Back in December 2019, I asked that someone took care of providing AppImages packages for Darktable. The obvious benefit would have been enabling early testing, prior to release, from people who can’t build the source code themselves, as to hopefully provide early feedback and help debugging before releasing. This has never been a priority, which means that it was ok to have a pre-release and a post-release rush to fix bugs.

Ansel inherits from Darktable its database backbone: the non-destructive editing histories are saved per-picture into an SQLite database, along with metadata and other user-defined data. Making the database aware of new pictures is done through “importing” pictures from a disk or a memory card. That’s where the import tool comes.
Unfortunately, the Darktable importer is another thing that was butchered circa 2020 and turned into something deeply disconcerning, as it is a file browser that resembles no previously-known file browser, and manages to lack basic features (like Ctrl+F or EXIF preview) while still being bloated with useless ones (see below). This is where we loose many a future user, and it is only step 0 of the workflow. What a great showcase of what a “workflow app” can do !
I have thought, for a very long time, that there was some kill-switch mechanism on the pixel pipeline. The use case is the following :
In that case, you want to kill all active pipelines because their output will not be used, and start recomputing everything immediately with new parameters. Except Darktable doesn’t do that, it lets the pipeline finish before restarting it, and looking at the comments in the source code, it seems to be a fairly recent regression and not the originally intended behaviour.
Darktable has its own GUI widgets library, for sliders and comboboxes (aka drop-down menus or selection boxes), called Bauhaus (in the source code, it’s in src/bauhaus/bauhaus.c). While they use Gtk as a backend, Bauhaus are custom objects. And like many things in Darktable, custom equals rotten.
In 2022, I noticed parasite redrawings and lags , when using them, leading to a frustrating user experience : the widget redrawing seemed to wait for pipeline recomputations to complete, which meant that users were not really sure their value change was recorded, which could lead them to try again, starting another cycle of expensive recomputation, and effectively freezing their computer for several very frustrating minutes of useless intermediate pipeline recomputations.
Rawspeed (the library providing the decoders for camera raw files) has deprecated support for GCC < 12. As a result, I can no longer build the AppImage on Ubuntu 20.04 (using Github runners) but I have to build it on 22.04.
It means any Linux distribution having libc older than 2.35 will not be able to start the new AppImages starting today. That should not affect most users running distributions upgraded in 2021 or more recently. Ubuntu 20.04 and other LTS/old stable distributions (Debian stable) may be affected.
If you come from Darktable, you may be used to this in the darkroom:
while Ansel offers you this:
This is no accident, and it’s time to explain why, and why this will not be extended with customization options.
I accidentally discovered that the Linux build script used a “package” build, meaning the CPU optimizations are limited to generic ones in order to produce portable binaries that can be installed on any x86-64 platform. By “using”, I mean the package build was not explicitely disabled, so it was enabled by default.
Anyway, this is now disabled by default, since the actual packages (.exe and .appimage) are not built through that script, which is primarily meant to help end-users. To get the previous behaviour back, you would need to run:
2022 was so bad in terms of junk emails and noise that I started the Virtual Secretary , a Python framework to write intelligent email filters by crossing information between several sources to guess what incoming emails are and whether they are important/urgent or not. When I’m talking about junk emails, it’s also Github notifications, pings on pixls.us (thank God I closed my account on that stupid forum), YouTube, and direct emails from people hoping to get some help in private.
It’s been roughly 3 months that I rebranded “R&Darktable” (that nobody seemed to get right), into “Ansel”, then bought the domain name and created the website from scratch with Hugo (I had never programmed in Golang before, but it’s mostly template code).
Then I spent a total 70 h on making the nightly packages builds for Windows and Linux work for continuous delivery, something that Darktable never got right (“you can build yourself, it’s not difficult”), only to see the bug tracker blow up after release (nothing better than chaining the pre-release sprint with a post-release one to reduce your life expectancy).
What happens when a gang of amateur photographers, turned into amateur developers, joined by a bunch of back-end developers who develop libraries for developers, decide to work without method nor structure on an industry software for end-users, which core competency (colorimetry and psychophysics) lies somewhere between a college degree in photography and a master’s degree in applied sciences, while promising to deliver 2 releases each year without project management ? All that, of course, in a project where the founders and the first generation of developers moved on and fled ?
