Neither of those is an option for me simply because I don't have either roof type that you describe. Looking around, I see some DIY options in the US, but most of the sites that talk about it suggest not doing it unless you already do it professionally.

Devuan is an attempt to create a distro that does not have an option for systemd. I find it ironic that in criticizing the lack of choice in other distros, they're creating a distro with a lack of choice.

I expect that as more people get used to/grow up with systemd, it will fall by the wayside and turn into a niche distro. That's cool if it happens--lots of niche distros are still around years later--but it's not likely to be taken seriously in enterprise environments.

Kali switched because Debian switched. It's that simple. The OffSec crew is interested in getting tools to run on a base distro so they can focus on the tools and let the upstream distro handle other problems. Since all the work had been done on getting things working with Debian, changing to another distro probably was not viewed as especially desirable (especially since most other distros use or are planning to use systemd anyway).

I'm looking seriously at solar, though the installed cost isn't quite to where I need it (last I checked about a year ago, it was around $3 per watt, and I need it to be below $2.40 per watt). If you have some solid information on DIY, I'd love to look at it, as that would dramatically reduce the costs involved. I'd love for the only labor costs to be the electrician to handle the connectivity.

He's talking about nameplate capacity against power produced, and that solar produces around 20% of nameplate capacity on average over 24 hours whereas coal can produce around the full capacity, though plants usually aren't run at that level for very long as it increases wear and tear.

It does now, as of Kali 2.0, which is based on Debian 8. Its presence can be verified by running dpkg -l | grep systemd to find the installed packages, ps aux | grep systemd to find the processes, and trying to start a service that won't start for some reason to get the notes about running systemctl status something.service to find out what happened.

Most of the services themselves seem to show up in /etc/init.d, though, so there's still lots of init script use.

Neither of these points bother me, though I'm going to have to get used to a few new commands.

According to the US EIA, in 2012, the overnight capital cost per kilowatt (effectively the construction cost) for coal ranged from $2,934 to $6,599, depending on the type and size of the plant. Solar thermal was at $5,067, and photovoltaic was $3,873 to $4,183 per kilowatt, placing it squarely in competition with coal. That was three years ago; since then, solar power installation costs have dropped even further, while coal has likely stayed about the same, or perhaps even increased slightly.

However, it's still a pretty far cry from natural gas. Excluding fuel cells, the overnight costs ranged from $676 to $2095 per kilowatt. Solar would have to drop nearly half from its lower cost to gas's highest cost. It is dropping, and it probably will get there, but I expect that it's not going to be competitive with gas for a few years yet.

Part of the issue now I think is that labor has become a far more substantial part of solar installations, and that's a relatively inflexible amount. For example, if half of the cost of solar is the labor (not sure if it is or not), then even if the panels were free, it would only be competitive with certain kinds of gas plants.

Encryption

Prosecutors Op-Ed: Phone Encryption Blocks Justice 392

New submitter DaDaDaaaaa writes: The New York Times features a joint op-ed piece by prosecutors from Manhattan, Paris, London and Spain, in which they decry the default use by Apple and Google of full disk encryption in their latest smartphone OSes (iOS 8 and Android Lollipop, respectively). They talk about the murder scene of a father of six, where an iPhone 6 and a Samsung Galaxy S6 Edge were found.

"An Illinois state judge issued a warrant ordering Apple and Google to unlock the phones and share with authorities any data therein that could potentially solve the murder. Apple and Google replied, in essence, that they could not — because they did not know the user's passcode. The homicide remains unsolved. The killer remains at large."

They make a case for lawmakers to force Apple and Google to include backdoors into their smartphone operating systems. One has to wonder about the legitimate uses of full disk encryption, which can protect good people from harm, and them from having their privacy needlessly intruded upon.

All Finagle Laws may be bypassed by learning the simple art of doing without thinking.
