A Practical Use Of Open Source Code Softwares

As we started the project of our electronic auction, 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 web site 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 nodes.

Our project also makes use of ImageMagick (enlarge and reduce images), Iptables (firewall), Tsearch2(text search in portgresql) and Mon (linux monitoring tasks).

Also a very important library worth mentioning is the pseudo APC compiler for PHP. Speed is always a critical factor for internet sites.

Our web site is already in production and based upon our experience we can say that the Open Source Code softwares we picked, proved to be extremely reliable and stable. Open Source Code softwares can certainly be an excellent option for developing web sites.

A Nintendo Wii Bundle Is A One Stop Shop

By now you have certainly heard of the revolutionary new video game platform, the Nintendo Wii. Unlike anything that has come before it, the Wii makes the players part of the game with its revolutionary new control system. The Wii controller is a wireless remote control that senses movements in three dimensions. That remote sensing technology allows you to eschew the conventional buttons and joysticks that have been the standard for video games for decades. Instead, of pushing buttons or moving a stick, you move your arms; gesturing, swinging, poking, and sometimes flailing your way through the game! If you want to experience this amazing new game platform for yourself it can be difficult to know exactly what to purchase in order to have everything you need to enjoy the Wii experience. That is why the Nintendo Wii bundle is such an enticing option.

Purchased by itself, the Wii comes with a remote control – officially called a Wiimote – and a Nunchuk controller; an analog joystick that attaches to the Wiimote using a long cable. The Nunchuk also has the internal accelerometer that the Wiimote possesses, so it too is capable of motion sensing as well. The Nunchuk is to be used in conjunction with the Wiimote and it serves to enhance the game play experience. Further, the Wii includes all the power cords, audio-video cords, and the sensor bar and stands that you need to get started. Most important, the Wii includes Wii Sports, a game that lets you test your skills on the golf course, baseball diamond, bowling alley, boxing ring, and tennis court; it is the perfect platform to demonstrate the things the Wii can do. However, for those who want to see all the Wii is capable of doing, then you need more than the basic offerings, and a Nintendo Wii Bundle can deliver precisely that.

A Nintendo Wii Bundle is a package deal that is available at various retailers such as Gamestop, EB Games, and Wal-Mart. A typical Nintendo Wii Bundle includes all the basics that accompany a basic Wii purchase, but with many valuable extras. For example, the Nintendo Wii bundle available at Gamestop includes additional memory, an additional remote control, a twelve month product replacement plan, and 6 additional games; Legend of Zelda: Twilight Princess, Trauma Center: Second Opinion, Red Steel, Marvel Ultimate Alliance, Super Monkey Ball Banana Blitz, and Madden NFL 2007. The Nintendo Wii Bundle from Wal-Mart, and other retailers, follows a similar vein, but the included games can vary. For example, Wal-Mart offered four additional games in their Nintendo Wii bundle, and at a lower price that reflects the fewer included game titles.

A Nintendo Wii bundle is the perfect way to begin experiencing the fun and excitement the Wii has to offer. If you are purchasing a Wii as a gift for someone else and you are not a game savvy person, a Nintendo Wii bundle is a very attractive option because you can be certain that the recipient will not only have all the hardware they need to play, they will have a great selection of games as well. Depending on where you shop you might find that the Nintendo Wii bundle has been a hot seller and is currently not being offered. However, careful and thorough shopping will let you find a Nintendo Wii bundle deal that is available and with a selection of games that fits your needs and budget.

A New Generation Of Gaming And Psp Download

Gone are the days of spending hours sitting in front of the television as you robotically maneuver a joystick in an effort to control a little yellow circle; the primary goal of which was to devour each and every tiny dot meticulously positioned throughout a maze as it vacillated between running from or chasing after quickly moving ghosts.

Gone also are the days of carefully moving a cute green frog across a street as you carefully avoid any oncoming traffic; or the days where the hero of our game, on a quest to rescue the frightened heroine from the dreaded giant monster monkey, courageously jumped over barrels and oil tanks thrown by the game's evil villain.

In essence, gone are the simpler times in which we could be easily entertained by clear-cut video games. Instead, today's modern counterparts are multilayered, graphically intricate games that engage player in a way that could have once only been imagined.

