Playing Computer Games Can Be Good for You

January 29, 2015

The gaming industry is a multi-billion dollar money-maker, as millions of individuals from all over the world play the different games that are developed each year. There have been a lot of studies on the effects of gaming on an individual’s physical and mental health as well as on their effects on the player’s personality. Recent studies have thrown cold water on myths about computer games and their negative effects on the brain. In fact, these studies have shown that video games are good for you.

A lot of studies have shown that video games can improve decision making, creativity and perception. Individuals who play fast-paced action games were found to make decisions up to 25% faster and more accurately than those who did not play any games. In fact, more qualified gamers can make decisions up to six times every second, compared to four times a second for non-gamers. Players who have a lot of computer game experience can concentrate on up to six things at a go without ever getting confused.

Individuals who play simple games can improve their fine motor skills, strategic planning, memory formation and spatial navigation. Life-simulation games can help to improve the flexibility of the player’s brain, and this has been linked to better intelligence. Another study has also revealed that playing computer games can slow down the natural aging process of the brain by stalling the decline of several cognitive skills. Computer games can also increase the attention span of the child, and this is a skill that can be useful in reading.

Another research has also concluded that individuals who play first-person shooting games will have a better contrast sensitivity function. This is an ability to tell the difference between very small changes in the brightness of an image.

Contrast sensitivity function is one of the first visual aptitudes that diminish with age. This ability is considered very crucial for people who want to drive at night or perform other key tasks in the dark. These researchers believe that the process of finding and aiming at the enemies is an exercise for the eyes.

There are a lot of studies that are being conducted to show how computer games can relieve pain or even help in rehabilitation of patients who suffer from grip problems. Researchers have overwhelmingly concluded that video games can be an exercise for the brain, the eyes, and the hands, and that they can have a lot of benefits for the player.

Secrets To Solving Office Chair Pain & Discomfort

January 27, 2015

When your office chair doesn’t have the right functions you find yourself suffering all manner of aches, pains and discomfort.

Do any of the following symptoms worry you?

Your thighs are aching and you have been sitting for barely an hour, particularly the undersides – maybe even some numbness.

No matter what way you sit you can’t find comfort and your buttocks are really uncomfortable, continually shuffling around provides temporary relief, yet it never lasts for long and you soon seem to be back where you started.

Your lower back appears to be in constant pain and you attempt to relieve this by changing position in your chair, the trouble is any relief is temporary and the nagging aches soon return.

Your shoulders and neck are often stiff, rigid even and the lack of movement brings on pain because the muscles supporting these parts of your body are stressed and tired. And this tends to happen almost daily as you work, especially on a tight deadline.

Arms and wrists flag very quickly especially when using a mouse intensively; you are concerned you may end up with RSI (repetitive stress injury) or carpal tunnel problems if it isn’t sorted out soon.

All of the above conditions are all too common for people working with computers regularly and many will put them down to tiredness, stress and pressure of work, which are actually the symptoms of the problems.

What you are sitting on whilst working is highly likely the chief suspect, something which often never crosses sufferer’s minds many of whom never give their office chair a second thought.

By now you are probably wondering how your office chair may be causing some or all of these problems and more importantly what steps you will need to take to minimize these aggravating and debilitating problems.

So let’s begin, it’s time to look at the 5 insights for tackling these issues head on.

Seat Depth Adjustment Is Critical For Good Leg Comfort

Do your legs become uncomfortable in your office chair? Are you finding the underside and or tops of your thighs often ache once you have been sitting for a little while. Are your buttocks frequently uncomfortable too?

Maybe you find you are fidgeting about in your chair because you can’t find a comfortable position to place your legs. You may even suffer with some numbness in your thighs and bottom too.

Cause and Solution

People suffering these symptoms frequently do so as a consequence of their chair’s inability to cater for their leg length.

Seat depth adjustment is a vital requirement for anyone spending any amount of time in an office chair. It allows the seat pad to move in or out adjusting to the perfect setting for your needs. When properly set up your legs should overhang the seat’s front edge by 3 inches or so.

