How To Edit Video

The most useful aspect of computer video editing is that you can weed out all the “junk video” that finds its way into everyone’s home movies. I don’t know about you, but I believe that 95% of home movies are incredibly boring … mostly because you have to sit through hours of inane film in order to get to the few minutes of interesting material. I’ve found that the audience attention span for my own “fantastic” home movies is very short … so I now try to keep all my own movies under 5 minutes long.
There are many kinds of “junk video” that you might want to remove from your home videos …

1. Zooming
   Overzealous use of the camcorder’s zoom function is the number one sign of a beginning videographer. Zooming tends to make your audience sea-sick and should only be used for framing shots (i.e. Zooming between recorded scenes). Fortunately, you can edit these zooms right out of your videos and only show the wide establishing shots followed by close-up shots.
   
    
2. Preparing to speak
   If you are filming a narrator or filming a family member, there’s always that couple of seconds where they say “Ok … is the camcorder running?” Now you can cut that part out and start right with your interview.
   
    
3. Stillness
   Good video needs motion … action … something happening. For example, if you are filming a birthday and it takes your small child two minutes to open his birthday present, consider cutting out the middle 1.5 minutes. Your audience wants to see the motion … your child’s delight at seeing the present, and the triumph of getting it open. Unless the child gets an exciting paper-cut, the rest of the video is unnecessary.

There are several ways to get rid of junk video, and a video editing program like Movie Maker 2 makes it easy.

1. "Manual capture” only the video that you actually want
   When you transfer digital video from a camcorder to your computer, Movie Maker gives you the option of “manually capturing” your video, letting you decide exactly what sections of your tape you want to transfer. This allows you to capture ONLY the parts of your video tape that you want in your finished move, thus saving you a lot of precious hard drive space. While Movie Maker gives you the option of capturing an entire video tape, I rarely do this because 75% of my video is “junk” that I never want to watch again.
   
    
2. Cutting clips in half
   Movie Maker allows you to “cut” your video clips in half. This is a great way to get rid of large chunks of “junk film.” You cut your clips in two different places within the program … both in the preview monitor, and also while working on the timeline. Simply find the location you want to cut and click the “cut button” located under the preview monitor.
   
   
   
   Cutting clips is great way for getting rid of large areas of video (or breaking up clips that you want to place at different places on your timeline). The only problem with cutting is that you must stay organized -- if you cut 30 separate video clips, you’ll end up with a whooping 60 video clips in your video collection and that can be hard to sort through.
   
    
3. Trimming the ends of clips
   For the finest control, you can trim the ends off your clips by setting the exact “in and out” points of each video clip. While working on the timeline, simply “drag the ends” of each clip to the exact point that you would like it to start and stop. You can accomplish very fine control of each clips start/stop points by trimming … especially if you zoom in on each clip using the magnifying glass.
    

As you can see, deleting unwanted film is very easy to accomplish within an editing program like Movie Maker 2. This gives you much more freedom when you actually film … as now it’s OK to film your kids’ entire 2 hour soccer game. You can always edit out the junk (those other pesky kids) using your computer. After all, film is cheap, and you never when you’re going to film that surprise goal!

How to Make a Resume

Want to make your résumé shine? Here's how to put together a résumé that will impress any prospective employer.

1

Understand the purpose of a resume. This will help you to identify what is really important to focus on when putting yours together. Basically, a résumé is a brief overview of your experience and credentials put together in such a way as to sell you as one of the best choices for a prospective employer to interview. It initiates the process of introducing yourself to the employer. Therefore, given that a résumé is both introductory and a personal sales presentation, a good résumé will be concise, easy to read, positive, and interesting.

