AI bands, managed by an AI manager, with all profits going to a venture capitalist holding the power on the LLM's

There shouldn't be any profits. An AI can't hold a copyright.

Anything produced by an AI is public domain, and anyone can redistribute its works without limitations, for their own (small) profit if desired.

Pretty much only by lying, claiming to hold the copyright on the works, can someone profit off of AI produced music.

Re: What about drive caddies?

OCP doesn't stuff a few hard drives in the front of each server... No, they'll have one 4U storage chassis with 72 3.5" drives as storage for a whole rack of servers, like the "Grand Canyon Storage System":

Thumb Down

Changing the wrong dimensions...

I don't get it. The idea was that rack frames waste space so OCP made the inner diameter larger while keeping the exterior diameter the same... Wouldn't doing it the other way round have accomplished just as much space-savings with fewer retoolings? Everybody will be dependant on 19" adapters for many years to come, and I wouldn't be surprised if it doesn't catch on and they end up back on 19". Hell, manufacturers will just be sticking their standard gear in a wider case, anyhow, with only drive backplanes getting a redesign.

The cooling issues with servers are because of the limited VERTICAL space, anyhow... Fans are square (or round) so the smaller vertical size is the limit, not the horizontal, that's why "blade" enclosure and Dell's 4x nodes in 2U enclosures (eg. C6400) make some sense. Servers only half a U wide but 2U or 3U tall can have far more efficient cooling, while taking up less rack space.

Datacenter water use? California governor says don't ask, don't tell

rcxb Silver badge

Re: California water politics is already a corrupt oligarchic kleptocracy

but taking full advantage requires massive amounts of water to be pumped in from elsewhere, and the state's endless willingness to do this

That's not unique to California at all. Farmers all over the US are pumping record levels of ground water for their crops.

rcxb Silver badge

Re: California water politics is already a corrupt oligarchic kleptocracy

Those are EXPORTS to other countries

You're just nit-picking what happened to be a convenient source of info. If you've got a source that says California is NOT the single biggest producer of dairy products in the US, by all means post it here. (Hint: They took the crown from Wisconsin in 1993 and kept it ever since).

farming a water intensive food like rice in a desert

California is NOT a desert. The San Joaquin Valley is NOT a desert. It is classified as a Mediterranean climate.

California does have deserts, but with tiny exceptions, that is NOT where the agriculture is.

if the rice farmers had to pay the true cost for their water that rice would cost many times rice produced in wetter states or imported here.

The only way in which California is unique here, is that it is a rich and heavily populated state, so you can claim water rights in a free market would be absurdly high.

The majority of US farm land is consuming water at unsustainable rates. See The Ogallala Aquifer "which yields about 30% of the ground water used for irrigation in the United States.[5] The aquifer is at risk of over-extraction and pollution." https://en.wikipedia.org/wiki/Ogallala_Aquifer

A lot of crops can't be moved to a wetter area, in any case. Most crops only handle a narrow range of climatic conditions. So, putting a stop to agriculture in California will simply mean less food grown in the US, and more imported from foreign countries. Water rights may need to be reformed, but this anti-California hysteria, misinformation, and pot-shots, isn't helping anyone.

"a $2 billion investment by a United Arab Emirates state-owned enterprise in the Binance crypto exchange using the Trump family’s stablecoin asset. An unknown number of billions placed by Qatar in a Trump-family real-estate development in that emirate, topped by the gift of a 747 luxury jet for the president’s personal use in office and afterward. Government-approved support for a Trump golf course in Vietnam while its leaders were negotiating with the United States for relief from Trump tariffs. Last week, Trump hosted more than 200 purchasers of his meme coin, many of them apparently foreign nationals, for a private dinner, with no disclosure of the names of those who had paid into his pocket for access to the president’s time and favor."

"Trump has been inundated with cash from Middle Eastern governments. Obscure Chinese firms are suddenly buying millions of dollars’ worth of Trump meme coins. So are American companies hard-hit by the Trump tariffs and desperately seeking access and influence."

Those are all niche products, and if they disappeared from our stores or doubled in price no one is going to be all that put out like we would be if bread, milk, eggs, chicken, bacon or beef go up in price.

China moves to extend control over tech industry's critical rare earths

rcxb Silver badge

And in the interim…?

Several things:

****

The West is recycling rare earths to escape China’s grip

In September 2024, the U.S. Department of Defense invested $4.2 million in Rare Earth Salts, a startup that aims to extract the oxides from domestic recycled products

"With slowing EV uptake (in the U.S.) and mandates to convert from ICE to EV formats receding into the future, the imperative for replacing Chinese-sourced materials in EVs is declining," said Christopher Ecclestone, principal and mining strategist at Hallgarten & Company.

