A graphical user interface (GUI) is a human-computer interface (i.e., a way for humans to interact with computers) that uses windows, icons and menus and which can be manipulated by a mouse (and often to a limited extent by a keyboard as well).
GUIs stand in sharp contrast to command line interfaces (CLIs), which use only text and are accessed solely by a keyboard. The most familiar example of a CLI to many people is MS-DOS. Another example is Linux when it is used in console mode (i.e., the entire screen shows text only).
A window is a (usually) rectangular portion of the monitor screen that can display its contents (e.g., a program, icons, a text file or an image) seemingly independently of the rest of the display screen. A major feature is the ability for multiple windows to be open simultaneously. Each window can display a different application, or each can display different files (e.g., text, image or spreadsheet files) that have been opened or created with a single application.
An icon is a small picture or symbol in a GUI that represents a program (or command), a file, a directory or a device (such as a hard disk or floppy). Icons are used both on the desktop and within application programs. Examples include small rectangles (to represent files), file folders (to represent directories), a trash can (to indicate a place to dispose of unwanted files and directories) and buttons on web browsers (for navigating to previous pages, for reloading the current page, etc.).
Commands are issued in the GUI by using a mouse, trackball or touchpad to first move a pointer on the screen to, or on top of, the icon, menu item or window of interest in order to select that object. Then, for example, icons and windows can be moved by dragging (moving the mouse with the held down) and objects or programs can be opened by clicking on their icons.
Advantages of GUIs
A major advantage of GUIs is that they make computer operation more intuitive, and thus easier to learn and use. For example, it is much easier for a new user to move a file from one directory to another by dragging its icon with the mouse than by having to remember and type seemingly arcane commands to accomplish the same task.
Adding to this intuitiveness of operation is the fact that GUIs generally provide users with immediate, visual feedback about the effect of each action. For example, when a user deletes an icon representing a file, the icon immediately disappears, confirming that the file has been deleted (or at least sent to the trash can). This contrasts with the situation for a CLI, in which the user types a delete command (inclusive of the name of the file to be deleted) but receives no automatic feedback indicating that the file has actually been removed.
In addition, GUIs allow users to take full advantage of the powerful multitasking (the ability for multiple programs and/or multiple instances of single programs to run simultaneously) capabilities of modern operating systems by allowing such multiple programs and/or instances to be displayed simultaneously. The result is a large increase in the flexibility of computer use and a consequent rise in user productivity.
But the GUI has became much more than a mere convenience. It has also become the standard in human-computer interaction, and it has influenced the work of a generation of computer users. Moreover, it has led to the development of new types of applications and entire new industries. An example is desktop publishing, which has revolutionized (and partly wiped out) the traditional printing and typesetting industry.
Despite the great convenience of the GUI however, system administrators and other advanced users tend to prefer the CLI for many operations because it is frequently more convenient and generally more powerful1. On Unix-like operating systems, GUIs are actually just attractive, convenient coverings for command line programs (i.e., programs which operate from a CLI), and they rely on them for their operation.
One of the great attractions of Unix-like operating systems is that they have maintained their CLI capabilities while continuing to improve their GUIs, thereby allowing advanced users to harness the full power of the computer while simultaneously making it easier for beginning and intermediate users. In contrast, the newer versions of Microsoft Windows (such as 2000 and XP) have downgraded their CLIs to marginal roles.
Brief History
The origin of the GUI can be traced back to Vannevar Bush, a scientist and futurist who worked at the Massachusetts Institute of Technology (MIT) during World War II. In his now classic 1945 magazine article As We May Think, Bush proposed an information administration tool, the Memex, that would allow data to be stored on microfilm and made easily accessible, linkable with hyperlinks and programmable.
In 1963 Ivan Sutherland, a graduate student at MIT, developed a program for his Ph.D. dissertation called Sketchpad, which allowed the direct manipulation of graphic objects on a CRT screen using a light pen. His concept included the capability to zoom in and out on the display, the provision of memory for storing objects and the ability to draw precision lines and corners on the screen.