People’s leg length varies enormously, look round any office and observe shorter people perched on the edge of their chair because the seat is far too deep for them. Tall people have the opposite problem they are sitting with their backs pressed hard into their chair back and yet their legs are still overhanging the seat by 6 inches or more.

Correct seat depth adjustment is highly important for good leg comfort and you should always include this function on any office chair you use regularly.

Your chair back must adjust properly supporting your back and spine

Are you suffering a lot of lower back pain sitting in your office chair? Are you finding your chair’s back can’t seem to give you comfortable support? Are you having difficulty or finding it’s just not possible to adjust the back to where you need it to be?

Cause and Solution

If this sounds like you, your chair’s back is the likely culprit, by not adjusting correctly to your back it allows you to sit with a rounded lower back. And this soon causes pain in you back muscles as they struggle to cope with the pressure they are under resulting in them sending you an internal memo called pain.

The commonest cause of this type of pain occurs with a fixed chair back which doesn’t adjust and isn’t aligned with your back or a poorly adjusted or designed chair back.

Any chair having a low or medium height back needs to be adjustable and probably include a little shaping in the back foam to enhance support. With that said avoid chairs with highly sculpted chair backs as invariably they don’t match the shape of your back well and are just as likely to cause you more discomfort as a result.

When you sit in top range chairs they will often have backs that aren’t height adjustable because they tackle lower back support and pain in a different way.

To start with the backs are mostly full height and so will usually properly support your back well as they frequently have a built in adjustable lumbar support which is designed to take care of lower back support correctly.

Others build in lumbar support as part of the overall chair design in such a way they shape to your back dynamically giving good support.

Adjustable arms spread the load on your spine and support arms, shoulders and neck

Are you getting a lot of shoulder pain? Is you neck often feeling stiff and lacking mobility? Are you finding you arms and wrists tire easily and ache, particularly when using your mouse a lot?

Cause and Solution

These sorts of symptoms are often the result of poor arm support whilst working at your computer. Many chairs still come with fixed arms and it just isn’t practical to set them at a universal height which will suit everyone.

As well as this they often have an exaggerated curved shape, maybe because the designer thought it looks cool – reality check.. are our lower arms really shaped like bananas?

Tests show properly supporting your arms can relieve as much as 20 percent of the overall pressure on your spine while sitting. This isn’t perhaps too surprising as your arms, shoulders and head when unsupported act as a considerable dead weight and so put your body under strain.

This problem is best answered by having height adjustable arms and setting them up so they give natural support for your arms, shoulders, neck and head.

When correctly set up your chair’s arms should provide good support for your arms such that your shoulders aren’t straining downwards, or resting in an unnatural upward position like you were shrugging your shoulders.

Some chairs come with additional arm adjustments like armrest angle and forward and backward adjustability. These features can be useful additions, however the most important adjustment is in setting up the height of you chair arms.

Working in an incorrectly height adjusted or fixed chair is bad news for your posture

The effects on your body from working at the wrong height are often similar to those experienced with incorrect seat depth. Are your legs getting uncomfortable in your office chair, feeling heavy or dead? Are you feeling pain in your thighs on the underside or top, numbness maybe? Are your buttocks often uncomfortable too?

Causes and Solution

Many of these problems result from incorrect seat height adjustment. Clearly it’s fair to say the vast majority of swivel office chairs are height adjustable, it may well be the height adjustment range simply isn’t right for you.

The most commonly affected chair users are either short built or very tall built people. When correctly adjusted your feet should be firmly on the floor and your thighs should be at an open angle a little bit beyond 90 degrees.

The simple way to check whether a seat’s height adjustment is right for you is to measure from the floor to the inside of your knee joint without shoes on. Then check the chair will adjust a little up or down from this measurement.

Many better quality chair manufacturers offer alternative sizes of gas lift to enable users who find the standard pneumatic lift isn’t suitable for them to gain the correct seat height setting for their needs.

One final point of caution it’s not a good idea to work at a computer or desk in a fixed height chair like a dining chair. Apart from height issues it will also restrict your body movement and can cause other pain and discomfort problems.

