Getting Cinema Quality Sound At Home

Wednesday, May 19th, 2010

Do you love going to the movie theater and get lost in the realism that their superior sound systems create? If you do, then I bet you are also one of those people who hates going there, only to have a potentially fantastic evening ruined by irresponsible people talking through the movie or letting their cell phones ring.

I used to love the movie theater, but that was in the time when people respected the rights of others to listen to a movie in silence. There were no crying babies, ringing mobile phones or noisy youths in cinemas and if they got in they were soon kicked out if there was any row.

These days, cinema managers seem to take the easy route of letting these people spoil it for others. Consequently, more and more quiet people are staying at home and the cinemas are getting even noisier. If you are one of the stay-at-homes, but miss the cinema, why not reproduce one in your home?

Build yourself a home cinema with surround sound. You will never be sorry for installing surround sound in your home, because you will be able to play your favourite films, the TV and your music through it. The distinction between surround sound and stereo or even quadraphonics is breath-taking.

Different people have different desires, expectations, funds and even hearing ability, so it is difficult to suggest a system to a mass audience, but there are ways and means for going about the purchase of your own home theater system. A lot of people buy a kit home theater. This is OK, if funds are limited, but you will want to upgrade the screen and the speakers before very long. If you just want to put a home theater in a small spare bedroom and do it quickly and easily, then this approach is for you.

If, however, you want a bit more, then you might prefer to get a bigger screen and make do with the speakers that came with the kit. These can easily be upgraded later. If you want to get everything part by part, you will need a screen, speakers and DVD player. If you would like to play games too, replace the DVD player with an Xbox.

But back to the speakers, whether you are renewing or putting your own system together, the strategy I suggest hold true. Write down the dimensions of your room or better still make a little plan of it to scale. Take this around the shops and malls and try to listen to a few set-ups in a room similar to your own. This could be difficult, but you might be fortunate.

Work out whether you need a 3.1; 4.1; 5.1; 6.1 or even 7.1 set of compatible surround sound speakers. Basically, it all depends on the size of your room, but the shop assistant will be able to show and advise you. As a guideline, a 5.1 surround sound set will be sufficient for most rooms. The figures stand for normal speakers and sub-woofers: ie 5.1 means five normal speakers and one sub-woofer.

The arrangement of the speakers depends on the size and shape of the room and on your personal preference, but the standard layout would be: one speaker the far left and far right of the screen and one underneath it with two more speakers slightly apart from each other at the back of the audience. The sub-woofer can go at the front or the rear.

Free Computer System Security Measures

Tuesday, May 18th, 2010

Today, more and more people are using their computers for everything from communication to online banking and investing to searching. As we do these things on a more frequent basis, we open ourselves to prospective hackers, attackers and crackers.

While some may be looking to phish your personal information and identity for resale, others want to use your computer as a platform from which to attack other unsuspecting targets. Hereunder are a few easy, cost-effective steps you can take to make your computer more secure.

1. Always make backups of important data and store it in a safe place away from your computer.

2. Update and patch your operating system, web browser and software frequently. If you have a Windows operating system, start by going to windowsupdate.microsoft.com and running the update wizard. This program will help you find the latest patches for your Windows operating system. Also go to officeupdate.microsoft.com to locate possible patches for your Microsoft Office programs.

3. Set up a firewall. Without a good firewall, viruses, worms, Trojans, malware and adware can all access your computer from the Internet with no trouble. Consideration should be given to the benefits and differences between hardware and software based firewall programs.

4. Check your browser and email settings for optimum security. Why should you do this? Active-X and JavaScript are often used by hackers to plant malevolent software into your computer. While cookies are relatively harmless in terms of security matters, they can still track your activities on the Internet to build a profile of you. As a minimum precaution, set your security setting for the ?Internet zone? to High, and your ?trusted sites zone? to Medium Low.

5. Install antivirus software and set for automatic updates so that you get the most recent versions.

6. Do not open unknown email attachments. It is simply not enough that you may know the address from which it originates because many viruses can be spread from a well-known address.

7. Do not run software from unidentified origins. Also, do not send these kinds of programs to friends and coworkers because they contain funny or amusing stories or jokes. They may contain a Trojan horse just waiting to infect a computer.

8. Disable hidden filename extensions. By default, the Windows operating system is set to ?hide file extensions for known file types?. Disable this preference so that file extensions show in Windows. Some file extensions will, by default, continue to remain hidden, but you are more likely to see any unusual file extensions that do not belong.

9. Turn off your computer and disconnect from the network when not using the computer. A hacker can not attack your computer if you are disconnected from the network or the computer is off.

10. Make a boot disk on a floppy disk or CD in case your computer is damaged or infected by a malevolent program. Clearly, you have to take this precaution before you are subject to a hostile violation of your system security.

