  • Apple is reportedly not investing in OpenAI

    jdw said:
    As I've mentioned under other articles in the past, my experience with ChatGPT4o isn't that great.  I want like to use it to check multiple online sources quickly, in the hope it can Google faster than I can on my own.  And it is fast.  But the problem is, it lies a lot.  So I always ask it for sources.  Then it gives me stupid links that when clicked on, open nothing.  So I have to then as it for plain text URLs.  It complies, but none of them ever work.  EVER!  They lead to the expected domain, but they always result a 404 file not found.  ALWAYS!  I then complain to ChatGPT saying it needs to read the articles it links for me to ensure the article truly exists and exists at the plain text URL it will give to me.  It apologizes and seemingly complies, but it continues to give me more bogus URLs.  I have repeated that cycle multiple times in a row, until my free sessions with GPT4o expires.  It never learns from its mistakes.  It never gets it right.  I've been using it for months, and it hasn't improved at all in that regard.  So I mostly find it useless.  And this experience remains valid even if some GPT lover comes along a raves about how well it summarizes text.  Fine and well, but it still lies and gives bogus URLs to its source info.    
    I find it gives very good answers for technical questions that have a correct answer that would be difficult to find online but it does make mistakes.

    Duckduckgo has it integrated now:


    It offers GPT-4o, Claude 3, Llama 3 and Mistral. Try the other models to see how they compare.

    Very subjective questions like political, social, moral questions will have subjective answers depending on the training data.

    Getting access to high quality training data is going to be the biggest challenge for AI models. It needs a trust/authority model to weight the answers. Medical answers should give more weight to peer-reviewed medical texts over random Reddit/Youtube commenters.

    It's important to remember that the models are not continually trained, they are snapshots. You can ask a model directly when it was trained. GPT-4o answers up to October 2021 so it doesn't know about the past 3 years. Some of its online sources will have expired since it was trained. The new upcoming models have been trained after 2021 with more computer power:


    They now have metrics for how the AI compares to human baseline performance, future models will keep trying to outperform these baselines in different areas:


    It's easier for AI to excel at deterministic problems. Non-deterministic problems need huge amounts of high quality data.

    The processing power they are using on the servers is increasing significantly every year and the models will improve significantly when they are updated.



    Some people won't be impressed with AI models until they reach AGI level, there are people projecting this before 2030.

  • If you're having problems with USB on macOS Sequoia, you're not alone

    I have had an issue for quite some time, possibly since Ventura, where the dialog asking me to allow the USB device to connect disappearing within a fraction of a second. I miss the dialog altogether. My workaround has been to unplug the device and plug it in again, repeatedly in necessary, until I can okay it. From then on I don’t have a problem with the device.
    The confirm dialog disappearing so fast is really badly designed, I don't know how that got past testing. There's a preference in System Settings to avoid manual approval of new devices:

    Another fix that can sometimes work for drives not mounting is force quitting the diskarbitrationd process and plugging the drive in again.

  • Apple may cut future Apple Vision Pro cost with far cheaper displays

    Any idea how many units have been sold?
    There's some information from the wearables revenue:

    https://s2.q4cdn.com/470004039/files/doc_earnings/2024/q3/filing/_10-Q-Q3-2024-As-Filed.pdf

    Wearables, home and accessories in 9 months ending June 29th 2024 = $27.9b. The same period the year before was $30.5b. The Apple Watch makes up around half the total. iPhone/iPad accessories (AirPods, cases, chargers, keyboards) make a significant amount, mainly AirPods, which are estimated to be close to half the amount too. AirPods + Watch are easily 80-90% of the total wearables category, possibly more.

    1m Vision Pro units would be over $3.5b. Given that the total fell nearly $3b, it's not likely Apple Vision Pro made over $1b, < 300k sales in 9 months.

    Not too surprising considering it had a US-only launch initially and the fact that $500 VR headsets like Meta Quest only sell 5-10m units per year.

    A sub-$2000 headset would sell millions of units.

  • Upcoming M4-based Mac mini rumored to replace USB-A with more USB-C ports

    nor will a decision by Apple to drop all USB-A ports on the Mac Mini dictate what the Windoze PC world will do.
    Apple is pretty influential these days, especially with mobile and this isn't a decision that's going against the grain. PC manufacturers would love to have the mobility Apple has with the latest standards. They don't have that luxury because their competitors adding more ports count as competitive features and there's little brand loyalty among low quality brands.

    PCs are trying to make thinner laptops now and they are only fitting the USB-A ports at the thickest parts of the laptops. This one has 2x USB-C/Thunderbolt and 1x USB-A:

    https://www.amazon.com/ASUS-Zenbook-Touchscreen-i7-13700H-Thunderbolts/dp/B0CDD8BFH1/

    Mobiles are all USB-C and come with USB-C cables and chargers. That hugely influences the ports that are added to computers.

    By the way, I just bought the single best 1TB Thumbdrive SSD today on Amazon only 1 hour ago, and guess what?  The connector only comes in USB-A.  Check it out too, because it beats any other thumb drive out there.  Pretty incredible.  And yeah, I'll need to use a STUPID DONGLE with it on my 16" M1 Max MBP
    There's also the Kingston USB-C drive, which will give mostly the same real-world speed:

    https://www.amazon.com/Kingston-DataTraveler-256GB-USB-C-Performance/dp/B09DVPH8NQ

    The external SSDs are almost as compact as thumb drives now, some are faster and offer more capacity:

    https://www.amazon.com/SanDisk-1TB-Extreme-Portable-SDSSDE61-1T00-G25/dp/B08GTYFC37/

    This is 100mm x 52mm x 9mm
    vs
    92mm x 30mm x 14mm for the thumb drive

    This one is around the same size and 3x faster because of USB-C/Thunderbolt3:

    https://www.amazon.com/SanDisk-Professional-1TB-PRO-G40-SDPS31H-001T-GBCND/dp/B0BGYMJBQF/

    Once you own a USB-C-only computer, you will gradually move all the peripherals to USB-C connectors/cables and the exceptions will eventually drop to one or two products. Changing standards over the years have always been painful (firewire, displayport, mini-displayport, ADC, DVI-I, DVI-D etc) but this is one of the least painful because it's a compatible port.

    USB-A is still ubiquitous (unlike USB-C) and Apple going to all USB-C on a new Mac Mini won't change that fact in the least.  For better or for worse, USB-A is here to stay, and I suspect it will continue to be used 10 or 15 years hence.
    Keeping support for it on computers is what keeps manufacturers making the products with USB-A. This has been played out a number of times with different ports over the years and it's why VGA ports were on PCs long after they were useful.

    USB-C is at a point where most products can be supported by changing cables. Logitech keeps shipping USB-A receivers with their mice and they sell an adaptor instead of a native USB-C version but their mice work fine over Bluetooth without the adaptor.

    https://www.amazon.com/Logitech-USB-C-to-USB-A-Adaptor/dp/B09JL9RQN5/

    All computer manufacturers should start dropping USB-A so there's not a repeat of VGA. USB-C is faster, more compact, easier to plug in (works upside down), can charge an entire laptop supporting 100W of power and more. It's better in every way than USB-A.

    For the rare products that have wired USB-A cables, the adaptors like the Logitech one above can be left attached to the cable.
