Richard Matthew Stallman is a stubborn man. And it is this trait of his above all else that has spawned the wonderful world of free and open source software, a world that was barely hinted at when he wrote the first document about his intentions. But it's still not Unix

By analysing these planetary systems, researchers from the Australian National University and the Niels Bohr Institute in Copenhagen have calculated the probability for the number of stars in the Milky Way that might have planets in the habitable zone. "Where is everybody?"

1) Most life - even within an actual human - is simple and "intellectually unambitious" bacteria and smaller. I would expect extra terrestrial life to be similar.
2) Any communication (e.g. radio) that is able to leak across galaxies is massively wasteful and it is unlikely that it would be in use for a long period. For example, as soon as humans work out how to do point-to-point communication using neutrinos (or quantum entanglement) that communication would not be detectable.
3) The assumption that because life is found on earth, the conditions of earth are ideal for life is not strictly logical. If you consider the range of environments that bacteria and tardigrades can survive there is a distinct possibility that we are a distant (albeit exciting and productive) outlier of the true "goldilocks condition".
4) The above thoughts are largely the product of a bottle of Italian white wine. Errors and omissions (emissions?) excepted.

That's a pretty good, and wise, bottle of Italian white wine!
Point three... a little quibble. Usually the Goldilocks zone is "liquid water possible", and I still think that - and a largely carbon-based metabolism - are probably commonish. The usefulness, and commonness of those two chemicals are difficult to ignore.
I need more wine to think on this. New corporate policy coming up! :wine: Wait! why doesn't that work? CHRIS!

True - but the Goldilocks zone is "liquid water possible due to solar influence". A radioactive core on a planet or gravitational "squashing" on a large moon orbiting a gas giant would also create liquid water outside that zone.
Also liquid methane / ammonia are also good candidates for supporting a different form of life.

That's long been my opinion. We've anthropomorphised the search for life, by looking for it in our own image, or at least in the image of life on this stone.

Ah true - as they now think with Encaladus/Europa. Good point.
I'm still skeptical about methane/ammonia. It's possible, but Nitrogen just doesn't have the flexibility as a molecule as Carbon. Only three possible bonds - with some of the combinations being highly reactive - limits its use in my mind. Of course, it could just be my mind that's limited. The bacteria search[^] could lead to some interesting (and possibly mind expanding) finds.

The even more mind breaking possibility is that of life existing at a time scale incompatible with our own - for example if something was "alive" but had a metabolism so slow it only changed over tens of thousands of years, could we ever recognise that?

Maybe. We're really good at seeing patterns though (see those who think Earth is 'alive'), and finding stuff that's alive, but definitely wouldn't look like it from the casual observer.
They certainly wouldn't be likely to be detected by SETI, that's for certain.

On a sufficiently large timescale could sand dunes be considered alive?*

I may have to rethink my opinion of Italian whites - they are definitely more inspiring than I remember
We're way deep into really hypotheticals, but I still think it's possible. Given a couple of generations of intense observation, I think we'd notice something was up. For example, the current estimate for carbon cycling on the Earth is 100-200 million years[^]. So we go to some other planet and start observing, and notice that some of these long cycles get diverted into "something". Over similarly long cycles, we notice some sort of signalling (chemical, electromagnetic, or sonic) happens between components of that "something". Our portable pattern matching devices (those grey lumps we all carry) notices that certain messages match certain phenomena, et voila: The Polar Vortex this year is Gaia[^] complaining about fracking
Yup. I think it's half-past wine for me.

I love the tardigrade. Neil DeGrasse Tyson, in Cosmos, said it best: If an alien were to land on earth and do an exhaustive life form scan, it would likely conclude that Earth is a planet of tardigrades, with clusters of additional species here and there.

Call me cynical, but I think it has more to do with the nice weather than non-compete agreements.

These minimum requirements, as outlined by Paul Reed, Senior Program Manager at Microsoft, will need to be met in order to boot and run Windows 10, update and service the OS, as well as deliver a baseline user experience for devices that run the OS, regardless of the make or brand.

Rides are made for children, for enjoyment... But they're always left behind by this lame excuse, "You must be this tall to get on the ride".
These requirements are just so awesome! But I wonder what was that rumor about Windows 10 being of about 1.5GB in size.

During the past few weeks, Microsoft has promised to improve the speed at which Windows 10 builds are released to Insiders. "There's a bad moon on the rise."
OK. I'm not entirely sure why that's the first thing that popped into my head about monthly installs.

I am simply going to turn automatic updated off and then peace of mind will be all mine.

Today we are pleased to announce that MSBuild is now available on GitHub and we are contributing it to the .NET Foundation! What do they have left to open source? Code for the shouty menus in VS?

Nope, their code of conduct is yet to be open-sourced!

Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?
