The Xoops content management system comes with a modular structure allowing additional programs to be added to the core framework of coding. So far as Xoops is concerned, you have to download certain modules as compulsory add-ons. They are additional editors like word processor, backup module for your site’s data, diagnostic modules for managing your site. But the most important is the security modules (antivirus and firewall).

Although Xoops is claimed to be the securest CMS models, it has its own loop holes and if you are serious about the security issues of your site, you should never compromise in this area. Remember, the protector module is a must for your Xoops site. Once you have finished the installation of default Xoops framework, the first module you should add to the structure is the GIJOE’s Xoops protector module for getting added security features for your system, otherwise not offered by the Xoops default installation. Xoops protector module is specially designed to defend against any hacker’s attacks—-both on Xoops core structure and other modules.

So what types of cracker’s attacks this module can resist?
The Xoops protector module is supposed to make your site immune of such attacks as:
• DoS
• Bad crawlers or bot
• SQL injection
• XSS
• System globals pollution
• Session hi-jacking
• Null-bytes
• Wrong file path specifications
• CSRF

A few points to remember with regard to Xoops Protector Module
1. There is no need to install both anti-dos module and protector module; once you install the protector, you will need to uninstall the anti-Dos. The Xoops Protector comes with a built in anti-dos program.

2. Once installed, you will need to uncheck Xoops Protector Module Access rights for the Registered Users group under Blocks&Groups Admin.

3. You will need to check block Protector for the Anonymous Users group

4. Lastly upload a blank or redirecting index.html to the protector directory to prevent directory listing. However, a good web host is supposed to provide this by default.

Also make use of the outstanding feature of the Protector Module called the Security Advisory to check your Xoops installation for weaknesses.

You probably heard about datawarehouses & analysis tools in the past in database related discussions or in job meetings.

The fact is that everyday more and more companies are starting to think (and build) data warehouses or other data analysis and statistical tools.

It is no more a large-companies-only matter; today with the right knowledge and expertise (or a little education) small companies can also make analysis and get valuable information to boost sales or revenues.

So what is a datawarehouse?

In simple words, a Datawarehouse is a common repository (a database, for simplicity) of information about a company’s activities and operations.

This means, all your company’s transactions such as sales, payments or acquisitions end up in the data warehouse.
This “database” is a technical product or platform that allows us to “ask” real life business questions such as “which branch sold more products this month?” or “who is my top performing salesman?”

You may be thinking “I currently HAVE a database which records sales/transactions/movements of my company everyday”.
Yes, of course you have one of those. But that is a transactional database.

This means that this database is heavily used everyday to store our company’s operations, and because of this we cannot use it for analysis.
Also, this database holds data, not information.

A typical example for a record would be “Qty:1 Product_code: Shoes A Code_Branch: South …”. This is not meaningful for a report containing information, not only raw data that can not answer complex business questions which would allow us to make a manager decision.

These and a few other points are the key reasons to build a datawarehouse to do analysis.

So how I move or copy the data from my everyday transactional database to my datawarehouse?

Here is where ETL comes to play.
ETL is the process for Extracting, Transforming and Loading data from one database to another.

There are several ways for doing this, from coding your own processes to the more often used way of implementing ETL tools.

These ETL tools can do the job very well, and if chosen wisely can save you a lot of coding efforts and money, since you can graphically build processes and in most cases without knowing how to program for databases.

There are a lot of ETL tools in the market right now. As and advice, I suggest you to invest some research time (and testing if possible) before choosing the one that suits your company’s needs.

They can range from open source free tools to high price commercial tools. Neither of them is perfect in every situation, and you will have to take into account your data volumes, the analysis and answers you want from your datawarehouse, and the periodicity needed of those answers, among other aspects.

Raid data recovery is somehow different from all other types of data recovery. Most experts advise not to try to recover the data yourself before sending in the hard drives to a data recovery company. This is because most companies found that most of the times simple users try to recover the files all by themselves, they fail and not only. Their actions will make the recovery process even harder and if the lost information is important, someone will be in big trouble. If it’s about raid data recovery better handle it quick to the professionals without touching anything.

