Introduction to ADSL

Your Service Providers ADSL service operates over a normal telephone line. This means that your telephone line can be used to send and receive high-speed digital data and make phone calls at the same time.

ADSL transforms the twisted copper pairs of wires between the local telephone exchange and your telephone socket into a high-speed digital line. It is called “asymmetric” because it moves data more quickly from the exchange to you than vice versa. This makes it ideal for applications where you would typically receive more data than you transmit, such as use of the World Wide Web and reception of digital audio/visual material. ADSL is the first generation of Digital Subscriber Line (DSL) technology.

Think of ADSL in this way when you download a web site page onto your browser. The request you send the system to download the page is much smaller than the page itself, so the system is designed to make the most of available bandwidth to fit in with the way you typically use the Internet.

Introduction to Wireless Networking
This section contains some Wireless Networking basics to help you better understand how a wireless network works.

Networking
A network is two or more computers connected together sharing Internet connection, files and peripheral devices such as printers. A wireless router allows your computers to connect to the Internet without wires. This lets you move a laptop computer around while staying connected to the Internet or lets you locate a desktop computer in a room that cannot easily be reached with cables.
Your wireless router Base Unit forms an Infrastructure wireless network.
Infrastructure Network
In the infrastructure network a Base Unit is used as the central point of all communications and acts as a gateway to the Internet. The Internet connection is automatically shared between all computers associated with the Base Unit. As a result, laptop or desktop computers on your wireless network can connect to the Internet as if they were directly plugged into the ADSL socket.

Ad-Hoc Network
An Infrastructure Network which is the most efficient way to share an Internet connection. For information, this section describes the other type of wireless network, the ad-hoc network, also known as peer-to-peer network.

In the ad-hoc network, computers communicate between one another without the need for a Base Unit. Windows Internet Connection Sharing can be used to share an Internet connection available on one computer between all computers on the network. At least one computer must already be connected to the Internet and be switched-on for other computers to access the Internet.
Wireless Network Settings

A Wireless Network is defined by the following settings:
Wireless Network Name (SSID): Identifies your wireless network.
Channel: Wireless Networks operate in the 2.4GHz frequency band where 14 channels are available. Devices must operate on the same channel to be able to communicate. In an infrastructure network, the Base Unit controls the channel allocation.

Security: You can use Hidden Name (Hidden SSID), WEP (Wired Equivalent Privacy) or WPA (Wi-Fi Protected Access) mechanisms to ensure the integrity of the network. More about Wireless Security…

Wireless Security WEP WPA WPA-PSK

Wireless routers are designed to be easy to protect against unwanted connection. It is recommended that you set-up security as soon as you have successfully installed the product and checked that default settings work to connect to the Internet.

WEP and WPA wireless security mechanism to protect data transmitted over the wireless network and to prevent unauthorised connection. Access list based are based on MAC Addresses so you can specify which wireless adapters are authorised to use your network.
First you need to decide the type of wireless security you want to use. Please Consult your Router Manual.

WEP
WEP (Wired Equivalent Privacy) is the security used as standard in older 802.11b wireless networks. Select 64-bit WEP or 128-bit WEP if: You wish to connect older wireless adapters that do not support WPA (see opposite) such as the BT Voyager 1010/1020 to your wireless network now or in the future WPA or WPA-PSK

WPA WPA-PSK
WPA (Wi-Fi Protected Access) is the next generation of security for wireless networks. WPA-PSK is the version of WPA specific for the home or small office users because it does not require an authentication server. With WPA-PSK, your network key is regularly and automatically changed so hackers cannot decode the key by listening to your connection.

Select WPA-PSK if: All your wireless adapters support WPA. Check your wireless adapter’s specification.
You wish to benefit from the additional security offered by WPA over standard WEP

For help on Enterprises security with WPA or 802.1x,  please refer Router Manual

Is My Site Up

Is My Site Up #IsMySiteUp

Many shared hosting websites and VDS virtually dedicated servers are single point hosting. Meaning your site exists on a single server unlike a CDN Content Distributed Network.

Most web servers  in their SLA’s (Service Level Agreements) state a 99% uptime on your business website.

This equates to more than 3 days of it being down in a year. How much does your business stand to lose in three days?

There is a solution…drum roll…IsMySiteUp.org

IsMySiteUp.org is a cloud-based service that monitors your website 24/7and alerts you when your site is down via email and SMS texted message.

 So you can react within minutes and get your site back online.

5 tips to safer online buying

Five tips to safer online buying

1] Check the name of the website
Always carefully check the spelling of the website address or URL – if anything is misspelt, it’s likely to be an unofficial site.

2] Check the address
It’s not just the web address you should worry about. It’s well worth checking out the postal address too.

3] Look for the padlock
When you go to pay for your purchases, check the website has a secure way of paying. Make sure you look for the padlock symbol ‘https://’ as opposed to ‘http’ – the ‘s’ signifies it’s secure.

4] Pay carefully
If your order is over £100, one of the best ways to pay is by credit card.
That’s because you’ll be protected by Section 75 of the Consumer Credit Act (1974), which will give you valuable consumer protection if there’s a problem with your purchases.

If your order is under £100, look to use a Visa debit card so you can make a claim under the Visa Chargeback scheme.

5] Keep your receipt
Once you’ve made your payment, always keep hold of the order confirmation in case of any dispute.  That way you’ve got proof of your order and payment.

Winter Checks for your car, a DIY guide

In this quick guide I will demonstrate how you check your car is ready for winter.

Under the Bonnet

Under the bonnet you will notice things are colour coded.

Checking the Engine Oil

  • Remove dip stick
  • At the end of dipstick you have a marker to check the oil level
  • Unscrew oil cap and put the oil in, one pint at a time, let it settle for a few minutes.
  • Check with the dipstick again until oil is visible.

