‘It Can’t Be True.’ Inside the Semiconductor Industry’s Meltdown
“Our first priority has been to have a complete mitigation in place,” said Intel’s Parker. “We’ve delivered a solution.” Some in the cybersecurity community aren’t so sure. Kocher, who helped discover Spectre, thinks this is just the beginning of the industry’s woes. Now that new ways to exploit chips have been exposed, there’ll be more variations and more flaws that will require more patches and mitigation.
"This is just like peeling the lid off the can of worms," he said.

Notes from the Intelpocalypse []
What emerges is a picture of unintended processor functionality that can be exploited to leak arbitrary information from the kernel, and perhaps from other guests in a virtualized setting. If these vulnerabilities are already known to some attackers, they could have been using them to attack cloud providers for some time now. It seems fair to say that this is one of the most severe vulnerabilities to surface in some time.

The fact that it is based in hardware makes things significantly worse. We will all be paying the performance penalties associated with working around these problems for the indefinite future. For the owners of vast numbers of systems that cannot be updated, the consequences will be worse: they will remain vulnerable to a set of vulnerabilities with known exploits. This is not a happy time for the computing industry.

Cowen went golfing and officials dithered as country burned in 2008 -
Lest we forget, the sheer bullshitting ineptitude of Fianna Fail as they managed to shamble into destroying Ireland's economy in 2008:
Once that nasty bit of business was done, the Cabinet departed en masse for six weeks on their summer holidays, despite the emerging economic and financial tsunami. Cowen and family famously took up residence in a caravan park in Connemara as opposed to his 'official' residence at the Mannin Bay Hotel nearby.
When pressed by our reporter Niamh Horan as to why he was not at his station, he defensively replied: "I don't understand it. First the media have a go at me because I'm taking a holiday with my family and then they come down to see if I'm having a good time!" he exclaimed.
