(via Vlad) An instructive interview that shows how people make mental mistakes by extrapolating technology solutions with "more-of-the-same" thinking:
http://archive.is/6M8mg#selection-1375.7-1381.541

We spend our time looking for threats against a company. We look for things that might be active inside the company that would cause us concern, and then of course we look to respond—detecting, containing, and deflecting those threats as much as possible while at the same time keeping in mind that our executives and board of directors always want to know what's going on with security in the company.

Generically, every breach has the big data problem. For example, in a malware incident that results in a breach, the malware comes in and spreads across the environment.

When that scope [of investigation] expands, the security team typically has to deal with a sudden increase in big data -- logs, alerts, etc. -- making budget planning critical. Right now I'm planning my budget for next year, and I hope I ask for enough disk space and computing power so that the infrastructure is prepared for future attacks. ... Burst capacity is really critical for the security team who needs to find answers quickly.


Basically, she assumes that data security and hardware capacity/budget are "entangled" linear orders.

D and D-op are linear orders.


Production possibility frontiers

An opportunity cost will usually arise whenever an economic agent chooses between alternative ways of allocating scarce resources. The opportunity cost of such a decision is the value of the next best alternative use of scarce resources. Opportunity cost can be illustrated by using production possibility frontiers (PPFs) which provide a simple, yet powerful tool to illustrate the effects of making an economic choice.

A PPF shows all the possible combinations of two goods, or two options available at one point in time.

Production possibilities

Mythica, which is a hypothetical economy, produces only two goods - textbooks and computers. When it uses all of its resources, it can produce five million computers and fifty five million textbooks. In fact, it can produce all the following combinations of computers and books.

Влад был прав; с функторами все гораздо лучше получается.

Rationality works best, that is, we generally get the kind of results that we want, in a world where the choices are very limited. Now, the reason for that is very simple. When you structure the environment by rules, laws, and tools and techniques, the players are constrained in certain directions. It is the constraints on the actors that help the decision-maker. The more unconstrained the environment, through lack of an effective artifactual structure, the more difficult it is for people to make choices or to implement their choices in effective ways.

Сегодня порисовал вот такие диаграммы, и на душе как-то полегчало. Все-таки Universal Property очень ценная идея. Надо бы научиться ею правильно пользоваться.

...in fact modernity is a surprisingly simple deal. The entire contract can be summarised in a single phrase: humans agree to give up meaning in exchange for power.
