Practical Use of Open Source Code Software

Practical Use of Open Source Code Software
As we started the project of our web site, we knew that the proprietary software costs would be too high for our financial resources. Our only option then was to make use of Open Source Code softwares.

However, within the Open Source Code there are lots of softwares to choose from, and it´s up to the system analyst/programmer to pick the ones that best suit the project goals.

In our case, we picked Linux as our operating system. However we faced a big question: Which Linux distribution ? There are dozens of linux distributions, each one with specific advantages, sometimes with or without paid services.

We chose linux Slackware because we thought that it would suit better our needs, in terms of stability and reliability. Slackware is a conservative distribution, meaning that it only offers in its distribution package kernel versions and third party libraries, once it´s been proved to be stable and reliable. As a result, Slackware is one the most stable Linux operating system on the market. If the user wishes the most recent Linux kernel and libraries, we recommend to look for a different distribution.

Another reason for us picking Slackware, was because of its text interface, which at the beginning may become a bit difficult, in the long run however it offers a better understanding of the Linux environment. This way most of Slackware configurations are done thru text scripts.

Once it was set the operating system, we picked Apache as our web server. Apache is one of the most popular web server in the internet. For server programming language, we chose PHP. Also, a very popular programming language. Our experience with Apache/PHP proves that this setup is very reliable, working extremely well in our production environment. For workstation programming language, we chose javascript, which besides of having a simple syntax, it offers lots of resources.

Apache web server is really a complete web server. Also, it can become very complex with many configuration setups.

For our database, we picked Postgresql. This database has been made available to the public for more than 15 years, and besides of being well debugged, it offers so many resources that it has become one of the best database options from Open Source Code softwares. Extremely reliable, Postgresql has reported cases where there have been databases in production with over 4 terabytes. Besides all of that, Postresql is not the most popular Open Source Code database. A matter of marketing ? Probably.

As for the programming language PHP, we had to use an object oriented application structure. There are many PHP application structures being offered with Open Source Code license. Object oriented application is very important, because it makes programming very easy and scalable up to the point where the system may grow without many problems. Also, it helps to keep PHP code separated from HTML, with the help of some specific libraries, such as Smarty. We make use of Smarty library and we believe that it is a very important resource, which can even make web pages faster thru the use of its cache functions.

Also a very important set of libraries worth mentioning for PHP systems, is the PEAR libraries. In PEAR web site, among the many libraries being offered, there are the database interface DB and the MAIL_QUEUE, which sends emails thru the use of database.

As we came to the end of our project, we had to use some sort of real time database replication. For that we chose the DRBD and Heartbeat libraries. The use of database replication is very important and should not be postponed. Just after 3 months our system got into production, our server hard disk became bad. Thru the use of DRBD/Heartbeat we were able to put the system back into production within seconds, without loosing any data. DRBD/Heartbeat replication is done thru the use of a lan network between the server and slave node

One of the biggest

One of the biggest and most important industries of today is the food and beverage industry. This is because this is what handles all of the foods and drinks that we find in the markets for us to buy and also the foods that we get in restaurants. This is why it is important for there to be lots of different pieces of technology, like a commercial food mixer, used in this industry so that it will always be in tip top condition.

There is a lot of gadgetry used in the kitchen nowadays, in order to make food preparation easier and better. There are machines that are made to chop, mix, cook, and do other tasks in the kitchen. These are very important, since they save a lot of time and effort, and not to mention money when it comes to making different food and beverages.

One of the most common types of food gadgetry is commercial food mixers. These mixers are made for processing food, and are often used in restaurants and places that require a lot of food to be processed and mixed on a regular basis. It is definitely a useful tool in any large kitchen.

By using this type of technology in the kitchen, you will be able to save a lot of manual labor and time. You won't have to have people processing, mixing, and blending the food, since you can have the machine do it instead. This will lighten workload on your employees, and allow you to save money on payroll as well.

Aside from saving time and effort, using a food mixer in the kitchen can also improve the quality of the food. You will consistently have well chopped and mixed food if you use the food mixer properly, and your food will not suffer from human error, so you can be sure you have delicious and well prepared food.

There are many different kinds of food mixing machines for different uses, so that different businesses and homes can choose the most convenient machine for them. Firstly, there are ribbon blenders, which are used for ingredients that do not require a long mixing time and require consistency.

There are vertical blenders which are used for dry ingredients so that they will be mixed properly and so that everything is distributed. Usually, this does not take a long time and this makes the blender efficient. For heavier mixing, free standing mixers are used. These are heavy duty and can work with tougher ingredients to mix.

There are many different uses for the commercial food mixer and different types available as well. You should choose the best type for what you plan to use it for. You can choose different types for just one kitchen, since you may need them for the different tasks you need to do to prepare food. This way, you will be able to utilize them to the best of their abilities, and you will have efficient and useful machines.
