Awesome Falsehood Awesome Build Status

A curated list of awesome falsehoods programmers believe in.

The logic of the world is prior to all truth and falsehood.

  • Ludwig Wittgenstein



Falsehood articles are a form of commentary on a particular subject, and are appreciated by the developer community at large for their effectiveness and terseness. They're a convenient written form to approach an unfamiliar domain by dispelling myths, point out common pitfalls, show inconsistencies and subtleties.

In a sense, Falsehood articles are a suite of wordy unit-tests covering extensive edge-cases provided by real-world usage.

Good Candidates

Here is a non-restrictive list of items which are good candidates for inclusion in this awesome list.

Falsehood Articles

Articles following the falsehood scheme are prime candidates for inclusion in this awesome list.

These articles starts with the hypothesis that developers have a naive, simple view of the subject at hand. Then proceed to list a set of candid assumptions that might be held by such programmers. Each one is intentionally false, and sometimes illustrated by a counter-example.

A list of falsehood is crafted as a progression that is designed to refine concepts. Having read the whole list of falsehood, the reader should possess a global, if not complete, overview of the domain being targeted by the article, including most, if not all, its pitfalls, edges-cases and inconsistencies.

In the worst case, these articles might provoke an emotional reaction and cause flipping table. (╯°□°)╯︵ ┻━┻

Articles featuring items that are applicable to a product and a product only can't really be considered as generic falsehood articles and should be avoided.


When possible, we provide a list of programming libraries or modules that may solve, or try to, the complexities and idiosyncrasies pointed by the falsehood articles above.

So we can put back tables in place. ┬─┬ ノ( ゜-゜ノ)

Data Structures

Data models and structures generic enough to cover and address most of the falsehoods are also welcome in this page.
