Satellite launches have increased exponentially since 2020, and now space debris is increasing at a similar unbelievable rate, making the hypothetical Keppler Effect (also Kepler Syndrome) a very real possibility in the near future. As this material eventually deorbits and rains down into the planet, it vaporizes into metallic oxides like Aluminum Oxide (Al2O3) and toxic compounds, which poison the air and also degrade Ozone (O3), the delicate oxygen layer in the stratosphere which provides life from harmful UV radiation. Geophysicist Stefan Burns reports on the situation…

  • This is about AI and learning.

    I have an interesting observation: I had the last few years the opportunity to work with older legacy code bases. And I came to the conclusion, that understanding them for me requires systematic learning. Pretty much like learning a language.

    Say you have 70,000 lines of code with about 8000 to 10000 identifiers. Also a number of implicit concepts. Invariants and so on.

    To work with the code, you need some basic understanding. To understand, you need an idea what these identifiers mean. Or their important subset.

    Now, remember that the human brain can only keep six or seven things in short-term memory. To store more, the meaning of all these identifiers, concepts, invariants etc… … - needs to go into long-term memory.

    Which means repeating and memorizing around 10,000 things.

    That is similar to learning a foreign language up to a pretty good level.

    So. you need that learning process to work with legacy code.

    If AI use inhibits this - this means trouble.

  • Guix provides security patches. You can also define your own derived packages and patch them. Or fork the distro and build it with a different kernel and base packages, like the nonguix fork does. Or add an own patched OpenSSL library.

    But what such approaches come down to in practice is that maintaining a forked distribution is a lot of work. For most people, the sane approach is to build on an existing distro.

    It is not an easy problem. For example, the buildroot distro which is popular for embedded devices, AFAIK has only one release every six months.

  • The alternative would be a mid-range phone with SailfishOS on it. I have one, a Sony Xperia III which I chosed for the small size. I like it. BTW I had nearly every Linux phone by Nokia and Jolla since the N900.

    But if you still want something that is more like a pocket computer and less like a distracting phone, you could look for handheld PCs / ultraportables, and put Linux on one. These can run Threema Web, and Waydroid if you still want apps. (I have a Gemini PDA, and I like it, but be careful - this is NOT a phone - but fine for answering mail).

  • By the way, secure open trust systems are hard. Around 2000, there was a FOSS web site called kuro5hin.org, a slashdot-sryle discussion board, which experimented with trust networks. As far as I remember, they did not find a good solution.

    Wikipedia or stack overflow has the same issues.

    I think a kind of real-life-based(!), signature-based web of trust like the GnuPG web of trust (but ideally with more user-friendly software…) could be part of the solution

The manufacturer explicitly positions the device as a response to constant availability and what it considers problematic mechanisms of modern smartphone platforms. In conversation with heise, Commodore CEO Peri Fractic describes the Callback 8020 as a “not stupid dumbphone” for people who want to spend less time scrolling and more time in the real world. It is envisioned as a secondary device for staying reachable without being constantly exposed to the temptations of a smartphone with its notifications, apps, and games. The decision was influenced by his young daughter and his own behavior: “I was addicted to my smartphone,” says Prei Fractic.

Fantastic. We need more people like that.
