Selling Your Computer 3478

Unless the activities on your computer are restricted to pure textual output (plain text files), your computer is going to get filled with a lot of "stuff" - stuff that can overfill a PC's capacity too much for the computer to function well.

The problem is that while upgrading a computer is always an option, technology advances so fast that newer products (such as memory chips, new drives, etc.) aren't always compatible with the machines that we own. Sure, one could upgrade the operating system to accommodate the demands of a new piece of hardware, but trouble starts when that new operating system requires new hardware in return. Today's "older" computers are perfectly capable of accommodating the needs of young PC users, and they're excellent machines for playing educational CDs, small multimedia files, or games downloaded from the Internet.   Convert the machine into a storage area. As you can see, old computers still serve a purpose either for you or for someone else. And although selling an old computer is always an option, there are a number of things that you can do with an old computer. The one huge concern for many when it comes to selling a computer it what happens to the data on the machine. Find out what you can do to protect your old data.

You can reformat the drive. . This way it's harder to find the old data if not making it impossible.
. It will delete a file permanently instead of leaving traces of it on the drive.


What's the craze all about?

If you haven't detected of smartphones, we'd like to learn where you have been concealing all now. Smartphones have been all over the news and chances are high that, you do know what they're - only you recognize them underneath a special name. Smartphones are mobile phones with pc like capabilities.

What's that? Aha! affirmative, you've not only detected of them, you have in all probability seen them further. packed with internet access, email capabilities, address books, and a full lot more, cell phones have come back a long manner since their first debut. but be careful not to confuse these newest toys with sandbox devices.

Sandbox devices are tools that come back pre-loaded with things like calendars, calculators, and a notepad. What differentiates them from smartphones is that users can add (download and install) further programs to smartphones and they apparently become mini transportable computers for the people who use them. That - and also the ability to edit the content that sits on them - is what makes these phones "smart." 

Some of the more common brand names embrace the Blackberry, PalmSource, Nokia, and Windows Ce. yet the craze is extending to even some off-brand company names. Today, it's hard to search out a telephone that doesn't offer some style of "smart" technology as a result of it's in such a high demand. The convenience of getting information at our immediate access is fantastic - such a lot so thousands of programmers have jumped on the chance to create distinctive applications specific to these little machines.

As a result, you'll be able to notice tons of games, databases, grade point average systems, weather reportage programs, and even little encyclopedias on this stuff - each accessible not at the clicking of a mouse - but at a number of presses of a free thumb. of course a mini keyboard is obtainable for the text-messaging fan or for the poor fellow World Health Organization can't appear to urge aloof from the office. in the latter case, do not be shocked if you discover the entire Microsoft office suite displayed at intervals a screen no larger than a matchbook.

Is this a phase? that's highly uncertain. The market for these devices extends from the highly technical and skilled all the way to the pre-teen personage. the product crosses all demographics and thanks to decreasing prices - it sees no economic boundaries further. The Wikipedia encyclopedia claims that "Out of one billion camera phones to be shipped in 2008, Smartphones, the higher finish of the market with full email support, will represent about 100 pc of the market or about a hundred million units."

But what's it that creates smartphones therefore appealing? As mentioned, smartphones offer US the power to not only carry our information around with US where ever we have a tendency to go, it also provides US the power to edit that information anywhere - any time. In today's "reality" primarily based generation, we're continually searching for the chance to capture and live over a flash. and we want to share that moment with others. At best, good phones offer US the chance to express ourselves impromptu with diverting results.

Attempting to try and do constant with a bulky PC or laptop computer is to cumbersome. Even some of the littlest peripherals (digicams, digital cameras, etc.) do not offer US constant opportunities that good phones do. having the ability to carry around a device for communication, creation, recording, and written material simply compliments the requirement for today's generation to try and do more and then have it away, faster!

