There are professional bettors who make money on horse racing (eg: Alan Woods). They look at historical odds of horses, jockeys, weather conditions, track conditions etc and like these 'predators' on DFS use models to predict probabilities of runners winning. When the estimated probability of the horse winning exceeds the estimated final public probability by the track take, they bet, and bet big. Lots of data, lots of modelling, algorithmic, lots of domain knowledge, and fully automated. No need to scrape websites, totes will supply the latest odds take their bets programmatically.

Do you consider betting on horse racing as gambling? To be honest, for the professionals placing bets in this way, I don't (keep in mind it's very very easy to incorrectly place yourself in this category, and you will lose). But the vast majority of people betting on DFS do not, and can not, take this approach. For them, horse racing and DFS are very much gambling.

We have some racks with public facing ILOM interfaces which sit outside the firewall, which turns out have ntpd running. We only noticed when our international bandwidth crawled to a halt due to them being used in an NTP attack.

It's a hassle, as they're old machines and out of support contract (so we can't upgrade the firmware), and so far as I can tell there's no way to turn off public access to ntpd over the admin interfaces. We're stuck with having to go to the hosting company and change the cabling to route them through the firewall.

Just because you didn't set up ntpd doesn't mean you don't have it running (somewhere).

One of my daily tasks is to ssh into a remote Windows server, port forward the RDP port, connect to the local forward using remote desktop, close any dialogs about crashed drivers, open a java application that displays a KVM terminal connected to a serial port, and through the KVM control two separate devices with a series of magic key-presses to log into two accounts at the start of each day.

I automated this with Sikuli (http://sikuli.org/); the ninja feeling while watching it run was awesome (now it runs before I come into the office).

Sikuli made the job perversely fun, and the entire script is less than 100 lines of python. Highly recommended for any sort of GUI automation (though watch the dependency on Java 1.6; 1.7 doesn't work).

Anki is a great spaced repetition tool; despite only using it for 20 minutes each day to remember the Japanese Kanji, it has resulted in me remembering a lot of characters (but English -> Kanji and vice versa).

If you're looking to memorise a lot of data, it's definitely worth a look (runs on Mac, Windows, and Linux).
