Am I Even Qualified? (My Path to SRM)

I wasn’t the smartest kid in school. I was either bored and making better use of my time in class or frustrated by things I did not understand. Even if I ignore my devastating track record of attempts in mastering the Latin language I was a below average student in terms of grades. During most, but not all, school years I made it to the next level.

Magic Mail

After the DEFCON conference earlier this year in Las Vegas, I watched David Copperfield’s show at the MGM Grand. I wanted to see him for years (he’s kind of a childhood hero of mine), but never managed to squeeze it into my schedule. This time, however, my return flight was a day later than usual so I used the opportunity to finally see the legend with my own eyes. What a wonderful, impressive show that was! The illusions were astonishing! I had a close-to-front-row seat, and since Mr. Copperfield was performing large parts of the show from within the audience space, I felt like being in the middle of the magic.

Flash Cards for Site Reliability Engineers

When Site Reliability Engineers architect systems they often use a method called Non-Abstract Large System Design (NALSD). NALSD describes an iterative process for designing, assessing, and evaluating distributed systems. During the process it comes in handy to know some numbers about typical computing and data transferring tasks, such as locking a mutex or reading data from an SSD. Jeff Dean even went so far to declare that everyone should know at least the most important numbers:

IP over Web-avian Carriers

The Internet is notoriously hungry for bandwidth and much effort goes into increasing the throughput of Internet Protocol carrying media. One particularly successful approach in throughput optimization has been IP over Avian Carriers which, thanks to pleasant developments in storage media density, managed to stay ahead of the game by a factor of three. However, speeding up existing protocols is not enough to meet increased bandwidth demands. New protocols and unconventional link media have to be considered to keep the lights on and the bytes flowing.
