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 needed some C++ code to generate Type-1 time-based UUIDs. The Boost libraries, while offering support for other types, don’t have support for time-based UUIDs.
A cut of my code can be found in github.
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.
Why not check out Loggly for your logging and monitoring needs? And if you like building scalable, distributed, software systems, why not join us?
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.
I just wrote a post for the Riverbed Blog about Dogfood testing during development of the Riverbed Cloud Portal. You can check it out here.

CPU emulation, particularly of older processors, is an interesting topic.
While emulation source code for various CPU cores is easily available, I wanted to better understand how to interface the emulated CPU with my host machine. Therefore I decided to write a simple example of a host system for an emulated MOS Technology 6502 microprocessor.
The goal would be to have the emulated 6502 write “Hello, world” to the console of my linux desktop machine.
It’s been almost 18 months since I installed Fedora Core 12, so I decided to move onto Fedora 15.
While the install went OK, I am not (yet) convinced it was worth the hassle. While it’s nice to pick up bug fixes, I haven’t noticed much change to the feature set.
