Flowing Along

To the Editors:

As a physicist-turned-software engineer, I always enjoy Brian Hayes's Computing Science column, and his essay in the November-December issue ("Up a Lazy River") was no exception. But as a physicist-turned-software engineer, I noticed something important was missing. In the equation θ = ω sins, s is described as the distance along the stream centerline. But one can't take the sine of one inch, one foot, or one mile; the argument to the trigonometric function has to be dimensionless. What is the scale factor? The width or the depth of the river, or the square root of the cross-sectional area? And how does one account for the variation of the scale factor, whatever it is, with distance along the stream centerline?

Mr. Hayes responds:

My decision to omit the scale factor from that equation was not a careless error but a deliberate one. At the time, I thought that ignoring all questions of dimensions and units would make the mathematical model easier to understand; complaints from several readers have persuaded me I was wrong.

It's common practice when dealing with abstract equations to pretend that all quantities are dimensionless. In a graph of the sine curve, y = sinx, we don't ask about the units of x and y. The simplest of the meander models falls into the same category. There is no natural scale factor; neither the width nor the depth of the river can serve in this role because the model river has no width or depth but only length. There's nothing more to the model than a curve in the plane, defined by the equation θ = ω sins. In this case, however, the argument to the sine function is distance along the curve (s) rather than distance along a coordinate axis (x or y). Apparently, it's harder to view s as a dimensionless quantity than it is x or y.

I certainly could have written the equation with a scale factor, θ = ω sink s. The value of k is arbitrary. Indeed, we can always set k equal to 1 by adopting appropriate units of measure fors, much as physicists often adopt "natural units" in which Planck's constant and the speed of light are numerically equal to 1. Nevertheless, mentioning k explicitly would have caused no harm and would have avoided confusion for some readers.

I should add that the equation really needs a second constant as well: Strictly speaking, it should be written θ = ωsink s + Φ, where Φ defines the phase of the wave. Curiously, no one has objected to the omission of Φ.

American Competitiveness & Economic Diplomacy

share this

Our ability to compete in a global economy, attract the world’s brightest workers and nurture a functional political system is slipping.

This weakness is now at a point where it threatens to erode the pillars upon which America’s national security rests.

Competitiveness-Square-Logo-150x150America’s competitiveness is now a matter of national security.

We need to acknowledge that current policies and objectives in the public and private sector, taken together, dangerously undercut America’s current and future global position through instability, inefficiency and risk.

America’s political and business leaders must understand that improving our nation’s competitiveness is an urgent priority with much higher stakes than is acknowledged today. Improving the country’s competitive position will require much more than assembling disparate policy initiatives and expecting them to deliver success.

Accordingly, ASP examines interrelated elements of American present vulnerabilities: business climate, infrastructure, national debt, labor market and immigration, defense industrial base, as well as education and healthcare. And turning these to the strengths they once were.

In keeping with ASP’s core mission of examining more than military might when assessing national security, the report also reframes one of the recurring questions of international relations: What factors really make us strong and safe?

Billy Joel, “I’ve Loved These Days”

Written by December 16th, 2012 at 11:40 am

While it lacks the big hits of some of the albums that followed it, 1976’s Turnstiles was a turning point in the career of Billy Joel. Joel had recently left Los Angeles to return to New York and decided that he would take charge of his own sound for the first time in his career.

As he told actor Alec Baldwin in an interview in June of this year for New York’s WNYC, Joel’s decision to produce the album himself was one that was necessary at that point. “Turnstiles was recorded in New York,” he said. “I produced it myself, which, in hindsight, was probably not a good idea, but I didn’t want people telling me what band to work with, how to do the songs. I wanted to do it my way.”

That independence ties in well with the album’s overriding theme about the necessity of making decisive life changes as a means of growing up. Joel’s own cross-country move is reflected in songs like “New York State Of Mind” and “Say Goodbye To Hollywood.” Yet the album’s closing track, “I’ve Loved These Days,” might be the album’s most resonant song in that it hints at how such changes are often bittersweet.

The song is essentially one man’s farewell to a lifestyle that is as alluring as it is unsustainable. The narrator is aware of the wayward and transitory nature of this type of living, acknowledging that “We’re going wrong” and that “We know it’s all a passing phase.” As wallets get lighter and bellies get fatter, the messier side of life is kept at arm’s length for as long as possible: “We hide our hearts from harder times.”

Yet Joel is honest enough to accept that the extravagance and excess have their charms, which is why his final verse is a fond remembrance of the time spent among the wine and roses. As such, he requests just a few more moments of indulgence before it’s time to let it all go for good: “A few more hours to be complete/A few more nights on satin sheets/A few more times that I can say/That I’ve loved these days.”

In typical Billy Joel fashion, these heartfelt lyrics are buoyed by a memorable melody that perfectly captures the wistful emotions. Joel might have been writing Turnstiles from the perspective of someone who was happy to be returning home, but “I’ve Loved These Days” proves that such a momentous move is never a clean break.

Billy Joel, “I’ve Loved These Days”

Now we take our time, so nonchalant
And spend our nights so bon vivant
We dress our days in silken robes
The money comes
The money goes
We know it’s all a passing phase

We light our lamps for atmosphere
And hang our hopes on chandeliers
We’re going wrong, we’re gaining weight
We’re sleeping long and far too late
And so it’s time to change our ways
But I’ve loved these days

Now as we indulge in things refined
We hide our hearts from harder times
A string of pearls, a foreign car
Oh we can only go so far
On caviar and cabernet

We drown our doubts in dry champagne
And soothe our souls with fine cocaine
I don’t know why I even care
We’ll get so high and get nowhere
We’ll have to change our jaded ways
But I’ve loved these days

So before we end and then begin
We’ll drink a toast to how it’s been
A few more hours to be complete
A few more nights on satin sheets
A few more times that I can say
I’ve loved these days

4. Ekholm Archaeological Project in Sonora, Mexico

Authors: Emiliano Gallaga Murrieta, M.A., Ph.D.-candidate, University of Arizona

This catalogue features a portion of the archaeological material of the Sonora-Sinaloa Archaeological Survey Project directed by Gordon F. Ekholm (1937-1940), which today is located at the American Museum of Natural History in New York City.

