Native VNC client
In order to connect to VMs remotely, several options exist. Using VNC is one way to go. Virtualization solutions like Qemu/KVM have built-in support, so a native VNC client on Genode becomes handy. In this post I'm going to report about a ported VNC client of the libvncserver project and its usage on Sculpt 20.02. Continue...

CPU affinity with Sculpt OS
With the latest 20.02 Sculpt release we added support to configure the affinity and number of CPUs available to components running on Sculpt. The principal support was already part of the Genode framework since 13.08, but missed to be easily usable on previous Sculpt versions. Continue...

Screencast on Sculpt OS
From time-to-time the screen cast support on Genode pops up. Martin successfully ported avconv and demonstrated it back then in 2016. In the event of Sculpt OS, I lately had the chance to update the port and integrate it with Sculpt OS in form of packages ready for use. The following instructions will guide you through the setup. Additionally a short video recorded running on Sculpt is available. Continue...

Graphical CPU utilization and monitoring tool (19.12)
The top_view component is a tool using the tracing infrastructure of Genode to gather thread related information, e.g. execution time, and prepare them for graphical presentation. Lately the tool got some updates I want to share. Beside the textual post I also uploaded a short tutorial video. In order to test the current version, you will have to build the Sculpt OS image yourself. Continue...

Graphical CPU utilization and monitoring tool
The top_view package is a tool using the tracing infrastructure of Genode to gather thread related information, e.g. execution time, and prepare them for graphical presentation. I already develop it for a while beginning with the early Sculpt versions. In the last weeks I extended it in my leisure time with some extra features, with the goal to selectively monitor behaviour of components of interest over some time. The main impulse was triggered during the work on audio on Sculpt, where I missed a basic online tool that supports me to get better insights into some behaviour of the system. Continue...

Disposal browser VMs
Since the early beginning of Sculpt I host and maintain two packages for running an up-to-date Firefox as VM. My main motivation is to have the door to the Internet out-of my "work" VM, which contains all sorts of sensible data. Continue...

Native audio with Sculpt VC
On the way back of FOSDEM 2019 I recognized that I missed to setup audio for my Sculpt VC machine. I used it already with Sculpt TC, but somehow I never took the time to re-integrate it with Sculpt VC. The next days after the FOSDEM trip I consulted my personal audio advisor -Josef- how to setup things. Continue...

Locking up your Sculpt VC screen
Using Sculpt on my working machine as day-to-day OS became quite comfortable. Still, some inconvenient stayed. One specific one appeared whenever I started for lunch - I wanted to lock the screen. Currently, this functionality is missing - because of that I had to power down my machine during lunch. Obviously, this is annoying - so I started to investigate how to solve the issue. Continue...
