Parsec (video game)

Parsec is a computer game for the Texas Instruments TI-99/4A. Perhaps the best-remembered of all TI-99/4A games, it is a side-scrolling shooter, programmed in 1982 by Jim Dramis (who also programmed the popular TI-99/4A games Car Wars and Munch Man) and Paul Urbanus.

Object

The player in Parsec pilots a spaceship through sixteen differently-colored levels of play which scroll horizontally over the screen. The objective is to avoid being shot by an enemy ship or colliding with any flying object. All ships must be shot.

Gameplay

Three waves of fighters attack, alternating with three waves of cruisers. Enemy ships enter the screen one at a time. A ship flying off the left edge of the screen wraps around to the right side and attacks again. A new fighter can appear with others still on the screen, whereas a new cruiser will not come until the previous one is destroyed. The fighters pose only the threat of collision, while the cruisers fire on the player's ship. The fighter types are named Swoopers, LTFs (Light Triangular Fighters), and Saucers. The cruisers are called Urbites, Dramites, and Bynites. Each level ends with an asteroid belt, in which columns of asteroids advance on the ship and must be avoided or shot. At the end of each asteroid belt, any remaining asteroids are cleared away and the color of the ground is changed, then a new wave of Swoopers begins. Starting with level 4, the Swoopers are preceded by a random number of Killer Satellites, which come without the usual computer warning.

Parsec (parser)

Parsec is a library for writing parsers in Haskell. It is based on higher-order parser combinators, so a complicated parser can be made out of many smaller ones. It has been reimplemented in many other languages, including Erlang, OCaml, F# and C#, as well as imperative languages such as Java.

Because a parser combinator-based program is generally slower than a parser generator-based program, Parsec is normally used for small domain-specific languages, while Happy is used for compilers such as GHC.

Gopher

Pocket gophers, commonly referred to as gophers, are burrowing rodents of the family Geomyidae. There are approximately 35 species of gopher living in Central and North America. They are commonly known for their extensive tunneling activities. Gophers are endemic to North and Central America.

The name "pocket gopher" on its own may be used to refer to any of a number of genera within the family. These are the "true" gophers; however there are several ground squirrels in the distantly related family Sciuridae that are often mistakenly called gophers as well.

Description

Gophers weigh around 0.5 pounds (230 g), and are about 6–8 inches (150–200 mm) long in body length, with a tail 1–2 inches (25–51 mm) long. A few species reach weights approaching 1 kg (2.2 lb). Within any species, the males are larger than the females and can be nearly double their weight.

Their lifespan is normally one to three years assuming no diseases or predation. The maximum life span for the pocket gopher is approximately five years. Some gophers, such as those in the genus Geomys, have lifespans that have been documented as up to seven years in the wild.

Gopher+

Gopher+ is a forward compatible enhancement to the RFC 1436 Gopher protocol. Gopher+ works by sending metadata between the client and the server. The enhancement was never widely adopted by Gopher servers.

How it works

The client sends a tab followed by a +. A Gopher+ server will respond with a status line followed by the content the client requested. An item is marked as supporting Gopher+ in the Gopher directory listing by a tab + after the port.
