‘a Nagios plugin to poll Graphite’. Necessary, since service metrics are the true source of service health information

paperplanes. The Virtues of Monitoring, Redux
A rather vague and touchy-feely “state of the union” post on monitoring. Good set of links at the end, though; I like the look of Sensu and Tasseo, but am still unconvinced about the value of Boundary’s offering

What happened to KHTML after Apple announced Safari
‘There was a huge amount of excitement at the announcement that Safari would be using KHTML. At that time, it was almost a given that the OSS rendering engine was Gecko. KHTML was KDE’s little engine that could. But nobody ever expected it to be picked up by other folks. One of the original parts of the KHTML-to-OS X port was KWQ (pronounced, “quack”) that abstracted out the KDE API portions that were used in KHTML. Folks were pretty ecstatic at first. It seemed very validating. But that changed quickly. As Zack’s post indicates, WebKit became a thing of unmergable code-drops. Even inside of the KDE community there became a split between the KHTML purists and the WebKit faction. They’d previously more or less all been KHTML developers, but post-WebKit there was something of a pragmatists vs. idealists split. Zack fell on the latter side of that (for understandable reasons: there was an existing community project, with its own set of values, and that was hijacked to a large extent by WebKit). A few years later WebKit transformed itself into a more or less valid open source project (see webkit.org), but that didn’t close the rift in the KDE community between the two, at that point rather divergent, rendering engines. There’s still some remaining melancholy that stems from that initial hope and what could have potentially been, but wasn’t.’

Dan McKinley :: Whom the Gods Would Destroy, They First Give Real-time Analytics
‘It’s important to divorce the concepts of operational metrics and product analytics. [..] Funny business with timeframes can coerce most A/B tests into statistical significance.’ ‘The truth is that there are very few product decisions that can be made in real time.’ HN discussion: http://news.ycombinator.com/item?id=5032588
