Cloudy Data Storage, circa 2001

Published under Technology

Around 2000-2001, Oasis Digital built a system for a client which (in retrospect) took a “cloudy” approach to data storage. 2001 is a few years before that approach gained popularity, so it’s interesting to look back and see how our solution stacks up. The problem domain was the storage of check images for banks; the […]

Fix timestamps after a mass file transfer

Published under Technology

I recently transferred a few thousand files, totalling gigabytes, from one computer to another over a slowish internet connection. At the end of the transfer, I realized the process I used had lost all the original file timestamps. Rather, all the files on the destination machine had a create/modify date of when the transfer occurred. […]

(Here is a direct MP4 download, suitable for viewing across more platforms.) I had […]

I’m giving a talk (one of two) at the first meeting. Contrary to the initial description floating around, I won’t be speaking (in […]

Massive Parallelism and Microslices

Published under Business,Technology

I just read James Hamilton’s comments on “Microslice” servers, which are very low-power, but high CPU-to-wattage ratio servers. As he explains in detail, at scale the economics of this design are compelling. In some ways, of course, this is the opposite of another big trend going on, which is consolidation through virtualization. I reconcile these […]