Sony Computer Entertainment has created the PSP (PlayStation Portable System). The PSP System is a handheld, wireless, portable device that allows the users to not only play a number of high quality and multilevel video game products; it allows viewing of prerecorded and live television as well as videos and photos on a widescreen LCD (Liquid Crystal Display). The PSP System also handles playing music and provides connection to the Internet, as well as a wireless connection.

Although the system offers a multitude of uses, the main trait of the PSP system continues to be the gaming feature. Through the use of a PSP Download, users have the ability to successfully update the device as well as add a variety of content to their system.

PSP System users have the ability to choose a PSP Download through connection to the PlayStation website. A PSP Download can be easily integrated into the PSP system by connecting to the PlayStation website directly from the PSP device. Once access to the website is obtained, the user has the ability to obtain a PSP Download for a specific free game. Utilization of this portion of the PlayStation website also allows for downloading of software updates, game demos, game trailers, game audio tracks, wallpaper, and screenshots.

The PSP System has the ability to download more than one-hundred and thirty-five games. A Content Pack is available free through the PlayStation website. This pack includes pre-selected data that may be downloaded in one collection.

Movies and photos are also available for download on the PSP system. Through the utilization of a memory stick, this data can been downloaded and saved to the PSP system for use at any time.

Gone are the days of feeling the overwhelming satisfaction of clearing a full level of those little yellow dots, watching your four legged green friend hop safely to the other side of the street, or helping the hero reach his heroin after conquering his giant monkey nemesis. Now, children and adults are able to utilize the PSP System and enjoy their personal choice in a PSP Download.

Avid gamers as well as entertainment buffs are able to obtain a new level of satisfaction as they explore newly enhanced products, videos, television, music, and games through their PSP system.

A Need To Compare Pdf Files

Usually in PDF, what you can see in the file is the entire look of the page resembling that of a scanned text document. You cannot copy or manipulate the text just like in a word document. In cases like these, conversion of the said file is necessary. Other programs allow you to do that. In addition, another separate program can actually let you compare the PDF files from the original text or the other way around.

Imagine comparing a six hundred-page PDF document to its original form, would you think it would be accurate by just looking at these two files side by side and checking them per page? That would be a bunch of rapid eye movements and perhaps some points of missing out on some details. Most school projects like thesis, dissertations and term papers are now being accepted in a PDF file format. These are not only ten pages or so. It would take your precious time in checking for the details from the original text.

For a faster, easier and accurate way of file comparison, there are available versions of comparing programs for different type of files. A number of comparison possibilities are offered by the program. Comparing PDF file with another PDF file using the keywords would give you ease if you are so keen about details. You would not notice the similarity or the difference of two pages unless you compare their keywords. For busy and much occupied people, there is not much time in reading both of the article files just to compare them. The program itself will do this for you and it will analyze the article according to what kind of comparison you would want.

Aside from keywords, compare PDF files character by character is also possible as well as word-by-word. These functions are of big help when you are managing your files in your computer. Some of the comparison programs are capable of comparing folders too not only files. Your hard disk might contain many folders with subfolders and sub files. The program makes it possible for the browsing and comparing for similar files within the search range you have specified.

Comparing PDF files is very user-friendly. You can learn the process in less than an hour and you can compare PDF files as often as you want. Upon downloading the program, a step-by-step guide is provided and different options of comparisons are easily manipulated. And of the course, the program will also see to it that the changes you've made and comparison history are recorded. The previously compared files are retained for future references.

This is really a big help if you are creating PDF files and using them in your presentations or making a portable copy of a document with hundreds of pages. You can easily see if the file is exactly the same as the original document or duplicated in content. Different applications for comparing PDF files are obtainable in some internet sites. They are downloadable for a free trial. A lot of time will be saved and the quality of the file is maintained by using the application to compare PDF files.

A Look At The History Of Notebook Computers

A notebook computer is a term used interchangeably with laptop computers. For those of you not familiar, a notebook computer is one that is smaller and lighter than a personal computer. You can take it with you anywhere so it offers you more access to the internet, a way to watch movies, and even a way to work while you are away on business trips.

The first notebook computer was introduced in 1981 but they were very expensive and not as versatile as they are today. IBM and Epsom both placed versions of portable laptops on the market in 1983. Even with more models emerging, notebook computers were an item often associated only with high profile businessmen.

