Scan my horizon as blue turns to black
The sky is gone again
And all beneath are born to die
Insignificant, am I?




UNIVAC Memories

UNIVAC (UNIVersal Automatic Computer) serves as the catch-all name for the American manufacturers of the lines of mainframe computers by that name, which through mergers and acquisitions underwent numerous name changes. The company UNIVAC began as the business computer division of Remington Rand formed by the 1950 purchase of the Eckert-Mauchly Computer Corporation, founded four years earlier by ENIAC inventors J. Presper Eckert and John Mauchly.

UNIVAC 1108 Prices in 1968 (in 1968 dollars)
Model / Description / Price / Installation Fee

3011-95 1108 CPU $566,460 $2,200
7005-72 131 K word Core Memory $823,500 $2,250
5009-00 FASTRAND™ Controller $41,680 $600

4009-99 Console (TTY-35) $29,365 $200

The depreciation of the U.S. dollar since 1968 makes a benchmark of the value of the dollar in those days useful. In 1968, a sporty domestic automobile, the Chevrolet Malibu Sport Coupe with a 307-cid V-8 engine cost US$2663, 696 times less than a megabyte of UNIVAC core memory.

Extensible Firmware Interface

UEFI Official

EFI Intel

The Extensible Firmware Interface (EFI) is a specification that defines a software interface between an operating system and platform firmware. EFI is intended as a significantly improved replacement of the old legacy BIOS firmware interface historically used by all IBM PC compatible personal computers. The EFI specification was originally developed by Intel, and is now managed by the Unified EFI Forum and is officially known as Unified EFI (UEFI).


The original motivation for EFI came during early development of the first Intel-HP Itanium systems in the mid-1990s. PC BIOS limitations (16-bit processor mode, 1 MB addressable space, PC AT hardware dependencies, etc.) were seen as clearly unacceptable for the larger server platforms Itanium was targeting. The initial effort to address these concerns was initially called Intel Boot Initiative and was later renamed to EFI.

EFI specification 1.02 was released by Intel on December 12, 2000. (Version 1.01 was the original issue; it had incorrect legal and trademark information and was quickly withdrawn.)

EFI specification 1.10 was released by Intel on December 1, 2002. It included the EFI driver model as well as several minor enhancements to 1.02.

In 2005, Intel contributed this specification to the UEFI Forum, who is now responsible for its development[4] and promotion. EFI was renamed to Unified EFI (UEFI) to reflect this; most documentation uses both terms interchangeably.

The UEFI Forum released version 2.1 of the UEFI specification on January 7, 2007; as of March 2007, it is the latest publicly available specification. It added and improved cryptography, network authentication, and the User Interface Architecture (Human Interface Infrastructure in UEFI).

Yttrium barium copper oxide

Yttrium barium copper oxide

Yttrium barium copper oxide, often abbreviated YBCO, is a chemical compound with the formula YBa2Cu3O7. This material, a famous "high-temperature superconductor", achieved prominence because it was the first material to achieve superconductivity above the boiling point of nitrogen.

Seventy-five years after the discovery of superconductivity, Georg Bednorz and Alexander Müller, working at IBM in Zurich Switzerland, discovered that certain semiconducting oxides became superconducting at the then relatively high temperature of 35 K. In particular, the lanthanum barium copper oxides, an oxygen deficient perovskite-related material proved particularly promising.

Building on the motif discovered by Bednorz and Müller, Maw-Kuen Wu and his graduate students, Ashburn and Torng at the University of Alabama in Huntsville in 1987 and Paul Chu and his students at the University of Houston in 1987, discovered YBCO. Their work led to a rapid succession of new high temperature superconducting materials, ushering in a new era in material science and chemistry.

YBCO was the first material to become superconducting above 77 K, the boiling point of nitrogen. All materials developed before YBCO became superconducting only at temperatures near the boiling points of liquid helium or liquid hydrogen (Tb = 20.1 K). The significance of the discovery of YBCO is the breakthrough in the refrigerant used to cool the material to below the critical temperature.

