When I am not coding I am playing the guitar in a few Polish metal bands. Last Saturday I played with one of them - AION. You can listen to AION on AM https://music.apple.com/pl/album/midian/1826590178?l=pl

Watching streaming of Back To The Beginning a farewell festival to Ozzy Osbourne. Unfortunately stream works properly only on Chrome on my MacBook Pro, so I had to plug it into a projector, luckily I can use AirPlay to send sound to my Sonos speakers. Currently watching Anthrax on stage! \m/

Besides opening tracks in Spotify, another new feature in Eter 2.6 is import&export of fav stations list to/from an XSPF file. U can import your fav stations from another app into Eter or open them in a different app on a different OS where Eter isn’t available yet :)

No electricity in entire neighbourhood until evening, so power banks and mobile router with eSIM provided rescue. However, better (but in general still rather bad) mobile coverage is in our dining room so today I have a view on our back garden.

Just got beautifully published book by MacPaw, “Innovation in Isolation. The Story of Ukrainian IT from the 1940s to the Present”. There's even a bookmark in the form of a punch card. There are photos of computers from the 1980s & photos of friends from MacPaw, Readdle (and other UA companies)

And this is my panorama of Podil with Kyiv-Mohyla Academy and a view on St Andrew’s, both taken from the top of Castle Hill (the one with old abandoned cemetery) taken day before Independence Day in 2022.
I visit Kyiv on from time to time providing stuff for my friends & humanitarian aid.

7 years ago… different times… hanging out for a beer with friends here in Lodz, Poland. And today… the one in the middle has been sentenced to 8 years in gulag (penal colony) for talking about RU aggression in Ukraine. Reading his new book just released in PL. @tomekmb.bsky.social
