A think I’ve sort of solved the problem with webmentions. The remaining problem now is that it appears to arrive as a plain mention and not as a reply.

Apparently I broke webmentions when I created my new blog theme. By breaking them I mean they are sent anonymously.

I do remember solving this ones for my old theme but I don’t remember what the root cause and solution was. 😞

Damn the torpedoes. Allow me to present, a work in progress – and absolutely not finished, a new look of my blog.

The making of a new blog theme

One of the best signs of spring and summer is that I get the urge to tinker with my blog. Right now I’m going through very old posts and making sure that the images in them aren’t broken. Also, I think I’m going to redo the blog’s theme from scratch.

Here’s some thought I wrote down for myself late yesterday.

The Raspberry Pi Camera module does seem to work for the music player, but it did cause me some headaches initially.

The first problem I encountered seemed to stem from a sloppy physical installation of the camera. Once I removed it from the Pi and inserted it back in, it worked.

The second problem seems to be that by default the camera cropped the sensor data, so the QR code couldn’t be read as close to the camera as I wanted. Adding --prescale=640x480 as and argument to zbarcam appears to have solved the problem.

Tomorrow I’ll try using the HiFi Berry Amp2 as well.

Two weeks ago I was away on a work trip and I decided to try to capture footage to potentially make a vlog out of. Here’s some lessons I learned.

So no, there won’t be a finished vlog this time but is was fun to try.

Incredibly useful! ffmpeg and a bit of command line experience is super useful when dealing with video.

I’m working on a spatial audio mix for a VR/360 video. A fun project but I’m constantly reminded of how immature the tools are and how much of my time is spent fiddling with the setup rather than mixing.

But then again, fiddling with the tools is hard to do and I’m good at it so it is at least part of the reason why I get paid for doing this.

One of my projects at work today has been to make this, a system for playing back a recording of a ukulele through a surface transducer and then have it use an actual ukulele as a resonance cavity.
