xxpor··on Red Hat being phased out of existence?
Essentially every single electronic financial transaction that you do (outside of crypto exchanges) involves an IBM mainframe. A huge number of businesses run on top of IBM I (like Costco).

It's plenty alive, just not as much inside of Silicon Valley itself.

xxpor··on Understanding is the new bottleneck
This seems like one of the hardest parts for everyone to adjust to (including myself): code is now easy come, easy go. Or in other words, everyone seems to get trapped in the sunk cost fallacy, even if there's not even that much sunk cost any more!
xxpor··on Study links GLP-1 drugs to bigger jump in women's employment than a degree
>If everybody improves their looks, the net effect will be zero.

I'm not sure that's true. I think there's a baseline issue here. Regardless, even if it netted out to zero, you'd end up with a different order of who gets hired when, so for any individual it'd still make sense to try to improve your looks.

xxpor··on Exploiting System Management Mode with a very long interrupt
Maybe with vfio/igb_uio/uio_pci_generic? Still root level access.
xxpor··on Exploiting System Management Mode with a very long interrupt
Can this be patched? Is there a chance it's a hw watchdog that you can't fix in microcode?
xxpor··on Intelligence Is Not the Main Bottleneck
But humans have used AI with ingenuity.
xxpor··on America has become an entrepreneur's paradise
How much has section 199A encouraged this?
xxpor··on The drivers behind software delivery inefficiency
It's funny, because LLMs have context switching costs too! Cached tokens cost less than non-cached. There's no reason to think that doesn't apply to humans.
xxpor··on Markets are competitive if and only if P != NP
Unless and until desktop OSes make typing symbols not on the keyboard as easy as iOS or Android, I can't be bothered.
xxpor··on Markets are competitive if and only if P = NP
Seems like t is a very critical variable then. For example, you could imagine a particular market is "perfectly" efficient at the moment (however you want to define the boundaries of a particular market), and there is no opportunity. But then a completely unrelated company or university makes a fundemental advancement in materials science that fundamentally changes the landscape. An exogenous shock in other words.

In a certain sense I guess this is why every anti-trust suit fundamentally comes down to defining the market bubble more than anything else.

xxpor··on Markets are competitive if and only if P != NP
The actual paper's title is

"Markets are competitive if and only if P != NP"

Seems that HN's auto-headline rewriting in this case has made a critical error :)

>Artificial intelligence, by expanding firms' computational capabilities, is pushing markets from the competitive regime toward the collusive regime, explaining the empirical emergence of algorithmic collusion without explicit coordination.

I have to dig more into the paper but I don't see how this follows, except in the most straightforward way. Basically, if everyone uses the same methods to derive price, of course there will be "collusion", or in other words, everyone will have the same price. But this doesn't seem like a result of compute per se, but simply better communication networks and information flows. You could have gotten the same result in medieval England by having everyone post their selling prices on the town square board.

Again, I haven't dug into the paper yet, but it seems like what really matters for firms is "compute"/$ (if the "compute" is an LLM or an assistant that has to go walk the 10 minutes down to the square makes little difference)

Edit: Isn't another implication of this, that increased compute -> collusion imply that increased compute -> communism becomes feasible?

I think this goes to my point above though, the primary problem preventing fully automated luxury communism isn't compute per se, but actually observing the information flows to make it possible. Capitalism famously solves this information problem through the pricing mechanism. So in effect, he's arguing that extra compute makes information gathering more efficient, and at the limit you get perfect information. Which, yeah, I guess so. Assuming everything can be perfectly measured, even theoretically.

xxpor··on Claude Sonnet 5
The world is not zero sum. Value is created, not just preserved. Anthropic and OpenAI creating value does not imply that smaller guys can not also create value.
xxpor··on Apple raises prices of MacBooks, iPads
The MacBook Neo (at least pre announcement) was a better value than anything else, including a chromebook.
xxpor··on IBM debuts sub-1 nanometer chip technology
Approximately everyone (at least in the F500) outside of Big Tech uses them. For example, Costco's entire inventory management system runs on IBM i (so, POWER). You can see the classic terminal look around the store. Banks run a TON of z and i. You'll never see them because they're essentially always in data centers, but I guarantee you interact with them even if it's very non-obvious because there's 50 microservices between the UI and the actual system of record.
xxpor··on Digital euro clears key hurdle as EU seeks to break free from U.S. credit cards
Europeans being so scared of debt is so funny. Just pay off your card every month.

The liability model is completely different in the US from Europe w.r.t. merchant vs bank.

The interchange fees are much much higher in the US, which is what pays for the rewards. Europe has an artificial cap.

xxpor··on Open Source for IBM Z and LinuxONE
What does an open source dev get out of their work at all? Satisfaction?

For the "traditional" open source model of give away the software and sell the support, s390x customers could be fantastic customers: love paying for support, lots of $$$, super sticky once you get them.

But yeah for a random indie dev the PITA makes it harder.

xxpor··on Ubiquiti: Enterprise NAS, Built on ZFS
You can hit 10 gig aggregate on an A57 quite easily, given standard memory bandwidth (I've done it). They must be doing something stupid on the software side, like too many copies. Or if you're trying to shove 10 gig in one flow at 1500 mtu yeah that might be painful.

This is the difference between the people on this site broadly and everyone else broadly.
xxpor··on 10Gb/s Ethernet: switching to a Broadcom SFP+ module
I gotta say this is the kind of stuff that LLMs make trivial to answer these days.
xxpor··on 10Gb/s Ethernet: switching to a Broadcom SFP+ module
IIRC it's code :( Very silly IMO.
xxpor··on 10Gb/s Ethernet: switching to a Broadcom SFP+ module
Doing the cabling job was a weekend long project for me, I just never want to have to do that again (yes yes I should have run conduit and pull strings, but single mode just means I didn't have to even do that)
xxpor··on 10Gb/s Ethernet: switching to a Broadcom SFP+ module
I think this is the first time one of my comments has ever gotten mentioned in a subsequent post, so that's cool :)

Glad it was helpful and not me being an idiot. That's a shame about the temp read out. I just checked my MikroTik and can see the same thing. In fact, the only SFP module reporting a temperature at all is the real fiber one, all of the DACs/converters report nothing. No voltage either.

I'd guess that the mediatek blobs are exactly 64k, and mostly 0s?

xxpor··on Let's Encrypt bans certificate usage in any US sanctioned territory [pdf]
No remotely western company will risk US sanctions violations or whatever other regulatory burden by using US technology where it can't be used. Even Chinese companies depending on how state backed they are might not be willing to risk it.

Do you really think the EU wants to sign up for PR that’s essentially “the US is being too mean to Russia” right now?
xxpor··on Let's Encrypt bans certificate usage in any US sanctioned territory [pdf]
The RISC-V move was laughable. It’s still US tech, developed largely with DARPA funds.
xxpor··on I tested every IP KVM in my Homelab
I've been interested but the idea of SPI flasher recovery has always meant I've not bothered actually trying. Maybe I will finally on one of these old boards I have lying around..
xxpor··on I tested every IP KVM in my Homelab
Part of the problem is the absolute crap that most vendors throw on an AST2600 is even worse.

I will say iDRAC has been a lot more reliable for me, but the chance I'll ever buy a Dell server for home use is basically 0.
