To address the summary, the difficulty is in proving certain security aspects, as current models don't fit the assumptions that RIBE models use. In practice, it could be fine.

The article seems to propose a set forward in a scheme to manage the keys by combining two previously proposed methods in a novel way. I can't judge if this is indeed an advance as I am not familiar with this domain. The main advance claimed is that the publicly needed parameters is constant. This suggests that other schemes had an issue in which the public information would keep growing as the number of issued keys and users grew, causing a scaling issue that limited practical, widespread applications. Again, I can't judge if this is indeed correct.

But, as noted, this does require a trusted third party to ultimately decide if a key is valid. Also, a lot of the work seems to be temporally based; the identity is combined with a timespan to create a key that is only use for a given set of time.

It's an interesting idea overall. It avoids the public key problem by making the information you need the channel in which you communicate on. (For example sending a encrypted email in which the key is the email address),

I don't mind the start screen too much, but a proper start menu is a good start, and bringing Metro apps to the desktop is a start. The library for metro application actually has a long of good ideas in it, so expanding it beyond touch applications is a good idea.

The toughest part is that Windows 8/8.1 came with some really noticeable kernel and userland performance improvements. The switching between metro and the desktop is pretty smooth on all the hardware I've used. If they get back the power user desktop functionality, it's a good start back.

I wish that people would stop this silliness about population controls. Have you been asleep for 40 years? Right now, in an age when European politicians are pulling out their hair trying to get people to make more kids, it's hard to find an industrialized country that it making children at the replacement rate. Many countries are actually shrinking, including populous ones like Japan, Italy, Russia, etc. Many more would be shrinking were it not for immigration. In countries like Mexico that are traditional sources of emmitrants, fertility rates are plummeting as well. It turns out that all you need is a bit of prosperity, urbanization and female education, and you can quickly generate negative population growth rates. If there's a reason to worry about global population, it's that we won't have enough kids to care for the world's retired.

While there are many things about startups that are attractive, in the end, it's just a job, not a lifestyle. It's best to work to live, not live to work. These efforts to create all inclusive environments for programmers will just lead to burnout when the bubble pops. And yes, it is a bubble. We don't need yet another mobile social enabled whatsit pieced together quickly.

If this was an environment to create new formal verification tools or other revolutionary software tooling, then I'd be interested. Right now, it seems we are going a bit backwards. It's harder to create a nice UI on the web than it was on the desktop more than ten years ago. In the last few years, this is the first time that my job is becoming harder. For the longest time, editors got better, debuggers got better, frameworks got better and there were more tools for the job than before. Now, there's no real commercial breakthroughs in static analysis, security, formal verification, domain specific languages. It's all just mobile apps with no depth. Sure, this has driven some new useful stuff (say, Hadoop), but when big data is just for marketing and ads, what's the point?

It's a buzzword for demanding federal control of the internet, to remedy the government-caused problem of last mile providers who are protected from competition by local cable monopoly privileges.

All we need to solve the problem of the Comcasts and the Time-warners of the world is to expose them to competition.

Bullshit. It's ILLEGAL, period. Executive orders don't trump acts of congress, and acts of congress don't override the constitution. Every NSA minion involved in collecting this data without a warrant issued by a judge naming a specific person and stating what they're looking for and why, is a CRIMINAL.
