when we pull ubuntu image then it have different kernel No it does not: it does not have the kernel part: it relies on the kernel of the host (the one running docker engine) for all system calls. As mentioned in “Docker vs Virtualization“: Initially Docker was built as an abstraction layer on top of … Read more

It is possible to achieve smooth scrolling VirtualizingStackPanels in WPF 4.0 without sacrificing virtualization if you’re prepared to use reflection to access private functionality of the VirtualizingStackPanel. All you have to do is set the private IsPixelBased property of the VirtualizingStackPanel to true. Note that in .Net 4.5 there’s no need for this hack as … Read more
You can find tons of example of WindowsServiceCore-based applications in StefanScherer/dockerfiles-windows You need to write a Dockerfile (like for instance diskspd/Dockerfile where you copy/unzip/install the application you need.

A lot of the research on this is dedicated to detecting so-called “blue pill” attacks, that is, a malicious hypervisor that is actively attempting to evade detection. The classic trick to detect a VM is to populate the ITLB, run an instruction that must be virtualized (which necessarily clears out such processor state when it … Read more
As wikipedia knows in its Context switch article, “context switch is the process of storing and restoring the state (context) of a process so that execution can be resumed from the same point at a later time.“. I’ll assume context switch between two processes of the same OS, not the user/kernel mode transition (syscall) which … Read more
The official mysql image stores data in a volume. Normally this is desired so that your data can persist beyond the life span of your container, but data volumes bypass the Union File System and are not committed to the image. You can accomplish what you’re trying to do by creating your own mysql base … Read more
There are two techniques that might be a big help. Both of them are described very well by Bea Stolnitz on her blog. The first is UI Virtualization and the second is Data Virtualization In UI virtualization you use things like VirtualizingStackPanel to make the UI draw fewer things. Data virtualization makes sure you don’t … Read more
