Mounting an LVM-based NTFS Partition on the Linux Host

I use LVM or “Logical Volume Manager” for all my storage needs. LVM provides a layer of abstraction between physical storage devices (such as hard drives or SSDs) and the file systems that are created on them. Among the file systems are also NTFS partitions that I created under Microsoft Windows 10. Here I share a little BASH script that mounts an LVM-based NTFS partition on the Linux host.

Nikon Z8 Bird Detection

Last Saturday I got a chance to quickly try out Nikon’s new firmware 2.0 release for the Nikon Z8 mirrorless camera. I was anticipating this firmware upgrade since the firmware upgrade to the Nikon Z9 flagship camera.

The following are my first impressions of the new bird detection feature in the Nikon Z8 and how it can help capture sharp, in-focus photos of birds. This review is by no means comprehensive and doesn’t even address BIF or “birds in flight”. Yet I believe it may be helpful in determining Nikon’s improvements in the focusing department.

Nikon Try This

I just watched Matt Granger’s “The Problem with Nikon Mirrorless…” YouTube video and thought to myself how simple it would be to solve the Nikon focus issues with birds/animals/people detect. The Nikon Z9, Z8, Z7 II and basically all Nikon mirrorless cameras have, under certain circumstances, difficulties in focusing on the subject.

Admittedly it’s much easier to criticize than to actually fix something. However, here I’m trying to come up with a solution.

Script to Dump xml Configuration Files

Most people today use the libvirt API and/or its front end Virtual Machine Manager (virt-manager) to configure and manage virtual machines. Both create xml configuration files. Unfortunately you can’t just copy them or edit them using your favorite editor.

12 Years GPU Passthrough

Time flies. 12 years have passed since I built my first PC with GPU passthrough. Back in the old days there was little documentation on how to do it. I found a tutorial written for Fedora, plus some messages here and there. VGA passthru, as it was often called, was very restrictive. You had to have the right hardware to make it work, including a graphics card that was supported (like the Nvidia Quadro series).

Sharing Files between the Linux Host and a Windows VM using virtiofs

I often transfer files between my Windows virtual machine (VM) and my Linux host. Up until now I used a Samba server on the Linux host, with the Windows guest connected via a network bridge. That worked great and never gave me any problems.

Recently I tried out the new virtio-fs shared file system that allows you to share a folder on the Linux host with a Windows or Linux guest. Before you rush and follow my tutorial below, check out the “Performance” and “Conclusion” sections at the end. Here is my tutorial:

Choosing a Camera System

Whether newcomer, enthusiast, or professional photographer, I bet you’ve run into the dilemma of choosing a camera and lenses, or switching your current system to another brand. It may even be more far reaching, such as choosing a different technology.

Manjaro Update 2023-12-01 and the XFCE Desktop

Yesterday I updated my Manjaro Linux host and ran into a problem (it likely started already with update 2023-11-28). At boot, after I logged in, the desktop background would not change to my chosen picture and no desktop icons would appear. Also, when clicking the file browser, it wouldn’t open. After nearly 30 seconds the desktop background changes and the icons appear. Also, the file browser opens.

Does the Linux NTFS3 Driver Corrupt Directories?

Updated January 19, 2024

About a year ago I switched to the new Linux NTFS3 driver built into the kernel. Up until then I used the user space NTFS-3G driver to mount Windows NTFS drives on my Linux host. Yesterday when running my hash script on one of my NTFS photo backup drives, I noticed an input/output error.

The Importance of Choosing the Right USB Cable

Updated March 28, 2024

I already wrote about my trip to Spain and Europe and choosing the camera. Traveling with the Nikon Z7 II was definitely the right choice for me. What I haven’t mentioned was that I packed the wrong USB cable.
