JavaScript for Web Design – Advantages and Disadvantages

This article discusses the good and the bad points of using JavaScript in your website designs. It points out the areas where JavaScript excels as a web based programming language and also describes situations where its use can actually detract from the performance of a website.

First of all, JavaScript is a browser based programming language that actually runs client side. This means that any code that you write in JavaScript is delivered along with your web pages and the scripts that you write actually run from within the users’ browser rather than directly on the server that is serving the web page. There are situations where JavaScript is an excellent solution for implementing neat features in a web design but there are also situations where using JavaScript can hurt your websites performance. It is my aim in this article to describe the best ways to use JavaScript and how to circumnavigate the downsides of using this versatile and powerful scripting language.

JavaScript for Web Design – The Advantages

JavaScript is an excellent solution to implement when validating input forms on the client side. This means that if a user forgets to enter his name in a form for instance a JavaScript validation function can popup a message to let him know about the omission. This is a far better solution that having a server side validation routine handle the error because the server does not have to do any additional processing. An asp or php routine could be written to achieve the same task but the JavaScript would not allow the form to be submitted unless it was completed properly in the first place, a much more robust solution!

Another area where JavaScript excels is in the creation of dynamic effects such as rollover images and scripted slideshows, where its use has become commonplace. Because JavaScript runs inside the clients browser it can be used to change the appearance of the users screen after the page has been sent by the server. This allows it to create some very impressive dynamic image effects.

JavaScript for Web Design – The Disadvantages

One of the major draw backs to using JavaScript is that it tends to severely bloat web pages. JavaScript code can quickly add up to hundreds of lines of code if you are using it to do anything even remotely interesting. That said the problem of large chunks of JavaScript code is easily solved by storing the JavaScript code off into separate JavaScript source files that have a .js extension. This cleans up your web page code because the JavaScript code is stored separately to the HTML page itself, leaving a much cleaner and more readable web page.

Because of JavaScript’s tendency to bloat web pages it can be very detrimental to the search engine friendliness of your web site. This is because when a search engine arrives at your site looking for quality content and keywords to determine what your page is al about, the last thing it wants to see is hundreds of lines of JavaScript code. Again, this problem is easily solves by neatly storing JavaScript code away in script files with a .js extension and linking to the script file in your HTML documents.

Conclusion:

JavaScript is a feature rich and useful browser based script that if used properly can achieve some great effects and improve the experience for the end user. There are drawbacks to its use in that it tends to bloat web pages. The key thing to remember is to get the best of both worlds by using JavaScript code in external script files. That way the code is separated from your content so you get all the benefit of JavaScript functionality but without the adverse effects of the associated code bloating.

Everyday Tips for Weight Loss

Whether it is for wedding season, festive season or just to be healthy, everybody wants to lose weight and look fit. Unhealthy lifestyles often include a lot of junk and oily food along with very little or no exercise. Sitting in your work chair all day can cause all the fat’s to accumulate in the lower part of your body, thereby concentrating on your thighs and hips. Flab in the hips and thighs is basically known as cellulite. Cellulite is firm and can prove pretty difficult to get rid of. Here are some tips on how to reduce hip fat:

1. Drink Water

This solution looks like it won’t make a lot of difference, but it plays a significant role in controlling your weight. There is a reason why all health experts emphasize on its importance. Water purifies your system and releases unhealthy toxins off the body. It also boosts metabolism, thus increasing the pace of your weight loss journey. It’s recommended to consume at least 8-9 glasses every day for one to stay healthy. You can also squeeze some lemon juice in your water for added benefits.

2. Reduce Sugars

Limit your consumption of sugar in the form of chocolates & sweets. Sugar is a direct form of fat and the primary reason that causes flabby hips. Replace your sweet cravings with fruits instead. Soft drinks and aerated drinks are just as much loaded with huge amounts of unhealthy sugar. Chucking these out absolutely is an easy way to lose weight from your hip area.

3. Exercise

One of the most important tips to reduce weight is exercise. Regular workouts are necessary for trimming flab and controlling fat accumulation. Exercises that focus on maintaining the cellulite in your body are generally more intense and require more efforts. You should ideally workout for at least 30 minutes every day. Your daily workout must subsume exercises like squats, sit-ups, crunches, lunges and hip raises in variety of counts and orders. These exercises concentrate mainly on proper shaping of your hips and thighs. They are highly intensive and should be combined with cardio regularly. Also, you can fasten blood circulation and boost metabolism, effectively burning fats by brisk walking, jogging and running.

4. Control Calories

Stay away from junk and processed food like the plague! They have very little to no nutritional value and contribute absolutely nothing towards weight loss. They are the superfluous calories that slow down your path to healthy goals. Make sure that your meals always include green, leafy vegetables to improvise your nutritional intake. It must also contain proteins and vitamins in more quantities than carbohydrates and sugars. Prevent snacking as much as you can. Don’t eat all the time, instead, eat fulfilling meals so that you can keep frequent hunger at bay.

5. Yoga

Stress is usually known to be a cardinal factor in weight gain. Yoga & meditation help in calming your nerves & stabilizing heart rate. If you are running short of time to go through a yoga routine every day, the least you can do is ensure doing a breathing exercise for a few minutes in the morning. A relaxed body is definitely a healthy body.

Fitness is going to be a long journey full of a healthy diet and exercise routine. Constantly keeping a check on what you eat and maintain of a proper workout regime is the best way to maintain healthy and recommendable weight. Hips may be a tough area to trim, but with the correct mindset, dedication & determination, a slimmer waist is all yours. So plan your fitness journey accordingly and go ahead to that wedding function or vacation with a fitter version of you!

