The introduction to Reactive Programming you've been missing

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.

Basecamp was under network attack

The attack detailed below has stopped (for the time being) and almost all network access for almost all customers have been restored. We're keeping this post and the timeline intact for posterity. Unless the attack resumes, we'll post a complete postmortem within 48 hours (so before Wednesday, March 26 at 11:00am central time).

Criminals have laid siege to our networks using what's called a distributed denial-of-service attack (DDoS) starting at 8:46 central time, March 24 2014. The goal is to make Basecamp, and the rest of our services, unavailable by flooding the network with bogus requests, so nothing legitimate can come through. This attack was launched together with a blackmail attempt that sought to have us pay to avoid this assault.

Note that this attack targets the network link between our servers and the internet. All the data is safe and sound, but nobody is able to get to it as long as the attack is being successfully executed. This is like a bunch of people

How to setup your own CA with OpenSSL

For educational reasons I've decided to create my own CA. Here is what I learned.

First things first

Lets get some context first.

Sorry, RSA, I'm just not buying it

I want to be extremely clear about three things. First, this is my personal opinion – insert full standard disclaimer. Second, this is not a condemnation of everyone at RSA, present and past. I assume most of them are pretty okay, and that the problem is confined to a few specific points in the company. However, “unknown problem people making major decisions at RSA” is a bit unwieldy, so I will just say RSA. Third, I'm not calling for a total boycott on RSA. I work almost literally across the street from them and I don’t want to get beat up by roving gangs of cryptographers at the local Chipotle.

RSA's denial published last night is utter codswallop that denies pretty much everything in the world except the actual allegations put forth by Reuters and hinted at for months by [other sources](http://li

B-cycle Widget

B-cycle is a bike sharing service that operates in several American cities. More information at their website. This widget allows you to use the station ID in a widget to get the current count of bikes and docks available to show on your Dashing dashboard.

Demo

A demo repository is available on GitHub and here is a live Dashboard on Heroku.
