Sci-fi authors Scalzi and Stross decry AI's dystopian impact on their craft

Sunset

I was with him until this part...

> Stross, however, admitted he "can see some circumstances where being able to train a local model on my work could be useful to me."

> "I'd quite like a tool (running entirely locally on my own hardware, with no cloud service and no copyright-thieving grifters making bank on it via subscription fees) that digests a manuscript and derives a scene-by-scene timeline, that I could then query interactively and use to plan my next round of edits," he wrote.

Sigh. You were doing so well.

(And by the way, even open weights models are generally doing mass theft. The amounts of data that are required for training an LLM can't really be sourced on public-domain content alone, and certainly couldn't be trained entirely on Stross's own work while still being remotely usable.)

A deep dive into Nvidia's Vera CPU and the Olympus cores that power it

Not a modified Cortex

It isn't a modified Cortex or Neoverse, and the resemblances are largely superficial.

There are both legal and technical reasons preventing modification of ARM IP - customers usually don't receive full RTL, and modification of what they do receive is prohibited except as officially-sanctioned parameterization options (ie, the now-defunct Built On Cortex program.)

Big Blue thinks small, again, with POWER tower

Sunset

Re: "now in deskside form"...

Not really a "return to form" - the S1012 was offered as a tower too, and the S1112 uses the exact same form factor options as the S1012 did. (Power11 as a whole is basically a minor refresh of Power10, so that's not really surprising.)

Sunset

Smaller than typical 2U

It's not mentioned in the article, but - like the S1012 before it - the S1112 is a half-wide system, so you can fit two of them in 2U. (It's a fairly weird form factor for an enterprise server.)

Arm64 on the desktop? It’s spendy and it’s sluggish

Sunset

Re: All of these things are not like the others

So... SBSA/SBBR, which ARM servers have been using pretty consistently for the last decade? Sure, it isn't as common on trash-tier SBCs, but it doesn't mean it doesn't exist.

Sunset

Bad conclusions

A better headline would be "a six-year-old ARM server part using an eight-year-old IP has poor single-thread performance." Which is kind of, you know, a "yeah, duh" moment. Altra is using a Neoverse N1, a slightly modified Cortex-A76 for server applications - the A76 is seven generations behind current ARM IP (A76, A77, X1, X2, X3, X4, X925, C1-Ultra.)

Modern desktop/laptop oriented parts - from Qualcomm, Nvidia, Apple - run rings around Altra for ST. Literally multiple times higher ST perf.

One man, two kernels, and a lot of RISC-V

Hard pass on slop

There is zero chance I would ever use something LLM-generated for the most critical aspect of a software system.

Non-x86 servers now nearly half the market, IDC says

Sunset

The decline of RISC/UNIX

"Across the last two decades, non-x86 servers accounted for less than ten percent of revenue, and most of that went to IBM which emerged as the last vendor of proprietary servers as Oracle lost interest in Sun and the likes of HPE decided they couldn't sustain businesses built on exotic architectures."

Even fifteen years ago, RISC + mainframe accounted for something like a third of all server revenue. Like if you look at 4q11 from Gartner, you end up with:

x86: US$9.38bn (67%)

Enterprise RISC: US$2.73bn (19%)

IBM Z: US$1.37bn (9%)

Other (Non-IBM mainframes, etc): US$430mn (3%)

In retrospect, it's amazing how quickly high-end RISC went from mainstream to fringe from about 2010 to 2015. I don't think it's totally impossible that x86 could suffer a similar decline, if it continues to lose ground in hyperscale deployments.

Gemini accused of 30,000-line code purge and fake recovery report

Sunset

Don't anthropomorphize it!

"According to the developer, Gemini later admitted that the consultation logs were entirely fabricated and generated solely to satisfy the project’s automated rule requirements."

Except Gemini has no idea why it did or didn't output specific text. It has no internal life. It has no motivations. It just barfs up text. If you ask "why did you make the moon explode", and the chat backlog has an indicator that the bot made the moon explode at some point, it will make up some vaguely plausible reason for it.

