When running a large real-time processing system, monitoring is critical. But it does more than allow you to keep an eye on your system. During development it allows you test hypotheses about how it works, how it performs when certain parameters are changed, and takes the guessing out of working with dynamic systems.
The Boost ASIO Library is a wonderful piece of software. I’ve built high-performance event-driven IO C++ programs that just scream — it works very well. However, there is one subtlety when it comes to timers — specifically when it comes to cancelling expired timers.
Cassandra is an open-source, distributed database, informally known as a NoSQL database. It is designed to store large amounts of data, offer high-write performance, and provide fault-tolerance. I recently needed some hands-on experience with Cassandra, and being relatively new to Java programming, needed a simple set-up with which I would experiment.
I finally moved to mutt for my Loggly e-mail (which runs on Google Mail). After moving from e-mail client to e-mail client, I was keen to give it a try — the minimalist design and speed really appealed.
It took a little while to get it just right, but it’s up and running now. I’m pretty happy with it so far, and might consider using it for my personal Yahoo! Mail.

After almost 5 years at Riverbed Technology, it’s time for new challenges. I’ve started a new development position at Loggly in San Francisco, helping to build their Cloud-based Logging-as-a-Service platform.
I spent significant time at building systems that needed comprehensive logging support. But it’s something that developers don’t need to worry about — let others do it for you.
Dogfood testing is an effective way to increase testing, and get valuable feedback, on one’s products. It can be especially effective in the earlier stages of a product’s development, when the user base can be small. Having a forgiving — and sometimes captive — audience provides very useful feedback.
My experience with Fedora 15 was not as I had hoped. The ATI graphics driver was particularly problematic (regular minute-long hangs due to spinlock issues) so I decided to try a completely different distribution. I decided to go with Kubuntu 11.04 and performance has been excellent.
