Mermaid Wardley Map Example Tea Shop

~ chriseyre2000 ~ Leave a comment

I am starting to experiment with the Mermaid Wardley Map

<html>
  <body>
    <pre class="mermaid">
      wardley-beta
      title Tea Shop
      size [1100, 800]
      
      anchor Business [0.95, 0.63]
      anchor Public [0.95, 0.78]
      component Cup of Tea [0.79, 0.61] label [19, -4]
      component Cup [0.73, 0.78]
      component Tea [0.63, 0.81]
      component Hot Water [0.52, 0.80]
      component Water [0.38, 0.82]
      component Kettle [0.43, 0.35] label [-57, 4]
      component Power [0.1, 0.7] label [-27, 20]
      
      Business -> Cup of Tea
      Public -> Cup of Tea
      Cup of Tea -> Cup
      Cup of Tea -> Tea
      Cup of Tea -> Hot Water
      Hot Water -> Water
      Hot Water -> Kettle
      Kettle -> Power
      
      evolve Kettle 0.62
      evolve Power 0.89
      
      note "Standardising power allows Kettles to evolve faster" [0.30, 0.49]
      note "Hot water is obvious and well known" [0.48, 0.80]
      note "A generic note appeared" [0.23, 0.33]
      
     </pre> 
    <script type="module">
      import mermaid from 'https://cdn.jsdelivr.net/npm/mermaid@11/dist/mermaid.esm.min.mjs';
      mermaid.initialize({ startOnLoad: true });
    </script>
  </body>
</html>

Not a bad start.

Minimal Wardley Map in Mermaid js

~ chriseyre2000 ~ Leave a comment

I have been following the wardley map addition to mermaid js

<html>
  <body>
    <pre class="mermaid">
      wardley-beta
      title Software Platform Strategy
      size [1100, 800]
      
      evolution Genesis@0.25 -> Custom@0.5 -> Product@0.75 -> Commodity@1.0
      
      anchor Customer [0.90, 0.95]
    
      component Something [0.5, 0.5]
      Customer -> Something
     </pre> 
    <script type="module">
      import mermaid from 'https://cdn.jsdelivr.net/npm/mermaid@11/dist/mermaid.esm.min.mjs';
      mermaid.initialize({ startOnLoad: true });
    </script>
  </body>
</html>

This is a terrible example of a wardley map, but does give a starting point for exploring.

I now need to wait for the github and notion components to be updated!

Currently github is on 11.13.0

Notion is on 11.10.0

The miro plugin is back on 10.x so getting rather old!

It was the year that they immanentized the Eschaton

This is a line from the start of the Illuminatus Trilogy. This was a series of satirical novels written in the 1970s. I read them in the late 80s/early 90s.

The phrase literally means actively bringing about the end of the world.

This is the first time that I have known of a war when key agents on both sides are trying to bring about the end of the world.

Pete Hegseth (Secretary of War) openly pushes end-times prophecy.

Shia theology also has strong end of days themes.

This combo makes the mutually assured destruction thinking from the cold war break down.

AI and Managing Outsourcing

~ chriseyre2000 ~ Leave a comment

There are claims that AI has solved writing code. This implies that we have recreated the outsourcing model.

The problem is that writing code is not the goal. We really want to solve problems and find using a computer to do the job is the most efficient way to do this. A large part of the value I bring is to understand how a system works. That way we can make changes that improve the existing system.

Some years ago a project was run at a company where I worked. The manager thought it was clever to hire a team of the cheapest developers he could find. The team was limited to 7 people since that was the power supply limit of the available room. The two permanent developers did their best to give instructions to this team. We had a suite of acceptance tests that was heading to being green as the critical launch day arrived. Two of the team had commit rights revoked due to repeatedly committing broken code.

Not being involved in the project I left the office at my usual end of day time. The next morning I arrived and found out about the chaos that had ensued.

2 of the 7 subsystems deployed to production were simply mocks. These were sufficient to get the test scripts to work.

The team QA had quit twice (the first time being talked down). The two in house devs had to implement minimal versions of the services. Mangement had introduced a no-one goes home til this works policy after I had left. The devs had been checked into a nearby hotel late that night!

In the end we had a shop that could not sell anything until halfway through the next day.

It took about a year to get the system into a sane state before we replaced it again.

Management had considered this a success. This was mostly due to us eliminating an Oracle DB that would have cost a fortune to renew.

This is what happens with a small team of developers. This is exactly what people are doing with AI. They are generating systems from incomplete specifications.

Why is my screenshare going slow?

~ chriseyre2000 ~ Leave a comment

I had fun this week with using google meet to share my desktop it became so slow that I could not communicate effectively. There seem to be two causes:

Google meet is less effective on Firefox than on Chrome. This could be by design. Moving from Firefox to Chrome for the sharing made a big improvement, but did not fix everything.

The second issue was found using top. I had a number of instances of rg that started to use 100% of the CPU. This coincident with VS Code starting searches that it did not finish.

In the end it came down to the small gear icon shown below. It needs to be in the “Use exclude settings and ignore file mode”
