An anonymous reader quotes a report from Ars Technica: Comcast reportedly plans significant job cuts in its cable division as the firm continues to lose residential broadband and TV customers. Comcast lost 144,000 residential broadband customers in Q3 2026, up from a 91,000-customer loss in the same quarter a year ago, the company said in its earnings report today. Comcast historically capitalized on a lack of competition for high-speed wired broadband. But now it faces stronger competition from fixed wireless providers and from fiber providers in parts of its cable territory. "Fixed wireless remains aggressive and continues to take share, while fiber construction remains elevated, with pockets of irrational pricing and promotional activity," Comcast co-CEO Mike Cavanagh said today in an earnings call. Comcast CFO Jason Armstrong said "irrational pricing" from fiber operators includes $30 to $40 monthly broadband offers "in specific markets in the third quarter." He said $30 to $40 pricing is irrational because deploying fiber costs $1,500 or more per home, and is "getting more expensive with construction costs up as you get into more suburban and rural areas." "As we look at the return profile of that, to us, that is irrational competition," Armstrong said. While he didn't name any specific competitors, Verizon has been pitching FiOS fiber plans that start at $30 a month. Comcast's network is a mix of fiber and cable, and it offers fiber-to-the-home in only small portions of its cable territory. Armstrong said more Comcast customers are leaving when they face "pricing transitions," apparently referring to the price hikes customers get when promotional offers expire. "We've been refining our offers and retention strategies to better manage these transitions and strengthen customer retention," he said. Cavanagh said that "satellite is not yet a material factor" in the competition Comcast faces, but that Comcast is focused on "anticipating emerging forms of competition and positioning our business to respond as the market evolves."

Physicists at Northwestern University have successfully trapped a single positron for an entire month, allowing researchers to study its quantum properties with unprecedented precision. "Further investigations using the trap might reveal the secret of why the world around us is made of matter and not antimatter, when things could have presumably gone either way," reports Scientific American. From the report: Every normal particle of matter has an antimatter counterpart with equal mass but opposite charge. To build their trap, physicists started with atoms of sodium 22, a radioactive isotope with a half-life of about two and a half years. When one of these atoms decays, it emits a positron -- the antimatter counterpart of the electron. "The big challenge is to persuade these positrons to slow down and then capture them," says Gerald Gabrielse, a physicist at Northwestern University, who oversaw the project. The team reported its achievement on Wednesday in Physical Review Letters (PDF). The first step is to send the positrons through the crystal lattice of a sliver of cold tungsten. As the particles go pinballing through the material, they slow down and lose energy. "Every time they bang into something, there's a chance of annihilation, but it doesn't always happen," Gabrielse says. "If they make it to the end, they get popped out." Next, the physicists steer the positrons along a channel using electromagnetic fields. Eventually the particles end up in a vacuum, just three tenths of a degree Celsius above absolute zero, trapped by an electric field on top and bottom and a magnetic field on the sides. "If you want to hold on to antimatter, you have to hold it in a container without walls," Gabrielse says. This method allowed the researchers to isolate and study a solitary, lone positron for a monthâ"and could let them do so indefinitely. The researchers intend to use their trap to make precise measurements of the positron's magnetic moment -- basically the strength and orientation of its magnetic field. To do this, they must determine two things: the energy needed to flip the direction of the positron's spin and the energy needed to make it jump from its ground state to its first excited state. Using a similar trap setup, Gabrielse and his team have already measured the magnetic moment of an electron to a precision of one part in 10 trillion. Taking the equivalent measurement for a positron will allow them to make a crucial comparison. "We're looking to see if they have an exactly opposite magnetic moment," Gabrielse says. That's the prediction of the Standard Model of particle physics. If the two have different values, however, this could help explain why our universe is made of matter instead of antimatter.

