Habari is a new blogging platform being developed by
a number of well known people, some of which are fed up with open source, others just looking for new challenges.
The thing about Habari is that is starts from scratch, and today. That means it doesn’t have to worry about a lot of existing legacy code and thus, downward compatibility. It is also being designed from the grounds up, using the latest available technology. Heck, it’s full OOP! It abstracts database access! You can plug in different theme engines (and, of course, there are plugins). In short, it could easily be the greatest thing since pressed words.
I wrote my first patches against Habari trunk today, one fixing a locale bug and making basic i18n work, the other mostly style changes. How could I resist joining the development frenzy!
Find me in the habari-dev group and on the Habari IRC channel, #habari on irc.freenode.net.

Very interesting experiments regarding gravitomagnetism might lead to a unified theory of quantum mechanics and general relativity. I’ll just link the papers and quote the abstracts, you can read a ‘real’ article at rapidnewswire.com:
Local Photon and Graviton Mass and its Consequences
We show that the presently accepted value of the cosmological constant and a correspondingly small graviton mass leads to considerable gravitomagnetic fields around rotating mass densities, which are not observed. The solution to the problem is found by a graviton mass which depends on the local mass density to ensure the principle of equivalence. This solution, derived from Einstein-Proca equations, has important consequences such as the correct prediction of the dark energy density in the universe solving the “cosmic coincidence” problem, a prediction of the Higgs mass in line with present estimates and a correction term for the Cooper-pair mass anomaly reported by Tate among many others. Perhaps the most interesting results are that the vacuum energy density is then proportional to the energy density of matter in our universe; and that coherent matter can be used to engineer the vacuum. Similar results were obtained for the photon mass which is then proportional to the charge density in matter. For the case of coherent matter the predicted effects have been experimentally observed by the authors.
Experimental Detection of the Gravitomagnetic London Moment
It is well known that a rotating superconductor produces a magnetic field proportional to its angular velocity. The authors conjectured earlier, that in addition to this so-called London moment, also a large gravitomagnetic field should appear to explain an apparent mass increase of Niobium Cooper-pairs. This phenomenon was indeed observed and induced acceleration fields outside the superconductor in the order of about 10^-4 g were found. The field appears to be directly proportional to the applied angular acceleration of the superconductor following our theoretical motivations. If confirmed, a gravitomagnetic field of measurable magnitude was produced for the first time in a laboratory environment. These results may open up a new experimental window on testing general relativity and its consequences using coherent matter.