Smartphone Development Trends

Smartphones are no longer restricted to elites in the society and they have become very popular with the average mobile user. This explains the huge buzz in the smartphone app development market with hundreds of smartphone developers creating thousands of applications each month. Businesses ranging from top notch MNCs to smaller proprietary businesses are looking at smartphone apps as a potent marketing tool. This increased popularity has led to regular change in the industry trends.
Popular Trends in Smartphone Development
  • High Growth Rate - In the last two years smartphone app market has shown an incredible growth rate. It is estimated that the number of apps developed and download have gone up by three times during this period. The industry is worth more than $7 billion currently and is expected to double up in the next five years.
  • Apple's Sole Show Ends - Smartphone app market was once dominated by Apple but now other competitors have picked up and gaining market share. Most businesses are looking to develop apps for multiple platforms than only for iPhone that was the trend a few years ago. Android development has been heating up in the last two years.
  • Businesses Leading Their Way - Just about two years back only 10% of the top 1000 companies in the world had their presence on smartphone apps. But this figure has grown by leaps and bounds in the last couple of years as many of them have got their smartphone apps developed.
  • Gamer Boys Love It - The increased processing speed and memory in smartphone has aided the mobile gaming market. Many serious gamers now prefer to play games on their handheld devices while on the move.
  • Social Media Buzzing - As like the PC apps, social networking has taken over a large share of the market in smartphones apps too. Millions of users access Facebook, Twitter, MySpace using their smartphones and this number is increasing each year. Many smaller social media companies are turning to their own smartphone apps to make their platform popular.
  • Search Does not Mean Only Google - in the smartphone world search doesn't mean Google alone as many search apps have become popular with the users. Niche apps like those to find a coffee shop or a wine maker are more popular with the smartphone users. In the smartphone world search apps comprise huge market share.
The best way to get smartphone apps developed is to outsource it to offshore development centers in countries like India where you can get your unique smartphone apps developed. Here expert developers will handle your custom development project and provide you with a solid platform to take on your competitors. Outsourcing to India saves you a lot of money thanks to the low cost of hiring skilled labor in the country. Apart from development, you also get awesome post development support from these centers.  by Vishal Arora

The Rise of Smartphones

With every passing day, more and more customers are buying smartphones like never before. This has been fuelled by the increasing number of cheap smartphones that are being introduced in the market by all major smartphone makers.
For the uninitiated, a smartphone is a mobile phone which can connect to the internet and has the ability to run and purchase applications. Even a cheap smartphone is equipped with voice, data, wireless fidelity, Bluetooth and GPRS functions. Operating systems that are most frequently used in cheap smartphones include the Android by Google, iOS by Apple and Mobile 7 by Windows. Most smartphone handsets, including cheap smartphones, use the 3G wireless communication technology and switches over to Wi-Fi whenever it's available. In fact, newer cheap smartphone handsets are being manufactures for accommodating the upcoming 4G technology.
Reports have revealed that worldwide, the sale of mobile phones to end-users totaled over 416 million units during the last quarter of 2011. This was a 35 per cent increase from the corresponding quarter in 2009. The sale of smartphones, including cheap smartphones, grew over 95 per cent from the third quarter during the last year. Smartphones constituted over 19 per cent of the total sales of mobile phones during the last quarter in 2010.
The United States has over 290 million mobile phone subscribers and mobile phone penetration in the country is over 92 per cent. More than one household in every four had mobile phones and no landline connection. Thus is an increase of over 2.1 per cent than 2009. Almost one household, in every six, use mobile phones exclusively despite having a landline connection. Across the world there are nearly five billion smartphone users, a substantial percentage of who use cheap smartphones.
As networks equipped with higher speeds are built, it's expected that an increasing number of customers would switch to mobile internet. Smartphone owners are downloading thousands of applications and spending huge amounts of money via mobile payments. The younger generation, today, use their smartphones for most of their e-commerce transactions. And the most surprising part is that most of them haven't been to a bank in years.
With more number of people taking to smartphones, the concerns about mobile phone security are also bound to rise. If you're one of those who have bought a smartphone, use a unique number code to lock your phone. Over 50 per cent of smartphone users don't use it and their handsets become more vulnerable to thieves and hackers. Besides, don't store any banking password in your smartphone. Nearly 24 per cent users do so and 40 per cent of these people say that losing their handset would be worse than losing their wallet. Over two million cell phones are stolen or lost each year. That's one phone in every 15 seconds.
As more mobile phone manufacturing companies focus their attention on making cheap smartphones, this segment is slated to witness a tremendous growth in the coming days. Add to that the lowering of subscription charges and smartphone users would have a gala time.  by Prabuddha K Neogi