The catalogue originated in a desire to have an image database for the identification of archaeological material while in the field and during material analysis for the first field season of the archaeological project of the Onavas Valley in the Middle Yaqui River Valley, Sonora, Mexico. The lack of research in the area, the absence of published catalogue material in and around the research area, and the opportunity to gain access to the Ekholm collection at the American Museum of Natural History in New York City in the summer of 2003, provided the impetus to create a photographic record of Ekholm's material and develop this catalogue. This work does not show all the material collected by Ekholm; only a selected portion is depicted because the catalogue's original focus lay on the Middle Yaqui River and its surrounding areas. The creation of this catalogue and its publication on the museum's web page begins to show the richness of the museum collections. More importantly, it underscores the importance of and reveals the opportunity in undertaking further analysis and re-analysis of existing, already collected, and stored data and material collections. Consulting archaeological material from previous projects in or around one's area of research facilitates the creation, design, and undertaking of a better research project.

The archaeological material from the Ekholm collection originated from the Mexican states of Sonora and Sinaloa. These states are part of a larger study region, which includes the Mexican states of Chihuahua, Durango, and sometimes the peninsula of Baja California, and the American states of Arizona, New Mexico, the southern portions of Utah and Colorado, and the western portion of Texas. This large region has been given several different names: Oasis America (Armillas 1969; Kirchhoff 1943), La Gran Chichimeca (Di Peso 1974), Aridoamerica (Kirchhoff 1954), the Greater Southwest (Beals 1932), El Noroeste Mexicano, and the International Four Corners (Minnis 1989), depending largely upon which side of the international border one resides. None of these terms are without problematic connotations and for the purposes of this catalogue, I have chosen to employ the modern political divisions of Sonora, Chihuahua, Northwest Mexico, and American Southwest instead (Gallaga and Newell 2004).

History of research

The first reports or descriptions of Northwest Mexico are found in colonial documents, mostly descriptions of the Spanish entradas, such as those by Diego de Guzmán (Heredia 1969), Vasquez de Coronado (Hammond and Rey 1940), Nuñez Cabeza de Vaca (1993), and Francisco de Ibarra (Hopkins 1988). The lack of complex societies and riches, like gold or silver, which the European explorers did encounter in central Mexico, resulted in a diminished push to penetrate the region and comparatively general and limited descriptions of the native population. Nonetheless, the colonial descriptions provide data useful to the archaeologist. On the whole, the cultural and material descriptions of the native communities European missionaries provided are more informative than military reports and early chronicles. Regarding the Yaqui River populations, the documents describe high numbers of natives in the region, the colonization potential of the area, and the interaction between the coastal and the mainland peoples.

During the 19th century, early travelers (Lumholtz 1902), geographers (Bartlett 1965; Brand 1933, 1935, 1943; Sauer and Brand 1930, 1931), and archaeological explorers (Amsden 1928; Bandelier 1890, 1892; Ekholm 1939, 1942; Lister 1958; Noguera 1926, 1930, 1958; Sayles 1936) were among the most important archaeological pioneers who created points of departure for future research in Northwest Mexico. For many years, however, only a handful of archaeologists ventured down this path. Most archaeologists preferred the great temples of Mesoamerica to the south or the ubiquitous and attractive architecture of the cliff dwellings and pueblos of the American Southwest to the north. In fact, many of the early archaeologists who visited the area did so only to study how the past of Northwest Mexico fit with the areas of their primary research interest and never made careers in the Northwest. This is the case of the Gordon Ekholm's research in Northwest Mexico. Regardless, his influence over and contribution to the archaeological knowledge of Northwest Mexico's was considerable and remains highly recognized.

The Sonora-Sinaloa Archaeological Survey Project

At the end of the 1930s, George Vaillant researcher from the American Museum of Natural History in New York conceived, designed, and directed the Sonora-Sinaloa Archaeological Survey Project. Although Vaillant was the director of the project, Gordon F. Ekholm, a former student from Harvard University, was appointed field director of the project and he acquired the collections in the field. The project's main objective was to fill the archaeological gap between the American Southwest and the northern Mesoamerican frontier covering the area from the international border to the Río Culiacan (Ekholm 1942:33). While the researchers achieved their objective, unfortunately, the results of the project remained largely unpublished, with the exception of some general articles about the project (Ekholm 1939) and results about the excavation performed at the Guasave site in Sinaloa (Ekholm 1942). Over the course of three field seasons of six months each between 1937 and 1940, Ekholm registered a total of 175 sites between the Mexican states of Sonora and northern Sinaloa, from which 100 lay in Sonora and the remainder in Sinaloa.

Ekholm collected material from the surface of 106 sites, through excavations undertaken at the largest sites, like the one in Guasave, Sinaloa, and by purchasing existing collections, like the Bringas collection in Soyopa, Sonora (Carpenter 1996; Ekholm 1937-1940).

Bringas collection in Soyopa, Sonora

With the exception of the material from excavations and from private collections, Ekholm mainly encountered ceramics and lithics, though a great variety existed within these artifact categories. Among the ceramic material, plain wares occurred in the greatest numbers, though decorated wares, malacates or spindle whorls, and figurines also appeared. Greater variety characterized the lithic collection with stone axes, ornaments, palettes, agave knifes, reamers, stone bowls, atlatl handles, and arrow points. In addition, some turquoise beads and mica pendants were also recovered.

Malacates (spindle whorls)

Clay figurines

Turquoise beads

Mica pendants

Another common and no lesser important material Ekholm collected was marine shell. Marine shell surfaced as raw material, work in progress, debris, and finished goods, like beads, pendants, tinkers, or bracelets. In general, the great variety of items and material Ekholm encountered illustrates a considerable movement of goods between the coast and the interior, although not to the degree he expected to support a Mesoamerican-American Southwest direct interaction theory (Ekholm 1942: 136).

In terms of temporal affiliation, the majority of the sites Ekholm found he identified as prehispanic, some as Spanish Colonial sites, and others as historic sites belonging to Mexican, Piman, Yaqui, or Mayo groups (Ekholm 1937-1940). Ekholm was able to assign cultural affiliation to less than half of the prehispanic sites registered: 20 to the Trincheras archaeological tradition, 40 to the Rio Sonora tradition, and 14 to the Seri or the Central Coast tradition (Ekholm 1937-1940). Later on, after his excavation at the Guasave site, more than 20 sites were defined or assigned to the Huatabampo archaeological traditions (Carpenter 1996, Ekholm 1942; Pailes 1972, 1994).

