If you spend any time working in a reasonably sized It organisation (my four systems at home apply for me, YMMV), you will realise that release management cannot be overstated. Of course if you accept unstable updates system-wide you're going to experience pain, but why on earth are you setting that as a default for something you rely on?
I often build ~amd64 packages, but only because I'm after specific features/fixes in that release, and am uninterested in bleeding-edge elsewhere. Of course the biggest reason I like Gentoo is early access to new versions of packages without dependency hell, but you're understating that benefit simply because you've gone gung-ho. While the ebuilds are not supposed to break (if I understand correctly, the tilde is for applicaiton bugs), you're still off the reservation.
I fail to see the problem. Oh, and if you keep insisting on this approach, may I suggest btrfs for hassle-free rollback? I wouldn't even contemplate a system-wide ~ update without establishing a known checkpoint to fall back on. This seems a problem of your own creation.
It's not dead, but it's no longer free. I work with three volunteer organisations - they're not charities but social groups geared towards helping expats get settled in my city. Membership management, event planning and budgeting, publications and flyers. All were easy to collaborate on with Google Apps, but even the (seemingly) small subscription fees are a burden when we're explicitly non-profit and loosely organised. We could have two active users one month, ten the next, so no single pricing plan option is appropriate without serious overhead and/or possible overspend.
Very unfortunate.
Some people still think there are two parties in Washington instead of two faces of the same party, the Money Party.
Some people are happy to accept that two political parties are all that are required to represent the 3rd largest (by population and expanse) country in the world, with only China governed less diversely at a comparable scale.
Urban and rural poor, wilderness areas of desert forest ice and mountain rivalling countries in expanse, high-finance manipulators, middle-class commuters, academia, greens, industrialists, religious fundamentals of dozens of variants, secular scientists - in Americaland every person in these and all other groups all fit neatly into exactly one of two world-views - Red vs Blue.
The rest of the western world have no idea why Americans think this is acceptable.
Oh, and I've always remembered 3.141592653589. My mother's phone number is a complete mystery...
Here, I'm using Storage System to refer to a design rather than a product.
While filesystems are a good point to look at, I'd be much more interested in the one thing almost all concurrent systems contend over: spindles (or more correctly, drive heads). Partitioning workloads onto separate spindles or SSDs makes a lot more sense than twiddling over the finer points of a filesystem. Serial read/write is well-suited to even slow SATA drives though YMMV, while high-concurrency OLTP DBs benefit from SSD. I can't think of a benchmark that shows any significant performance difference between the headline filesystems when you're not talking about SSD, and if you have the cash to go SSD for all your storage perhaps you should get a professional to advise you better?
My neighbourhood has been a construction zone for about two years as old apartment blocks are ripped down and shiny new ones erected, all with requisite upgrades to infrastructure necessary to support denser settlements. This involves the use of diggers to create trenches, barriers to prevent seepage and pumps running 24/7 to keep flooding minimised. Water (including central heating or stadsverwarming - municipal hot water), sewage, power, gas and telecoms are all laid down in their respective tracks, covered and never paid attention to.
The only time cables or poles are visible is when their function specifically requires elevation, such as overhead power for trains and trams, traffic signals and street lighting and, of course, purpose-built camera poles.
A very interesting interview explores the approach taken here for water management, and the last photo on page one (although unfortunately low-res) illustrates the effect - not a pole or cable in sight. It's actually quite a shock to visit Miami (I was there in March) and see how blighted the average street is.

Then again, I've been using Fedora for years, and haven't felt like I've been anything but a beta tester the whole time.
