Happy 95th Anniversary, Relativity

physburn 99 Years (120 comments)

I make it 99 years since general relavity was written, and 110 years since special relavity was written, what is so special about the first confirming solar eclipse that marks it the beginning of relavity, the solar eclipse meanly showed that light could be bent by gravity, one of the prediction of general relaivity.

Daylight Saving Time ...

physburn Re:In the UK I think we would be better (310 comments)

Keeping summer time all year round, would lead to it getting dark at 3pm on the winter solistice, that's crazy, want to leave work in the light at much as possible. In the summer its good we have BST, leads to saving on lighting as it doesn't get dark till later, but still wake up for work in the light most of the time. Forget the moaner, i think we have the right time system.

Oracle Quietly Switches BerkeleyDB To AGPL

physburn Re:Berkeley DB is a steaming POS (219 comments)

No Berkeley DB is a fine piece of kit, i spent several months building a web forum system with Berkeley DB as the database. It worked fine, Berkeley did exactly what the API promised with no extra messing about needed. I would recommend Berkeley for simple NoSQL applications.

Iain Banks Dies of Cancer At 59

physburn He will be missed. (141 comments)

I've read almost every thing by him, the culture books make for great reading, complete with chatty star ship Minds. Also loved some of his non sf book, like complicity and Espida (sp?) Street. Yes his book where somewhat dark particularly many of the ending, but also refreshing in parts.

Clues of Life's Origins Found In Galactic Cloud

physburn Re:Fermi Paradox (80 comments)

May be it takes a very long time to evolve complex life, life was single celled for over a billion years, before multicellar life came about, may be that step is even rarer than we throught and earth just got lucky.

NASA's Basement Nuclear Reactor

physburn Don't believe a word (368 comments)

This device is never going to work, converting protons in neutrons in the metal isn't going to happen, the process requires nearly a MeV of energy that isn't there, (and Terahertz waves are no were near a MeV). This is a cold fusion under different name, cold fusion didn't work, and neither does this. Shame on NASA for supporting research so obviously wrong, and previously debunked.

I Reading News Feeds from, for each subject i'm interested in, i tend to filt about to different subjects on different days. If i come up with a subject that's not there, i add it, only takes a minute to add a subject there, because of a funky google mash up to find rss and atom feeds.

Swiss Federal Lab Claims New World Record For Solar Cell Efficiency

Commercial silicon cells from SunPower already get 21% efficiency, the article gives a record for very specific for the type of thin film cell, which is by no means the most efficient in practice.

If Mars ever had chlorophyl containing life, it would have left and oxygen atmosphere which Mars hasn't got. The above AC is right Mars went dry after its first billion years or so, probably some time before earth evolved oxygen producing planet life.

Electric Vehicles can quite simply to engineered for high speed, the higher the voltage on the motor the faster it goes, simple. The only additional consideration is cooling the motor. Batteries can easierly be made ultra thin and stacked to high voltage, enabling very high speed electric cars.

Does no one read the newspaper any more. I choose newspaper, i read the Metro on the way to work and the evening standard on the way home. I probably wouldn't read a newspaper at all, but both those sheet are free, and given out on the london underground.

Russian find a new particle

physburn physburn writes  |  about 2 years ago

physburn writes "The Russian Dubna Nuctron accelerator has reported finded a new elementary particle. The E(38) Boson at 38 MeV, it interacts only with quarks and gluons, but decays (via quark diagrams) into pairs of photons. The particle was previously reported in February from data from the BaBar experiment, and the new data seems to confirm its existence."

76 Signs of Dark Matter

physburn physburn writes  |  about 3 years ago

physburn writes "The BBC is reporting recent results from the Cresst dark matter search in Italy. Between 2009 and 2011, Cresst have seen 67 events, a 4 sigma detection of dark matter particles with a mass of either around 15 GeV or 25 GeV. The results are near those previous results from DAMA and Cogent. So has dark matter finally been found, and if so what is it?"

HT Superconductors to build Grid Interconnect

physburn physburn writes  |  more than 4 years ago

physburn (1095481) writes "Some big and cold is appearing in Clovis, New Mexico. Somewhere in a triangle between, Roswell (UFO), Alberqueue (Left Turn), and Armillo (Do you know the way), a 22.5 square mile, a triangle of High Temperature Superconductor pipeline is to be build. Each leg of the triangle can carry 5GW of electricity. The purpose to load balance and sell electricity between America's three power grids. Previously the Eastern Grid, Western Grid and Texan Grid have been seperate, preventing cheap electricity being sold from one end of America to the other. The Tres Amiga Superstation as it is to be called, will final contact the three grids. The superstation is also design to link renewable solar and wind power in the Grids, and is to use HTS wire from American Superconductor. Some 23 years after its invention today is day HTS came of age.

Not being Employed

Years, a online dot-com company, years of programming experience, and a long CV of previous work, is not getting me a job in the current conditions.
Being out of work for 18 months now, and getting poor.


Feed Distiller

physburn physburn writes  |  more than 5 years ago You might have notice in all my recent post, I've ended with a sig pointing to something called a Feed on a topic related to the post. This is from my Feed aggregation service, Feed Distiller, which has been running for about a year. Feed Distiller take input ATOM/RSS feeds from blogs around the world, merges the feeds, and filters (using advanced statistical word/word pair methods) the items to keep only those on subject. The result is a 8 hourly update web page and a new rss/atom feed. If there's any subject you want to follow, you can make your own Feed Distiller feed for it, we even have a post-screen google search mashup connected to the system, to help find new input feeds. If you run a blog, you might want to add it in to one of our feeds, to get the extra readership. You might (pretty please do), want to display the related feed as a widget on your page.

Feed Distiller been running for a year, is stable, but i'm currently scaling up the engine to handler a lot more feeds. I've an expensive server to run, and i'm not near breakeven yet. So please don't begrudge me the advertising. I enjoying running Feed Distiller it lets me experiment with AI technique, and multithreaded server programming. I also get to keep up on the all the latest news. I'm alway happy when, I find on of slashdot articles, as also been autofound on one of my feeds. For latest news items on Feed Distiller see our press release blog.

As well as Feed Distiller, I also run a number of blogs you might be interested in.

  • Axitronics is about my theory of dark energy, which I believe is explained by a new interaction, similar to the electromagnetic force, but which interacts with neutrinos instead of electrons.
  • The Third Magic is my random musing on any subject
  • Internet Future UK is where I write about, where I think the internet is going (not necessarily, to hell in a hind-cart).
