SDN event October 2017

The SDN – Software Development Network – is a special interest group for dutch developers. Four times a year they organise an event where people present and talk about their passion.

As a member of the SDN you are aware of the latest developments. You are part of a network of professional developers who assist each other in word and deed. This means there is a technical helpdesk at your fingertips so you can book considerable time savings in solving problems. with Google translate

Here are the talks I attended.

Busy Architect’s Guide to DevOps

Ted Neward talks about the beginning of computing and how the DEV and OPS were divided. The difference between the two is the OPS wants to have a stable environment (no change at all) and the DEV wants all new things (change everything). With DEVOPS the two are combined again.

  • an effort (and never done),
  • a culture (not only tools) and
  • a proces (multiple steps)

The talk has been recorded on youtube, see it here.

Agile is tasty. Eat your own dogfood

As an Agile coach Arthur Margonari is asked to introduce Agile in his own company. The backoffice should work more transparent (scrum board), more informed (daily standup), more delivering (sprints), more adapting (retrospective).

In the end the conclusion was that agile can be used whenever people have to work together, not only for software projects.

Busy Developer’s Guide to NodeJS

The main purpose of this talk was to get us “dangerous”. Know there is this runtime called node.js that runs on about every platform, try packages, try coding and maybe break things.

With some code samples Ted Neward showed the pitfalls of using the double equal (==) instead of the triple equal (===). The latter does not typecast. Use the triple equal!

Again an interesting meetup. This time less hardcore coding and tools for me. I liked the non/low-tech subjects in the schedule.

About erictummers

Working in a DevOps team is the best thing that happened to me. I like challenges and sharing the solutions with others. On my blog I’ll mostly post about my work, but expect an occasional home project, productivity tip and tooling review.
