Should you flush with toilet lid up or down? Study says it doesn’t matter

Pardon us while we go stock up on toilet tank disinfectant dispensers.

Whether the toilet lid is up or down doesn't make much difference in the spread of airborne bacterial and viral particles.

File this one under "Studies We Wish Had Let Us Remain Ignorant." Scientists at the University of Arizona decided to investigate whether closing the toilet lid before flushing reduces cross-contamination of bathroom surfaces by airborne bacterial and viral particles via "toilet plumes." The bad news is that putting a lid on it doesn't result in any substantial reduction in contamination, according to their recent paper published in the American Journal of Infection Control. The good news: Adding a disinfectant to the toilet bowl before flushing and using disinfectant dispensers in the tank significantly reduce cross-contamination.

Regarding toilet plumes, we're not just talking about large water droplets that splatter when a toilet is flushed. Even smaller droplets can form and be spread into the surrounding air, potentially carrying bacteria like E. coli or a virus (e.g., norovirus) if an infected person has previously used said toilet. Pathogens can linger in the bowl even after repeated flushes, just waiting for their chance to launch into the air and spread disease. That's because larger droplets, in particular, can settle on surfaces before they dry, while smaller ones travel further on natural air currents.

The first experiments examining whether toilet plumes contained contaminated particles were done in the 1950s, and the notion that disease could be spread this way was popularized in a 1975 study. In 2022, physicists and engineers at the University of Colorado, Boulder, managed to visualize toilet plumes of tiny airborne particles ejected from toilets during a flush using a combination of green lasers and cameras. It made for some pretty vivid video footage:

Chinese malware removed from SOHO routers after FBI issues covert commands

Routers were being used to conceal attacks on critical infrastructure.

The US Justice Department said Wednesday that the FBI surreptitiously sent commands to hundreds of infected small office and home office routers to remove malware China state-sponsored hackers were using to wage attacks on critical infrastructure.

The routers—mainly Cisco and Netgear devices that had reached their end of life—were infected with what’s known as KV Botnet malware, Justice Department officials said. Chinese hackers from a group tracked as Volt Typhoon used the malware to wrangle the routers into a network they could control. Traffic passing between the hackers and the compromised devices was encrypted using a VPN module KV Botnet installed. From there, the campaign operators connected to the networks of US critical infrastructure organizations to establish posts that could be used in future cyberattacks. The arrangement caused traffic to appear as originating from US IP addresses with trustworthy reputations rather than suspicious regions in China.

Seizing infected devices

Before the takedown could be conducted legally, FBI agents had to receive authority—technically for what’s called a seizure of infected routers or "target devices"—from a federal judge. An initial affidavit seeking authority was filed in US federal court in Houston in December. Subsequent requests have been filed since then.

Sometimes, it's worth taking a moment to note the end of an era, even when that ending might have happened a long time ago. Today, Apple announced that it considers the mid-2012 13-inch MacBook Pro obsolete. It was the last MacBook Pro to include an optical drive for playing CDs or DVDs.

This means that any MacBook Pro with an optical drive is no longer supported.

Regarding products deemed obsolete, Apple's support page on the topic says:

On Tuesday, OpenAI announced a new feature in ChatGPT that allows users to pull custom personalities called "GPTs" into any ChatGPT conversation with the @ symbol. It allows a level of quasi-teamwork within ChatGPT among expert roles that was previously impractical, making collaborating with a team of AI agents within OpenAI's platform one step closer to reality.

"You can now bring GPTs into any conversation in ChatGPT - simply type @ and select the GPT," wrote OpenAI on the social media network X. "This allows you to add relevant GPTs with the full context of the conversation."

OpenAI introduced GPTs in November as a way to create custom personalities or roles for ChatGPT to play. For example, users can build their own GPTs to focus on certain topics or certain skills. Paid ChatGPT subscribers can also freely download a host of GPTs developed by other ChatGPT users through the GPT Store.

Cops bogged down by flood of fake AI child sex images, report says

Investigations tied to harmful AI sex images will grow “exponentially,” experts say.

Law enforcement is continuing to warn that a "flood" of AI-generated fake child sex images is making it harder to investigate real crimes against abused children, The New York Times reported.

Last year, after researchers uncovered thousands of realistic but fake AI child sex images online, quickly every attorney general across the US called on Congress to set up a committee to squash the problem. But so far, Congress has moved slowly, while only a few states have specifically banned AI-generated non-consensual intimate imagery. Meanwhile, law enforcement continues to struggle with figuring out how to confront bad actors found to be creating and sharing images that, for now, largely exist in a legal gray zone.

