  • Apple has the target disk mode, but doesn’t the laptop need to be shut down for it to work?

    Modern Macs can’t do Target Disk Mode. If you had the right cables (thunderbolt or firewire) it was really fast, just as quick as a high end internal PCIe SSD.

    And yes, you did need to reboot - because the other computer had full arbitrary read/write access to the raw sectors on the drive with no safety checks or security. If you did that while the computer was running normally, you’d corrupt the data on the disk as soon as they both tried to do a write operation at the same time — and also TDM needed to be used with caution - the other computer could easily install a rootkit or steal all your saved passwords.

    It’s been replaced with “Mac Sharing Mode” which operates while the Mac is running normally, does have all the necessary algorithms in place to avoid corrupting the disk, full security to authenticate each read/write operation and block attempts to mess with system files, and therefore is orders of magnitude slower than TDM.


  • Solar, wind, hydro can do it, but the amount of CO2 produced by manufacturing the generators is still massive

    That’s FUD.

    Sure - the concrete in a large hydro dam requires a staggering amount of electricity to produce (because the chemical reaction to produce cement needs insane amounts of heat), but there’s no reason any CO2 needs to be emitted. You can absolutely use zero emission power to high temperatures needed to produce cement.

    And not all hydro needs a massive concrete wall. There’s a hydro station near my city that doesn’t have a dam at all - it’s just a series of pipes that run from the top of a mountain to the bottom of a mountain. There’s a permanent medium sized river that never stops flowing that comes down off the mountain - with an elevation change of several hundred metres. It provides more power than the entire city’s consumption and does so while only diverting a tiny percentage of the river’s water. As the city grows, the power plant can easily be upgraded to divert more of the water though pipes instead of flowing uselessly down towards the sea.

    Covid and Russia’s war created massive fluctuations recently but if you look through that noise global CO2 emissions are pretty much flat and have been for a few years now. They are almost certainly going to trend downwards going forward (a lot of countries already are seeing downward movement).

    The simple reality is fossil fuels are now too expensive to be competitive. Why would anyone power an AI (or mine crypto) with coal power that costs $4,074/kW when you could use Solar at $1,300/kW (during the day. At night it’s more like $1,700 to $2,000 with the best storage options, such as batteries or pumped storage). Or wind at around $1,700.

    Nuclear is $8,000/kW unless you live in Russia, where safety is largely ignored.

    Hydro can be cheap if you happen to be near an ideal river - but for most locations it’s not competitive with Solar/Wind. So hydro is safe as a long term power generation method into the future, but it’s never going to be the dominant form of power unless (like my city) you happen to have ideal geology.


  • Unless you pay for expensive tags (like $20 per tag) or use really short range scanners (e.g. a hotel key), RFID tags don’t work reliably enough.

    Antitheft RFID tags for example won’t catch every single thief who walks out the door with a product. But if a thief comes back again and again stealing something… eventually one of them will work.

    But even unreliable tags are a bit expensive, which is why they are only used on high margin and frequently stolen products (like clothing).

    All the self serve stores in my country just use barcodes. They are dirt cheap and work reliably at longer range than a cheap RFID tag. Those stores use AI to flag potential thieves but never for purchases (for example recently I wasn’t allowed to pay for my groceries until a staff member checked my backpack, which the AI had flagged as suspicious).


  • I’m betting the owners of the NYT would LOVE to have an AI that would simply re-phrase “news” (ahem) “borrowed” from other sources

    No way. NYT depends on their ability to produce high quality exclusive content that you can’t access anywhere else.

    In your hypothetical future, NYT’s content would be mediocre and no better than a million other news services. There’s no profit in that future.

    Where will they get their info from with no one to scrape?

    It’s not like there’s a shortage of human generated content. And the content that has already been generated isn’t going anywhere. It will be available effectively forever.

    just “standing on the shoulders of giants”.

    So? If you ask an LLM a question, you often get a very useful response. That’s ultimately all that matters.

    I disagree. The real news is the free model will now search the internet for up to date answers, and for calculations it will write and execute a python script, then show you the result.

    Paid users of ChatGPT have had those features for months, and they were a massive step forward in terms of how often the AI provides accurate answers.

    you can run locally some small models

    Emphasis on “small” models. The large ones need over a terabyte of RAM and it has to be high bandwidth (DDR is not fast enough).

    And for most tasks, smaller models hallucinate way too often. Even the largest models are only just barely good enough.






  • Google doesn’t own most of their map data - they license it off other companies that have spent decades and billions of dollars collecting map data from all around the world.

    So even if Google gives a project a “special deal” it’s still not going to be free. Open Street Map, on the other hand, is totally free. And in some ways it’s better than Google Maps — because it has millions of people contributing to the map. No commercial mapping company can come close to the level of detail OSM has. Compare these two screenshots — the Google map has so much less detail it’s not even recognisable as the same place. Roads and major features are missing or drawn in the wrong place.





  • They took the open source WebKit to develop Chrome and Chromium.

    How did that turn out?

    Perfectly? Web browsers are way better now than they ever have been.

    Google wants to own images. Doesn’t matter if they made the licensing whatever. They make webp. They have a personal vested interest in control.

    WebP is a little better than PNG/JPEG and way better than GIF. That’s all that really matters.

    You trust Google???

    Hell no. I reluctantly watch a bit of content that’s exclusively available on YouTube. Don’t use anything else of theirs and I’d drop YouTube in a heartbeat if I could find that content elsewhere.
