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.

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.

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:

It might sound like I’m late in the game, but remember that blog posts are usually scheduled like a year in advance.
So I found out a long time ago (I think it’s Matthijs ter Woord who attended me) about Visual Studio Code.
At the start [WayBack] it was more limited (from memory something like C#, TypeScript, Java Script languages and frameworks Node.js and ASP.NET 5) than my other development environments but now it’s much richer.
It’s based on the Electron framework which I kew from the Atom.io editor and Koush‘s framework Electron Chrome that wraps Chrome Apps in Electron so he ensured Vysor would live after Google will kill Chrome Apps.
Oh it’s free and runs multi-platform which I like a lot (and was one of the reasons to start using Atom.io): Mac OS X, Windows and Linux are supported.
So here are a few links to get started:
I got reminded a while back** that it is now supported by OmniPascal [WayBack] which I like because of my Turbo Pascal -> VAX/VMS -> csh -> Delphi -> AS/400 -> .NET background.
Like Visual Studio Code is updated often, the Omni Pascal blog [WayBack] shows regular updates and I like it a lot better than the Lazarus IDE (I’m not a visual RAD person: I’m a RAD code person) especially the refactorings.
So start playing with it. I will post more about my Visual Studio Code experience in due time.

Heroku is a platform as a service (PaaS) that enables developers to build, run, and operate applications entirely in the cloud.
Source: Cloud Application Platform | Heroku
via:
As mentioned in the first part, node.js was initially developed for the cloud. While there are enough paid hosting providers available, much nicer is of course to get it running for free! :). We will try to get our node.js server of part 2 up and running in the cloud…
Source: Server-side Node.js (part 3): Node.js in the cloud (free hosting!) – Smart Mobile Studio [WayBack]
Heroku is ideal for experimenting as their free plan allows for sleeping dyno instances that only get activated when there is a need for it (they sleep after 30 minutes of inactivity) and rain from the pool of 1000 free dyno hours per month.
See these links for more information