Douglas Engelbart, who had already been researching in human-computer interaction at Stanford University in the early 1950s, was greatly inspired by Bush's concepts. He unveiled the first primitive mouse in 1968 at the Fall Joint Computer Conference in San Francisco. Termed the X-Y Position Indicator, it was housed in a small wooden box with wheels, and it took the cursor with it on the display screen when it was rolled around on a horizontal surface.
Much additional progress occurred at Xerox Palo Alto Research Center (PARC), which Xerox Corporation established in 1970 in Palo Alto, California for the purpose of creating "the architecture of information" and "humanizing computers." This included developing the first usable GUI, which was incorporated into PARC's Alto computer. The Alto, which debuted in 1974, was envisioned as a smaller, more portable replacement for the mainframes that dominated computing at that time. However, it and its successor, the Xerox Star, never achieved commercial success, presumably due to their very high prices.
Steve Jobs, the co-founder of Apple Computer, was heavily inspired by the innovations at nearby PARC, and he thus decided to incorporate a GUI into his company's computers. Apple considerably extended PARC's work, including developing overlapping windows, manipulable icons, a fixed menu bar, dropdown menus and a trash can.
The Apple Macintosh, launched in 1984, was the first commercially successful use of a GUI. It was so successful, in fact, that the GUI was subsequently adopted by most other developers of operating systems and application software, and it is now used on (or at least available for) virtually all types of computers. Moreover, GUIs are employed in a wide range of other products as well, ranging from industrial controls to toys.
Microsoft announced development of its first operating system that incorporated a GUI in November 1983, and the initial version, Windows 1.0, was released in November 1985. Windows 2.0, released in December 1987, represented a major improvement over the primitive Windows 1.0 with its addition of icons and overlapping windows, but it was not until 1995 with the launching of Windows 95 that Microsoft was able to offer a relatively high quality GUI.
The Future
GUI design has made tremendous progress subsequent to the introduction of the Macintosh and Windows 95, and it is continuing to advance. This is the result of several factors, including advances in computer hardware (e.g., faster processors, more memory and higher resolution display devices), improvements in software and ever-greater demands by users and application developers.
A particularly important new application for GUIs in recent years has been browsers. In fact, browsers have come to rival the desktop metaphor (i.e., images representing files, folders and a trash can) that has characterized most general purpose GUIs to date. Other concepts are also being developed which could provide alternatives to the desktop metaphor.
One of the most interesting areas of exploration is GUIs that provide the user with the illusion of navigating through a three-dimensional space. Another area of research is increasing user control over GUI objects, such as being able to rotate and freely change the size and transparency of icons. Also being studied is the increased use of natural languages to interact with computers as a supplement or complement to GUIs.
---------------------------
1For example, CLI programs often offer more options than do their GUI counterparts, thereby providing greater flexibility of use. Also, multiple CLI commands can be combined using pipes to perform tasks that would be much more cumbersome to perform with GUI programs. In addition, the command line version of a program can sometimes to be used to perform a task when its GUI counterpart malfunctions or is not available.

Social network and banking scams are on the rise, says Cisco
Malware like Koobface and Zeus is replacing old-school phishing by Robert McMillan
What do phishing, instant messaging malware, DDoS attacks and 419 scams have in common? According to Cisco Systems, they're all has-been cybercrimes that were supplanted by slicker, more menacing forms of cybercrime over the past year.
In its 2009 Annual Security Report, due to be released Tuesday, Cisco says that the smart cyber-criminals are moving on.
"Social media and the data-theft Trojans are the things that are really in their ascent," said Patrick Peterson, a Cisco researcher. "You can see them replacing a lot of the old-school things."
