  • You still need a massive fleet of these to train those multi-billion parameter models.

    On the invocation side, if you have a cloud SaaS service like ChatGPT, hosted Anthropic, or AWS Bedrock, these could answer questions quickly. But they cost a lot to operate at scale. I have a feeling the bean-counters are going to slow down the crazy overspending.

    We’re heading into a world where edge computing is more cost and energy efficient to operate. It’s also more privacy-friendly. I’m more enthused about a running these models on our phones and in-home devices. There, the race will be for TOPS vs power savings.

    On desktop, how many people search for an emoji, then just copy paste the character into their text?

    Instead of switching to the alt keyboard, not that one, the other, no the emoji not the international one, dammit.

    Or bringing up the keyboard menu, then scrolling around, looking for the right one, searching, no, scroll, scroll scroll, etc.







  • That is actually kind of brilliant. Having to go through MFi and getting the Apple DRM chip into the manufacturing pipeline can be a real pain (and expensive).

    With this scheme, they could also run all the wired on/off and volume control actions through Bluetooth AVRCP. Even have a Mic on the wire, so if a call comes in, switch to HFP to talk/manage the call.

    Damn, that’s clever. Hats off to whoever came up with it.

    Incidentally, there’s very little Apple can do to make this stop, unless they decide to break Bluetooth and third-party accessories.




  • 12+ years on Reddit. Walked away in disgust after the API fiasco and killing Apollo. Found Voyager here and that really helped the transition.

    I miss the local subs, especially related to current events, and game day threads of local baseball team. Haven’t found a good replacement (the Athletic has them but they’re harder to navigate). On current events, unless it’s a really big national news story, not much.

    Between the loss of Reddit and Twitter, I feel like I’m getting less realtime news. But in retrospect, it didn’t really matter. I’m actually fine reading about something two days later once the outrage has died down.

    My daily usage definitely dropped, which is a good thing. I’ve been reading digital and physical books more instead of mostly a diet of audiobooks and podcasts. If there’s some idle time, I dip into a book instead of reflexively checking social media.

    FWIW, Lemmy has the same vibe as Reddit 10 years ago. I’m planning on sticking around and contributing more.




  • TPMs have been able to store encryption keys instead of having them stored on disk or embedded inside software. But TPMs were mostly connected to the main system via simple buses like I2C, SPI, or simple UART. People figured out that by sticking a cheap sniffer like the ChipWhisperer, it would be easy to read off those keys while in transit.

    Even easier would be to MITM using methods like clock glitching, so they would return fake credentials and get access to everything.

    The next generation TPMs allowed on-device private/public key creation using creative random number generation schemes and on-board crypto libraries that couldn’t be tampered with. But there was still the problem of keys going across those open busses.

    To solve this problem, you need to have attestations between the main board and TPM which means storing multiple public keys and digital signatures from both sides, either during manufacturing or on first boot.

    This way, if someone sniffs the wires, the data stream is asymmetrically encrypted. And with attestation, each side knows they are talking to only the right sender and receiver. Also, no two systems will have a common key, so even if someone de-caps a TPM2 module and gets the keys out, they can’t use it to compromise other devices.

    This is where we’re at. Manufacturing and boot processes have to be modified to make sure nothing leaks out and everything stays put.
