Also describes 1) a edge scenario where class is used as mixin, then it should define a factory constructor and be abstract. 2) if the same message on 2 mixins is 'move' the 'move' on the rightmost mixin is called (and no other mixin's 'move', unless the rightmost 'move' calls 'super'.

A good example of this use case in Dart is the abstract HTML Element class, which defines dozens of named factory constructor functions returning different subclasses. For example, Element.div() and Element.li() return and elements, respectively.

connect, remote, ssh, vnc - 4 | id:958839 -

VNC exports a whole session, desktop and all, while ssh will run a single program and show its windows on your workstation. The VNC server exports a session that survives even when you disconnect your screen, and you can reconnect to it later with all the windows open etc. This is not possible with an ssh X tunnel, since when your X server dies, the windows go away. 1. That's the biggest reason I always use VNC, never direct X window. (I use VNC over a ssh tunnel). When I close the lid on my laptop, the connection is broken. With ssh -X, there is no way to resume -- I have to re-start the application from the beginning. With VNC (both direct and over a ssh tunnel), I can reconnect and resume. 2. If an actual GUI app is not required, and just basic shell access will do (e.g., xterm), then do “ssh“ followed by “screen bash“. If disconnected (laptop closed,vpn disconnected, etc), the remote shell stays active. Re-login & re-connect via “screen -r“. I only bring this up since I've seen people run vnc just for basic shell access (or run a remote xterm displayed locally); most of the time (but of course not always), simple shell access will suffice. @simona after the successful ssh login, then run screen: ssh user@host ; and after logged in: screen bash ; to disconnect, ctrl+a followed by ctrl+d. You can logout and login again, then: screen -ls and screen -r. Exiting bash exits the screen session. See screen tutorials

„(Očkování) zcela jistě snižuje přenos,“ uvedl Brooke k výsledkům studie. „Očkovaní lidé infekci přenáší v určitých případech, ale data ukazují jasně, že přenos u očkovaných je výrazně nižší než u neočkovaných lidí,“
