I’ve got a lot of my own music piling up on my Mac—songs that don’t fit metal bands I play in, as they’re mostly rock or rock-metal. I don’t want to reshape them. Sacriversum and AION are my priority, but I don’t want these tracks to stay unheard forever

We just got our copy of "Security Guide" in case of there is even more „peace” in the world. There are advises how to secure windows, doors, how to prepare for being cut of of supplies, food and electricity, how to protect ourselves in case of air raid.

No one talked so much about peace like Mussolini, Hitler, Putin and… Trump.

Light Junkie, une petite app pour suivre les jours qui rallongent L’hiver vous déprime et vous attendez le retour du printemps avec impatience ? Le développeur Krystian Kozerawski a pensé à vous avec Light Junkie, sa nouvelle app qui permet de facilement suivre les minutes de soleil gagnées chaque jour. Il s’agit d’un de ses projets personnel, assez simple mais qui devrait en intéresser plus d’un en cette période où les journées sont courtes. L’interface principale. Image iGeneration L’app donne des informations sur les heures actuelles de lever et de coucher du soleil. On y trouve d’autres données comme la durée du jour par rapport au plus court de l'année (le solstice d'hiver), ainsi que par rapport à la veille. Des prévisions sont également proposées. Il est possible de recevoir des notifications pour le solstice d’hiver ou d’été, mais aussi pour les équinoxes (quand le jour et la nuit font la même durée). On peut sinon en configurer pour certains paliers de soleil gagné ou pour être alerté des jours polaires (durant lequel le soleil ne se couche pas). L’application propose également différents widgets pour garder un œil sur l’évolution des jours. L’app est entièrement gratuite, mais un achat in-app de 1,99 € est demandé pour suivre plus d’une ville à la fois. Light Junkie est optimisée pour iPad et disponible sur les Mac Apple Silicon. On regrettera juste qu’elle ne soit pas traduite en français. Plusieurs widgets sont disponibles. Image iGeneration Krystian Kozerawski a développé plusieurs apps que nous avons relayées, comme le lecteur de PDF avec un mode nuit Negative ou l’application de radios Eter. D’autres apps similaires à Light Junkie existent déjà comme Skylight pour anticiper l'heure dorée ou encore Lumy, mais cette dernière nécessite un paiement de 9,99 €.

Warning: political rant. The more I watch "the king of the best country in the world" the biggest impression I have that I am watching Scary Move 3 or 4, or Naked Gun series. But the king is not Leslie Nielsen and it is scary movie for real. Especially when you watch it here, in Poland.

A few photos taken during rehearsal of my death metal band SACRIVERSUM with my son Olaf on a guitar (he is not just a rytm guitarist or second guitar. He takes over some of the solos from me too). We have already booked 11 shows until end of May. Three gigs in January.

Trombalsky is the name of an elephant from a poem by Julian Tuwim, one of my favorite Polish poets. Of Jewish origin, he was known for children’s poems as well as poems and sharp political epigrams for adults, among them excellent political satires. https://en.wikipedia.org/wiki/Julian_Tuwim

Over the holidays I also spent some time on Trombalsky, my Mastodon/Bluesky client for iOS and macOS, adding many features incl. search. There’s still plenty to do, but since it’s already my main client and it's a side project, progress is quite slow.

Two cats at the opposite sides of terrace window doors

Close encounters of the third kind… we have two black cats. The black & white one roams in the neighborhood while being rather domestic (I guess it is one of our neighbors).

During this Christmas I did my small side project - Light Junkie for iOS and macOS. This little app shows daylight gains vs winter solstice and yesterday. It also shows sunrise and sunset times as well as dawn and dusk times. Currently waiting for review in App Store. And yes… I am a light junkie

@mackuba.eu not yet, at least not with me :) Maybe there is a bar somewhere in my house, where all iPhones of my family come and drink together. This is the question of same kind as Philip K. Dick's "Do Andoids Dream of Electric Sheep" :)
