Hidden Effects of Cheap Oil

Nowhere are the second-order consequences of cratering oil prices more varied, important, and unpredictable than in the Middle East. “ISIS is not as flush as it once was. It has cut spending on fuel and bread subsidies, while increasingly shaking down locals for cash. Fighters themselves may be feeling the squeeze, too.” The militant group’s revenue from selling oil had dropped to $300k per day, down from $2m a day in 2014. “I don’t think [the oil-revenue decline] will lead to [the Islamic State’s] collapse. … But it might accelerate their implosion”. Iran, meanwhile, has entered into negotiations with world powers over its nuclear program for a variety of reasons. But the fact that Iran is one of the world’s hardest-hit oil producers is surely one of them.

No Little Ice Age

Our results suggest that the existing consensus over a Little Ice Age in Europe is a statistical artifact, where the standard climatological practice of smoothing what turn out to be random data prior to analysis gives the spurious appearance of irregular oscillations. This is an example of the ‘Slutsky effect’ where filtering of purely random variations can produce spurious cycles

Fedex war stories

You mean the time FedEx towed one of its airplanes to the other side of a hanger to keep it out of sight of a sheriff with a lock and a chain sent to lock down the airplane as collateral for unpaid fuel bills?

You mean when some angry union people showed up objecting to FedEx pilots handling packages?

You mean the time 2 barrels of liquids in the shop got confused and maybe some bad stuff got pumped by mistake into the hydraulic systems of some unknown number of airplanes?

NTP reimplementation

Interesting account on the reimplementation of NTP (network time protocol, what is responsible for accurate time on all your devices)
2022-11-12: And now it’s time for PTP

Where NTP allows for precision within milliseconds, PTP allows for precision within nanoseconds. PTP has the potential to enable synchronization of GPUs across data centers, which could open up unprecedented scale in AI capabilities that is difficult to achieve today. This level of accuracy will help ensure synchronization of not only the computers on our networks today but also the advanced systems that will be on our networks in the future.
