Anonymous victim HBGary goes to ground

Friday, February 18th, 2011

– Great follow up story to my previous one.  Got to love the Anonymous folks – speaking truth to power.  – dennis

– – – – – – – – – – – – – –

The computer security company hacked by members of activist group Anonymous has gone to ground as further revelations about its activites leak online.

HBGary has cancelled its appearances at public events, saying that members of staff had been threatened.

It follows the release of internal documents which appear to show the firm offered to smear Wikileaks’ supporters.

HBGary officials said the online messages could have been altered prior to publication.

The company’s founder, Greg Hoglund had been scheduled to give a talk at the RSA Security conference in San Francisco this week, but pulled out at the last minute.

The company also withdrew from an associated exhibition.

“In an effort to protect our employees, customers and the RSA Conference community, HBGary has decided to remove our booth and cancel all talks,” it said in a statement posted on its website.

According to e-mails that Anonymous claims to have taken from HBGary’s servers, the company had proposed a plan to undermine Wikileaks.

At the time, the whistleblowing website was planning to release documents relating to Bank of America.

The leaked emails also suggest that HBGary had discovered evidence that US officials were attempting to monitor visitors to websites affiliated to al Qaeda.

These messages have been posted online via the Anonymous-supported site Anonleaks.ru.

Hackers find plan to attack WikiLeaks

Tuesday, February 15th, 2011

– Least anyone wonder, I fully support what Assange’s done.   Governments, and I mean the U.S. especially here, keep far too much secret.   Democracy should be as transparent as it can be consistant with security but most governments err far over that mark.

– So, I applaude Anonymous and their efforts to make the control and suppresdsion of information painful for those who participate in it. – dennis

LONDON – The computer hackers’ collective Anonymous has uncovered a proposal by a consortium of private contractors to attack and discredit WikiLeaks.

Last week Anonymous volunteers broke into the servers of HB Gary Federal, a security company that sells investigative services to companies, and posted thousands of the firm’s emails on to the internet.

The attack was in revenge for claims by the company’s chief executive Aaron Barr that he had successfully infiltrated the shadowy cyber protest network and discovered details of its leadership and structure.

Hacktivists, journalists and bloggers have since pored over the emails and discovered what appears to be a proposal that was intended to be pitched to the Bank of America to sabotage WikiLeaks and discredit journalists who are sympathetic to the whistle-blowing website.

The PowerPoint presentation claims a trio of internet security companies – HB Gary Federal, Palantir Technologies and Berico Technologies – are already prepared to attack WikiLeaks which is rumoured to be getting ready to release a cache of potentially embarrassing information on the Bank of America.

Privacy – not!

Thursday, February 3rd, 2011

– Ever worry about your personal privacy?   Like to keep your address secret?   Love how cute your kids are but would, perhaps, not care to let the entire world know where such cute kids live?   Ever posted pics of your jewelery?    Yes?   Well, I hope you don’t shoot your pics with an iPhone because if you do, you’ve just gotten a whole bunch more to worry about in your life.

– Check out this video:  

– Wonder if such an amazing thing could be true?    It is.   I checked it out with my iPhone and every photo I’ve ever shot has the GPS coordinates of where I shot it embedded in the information that travels with the photo.   Damn!   You’d think on  feature like that, Apple would have set it to ‘off’ unless someone understood the risks and made a conscious decision to turn it “on”.

Cosmic Dioramas…

Monday, October 11th, 2010

– Sorry I haven’t been posting.   I’ve been busy of late and just haven’t felt the urge.   But, that’ll change – it always does.  And I mean, it’s not like there’s nothing of interest going on out there, right?

– Here’s one of the more interesting things I’ve read in a science publication lately.

– It provoked an interesting  side conversation with a friend of mine in which he pointed out that he thought that this new concept would prove ephemeral and frustrating in the same way that Cold Fusion and the search to find the physical laws that underpin Emergence have.   I added Memes to that list and wondered if perhaps the reasons we cannot integrate these ideas into the edifice of science as per E. O. Wilson’s notion of Consilience is because we’ve parsed them out of reality the wrong way and are therefore asking non-sense questions.

