Why Tarsnap doesn't use Glacier
On the surface, Tarsnap sounds like the perfect use case for Glacier. Out of every TB of data stored on Tarsnap, in any given month approximately 100 GB of data will be deleted, while only 33 GB of data will be downloaded; in other words, Tarsnap is very much a "write once, read maybe " storage system. Tarsnap's…

The Value of In-House Expertise
An alternate title for this post might be, "Twitter has a kernel team!?". At this point, I've heard that surprised exclamation enough that I've lost count of the number times that's been said to me (I'd guess that it's more than ten but less than a hundred).
