Interesting read, especially about the node event-loop which tries to mask it is single threaded by doing cooperative multi-tasking: [WayBack] The Way of the Gopher – Digg Data – Medium – Making the Switch from Node.js to Golang.
It mentions [WayBack] GitHub – gengo/goship: A simple tool for deploying code to servers.

Wow, impressive work, and a very good explanation of some of the optimizations that take place and how you can check which ones work on your code: [WayBack] Why the New V8 is so Damn Fast – NodeSource:
The entire V8 compiler pipeline was overhauled and shipped with Node.js version 8. This post investigates what speed improvements we can expect as a result.

This looks like ndp is a drop in wrapper for node allowing for in depth debugging: [WayBack] GitHub – GoogleChromeLabs/ndb: ndb is an improved debugging experience for Node.js, enabled by Chrome DevTools

Sometimes your Atom installation gets so unstable that the quickest solution is a reinstall. For that you need to get a list of user-installed packages, then re-install them.
On Windows your Atom Package Manager apm is here (but not in the path), where the first is version specific and the latter the most recent version:
%LOCALAPPDAT%\atom\app-1.18.0\resources\cli\apm.cmd
%LOCALAPPDATA%\atom\bin\apm.cmd
On Mac OS X, it is here and in the path:
/usr/local/bin/apm
/Applications/Atom.app/Contents/Resources/app/apm/node_modules/.bin/apm
Save your packages:
apm list --installed --bare > package-list.txt
Install packages:
apm install --packages-file package-list.txt
For my own memory, the settings folders:
%USERPROFILE%\.atom~/.atom–jeroen

via: [WayBack] Hacker News – coinmon: In case you don’t want to install 61 packages [1] :) and [WayBack] The curl + jq based approach to check Bitcoin prices looks a bit more attractive than using a node.js package with 61 dependencies, doesn’t it? Source:… – ThisIsWhyICode – Google+
Function to call curl from bash:
$ coinmon() { > curl "https://api.coinmarketcap.com/v1/ticker/?convert=$1" | jq ".[0] .price_$1" > } $ coinmon eur "6988.4723188"
Or in Python (from the same HackerNew thread): [Archive.is] https://www.pastery.net/jnscrh/
#!/usr/bin/env python3 from urllib.request import urlopen from decimal import Decimal import json def print_coin(coin): print("{} ticker:".format(coin["name"])) print("Price: {:,} EUR".format(Decimal(coin["price_eur"]))) print("Market cap: {:,} EUR".format(Decimal(coin["market_cap_eur"]))) print() r = urlopen("https://api.coinmarketcap.com/v1/ticker/?convert=eur") coins = json.loads(r.read().decode("utf8")) for coin in coins: if coin["id"] in ("bitcoin", "ethereum", "ripple", "monero"): print_coin(coin)
