Abstract: Disclosed are a method, a computer device, and a non-transitory computer-readable record medium to display activity time information of a chatroom. An activity time information display method may include receiving a user request for activity time information of a chatroom related to an instant messenger from a user of the computer device for the chatroom related to the instant messenger and displaying the activity time information of the chatroom on a chatroom-related screen of the chatroom in response to the user request.

Abstract: A bot-based role-playing method performed by a computer device comprising at least one processor configured to execute computer-readable instructions in a memory, includes: receiving, by the at least one processor, a script for an openchat; and creating, by the at least one processor, at least one character bot for role-playing in the openchat by learning at least one character included in the script through an artificial intelligence (AI) language model.

Abstract: Disclosed are a method, a computer device, and a non-transitory computer-readable record medium for sharing content created in another chatroom. A content sharing method may include receiving content created based on a message in a chatroom of another openchat as content of the other openchat set in openchat; and providing the content of the other openchat through at least one page of the openchat.

Abstract: A circuit that determines the remainder of a modulo 2 polynomial division in just one clock cycle. Specifically, each term of the remainder is determined in parallel with each other term of the remainder. The circuit includes a network of XOR devices to determine H(X)=P(X) mod G(X), where P(X) is a first binary polynomial, of a form: a.sub.m X.sup.m +a.sub.m-1 X.sup.m-1 30 . . . +a.sub.0, where a={0,1} and X={0,1}; G(X) is a second binary polynomial, of a form: a.sub.n X.sup.n +a.sub.n-1 X.sup.n-1 +. . . +a.sub.0, where a={0,1} and X={0,1}, and m>n; and H(X) is a third binary polynomial, of a form: b.sub.p X.sup.p +b.sub.p-1 X.sup.p-1 + . . . +.sub.0. The configuration of the network of XOR devices is determined by reducing terms of the first binary polynomial to have only terms having less than the degree of the second binary polynomial. Then, for each term of the third binary polynomial (i.e., the remainder), it is determined which reduced terms of the first binary polynomial affect it.