You don’t have to take chances with the recovery, it’s advised to research for a data recovery company that can handle the recovery process for you. Sometimes, it can be expensive for a raid data recovery but usually the price you will have to pay for the recovery is way lower then the price you will have to pay in time and resources to have all your data recreated.

There are procedures that data recovery companies always follow when they have a recovery on the line. These procedures are followed exactly and even expand when it comes to raid data recovery. As a first step in any raid data recovery, experts have to make sure that all drives are working. For Raid 0 as an example, it is a must for all the drives to be 100% functional. When they are not functional, the drives will be taken in the clean room and will be repaired.

When all the drives will function normally, clones of all the drives will be made. During this process, your drive will be placed in a write protect mode to make sure the data will not be altered in any way. The normal recovery process will be performed on the cloned drives, again, for increased safety.

When researching for a data recovery company you will notice some of them will offer a service full guarantee, if they don’t get your data back, you don’t pay. A phone consultation is something that could help you also. They will also offer you absolute 100% confidentiality on your data.

Even if raid data recovery sometimes can become expensive, most companies will not charge you for an evaluation of a complex raid system. If you need the help of the experts, get it, it’s the best way. After getting all your data back, make sure to always backup your information from now on.

I would like to say I have been into computer’s as long as I remember, I am a gamer at heart and I believe the best platform to play games is the PC. They carry more depth and are more replayable than there console counterpart.

If you look at some of today’s PC games like Medieval 2 and Supreme Commander, these are the true man’s thinking games. You won’t find these’s games on any other platform, neither will you see Cryis or Alan Wake coming to a “so called” next gen console near you. This is because they just cannot cut the mustard compared to a PC and yes I am talking about the Playstation 3 as well.

The sad fact is that console’s are always playing catching up, here’s the facts:

The Playstation 3 is using a souped up version of a 7800GTX for there GPU (graphics processing unit) witch was a outstanding graphic’s card for PC 2 years ago!

All the next gen consoles are raving on about High Definition gaming and watching movies witch was brilliant again but PC’s was capable High Definition 10 years ago!

The consoles are starting to build momentum with there online features and are starting to mature but when it comes to the PC, it’s not even comparable!

But the catch is…

But as good as these games are I must admit you do need a ninja PC to play these games at there best. Just to tot it up in your head to build a monster PC is a daunting thought alone. A top of a range CPU can cost you around $1000 if not more! You have to ask yourself is really worth it?

Well I can answer this for you if you still haven’t made your mind up. The answer is definitely a NO! I’ll let you into a little secret, you might be thinking I’m sat here typing this on my Titan PC witch you may be thinking is on par with the Deathstar. Well truth be known it look’s more like a clapped-out banger than anything the Empire can throw at you but it goes like s*%t of a stick though!!!

And guess what, this was all done through overclocking my CPU…

I would of carried on rabbling away but I ran out of space. See you on the other side.

We are increasingly living in a wireless world. WiFi hotspots continue to proliferate in coffee shops, libraries, hotels, and are now, with ambitious plans afoot for blanket coverage, even beginning to spread over entire cities. With more and more of the country kitted out with WiFi enabled laptops and a burgeoning new generation of WiFi phones and gaming equipment it seems we’re entering a brave new world of universal connectivity. It isn’t inconceivable to imagine a not too distant future in which you’ll be able to access the internet virtually anywhere at anytime.

The latest Wireless network venture in London will see a 22km stretch along the River Thames converted into a giant WiFi hotspot. If you’re prepared to live with relatively sluggish download speeds of 256kbps the service, which will initially stretch along the Thames from Millbank to Greenwich, will be free, if you need a faster connection, £2.95 an hour or £9.95 a month will buy you 500kbps.