Photography For Beginners – Make Your Subject Really Stand Out

Great photography subjects are all around us. You do not have to go far to find interesting people, flowers, or wildlife. The real test is to use your skills to create a photo with genuine impact.

How do you make your subject really stand out in a photograph? It is tempting, but quite wrong, to blame the camera when your photo does not work out the way you want. You need to know right now that a more expensive camera will not automatically make you a better photographer. In truth, the techniques in this article will work for almost any camera. All you need are manual aperture and shutter speed settings, and a decent zoom lens.

Here are a few simple tips for adding impact to your subject.

Tip # 1. Highlight A Brightly Lit Subject Against A Dark Background. If you are shooting a subject in full sunlight, with a shady background, the subject is always going to stand out. This is a simple principle to understand, but it is a little easier said than done.

When your photograph has two very different levels of light, the lightmeter in your camera can be confused. It may expose for the dark background, causing your subject to be overexposed. The trick is to expose for the subject.

You can not do this on automatic. What you need to do is switch your camera to manual, and adjust the aperture and / or shutter speed settings until the photo is underexposed by one or two stops (depending on the lightmeter). When you get the balance right, you should have a dark background and a perfectly exposed subject.

Tip # 2. Use A Small Depth Of Field To Blur The Background. You have seen plenty of photos where the subject is sharp and clear, but the rest of the picture is completely out of focus. You will find this an easy way to add impact to the subject, and a three-dimensional effect to your whole photo.

To achieve this, you use a combination of a large lens and a wide aperture. First, zoom in on the subject with your largest magnification. This will naturally reduce the depth of field. Then adjust the aperture to its widest setting. A wide aperture will reduce the depth of field even further.

The closer you are to the subject the more pronounced the effect becomes.

Tip # 3. Use A Wide Angle Lens To Exaggerate Perspective. This technique is almost the opposite of Tip # 2. A wide angle lens makes everything in your photo appear much smaller, so objects in the distance seem much further away than they really are. Meanwhile, you can stand very close to a subject in the foreground (a person, animal etc) and still fit it in the frame.

As a result, your close-up subject will appear to tower over a background in which everything else looks very small and distant. Although the surroundings will be mostly in focus (the wide angle lens has a much larger depth of field), they will seem reliably small and insignificant, making your subject seem larger and more dominant by comparison.

So there you have three fairly simple ways to add impact to the subject in your photos. Because my background is in nature, I usually think in terms of wildlife, but you can probably think of many subjects that will benefit from these techniques.

The great thing is, you do not need a professional camera to try these ideas out. As I said earlier, if you have a zoom lens, and manual control of your aperture and shutter speed, you can add impact to your photos with just a little practice.

Even better, in the age of digital photography, practice costs nothing … so get out there and start snapping!

How to Prepare for a Family Photoshoot Outdoors

Once you have sat down with your favorite photographer and decided on an outdoor photowalk for your family photographs, there are a few preparations you can make to ensure that the day goes as smoothly as possible and that the resulting photos will be ones you will treasure for many years to come.

Choosing the location can be one of the most important aspects for a successful photowalk. Your professional photographer may well have some suggestions and ideas that you might want to consider, as he will have experience in finding beautiful outdoor backdrops. But even more important than a beautiful background, is choosing a place that has some significance or meaning to your family. It is all well and good finding a beautiful lake surrounded by trees to look pretty behind you in your photographs, but if the place has no importance to your family it will be simply a backdrop, and forgettable. A good photographer will be more than willing to let you lead when it comes to choosing the location for your shoot, such as your local park, your favorite picnic area, that spot on the beach your family goes to time and again, even the field where you and your family walk the dog – and feel free to include the dog, he is part of your family too! Your children, particularly if they are young, will find these familiar locations comfortable and will be relaxed and act as they normally do, allowing the photographer to capture those candid moments of play.

Towards that end, it is helpful to choose a location where there is something for your family to do, or items with which they may interact, such as the play structures at a park, or a path full of autumn leaves, or a sandy beach . Bring the toys and equipment you would normally bring for a day out with the family – the picnic blanket, or the shovel and bucket, or the Frisbee. Do not forget your child's favorite doll or blanket. All of these props can add to the candid, real-life look of your photos. In a familiar place, surrounded by their own things, your children will soon forget about the photographer, leaving him to truly capture the feeling and spirit of your loved ones. A picture of you and your family building a sand castle together on your favorite strip of beach, professionally shot and edited, will stay in your hearts and minds for a long time to come and will bring back memories of many days shared together.

Once the location and props have been settled on, it's time to think about clothes. Be yourself, be relaxed, let your outfit reflect that perfect location you chose. A fancy dress and a suit and tie at the family play park? Of course not. You want to look your best in your photos, naturally, but you also want to capture the true essence of your family. Put your children in shorts or a cotton dress for the beach, or snugly sweaters and wooly scarves for an autumn walk around the leaves. Try to coordinate, so everyone looks good together in the photos, without clashing colors or a lot of jarring, competitive prints. You do not have to dress in identical sweaters and jeans (unless you want to!), But make sure everyone's fits mesh together in a pleasant way, with similar or complimentary colors.

Whatever you wear and wherever you choose to have Your Photowalk , your professional photographer will capture a special moment in your family's history in ways that no casual snapshot or stiffly posed studio photograph ever could. These photos will hold pride of place on your wall or in family albums for many years to come.
