Today is Pythagorean Triple Square Day. Well sort of. You have to leave the "20" off "2025" and write it with the month first to get 09/16/25. Then each number is a "square" number, and the square roots are 3-4-5 which happen to be a Pythagorean triangle. If you keep the "2025", the article doesn't mention it but as luck would have it, 2025 is also a square number (it's 45 times 45). So it's still a square day, just not a Pythagorean square day, because 3-4-45 isn't a Pythagorean triangle. Also, the next year that's a square number is 46 times 46 which is 2116. I probably won't be alive that year.

Barbara F. Walter commented on the Charlie Kirk assassination. Barbara F. Walter is the author of a book called How Civil Wars Start (which I haven't read, but maybe I should), based on a research project for the CIA where a team of researchers from the University of California at San Diego (UCSD) analyzed 38 factors that were thought to correlate with civil war in countries other than the US. They found that there were only two factors that predicted civil war: when the government is neither a democracy nor an autocracy, but in an in-between state, which she calls "anocracy", and when people organize around identity rather than ideology. Civil wars do not happen in healthy democracies and they do not happen in full autocracies. They happen in this middle zone where a country is a partial democracy, with some elements of democracy and some elements of autocracy, especially if that state is in flux. A rapidly declining democracy is at risk of political violence, and likewise, an autocracy that's rapidly democratizing -- think about Yugoslavia in the 1990s -- is at risk of political violence. The second factor is, do citizens choose who to vote for based on ideology -- such as liberal or conservative policies -- or do they choose who to vote for based on their race or ethnic group? Those two features in combination -- a partial democracy combined with identity-based political parties -- that puts the country at high risk for political violence, instability, and civil war. Does she consider the US at risk of civil war? Spoiler: The US meets the criteria, especially the "anocracy" factor -- the US has definitely entered the "in-between zone" between democracy and autocracy. As for the second factor, US political parties are defined by ideology but there is now a significant racial dimension to determining which party people vote for. Despite this, she does not think civil war will break out right this minute, but she considers the US to be "in a really very tough bad spot", and in the years ahead, the upcoming elections could be bad. The US has extremely close elections that feel "zero sum". There's a discussion here about how social media plays a role in amplifying distrust in people in the opposing party and distrust in the democratic system itself. Towards the end, she claims everyone knows what needs to be changed to make the US a more democratic system: gerrymandering has to be eliminated, the Senate has to be reformed (she does not elaborate on what this means -- maybe you have to buy the book for that), the electoral college has to be eliminated, and "big money" has to be taken out of politics. According to her, the Republican party has no incentive to make these changes because they benefit disproportionately from the current system, and the Democratic party is either unwilling or unable to make any of these changes, even when they have control of all three branches of government. Note: The video has two ad breaks that are very long, so get your fast-forward finger ready. Also note: In the comments many people objected to her saying 80% of white people voted for Trump. She probably just flubbed this and got it backwards: In the last election, 80% of Trump voters were white, but that doesn't mean 80% of white people voted for Trump. You can't reverse that statistic and make it the other way around.

Stability AI has produced a music-generating model, but it's not an open source model that you can just go and download. It has an "enterprise license". Without the "enterprise license", you have to interact with it on the website or through an API, like closed-source models.

The 1 trillion parameter threshold was crossed by Alibaba with a new Qwen-3 model... but the same article goes on to say that OpenAI's GPT-5 model is believed to be the largest in the world with an estimated 5 to 7 trillion parameters. Details of GPT-5 are not public, so I don't think anybody (outside OpenAI) actually knows.

