Advantages And Disadvantages Of Shareware Software Programs
Dec 08, 2011 The rule made by the owners of proprietary software was, 'If you share with your neighbor, you are a pirate. If you want any changes, beg us to make them.' ' Free software gives users the freedom to study how the program works by accessing the source code, writing additional code, testing, modifying and distributing it. As with any dieting plan, there are advantages and disadvantages of the Jenny Craig program. The primary advantage is that there is no guesswork in the program.
'Give a man a fish and you feed him for a day. Teach him how to fish and you feed him for a lifetime.' We are living in a world which encourages a culture of proprietary software.
Most of us have always used only proprietary software on our computers. Our children are being taught to use it, too, but they are partially or completely unaware of free software and the benefits it provides.Educating students signifies a major revenue source for some of the proprietary software vendors. In addition, it is a huge opportunity for these vendors to acquaint future adults with their product and keep their dominance forever. They spend huge amounts of money on marketing to acquire the support of educational departments. As an open source enthusiast, I believe proprietary software is incompatible with education because users are just inert consumers and are legally restricted from examining its source code. Education using computers should be free.
It should not be an opportunity for corporations to ensure their software monopoly. I am not forgetting the fact that proprietary software is sometimes powerful and reliable. However, it does not respect the users' freedom.
Software can be said to serve its users only if it respects their freedom. But designers have been known to add malicious features that spy on users, restrict their use, force them to accept upgrades, etc. Moreover, some states in the U.S. Even boast that they cooperate with proprietary software vendors like Microsoft by accepting freebies with or without understanding the harmful effects of using proprietary software in society. No Corporate ObligationsOn the other hand, free software is a gateway for students to explore and learn.
This article is dedicated to those people who are not aware of the benefits of using free software. 1) Available at minimal costFree software does not mean zero cost software. It is true that most current open source projects are available for free of cost, which leads ambiguity around the commonly used term 'free software.'
So the common saying is, 'Think free as in free speech (freedom) and not free as in free beer (zero cost).' Free software lowers the production cost.
Making a system like MS-Windows costs millions of dollars. But if you produce the same kind of system using a free POSIX version, it would probably cost less than a hundred dollars. 2) Provides full freedomOriginally, computer manufacturers aimed only for hardware innovation and didn't consider software as a business asset. This is because most computer users were scientists and technicians who could modify the software themselves, so hardware was distributed with the software pre-installed.
Later, high level programming languages were introduced which were compatible for almost every kind of computer. That meant even less efficient hardware design could be made to work better. This led to a decline in profit margin for hardware manufacturers who led design innovations and considered hardware as their only business assets.
They had to start treating software as an essential part of their hardware sales, enforcing strict copyright policies. This led to the rise of proprietary software.once said: 'The first step in using a computer was to promise not to help your neighbor. A cooperating community was forbidden. The rule made by the owners of proprietary software was, 'If you share with your neighbor, you are a pirate. If you want any changes, beg us to make them.' 'Free software gives users the freedom to study how the program works by accessing the source code, writing additional code, testing, modifying and distributing it.
These things are prohibited for proprietary software. 3) No imposed upgradesFree software never disappears like proprietary.
If proprietary vendors stop supporting a product, users have two options: either use an unsupported version of the software, or go for an (unwanted) upgrade. Imposed upgrading never happens for free software. For example when RedHat decided to stop supporting their RedHat Linux 7, 8, and 9, various other companies came forward to support them. 4) No spying on usersIf users have no control over the software they are using, it can easily spy on their activity.
Disadvantages Of System Software
The company behind proprietary software often installs features that restrict users from sharing it with others. Since anyone who buys proprietary software must sign a licensing agreement before using it, they are agreeing that the vendor has the right to inspect hard drive content without warning.
Advantages And Disadvantages Of Open So…
This violates our privacy because our computers hold our personal information and daily activities. 5) AuditabilityWhen closed-source software manufacturers claim that they made improvements in the program, improved security and restricted backdoors, users are forced to believe it. Since the source code is not provided, there is no evidence for such claims.
6) Provides better securityIt is a commonly known fact that proprietary software threatens users' security. There is a long history of security vulnerabilities. Proprietary software doesn't necessarily stop the spreading of viruses and letting hackers to take over people's computers for sending spam. Because the software is secret, all users are dependent on the corporation to fix these kinds of problems. 7) No monopoliesIt is easier and cheaper to switch from one free software to another compared to switching proprietary software. Free software does not tie you down to any corporation.
8) Truly user-orientedOne of proprietary software's major claims is that free software is not user-oriented. A proprietary vendor used to listen to its customers' needs and respond and develop accordingly. But companies like Red Hat and IBM are crafting strategies that rely on all end users having the same needs. 9) No lock-in standardsProprietary vendors lock-in proprietary standards to ensure that their users will become returning customers. Free software works in open standards.
10) Part of social movementFree software is not just for the individual user's sake. It promotes social solidarity and represents society as a whole through sharing and cooperation. Since our activities are progressively digitized, free software is becoming an even more essential part of our culture and life activities.Let's put our hands together and take a pledge for a better world by using free software. Spread the idea of freedom. A funny quote comes to mind: 'Software is like sex, it is better when it is free.'
How does it work?From a business user perspective, open source software works in much the same way as provided by commercial software firms – the only difference being that generally you don’t pay for it. However there are a few important differences – the idea behind open source software is that users are effectively co-developers, suggesting ways to improve it and helping to hunt out bugs and problems.This means that if you wish, you can modify it to your own needs, port it to new operating systems and share it with others. What are the advantages of open source software?. It’s free – it has been estimated that open source software collectively saves businesses $60 billion a year.

PANASONIC AG-450 S-VHS Reporter Camcorder with Case & All Accessories (RARE!) - $332.21. Panasonic S-VHS Reporter Camcorder with Case and all the original Accessories (Model# AG-450). Very RARE vintage S-VHS camcorder. Very GOOD condition, fully functional. Previously used for broadcast television news. I believe it's from the early 90's.
Product Information. Before smartphones and digital cameras, VHS cameras like the Panasonic AG-450 Camcorder captured special occasions such as Christmas, birthdays, and baby's first steps.
This camcorder is hand held but large in size, making it best suited for a tripod. Its wide lens has an optical zoom of 10x gets you up and close to the action and renders very crisp and clear images. A boom mic over the lens insures quality sound transmission. Video recording away from a power source is accomplished through its 2V 2.3Ah SLA battery, which is recharged when the camcorder is plugged into its AC adaptor. Playback is viewed either through the camera itself or on a TV when connected via audio/visual input/output ports.
Paying Its WayAG-456UP S-VHS CamcorderPanasonic Broadcast & Television SystemsOne Panasonic WaySecaucus, NJ 07094($2495)The Panasonic AG-400 series of S-VHS camcorders has set a standard for providing high-quality, industrial-level camcorders at consumer-level prices. Notable features in past models have included a two-CCD imager section (AG-460) and vertical interval time code support (AG-455).The newest entry into the series is the AG-456UP, a direct descendent of the AG-455. While the AG-456UP has only a single image chip, it does offer VITC time code, as well as enough features and controls to stand tall in the semi-pro camcorder market.The unit retains the shape of past AG-400 series camcorders and is about the same size and weight. Those unfamiliar with this line will find the AG-456UP light for its size and very comfortable to use. Designed for right-shoulder shooting, all camera controls sit in a logical arrangement on the left side of the body near the lens. Most of the controls are push-button types. There is minimal tactile feedback from these buttons–it’s good that the viewfinder indicates when a feature is engaged.
Only What You NeedThe AG-456UP has 12:1 zoom lens with 100x digital zoom. If you need to get video of an extremely smallsubject, the macro function will focus as close as 1.5mm away from the lens. Panasonic says the zoomrocker switch is continuously variable right up to where the digital zoom mode kicks in.
