Verizon Wireless agreed to pay a $1,050,000 penalty to the US Treasury and implement a compliance plan because of a 911 outage in December 2022 that was caused by a botched update, the Federal Communications Commission announced today.

A consent decree explains that the outage was caused by "the reapplication of a known flawed security policy update file." During the outage, lasting one hour and 44 minutes, Verizon failed to deliver hundreds of 911 calls in Alabama, Florida, Georgia, North Carolina, South Carolina, and Tennessee, the FCC said.

"The [FCC] Enforcement Bureau takes any potential violations of the Commission's 911 rules extremely seriously. Sunny day outages, as occurred here, can be especially troubling because they occur when the public and 911 call centers least expect it," Bureau Chief Loyaan Egal said.

Gaming news site PCGamesN has a web tool, SteamIDFinder, that can do a neat trick. If you buy PC games on Steam and have your user profile set to make your gaming details public, you can enter your numeric user ID into it and see a bunch of stats. One set of stats is dedicated to the total value of the games listed as unplayed; you can share this page as an image linking to your "Pile of Shame," which includes the total "Value" of your Steam collection and unplayed games.

Using data from what it claims are the roughly 10 percent of 73 million Steam accounts in its database set to Public, PCGamesN extrapolates $1.9 billion in unplayed games, multiplies it by 10, and casually suggests that there are $19 billion in unplayed games hanging around. That is "more than the gross national product of Nicaragua, Niger, Chad, or Mauritius," the site notes.

That is a very loose “$19 billion”

"Multiply by 10" is already a pretty soft science, but the numbers are worth digging into further. For starters, SteamIDFinder is using the current sale price of every game in your unplayed library, as confirmed by looking at a half-dozen "Pile of Shame" profiles. An informal poll of Ars Technica coworkers and friends with notable Steam libraries suggests that games purchased at full price make up a tiny fraction of the games in our backlogs. Games acquired through package deals, like the Humble Bundle, or during one of Steam's annual or one-time sales, are a big part of most people's Steam catalogs, I'd reckon.

Late last week, both Bloomberg and The Washington Post published stories focused on the ostensibly disastrous impact artificial intelligence is having on the power grid and on efforts to collectively reduce our use of fossil fuels. The high-profile pieces lean heavily on recent projections from Goldman Sachs and the International Energy Agency (IEA) to cast AI's "insatiable" demand for energy as an almost apocalyptic threat to our power infrastructure. The Post piece even cites anonymous "some [people]" in reporting that "some worry whether there will be enough electricity to meet [the power demands] from any source."

Digging into the best available numbers and projections available, though, it's hard to see AI's current and near-future environmental impact in such a dire light. While generative AI models and tools can and will use a significant amount of energy, we shouldn't conflate AI energy usage with the larger and largely pre-existing energy usage of "data centers" as a whole. And just like any technology, whether that AI energy use is worthwhile depends largely on your wider opinion of the value of generative AI in the first place.

Not all data centers

While the headline focus of both Bloomberg and the Washington Post's recent pieces is on artificial intelligence, the actual numbers and projections cited in both pieces overwhelmingly focus on the energy used by Internet "data centers" as a whole. Long before generative AI became the current Silicon Valley buzzword, those data centers were already growing immensely in size and energy usage, powering everything from AWS web servers to online gaming services, Zoom video calls, and cloud storage and retrieval for billions of documents and photos, to name just a few of the more common uses.

Researchers at the Royal Melbourne Institute of Technology (RMIT) in Australia have developed special “energy-smart bricks” that can be made by mixing clay with glass waste and coal ash. These bricks can help mitigate the negative effects of traditional brick manufacturing, an energy-intensive process that requires large-scale clay mining, contributes heavily to CO₂ emissions, and generates a lot of air pollution.

According to the RMIT researchers, “Brick kilns worldwide consume 375 million tonnes (~340 million metric tons) of coal in combustion annually, which is equivalent to 675 million tonnes of CO₂ emission (~612 million metric tons).” This exceeds the combined annual carbon dioxide emissions of 130 million passenger vehicles in the US.

The energy-smart bricks rely on a material called RCF waste. It mostly contains fine pieces of glass (92 percent) left over from the recycling process, along with ceramic materials, plastic, paper, and ash. Most of this waste material generally ends up in landfills, where it can cause soil and water degradation. However, the study authors note, “The utilization of RCF waste in fired-clay bricks offers a potential solution to the increasing global waste crisis and reduces the burden on landfills."

During its T85 Titan flyby on July 24, 2012, the Cassini spacecraft registered an unexpectedly bright reflection on the surface of the lake Kivu Lacus. Its Visual and Infrared Mapping Spectrometer (VIMS) data was interpreted as a roughness on the methane-ethane lake, which could have been a sign of mudflats, surfacing bubbles, or waves.

“Our landscape evolution models show that the shorelines on Titan are most consistent with Earth lakes that have been eroded by waves,” says Rose Palermo, a coastal geomorphologist at St. Petersburg Coastal and Marine Science Center, who led the study investigating signatures of wave erosion on Titan. The evidence of waves is still inconclusive, but future crewed missions to Titan should probably pack some surfboards just in case.

Troubled seas

While waves have been considered the most plausible explanation for reflections visible in Cassini’s VIMS imagery for quite some time, other studies aimed to confirm their presence found no wave activity at all. “Other observations show that the liquid surfaces have been very still in the past, very flat,” Palermo says. “A possible explanation for this is at the time we were observing Titan, the winds were pretty low, so there weren’t many waves at that time. To confirm waves, we would need to have better resolution data,” she adds.

Microsoft may be hit with a massive fine in the European Union for "possibly abusively" bundling Teams with its Office 365 and Microsoft 365 software suites for businesses.

On Tuesday, the European Commission (EC) announced preliminary findings of an investigation into whether Microsoft's "suite-centric business model combining multiple types of software in a single offering" unfairly shut out rivals in the "software as a service" (SaaS) market.

"Since at least April 2019," the EC found, Microsoft's practice of "tying Teams with its core SaaS productivity applications" potentially restricted competition in the "market for communication and collaboration products."