According to MeshHopper the company behind the venture which is being branded as “online-4-free”, the one condition for those using the free service is that they’ll be required to view 15 to 30 second ads every 15 minutes, those paying for the faster service won’t have to.

This venture is being heralded as important not just for its huge scale but because it’s free. It follows on the back of a city-wide service launched in Norwich last year and anticipates a free network due to be launched in Manchester in August.

According to Dan Toomey, chief executive of Free-hotspot who joined forces with MeshHopper in the project “This really marks the arrival of free WiFi in Greater London. Millions of Londoners, as well as commuters, visitors and tourists can now expect to find free Wi-Fi as they work or play along the Thames.” Of course, whilst free to those willing to tolerate less than blistering speeds and the occasional interruption of ads, this is a undeniably a commercial venture. In this respect it will be competing with The Cloud’s offering which will cost £11.99 a month after an initial free month but may well give surfers faster speeds.

When Norwich launched its pioneering council run city-wide wireless network last year there was a degree of controversy with Broadband providers regarding it as potentially damaging competition; for this reason speeds had to be capped at 256kbps and sessions limited to an hour only.

Redundant Array of Inexpensive (or Independent) Disks with the acronym “RAID”, coined by a research group at UC-Berkeley, is a general term for data storage that combine an array of drives collectively to act as a single logical unit. They provide increased data reliability and/or throughput depending on the option or scheme. It is disk subsystem where a set of two or more drives (or discs) with a specialized disk controller contains the RAID operating function. The use of RAID can enhance performance and/ or is endowed with error tolerance.

RAID was developed basically for servers and stand-alone disk storage systems, but can be used on workstations like the desktop PCs. Desktop PC can have RAID added to its system by installing a RAID controller board and additional IDE or SCSI disks. More and more RAID functionality are being built on the motherboard.

Most Small to medium enterprises have gone in for RAID-configured data storage on their servers. RAID even though is very tolerant to faults; does fail sometimes. It may happen due to component failure that includes drive failures, missing partitions, controller failure etc. Data can be lost from RAID due to computer virus and worm damage, bad parity or drives out of order. But the most common cause is user error that often leaves the data unusable and corrupted.

RAID data recovery is very different to hard drive recovery as RAID is a more complex media device. It is more difficult and complicated to retrieve missing data due to drive order, parity, rebuilds, drive synchronization etc. There are six different levels with different way to spread data across multiple hard discs with specific use optimization at each level. It is essential to understand these levels for RAID data recovery.

Most RAID data recovery processes include certain steps like:
• Numbered drives
• forensically sound images of each drive are taken (exact bit by bit copies — including the blank or ‘white’ areas including the redundant drive or drives are taken)
• People in charge of recovering data reconfigure the data into a ‘virtual RAID’ on their multi terabyte server (Like HP Dual Xeon, 4Gb RAM, 8Tb SATA Storage, rack mounted, backed by UPS, backed up with a further 4Tb of storage)
• A list of files are made to be checked by the user to see if all the files he needs are there
• Copies of the data are made to a new drive or drives either external or internal as per the client specification.

The RAID data recovery is achieved through using the latest state-of-art technology, tools and techniques. However, it is ultimately the effort of the recovery experts and the software coders that differentiates between success and failure. An excellent perception and sense of pattern recognition are essential for recovering the missing data from complex RAID configurations.

Some things in life are just unwanted, but still, can happen to anyone of us. A thing like this is loosing your data from your laptop hard drive, we don’t want it, but can happen. All our important information got wiped out in a second, all of it. You can go to your tech friend or even to a computer store to ask what you can do about it but you will probably receive an answer that you can’t do anything with it.

We can prevent this by backing up all our information from the laptop hard drive in time but sometimes we just don’t think about it and the worst will happen. We know it’s our fault for not backing up the files. The good news is that now, we can investigate and research some data recovery companies and ask them for help.