“Creating sexually explicit images of children through the use of artificial intelligence is a particularly heinous form of online exploitation,” Steve Grocki, the chief of the Justice Department’s child exploitation and obscenity section, told The Times. Experts told The Washington Post in 2023 that risks of realistic but fake images spreading included normalizing child sexual exploitation, luring more children into harm's way, and making it harder for law enforcement to find actual children being harmed.

ISP Suggests That Record Labels Can Sue Torrent Client Developers

Internet provider Grande Communications hopes to overturn a jury verdict that awarded $47 million in piracy damages to several record labels. The company argues that merely providing Internet services to pirates should not invoke liability. Others, including BitTorrent client developers and torrent site operators, are more directly related to piracy activity, the ISP notes.

From: TF, for the latest news on copyright battles, piracy and more.

justiceLate 2022, several of the world’s largest music companies including Warner Bros. and Sony Music prevailed in their lawsuit against Internet provider Grande Communications.

The record labels accused the Astound-owned ISP of not doing enough following complaints about pirating subscribers. Specifically, the labels alleged that the company failed to terminate repeat infringers.

The trial lasted more than two weeks and ended in a resounding victory for the labels. A Texas federal jury found Grande guilty of willful contributory copyright infringement, and the ISP was ordered to pay $47 million in damages to the record labels.

$47 Million Appeal

Last September, Grande filed its opening brief in which it again argued that the lower court reached the wrong conclusion. Internet providers shouldn’t be held liable for pirating customers based on third-party allegations, the company noted.

Among other things, the ISP believes that it shouldn’t have to terminate Internet access so easily. This view was supported by several telecom industry groups, who all object to disconnecting subscribers’ internet access based on copyright claims.

The record labels countered the appeal, arguing that the jury’s verdict should be upheld. Any other outcome would make it almost impossible to tackle the online piracy problem.

The labels explained that ISPs play a central role in BitTorrent-based piracy, as they are the only ones who can link an IP-address to a subscriber. This means that when rightsholders or their anti-piracy partners sent infringement notifications to Grande, the ISP was the only party that could address this conduct.

Grande Responds to Labels

This week, Grande submitted a reply brief in which it counters the music companies’ arguments. The ISP maintains that it shouldn’t be held liable for pirating subscribers, citing last year’s ‘Twitter vs. Taamneh‘ Supreme Court ruling.

The U.S. Supreme Court held that social media platforms aren’t liable for ISIS terrorists who used their services to recruit and raise funds. In a similar vein, Grande believes that it shouldn’t be held liable for subscribers who pirate content.

The record labels previously argued that the Supreme Court ruling shouldn’t be directly translated into a copyright context. That would essentially change the concept of contributory copyright infringement based on a case that has nothing to do with copyright, they reasoned.

Understandably, Grande believes that the Supreme Court decision is directly relevant and quite essential.

“The central contributory copyright infringement issue before the Court is whether providing internet service to a direct copyright infringer, standing alone, is sufficient to support contributory liability. The Supreme Court recently made clear that it is not,” the ISP writes.

Grande cites the Supreme Court, which concluded that it would “run roughshod over the typical limits on tort liability” to “effectively hold any sort of communication provider liable for any sort of wrongdoing merely for knowing that the wrongdoers were using its services and failing to stop them.”

“Dramatic Expansion of Copyright Liability”

The ISP notes that the record labels are essentially asking the Court to authorize a dramatic expansion of secondary copyright infringement liability. This means that if an ISP fails to take “simple measures” to stop piracy, it becomes responsible for the activity.

However, if the court of appeals relies on the recent Supreme Court ruling, Grande should not be held liable. This leaves the court with two options, Grande says.

(1) Follow the Supreme Court’s precedents on the proper scope of secondary liability for copyright infringement (as Grande argues)

(2) Deem those precedents inapplicable and instead expand contributory liability (as the district court did) by adopting the Ninth Circuit’s “simple measures”

In its attempt to avoid liability, Grande explicitly points a finger at other parties in the BitTorrent ecosystem, while also highlighting that rightsholders have the option to sue pirates directly.

Suing Pirates, Torrent Sites, or Torrent Client Devs

The record labels previously argued that it’s important to hold ISPs liable because they are the only party that can match IP addresses to individual subscribers; Grande doesn’t deny that. Instead, it points out that rightsholders can use the information to sue pirates directly.

“They can file a John Doe lawsuit against an alleged infringer known only by IP address and then serve a subpoena on the ISP to obtain their identity,” Grande explains.

The Supreme Court rejected the claim that Twitter and others aided and abetted terrorist activity because it didn’t “consciously and culpably” participate in the illegal activity. According to Grande, Internet providers are even further distanced from any wrongdoing.