Europe built sovereign clouds to escape US control. Then forgot about the processors

Sunset

Re: ARM, that's a bad comparison; Trustzone is an architectural feature for creating secure enclaves, but as long as you're running your own firmware in your own system, you control what runs in that enclave. That's not true of an Intel processor, where the ME secure firmware is entirely proprietary to Intel itself, unmodifiable, and largely undocumented - and, due to enforced digital signature requirements, cannot be replaced.

AWS racks M3 Ultra Macs that boast specs you can’t currently buy

You used to be able to buy these...

Apple killed the 512GB RAM option in March, and the 256GB option a few days ago.

Fujitsu confirms mainframe biz to die in 2035, in time for quantum AI supercomputers to take over

Sunset

Re: I'm willing to bet that the hardware ...

Yes, though Fujitsu is likely to euthanize GS21 (and BS2000 and VME, for folks in Europe) in 2035 as promised. They've also been moving ahead fairly aggressively with EOL'ing the minicomputer family (ASP) despite the fact it still has several thousand customer sites.

Ruby Central in 'real financial jeopardy' following RubyGems maintainer ruckus

Play stupid games, win stupid prizes

Is this not the organization that conspired with Shopify to seize control of the Gem infrastructure because they thought people were being mean to dhh (who is on the Shopify board) over being publicly far-right?

Screw 'em.

Re: "panic spreads faster than Wi-Fi"

Honestly, that wording sounds vaguely LLM-y. They're fond of inserting flowery but nonsensical analogies.

Just did after five years.

The last supported version of HP-UX is no more

Sunset

It will be missed

It was a nice system, for a Unix, though the quality and general usefulness of the annual releases had been going down for a while - toward the end, they tended to be not much more than JVM patches and new (but still old) OpenSSL releases.

Quite a few Integrity customers are still on it, pending migration projects (almost entirely to Linux, but a few to AIX.) I had heard some hopes a year or two ago that maybe HPE would extend the EOL date, but seemingly no luck.

I can't tell if the author doesn't realize Photoshop already has a native Win/ARM port.

Re: HPC?

On price? Horribly. These are emphatically not marketed for HPC.

IBM and LzLabs to clash in UK court over Software Defined Mainframe

Sunset

Re: Please Explain

As far as I know, they're reimplementing IBM's system interfaces, not merely hardware emulation. They also seem to be bridging DB2 calls to Postgres on the host via a compatibility layer.

If they really have copied enough of z/OS to allow running real commercial applications with no z/OS license, that's rather impressive.

Sunset

Re: Isn't this... Hercules?

It is not, as far as I know, though I suppose I wouldn't be shocked if it uses some of Hecules's Z core emulation code. To the best of my knowledge, the Software Defined Mainframe product not only provides a hardware emulator but also a compatible implementation of z/OS syscalls - sidestepping the problems earlier emulators have run into with licensing an IBM operating system.

Will anybody save Linux on Itanium? Absolutely not

Re: There are many VLIW systems

Neither TileGX nor Kalray are really DSPs. Tilera was manycore "general-purpose-ish" - it ran Linux (a whiteboxed RHEL) in one image across the system, mostly for networking applications. They went in normal rackmount systems. I have one. Kalray runs Linux too (though they're still in the process of getting their Linux port mainlined) but can't do a single SMP image across all x hundred cores on the chip - they get sliced into partitions of a dozen or so cores, each with its own Linux image.

Tilera never made MIPS stuff. TPM decided they were MIPS based on... nothing, as far as I can tell, and then the claim acquired a life of its own. Their ISA was a 32b and later 64b VLIW with a dense 3-instruction 64-bit bundle.

Sunset

Ah, yes. The total failure that was a US$4bn business in 2008, at a time when Opteron system revenue was barely half that.

It was niche. It was always niche. It was high-end mission-critical, just like SPARC and Power, but in that niche, it did fine at one point (until the secular decline in that part of the server market as a whole.)

