What Is RSS?


RSS is technology - a simple software program - that allows you to access web and blog content automatically. The acronym's most popular translation is "Really Simple Syndication. Once your browser or computer has an RSS reader on board, you can subscribe to any number of RSS "feeds." A feed is simply a way in which a reader may subscribe to website content - most commonly blogs or news sites. A news site, for example, may list their latest headlines or entire articles in their feed every time a new article is published. A blog would publish this feed as a series of recent posts.

Feeds are published by millions of publishers, from small individuals to large organizations like Newsweek. The value of a feed is that it brings the most current site content to you in a format that is easily scanned; further, you are spared the task of visiting each source site each day. This is typically done through the use of what is called an 'aggregator' or 'feed reader'.

Feed readers or RSS readers, are software programs that run on your computer (or PDA or phone); let you easily subscribe to feeds, and allow you to read through them efficiently. Some are relatively simple, showing the headline and summary. The fancier ones often work with (or in) your browser to make viewing the material look much like the source page. Once you have a reader on your computer, subscribing to a feed with is an easy click or drag from your browser. Sites that provide RSS feeds will usually have a button for that purpose.

There are several RSS feed formats as well as one with an entirely different methodology called Atom. Atom has become popular with some bloggers and blogging tools. Some aggregators can read both. The other acronyms you will see in "feedspeak" are XML, which stands for 'extensible markup language' and is the code standard for these simple text feeds. An 'OPML" file is a format for indexing hierarchical feed lists. If you dive into this web habit in a big way, your aggregator or reader may keep your subscription list in an OPML file.

An RSS feed is a great method for staying abreast of issues and topics that interest you. There are a number of feed "libraries," so to speak, from which you can learn what's out there in your areas of interest. Google has a built-in reader that makes the subscription process easy, as does Yahoo. Firefox has a downloadable extension for the purpose of aggregating RSS feeds, as well as a default ability to save RSS feeds as "live bookmarks" that update via the RSS feed. You can download a number of stand alone readers and aggregators; you can find them through a simple web search.

The whole RSS "movement" is a step towards utilizing the Internet more efficiently. The trick is to avoid overloading your email inbox with daily reports that you end up ignoring most of the time. For that purpose, there are sites like Feedster that will search millions of RSS feeds for articles that are relevant to your interests. Like any search tool, however, these services are hit and miss. They are still working off keywords and sometimes what they find is relevant, sometimes not. But if you want daily news broken into categories, it's great technology once you learn how to make it work for you.

Fix Computer Problems In A Jiffy With Rollback Rx


Rollback Rx system restore software is mandatory for every computer user to ensure system security and data loss prevention. More so in educational institutions dependent on PCs for their routine work, where a rollback tool is essential since most are multi user systems. PC restore is a regular operation that has to be done, to preserve data and to repair computer problems that might arise from misuse of computers. This can happen in many ways, but can be totally avoided with a disaster recovery solution like Rollback Rx.

Areas Where Rollback Rx Can Repair Computer Issues

In colleges and universities where several people use the same computer, students store their academic work in the form of reports, software programs, etc in various folders. Because many people use the same system, the necessity to fix computer problems arises when certain files or folders become deleted or moved. This could very well cause problems. With Rollback Rx, PC restore can be done easily to a secure state, to keep the operating system and other data intact.

Unauthorized Downloads Can Be Fixed With Rollback Rx

There is a tendency to download free programs that appear useful, little knowing that it can lead to security issues and computer repair. Viruses and spyware get into the system and crash the entire network. In such situations, Rollback Rx helps retrieve important data while removing all these unwanted elements from the pc network when a system restore is performed, preventing permanent damage and exorbitant costs.

Just imagine having the hard drive being deleted by a click of the mouse. When students handle computers, they are usually curious and tend to tinker around with settings and end up, sometimes unintentionally creating computer repair, putting the computer’s security at risk. When Rollback Rx is installed on the pc, it can be scheduled to take snapshots at specific intervals so that fixing computer problems becomes a quick task instead of creating several hours of downtime and data loss. This would avoid serious issues like certain scheduled activities being deactivated, antivirus programs being over-ridden or firewalls turned off, exposing the network to sabotage and other malware. With Rollback Rx, this sort of problem can be avoided and rectified easily, because it helps rollback the systems to a configuration that is suitable.

Rollback Rx system restore software is like a guardian for the PC network, avoiding computer repair and disaster through program failure or operating system malfunction. It keeps the system healthy and the user happy. While very simple to use, Rollback Rx has the options of selectively allowing only certain people to access it, thereby making it ideal where multi-user systems exist.

