How Do Viruses And Worms Affect Your Computer

Also, unlike viruses that most commonly infect an individual computer, the worms usually attack a computer network. A computer network functions by using a collection of servers and routers. This is what the internet is comprised of. A server is like a PC but has more speed and storage and a router is a server with specialized functions, it directs traffic through the network.
PC Security – Worm Viruses, Deadliest of All

A virus attacks the unit used to run programs on the computer called the central processing unit or CPU for short. It does this by running programs and being constantly busy, so that none of the functions you select can be opened. Similarly, this is how a worm functions on a network. The routers rely on memory and processing time (similar to the CPU functions). These are attacked and as a result the network drastically slows down.

Worms carry payloads which are comprised of other types of malware, backdoor installations or spyware. Spyware is a monitoring program that can keep an eye on activities on your computer and backdoor programs set up hidden access points used by hackers to steal your information or send spam.

My Doom sent out at the beginning of 2004, was the fastest spreading worm to date. The worm came in the form of an email with the message “andy; I’m just doing my job, nothing personal, sorry.”

Although the culprit was never found, its intended victim is thought to have been a software company called Santa Cruz Operation or SCO for short.

When a person opened this email, the worm was programmed to overwhelm SCO’s website with traffic. The worm spread through the internet and caused a massive slow down.

For the individual computer, the worm’s payload is more serious because it allows ports to be opened on the computer where hackers have access to steal or delete information. In addition, a payload may come with a program to attack your antivirus software and disable it.

De worming

Using firewalls will help protect your computer. Firewalls reduce traffic and hide your computer. In this state, you are less likely to be attacked by worms spread over the network.

Be careful not to open suspicious emails and if you don’t know the person or get and unexpected email don’t open it. If you find your computer is slow and reboots by itself or the internet is sluggish, you may have been infected. Try running antivirus software to check it out. If that doesn’t work, try to manually removing the virus. Information as to how this is done can be found on the internet.

Programming Tutorial Android Development; Andengine

Finally Ive been able to check out the Game programming for Android. Ive found several Android game programming tutorials out there, but none of them were really exciting or user friendly. However, I was able to find an open source game engine which makes the life of a programmer a lot easier when it comes to game programming for the Android platform.

Andengine

The Andengine is an open source, free game engine strictly aimed at the Android platform. It offers Physics such as gravity or collision checks to the developer. Its based on OpenGL and offers a lot of functions which make the life of a game developer a lot easier. The advantages of this game engine are that you dont need to mess around with OpenGL directly when programming games for Android. You get some easy to use and fancy classes, so you can develop fast and efficient games in no time! Also this game engine is being developed on right now, so its not like a game engine which is dead and has a low user base. Its very wide spread and there are a lot of apps out there on the Android Market (obviously games) which were programming using the AndEngine. However, there is one problem with this game engine, which will probably scare away a lot of users; the documentation. The game engine might be coded fine and you can view the source code, but there is no or low documentation. There are examples out there for basically anything your game developer heart desires, also there is a community that will be glad to help you out, but there is no Javadoc for example, which is a badly wound for the AndEngine. However, its open source and free, so you cant expect more, its just great!

My own experiences with the Andengine

To be honest I havent had that much experience with the AndEngine. I have just been playing around for a while now with the examples out there and I will soon post some game tutorials in the near future on this blog, so you can get a feeling for the AndEngine. However, it seems that stuff which should be very easy to do, such as loading a picture into the memory, is not that easy using the AndEngine. Let me put it in another way, it is easy and user friendly, but its not very intuitive, you will need to get a feeling for the AndEngine first, if you have been programming with other Game development kits or engines, it has its own special approach. However, the code is very readable and well maintainable. Also the source is very well written and basically anybody with some Java and Android knowledge will be able to understand the source code more or less.

The Importance Of Keeping Accurate Notes In Science

Science is a progressive act. This means that progress in science is a tedious process that requires diligent efforts with respect to record keeping because in the case of every scientist, figuring out everything about a field of study, such as any given sub-niche of chemistry, is impossible, even in a lifetime. Record keeping is of utmost importance and accurate record keeping can and will make the difference between work that is successfully continued by a scientist’s successors and work that is not successfully continued.

In the field of science, all of us stand on the shoulders of giants. In other words, we all learn from our predecessors and build on what they have taught us. However, we are able to learn only from those who have successfully transcribed their knowledge in an accurate and concise fashion so as to facilitate the propagation of the knowledge to those who follow.

Accurate lab notes are a must. Accurate lab notes will have a variety of properties including but not limited to:

An accurate introductory description of the process or processes being studied. For the information following the introduction to be understood in it’s proper context, an accurate introductory description has to be described clearly. Why is this subject of interest? What is the current understanding of the subject and why does it need to be studied further? What questions need to be answered before true progress can be made? All of these question should be covered in the introduction.

Clear and concise methodology. The work that is performed or is to be performed must be clearly spelled out for those reading the notes to understand the important steps to be taken to repeat and confirm the results. Each step must be labeled in detail and must be done so in a way that can be repeated using the notes alone. This is important if results are to be duplicated.

Well documented and understandable results. The results that are discovered by the initial experimenter should also be spelled out in clear detail as they may differ from the results obtained by those following them and trying to repeat their work. If results differ, this should be clearly noted by the scientists attempting to repeat the work and differences in results should also be clearly noted.

Objective conclusions. Conclusions should be recorded and based on evidence and results obtained. If data or results have discrepancies, these should be noted and discussed in the conclusion.

Reasons Why You Should Be Using Forex Automated Robots

Forex automated robots are those which handle every aspect of trading for a currency trader in the forex market from initiating a trade to pulling out when it turns from your favor. The obvious implications are that first time and less experienced or more casual traders can use it to trade in their stead to still see reliable gains come from the market, so let’s take a look at the top 3 reasons for why you should be using forex automated robots.

First, you get 24 hour trading around the clock. Considering that the Forex market takes place over a number of international locations, it’s technically open 24 hours a day during the week. Obviously the key to success in the Forex market is to know the whereabouts of one currency against another that you’re invested in around the clock. Forex automated robots do just that and trade accordingly when they find profitable trading opportunities. Because of this 24-hour nature, the Forex market can be a job and a half, hence the popularity this technology.

Secondly, all trading is emotionless when running Forex automated robots. The major reason why so many traders fail in this market is a lack of discipline. They don’t know when to get in and out of trades, especially the latter, and oftentimes a trader will stay in longer than they should while trying to ride out a trend as long as possible or wanting to recover gains which they did lose in a reversal while they hope for a second reversal.

Finally, and perhaps most obviously, because every aspect of trading is totally carried out for you assuming that’s what you want, it levels out the learning curve so that first-time traders can bring in some modest gains without needing the time or experience as those who’ve done their whole lives.
