Technically speaking, I had a fun and productive 2013. Here are some highlights worth mentioning.
StorageClient: Client Side Load Balancing
A technology specific problem solved, bypassing server based solution with client side load balancing and fast fail retry algorithms that took us from horrible to nearly 5 nines in reliability while improving overall performance. (This was at the day job, so that's about as much as I can share about that.)
LocalCache: In Memory Cache with Async Persistence
A library that takes advantage of Concurrent Collections in .NET and SQLite to provide fast in-memory caching that persists asynchronously on local disk for rapid rehydration of in-memory cache when an application pool is recycled. This solved a big problem with service level compliance recovery on a critical service, taking complete recovery time from hours to a few minutes. (Also for the day job.)
DuoVia.Net: TCP and NamedPipes Services Library
An extension and revival of RemotingLite that makes intra-process communication easy and fast. This was my first foray into creating and sharing open source software on GitHub and publishing packages on NuGet. I enjoyed it so much, I added 8 more packages to the set. And while these projects were built on my own time, one or two of them are in regular use by one or two teams at the current day job and they have been downloaded over 1,500 times.
VersionedCollections: A Shared Idea Brought to Life
Recently I shared an idea with Ayende Rahien on his blog with respect to creating a snapshot-in-time, read-only view of a collection that is being written to constantly. I'm happy to report that it turned out to be exactly what he needed. And I am honored and appreciative to Ayende for the kudos. Sharing good ideas with community friends is almost as much fun as bringing them to life yourself.
Here's to an equally fun and productive 2014.
