I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

As usual, use it at your own risk. I am not to be held responsible for your actions.

Supported devices: WNR1000v2 (tested by me), WNR1000v2-VC (provided by Comcast for free; tested by Douglas Fraser)

Notice: Upgrade WNR1000v2 to the latest factory firmware: 1.1.2.58. Otherwise, the power LED may not behave properly.

You need to place the device into failsafe mode. For booting into failsafe mode, you need to power up the device while holding the reset button with a pin. The power LED should have an amber colour. Hold the button until it is starting to flash green. It starts to flash green after it flashes the amber LED for six times. After that, the device is in failsafe mode, accepting a firmware via its TFTP server. The device should respond to pings at 192.168.1.1, although the responses may be malformed.

The introduction to Reactive Programming you've been missing

(by @andrestaltz)

So you're curious in learning this new thing called Reactive Programming, particularly its variant comprising of Rx, Bacon.js, RAC, and others.

Learning it is hard, even harder by the lack of good material. When I started, I tried looking for tutorials. I found only a handful of practical guides, but they just scratched the surface and never tackled the challenge of building the whole architecture around it. Library documentations often don't help when you're trying to understand some function. I mean, honestly, look at this:

Rx.Observable.prototype.flatMapLatest(selector, [thisArg])

Projects each element of an observable sequence into a new sequence of observable sequences by incorporating the element's index and then transforms an observable sequence of observable sequences into an observable sequence producing values only from the most recent observable sequence.