It wasn't until 1995 when Microsoft introduced their operating system Windows 95 that the world of notebook computers exploded. This operating system along with advances in technology that allowed notebook computers to function in the same ways as a personal computer led to them dropping in price and more consumers buying them.

Some of the improvements that occurred around this time were a better battery that no longer included acid. Power saving notebook computers were introduced so the life of the battery lasted much longer. They also were now able to hold more data so they could be used for more concepts at any given time.

Today you see people of all ages carrying their notebook computers to the office, home, on airplanes, colleges, and hotels. Many public places are set up with areas for individuals to conveniently use their laptops. Since we live in such a computer age having a notebook computer can help you stay on top of things for work and pleasure no matter where you go.

You can find notebook computers in a variety of sizes and from multiple manufacturers. They come with a good price, plenty of storage capacity, and warranties. If you are in the market for a notebook computer you will have no trouble finding exactly what you are looking for.

A Look At Information Technology Security For 2007

The world of computer security is a fascinating aspect and 2007 is not going to be any different, but it will be more interesting with the release of Microsoft Vista.

Large companies are looking to tighten the noose around those bad hackers, consumers are demanding more security and more privacy for there home computers, and who wouldn’t, credit card fraud and identity theft has not decreased it has only increased.

Hackers who like to hack into bank accounts are going to have a harder time doing that. Some online banking companies are asking there customers to take a further step in the login process when logging into there bank accounts. For example, some banks are asking there customers to enter their user ID on one page and then enter their password on the next page; this makes it more difficult for hackers. But don’t ever feel like you are safe, keep your guard up and don’t fall for any phony emails that ask you to go to a fake look a like bank website and enter your user name and password. If you do get one of those fake emails call your bank first, and ask them if they sent you the email, and you can also forward the email to the banks technical support team.

Thanks to companies like Webroot there are programs that can help you keep your computer secure and free of spy ware and ad ware, with their Spy Sweeper software which I highly recommend. Webroot also offers a great firewall that your computer should not be without. Go to AME Computers Spyware and Malware page for more information on these great products.

Another good move toward security and spam is that there are some ISP’s that are offering free spam filters, this helps cut down on the amount of junk mail reaching your inbox. The newer version of Outlook has built in junk mail filter, but what’s the point in having a filter if you have to go and filter through the spam filter that Outlook provides.

The flip side to all of this is the cost to consumers. Spyware and viruses can cost companies, and the average consumer thousands of dollars a year. Companies implementing new security hardware pass on those expenses to there customers, so it is not good for the consumer or the business. Microsoft Vista operating system has some built in features to help keep you safe; however there still may be a need for third party software to protect against spyware and viruses.

It’s a never ending battle between the good guys like Webroot and Lava Soft and the bad guys like the hackers and spammers. Do your part and fight the good fight.

A Hobbyist Device That Could Claim A Fortune

Metal detectors of all types may be termed as device for hobbyists either in land (parks, beaches, shores, and even in ballpark bleachers), or deep-sea waters. Seldom would hunters of all kinds set to track on land, or to ferry on sea without this device.

These hobbyists or adventurers may find it very beneficial not in terms of using this device to really get expected hunt like the archeologists and the sea fearer underwater hunters and pirates, but it provides a lot of enjoyment and exercise attainable at any rate just like in athletic gymnasiums.

Viewing from the immediate past, the misconception of metal detector is that of a very bulky backpack that is shoulder breaking, conceptualized in relation to the heavy adventurous perk of one who goes out for great land or sea adventures. Today, the modern innovation of such device devaluated that bulky heavy concept for metal detectors are sleek, lightweight rig, easy to use and handy that won't make someone tire until he spots his pot of gold.

The Underwater Metal Detector

Considered a best companion for sea fearers, sea sports enthusiasts, and fishermen, this underwater device serves best beside a batch of other equipment to any hunter at sea. A deep ocean adventure is incomplete without this piece of metal device, and it is very valuable at all cost. To a skilled scuba diver, having it is a must before his plunge into the deep waters.

Manufacturers who have reached high levels of expertise in metal detector design, and perfected pulse discovery techniques over the years paved ways to cope with today's innovation of the underwater metal searcher. Both amateur and professional divers could avail alike for easy use, handling, reliability, and practicability.

One of the best, if not, the best in metal detector today; the Elsec Metal Detector 2000 manufactured of tough non-corrosive construction for heavy-duty, using PVC ultimate High-Pressure moldings.

