What is RSS?

Posted by cls On May - 2 - 2009

RSS (Rich Site Summary) is a format for delivering regularly changing web content. Many news-related sites, weblogs and other online publishers syndicate their content as an RSS Feed to whoever wants it.

Why RSS? Benefits and Reasons for using RSS: RSS solves a problem for people who regularly use the web. It allows you to easily stay informed by retrieving the latest content from the sites you are interested in. You save time by not needing to visit each site individually. You ensure your privacy, by not needing to join each site’s email newsletter. The number of sites offering RSS feeds is growing rapidly and includes big names like Yahoo News.

What do I need to do to read an RSS Feed? RSS Feed Readers and News Aggregators. Feed Reader or News Aggregator software allow you to grab the RSS feeds from various sites and display them for you to read and use.

A variety of RSS Readers are available for different platforms. Some popular feed readers include Amphetadesk (Windows, Linux, Mac), FeedReader (Windows), and NewsGator (Windows – integrates with Outlook). There are also a number of web-based feed readers available. My Yahoo, Bloglines, and Google Reader are popular web-based feed readers.

Once you have your Feed Reader, it is a matter of finding sites that syndicate content and adding their RSS feed to the list of feeds your Feed Reader checks. Many sites display a small icon with the acronyms RSS, XML, or RDF to let you know a feed is available.

Mulla Nasruddin

Posted by cls On May - 2 - 2009

Once, the people of The City invited Mulla Nasruddin to deliver a khutba.

When he got on the minbar (pulpit), he found the audience was not very enthusiastic, so he asked “Do you know what I am going to say?”

The audience replied “No”, so he announced “I have no desire to speak to people who don’t even know what I will be talking about” and he left.

The people felt embarrassed and called him back again the next day.

Once again he asked the same question – “Do you know what I am going to say?”

This time when he asked the same question, the people replied “Yes” So Mullah Nasruddin said, “Well, since you already know what I am going to say, I won’t waste any more of your time” and he left.

Now the people were really perplexed. They decided to try one more time and once again invited the Mullah to speak the following week.

Once again he asked the same question – “Do you know what I am going to say?”

Now the people were prepared and so half of them answered “Yes” while the other half replied “No”. So Mullah Nasruddin said “The half who know what I am going to say, tell it to the other half” and he left!

Web Surfing Shortcut Keys

Posted by cls On May - 2 - 2009

What is a Web?

The World Wide Web (www) is the most popular extension of the Internet, the global electronic communication network; Information is presented on ‘pages ‘ made accessible through program called browsers. Common browsers include Firefox, Netscape, Internet Explorer, Mosaic and Lynx. The information provided reflects the activities, interests and frequently personalities of those who host the pages -from recreation and research areas through to full blown publication, art galleries and sound studios. Web pages are usually designed in such a way that the reader can effortlessly follow ‘links’ to related subjects, information or files. The links could be pointing to somewhere else on the same page or half a world away.

What are web pages?

The latest rage, of course, is to have your own Home Page on the”World Wide Web” [www] just is a fancy name for the computers on the Internet that support Hyper Text Transfer Protocol [HTTP]. This is an FTP based program that operates on images and text in a simultaneous download. Web Page sites use more bandwidth than any others, because those images each take as much space and time as downloading a smaller book.Each and everytime you access a new Web Page. If you have just accessed pages then a review of that page might come from your disk cache; this is why you will see your disk light trashing so much when you do any viewing of images. . .it is saving all the images, in case a particular image is called up again. This is much faster than downloading the images again, but would wear the hard drive much faster. If you listen closely for hard drive head thrashing, you know what we mean.Being cautious with what you download will not only preserve the bandwidth and access for everyone else, but will also preserve a hard drive a lot longer, presuming it dies from usage as opposed to those that are dropped or hit by lightning or kill motors.You can do your part to reduce this wastage, by optimizing those pictures you do include on your Web Pages. . .jpg files are easy to optimize.

Who uses Web?

Exact usage numbers are impossible to determine. Millions of people surf the internet in more than 186 countries on regular basis. In the beginning, the main users and authors were academic ( relating to the origin of the internet ), but now the trend towards wider involvement is from companies, societies and individuals. The numbers of host computer have increased from negligible numbers in to millions. Currently more than 20 million host computers are estimated to be connected to the www.

What is an idiom ?

Posted by cls On May - 2 - 2009

An idiom is a combination of words that has a meaning that is different from the meanings of the individual words themselves.

It can have a literal meaning in one situation and a different idiomatic meaning in another situation. It is a phrase which does not always follow the normal rules of meaning and grammar.

To sit on the fence ,
it literally means that one is sitting on a fence. I sat on the fence and watched the game. However, the idiomatic meaning of to sit on the fence is that one is not making a clear choice regarding some issue.

