PKM in practice

What is cognitive load? “When the brain has to deal with multiple elements of information, difficult material, and you have to manipulate or process those different elements, working memory can struggle. It imposes a heavy working load on working memory – that is cognitive load … Intrinsic cognitive load is the load complex material places… Read more »

the end of control

Did print enable democracy, and is that why the founders of the USA put freedom of the press into their Constitution? “ … just invent the printing press. Wait a couple of hundred years while literacy spreads, and presto! We can all talk to one another again, after a fashion, and the democratic revolutions begin.” —Gwynne… Read more »

learning in the flow of work

Networked humans in a connected society: Our increasing inter-connectedness illuminates the need for cooperation. Simple work keeps getting automated, but still needs human oversight. Complicated work gets automated, outsourced, or contracted to the lowest cost of doing business. Complex work can provide a unique business advantage — but complex work is difficult to copy. Creative… Read more »

a mixed bag

Every fortnight I curate some of the observations and insights that were shared on social media. I call these Friday’s Finds. “Humanity’s problem today is that we have Paleolithic emotions, medieval institutions, and god-like technology.” —E. O. Wilson, via @Kpaxs @snowded — “In complexity … you define a direction of travel, not a goal, because if… Read more »

Some… Read more »

One of the few areas where most nations cooperate is in infectious disease control. For nation states, cooperation is the best option in this type of ‘prisoner’s dilemma‘. “On 31 December 2019, the World Health Organization was alerted about a cluster of pneumonia cases of unknown etiology in Wuhan, China, which prompted international concern of… Read more »

learning about machine learning

Why is machine learning [ML] important for your business? If you work at Nokia, your Chairman can explain it to you in a one hour presentation he developed over six months of research. Risto Siilasmaa helped make his network smarter. Everyone needs to know if ML can help with their business problems, but first they… Read more »


If you find that people on social media have a tendency toward anger and outrage there is one action we all can take to diffuse the situation. It’s simple, but first we have to stop and think. If there is but one practice that will help make social media more civil, it is to always… Read more »

when trust is lost

When trust is lost, knowledge fails to flow. When knowledge flow is stemmed, trust is lost. There is widespread outcry in China over the death of Doctor Li Wenliang who identified the novel corona virus, was reprimanded by the police for discussing it in public, and then died from the virus. “For many people in… Read more »

skepticism and complexity

Every fortnight I curate some of the observations and insights that were shared on social media. I call these Friday’s Finds. “Skepticism: the mark and even the pose of the educated mind.” —John Dewey “A developed country is not a place where the poor have cars. It’s where the rich use public transportation.” —@EnriquePenalosa “We rarely… Read more »
