Online Virus Scanner

Online virus scanner is a web based application, basically using the same engine as a mainstream antivirus product. To remove found infected files or not is the  choice of antivirus manufacturer.Of course, A User needs not only to know of having infected files, but and remove them.
Nowadays there are about 20 mainstream Microsoft sertified Online Virus Scanners.

More honest antivirus manufacturers include infection removal function into their scanners. More greedy - suggest paid assistance for it. Basically Online Virus Scanner requires Javascript enabled and Internet Explorer 6 or higher as a browser. Some Online Virus Scanners (such as Escan Antivirus Toolkit and Windows Safety Scanner) check and repair registry errors too.

Some Online Virus Scanners ( for example, Dr.Web CureIt, Emisoft Emergency Toolkit, or, again, Escan Antivirus Toolkit) are not really "online" - they are uploading into computer, but not require installation). What scanner to choose? Checking all of, i would recommend the following ones:

Escan Antivirus Toolkit (product of India!) - scan for viruses, troians , worms. Immediate infection removal. Regisry repair.  Microsoft sertified.

Emisoft Emergency Kit (former A-Squarred) - scan for viruses, troians , worms.Removal on demand. Dual (Ikarus+) infection search engine.

Dr.Web CureIt - Russian top 2 Antivirus (along with Kaspersky).Good deep check and repair.Hosts file repair, boot repair. Microsoft sertified.

Eset Online Scanner - good deep scan and repair.  Not the most quick. Must have.

VIPRE Rescue Program - a command-line utility that will scan and clean an infected computer that is so infected that programs cannot be easily run. Microsoft sertified.

F-Secure online scanner - Runs with installed antivirus. Good tool.

McAfee Labs Stinger - rootkit retriever.

Kaspersky online scanner is now under renewal, but you can use Kaspersky Virus Removal Tool. Why-not-to-have tool.

ArcaVir Online Scanner - CanHelp tool. Microsoft sertified.

Here it is. All of those are Microsoft sertified, free for check and repair. I would say, click-check-repair-forget-tool. So, if your PC is "stupid", or if you notice some suspiсious file activity - check your computer for viruses, worms, troians, adware and spyware! If you are not a user with a PC security paranoia with 5 antivirus system installed, i would reccomend you to check your computer. And remember - order, size and volume mean!

Benefits of Bluetooth Mouse

Bluetooth mouse uses wireless technology with laptop and personal computers having integrated Bluetooth receiver. It is a good alternative to the touch pad and is a one piece, ultra-portable device. The Bluetooth mouse uses Bluetooth 1.2 wireless technologies with adaptive frequency to reduce interference from other wireless devices such as Wi-Fi laptops or cordless telephones. The Bluetooth mouse has a battery life up to three months.

Bluetooth mouse has an optical engine, which gives a smooth, precision tracking on a wide range of surfaces, and it is most useful for a mobile professional using the mouse while traveling. Bluetooth mouse is based on powerful laser technology that has 20 times the performance of standard optical tracking giving more accuracy and responsiveness.

The main difference between a regular wireless mouse and a Bluetooth mouse is the Bluetooth connectivity which is most suitable for laptops, getting rid of cords. It is relatively thin and technologically and physically does not look like a standard mouse.

It is enough to attach the USB cable to the computer and there is no need for any batteries. Bluetooth mouse buttons are conveniently positioned near the right thumb for right-handed users and has a 10-meter free space range. This cordless Bluetooth mouse is comfortable and has an ergonomic curve which fits naturally into most sized hands. Bluetooth mouse goes into power saving sleep mode automatically during periods of inactivity and a simple click awakens it.

In fact Bluetooth mouse is best suited for mobile professionals who despise carrying full sized, bulky mouse with a mesh of cords and the added advantage of Bluetooth mouse is that it gets recharged inside the laptop itself and offers absolute freedom from wires.

Bluetooth mouse is easy to setup and requires no separate desktop receiver. The USB adapter included in the mouse allows connection of up to seven other Bluetooth devices.
Setting up a Bluetooth mouse is very simple. After going through the initial process, the mouse can be connected by turning it on through a switch at the bottom and by tapping any button, it starts working. There is a red glow from under the mouse and the angle at which the mouse is seated is arranged to be optimum

The precision of the mouse is made near perfect due to the needle thin tip of the semi-transparent pointer. Using a keyboard and a Bluetooth mouse together provides a great relief to persons who want to avoid carrying wired devices with them. Bluetooth mouse helps a great deal in mobile computing.
.
Generally, Bluetooth mouse has three buttons, the standard right and left buttons, and a third one where the thumb rests. The third one is preset as a back button to use the default web browser and is designed in such a way that it is for right handed people only. The scroll wheels' cover ensures that the fingers don’t slip while scrolling.

