Agile Practices

---

No company or project in the software industry today without the word agile in some form.

I believe that the best form of agile is the simple form and that we should not ignore the past (before agile), as even the waterfall methods does contain techniques which is worth take learnings from.

DevOps

---

DevOps is more than CI and CD, DevOps is a culture.

The Three Ways:

• The First Way: Flow/Systems Thinking
• The Second Way: Amplify Feedback Loops
• The Third Way: Culture of Continual Experimentation and Learning

The five ideals:

• The First Ideal: Locality and Simplicity
• The Second Ideal: Focus, Flow, and Joy
• The Third Ideal: Improvement of Daily Work
• The Fourth Ideal: Psychological Safety
• The Fifth Ideal: Customer Focus

DevSecOps or SecDevOps

As security should be an integrated part of DevOps, so the “Sec” should not be needed.

DevSecOps is the cross section between technology, humans and security,

Teaching

---

Personally I think that a better word for teaching is “Knowledge facilitation”, or at least its a more descriptive word to how I think teaching should be carried out.

I teach in many areas of of software development, I prefer my classes to be hands-on with either assignments or projects and required the students to seek information on their own.

Courses I have taught:

• Cyber security
• Web-development backend (.NET)
• Data access using .NET
• Produce and deliver software
• Development of cloud based applications

The outcome of teaching is learning, and learning is the reflection of what you know, it’s about making sense of an experience or knowledge and incorporating this into our own mental model of the world or software for that sake. We build our learning our existing knowledge and experience, so no student is alike, neither before or after the teaching session.

In my opinion is the border between teaching and play extremely thin, and if teaching is done right is it play, but if work is done right is it also play. It is reasonable to conclude that enjoyment and learning are two sides of the same coin.

Documentation

How to write documentation which is useful

Since the agile revolution has the word “documentation” developed into a negatively charged word, making documentation a thing is only done if required by the business and a thing that most developers dislike.

On 25 May 2018 the General Data Protection Regulation (GDPR) was implemented in EU, for many this is synonymous with cookie content, but this is not the whole story as GDPR indirectly put a increases the level of needed documentation.

The best kind of documentation is in my opinion documentation which is done either without any big effort (or without feeling like it’s documentation) or documentation which is generated. But the most important documentation is the well produced documentation which shows the big picture and introduce to the project.

Everybody in a team need to take active part in the production of documentation.

Security

---

Cyber security is important, and we are obligated to in any application to do our best.

It is worth noting that even is if we build the most secure application is the world, is no chain stronger than the weakest join, and in the same sense if the os/server/infrastructure containing our secure application is not secured is …

Play

---

By nature are we humans build to strive for new learning, and as children we accomplish this through play. Play makes us feel alive and helps us discover new limits and new possibilities

“When we stop playing, we stop developing, and when that happens the laws of entropy take over - things fall apart.”

I believe that we should start to embrace play at work, this does not mean that our offices should be full of toys, but it means that we should start to on purpose make activities playful.

An activity is playful if it is:

1. Fully absorbing
2. Intrinsically motivated
3. Include elements of uncertainty and surprise
4. If it motivates a sense of illusion or exaggeration

Within software development we often talk about developers being “in the zone”, in my opinion this is actually another way to phrase that the developer is “playing”. While it is our nature to keep playing as we grow, adults often or suppress the use of this transformative power, and we risk to loos out on a lot of energy and imagination which playing enables. Even worse does many organizations have some very unhealthy and brain-unfriendly working patterns when it comes to demanding that their employees be constantly “on”.

Imagination is our mental capacity to conceive of what is not, and one can argue that if imagination is the ability to conceive what is not, then creativity is imagination applied. And our imagination is like a muscle which needs to be constantly be trained and challenged.

Ethics

---

It’s hard to put a finger on what is ethical software development, but in the end it comes down to the users and how we control the behavior of the user.

It’s not the responsibility of the individual developer to solve all ethicals issues in an application, but it is in my opinion the responsibility of the individual developer to raise the issue when the solution they are working on are containing unethical elements.