Break fluid check.

  • Look for the minimum and maximum level
  • This is a visual check only.
  • If you notice the level low, do not drive. Call your mechanic or your breakdown service.

Engine coolant check

  • This is a visible minimum and maximum check.

Windscreen washer fluid

  • A visual check
  • It has a minimum and maximum level
  • Use a third of the solution with water.

Tyres

After checking under the bonnet the next thing to do is a visual check on the tyres.

You want to check the right side edge for tears and bulges.

Look at tread. The reason you have tread is to remove water from the tyre and it helps the tyre grip to the road and to break safely.

 If tread runs flush with markers then it is time to change your tyres.

 If you have a spare tyre in the boot, be sure to check that too.


Lights

Checking your lights is a visible check.

  • Check that they are clean, and not damaged.
  • Put the side lights on and inspect them.
  • Check your dipped lights.
  • Check your fog lights.
  • Check the left and right indicator.

 Do the same at the rear of the vehicle

Do a visual inspection to check they are clean and free from damage.

Get a friend to press the break pedal.

Next you want to check the Windscreen wipers and washer is working.

As you can see I have already topped-up with Windscreen washer fluid.

Make sure your wipers are actually clearing your screen, if not you may need new wipers.

Common Sense

There are a few common sense things you can do before you embark on your journey.

If the weather is particularly bad like heavy snow or dense fog, ask yourself do I really need to drive?

If you are going to drive, then you will need to remember the following:

  1. Check the weather forecast, take a little food and water with you.
  1. Have plenty of fuel at least a quarter level depending on your journey.
  1. Always have an alternative route planned.
  1. Be sure to charge your mobile phone in case you need to make an emergency call and finally subscribe to a breakdown service as be sure to have  your membership card or details with you before you set off.

Justice for Damini movement

For all those who were unable to be a the vigil today, you will be able see 14 minutes of highlights that I have just finished editing. I am in the process of uploading this footage to YouTube. I will post a link on this page when it is complete.

Thank you Reena for getting us all together, and to all the speakers who were marvellous and for the sweet people who came to listen in the cold because they feel so passionate in this Justice for Damini movement.

May God Bless Damini, may God restore justice in humanity, may God bless womankind.

Afraid to fall-in-love

Those that are afraid do not fall in-love – Pyar Karne Wale Kabhi Darte Nahi

This song is about two people in-love that defy the world.

This world is a terrible place; love is the only thing that gives meaning to our lives.

It is true “those that are (afraid) do not fall in-love” – because falling in-love is a huge undertaking.

All the worlds’ religions are to one aim ~ to unite and promote love. In God’s house there is no Muslim, Christian, Hindu, Sikh, atheist etc. We are all God’s children.

 1 John 3:1  “See what kind of love the Father has given to us, that we should be called children of God; and so we are. The reason why the world does not know us is that it did not know him.

When you are in-love you will willingly and knowingly sacrifice your existence in order to protect your loved one.

I love this quote from the Bible:

Romans 13:8  “Owe no one anything, except to love each other, for the one who loves another has fulfilled the law.

When you are true to your heart the universe bends to your unite you to your love. You need nerves of steel and a heart that will not falter, for God is on your side.

This is my favorite bit of the song (Because it is based on Hindu scriptures of Radha & Khrishna, notice the flute and Minakshi being drawn to Jackie when he plays the flute – I Love it):

Pyar Karne Wale Kabhi Darte Nahi – Lata Mangeshkar & Manh
Movie: Hero (1983)
Singers: Lata Mangeshkar, Manhar Udhas
Music: Laxmikant-Pyarelal

Pass Plus

Pass Plus Scheme for Newly Qualified Drivers

Introduction to the Pass Plus Scheme

First I must say well done you, because if you’re reading this, it most likely means that your have passed your test.

So you may have been presented with the option to take the Pass Plus. I will explain the following:

  • Why you should take the PASS PLUS
  • What you should expect on the PASS PLUS, and the
  • Pass Plus benefit to you

Why you should take the Pass Plus Scheme?

You may be thinking to yourself, “I passed my driving test and I can drive”?

Well that is true you have centrally demonstrated that you meet the level of competence to pass the driving test but what you lack is driving experience.

The Pass Plus is more than just a few extra driving lessons. You are adding to your driving experience under expert supervision and guidance and you will be shown how to deal with driving situations that you may not have confronted whilst learning to drive.

This may include driving in fog, rain, snow and ice, driving in the dark and motorway driving.

After the introduction of the Pass Plus, 17-20 years olds went for being 69.3% to have blame in collision in 1998 to 41.8% in 2002.

That is a 27.5% reduction in total collision for `7-20 year olds and a sure sign that more experience reduces blameworthy crashes.

What to expect on the Pass Plus?

Yu can expect a minimum of 6 hours of tuition of which 5 and half hours will be of in-car driving.

The thing to remember is that some modules may take loner to complete than others and depending on how you are progressing, you may require more sessions.

The Pass Plus Syllabus consists of the following modules:

Module 1 – Town Driving
Module 2 – All Weather Driving
Module 3 – Out of Town Driving & Rural Areas
Module 4 – Night Driving
Module 5 – Dual Carriageways
Module 6 – Motorway

Pass Plus benefits to you?

  • More driving experience under expert supervision
  • Helping you become a more skilful driver
  • Teaching you a develop a positive driving style enjoyable and safe
  • Reducing the risk of you being involved in a road crash
  • Saving you money on your insurance premiums – subject to status, you should check with your insurance company if they offer discounts for pupils who have taken the Pass Plus.

And remember there is no test at the end of the course!