Increasingly Popularity of Webcam

Instead of just communicating over the internet with text and emoticons, people are beginning to realize just how easy and fun it is to send video clips through cyberspace. Webcam setups range from simple to complex, and increasing the complexity is only a matter of adding functionality through software, custom code and/or equipment connections.

A simple Webcam setup consists of a Digital Camera attached to your computer, usually through the USB port. The camera part of the Webcam setup is just a digital camera -- nothing out of the ordinary so far. The "Webcam" nature of the camera derives from the software. Webcam software takes a frame from the digital camera at a preset interval (for example, the software might grab a still image from the camera once every 30 seconds) and transfers it to another location for viewing.

If you're interested in using your Webcam for streaming video, you'll want a Webcam system with a high frame rate. The frame rate indicates the number of pictures the software can grab and transfer in one second. For streaming video, you need a minimum rate of at least 15 frames per second (fps), and 30 fps is optimal. To achieve high frame rates, you must necessarily have a high-speed internet connection.

Once it captures a frame, the software broadcasts the image over your Internet connection. There are several broadcast methods. Using the most common method, the software turns that image into a JPEG (compressed) file and uploads it to a web server using File Transfer Protocol (FTP). You can easily place a JPEG image onto any web page in this manner and post your webcam images on the internet.

If you don't have your own Web server or web site, you can also use your web cam to send a video email. First, launch the software that comes with the camera. Depending on the model, the process of e-mailing and recording your video messages may vary. Press Start or Record to begin the video message. Click Stop and then preview the video. You can then click E-mail or Send, which automatically opens your default e-mail program.

When sending a video e-mail, the longer the video message recorded, the bigger the attachment will be, so make sure the recipient's computer can handle the size. The recipient of the e-mail does not need special software to see your video message; they simply choose to open the attachment and the mini movie will play.

Another increasingly popular way to use your web cam is a chat session with webcams in "real time" with instant messaging (IM) programs. During an IM chat, there will be an option to start the webcam right on the screen, or under the Options or Tools menu. In Windows Messenger, for example, the words Start Camera are on the right-hand side of the screen. It is also possible to adjust the volume, window size, and video resolution with IM options. The person on the other end also needs a webcam to visually chat.

Adjust your camera's focus, point it toward your face, and most importantly, look right into the "eye" of the webcam so your friends on the other end see more than just your forehead. Keep in mind that some webcams require an additional microphone to record audio.

Don't expect terrific video quality. It's often possible to adjust the video resolution by toying with the webcam's software settings, but the higher the quality, the choppier the video frame rates will be. Webcams can also be used for remote security monitoring, but beware of hackers who could intercept your video feed and then spy on YOU. Make full use of passwords and encryption

Online Education for Disabled Students

Online Education for Disabled Students Almost all online universities offer education programs for disabled students, as mandated by the ADA (Americans with Disabilities Act). To avail full benefits of online education, it is quite vital for disabled students to prepare themselves really well. To start with, disabled students should make themselves mentally strong, as this would help them deal with all sorts of situations. Disabled students should work hard in developing self knowledge while studying in online colleges or universities. It’s the responsibility of these students to come up with a learning style that is tailor made for them. To attain success in online education, disabled students should possess learning strategies that are going to work for them. It includes, studying for one or two hour more once the class is over, interacting with faculty members every day and reading textbooks two or three times rather than just once.

Legal Rights

Disabled students should be aware of their legal rights. According to Individuals with Disabilities Act (IDEA), online universities will not have any access to disability records. Section 504 of the Rehabilitation Act clearly states that online universities cannot discriminate against disabled students when it comes to admission or anything related to study.

As a matter of fact, it’s the responsibility of online universities to make sure that disabled students finish their education without any problem. To attain this objective, online schools and institutions are given the freedom to modify their rules and regulations. For example, online universities can allot extra time for disabled students when it comes to tests, projects or term paper. To make the most of these benefits, disabled students just need to submit an application form to their eLearning institution.