Uzak (2002)

Uzak (Distant) The Guardian

Uzak NBC Film

Uzak IMDb (7,6 out of 10)

If ever a film was composed in a minor key, it is this beautiful and sad movie from the Turkish director Nuri Bilge Ceylan, which simply floats like a helium balloon above the middling mainstreamers that have rolled up this week. It attains a clarity and simplicity that lesser film-makers could strain every sinew trying to achieve without ever getting anywhere. To Ceylan, these things are as easy as breathing. Uzak is about loneliness and depression, and particularly the kind of depression suffered by men of a certain age who would cut their tongues out rather than admit they are depressed.

Yet the film itself is, gloriously, the opposite of depressing. It is gentle and deeply humane, and even ventures into an arena of delicate visual comedy with a shy adroitness that Woody Allen might admire. Watching it is like taking a deep draught of cold, clear water. The fact that one of its actors, Mehmet Emin Toprak, died shortly after filming only increases its piquant quality.

Uzak means "distant": an idea whose metaphorical significance matches, though without outstripping, the more obvious sense of physical distance and estrangement. The movie actually forms the third of what could be thought of as a trilogy of autobiographical movies from Ceylan, the first two being The Small Town (1998) and Clouds of May (1999), works which use the director's own friends and family and hometown locations.

Magnetoresistive Random Access Memory

Magnetoresistive RAM Wikipedia

Freescale MRAM

Magnetoresistive Random Access Memory (MRAM) is a non-volatile computer memory (NVRAM) technology, which has been under development since the 1990s. Continued increases in density of existing memory technologies, notably Flash RAM and DRAM kept MRAM in a niche role in the market, but its proponents believe that the advantages are so overwhelming that MRAM will eventually become dominant.

Unlike conventional RAM chip technologies, in MRAM data is not stored as electric charge or current flows, but by magnetic storage elements. The elements are formed from two ferromagnetic plates, each of which can hold a magnetic field, separated by a thin insulating layer. One of the two plates is a permanent magnet set to a particular polarity, the other's field will change to match that of an external field. A memory device is built from a grid of such "cells".

MRAM has similar speeds to SRAM, similar density of DRAM but much lower power consumption than DRAM, and is much faster and suffers no degradation over time in comparison to Flash memory. It is this combination of features that some suggest make it the "universal memory", able to replace SRAM, DRAM and EEPROM and Flash. This also explains the huge amount of research being carried out into developing it.

Early History

* 1955 - Magnetic core memory had the same reading writing principle as MRAM
* 1988 - IBM scientists made a string of key discoveries about the "giant magnetoresistive effect" in thin-film structures.
* 2000 - IBM and Infineon established a joint MRAM development program.
* 2002 - NVE Announces Technology Exchange with Cypress Semiconductor.
* 2003 - A 128 kbit MRAM chip was introduced, manufactured with a 180 nm lithographic process

Plant 42

United States Air Force Plant 42 is a federally owned military aerospace facility in Palmdale, California where aerospace contractors share a common runway complex, and either lease building space from the Air Force, or own their own building outright (commonly referred to as GOCO, or Government Owned Contractor Operated). There are eight separate production sites specially suited for advanced technology and/or "black" program projects. Currently the most well known contractors at Plant 42 are Boeing, Lockheed Martin, and Northrop Grumman.

Located in the southern Antelope Valley, Plant 42 is strategically located near Los Angeles area defense and aerospace contractor companies, as well as Edwards Air Force Base's high-speed test corridors used under the direction of the base's Air Force Flight Test Center (AFFTC). It is 65 miles (105 km) from the LA Civic Center and 37 miles (60 km) from Edwards' flightline.

