So, no German Corona Warn App for me: my iPhone 6 Plus is stuck on iOS 12. And you need to be able to run iOS 13 (which came out last year) and above to run it. A shame.

I’m probably in the minority of iPhone users on such an old device, though. Still, I wonder how many people have a similar problem (at least Android devices only require Android 6, which is five years old). And how many people won’t even bother installing it.

Furthermore, the seemingly extraordinary high development costs of €20 million - plus an additional €48 million running costs until the end of 2021 - makes me wonder whether the money could have been used more wisely. Time will tell I guess.



Soundtrack for the weekend:

Body Count - Cop Killer (Live at Hellfest 2018)

Sepultura - Anticop (Live)


Here’s a Twitter thread (scroll up and/or down from the linked tweet) of some 300-plus-and-counting videos of police brutality: https://twitter.com/greg_doucette/status/1268391718086422528.

This is only from this past week.

Not any of these assaults is even remotely justified. Absolutely unbelievable – in the worst possible way. And this is just a small subset of the incidents that have been published or have even been recorded. Any single one of these violations on its own is outrageous! And all this is happening during peaceful protests against police brutality.


On the horrifying situation in the US

The current situation in the US is absolutely insane! In a lot of cities and areas police forces are violently attacking protestors and press. And their racist, evil, idiot president only keeps adding fuel to fire, insulting protestors and anyone else not getting in line with him. His recent speech was unbelievable: disrespectful and dangerous.

Rage Against the Machine – Killing in the name.

Body Count – No Lives Matter


Black lives fuckin' matter

How can one not sympathise with the #BlackLivesMatter movement? Generally, and especially right now. George Floyd was – unnecessarily, intentionally, almost casually – killed by a white police officer. And he was only the most recent case of many many many others in the past.

Just started bulk-loading another 30.5m-spool of APX 400.

I think this film bulk-loaded is the best deal in black and white film photography. One spool is €48 at Nordfoto and gives you 18 roles of film with 36+ exposures each. That’s not even €2.70 per canister. It’s a steal. And it’s a great film.



Some music I’ve been enjoying recently:

  • KATATONIA – “City Burials”. Their new album. What can I say? Of course, it’s great!
  • MONOLORD. Listening to all their 4 albums. It’s low, slow and heavy. And I like it.
  • PORTISHEAD – “Dummy”. Just a wonderfully quiet and melancholic album.
  • VLTIMAS – “Something Wicked Marches In”. All-Star Death Metal. David Vincent’s vocals are just superb!
  • CRAFT – Everything. This Swedish black metal act is growing on me.
  • SOEN – “Lotus” and “Lykaia”. Still regular listening to those albums.
  • OPETH – “In Cauda Venenum”. Ever since seeing them live last time, I can’t get “Allting tar slut” out of my head.
  • RUSSIAN CIRCLES – “Blood Year”. Their latest album. Would have loved to see them live last month. But as everything was cancelled, this will need to do – which is not bad at all.
  • TOOL – “Fear Inoculum”. Still in rotation.


Yesterday, I spontaneously acquired a new (used) darkroom enlarger that was on offer locally:

My new Kaiser VP-6000 enlarger in dim light projecting a image onto its base plate

It’s a Kaiser VP-6000. And it included everything I need to make prints from 6x6 medium format negatives. So now I can finally start printing the photos I have been making with my Rolleiflex!

As much as I like Jekyll, Liquid is bloody nonsense.

It’s probably just me.

But I find its strange syntax and very limited functionality so frustrating. I always wish I could just use plain Ruby and not have to struggle every time I want to do anything in my view templates.








It turns out, lazy loading does work with responsive images in Firefox 75: for this to work, you currently have to put the loading attribute before srcset in the attribute list of an img tag. This is a bug, and will be fixed in a future release.

So, I changed my markup accordingly – both on this site and the photo journal.

As for Firefox’ implementation itself: I find it currently too lazy. A new image is only downloaded when it’s already inside the viewport. This is going to result in visitors (unnecessarily) having to wait for an image download, especially when the image is larger and/or their internet connection is not the fastest.

Chrome’s implementation on the other hand is more appropriate in my opinion: it starts downloading images marked with loading=lazy well in advance – a few full “screens” before they are actually reached via scrolling.

Anyhow: happy this got implemented in Firefox now, too, despite its implementation needing a bit more refinement in my opinion.







This site now uses lazy-loading for the Youtube video embeds. Meaning, a preview image is loaded, and only when you click that is the actual video embed requested.

After posting a few Youtube videos to this site recently, I noticed this was loading a whole lot of quite large third-party resources. And this was happening without even playing a video – very likely resulting in visitors having to download a non-trivial amount of megabytes of no use. The site was slow to load. My Lighthouse score went way down.

So I fixed it.

To lazy load the videos I wrote a Jekyll plugin for a custom Liquid tag, that will take a Youtube video URL as parameter and spit out an iframe tag that uses its srcdoc attribute to at first only load the video’s preview image and display a “Play” button.



Grmpf. I just noticed my “Fuck you, Instagram!” bookmarklet became useless. Instagram won’t let you click and open an image from a person’s index page. They now immediately prompt you to log in. And while the bookmarklet currently still removes the log in modal, any further attempts on clicking an image are ignored. So, this current version does not work any longer. 😠

At least, one can still right-click and hit “Open Link in New Tab” (in Safari that is). But that’s pretty tedious.

I wish more people simply had a website or blog without this sort of nonsense.


Spent the evening working on this site a little bit:

  • Added article teaser images to index pages.
  • Made the “Read More” links more prominent.
  • Added OpenGraph og:image and og:type meta tags.
  • Adding loading="lazy" to the Youtube iframes.
  • Making the Youtube embeds grayscale on index pages unless you hover over the article.

So, here’s a drumcam video of Danny Carey playing “Pneuma” off the latest Tool album:

Seeing a drummer play songs live always makes you appreciate the skill even more than simply hearing it. Even with someone like him, where by merely listening it’s already immediately obvious that most people – including me – probably wouldn’t even be able to count this song correctly let alone play drums to it and keep a band playing together.

I also think it’s a first, I’ve seen that type of high-quality video of Danny Carey.

And great song by the way. My current favourite from “Fear Inoculum”.




My first ever pedalboard is taking shape:

My looper, phaser, fuzz, and octaver pedals on a pedalboard. An expression pedal on its right. And my feet at the bottom of the frame, featuring socks with cheeseburgers pattern.

In addition to the looper, the phaser, and the Little Big Muff fuzz I mentioned before, I now also got an EHX Pitch Fork and an expression pedal.

It’s all attached to the pretty much smallest pre-build board I could find: a Fame Spaceboard 50S.

And I think I now want to buy a single dedicated power supply, which can power all those pedals. Because it’s currently a little annoying having to power the pedals all individually.

Anyhow: happy progress!





Last week I discovered Royal Blood and was blown away! Just check out this festival gig:

They’re only a duo – a drummer and a bassist (!) – but produce an impressive (and innovative) sound. Have not seen anything quite like it. It’s like The White Stripes meet Muse and it’s brilliant!









I was actually thinking that I might have seen enough Opeth gigs by now. But no! Last night in Cologne was the best one I’ve been to (yet)! Great setlist, great light show, and – as always – great musicianship. Very happy we went.


It’s the time of year where I generally push my films to ISO 1600. And that means I now need to slightly readjust my brain again for guessing exposure.

And in April it’s all back to ISO 400 again.