"Pretty soon, the first generation of EVs will be up for recycling themselves, creating a pool of ex-China material that will be under the control of the West," he said.

https://www.cnbc.com/2025/05/28/china-controlled-rare-earths-account-for-3-pounds-of-an-electric-car-ev.html

****

Another option to conserve dwindling magnet supplies is reverting to older electric-motor technology that doesn’t make use of rare-earth magnets. Carmakers stopped using those motors because the current versions are cheaper and more efficient.

Carmakers are also considering stripping out some premium features, such as adjustable seats, that make use of several tiny electric motors. High-end speaker systems that use rare-earth magnets could also be replaced with downgraded versions.

https://www.wsj.com/business/autos/car-companies-production-rare-earth-shortage-aaf87ad2

****

USARE is pursuing a cautious, phased approach to growth. The company intends to begin producing magnets at an annual rate of 600 metric tons early next year, before doubling that amount by the year’s end. A few years from now, this factory is expected to make 5,000 metric tons

https://www.washingtonpost.com/business/2025/06/22/us-rare-earth-neodymium-magnets-china/

****

"We are on track to meet our goal of a sustainable mine to magnet supply chain capable of supporting U.S. defence requirements by 2027," Assistant Secretary of Defense for Industrial Base Policy Laura Taylor-Kale said at a mining conference in Perth.

The U.S. this year extended its support for the first time to back two Australian-listed rare earths projects with up to $850 million to help build out the supply chain. It has already funded Australian producer Lynas Rare Earths (LYC.AX), the world's biggest producer outside of China, to build a new rare earths processing facility in Texas.

Government support for the sector is also coming domestically. In Australia, the federal government has pledged a A$1 billion ($667 million) loan to mineral sands producer Iluka Resources (ILU.AX) to build a new minerals processing plant on the country's west coast.

Strange that on discussions of semiconductor restrictions, commentors here are certain China will just up and surpass the rest of the world in no time flat. But when China restricts rare-earths, everyone acts like it's game-over.

There are viable alternatives for rare-earths in many use-cases. It's just that they were cheap and a bit more efficient, so companies put them in everything. With the difficulties sourcing them, some equipment can be redesigned, while others will just have to be sourced from non-Chinese rare earth deposits. China holds a majority of productions, but the rest of the world has been working for years to removing its dependency on China. It won't be long before China's share can be cut-out entirely, then they'll have to write-off their years of investments.

"In a decade, we shouldn't need China for rare earths and permanent magnets." said Dr Gracelin Baskaran, director of the Critical Minerals Security Program at the Center for Strategic and International Studies - https://www.theregister.com/2025/08/26/trump_china_rare_earths/

Intel's open source future in question as exec says he's done carrying the competition

rcxb Silver badge

Re: Intel's Open Source future not in question

That they're stating there is a problem and exploring options to make more money, says there will be some changes. Maybe they'll just start cutting the open source software projects that are less popular, maybe they'll be keeping more of their code as proprietary, or maybe they'll try some more restrictive open-source licenses that'll be sure to enrage their customers.

Either way, it's clear they don't see what a competitive advantage their software already gives them, and are at serious risk of killing this golden goose, too, just as they did with their lead in fabs by under-investing there.

the entire modern Wintel ecosystem only exists because companies copied the IBM PC and some enhanced it…

The "IBM PC" was just commercial off-the-shelf components. IBM's BIOS was the only part that needed to be reverse engineered, and that only for systems trying to manage 100% compatibility. After IBM clones appeared, manufacturers took over developing the "standard" and didn't need or wait for IBM's plans or blessing.

It didn't have to be MS-DOS on IBM PC compat that took over. Other standards like CP/M on S-100 machines (Intel or Z80 CPU) was a modestly successful standard that could have done the job. Instead it just led the way for Intel/IBM/Microsoft. If IBM had waited another year or so, the PC world might have run on m68k compatibles instead of Intel compatibles, but we'd probably have gotten to exactly the same spot, maybe even faster.

Re: DEC Alpha and LN03 laser printer so could do rudimentary word processing

Back then the only alternative on Linux was an alpha version of abiword, IIRC.

The WYSIWYG HTML editor that came with Netscape Communicator ("Composer") was my preferred document editor on Linux, years before AbiWord and for years after. While printouts were most common, nobody I sent docs to could claim they couldn't read them, whereas the world was a mix of Microsoft Works, Microsoft Office, WordPerfect/Quattro, iWork, etc. HTML seemed the sane way to go. Much like PDF export is, these days.

The buzz around AbiWord was its (rather iffy) Microsoft Office file compatibility. That mattered quite a lot at the time (much more than today). Older versions of WordPerfect didn't offer that. And if you didn't need to read/write MSOffice file formats, there were MANY office suites for Linux to choose from. I remember trying half a dozen on Linux, small and large, of varying stability and feature-completeness, before Sun open sourced StarOffice and everyone focused their efforts there. Incidentally, KWord (KDE) appeared at the same time as AbiWord (adopted by GNOME).

Re: Get The Source

by Dave Plummer, an ex-DEC and early Microsoft engineer

Nothing in his bio mentions working for Digital / DEC.

Dave Plummer has also admitted to setting the size limits for Fat32 drives.

He did make that claim, but his statements are riddled with inaccuracies:

He claimed it was done for NT4 in "1995, 1996." But NT4 never had FAT32 support; not until Windows 2000.

His claims about tiny flash sizes also align with NT4 and not Windows 2000.

He claimed that rationale was that flash drives were only a few MBytes at the time, but back in 1996 it was common for people to format partitions on their NF4 hard drives as FAT16, for interoperability with Windows 9x, DOS, and more. (Unlike today, no other OSes had NTFS support back then). It made sense to do the same with FAT32 and hard drives were certainly nearing the 32GB limit when Windows 2000 was released.

It's far too convenient to claim the 32GB limit was an accident, when Microsoft really wanted to push their exFAT file system, and got many millions in patent licensing fees from Android phone manufacturers to include exFAT. While FAT32 was old enough to lack the same patent protection.

Re: Really!

It is entirely possible to power the world with only solar. You'd need a series of huge installations along the equator

Nonsense. Solar panels do not need to be installed anywhere near the equator. That's not even the best location. The best places for solar are deserts, which China, the US, and Australia have plenty of, and they're pretty empty...

Even in less than ideal conditions, PV is immensely practical and cheaper than any other option (excepting wind). Germany is a good example. Solar panels are practical and economical even in Alaska.

"Solar energy could theoretically cover the world's electricity demand by just 0.3% of its land area."

Unlike Russian gas, those Chinese solar panels will just continue operating for the next 30 years, no mater how the geopolitical situation changes. The sooner they get installed, the better.

Re: Really!

The energy output of solar panels is proportional to the cosine of the sun's angle away from "directly overhead" and the BEST case scenario is that 70-80% of the total joules produced happens between 10am-2pm local solar time and essentially zero revenue output occurs if the sun is less than 30 degrees abover the horizon

The traditional horizontal mounting is not the only way to install solar panels. Large installations from decades ago were motorized with solar trackers to maximize output.

Today, vertical bifacial panels are proving a more efficient option at higher latitudes, in rainy/snowy conditions, etc.

Re: Krasnov

There needs to be a distinction between the Supreme Court ruling in the administration's favour (which it has done very little of, and mostly AGAINST the Trump administration) and the court's "emergency docket" rulings, blocking injunctions from lower courts (which it has done a lot of) allowing Trump's actions to temporarily remain in place until they work their way through the courts.

The former would be declaring Trump's actions legal, while the later do not even offer even a whiff of an opinion on eventual legal rulings.

The legal system moves slowly, and in the end, may (or may not) rule most of Trump's actions illegal.

There are plenty of examples of this.

Popular catch-phrases Trump hated but reluctantly repeated, worked well enough to get him into office.

Trump's first term was filled with examples of Trump's executive orders being overturned by the courts, because he couldn't keep his mouth shut and supidly said something that made it clear his motivations were illegal.

It was Republicans in congress before Trump ever entered politics that obstructed Democratic administrations from nominating judges, including to the Supereme court, which left vacanies for Trump to fill, with loyal judges who later ruled in his favor in violation of decades of judicial precident.

rcxb Silver badge

Re: Don't Panic

Never really understood why it was there, and if so why it could not be disabled

It's easily turned-off... "tinker panic 0" at the TOP of your ntp.conf will do it. Seems it was added around v4.0, in the late 1990s. I'm not sure if NTPv3 even had a panic threshold, but in any case, the normal procedure was to run "ntpdate" against a trusted server, to jump the date/time, *before* you start ntpd. This configuration was common in startup scripts of the era.

The panic threshold is there to protect against buggy or malicious NTP servers. Setting your system date backwards will break time-sensitive things like "make". Setting your date backwards also allows using expired TLS certificates that may have been compromised.

