Bitcoin transactions could consume as much energy as Denmark by the year 2020

hqdefault (1)

The numbers in this study are very back-of-the-envelope and assume a worst case: widespread adoption of Bitcoin and not much improvement in Bitcoin mining activity, along with long replacement cycles for older, less efficient mining rigs.

Trumpscript: a programming language based on the rhetorical tactics of Donald Trump

056c026d-1c66-4d42-9fae-a8e96df290c5-1020x926

Trumpscript -- a python variant -- only allows numbers over 1,000,000; has no import statements (all declarations must be homegrown); only has integers because floating-point numbers are un-American (America never does anything halfway); only allows popular words and the names of politicians as variable names; limits error messages to direct Trump quotes; and requires that all programs end with "America is great."