Peterson is talking about attacks such as the Koobface worm, which spreads via Facebook and Twitter. Koobface asks victims to look at a fake YouTube video, which ultimately leads to a malicious download. Cisco estimates that Koobface has now infected more than 3 million computers, and security vendors such as Symantec expect social network attacks to be a major problem in 2010.
Another sneaky attack: the Zeus password-stealing Trojan. According to Cisco, Zeus variants infected almost 4 million computers in 2009. Eastern European gangs use Zeus to hack into bank accounts. They then use their networks of money mules to wire stolen funds out of the U.S. They have been linked to about $100 million in bank losses, some of which have been recovered, the U.S. Federal Bureau of Investigation said last month.
With that kind of success, older types of attacks such as instant messaging worms and phishing are now on the decline, Peterson said.
Traditional phishing is becoming harder as consumers become wary of suspicious banking sites and the banks themselves are now adept at getting these sites taken off the Internet.
Those factors make password stealing Trojans like Zeus even more popular, Peterson said. "They're focusing on other ways to basically accomplish the same thing."
One scourge that's not slowing down, however, is spam. Cisco expects spam volume to rise between 30 and 40 percent next year, even though countries such as the U.S. have knocked some spammers offline. In fact, U.S. spam dropped 20 percent in 2009, and the U.S. lost its traditional position as the world's number-one source of spam. More spam now comes from Brazil, Cisco says.

Apple customer collates 27-in. iMac display problems
Flickering, shattered screens lead iMac gripes, says data culled from Apple support forum by Gregg Keizer
A large number of problems with new iMacs, especially the top-of-the-line 27-in. model, has prompted one user to create a site that tallies issues ranging from cracked screens to flickering displays.
Canadian Web designer Scott Pronych created the Apple iMac (Fall 2009) Issues site to track the problems, in part because his new 27-in. Core i7-based iMac arrived with a broken screen. By digging through Apple's support forum, Pronych identified 343 different users who had reported problems with their new machines.
Cracked screens have garnered the most attention from bloggers and the media. On Apple's support forum, customers have reported receiving iMac displays with shattered glass, most of the time in the lower left corner of the screen. The bulk of the cracked-screen problems have been reported by people who purchased a new iMac equipped with Intel's Core i7 quad-core processor .
Apple unveiled the quad-core iMacs, along with revamped dual-core models in both 21.5- and 27-in sizes, on Oct. 20 as part of a broad product refresh that also debuted a redesigned MacBook and a new Mac mini-based server.
The cracked screen issue was actually low on the list, with just 54 incidents out of the 343, or 16%. The most widespread problem was a screen that flickered, "tore" or just went black: 179 cases, or 52% of the total.
"That shocked me, too," said Pronych today. "But the thread is huge."
The support thread Pronych referred to had more than 1,000 individual messages as of early Monday, with a view count of over 144,000, easily the most read of those on the iMac forum discussing problems.
"I have been experiencing some problems with the all new iMac 27-inch display," said Jan Sampermans , who kicked off the thread on Oct. 27. "Screen distortion/flicker somewhere random in the screen (feels like it is more in the lower part) that looks like a horizontal bar of about 2-3inches just popping in and out of the screen. Screen will go completely black for a second and then come back on. Sometimes 2-3 times in a row."
Although many users who reported the flickering said Apple had exchanged their iMacs, some noted that they had gone through as many as three machines before getting a defect-free system. Others complained about the solutions Apple support had suggested, or said they had run into roadblocks.
"[The second] iMac had dust underneath the glass and a dead pixel," said Minsoo Kim Sunday on the "New iMac 27inch screen flickering/tearing/shutoff" thread. "Since it was a cluster of dust, I had a valid reason for it to be swapped and again, drove 40 minutes to the Apple Store.
"There, the genius told me that without saying sorry for any inconvenience I may [have] had, 'Apple will not exchange any further iMac for minor screen problem like this.' I was shocked. In the first place, the best reason why I wanted iMac 27-in is the screen, so without this, why the **** would I spend money on this?"
