<>Welcome to the Theoi Project, a site exploring Greek mythology and the gods in classical literature and art. The aim of the project is to provide a comprehensive, free reference guide to the gods (theoi), spirits (daimones), fabulous creatures (theres) and heroes of ancient Greek mythology and religion. <<<<

<> A Programmer's Introduction to Mathematics uses your familiarity with ideas from programming and software to teach mathematics.

You'll learn about the central objects and theorems of mathematics, covering graphs, calculus, linear algebra, eigenvalues, optimization, and more. You'll also be immersed in the often unspoken cultural attitudes of mathematics, learning both how to read and write proofs while understanding why mathematics is the way it is. Between each technical chapter is an essay describing a different aspect of mathematical culture, and discussions of the insights and meta-insights that constitute mathematical intuition.

As you learn, we'll use new mathematical ideas to create wondrous programs, from cryptographic schemes to neural networks to hyperbolic tessellations. Each chapter also contains a set of exercises that have you actively explore …

Git is hard: screwing up is easy, and figuring out how to fix your mistakes is fucking impossible. Git documentation has this chicken and egg problem where you can't search for how to get yourself out of a mess, unless you already know the name of the thing you need to know about in order to fix your problem.

The study found that patients with Covid-19 treated in hospital who “received ivermectin early reported substantial recovery” and that there was “a substantial improvement and reduction in mortality rate in ivermectin treated groups” by 90%.

But the drug’s promise as a treatment for the virus is in serious doubt after the Elgazzar study was pulled from the Research Square website on Thursday “due to ethical concerns”. Research Square did not outline what those concerns were.

A medical student in London, Jack Lawrence, was among the first to identify serious concerns about the paper, leading to the retraction. He first became aware of the Elgazzar preprint when it was assigned to him by one of his lecturers for an assignment that formed part of his master’s degree …

Here we present a tool — the REAPPRAISED checklist — that aims to help readers, journal editors and anyone else assess whether a paper has flaws that call its integrity into question.

croc is a tool that allows any two computers to simply and securely transfer files and folders. AFAIK, croc is the only CLI file-transfer tool that does all of the following:

allows any two computers to transfer data (using a relay)
provides end-to-end encryption (using PAKE)
enables easy cross-platform transfers (Windows, Linux, Mac)
allows multiple file transfers
allows resuming transfers that are interrupted
local server or port-forwarding not needed
ipv6-first with ipv4 fallback
can use proxy, like tor

How to install Jupyter Notebook on Ubuntu 20.04 to share live code with others. In this guide, we’ll show you how to Install Jupyter Notebook on Ubuntu 20.04 LTS. Here we show you simple ways to install Jupyter on Ubuntu 20.04 LTS (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04 and any other Debian based distribution like Linux Mint and Elementary OS.

The psychology section is far and away the most substantive of the three fields, with an emphasis on Psychodynamics, Neuropsychoanalysis, Rogerian/person-centered approaches, and Social Psychology.

The Neuroscience section has a modest amount of anatomy, and leans towards perception, affective neuroscience, and other such frivolity.

The philosophy section is a basic overview with a slight bent towards cognition, and is perfect for winning internet arguments (or whatever it is that philosophy is supposed to be for)

In this video, Lisa and Heather go through the steps of creating a GitHub repository, cloning the repo using RStudio, adding a collaborator, making changes to the file collaboratively, and even a little bit of Git in the terminal. It is meant to help people using Git and GitHub with RStudio who already have GitHub set up.

List comprehensions were added with Python 2.0. Essentially, it is Python's way of implementing a well-known notation for sets as used by mathematicians. In mathematics the square numbers of the natural numbers are, for example, created by { x2 | x ∈ ℕ } or the set of complex integers { (x,y) | x ∈ ℤ ∧ y ∈ ℤ }.

List comprehension is an elegant way to define and create lists in Python. These lists have often the qualities of sets, but are not necessarily sets.

List comprehension is a complete substitute for the lambda function as well as the functions map(), filter() and reduce(). For most people the syntax of list comprehension is easier to be grasped.

The lambda operator or lambda function is a way to create small anonymous functions, i.e. functions without a name. These functions are throw-away functions, i.e. they are just needed where they have been created. Lambda functions are mainly used in combination with the functions filter(), map() and reduce(). The lambda feature was added to Python due to the demand from Lisp programmers.

The general syntax of a lambda function is quite simple:

lambda argument_list: expression

Connected papers is a unique, visual tool to help researchers and applied scientists find and explore papers relevant to their field of work. In the graph, papers are arranged according to their similarity. That means that even papers that do not directly cite each other can be strongly connected and very closely positioned. Connected Papers is not a citation tree.
