Honestly, I'd say Skype and Google Hangouts are equally invasive. In both cases, your conversation goes through $BIG_CORP's servers and gets data mined. That said, I would trust Google over Microsoft or Facebook - the latter will happily sell my data to other companies, but it's worth more to Google to keep it to themselves.

On a more practical note, I've found Google Hangouts to be the easiest to get working cross platform, and it has better audio/video quality than Skype too. I actually tried using XMPP/Jingle before this, but there are no good FOSS cross platform clients for it - you need to use different software under Windows and Linux, and good luck getting video to work under Windows. Hopefully someone will eventually write a WebRTC frontend for it to simplify things.

Because if the encryption algorithm was vulnerable to a known plaintext attack, it would be considered insecure and not used at all.

The upcoming version of the Qt framework has Android compatibility. I expect this will be soon followed by the port of many KDE applications to Android, especially given that it's got to be much easier than porting them to Windows.

Or even better, Sabayon. All the power of Gentoo, but with binary packages.

Latin/Greek seems like overkill. Why not just use Prolog, or some other logic programming language? Then you'd get the benefits of unambiguous propositional logic, the familiarity of English, and the ability to perform automated queries on the law. Propositional logic is much easier to teach than Latin/Greek, and would probably be beneficial to cover at some point during primary/secondary education anyway.
For an example of how this might work, see the classic 'Colonel West sells missiles to Nono' example. (slide 17 here).

The ethernet on the Raspberry Pi is provided via a USB-to-ethernet chip.[1] USB devices on the Raspberry Pi have been known to give all sorts of problems when there is insufficient power,[2] which was likely to happen if one powered it using a standard compliant hub which only provided 500 mA instead of the requisite 700 mA. Since the network connection was provided via USB, it was also affected.

So, why would anyone buy the product for the initial price? They end up paying the same price as everyone else in the end, but are exposed to additional risk.
This model only makes sense if there is an additional incentive, like with Kickstarter perks.

You can do that already with an FPGA (if you don't mind a clock frequency of ~100 MHz), but good luck finding an open source program to do synthesize the design.

I've been using the latest version of KDE on a Centrino with 768 MB of RAM - complete with the designed for XP sticker. (My previous laptop died and this one is a temp until I get a new one.)
All you have to do is change a single setting to disable Desktop Effects and it runs fine.

From the article:

My (rather limited) understanding of it is that within the field (i.e. to people who actually know what they're talking about), the phrase 'machine learning' refers to the above case; using a training set of real data to develop a model, then applying that model to real problems.

In contrast, Remy takes a (stochastic) traffic model, rather than raw data, which would make it a different kind of AI.

You think the editors read the summaries? You must be new here...

Someone already tried to do this with EOMA-68. How successful it will be remains to be seen.

So presumably, HTTPS would be effective.