As for "hundreds " - the number is in the thousands, even now. There are individual HP-UX sites with nearly a thousand machines. I would guess there are at least a thousand OpenVMS/IPF sites and at least two thousand running UX. I wouldn't be surprised if the numbers are 2-3 times that. (Remember that while VMS is available on x86 now, the ISV ecosystem still largely is not - Rdb for instance.)

Sunset

There are many VLIW systems

Many, many VLIWs exist (and ship annually.) Some general-purpose-ish examples are the Kalray MPPA (alive) and the Tilera TileGX (less alive.) Of less-general-purpose VLIWs, a large and visible example is the Qualcomm Hexagon, which ships in numbers of billions of cores per year.

Sorry Pat, but it's looking like Arm PCs are inevitable

Sunset

The ARM PC ecosystem - ie, the Snapdragon machines - aren't custom DTBs and BSPs. They're more or less normal EFI/ACPI systems, though with some strangeness in the ACPI implementation that Linux is still adapting to.

Same goes for severs. SeverReady systems have basically the same firmware and system-discovery stack that x86 servers do. There is essentially nothing machine-specific necessary for an ARM server OS vendor.

Not everything is a Pi.

One door opens, another one closes, and this one kills a mainframe

Sunset

The 6000 family didn't die in 1989, actually! It got absorbed into Groupe Bull who continued custom-hardware development until about 2006 and sells the product line under emulation to this day. There's a handful of sites in North America and a few more in France.

Nice platform. 36-bit, ASCII, distinctly old school.

Stratus ships latest batch of fault-tolerant Xeon servers

Sunset

Re: interesting concept

Stratus has their own OS, VOS, which is a Multics-like system that runs on the ftServer hardware and competes directly with Nonstop.

Most ftServers run Linux or NT, but the "absolutely must have nine nines of reliability" lot run VOS.

Google: Turn off Wi-Fi calling, VoLTE to protect your Android from Samsung hijack bugs

Sunset

Good luck with that

Of the US nationwide carriers, only one even has a non-VoLTE voice capability left (T-Mobile) and that's straight GSM - and going away soon. A lot of modern phones don't even have a way to turn VoLTE off from the GUI.

Perhaps the mad rush to kill off GSM, UMTS/HSPA, and CDMA was actually a mistake?

Loongson

LoongArch is not MIPS-compatible. At most, it is MIPS-like. Read the ISA manual sometime.

Non-binary DDR5 is finally coming to save your wallet

Sunset

Re: Apple is testing 24GB stacks. Maybe.

No they don't. They use on-package LPDDR4X or LPDDR5, depending on the type, which is not (despite the name) DDR5 but is also not HBM (which requires an active interposer or equivalent.)

How GitHub Copilot could steer Microsoft into a copyright storm

Sunset

Re: No Solidarity with A.I.'s run for profit!

Cool. Time to move off GitHub, then, and to an alternative - and there are many - that respects the dignity of the creator and the worker.

Sunset

Re: I am not a lawyer

They are members of the ownership class, and you are not. Different rules apply... isn't it grand?

Sunset

Re: No Solidarity with A.I.'s run for profit!

Well put.

There is a big difference between a) putting my effort into an application for my community, or assisting my fellow worker, and b) working for free to create a paid-for service that will assist capital in profiting off of replacing labour.

No way. That's abhorrent.

IBM expands Power10 line-up with four new systems

Sunset

Re: Power vs x86/64

Much of the userbase of IBM i - the System Formerly Known As AS/400 - is smaller companies that bought into the platform years ago and have seen no reason to fix what ain't broken. AIX users tend to be large, but i users span the full spectrum from "fortune500 megacorp" to "auto parts shop in Peoria."

Sunset

Re: Power vs x86/64

Some combination of...

-Direct-attached NVlink for GPUs (relevant to Power9, not particularly relevant for Power10)

-Very high memory bandwidth

-Very high scalability (glueless to 16 sockets)

-Acceleration features not present on Xeon (compression, decimal floating-point for business math)

-High perf/core (especially matters if you're running per-core-licensed software like Oracle)

And most importantly, since most customers are legacy AIX or i...

-Compatibility with previous Power systems