• A résumé is not a mere summary of what you've done – a résumé needs to be focused on the job targeted, making the content relevant to the hiring team's viewpoint.^[1] An often-made mistake is to develop a "one-size-fits-all" résumé without tailoring it to the specifics of the job.^[2]
• Look at existing résumé examples to get a good feel for putting together a good résumé. Borrow books on résumé writing from the local library, or get online and check out résumés uploaded by various people. Within your industry, it's often possible to get a search return for people who have submitted résumés that have been made public and stored electronically, and this gives you a great opportunity to see how the top people in your industry prepare their résumés.
• Know what the reader will be looking to get out of a résumé. Key professional behaviors that a reader will want to see leap out from reading your resume include communication and listening skills, ability to be a team player, goal orientation, analytical skills, motivation and initiative, reliability and dedication, determination, confidence, pride and integrity, efficiency, and the ability to follow directions.^[3]

2

Make it easy to read. The manner of presentation will impact how easy it is to read the résumé. Use good taste when developing a résumé and forget gimmicks; in general, recruiters approach resumes conservatively and do not like or trust being presented with resumes printed on color paper, in 3D, with unusual fonts, or shaped like whatever product the company's trying to sell.^[4] Stay with what is tried and trusted because recruiters like the familiar, and anything that bucks that trend risks a negative reaction.

• Use the font size 10-12. For a traditional look, use the serif Times New Roman. Use Century Old Style for traditional business jobs. For a more contemporary look, use the sans serif fonts Helvetica or Arial. Non-traditional fonts not only risk looking unprofessional but if you're emailing them and your employer doesn't have the font type, your resume will end up unformatted as it's replaced by a different font, with the end result probably looking unreadable.^[5] You can avoid this problem by emailing the document as a PDF file.
• Avoid switching between too many fonts. Sans serif fonts are best for headers, serif fonts are best for listing the content details.
• Use bold and italics to make important information stand out but use bold sparingly. Also make use of white space; ensure there is enough to make it easier to read.
• Use black and white. Color should be used restrictively and preferably not at all.
• Keep the format neat and well organized. Format consistently throughout the document.
• If printing hard copies to send, use quality paper

Choose a style you'll use. Leaving out personal pronouns is commonplace but the use of third person or first person is really up to you and your personal style. What matters is that you come across as personable and someone people want to work with. Don't make it overly stiff or overly casual; try to find a perfect medium. Be careful to maintain the correct tense throughout the résumé.

How to Lose Weight Fast

Do you want to slim down fast for that beach vacation or high school reunion? While there are many things you can do to shed pounds, losing weight too quickly, like any sudden change to your body, can be dangerous. While fad diets, diet pills, and fasting may indeed induce rapid weight loss, these methods can cause you to get gallstones^[2], start losing muscle and hair and may also injure your heart and other organs fairly quickly. The best solution? Don't go for an overnight miracle. Instead, follow these steps to lose weight rapidly, healthily, and sustainably.

1 Have confidence in yourself. You should know the exact reason that stimulates you to reduce your weight. This will help keep you motivated in your weight loss program.