Ways To Hide Files On Your Computer


At some point in time, perhaps on your family computer, or your own computer, you will develop, collect, and store some important personal files on your hard drive that are strictly for your needs and purposes. These digital files may be so important to you, that under no circumstances, should anyone ever be able to access and see them. Some of these personal and business files may include documents, spreadsheets, emails, pdfs, text files, invoices, pictures, videos, and mp3s. These files may be so sensitive in nature, that you realize a need to prevent your spouse, kids, friends, or anyone for that matter, from viewing and accessing them. Perhaps, you may even need to hide porn or other explicit files. Just imagine if your spouse, or little ones at home, did a file search for all picture files and movies that were on your computer. Hopefully the results wouldn't expose them to anything that you wouldn't want them to see. Just imagine what could happen, if your children at home decided to fool around with your work and files that was listed in the recent documents menu. Ok, you get the point. And thus, this question is raised: How do I hide files and folders so that they won't be discovered?

There are several ways in which you can hide files: You can put your files within a folder and apply the hidden attribute to the folder. You can bury your files deeply in subdirectories within subdirectories and hope that no one browses using Windows Explorer. You can change the file name and file extension of your file to something unique and strange, so that no one recognizes it, or you can purchase a file hiding software security application such as a folder lock or folder hider with password protection.

All of the above methods may be your solution to hide your important files. It simply depends on the significant importance of your files and level of security you need. You can apply the hidden attribute to a folder or file by choosing to do so within its properties. This is a simple way of hiding a folder in Windows XP. However, the files will still show up if a user sets the option "show hidden files and folders" within the folders options. Another way to hide a file is simply by concealing it by dumping it into a folder you think no one will ever access. However, you run the risk of it appearing within the results of a Windows Search and having it displayed in the documents list. Another way to hide a file is by renaming it along with its file extension so that no one recognizes it or is able to open it using its standard program. Although this method could possibly work for you, you would have to waste time renaming it and changing it back to the correct extension.

And thus, the following question is raised: What is a quick and sure proof way to hide files in windows so that they won't appear within Windows Explorer and won't be displayed in the results of a Windows search? Your solution: A simple and easy to use folder security software utility that will allow you to hide files and folders and make them reappear all with a simple hotkey. Supreme Folder Hider is such a solution that will save you time and will provide you with an extra added sense of security. Supreme Folder Hider prevents all file access from Windows Explorer, the command prompt, shortcuts, and most recently used document lists.

Web Languages: PHP vs. ASP.NET


While the average web developer has a lot of options these days. It's really more of a bi-partisan system between ASP.NET and PHP, the rest being just independents. The battle rages between the supporters of the two languages, with no clear winner every coming out. While both can be used to complete the same project, it really depends on what you're looking for: price, speed, security, etc.

ASP.NET

If you program in ASP.NET you'll typically get too responses from the other side. Either you're rich (or your company is) or you're a Microsoft lover. While the name comes from Microsoft's old ASP technology, they made a huge leap with the .NET Framework, and the CLR allows you to use other languages for back end processing: typically Visual Basic.NET or C#.

ASP.NET's strength lies in object oriented features, and it's flexibility. Because of the CLR you can have C# programmers and VB.NET programmers working on the same project, or switch languages half way through and not have to rewrite all of your old classes. The .NET class library is organized into inheritable classes based around particular tasks, such as working with XML or image manipulation, so a lot of the more common tasks have been already handled for you.

Visual Studio .NET is a massive development IDE that (as long as your computer is fast enough) will shave tons of time of your coding. It has built in debugging along with IntelliSense, which allows for auto-completion of methods and variables so you don't have to memorize everything.

On the down side, ASP.NET is expensive. One it uses tons more resources on the web server so you'll require either better server or more servers in the farm. Windows 2003 and Visual Studio .NET are pretty tough on the pocket book as well. It's extremely rare for an ASP.NET app not to be running on IIS. And if you pay attention to any of the bug reports, you'll notice that Windows and IIS have had a bit of a history with vulnerabilities being exploited.

PHP

PHP works in combination of HTML to display dynamic elements on the page. PHP only parses code within its delimiters, such as . Anything outside its delimiters is sent directly to the output and not parsed by PHP.

PHP strength lies mostly in LAMP. The LAMP architecture has become popular in the Web industry as a way of deploying inexpensive, reliable, scalable, secure web applications. PHP is commonly used as the P in this bundle alongside Linux, Apache and MySQL. PHP can be used with a large number of relational database management systems, runs on all of the most popular web servers and is available for many different operating systems. This flexibility means that PHP has a wide installation base across the Internet; over 18 million Internet domains are currently hosted on servers with PHP installed.

With PHP 5 finally came exception handling and true OOP, but it still lack namespacing to prevent class naming collisions. PHP's type checking is very loose, potentially causing problems. Another drawback is that variables in PHP are not really considered to have a type. Finally, for some reason big corporations feel that if they're not paying for something, then it's not worth buying. If that's you're company's mentality, they just need to wake up and check out all the awesome free software that's out there.

So Which Is Better?

We'll I have my opinions and you may have yours as well. But in general, PHP is cheap, secure, fast, and reliable, while ASP.NET has quicker development time and is easier due to its class library system can probably be maintained more easily. Both are great languages, and it's up to you to make the decision.