Can a mortal ask questions which God finds unanswerable? Quite easily, I should think. All nonsense questions are unanswerable. How many hours are there in a mile? Is yellow square or round? Probably half the questions we ask—half our great theological and metaphysical questions—are like that.   – C. S. Lewis

Metamaterials may offer windows into other world

Move over Harry Potter, and take your invisibility cloak with you. Alice’s looking glass may be the latest bit of literary magic worthy of physics laboratories.

Rather than using substances known as metamaterials to hide objects in plain sight, some scientists instead want to use the strange materials to build windows into worlds with fundamentally different physics. Peering in may reveal how other universes operate and how this universe — the one that avid J.K. Rowling and Lewis Carroll readers reside in — could have begun.

Metamaterials can be engineered to have features very different from those of everyday matter. By altering electric and magnetic properties, scientists can make metamaterials that bend, twist or otherwise manipulate light. The power to turn light in unusual ways brought about a cloaking craze and introduced the possibility of superlenses with unprecedented focusing power.

Last year, a group of physicists at the University of California, Berkeley proposed a type of metamaterial that, if built, could trap light the way a black hole does (SN: 10/10/09, p. 10). The math describing processes in that material resembles the equations governing black holes.

Now Igor Smolyaninov of the University of Maryland in College Park has developed additional “strange schemes,” as he calls them. Metamaterials, it turns out, can serve as broader cosmic dio­ramas, manipulating light to replicate the shape of spacetime.

“In metamaterials, we have a situation in which we have optical spacetime,” Smolyaninov says. “And we can engineer the properties of spacetime.”

Financier Soros gifts $139m to human rights watchdog

Sunday, September 19th, 2010

Continuing a lifelong habit of putting money where his mouth is, George Soros has announced a gift of US$100 million ($139 million) to Human Rights Watch, the organisation which seeks to monitor abuses of power and to lobby transgressing governments and companies.

The billionaire financier – known as the “man who broke the Bank of England” for betting that the pound would drop out of the European Exchange Rate Mechanism in 1992 – said the gift was one of a series he planned to give to liberally minded charities and campaign groups.

The donation will put the once-small group into the same league as organisations such as Amnesty International. It will allow Human Rights Watch to add 120 members of staff to its 300-strong payroll, and almost double its annual budget to US$76 million, meaning it could expand operations in such countries as South Africa, China and India.

The New York-based group, founded in 1978, devotes most of its manpower to forensic investigations into human rights abuses. It then typically publishes hard-hitting reports into the people and organisations who might be held responsible.

Loves me like a rock….

Friday, September 17th, 2010

– No, this isn’t about my apparently impending divorce.

– The other day, I came a cross a news story about the influence that motherly love has on us when we are young.   The story impressed me and I felt that it helped explain some of my observations about the people around me; myself included.   My childhood was not an easy one but I think in the very early years, before it all went to custard, my mother did love me with great compassion and care and I think this is why now, even in the worst of circumstances, I find that I have a deep resilience and self-belief.  From the article:

Being lavished with affection by your mum as a young child makes you better able to cope with the stresses and strains of adult life, say researchers.

As these things tend to do, just a day or so later, another article passed me by in my reading and I saw the same issue from yet another perspective.  In this case, the article was saying that our social ties as adults can boost our survival by as much as 50%.

The benefit of friends, family and even colleagues turns out to be just as good for long-term survival as giving up a 15-cigarette-a-day smoking habit. And by the study’s numbers, interpersonal social networks are more crucial to physical health than exercising or beating obesity.

– We are truly social animals as anyone who has tried to lead a solitary life has found out.   We need to be “observed” as Irvin Yalom says in his book, When Nietzsche Wept.

Throughout this procedure, Nietzsche remained deeply attentive: indeed, he nodded appreciatively at each of Breuer’s questions.  No surprise, of course, to Breuer.   He had never encountered a patient who did not secretly enjoy a microscopic examination of his life.  And the greater the power of magnification, the more the patient enjoyed it.  The joy of being observed ran so deep that Breuer believed the real pain of old age, bereavement, outliving one’s friends, was the absence of scrutiny – the horror of living an unobserved life.

The day after the second of these two articles, I was riding the bus to work and looking at all the people I didn’t know walking the street and musing about it all when Paul Simon’s song, “Loves Me Like a Rock” came on the bus’s audio system.

