Bosun is a monitoring and alerting system developed by the good folks at Stack Exchange, then open sourced for the rest of us. It’s written in Go, meaning its monitoring agents can run anywhere that Go can drop a binary… which is just about everywhere. So what exactly does it do and how does it compare to the likes of New Relic, CloudWatch, Nagios, Splunk Cloud, Server Density, and other monitoring tools?

Caching data is an essential part in many high-load scenarios. A local 1st-level cache can augment a shared 2nd-level cache like Redis and Memcached to further boost performance. An in-process cache involves no network overhead, so the cache speed is only limited by local resources like CPU, memory transfer speed and locking.

The future of web application development looks a bit different than what we are all used to. I'll show you how to build a simple full-stack JavaScript app using Node.js on the backend, React on the frontend, Webpack for client-side module support, and Netflix's Falcor as an efficient and intuitive alternative to the traditional REST API.

I like to think I’m pretty environmentally friendly. I try to minimize my waste , take quick showers, and not run unnecessary appliances, like heating and cooling systems. I’m definitely not a super earthy-crunchy-Hippie-type, but I’m at least vaguely cognizant of the atrocities I commit against Mother Nature. My main sin against the planet, aside from just being American, is the fact that I run errands in an 11,500 pound tank that gets 8 ..

Indirection is an extremely common programming technique. In fact, it's well known that all problems in computer science can be solved with an extra layer of indirection . Accessing data through a layer of indirection has some performance impact. The most important aspect of the performance impact however, is if the indirection is predictable . If the ultimately accessed data is accessed in a coherent order, even through a layer of in....

It took a while (1.5 years since my last class – I’ve been busy!), but I am ready with my Advanced Oracle Troubleshooting training (version 2.5) that has plenty of updates, including some more modern DB kernel tracing & ASH stuff and of course Oracle 12c topics! The online training will take place on 16-20 November & **14-18 December 2015 **(Part 1 and Part 2). The latest TOC is below: /files/AOT25_description.pdf Seminar regi..

there has been some movement in the last year or two to introduce some form of strong typing, or type hints, into Python. What does this mean, and how does it work? One way to think about it is by looking […]

Last weekend, the Python Hackathon Düsseldorf took place at trivago's office. Although we were only five people we had a lot of fun. I took the chance to brush up my Python skills a little bit. Also I wanted to scratch an itch that was bugging me for a long time: our housekeeping book.