Grants and Scholarships

If the financial condition of disabled students is not up to the mark, it’s the responsibility of online universities to provide them with grants and scholarships. Disabled students also attain quite a bit of discount in tuition fee and project report fee from the online universities.

Benefits of Online Education for Disabled Students 

• Disabled students can attend classes from the comfort of their homes.
• Disabled students can attend classes whenever they want. When it comes to online education, what time you attend classes doesn’t really matter as classes are conducted through Internet.
• Disabled students can contact their online faculty even after the class is over. This is quite beneficial for disabled students as they understand things pretty late as compared to other students.
• There are lots of options available for disabled students when it comes to financial aid in online education.
• Most of the online universities provide placement services to disabled students. As soon as disabled students earn their online degree, they will get the job.
• When disabled students opt for online education, they do not need to worry about the study material as it’s the responsibility of online universities to provide them with study material which is prepared by renowned and skilled experts. In some cases, online universities also provide text books and reference books to disabled students.

Differences between BSD and Linux

What is a BSD Unix?

BSD family of Unix systems is based upon the source code of real Unix developed in Bell Labs, which was later purchased by the University of California - "Berkeley Software Distribution". The contemporary BSD systems stand on the source code that was released in the beginning of 1990's (Net/2 Lite and 386/BSD release).

BSD is behind the philosophy of TCP/IP networking and the Internet thereof; it is a developed Unix system with advanced features. Except for proprietary BSD/OS, the development of which was discontinued, there are currently four BSD systems available: FreeBSD, NetBSD, OpenBSD and Mac OS X, which is derived from FreeBSD. There are also various forks of these, like PC-BSD - a FreeBSD clone, or MirOS, an OpenBSD clone. The intention of such forks is to include various characteristics missing in the above BSD systems, on which these (forks), no matter how well they are designed, only strongly depend. PC-BSD, for example, has more graphical features than FreeBSD, but there are no substantial differences between these two. PC-BSD cannot breathe without FreeBSD; FreeBSD or OpenBSD are independent of one another.

What is Linux?

Albeit users like to use the term "Linux" for any Linux distro including its packages (Red Hat Linux, Mandrake Linux, etc.), for IT professionals Linux is only the kernel. Linux started in 1991, when its author, Linus Torvals, began his work on a free replacement of Minix. Developers of quite a few Linux system utilities used the source code from BSD, as both these systems started parallelly in about the same time (1992-1993) as Open Source.

Today, there are a few, if not many developers of their own kernels/operating systems (FreeDOS, Agnix, ReactOS, Inferno, etc.), but these guys simply missed the right train in the right hour. They did not lose anything except for the fact that they may be even better programmers, but without the public opinion acknowledging this at large. Linus built his fame also from work of many developers and he went on board in the right time. Linus deserves a credit as a software idea policy maker and he helped very much in this respect.

(Open)BSD vs Linux

It is often difficult to say what is better if you compare two things without regarding the purpose of their use. Mobile Internet may appear better for someone who travels often, but for people working at home such mobility is not necessary. In this view, it is a stupid question when someone asks: "What is better, a mobile or static Internet?" It all depends...

If you compare Linux and OpenBSD in their desktop environment features, Linux offers more applications than OpenBSD; but in a server solution BSD systems are known to be robust, more stable and secure, and without so many patches distributors release soon after their new version of Linux slithered to light.

BSD systems are based upon real Unix source code contrary to Linux, which was developed from scratch (kernel).

Differences between BSD and Linux

1) BSD license allows users/companies to modify a program's source code and not to release changes to the public. In other words, BSD licenses allow commercial use and incorporation of a code into proprietary commercial products. This is how Microsoft incorporated BSD networking into their products and how Mac OS X earns money through muscles of FreeBSD.

Linux uses GPL license for most of the time (applications in Linux can also have a BSD license - or any license; it is up to developers how they decide). With a GPL-licensed program anybody can change the source code, but he or she MUST share it with the Open Source community to make sure that everybody will benefit from such a change.

2) BSD has the so-called "core system" (without packages). The core system consists of basic utilities (like ssh, fdisk, various commands like chmod or sysctl, manual pages, etc.) and anything beyond this is strictly seen as an add-on. Linux (not only the kernel, of course) is usually packaged as the whole system where this difference is not seen.

3) On BSD systems, all add-on packages are strictly installed into the /usr/local directory: documents to user/local/share/docs/application_name; themes and other things to /usr/local/share/application_name; binaries to /usr/local/bin/application_name. By application_name we mean a program's name, so if you install IceWM, for example, its binary will be here: /usr/local/bin/icewm. With Linux, on the other hand, all applications get mostly installed into the /usr/bin directory.