Current projects

* B-2 Spirit
* F-22 Raptor
* F-35 Joint Strike Fighter (JSF)
* F-117A Nighthawk
* U-2
* B-52
* Global Hawk

Past projects

* Each of the Space Shuttles
* Modernization of the Space Shuttle Columbia's cockpit area
* Lockheed L-1011 Tristar passenger jet
* B-1 Lancer Bomber
* XB-70
* X-15
* SR-71 Blackbird

The property now called Plant 42 was first activated as an emergency air landing strip in 1940 prior to the entry of the United States in World War II. It also provided B-25 training to military aviators during the war. Declared surplus by the federal government in 1946, it became a commercial airport for Los Angeles County. The outbreak of the Korean War in 1950 caused the Air Force to reactivate the property for use in final assembly and flight testing of military jet aircraft.

Both the U. S. Air Force and its aircraft contractors needed a location away from major population centers - due to sonic booms, other noises and security concerns - but close enough to the major centers of aircraft design and production, while having excellent flying weather the year around. The land which became Plant 42 fit the bill perfectly from the perspectives of all the concerned interests in military aircraft and national defense. Consequently, the Air Force agreed to purchase the land from Los Angeles County in 1951. Lockheed put together a master plan for the property per its Air Force contract, and after the approval of this master plan in 1953, the County transferred ownership of the land to the Federal Government in 1954. Since then Lockheed, looked upon with favor by the Air Force at this time, established its permanent presence at Plant 42. Its first step in doing so was to sign a lease in 1956 for 237 acres (1 km²) for use in its Air Force support programs of manufacturing aircraft and flight testing.

Spitzer Space Telescope

Spitzer Space Telescope Wikipedia

Lyman Spitzer

The Spitzer Space Telescope (formerly the Space Infrared Telescope Facility or SIRTF) is an infrared space observatory, the fourth and final of NASA's Great Observatories.

The time frame of the mission will be a minimum of 2.5 years, with 5 or more optimal. In keeping with NASA tradition, the telescope was renamed after successful demonstration of operation, on December 18, 2003. Unlike most telescopes which are named after famous deceased astronomers by a board of scientists, the name for SIRTF was obtained from a contest open to the general public (to the delight of science educators).

Image of Andromeda Galaxy (M31) taken by Spitzer in infrared, MIPS, 24 micrometers.

The name chosen was that of Dr. Lyman Spitzer, Jr., the first to propose placing telescopes in space, in the mid-1940s.

The US$ 800 million Spitzer was launched on Monday 25 August 2003 at 1:35:39 (EDT) from Cape Canaveral Air Force Station on a Delta II 7920H ELV rocket. It follows a rather unusual orbit, heliocentric instead of geocentric, following earth in its orbit, and drifting away from Earth at approximately 0.1 astronomical unit per year (a so-called "earth-trailing" orbit). The primary mirror is 85 cm in diameter, f/12 (i. e. the focal length is 12 times the diameter of the primary mirror) and made of beryllium and cooled to 5.5 K. The satellite contains three instruments that will allow it to perform imaging and photometry from 3 to 180 micrometers, spectroscopy from 5 to 40 micrometers, and spectrophotometry from 5 to 100 micrometers.


* IRAC (Infrared Array Camera), an infrared camera which operates simultaneously on four wavelengths (3.6 µm, 4.5 µm, 5.8 µm and 8 µm). The resolution is 256 × 256 pixels.

* IRS (Infrared Spectrograph), an infrared spectrometer with four sub-modules which operate at the wavelengths 5.3-14 µm (low resolution), 10-19.5 µm (high resolution), 14-40 µm (low resolution), and 19-37 µm (high resolution).

Nasa : Neptune : Triton

Triton is the largest moon of Neptune, with a diameter of 2,700 kilometers (1,680 miles). It was discovered by William Lassell, a British astronomer, in 1846 scarcely a month after Neptune was discovered. Triton is colder than any other measured object in the Solar System with a surface temperature of -235° C (-391° F). It has an extremely thin atmosphere. Nitrogen ice particles might form thin clouds a few kilometers above the surface. The atmospheric pressure at Triton's surface is about 14 microbars, 1/70,000th the surface pressure on Earth.