Missing or incorrectly set chair tension to match your weight often causes discomfort

Finding it requires a great effort to move your chair back when you want to recline? I’m guessing you are lightly built.

Seem like your chair loses all control when you want to recline in your chair, offering little or no resistance and suddenly lurching backwards? Chances are you are well built.

Causes and Solution

Both of these problems are caused by the same missing or incorrectly adjusted function on your office chair, here’s what’s happening.

Where your chair omits this function what you end up with is the manufacturer’s best guess at what the back pressure should be set to, not very satisfactory. Quite simply they set the tension to a non adjustable pressure likely to make the chair usable by the most users.

There is simply no way of changing this you’ve got what you’ve got and the only solution is to replace the chair.

You might be lucky and find you have this adjustment on your chair, it could just be poorly setup. How can you tell? Take a look underneath the chair and see if there is round cylindrical knob fitted centrally to the front underside of the chair.

Usually turning the knob clockwise will increase the back pressure resistance, so if your chair has been throwing you all over the place this is the adjustment you should make.

Turning it anti-clockwise will normally reduce the back pressure and so if you have been fighting your chair when reclining this is the direction you need to turn the knob.

Begin by turning the knob gradually and keep trying the chair until you get it set right, you’ll know when you have things set correctly because it will be pretty easy to recline safely.

This type of tension adjustment has been around for many years as is commonly referred to as knee tilt or synchro, it has some drawbacks but it’s a lot better than having a chair without tension control.

A number of the major manufacturers of top quality office seating have moved on from this type of mechanism and introduced more sophisticated and innovative methods of tension adjustment.

There has been a move by some to introduce chair mechanisms which automatically adjust to the sitter’s body weight thus taking the guesswork out of setting up the chair’s tension setting.

It’s important to make sure any office chair you consider buying includes some form of tension control to allow you to recline in comfort and remain in control of your chair.

Here’s a quick resume of the 5 key functions you must insist on having on any office chair.

Seat Depth Adjustment – It’s Critical For Good Leg Comfort

Chairs back must adjust to correctly support your back and spine

Height adjustable arms spread the load and support your arms, shoulders and neck

Correctly adjusted seat height – working at the wrong height is bad news for your posture

Chair tilt tension that doesn’t match your weight often causes needless frustration and discomfort.

Evolution Of Computer Technology

January 23, 2015

Today computers are an indispensable part of the lives of human beings but at one point of time there were no computers. Knowing the history of computers and how much progress has been made can aid us in understanding just how complicated the invention of the computer really is. Unlike other devices, the computer is the one invention that does not have any one specific inventor. Throughout the development of the computer, various people have made contributions to making a computer work. Some of these inventions were those of complete computers or other additions that helped revolutionize the computer that existed at that time. One such invention was the Integrated Circuit.

The single most important year in the history of computers is 1936. It was in 1936 that the very first computer was created by Konrad Zuse who called it the Z1 Computer. This was the first system that was fully programmable. Even though there had been devices that had come and gone before this but they didnt match upto it because of its superior computing power. Till 1942 no business saw profits and opportunities in computers. The first computer company was called ABC computers and was owned and operated by Clifford Berry and John Atanasoff. Two years later in 1942 came the Harvard Mark I computer which furthered the science of computing even more.

The age of computers saw its biggest change ever in 1953 with the introduction of International Business Machines known today as IBM. The company has always been a key player in the development of new systems. This was the first real competition to bee seen in the world of computing and helped to encourage faster development of better computers. The first contribution of IBM was the IBM 701 EDPM Computer. A year after this the first high level programming language was brought to the centre stage. This was a programming language that had not been written in ‘assembly’ or binary languages and was called FORTRAN which was written to enable more people to be able to program computers. In the year 1955 Bank of America, Stanford Research Institute and General Electric joined hands to introduce the very first computer for use in banks.

After that the evolution was quick. Computers like Apple I and II, The Scelbi, Mark-8 Altair, TRS-80, the Commodore Pet computers and IBM 5100 were the leaders of the sector of home computing. The micro processor was like the heart of the computer and began with the Intel 4004. from then it has evolved into todays Pentium IV, Dual core and Core 2 Duo processors. Along with the evolution in Hardware came the evolution in software which went from assembly languages to todays languages like C++, Java and PHP. There is more to come in this field and that more will surely be AI or Artificial Intelligence. The term was coined by John McCarthy and is today a major field of study.

Tips to Move the MCITP Certification Very First Time Round

January 20, 2015

Microsoft is usually a famous certification seller. Well
known with companies and highly esteemed among the I.T local community,
Microsoft certifications are unquestionably not the easiest to move. You
actually do should know your things for these examinations; if not you
might close up failing repeatedly yet again. Here are a handful of
education procedures which will hopefully make it easier to go.

Passing the MCITP or any Microsoft certification is
about operating incredibly hard in your revision. Examining a guide upon
the topic on your own works for some men and women, although not
everyone. Nonetheless, looking through on the subject may be element of
the revision program, relatively than the only strategy.

Tip 1:
You will need to devise a revision approach that suits you. Examining,
producing, generating diagrams, making use of PC primarily based
education and even recording you are often useful in discovering the
things. Constantly try out to get started on by studying the essential
principles then expanding upon them – this is certainly handy for
producing back links in the intellect – enabling you to definitely
remember the information much easier.

Tip 2: Be sure you realize
the knowledge, instead than simply try to remember it. This could
enable you to response tough issues about the examination paper which
can have been entirely rephrased. Never just study the details both, try
to be familiar with the principles at the rear of them. It will provide
you with a significantly broader understanding of why it occurs,
relatively than simply ‘the what’.

Tip 3: To even more your
research into your ‘what’s’ and ‘whys’ behind the concepts undergo them
on your computer system. Essentially bodies do the tasks, to make sure
that you don’t simply understand it theoretically but in practice far
too?

Tip 4: Get firmly acquainted using the jargon and acronyms.
Nobody having a Microsoft examination can anticipate moving with no
figuring out the jargon or the acronyms. Failing to master that is
likely to lead for you fail the exam.

Tip 5: Exam you above and
over once more making use of a revision manual, online assessments or
personal computer primarily based teaching. Just about every time appear
at just everything you bought mistaken and why. You could then move on
to correcting your faults and improve your score each individual time.


Tip 6: Within the precise examination read through the inquiries two
times via comprehensively. This is certainly critical, as otherwise you
might forget a small element which could have substantial impact on the
outcome/answer.

Tip 7: Use what you know to ascertain the
incorrect responses in every query. Discovering the incorrect reply
first can assist you deciphers and that is the best one particular.


Tip 8: Glimpse with the total circumstance in each question, as one
compact but seemingly insignificant detail could impact the answer.
Also, attempt to often have got a crystal clear photograph inside your
brain of what will work while in the provided state of affairs and what
does not; it might enable you to locate the remedy.

Tip 9: Even
though a technical and expertise centered test, Microsoft certifications
do usually search for the very best option almost, alternatively than
technically. Normally continue to keep this in your mind, mainly because
it could assistance not just your revision but could assist you to move
the examination.

Tip 10: Glimpse in the language they use while
in the inquiries. Some inquiries often trick all those becoming
examined by utilizing vaguer language. For instance, quite a few I.T
experts have discovered the ‘what satisfies the required’ issues quite
possibly the most misinterpret query by people getting Microsoft tests.

Resists The Network Attack With The Linux System Firewall Function

January 18, 2015

The hypothesized main engine service provider will possibly come under the hacker attack in the operation process, the common forms of defensive action will have SYN, DDOS and so on. Through replaces IP, searches the stand which attacks is possibly avoided attacks, but interrupt servicing’s time comparison is long. Acquires the hardware firewall compared with the thorough solution. However, the hardware firewall price is quite expensive. May consider that provides the firewall function using the Linux system itself to defend.

