Wireless Access Points: Power over Ethernet

PoE gives you the freedom of installing wireless access points anywhere a ethernet cable will go. Before power over ethernet was available a wireless access point always had to be near a power outlet to give it power. This meant more money and usually bad placement.

PoE uses a device called a power injector to transfer the correct amount of power required to run the wireless access point. PoE uses the two unused wireless in a ethernet cable to run the power. Gigabit ethernet uses all the wires in an ethernet cable thus PoE is not available for Gigabit ethernet. Each client device that meets the standards of the PoE 802.3af amendment will be assigned a power class of 0-3 which will mandate how many watts they need. Often your wireless access point will be managed by a switch that will double as a PoE injector.

wireless access point placement is a major key for good security, both physical and wireless. If you are using a Fat access point which is located near a common power outlet or easily in reach of employees all it takes is a paper clip to reset the access point and your network has been hacked. Also placement is a major concern because if you install a wireless access point on the perimeter walls of you office you have just sent half you signal out side to the war driver passing by.

Remember when coming up with your wireless network budget do not let anyone say we dont need PoE. Compromising on placement of your access points will cost you security and money in the long run.

Sonys Playstation 3 Double System Launch

When the microsoft xbox 360 was released with two different versions, the tactic was debated endlessly regarding the merits of offering consumers a lower-priced bundle with fewer features. Staring a $400 price point in the face probably prompted microsoft to offer a lower cost package to point to when the xbox 360s price was inevitably criticized.

The Playstation 3 will probably blow those arguments out of the water in terms of scale as two versions launch, one console at a price point of $500, the other at a price point of $600. Most of the early adopters of the xbox 360 opted for the premium bundle and expectations are that the Playstation 3 crowd will be no different.

The two bundles each feature the infamous Blu-ray drive, a Bluetooth-enabled controller and an hdmi port for high definition output from the console. Similarities end there as the basic bundle includes a 20 GB hard drive to that package and calls it a day. Sony has priced that next-generation package at $500, a steep price to get a foot in the door of Sonys Playstation 3 vision.

Naturally, higher cost comes with more bells and whistles. In the $600 premium bundle, all of the basic bundle's features are included but the hard drive is bumped up to 60 GB, Wi-Fi is built in to the console and an on-board flash card reader is included. While the basic model's hard drive can always be upgraded and a flash card reader can be added later with an adaptor, those upgrades will likely come at a cost higher than the $100 difference between the models.

One point of debate has been Sony's reluctance to include hdmi cables with either bundle, more or less requiring the consumer to purchase the cable to experience the high-definition gaming so central to Sony's marketing strategy for the Playstation 3.

Composite cables can also produce a solid picture, so that might take some of the sting out of the announcement, but the move is still a disconnect from the marketing message describing the ultimate, high-end gaming experience. Sony's specific Playstation 3-branded hdmi cable will retail for $50, but other HDMI cables can be had for less.

To round out the accessory costs of the Playstation 3, the console's special SIXAXIS controller, complete with motion-sensing ability, will retail for $50. A remote specially made for the Playstation 3s Blu-ray player will retail for $30 and perhaps the most important accessory of all, games, will see a $60 price point for Sony first-party games.

Sony has truly entered a new realm for high cost and it will be up to the Playstation 3 to make consumers and critics alike focus less on the money involved and more on the high-end gaming experience that Sony is trying to achieve. time will tell whether Sony will emerge the victor.

My Life with the Sims

My favorite computer game of all-time is "The sims" and I was not surprised at all when I read the news announcing that the game was voted as one of the most popular and best-selling games of all time, based on an online survey of PC gamers.

According to the games distributors, Electronic Arts, the virtual-life sims game has sold over 7 million copies worldwide as of 2002, dislodging Myst as the top-selling computer game of all time. First created by Will Wright and Maxis, The Sims has spawned a number of expansion versions which, if taken into account, would reflect total worldwide sales of The sims series at over 13 million.

Since the game was first issued to the public on February 4, 2000, there have been seven expansion packs that followed as well as a sequel, The sims 2.

What makes the game so appealing is its unique gameplay. Instead of meeting a set of objectives like the great majority of computer games, The sims allows players to engage in a fully interactive environment and the sims characters can make their own choices about everyday living. The challenge to the player is how to best spend the Sims time in a "virtual day." And like real life, the only real objective is how to organize the Sims time and activities to give him maximum happiness and to help him attain his personal goals.

One unique quality of the sims is that, like real people, they also possess a certain amount of free will. This allows them to ignore a player's commands if they wish and instead embark on something that they consider to be more pressing and important, just like real people. For instance, a player may order a Sim to go to the supermarket or visit a friend, but if the Sim is tired and fatigued, it may simply fall asleep instead to restore its energy.

Players also have control over how their Sim character relates with other characters. For instance, they can make the Sim a real jerk who insults, slaps or even attacks other sims, which, just like in real life, often means that they get insulted, slapped around and attacked in return.

Buying Wholesale Sports Apparel

When people want to dress well even when playing basketball or football, the clothes worn have to fit the part. This means wearing something like Fubu, Nike or reebok instead of some cheap knockoff that will get torn after a few washes.

The quality of the thread used plays a big part in the cost of the shirt. Discounts or sale events only happen when the season is about to end so if the person wants to be in style, the customer has no choice but to pay for it.

Is there no way to get a good bargain? Yes there is because there are sites on the web that buy these from suppliers at wholesale then sell it to people at rock bottom prices.

An example could be a Nike pair of shorts that will cost $24.99 in the sporting goods store. Believe it not, these same item can be purchased off the internet for just $8.99. This means the customer can almost get three items for the price of one.

Things like these are considered to be a good bargain and those who want it will just have to give the credit card details and once approved, the company will have this prepared and delivered to the clients home in a few days.

There is another reason why many people are using online wholesale websites aside from the price. The individual can go online anytime since the store is open 24 hours a day seven times a week so there wont be any pressure in looking over any time before deciding to purchase it.

Though there might be a problem with the fitting, this can be avoided by going into a store and fitting a similar item.

online sites dont only sell clothes but other items as well. If the customer is satisfied with the matching top and bottom, there are also sports accessories such as socks, shoes and bags that can be taken to the gym, court or field.

Being fashionable doesnt always mean shelling out a lot of money as long as there are online stores that are able to buy these and sell it at discounted prices. The person will just have to find it in the Internet to be able to look and feel good instead of waiting for few months to pass when these retailers go for the end of season sale.

Laptop Data Safety

basic levels of password protection on laptops are easily overcome by the experienced thief and this is causing considerable concern within the industry.

There are two things you should do:

1. Physical security - Don't let your laptop out of your sight. Never leave it unattended in a public place. Never leave it in the boot of your car overnight at hotels. Always use a steel cable to attach it to a firm structure when in use outside your normal environment.
2. Electronic security - Don't have sensitive data on a hard disk in the first place. Use a complex password and if possible second level authentication, such as a token or other device. When the laptop is on but is not being used, use the electronic lock facility to activate the password entry facility. Use a password on any screensaver.

That takes some account of security for the laptop, but with attached devices such as SD cards and usb pen-drives the situation is different:

Anyone stealing the SD Card or pen-drive can read the data on any computer loaded with similar software. This is clearly a point of vulnerability; the best method to protect this type of device is to encrypt it so that it is useless without the decrypt key.

This protection is not the expensive option it used to be, with open source software freely available. The best of these encrypt and decrypt on the fly and are transparent to the authorised but render the device useless to the thief and in may cases appear to be a blank device.
