harshreality··on Under new law, cops bust famous cartoonist for AI-generated CSAM
They don't have to sell imagery, or intend for it to be publicized, for it to have the effect of driving demand for such imagery.

The link between consumption (without purchase) of CSAM and increased production of CSAM is assumed in the same way, isn't it?

The motives and situational dynamics of pedophiles filming child pornography, and gangs robbing or carjacking people on video in broad daylight, may be different in some ways, but in some ways they're not: both get direct benefit from the crime, regardless of the recordings; in both cases some (small) subset of people interested in watching the recordings may become more inclined to act out what they see, if it aligns with an already existing inclination toward pedophilia or violent crime. That's independent of whether they can make money or become famous for the crime, although money or infamy as additional motive is an additional problem.

harshreality··on Under new law, cops bust famous cartoonist for AI-generated CSAM
The few studies on "video games cause violence" I've seen have been extremely limited in scope. They're too concerned with short-term frequency of playing particular games, or desire to play them. They're not concerned enough with the influence of being quite familiar with such games, or how cultural prevalence of such games normalizes thoughts of certain behaviors and shifts the Overton window. There are also selection bias problems. I'd expect media and games to more greatly affect people already psychologically unstable or on the criminal fringe... not people likely to be study participants.

Studies on sexual violence and changes in that over time have even more problems, for example how difficult it is to get average people to report accurately about their private relationships. Those people likely to volunteer accurate information are not necessarily representative.

I'm somewhat sympathetic to that argument. However, it doesn't stop there.

Violent video games prove contribution to market demand for FPS-style videos of mass shootings or carjackings, so can/should we ban Call of Duty and Grand Theft Auto now?

(Note that the "market demand" argument is subtly different from the argument that the games directly cause people to become more violent, either in general or by encouraging specific copycat violence. Studies on [lack of] direct violence causation are weak and disputed.)

harshreality··on ZFS 2.3 released with ZFS raidz expansion
Why are you considering raid5/6? Are you considering building a large storage array? If the data will fit comfortably (50-60% utilization) on one drive, all you need is raid1. Btrfs is fine for raid1 (raid1c3 for extra redundancy); it might have hidden bugs, but no filesystem is immune from those; zfs had a data loss bug (it was rare, but it happened) a year ago.

Why use zfs for a boot partition? Unless you're using every disk mounting point and nvme slot for a single large raid array, you can use a cheap 512GB nvme drive or old spare 2.5" ssd for the boot volume. Or two, in btrfs raid1 if you absolutely must... but do you even need redundancy or datasum (which can hurt performance) to protect OS files? Do you really care if static package files get corrupted? Those are easily reinstalled, and modern quality brand SSDs are quite reliable.

harshreality··on Why was there a wall near runway at S Korea plane crash airport?
It doesn't make sense, though, that it would have to be concrete-reinforced above ground, and non-frangible, just because the area floods.

Maybe it's the cheapest way to engineer the ILS localizer to be flood-resistant? I don't know.

harshreality··on In Memoriam: Noah Gibbs
I consider almost all deaths of people I don't know personally as a Schrödinger's box of possibilities. There's usually no need to collapse them. Except in cases where it's obvious, such as extreme sport accidents, there's no way to know for sure. Even terminal patients could resort to assisted suicide, which is ambiguous; is that suicide, or dying from the disease? A cause of death stated by relatives could even be an outright lie.

"Lost battle with <disease>" could be used to refer to depression -> suicide. "Sudden [cardiovascular event]" or "died in their sleep" could be suicide or overdose. etc.

harshreality··on Jeju Air Jet Crashes in South Korea With Over 170 Dead or Missing
Panic is understandable momentarily, but any professional pilot should be able to overcome that within a few seconds, and remember their training, which in an emergency is something like aviate, identify the problem if possible, and run checklists. Panic doesn't solve anything, and there's a comfort in having checklists and procedures to run. Something must have gone very wrong in training or with the plane for this to happen.

There's a standard short checklist for landing that includes flaps and landing gear. There may also be an emergency landing checklist that would also include those things.

