Are You Too Young For A Mobile Phone?

Sunday, May 25th, 2008

Mobile phones have become a part of everyday life, and many people can not imagine how they lived without one. There are so many different types of mobile phone now available, with all types of different features such as MP3 players, cameras, video recorders, internet browsers and email clients, so it is no wonder that the latest, flashiest mobile phones are wanted by children and teenagers everywhere.

Kids always want the newest toy or gadget and mobile phones are high on their wish lists. But at what age should children be allowed to have a mobile phone? Some parents allow their children to have a mobile phone when they are still in primary school, and although they can be a good safety measure allowing contact between parent and child at all times, parents should still think about whether or not a mobile phone is really needed, or if its just a fashion statement.

Some parents take out contract mobile phones for their children as they find it cheaper than paying for a pay as you go handset up front, especially if purchasing an expensive handset. This isn’t always a good idea as there is no way of limiting calls on a contract, and children can run up high mobile phone bills, especially if they do not understand the network charges. You must be 18 to sign up to a mobile phone contract in the UK and there are good reasons for this.

So how old should your child be to have there own mobile phone? There is no specific answer but parents should take the advice below into account.

If a mobile phone is needed to keep parent and child in touch, opt for a pay as you go deal preferably with a cheap handset. This will allow you to stay in touch with you child, they won’t be able to run up a high bill, and thieves shouldn’t target them for there expensive handset. Stick to these simple tips for hassle free mobile phones for your children.

This and many other articles on mobile phones and the latest mobile phone deals was written by John Gray.

What Is ERP SAP, Exactly?

Friday, May 23rd, 2008

It is rather hard to pin down the meaning of ERP SAP. ERP, as we know, stands for Enterprise Resource Planning. In that case, what does SAP mean? SAP is an information technology acronym that when spelled out means Session Announcement Protocol. It is a form of announcement protocol that is employed for multicast sessions so that potential participants can be informed about pertinent session setup data. An SAP is usually dependent on the Real-Time Transport Protocol.

But there is also another way the SAP acronym is used in the IT world. SAP may also be used to mean Service Advertising Protocol which is employed so that servers linked somehow to the network will be identified through their respective addresses and services. In this case, SAP functions as a Netware protocol. Service Advertising Protocol allows the Server Information Table to function like a phonebook which would require NetWare clients to be knowledgeable about the real address of the server or service that they want before they can access it. Should the server that you want be unavailable, a broadcast packet that would indicate that status is delivered to the Server Information Structure. SAP agents are periodically informed about the status of a server every 60 seconds when a new broadcast packet is delivered. If there is no new periodic broadcast delivered in the span of 3 minutes, the server is called a downed server. The SAP agent will then eliminate the information about the server from the table, and is responsible for initiating a new broadcast with the information that that server is a downed server. This process permits SAP agents to maintain updated Server Information Tables.

A third way that you can derive the meaning of SAP is if it is used to refer to the Systems, Applications and Products in Data Processing company, derived from the name SAP America, Incorporated. This company houses the American operations of the software firm SAP AG of Germany. SAP AG is currently believed to be the dominant player in the world for business software solutions. Based on revenues, SAP AG is considered the third-biggest independent software developer in the global industry as well. SAP works for six different sectors in the software industry, namely, Public Services, Financial Services, Service Industries, Consumer Industries, Discrete Industries, and Process Industries.

SAP AG does not concentrate on serving just large enterprises — it also serves small- to medium-sized companies as well. SAP AG is known to have helped introduce the ERP or Enterprise Resource Planning concept which is why the company focuses on ERP systems and ERP solutions in its array of services. In the US, SAP America competes directly with major player Oracle Corporation, with the latter even initiating legal action against SAP for allegedly illegal corporate practices conducted by the SAP subsidiary SAP TN. In turn, SAP denies it has committed intellectual property theft from Oracle.

How to Get in Golf Shape - Part 4

Wednesday, May 21st, 2008

Now we are ready to move onto the Initial Takeaway. This is a very important part of the golf swing because if you mess this up it is next to impossible to get your swing back on track. The first 18 inches to 2 feet can very well determine the type of swing you will have.

The takeaway is what sets in motion the sequence of events that will allow you to deliver the club to the ball in the way that you need to in order to produce the shot you want. You should be letting your upper back and shoulder muscles initiate the takeaway and not your arms.

The first exercise to help with the initial takeaway is the seated hand to floor reach. You are going to sit in the upward position that you would be in if you just did a sit up. While maintaining this position stretch your arms straight out and rotate them to one side until you touch the ground. Then, rotate back to the other side. Perform 10 to 12 repetitions for 3 sets.

