WebStorm vs VSCode

WebStorm vs VSCode

Tradeoffs

VSCode pros

  • Popular
  • MDX support
  • Can jump to files from console, e.g. when running eslint

VSCode cons

  • Cannot look at tab title and tell if file is new, modified, unstaged, or has errors
  • Cannot advance to next file in git view

Installing cpuminer-multi on macOS 10.13.2 (High Sierra)

Installing cpuminer-multi on macOS 10.13.2 (High Sierra)

This assumes you have brew installed and are comfortable using a terminal.

Following the guide on https://github.com/tpruvot/cpuminer-multi will likely lead to errors about invalid paths to OpenSSL, and neoscrypt errors to the tune of Undefined symbols for architecture x86_64 during the build. I managed to piece together different fixes into an installation that has worked for me. So I hope it works for you.

Requirements

Ensure a c compiler is installed. Type g++ in the terminal and continue with the xcode installation if necessary. If it prints clang: error: no input files, then you can proceed.