The voice recorder and flight data recorder almost certainly survived. We'll know more after those have been recovered and analyzed.

harshreality··on "Nvidia is so far ahead that all the 4090s are nerfed to half speed"
I'm ambivalent about this sort of thing (or, as another example, Intel's CPUs many years ago that offered paid firmware upgrades to enable higher performance).

On one hand, it's very bad because it reduces economic output from the exact same input resources (materials and labor and r&d).

On the other hand, allowing market segmentation, and more profits from the higher segments, allows more progress and scaling for the next generation of parts (smaller process nodes aren't cheap, and neither is chip R&D).

harshreality··on What will enter the public domain in 2025?
Encoding efficiency for a given perceptual quality is very important when you pay for bandwidth or disk space.

Otherwise there would have been no effort to create vp9 and av1, as everyone on that side of the codec wars would've stuck with vp8.

harshreality··on Rapid colonization of a space-returned Ryugu sample by terrestrial microorganism
What's the point of all that effort if those habs are going to be one-way trips for the people going there? What are they going to accomplish in their floating or underground habitats? They're not getting back to anywhere useful from either place. They're not going to survive without frequent Earth resupply[1]. Whether habs could exist is an interesting thought experiment, but that's all it is for the foreseeable future.

Even a sizable Mars colony probably won't survive without frequent Earth assistance. The Mark Watney fantasy of growing food in Martian dirt with a little added fertilizer: mostly debunked[2]. The most sustainable case—for the foreseeable future—is probably a Biosphere2-like environment, where everyone hopes there's no accident, sabotage, or environment-caused damage. How many Starship missions would it take to get enough materials to Mars to build one Biosphere2 to support 8 people?

I agree with you that meaningful colonization of Mars is not serious. I just think the prospects on the inner inner planets are even more absurd than on Mars. In a floating Venusian hab, you could generate breathable air and not much else. Underground on Mercury, getting breathable air might be a problem, but you can import—at great cost, that delta-v is brutal—anything you can fit on a suitable rocket.

There's no point to any of this except as research stations or jump-off ports, and for that Mars is the obvious choice: we can make hydrocarbon fuel there, and the surface isn't equipment-melting. But where would we be jumping off to? We have nothing planned, and no particular reason, to send humans to Europa or anywhere else.

[1] How do you resupply a floating habitat on Venus? Even if you could, the constraints and resource limitations of a floating hab would be even more severe than for an underground, resource-poor Mercury hab.

harshreality··on Teen behind hundreds of swatting attacks pleads guilty to federal charges
It is, because cops never shoot someone just for being armed. They just don't. It's a combination of being armed plus (believed) criminal status, or behavior during the encounter.

(And it's exceedingly rare that cops will believe an upstanding citizen who's legally armed and behaving civilly is a criminal. It happens, for instance in the two cases I cited, but it's rare. They're a rounding error in the police killing stats.)

harshreality··on Teen behind hundreds of swatting attacks pleads guilty to federal charges
"Armed" is a proxy for criminals being criminals, and almost always reaching for, displaying, or using the weapon in some antisocial way prior to being shot dead.

Legal gun owners not committing obvious crimes are only rarely accosted by police, and shootings are exceedingly rare, and they usually make the news and result in legal action. They also usually involve the victim doing something that's not advisable, even if they're not doing anything legally wrong. Philando Castile, for instance, or Johnny Hurley.

"Unarmed" doesn't represent what the suspect was doing that got them shot. Were they resisting arrest or being noncompliant and reaching for their waist or a center console or glove compartment?

There are cases where police shoot suspects, armed or unarmed, unjustifiably. They're not as rare as anyone wishes they were. They're still fairly rare. Behaving civilly, even while recognizing that many police are like barely constrained wild animals, goes a long way toward ensuring that an accidental furtive gesture isn't interpreted as reaching for a weapon.

harshreality··on NY Times gets 230 wrong again
I think the author is right that harms caused by incorrect content aren't—and shouldn't be—the fault of section 230, and are instead the fault of the original producers of the content.

I think the author is wrong in claiming that modern attention-optimizing recommendation algorithms are better than more primitive, poorer recommendation algorithms. Appearing to be more engaging/addictive does not imply more value. It's a measurement problem.

harshreality··on QBittorrent: Open-Source, Lightweight BitTorrent Client with No Ads
If the VPN container does things correctly and kills the default non-vpn route, how would those surprises occur? To be clear, I hope 3np is talking about containers like the following, and not trying to proxy only udp or only tcp piecemeal.

harshreality··on CA law means stores can't say you're buying a game if you're merely licensing it
There has to be some implied period of time for which it's fully usable.