1. 2
   Set an achievable goal for your weight reduction. If the aim is not practical then you will easily get disheartened and stop following your regime. You must set a target that has a time limit. The amount of weight you want to lose and the time within which you would like to lose it should be decided beforehand. If the time and amount of weight is clearly decided primarily, your enthusiasm will keep you on the track until you reach your destination.
2. 3
   Determine your daily caloric intake. Losing weight is simply an activity. Lower your calories intake without starving. Remember to calculate your metabolism. The metabolism is a large part of your calories burned in an average day. To win the battle, know how many calories you consume in a day.
   • Write down all the things you eat on a typical day. Carry a small notebook with you and write down every snack, every drink, and the contents of every meal. There are also great websites that you can use to keep track of calories, get recipes, and help achieve your goal. Don't forget to include the pats of butter or the spoonful of sugar in your coffee. It's best to do this for at least a couple weekdays and a weekend; it's even better if you can go a full week. There are also calorie tracking websites that can help you to do this, such as the US government Pyramid Tracker website.
   • Do an itemized calorie count. When possible, write down the number of calories in each thing you eat as you eat it. Keep in mind that the recommended serving size is often considerably smaller than the serving you actually eat. Look up the calorie count on the internet for foods that don't have calories listed on the container or for fast food meals. You don't have to be 100% accurate, but you do want a good estimate of the number of calories you're taking in. There is an idea that multiplying your ideal weight by ten will produce a rough estimate of the number of calories you need to eat per day to maintain your weight. This is not true for everyone. You may wind up grossly under or over estimating the number of calories you should be eating. Consult a nutritionist. Use a scientific or health website to determine the number of calories you should eat a day or consult your doctor. Everyone has different metabolisms and there is no blanket rule that covers everyone's recommended calorie intake. Reducing 500 calories per day from the calories you eat to maintain your weight can help you lose a pound of fat per week. ^[3]
3. 4
   Go over the list and decide which foods to cut out or reduce. Cutting calories is usually a lot easier than you might think. For example, that daily tall latte in the morning may pack 500 calories. Since a pound of flab (lost or gained) is roughly equivalent to 3,500 calories, replacing that rich beverage with black coffee can help you lose a pound a week. Other easy cuts include salad dressing (salad dressing is the number one source of fat in the average American woman's diet^[4]), soda pop, candy, and butter. Look at the nutritional information for the foods you eat, pay special attention to your intake of saturated fats and empty calorie, high-sugar foods. You don't need to cut these things out entirely, but if you reduce your intake of high-fat, high-calorie foods you'll lose weight faster.
4. 5
   Seek out alternatives to the unhealthy foods you've identified. You can simply reduce the amount of soda you drink or mayonnaise you put on your sandwiches, or you can substitute healthier choices. Drink water instead of soda, for example, or use mustard instead of mayo. Low-fat and low-calorie options are also available for most foods, and many of these are natural, (although some may contain chemicals), and tasty. Start trying to eat healthy in most meals:
   • Choose lean meats. Chicken and fish are both very low in fat, and certain fish like salmon, sardines, and fresh tuna are an excellent sources of antioxidants and Omega-3 fatty acids, which are also beneficial to your health, so aim to replace some or all of the beef or pork in your diet with these foods.
   • Replace high-calorie side dishes with healthier alternatives. Many people get a ton of calories from side dishes such as macaroni and cheese, French fries, or potato salad. You can eat healthier and lose weight by replacing these with fresh vegetables and salads. Pre-made salads are practically effortless, and when accompanied by a reduced-calorie dressing or no dressing at all, they're weight-loss gold.
   • Start your days off right. A fattening breakfast of bacon and eggs or a pastry can be replaced with yogurt, oatmeal, high-fiber, low-sugar cereals; or fresh fruit for fruit smoothies. However, for those on a low carbohydrate diet bacon and eggs are a great combo for breakfast, since neither have carbs. But don't fall into the trap of skipping breakfast. Eating a healthy breakfast increases your rest metabolic rate earlier in the day, and reduces snacking before lunch.
5. 6
