High Level Software Project Consoluting Service

From now on, I offer a high level Software project consulting service.

This means that I take a role outside of the in-the-trenches work of your project.
My contribution is to provide guidance and supervision, mostly at the meta level.
Being outside of the in-the-trenches work enables me to keep an overview and really see the whole thing.

E.g, I can help you with the following things:

  • Which people/experience/skills you need on your team
  • Helping you to become aware of the risks you are really taking when starting a software project. (and therefore hopefully you will assess whether you are really willing and capable to take that risk)
  • Helping you to find out whether a software project really solves the problem you are trying to solve with it.
  • Helping you to find out what you need to do before starting a software project even makes sense.
  • Helping you to explore options when a software project is off-track.
  • When involved on a regular basis: Help you to recognize the state and health of your software project.

In many cases my role will be to ask provocative questions that make you think about things you might not have been aware of before.

I am very confident that I can provide a valuable service, because:

  • I have 30+ years of experience in software development.
  • Experience with leading software projects. Both in my company and outside. With up to 10 people on the team.
  • Being directly involved in requirements engineering, and corrected the course of that when needed.
  • Extensive psychological knowledge and experience from 17+ years of psychotherapy and other activities.
  • Highly trained intuition when it comes to software projects. Including the human aspects of it.

My hourly rate for this service is US$ 200. (I may rise that fee later. So engage me while I am still at this level.)

We can do the consulting via Skype or on-site.
For on-site consulting you’ll also pay for travel cost and travel time.

All consulting has to be paid in advance.

More details provided on request. Just ask me.

New focus in my Business: Own products, High-level consulting, Physical Inventions

I have been preparing my business for a transition for some time now.

In short, I’ll focus and strengthen those areas of my business that work well and that are compatible with my mission and with my soul.
And I’ll phase out or stop the rest.

In details this means that I’ll focus more on the following:

  • I’ll focus more on my DemoRecorder-24×7 product. Which is a screen recorder for mission critical systems. This product is a long term committment. It is on the market since 20 years now. And I am determined to provide long term stability and maintenance for my clients.
  • I’ll create a high-level consulting service. Part of my mission is to help people to get answers to seemingly hard problems.
  • I’ll work on physical inventions. I already have written down many inventions. Now is the time to bring them to light and reap the harvest
  • I have another software product / business in the pipeline. But I keep this secret until the time is right to publicly announce this

This also means that I’ll reduce or stop the following activity:

  • I’ll stop the consumer version of DemoRecorder. It doesn’t make sense anymore to offer that. There are free software alternatives. And the market is so small that it does not make any economical sense to try to compete with these free software alternatives on a feature level.
  • I’ll stop writing software that I don’t own, i.e., I stop offering a software development service writing software for others. The writing is on the wall since about August this year that I should stop offering this service, even though I am very good at it.

    It doesn’t make sense economically anymore given all the other higher-level things going on in my business.

    And it also doesn’t make sense personally anymore. I am a creative person with a never ending stream of high quality ideas. It doesn’t make sense to implement other people’s ideas while I cannot keep up with getting my own ideas implemented. And my soul is sending me very intense signals that I should stop implementing other people’s ideas.

    Of course I’ll finish existing, active projects writing software for others. Emphasis on “active”.
    (I might even take small projects from time to time from customers that have treated me with respect, are calm and trustworthy and do not exert time pressure.)

    For customers who want to reactivate projects that they have suspended or stopped prematurely: I can offer my high-level consulting service to get you going with other developers, if needed.

Just returned from a trip to the US

I have just returned from a great business trip to the US.

In Chicago I have done several things to get a good and spiritually founded direction for my business.

I have done the following in Chicago:

  • a Sozo session with Margaret Nagib, which was an amazing experience.
  • have attended Perry Marshall’s “Memos from the head-office” seminar which was a great great great experience. It finally helped me to know what my mission is.
  • and more great things… (which I may or may not write about)

Chicagoland is a great place on earth.
It feels like what they call a “thin place”. Where you are more connected with God than in most other places.

People show that they love each other in all everyday transactions.
Great place, great people.

Then I went to another place in the US and visited a customer.
This is confidential, so I won’t write any more details about this here.

I’ll post more of the consequences of this trip.

I started Mentorship for OPW.

A while ago I have volunteered as a mentor of the OPW program.

The internship of my mentee, Asal Mirzaeva (Asalle ) has started a few days ago, and so has my mentorship. (Although we have already test-driven the mentor-mentee cooperation during Asalle’s qualification task.)

Her job is:

  • to replace manually written byteswapping code in the X-Server with code that is generated from the XCB protocol definitions,
  • and to add proper checks to the incoming protocol data, to fix some security problems.

Asalle is currently setting up the build and debug environment for building and debugging the X-Server. (Debugging the X-Server is quite tricky as you can imagine.)

Asalle is very talented and she already has a good understanding of how the protocol handling and byteswapping works in the X-Server, after reading the relevant source code.

Recording Human-Machine-Interaction: API-Recording vs ATG-Recording

The purpose of recording human-machine-interaction is that we can identify and fix causes of past problems so that these causes cannot happen anymore. These causes may either be on the human side or on the machine-side or in the combination of both.

In mission-critical systems you cannot afford to repeat (near-)accidents and (near-)disasters. Therefore you need to identify causes of such problems reliably the first time they happen. For that it is essential to use sufficient recording and logging that allows you to correctly reproduce all information required for such an analysis. Due to the importance of this, it is crucial to do this recording and logging correctly.

Recording human-machine-interaction is an essential component of a complete logging solution. Therefore it is important to do this correctly, too.

There are several methods for HMI-recording. (HMI is short for human-machine interaction.)

In this article I’ll pick two of them: API-recording and ATG-recording. These methods are both used in practice for recording human-computer-interaction. I’ll highlight the advantages and disadvantages of both methods, and provide a conclusion that may be surprising.

Entering the software project business on Dec 16th

[German translation below]

Starting with Dec 16th I will concentrate full time on my business.

This enables me to extend the scope of my business beyond my product DemoRecorder:

You may already send me project inquiries: I may however take longer for answering them because my time until Dec 16th is already reserved otherwise.

I can offer quite a bit for the software project outsourcing business:
