NAME login – begin session on the system SYNOPSIS login [-p] [-h host] [username] [ENV=VAR…] login [-p] [-h host] -f username login [-p] -r host DESCRIPTION The login program is used to establish a new session with the system. It is normally invoked automatically by responding to the login: prompt on the user’s terminal. login may be special to the shell and may not be invoked as a sub-process. When called from a shell, login should be executed as exec login which will cause the user to exit from the current shell (and thus will prevent the new logged in…

NAME systemd.resource-control – Resource control unit settings SYNOPSIS slice.slice, scope.scope, service.service, socket.socket, mount.mount, swap.swap DESCRIPTION Unit configuration files for services, slices, scopes, sockets, mount points, and swap devices share a subset of configuration options for resource control of spawned processes. Internally, this relies on the Control Groups kernel concept for organizing processes in a hierarchial tree of named groups for the purpose of resource management. This man page lists the configuration options shared by those six unit types. See systemd.unit (5) for the common options of all unit configuration files, and systemd.slice (5), systemd.scope (5), systemd.service (5),…

Online gaming has never been stagnant for very long. What began as a relatively simple experience, often limited by slow internet connections and basic hardware, has evolved into a vast digital ecosystem that connects millions of players around the world. Today’s games are faster, more accessible, and more interactive than many people could have imagined a decade ago. Technology sits at the center of that transformation. Advances in connectivity, mobile devices, cloud computing, artificial intelligence, and platform design have reshaped not only the games themselves but also the way people discover, access, and enjoy them. As technology continues evolving, player…

Money has always depended on trust. What is changing is where that trust comes from and who controls it. New decentralized systems are challenging long-standing assumptions about how financial services should work, who gets access, and who holds the power. The Shift Away From Traditional Gatekeepers For decades, financial activity flowed through a relatively small number of institutions. Banks processed payments, approved loans, stored assets, and verified transactions. Most people accepted that arrangement because there were few practical alternatives. That assumption is being tested. Decentralized networks allow users to move value, exchange assets, and interact with financial tools without relying…

NAME ps2ps, eps2eps – Ghostscript PostScript "distiller" SYNOPSIS ps2ps [ options ] input.ps output.ps eps2eps [ options ] input.eps output.eps DESCRIPTION ps2ps uses gs(1) to convert PostScript(tm) file "input.ps" to simpler, normalized and (usually) faster PostScript in "output.ps". Normally the output is allowed to use PostScript Level 2 or Level 3 constructs, but the -dLanguageLevel=1 option restricts the output to Level 1. eps2eps performs the equivalent optimization for Encapsulated PostScript (EPS) files. Both accept any general Ghostscript command line options, and respectively options specific to the pswrite and epswrite devices. FILES Run "gs -h" to find…