The second exercise to help with the initial takeaway is Lat pulls. These can be performed at your local gym with a pulley machine. Ask a trainer to direct you to the lat pull machine and they will be able to show you the proper way to perform this exercise in about a minute or so.

The final exercise to help with the initial takeaway is the overhead should weighted stretch. You will need dumbbells for this exercise. Start with the dumbbells in your hands and at your sides. Next, raise them all the way to above your head while keeping your arms straight. Do 3 sets of 10-12 repetitions with this exercise.

Now you have exercises to work the muscles that you use for your setup and for the initial takeaway. These are very important parts of the golf swing and you should exercise these muscles regularly.

Computer Forensics Examiners

Tuesday, May 20th, 2008

A computer forensic examiner is a professional who uses investigative and analytical techniques to be able to provide digital evidence.

The International Society of Forensic Computer Examiners is the organization, which provides the CCE or Certified computer Examiner certification for those individuals who would be interested in trying out or making a career in Computer Forensics.

This CCE certification is basically provided to be able to advance and make the field of computer forensics more professional. This certification also provides an uncompromised and fair process to be able to certify the capability of a computer forensic examiner. This certification is recognized universally, which helps in the setting of forensic standards to be high and ethical for forensic computer examiners.

The CCE certification could only be given to those individuals that have no criminal record at all. The examiners are only certified once they pass the online exams as well as successfully perform the actual forensic examinations done on three test medias. Additionally, the certified examiner should adhere to the code of ethical standards of the ISFCE and his or her professional responsibilities.

Also, prior to trying out to be certified, it would be recommended to have a proper understanding of the basic rules of evidence, because this would be related to the acquisition or seizure of magnetic media, marking, handling as well as the storage of electronic evidence, the right to privacy and the chain of custody.

Computer examiners are also trained to be skilled on proper evidence handling and documentation. Equipped with investigative instincts and a logical thought process, these individuals have the ability to operate on an extremely professional level.

Do Not Toss That Hard Drive!

Sunday, May 18th, 2008

Christmas has come and gone, and many of you may have gotten a shiny new computer from Santa Claus this year. But before selling or giving away your old computer, you must prepare the hard drive for disposal. That means properly erasing all your files, to ensure that no confidential or sensitive information remains that is easily accessible.

Data is almost always at least partly recoverable. Recently an author bought a hard drive on eBay that had been used by a clinic. It had more than 30,000 credit card numbers on it. Drives purchased this way usually contain confidential data. Deleting your files or even reformatting the hard disk is not sufficient. Why?

Your hard disk has an index like the table of contents of a book. Say you do not want Chapter 6 anymore, and you delete it. Your PC just marks Chapt. 6 in the Table of Contents as empty. In other words, the area on the disk occupied by Chapt. 6 is now marked as available for other files.

But note that nothing else has happened. The actual data forming Chapt. 6 is still there, happy as a clam, in the same place on the disk. Much the same thing happens when you reformat your disk. In short, deleting files or reformatting the disk just removes the references to the data in question, not the data itself. This is why deleted files can be recovered with specialized software such as Disk Investigator. Data can even be recovered from reformatted disks. So what to do?

Before putting that old computer out with the trash or giving it away, go to one of these sites for a program that will wipe your individual files or entire hard drive. Note that some of these programs will erase Windows as well; in that case, of course, your old computer will be unusable.

http://www.heidi.ie

http://www.killdisk.com

There are many other similar programs available. Drop by your favorite search engine, and rummage around. These programs will ensure that your data is beyond recovery, for all practical purposes.

On a related note, you should also take precautions before sending your PC to the repair shop. Even if you trust the technicians with your stuff, your files may be deleted during the repairs. If your machine is working, back up all your important or sensitive files. Use a handy USB thumb drive or external hard drive, or one of many online (and free) storage services.

Personally, I prefer to use my own storage devices. This way, the data never leaves my hands. Whatever backup method you use, check that it successfully copied your files. Then delete those confidential files from your hard drive. You can reinstall them when you get your computer back from the shop.

How to Get in Golf Shape - Part 6

Saturday, May 17th, 2008

We have covered quite a bit in this series, but we still have a few different parts of the golf swing to cover. Getting in golf shape requires some dedication and you will need to do some of these exercises every day for about five days a week. This part will cover the initial downswing.

You have done everything, up to this point, to coil up and store energy. Now you need to unleash that energy. The lower and upper body need to stay synchronized and you need to allow your legs to lead. This is all necessary to create the best downswing possible.

The first exercise to help you strengthen the muscles used in the downswing is the pillar stabilizer pushups. These are like a regular pushup, but you put your forearms on the ground so that you are bending only at the elbow and then pushing yourself up. These are not the easiest to do, but they will work the necessary muscles very well.

