Free- and open-source software licenses are a clever copyright law hack. Their use has affected limited changes to societal relations to the means of software production. If you want to enact more change, software licenses alone are almost certainly not enough. Just as the Free Software Foundation and the Open Source Initiative are, you are probably going to have to get involved in politics. There are organisations which share your values.

It was great to have the opportunity again, last weekend, to see the #Sumo at the Kokugikan (#Leica #M10, #Voigtländer Apo-Lanthar 50mm F2 Aspherical). #photography

The masculine urge, when one enters one’s forties, to start smoking cigars, eat chili, wear a beige coat and drive an old Peugeot.

I feel like the Color-Skopar is the kind of lens that'll persuade you that you don't need to tighten up your exposure, framing or focusing with a rangefinder camera.

I have red-green colour blindness, and no talent for colour photography, but I'd describe the rendering of colour as being faithful and transparent as far I remember the scenes. This lens sits nicely between some of Cosina's warmer, single-coated 'classic' Voigtländer lenses, and the colder, high-contrast 'pop' of their Zeiss lenses.

I haven't noticed any radial distortion, neither barrel or pincushion, and neither the M10 or Darktable are applying any corrections. Wide-open, some minor chromatic aberration can be seen in the black script on white lanterns of the shrine in the second frame.

With such a clinical rendering, and without great light, it can be difficult to capture some mundane scenes that would benefit from a certain mood.

Focus fall-off could be a little more gradual for my taste, but the rendering of out-of-focus areas leaves absolutely no complaints.

I'm impressed with the texture detail in the wear of the paint on this road. Resolving for 24 MP is well within the capabilities of this lens. I'd love to use this on an M10 (or M11) Monochrom!

I liked the light falling on the top half of this tree. High contrast scenes are no problem for this lens, and demonstrate the dynamic range of this camera. I've reduced the black relative exposure a little.

I'm going to share some frankly boring compositions from this walk because I'd like to share (and illustrate) my first impressions of this lens. Firstly, as the name implies, it's incredibly well-corrected for chromatic aberration at almost every size of aperture.

It's kind of surreal to experience first-hand the Japanese media sensation around Mr. Mod's choices for the New York Times!

Cosina's Voigtländer-brand "COLOR-SKOPAR 35mm F2.5 P II", a Christmas present from my wife. I'm really looking forward to using this lens in this new year! The formula is almost identical to the Zeiss-brand "C Biogon T*2,8/35 ZM" also manufactured by Cosina (asymmetrical, 7 elements, 5 groups). Map Camera's staff in Shinjuku were very helpful in finding a clear filter that fit with the tight tolerances of the lens hood.

I don’t know what magic Fedora contributors perform but — despite all the complaints I read about — I’ve yet to experience a single problem with graphics (Wayland) or audio (PipeWire) on my 2017-era ThinkPad X1 Carbon. I hope these subsystems and their integration continue to improve for everyone.

I first joined Twitter in 2007, thanks to following the kinds of weblog authors who attended SXSW. I then followed Williams's Medium with interest, but was disappointed. That single paragraph is the fastest I've gone from 'don't really need that' to 'definitely don't want that'. Not everything needs to be a startup, man.
