Diacritics

Marks added to letters, to denote sound changes, are referred to as diacritics.

Natural Law

Natural law is the idea that there exists moral laws, discernible by reason, inherent in the nature of humans and the world.  Many arguments for natural law depend on a belief in the existence of God.  Examples of widely accepted moral laws include the Golden Rule as well as prohibitions against murder, theft and lying.

SQL N + 1 Query Problem

One complex SQL query is typically faster than an equivalent set of simple SQL queries.  Extracting table rows in one query, and processing each row in additional queries, is slow.  It is typically faster to instead do one equivalent complex query.  This is referred to as the SQL N + 1 query problem. 

SQL Anti-Joins

SQL anti-joins return the rows of left and right joins with certain null columns.

Consonants & Vowels

Consonants, unlike vowels, involve airflow obstruction.

Hooks

Hooks are methods of customizing software applications.  Hooks "hook" on custom code.  Examples include Git and database event hooks.

Function Invocation Stacks

Computer function invocations typically utilize stack data structures and add frames to them. Frames typically include register values, function arguments, and, function internal variable values.

Voxels

Voxels are three dimensional analogs of pixels.

Python Types & Classes

In Python, types and classes are the same thing.  Both inherit from the object class.

Measurement Problem

Quantum mechanics does not precisely define what causes the Schrödinger wave function to collapse because it does not precisely define what a measurement is.  This is referred to as the measurement problem.

Centroids

 Centroids are vector averages.

YAML

YAML (YAML Ain't Markup Language) is a superset of JSON (JavaScript Object Notation) supporting the encoding of data structures using significant whitespace, and, the encoding of strings without using quotes.  For these and other reasons, YAML can typically encode key value pairs in a more user friendly format than JSON.

Agile Product Development Work Categories

Agile product development typically divides work into the following categories:

Research tasks are sometimes also referred to as spikes.

Unicode Symbols, Code Points & Encodings

Unicode associates symbols with integer code points. Code points have multiple possibile encodings.

Baryons & Mesons

Baryons are quark triplet hadrons like protons and neutrons. Mesons are quark antiquark pair hadrons like pions and kaons. Baryons are fermions and mesons are bosons.

Hadrons, Leptons & Gauge Bosons

Hadrons are quark sets like protons and neutrons. Leptons are "quarkless" half spin fermions like electrons and neutrinos. Gauge bosons are spin one bosons like photons, W particles, Z particles and gluons.

Fermions & Bosons

Fermions are fractional spin particles like electrons, protons, neutrons, quarks and neutrinos. Bosons are integer spin particles like photons, W particles, Z particles and gluons. Bosons are force carriers.

CRUD Interfaces

Database user interfaces for reading, writing (creation and updating) and deletion are referred to as CRUD interfaces.

Positivism

Positivism is the belief that knowledge comes only from measurements and reasoning about measurements. Positivists ignore what cannot be measured. Positivism was helpful in the development of general relativity and quantum mechanics.

Data Lakes, Data Warehouses & Data Lakehouses

Data lakes are unstructured data optimized data stores. Data warehouses are structured data optimized data stores. Data lakehouses are structured and unstructured data optimized data stores. Data warehouses may allow unstructured data but they are not optimized for it.