The politician sat on the fence and would not give his opinion about the tax issue.
Many idioms are similar to expressions in other languages and can be easy for a learner to understand. Other idioms come from older phrases which have changed over time. To hold one’s horses means to stop and wait patiently for someone or something. It comes from a time when people rode horses and would have to hold their horses while waiting for someone or something.

“Hold your horses,” I said when my friend started to leave the store.
Other idioms come from such things as sports that are common in the United Kingdom or the United States and may require some special cultural knowledge to easily understand them.To cover all of one’s bases means to thoroughly prepare for or deal with a situation. It comes from the American game of baseball where you must cover or protect the bases.

I tried to cover all of my bases when I went to the job interview.

What is MP3

Posted by cls On May - 2 - 2009

MPEG layer 3 is a type of audio codec where processed by significant compression from the original audio source with very little loss in sound quality.

The compression up to 12:1 produces a very little degradation. Tighter compression can be achieved, but it will effect in sound degradation results.To obtain certain compression, we must adjust the bit rates. The standart bit rates (near cd quality result) is 128 or 112 kbit/s. Many people claim that low-rate MPEG layer 3 files sound better than Real Audio files with similar bit rates.

The advantage of MP3 is that it can be broken up into pieces, and each piece is still playable. The feature that makes this possible (headerless file format) also means that MP3 files can be made to stream across the net real-time (assuming the playback bitrate and speed of the Internet connection are compatible).

Exercises in Pregnancy

Posted by cls On May - 2 - 2009

Exercise during pregnancy prepare you for childbirth and exercising after get back you in shape.

Pregnancy is an opportunity for mothers and grandmothers to pamper their little girls who are ‘to-be-mothers’ with the most indulgent recipes handed down through generations. Indian parents travel across the globe to be with their daughters during their pregnancy, to keep them “safe” (which often translates as “immobile”), and to help them with their life changes post-delivery. It is a brilliant practice but one that might require some modifications to accommodate today’s lifestyle.

Pregnancy is not a disease that needs to be treated or cured. There are symptoms like dreadful nausea and vomiting as well as the dizziness and fatigue; the mood swings that don’t seem to let up. The backache, peripheral oedema, insomnia, heartburn and sheer exhaustion in the latter months are, for many, a critical component of being pregnant. Being well informed, equipped, mature and, sometimes, just plain accepting might prove to be the only sensible way to get through what might not be the most comfortable nine months in your life.

So what can you do to ease your symptoms and perhaps transform these months into comfort that could prove to be more meaningful than simply painful and trying?

Planned exercise

For being fit before a planned pregnancy requires more than just an amorphous plan. While a positive attitude in looking forward to a joyful pregnancy and easy delivery goes a long way to keep you optimistic, it is not sufficient to ensure that you have the emotional and physical endurance, the training and knowledge to adapt to unpredictable developments during pregnancy.

According to ACOG (American College of Obstetrics and Gynaecology), exercise during pregnancy can help prepare you for pregnancy and childbirth; exercising after can help you get back in shape.

Being pregnant is only the beginning of a long journey into motherhood. The journey does not end with the delivery of the baby; instead, it’s only just getting started!

It is necessaryl to understand that you need to train your body to accommodate another living being and adapt to the various physiological, hemodynamic and structural changes that it undergoes during those nine months. This training should ideally begin well before getting pregnant. If it has not been initiated already, then it is never too late to begin in pregnancy under the vigilant supervision of a qualified professional.

Having the option of planning a pregnancy allows women time to train optimally for the marathon of pregnancy and labour. This is especially the case for the urban women today who choose to have children later in their lives.

Being older brings about a greater level of emotional maturity (most of the time!), it can be harder physically, not to mention the statistically higher incidence of bringing forth children with chromosomal anomalies. Training to stay strong and gathering the resources required for a healthy pregnancy becomes even more imperative in these cases.

There have been some concerns about the safety of exercise in pregnancy and the weight of the child at birth. However most studies show that well monitored exercise can benefit the mother provided the necessary precautions are heeded.

Fitness in pregnancy, delivery and after requires a thoughtful consideration of Exercise and Fitness; Diet and Nutrition, One’s Emotional/ Mental status. Exercise in pregnancy is also categorised into the Aerobic component, Strength training and Flexibility.

Aerobic component

Walking is an ideal exercise during pregnancy. It is low impact and chances of injury are minimal. The cycle, elliptic/cross trainer or stepper are all available in most gyms and can be used as alternatives for a low impact cardio workout. Twenty to 30 minutes of a cardio workout five days a week is ideal.