Oh , my mama loves, she loves me
She get down on her knees and hug me
Like she loves me like a rock
She rocks me like the rock of ages
And loves me
She love me, love me, love me, love me

– It bought tears to my eyes as the several pieces came together for me.  The articles, memories of my mother, my need and love for those with whom I am close to, for my sons and my two wives and all the people who have ever touched the quick of my life.

– I don’t often talk about my spiritual and mystical inclinations here, but they are strong.   When I’ve not forgotten myself, they inform my life with the knowledge that all is love, if we are but open to see it.

– Beyond all the war and death and strife and unhappiness lies something I once wrote about in a poem that I’ll close with:

Paused for a moment on the edge of all the future
all our lives will surely tangle or unweave now
and all of these potentials,
like hands on my shoulder, steady me.
So let it begin and all the rest of my life go on
I no longer wait or care for the past to resurrect itself
this life can be invested in my future now
I can weave and sort my friends and lovers into the days of my life
I want to walk out each day excited
about what could happen again
and care nothing for what has gone by
I’ve been too long tangled with the old ways
so carefully unknotting our lives and feelings
learning that exquisite patience that lies half way
between compassion and self preservation
But, its done… let me depart and begin anew
this time not to bury my freedom with love and security
or to hold myself untouched by love’s whip and passion
I want to find that balance point there in my heart, between…
there, where on the edge of my best,
I can live each day like it was the last
I want to dance to life’s mysteries and paradoxes
as the fountains dance to the wind and the mimes to the crowd
these things are not to weep for
and, sometimes … in those graceful but oh so brief moments,
perhaps in a lover’s eyes or in a passage of my son’s growth
I’ll see something behind it all …
timeless … smiling thru at me
Brother Methuselah, here in all of us as we gamble our lives
untouched yet compassionate … he waits for us to begin
and he smiles at us, a spiritual joy and promise within.

– gallagher – July 4th, 1978.

A New View of Gravity

Friday, September 17th, 2010

Entropy and information may be crucial concepts for explaining roots of familiar force

Explaining gravity to a small child is simple: All you have to say is, what goes up must come down.

Until the kid asks why.

What can you say? It’s just the way things work. All masses attract each other. Maybe to bright middle schoolers you could explain that spacetime is warped by mass. Or, to high schoolers, you could say that without gravity, the laws of physics would differ for people moving at changing velocities. Yet all those increasingly sophisticated answers merely invite another “Why.” As Sir Isaac Newton himself replied in response to similar questions, “hypotheses non fingo.” Which roughly translates as “I don’t have a clue.”

That such a simple question, about so common a phenomenon, has defied a direct answer for centuries might explain why the physics world has been atwitter lately over a novel attempt to resolve the riddle. A flurry of recent papers have examined this new idea, which mixes principles from string theory and black hole physics with basic old-fashioned thermo­dynamics. If this notion is right, gravity turns out to be a special sort of entropy, a result of the same physics that drives matter to give up its organization and order as it succumbs to the laws of probability. Toss in a dash of quantum mechanics and a pinch of information theory, and the universe emerges, governed on a grand scale by pretty much the same principles underlying the elastic pull of a rubber band.

While similar ideas have been suggested before, nobody has expressed the gravity-as-entropy story as intriguingly as theorist Erik Verlinde of the University of Amsterdam in an online paper (arXiv.org/abs/1001.0785v1) that appeared in January. Titled simply “On the origin of gravity and the laws of Newton,” Verlinde’s paper cooks up a mathematical pièce de résistance connecting gravity to thermodynamics. His ingredients include the law of entropy, the physics of black holes and some speculative conjectures on how space stores information about the matter and energy within it. His recipe replicates Newton’s law of gravitational attraction, and then with some additional mathematical seasoning he arrives at Einstein’s general relativity, the modern and undefeated champion of gravity theories. Verlinde’s analysis indicates that gravity emerges from physical dynamics analogous to basic thermodynamic processes. “Using only … concepts like energy, entropy and temperature,” he writes, “Newton’s laws appear naturally and practically unavoidably.”