   Plan your meals. Look for healthy, delicious meals online or in your cookbooks, and create a menu for the week. Make sure that your meal plan reduces your total calorie intake: you're not going to lose weight if you consume the same amount of calories by eating different foods. Make a list of what you'll need for these meals, and -- except for a few snacks, of course -- don't stray from your list when you get to the market. Planning your meals helps ensure you get a balanced diet and reduces the temptation to stop off for fast food or order a pizza. Remember, it's easier to stick to your shopping list if you shop when you aren't hungry - this will help avoid impulse buys which contribute to calorie consumption.
6. 7
   Watch your portion sizes. Eating a whole bag of rice cakes in one sitting won't help you lose weight. When eating chips, nuts, or dried fruit, put a portion in a small bowl and then put the bag away. That way you won't mindlessly eat a larger portion than you had intended. Even if you only make minimal changes to your diet choices, reducing portion size will inevitably reduce caloric intake. A great way to watch portion sizes while snacking is to buy one serving 100 calorie packages - and they come in many favorite snack food items! Eat slowly to avoid overeating; you will get satisfied with less calories.
7. 8
   Graze on healthy snacks. Just because you're getting healthy doesn't mean you can't snack. In fact, eating small meals and snacks throughout the day, or grazing, has been shown to aid weight loss, compared to eating three large meals a day, by keeping metabolism steadier. Pick snacks that are low in calories and fat and high in fiber dried apricots, nuts, rice cakes, fruits, baby carrots, cherry tomatoes, and so on. Vegetables are generally very low in calories, very high in fiber, and full of flavor and nutrition. Avoid starchy vegetables like potatoes, and try to eat vegetables plain, without fatty dressings or dips. Fruit also makes a good snack. Fruit contains more soluble fiber than vegetables, which slows your body's absorption of carbohydrates, thus releasing energy more slowly preventing sugar highs, and keeping you feeling full longer. Fruit juices are not a replacement for the real thing. You need that fiber, and juices often have more calories than the equivalent serving of fruit and as many calories as soda! Be careful with dried fruits, because without the water, you tend to eat more, and fruits, when dried, are calorie-rich per ounce. With any dry or dried food, be sure to drink plenty of water.
8. 9
   Get more fiber. There are many myths about fiber, but there is science to back up its helpful role in the diet. Fiber keeps the right amount of water in your intestines, making your digestive system work more efficiently and helping to keep you regular. Thus, just eating enough fiber may help you feel slimmer in just a day or so. There is also evidence that fiber in the diet can help prevent stroke and heart disease, ease the effects of diabetes, and may even directly help in weight loss.
9. 10
   Drink plenty of water. An adequate amount of water is essential for health, and a great many people simply don't get enough. What's more, if you're chronically dehydrated, your body will retain water in unflattering places, so if you make sure to get plenty of fluids you can start visibly trimming down in as little as a day. Remember, the more you exercise, the more water you'll need. See the related wikiHow for more details on how much water you should be getting. Drink one glass of water before your meal; it will help digestion and also to get the sensation of fullness in your stomach that will keep you from overeating; that in combination with eating slowly, will allow you to stop eating when you are satisfied, not when you already ate too much (If you eat too fast you can get full, even bloated but still be hungry) .
10. 11
    Write down your targets on sticky note pads and then stick them in most spaces of your home. These stuck notes will always remind you of your goal and will further inspire you to stay on your regime. They would not let you forget your goals at any time.
11. 12
    Exercise. Remember, you can lose weight either by decreasing your calorie intake or increasing the number of calories you burn. Any health strategy should include both, but if you want to lose weight fast, exercise is essential. By making time for exercise and other healthy, productive activities, you can also avoid temptation to overeat.
    • Perform low impact aerobic activities. Moderate aerobic workouts incorporating brisk walking, cycling, aerobic machines, or swimming not only burn calories they also keep your heart healthy. Swimming is great, especially if you are quite overweight or have joint problems, because you can get the same benefits of running typically burning even more calories with much less stress on your joints. Try to get at least 30-40 minutes of aerobic exercise at least three or four days per week.