No sane court is going to uphold an adhesion contract where someone pays $100 for a substantially multiplayer game (e.g. not Portal 1) yet the publisher is allowed to disable servers required for the game's multiplayer operation a week later because they cost money to maintain and the userbase hasn't hit targets.

harshreality··on Damn Vulnerable UEFI
How do you build a BIOS successor that's not complicated, when it has to be able to reflash bios from a file on a fat32 partition on a usb stick, because all the other historical ways of reflashing bios were difficult and more fragile? How do you build a BIOS successor that's not complicated when it needs to allow an OS to alter boot settings for the next boot?

Granted, most of what goes on in a BIOS is displaying and changing variables involved in getting the system running, and maintaining those values, which just requires some sort of minimal editing interface and nv storage, but then... users appear. They want to be able to use a mouse. They want an ability to configure their raid chipset prior to boot, or netboot, and HW makers want to implement that in a way that's not some arcane raw assembly dance between BIOS and additional chip FW. What then?

I don't think the complaint is about complexity, but about code quality and architecture. This isn't the only case where an old, simpler but less capable and annoying, system has been replaced by a much more complex system that is much hated and [initially] buggy and less secure, but also more or less gets the job done better than the old way, and where average users of the new system find it easier and more productive.

If there wasn't a case where a hardware manufacturer needed a capability prior to the OS taking over, or to modify their HW settings from the OS in a portable way, it wouldn't be in UEFI, right?

Calling UEFI a full operating system seems needlessly inflammatory. It's not a linux or windows kernel. It has to do a fair amount of the basics, but so does any kernel running on a general purpose chip and interfacing with a bunch of other people's code. UEFI is terrible. Baseband firmwares are terrible. Security processor firmwares are terrible. AMT is terrible. Okay, but we still need them.

harshreality··on Entropic Engineering DEFCON 32 Statement
DEFCON isn't the entity doing the work. It's up to EE to get DC's clear agreement on changes of terms. Otherwise, EE must either:

a) acknowledge that they can't fulfill the contract under the existing terms, and follow the contract's termination procedures

b) keep working to try to complete the project, because the agreed upon payment is better, even considering the extra work, than whatever contract termination involved

When DC told EE to stop work, they did so rather than say "everything's fine, we're continuing as agreed"? That means they knew they couldn't deliver as contracted, or didn't want to because every day they kept working would lose them more money even if they fulfilled the contract.

This is why they should've had a reasonable contract that didn't require heroics in order to break even. Because, when things started to go bad, they needed a fallback besides taking a big loss for partial work, and taking a bigger loss for complete work.

Or alternatively, they could've reasonably contracted to do something nearly impossible, if they were okay with failing and getting nothing, at least for the r&d portion, turning it into an RP2350 learning opportunity. (Presumably, if they made it to production, the contract easily covered production costs.)

harshreality··on Entropic Engineering DEFCON 32 Statement
Exactly. Let's see the formal contract. The deliverables, the payment schedule, and any emails indicating DC agreement to subsequent requests for changes of terms.

The way EE phrases it, they were paid much less than they were owed, but owed according to what? Their internal accounting, or what they'd mutually agreed on with DC? Only the latter matters.

Emails saying "it's going to cost $X more", if any of EE's emails rose to that level of clarity and directness, are legally useless and meaningless without clear assent from DC.

A water kettle lets you consistently heat water to the same temperature (not just boiling, high-end kettles have additional temperature options), regardless of:

- Initial temperature of water

- Position of water container

They also prevent superheated water accidents.

harshreality··on An Interview with Robert Caro and Kurt Vonnegut (1999)
https://www.nytimes.com/interactive/2020/04/01/business/coro...

Guns per person has gone up significantly. A wild guess might be 20-40%, but exact estimates are difficult. Sales are tracked and have gone way up, which is the starting point for estimating change in guns per person, but difficulty in estimating and combining all the factors makes it difficult to integrate.

