Wireless Router Buying Guide

If you are in need of a wireless router and is shopping for one but have no idea which is the best wireless router for you, then you have come to the right place as I give you some of the things that you should consider before buying a wireless router. In the today’s market, wireless routers with varying prices and varying designs and speculations exist, and finding out which one best fits your needs may be the best way to get the best value for your money.

With the advent of various wireless devices, it can be confusing for a consumer to look for a wireless router. To make sure you are buying the right wireless device, make sure that it manages your internet connection for different devices without all the wires entangled and attached to them. A wireless router basically makes an invisible connection or network of all your devices and connects them to the internet. It uses a WAP technology or wireless access point and Ethernet router and switch. Look for words such as LAN or local area network and Ethernet when buying wireless routers.

The kinds of wireless routers may be confusing at first with all the letters attached to the number 802.11. These letters include B, G, A and N. They represent the kind of wireless router protocol supported by your wireless router. The letters show you how the wireless router connects with the other wireless devices. The most common wireless router protocol is B and G. Both B and G work on a 2.4 GHz frequency, which is also the same frequency used by other household appliances, making wireless routers with B and G protocols more prone to interference. The G protocol transmits up to 54 Mbps or megabytes per second whereas the B protocol transmits only up to 11 mbps. Another kind of wireless router protocol is the A protocol. It operates on 5 GHz frequency, thus making 802.11a wireless routers less prone to outside interferences. Unfortunately, there are less wireless devices that operate under the A network thus you must first check with your wireless device provider if they are compatible. The A protocol transmits up to 54 Mbps, thereby making it as fast as the G protocol. The newest technology in wireless routers today is the N wireless router protocol. It transmits up to 600 Mbps and has extended signals due to the new technology (Multiple Input, Multiple Output). The problem is, the Institute of Electrical and Electronics Engineers (IEEE) has not yet certified the N protocol and it may need some more maintenance than other protocols.

In selecting the appropriate protocol, take into account your internet connection. The fastest internet connection is up to 5 to 6 Mbps only. The 802.11b wireless router, even if it is the slowest from all the others, is still faster than the average internet connection. If you are not looking to transfer large files from one wireless device to another, I’d say the average B or G wireless router will do. Otherwise, why not try the new N protocol. Also look for wireless routers that have built in firewalls and are protected by Wi-Fi Protected Access (WPA) or WPA2. Before buying, also consider the range you want you wireless router to have. The usual range is from 120 to 150 feet but there are other wireless routers with longer range.

Toronto Flex Camp Data Services Presentation Roundup

1. Basic HTTP calls via <mx:HTTPService> - nothing special needed on the back-end, any server or app that can respond to HTTP calls can be invoked this way, and this is definitely the crudest (and generally least preferred) form of integration.
2. Web Service calls via <mx:WebService> - nothing special needed on the back-end, if you have code that is exposed as a Web Service, then the Flash Player can invoke it (although this generally does not perform as well as the next option).
3. Flash Remoting via <mx:RemoteObject> - this obviously requires a back-end that can respond to AMF requests, if you are a ColdFusion user than you have Flash Remoting built-in and so nothing more is needed, if you are a Java user then you'll want to install data services to give you this functionality (either BlazeDS or LiveCycle DS will do), and if you are using some other back-end then you'll want to look at community and 3rd party offerings (as a rule, use this option over Web Services).
4. Messaging via <mx:Consumer> and <mx:Producer> - this is what powered the chat apps and real-data push updates, and this does require data services on the back-end, and either BlazeDS or LiveCycle DS (including the LiveCycle integrated into ColdFusion 8) will do.
5. Data management and synchronization via <mx:DataService> - this is what powered the synchronized data editing screens (including pushing updates, conflict resolution, auto-commits, and more) and this requires LiveCycle DS on the back-end (sorry, BlazeDS won't do for this one).

Enterasys, Extreme hooking up?

Could Enterasys be looking at possibly acquiring rival Extreme Networks? There's been a flurry of speculation on that this week.

Enterasys has made no bones about its intention to acquire a sizable company that will take it close to $1 billion in annual revenue and better compete with Cisco and new enterprise LAN switch entrant Juniper Networks. Extreme and Enterasys both do about $350 million in yearly sales.

At Interop last month, Enterasys said it is getting close to acquiring.