In the early stages of pregnancy, you may be just too exhausted, nauseous or ill-tempered to exercise. Slow walking, yoga, deep breathing with relaxation techniques are usually better alternatives to a vigorous cardio workout at this point. In the last trimester, it may be required to break up the workout into two separate sessions during the day to counter fatigue. Enthusiastic exercisers may be tempted to push themselves to the 70 per cent or even 80 per cent intensity that they are accustomed to. While this is ideal in the non-pregnant state, it is not recommended while pregnant. Stay at 50-60 per cent of your intensity (where you can have a comfortable conversation with your exercising partner, but not be able to burst into song) During pregnancy the centre of gravity of the body shifts due to the growing uterus. This, in addition to the instability of the joints of the feet and knees and hips can lead to a compromised balance and a higher risk of strains and sprains.

Higher work load on the heart during pregnancy (in the form of higher cardiac output and stroke volume) can cause higher intensity workouts to be detrimental to pregnancy. Staying at 50-60 per cent intensity is sufficient to sustain cardiovascular endurance.

The objective of aerobic training in pregnancy is not weight loss but optimum health. It has been shown to prevent and control gestational diabetes, improve mood, prevent oedema, help you sleep better, regulate bowel and generally make your pregnant months easier to deal with.

Strength Training and flexibility

Pregnancy brings about muscle imbalances and undue stress on certain parts of the body due to the enlarging uterus and weight of the breasts. Increased lumbar Lordosis (curvature) causing the pelvis to tilt. The shoulders round forward and droop. The wide paced, rather awkward, walk adopted in the later months, swollen feet, indigestion, backache, sleeplessness and fatigue can make these months hard to endure, leave alone exercise.

If the proper exercises to strengthen the over stretched muscles of the upper back (the trapezius, Latissmus dorsi, and Posterior deltoids) and stretch the tightened muscles of the chest (pectoralis and serratus anterior) and anterior deltoids are executed, a large part of the pain and discomfort can be relieved. Strengthening the legs, back and abdomen, stretching the inner thigh and hamstrings, exercising the pelvic floor muscles and working the calves will go along way in aiding the support of the extra weight in pregnancy without developing varicose veins and cramping. Relief for the stretched round ligaments by ‘hip flexion’ exercises or the tense pyriformis muscle by the deep gluteal stretch will relieve most of the common ‘aches and pains’ of the pregnant months. An easier and quicker labour has been found to prevail in women who exercise regularly. They are stronger, capable of withstanding pregnancy and labour and also recover at an incredible pace after the delivery.

Strength training exercises can be done in 15-20 minutes twice or thrice a week as time permits. There are several simple exercises which can be easily learnt.

Stretching

Stretching tightened muscles is imperative if you want to avoid the pain associated with the progressing pregnancy. It can be done everyday after warming up the muscles. Stretching the contracted muscles eases the tension and allows for a feeling of relaxation and calm especially when combined with the appropriate breathing.

A stretch routine can be used as a sole mode of exercise, especially towards the last few weeks, when any other activity seems intolerable. The synchronised breathing allows for some introspection and calm at a time when it may be impossible to do anything else.

Learning how to breath rhythmically during delivery, (although sometimes not a totally feasible exercise), can help you gain a sense of control of a situation that seems so hysterical.

Finally, exercise in pregnancy is not just about ‘staying in shape’ (as that is hardly possible!), but about staying in some semblance of control at a demanding time, finding tranquillity and inner strength, and about preparation for the foremost challenge of your life.

Diet and nutrition and emotional wellness during pregnancy and after call for another commentary at another time.

A few exercises that are specifically designed to combat muscle imbalances:

  1. Lateral raise/Shoulder press.
  2. Bent over lat raise/Seated Cable rowing.
  3. Flyes/Pushups, depending on the stage of pregnancy, followed by chest stretches.
  4. Hip extensions
  5. Quadreped Arm/Leg reach to stabilide the ‘core’.
  6. Abdominal crunches and Side Plank on the Swiss ball.
  7. Squats, lunges and calf raises to strengthen the lower body.
  8. Kegels exercises and pelvic Bridging for the pelvic floor muscles.
  9. Seated Cobbler, Spinal twists, Downward dog and Child’s pose are some of the yoga poses that can be incorporated into your routine.

Precautions to take while exercising: (ACOG Guidelines)

  1. Exercise in a cool environment to avoid over heating of the body. Warm up and cool down adequately before and after exercise and stay well hydrated.
  2. Avoid exercises that call for lying on the back for prolonged periods of time after the fourth month of pregnancy. Strengthening the abdominal wall can be done on the “Swiss ball” however.
  3. Always use the appropriate clothing and foot wear that allow for sweat to be absorbed and stability while moving.
  4. Avoid exercises that call for significant test of balance like the one legged poses of Yoga, running/skiing downhill and martial arts based exercises. The hormone Relaxin and Progesterone released in pregnancy lead to a certain degree of instability in the joints which present as loss of balance. It is not advisable to test this balance inordinately and incur accidents.
  5. Avoid high-impact exercises or contact sports, like horseback riding and high impact aerobics, tennis, kickboxing during pregnancy; the early months allow for a runner to continue running if that is your preferred mode of exercise, but as pregnancy advances it may be wise to change to a lower impact activity like walking. (Although I must admit, Indian women don’t need to be convinced of this, as they are already extremely cautious about any activity in pregnancy).
  6. At the first sign of any untoward symptoms like cramping, bleeding, loss of fetal movements, fall or injury, consult your physician.
  7. There are some relative contraindications to exercise in pregnancy like pregnancy induced hypertension, a low lying placenta, bleeding in pregnancy etc which your obstetrician should be able to warn you about.

