Advantages Of Using Pressure Cookers For Cooking

In this contemporary era, time is of the essence for everybody and therefore 'slaving over the stove' is something that is almost extinct thanks to modern cooking devices. When it comes to energy efficient and time saving household cooking appliances, the pressure cooker definitely takes the cake. Owing to their versatile applicability pressure cookers are mandatory in every household nowadays.

Pressure cookers were invented in the year 1679 by a French physicist and even though this appliance has undergone a lot of changes for the better, the basic physical properties still remain the same. Another aspect which has remained unchanged is its objective - to render cooking easier, faster and more efficient.

The common misconception is that the pressure cooker can be used only in kitchens for the purpose of cooking. This is not so and it can also be used for reasons like conducting sterilization in labs and for boiling water high up in the mountains where it is almost impossible for people to do the same courtesy of the low temperatures.

A pressure cooker can be defined as a pot which has a tight seal to prevent the steam from escaping out. Therefore when the water inside the cooker boils, it will release steam and since the steam is not allowed to escape therefore it increases the pressure inside the pot, making it a lot easier and faster to cook the food. The steam inside pressure cookers would permeate through the food and soften it while at the same time preserving its nutrients, juices, texture and even flavor.

Ordinary open-pots are designed in such a way that the boiling point of water, i.e. 100 degrees Celsius has to be attained for the purpose of cooking food. But in case of regular pressure cookers, the food is cooked at a temperature of 121 degrees Celsius on an average with a pressure of 1kg per square centimeter or 15 lb per square inch.

Using pressure cookers in the kitchen can help save a lot of time, without compromising on the taste of the food being cooked. The time taken by ordinary cooking is almost double of the time taken by pressure cooking. Therefore it is not just economical but eco friendly as well. People swear by pressure cooking because it is said that the natural flavors of foods are evoked when they are cooked in a high-steam medium.

Although the normal boiling point of water is 212 degrees Fahrenheit, the same can reach up to 250 degrees Fahrenheit in a pressure cooker. This is because of the extremely tight-fitting lid which does not allow the steam to escape and this causes an increase in pressure within thus inducing the temperature to soar above the normal boiling point of water. Therefore a whole chicken which generally takes about an hour to cook in regular open-pot cooking will require only 15 minutes to be thoroughly cooked.

Since pressure cookers are mostly used in kitchens therefore they call for a lot of washing and cleaning. To facilitate this they are generally made from special metal alloy and other rust-proof components so that one does not have to deal with its corrosion and it is safe for cooking food at the same time. These cookers are a must-have for all health-conscious people because they steam-cook the food and retain the vitamins and essential nutrients, thus making the food healthier. Pressure cooker allows you to save time, money and energy as far as cooking is concerned.

Fitting and using a faucet water purifier is simpler than you think. These are the easiest to install and don't require you use any tools. If you mainly want to ensure you have clean drinking water in your home and don't want to spend money on a cartridge filtration system, a faucet water purifier will work very well.

All you have to do to fit them is unscrew the aerator on your sink's spout and attach the filter to it. Normally it screws on.

You will need to replace the filter cartridges in this type of filter regularly. Some find a faucet water purifier may slightly reduce the pressure of water, but this really isn't much of a bother for most people.

Be aware that a faucet water purifier unit will only eliminate particles and contaminants from the water in the sink that has the filter attached. Most people choose the kitchen sink as the ideal sink for a faucet water purifier as this is where one does the cooking, washes the food and where most people get their drinking water.

Some people like to have a separate filter for the bathrooms in the house where they wash their hands and brush their teeth. Fortunately, most water purifier versions are very economical, thus having one fitted at each sink is not much of a problem.

Pure drinking water is like an elixir and helps to keep us and our families healthy. Bear in mind, when you use a water purifier to filter the water running into and out of your home, you improve your body's health and well being.

A water filter that can be set up with no plumbing required. Who wouldn't like to cook and clean with purified water, water plants, fill fish tanks and give to pets and a cheaper alternative to buying bottled water?

It works through different stages of filtration and then diverting water through a diverter valve. It has a plastic or metal valve handle that is switched up or down to change to tap or filtered water.

A water purifier features a sub-micron high efficiency water purifier cartridge, providing an almost impenetrable, multi-stage defense against lead, cysts and various other chemicals common to municipal water supplies. Tap water enters the water filter cartridge within the Water Purifier and passes through three distinct micron-filtration barriers, providing maximum protection at every stage.

The average life span of a Replaceable Water Purifier Filter Cartridge is approximately 12-18 months, based on a family of four. The water purifier comes equipped with a unique electronic "smart" sensor, which measures the flow of water and visually alerts the user when to re-order a replacement water purifier cartridge and when to change the existing one. The battery operated electronic smart sensor and mostly has three blinking lights and they mean as:

Green - It means peak Water Purifier performance.

Yellow - Water Purifier performance is reduced and a new cartridge will be needed soon.