    • Pump some iron. Resistance training, weight training, can help both sexes stay lean by building muscle and raising metabolism. The fact is, hours and hours of aerobic exercise won't help most people lose weight fast because your metabolism drops back to normal fairly quickly after stopping the exercise. If you gain muscle, however, your body's resting metabolism, (the amount of calories you burn when you're just sitting still), increases, because muscle requires a lot of calories to maintain. Studies have shown consistent weight training to raise the body's metabolism by 15%. This means an average woman might burn 200-300 more calories at rest every day! Resistance training is the gift that keeps on giving!
    • It can be fun! Although you're losing weight through possibly painful exercises, it doesn't necessarily have to be a boring and painful procedure. If you want some extra motivation that will cover up the pain, get the video game Wii Fit. Built by Nintendo, this system helps you do exercises such as yoga, aerobics, strength training, and balance. If you want to work on burning calories, you can always run, but when you run on Wii Fit, it's twice as fun, because you always have a score to beat, and if you're competitive enough, it's a great way to burn the calories and get in shape.
12. 13
    Rest properly. This means not only taking at least 24-48 hours between strength training the same muscles, and taking 1-2 days off from exercising each week; it also means knowing how much sleep you need, since sleep deficiency impairs your ability to lose fat.
13. 14
    Be realistic. Don't expect a miracle. Healthy weight loss can be achieved fairly quickly, but you'll need to be patient. In addition, be sure to set realistic goals. Make sure that the weight you're trying to reach is a healthy weight for you, and keeping in mind that gaining pounds of muscle will help you lose fat, be trimmer, and look better even though you don't actually lose any weight. Your goal should be a healthy body, not a number of pounds! Everyone looks good at a different weight. A short person may look really good at about 112 pounds, but a person of a taller height would just look unhealthy. Keep yourself at a weight that makes you look good, not at a number that sounds good.
14. 15
    Make adjustments. A successful weight loss strategy based on reducing calorie intake and increasing activity can be adjusted to maintain your desired weight once you reach it. Unlike typical diets, this method is sustainable; it is a lifestyle change, not a binge-and-purge exercise. Slowly adjust your diet and exercise to include more weight training and calories, as much as is comfortable for you. If you do gain any weight back, you want that weight to be lean, toned muscle, not fat. In addition, weight training, no matter what your age, prevents muscle atrophy and can help stave off osteoporosis.
    • Instead of thinking of it as losing a certain amount of pounds, think of it as being a certain weight. So if you are 145 pounds, and you would like to lose 10 pounds, think of it as being 135 pounds. This helps you think about it as a long-term goal and not just losing the weight to gain it back again.
15. 16
    Be confident. You need to believe in yourself! If you want to diet, and you know that it will make you feel better, then you need confidence. Otherwise, the temptation to cheat on your diet will make it harder, and you will not feel better when you do lose weight. Avoid temptations like chocolate, ice cream, and cookies. They may taste good, but there are other foods that taste delicious, too, without being unhealthy. You need to always encourage yourself to achieve the goals that you have set. Learn to evaluate your efforts fairly and objectively. If you fail to achieve your target for the week, find out why is it so. Is it because you have missed an exercise session? Or you have been eating junk food for one of the days? After evaluating, look ahead to next week and try your best to stick to your plan.
16. 17
    Be consistent and disciplined, and have self motivation. To lose weight effectively, you need to stick to your weight loss plan religiously so as to see results. When you think about giving up, visualize the benefits of slimming down successfully.
17. 18
    After you achieve your targets successfully, you must maintain your weight loss. You must form a way of life that is healthy for you. Make certain that you don't gain back the weight you lost by returning to your old eating habits.
18. 19
    You can simplify weight loss with a pre-planned diet, many of which involve ready-made food. Be especially cautious of and do not spend long (more than, say, a month) on a diet which involves an extremely restricted variety of foods; do not use any that involves drugs without consulting a doctor. Some involve special versions of a variety of more-or-less ordinary food.
    • Preparing menus and queuing up portions of food well in advance can help you stick to a diet (by having a well-defined diet to which to stick) and avoid reminders to think about varieties of food daily, which is very helpful when trying to eat less of it. This can help you Easily Stick to and Enjoy a Diet Such As Nutrisystem or any other.

