Using pipes as serial port for VirtualBox

Filed under
HowTos

While trying to reproduce and debug UnionFS bugs with VirtualBox, I needed to extract a copy of the call traces. Screenshots are not easily usable, so I tried the "serial ports" feature of VirtualBox.

An "Host Pipe" mode is available, to redirect serial port output to a pipe. But it didn't work by using a named pipe, created with mkfifo. Actually, if set to create the pipe, VirtualBox will create a UNIX local domain socket.

$ file /tmp/vbox-pipe
/tmp/vbox-pipe: socket

The "pipe" name is a bit ambiguous, it's easy to understand it as a fifo, not a socket (and actually, the Windows implementation uses a named pipe in VirtualBox...)

KDE: Simple by Default, Powerful When Needed

KDE (back when it was still the name of the desktop environment) and our applications historically stood for powerful features and great flexibility and customizeability. This is what our users love about our software, this is why they choose Plasma and KDE software instead of one of the other Free desktop offerings. And it is also something they would fight tooth and nail for if we wanted to take it away (as many a KDE maintainer who dared to remove a feature he thought was unnecessary can tell). Read more

BitTorrent Bleep alpha released for Android

As an alpha it still has some issues “As with any Alpha, there are some known issues and bugs to work out. Android users will need to set the app to “Wi-Fi Only” unless you have an unlimited data plan; this is only for the time being while we iron out and issue related to battery and data-plan. And while you can move a username from desktop to mobile, Bleep does not yet support moving an existing account from Android to the desktop. And while you can receive messages on multiple devices; messages sent will not be seen across all devices. As with our previous release, communications happen only when all parties are online – you cannot send offline photos or group chats asynchronously.” Read more