How to Spend Money Wisely

Posted by cls On May - 2 - 2009

Spend money wisely and your wallet will never be empty. Follow these useful tips to be happy.

  1. Find clothes on sale. Look for clearance sales at stores. Try stores like DD’s discounts (they have awesome jeans for Rs.100 if you search hard enough). You can go through the mall and often bump into Rs.150 tank tops, Rs.250 jeans, and buy one, get one free events. Be sure to buy basic items like a long tank top, a basic t shirt, and at least 2 pairs of jeans.
  2. Find versatile footwear. Buy a pair of flip flops (black or white because they match with everything) .
  3. Avoid splurging too much at once. If you go out to the movies, for example, don’t buy movie theatre snacks. Instead, after the theatre, get a milkshake or doughnut from a store nearby.
  4. Accessorize. Accssories are costly sometimes but if you go to Claires and Icing on holidays, stuff will be 50% off. Get all your stuff during holidays. And if you wanna get really creative, make your own purses, bags, wallets, and cell phone and ipod cases by crocheting and knitting.
  5. Save half of each paycheck and use the other half for spending. Or divide it into three, some for spending, some for saving and some for bills.
  6. If your job does not take up all your time, get a part-time job to make more money. Even if this job is a once-a-week thing, if it means more money, go for it!
  7. Do not get a credit card unless you are under deadly circumstances. A credit card just tempts you to splurge out.
  8. Compile a list of what you need, and what you want. Budget for it so that when your salary comes in, you can buy what is on the list. Don’t buy anything that is not on the list, though. Include food, clothes, and extras for the kids.
  9. Treat yourself when you have saved a lot of money. Instead of buying that expensive watch, you bought a cheaper one and save and Celebrate by going out for coffee with a friend.
  10. Ask for a pay raise if you feel you deserve one. Tell your boss why you think you deserve one, and reason fairly.
  11. Know when to limit yourself. If you are a magazine obssessed person and you buy so many magazines each month, stop! Choose one or two of your favorite magazines and subscribe to them for a year.
  12. Don’t go out and spend all of your money at the pub, drinking. It is a waste. Limit yourself to a couple of drinks or no drinks per week. Or you can just quit drinking altogether. It will save you a lot of money
  13. Go through all of your old stuff, sort out a section that you don’t want and sell it. Hold a garage sale or auction off stuff on eBay. Instant cash!
  14. Avoid borrowing money. It adds up to the cost. You really want something. Put it on a list, and get it next month!
  15. Limit your computer, telephone, television, radio, and electricity time. Use candles instead of lights, watch less TV (if you are obsessed limit yourself to one TV show a day), don’t bother listening to the radio, go and visit your friends instead of calling them…..

What is Phishing?

Posted by cls On May - 2 - 2009

What is Phishing?

The practice of using fraudulent e-mails and copies of legitimate websites to extract financial data from computer users for criminal purposes is called Phishing

Phishing is an e-mail fraud method in which the perpetrator sends out legitimate-looking email in an attempt to gather personal and financial information from recipients. The messages appear to come from well known and trustworthy Web sites. Web sites that are frequently spoofed by phishers include PayPal, eBay, MSN, Yahoo, BestBuy, and America Online and many Banking sites. Like the fishing expedition it’s named Phishing and it is a speculative venture: the phisher puts the lure hoping to fool at least a few of the prey that encounter the bait.

Phishers use a number of different social engineering and e-mail spoofing ploys to try to trick their victims. In one fairly typical case before the Federal Trade Commission (FTC), a 17-year-old male sent out messages purporting to be from America Online that said there had been a billing problem with recipients’ AOL accounts. The perpetrator’s e-mail used AOL logos and contained legitimate links. If recipients clicked on the “AOL Billing Center” link, however, they were taken to a spoofed AOL Web page that asked for personal information, including credit card numbers, personal identification numbers (PINs), social security numbers, banking numbers, and passwords. This information was used for identity theft.

The users are advised to be suspicious of any official-looking e-mail message that asks for updates on personal or financial information and urges recipients to go directly to the organization’s Web site to find out whether the request is legitimate. If you suspect you have been phished, forward the e-mail to the original site from where the email is supposed to come from.