Kim was eventually given a third iMac, but that one sported shattered glass.
Pronych, however, remained a loyal Mac user. "I got a replacement, and it's worked fine," he said. "I haven't encountered any of the other problems people have been reporting."
The flickering display problem is not limited to the quad-core iMacs; of the 179 total cases Pronych documented, 94 involve dual-core iMacs, while 85 involve an i5- or i7-powered iMac. More than 81% of all the problems he cited, however, were for the 27-in. model; relatively few reports of issues with the smaller 21.5-in. iMac have been posted on Apple's support forum.
According to Pronych's analysis, more-recent iMac production runs have not exhibited as many problems as the Week 46 and Week 47 batches.
Customers can log their problem with Pronych's Web site by filling out an online form .
Apple did not respond to a request for comment on the iMac issues that Pronych collated.

a. 375,000
b. 3,750,000
c. 37,500,000
d. 375,000,000
Answer key
Question 1: A new Windows problem has entered the geek lexicon. What is this one called?
Correct Answer: The Black Screen of Death
The BLSOD problem first appeared after a blog post by an obscure U.K. security firm called PrevX, which claimed Microsoft security patches caused some Windows PCs to seize up and display a blank (or black) screen. A few days later PrevX backed off those claims, saying it didn't know what (if anything) caused the problems. The reign of the original BSOD appears safe.
Question 2: The CrunchPad Web Tablet is dead. Which of the following is not one of the reasons given by its grieving poppa, Michael Arrington?
Correct Answer: Humility
In a not entirely surprising development, Arrington publicly declared the much-hyped, off-delayed Tablet dead-before-arrival after (he purports) his manufacturing partners decided they didn't actually need him. Because, we assume, hot air is cheap and easy to come by. The device was quickly buried after a brief yet tasteful ceremony.
Question 3: The top three search engines unveiled their lists of the most searched terms of 2009. Who's No. 1 with a bullet?
Correct Answer: Michael Jackson
The Gloved One topped Bing's list, beating out Twitter, swine flu, and Farrah. The King of Pop also reigned over Yahoo (beating out "Twilight" and Megan Fox) and was ranked the "fastest rising" search term by Google (ahead of Facebook and Tuenti, its Spanish equivalent). We always knew He would rise again.
Question 4: Not to be left out, Ask.com also published its own zeitgeist-seeking missive. Which of the following was the most frequently asked question of 2009?
Correct Answer: How much should I weigh?
It seems Ask.com has the fatties market sewn up. Other questions noted as answer choices topped the Pet, Celebrity Rumor, and "Is it real?" categories, respectively. Amazingly, nobody asked "what have you done with Jeeves?" That's what we really want to know.
Question 5: Psystar has struck a deal to settle its suit with Apple. What's it going to cost the company?
Correct Answer: $2.7 million
The Mac clone maker paid to settle a copyright suit filed by Apple, which it had been losing rather badly. Psystar also agreed to stop selling computers with the Mac OS pre-installed. But it held onto the right to sell "naked" Mac-compatible hardware and the Rebel EFI program, which theoretically would allow users to install the Mac OS on their own. The next legal battle will commence in three ... two ... one ...
Question 6: According to gossip site TMZ, adultery-friendly dating site AshleyMadison.com is seeking a new spokeshuman. Who just got offered $5 million to become the new face of cheatin'?
Correct Answer: Tiger Woods
The golf legend, who was recently accused of playing the greens of at least three women who are not his lovely wife, was offered a $5 million contract by the site whose motto is "Life is Short. Have an affair." Of course, offering Tiger $5 million is like offering Oprah a cookie -- it's not like the man needs more money. Then again, divorce attorneys can be expensive.
Question 7: "A crisis for news-gathering is not just a crisis for the newspaper industry. The flow of accurate information, diverse views and proper analysis is critical for a functioning democracy. We also acknowledge that it has been difficult for newspapers to make money from their online content. But just as there is no single cause of the industry's current problems, there is no single solution." Who's talking about how to cure the newspaper industry's woes?
