I remember buying a BOOK (as in printed on paper) directory of the internet in my university book store (was that published by Netscape? Anybody old enough to remember?)

I feel the same way about AI that I did about crypto when it started becoming a thing:

• All of the moral practices that make it possible are fucked beyond repair.

• It’s spawning some of the worst companies, and enriching some of the worst billionaires in the world.

• While there are some genuinely useful, practical applications for it, there are so few of them, and they have had so little positive impact so far, that it doesn’t even seem like it’s going to be worth it anytime soon.

True, but all the AI models in cancer, climate, ... research are fundamentally different from the ChatGPT type AI that is hyped at the moment. And the tech bros are less interested in those useful forms it seems.

I'd argue that it is part of the unethical practice, though, to conflate the two and attempt to disarm any criticism of the ChatGPT type AI pointing at AI use in cancer and medical research.

And it it indeed a shame if those uses get a bad reputation as a fallout from all the everyday AI hype.

Based on my experience talking to women who travel alone, there definitely is reason. Not a single one of them did not have stories to tell about sexual harassment or worse.

The problem we, as men, have, is that these women don't usually talk to us* about it**. So our perception must be biased.

BTW, most of these stories I heard won't show up on any statistic.

*not sure why they talked to me about it. Must be because I am more like a bear.

**maybe because they don't care to be mansplained or victim-blamed.

    🆕 blog! “The limits of General Purpose Computation”

    Should my bank be able to block me from using their Android app, just because my phone is rooted? I'm reluctantly coming to the conclusion that... yeah, it's fair that they get to decide their own risk tolerance. Sage of the Internet, and general Sooth Sayer, Cory Doctorow once gave an impassioned…

    @Edent, I guess you know all this, but think it's interesting for others in the discussion.

    There are two levels here:

    1. your device manufacturer does not allow installation of alternative OSs in a safe manner. Others do allow relocking the bootloader and don't need root access.

    2. the banking app does not allow unlocked bootloader or rooted devices.

    I'd argue that (2) is reasonable, and (1) is the problem that restricts our freedom to use the device as we want. Locking the bootloader is, like Secure Boot on PCs, not a problem per se, only if the only authorisation of the boot chain is in the hands of the manufacturer.

    There are not many manufacturers that allow relocking bootloaders, though. Which is why most alternative Android devices run insecurely (I would not want to run such a device, and definitely not want my patents in law running one).

    Ironically, one of the best choices, if one wants to run an alternative (de-Googled) OS, are Google's own Pixel phones.

    I run a Fairphone 5, which is pretty open as well (I run IodeOS) and all banking apps work.

    Is there any digital data storage hardware and associated encoding that has an intended archival life of at least 1000 years without electricity?

    I know it's an old question, but given that paper or palm leaf manuscripts last that long, is there any standard out there which would support civilizational timescales?

    No bonus points for guessing why I'm wondering about this.

    Really good question. Wondered about that myself recently. What was Asimov's solution in Foundation?

    Whilst we all focus on the catastrophe that is ever-increasing atmospheric CO2, methane levels are shooting up - and methane has a much higher warming potential than CO2.

    For some definition of "dealing with it", they are. My cynical self thinks they are intentionally kicking the can down the road, until geo-engineering solutions will become inevitable and accepted in by the general public.

    If it's only images, then epub is not the right format. But then, if it's only images, and the images contain text then that'll pose accessibility issues.

    There are some comic formats, that may be suited for image only.

    Pondering some form of e-Ink and am looking for recommendations. Ideal featureset:

    Screen: ~7" - don't like holding a 10" iPad, and an expired 6" ereader seems a fraction small.
    PPI: >~300
    Wifi
    Ability to sync to/from CalibreWeb

    I'd rather not pay Amazon for their products so that probably excludes the Kindles unless they are outstandingly worth it. Thoughts?

    Hälfte der weltweit verkauften Neuwagen sind SUVs

    20% des globalen CO₂-Anstiegs gehen auf SUVs zurück.

    Wären SUVs ein Land, wären sie der fünftgrößte CO₂-Emittent der Welt, noch vor Japan und Deutschland.

    20% der neuen SUVs sind EVs oder Hybrid.
    Große Autos brauchen aber größere Akkus, mehr Mineralien und mehr Strom.

    Einfach ein entsprechend niedrigeres Tempolimit für Autos, die breiter als, z.B., 1,9m sind. Sollte die Nachfrage gewaltig reduzieren.

    Alcohol consumption in the EU has declined by 0.5 litres per person between 2010 and 2020. However, there are several countries where consumption increased, Euronews reports:

    Statistisches Bundesamt: Wirtschaftsleistung im Sommer geschrumpft

    Besonders die Zurückhaltung beim Konsum belastete die deutsche Wirtschaft im Sommerquartal. Das Bruttoinlandsprodukt verringerte sich laut Statistischem Bundesamt von Juli bis September um 0,1 Prozent. Die Ökonomen hoffen auf 2024.

    I decided I need a new hobby and a musical challenge.

    I never played finger-style guitar, so learning this 13-string instrument is quite a daunting prospect.

    Looking forward to my first lesson next week with @jacobheringman at the in Saltaire.
