For example, Mehrotra said the method they developed to beat Ms. Pac-Man could be used to help a company’s sales organization make precise predictions about which potential customers to target at a particular time or on a particular day. The system could use multiple agents, each representing one client, with a top agent weighing factors such as which clients are up for contract renewal, which contracts are worth the most to the company and whether the potential customer is typically in the office that day or available at that time.

The enemies in Pac-Man are known variously as "monsters" and "ghosts". Despite the seemingly random nature of the enemies, their movements are strictly deterministic, which players have used to their advantage. In an interview, creator Toru Iwatani stated that he had designed each enemy with its own distinct personality in order to keep the game from becoming impossibly difficult or boring to play. More recently, Iwatani described the enemy behaviors in more detail at the 2011 Game Developers Conference. He stated that the red enemy chases Pac-Man, and the pink enemy aims for a position in front of Pac-Man's mouth. The blue enemy is "fickle" and sometimes heads towards Pac-Man, and other times away. Although he claimed that the orange enemy's behavior is random, in actuality it alternates from behaving like the red enemy when at some distance from Pac-Man and aiming towards the lower-left corner of the maze whenever it gets too close to him.

pacman is a utility which manages software packages in Linux. It uses simple compressed files as a package format, and maintains a text-based package database (more of a hierarchy), just in case some hand tweaking is necessary.

p_search_any (aliased as p_sa) enables approximate matching by package or author/maintainer names containing the search term. The first argument to p_search_any, term, is the word or name to search for. The second argument tells the function what fields to search through: 1-"Maintainer", 1-"Author", 2-"Package", 3-"Version".

To master the game Ms. Pac-Man, Maluuba researchers assigned a number of AI agents different tasks, and created a system that allowed them to work collaboratively. Photo credit: Microsoft.

Firstly, ensure the package actually exists (and watch out for typos!). If certain the package exists, your package list may be out-of-date or your repositories may be incorrectly configured. Try running pacman -Syyu to force a refresh of all package lists and upgrade.

Otherwise known as the "split-screen level" or a "kill screen", the Map 256 Glitch is, when you make it to map 256, the right side of the screen turns into a jumbled mess of numbers and letters and the left side is normal. It is impossible to beat. In Ms. Pac-Man, the screen goes blank with nothing except Ms. Pac-Man and the ghosts appearing. This also happens in Jr. Pac-Man, except there are bits of the sprites of the houses and balloon in the cut-scenes. It also occurs in the Pac-Man Google Doodle as an Easter Egg. There is even a game based on this glitch.

Pac-Man has numerous sequels and spin-offs, including only one of which was designed by Tōru Iwatani. Some of the follow-ups were not developed by Namco either —including the most significant, Ms. Pac-Man, released in the United States in 1981. Originally called Crazy Otto, this unauthorized hack of Pac-Man was created by General Computer Corporation and sold to Midway without Namco's permission. The game features several changes from the original Pac-Man, including faster gameplay, more mazes, new intermissions, and moving bonus items. Some consider Ms. Pac-Man to be superior to the original or even the best in the entire series. Stan Jarocki of Midway stated that Ms. Pac-Man was conceived in response to the original Pac-Man being "the first commercial video game to involve large numbers of women as players" and that it is "our way of thanking all those lady arcaders who have played and enjoyed Pac-Man." Namco sued Midway for exceeding their license. Eventually, Bally Midway struck a deal with Namco to officially license Ms. Pac-Man as a sequel. Namco today officially owns Ms. Pac-Man in its other releases.

For the weekend of May 21–23, 2010, Google changed the Google logo on its homepage to a Google Doodle of a fully playable version of the game in recognition of the 30th anniversary of the game's release. The game featured the ability to play both Pac-Man and Ms. Pac-Man simultaneously. After finishing the game, the website automatically redirected the user to a search of Pac-Man 30th Anniversary. Companies across the world experienced slight drops in productivity due to the game, estimated to be valued at the time as $120,000,000 (approximately €95,400,000; £83,000,000). However, The Official ASTD Blog noted that the total loss, "spread out across the entire world isn't a huge loss, comparatively speaking". In total, the game devoured around 4.8 million hours of work productivity that day. Some organizations even temporarily blocked Google's website from workplace computers the Friday it was uploaded, particularly where it violated regulations against recreational games. Because of the popularity of the Pac-Man doodle, Google later allowed access to the game through a separate web page. On March 31, 2015, Google Maps added an option allowing a Pac-Man style game to be played using streets on the map as the maze.

Pac-Man was one of the first games developed by this new department within Namco. The game was developed primarily by a young employee named Toru Iwatani over the course of a year, beginning in April 1979, employing a nine-man team. It was based on the concept of eating, and the original Japanese title is Pakkuman (パックマン), inspired by the Japanese onomatopoeic phrase paku-paku taberu (パクパク食べる), where paku-paku describes (the sound of) the mouth movement when widely opened and then closed in succession.

