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.Continue reading “Manjaro Update 2023-12-01 and the XFCE Desktop”
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.Continue reading “Does the Linux NTFS3 Driver Corrupt Directories?”
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.Continue reading “The Importance of Choosing the Right USB Cable”
Can an AI chat bot like ChatGPT understand and explain program code, or even write its own code based on your directions?
Everybody (almost) is talking about artificial intelligence (AI). I wanted to see if ChatGPT, a large language model-based chatbot developed by OpenAI, is able to help in coding. Can ChatGPT evaluate and improve program code? Or can it even write its own program code, based on the task you set forth?Continue reading “ChatGPT for Coding”
Update January 27, 2023: The issue described below is limited to users of RAW partitions. But there is a workaround. See under “What to do?”
A recent update from QEMU 7.1 to QEMU 7.2 caused my Windows 10 VM to show 100% utilization of the C: drive. Performance of the Windows VM dropped to the bottom – the VM was pretty much unusable.
Users at the VFIO Reddit reported similar issues. However, as it turned out, it seems to affect only storage on LVM raw volumes. In other words, if you have your VM in a qcow file, all should be well.Continue reading “QEMU 7.2 and Raw Disks”
Half a year ago I replaced my Canon R5 and RF lenses for the Nikon Z7 II and some selected Z mount lenses. Both mirrorless cameras feature a 45 MP sensor, weather sealing, and are in many ways comparable. But a closer look shows substantial differences between both cameras and lenses.
This Nikon Z7 II review attempts to not only show the pros and cons of the camera and the lenses I own or used, but I feel also able to compare it with the Canon R5 and some Canon lenses. I will also share some impressions on how the Nikon Z7 II works with the FTZ-II adapter and the Nikon 200-500mm/f5.6 F mount lens.Continue reading “Nikon Z7 II Review”
Yesterday I finally decided to part with my Canon gear. I tried everything to make it work but it doesn’t work for me. See my Canon EOS R5 Disappointment post.
So, the first thing I thought a potential buyer of a camera might want to know is the shutter count. It is kind of the milage of the camera. Mechanical shutters have a maximum life expectancy that is published by the camera manufacturer. My Canon EOS R5 has an impressive shutter life of 500,000 actuations. That is a lot even for a professional camera body. Compare that to the shutter rating of the Nikon D850 with a mere 200,000 shutter actuations.Continue reading “Canon: Why Make Shutter Count Inaccessible?”
Update: October 4, 2023
My Canon and Nikon cameras use either the exFAT file system or the (older) FAT file system for image storage on their SD, SDxx, CF, CFexpress or XQD cards. In theory, the exFAT file system supports accurate time stamps up to a precision of 10 milliseconds. The FAT32 file system, in contrast, just offers 2 second accuracy for the modification time, or 10 millisecond for the creation time.Continue reading “Camera Manufacturers: Please Use Accurate Time Stamps for Image Files”

Two and half years ago I wrote a Nikon D700 Review (and D850 Preview) that – for most potential buyers – came a little late. The D700 was long taken off the shelves, replaced by newer models. This time I try to be a little faster and post my Nikon D850 review when this camera is still sold.Continue reading “Nikon D850 Review”

In March 2021 I did it: I bought a new camera, and it wasn’t a Nikon! Not that I never owned other cameras. I’m loyal to my wife, not to my camera gear.
I was looking for a way to reduce weight when hiking. At first I bought a Nikon Z6 II and lenses but wasn’t happy with the focus system and switching between rear display and EVF. While on a hike I missed a good opportunity to shoot low flying eagles because of these two issues. To be fair, I had the “cheap” 24-200mm lens mounted, not some top glass. And I had practically no hands-on experience with that camera. Within a few days I returned the equipment and – after all the recommendations, positive reviews as well as out of curiosity – I jumped to the “other” side: I bought the Canon EOS R5 and an assortment of lenses.Continue reading “Canon EOS R5 Disappointment”