High-level sensitivity competes with other metal detectors with usage of the pulse inductive detection techniques on either ferrous or non-ferrous, and iron of divalent nature, and extensive distances.

With usability in approximate depth of 200 meters, it is neutrally buoyant, and controllable. To add it all in convenience, is the "no switch on and off" of power, for it automatically does so on both; upon immersion and up, from underwater.

A solid-state indicator alerts awareness how long will the battery last, but this model is furnished with rechargeable batteries that will automatically let power last for 10 hours.

A Handy GPS System

Today’s modern society means ownership of a bevy of gadgets guaranteed to elevate us to new levels of convenience. What would we do with our cell phones, PDA’s, and Blackberry’s? And now, there’s another handy gadget that sits in our palm; it may be small but it harnesses an enormous amount of power and brings it streaming right to our hands. The Global Positioning System – or GPS system - is the newest of modern gadgets that promises to keep us on the cutting edge of technology.

The GPS system uses the positioning of 24 satellites that circle the earth to pinpoint any location in the world. Having been developed by the United States Department of Defense, the GPS system was initially intended for military use when the first operational satellite was launched in 1978. However, by the mid-90’s, 23 more satellites had been added to the rotation and the modern GPS system was born. Today’s civilian consumers have taken the system and elevated it to ever-growing popularity.

The GPS system of today includes a network of devices used for mapping, navigation, and tracking that has replaced the compass and paper road maps of yesteryear. Users operate their GPS system in a variety of ways – from the computer mapping device to the navigational system available in newer cars.

One part of the GPS system is the GPS receiver – a hand-held device that receives its information from government satellites. Using this information, the GPS receiver does a series of latitudinal and longitudinal calculations that can precisely pinpoint the user’s location. A small screen will literally mark the location of the user amidst a larger map that shows surrounding points of reference. This can be enormously beneficial in a number of situations including the use by outside enthusiasts who frequently camp and hike.

The GPS system that seems to be most in use today is the navigational unit found in modern vehicles. While some units are portable and can be transferred from one vehicle to another, there are others that are permanently mounted in newer cars as part of their standard features. This GPS system – when given a specific address – can navigate the driver to their destination including turns, landmarks, and distances of all portions of the trip.

Most importantly, the GPS system of today is one that provides you with the most convenience that is specific to your needs and frequency of use.

A Guide Tip Audiobook Formats

Audiobooks generally come in two formats: MP3 and WMA. Both of these formats will play on PCs and Macs and most portable players, like the iPod.

The book publisher chooses which format they want the title to be distributed in. When you purchase a downloadable title from an online store, you are usually taken to a special area of the site where you can choose from a variety of file format based on the quality of the recording.

Naturally, the higher the quality, the bigger the file and thus the longer it will take to download. If you have a high speed broadband Internet connection you will probably prefer to download the highest quality file available. If you have a slow Internet connection you can choose to download a file that is smaller in size, but will not be of quite the same quality, but it will still be very listenable.

With 70% of the digital player market dominated by Apple and the iPod, a natural question is whether the audiobooks can be transferred to the iPod. The answer is a resounding "yes."

All you have to do is burn the files to CD first (this is a step we'd always recommend as it is wise to make a physical backup copy of anything you buy just in case your computer ever fails or is stolen) and then rip that CD straight into iTunes, when it's transferred to your iPod on synchronization.

And don't worry, Copying the files to an audio CD on your computer is quick and easy, particularly if you are using Windows.

It is very easy to download an audiobook. Once you have made your purchase from a reputable online store, you will be taken through to a special part of the site where you can download the files you have purchased. Easy to follow instructions are always provided on the download page.

Audiobooks will work on a standard PC and Mac and there is no risk of breaking the law as with many music sites and piracy.

ALL of the content of audiobooks has been approved by the publishers and copyright holders. As a paying customer you are
entitled to download and listen to these files as often as you wish and on whatever equipment you wish. However, like any other media, it is illegal to make copies of the files and give them to other people.

The length of time it will take for an audiobook download will vary greatly depending on what kind of Internet connection you have. If you have a broadband connection it will take just a few minutes per part. If you have a 56k dial-up connection it will be considerably slower.

