sounds··on Google “We have no moat, and neither does OpenAI”
Fortunately, what I said was that a single company becomes the sole source for the ML in education; not the same thing and thus I have no conflict with your statement.
sounds··on Google “We have no moat, and neither does OpenAI”
Repeating myself from https://news.ycombinator.com/item?id=35164971 :

> OpenAI can't build a moat because OpenAI isn't a new vertical, or even a complete product.

> Right now the magical demo is being paraded around, exploiting the same "worse is better" that toppled previous ivory towers of computing. It's helpful while the real product development happens elsewhere, since it keeps investors hyped about something.

> The new verticals seem smaller than all of AI/ML. One company dominating ML is about as likely as a single source owning the living room or the smartphones or the web. That's a platitude for companies to woo their shareholders and for regulators to point at while doing their job. ML dominating the living room or smartphones or the web or education or professional work is equally unrealistic.

sounds··on Geoffrey Hinton leaves Google and warns of danger ahead
Can you clear up specifically what about the second video you think is difficult to understand?

I saw an example of a conversation where the Snapchat 'My AI' was tricked into grooming a child, with the likely outcome being heavy regulation if left alone.

sounds··on Google announces Q1 2023 earnings [pdf]
Ad spend globally may be down; can a comparison be made to competitors' ad revenue to come up with a baseline there?

Youtube was a large contributor to growth in 2021-2022, and that engine appears to have slowed. (Not just the "Youtube ads" line that is separated out.)

Most likely the market is reacting to these results not being any worse. Cloud gains were already priced into the stock, in my opinion.

sounds··on Smokeless_UMAF: Access AMD hidden BIOS settings
Just in case it needs to be said, the reason S3 sleep is disappearing is pressure from Microsoft to switch to "Modern Standby" which is more of a "connected, always-on" state.

sounds··on In 1981, Intel released the iAPX 432
Some of the GPU shader languages restrict the code so that it's "almost" impossible to have a segmentation fault.

I know it's not what you are looking for since it's not making nearly enough bounds checks. I thought I'd drop a mention since it's widely available.

sounds··on Intel won't back down on chip ID feature (1999)
Disclaimer: I am not a lawyer.

The term "CPS" narrows down what state you're in.

Be sure to retain an attorney, and meet with CPS up front (ideally before the child is born, but as soon as reasonably possible).

CPS will most likely not enforce on child neglect if the sense is that you are both (1) respectful (2) lawyered up (3) proactive. It is because they are very unlikely to prevail in court in these situations.

sounds··on AMD and Jedec Are Collaborating on DDR5 MRDIMMs at 17,600 MT/S
NVME's peak advertised speed is only achievable when you're hitting the NVME's DRAM cache.

The PCIe link isn't going to be competitive with the DDR5 link, since both are measuring DRAM access speeds in this case.

sounds··on The day Windows died
Just finished setting up a new machine for an older relative that boots instantly into linux, starts qemu with a copy-on-write version of Windows 7.

It doesn't need updates because they don't access the internet, good luck virus writers when it gets nuked from outside the VM every time it reboots!

sounds··on Apple halted M2 chip production in January amid 'plummeting' Mac sales
Apple's products enjoy a halo effect, driving up demand. But their chips don't because the new M2 competes against their own existing products.

I expect Apple will make some more concessions to repairability in order to maximize their ROI after buying out TSMC's leading edge node.

sounds··on How and when the chip shortage will end
tl;dr:

    ... the most problematic shortages will begin to ease in the third or
    fourth quarter of 2021, though it could take much of 2022 for the
    resulting chips to work their way through the supply chain to products.
    The supply relief will not be coming from the big, national investments
    in the works right now by South Korea, the United States, and Europe but
    from older chip fabs and foundries running processes far from the cutting
    edge and on comparatively small silicon wafers.

