MERRY Newtonmas

December 25, 2007 will be Sir Isaac Newton's 365th Birthay.

Newtonmas is a time to celebrate all his achievents. His laws of motion explain the kinematics of our movements. His explanation of the color of light explains the rainbow. From the myth of the apple falling on his head and his theory of gravitation to the invention of The Calculus he has influenced all our lives.

From: http://blog.wired.com/geekdad/2007/12/its-beginning-t.html :

"With the profusion of Christmas-related decorations, sales, and music, I thought it would be nice to offer a different kind of holiday suggestion, either instead of (if you don't celebrate Christmas) or in addition to (if you do) the coming holiday.

Sir Isaac Newton was born on December 25, 1642 (old style), so it seems natural to take advantage of that complete coincidence and celebrate his life and works as Newtonmas. This idea was first introduced to me by my high school Physics teacher, who said that, since we were in a public school and thus couldn't celebrate any religious holidays, we would celebrate Isaac Newton's birthday by singing physics carols ..., and doing some fun experiments. It was long enough ago that I don't remember everything we did, but I recall figuring out what the effect of flushing the toilets in the bathroom above the classroom was on the water pressure in the classroom sink, figuring out how long it would take a Slinky to make it down a set of the school stairs, and—my favorite—watching a Road Runner cartoon to make note of everything that happened that defied the laws of physics.

So it's my suggestion to seize the opportunity to teach your kids some basics of physics. If you have older kids, you could try teaching them the basics of calculus, too. Of all the sciences, I've always thought that physics was the easiest one to teach in a fun way (did you ever do the monkey in a tree lesson?), mostly because you're not generally working with volatile substances or dead animals, so safety is less problematic"

Liberate your documents

odf

ODF: The inevitable format
by T. Colin Dodd

In 1999, a scientist wanted to look at some data from soil samples collected on Mars in 1975 by the Viking lander. He wanted to test a theory about detecting the existence of Martian bacteria and microbes–in other words, finding life on Mars. The scientist thought he would find what he needed on a NASA website somewhere, but it wasn’t that easy. The original data had been misplaced, and when the huge magnetic tapes that stored the data were found, they were “in a format so old that the programmers who knew it had died.” Someone finally found a ream of paper printouts propping a door open and humanity’s understanding of the universe expanded a bit more. The tragic sense that would have accompanied the loss of this knowledge is echoed in accounts of the destruction of the Library at Alexandria, and probably why book-burnings are seen as a sure sign that a society is unhealthy

Of course, not all lost or inaccessible data holds clues to life on Mars, and not every shred of information needs to outlive its creator. Many unreadable documents will never be missed, but responsible public policy demands that government documents–contracts, deeds, or court records that remain in force for decades or even centuries–must be archived and accessible. Whatever the case, when data is stored and shared on legacy or defunct proprietary formats, over time it will either become expensive to access or disappear entirely.

When it comes to digitally creating, sharing, and storing documents, the technology to prevent format-based decay already exists and is in wide (and growing) use. It’s called the Open Document Format (ODF) and if you’re not currently using it, someday you will.

The ODF, an XML-based document markup language, was first developed in 1999 by Stardivision and then by Sun Microsystem’s Openoffice.org project. Conceived as an open alternative to the proprietary document handling software, which then dominated the world, the driving force behind the ODF was the need for a vendor-neutral document format independent of any single application, readable and writable for all, without any royalty of licensing “encumbrances.” It was promoted on the basis that business and taxpayers would save money. An open format would create competition in the document application sphere. All documents could be read and shared by everyone. Nothing could be lost to time or changes in proprietary code or licensing requirements. Matters of great public interest - census data, weather data, public health statistics, investigative reports, court records and basic scientific research, all paid for by taxpayers, would no longer be encoded on a single, proprietary closed-standard format, requiring citizens to pay twice for access to their own information. Using ODF, proponents said, would keep public documents public.

The Organization for the Advancement of Structured Information Standards (OASIS) was formed in 2002 to standardize the format, which was recognized by the International Organization for Standardization (ISO) in 2006. The Open Document Format Alliance was formed in March of 2006 to promote the format, making the public, legal and political case for the adoption of open technology standards to governments and public institutions.

“Red Hat was a founding member of the ODF Alliance and Tom Rabon [Vice President of Corporate Affairs] serves on the executive committee,” says Stephanie McGarrah, outgoing Red Hat Public Policy Manager. “Red Hat works with other executive committee members to coordinate efforts to talk with governments around the world about ODF.”

