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:
I am busy moving away from my VeraEdge installation to a Home Assistant running on a Raspberry Pi 4. This is because it looks like the maker of the VeraEdge was bought and it is slowly being phased out.
For this I am using the following parts:
This is my op script.
This is stupidly simple script to elevate priviledges in order to manage NFS shares on my QNAP NAS.
The idea is that NFS shares do squash-root so admin access is
disallowed through NFS. This gives a convenient way to issue
root level commands without using …
My ISP provider is KPN. They recently enabled IPv6 in my street. I was using before a IPv6 Tunnel Broker, starting with SixXS and after they went out, with Hurricane Electric. So naturally, I decided to switch to KPN's native IPv6 service.
They provide a /64 prefix, which is reasonable …
The point of this recipe is to create a encrypted file sytem so that when the disc is disposed, it does not need to be securely erased. This is particularly important for SSD devices since because of block remapping (for wear levelling) data can't be overwritten consistently.
The idea is …
Former United States President Dwight Eisenhower was responsible for putting together one of the most important yet fundamentally simple to understand concepts in time management. Eisenhower's Urgent/Important Principle is a tool to help decipher what tasks need to be addressed more immediately than others. Anyone who uses the principle …

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 …
It is possible to migrate the whole array to larger drives (e.g. 250 GB to 1 TB) by replacing one by one. In the end the number of devices will be the same, the data will remain intact, and you will have more space available to you.
Last weekend I had a small weekend project to move my All-In-One Printer/Scanner from my Xen host server to a spare NAS200 I had lying around. Since the NAS200 has a i486 compatible CPU, and I had been able to run a CentOS 5 distro before, I figure it …
The other day I came across this project. Looks an interesting idea. It is a project that lets you run unmodified Linux binaries on Windows. It is more similar to WINE than to for example coLinux. While I conceptually I understand how it would work at a low level, I …
Sometimes we need to connect two or more geographically distrubuted ethernet networks to one broadcast domain. There can be two different office networks of some company which uses smb protocol partially based on broadcast network messages. Another example of such situation is computer cafes: a couple of computer cafes can …
