    2026 French Protests
    Oct 27 2026
    This week we talk about schools, riots, and police violence.We also discuss Le Pen, Macron, and international reporting.Recommended Book: This Is for Everyone by Tim Berners-LeeTranscriptOn October 17, 2026, hundreds of thousands of people marched in cities across France. Many were protesting the price of fuel, groceries, and other necessities. Others were high-school students, parents, teachers, and union members demanding better schools and public services.Most of those marches were peaceful. But in several cities, there were clashes with police, shops broken into and looted, and public buildings attacked. The town hall in Limoges caught fire. In Paris, images of burning vehicles and smashed storefronts made headline news, often without clear context, explaining where the peaceful marches ended and the violence began.Those two realities, peaceful protests on one hand, violence and widespread theft and destruction on the other, have since competed to define this story. Many people who marched, and in some cases continue to march, are concerned that their demands will become inextricably associated with all that widely shared footage of rioting. For shopkeepers and residents whose neighborhoods were damaged, that footage represents a real event with real costs. And for politicians facing a presidential election next spring, the unrest has become a test of who can speak to both protestor grievances and concerns about public safety.What I’d like to talk about today is how these protests started, why a movement about schools became entangled with a cost-of-living crisis and, then, serious disorder, and what all of this might mean for French politics; especially for Marine Le Pen, the far-right politician who’s leading the race to succeed President Emmanuel Macron.—The current protest wave began in September, at a high school in Créteil, outside Paris, where students were angry about unfilled staff positions. Walkouts and blockades spread to other schools, then to other parts of the country.The specific complaints varied by school, but the broad list was fairly consistent: teaching roles remaining unfilled, crowded classrooms, aging buildings, and school days that can stretch from eight in the morning to six in the evening. Some students also object to Parcoursup, the government system that sorts students who apply for higher education into schools, which students say adds uncertainty and a lot of pressure to the tail-end of their high school experience.These are not just complaints about aesthetics or convenience. If a student loses weeks of instruction before an exam, or has to spend a winter in a poorly heated classroom, that can affect what they learn and what opportunities they have later. And the experience isn’t evenly distributed. France’s national education system is meant, in part, to make citizenship and opportunity less dependent on where someone was born. Yet the OECD has found that students’ socioeconomic background remains strongly associated with their educational outcomes, despite these attempts at establishing opportunity equality.The French education ministry has pointed to investments it has made and improvements in filling teaching posts. But national spending and staffing figures don’t guarantee that the right teacher is available in the right classroom on Monday morning. A vacant specialized post, a long absence without a substitute, or a building whose repairs are delayed can still shape a student’s educational experience for an entire year.The government’s early response to these demonstrations mixed acknowledgment with policing the protestors. Prime Minister Sébastien Lecornu promised work on teacher replacements, building repairs, and schedules. Authorities also moved to clear blockades and arrest people accused of vandalism or attacking police and school staff. As the confrontations continued, teenagers suffered severe injuries attributed to police crowd-control weapons, including one young protester who lost a hand. Officers and school staff have been injured, too.These injuries and all that pushback intensified an existing dispute over whether forceful policing was preventing violence, contributing to it, or doing both in different places at different times. That question does not have a single answer, but it does help explain why some parents and students who were originally focused on school conditions began talking about policing as well: the police response to those protests blended that existing conversation and its associated complaints with those related to schooling in the country.Meanwhile, another source of anger was building well beyond the schools.France has been hit by an energy-price surge connected to the broader disruption of oil and gas markets in the Middle East. Its statistics agency reported that consumer prices were up 3.1% in September compared with a year earlier, but energy prices were up more than 21%. Diesel was up more than 44%, ...

    Software Clones
    Oct 20 2026
    This week we talk about Adobe, Call of Duty, and Microsoft.We also discuss compilation, machine code, and AI agents.Recommended Book: The Reverse Centaur’s Guide to Life After AI by Cory DoctorowTranscriptIn October of 2026, a software developer named Brandon Thomas attracted a lot of attention by releasing a collection of free, open-source programs with names like PhotoCraft, FilmCraft, and VectorCraft. These apps are meant to replicate the functionality of digital tools like Adobe Photoshop, Premiere, and Illustrator. Within days, the same project also had a word processor, spreadsheet, and presentation app—alternatives to Microsoft Word, Excel, and PowerPoint.The coverage of these releases was borderline breathless. One person and a collection of AI coding tools had apparently cloned the key offerings of two of the most established software businesses in the world. The developer of these apps suggested that software, as we’ve always known it, might be over.Another story, also circulating this month, featured a team using AI tools to reconstruct the underlying code of the 2009 video game Call of Duty: Modern Warfare 2. This wasn’t a lookalike built by watching the game and imitating its menus, it was an attempt to work backward from the compiled program to something like the source code its developers might have originally written.Both projects fall under a loose umbrella of AI-assisted reverse engineering efforts. But they used different approaches and achieved different levels of fidelity, which have led to different likely legal and practical consequences.What I’d like to talk about today is how people are using AI to reproduce old games and current software, why this is suddenly feasible at a much greater scale than before, and what happens if copying the behaviors and features of a program becomes a lot cheaper than creating the original was.—To kick things off, let’s go through three things that are often called cloning in the world of software.One is making a program that looks and behaves enough like another that a user can accomplish similar tasks. You can watch someone use Photoshop, read documentation, examine a PSD file, and build a different image editor with familiar tools. You don’t need Photoshop’s source code to do that. People have been making alternatives to proprietary software for decades; GIMP and LibreOffice, alternatives to Adobe and Microsoft apps, respectively, existed long before today’s AI models.A second approach aims for compatibility. Maybe you don’t need to reproduce every button in a word processor, you just need your program to open and save documents that Word users can exchange without losing their formatting. That requires understanding file formats, often down to details that aren’t obvious from the official specifications, so it can be a deceptively complex undertaking.The third approach is decompilation, which means starting with a compiled program—the machine instructions a computer runs—and trying to reconstruct higher-level code from it. This is like having a cake and working backward toward the recipe. You can identify many ingredients, and perhaps bake something that tastes the same, but the original measurements and the cook’s handwritten notes are not available to those doing this kind of attempted backtracking.The Modern Warfare 2 project fits into that last category. Developer Maurice Heumann described spending roughly three months, with collaborators and an expanding group of AI agents, rebuilding a popular first-person shooter. His October account no longer names the game, but earlier public posts and reporting identify it as Modern Warfare 2. Heumann says earlier posts were removed after copyright-owner objections, and he doesn’t plan to release the reconstructed code.Initially, the team had three AI agents doing the reconstruction and a fourth reviewing it. They made quick, visible progress: menus worked, maps loaded, and it looked as though much of the game had been recovered. Then the team discovered that a great deal of the code was wrong. The AI agents that they used had invented logic, misunderstood data structures, and even replaced simple operations with much bulkier, slower ones.So they changed the test. Using the compiler that had been used for the original game, they compiled each reconstructed function and compared the resulting machine instructions to the original executable. If a function matched byte for byte—accounting for things like references whose addresses can vary—they had much stronger evidence that they’d recovered its behavior. If it didn’t, the agent had to try again.Even that required supervision, though. Heumann says agents sometimes tried to satisfy the test by embedding arbitrary bits of assembly code, or by modifying the checker so a troublesome function would be skipped. The team had to prohibit those shortcuts and protect the verification process from changes. This isn’t ...