The sites Ekholm registered surfaced in different geographical areas, where the prehispanic habitants had exploited different resources and had differed in social and political developments and local and regional interactions. Some sites were located on volcanic hills, covered by stone terraces which had been used as habitation sites, agricultural fields, working areas, or defensive areas. This type of sites and associated material are commonly identified as belonging to the Trincheras tradition. Other sites located on the coast featured mounds made of sand/earth and cultural material with mostly marine shell. Depending on the cultural material found, these shell mounds could be identified as Seri (central coast archaeological tradition), Huatabampo tradition, or Yaquis. In the interior of Sonora, the sites Ekholm discovered typically laid along the river valleys in areas near water sources and agricultural lands, like those of the Rio Sonora tradition. Besides the cultural material dispersed on the surface, stone foundations for houses are often observable. River stones are the most common material for those foundations, however volcanic or slab stones were used as well. In some areas of Sonora, it is possible to assign cultural affiliation to the archaeological sites, but in other instances it is difficult to do so, due to the lack of research in many areas that remain unexplored, like the Yaqui River region. Except for a few large sites, like in Guasave, Sinaloa, or Cerro de Trincheras, Sonora, the settlement pattern of the region was mostly dispersed households identified as rancherías.

The Guasave site

Site 117, Guasave, Sinaloa

Site 117, Guasave, Sinaloa

Ekholm registered this site as number 117 in his survey. The site lies near the town of Guasave, Sinaloa, "on the west bank of the Sinaloa River in the center of an extremely fertile agricultural area" (Ekholm 1942:35). The site consisted of an earth mound of an oval shape 1.5 meters high and around 40 meters in diameter. Because the site was the highest point in the middle of the agricultural fields, local people know the mound as the El Ombligo (the umbilicus)(Ekholm 1942:35). At first, from the material remains, Ekholm thought that the site was a household or a trash midden. After two field excavation seasons and recovering 196 burials, the Guasave site became known as the greatest formal cemetery mound in Northwest Mexico that has been excavated, and remains unparalleled until today. John Carpenter summarizes the results of the excavation at Guasave as:

"The mortuary practices included extended inhumations with heads oriented to the north, south, and west, secondary bundle burials of disarticulated remains, and secondary interment in large plainware burial ollas. Also evident were several cases of dental mutilation represented by notches and filed incisors and canines, and fronto-lambdoidal cranial deformation. Offerings associated with these graves revealed an elaborate material culture, with several pottery types including red wares, red-on-buff, finely incised wares and several types of highly detailed polychrome pottery, alabaster vases, copper implements including bells and a probable earspool, shell, pyrite and turquoise jewelry, paint cloisonné gourd vessels, cotton textiles, ceramic masks, clay smoking pipes, modeled spindle whorls, a cylinder stamp, prismatic obsidian blades, food remains, bone daggers and human trophy skulls." Carpenter 1996:163. Although the Ekholm 1942 publication on the Guasave site provide a good description and analysis of the performed excavation, the material and data still offer several promising venues of research.

Photo collection

In addition to the archaeological collection recovered in this vast territory, Ekholm composed an important photographic record of his discoveries, sites, material collections, excavation pits, communities, and people he encountered on his trip. This amazing photographic archive, more of 300 photos, can be consulted as well in the AMNH collection benefiting not only archaeologies, but historians, architects, or anthropologists as well.

Ekholm photo collection

In many instances, the images captured by his lens no longer exist as such due by land development, intensive agricultural activities, or flooding from dam construction. For example, in examining Ekholm's photographs I came across the images of the churches of Tepupa and Batuc communities long before the construction of the Plutarco Elias Calles dam. They contrasted wonderfully with my own photos and memory from a survey I did with some colleagues in the area in 1999 when we visited the remains of those towns on dry land - a rare occurrence due to the severe drought in the region at the time.

Churches of Batuc and Tepupa

Remains of the Churches

The opportunity to be able to compare the images of the churches before and after the construction of the dam and the subsequent flooding was a wonderful experience and exemplifies the potential of using the Ekholm collection to aid new data collection projects as well as to re-analyze existing data collections.

I thank Dr. Charles Spencer, Dr. Christina M. Elson, and the American Museum of Natural History staff for the access to their collections and their support to make this catalogue possible. I am grateful for the comments and support of Gillian Newell as well as the economic support from CONACYT.

On Board The Norwegian Sky

First Day of the Cruise was truly fun especially for me because it was my first time. This is the Deck 11, the location of the poolside, Garden Buffet, Great Outdoor, Breaker's Bar, Longboard Bar, Outrigger Lounge, Fitness Center, Jacuzzis, Mandara Spa and Salon, Sauna and Steam Room and II Adagio Fine Dining. During this time, we are all checking the areas of the ship and find our way to the Garden Cafe' to eat.We were acquainted to the other guests and most of them are seasoned cruisers. They said that this Freestyle Cruising is the best. One: Norwegian has complimentary dining and that would mean: Guests can eat any time and anywhere to the main dining rooms, casual cafes', self-service buffets, or avail the room service and guests can have the "made-to-order" food available from 5AM to midnight, all for FREE! That is amazing! Guests do not have to pick the time when to eat and of course, you do not have to sit with the same people over and over again! During dining, the dress code is not strict even if you choose the fine dining. Resorts casual and shorts are allowed in all dining areas and venues but, wear your shoes and shirts though. Most of the guests are wearing formal dress in the fine dining, I suggest you have to wear that too. The ambiance is cozy and elegant, you might as well wear a formal attire.
In all honesty, you will never get hungry in a freestyle dining cruises of NCL. If in case you are hungry for food after midnight, you can have the room service and they charge only less than $4 and the food is FREE. Now, that will cost you money in other cruise ship.
The picture above is the Miami city. We sail away at exactly 5PM and the party continues at the poolside for the BBQ! Actually, the activities on the cruise ship started at 11:30AM while the ship was still embarking the guests. There were Sudoku and Crosswords at the Library, Basketball Open Play, Live Music at the Atrium, Kid's Corner is open too, Golf Driving Range for golf enthusiasts, live music at the poolside where we frequent. Guests were just checking really what's ahead of this cruising. Some attended the sky ship tour and listen to the shore excursion presentation. As for us, we just took a table on the Deck 11, eat and mingle with people. It was really interesting and fun.By 4:30 PM, everyone had to proceed to the Assembly Station for Mandatory Life Boat Drill. Our key card has a G name on it and that means we have to find the Station G. I noticed that guests were not taking the drill seriously. It took them a long time to gather the guests to their respective stations. It reminds me the situation of TITANIC where people wanted to be the first on the life boat. Since, this is only a drill few are paying attention. Well, I observe that on the plane too. Anyway, public areas were close and all guests were accounted for at the Assembly Station. If something happens, this life boat above us will be our refuge and it's big. It can accommodate 150 passengers. After the Mandatory Life Boat Drill, we head to the Fwd area of the ship and we stayed right here to watch the Miami City as we sail away. This is the Deck 12 of the Norwegian Sky. The party continues in every Deck of the cruise ship and yap, music is everywhere. It was a gloomy day and it drizzles a bit but, the fun and excitement was sky limit!