If a recording is several hours long we will have split it into several parts to make it easier to download so even if
you are on a slow connection you can start listening to the first part whilst the others are downloading.

4 - Memory Storage: Digital photographs are stored in the camera`s memory. Most cameras have built in memory, but it will accept memory card as well, to increase its storage capability. Depending upon the picture resolution, a user can take hundreds of shots, before it exceeds the memory storage.

5 - Image Resolution: Also known as pixel resolution, this is one of the most talked about features in digital cameras. Although 2.0 mega pixels will deliver good photos for any personal and emailing purposes, nowadays digital cameras with 8.0 and above mega pixels (million of pixels) have become a standard feature. The higher the mega pixel resolution, the better it will look the pictures in larger prints. For those thinking about image enlargement, high mega pixel resolution is a must.

6 - Lens: Beware that the zoom feature may be of two kinds: optical and digital. Optical zoom relies on the lens magnification and delivers a good, sharp and clear image. On the other hand, digital zoom is the magnifying of the digital image and produces a less sharp, grainy image. So make sure that the digital camera offers some optical zoom capability. Also look for lens auto focus and image stabilization features.

7 - LCD: LCD screen is a standard feature in every digital camera, and it works for framing the shot beforehand and viewing it afterwards. Look for LCD screen size 2 inches and above for better clear images.

These new age voice recorders come as a handy solution for the busy business people who need to record notes, meetings, and ideas that can create a fuss if a tape would be used, instead of the voice recorder. A digital recorder is not all about recording voice, but it also has the capability to record and transfer information to your computer, making it easier to organize, edit and play back your voice files wherever you want.

With the increasing popularity of the digital recorders, there are many leaders in the electronics industry like Sony, Panasonic, Samsung, LG that provide the best voice recorders with the digital technology. But while buying a digital voice recorder, there are a few aspects involved in the selection of the best that you need to understand beforehand. So lets understand what a digital voice recorder is all about.

Look for the recording time.

Many voice recorders boast of the recording time by claiming the higher side of it. The recording time depends on the quality of recording and the higher the audio quality the lower the recording time would be. So rather than looking for a recorder that claims 300 Hrs of recording, look for the real picture of the recording time it can give with the highest quality.

Look for more storage options

Apart from voice files many digital recorders can store files, documents and images. These are equipped with the USB mass support class that helps them to store these files. Now with the storage comes the organizer, which is also an important feature to look for. Be sure that the digital recorder will store voice files in a minimum of three separate folders.

Look for voice recording features

The best of the voice recorders also exhibit many ‘smart' features that help you with the operations. Some of the interesting features you can find in the latest digital recorders are voice activation, which stops recording automatically whenever there is a long pause, or the cue/review feature that make it easier for you to find a particular recording part you want to play back.

It can also have a LCD screen for better operations. Some of the latest voice recorders also include software, which helps in converting the audio in a text file helping you with the transcription.

Look for connectivity

Like any other latest gadget the digital recorders are equipped with USB interface for PC connectivity. It helps a lot in transfer of files from the recorder to PC and vice versa.

A Few Tips On How To Pick A Web Hosting Company

As any good web developer knows, a web developer is always worried about creating the best web site that they can. They work very hard with the client to decide exactly how they want their site to look, to function, and also how to make it run the most efficiently. These are all things that people need to think about when they are creating a web site, but sometimes we forget one of the most important things, how are we going to get our site on the internet?

No matter how great the web site you create is, it is meaningless if you do not get it out on the internet. So if you are going to get our web site on the internet, then you can either host it on a web server yourself, or get a web hosting company to host it for you. If you are a large company that has an IT staff to setup the infrastructure to host a web site, then this is probably the best idea, because you have more control over the things that happen.

However, most people that create web sites do not have the money or the time to setup such an infrastructure. These people will have to get a web hosting company to host their web site. Here are a few things to consider when you try to pick a web hosting company that is right for you:

Space – Some web hosting companies offer more space than others. If you are going to create a large web site, or you are looking to expand a lot in the near future, then the amount of space offered is very important.

Email Addresses – If your web site is going to give away email addresses, or you need extra email addresses for your users, then the amount of free email addresses that you are given might be very important.

Database Access – Some web hosting companies offer the ability to use a MySQL or SQL Server database to store information or authenticate against. This can be a very important fact to help make your web site more secure, or more dynamic.
