Bill Duncan, in a blog on event-pair latency, Deep Dive, ETL Dotplots, showed a different way to look at a time series that includes latency or response times. When I'm doing load tests (and I did a lot last year) I normally take a pair of plots like these as my raw data. These are from… Continue reading A different dimension for time series plots
Not IBM's Multiple Virtual Storage, minimum version selection. In Russ Cox's article on minimum version selection, he addresses the problem of what to do with a conflict, when two dependencies of your program ask for two versions of a common dependency of theirs, one newer, one older. In his model, you can only have one, so one… Continue reading An alternative to MVS
Kunle Olukotun didn't like systems that wasted their time stalled on loads and branches. He and his team at Afara Websystems therefore designed a SPARC processor that did work without waits. It became the Sun T1. Speed without speculating The basic idea is to have more decoders than ALUs, so you can have lots of threads… Continue reading How to go fast without speculating… Maybe.

However, Colin McGregor just wandered past with the solution in his pocket. All too many devices are managed by… Continue reading An Internet of Only Good Things
In a previous life, I had to write a discipline of exceptions for the users of a library I had built for c++ games. In this incarnation, I'm working in Go, and need to do something of the same sort, so here's my pitch: Some errors are typos by the user. Others are things they've… Continue reading A Discipline of Errors
Contrary to our previous expectations, PIPEDA already guarantees a person the right to de-index material which is inaccurate, outdated or misleadingly incomplete, even if the publisher has a legally credible reason for not taking down the original document. We failed to see this because we all looked at the very public ongoing suits involving Google.… Continue reading De-indexing, unexpectedly solved