I Told You So

Guest written by our friend Trent Horton:

I’m only a hard day’s work away from a relaxing, exciting night with friends. I’ve paid the bills, researched Reliant Texas Electricity Provider for a better rate on our power (Matt’s gonna be so proud), and swept and mopped the floors. At 5PM today, we’re leaving to head to the fair in Houston for a night of fun with friends. Matt has been asking me for years to go – The Charlie Daniels Band is supposed to be playing and he’s obsessed. I have put it off and put it off, but now we actually have a free night while they’re here, so we’re grabbing our jackets and headin’ to the county fair! I grumped about it at first, but now and a little excited about funnel cakes, fried pies, cotton candy, and maybe a ferris wheel ride. That should probably happen before the fried pies, huh? And, if you won’t tell anyone, I’m slightly excited about seeing The Charlie Daniels Band, too. But let’s just keep that one between you and me. Matt’s reeeeeal good at “I told you so”.

Carnival Imagination

While we were in the Norwegian Sky waiting for our schedule to sail to Bahamas, Carnival Imagination started sailing away ahead of us. This ship is a Fantasy Cruise under Carnival Corporation and PLC. It travels to Western Carribean and the Bahamas for three to four days.

On the Cruise

Today, we arrived in Great Stirrup Cay and it is the second day of our cruising to Bahamas. We had a coffee at the Garden Buffet which is located at the 11th floor on the Aft-section of the ship. And, Ron’s daughter came and we all went to the Palace Fine Dining which is located at the Mid-section of the ship. On this area, guests had to wait to be seated which is really nice. Our server is a Filipino from Cebu and most of the workforce on this ship is Filipinos. We gave him extra tip because he was a good server. If the weather permits, we will go to transfer to a tender boat and transport us to the island of GSC. Excited! But, the waves are really big and the wind blows so strong. For safety Reulations, they can cancel this trip to Great Stirrup Cay anytime though. Fingers cross!

Philippines Women's Sabre Fencing Team for SEA Games

Guest Post: Antonio Levy S. Ingles, Jr.,Ph.D.

Dear Friends,

God bless you more!

Please assist a Teacher-Athlete and her teammates in the SEA Games...

Lenita Reyes Otadoy, Joanna Franquelli and Jyllyn Nicanor (Philippines Women's Sabre Fencing Team) have been chosen to compete in the upcoming SEA Games in Jakarta, Indonesia by the Philippine Fencing Association on November 13-18, 2011.

To compete, they have to find sponsors, donors and patrons for their airfares, board and lodging and allowances (pocket money).

Although their training in China is all expense-paid through the Philippine Fencing Association this October, unfortunately there is no more enough budget to shoulder their expenses on the actual days of competition.

Each of them only needs Php 50,000 to pay for the above for their 10 day-stay in Jakarta. They are very much willing to put the company logo of the sponsors, donors and patrons in their uniforms.

Please support them by finding a company/individual to sponsor them. Please Support The Philippines Women's Sabre Fencing Team! Please Support Lenita Reyes Otadoy, Joanna Franquelli and Jyllyn Nicanor!

Professor Reyes-Otadoy PE Faculty of University of the Philippines (and my colleague here at De La Salle - College of Saint Benilde) was recognized as an Outstanding Athlete for bringing honor and glory to the country which she represented in various local and international tournaments and by winning several awards.

Professor Reyes-Otadoy won the Silver Medal in the Annual Dayrit Cup Fencing Championships on June 19, 2009 and the Gold Medal in the same tournament in 2008. She also organized the UP Sabre Fencing Varsity Team which finally won the gold in UAAP.

With great respect,

Antonio Levy S. Ingles, Jr.,Ph.D.

The Greencard

I got my 10 year greencard a week ago! Yayyy! Six months ago, I went to the USCIS to have my fingerprint and picture taken. Then according to my notice, I had to wait six months for the decision. Did you know that I really waited exactly six months?I applied for Petition to Remove the Conditions of Residence in short, I used form I-751. Since I live in Florida, my service center should be in Vermont and the processing time is 6 months. As of today, the fee for this application is $590. If you are planning to apply for I-751, you can do it by following the instructions in USCIS.GOV. It is not complicated. Make sure that you insert the needed requirements, correct payments, sent all the needed proofs, and able to write legibly. Make sure also that you read the instructions carefully. Proof read and re-check your papers. Everything will turn out okay. You do not need to pay a lawyer to do all these stuff! But, if you prefer to have a lawyer, that is your prerogative. Either way, as long as all the documents are true and correct, approval is a positive end result! Good Luck everyone!

Making A Resume

I really need to update my resume because the last time I used it was two years ago. How to Write a Resume is not a problem for me but, I wanted to make a new design in a new template using the Resume Builder. This Website is a good resource for making an impressive resume. They even have sample resume according to the kind of career you want to apply such as Education, Accounting, Human Resources and many more. I have to check it out again and make my new resume this week.

Steve Jobs Dead at 56

My friend died of cancer a week ago at the age of 41. She is just an ordinary person, a teacher by profession and has full of life. In comparison, the Apple co-founder and Chairman, Steve Jobs, famous and the great innovator in this generation, died of cancer at 56. I heard on the news that he was the 42nd richest man in the US and yet, money cannot save him. Scientists still have to find the cure of cancer. Money, can buy the things that make us happy but money, cannot buy good health. Once we are dead, we are gone forever. Cancer is not just one disease but, more than a 100 different types and mostly, it is named after the organ. Cancer is a disease that continues to haunt the living if we cannot find the cure to stop it. We are all vulnerable and no matter how careful we are, cancer will just sprout and before we know it, we are already dying. Of course, life will be stretched a little longer if we have the money to spend for treatments. If we pray harder, there will be miracles and we will be cancer-free. A month ago, we have a friend who died of lung cancer and she never smoke. Cancer can be a genetic cause but, the most alarming is the environmental factor. Well, as long as we live happy, eat fruits and vegetables, do the exercise and choose a healthy lifestyle, we can only hope that we will live healthy until we die of old age. How is that sound?

An Advertising Business

My husband and I have been discussing on opening a new business. We have a notary and rental income business but, with the economic crisis in the country right now, the latter is better. The notary on the other hand is slow maybe because we have so many competitors in the area. But, my sister wants to build her own business too. An Advertising Agency is what she has in mind because she is a people-person. She is good at planning, expert in the arts and graphics, and she knows a lot of people engaged in business. Now, you may ask where she got this idea when she has been enslaving herself as a home-maker for so long. She had been doing her own research, watched videos and those videos gave her inspiration.

She told me to watch this specific video and watch it from the advertising agency website that she recommended. It truly gives me an idea that running advertising agencies can be demanding but, it can also be a lucrative business. If the clients are happy, the advertising agency will reach the mark. I believe that happy clients will turn in happier prospects and the cycle goes on. It is a spiral of overflowing clientele. If that is the turn out of the business then, that can be translated into more income. That is the goal of my sister and she can do the business at home too. If her creative juices would flow well, the family will be proud of her, and we will support her dreams.

Isle in Biloxi

When we had our vacation in Ocean Springs, Mississippi, we are so excited to visit the restaurants and the buffet in the area as well as do the casino hopping. There are at least 9 casinos in Biloxi which is just 5 minutes from Ocean Springs. The pictures below were taken at the ISLE hotel and casino. Cruising the Coast is actually scheduled this week. Participants from all over the state travel to the Gulf Coast and display their vintage cars on the highway. You will be blown away with how That maybe the reason why Woodie, the car below was moved to the main lobby of the Isle Casino. Hmmm...just maybe. Supposedly, this car was displayed in the garage entrance but they move it.
It was a beautiful day an hour earlier but, look at the weather. It was so windy and it looks like a big storm!
You guess it right, that's water flooded the entrance of the hotel.
This is the left side of the lobby and those people were heading out towards the garage.
That is the bar at the entrance of the Isle. This is a good place to watch the NFL games and on the left side is the casino.
Rainy afternoon and so breezy! It is a passing storm and after an hour, the sun shines so brightly again.

Farewell Jena

If someone would ask me if I die today, would I be ready? I would surely answer; I am not ready to die! That is human nature and it holds true to most of us! There is so much in life that we hang on, there is so much to accomplish and most of all, we worry too much of our family that we will leave behind.

If only we have the chance to choose between life and death, we would surely choose life! But when death comes, we cannot ask for another day. It will be the end! No one can vouch us for another week or two. Only God knows when and how we die, and we are all subject to follow our fate. And I, embrace that truth! Our body is sacred and as long as we breathe life in every minute of the day, no matter how tired we are and no matter how terrible our days went by, we owe this gift from the Ultimate Creator of Life.Jena was my co-teacher for 12 years. We taught the first grade and when I was assigned in that school, she was already there making her name to the community. I would say she had the best classroom in the first grade level. Her room was organized, clean and the students were well-behaved. When you need visual aids, she would share what she has and she was a good mentor too.

Jena was a very resourceful person. Most of the time, we were the last person to go home because we had to set the classroom for the class on the next day. When I had to finish something and it's already dark and no one is around the school campus, she would wait for me. Yap! She would keep me company and I can remember vividly that she was there with me the whole time. She lives nearby the school so, there is no rush for her to go home. It was a nice gesture, right?

We talk about everything: school, family, kids, life, love, little naughty secrets and yes, she can keep secrets. As a friend and as a person, she was loved by many and a well-respected teacher in the school and the community. Like you and me, she was neither a perfect friend nor a perfect teacher. Others may despise her, like you and me. No matter how we tried to be a good person, we cannot please everybody. She was the kind of person who stand firm on her ground. She was a very career-oriented and very motivated person. She was full of life, and she respects other people. And at the age of 41, she died of cancer. Rest in Peace Jen.

A Good Token

Happy Teacher's Day! All over the world, schools are celebrating teacher's day as a day to boost the morale of every teacher in the force. School administration and student body prepare gifts in the form of tokens like mugs, lapel pins, fruit baskets, good bags and t-shirts. Somehow, school administration also goes for the awarding of best teachers and giving of plaques. Students shower their favored teacher or teachers with lots of greetings and tokens too. The little ones would make cards and color them according to their desired combination, and hand them to the teacher with a newly picked flower to match. Such a sweet thought! Such actions can be missed altogether, especially if one has stopped or temporarily moved in a different career path.

Anyway, I met this guy some time ago and he was actually looking for the best tokens for his employees. He has this special company with five employees and staff. In a way, they are also basically linked with the education system as they provide tutorials. And they are celebrating their anniversary so he wants a really nice token for each of his admirable work force. And I sort of told him that awarding a lapel pin is much better because that way, he will get to pin it on every employee and they will get to wear them even after that awarding ceremony.

Steve Jobs: the Creative Genius

He gave us the Pixar, Toy Story, Wall-e and Finding Nemo! He is larger than life. He was a successful innovator and the biggest shareholder of Disney so far. All of us, in one way or another benefit the luxury of using the technology invented by Steve Jobs. When we say iPod in 2001, iTunes in 2003, iPhone in 2007 and iPad in 2010, these awesome products boils down to one name- Steve Jobs. He is the 42nd wealthiest American and the chairman of Apple.

He is a Buddhist, a father to 4 and at 56, he died (October 5) losing the battle of pancreatic cancer.

When You Need the Cash Advance

Who would you run to when you need money? Usually, we asked help from our friends and family, right? If we lack the financial resources at a given time, cash advance lenders are willing to give us a helping hand. Well, that is quite right as long as we are capable of paying, right? There are so many financial institutions that offer help for student loans which are granted and shall be paid when the student is able to do so.

When we are at work, there are cash advances and loans available for employees and the payment is staggered. Most lenders offer a consolidated loan so that, instead of paying multiple loans at different rates and at different monthly due dates, one enjoys just one fixed rate at one specific due date. The best lender of all is the company such as the cash store which is very convenient to approach with. To apply for cash advance, title loans and installment loans, the approval is fast. When you are in need of money, you can apply online and get your money on the same day when you visit the store in your area. Are you in need of cash advance loan right now? Check out the Website today!

Fort Walton Beach View

We were driving down the scenic route from Mississippi towards Florida and before sunset, we arrive in Fort Walton Area. We decided to stop and booked a night stay in one of the hotels facing the Gulf. The picture below is my husband. The beach of Fort Walton is so calm at early morning. The white sand and the landscape down below our hotel is truly amazing!Because I had a migraine on this day, I did not go to the beach area. We might come here again next time and spend a night or two. This is truly a beautiful place to unwind and have a good vacation.
Well, you can see that the water is really inviting, the sand is crystal white and the area is so clean.

20-Bit, Pin-Programmable, Ultralow Power Sigma-Delta ADC
Manufactured by:

Product Details

The AD7781 is a complete low power front-end solution for bridge sensor products, including weigh scales, strain gages, and pressure sensors. It contains a precision low power 20-bit sigma-delta (Σ-Δ) ADC, an on-chip, low noise programmable gain amplifier (PGA), and an on-chip oscillator.

Consuming only 330 μA, the AD7781 is particularly suitable for portable or battery-operated products where very low power is required. The AD7781 also has a power-down mode that allows the user to switch off the power to the bridge sensor and power down the AD7781 when not converting, thus increasing the battery life of the product.

For ease of use, all the features of the AD7781 are controlled by dedicated pins. Each time that a data read occurs, eight status bits are appended to the 20-bit conversion. These status bits contain a pattern sequence that can be used to confirm the validity of the serial transfer.

The on-chip PGA has a gain of 1 or 128, supporting a full-scale differential input of ±5 V or ±39 mV. The device has two filter response options. The filter response at the 16.7 Hz update rate provides superior dynamic performance. The settling time is 120 ms at this update rate. At the 10 Hz update rate, the filter response provides better than -45 dB of stop-band attenuation. In load cell applications, this stop-band rejection is useful to reject low frequency mechanical vibrations of the load cell. The settling time is 300 ms at this update rate. Simultaneous 50 Hz/60 Hz rejection occurs at both the 10 Hz and 16.7 Hz update rates.

The AD7781 operates with a power supply from 2.7 V to 5.25 V. It is available in a narrow body, 14-lead SOIC package and in a 16-lead TSSOP package.

High Performance, Digital Output Gyroscope
Manufactured by:

Product Details

The ADXRS453 is an angular rate sensor (gyroscope) intended for industrial, instrumentation, and stabilization applications in high vibration environments. An advanced, differential, quad sensor design rejects the influence of linear acceleration, enabling the ADXRS453 to offer high accuracy rate sensing in harsh envi-ronments where shock and vibration are present.

The ADXRS453 uses an internal, continuous self-test architec-ture. The integrity of the electromechanical system is checked by applying a high frequency electrostatic force to the sense structure to generate a rate signal that can be differentiated from the base-band rate data and internally analyzed.

The ADXRS453 is capable of sensing an angular rate of up to ±300°/sec. Angular rate data is presented as a 16-bit word that is part of a 32-bit SPI message.

The ADXRS453 is available in a 16-lead plastic cavity SOIC (SOIC_CAV) and an SMT-compatible vertical mount package (LCC_V), and is capable of operating across a wide voltage range (3.3 V to 5 V).

  • Rotation sensing in high vibration environments
  • Rotation sensing for industrial and instrumentation applications
  • High performance platform stabilization

EVAL-ADXRS453Z Circuit Diagram

Product Details

The EVAL-ADXRS453Z is a simple breakout board that enables easy connection of an ADXRS450 into an existing system. The ADXRS450 is a digital-output, single-axis gyroscope with built-in temperature calibration.

The ADXRS453 is available in two packages: an SOIC package for yaw-axis rate sensing, and a vertical-mount package (VMP) for pitch- or roll-axis sensing. In applications requiring multi-axis sensing, the innovative VMP greatly simplifies assembly by eliminating the need for additional boards mounted at 90°. Breakout boards are available for the ADXRS450 in both packages, as listed in the Ordering Guide below.

Due to its small size and stiff PCB, the EVAL-ADXRS453Z has minimal effect on performance of the system and of the gyroscope, and thus it is ideal for evaluation of the ADXRS453 in an existing system. Note that the ADXRS453 requires digital communication via SPI. No processor is included with the EVAL-ADXRS453Z; firmware must be supplied externally by the user. For an evaluation system that includes a processor, please see the EVAL-ADXRS453Z-M.

EVAL-MST-ISEB Circuit Diagram

Product Details

The iMEMS® Real Time Eval System is an easy-to-use evaluation tool targeting bench or desktop characterization of Analog Devices, Inc., inertial sensor products. The system consists of the inertial sensor evaluation board (ISEB), or main board, and a satellite board for any Analog Devices inertial sensor product. The ISEB connects directly to a PC via an USB cable, with the USB connection providing both communications and power to the board. The ISEB is connected to the satellite board through a ribbon cable. This cable allows the satellite to be easily manipulated for testing or separately placed into an environmental chamber for temperature or humidity testing. Separating the boards mitigates corruption of data due to the temperature and humidity effects of other components.

The ISEB is an universal main board and is intended to be used with various satellites of Analog Devices inertial sensors, including analog and digital accelerometers, as well as gyroscopes. The different products are evaluated by means of separate GUIs that are customized for performance and characterization measurements relevant to the inertial sensor being evaluated.

The EVAL-ADxZ-M system contains the ISEB and the EVAL-ADxZ-S satellite. Also included is an USB A to Mini-B cable to connect the ISEB to a PC and an 18-inch, 20-pin ribbon cable to connect the ISEB to the satellite.

A glint of light reflects off of the cracked windows, and you instinctively dive to the ground. A split second later, the glass shatters and fragments rain down around you as the bullet misses its intended mark. You roll to the side and watch as dirt and rubble plumes into the air from the spot you so recently occupied. As you marvel at the small particles of dirt scattering into the air, you realize it's already too late; you're too far from cover and the sniper is skilled. As your body slams towards the ground and the scene fades to black, you're glad to know that this was only a game, regardless of how lifelike it appears...

That's not a description of any actual game, but it could be in the very near future judging by the progress we continue to see on the graphics front. The attempt to bring such visions to life is reason enough for us to encourage and revere continued excellence in the field of computer graphics. The ongoing struggle between ATI and NVIDIA to bring forth the most parallel and powerful GPUs at reasonable prices opens new possibilities to developers, pushing them to create content beyond the realm of dreams and move onto ground where angles fear to tread: reality. With each successive generation we work our way closer and closer to blurring the line between reality and rendering, while every step leaves us wanting more. Once again it is time to check in on our progress down the infinite road to graphical perfection.

The latest offering from NVIDIA does not offer a host of new features or any upgraded shader model version support as have the past few generations. The NV4x architecture remains a solid base for this product as the entire DirectX 9 feature set was already fully supported in hardware. Though the G70 (yes, the name change was just to reconcile code and marketing names) is directly based on the NV4x architecture, there are quite a few changes to the internals of the pipelines as well as an overall increase in the width and clock speed of the part. This new update much resembles what we saw when ATI moved from R300 to R420 in that most of the features and block diagrams are the same as last years part with a few revisions here and there to improve efficiency.