DBA Degree Programs Are A Secure Education Choice For Solid Employment

A company's database is the heart and soul of client information. Databases store valuable information such as contacts, sales and income, financial statements and organizational plans for management, and to lose their database means a business can no longer function. Optimal care and maintenance of databases are becoming more and more important, as old accounts bog up space or the difficulty in retrieving information slows down productivity. Not only that, security in administration is a must in our high tech world, constantly under onslaught from viruses, hacker attacks and other subversive tactics meant to steal data and destroy competition. Proper care and effective management in handling databases and their administration is vital to any successful business that relies on computer technology to function, and a DBA degree program will help you acquire the necessary skills to become an integral part of an administrative team.

A DBA degree program involves learning the skills and getting solid training to be able to design, create and implement databases for important corporations and businesses. Knowing how to administer databases is also part of the practical, hands on training you'll acquire at educational facilities competent with information technology. Some institutions will include networking knowledge in the program so that you can effectively administer databases to their maximum potential. Learning the basics of networking and its application to database administration will help you become a valuable asset for multi-million dollar corporations or international businesses. Furthermore, a DBA degree will provide you with the analytical ability to troubleshoot and improve upon existing databases or design new ones that serve companies more effectively.

Security is a large part of working with databases and no company wants to discover that its database no longer functions, wiped clean thanks to an insidious virus. The popularity and ease of use of large capacity USB drives combined with curious human nature has made them a huge tool of those who would sabotage a company's functioning and databases are perfect places to strike. Learning how to protect against such threats and knowing effective backup and replication procedures to further safeguard a company's vital information is part of being a high quality database administrator. Only training will provide you with the abilities you need to meet today's standards of safety and archiving and a DBA degree program offers that know how.

Career opportunities are widespread for those who have the backup of accreditation and degrees. The investment of time and money in going after the training you need to become a valuable asset to any company is well worth the pay off, as businesses will offer strong employment packages to those who will help them protect their important information. What's more, a proper DBA degree program from a recognized educational facility will probably have employers come looking for you, rather than you having to pound the pavement with lesser skills. Colleges and universities also usually have career placement services available, with a bank of businesses looking for skilled people. The prospects of a strong, stable professional career are very good and the job market will open up to you, thanks to your newly acquired knowledge.

Finding a good, reputable educational facility to provide you with your DBA degree program is easy, as schools have developed websites with pertinent information for what you need. What's more, many schools offer different forms of financial aid or will help you locate sources to fund your education. Searching the internet turns up plenty of facilities with programs geared specifically to the information technology industry and you'll easily find a college or university that will give you the high quality education you need to be a contender in the database administration field.

The Importance Of An IT Degree

The explosion of the information technology world has created a need for highly skilled workers able to handle heavy programming and tight network security. Every end of the spectrum in the computer world now requires in depth training and knowledge to be able to meet the demands of a computerized civilization. Communications, databases and the number of computer networks mean that anyone breaking into the job market with the hopes of working with technology needs certified qualifications and solid skills to be a contender. Competition for employment is stiff and only those with proper knowledge will get into massive corporations or important jobs. Of course, basic training in PC repair will solidify a long term job for you in a computer store, but with the opportunity to expand your skills into something far more valuable, why limit yourself rather than specializing in programming, video game design or software development?

Working in the technological industry can be very good, as employment conditions are favourite. Most working hours are set at 40 hours per week, geared to when the maximum number of employees are using the networking system or tapping into the administrative database. Also, thanks to that same technology you would be studying, someone with an IT degree can easily work from home and provide the same service to their employer as they would on site. There are, however, some drawbacks to working in an IT environment: emergency situations such as viruses, massive backups or network repairs, or meeting a certain deadline can mean longer hours in the evening or on weekends, though usually not on a regular basis.

Technology changes rapidly and pressure to excel at skills does mean that those who work in the industry must always be continually updating their skills or learning new ones as developments occur. Of course, a secure, long term job position can mean that recycling skills may not be necessary, but should your IT employment with one company come to an end, you may find that you no longer have the qualifications to be competitive in the job market when searching for a new employer. For sure, businesses today nearly always only hire people with IT degrees and anyone lacking that certification won't be able to find a job, no matter how skilled or talented they are.

There's more reason to invest in achieving an IT degree. The job prospectus for someone with high skills and abilities is very good, and the public's desire for bigger, better, and more will continue to push companies to develop new software and find solutions to make individual's lives easier or more productive. Computer scientists and database administrators are predicted to be the fastest growing market for those with an IT degree, so specialization in those areas will ensure that you'll be quickly employed at a good salary. However, even without specialization, most people with an IT degree will land jobs, as companies are also looking for people with a wide range of knowledge, including interpersonal and business skills. Spreading out can make you just as valuable as specialization.

An IT degree provides you with the training so that you'll become a valuable asset to any company. Indeed, most businesses today seek out top students and professionals with certification from the best educational institutions to help them protect their valuable data and keep their computer network functioning at its optimal potential. The starting salary for someone with solid skills and certification begins somewhere around $60,000 and only goes upwards from there. Your investment in an IT degree will certainly pay itself back many times, and you'll be able to break into a rising area of employment opportunities that will have you set for life.
