Arcade Machine Problem

by Dennis Payne

My son's cub scout den put together an arcade machine for the Build It pin. It worked great. Then the day of the Blue & Gold where we were demoing it, it didn't work. I ended up using my laptop instead of the intended machine. I have now set it up four times on three computers and have discovered the cause of the problem. The machine is running Fedora. It has only one user and he automatically logs in. It is running wayland. Gnome is configured to automatically start EmulationStation. From there you can launch Ostrich Riders or Super Tux Kart. (I wanted only open source games with two players simultaneous preferably cooperative but more games can be put on.) The problem occurs if the machine does not have a mouse plugged in. EmulationStation starts normally but launching either game brings up the login screen. Any idea why a mouse is required and how that restriction can be removed? -- Dennis Payne dulsi(a)identicalsoftware.com https://social.freegamedev.net/channel/dulsi

aging/free books for DNS,LDAP,TCP...*NIX+BSD

by Doug Mildram

"Old" books in some cases, but some protocols never age out! (some of below maybe did...) Free books on my desk here at work/WPI, if unwanted I'll end up tossing: (2005) Addison-Wesley "The Design and Implementation of the FreeBSD OS" I got glassy-eyed diving into most of this kernel,fsys,devices,IPC,etc gore. (2003) ORA/O'Reilly "DNS & BIND Cookbook" (bind8,9) Cricket Liu 200+ pg paperback (2003) ORA "LDAP System Administration" Gerald Carter 290pg paperback (1994) Addison-Wesley "TCP/IP Illustrated, Vol. 1" W. Richard Stevens 550pg hardcover (1990) Prentice Hall "UNIX Network Programming" W. Richard Stevens 750pg hardcover ( things like fork/exec ; basic I/O ; FIFO,IPC,Sockets,TLI...ending in rlogin :) TOO OLD (1993) ORA "sendmail" ( v8 ) too old AND too nasty, though I like the Intro sec1+2 titles "MUA vs MTA" and "Why is sendmail so complex?"