Why Get A See-through Computer Casing?

Sunday, May 16th, 2010

What is a clear computer case and what can it do for you? Well, before we start talking about the transparent computer casing, permit me to inquire you something: what does your computer?s case signify to you? I can even ask: what does your computer signify to you? I ask this as your answer will establish what you want for your computer and its housing or case.

Most individuals have always been happy enough with the simple, average light-grey housing that comes as bog-standard with the preponderance of computers. A few have never even had a second thought about it. But at the same time there are others who have thought about their computer?s case a lot and who would like something individual for their computer.

A number of of these people were skillful at metalwork, others at woodwork and a few at glassware and there are a number of truly fantastic, futuristic, homemade cases out there. Principally among the gaming community. However, we are not all so talented with our hands, but that does not signify that we have to be stuck with the grey computer housing.

The easiest option, if you want a custom computer case is to create one out of acrylic – the sort of substance used to make most fish tanks. You can purchase and easily cut sheets of acrylic for the sides and glue them all together with acrylic resin. That may appear hard, but it really is not. Initially you would have to research the architecture of a typical computer casing and then just reproduce it in acrylic. You could make a translucent computer housing in a weekend.

Or you could buy a translucent computer casing kit. These kits come in flat-packs just like most kitchen fittings and can be easily assembled according to the instructions with a screwdriver. No cutting, no measuring, just a little gentle screwing.

And I signify gentle, as the screws that come with the translucent computer housing packs are more often than not made of acrylic as well and will break easily. It is the only section of the assembly process that requires a admonitory note, as you don?t want to have to drill out a broken screw, do you? That would only put a dampener on your fun.

So why would anyone want a clear computer housing? I imagine that there are loads of reasons. Some people may just want to be different and others may want to show that they can assemble or even create such a case. However, the see-through computer casing also has artistic and practical advantages. At least the good ones do.

On the Aesthetic Front: enthusiasts add neon lights and small LEDs that twinkle on and off or just glow eerily, perhaps activated by some occurrence, like a hard drive coming to life. These displays are called ?themes? and are typically red or blue, but can be almost any imaginable colour. Then you can include coloured fans (or paint your existing ones). You already have at least one fan in your casing and probably two or three.

On the Practical Front: lots of people like to see what is happening inside their computer housing and it is neither realistic nor safe to remove the cover all together. Moreover, making your own transparent computer housing allows you to include more fans as over-heating is the prime cause of hardware malfunction. The more fans the better.

A translucent computer casing would also permit you to see whether a fan has failed, which would result in over-heating in a normal casing and certain hardware malfunction, whereas you would notice it happening through your clear computer case and substitute the fan before major injury and loss of data can happen.

Home Theater Packages

Saturday, May 15th, 2010

If you want to get a home theater system, there are a few essential principles that you should keep in mind. However, no matter how much advice you are given, if your level of know-how is insufficient to understand it, it is useless. Therefore, you have to be honest with yourself and admit to yourself how much you know.

Fortunately for most of us, the Baby Boomers are the most electronically wise older generation ever, because many of today’s older generation grew up in the 70’s when everyone had a TV and a stereo.

Music and sound quality is important to Baby Boomers. However, if you were one of those who was not interested in electronics, a home theater package is probably for you. On the other hand, if you feel competent to take on the task, you will be better served by a system that you compile yourself.

This is not to say that kits are not much good, it is just that there are several variables that must be taken into account before purchasing a home theater system.

Sound or acoustics depends on the measurements of the room where the home theater system is installed, most of us realize that, but because we are unlikely to want to remodel the room to suit the theater, we have to select a speaker system to suit the room.

Likewise with the screen. Bigger is not always better. There is a ratio that can be used to help you work out the size of the screen you should be thinking about, but even this proportion depends on individual predilection.

The formula says that you should sit 9-15 feet away from a 36 inch screen, but you may have weak eyesight and prefer to have a 48 inch screen. This is where kit fall down.

In general, home theater packages suit regular shaped, smallish rooms. By that, I mean 12 – 20 feet in length and combinations thereof. Then, depending on the room again, you will have to consider the sound system. Stereo is not up to the job, if you want to replicate the sound of a full size movie theater. In order to do that, you will need surround sound with at least three speakers and probably five or more.

All in all, you will get the best system for your home movie theater if you buy the components separately, especially if you have an odd or oblong shaped room or certain personal preferences. However, a standard package delivers a quick and easy, passable solution for many modern, ’standard’ sized rooms.

One last piece of advice though, if you do buy a kit, make sure it is one that you can upgrade, particularly in the sound department. A TV screen is just a matter of a connection and they are all the same, but if your home theater package comes with three or five speakers, maybe you will want to add some more one day. You may also want to think about adding games functionality to your system too.
