For years I'd see the latest TV and movie advances and be impressed by the improvement in pictures quality. Lately I've seen some super ultra really HD film clips (I forget the technical term, it all flows into one after a while) and been astonished at how poor they look.

The extreme sharpness and clarity of the picture made everything look exactly as it really was, that is to say a group of people on a film set. The sense of the movie being a real thing collapsed.

Presumably people brought up on these newer formats don't notice it, but those making the films can't be satisfied can they?

For some time now, I’ve been gradually replacing U.S.-dominated digital services with European-developed alternatives — both on my PC and my phone. This isn’t a one-time switch, but an ongoing experiment in digital autonomy, privacy, and balance.

The screenshot shows one screen of my phone, featuring European apps and platforms that I actively use or am currently testing. These include alternatives to browsers, email, messaging, navigation, video, search, and more.

This journey was inspired in part by the European Alternatives directory — a fantastic, regularly updated list of digital tools created and hosted in Europe. The project was started by Constantin Graf, an Austrian developer who maintains the initiative.

Here’s a selection of European apps I’m actively using or currently testing — some of which appear in the screenshot:

  • Vivaldi: A privacy-focused Norwegian browser
  • Mastodon: Federated microblogging platform. I’m also testing Rodent, a Mastodon client that feels more complete in terms of UX/UI.
  • Pixelfed: Federated image-sharing platform, focused on privacy and decentralization.
  • Qwant: A French search engine
  • Threema: Swiss secure messenger
  • Proton Mail: Swiss encrypted email
  • PeerTube: Decentralized video platform
  • pCloud: European cloud storage
  • Mullvad VPN: Swedish privacy-first VPN
  • Spotify: Swedish-based streaming service — although some question its alignment with European digital sovereignty
  • HERE WeGo: Navigation app developed in Germany. I’m also testing Lokjo, a promising open-source alternative using OpenStreetMap.
  • Le Chat: Chatbot interface for Mistral AI’s French language models
  • European Alternatives: Mobile version of the directory itself

This isn’t about cutting all ties with US services overnight. It’s about creating space — to support platforms that reflect European values like transparency, sustainability, and decentralization.

If you’re curious to explore alternatives, the European Alternatives directory is a great place to start.

I’ve been using Tapestry and Reeder to get one consolidated timeline of everything I follow, but I’ve noticed that it feels a bit like window shopping. Looking at people’s posts, but never interacting with them. Then the latest TestFlight build of Tapestry goes and solves that problem. Combined with the crosstalk feature it’s great to see how the @IconfactoryThe Iconfactory continue to nail it.

샘 알트먼 "챗GPT에 '감사합니다' 할 때마다 수천만 달러 나간다"

AI리포터 · [디지털투데이 AI리포터] 샘 알트먼 오픈AI 최고경영자(CEO)는 챗GPT에 '부탁합니다' 또는 '감사합니다'라고 말하는 것만으로도 회사에 수천만 달러의 비용이 든다고 밝혔다. 17일(현지시간) IT매체 테크레이더에 따르면 알트먼은 '오픈AI가 사용자의 공손한 표현 때문에 전기 요금으로 얼마나 손해를 봤을까?'라는 한 엑스(트위터) 사용자의 게시물에 "수천만 달러가 쓰였다"고 답했다. 지난 2월 영국의 미디어 기업 퓨처(Future plc)는 1000명 이상을 대상으로 AI 에티켓에 대한 설문조사를 실시했다. 그 결과, 약 70%

The amazing inductively coupled PCB memory uses NO electronic or mechanical components per bit. The data is literally stored in the PCB traces. There is one diode per 64-bit word (512 doliodes total), 48 line drivers, and 64 sense amplifiers
This technology was never used again, as bipolar PROM semiconductor memory chips appeared in 1969.

The HP 9100 calculator uses core memory to store a user program and data, but the internal read-only control store (microcode) is stored in a novel and patented inductively coupled printed circuit board memory (512 words of 64 bits), and a core rope (or wire braid) memory (64 words of 29 bits).

people have always existed. But in a world obsessed with sex, their existence gets continually erased — sometimes through silence, sometimes through mockery, and sometimes through loud and proud ignorance.

Cait the Proud Trans Woman @oldladyplays@wargamers.social

A thought for trans allies in this time:

You often ask us what you can do to help. Well, here's something you can do. Wear trans badges, buttons, pins, scarves, whatever you've got. Explicitly. I wanna see that blue and pink EVERYWHERE.

Because the more of you cis folk do that, the safer we will be in crowds and such. It will mean that wearing a badge of support for trans people doesn't necessarily out that person as trans.

"But wait," you're thinking maybe, "if I do that, people might think *I* am trans!"

Well, why is that a problem for you? Would you be offended by someone thinking you might be trans? Would you be scared? Welcome to our world.

This is your time, cis people. You were all ready to call yourselves allies when it didn't matter more than changing your PFP background. Now the rubber meets the road. We need you. We need your help to normalise our existence to other cis people. It could save lives.

If someone accuses you of being trans (imagine being *accused* of existing while trans?), don't deny it. Ask why it matters to them. Keep calm.

同じわけではにけど言い方が色々あるな
be former ○○（現在、以前先生だったのであればis/are former）
be ex-○○ (同様）
上二つは主に現在系で使われるだろうけど
これに加えて、ニュアンスは違うがbe retiredもあるか
一応全部EN-JPで使ったことあるな

2020 wurde ich wegen dieses Cartoons weil er gegen die Konzernrichtlinien verstößt nach kurzem hin- und her für Facebook und alle Metaprodukten auf Lebenszeit gesperrt. Wo die Richtlinien Nazis schützen, kann kein Platz für mich sein. Seither poste ich diesen Cartoon jährlich an Führers Geburtstag.

Eine Frau geht wütend schimpfend an einem Naziaufmarsch vorbei. sie ruft den Nazis zu: Ihr Gottverdammten Freizeitnazis!!! Jedes Jahr Führers Geburtstag feiern und jedes Jahr aufs neue vergessen, sich zehn Tage später eine Kugel in den Kopf zu jagen! Schande!