The second exercise is the front lunge. You can do this exercise with or without weights. You will start in the standing position and step forward. Lunge with your front leg until it is at a 90 degree angle. Next, step back and do it with the other leg. This will work your legs in full and will help you with your downswing lead.

The last exercise for the downswing is the squat. This exercise can be done against a wall or with weights. You want to start in the standing position with your legs shoulder width apart and bend at the knees until your legs make a 90 degree angle. Then, go back up to the standing position and repeat.

Now we have gotten you all the way to the initial downswing. There are still a few parts left and we will cover those in the next few parts of this series. So far we have gotten your golf swing off to a great start.

Wireless Network Security

Thursday, May 15th, 2008

Working from home has its advantages, including no commute, a more flexible work schedule and fresh coffee and home-cooked meals whenever you want.

But working from home while using a wireless local area network (WLAN) may lead to theft of sensitive information and hacker or virus infiltration unless proper measures are taken. As WLANs send information over radio waves, someone with a receiver in your area could be picking up the transmission, thus gaining access to your computer.

They could load viruses on to your laptop which could be transferred to the company’s network when you go back to work.

Up to 75 per cent of WLAN users do not have standard security features installed, while 20 per cent are left completely open as default configurations are not secured, but made for the users to have their network up and running ASAP.

It is recommended that wireless router/access point setup be always done though a wired client.

Change default administrative password on wireless router/access point to a secured password.

Enable at least 128-bit WEP encryption on both card and access point. Change your WEP keys periodically. If equipment does not support at least 128-bit WEP encryption, consider replacing it.

Although there are security issues with WEP, it represents minimum level of security, and it should be enabled.

Change the default SSID on your router/access point to a hard to guess name. Setup your computer device to connect to this SSID by default.

Setup router/access point not to broadcast the SSID. The same SSID needs to be setup on the client side manually. This feature may not be available on all equipment.

Block anonymous Internet requests or pings.

On each computer having wireless network card, network connection properties should be configured to allow connection to Access Point Networks Only. Computer to Computer (peer to peer) Connection should not be allowed.

Enable MAC filtering. Deny association to wireless network for unspecified MAC addresses. Mac or Physical addresses are available through your computer device network connection setup and they are physically written on network cards. When adding new wireless cards / computer to the network, their MAC addresses should be registered with the router /access point.

Network router should have firewall features enabled and demilitarized zone (DMZ) feature disabled.

You can test your hardware and personal firewalls using Shields Up test available at http://www.grc.com

All computers should have a properly configured personal firewall in addition to a hardware firewall.

Update router/access point firmware when new versions become available.

Locate router/access point away from strangers so they cannot reset the router/access point to default settings.

Locate router/access point in the middle of the building rather than near windows to limit signal coverage outside the building.

While none of the measure suggested above provides full protection as counter measures exist, a collection of suggested measures will act as a deterrent against attacker when other insecure networks represent easier targets.

Do Touch Screens on Mobile Phones Actually Work?

Wednesday, May 14th, 2008

Touch screens on mobile phones are becoming commonplace in today’s technology crazy environment. At one time it was only the smart phones that commanding such a privilege. Now as the cost of this technology comes down, more and more mainstream devices are being fitted without keys. In this article we ask, can touch screens really replace the good old keypad? Or are we replacing old technology just for the sake of it.

Over the past year there have been many mobile devices that have been released with touch screens. First there is the LG viewty, one of LG’s best offerings. The lack of keys can often make it difficult to type in text messages, but the front of the phone does look as slick as can be. In terms of functionality, it performs most tasks well and there is a big improvement in performance when surfing the web.

Next there is the stunning iPhone. This offering from apple is nothing short of breath taking. They have got the touch screen just right making it easy to text and write emails with its ultra responsive screen. Some have said that the price is too high for a device that is not even 3g, but apple know their market and know that they have a loyal following who are willing to pay top dollar for anything that they make.

Then there is the Sony Ericsson W960i. Sony Ericsson have been using touch screens on their p series mobile phones for years now. The W960i is the first time that they have crossed over to the W series and the response so far has been fantastic. Some say that the stylus is a little cheap, but this is a small fault that will be rectified in future models.

Overall we can see that all of these mobile phones perform well with a touch screen. Whether they provide the functionality provided by keypads remains to be seen. Perhaps for the time being manufacturers should follow Sony Ericsson and add both a touch screen and a keypad. At least this way you get the best of both worlds.

Mark Hirst runs a website dedicated to finding you great mobile phone deals. If you would like to purchase the LG viewty then you can visit his site. If you would like to view Sony Ericsson w960i deals then why not pay this specially designed page a visit?

