Archive for the ‘Agile’ Category – Meaningless Metrics, Treacherous Targets

Posted by jpluimers on 2022/12/15

Food for thought:

[Wayback] – Meaningless Metrics, Treacherous Targets

A common feature of organizations in the software technology industry (but certainly not only in that industry) is their fixation on metrics, measurements, and quantifiers. I understand that this is frequently done and advocated for in the spirit of making management more objective, less arbitrary, more scientific, and perhaps fairer. But since they say that the road to hell is often paved with good intentions, here’s a quick summary of what we know about about the undesirable side effects of such an approach.

Basically, when the metric becomes the goal, it will not reliably measure the underlying figures any more.

By [Archive] Florian Haas on Twitter: “I wrote something long-ish on metrics over the weekend. I’m pretty certain this won’t go unchallenged, as people tend to have strong opinions on this. 🙂 “.

Via [Archive] Kristian Köhntopp on Twitter: “In writing this, @xahteiwi had probably done more for the advancement of SRE as a practice than one hundred conference talks could do. Thanks for that.… “.

In life, including working life “slow is smooth, and smooth is fast.”

Posted by jpluimers on 2022/01/26

I’ve been agile all my (not just programming) life, and only figured out this century that there is a vocabulary for that, containing the words agile, extreme programming, feature-driven and many more.

Now with the passing of the years, I also realise I have been trying to do “slow and smooth” all my life, and that with age (and less adrenaline) this becomes easier and easier.

I think “slow and smooth” goes well with “agile”, specially when you keep the focus on “doing things right” (and trying to do them right the first time, and keeping it right in incremental steps).

It often reminds me of the Dutch phrase “heeft u haast, gaat dan zitten” which often is attributed to be part of the many Chinese proverbs. It roughly translates to “when in a hurry, take a seat”, and suggests to take a step back and think when under pressure. Maybe this English version of a Chinese proverb comes close: “When you are in a hurry, the horse holds back”.

For is it is intriguing that mainly Chinese, but in a broader sense Asian, proverbs play such an important role, whereas Western proverbs get less and less important. Informal knowledge seems to diminish in Western culture, which I think is a pity.

Maybe all these vocabulary things that started  to make sense way after my puberty also have to do with being diagnosed autistic at 50. That too started a lot of puzzle-pieces to suddenly make sense.

Below the links that inspired me to make this blog post in the first place:

Posted by jpluimers on 2021/12/29

Not just for during the Covid times: the helpful examples and thorough explanation by Florian makes this a must-watch video for anyone wanting to participate in distributed teams.

[Wayback] – No, we won’t have a video call for that!

The above link has downloads for both Video (mp4 and WebM formats) and audio (mp3 and opus formats). I found the video easier to digest.

If you want to watch it on-line, there is the YouTube video (below the signature) which has closed captions as well.

Kristian Köhntopp made a [Wayback/] short intro and abstract on Twitter:

Exactly one year ago, the office building I was working from every work day caught fire, and was closed for a month for renovation.

On the day of the planned reopening, my employer declared Covid emergency and asked everybody to work from home.

So that is how we work since then, and we will continue to do so until at least October.

Not too much has changed, though. When the new opens, there will be probably a lot of pain between the people who go to the office to work and those who don’t.

The talk above by @xahteiwi explains in a nice way how to work properly remote first:

  • Writing over speaking.
  • Asynchronous over synchronous.
  • Structured communication over free form.

Some things require a free form video chat, but even then, set an agenda and write minutes.

Florian also explains when to use what, and what situations would require a synchronous wide-band channel, but most of them are exceptional, and most of the time you could execute better using structured, written, async mode comms.

Having said that, if you want his talk as a briefing, here is a Youtube:

First watch the video, then read the full speaker notes at [Wayback] No, We Won’t Have a Video Call for That! – “My talk from FrOSCon 2020, Cloud Edition.”

13 Tips for Writing Useful Unit Tests | by Nick Hodges | Better Programming

Posted by jpluimers on 2021/12/21

[Wayback/] 13 Tips for Writing Useful Unit Tests | by Nick Hodges | Better Programming (I made direct links to the topics in the below quote):

How you write your tests is as important as writing them

1. Test One Thing at a Time in Isolation
2. Follow the AAA Rule: Arrange, Act, Assert
3. Write Simple “Fastball-Down-the-Middle” Tests First
4. Test Across Boundaries
5. If You Can, Test the Entire Spectrum
6. If Possible, Cover Every Code Path
7. Write Tests That Reveal a Bug, Then Fix It
8. Make Each Test Independent
9. Name Your Tests Clearly and Don’t Be Afraid of Long Names
10. Test That Every Raised Exception Is Raised
11. Avoid the Use of Assert.IsTrue
12. Constantly Run Your Tests
13. Run Your Tests as Part of Every Automated Build

Via a private message: Agile Rhapsody – Bohemian Rhapsody Parody – Scrum Team Building – Agile … on @YouTube

Posted by jpluimers on 2021/10/26

About half a year ago, someone shard this with me [] Jeroen Wiert Pluimers on Twitter: “Via a private message: Agile Rhapsody – Bohemian Rhapsody Parody – Scrum Team Building – Agile …  via @YouTube”.

It is a great video about agile, the manifesto and scrum: spot on.