4) BSD systems use the system of "ports", which are fingerprints of applications in the /usr/ports directory, where a user may "cd" and execute a make command, which will download, via a directive contained in such a fingerprint's code, the application's source and the system will compile it as well. "Ports" are actually add-on packages for BSD systems and they are also packaged in packages repository of a concrete BSD system. They can be installed as binaries, too, with use of the "pkg_add" either directly from the Internet or locally. But "ports" have that advantage that if an author of any package makes a new version, a user can immediately get its newest/updated version. Packages released for a particular BSD version (like OpenBSD 4.1) are not updated and users have to wait for a new BSD release (like OpenBSD 4.2).

5) BSD systems have also their stable version. With FreeBSD, for example, you have a FreeBSD-Release (a version that can be used normally), FreeBSD-Stable (system more profoundly audited for bugs and security holes), and a development version - Current, which is not stable and not recommended for a regular use. Some Linux distributions started to imitate this philosophy, but with BSD systems this way of making distributions has become a rule.

6) Of course, the kernel is absolutely different.

7) BSD has FFS file system; it is the only file system on BSD's contrary to Linux, where you can use dozens of file systems like ext2, ext3, ReiserFS, XFS, etc.

8) BSD systems divide their partitions internally. This means that after installing a BSD system to a hard disk, programs like fdisk, Partition Magic, Norton Ghost and many others will not see this internal division of a BSD (FFS) disk; thus, repartitioning of a disk is not such a pain when administrators require a rigorous partitioning (for /home, /tmp, /var, /etc directories). As a consequence, the naming convention also differs a little: a disk - /dev/ad0s3b in FreeBSD indicates that you deal with "slice" 3 ("s3"), which is the equivalent of Linux /dev/hda3; the internal "partition" has the name of a letter: "a", "b", "e", etc. ("b" is a swap partition). BSD systems also use different naming conventions for devices (disks, etc.)
9) Unless you make a good kernel hack, BSD systems can only be installed into the primary partition. This is not the rule with Linux. However, as BSD systems offer the above-mentioned internal division of partitions, this is not any pain. PC architecture for disks (IDE) follows the rule that you can have only four primary partitions. We will illustrate this on Linux: /dev/hda1 (note: first partition on master disk on first IDE channel), /dev/hda2 (second partition), /dev/hda3 (third partition), /dev/hda4 (fourth partition). PC architecture allows creation of the so-called logical disk on a physical disk (/dev/hda5, /dev/hda6, etc.). You can have as many logical disks/partitions as you wish and you can also install Linux into these "logical disks". On the other hand, installing a BSD OS into such a "logical partition" is not normally possible.

10) System configuration is manual for most of the time, but various clones like PC-BSD break this convention. The manual approach is a very good thing, as administrators have everything under control without being pushed to waste time in a labyrinth of bloated configuration menus. A good comparison is to imagine a car mechanic repairing the car's engine covered by a thick blanket. To give you even a little better example - you will hardly find a Linux distro that does not have a default X startup (graphical environment). Of course, you can switch off the X environment during the installation configuration, but if you keep forgetting like me and forget to switch this off, or you have difficulties to find it in the menu somewhere, you realize that most Linux distributors do indeed impose on us only one approach - to put our fingers first on the thick blanket, then on the engine. If you are a good administrator, you do not usually trust vendors who program you how to use Linux - you are the boss and you must have your own freedom. However, in most cases you lose few hours instead by deactivating various services, which are, unfortunately, not even necessary but almost always activated by default. Linux is praised both for being a good desktop and server, but administrators of a good server do not need X. The more software is stored on your hard disk, the more security problems you will face, because it is impossible to audit every package in every unthinkable situation. Good and secure systems are always tight, light and simple.

11) All BSD systems have a Linux emulation support. Running BSD binaries on Linux is a little harder.

12) BSD systems have less support from driver vendors, thus they lag behind in this view (they are not worse, but many vendors support only Microsoft and Linux). With a BSD system you must carefully research the Internet for supported products/chipsets before purchasing any hardware.

13) BSD systems do not use the Unix System V "runlevel scripts" (initialization startup scripts) like Linux.

