Switching over to daylight saving time, and losing one hour of sleep, raised the risk of having a heart attack the following Monday by 25 per cent, compared to other Mondays during the year, according to a new US study released today. […] The study found that heart attack risk fell 21 per cent later in the year, on the Tuesday after the clock was returned to standard time, and people got an extra hour’s sleep.One clear answer: we need 25-hour days.

Researchers used Michigan’s BMC2 database, which collects data from all non-federal hospitals across the state, to identify admissions for heart attacks requiring percutaneous coronary intervention from Jan. 1, 2010 through Sept. 15, 2013. A total of 42,060 hospital admissions occurring over 1,354 days were included in the analysis. Total daily admissions were adjusted for seasonal and weekday variation, as the rate of heart attacks peaks in the winter and is lowest in the summer and is also greater on Mondays and lower over the weekend. The hospitals included in this study admit an average of 32 patients having a heart attack on any given Monday. But on the Monday immediately after springing ahead there were on average an additional eight heart attacks. There was no difference in the total weekly number of percutaneous coronary interventions performed for either the fall or spring time changes compared to the weeks before and after the time change.

a reasonable workaround for Ruby’s GC problems in web apps
actually sounds quite nice
This is a couple of years old, but I like this:
Turbo Boyer-Moore is disappointing, its name doesn’t do it justice. In academia constant overhead doesn’t matter, but here we see that it matters a lot in practice. Turbo Boyer-Moore’s inner loop is so complex that we think we’re better off using the original Boyer-Moore.A good demo of how large values of O(n) can be slower than small values of O(mn).
in a field as critical and competitive as smartphones, Google’s R&D strategy was being dictated, not by the company’s board, or by its shareholders, but by a desire not to anger the CEO of a rival company.This is utterly bananas and anti-competitive. (via Des Traynor)
Interesting — Netty has imported an optimized ASL2-licensed MPSC queue implementation from Akka (presumably for performance raisins)