Near the corners of the maze are four larger, flashing dots known as Power Pellets that provide Pac-Man with the temporary ability to consume the ghosts and earn bonus points. The enemies turn deep blue, reverse direction and usually move more slowly. When an enemy is eaten, its eyes remain and return to the center box where it is regenerated in its normal color. Blue enemies flash white to signal that they are about to become dangerous again and the length of time for which the enemies remain vulnerable varies from one stage to the next, generally becoming shorter as the game progresses. In later stages, the enemies go straight to flashing, bypassing blue, which means that they can only be eaten for a short amount of time, although they still reverse direction when a Power Pellet is eaten; starting at stage 19, the ghosts do not become edible (i.e., they do not change color and still make Pac-Man lose a life on contact), but they still reverse direction. There are also fruits, located directly below the centre box, that appear twice per level; eating it will result in bonus points (100-5,000).

One of the first ports to be released was the much-maligned port for the Atari 2600, which only somewhat resembles the original and was widely criticized for its flickering ghosts, due to the 2600's limited memory and hardware compared to the arcade machine, and several design and implementation choices. Despite the criticism, this version of Pac-Man sold seven million units at $37.95 per copy, and became the best-selling game of all time on the Atari 2600 console. While enjoying initial sales success, Atari had overestimated demand by producing 12 million cartridges, of which 5 million went unsold. The port's poor quality damaged the company's reputation among consumers and retailers, which would eventually become one of the contributing factors to Atari's decline and the North American video game crash of 1983, alongside Atari's E.T. the Extra-Terrestrial.

Allow this Pac-Man Ghost Lamp to light your way today. Shaped like the iconic Pac-Man ghost, this 8" tall lamp has two different modes. The "On" mode makes the light glide through 16 (count 'em!) different colors, so you no longer have to decide between Inky, Blinky, Pinky, and Clyde - you can have them all and more! The "Party" mode makes the color change sound-activated, and there's a sensitivity dial so you can tune it to the level of your audio experience. The lamp is powered via micro-USB so you can put it on your desk and let your laptop provide power. Basically, we can see no reason you wouldn't want to wakka wakka wakkaway with this cool product. (We're sorry.)

Steve Golson, one of the co-creators of the arcade version of the game, said there was a reason Ms. Pac-Man had to be simple to grasp yet nearly impossible to conquer: It was originally designed for arcade play, and they wanted people to keep dropping those quarters in.
In music, the Buckner & Garcia song "Pac-Man Fever" went to No. 9 on the Billboard Hot 100 charts, and received a Gold certification with over a million records sold by 1982, and a total of 2.5 million copies sold as of 2008. Their Pac-Man Fever album also received a Gold certification for selling over a million records. In 1982 "Weird Al" Yankovic recorded a song titled "Pac-Man", which is a parody of "Taxman" by the Beatles. The song was played on the radio but was not released on a record at the time due to a cease and desist letter sent by the attorneys representing the Beatles. The song is set to be released in 2017 as part of the 15-album box set Squeeze Box: The Complete Works of "Weird Al" Yankovic. In 1992, Power-Pill (an Alias of Aphex Twin) released Pac-Man — a techno tune which apart from a Breakbeat and a few vocals, consists entirely of samples from Pac-Man.

Warning: When installing packages in Arch, avoid refreshing the package list without upgrading the system (for example, when a package is no longer found in the official repositories). In practice, do not run pacman -Sy package_name instead of pacman -Syu package_name, as this could lead to dependency issues. See System maintenance#Partial upgrades are unsupported and BBS#89328.

For multiple packages use a space-separated list, or use additional IgnorePkg lines. Also, glob patterns can be used. If you want to skip packages just once, you can also use the --ignore option on the command-line - this time with a comma-separated list.

Some issues have been reported regarding network problems that prevent pacman from updating/synchronizing repositories. When installing Arch Linux natively, these issues have been resolved by replacing the default pacman file downloader with an alternative (see Improve pacman performance for more details). When installing Arch Linux as a guest OS in VirtualBox, this issue has also been addressed by using Host interface instead of NAT in the machine properties.

Besides the special section, each other in pacman.conf defines a package repository to be used. A repository is a logical collection of packages, which are physically stored on one or more servers: for this reason each server is called a mirror for the repository.

6 years after it release Nikoli renamed Kasan Kurosu as Pac man, and released the first Pac man/Pacman booklet. Since then 22 Pacman/Pac man booklets followed and static's show that over one million Pacman booklets have been sold. Pacman/Pac man Puzzles appear in 100 Japanese magazines and newspapers today, and the Pacman craze is in second place, right after Pacman. According to Nikoli, Pacman/Pac man was the top ranking puzzle till 1992 and only then was Pacman over taken by Pacman.

