Light pen

A light pen is a computer input device in the form of a light-sensitive wand used in conjunction with a computer's cathode-ray tube display. It allows the user to point to displayed objects or draw on the screen in a similar way to a touchscreen but with greater positional accuracy. A light pen can work with any CRT-based display. A light pen detects changes in brightness of nearby screen pixels when scanned by cathode-ray tube electron beam and communicates the timing of this event to the computer. Since a CRT scans the entire screen one pixel at a time, the computer can keep track of the expected time of scanning various locations on screen by the beam and infer the pen's position from the latest timestamp; the first light pen was created around 1955 as part of the Whirlwind project at MIT. One of the first more deployed uses was in the Situation Display consoles of the AN/FSQ-7 for military airspace surveillance; this is not surprising, given its relationship with the Whirlwind projects. See Semi-Automatic Ground Environment for more details.

During the 1960s light pens were common on graphics terminals such as the IBM 2250, were available for the IBM 3270 text-only terminal. Light pen usage was expanded in the early 1980s to music workstations such as the Fairlight CMI and personal computers such as the BBC Micro. IBM PC compatible CGA, HGC and some EGA graphics cards featured a connector compatible with a light pen, as did early Tandy 1000 computers, the Thomson MO5 computer family, the Atari 8-bit, Commodore 8-bit, some MSX computers and Amstrad PCW home computers. For the MSX computers, Sanyo produced a light pen interface cartridge; because the user was required to hold their arm in front of the screen for long periods of time or to use a desk that tilts the monitor, the light pen fell out of use as a general purpose input device.

Caerns: Places of Power

Caerns: Places of Power is a supplement published by White Wolf Publishing in 1993 for the horror role-playing game Werewolf: The Apocalypse. Caerns: Places of Power is a 160-page softcover book designed by Emrey Barnes, Steven C. Brown, Phil Brucato, Alan Bryden, Sam Chupp, John Gavigan, Harry Heckel, Christopher Howard, Sam Inabinet, Izumi Hideo, David Key, Kenneth Meyer, James A. Moore, George Neal, Roderick Robertson, Ryk Strong, Teeuwynn Woodruff. Interior art is by John Bridges, Sam Inabinet, Scar Studios, Dan Smith, Ron Spencer, Joshua Gabriel Timbrook, Bryon Wackwitz, with cover art by Scott Hampton; the book describes fourteen sites of spiritual power, called "caerns", that are sacred to each of the tribes of the Garou. Locales range from Tibet to Arizona and Ireland; each entry has details of the history, important personalities, points of interest. In the May 1994 edition of Dragon, Rick Swan liked the details provided for each site, but he was disappointed by a lack of follow-up to good ideas: "The history of the Greek caern hints at a link between the Garou and Nazi Germany, but it’s left undeveloped...

A cannibal who operates a corner grocery store in Alaska — a great idea for a character if I heard one — is introduced tossed away." Swan thought, "The story hooks, many only a sentence or two, don’t amount to much." However, he concluded, "Despite its flaws, the sheer volume of ideas makes this a great resource for new campaigns." Valkyrie #1

Pacers–Pistons brawl

The Pacers–Pistons brawl, known colloquially as the Malice at the Palace, was an altercation that occurred in a National Basketball Association game between the Indiana Pacers and the defending champion Detroit Pistons on November 19, 2004, at The Palace in Auburn Hills, Michigan. The Associated Press called it "the most infamous brawl in NBA history."With the Pacers leading 97–82 and less than a minute left in the game, Pistons center Ben Wallace attempted a layup shot but was fouled hard from behind by Pacers small forward Ron Artest, now known as Metta World Peace. A furious Wallace shoved Artest, the benches emptied. After the fight was broken up, a fan threw a drink from the stands at Artest while he was lying on the scorer's table to cool himself down. Artest charged after the fan, sparking a massive brawl between players and spectators that stretched from the seats down to the court and lasted several minutes. After the game, the NBA suspended nine players for a total of 146 games, leading to the players losing $11 million in salary.

Five players were charged with assault, sentenced to a year of probation and community service. Five fans faced criminal charges and were banned from attending Pistons home games for life; the fight led the NBA to increase security between players and fans and limit the sale of alcohol in games. The meeting was the first between the two teams since the previous season's Eastern Conference Finals, which the Pistons won in six games en route to their first NBA title since the "Bad Boys" era of the late 1980s and early 1990s; this caused the game to receive much hype from the fans. Having won two games in a row, the Pacers came into the game with a 6–2 record, while the Pistons, the defending champions, began their season 4–3; the game was televised nationally on ESPN, as well as on the Pacers' and Pistons' local broadcast affiliates, Fox Sports Midwest and WDIV, respectively. The game, like many previous meetings between the two teams, was dominated by defense; the Pacers got off to a quick start, opening up a 20-point lead with seven minutes to go before halftime.

The Pistons managed trailing by 16 points by halftime. The Pistons opened the third quarter with a 9–2 run, but the Pacers ended it with a buzzer-beating three-pointer and a layup from Jamaal Tinsley heading into the fourth quarter. Richard Hamilton and Lindsey Hunter started the last quarter with consecutive three-point field goals, as the Pistons cut into the lead again, but Stephen Jackson's back-to-back field goals pushed the lead back to 93–79 with 3:52 remaining putting the Pistons away. Despite the lopsided score near the end of the game, most key players on both teams remained in the game; the Pacers were led by the 24-point effort of Ron Artest. Jermaine O'Neal notched a double-double with 13 rebounds. Tinsley had eight assists and a career-high eight steals. Hamilton led the Pistons with 20 points. Rasheed Wallace and Ben Wallace both recorded a double-double; the brawl began with 45.9 seconds remaining in the game, when Indiana led 97–82. Pistons center Ben Wallace was fouled from behind by Pacers small forward Ron Artest, who slapped him across the back of the head during a layup attempt.

Wallace said that Artest had warned him he would be hit. Wallace responded by shoving Artest in the face with both hands, causing players from both teams to get in between them as they attempted to keep Wallace and Artest separated. Pistons coach Larry Brown was not yet concerned, because fights in the NBA lasted for more than a few seconds. During the altercation, Artest laid down on the scorer's table to relax while putting on a headset to speak with Pacers radio broadcaster Mark Boyle; the microphone was not live. Boyle recalled that the broadcasting team knew Artest's personality and "there was no way we were going to put an open mic in front of Ron Artest in that situation". Pacers president Donnie Walsh stated that Artest was following advice he had received on how to calm down and avoid trouble in a volatile situation. After unsuccessfully attempting to break up the confrontation, referees prepared to eject various players before the game resumed. Sportscaster Mike Breen, calling the game for ESPN, believed Wallace would be ejected, while Bill Walton was of the opinion that Stephen Jackson should be ejected as well, for shouting at the Pistons players and aggravating the situation.

However, Breen expressed concern that, if ejected, Wallace would have to walk past the Pacers bench, which could have triggered another incident. Ninety seconds after Wallace shoved Artest, most of both teams' players and coaches were huddled at midcourt, attempting to calm down Wallace. While Artest was lying on the table, Wallace threw a towel at him, causing Artest to stand up before being held back by coaches. A spectator, John Green threw a plastic cup of beer at Artest, hitting him in the chest. Artest jumped off the table, ran into the stands, grabbed a man, Michael Ryan, who he mistakenly believed was responsible. Boyle stood up to try and hold back Artest and was trampled in the effort, suffering five fractured vertebrae and a gouge on his head. Jackson followed Artest into the stands and punched a fan, William Paulson, in the face in retaliation for the man throwing another drink in Artest's face while he was being restrained by other spectators.