Another issue was an alarm server going into meltdown when the NTP caused the clock to go back one hour

Well, you've provided a reason of your own... NTP will "slew" the time (see: "man adjtime" ) instead of jumping it backwards, but that's only practical for smaller adjustments and would take an absurd amount of time to get in-sync.

Re: You are very brave

My above comment on IO might be misleading to non IBM pros.

Those "two Intel PCIe NICs" or "couple Fibre Channel" I referred to are each one "card" and IBM mainframes accept about a dozen cards in each I/O cage. Larger IBM systems may have more I/O cages, but it's common for a single rack mainframe to only have one I/O cage.

In the old days, when x86 servers were single core, and NICs didn't have ToE, mainframes certainly could push more I/O than commodity servers. But now? Not so much.

Re: You are very brave

For applications that actually need the kind of guaranteed uptime and throughput mainframes can provide, there's no cheaper alternative.

I've seen z/OS and VSE crash plenty. Linux on x86 servers can easily run longer...

Mainframes do have slightly better RAS than a single x86 server, but not better than even a small cluster of them. IBM spends on lot on marketing, and the best they can come up with is that the "Mainframe" might be 99.99999% reliable, while a single x86 server (at 1% of the price) is only just 99.9999% reliable. While hand-waving away that it is the hardware is reliable... NOT their proprietary operating systems that run on it.

Mainframe IO is literally two Intel PCIe NICs in an enclosure... Or a couple Fibre Channel cards for SAN. You can *easily* have far more IO in a rack full of x86 servers than on a single 48U rack IBM mainframe.

Disclosure: I'm a senior z/VM & Linux on Z (s390x) admin. I manage several mainframes, and support several sysprogs...

Re: You are very brave

Frankly, breaking-out of that proprietary platform lock-in was probably still a good move. The longer companies continue to update their in-house software on the mainframe, the more expensive it gets to transition off. Even if the first go-round was more expensive than planned, commodity hardware quickly got much faster and much cheaper over the years, and generally required less labor than IBM.

Companies that never made the jump, still running business-critical functions on their mainframes, sure wish they had done such a transition long ago.

No more Blocktoberfest? German court throws book at ad blockers

Felony Contempt of Business Model

However, online advertising is also one of the primary ways that publishers pay their bills. Ad blockers prevent those publishers from earning the revenue they may need to stay in business.

It's not a crime that I do something that happens to not help your business model succeed. Down that road lies outlawing bicycles to improve Volkswagen's sales and restricting the size of kitchens in private homes to ensure people will go out to eat at restaurants more frequently.

Before Adblock and uBlock, I used Privoxy, Internet Junkbuster before that, and null-routing in the hosts file before that. In fact I still do use DNS66 on Android to prevent apps loading ads.

I can tell you, you don't want to go back to that. Ad blocking browser extensions do a much better job with better performance, less site breakage, and less effort from you. Publishers are privy to domain blocking, and work around it by intermingling their ads with normal site images, use obtuse file/path naming to prevent easily singling out their ads, and can even proxy connections to other domains through their own server.

The solution, if German courts make the wrong decision here, is just integrating ad blocking into web browsers... Then it's unambiguously a setting in the browser deciding not to fetch or display certain elements, rather being arguably any modification of the website's copyrighted code. No more intrusive than changing your web browser's font settings...

Re: Flawed technology

I don't see why Tesla can't have locks to where speeds can't be set for more than 9mph over the posted limit.

I've hit areas where there was apparently construction in the recent past, so my navigation app was convinced I should be going 25MPH, instead of the posted 50MPH.

Tesla can't depend on every municipality posting up-to-date speed limit information. There's no law requiring them to do so. The driver would still be liable for creating a traffic hazard.

It's silly to claim Tesla should put error-prone training wheels on their cars, while all other cars on the road have none at all, and drivers can slam down on the accelerator as hard as they want. After all, it's not the Tesla vehicles that get a license to drive on the roads, it's the drivers.

Re: Flawed technology

End of the article it says the driver had his foot on the accelerator, so we're not even talking about cruise control (adaptive or otherwise).

Re: Flawed technology

are there roads with a 70mph speed limit that end abruptly at a STOP sign?

Many interstate freeway off-ramps in the US meet that description.

You are expected to slow down, of course. In urban areas there may be a speed limit sign part-way down the off-ramp indicating a reduced maximum speed, but that extra signage is uncommon in low-traffic areas outside of major cities.

For an example I just looked up, try I-40's Fort Rock Rd off-ramp in Arizona.
