The idea here is that we use a Desktop PC for developing/debugging Raspberry Pi set-ups using qemu for emulating Rasperrby Pi.
qemu currently supports the following configurations:
This recipe is for setting virtualization on a voidlinux desktop.
Use this setup script to set things up on void linux.
Note that virsh and virt-manager commands connect to different libvirtd
sessions by defauult.
virsh defaults to qemu:///session while virt-manager to qemu:///system.
It is better …
This article is about erasing disc drives securely. Specially for SSD drives, writing zeros or random data to discs is not good enough and counterproductive.
One way to do secure erase (for disposal) is to begin with an encrypted disc. However, after the fact the following options are possible:
If you often mount and access a remote NFS share on your system, you will probably want to know how to improve NFS file access performance. One possibility is using file caching. In Linux, there is a caching filesystem called FS-Cache which enables file caching for network file systems such …
Telegram is a messenger designed to overcome the limitations of other messengers like WhatsApp or similar ones. It is different and better than other messengers on more than one level. A few of the important features that make it stand out among other messengers are:

So I finally moved my WordPress web sites to OpenShift.
OpenShift is a cloud based Platform-as-a-Service offering from RedHat. And while there is a learning curve I would say that so far it works great.
My implementation is a fully cloud based solution. Makes use of the following services:
Windows system administration is very mouse driven and to reach all tools you need to browse through Windows explorer.
If you are like me and prefer to log on a limited privilege account and use Runas to perform admin tasks, you can open these consoles with the .msc file names …
Software package download proxy
rpmgot is a simple/lightweight software package download proxy. It was designed to run on an OpenWRT router with some USB storage. So it is fully implemented as an ash script.
The basic idea has been implemented multiple times. For example refer to this article on …
In Linux, there is a caching filesystem called FS-Cache which enables
file caching for network file systems such as NFS. FS-Cache is built
into the Linux kernel 2.6.30 and higher. In order for FS-Cache to
operate, it needs cache back-end which provides actual storage for
caching. One such …
As usual with any IT system backups are important. This does not change when using a free shared hosting provider. Because it is free, one would argue it is even more important.
For my wordpress web site I used something called cli-exporter. It let's you create "Wordpress" export files from …
This is an interesting concept. Essentially is an Encryption dongle that encrypts stuff between your PC and your USB mass storage device.
I am still to test this recipe
First of all, we must install the following components:
