Windows Briefcase synchronization problems with Vista
The Briefcase feature in Windows helps you keep your files updated by automatically synchronizing multiple copies of individual files. If you use a desktop computer at the office, and you use a portable laptop computer when you are on the road, Briefcase synchronizes and updates the files on your desktop computer to the modified versions when you reconnect your portable computer to the desktop computer.
The added security layers in Windows Vista create a peculiar problem for synchronizing .ZIP files, .PDF files, .DOC files created by MS Word, and .PCH files created by the C compiler of the MS Development Studio. The problem with the .PDF and .DOC files seems limited to cases when the files are downloaded from an e-mail attachment and stored in a folder that needs to be synchronized.
The problem becomes evident when you try to synchronize a Briefcase and a message appears saying that the file cannot be accessed for copying. Some files such as the .PCH files that can be regenerated by a compiler may simply be deleted from the source folder before the Briefcase is synchronized. However, for other files, the solution is to create a copy of the file, delete the original, and rename the copy to the original name. The reason for the problem seems to be that the files that cannot be copied do not have the "Authenticated Users" security attribute which is required to access a shared resource from another computer in the network. The following images show the attributes of the original which cannot be synchronized and the copy.

 How To Use the Briefcase Feature in Windows XP
Eating raw seafood can make you sick
Raw oysters on the half shell
Many seafood restaurants feature "raw bars" that serve raw oysters on the half shell. Oysters are usually presented six to a plate and served with wedges of lemon and condiments such as hot sauce or shrimp cocktail sauce made from catsup, chili sauce, and horseradish. This dish is nutritious and delicious when the oysters are harvested from clean waters and maintained under refrigeration from the time that they are collected to the time that they are served.
People who eat raw seafood food, such as oysters, sushi, and ceviche risk being infected by tapeworms and roundworms. Raw oysters may also harbor protozoan parasites and bacteria. During the warm summer months the bacterial load of oysters may increase. The Food and Drug Administration issued a warning on August 10, 2007 after at least six people in California and Washington came down with an illness caused by Vibrio parahaemolyticus bacteria. Symptoms of vibriosis include diarrhea, abdominal cramping, nausea, vomiting, fever and chills. The symptoms generally occur within 24 hours of exposure and last about three days.
Raw seafood has some health risks that can be eliminated by cooking. You can learn more by visiting the web site of the Centers for Disease Control which has a database about the life cycle of parasites.
Summer Skin RashSummer skin rashes may be due to a variety of conditions such as insect bites or irritation from poison ivy or other plants. However, most summer rashes are due to yeasts and fungi that live on the skin in hot and humid environments. These rashes generally occur where tight-fitting clothing such as bra straps and jockey shorts are in contact with the skin. Always consult a doctor to get an accurate diagnosis.
A light application of white vinegar once a day with a cotton ball or a spray bottle may eliminate the fungi that cause the rash and help to heal the skin. After the vinegar dries, use talcum powder so that the moisture on the skin can evaporate faster.
Change your underwear daily or whenever it gets wet from sweat. Add chlorine bleach to the washing machine when you wash your underwear, sheets, and towels. Bleach will kill fungi on textiles and prevent them from spreading. If you perspire at night, cover the sheet that you sleep on with a towel, change it at least every other day, and don't sleep in tight-fitting clothing.
Are you getting enough Vitamin D?
Vitamin D metabolism
The Daily Value recommended by the Food and Drug Administration (FDA) for Vitamin D for adults is 10 micrograms per day which is 400 International Units (IU) per day. The current recommendations from the Institute of Medicine call for 200 IU/day from birth through age 50, 400 IU for those aged 51 to 70, and 600 IU for those over 70 years. These recommendations were established by determining the level of Vitamin D that was enough to prevent bone demineralization or rickets. Recent studies have determined that these values may be too low.
Although Vitamin D occurs in some foods, Vitamin D is called the sunshine vitamin because it is created from cholesterol in the skin through the action of ultraviolet rays from the sun. The fear of getting skin cancer by exposure to the sun, the widespread use of sunscreen lotions, and the migration of darkly complexioned people to northern latitudes have all combined to decrease the levels of Vitamin D in the blood of the general population, specially in the winter when the days are short. Deficiency in Vitamin D causes weaker bones which break more easily and accelerate the onset of osteoporosis.
Randomized trials using the currently recommended intakes of 400 IU of Vitamin D/day have shown no appreciable reduction in fracture risk. In contrast, trials using 700-800 IU Vitamin D/day found less fracture incidence, with and without supplemental calcium. The safe tolerable upper intake level for Vitamin D is 10,000 IU/day. Adults should be consuming at least 1000 IU per day of Vitamin D to maintain blood serum levels that are effective for strengthening the bones.

Prevention and treatment of osteoporosis
Osteoporosis is a complex condition characterized by reduced bone mass and weaker bone structure that increases the occurrence of fractures. Although bone strength, bone mass, and bone quality are mostly genetically determined, factors such as nutrition, environment, and life-style also influence bone.
Nutrition is one important way of developing and maintaining bone mass, as well as of preventing and treating osteoporosis. Calcium and phosphorus account for approximately 80-90% of the minerals in bone. A diet for healthy bones requires protein which forms the collagen structure that holds the minerals together, plus calcium, phosphorus, magnesium, zinc, copper, iron, fluoride, vitamins D, A, C, and K. Many of these nutrients are co-dependent and simultaneously interact with genetic and environmental factors.
Exercise is one of the life-style factors that influences bone strength. Weight-bearing exercises have been shown to increase bone density and bone strength. You have to eat right and you cannot be a couch potato if you want to have strong bones.

Antibacterial properties of spices and condiments
Garlic inhibits bacteria
Ever since life emerged on Earth, organisms have been waging chemical warfare against each other. One of the earliest examples was the poisoning of anaerobes by oxygen-producing cyanobacteria 2500 million years ago. The oxygen produced by photosynthetic organisms on the surface of the earth makes life possible for us today, and anaerobes seek refuge in the deep and dark recesses of the biosphere.
For millennia, humans have used salt, alcohol, and vinegar as preservatives for food. Alcohol is the product of fermentation by yeast, whereas vinegar is the result of fungal fermentation. In 1676 Antoni van Leeuwenhoek, the inventor of the microscope, published his first observations of single-celled organisms which now we characterize as bacteria, yeasts, and protozoa. It was only in the nineteenth century that Louis Pasteur's experiments determined that food fermentation was caused by microorganisms that could be killed by heat. In 1945, bacteriologist Alexander Fleming succeeded in isolating the antibiotic substance penicillin from a mold that had contaminated and suppressed growth of his bacterial cultures.
Plants have evolved to defend themselves chemically from insects, yeasts, and fungi. Since ancient times, garlic has been claimed to cure a variety of conditions. Although many claims about garlic remain unconfirmed by modern research, its antibiotic properties can be clearly demonstrated. The Petri dish, above, shows the powerful inhibition of bacterial growth by garlic. A study conducted at the University of California Irvine Medical Center showed that garlic juice, even when diluted significantly, has antibacterial activity against many pathogenic bacteria including antibiotic-resistant staphylococci (MRSA), enterococci, and Pseudomonas.
Eating raw garlic can sometimes provide relief for an upset stomach caused by spoiled food. This remedy can be a tasty treat: Make a sauce by grating half a tomato, add 2 cloves of crushed raw garlic, one teaspoon of olive oil, and a dash of salt and pepper. Spoon the sauce onto a slice of toasted bread, and eat to your health!

Your mortgage loan can affect your retirement income
The Dow Jones industrials dropped more than 500 points over two days as traders in the stock market worried about subprime mortgage loans. The weakening of the housing market has resulted in lower real estate prices and has made it harder to make short-term profits buying and selling homes, apartments, and condominiums. As interest rates have gone up, interest-only loans, negative amortization loans, or variable-rate loans have increased the burden on borrowers who end up defaulting on the loans because they are unable to refinance or sell at a profit.
Many of the borrowers who are now struggling with their mortgage loans could have had a better outcome if they had read and understood the terms of their home mortgage contract. An educated borrower also needs to understand how compound interest and mortgage amortization are calculated. A mortgage amortization schedule provides a detailed description of the principal and interest in each monthly payment during the life of the loan.
When planning your retirement, you need to know when your home will be paid off and how much money you will have in your savings account. An annuity calculator will help you determine the accumulation of capital from a single deposit or from regular deposits. Did you know that you can become a millionaire by investing $180 Dollars per month at 14% interest for 30 years? That is only $45 Dollars per week! You can also save a lot of interest on your home mortgage by paying additional principal in each monthly payment.
Is milk good for your health?
Milk has been getting some negative publicity. People for the Ethical Treatment of Animals (PETA) has a campaign against milk called "milk sucks!" in which they promote vegetarian literature and list illnesses that have been linked to dairy products, including allergies, heart disease, colic, flatulence, breast cancer, autism, etc. The Physicians Committee for Responsible Medicine (PCRM) also states that "many Americans still consume substantial amounts of dairy products -- and government policies still promote them -- despite scientific evidence that questions their health benefits and indicates their potential health risks". The main agenda of PCRM is to convert people into vegetarians.
The truth is that humans are mammals who are supposed to get their nourishment from mother's milk for at least two years. Many people lose the ability to digest lactose, a milk sugar, as they get older, and they develop cramps and diarrhea after drinking milk. One study showed that 19 of 20 Oriental adults were lactose intolerant, whereas only 2 out of 20 Caucasians had this problem.
Milk is a rich source of calcium and protein. Cheeses and fermented milk products, such as yogurt, are nutritious and generally do not cause digestive problems because they have little or no lactose. You do not have to fear milk. People have been herding goats and cattle and surviving on their milk for at least ten thousand years.

Sugar will shorten your life
For some time, scientists have suspected that the increase in insulin level caused by carbohydrates in food can reduce longevity. A recent experiment with genetically altered mice (Irs2 knockout mice) demonstrated that less insulin receptor substrate-2 (Irs2) signaling throughout the body or just in the brain extended life span up to eighteen percent.
Usually, life extension has been achieved only by reducing the calories of the experimental animals. The interesting finding in this study was that it did not matter that the mice were overweight, hyperinsulinemic, and glucose intolerant. The mice with the disabled insulin receptor were more active and displayed greater glucose oxidation than the control mice. The scientists conclude that less insulin signaling in the brain can promote healthy metabolism, attenuate meal-induced oxidative stress, and extend the life span of overweight and insulin-resistant mice.
Some day, there may be a pill to make us live longer, but for now, the best bet is to eat moderately to prevent obesity and avoid the diseases associated with being overweight, such as diabetes, hypertension, and cardiovascular disease.

Checker-playing computer is unbeatable
Professor Jonathan Schaeffer and his team at the University of Alberta have announced that the game of checkers is solved. Dr Schaeffer is a world authority in artificial intelligence applied to computer games. He developed Chinook, the first program to win a human world championship in any game, and this accomplishment is noted in the Guinness Book of World Records.
Checkers became popular in Spain in the mid-16th century. It is a game played between two players by moving 12 red and 12 black pieces on an 8-by-8 square board. The opponent's pieces are eliminated by jumping over them. The player who first runs out of pieces or moves is the loser.
Schaeffer and his team proved that checkers, when played perfectly by both opponents, ends in a draw. The scientists worked for 18 years analyzing 500 billion-billion (5 × 1020) possible combinations of moves to find the perfect strategy in any situation.