Extreme would come at a bargain. Its market cap is about $374 million and it has $231 million in cash, making the net investment less than $150 million.

Do you need to meet PCI requirements?

Today, I was talking to one of Netcordia's university customers in the state of Texas. They have over 40 merchants and store fronts on campus allowing students and others to pay by credit card. And they've started to get audited at least once per year for PCI DSS compliance, as they have obligation to the credit card companies to protect end user data. 

They have started to use NetMRI for detecting configuration changes, monitor and manage policies, and make proactive changes.

The PCI Whitepaper has helped them see line-by-line what they need to do to meet PCI related issues on the network. But they are also interested in learning from our other customers on how they've tackled the PCI issue. 

Do you have PCI requirements? If so, what have you done so far? What challenges are you facing? Any words of advice? We'd love to know and learn from you.

How To Clean Your Computer Keyboard The Safest Way Possible

Needless to say, computer keyboards could come and go; and if you are exceptionally sloppy with yours, it is best to let the keyboards go, especially if it has served its time. If you have been fiddling mindlessly with your keyboard, removing the screws at the back and actually taking a peek into what has accumulated between the gaps, you just may have to stomach something not worth seeing before any meal. If dust bunnies have not yet mutated into the inner workings of your keyboard, you just may be surprised as to what else you might find in there: like food bits, animal hair, termites, enough DNA sampler to get you into the most wanted database…

Now there are several reasons why some people prefer to keep the keyboards they are currently using.

For one thing, most laptops do not have detachable keyboards. So unless you are willing to dig deep into your pockets for another expensive machine, it would be best to keep the one you are using and just learn how to clean it without damaging anything. Secondly, if you are one of those techie freaks out to get the latest high-end piece of hardware possible, replacing your keyboard with something more high-end may become very, very painful both on your pocket and your self-esteem. So here are a couple of tips on how to clean your computer keyboard the safest way possible.

But wait! When we say safest, we mean that you use prudent measures with a lot of rational thinking behind it. Sure, there are tips on how to use the dishwasher to clean your keyboards… and in some instances it may work. We just want to point out that most of these so-called dishwasher safe keyboards look cheap and about 2 minutes away from the rubbish heap. This is actually a great excuse to buy a new set of keyboards especially when the dishwasher ruins it. Besides, who in their right minds would put the entire laptop into the dishwasher?

So the equation goes: keyboard + dishwasher = heck, no. We hope that is clear.

For cleaning you keyboards, laptop of otherwise, you would need: a can of compressed air, several pieces of cotton buds, and a soft clean cloth dampened with a little moisture. You can buy the can of compressed air in most electronics stores. And yes, there is a difference between compressed air and WD40. Soft tipped cotton buds should be pliant enough to get into tricky gaps and corners. And lastly, use any soft cloth for wiping down. A chamois should work great because it does not leave any fibers behind.

First step is to give your keyboard some slight dusting with the compressed air. Use the dry cotton tipped buds gently to get to the gaps between keys, and use as many cotton tips necessary. Do not force the keys apart though. Once you are satisfied, give the keyboard a more thorough blasting of the compressed air. Once that is done, use the cloth (ever so slightly damp) and give the keyboard a wiping down.

First rootkit for IOS created

If you build it, they will come. So hold onto your hats now that the world has its first ever Cisco router rootkit, reports a story from IDG News Service. Sebastian Muniz, a researcher with Core Security Technologies, developed the rootkit for Cisco's Internetwork Operating System and will show it off on May 22 at the EuSecWest conference in London. Rootkits are stealth programs, extremely hard to detect. For the most part, they are aimed at Windows.

Creating Wordpress Themes from scratch.

This first article is meant to give you a global picture about creating Wordpress themes. Let’s start by answering a few common questions.

Do you need to know PHP to create or edit Wordpress themes?

The short answer is no. It would help to know some PHP but many theme designers don’t, and they do just fine.

Do you need to understand MySQL to create or edit Wordpress themes?

Again, no. Mysql is the database that drives Wordpress and is a key component … nonetheless, it has no impact on creating themes. So don’t worry about it.

What do you need to know in order to be able to edit or create a Wordpress theme?

I would say that you need to know three basic things:

1. HTML/XHTML
2. CSS
3. The Wordpress page hierarchy and behavior.

I think the first two are obvious, but the last needs some more explaining.