For the first time, the UN has declared that exceeding the Paris Agreement's 1.5C warming limit is "imminent and unavoidable." "We are now saying this window has closed, but we can open it again by making the overshoot as brief as possible," UN Environment Program Executive Director Inger Andersen said on a call with reporters. "This is about how to find a way back as shortly and as quickly as possible with as limited an overshoot as possible." CNN reports: Past reports have examined the distance between countries' emissions reduction commitments and what it would take to limit global warming to 1.5 C above preindustrial levels. However, this year's report redefines the gap. Instead, it examines new emissions overshoot scenarios, and what it would take to limit peak warming to just 1.7 to 1.8 degrees C before bringing temperatures back down to 1.5 C through emissions cuts and the use of carbon removal technologies. The report makes clear that every additional fraction of a degree of warming above 1.5 C "raises the risk of irreversible changes including in ice sheets, permafrost carbon, ocean circulation, and coral systems, along with devastating human impacts." Each added fraction of a degree of warming can have an "immense" impact "as measured in terms of damage, cost and loss of lives," said climate scientist Michael Mann of the University of Pennsylvania. Mann was not involved in producing the UNEP report. According to the UNEP, which is based in Nairobi, the lowest overshoot scenario would keep peak warming to between 1.7 and 1.8 degrees C and return global average temperatures to at or below 1.5 C by 2100. However, to follow such a pathway, global greenhouse gas emissions would need to be slashed by far more than anything currently on the table at the upcoming COP31 talks. This would require an 18% cut by 2030, 45% by 2035, and 69% by 2040, relative to 2025 levels. Meeting this lowest-possible overshoot scenario would require a tripling of renewable electricity capacity by 2035, and dramatic cuts to fossil fuels, including the phaseout of coal by 2040, the report states. In addition, there would need to be a major scaling up of carbon removal technologies, which so far have not been proven to work at such a large scale. In stark contrast to these figures, the fulfillment of existing emissions reduction pledges would only yield a 5-to-8% emissions cut by 2030 and an 11-to-15% reduction by 2035, the report found. This would be associated with a peak warming of about 2.6 degrees C. If countries simply follow their current policies, then warming could reach a peak of about 2.8 C. That estimate has increased since last year, in part because of the withdrawal of the United States from the Paris Agreement and retraction of its emissions reduction commitments, the report states. Even the scenario that assumes countries meet their existing reduction commitments, and nations with net-zero pledges succeed in fulfilling them, still brings warming to a peak of 2.1 C.

Earlier this year, I needed to learn PowerShell scripting for one Windows-related project, and I have tried it out a few more times on Mac. It has quickly become one of my favorite tools for automation and scripting-taking on jobs that I would have otherwise tried to do with Node.js, Shortcuts, macOS Automator, or heaven forbid, Bash scripts. I get it now. PowerShell is great, even if you don't use it as your shell, and even if you're on Mac or Linux. ↫ Corbin Davenport I don't use the shell often enough on any of my main machines to have much of an idea about the strenghths and weaknesses of PowerShell compared to more traditional shells, but this is definitely not the first time I've heard a lot of praise for it from people otherwise knee-deep in the UNIX and traditional shell world. There really must be something to this, and since PowerShell is also available on Linux and macOS, it's pretty straightforward to give it a go without having to deal with Windows.

Earlier this year, Garmin closed its Connect API developer program because it was being flooded with "AI"-generated applications to the point it couldn't handle them anymore. What made it worse was that half of the applications were never actually used, not even once. It also didn't help that Garmin treated every single application to the program the same way, whether it was from a hobbyist just wanting access to their own data, to a massive corporation developing a popular service used by god knows how many people. Today, the company has relaunched the program, and it's been considerably overhauled. While hobbyist use of the API is going to be free - which is way better than it was before - once you hit a thousand users, you're going to have to start paying. Still, Garmin's shift here towards charging for API access will set a dangerous precedent for the industry. Especially for a company that bills itself as a (or the?) premium sports hardware provider. On the flip side, there's simply no ignoring the flood of mostly AI apps that take up resources at Garmin and elsewhere to support. Heck, my inbox is flooded with these apps daily requesting reviews. It sounds like when Garmin shut off access to the API last spring, they were seeing inbound API requests at a daily scale that they'd previously only seen over a period of weeks. Simply put, there's no good answer. ↫ Ray Maker at DC Rainmaker The excesses of the easy availability of "AI" code generation impacts the entire industry. At least one good thing has come out of this: hobbyists can now access the Connect API developer program much easier than before.

If you've ever written C (or c++) on a mac, you'll know that the so-called gcc is just clang in disguise. Most people (fairly) assume that this is just an alias, but this is not true! It's a binary! Now, what is this binary? I naively assumed that it would just be shelling out to clang but it turns out the answer is more interesting than that. ↫ juliethefoxcoon It's all smoke and mirrors.

Over the last few weeks, we have been doing research on the integration of our official distribution packages when installed on a target system. In this context we have been looking at the current uses of alpm-install-scriptlet(5) files and alpm-hooks(5) in around 120 package source repositories (alpm-source-repo(7)) to better understand the underlying functionality and use-cases these two integrations offer and target. In this article we are going to look at how these two systems work, how Arch Linux is currently using them and attempt to provide suggestions for when to use which.