Triton is the only large satellite in the solar system to circle a planet in a retrograde direction - in a direction opposite to the rotation of the planet. It also has a density of about 2.066 grams per cubic centimeter. This means Triton contains more rock in its interior than the icy satellites of Saturn and Uranus do. The relatively high density and the retrograde orbit has led some scientists to suggest that Triton may have been captured by Neptune as it traveled through space several billion years ago. If that is the case, tidal heating could have melted Triton in its originally eccentric orbit, and the satellite might even have been liquid for as long as one billion years after its capture by Neptune.

It is one of only three objects in the Solar System known to have a nitrogen-dominated atmosphere (the others are Earth and Saturn's giant moon, Titan). Triton has the coldest surface known anywhere in the Solar System (38 K, about -391° Farenheit); it is so cold that most of Triton's nitrogen is condensed as frost, making it the only satellite in the Solar System known to have a surface made mainly of nitrogen ice. The pinkish deposits constitute a vast south polar cap believed to contain methane ice, which would have reacted under sunlight to form pink or red compounds. The dark streaks overlying these pink ices are believed to be an icy and perhaps carbonaceous dust deposited from huge geyser-like plumes, some of which were found to be active during the Voyager 2 flyby. The bluish-green band visible in this image extends all the way around Triton near the equator; it may consist of relatively fresh nitrogen frost deposits. The greenish areas includes what is called the cataloupe terrain, whose origin is unknown, and a set of 'cryovolcanic' landscapes apparently produced by icy-cold liquids (now frozen) erupted from Triton's interior.

Terry Fox (1958 - 1981)

The Terry Fox Foundation

Terry Fox Biography

Terrance Stanley "Terry" Fox, CC (July 28, 1958 – June 28, 1981) was a Canadian humanitarian, athlete, and cancer treatment activist. He became famous for the Marathon of Hope, a cross-Canada run to raise money for cancer research, which Fox ran with one prosthetic leg. He is considered one of Canada's greatest heroes of the 20th century and is celebrated internationally every September as people participate in the Terry Fox Run, the world's largest one-day fundraiser for cancer research.

On November 12, 1976, Fox was driving back home along Port Coquitlam's highway in his green 1968 Ford Cortina. He was distracted by a bridge construction site, and his car slammed into a half-ton truck. Nothing happened to the driver or the truck, and Fox came out of the accident with only a sore right knee.
In 1977, after feeling pain in his right knee, he was diagnosed with osteosarcoma. This is a form of cancer that strikes men more than women, usually around ages ten to twenty-five. Very often the cancer starts at the knee, then works its way up into the muscles and tendons. At the time, the only way to treat his condition was to amputate his right leg several inches above the knee.
In June of 1981, Terry developed pneumonia, and on June 27 he went into a coma. He died on the 28th at 4:35 am which was his favourite hour of running, a year after his legendary run, exactly one month shy of his twenty-third birthday.
Terry's funeral was large and was broadcast live on national television. He is buried in the Port Coquitlam cemetery, near his favourite lookout just outside the cemetery gates.

The running I can do, even if I have to crawl every last mile.

We need your help. The people in cancer clinics all over the world need people who believe in miracles.

I am not a dreamer, and I am not saying that this will initiate any kind of definitive answer or cure to cancer. But I believe in miracles. I have to.

Damon Hill

Damon Hill in 1991

The Hills 4Ever: Damon Hill

Damon Graham Devereux Hill (born 17 September 1960 in London) is a British former racing driver from England.

He was the 1996 Formula One World Champion. As the son of the late double Formula One world champion Graham Hill, he is the only son of a world champion to win the title.