Intellectual Property — Patentability of Computer Programmes - Exclusions

Tuesday, May 13th, 2008

In the recent judgment of Re Shopalotto.com (2005), the Comptroller refused a patent application for a computer programme that permitted a user to play the lottery on the grounds that it was excluded from patentability under the provisions of the Patents Act 1977.

Shopalotto.com applied for a patent of a computer apparatus configured to provide a lottery playable via the Internet. The apparatus provided a web server and further software conditioning the machine to receive, store, select and compare. This enabled the computer to operate in a new way—to permit a user to play the lottery. The application was rejected and Shopalotto.com appealed this decision.

The patentability of the computer apparatus was examined in light of the exclusions under paragraph 1(2)(c) and (d) of the Patents Act 1977. These provisions exclude from being patentable, a scheme, rule or method of performing a mental act, playing a game, or doing business, and computer programmes and presentations of information.

Re Shopalotto.com argued that this claim was a game, conceptually no different from a board game, and therefore patentable as a result of a note from Official Ruling 1926(A) (1926) 43 RPC Appendix page i, which stated that a playing game would meet the requirements of an invention under s.93 of the Patent and Designs Acts, 1907 and 1919.

The Deputy Director of the Comptroller determined that the Official Ruling guidelines on the interpretation of the 1907 and 1919 Acts were not valid guidelines for interpreting the 1977 Act. Furthermore, as there have been difficulties in interpreting the 1977 Act, the court would refer to Article 52 of the European Patent Convention, which has the same effect as the 1977 Act.

The Deputy Director concluded that:-

▪ the first test to determine whether a computer programme is an invention is whether the inventor has contributed over and above a computer operating in a new way as a matter of substance;

▪ the second test is to determine whether the contribution lies in an excluded matter or, on the contrary, whether it creates a technical contribution or effect;

▪ in this case, it was unnecessary to make a search on the contribution to the art as computer programmes are notorious and the court could therefore apply common sense;

▪ the programme provides a web server to the Internet, which is a common service; and

▪ there is no contribution to the art outside of the provision of various pages to view the pages provided by the server.

The Deputy Director therefore dismissed the appeal.

Lowering Cost of Technology Could be Decisive in HD Disc Format War

Monday, May 12th, 2008

As the hold that Sony’s Blu-ray high def DVD format has on the market continues to get stronger in the face of opposition from the competing HD-DVD format, there are a number of things that Sony could do in order to secure a sure victory. One of them is lowering the cost of its Blu-ray disc players.

There’s a lot of evidence to support the idea that this move would make for a sure victory over HD-DVD. Most of this evidence comes in the form of sales statistics. Right now, despite the fact that Blu-ray players cost roughly twice as much as HD-DVD players, there are just as many Blu-ray disc players in American homes as there are HD-DVD players. When you add in the number of Sony’s Play Station 3 video game consoles- which also function as Blu-ray players- the number of Blu-ray players in American homes is significantly higher than the number of HD-DVD players out there. Combine those statistics with the fact that Blu-ray discs have outsold HD-DVD’s in the past couple of months by a margin of over two to one, and it becomes pretty obvious that consumers as a whole like the Blu-ray format more than the HD-DVD format.

There are several reasons why the Blu-ray format may be more popular among consumers than the HD-DVD format. The most obvious technical difference is that the Blu-ray format can encode a lot more data onto each disc than the HD-DVD format can. This translates into longer movies and more bonus features that can be included on Blu-ray discs. Since both High Def DVD formats are also optical discs just like DVD’s and CD’s, there are plenty of computer applications for the technology as well. More data storage capacity translates into being able to deliver more software on each Blu-ray disc than on an HD-DVD disc. Blu-ray is also a better choice for data archiving than HD-DVD. Specifically, the HD-DVD format can only store fifteen gigabytes of data per side of the disc while Blu-ray can store twenty five gigabytes of data per side of the same sized disc! With that kind of a difference, it could be argued that even if HD-DVD was the winner of the format war, it would end up being replaced by something like Blu-ray anyway. Using Blu-ray now, just skips that step.

With the overall popularity of Blu-ray, Sony could secure its win in the format war by lowering the prices of its players. Losses of profits from the players could more than be made up for in coming years by licensing and royalties from having a monopoly on the high def DVD market. Also, as the cost of producing Blu-ray players goes down, Sony will eventually be able to profit on sales of them as well. Unfortunately Sony has been unwilling to make that effort so far, but another company called Funai will force the price of Blu-ray players down by introducing their own Blu-ray players onto the market that will cost around five hundred dollars a piece- a figure much more in line with what HD-DVD players cost.

It’s interesting that a little known company could secure a victory in the format war for Sony by doing what Sony has so far refused to do for itself.
