How to use strace for a daemon with multiple processes, including children

Years ago, I wrote about the various tools available for monitoring bandwidth usage for individual devices in a home network.

Moving from Rogers Internet to VMedia in Kitchener/Waterloo

This article describes why I decided to move off Rogers for the internet, what options are currently available in the local Kitchener/Waterloo area, and the details on how to switch from Rogers.

Rogers: Good and Bad

Rogers internet service is quite good from a functionality point of view. Their technical support is also acceptable, though sometimes you need to have more than one call to get an issue resolved.

Technical Debt Crisis

Some good points on the state of affairs in the web development world today ...

In the old days there was a respected profession of application programming. There was a minority of elite system programmers who built infrastructure and tools that empowered the majority of application programmers. Our goal was to allow regular people without extensive training to easily and quickly build useful software. This was the spirit of languages like COBOL, Visual Basic, and HyperCard. Elegant tools for a more civilized age. Before the dark times… before the web.

How to get Free HD TV using an Antenna in Waterloo, Ontario

Principles of Scientific Rational Thinking

Principles of scientific rational thinking:

Question Authority

No idea is true just because some authority says it is true. That includes you, and includes me.

Think for Yourself and Question Yourself

Don't believe something just because you want it to be true. Belief alone is not a criterion for truth.

Test ideas by evidence from observation and experiments

If a favorite idea fails a well designed test, it is not true. Get over it.

Follow the evidence wherever it leads

If something is proven wrong, then just accept that it is wrong.

And, if you have no evidence, just reserve judgement. You don't have to take a position for or against an idea.

You could be wrong

We are humans, and we may not have all the facts, so we are sometimes wrong. Accept that, and move to more observation and experimentation.
