Art

The other week I went on vacation with my family. We flew to Switzerland and had a really great time. I took the big camera to make gorgeous shots of my wife, my baby daughter and the Alps. The iPhone camera is great but pales in comparison to a professional camera. As I am no great photographer you can see this in every shot. But still, the pictures I made with the DSLR are just better. When using a big camera I always try to take more time for the composition of the shot. I use the lens, different focus spots and depth of field way more than when shooting with my phone.

Where's your GPS

Imagine you are about to go on a trip. Perhaps with your partner or some friends. You want to take the car into the woods, to a place you have never been. The vacation spot has a nice house with a pool and a barbecue. The woman you rent it from stocked the fridge with cold drinks. And they have water beds. And WIFI! IN THE WOODS!

The four types of documentation

You probably already noticed from the title of this letter, the topic of documentation is still important to me. Now that I began spending time with it I notice the many different aspects of documentation. And there’s more than I thought.

Today I want to share a resource with you that taught me about the four different levels/types of docs. I didn’t even know that there were four levels, or why they mattered. They start with something very important:

It doesn’t matter how good your software is, because if the documentation is not good enough, people will not use it.

Stardom (continued)

I received great replies to my letter last week. I want to quote two for you today.

First is Jacob Wyke on the question why these people become some kinds of star for you an me.

I think its because they teach people things, and so generations of developers look up to them as they taught them things.

Stardom

Do we have software development stars? I was wondering. We have people like David Heinemeier-Hanson who created Rails. We have Martin Fowler and Uncle Bob, among several others. Are these stars?

Code Quality through high-quality docs

Hi friend.

I am going to drum the quality drum again. This is a big topic and I know for a fact that I haven’t even scratched the surface of what there is to say about it.

About a month ago I wrote

I’d like to admit, I never had a mentor or teacher who showed me how to properly document software. It was all learning by doing. If you don’t mind, I’ll take some future episodes of this newsletter to document (see what I did there? 👅) my findings and further thoughts about this topic.

This is one of these letters about documentation. My knowledge hasn’t grown by as much as I would have loved, but I read some interesting articles about docs. I want to share these with you.

Teamwork

Hi friend.

You might remember that I told you about my “type”, the INTJ (Architect). Reader Gary wrote in to share his thoughts about that (quoted with permission):

Processes for achieving quality

Hi friend.

So I’ve been busy at my client’s today. I had to implement a sidebar navigation with React. I did something like that a few years ago already and could now redo it for this client. This was great because I could build on my knowledge from the last years. And that’s why I got totally lost in time… I bet you understand. 😉

Last week we talked about quality, and how you could measure it in other’s projects but also your own. Today I want to think about how we can achieve a certain level of quality. But more important: How can we make sure we always achieve this level in our projects.

Quality (continued)

Hi friend.

My brother reads these emails as well, and responded with some interesting thoughts re: quality. Shared with permission:

Aside from hard metrics that are often difficult to install, there’s also a lot of experience involved. I look into details like communication, discipline, timetables and overall presentation of the topic and the approach of the presenter. Does it “feel” right/good/viable or are they just putting on a good show? One major category is the quality & depth of their questions and documentation. If those offer good quality and are well structured, I usually find the rest of it also well produced.

Quality

Hi friend.

If you buy a piece of furniture, like a chair, you can compare it with all the other chairs in the exhibition. You can sit on them and compare how they feel. You get a feel for the wood, whether it‘s cheap or high quality.

How do you do that with code? Once the software is released you are able to compare and evaluate. But before?