Damon Hill came to professional motorsports relatively late: he began racing motorcycles in 1983 at the age of 23. The following year, he won the 350 cc Clubman's cup at Brands Hatch. In 1985, he moved on to four-wheel single-seater racing with Team Van Diemen in the Formula Ford championship, before moving up into the UK Formula 3 championship in 1986. After three seasons in Formula 3, where he won four races, Hill ascended another tier of open-wheel racing by joining Mooncraft in the International Formula 3000 championship, where, although often competitive, he never won a race.

Hill started his Formula One career in 1992 with the then uncompetitive Brabham team. He took the first of his 22 victories at the 1993 Hungarian Grand Prix for the Williams team the following year. In 1994, he won the British Grand Prix, a race his father had never won in his long and successful career. During the mid 1990s, Hill was Michael Schumacher's main rival for the Formula One Driver's Championship, finishing runner-up in the German's 1994 and 1995 title seasons. The two had a series of controversial clashes on and off the track, including the collision at the 1994 Australian Grand Prix that gave Schumacher his first title by a single point.

Hill took eight victories and eventually the world championship in 1996. Despite this, Williams decided in mid-1996 not to renew Hill's contract for 1997. He went on to record the Jordan team's first ever win at the 1998 Belgian Grand Prix, and came within a few miles of being the only driver to win a Grand Prix for the Arrows team and their Yamaha engine supplier at the 1997 Hungarian Grand Prix. He retired from the sport at the end of the 1999 season, after 122 race starts.

In 2006, Hill became president of the British Racing Drivers' Club, succeeding Jackie Stewart.

Finite Element Analysis

FEA Wikipedia


Finite element analysis (FEA) is a computer simulation technique used in engineering analysis. It uses a numerical technique called the finite element method (FEM). There are many finite element software packages, both free and proprietary. Development of the finite element method in structural mechanics is usually based on an energy principle such as the virtual work principle or the minimum total potential energy principle.

The finite element analysis from the mathematical side was first developed in 1943 by Richard Courant, who used the Ritz method of numerical analysis and minimization of variational calculus to obtain approximate solutions to vibration systems. From the engineering side, the finite element analysis originated as the displacement method of the matrix structural analysis, which emerged over the course of several decades mainly in British aerospace research as a variant suitable for computers. By late 1950s, the key concepts of stiffness matrix and element assembly existed essentially in the form used today and NASA issued request for proposals for the development of the finite element software NASTRAN in 1965.

Princess Mononoke Official

Princess Mononoke IMDb (8,3 out of 10)

Princess Mononoke (Mononoke Hime) is a Japanese animated film by Hayao Miyazaki that was first released in Japan on July 12.

Princess Mononoke also became the highest grossing movie in Japan until Titanic took over the spot several months later. Overall, Mononoke is the third most popular anime movie in Japan, next to 2001's Spirited Away and 2004's Howl's Moving Castle, both also by Miyazaki.

It is a jidaigeki (period drama) set in late Muromachi period of Japan, and centers on the struggle between the supernatural guardians of a forest and the humans who need its resources, as seen by the outsider Ashitaka. "Mononoke" is not a name, but a general term in Japanese for a spirit/god/monster of the natural world.

A prince is infected with an incurable disease by a possessed boar/god. He is to die unless he can find a cure to rid the curse from his body. It seems that his only hope is to travel to the far east. When he arrives to get help from the deer god, he finds himself in the middle of a battle between the animal inhabitants of the forest and an iron mining town that is exploiting and killing the forest. Leading the forest animals in the battle is a human raised by wolves, Princess Mononoke.

Charles Baudelaire (1821-1867)

veinotte.com Baudelaire

Charles Baudelaire was a 19th century French poet, translator, and literary and art critic whose reputation rests primarily on Les Fleurs du mal; (1857; The Flowers of Evil) which was perhaps the most important and influential baudelairepoetry collection published in Europe in the 19th century. Similarly, his Petits poèmes en prose (1868; "Little Prose Poems") was the most successful and innovative early experiment in prose poetry of the time.