How To Using Elastic IP to Identify Internal Instances on Amazon EC2

 Using Elastic IP to Identify Internal Instances on Amazon EC2

 

Elastic IP

Amazon EC2 supports Elastic IP Addresses to implement the effect of having a static IP address for public servers running on EC2. You can point the Elastic IP at any of your EC2 instances, changing the active instance at any time, without changing the IP address seen by the public outside of EC2.
This is a valuable feature for things like web and email servers, especially if you need to replace a failing server or upgrade or downgrade the hardware capabilities of the server, but read on for an insiders’ secret way to use Elastic IP addresses for non-public servers.

Internal Servers

Not all servers should be publicly accessible. For example, you may have an internal EC2 instance which hosts your database server accessed by other application instances inside EC2. You want to architect your installation so that you can replace the database server (instance failure, resizing, etc) but you want to make it easy to get all your application servers to start using the new instance.
There are a number of design approaches which people have used to accomplish this, including:

1. Hard code the internal IP address into the applications and modify it whenever the internal server changes to a new instance (ugh and ouch).
2. Run your own DNS server (or use an external DNS service) and change the IP address of the internal hostname to the new internal IP address (extra work and potentially extra failover time waiting for DNS propagation).
3. Store the internal IP address in something like SimpleDB and change it when you want to point to a new EC2 instance (extra work and requires extra coding for clients to keep checking the SimpleDB mapping)

The following approach is the one I use and is the topic of the rest of this article:

4. Assign an Elastic IP to the internal instance and use the external Elastic IP DNS name. To switch servers, simply re-assign the Elastic IP to a new EC2 instance

This last option uses a little-known feature of the Elastic IP Address system as implemented by Amazon EC2:

When an EC2 instance queries the external DNS name of an Elastic IP, the EC2 DNS server returns the internal IP address of the instance to which the Elastic IP address is currently assigned.

You may need to read that a couple times to grasp the implications as it is non-obvious that an “external” name will return an “internal” address.

Setting Up

You can create an Elastic IP address in an number of ways including the EC2 Console or the EC2 API command line tools. For example:

$ ec2-allocate-address 
ADDRESS 75.101.137.243

The address returned at this point is the external Elastic IP address. You don’t want to use this external IP address directly for internal server access since you would be charged for network traffic.
The next step is to assign the Elastic IP address to an EC2 instance (which is going to be your internal server):

$ ec2-associate-address -i i-07612d6e 75.101.137.243
ADDRESS 75.101.137.243  i-07612d6e

Once the Elastic IP has been assigned to an instance, you can describe that instance to find the external DNS name (which will include the external Elastic IP address in it):

$ ec2-describe-instances i-07612d6e | egrep ^INSTANCE | cut -f4
ec2-75-101-137-243.compute-1.amazonaws.com

This is the permanent external DNS name for that Elastic IP address no matter how many times you change the instance to which it is assigned. If you query this DNS name from outside of EC2, it will resolve to the external IP address as shown above:

$ dig +short ec2-75-101-137-243.compute-1.amazonaws.com
75.101.137.243

However, if you query this DNS name from inside an EC2 instance, it will resolve to the internal IP address for the instance to which it is currently assigned:

$ dig +short ec2-75-101-137-243.compute-1.amazonaws.com
10.254.171.132

You can now use this external DNS name in your applications on EC2 instances to communicate with the server over the internal EC2 network and you won’t be charged for the network traffic as long as you’re in the same EC2 availability zone.

Changing Servers

If you ever need to move the service to a new EC2 instance, simply reassign the Elastic IP address to the new EC2 instance:

$ ec2-associate-address -i i-3b783452 75.101.137.243
ADDRESS 75.101.137.243  i-3b783452

and the original external DNS name will immediately resolve to the internal IP address of the new instance:

$ dig +short ec2-75-101-137-243.compute-1.amazonaws.com
10.254.171.132

Existing connections will fail and new connections to the external DNS name will automatically be opened on the new instance and

Using CNAME

It is not entirely intuitive to have your application use names like ec2-75-101-137-243.compute-1.amazonaws.com but you can make it clearer by creating a permanent entry in your DNS which points to that name with a CNAME alias. For example, using bind:

db.example.com.    CNAME    ec2-75-101-137-243.compute-1.amazonaws.com.

You can then use db.example.com to refer to the server internally and still not have to update your DNS when you change instances.
