An Essay by Baldur BjarnasonIs it the notetaking system that’s helping you think more clearly? Or is it the act of writing that forces you to clarify your thoughts?
Is it the complex interlinked web of notes that helps you get new ideas? Or is it all the reading you’re doing to fill that notetaking app bucket?
Is all of this notetaking work making you smarter? Or is it just indirectly forcing you into deliberate, goalless practice?

A Website by Gwern BranwenThe goal of these pages is not to be a model of concision, maximizing entertainment value per word, or to preach to a choir by elegantly repeating a conclusion. Rather, I am attempting to explain things to my future self, who is intelligent and interested, but has forgotten. What I am doing is explaining why I decided what I did to myself and noting down everything I found interesting about it for future reference. I hope my other readers, whomever they may be, might find the topic as interesting as I found it, and the essay useful or at least entertaining–but the intended audience is my future self.

A Website by Andy MatuschakOn Memory Palaces & Visual Computation
An Essay by Taulant SulkoI now use Are.na as a Memory Palace, separating my channels into rooms. For example, I have a channel that I call the Computation Room. It’s pretty generic and includes any type of block that relates to computation.
If I notice a pattern in the computation room I create a more specific channel in that room. I think of that more specific topic as an object within the room.
Then there are the adjacent topics that I often find even more exciting to focus on. For those, I choose a name that corresponds with the nature of a room and also its size. For example I have a channel called the Visual Computing Observatory. In my head I am imagining an actual observatory where I am looking and observing and studying a given topic.
That the mind may not be taxed
A Quote by Thomas FarnabyIn order that the mind may not be taxed, moreover, by the manifold and confused reading of so many such things, and in order to prevent the escape of something valuable that we have read, heard, or discovered through the process of thinking itself, it will be found very useful to entrust to notebooks...those things which seem noteworthy and striking.
What's Wrong With This Model?
What's wrong with the rational model
- We Don’t Really Know the Goal When We Start
- We Usually Don’t Know the Decision Tree – We Discover It as We Go
- The Nodes Are Really Not Design Decisions, but Tentative Complete Designs
- The Goodness Function Cannot be Evaluated Incrementally
- The Desiderata and Their Weightings Keep Changing
- The Constraints Keep Changing
Deciding what to design
We Don’t Really Know the Goal When We Start
The most serious model shortcoming is that the designer often has a vague, incompletely specified goal, or primary objective. In such cases, the hardest part of design is deciding what to design.
I came to realize that the most useful service I was performing for my client was helping him decide what he really wanted.
Today, we recognize that rapid prototyping is an essential tool for formulating precise requirements. Not only is the design process iterative; the design-goal-setting process is itself iterative. Knowing complete product requirements up front is a quite rare exception, not the norm. Therefore, goal iteration must be considered an inherent part of the design process.
Evaluating goodness
The Goodness Function Cannot be Evaluated Incrementally
The Rational Model assumes that design involves a search of the decision tree, and that at every node, one can evaluate the goodness function of several downward branches. In fact, one cannot in general do this without exploring all the downward branches to all their leaves, which is possible in principle, but leads to a combinatorial explosion of alternatives in practice.
Changing constraints
The Constraints Keep Changing
The explicit listing of known constraints in the design program helps here. The designer can periodically scan the list, asking, “Can this constraint now be removed because the world has changed? Can it be entirely circumvented by working outside the design space?”
They just don't work that way
Perhaps the most devastating critique of the Rational Model, although perhaps the hardest to prove, is that most experienced designers just don’t work that way.
“Conventional wisdom about problem-solving seems often to be contradicted by the behavior of expert designers. Empirical studies of design activity have frequently found ‘intuitive’ features of design ability to be the most effective and relevant to the intrinsic nature of design. Some aspects of design theory, however, have tried to develop counter-intuitive models and prescriptions for design behavior.” — Nigel Cross
We must outgrow it
Why all this fuss about the process model? Does the model we and others use to think about our design process really affect our designing itself? I believe it does. I believe our inadequate model and following it slavishly lead to fat, cumbersome, over-features products and also to schedule, budget, and performance disasters.
The Rational Model, in any of its forms, leads us to demand up-front statements of design requirements. It leads us to believe that such can be formulated. It leads us to make contracts with one another on the basis of enshrined ignorance. A more realistic process model would make design work more efficient, obviating many arguments with clients and much rework.
The Waterfall Model is wrong and harmful; we must outgrow it.