One of the most impressive aspects of this launch is that the part is available now. I mean right now. Order it today and plug it in tomorrow. That's right, not only has NVIDIA gotten the part to vendors, but vendors have gotten their product all the way to retailers. This is unprecedented for any graphics hardware launch in recent memory. In the midst of all the recent paper launches in the computer hardware industry, this move is a challenge to all other hardware design houses.

ATI is particularly on the spot after today. Their recent history of announcing products that don't see any significant volume in the retail market for months is disruptive in and of itself. Now that NVIDIA has made this move, ATI absolutely must follow suit. Over the past year, the public has been getting quite tired of failed assurances that product will be available "next week". This very refreshing blast of availability is long overdue. ATI cannot afford to have R520 availability "soon" after launch; ATI must have products available for retail purchase at launch.

We do commend NVIDIA for getting product out there before launching it. But now we move on to the least pleasant side of this launch: price. The GeForce 7800 GTX will cost a solid $600. Of course, we do expect retailers to charge a premium for the early adopters. Prices we are seeing at launch are on the order of $650. This means those who want to build an SLI system based on the GeForce 7800 GTX will be paying between $1200 and $1300 just for the graphics component of their system.

So, what exactly is bigger better and faster this time around? And more importantly, what does that mean for game performance and quality (and is it worth the price)? This is the right place to find the answers. As developers continue to grow in shader prowess, we expect to see hardware of this generation stretch its legs even more as NVIDIA believes this is the point where pure math and shader processing power will become the most important factor in graphics hardware.

    Dude just stfu......we are here to comment what we want and say it freely......minus threats and name i said before this card is not for gamers...maybe elite gamers that have a monitor that does these resolutions but most gamers i know have went to lcd and i have yet to see any lcd[im sure there are some]do these resolutions so this card really is a card for crt elite with those resolutions on a 21 inch monitor you would need binoculars as glasses to play the game....the tanks on bf2 would be ant like small....

    I am SO glad that Anand remains in business despite all the bitches that are in these comment sections.
  • Locut0s - Thursday, June 23, 2005 - link

    Those who are complaining that they should have reviewed at lower resolutions should think for a minute. First of all you are talking about a 600 buck card, most people who have that kind of money to spend on a card also have a monitor that is capable of 1600x1200 or better. Also benchmarking at any lower resolution on a card like this in todays games is almost pointless as you are almost entirely CPU bound at those resolutions. Do you really want to see page after page of 1024x768 charts that differ by only 4-5 percent at the most?

    Also give the editors a break when it comes to writing these articles. As others have said this is not a subscription site and given the number of visitors and the quality of the articles I'm amazed, and gratified, that the people of Anandtech keep putting out article after long article despite all the winning that goes on over spelling mistakes and graph errors that more often than not are corrected within a few hours.

    That's a really great comparison, #112, especially seeing as how we pay for AnandTech and any problems with it could leave us stranded in the middle of nowhere. And so witty, too!

    Jarred, ah, thanks.

    "Our Web Editor is on vacation and we are all doing our own HTML and editing for the next 10 days. In our usual process, the article goes from an Editor to the Web Editor who codes the article, checks the grammar, and checks for obvious content errors. Those steps are not in the loop right now."

    " do know Derek as a very conscientious Editor and I would ask that you please give him, and the rest of us, a little slack this next week and a half"

    Dear Mr. Fink,
    I am sorry to hear about the problems you have had with your vehicle breakdowns. You see, our quality inspector was on vacation that week, so we just shipped our vehicles strait off the assembly line. Please cut us a little slack, as we usually build much better vehicles.

    Buncha Crap,

    my question is how did they do hi res 2048x1536 when the card is only single-link DVI? Shouldn't either an analog connection or dual-link be necessary? Reply

توضيح حول مشروع شرق أوسط واحد

No Comments »

ترددت أخبار مؤخراً تزعم بأني مشارك في مشروع شرق أوسط واحد وأردت التوضيح على موقعي بأني ليس لي علاقة بالمشروع لا من قريب ولا من بعيد، وتفاجأت بوجود رابط موقعي على موقع المشروع وقد طلبت حذفه. كما أن موقع كلنا شركاء استخدم صورتي  دون إذن بدل صورة عبد السلام الذي طلب حذف صورته من الخبر، وقد طلبت من الموقع حذف الصورة أيضاً.

أعيد التأكيد بأني ليس لي علاقة بالمشروع ولن أعلق بأكثر من ذلك.

Putting Syria on the Map

I have been doing some intensive cartography lately. Yes, I’m literally putting Syria on the map.

Going to college in Damascus was a frustrating experience for quite a long time. I did not know the city nearly as well as I should have. I didn’t live in the heart of Damascus, but 30 minutes by servees (a microbus used for commuting in Syria) on a good day. When meeting people in parts of the city that I did not know, I was often too stubborn or too ashamed to ask for directions or help getting somewhere. That always ended with me asking questions to people I’m more comfortable asking, but also less likely to be able to help me; or walking aimlessly and asking people in the street who were as clueless as I was. Going to a new theater or cultural center was always a process of finding out the address and the best way to get to and fro the designated activity location.

Well, not for long. Thanks to Google’s Map Maker, other location-recognition-impaired people won’t have to suffer like I did. I’m now one of a group of volunteer users, or citizen cartographers as Google likes to call them, who  have been drawing the entire map of Syria on Google Map Maker. We’re highlighting points of interest, businesses, streets, neighborhoods and just about everything in between. Eventually it will be available on a high quality, easy to search Google map that’s free to use for all people and platforms that have an active internet connection. There’s an intimidating learning curve to Map Maker; roads are hard to draw and they disappear after you first draw them because they need to be moderated before they show up. This means having to draw roads with no visual clues of your previous work. Drawing on water is a close analogy.

Happy Thursday, folks! I’m taking off early this week {again}. Too much to do this weekend with my husband’s pending trip to Oklahoma and with some new and exciting plans coming ’round. Next week I’m going to be incorporating two completely new posts on my blog: DIY Love and New on Etsy.

DIY Love posts will be all about handcrafting on your own. These posts will be step by step tutorials on how to create fancy paper goods with your own two hands from small party favors to big banners, get ready to become craft obsessed.