1. Resists SYN
The SYN attack is the principle which 3 times shakes hand using the TCP/IP agreement, transmits the massive establishment connection the network package, but is not practical establishes the connection, causes to attack finally server’s network formation to fully occupy, is unable by the normal user visit.
The Linux essence has provided the certain SYN related disposition, with order:
sysctl – a | grep syn
Sees:
net.ipv4.tcp_max_syn_backlog = 1024
net.ipv4.tcp_syncookies = 0
net.ipv4.tcp_synack_retries = 5
net.ipv4.tcp_syn_retries = 5

tcp_max_syn_backlog is the SYN formation’s length, tcp_syncookies is a switch, whether to open SYN the Cookie function, this function may prevent the part SYN attack. tcp_synack_retries and tcp_syn_retries define SYN to try the number of times again.

Increases the SYN queue size to be possible to hold the more waiting connections the network connections number, opens SYN the Cookie function to be possible to prevent the part SYN attack, reduces tries the number of times also to have certain effect again.

Adjusts the above establishment the method is:
Increases the SYN queue size to 2048:
sysctl – w net.ipv4.tcp_max_syn_backlog=2048
Opens SYN the COOKIE function:
sysctl – w net.ipv4.tcp_syncookies=1
Reduces tries the number of times again:
sysctl – w net.ipv4.tcp_synack_retries=3
sysctl – w net.ipv4.tcp_syn_retries=3

Restarts for the system moves when maintains the above disposition, may join the above order to the /etc/rc.d/rc.local document.

2. Resists DDOS
DDOS, distributional refuses to visit the attack, is refers to the hacker to organize from different origin many main engines, to common port, like 80,25 and so on transmission massive connections, but these client sides only establish the connection, is not the normal visit. Because the general Apache disposition accepts the connection number limitedly (usually is 256), these the vacation the visit will fully occupy Apache, the normal visit will be unable to carry on.

Linux provided has called ipchains the firewall tool, might shield from specific IP or the IP address section to the specific port’s connection. Uses ipchains to resist DDOS, is first through the netstat order discovery attack origin address, then orders with ipchains to block the attack. Discovered that blocks one.

Computer Peripherals Hardware – The Parts of a Computer System

January 16, 2015

To start, let us define the difference between computer hardware
and computer software. While computer hardware are physical items also
known as computer hardware components, hardware devices or even just
computer parts, they are all parts of a computer that physically make up
a computer system.

Software on the other hand is not a physical
item, and is only a program written as instructions for hardware to
follow. One simple example of this is used referring to yourself, a
grocery list and a pencil. Imagine that you are a hardware device, the
pencil is a dvd/cd writer, the piece of paper the list is written on is a
disc. All of these are physical items and are referred to as hardware,
The software here is the contents of the list itself, It is not a
physical item, only written instructions on what is needed.

Now,
breaking down the different hardware names (terms), we have computer
hardware devices which are basically a piece of computer hardware that
is designed for a simple specific purpose such as a floppy drive or
mouse. Another name also referred to while discussing computer parts
hardware is the computer hardware components. Computer hardware
components are the single hardware parts that make up the whole computer
system, such as the motherboard, processor or hard drive.

We also have peripherals hardware, which is similar to
the hardware device with the exception that the peripherals hardware is
an addition or an extension of the computer system, such as the
printer, speakers or a digital camera. The word hardware originated from
the construction industry years ago referring to the nuts and bolts
used to increase the strength of the building materials being used and
the term was coined for the computer systems describing the physical
make up of the entire computer system.

Get The Latest Tech Information From Engineering Weblogs

January 14, 2015

Web
websites like the San Francisco Chronicle, CNN, MSNBC as properly as
the BBC all have webpages with tech sections which are updated a number
of instances every single day.

Following
in the footsteps of the main news businesses, the Web giants are also
hoping to cover technologies news. Websites like Google News and Yahoo
News now have fulltime journalists on the conquer and they regularly
break stories that the other internet web sites skip. This is a case of
companies making so considerably income and obtaining only little
thought of just what to do with it, so they commence their quite
personal media service.

1st off, the term weblog is the shortened
“world wide web log.” Most of the time, this is preserved by a person or