(Most states don't track ownership, background checks aren't 1:1 with guns, gun purchase stats depending on how they're reported might include used guns, guns manufactured aren't necessarily going to civilians, and of course some guns are permanently lost or destroyed, or taken out of the country.)

harshreality··on Intel confirms no recall for Raptor Lake CPUs,microcode won't fix affected units
Other than the chips that are significantly damaged prior to the updated microcode, why should this be treated differently from the meltdown saga? Fixes for that required significant slowdowns, except in niche applications with trustworthy code or air-gapped systems such that the vulnerability could be ignored. No Recall. Class actions ongoing, but everyone's mostly forgotten about them.

More conservative voltages will only lead to small (low single-digit) performance decreases, right? Isn't that less significant a performance hit than meltdown countermeasures? The only way I can imagine performance really tanking would be if Intel has to severely down-rate supported memory speeds as well, if the ring bus can't handle higher memory speeds at slightly reduced voltages.

harshreality··on Intel confirms no recall for Raptor Lake CPUs,microcode won't fix affected units
Is there any RUMINT about specifically why it's delayed? The delay itself is not RUMINT, and it's obviously some QA issue, but beyond that?

The only rumors I've seen are generic guesses: something AMD wasn't screening for, maybe coincidence, or maybe detected after the Intel mess sent AMD's QA teams scurrying to make sure they don't have any similar issues.

It could even be a combined issue with 3rd-party motherboards with AMD's new chipsets, the combination of which they wouldn't have been able to thoroughly test much earlier.

Isn't RUMINT on the Intel problem that, even though it's nominally a chip problem, it may occur primarily due to motherboards not following guidance? For instance, if a spec says the chip and mobo should lower max voltage by 100mV under certain conditions, but the chip still sometimes requests the full original voltage under those conditions, and the mobo provides it, whose fault is that? Maybe not exclusively Intel's, depending on how the specs are documented (a classic should vs must issue).

It seems likely that small process sizes and pushing the limits of performance are going to cause more problems like this Intel one. Notice Intel didn't have this problem before they had to push their chips to compete against the high-end Ryzens.

harshreality··on Google Drive scans files for copyright infringement
This (the copyright scanning policy) isn't new, is it?

What it's scanning for in this case is material it believes to be copyrighted, and restricts features (notably sharing) for content that matches.

Given that copyright law exists, and that Google doesn't like wasting engineering time on legal stuff unless refusing to do it would result in lawsuits, this scanning policy is a fairly low-impact solution that has probably been deemed legally necessary to avoid media company lawsuits. I don't like it, but the alternative is for Google (and Microsoft, and any other cloud storage that allows sharing) to mount an expensive legal effort to try to overturn decades of digital copyright precedent, which is likely to fail.

harshreality··on Tom Waits vs. Frito-Lay, Inc (2003)
The funniest thing about the whole affair is that it wouldn't have blown up except for psychological priming. And some people are so blind to this effect that they've formed what's effectively an army on these OpenAI-ScarJo threads.

First, the "Her" reference from OpenAI.

Then ScarJo saying "Hey that sounds like me. Even some of my friends think so."

The voices sound kind of similar in some ways, and dissimilar in other ways. If the voice actor was trying to mimic ScarJo, she didn't do a very good job.

Is a casual reference to the title character exemplifying the same concept, a female-voiced AI, in a movie that won best screenplay at the Academy Awards and Golden Globes, an IP violation? Even if that were the case, it would be a studio matter and not Scarlett's IP.

I am curious why they reached out to ScarJo again 2 days prior, though.

Did they want to use her purely for marketing? That seems doubtful, because they'd have to get movie studio clearance to use "Her" in official marketing.

Did they have a separate model trained on her voice (I wouldn't put this past OpenAI) and were hoping they could get last-minute clearance to use it? This is actually my suspicion. That failed, so they just went with the voice models they already had clearance to use. That's not illegal. It's not even unethical. Anyone can try to train voice models on voice samples they collect. What's a problem is commercial use and representation of likeness.

I don't think a casual reference to Her was a representation that the voice is like ScarJo. It was merely referencing (very effectively) the concept of the movie's always-there [female] AI-voiced AI-chatbot.