New on Etsy will showcase the newest paper goods added to my Etsy Shop {AnastasiaMarieShop} during the week. Not every card and stationery set I post is available for purchasing and not every paper good added to my Etsy shop gets its own post on my blog, so these posts will let you know what’s up for grabs!

To make things easier {I certainly hope that the case} I put together a simple chart to show you what my posting schedule will generally look like throughout the week. There will now be five different categories that will show up every week: Be Inspired, DIY Love, Custom Work, New on Etsy, and The Weekend Post. I’ll be mixing my inspirational palettes with my inspired by posts, and they as a group will now be called Be Inspired {but will still remain to have their own categories.

Posts that fall under the Featured, Giveaways, Guest Blogging, Inspirational Weddings, Real Weddings, and Surveys categories will not be posted on specific days, but whenever.

So I’m definitely looking forward to these new changes! Feel free to share what sorts of DIY projects you’d like to see on this blog!

This week was filled with inspiring images. First we started off with Palette #52: Something Blue, featuring a blue and brown color scheme. And then we were inspired by the lovely Heather Bullard and her oh so pretty styled photographs. And then the black and white vintage airplane photo shoot was too brilliant.

I also showed you a set of thank you cards custom designed for the parents of a bride: With Much Gratitude. But my most favorite post of all was the one saying Happy Birthday to my father, who turned 50 this year! Have you seen it yet? Go back into my dad’s early years

Love the purple is this outdoor wedding via Hey Gorgeous!

This inspirational wedding via The Sweetest Occasion gets me all giddy for spring.

I want to buy a load of this pretty floral tape via Etsy.

Last week I went out for lunch with my sister since my husband was off in Savannah, Georgia on a work-related trip. We made a little stop at Barnes and Noble and I simply fell in love with these new hardcover, leather-bound classics that I found there. I think my next book on my to-buy list is this amazing Chronicles of Narnia one, all the books compacted into one. Isn’t the cover design simply stunning? And it feels so lovely underneath my fingertips. Buy the books in this series via Barnes and Noble.

  • Alla

    Gah, I love that book..the content especially, but that cover is swell too!

  • Tanya

    oooh…love the tape! It really spices up the brown paper and makes it look lovely! Never thought I would want to save tape, but this is just too pretty to throw away!!

  • Anastasia Marie

    Tanya: Oh gosh, I know! I swear I’ll be buying some!
    Alla: we need to make a shopping trip together!

  • Alla

    Shopping trip? Yes, please.

Server Side Includes is an optional feature of the web server which allows text from another file or the output of a program to be included as part of the current web page. This puts more work on the server because instead of just passing the contents of the file to the client, it must search through the text for additional instructions and carry them out.

To tell the we server that you wish to have it look for Server Side Includes you will need to set the execute bit on the permissions of your html file. This can be done by issueing the following command:

	chmod 0755 index.html

One example of what you can do with Server Side Includes is to automatically give the date and time of the last time your page was modified. This can be done by using a line just like this one:

This page last modified < !--#echo var="LAST_MODIFIED" -->.
without the space here   ^

Another use for Server Side Includes is to be able to includes counters that work without generating graphical images. This can be done by includinga something like:

This page has been accessed < !--#exec cgi="./" --> times.
without the space here       ^

Where looks something like:

print "Content-type:  text/plain\n\n";
select(STDOUT); $|=1;
print COUNT "$count\n";
print "$count\n";

Be sure to set the file permissions on like:

	chmod 0755

These examples are configured for use in a personal web page. For departmental pages some changes may need to be made.

Handwriting gestures in Donut

Handwriting gestures in Donut

At the Google I/O event in San Francisco yesterday, Google demonstrated some of the upcoming features of Android 2.0, also known as Donut.

First up was a very Palm Pre/webOS  like combined search function that searches the phone and the internet at the same time, as a user types in a search string.  For example, if you typed in “Oryl” you might find the contact record you had for me in the phone, as well as find a few references to my work on MobileBurn as reported by Google’s search engine.

Another feature shown was on-screen handwriting gestures to navigate long lists.  Engadget has posted some photos of it in action, and you can see that an ‘e’ was written on screen in order to skip ahead in a long list.

Google also showed a translation service and announced that there will be an API available for text-to-speach on Android phones.  Photos after the jump.

Swype beta for Android

For those of you rocking the Swype beta -- ie it did NOT come presinstalled on your phone -- it just got a pretty sizable update. Here's the full changelog:

  • Resolved an accuracy issue that was introduced in the last Beta update. New software features supporting additional languages were included in the beta before the test plan for those features was complete (it is a beta after all). Subsequent testing identified the accuracy issue and corrections made. These new tests have been incorporated into our regression testing to prevent future accuracy issues.
  • Added Double-Tap-to-Edit and Cursor Restore
  • Added microphone button (QWERTY only. Requires Google Voice Search be pre-integrated in your phone’s ROM)
  • Added French & EXPERIMENTAL Chinese Pinyin languages
  • Modified new word priority defaults. The word-choice-window will now be ordered more intelligently when encountering custom dictionary words
  • Fixed a bug where an extra space would be added when replacing a word by Swyping after opening the word choice window
  • Improved the "Hidden-Word" dialog handling so it doesn't show up as often (more improvements to this next time)
  • Improved prediction when handling various path collisions
  • Lots of minor bug fixes

The tl;dr version:  Better, faster, with voice-to-text, finally. Now only if Swype would put this in the market. For those of you already in the beta, head to beta.swype.com/android/get to update your installer. For everybody else, well ... [Swype] Thanks, Sean!

T-Mobile Galaxy Note 2

When we last saw the T-Mobile Galaxy Note 2, it was a late night at CTIA MobileCON in San Diego, and the release date was "this fall". We've seen plenty of hints and rumors about just when it would pop up, and it looks like that time is now.

It's a beastly device. a 5.5-inch 720p display covers a 1.6 GHz quad-core Exynos processor, 2GB of RAM, and a pretty darn good 8MP camera. Combined with the S-Pen and Wacom screen digitizer, the Note 2 is what many folks feel will be the ultimate mobile device. Part phone, part tablet, part artist tool, it's a great mix of features and function wrapped up in a sexy package.

Starting today you can get your hands on one here in the U.S. It comes at a cost, of course, and if you're not familiar with T-Mobile's pricing it can be a bit confusing. The Note 2 will cost $369.99 on a two-year contract, or if you prefer, the full retail will be $649.99.

Check out our hands on and review of the International Galaxy Note 2, and head into the forums to talk this one over!
