The technology army

Want to do your bit for your country? Join the forces and fight for your freedom? Many people do.

However, wouldn’t it be so much better if you could do it from a comfy chair, in a climate controlled building, with tea and biscuits on hand?

The front line

When you think of the front line, you usually think of solders in action, often in hostile, dangerous conditions. However in our new ‘cyber’ world, the front line is more the back offices. More and more, the threats to our security are not physical, but cyber.

This is why the UK government have set up Cyber Security Challenge UK. Cyber Security Challenge UK is a project that hopes to encourage individuals into the security industry.

Imagine what would happen if the banking system got hacked. Everyone’s theoretical money could potentially be wiped, and we would have no clue who owned what. Imagine a leading brand had a virus infect their entire internal network.

Cyber threats are becoming more and more real, and more and more scary.

If you think that you could be up to the challenge to become a ‘security champion’ head over to cybersecuritychallenge.org.uk and have a go at their challenges.


The challenges are a series of online games and competitions to test your cyber security abilities, to see if you could train to become a defender of computers.

If you are successful, you may be offered a job or funded through training, so it’s worth a try – you never know, you may discover some hidden potential!

Could you work for an anti-virus firm or the government to protect people against cyber crime/attacks?

Why do printer cartridges have chips?

Why Do Ink Cartridges Have Chips?Many of you reading this blog will have a printer next to you as you read this and you will also have probably bought an ink cartridge at some point. But have you ever wondered why a lot of modern printer cartridges have chips?

Well first of all let’s have a look into what types of cartridges have smart chips. There are two types of cartridges: Ink Tanks and Ink Cartridges.

Ink tanks are those that just there to hold the ink, they don’t usually have any circuitry, they just plug into your printer and the ink gets fed to a print-head. Ink cartridges usually have a print-head built in and are sort of the ‘all-in-one’ of the printer world.

It is the printer cartridges that have print-heads built in that usually have chips or circuitry on them. They do so for a number of reasons…

Printer Cartridge Smart ChipPrimarily in this type of cartridge they are used so that the printer can communicate with the built in print-head and are necessary for the printer to work. As well as this they communicate other things to the printer such as ink levels.

This is were a lot of people run into trouble, it can be very frustrating when your printer starts telling you that the ink levels are low but in fact you know that there’s still some juice left in there! This is due to the fact that the cartridge doesn’t actually know how much ink is in the cartridge, it just counts down how many pages you have printed.

Another way the chip is used is to, in some cases, stop the cartridge being re-filled by third party companies. Some manufacturers just simply don’t like people re-using their cartridges as this usually means a loss for them, so once one of their cartridges runs out of ink, the cartridge will remember that it has no ink in even if it has been re-filled.

So that little chip on the bottom of your cartridge does a lot really… both good and bad. If you wish to learn more about printers and ink have a look at the blog of the firm I work for, which can be found on our printer cartridge site.

Tesco launches supermarket sat nav

Ever got lost in a supermarket? If so Tesco have now come to the rescue!

If you can’t seem to find those baked beans, you could soon be able to use a sat nav to help! Yes it’s the same sort of technology that you have in your car but it comes in the form of a smartphone.

Currently Tesco are trialing a new app for Google Android powered smartphones which allows you to enter your shopping list and then the phone will give you directions to the isle and shelf that you can find your items in. Pretty impressive huh?

Tesco LogoThe idea is that it saves you time, meaning you can be in and out much faster. This could make supermarkets less crowded in the future, which could mean less space is needed for people and more for food and other goods.

One of the key ways in which supermarkets like Tesco and Asda make their money however is when people spot products on the way to finding their next item. Often ‘special offer’ products will be placed in areas of the shop that you are bound to walk past and notice.

This behavior from the supermarkets has left some critics believing that supermarkets may program the device to take the ‘scenic route’ in order to get you to buy more, rather than get out quicker.

If you live in Essex, Tesco’s Extra stores in the area are currently trialing the system, so be sure to check it out and leave us a comment 🙂


Because the application is still under development, you have to apply to a testing group to be able to try out the new technology. Soon however, if the service proves successful, Tesco hope to role it out in all of its stores and on multiple platforms – Blackberry and iPhone being the next most obvious systems.

What do you think, could this really improve your shopping experience, or is the way forward online shopping anyway?