Software Piracy 236

It's Best To Avoid It in the slightest degree prices

Like electronic identity theft, laptop viruses, and the spread of other laptop crimes, software system piracy is on the rise. the matter with software system piracy is that software system prices build this illegal activity appealing to the top user. After all, United Nations agency is it getting to hurt? wealthy software system companies?? this text investigates software system piracy as a full and the impact that it's on the computer exploitation business.

The most vulnerable victims of software system piracy square measure software system businesses or independent programmers United Nations agency create and distribute business software system or shareware. we delineated  shareware in another article, but as a result of both business software system and shareware require payment, they're the target of pirates United Nations agency request to form these sorts of programs liberated to use.

Depending on their binding legal agreements, licensing typically permits the use of a single program on a single laptop. This discovered is sometimes fine for a user United Nations agency uses software system at home on one laptop. but in an atmosphere where there square measure 5, ten, twenty or more computers, shopping for a license for each laptop will be down-right costly. thus costly that the temptation to pirate a bit software system here and there will be pretty tempting.

Co-workers square measure familiar with this temptation and they're usually the ones United Nations agency "share" purchased software system among people who need it. but a similar temptation additionally prompts others to wittingly or unwittingly buy bootleg copies of commercial software system or registered shareware. 

As tempting because it is, it's still criminal and the punishments/fines for sharing business or registered software system is simply too abundant for one in touch. In recent news, "Yahoo China loses music piracy case (AP via Yahoo! News) A court has ordered Yahoo Iraqi National Congress.'s China subsidiary to pay $27,000 for aiding music piracy, the company and a music business group said Tues."1 in addition, "EU lawmakers approve prison terms, fines for major business piracy (International Herald Tribune) EU lawmakers voted Wednesday for legislation that may set prison sentences and fines for large-scale business piracy, but exempt patents and copying applied for private use." 2

Fortunately, there square measure alternatives. faculties can analysis student versions of commercial software system or evoke a school discount. just because school rates are not publicized , it doesn't suggest that they aren't offered. package or open source software system (also delineated  in another one amongst our articles) is another various to pirating commercial-ware, similarly as shareware. And exploitation older versions of programs might in addition reduce the prices related to business versions.

Up until recently, vox populi held very little faith in package or open source software system - usually concerning it as low-quality knock-off's of better best-known business products. but if you take an honest scrutinize what is being offered at no value, you'll be certain  an enormous surprise. the quality of today's package and open source software system created a robust rift among the business community and it's literally driving the competition bananas! so much thus, that even some acknowledge software system development companies have joined the cause and designed a few package open source products of their own!

If you'll keep in mind that there square measure hoards of alternatives to costly business software system (and you make the trouble to induce it), you may discover that you can sustain with the remainder of the computer business at a significantly cheaper value than if you tried to pay your means down the software system aisle. software system piracy simply isn't the answer.

Compression - The Basics

What is Compression?

Basically compression is a process that helps reduce the dynamic range of a track or an element within a track. By using a compressor we help control signal input, so the level of a synth or vocal for example, stays at a constant level. Why would you want an instrument or vocal to have less dynamic range? Well if parts of a vocal or instrument were really loud and other sections were quiet, they wouldn't fit in to your mix, as the quieter parts would disappear behind other instruments and the loudest parts may cause the track to clip. Employing a compressor would capture the loudest parts and pull the volume down, so the difference between the loudest and quietest parts would be reduced. This boosts the average signal level, which allows you, as a result, to increase the volume and make the audio louder.