14) BSD kernels can be set to several security levels. This is also possible with Linux, but BSD's have taken a very good care of this kernel-tuning feature, which makes it even impossible to change something in files in higher security levels - you cannot delete them.

15) BSD's have everything under one ROOF. Various Linux programs are often not even compatible with other Linuces. For example, if you install a SuSE RPM package on Mandrake, it may not work. BSD's have one solid crown of power. If you move from Linux to FreeBSD, you will soon find out that you got out of this chaos. Do you want a package? Just visit: http://www.freebsd.org/ports/ and download it. Unless its developer made some programming errors, it will always work.

16) Generally, BSD systems boot and reboot faster than Linux. Linux can do this, too, but it must be tuned. It is very surprising that Linux is shipped, on the one hand, on huge DVD's and, on the other hand, it has a compressed kernel. BSD systems do not use (but they can) a default kernel that is compressed, thus the system boots always faster. As I mentioned earlier in this article, Linux vendors program users to use various, often unnecessary services. I do not need SAMBA (file and print services) and many other things as well. Linux reboot process takes longer because various services running on Linux need time for deactivation. Many Linux users do not even know what is the purpose of these services.

17) In comparison to BSD, most Linux distributions are overbloated. Few good users noticed this some time ago and a new trend in the Linux world started with ideas to get closer to a BSD-style use. One of such distributions is Gentoo Linux, but also Slackware Linux, which has preserved a very good shape since its first release (1993). The Gentoo "About" page (http://www.gentoo.org) says that, "Gentoo is a free operating system based on either Linux or FreeBSD..." Therefore, if you use Slackware or Gentoo, these Linuces will always reboot faster than any other Linux.

18) If you compile programs from ports, you will not stumble into compilation errors. BSD packagers prepare their packages carefully, so that users will always compile them successfully. This does not always happen with Linux.

Conclusion

I am the author of One Floppy CD Audio and MP3 Player, and a single floppy OpenBSD router. I really like all BSD systems. If you are interested, look into FreeBSD documentation, which is one of the best. It will give you a very good overview of history and hard work done in the development of these robust systems. Today, BSD Unices are the only quality alternative to Linux in the Open Source world.

Upgradation of Operating System to Android 2.3 tablets

If you would like to upgrade your HTC Desire's operating system to Android 2.3 tablets,  I am going to solve your problem. Because you will find out how it's accomplished. However, this activity is not a quite legal since the official upgrade hasn't been released yet. Click below for more info;



Just get ready to be amazed by  the new customized  Android 2.3 ROM on your HTC device.

First, you have to remember that your phone must be rooted before continuing  and you need to back up all of your data on your device since this rooting activity will wipe all of your data. After the phone has been rooted, download the GingerNinja v0.11 ROM to your computer (extracting the downloaded zip fie is not required).

Once the file has been downloaded to your computer, copy it to your phone's microSD by connecting it to the computer, copy and paste it to the memory card.
After the copy and pasting, the second step is to restart your phone by pressing and holding both the Power Button and the Volume Down button until the bootloader screen come up then boot it to Recovery mode. To boot into Recovery mode, use the volume buttons of your phone to scroll to 'Fastboot' and then select 'Recovery' from the next menu.

The next step to installation is to applythe .zip from the SD card and select the.zip file that you copied to the root of your phone. You have to wait for a moment since finishing the installation needs some time. Once the process is finished, reboot the phone and you will see your HTC Desire runs Android 2.3 Gingerbread.
As long as the device supports the ROM, this method will work for flashing any ROM to any Android device.  However, this upgrade is not a quite legal since the official upgrade hasn't been released yet. Please click on the link below for more information.

Win Free Laptop

Laptops are quite popular these days. Unfortunately, not everyone can afford one. If you are one of those people who really need one and can't buy it, then this article is for you. It will explain to you how to get one - for free! Nearly everybody can get a free laptop online.

There are plenty of free laptop contests on the Internet. On the first glance they look suspicious, too good to be true but some of them are legitimate. If you participate in them you could win free laptop quickly.

You just need to stumble on the right contest, and to qualify for the prize. To qualify you are required to follow the program's guidelines. You can definitely win free laptop fast and easy if you follow the guidelines and if you are persistent.

This is Why Some of These Contest Exist

This may appear shady but there is a reason why there are contests like these. Big computer manufacturers on occasion pay big money to advertisers for free laptop giveaway contests. This builds up the brand of the company big time. It also benefits the customers. Sometimes, the giveaways turn into the win free laptop contest that you see online.

