In a mass of large bubbles The froth, therefore, though lacking long-range symmetry, nevertheless has very definite rules as to its composition. It is pleasing in appearance because the eye senses this interplay between regularity and irregularity. Structure, Substructure, and Superstructure symmetry
We wonder which is real, he of the picture or he who talks? In the tea room the fear of repetition is a constant presence. The various objects for the decoration of a room should be so selected that no color or design shall be repeated. If you have a living flower, a painting of flowers is not allowable. If you are using a round kettle, the water pitcher should be angular. A cup with a black glaze should not be associated with a tea-caddy of black lacquer. In placing a vase or an incense burner on the tokonoma, care should be taken not to put it in the exact center, lest it divide the space into equal halves. The pillar of the tokonoma should be of a different kind of wood from the other pillars, in order to break any suggestion of monotony in the room. Here again the Japanese method of interior decoration differs from that of the Occident, where we see objects arrayed symmetrically on mantelpieces and elsewhere. In Western houses we are often confronted with what appears to us useless reiteration. We find it trying to talk to a man while his full-length portrait stares at us from behind his back. We wonder which is real, he of the picture or he who talks, and feel a curious conviction that one of them must be fraud. Okakura Kakuzō, The Book of Tea repetitionsymmetry
Deadlines are bullshit An Article contrariantruth.substack.com In software development deadlines are a necessary evil.

External vs. internal deadlines When are deadlines necessary? Contractual obligations Technical liabilities (e.g., dependency EOL) Compliance, government, investors, and other external stakeholders What do all of these deadlines have in common? They are all important. They are all deadlines that cannot be missed. They are all external. When are deadlines evil? Your manager says you have a deadline Your software development methodology says you have deadlines What do all of these deadlines have in common? None of them are important. They are arbitrary. They are all internal. They are all bullshit.
Why are internal deadlines evil? Estimation: When estimating engineering work a substantial time investment is required by an engineer in order to get an accurate estimate. Misaligned Incentives: There is an incentive to lie and give estimates much longer than the feature is truly expected to take. Low Morale: Deadlines are likely to be missed often. Repeated failure has a cost to the morale of the team. Micromanagement: Deadlines are wielded by middle managers as a whip to harass and annoy engineers working on features. High Stress: When engineers feel the pressure of other stakeholders holding deadlines over their heads it creates an environment of high stress. High Turnover: On teams with high turnover rates the best engineers have an easy time finding new work and leave quickly, the worst engineers have a difficult time finding work and remain. This selects for a lower quality team over time.
Engineers who love their work The resolution is simple. Never have internal deadlines. Operate on a prioritized and ordered list of features. Estimate only when necessary to prioritize and do so in a t-shirt sizing way. Trust your engineers and they will begin to love their work. Engineers who love their work are happy and productive. Building is never a straight line
