How to be a smart online buyer

20 Replies Christopher Roberts

When you decide you want to buy something off the internet, how do you go about doing so? I’m not talking about getting your shopping delivered to your door, I am talking about buying something like maybe a laptop, digital camera or a new mobile phone.

Many people just look for the make and model they want and they go straight in for the buy. Do you? If so, you may want to read on, as you could save yourself a lot of money!

Say I wanted to buy a laptop, one of the first things I would do would be to go to a money saving site like Money Saving Expert in order to establish whether there are currently any great offers on laptops that other people on the web have noticed.

If you are still looking for the best type of laptop for you, try review and comparison sites like Test Freaks. These can help you decide what laptop to buy, as they can give you reviews that people who have bought laptops have written. They often also present data in a very easy way, often giving the product a score, based on its price, spec (and therefore value for money) and what peoples reviews are like – i.e. positive or negative.

Test Freaks LogoIf/once you have your heart set on a particular laptop, then your next step is to look for discount codes for that sit/product. Sites like My Voucher Codes can often save you 5-10% on your goods, simply because they know the latest discounts for your product. 5-10% might not sound that much, but if you are buying a £350 laptop (lets say $500) 10% is £35/$50 which is enough to buy you a really good travel case as well as a decent wireless laser mouse and a USB hub.

The final bit of advice I would give you is to take your time. When spending a large amount of money over the internet check reviews of the site you are buying off, to see if it is reputable, check that the item is exactly what you want and make sure you get the best price!

Often online sites have deals which change all the time, meaning that tomorrow that perfect laptop may now be 25% cheaper, as it was only higher priced so that they could bring it down and slap a ‘25% off!’ label on it.


Good luck making any online purchases 🙂

Anyone got any other advice/experiences to share?

How do you use comments?

How do you use comments? That’s my question. How do use comments on Technology Bloggers and other blogs, and are you getting the most out of your commenting experience?

In the past Kaushal has written about how to make the most out of blog commenting, and now I am going to do something similar, but in my soft of way.

So let’s focus on comments here first.

When you comment, do you ever take notice of others comments? Well if not you should! Comments often contain the most valuable content of the whole article (as I think I have said before) so it would be wise to read them.

Furthermore, making good use of the ‘Reply’ button is never a bad thing either. Not only does it show that you read others comments, but it also helps to spark conversation and ultimately relationships within the community.

The next thing to remember is that I don’t like to leave useless stuff lying around cluttering the place up. Hopefully this shows in the design of the blog, especially the comment field. This brings me onto my next point, make use of the information the blogger has given you.

Technology Bloggers Comment Form

Technology Bloggers comment form - found at the bottom of every article, and where you go to leave your contribution

Take a look at it, and you should see that it is busy, but not cluttered. Everything there is essential and telling you something.

The “we are a dofollow blog” bit tells you that you get ‘extra rewards’ for commenting here if you have a URL; the “check out the comment policy” bit lets you know that we have rules and values, and they are on show for all to see; each of the comment fields has its name and a brief description, to help you put the right thing in each box; below the post comment button is an anti-spam box, showing that we must care about your comments, and finally the CommentLuv box is there to help you squeeze the most out of your contribution.

Make use of this information, it is there to help you write the best possible comment!

What you can now do is apply this when you comment on other blogs. Okay, they may have slightly different systems and ways of doing things, but at the end of the day, they are all just helping you add your contribution.

Comment are very important, and that’s probably why I keep writing about them! Why not add a contribution now, either as a new comment or in reply so someone else’s below and demonstrate your knowledge of how to use comments?

Get ready to rewrite the laws of physics!

At the end of last week the news broke that scientists at Cern believed they had managed to send subatomic particles faster than the speed of light! This was big science news, and potentially big technology news in the future, however I choose not to write about the discovery straight away, as I wanted to find out as much as I could before reporting back to you.

What happened?

So what basically happened last week was that scientists in Cern (Switzerland) who have been blasting neutrinos (subatomic particles) 732km all the way to Gran Sasso (Italy) for a good few years now, collated all their data, and found that it would actually appear that the neutrinos arrived at Gran Sasso when light was still 18m away Basically the neutrinos raced light 732km and won by 0.00000006 seconds –  or as you could also say, 60 nanoseconds.

Is this true?

Scientists at Cern would tell you that their research has been checked and double checked, therefore what they have found out is true as they can’t seem to find a flaw in the research. However at the same time, almost any good physicist, and no doubt scientist working on the project would tell you that it can’t be true and that a variable must have been overlooked, as the results are impossible!


To verify the findings, two similar projects one in Hida (Japan) and the other in Chicago (USA) are attempting to recreate the experiment, and should have reliable enough results, hopefully, by some time next year.

Why is this important that the neutrinos travelled faster than the speed of light?

Einstein said that it was impossible to travel faster than the speed of light. If you like, light was the universal speed limit, no faster could anything ever go than light, you could go as fast, but not faster. This would mean that to get to the sun, (not that you would want to) the quickest you could ever do it would be in 8 minutes and 12 seconds.

The Sun

It takes around 8 minutes and 12 seconds for the light from the sun to reach earth

If the results from this experiment are correct, with some extra thrust, it would be possible for the neutrinos to get there even faster than light could.

How have they ‘broken the speed limit’?

You may be wondering how the neutrinos managed to get to Gran Sasso faster than light, and as are many scientists! There are two main theories of how they did it at the moment.

The first theory is that the speed of the neutrinos was so great they were simply able to travel faster than light.

The second, much more interesting theory is that the neutrinos didn’t exceed the speed of light, but instead dimension jumped! This means that they probably didn’t travel faster than the speed of light, just used another dimension to get from Cern to Gran Sasso.

The Doctor's TARDIS

The Doctor’s TARDIS (from Doctor Who) travels in time and space, this is only possible if you can either go faster then the speed of light, or jump dimensions

Physicist Brian Cox has an excellent explanation of how this could potentially work. When talking about extra dimensions he has said that:

“…if they are right, then things can take short cuts through the extra dimensions. It’s just like saying there is a speed limit that stops you going, lets say you go from London to Sidney, so you fly around the earth from London to Sidney, but the other way to do it, is go through digging a big tunnel, straight through the earth and that’s a shortcut. So in some ways, extra dimensions can behave like that, so what could be happening is the neutrinos could be taking a shortcut thorough another dimension.”

If this were right, then Einstein’s theory of special relativity wouldn’t be violated, just only valid in three dimensions.

What next?

The data is now out there on the net, for all scientists to analyse. Also, there are many places that are going to try and replicate the stud, to prove or disprove the results.

Hopefully we will have some more news soon, as to whether we actually can get things to travel faster than the speed of light, and as to whether there are are more than three (four including time) dimensions!

Anyone else slightly excited by this? 😀