The process for data recovery from laptop hard drives is usually more succesful then normal desktop hard drives, that’s good news also. This is because laptop hard drives were always built for mobility and are designed in such way to prevent severe hard drive crashes. The heads on a laptop hard drive are not likely to touch the platters, this can happen mostly on normal desktop hard drives. Because of this, the process of data recovery from laptop hard drives has a higher success rate compared with desktop hard drives.

Even if it has a higher success rate, the process is still difficult and expensive if done by an individual. If you would think about opening it up you will have to make sure to open it in a class 100 clean room. Bad news is that such a room costs about $50000 - $70000. Your best pick is to find a company that can handle the process for you for a cost.

If you don’t want to remove the hard drive from the laptop yourself, most companies will do this for you with no extra cost, you will be able to send them the full system. Also, most companies will not charge you if they will not be able to recover your data after the data recovery process.

Any type of data lost is something nobody needs or want, if data lost happen for your laptop hard drive is good to know that the odds are in your favor. Take some time to research for a good company and with some money you will be able to get your data back soon. After this, make sure to always back up all your data.

Software development, using quality business software, training and advice can drastically improve the efficiency of your business when done right, because:

1. After knowing which existing business software on the market might be suited for your company you can save a lot of time and money for not having to develop your own customized software, which is much more expensive most of the time.

2. Repetitive tasks (like e.g. sending a fax or dialing a phone-number) can be automated, saving huge amounts of time.

3. Investing in the right additional hardware equipment (like scanners, barcode labels, radio-frequency identification tags, label printers, etc.) can streamline your business processes. For example: it’s much easier to keep your inventory up to date and to find products easier in both your inventory and your business software.

4. By training you can learn how to do things differently and more efficiently. I often find people using Microsoft Software, like for example Microsoft Word and Microsoft Excel, but they only use the most basic functions. When I explain the more advanced functionality most often they quickly realize the benefits of it. I also talk to a lot of people who bought Microsoft Office, which also includes Microsoft Access, but they don’t know what it is, the benefits of it or how it works. Once I explain, they want to know more.

5. It’s much easier to quickly get an overview of the financial health of your company, where all the expenses went and which products or services brings the highest revenues.

6. Once the decision is made to invest in software development or buying existing business software, people usually think deeper about their business process, which often leads to new insights and improvements. For example, people often suddenly realise which business processes can be automated or improved upon. My experience is that this often leads to a huge increase in revenue in the future.

7. Most commonly, transactions are stored in a database, so it’s easy to retrieve old data which is great for tracking and tracing purposes.

8. It’s very easy to make all kind of reports, whatever the need.

9. More work can be done with fewer employees, saving lots of money. In some cases it’s also easier to get a detailed overview of the productivity of your employees.

10. It’s easier to set goals for your company and verify whether these goals were accomplished.

EMR (electronic medical records) is very beneficial to all medical practices, including chiropractic offices. Chiropractic billing software has many advantages for the medical practices that use them, and these programs do much more than just billing. Chiropractic software can encompass the files, notes, appointments and insurance claims instead of having a sea of papers filling up the office.

Since chiropractic billing software is so important, the offices who are thinking about investing in it must evaluate their needs to get the best product. The office staff can all provide input about what they want in a new EMR (electronic medical records) program. Since the staff of the office will be the one using it, they should have a vested interest in choosing the chiropractic software that will most efficiently handle their daily tasks. One of the most important features to look for in chiropractic billing software deals with patient data. Staff should not only be able to gather demographic data, but with many of these programs they are able to download copies of X-Rays and photos.

Chiropractors from around the country enjoy the many features of today’s chiropractic billing software. The ability to download X-Rays and photos alone is a valuable feature, not only for its practical uses, but also as a marketing tool. Chiropractic software programs can also make it easier to remember to send birthday cards, new patient welcome letters and mail merging. Many doctors also enjoy sending a personal note to their clients, which adds a personal touch. Electronic medical records have truly enhanced the work that all medical practices are able to do, including chiropractors.
