Yesterday, I gave some PhD dissertation advice. Today, I will present some tips for PhD candidates ready for public defense. In Norway, the public defense is a formal event with colleagues, friends, and family present—we typically also stream them on YouTube. The good thing is that when you are ready for the defense, the dissertation has already been accepted. Now it is time to show lecturing skills in the trial lecture and the ability to engage with peers in the disputation....

I am supervising several PhD fellows at the moment and have found that I repeat myself in the one-to-one meetings. So I will write blog posts summarizing general advice I give everyone. This post deals with what a PhD dissertation should look like. The classic Ph.D. dissertation Dear PhD fellow (in Norway, PhD fellows are employees, not students): All dissertations are different, yours included. You can write it however you want as long as it is good!...

As part of my year-long StillStanding project, I post an average image of the spherical video recordings on Mastodon daily. Average images The average image is similar to an “open shutter” technique in photography; it overlays all the frames in a video. The result is an image that shows the most prominent parts of the video recording. This is ideal for my StillStanding recordings, because the technique effectively “removes” objects that appear in the recording for a short period of time....

As part of my #StillStanding project I need to handle a lot of video files on a daily basis. Today, I wanted to check the duration and pixel dimensions of a bunch of files in different folders. As always, I turned to FFmpeg, or more specifically FFprobe, for help. However, figuring out all the details of how to get out the right information is tricky. So I decided to ask ChatGPT for help....

I often come across texts that confuse the concepts of notes and tones. Thus this little blog post that I can refer people when explaining the difference. While the terms “note” and “tone” may be used interchangeably in casual conversation, they have distinct meanings from a music theoretical perspective: Note: A note refers to a symbol in musical notation that tells the musician which pitch to play and for how long....

For my year-long StillStanding project I am generating videograms for all the scenes. Since there is not much motion in these 10-minute recordings, they typically look like stripes. Looking at today’s recording of an unspectacular hotel room in Kongsberg, I noticed how different the horizontal and vertical videogram look: It is fascinating how two averages of the same video recording can be so different. The explanation is simple; they are based on averaging in two different dimensions (horizontal and vertical)....

People often refer to “sound and video” as a concept pair. That is confusing because, in my thinking, “sound” and “video” refer to very different things. In this post, I will explain the difference. Sound and Audio In a previous blog post, I have written about the difference between sound and audio. The short story is that “sound” refers to the physical phenomenon of vibrating molecules, such as sound waves moving through air....

Today, I am halfway through my year-long #StillStanding project. Not so much has changed since I summed up the first 100 days. I still enjoy the experience, and there are new things to learn every day. Here is a 10-minute video I have recorded that presents the project, explains its rationale, and reflects upon some experiences so far: The biggest challenge moving forward is finding new spaces every day. I have already stood in the most accessible spaces, so I need to spend more time looking for unexplored rooms both at the university and close to my home....

I read somewhere (but never stored the link) that people should add a more lengthy description in their trip notes (or vacation messages or whatever people call it) and decided to try it. Usually, I have only added a very brief message about when I return, but I think the point of adding a longer one is to explain why one cannot be as accessible as one usually may be....

I’m sitting in my office, listening to the noisy ventilation system that inspired my AMBIENT project. Here is a short sample: At the moment, I am primarily focusing on completing my book Still Standing. However, as part of my year-long #StillStanding project, I have also started thinking about the sounds found in indoor environments. Asking ChatGPT for help I have yet to begin a proper literature review on ventilation noise, but as a start, I asked ChatGPT for help....