Correct Answer: Google's Eric Schmidt
In a Wall Street Journal op-ed, the Google CEO outlined his "fantasy" for the digital news in 2015 and noted that, just as "video didn't kill the radio star," the Net won't kill newspapers. Or, to put it another way, newspapers will eventually turn into Howard Stern and Rush Limbaugh. Now there's a comforting thought.
Question 8: Just in time for Christmas, Comcast stopped by the media mall and picked up a few things for the kids. Which major television network did the cable giant just snap up?
Correct Answer: NBC
The No. 1 U.S. cable company (and second-largest ISP) bought 51 percent of NBC Universal from GE in a deal that values the peacock network and its cable stable (SyFy, Bravo, USA, MSNBC) at around $30 billion. Still to be determined: What will happen to the Sheinhardt Wig Co.?
Question 9: Facebook's 25-year-old CEO Mark Zuckerberg sent an open letter to all 350 million of his close personal friends this week. What did he announce?
Correct Answer: Facebook is adding new privacy controls
In his letter, Zuckerberg recapped changes Facebook originally announced in July that will let subscribers more finely control which of their friends can access each piece of content they post. Though Zucky's letter didn't address it, Facebook did announce plans to integrate its Connect service with Yahoo Mail and other Yahoo services. And Coca-Cola also debuted a creepy new app that lets you find your digital doppelganger on Facebook. However, there's still no sign of razor burns on Zuckerberg's boyish mug.
Question 10: Take the number of iPhone apps IDC predicts will be found in the wild by 2011. Multiply by the number of iPhones sold in its first two weeks at China Unicom's online iPhone store. Now divide that by AT&T's rank among the four largest U.S. telecoms in a recent customer satisfaction survey conducted by Consumer Reports. Put that on a color-coded map and banish it to the Island of Misfit Toys. What do you get?
Correct Answer: 375,000

a. 375,000
b. 3,750,000
c. 37,500,000
d. 375,000,000
Answer key
Question 1: A new Windows problem has entered the geek lexicon. What is this one called?
Correct Answer: The Black Screen of Death
The BLSOD problem first appeared after a blog post by an obscure U.K. security firm called PrevX, which claimed Microsoft security patches caused some Windows PCs to seize up and display a blank (or black) screen. A few days later PrevX backed off those claims, saying it didn't know what (if anything) caused the problems. The reign of the original BSOD appears safe.
Question 2: The CrunchPad Web Tablet is dead. Which of the following is not one of the reasons given by its grieving poppa, Michael Arrington?
Correct Answer: Humility
In a not entirely surprising development, Arrington publicly declared the much-hyped, off-delayed Tablet dead-before-arrival after (he purports) his manufacturing partners decided they didn't actually need him. Because, we assume, hot air is cheap and easy to come by. The device was quickly buried after a brief yet tasteful ceremony.
Question 3: The top three search engines unveiled their lists of the most searched terms of 2009. Who's No. 1 with a bullet?
Correct Answer: Michael Jackson
The Gloved One topped Bing's list, beating out Twitter, swine flu, and Farrah. The King of Pop also reigned over Yahoo (beating out "Twilight" and Megan Fox) and was ranked the "fastest rising" search term by Google (ahead of Facebook and Tuenti, its Spanish equivalent). We always knew He would rise again.
Question 4: Not to be left out, Ask.com also published its own zeitgeist-seeking missive. Which of the following was the most frequently asked question of 2009?
Correct Answer: How much should I weigh?
It seems Ask.com has the fatties market sewn up. Other questions noted as answer choices topped the Pet, Celebrity Rumor, and "Is it real?" categories, respectively. Amazingly, nobody asked "what have you done with Jeeves?" That's what we really want to know.
Question 5: Psystar has struck a deal to settle its suit with Apple. What's it going to cost the company?
Correct Answer: $2.7 million
The Mac clone maker paid to settle a copyright suit filed by Apple, which it had been losing rather badly. Psystar also agreed to stop selling computers with the Mac OS pre-installed. But it held onto the right to sell "naked" Mac-compatible hardware and the Rebel EFI program, which theoretically would allow users to install the Mac OS on their own. The next legal battle will commence in three ... two ... one ...
Question 6: According to gossip site TMZ, adultery-friendly dating site AshleyMadison.com is seeking a new spokeshuman. Who just got offered $5 million to become the new face of cheatin'?
Correct Answer: Tiger Woods
The golf legend, who was recently accused of playing the greens of at least three women who are not his lovely wife, was offered a $5 million contract by the site whose motto is "Life is Short. Have an affair." Of course, offering Tiger $5 million is like offering Oprah a cookie -- it's not like the man needs more money. Then again, divorce attorneys can be expensive.
Question 7: "A crisis for news-gathering is not just a crisis for the newspaper industry. The flow of accurate information, diverse views and proper analysis is critical for a functioning democracy. We also acknowledge that it has been difficult for newspapers to make money from their online content. But just as there is no single cause of the industry's current problems, there is no single solution." Who's talking about how to cure the newspaper industry's woes?
Correct Answer: Google's Eric Schmidt
In a Wall Street Journal op-ed, the Google CEO outlined his "fantasy" for the digital news in 2015 and noted that, just as "video didn't kill the radio star," the Net won't kill newspapers. Or, to put it another way, newspapers will eventually turn into Howard Stern and Rush Limbaugh. Now there's a comforting thought.
Question 8: Just in time for Christmas, Comcast stopped by the media mall and picked up a few things for the kids. Which major television network did the cable giant just snap up?
Correct Answer: NBC
The No. 1 U.S. cable company (and second-largest ISP) bought 51 percent of NBC Universal from GE in a deal that values the peacock network and its cable stable (SyFy, Bravo, USA, MSNBC) at around $30 billion. Still to be determined: What will happen to the Sheinhardt Wig Co.?
Question 9: Facebook's 25-year-old CEO Mark Zuckerberg sent an open letter to all 350 million of his close personal friends this week. What did he announce?
Correct Answer: Facebook is adding new privacy controls
In his letter, Zuckerberg recapped changes Facebook originally announced in July that will let subscribers more finely control which of their friends can access each piece of content they post. Though Zucky's letter didn't address it, Facebook did announce plans to integrate its Connect service with Yahoo Mail and other Yahoo services. And Coca-Cola also debuted a creepy new app that lets you find your digital doppelganger on Facebook. However, there's still no sign of razor burns on Zuckerberg's boyish mug.
Question 10: Take the number of iPhone apps IDC predicts will be found in the wild by 2011. Multiply by the number of iPhones sold in its first two weeks at China Unicom's online iPhone store. Now divide that by AT&T's rank among the four largest U.S. telecoms in a recent customer satisfaction survey conducted by Consumer Reports. Put that on a color-coded map and banish it to the Island of Misfit Toys. What do you get?
Correct Answer: 375,000

Invert colors
The Invert command inverts the colors in an image. You can use this command as part of the process of making an edge mask to apply sharpening and other adjustments to selected areas of an image.
Note: Because color print film contains an orange mask in its base, the Invert command cannot make accurate positive images from scanned color negatives. Be sure to use the proper settings for color negatives when scanning film.
When you invert an image, the brightness value of each pixel in the channels is converted to the inverse value on the 256‑step color-values scale. For example, a pixel in a positive image with a value of 255 is changed to 0, and a pixel with a value of 5 is changed to 250.
Do one of the following:
Choose Image > Adjustments > Invert.
Choose Layer > New Adjustment Layer > Invert. Click OK in the New Layer dialog box.
