Exactly-once Support in Apache Kafka – Jay Kreps
If you’re one of the people who think [exactly-once support is impossible], I’d ask you to take an actual look at what we actually know to be possible and impossible, and what has been built in Kafka, and hopefully come to a more informed opinion. So let’s address this in two parts. First, is exactly-once a theoretical impossibility? Second, how does Kafka support it.

Smart TV hack embeds attack code into broadcast signal—no access required | Ars Technica
Awesome.
The proof-of-concept exploit uses a low-cost transmitter to embed malicious commands into a rogue [DVB-T] signal. That signal is then broadcast to nearby devices. It worked against two fully updated TV models made by Samsung. By exploiting two known security flaws in the Web browsers running in the background, the attack was able to gain highly privileged root access to the TVs. By revising the attack to target similar browser bugs found in other sets, the technique would likely work on a much wider range of TVs.

Serf
'a service discovery and orchestration tool that is decentralized, highly available, and fault tolerant. Serf runs on every major platform: Linux, Mac OS X, and Windows. It is extremely lightweight: it uses 5 to 10 MB of resident memory and primarily communicates using infrequent UDP messages [and an] efficient gossip protocol.'