Take a deep breath – why the world is running out of helium

Sunday, August 29th, 2010

– Not entirely sure if I’ve written on this subject before.   But, if I had money to invest, I can think of three areas where I’d probably focus myself.   Helium, Lithium and the Norwegian Kroner.

– The first two because they are chemical elements and they have unique properties that nothing else can duplicate and they are here in earth in finite amounts and our demand for them is rising.  And looks strongly like it will continue to rise.

– We know where virtually all of the Helium is on Earth is and, as the article documents, we are not conserving it very well while our need for it looks to continue to rise indefinitely.   A good bet, I’d say.

– Lithium is coming into its own because it is an essential ingredient in the zillions of batteries we are soon going to be needing and using for cars; among other things.   Bolivia has a bunch of it and the world’s major corporation are in a lather to get their hands on it.   And Bolivia’s people’s president, is having the audacity to say that the profits and benefits of mining and selling the stuff should accrue to the Bolivian people (can you imagine?).  The CIA took Allende down for far less cheek than this.   Now they are saying that vast amounts of Lithium have been discovered in Afghanistan.  That should prove interesting.

– And then Norwegian Kroners.  Well, the Norwegians are just about the only ones who’ve had vast oil wealth fall on their head that haven’t rushed out to build the world’s tallest building for the country’s ego or a personal ski-jump for each of their citizens.

– Instead, they’ve created one of the world’s largest sovereign wealth funds and then had the audacity to invest it ethically.  An investment that is beating a lot of countries investing in crap.   If I was looking for a stable currency to hold, my money would be on the Norwegian Kroner.

= = = = = = = = = = = = = = = = =

It is the second-lightest element in the Universe, has the lowest boiling-point of any gas and is commonly used through the world to inflate party balloons.

But helium is also a non-renewable resource and the world’s reserves of the precious gas are about to run out, a shortage that is likely to have far-reaching repercussions.

Scientists have warned that the world’s most commonly used inert gas is being depleted at an astonishing rate because of a law passed in the United States in 1996 which has effectively made helium too cheap to recycle.

The law stipulates that the US National Helium Reserve, which is kept in a disused underground gas field near Amarillo, Texas – by far the biggest store of helium in the world – must all be sold off by 2015, irrespective of the market price.

The experts warn that the world could run out of helium within 25 to 30 years, potentially spelling disaster for hospitals, whose MRI scanners are cooled by the gas in liquid form, and anti-terrorist authorities who rely on helium for their radiation monitors, as well as the millions of children who love to watch their helium-filled balloons float into the sky.

What Happens When You Die? Evidence Suggests Time Simply Reboots

Thursday, August 19th, 2010

– I’m not at all sure what to think of this piece.   I do know that ‘time’ is one of the most fascinating subjects to think about.   So fundamental to our very existence and so unfathomable.

– – – – – – – – – – – – – – – –

What happens when we die? Do we rot into the ground, or do we go to heaven (or hell, if we’ve been bad)? Experiments suggest the answer is simpler than anyone thought. Without the glue of consciousness, time essentially reboots.

The mystery of life and death can’t be examined by visiting the Galapagos or looking through a microscope. It lies deeper. It involves our very selves. We awake in the present. There are stairs below us that we appear to have climbed; there are stairs above us that go upward into the unknown future. But the mind stands at the door by which we entered and gives us the memories by which we go about our day. Everything is ordered and predictable. We’re like cuckoo birds who appear through a door each morning. We fancy there’s a clockwork set in motion at the beginning of time.

But if you remove everything from space, what’s left? Nothing. The same applies for time — you can’t put it in a jar. You can’t see through the bone surrounding your brain (everything you experience is information in your mind). Biocentrism tells us space and time aren’t objects — they’re the mind’s tools for putting everything together.

Using idle computer time

Saturday, August 14th, 2010

A lot of today’s computer systems have two and even four processors.   That’s a lot of computing power going to waste that could be doing useful work for someone.

It turns out that there are ways to use this extra computing power.   I’ve been doing it for a decade.  First with the SETI people and then later with the BOINC group.

The other day, one of the programs I contribute computing time to discovered a new and very strange Pulsar.   and

Volunteering your spare computer time doesn’t cost you anything and it might lead to new scientific discoveries, medical cures and who knows what.

Check it out.
