What Is Hacking?
What is your definition of hacking? Most people think of the news stories that relate to big companies having embarrassing problems as their data is compromised. But in truth, hacking goes a lot further than this.
It doesnt always have to be someone you dont know who hacks into your systems and causes problems for your business. It could equally be someone who works for you that doesnt have your best interests at heart. This is because the basic meaning of hacking is when someone accesses some or all of your computer systems without permission. And it doesnt just happen over the internet.
Quite often, many people dont see how widespread computer hacking can be. Assuming that they are only in danger from internet based attacks means they may not be covered for all risks. Even those companies that do all they can to prevent hacking which occurs online may have unwittingly turned a blind eye to other dangers.
This is why an understanding of what hacking is and what it involves can help you to protect your own business more fully. But what do you do if you dont know all the ins and outs of the threats posed?
The easiest solution is to rely on an expert to make sure every potential hole is plugged, and no one can break into your systems. Network penetration testing is one of the best ways to see how good your computer network really is. If you do have vulnerabilities its best to find out via someone who is honest and is looking for them to benefit you. If you assume everything is okay and it isnt, you could be in for a nasty shock at some point in the future.
It is probably because people limit their definition of hacking that some businesses are more in danger than they realise. Everyone likes to think that all their employees are working honestly and for the companys good, but it doesnt always pan out that way.
Supposing an employee was given notice to leave but they had until the end of the day to clear their desk. They could potentially do a lot of damage to your computer system before they left, if the mood took them that way. Even though you could have them arrested for their actions, the damage would still be done and it would take time to rectify.
An expert in the field of ethical hacking would be able to highlight any potential problems and solve them before anyone else had a chance to exploit them. And that is certainly a service that is worth paying for.
Dont make the mistake of thinking this should only be done once though. Hackers are constantly finding new ways into previously secure systems. If you employ a company to see how up to date your security measures really are, make sure you do it on a regular basis. If you dont, you still run the risk of being caught out.

Air Cylinders and Pneumatic Systems: Making Things Work
Have been affected by pneumatics today? What a silly question. Of course you have! You just didnt know it. In fact, pneumatics have much more of an impact on your life than you might think. First, what are they?
The term “pneumatics is typically used to refer to a branch of technology used almost exclusively in the industrial sector to control machinery. While there are a number of ways to control various types of machinery, one of the most effective, efficient, and most popular methods is through pneumatics.
Pneumatic systems make use of canisters of compressed air or specialized gasses to then exert a force on a wide array of pistons and machine parts. These pistons and components then provide the necessary movement required by the machine to accomplish its given task.
While the possibilities are vast when it comes to operating any type of system, Pneumatic systems are one of the simplest methods which in turn makes them one of the most prevalent as well.
Pneumatic systems are comprised of a few major parts. First, theres the compressor. The compressor is a pump that compresses air, raises it to a higher pressure, and then delivers it into the actual pneumatic system. This process can also be used to generate a force that pulls (a vacuum) instead of a force that pushes.
Next, there is the check valve and the directional valve. A check valve is a one-way valve that is used to grant the pressurized air access to the pneumatic system while at the same time preventing backflow. The directional valve actively controls the direction of the airflow to its correct source.
You might ask, “What happens if too much air is permitted into the system?” For that there is the accumulator, which stores compressed air to prevent potentially dangerous surges in pressure while also ensuring efficient operation.
Finally, theres the actuator. Pneumatic actuators convert the stored compressed air into actual mechanical motion. Typical pneumatic actuators are comprised of a piston, a cylinder, and a configuration of valves and ports. In pneumatic systems, the motion created by the actuator is usually rotary or linear.
Pneumatics make quite a few things possible. While you might not realize it, they actually have a profound impact on our every day lives. For example, pneumatic systems are frequently used in
- Air brakes on busses and trucks
- Air compressors
- Pneumatic air guns
- Pneumatic mail systems
- Pneumatic motors
- Jackhammers
- Nail guns
- Pressure regulators
- Vacuum pumps
- And much more
So as you can see, from mass production and manufacturing to the jackhammers that fix your roads and the busses that drive on them pneumatics have a pronounced impact in a number of ways.