Our ears determine the overall volume from the average level (RMS) not peak value (top level)!

Compression Settings

To understand more on compression, it is important that you learn the affect each control will have on your sound. These basic settings found on most compressors are:

• Threshold
• Ratio
• Attack
• Release
• Hard Knee/Soft Knee
• Make-Up Gain


The threshold is the level in dB where the compressor starts to function. By lowering the threshold you will begin to hear the peaks reduce in volume, as the compressor squashes them. The amount of compression you are applying, by lowering the threshold, will also be visually apparent on the gain reduction meter.


The ratio is the amount of compression that will be applied after the signal exceeds the threshold. A ratio of 3:1 means that if the signal exceeds the threshold level by 3dB, the output signal only exceeds the threshold by 1dB. So the higher the ratio the more the exceeding signal will be squashed by the compressor.


The attack is how quickly the compressor reacts to a signal that exceeds the threshold. A fast attack will clamp onto the initial transients of a sound, so in a drum bus for example a fast attack may be useful to reduce the harshness of a kick drum and snares attack. A slower attack however, maybe more suitable on the master bus when you aim to keep all the transients in tact and focus on warming the track up.

The release is how fast the compressor will return to its normal state after the signal has moved below the threshold. The faster the release, the more you will begin to notice a 'pumping' effect. If used cautiously this can be highly effective in dance music and is commonly used on a drum bus to allow the percussion to pump around the kick drum.

Hard Knee/Soft Knee

As with a fast attack setting using the hard knee parameter will squash the incoming signal as soon as it exceeds the threshold on the compressor. Using the soft knee parameter however, will apply the compression much more gradually and naturally to producer a smoother outcome.

Make-Up Gain

The make-up gain is the final stage of any compressor. When the signal has been compressed it will, as previously explained, reduce the volume of the threshold-exceeding signal. This will boost the average signal level but in turn will reduce the peak level of the signal. By using the make-up gain you can then increase the signal to its pre-compressed level. by Andrew A Charlton

Understanding Compression 462

What it is and what's involved

Downloading files from the net has invariably been one in every of the most in style activities on the net - third to causing email and browsing the net. we have a tendency to download files from code libraries, ftp directories, YouTube and Google Video, MP3 sites, and that we download files sent to United States as email attachments.

Being thus in style Associate in Nursing activity, it's imperative that you compress the files destined for one more pc. File compression combines variety of different files into one file, and it also can significantly reduce a awfully large file to a smaller one. As a result, the transmission of a compressed file across the net is quicker and sander. this article appearance at compressed files somewhat nearer and it describes how to compress and decompress them victimisation two of the most in style archiving programs.

Identifying Compressed Files

Most files ar compressed in .zip format (if you are victimisation Windows) or .sit format (if you are using a Mac). the 2 hottest code programs accustomed compress and decompress files ar Winzip and StuffIt severally. There ar alternative programs that do an equivalent factor and also there ar even programs that may compress and decompress files for each the Windows and the waterproof system. but since Winzip and StuffIt ar the most in style, we are going to assume you'll use either one to compress and decompress your own files.

If you download a compressed file from an internet site or file library that ends in Associate in Nursing .exe extension, note that although the file is compressed, it's usually a file that will install a program onto a pc. .Zip or .Sit files don't install code - they merely archive a set of them into one, or they significantly reduce the size of a larger one.

Decompressing Files

Assuming that you have Winzip or StuffIt put in on your pc, you'll be able to access the files archived within a .zip or .sit file by merely double-clicking the archive (a file ending in an exceedingly .zip or .sit extension). Double-clicking one in every of these types of files can open up a window that displays the contents of the archive. In most cases, you'll be able to double click a file within this window to use it, otherwise you can select it and drag the file to a folder to look at later.