How to Participate in the Win Free Laptop Contests 

Generally to participate in the contests you would need to fill out a simple form, requesting your email address. You need to make sure that you enter a legitimate e-mail address so that you can participate. You should not worry about giving away this kind of information, if the site seems legit. If you are paranoid about your information you could use separate email for the contests. This way your personal e-mail address will not jumble with the participation messages you will receive from the contests.
Typically, when you see these type of contests you shouldn't be indecisive. It might be a good idea to roll in. You will loose nothing and you could win free latop!

If you have already tried searching online for win free laptop you may have faced the same problem as me, there aren't a lot of web sites that offer the laptops for free. Many of them are on paid contracts and it is not hundred percent free like they say. However, there are some legitimate limited time contest. You just need to find the right contest and jump in http://www.winfreelaptop.info/

Track Anyone Anywhere by Mobile Phone

Mobile phone tracking is a system that works to track the current position of a cell phone no matter where the owner is located. This technology allows a phone's location to be uploaded to a website where friends and family members get to view the person's last reported position. The tracking of anyone, anywhere through his or her mobile phone is made even easier and practical with free mobile phone tracking systems.

In order to locate or track a phone by using this tracking system, it must emit a roaming signal that can be detected by a nearby tower which has a communication antenna. GSM localization which uses multi-lateration that is based on the strength of the phone signal will then determine the location of the cell phone to locate the user. Location based services that use mobile positioning will disclose the exact coordinates of the user.

An advanced free mobile phone tracking system allows for a more accurate location in which the mobile phone is present and is able to produce an estimate distance to the base station. 

Approximation by interpolating signals that travel between the two antenna towers will then give a much accurate location. In urban areas, mobile phone tracking services can reach close to 50 meters as the mobile traffic and density of antenna towers are very high. However, mobile phones that are located in rural regions that are far from base stations will not be precisely located through the service

The use of latest mobile phones is more easily located by mobile phone tracking systems as they contain inbuilt phone tracker system which emits signals even when they are not in active calls. Estimation of the location of the mobile phone and its user is easy through comparison of relative signals and their strength from various antenna towers. With the help of roaming procedures, the location is estimated in a matter of seconds.

With the latest technology in the mobile phone trackingfront, you are now able to use it to ensure the security of your loved ones or for finding stolen or lost mobile phones.

Vector and Raster Images

What is a raster image?
A raster image is made out of a certain number of pixels. It can also be called a bitmap or a digital image. A raster image can be saved in files with different extensions, such as JPG, BMP or GIF. Pixel is the smallest unit of your computer screen that you can actually control. Pixels form areas of colors which create the finished image. A certain color is assigned to each pixel. Raster graphics use RGB (red, green and blue) color system which reveals a wide range of colors in the image.

What is a vector image?
A vector image is the collection of different elements and objects. Vector image is not that common as raster image. All the objects are scalable and consist of points connected with lines and curves. The objects and elements can be expressed by mathematical equations. That is the reason why vector graphic does not depend on resolution. It can easily be resized without image quality loss.
Note: Sometimes, when you resize a vector object, make it smaller or lager, some defects may appear in a final image.
You may also edit the attributes of the vector objects and elements such as outline, fill and color. Editing will not affect the basic object. The vector file size is usually smaller than bitmap image. It doesn’t contain the image itself, but only the elements defined by mathematical equation.
One thing the vector is not suitable for is making realistically looking images. Vector graphics will look cartoonish.

What are the vector graphics formats? 
The most commonly used vector formats are EPS (Encapsulated PostScript), PDF (Portable Document Format), AI (Adobe Illustrator), SVG (Scalable Vector Graphics).

How to convert from raster art to vector art? 
The most powerful tool to convert raster image to vector isVector Magic. This program allows you to convert any JPG, BMP or GIF images to the most popular vector formats.
It really can do amazing things. All kinds of images can be converted. It processes not only simple logos and labels, but also complex and rich graphics. It may be photos with thousands of colors, detailed and neat images. If you compare the result you will not see the difference between raster image and vector image. Output vector image is 100% accurate. This application is perfect for conversion in vector format. You will have a chance to improve the resulting image. The level of detail can be high, medium or low. There is an option to customize particular colors or choose unlimited color palette. With advanced features you can remove the background and edit the results. The easiest way is to choose fully automatic mode with single-click vectorization.
The results will not disappoint you. This program is extremely easy to use even for the novice.

Review result

Note: you cannot save the results in trial version. However, you can register on the program’s homepage. There you will get two tokens for free online conversion.

What are vector images used for? 
Vector graphics are perfect for the images that require scaling, stretching or shrinking. It may be anything from simple company logos to huge billboards. Pages layouts, maps and illustrations usually have vector formats. Printing companies require vector graphic files.

What to use for work with vector art? 
The most popular programs for creating and processing vector graphics are Adobe Illustrator and Corel Draw. They are shareware programs and have been the  leading products on the market for a long time. They approved themselves in this field.
Inkscape is an application for processing and managing vector graphics. It is open source software, and you can use it for free. It is capable of performing the same work as Adobe Illustrator and Corel Draw. Inkscape has support for SVG format. Inkscape provides many features such as markers, clones, shapes, paths, alpha blending, gradients, and patterns. You can trace bitmaps and edit nodes. The program is multifunctional in terms of enhancing vector images. The interface is very smooth and simple to use.

Inkscape

Note: there is an option to trace bitmaps. It means you can vectorize the raster image. The quality of the output vector image is not as good as of the Vector Magic application’s one. However, traced graphics can be saved and modified.

Chrome, Firefox, and Opera for Android

As you may have noticed, we're quite keen on comparing web browsers and their peculiarities, looking for promising innovations in them. This article follows suit, and we're going to try and help you decide which mobile browser to choose. I'm not going to speak about which one is faster or uses less resources, I want to focus on usability and comfort for the ordinary user.

When we speak of desktop versions of Chrome, Firefox and Opera, we agree that despite their apparent similarity they all have some unique features. So the choice of your primary web browser usually comes down to the question of habit and comfort. I consider it to be true for the mobile versions of those browsers as well. So let's see if those are any different from one another.

Visual Side

Comparing Chrome, Firefox, and Opera for Android, there is no way we could neglect the most obvious part of these apps – their interfaces. If you look at the first two you will find them very similar: same design language, same elements (unified address/search box and tabs button). All other options are available via your phone menu button. Opera Mini stands out from the three with an interface furnished with several additional navigation ribbons: one at the top and one at the bottom. The upper bar is split into two boxes: address bar and search box. The bottom bar has navigation buttons, a tabs button, and a button to access the main menu (your phone menu button may not work here).

This is What You See First, Opening the Browsers

Tabs

Tabs are where these mobile browsers differ the most. I found their realization in Chrome to be most comfortable and novel: tabs are organized like a deck of cards, they can be piled up, and easily deleted (in a natural gesture of making a diagonal line). Another novelty is that you can add a lot of empty tabs without having to enter any target websites the very moment you create those tabs.

Firefox for Android organizes tabs in a long list, which you can scroll (the page you're currently viewing is lowered); it also asks you to indicate which site you intend to visit the very moment you create a new tab, you can't have empty tabs at all. Opera Mini does the same, but it keeps your tabs organized in a pop-up ribbon with thumbnails of the respective pages. Also, while you're looking through them, you can still see the page you're on.

Opera Mini, Chrome and Firefox Tabs' Orginization

Want to Synchronize?

There is not much to say about synchronizing these mobile browsers with their desktop counterparts. All three can do this automatically.

System Support

This is where a lot of differences can be found. Chrome is created for owners of smartphones and tablets that operate under Android 4.0 and above; so if you have an older device, you won't be able to use it. Firefox is better in this respect, it works just fine on Android 2.2 and up. Opera beats the two supporting not only Android (1.5 and up), but also Symbian, BlackBerry, Windows Phone, iOS, and even comes as a Java MIDlet.

Unique Qualities

Each of the three browsers boasts some unique features as well. Chrome has the ever so useful Incognito mode, which allows you to stay untracked while surfing the Net. Firefox Browser inherited the Do-Not-Track feature and the Awesome Screen from its bigger brother. Opera, in its turn, provides server-side data compression, saving your money when you're using mobile data. This also sometimes leads to quicker page loading.

Differences in Menu Design

Wrap-up

Back to the main question then: which of these is more comfortable to work in? My personal choice is Opera Mini, mainly because of the navigation buttons (no matter how much I enjoyed the tab listing and Incognito mode in Chrome and how safer I felt with Do-Not-Track in Firefox). But I have to admit that Opera is the least secure among the three, so ultimately you should stick with a browser that suits all your needs, not just those of comfort and esthetics.
