File system encryption in Alpine Linux
This is similar to my previous article Encrypting Filesystem in Void Linux but for Alpine Linux 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 ...
Raspberry Pi emulation with Qemu

voidlinux virtualization
This recipe is for setting virtualization on a voidlinux desktop. Use this setup script to set things up on void linux. Connecting to libvirtd 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. ...
Alpine Boot switcher
I boot from a USB boot drive using UEFI. Because of the UEFI boot, it just a matter of copying the files from the alpine ISO to a USB thumbdrive VFAT32 partition. Partition may be set to EFI (but this doesn't seem to be required). Since I would like to switch between different alpine versions, I wrote a script to let me have multiple alpine versions and ...
Encrypting FileSystem in Void Linux
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 that the boot/root filesystem containing the encryption ...
Installing Void Linux
I made the switch to void linux. Except for compatibility issues around glibc, it works quite well. Most compatibility I have worked around with a combination of Flatpaks, chroots and namespaces. The high lights of void linux: ...

Resizing a Linux RAID
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. Extending an existing RAID array In order to increase the usable size of the array, you must increase ...
Using a NAS200 as a Print server
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 would make a good server with low power consumption. For that I updated my NASCC firmware so that it would boot a USB key, and update my CentOS image creation script. This worked well, I was able to boot CentOS without that much effort altogether. I myself have an Epson Stylus CX5500 which unfortunately only comes with binary drivers. This was not much of a problem since the NAS200 has a i486 compatible CPU. I find this is relatively unique among different NAS models. Alas, the performance was quite disappointing. I should be used to the NAS200 underperforming. But really, this was truly sad. I did not bother to test the printing, but I did try scanning with it. Running scanimage to scan a single page was taking over 15 minutes before I hit Ctrl+C. It was an idea, but the results were so sub par. The only take-aways of this are: ...