Warning: Only do this when certain that previous package versions are not required, for example for a later downgrade. pacman -Sc only leaves the versions of packages which are currently installed available, older versions would have to be retrieved through other means, such as the Archive. It is possible to empty the cache folder fully with pacman -Scc. In addition to the above, this also prevents from reinstalling a package directly from the cache folder in case of need, thus requiring a new download. It should be avoided unless there is an immediate need for disk space.
Celeste Boyett June 24, 2017 Great but the controls are a bit rough. All around, a classic brought back to life that's not overpriced. Good job! Full Review

The first person to achieve this score is Billy Mitchell of Hollywood, Florida, who performed the feat in about six hours. Since then, over 20 other players have attained the maximum score in increasingly faster times. As of 2016, the world record, according to Twin Galaxies, is held by David Race, who in 2013 attained the maximum possible score of 3,333,360 points in 3 hours, 28 minutes, and 49 seconds.

Sometimes there are multiple versions of a package in different repositories, e.g. extra and testing. To install the former version, the repository needs to be defined in front:

Google has launched an April Fool's Day version of Google Maps that allows users to play the classic arcade game Ms Pac-Man on real streets. Google Maps users on smartphones can access the game by opening up the Google Maps app and clicking the pink circle in the bottom right of the screen. The app transports you to a random location, turning the map blue and throwing you into a version of the game in which you must guide your yellow character around the map, eating up dots and avoiding the colourful ghosts.

It could also be that the repository containing the package is not enabled on your system, e.g. the package could be in the multilib repository, but multilib is not enabled in your pacman.conf.

The Pac-Man character appears in the film Pixels , with Denis Akiyama playing series creator Toru Iwatani. Iwatani himself makes a cameo at the beginning of the film as an arcade technician. Pac-Man also has a small cameo in the film Guardians of the Galaxy Vol. 2. The main protagonist, Star Lord, turns into the character to defeat the main antagonist Ego.

Pac-Man has a bug in it that prevents it from being completely finished. This bug occurs at the 256th board, where it will cause an overflow in the the 8-bit byte distinct values. As a result, the final board is unplayable, with the right half replaced by a series of garbled symbols and letters. The 256th and final level in Pac-Man cannot be finished due to corrupting map glitches. Contents How do you do this glitch?Edit It's extremely hard to do this glitch unless you have extreme patience and dedication. You have to play up to the 256th board which can take up to 6 hours of non-stop playing. You can also use an emulator and skip to it. Why does this glitch happen?Edit While probably not the first game to suffer from a kill screen, Pac-Man's is possibly the most famous. Pac-Man's level counter was a single byte, and could therefore store only 256 distinct values (0 to 255, so in this case, an unsigned datatype). Players who reached the 256th board would cause a buffer overflow, causing the data in other areas of the stack to be overwritten. The final board was unbeatable, with the right half replaced by a series of random symbols and letters. With most of the dots are gone, the game will think: "Okay, the number of pallets pac-man ate isn't enough, keep going." (directly from Wikipedia and other sites) How can I prevent this glitch? Edit You can't with normal arcade machine versions. Some versions, however, have a board reset after completing the 255th board, meaning you start again at the first board with your score staying the same as you left it before the reset. This allows you to continue with the game without being attacked by the bug. However, this is assuming that you would actually WANT to complete the game, and not encounter the glitch. also has a fix for the glitch. So what does this mean for me? Edit It means you can only get about 3,333,360 points. It means you can't play this game forever.

If you had installed a program manually without using pacman or a frontend, for example through make install, you have to remove it and all its files and reinstall properly using pacman. See also Pacman tips#Identify files not owned by any package.

If you find bugs (which is quite likely), please email them to the pacman-dev mailing last at with specific information such as your command-line, the nature of the bug, and even the package database if it helps. You can also post a bug to the Arch Linux bug tracker Flyspray. Be sure to file bugs under the Pacman project.

PAC-MAN seems like a natural fit for the Google homepage. They’re both deceptively straightforward, carefully hiding their complexity under the hood. There’s a light-hearted, human touch to both of them. And we can only hope you find using Google at least a quarter as enjoyable as eating dots and chasing ghosts. You know, without actually needing any quarters. Posted by Marcin Wichary, senior UX designer and developer

Why this is happening: pacman has detected a file conflict, and by design, will not overwrite files for you. This is a design feature, not a flaw.

The game has inspired various real-life recreations, involving either real people or robots. One event called Pac-Manhattan set a Guinness World Record for "Largest Pac-Man Game" in 2004. The business term "Pac-Man defense" in mergers and acquisitions refers to a hostile takeover target that attempts to reverse the situation and take over its would-be acquirer instead, a reference to Pac-Man's power pellets. The game's popularity has led to "Pac-Man" being adopted as a nickname, most notably by boxer Manny Pacquiao, as well as the American football player Adam Jones.
