Xeito: Palabra en Gallego; hacer las cosas con xeito es hacer las cosas bien y con rigor y arte. Vamos, no hacer trapalladas. Sedme xeitosos siempre.

Talk is cheap. Show me the code — Linus Torvalds

Divide y venceras.

Enthusiasm matters! — Nat Friedman

The best approach when you apply “Clean Architecture” is to use common sense. (KISS)

There are only two hard things in Computer Science: cache invalidation and naming things. — Phil Karlton

Ask a programmer to review 10 lines of code, he'll find 10 issues. Ask him to do 500 lines and he'll say it looks good.

El código es como un chiste, si lo explicas es malo.

You can optimise for execution speed. You can optimise for space. But the most precious thing you should optimise for is understandability.

Any fool can write code that a computer can understand. Good programmers write code that humans can understand (Escribes una vez, lees src cuatro veces.) — Martin Follen.

There are only two kinds of languages, the ones people complain about, and the ones nobody uses — Bjarne Stroustrup

A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die. — Thomas Kuhn (1962)

Complexity is like a bug light for smart people. We can't resist it, even though we know it's bad for us.

There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies. — Tony Hoare

Technical debt is not created all at once. It's the accumulation of many small shortcuts over time. A few extra minutes early on could save hours or days of maintenance over time. — Eric Elliott

Junior programmers create simple solutions to simple problems. Senior programmers create complex solutions to complex problems. Great programmers find simple solutions to complex problems.  — Charles Connell

La comunidad te devuelve con creces los que les das.

Always leave the campground cleaner than you found it [Ser un buen boyscout, recoge la mierda de otros]. — Boy Scouts rule

A goal is a dream with a deadline. — Napoleon Hill

Work expands so as to fill the time available for its completion — Parkinson's law

Some people, when confronted with a problem, think “I know, I’ll use regular expressions.” Now they have two problems — Jamie Zawinski, on comp.lang.emacs [*]

python -m this — Guido van Rossum

Las empresas piensan: "!Ah, sois ágiles! Eso quiere decir que lo haceis rápido". Y no, no es eso. Ágil quiere decir que lo hacemos bien" — Pepe Doval

I) Put people before code, II) Make progress before you get consensus, III) Problems before solutions, IV) Contracts before internals — Pieter Hintjens

Community > Docs > Code — Fabien Potencier

A complex system that works is invariably found to have evolved from a simple system thot worked. A complex system designed from scratch never works and cannot be patched up to make it work. You have to start over with a simple system. — John Gall

Rewrites only work if the people involved in the 1.0 are also involved in the 2.0, and thus have the benefit of context + history and understand the accidental complexity in the old system. Otherwise, you end up with a second, different 1.0. — @kyleve

Cuando un sistema está en producción cuesta horrores sacarlo de ahí (preguntadle a los bancos) — @javisantana

Organizations which design systems (in the broad sense used here) are constrained to produce designs which are copies of the communication structures of these organizations — Conway's law

Cuando uno tiene un martillo todo le parecen clavos (otra version de Conway's law) — Manel

If debugging is the process of removing bugs, then programming must be the process of putting them in. — Edsger W. Dijkstra

If your software developers are able to accurately estimate how long something will take, you should fire them. If they've done something so many times before that they know exactly how long it'll take them to do it again, then they should have made a reusable solution by now.

First Law of Software Architecture: Everything in software architecture is a trade-off. — Fundametals of Software Architecture. Mark Richards and Neal Ford

Los programadores tenemos un problema, no sabemos construir sobre lo que los demás han construído ya. (Not invented here) — Javi Santana

Los programadores quieren programar. La vaca va al monte.

Ningún Plan, por bueno que sea, resiste su primer contacto con el enemigo. — Helmuth von Moltke

Prefiere la evolucion que la revolucion.
