+ - Universe's dark ages may not be invisible after all

Submitted by StartsWithABang
StartsWithABang writes: The Universe had two periods where light was abundant, separated by the cosmic dark ages. The first came at the moment of the hot Big Bang, as the Universe was flooded with (among the matter, antimatter and everything else imaginable) a sea of high-energy photons, including a large amount of visible light. As the Universe expanded and cooled, eventually the cosmic microwave background was emitted, leaving behind the barely visible, cooling photons. It took between 50 and 100 million years for the first stars to turn on, so in between these two epochs of the Universe being flooded with light, we had the dark ages. Yet the dark ages may not be totally invisible, as the forbidden spin-flip-transition of hydrogen may illuminate this time period after all.

+1 sad but true. unless you're main product is IT services and it's your job to optimize kernels and specify every single package etc., in 90% of the business world it will be CYA/industry standards and move on to the actual work.

This will happen and you'll hear about it every time it does. - "If you want to build Debian without systemd and deal with all the niggly annoying issues that will come out of that and get progressively worse"

The degree of technical confidence is inversely proportional to the level of management.
