  • 2- positive supply-chain validation. Not important for the majority of people, but for those who require a little more security, they can be a little more sure that their device isn’t compromised from illegitimate parts. I imagine this to be a fringe benefit for executives and the like

    Anecdotally, many years ago I had a Mac laptop that was fairly new but I ran it as what amounted to a portable desktop. It was plugged in 99% of the time. A few months after I got it I had an issue with one of the fans. Instead of taking it to the Apple Store that was 90 miles away (I was living and working in a small town then), I took it to the local computer repair… and they fixed it it.

    Afterwards, while I didn’t use batteries much, it seemed off.

    Another two years and I had moved to a larger city and took my laptop into the local Apple Store for them to replace a fan that was not operating strongly enough. The repair tech commented that I had a sub par third party and while it should be replaced as its battery health was very low, it wouldn’t be covered under warranty because it clearly wasn’t an OEM Apple part.

    I strongly suspect that the repair shop had swapped my new battery out for an old one and hoped I wouldn’t notice because I didn’t use it in that capacity. I can’t prove anything and the shop had gone out of business.

    This is anecdotal and batteries for laptops don’t get pairing the same way phones do… but this sort of thing happens.



  • You don’t need iodine, this isn’t going to give you radiation sickness, but it is a little surprising.

    From a WaPo article:

    France’s digital minister said the iPhone 12’s radiation levels are still much lower than those that scientific studies say could harm users, and that a software update could solve the compliance issue. The ANFR itself acknowledges that its tests don’t reflect typical phone use.

    Which links to:

    The @anfr found that the iPhone 12 was emitting a level of waves slightly higher than the authorized threshold.
    This level is more than 10 times lower than the level at which there could be a health risk.
    But the rule is the rule: Apple must comply.

    The wave levels that smartphones emit can vary during a software update. It is undoubtedly because of an update after its release that the iPhone 12 exceeded the authorized threshold. And it’s a simple update that will bring it back into compliance.

    The classic conditions of use: the real DAS

    Laboratory measurements do not reflect what happens during the usual use of the device. Indeed:

    • for voice communication, the phone statistically emits only about 50% of the time, the phone does not emit when listening; in addition, the average duration of a communication is less than 3 minutes;
    • for data-oriented use (internet or video), the durations of use are certainly longer; but the phone, which generally receives more information (videos, emails…) than it sends, rarely emits more than 10% of the time during the session;
    • the value of the DAS displayed in the points of sale corresponds to a precise frequency (e.g. 800 MHz) and technology (e.g. 4G) for which the maximum has been detected; but, in reality, the phone does not work permanently under these conditions: it often changes frequency or technology;
    • Finally, for all uses, the phone rarely emits at its maximum power, due to constant interactions with the network to best adapt to its conditions.

    The real SAR therefore does not often coincide with the maximum SAR.

    As the DAS is proportional to the power emitted by the telephone, it is possible to evaluate the actual DAS by measuring the power put into play by the terminal. This can be evaluated thanks to professional software installed on consumer phones







  • ChatGPT works off of a fixed size possible maximum prompt. This was originally about 4000 tokens. A token is about 4 characters or one short word, but its not quite that… https://platform.openai.com/tokenizer

    “Tell me a story about a wizard” is 7 tokens. And so ChatGPT generates some text to tell you a story. That story is say, 1000 tokens long. You then ask it to “Tell me more of the story, and make sure you include a dinosaur.” (15 tokens). And you get another 1000 tokens. And repeat this twice more. At this point, the length of the entire chat history is about 4000 tokens.

    ChatGPT then internally asks itself to summarize the entire 4000 token history into 500 tokens. Some of the simpler models can do this quite quickly - though they are imperfect. The thing is at point you’ve got 500 tokens which are a summarization of the 4 acts and of the story and the prompts that were used to generate it - but that’s lossy.

    As you continue the conversation more and more, the summarizations become more and more lossy and the chat session will “forget” things.





  • Another promise was that we’d be able to basically have access to every tv show or film, and that evaporated very quickly when all the studios decided they wanted to gatekeep everything so they could charge even more for it, and then now we have them disappearing so many things that have been out there just because they don’t want to pay royalties to anyone involved.

    That is one part of it. The studios believed that if they did the distribution they’d be able to have a larger slice of the pie. This isn’t working as well as they thought it would in many cases (Disney is likely the exception if there is one with a very large historical catalog and several profitable franchisees) but didn’t realize the corresponding infrastructure and (customer) support costs that would incur reducing the amount that they make.

    Furthermore, the residuals (things that are currently at stake in striking) are based on “having it available” even if no one is watching it. This means that studios (and Netflix and Amazon) are strongly incentivized to remove shows that aren’t getting watched sufficiently for the draw of having them there because they’re paying residuals no matter if its being watched or not.

    Having a streaming catalog of 10,000 shows (Netflix has about 13,000 world wide by some accounts with about 5000 available in the US) would mean they’re paying small amounts to everyone even if they’re not getting watched. If the company (e.g. studio) isn’t set up around the infrastructure and support needed for streaming, this can easily mean that those small amounts can become more than the amount that the company is making off of streaming.

    Ever notice how Amazon Prime Video rotates in lots of B movies that are available for a few weeks and then disappear again? This is to get people to watch them but minimize paying residuals for having a bunch of movies and TV series that no one watches otherwise.

    With the combination of race to the cheapest for pricing (and sharing of accounts), and infrastructure / operational costs it is quite possible to be in the situation where studios are losing money on hosting shows and at the same time paying actors and writers far less than is fair… and the easiest solution that studios have to resolve this is to aggressively pull shows.
