Yammer Engineering – Resiliency at Yammer
Not content with adding Hystrix (circuit breakers, threadpooling, request time limiting, metrics, etc.) to their entire SOA stack, they’ve made it incredibly configurable by hooking in a web-based configuration UI, allowing dynamic on-the-fly reconfiguration by their ops guys of the circuit breakers and threadpools in production. Mad stuff

A network of ‘homes’, where children’s happiness was relentlessly destroyed
Stories of this sort will tumble out to the inquiry over the next 18 months, making it plain that the network of “homes” where children’s happiness had relentlessly, deliberately, systematically been destroyed, this archipelago of Catholic evil, had covered the entire island. These things should be kept in mind when next we hear it said that the social ills of today can be explained by reference to loss of faith in the traditional institutions of moral authority. This is the reverse of the truth and an insult to the victims of an unforgiveable sin.

Ukrainian police use cellphones to track protestors, court order shows
Protesters for weeks had suspected that the government was using location data from cellphones near the demonstration to pinpoint people for political profiling, and they received alarming confirmation when a court formally ordered a telephone company to hand over such data. […] Three cellphone companies — Kyivstar, MTS and Life — denied that they had provided the location data to the government or had sent the text messages. Kyivstar suggested that it was instead the work of a “pirate” cellphone tower set up in the area. In a ruling made public on Wednesday, a city court ordered Kyivstar to disclose to the police which cellphones were turned on during an antigovernment protest outside the courthouse on Jan. 10.