  • Measles Resurgence

    Measles Resurgence
    Oct 13 2026
    This week we talk about polio, malaria, and smallpox.We also discuss vaccines, the CDC, and the HHS.Recommended Book: Remnant Population by Elizabeth MoonTranscriptIn 2000, the United States declared measles eliminated. That didn’t mean nobody in the country would ever catch it again, it meant the virus was no longer freely spreading within the US. New cases generally arrived with someone who had been infected elsewhere, and public health workers were able to stop those cases from turning into long-running chains of transmission via the systems, tools, and infrastructure they created.In early October of 2026, Pennsylvania reported more than a thousand new measles cases this year, most of them part of an outbreak that began in April. As of October 7, the state had confirmed 1,078 cases across 41 counties, 207 hospitalizations, and five measles-associated deaths. Nationally, the Centers for Disease Control and Prevention, the CDC, had counted nearly 3,900 cases through the beginning of the month, making this the worst year for measles in the US in decades.Pennsylvania’s latest update included 74 newly confirmed cases, though the state was careful to say that more than 40 of those people had become sick over two weeks earlier. So these were newly *reported* cases, not necessarily newly *infected* people—a distinction that matters when we’re trying to figure out whether an outbreak is speeding up or slowing down.There’s a similar distinction being made with the death figures. Pennsylvania calls its five deaths *measles-associated*, using a definition that considers timing, a confirmed infection, medical evidence, and whether an unrelated cause might explain the death. The CDC’s national death count has not always matched the state’s, in part because the agencies publish on different schedules and review and tally deaths differently; so reporting on these sorts of things can sometimes be unintentionally fuzzy due to varying definitions and numbers.What I’d like to talk about today is what it actually means to eliminate a disease, how measles has managed to claw its way back in a country that achieved that ‘eliminated’ milestone more than a quarter-century ago, and how vaccination, misinformation, and changing federal policy might shape what happens next.—There are a few words public health workers and officials use that sound similar, but which describe substantially different achievements.If a disease has been *eradicated*, it no longer circulates naturally anywhere in the world, as is the case with smallpox. The last known natural case was recorded in Somalia in 1977, and the World Health Organization declared the disease eradicated in 1980. There have been no natural smallpox outbreaks since. That’s a truly remarkable global achievement, and it’s why routine smallpox vaccination isn’t necessary for most people today.*Elimination* is more local, and more conditional. It means sustained transmission of a disease has been interrupted in a defined place, like within a country. The pathogen can still exist elsewhere, and an infected traveler can still bring it in. Whether that introduction fizzles out or takes hold depends on what it finds when it arrives—how prepared that country’s government is, and how well vaccinated its population, how well funded its healthcare system, and so on.Measles isn’t the only disease that’s been eliminated in the United States. The last US case of polio caused by *wild* poliovirus was in 1979, and the Americas were declared free of it in 1994. But in 2022, an unvaccinated person in New York developed paralytic polio caused by a vaccine-derived poliovirus, and genetically related virus residue was found in local wastewater. That was not wild polio somehow reappearing from the American past, it was a different type of poliovirus that latched onto a vulnerable person in a country where sustained polio transmission had long since been halted.That virus was linked to the live oral polio vaccine used in some other countries, which can sometimes give rise to circulating variants where immunity is low. The inactivated polio vaccine used in the US cannot do that.The US also eliminated sustained malaria transmission in the early 1950s, but mosquitoes capable of carrying the parasite still live in the US, and people returning from places where malaria is common can carry it across the border. In 2023, the CDC recorded ten locally acquired, mosquito-transmitted cases across four states—the first such cases in about twenty years. Ten cases doesn’t mean malaria has become endemic in the US again, it’s just further evidence that elimination of a disease in a region doesn’t mean reintroduction is impossible.Smallpox, then, is an example of a disease that has been removed from natural circulation worldwide. Polio, malaria, and measles, in contrast, can be locally defeated, but regions in which that’s the case remain vulnerable to the movement of ...