Red - Replace the Water Purifier cartridge before next use.

Remember, there are certainly many kinds of water and air purifiers available today, from ultraviolet water purifiers, distillation systems, reverse osmosis, etc. Reading reviews is probably the best way to find the top one for your home.

In addition to your regular home purifier, if you plan on being on the go often, you might consider purchasing a portable water purifier. This will give yourself pure clean water regardless of where you find yourself.

Automatic Rice Cooker

Rice is one of the staple foods around the world, and most countries will serve rice as the primary starch for a number of meals. Rice is a food that is fairly easy to cook, but it takes a good deal of time and practice to get it right. Without knowing the precise ratio of rice to water, you will find that your rice will come out either soggy, crunchy, or a particularly foul combination of both.

Using an automatic rice cooker is one of the best ways to ensure that your rice comes out perfectly. Thanks to the fact that the rice cooking process is fully automated, you are able to make the perfect rice. Each rice cooker has precise indicators of how much rice and how many cups of water you need to add to make the rice, so you don't need to worry about figuring everything out yourself. This will save you a good deal of stress, thanks to the fact that you no longer have to calculate precisely to try to get it right. Due to the markers in the rice steamer, you can simply follow the instructions to get perfect rice.

Another serious concern of many chefs preparing rice is the risk of burning the rice. If the bottom of the pot is not thick enough, the fire is too high, or there is not enough water, the rice runs a serious risk of burning. Few things taste worse than burnt, crunchy rice, but your automatic rice cooker completely eliminates the risk of the rice burning. You no longer need to worry about serving burnt rice, but you can simply put it on to cook completely confident that your rice will end up perfect.
Preparing the evening meal can be stressful, especially if you are a busy parent who comes home from work and has to whip up a meal in less than an hour. You may find yourself pulling out your hair as you run back and forth from stirring the meat to chopping the vegetables to checking the rice and back again. In order to reduce your levels of stress greatly, you will find that your rice steamer takes a huge load off. All you need to do is simply add the rice and water to the automatic rice cooker, turn it on, and let it cook on its own. You can even prepare the rice the night before or in the morning before you leave, as the rice cooker keeps the rice warm all day.

Most automatic rice cookers that you can buy will occupy only a small space in your kitchen, far less than a wide collection of pots in varying sizes will. Using a rice steamer in your home is the best way to ensure that you always serve the best rice, and you will find that a rice cooker is one of the best investments that you can make.

 


Open Source Software - The License Obligations

Since there are several hundred thousand free, widely used, and well maintained open source packages on the internet, it makes perfect sense to leverage open source whenever possible. If you are a commercial software developer that depends on selling your own software in the marketplace, however, it is important to understand the legal obligations and the legal restrictions that come with your open source license.

The courts have ruled that violating the license obligations in open source is similar to copyright infringement, ie, just because it is free does not mean you can ignore the license obligations.

With most open source licenses, obligations and restrictions in the license only apply if you distribute the open source, i.e., you distribute the binaries associated with the open source inside the binaries that you ship to your customers. If you use the open source software only as a development tool, the obligations posed by the open source typically do not apply.

With most Open Source licenses, the typical obligations center on attribution and re-distribution as well as various restrictions.

Attribution refers to giving credit to the authors and contributors of the open source software.

The requirements can include any of the following:

* do not remove copyrights present in the source code

* insure proper credit in the documentation

* do not imply that the open source authors endorse the commercial product without explicit permission

* clearly mark any modifications made to the open source

* if there is a redistribution requirement, clearly show in the documentation how to get the redistribution;

* in any advertising done for the commercial product, explicitly acknowledge the open source component provider.

Re-distribution refers to making the open source and related components free of charge and available to the public. This is typically done under the same license as the original open source and/or with a compatible license.

This can include the original open source, as well as any changes you make, and sometimes, any software "based on" the open source code. "Based on" is interpreted differently depending on the license.

Some licenses are designed to contaminate commercial software, being viral in nature. They can essentially force you to make all of your own commercial software that is linked to the open source software to also be given away free. These licenses are called "copy-left" licenses, and pose the greatest threat to a commercial software company's business model.

Common license restrictions can include:

* do not make any modifications to the open source

* do not distribute this open source software without adding value of your own with additional software

* do not remove license text or copyrights in the open source

* do not initiate patent claims against any of the contributors to the open source.

Violating these restrictions can cause the license to be terminated.

While there are many dozen unique licenses, the following discusses some of the common types:

The least restrictive licenses are public domain licenses. Source code provided in the Public Domain are free to use without restriction, i.e., you can use the source code without any attribution or redistribution and you can make modifications and derivative works; and you can distribute any or all of the open source software as you see fit.

These are followed by MIT style licenses, whose name comes from the license template which was created by MIT. In these licenses, the rights are similar to public domain with the only obligation being attribution. This attribution requirement is satisfied by leaving the original copyrights that came with the open source software in place and also providing credit to the open source authors in the end user documentation.

