I'm still reluctant to use TypeScript given that it has a serious type narrowing bug that is two years old! You'd think Microsoft could have sorted this out by now.

What the author refers to as "randomization strategies" is in fact regularisation: a set of techniques to prevent over fitting.

Yes.

This. Running a script which takes hours to execute, only to find you have a TypeError on the last line just before you get the results you need is really frustrating. Static typing is a must-have imo.

> I can probably write vanilla JS or Python code that does that in 10 lines or so and would finish in around 5 seconds.

Really? There are certainly frameworks that you can use to achieve this performance in that amount of code, but I would be really interested to see that in vanilla JS/Python.

Disclaimer: I worked for this company.

StarLeaf (https://www.starleaf.com/) is a great alternative for businesses.

It would be great if you could have simulation objects inherit from one another - e.g. if you're making a weather system to have a generic cloud, and then have thunder cloud and rain cloud inherit from cloud.

Light (read: any electromagnetic wave) cannot escape a black hole beyond the event horizon. Therefore this wouldn't work.

I have done a quick and rough translation of the German article into English. Hopefully this is better than the Google Translate version: https://gist.github.com/alexcoplan/0018e3320f99a612c737

This hangs and hogs the CPU on "Starting Docker VM" for me.

Same here

Do you need the semicolons?

Because it essentially acts like quick look for the terminal.

Umm.. Macs?

It makes pretty colours. http://alexcoplan.github.com/amazingjs/

These guys have worked well for me, and really cheap for a low-endish box: http://infiniserv.com

Very good explanation - thanks.

Once you get over the 3D header this article is amazing.. the visualisations are incredible.

And suddenly the true purpose of WebGL became clear..

This is pretty awesome, would be better if it was in sync with the music though? It gets out after a bit.

I would have thought that the kind of people who post on HN are going to be better at correct use of English than those on your average Facebook/Twitter stream.

Because Ruby isn't designed purely for making websites. You at least need to use Rack (or a similar API) to hook into a server.

PHP has a lot of features built in which make it almost comparable to a framework. This is because it is designed for making websites out of the box, Ruby is not.

There has to be some server involved - people can send broadcast messages and the fs maintains state between machines.

It looks like a JS console directly onto a server.

I'm guessing that that was probably a joke?

Can you interact with the dom inside opal?

I believe they use a timeout to handle infinite loops, but in 1.9.3 it doesn't actually loop anyway, you just get [[...]], and it throws an exception if you try to call a.collapse (or similar).

I'm guessing the problem would most likely be with their version of JRuby.

Have filed a bug report on their support system.