    ... Despite the auto industry’s desperation, there’s no great rush to
    build new 200-mm fabs. ... More than 40 companies will increase capacity
    by more than 750,000 wafers-per-month from the beginning of 2020 to the
    end of 2022. The long-term trend to the end of 2024 is for a 17 percent
    increase in capacity for 200-mm facilities. Spending on equipment for
    these fabs is set to rise to $4.6 billion in 2021 after crossing the
    $3-billion mark in 2020 for the first time in years, SEMI says. But
    then spending will drop back to $4 billion in 2022. In comparison,
    spending to equip 300-mm fabs is expected to hit $78-billion in 2021.
The only thing I can derive from this with confidence is that the chip shortage will continue until 2024.
sounds··on NASA validates revolutionary propulsion design for deep space missions
This was a smaller prototype. Unless they release a theoretical Isp model for scaling up the engine (which, would we believe them if they did?) we can't know for certain yet.
sounds··on Could you train a ChatGPT-beating model for $85k and run it in a browser?
Remember to discount the tax depreciation for the hardware and deduct any potential future gains from either reselling it or using it.
sounds··on AI-enhanced development makes me more ambitious with my projects
That may not be true in this case. Cheaper "second system syndrome" may allow maintenance to be perceived as a cost center.

The solution used by Linux Mint seems apt:

    # this file forbids snapd from being installed by APT.

sounds··on The secret joke at the heart of the Harvard affirmative-action case
To discriminate, whether by race or by alma mater, is innate; even if it is illegal it will still happen. Meritocracy is hard, and wounded when we characterize a flaw in a meritocracy as if that were judgment day.

Should we all abandon Harvard now? Nah, this battle is everywhere.

sounds··on Raytracing on AMD’s RDNA 2/3, and Nvidia’s Turing and Pascal
Since cache hit ratios are so central to fast GPU code, the tree structure doesn't have to be exotic, likely the secret sauce is how it performs in the caches.
sounds··on GPT-4
OpenAI can't build a moat because OpenAI isn't a new vertical, or even a complete product.

Right now the magical demo is being paraded around, exploiting the same "worse is better" that toppled previous ivory towers of computing. It's helpful while the real product development happens elsewhere, since it keeps investors hyped about something.

The new verticals seem smaller than all of AI/ML. One company dominating ML is about as likely as a single source owning the living room or the smartphones or the web. That's a platitude for companies to woo their shareholders and for regulators to point at while doing their job. ML dominating the living room or smartphones or the web or education or professional work is equally unrealistic.

sounds··on GPT-4
Nah, it's already being done for GPT-3's competitors and will likely be done soon for GPT-4's competitors

sounds··on Sapphire Rapids: Golden Cove Hits Servers
Assuming they had fab capacity to produce a hypothetical Epyc 13912k with 4.5GHz base clock, I think AMD still nailed the revenue sweet spot with their current mix. So maybe they're not strictly leaving money on the table, so much as it is a lack of demand for a high end desktop that doubles as a server.

Intel has to produce that kind of beast because they're currently slightly behind in some areas. AMD might lose money if they followed Intel's playbook right now.

sounds··on Hardware microphone disconnect (2021)
I appreciate the request because I tend to agree, though I wouldn't say "every chip can be hacked," but rather I would point to Apple's wavering commitment to privacy (with their recent tracking debacle [1] and previous privacy "mistakes" [2]).

Please, Apple, instead of engineering a better kill switch which requires me to trust you, just install an actual kill switch that I can see for myself does what I want.

Seems they concluded that it doesn't scale up. Can't find the source now.
sounds··on StarFighter 16 inch: 4K Coreboot/Ryzen Linux laptop
This new laptop has soldered-down RAM. It's due to the LPDDR5 which is only electrically able to reach 6400MT/s if the memory socket is skipped, so no blame for it. Just be aware.

sounds··on Alphabet Announces Fourth Quarter and Fiscal Year 2022 Results
Really I think the question is around "symbiotic relationship."

Google has failed to win decisively in the search result ranking arms race. Concrete example: sites that rip from stackoverflow have been ranking higher than stackoverflow in google search results. Other search engines fare worse.

If Google trained a discriminator that penalized these practices I think their search product would dramatically improve and the web as a whole might benefit - although tabloid article farms might sue.

I appreciate the willingness to give them a shout out, by name.

Not the first time I've had a brush with Rio Tinto.

sounds··on Bulldozer, AMD’s Crash Modernization: Front End and Execution Engine
Then they would have said "masking" instead of "folding"

Thanks for mentioning masking though, in case anyone thought we didn't already know about that. ;-)

sounds··on Bulldozer, AMD’s Crash Modernization: Front End and Execution Engine
Since OP didn't answer, it's probably multiplying terms by zero to mask them out.

Do you think Page and Brin really want to deal with this mess?
sounds··on Can the double-slit experiment distinguish between quantum interpretations?
I think what's being asked is if this is the best way to formulate a testable hypothesis.

It seems to pass a first scan here.