The next common style is the BSD style licenses, which was originally created by the University of Berkeley. The 2nd version of this licenses is similar to the MIT license, with the additional attribution requirement that the commercial software provider cannot use the names of the open source provider as a product endorsement without explicit permission.

The first version of the BSD license also required that in any advertising done for the commercial product, there was an acknowledgement of the open source provider; however, the 2nd version of the BSD license is far more common.

The next common license style is from Apache, which is a large cooperative of open source contributors, with an extensive library of open source software. The Apache 1.1 licenses requirements are very similar to the BSD 2.0 license requirements.

The Apache 2.0 license adds that any modifications to the open source code must be clearly marked with a change log. The Apache 2.0 license also adds an important restriction, the patent non-assert clause, which essentially states that if you initiate patent litigation against any of the authors or contributors who helped create this open source, you can no longer use the open source.

The next common set of licenses is the CPL or Common Public License along with its derivatives such as Eclipse, IBM, and Mozilla Public License. These licenses all have similar obligations to the MIT license, but they also have additional obligations in attribution and redistribution.

The CPL license requires that the commercial software developer has to make the original CPL licensed open source code as well as any changes to that source code made by the commercial developer, available for free. In addition, the commercial software developer has to state in the end user documentation how the user can obtain this open source code along with the changes. Finally, the source code changes made by the commercial developer should be clearly marked. It is important to understand, that nothing in the CPL or its derivatives compels the commercial software developer to give away for free its own code that is packaged in separate modules from the open source software.

The final common set of licenses are the LGPL v2.1 and the GPL 2.0 licenses, which together make up the majority of all of the open source code available on the internet.

The GPL 2.0 license has all the same attribution and re-distribution requirements as the CPL license above. However, the GPL also require any works based on those packages to be offered (re-distributed) under the same "free to the public" terms. Most commercial software companies consider this an unacceptable license for commercial software, because it does drive a change to their basic business model.

The LGPL v2.1 license carries a similar obligation to the GPL 2.0 license but has a more restrictive definition of where the re-distribution obligation applies, which makes it friendlier to commercial companies then the GPL license. For example, any commercial software which is not statically linked to the LGPL licensed package does not require re-distribution.

However, the LGPL license also carries other obligations such as requiring the distributor of any package which includes the LGPL libraries to allow the end user to replace those libraries. This can certainly cause support and packaging issues for the commercial software company.

There are also several dozen unique licenses for individual open source packages. While they can generally be classified as similar to one of the common licenses described above, they often have some unique requirement or feature that needs to be taken into account.

To summarize, open source licenses have requirements in attribution, redistribution, and they can have other requirements as well. Understanding the license obligations, and abiding by them, is the true cost of free open source. It is important to understand and manage these license obligations to avoid the risk of lawsuits and other legal issues.

Educational Software for Kids: How to Choose the Right Math Software

Regardless of your personal feelings on the subject of mathematics, you cannot escape the fact that many kids struggle in this area. Reasons for math woes range from true difficulties with numerical concepts to sheer boredom from kids who tend to learn in a narrative fashion.
Educational software for kids is a great way to help kids learn, apply and memorize math concepts. However, if you are not matching the program to the child, you may do nothing but increase math-related frustration. Here are a few tips on how to choose the right math educational computer software for kids.

If you need educational software to teach math concepts like arithmetic, division or algebra, the product you end up with will be different than if you are looking for something to help with memorizing basic multiplication tables. For example, a game that takes kids through a forest adventure where they battle monsters by solving multiplication facts is a fun way to practice times tables. For kids who do not understand math concepts or have not yet learned their tables, however, the game would only be frustrating. Those students need educational software for kids that presents the information in a lesson and practice mode before getting to a fast-moving game.

Many computer programs provide extra activities and games associated with math. Such programs are a great way to supplement traditional education and are different from computer curriculum. A curriculum program acts almost as a virtual teacher. These programs begin at a certain point, present math concepts in visual, audio and hands-on lessons. The software then tests for understanding through computer quizzes, games and questions. When using curriculum of this type in a home school environment, it is best to choose a program that integrates with a hardcopy workbook or other non-software elements.

Whether you are purchasing educational computer software for kids as a home school tool or a way to enforce math lessons learned in the classroom, it is important that the concepts being taught integrate well with other lessons. Software should teach math processes in keeping with the level of the student. For example, introducing algebraic concepts to a third grader working on basic division will cause confusion and may decrease his or her ability to apply math lessons.
Additionally, if computer software uses unusual methods to teach concepts, it may hinder the ability to process standard methods being taught in schools. Additional methods should only be introduced once children display a mastery over the concept in question.

By choosing math software that meets the needs of the individual child and education level, you can increase his or her ability to succeed with numbers. Introducing random or unvetted software can be detrimental to a student's understanding of math.
