Data Encryption in USB Sticks

The use of encryption has been around for years in one form or another and even dates back to the hieroglyphics of ancient Egypt. However, perhaps the most famous historical use of encryption happened during the Second World War when Germany used the mighty Enigma machine to code their highly sensitive military plans and strategies transmitted across Europe and the world.

Data encryption in the modern world still follows the same basic principle, that being the systematic scrambling of data in order to make it unrecognizable to anyone who does not know how to un-scramble it. In computer speak; it is the conversion of plaintext into ciphertext by use of an algorithmic cipher. In addition, a simple definition of an algorithm would be a detailed set of instructions that lead from a known start to a successful finish.

Whilst this all might sound a little high-tech, the fundamental message is clear; without the cipher, encrypted data will mean nothing to anyone trying to read it.

Encryption in today’s world is of major importance. With sensitive information of a personal, commercial and public nature increasingly stored and transmitted electronically, securing it from the prying eyes of opportunists or hackers should be a priority.

From a business aspect, there are many areas where the encryption of information should be considered. For a start, the records, and personal details of staff need to be secure and likewise the details of a company’s customers could be a valuable asset to a competitor.

Financial information, details of important deals, and plans for the future strategy of a company are all examples of sensitive information. A simple rule would be to encrypt any information that could be detrimental to the business if it were to get into unauthorised hands.

The value of encryption becomes even higher when it comes to portable devices. Losing a laptop or a USB stick that isn’t encrypted opens the door for anybody finding one.

In recent times, some manufacturers of USB sticks have produced units with encryption hardware built-in however, there are also a number of third-party software products available for those without, many of them as free downloads such as TrueCrypt, FreeOTFE, and Cryptainer. A Google search will reveal many more.

Electronic data is valuable and like all valuables should be kept safe. Modern technology has made it possible for information to be transmitted quickly and stored in vast volumes, but it has also made it possible to safeguard it. Businesses will only have themselves to blame if their information gets into the hands of unauthorised people.

Builders Tips – Fix Cupboards

BUILT-IN CUPBOARDS

Nearly every residence has some built-in cupboards and often we want more of them! Whether inside the kitchen, bedroom or bathroom, they’re usually in fairly constant use and so suffer the exact same wear and tear troubles suffered by doors and windows. Kitchen cupboards in particular break from constant opening and closing and being in contact with water and heat.

Built-in cupboards could be one of the additional expensive things to call a tradesperson in to build. There are some jobs the average DIYer can do around the house to fix up difficulties and update the look of their built-ins. Kitchen cupboard doors no longer line up over time, cupboard doors tends to sag, particularly the ones that get used all the time. About once a year I need to take a screwdriver to the cupboard door hinges and fine-tune them to be able to keep the doors aligned.

Most doors are designed to be adjusted rapidly and very easily with nothing more than a screwdriver, as most kitchens built inside the last 30 years or so have concealed, adjustable hinges. Usually these hinges have four adjusting screws, allowing you to make three main adjustments:
Lateral – the front grub screw (or set screw) adjustment permits the door to be moved side to side.
Depth – loosening the back screw enables the door to be moved in or out.
Vertical – the two top and bottom screws enable for adjustment of the door in an up or down direction.

You’ll have to experiment with the readjusting to acquire ideal alignment, but you will soon get the hang of it. It’s worth noting that most of these types of hinges are manufactured in Europe and will in all probability have Pozidriv screws in them.

Fixing sagging corner cupboard doors
The problem with built-in kitchens is the corner cupboard, It constantly ends up a black hole where you can’t find anything that’s pushed up the back, and the doors, being double Sectioned, usually sag and eventually fall off. This kind of hinged door is a lot heavier than your normal cupboard door, as the hinges on the cabinet and holds the combined weight of both doors, In order to counter this extra weight and open the gap between the top of the folding door as well as the adjacent door, you must compensate by over adjusting not only the hinges that attach the doors to the cabinet but also the hinges that join the two doors together. Both hinges will have an adjustment screw that fits via a slotted hole, usually at the back of the hinge assembly. Loosen this screw slightly and then push the two parts of the hinge closer together just before re-tightening. It could possibly take a couple of attempts to get the doors to sit where you would like them.

Fixing drawers
Just like the rollers on sliding doors, rollers on drawer runners can get worn or damaged. Replacing the inexpensive runners or slides will have the drawers rolling like new again and is really a fairly straightforward operation:
1 – Pull the drawer forward and lift the front to remove it from the cabinet. This will give you access to both parts of the roller assembly.
2 – Removing just a couple of screws will totally free up the old mechanism. Once again, a decent hardware store should have an exact matching assembly; if not, try cabinetmakers supplies in the phonebook.
3 – These are commonly sold in pairs and you must replace both sides of your drawer at once. You will only want a screwdriver to replace the old screws into the original screw holes.

Sometimes with excess pulling and over loaded drawers (or perhaps if the runners had been broken), drawer front can turn out to be loose and pull away from the rest of the drawer. If this is happening to yours:
1 – Remove the drawers and clamp the front back into position.
2 – Add some tiny metal 90 degree angle brackets to the inside of the drawer prior to it comes apart entirely.
Another common complaint is the collapse of the thin baseboard inside the drawer. This will normally take place for the reason that the drawer has been overloaded.
