think for the other non-tech members of the crew. ■ They will twist the system, to get the info!

  29. 29. ■ It’s your project ■ It’s your promise ■ It’s your code ■ It’s not a “hit and run” job. You have to support it. Be responsible

  31. 31. Don’t blindly follow the fassion!
  32. 32. The research half-days
  33. 33. ■ JIRA is for tasks, not for showing off how good you are! ■ IDE vs Editor - Noone cares ■ How quickly do you do code refactoring? ■ Are you so proud that you know the project by heart? ■ Don’t remember! Recreate! Know your tools

  35. 35. Always estimate your work
