Hope you enjoyed Commodity, and Cyberpunk as a Commodity before that, plus a number of personal blogs that thankfully are now presumed lost. Welcome back!
Welcome back for another book review. This time, I am going to review a book that I have bought when it came out, in late 2013. I have always wanted to do a review of this one but it seems I had two options: Write a short review that probably does not do the book… Continue reading Book Review: Systems Performance: Enterprise and the cloud
“Kept you waiting, huh?” – to start the post with a pop culture reference. Yesterday, I was privileged enough to attend Distributed Matters Berlin 2015. The focus of the conference is, you guessed it, distributed systems, often within a NoSQL context. It was hosted at the awesome KulturBrauerei, a refurbished brewery.

For my kickoff of systems engineering book reviews I have chosen this book. While not being technical in the strict sense of the term (if you are looking for code snippets or ready-to-use architecture ideas, look elsewhere), this collection of 17 essays provides a birds-eye view of the relatively new principle of Web Operations. As… Continue reading Book Review: Web Operations: Keeping the Data on Time

Well, here is some insight: professionally I have somewhat moved away from security to towards a systems engineering paradigm. While security still plays an… Continue reading Coming up on Commodity

A lot of the data sanitisation literature around advises overwriting partitions with random data (btw, SANS Institute research claims that even a pass with /dev/zero is enough to stop MFM but YPMV). So leaving Guttman-like techniques aside,… Continue reading P For Paranoia OR a quick way of overwriting a partition with random-like data