Although the ODF was launched with a great gust of common sense blowing at its back, the momentum of widespread adoption has been hindered by bureaucratic inertia, local politics, persistent misconceptions (reinforced by opponents) about ODF’s viability and the “dangers” of adoption. Most of the fear, uncertainty and doubt has emanated from one source, on whose proprietary formats most of the world’s documents currently reside.

Opponents of the ODF do not concede its inevitable adoption, and actively lobby against it. It’s not that anyone is against the ODF in and of itself, or finds any real reason to question its necessity. The logic behind the ODF and the transparency of its creation is fairly unassailable. Rather, it is the open standards on which the ODF is based that are most attacked. From the detractors’ point of view, things are just fine the way they are now. The “standard” is theirs. They own the document “market,” and think of it as “territory” they “won” fair and square. They can’t foresee a future without them (that’s not in their business plan), and as long as everybody is already using their applications and formats, why change? Opponents of the ODF devote considerable resources to lobbying legislatures and executive branch IT advisory boards in an attempt to convince them that the adoption of the ODF actually limits choice and harms market-driven efficiency by “locking out” vendors like them. They say migration is expensive, and even argue that adoption of the ODF will limit public access by cluttering the environment with too many “incompatible” formats. And who really trusts all this “free stuff,” anyway?

But proponents like the ODF Alliance have arguments of their own, and most of them come from “Actually, the opposite is true…” school of refutation.

The ODF Alliance contends that open standards actually promote choice and vendor competition by leveling the playing field. The standard is open and freely available for anyone to implement. There is no competition over the format, just the application used to handle it. In this universe, the best applications win. The ODF alliance also points out that implementing or migrating to ODF is no more complicated or costly than periodically upgrading from one version of a proprietary application to the next, and by obviating the need for future upgrades, real money is saved over time. As for accessibility, Open Office (and other ODF-compliant applications) are freely down-loadable and ready to use now. There are no actual compatibility issues, they say, only non-cooperation issues.

“I think that some governments either aren’t aware of ODF or don’t have the technical staff in place who understand the value of ODF,” McGarrah explains. “So, it’s the alliance’s job to spread that message to the people in government who make those decisions.”

But the unshakable argument in favor of using ODF for public documents is the fact that it’s a better deal for citizens and taxpayers in the long run. Using closed-standard, proprietary software for public documents is like buying the proverbial $10,000 toilet seat, or prohibiting the federal government from negotiating better drug prices with pharmaceutical companies on behalf of Medicaid and Medicare patients, or trying to feed an army and rebuild a warzone by awarding secret, non-competitive, no-bid contracts. It’s non-competitive in the worst sense.

Despite opposition, adoption of the ODF is making slow but inexorable headway, and as a greater understanding of the issue is reached by policymakers, the ODF will challenge the standing ubiquity of proprietary formats. Moving the issue forward, Japan recently required that all its ministries contract with software vendors whose applications are built around open standards. Brazil, Poland, Malaysia, Italy, Korea, Norway, France, The Netherlands, Denmark, Belgium, The Commonwealth of Massachusetts, and the Dehli State Government in India have all made commitments in principle to adopting the ODF and, perhaps more importantly, recognizing the imperative of using open standards. The ODF Alliance continues to arm and enlighten policy-makers with the information and tools they need to make recommendations and change policy, but no one promoting the ODF think its widespread adoption is imminent. It will take time.

“These decision makers have a lot of other issues to deal with (i.e. Health care, education, transportation, poverty…) so technology decisions aren’t usually at the top of their lists,” says McGarrah. “Progress has been made on the wider adoption of ODF. Several governments have adopted ODF and are working to implement the standard, but there is a lot of work to do.”

the underground caves of mars

mh

In "http://antwrp.gsfc.nasa.gov/apod/ap070528.html"

we can read

"Black spots have been discovered on Mars that are so dark that nothing inside can be seen. Quite possibly, the spots are entrances to deep underground caves capable of protecting Martian life, were it to exist. The unusual hole pictured above was found on the slopes of the giant Martian volcano Arsia Mons. The above image was captured three weeks ago by the HiRISE instrument onboard the Mars Reconnaissance Orbiter currently circling Mars. The holes were originally identified on lower resolution images from the Mars Odyssey spacecraft, The above hole is about the size of a football field and is so deep that it is completely unilluminated by the Sun. Such holes and underground caves might be prime targets for future spacecraft, robots, and even the next generation of human interplanetary explorers."

Perhaps Paul French (aka Isaac Asimov) knew something.