Another option would be to go after the operators of torrent sites or the developers of BitTorrent clients, the ISP adds.

“The Labels can also pursue claims against people who actually induce and encourage BitTorrent file sharing, like the creators and distributors of BitTorrent software and the operators of BitTorrent websites,” Grande writes.

“That it may be easier for the Labels to sue Grande is not a legitimate basis for expanding the scope of common law contributory liability.”

torrent client dev

Grande doesn’t explain why or when developers of torrent clients should be held liable for piracy. Popular torrent clients and sites that distribute this software are typically content-neutral and don’t actively encourage piracy. That is similar to the defense Grande relies on.

“ISPs that actively encourage infringement — for example, by instructing customers on how to engage in piracy — would be contributorily liable. ISPs that merely provide content-neutral internet access to their subscribers would not.”

Material Contribution

The ISP adds that it did not materially contribute to any copyright infringement. Instead, it argues that its actions remained distanced from any piracy activity.

“Grande neither ‘facilitated’ nor ‘provided tools for’ copyright infringement, however one might understand those terms. The only affirmative thing Grande did was provide content-neutral internet service to all its customers”

The reply again brings up the suggestion that there are many other actors who, unlike Grande, directly enable BitTorrent file-sharing. In addition to mentioning torrent client developers, BitTorrent inventor Bram Cohen, tracker operators, and hosting providers all get a mention.

piratesuggest

“Each of these actors plays a direct role in the sharing of copyrighted music files over BitTorrent. Grande, in contrast, stands far removed from the infringing conduct,” Grande writes.

Going Forward

We assume that many of the mentioned parties will entirely disagree with the insinuation that they could be liable for piracy. Similarly, the record labels will have a different outlook on the matter as well, as will become clear as the case progresses.

The above is just a small selection of the arguments and counterpoints presented in the 70-page reply brief. Among other things, it also reiterates that would be a “draconian overreaction” to terminate Internet connections because someone in a household may be pirating.

What’s clear, however, is that the stakes are high in this case. Not just for the $47 million that’s on the line here, but also for other ISPs and their subscribers.

A copy of Grande’s reply brief, filed at the U.S. Court of Appeals for the Fifth Circuit, is available here (pdf).

Comcast reluctantly agrees to stop its misleading “10G Network” claims

Comcast said it will drop “Xfinity 10G Network” brand name after losing appeal.

Comcast has reluctantly agreed to discontinue its "Xfinity 10G Network" brand name after losing an appeal of a ruling that found the marketing term was misleading. It will keep using the term 10G in other ways, however.

Verizon and T-Mobile both challenged Comcast's advertising of 10G, a term used by cable companies since it was unveiled in January 2019 by industry lobby group NCTA-The Internet & Television Association. We wrote in 2019 that the cable industry's 10G marketing was likely to confuse consumers and seemed to be a way of countering 5G hype generated by wireless companies.

10G doesn't refer to the 10th generation of a technology. It is a reference to potential 10Gbps broadband connections, which would be much faster than the actual speeds on standard cable networks today.

Google earnings: 100 million Google One subscribers, Google Cloud profits

We highlight the interesting numbers from Google’s earnings call.

Alphabet's earnings call was yesterday, and as usual, the company took in a lot of money ($86.31 billion), thanks mostly to ad click-through rates being at a certain level. More interesting, though, are the product numbers tucked away in the report.

For the good news, a big announcement was the success of one of Google's biggest subscription plans, Google One, which CEO Sundar Pichai said is "just about to cross 100 million subscribers." Google One is mostly a cloud-storage plan for Google accounts, allowing users to pay a monthly fee to get more than the 15GB of Drive and Gmail storage that comes free with a Google account. Pichai says the company's whole subscription business—which is going to be Google One (storage), Google Workspace (business accounts), YouTube Premium (ad-free YouTube), and YouTube TV (a cable TV alternative)—are up to $5 billion in annual revenue. That's up fivefold since 2019.

Speaking of subscriptions, one of Google's most expensive, the $350-a-year NFL Sunday Ticket, didn't have any hard numbers associated with it. Google SVP and CBO Philipp Schindler said the company was "pleased with the NFL Sunday Ticket signups in our first season." Sunday Ticket was always a money-loser for DirecTV, and that was before the price shot up half a billion in the streaming era. Google is now reportedly on the hook to pay the NFL $2 billion a year for the next seven years. When asked about a return on investment for the project, Schindler only cited "solid" advertiser interest and that "NFL Sunday Ticket supports our long-term strategy and really helps solidify YouTube’s position as a must-have app on everyone’s TV set."