I was able todistinguish just four distinct speeds in each direction. Even with just four zoom speeds, this is animprovement over the AG-455’s zoom.The most significant improvement in the AG-456UP’s lens assembly is the addition of a manual zoom lever. This lever, which was missing on the AG-455, makes it possible to perform quick focal lengthchanges. No serious camcorder should be without this control.Focus, iris and white balance controls are automatic with manual overrides.
The manual iris override is an absolute control, meaning it will not shift once you’ve established an iris setting. This is preferable to those “manual” iris controls where auto iris continues to function after a level is set. The viewfinder indicates the present f-stop and white balance setting in both auto or manual modes. A low light button acts as a backlight button, opening the iris for backlit or low light situations.When in the manual mode, you have a choice of eight shutter speeds controlled by the + or – buttons. The range is from normal (1/60th of a second) up to 1/8000th of a second. Panasonic points out that using high shutter speeds in fluorescent lighting will subject the image to flickering.You view your scenes on the monochrome 0.7-inch viewfinder. An on-screen display (OSD) button enables in-viewfinder indicators.
The viewfinder has indicators for white balance, tracer, digital wipe and mix, gain, low light and self timer/interval recording. A sliding diopter adjustment sets the viewfinder focus for your eyesight. The AG-456UP gives you several digital effects including Still, Strobe and Tracer. The still function freezes images, filing them in memory for later use. You can wipe or mix (dissolve) from your current image to any image captured with the still effect, and visa versa. The AG-456UP allows only one still in memory at a time.
Strobe offers the familiar stop-motion effect common on many camcorders. The tracer effect produces a ghost-like after-effect to moving images. A fade button fades your images in or out to.The interval recording control allows you to record one second of video every fifty seconds for time-lapse effects. You can set a timer to automatically stop recording after twenty seconds.Audio comes into the AG-456UP through the attached stereo mike. A switch on the side of the mike allows for selecting wide, tele or zoom modes. A mike jack allows use of an external stereo mike.Built into the left side of the unit is a small loudspeaker for monitoring audio while recording.
It also provides audio during playback. There is no headphone minijack. Instead, Panasonic suggests using anRCA-to-minijack stereo adapter to connect headphones to the AG-456UP’s RCA-style audio outputjacks.A sliding plate on the top of the AG-456UP switches the unit between record and playback modes, revealing the VCR transport controls. All external connections are on the rear of the unit. Included are stereo audio, composite video and S-video connectors.

A switch selects between hi-fi, normal (mono) audio, or a mix of both for playback. Another switch disables the built-in monitor speaker.A DC power connector allows for external power from the battery charger or a car cigarette lighter.A 5-pin Control-M connector allow you to hook the AG-456UP up to any edit controller that supports this protocol.
The unit’s internal VITC generator/reader will send VITC information out to the editor through this connection. The AG-456UP will generate up to 24 hours of uninterrupted time code provided you do not record over a pre-recorded section of tape, or remove the tape from the unit (which re-sets the time code generator).If you prefer to edit in the camcorder, the unit’s flying erase heads allow fairly accurate insert editing.
You can also audio dub to the normal audio track. You’ll find instructions for both procedures in the well-written manual.The AG-456UP does not include a remote control.Shootin’Except for those improvements mentioned, the AG-456UP is nearly identical to the earlier AG-455.It’s made for serious shooting and it produces serious results. Recorded images are quite sharp with goodcolor, once you get used to the white balance settings.
There is a tendency for images to go red if you don’tproperly white balance in the manual setting. When set properly, colors are quite accurate.Big as this camcorder is, it was not uncomfortable to use for long periods. A shoulder cushion (actually hard rubber) built into the bottom of the unit works nicely.Audio is superb compared to other standard VHS hi-fi units. However, the small speaker doesn’tprovide the audio quality of headphones. Panasonic could have eliminated the hassle of using an adaptercable by simply adding a headphone jack.The manual zoom lever, missing on the AG-455, is sure nice to have for quick zooms and manualfocusing. This lever has since disappeared on many smaller consumer camcorders.
I don’t understandwhy.The AG-456UP is probably overkill if you just want to chronicle the growth of your kids or the antics of the dog at a family picnic.