Depending on how you elected to put in Winzip or StuffIt, you will be ready to right-click a .zip or .sit file and have the program extract its contents into a brand new folder for you.

Compressing Files

When you wish to transfer a file or email a set of files to a follower, it is best to archive it as a .zip or .sit file first. this can decrease the time it takes for your pc to send it elsewhere, and it'll conjointly decrease the time it takes for someone else to download it.

To create your own .zip or .sit file, you'll be able to select one file or a gaggle of files from at intervals mortal, and right-click the choice. Again, betting on how you put in Winzip or StuffIt, you'll be able to click the "Add to Zip" or "Add to Sit" possibility and have these programs mechanically archive the file(s) into one.

Some files compress better than others and in some instances, you will not notice that much of a distinction. The files that compress the best ar pictures, documents, and transmission files. workable files (files that end in Associate in Nursing .exe extension) don't compress that well, but when they're archived with a sizable number of alternative files, they compress rather well. Go figure!

Operating System - Understanding the Operating System

Every new pc that is brought home from the store has associate degree operating system installed onto it. however what most new pc users do not realize, is that while not associate degree operating system, that pc would be a straightforward shell of prospects. A steam-powered pc lacking associate degree operating system would not show something over a bunch of confusing text messages that describe the computer's boot process. At the very finish of this process, the computer looks for associate degree operating system and if not found, it'll prompt the user to inform it wherever it is.
Earlier computers didn't have associate degree operating system and if you have got experience with the computers of the first eighties, you'll keep in mind that most to them didn't even have a tough drive! These old computers shoed associate degree MS-DOS sort operating system from drivers keep onto a disk, and so as to use a program, users would remove the boot floppy and so insert a brand new floppy that contained the program. The floppy not only keep the program (word processor, computer programme, etc.), it also keep the drivers that the program needed to speak with the computer's hardware. As you can imagine, the cumbersome process of switch from floppy to floppy prompted the birth of the operating system.
An operating system is a software system program that controls how the computer's hardware (and installed software) works. It manages the activity of every part and so displays that activity as a user-friendly interface (GUI). It keeps track of wherever things exist on a computer's drive similarly. however perhaps most significantly for the end-user, the operating system is accountable for translating commands issued with a keyboard and mouse into code (010110101 stuff) that may communicate with a group of speakers, a printer, a scanner, and more.
With associate degree operating system installed onto a computer's drive, users now not have to be compelled to boot a pc with a disk, nor do they have to run programs from a disk. All the drivers of a program ar keep onto the computer and used whenever a program is started.
Apple's Macintosh pc was among the primary of a couple systems to establish a user-to-hardware relationship through a user-friendly interface. Today, we've quite a few in operation systems. a number of the more fashionable ones ar Windows visual image, Mac OS X, ZETA, IBM, Unix, and Linux. however even still, in operation systems have extended onto to non-computer devices like game consoles, moveable music players, and PDAs. no matter the device, the operating system installed onto it serves a similar purpose across the board: to change user-to-hardware communication.
When you have faith in upgrading your pc to a brand new operating system, use caution to create certain that you have the necessary hardware elements. we have a tendency to tried to upgrade one in all our Windows 98 machines to Windows XP, however we have a tendency to were cautioned that the former may not be hardware compatible with XP technology. Apparently, the Windows XP operating system requires elements that we have a tendency toren't developed at the time Windows 98 was distributed and if we were to put in Windows XP on this machine anyway, the new operating system would hunt for hardware that the computer didn't have. which would be a rapid recipe for failure.
Also be careful regarding installing in operation systems that ar incompatible with existing hardware. The hardware of Macintosh computers is extremely completely different from the hardware of Windows computers and beneath no circumstances can a Windows operating system work on a Macintosh machine!
