Bitcoin (BTC) price falls after Tesla stops car purchases with crypto #blockchain

Tesla CEO Elon Musk tweeted that the electric vehicle maker would suspend car purchases using bitcoin, citing environmental concerns.

Learn Python the Right way #programming #learning #ebook #free

We think that people who want to learn to code using Python should

• Learn in a no-setup environment so they can focus on code.
• Learn computer science fundamentals.
• Practice by building real-world projects.

That's why we created two books.

Universal basic income to be tested in Wales #society #economy

A universal basic income scheme is to be trialled in Wales, meaning adults, regardless of their means, will receive a regular sum of money.

The idea is that this would cover the basic cost of living.

First Minister Mark Drakeford said the pilot would "see whether the promises that basic income holds out are genuinely delivered" in people's lives.

But the Conservatives said Wales should not become "a petri dish for failed left-wing policies".

Was cancer really less likely in a pre-industrial world? #history #health #longread

Pre-industrial Britain wasn’t exactly carcinogen free: People regularly consumed alcohol, were exposed to indoor pollutants spewed out by wood and coal fires, and faced the risk of cellular mutations as they aged. But the threat of cancer markedly increased when carcinogens such as tobacco (first introduced in Britain in the 16th century) and pollution caused by industrial activities (beginning in the 18th century) were introduced into everyday life.