Do no give away your password

Recently I have received spam from zorpia.

The explanation: Apparently some people are giving away their webmail passwords (hotmaill, gmail, yahoo, aol, etc) , so zorpia managed to search people's email and collect all the addresses in the emails, addressbook, calendar, etc. (with the password they can do almost all they like).

Pretty scaring its it?

(a month ago I have been spammed by "names database")

Sunshine, or true meaning of the word solarisation

ss


og2


Picture1: Film poster

Picture2: Oxigen Generator


Thanks to a nice invitation of Castello Lopes Multimedia I had the fun to go to an avant-avant-premiere screening of the SF film "sunshine".

The film is OK.

I am not going to tell the story, but just to answer to my answers to a serie of question that crossed my mind during the projection.

Q - To lose communications BEFORE the orbit of Mercury. Isn't that completely preposterous

A - Yes with today Sun. Not necessarily with the altered Sun of the movie.

Q - How do they braked the ship after the gravitational slingshot at Mercury, to dock with Icarus I.

A - By heliobraking (cf. aerobraking, lithobraking)

Q- How could some one name Icarus I and Icarus II spaceships send to the sun

A- They are absolutely ignorant of the Greek mythology

Q- Any homage To Kubrik / Clarke

A- Several. First, the strange scenes near the end. Second, "2001", "Thus Spoke Zarathustra", "Friedrich Nietzsche", "God is dead". Third the solarisation.

Q- In the film the sun suffers strange phenomena. Wouldn't such phenomena be detectable in other stars?

A- No necessarily, if it is a rare and transient phase.

my Chronicles from the Sprawl (20/n) - First We Take Manhattan

IMG_4208

I hadn't been to New York for almost 20 years (They sentenced me to twenty years of boredom?). Not even to the airport, in transit - nowadays most flies to the West Cost, from Europe, are direct, over Canada.

And there are so many things to do, so many places to visit.

But last August I land again in the JFK airport and my son took this picture of N.Y. (in the far, far, background) while we were crossing the Bronx Whitestone Bridge, going to Massachusetts (I would eventually return to New York, but only a few weeks later)

Where the picture was taken:

Leonard Cohen - First We Take Manhattan - 1988 album "I'm Your Man"

They sentenced me to twenty years of boredom
For trying to change the system from within
I'm coming now, I'm coming to reward them
First we take Manhattan, then we take Berlin

I'm guided by a signal in the heavens
I'm guided by this birthmark on my skin
I'm guided by the beauty of our weapons
First we take Manhattan, then we take Berlin

(Chorus:)
I'd really like to live beside you, baby
I love your body and your spirit and your clothes
But you see that line there moving through the station?
I told you, I told you, told you, I was one of those

Ah you loved me as a loser, but now you're worried that I just might win
You know the way to stop me, but you don't have the discipline
How many nights I prayed for this, to let my work begin
First we take Manhattan, then we take Berlin

I don't like your fashion business mister
And I don't like these drugs that keep you thin
I don't like what happened to my sister
First we take Manhattan, then we take Berlin

(Chorus:)
I'd really like to live beside you, baby ...

And I thank you for those items that you sent me
The monkey and the plywood violin
I practiced every night, now I'm ready
First we take Manhattan, then we take Berlin


(Chorus:)
I am guided

Ah remember me, I used to live for music
Remember me, I brought your groceries in
Well it's Father's Day and everybody's wounded
First we take Manhattan, then we take Berlin

Dalits


shilpa shetty

So much talk about India. So little talk about the Dalits, perhaps the secret behind the "Indian Success Story"

Why nobody asked the people burning an effigy representing organizers of "Celebrity Big Brother," in Patna, India, Jan. 17, what they think about the Dalits?

my Chronicles from the Sprawl (19/n) - Edward Dean Adams Power Station

IMG_4441

edward dean adams station map1

edward dean adams station map2

I have posted some scenic pictures of he Niagara fall before, but this one is different.

The fall are the far side of the water plane (Canadian Falls, 1/2 far left, Goat Island, 1/2 far right) , and we can not see then because we are at the level of the upper part. Canadian buildings, in the other side of the falls, are very visible in the far side though (the mist in the air, seen near the buildings, is the signature of the falls).

But the main interest of this picture is that it shows the entrance of the in-let canal for the former "Edward Dean Adams Station".

Build near the beginning of last century this was the turning point of the adoption of electricity as one of the main process of redistributing energy.

The place itself is quite abandoned and I had to use some old maps (also shown) and some math to find the place.