Known for his highly contraversial, and often dark poetry, as well as his translation of the tales of Edgar Allan Poe, Baudelaire's life was filled with drama and strife, from financial disaster to being prosecuted for obscenity and blasphemy. Long after his death many look upon his name as representing depravity and vice: Others see him as being the poet of modern civilization, seeming to speak directly to the 20th century.

Silicon-based Light Detector

Technology Review's article

Research@Intel Blog

Researchers at Intel recently announced a silicon-based light detector that, by all measures, is better than those made of more expensive materials. It can detect flashes of light at a rate of 40 gigabits per second, while most of today's fiber-optic networks operate at 10 gigabits per second. The new detector is also more efficient and produces a cleaner signal than other detectors that operate at the same speed. Since detectors made of silicon have the potential to be manufactured on large silicon wafers, through standard processing techniques, researchers could produce detectors that are hundreds of times less expensive than those used in today's networks, which are made of materials such as indium gallium arsenide.

Intel's silicon detectors use the same basic principles that many other light detectors do, explains Paniccia. When photons strike a traditional detector, they produce pairs of electrons and "holes." (A hole is the absence of an electron where one would be expected; it can be thought of as a positively charged particle.) A voltage is applied across the detector, pushing the negatively charged electrons one way, and the positively charged holes the other way. The resulting electrical current provides a measure of the amount of light the detector collected.

Data Matrix

the world as i see it

Data Matrix Wikipedia

Online Datamatrix generator

A Data Matrix code is a two-dimensional matrix barcode consisting of black and white square modules arranged in either a square or rectangular pattern. The information to be encoded can be text or raw data. Usual data size is from a few bytes up to 2 kilobytes. The length of the encoded data depends on the symbol dimension used. Error correction codes are added to increase symbol strength: even if they are partially damaged, they can still be read. A Data Matrix symbol can store up to 2,335 alphanumeric characters.

"Wikipedia, the free encyclopedia"

Data Matrix symbols are square and made of cells, that is little squares that represent bits. Depending on the situation a white module is a 0 and a black module is a 1, or vice versa. Every Data Matrix is composed of at least two finder patterns or handles and two syncs. Handles are two perpendicular lines, coloured the same way as 1 modules, while syncs are like handles with the difference that they are made of alternating black and white modules. Handles achieve a good alignment with the symbol, while syncs sample modules correctly. If the matrix dimension grows, more syncs and handles are added up to 8 both horizontally and vertically. Symbol sizes vary from 8×8 to 144×144.



Facebook, Inc. Wikipedia

Facebook is a social networking website that allows people to communicate with their friends and exchange information. Launched on February 4, 2004, Facebook was founded by Mark Zuckerberg, a former member of the Harvard Class of 2006 and former Ardsley High School student. Initially the membership was restricted to students of Harvard College. It was subsequently expanded to other Boston area schools (Boston College, Boston University, Harvard, Northeastern University), Rochester, Stanford, NYU, Northwestern, and all Ivy League schools within two months. Many individual universities were added in rapid succession over the next year. Eventually, people with a university (e.g .edu, .ac.uk, etc.) email address from institutions across the globe were eligible to join. Networks were then initiated for high schools and some large companies. Since September 11, 2006, it has been made available to any email address user who inputs a certain age range. Users can select to join one or more participating networks, such as a high school, place of employment, or geographic region.

As of July 2007, the website had the largest number of registered users among college-focused sites with over 34 million active members worldwide (also from non-collegiate networks). From September 2006 to September 2007 it increased its ranking from 60th to 7th most visited web site, and was the number one site for photos in the United States, ahead of public sites such as Flickr, with over 8.5 million photos uploaded daily.

The name of the site refers to the paper facebooks depicting members of the campus community that U.S. colleges and preparatory schools give to incoming students, faculty, and staff as a way to get to know other people on campus.