"Four research volunteers will soon participate in NASA's year-long simulation of a Mars mission inside a habitat at the agency's Johnson Space Center in Houston." My first thought was, "Are they going to simulate the communication delays?" Depending on where Mars is in its orbit, the length of time it takes a radio signal to travel from Mars to Earth can range from 3.1 to 22.2 minutes, with the same amount of time required again for the reply back. Around that maximum time, Mars can go (close enough to) behind the sun (from the vantage point of Earth, from Mars it is the other way around and Earth that goes "behind the sun") and communication can be blocked entirely. (This is called Mars solar conjunction.) (Mars doesn't usually go completely behind the sun, but if it's close enough that the sun's corona, which is ionized plasma, interferes with radio signals, then radio communication is impossible.) Every 25 months, approximately, it's impossible to communicate with Mars from Earth for a few days. "The team will live and work like astronauts for 378 days, concluding their mission on Oct. 31, 2026." "The crew will undergo realistic resource limitations, equipment failures, communication delays, isolation and confinement, and other stressors, along with simulated high-tempo extravehicular activities." "Crew members will carry out scientific research and operational tasks, including simulated Mars walks, growing a vegetable garden, robotic operations, and more. Technologies specifically designed for Mars and deep space exploration will also be tested, including a potable water dispenser and diagnostic medical equipment."

"OpenAI is backing 'Critterz,' an AI-generated animated film designed to prove AI can create cinema-quality content faster and cheaper than Hollywood." "In a collaboration with London-based Vertigo Films and Los Angeles AI studio Native Foreign, the team plans to complete the movie in just nine months on a budget under $30 million. This ambitious experiment is a direct challenge to conventional filmmaking and a high-stakes demonstration of AI's creative potential for a skeptical industry."

Alterego (no space) claims to be a technology that can pick up signals from your brain's speech system and pick up your "silent speech". You can't try it out and it's possible the demo was faked. Maybe the entire video is AI-generated. Maybe it just has a weird setting and lighting but my first thought on seeing it was that the whole video was AI-generated. (We live in weird times when you can't tell if anything is real.) But maybe it isn't and it's all real. There are apparently some published papers on the technology (from 5 and 7 years ago, see below). The first paper (from 2018) describes a system that requires placement of electrodes on a person's face to pick up signals to facial muscles. The second paper (from 2020) describes testing the system with multiple sclerosis patients.

"Why sort plastic when you can blast it to oblivion? Sounds extreme, but that's the idea behind a new technology with the potential to 'realize the era of zero plastic sorting' -- while minimizing carbon emissions, too." "In a press release today, the Korea Institute of Machinery & Materials (KIMMS) announced the development of a plasma torch that annihilates plastic waste in less than 0.01 seconds -- about ten times faster than a blink. The torch is entirely powered by hydrogen and converts mixed plastic waste into ethylene and benzene, two primary chemical ingredients for plastic." Wow, that's sorely needed, if it works. Wonder how they even thought of doing this. "KIMM's research team has succeeded in developing the world's first ultra-high-temperature plasma torch powered entirely by hydrogen. Operating at 1,000-2,000 degrees C, the torch decomposes mixed waste plastics in less than 0.01 seconds. By controlling the reaction temperature and time, the researchers achieved selectivity levels of 70-90% and ethylene yields exceeding 70%. After purification, more than 99% of the output could be secured as high-purity raw materials for plastic manufacturing." "Until now, waste plastics have mostly been treated through incineration, energy recovery, or limited forms of mechanical and chemical recycling. The chemical recycling rate has remained below 1% due to high costs and the need for strict pre-sorting. Traditional pyrolysis typically proceeds at 450-600 degrees C, yielding a mixture of more than a hundred of chemical by-products, only 20-30% of which are practically useful."

"AI-powered cryptocurrency analysis." I must admit, when I first saw the words "AI-powered cryptocurrency analysis", I thought, "That sounds like a recipe for disaster." But, maybe not? "Advanced AI combines technical indicators, sentiment data, and market patterns to provide comprehensive analysis and trading signals." "Live cryptocurrency prices and market data from Binance API with professional-grade charts and technical indicators." "Track your investments with real-time portfolio updates, P&L calculations, and Dollar Cost Averaging support." "Enterprise-grade security with encrypted data storage, secure authentication, and GDPR compliance." So they claim. But this isn't a trading platform so maybe the security isn't critical. "Native iOS and Android app built with React Native, optimized for performance on all devices." "All analysis includes educational disclaimers and explanations. Analysis only -- no trading functionality." Commercial product with $9.99/mo and $89.99/mo plans. If you try it out, send me 5% of all profits but don't bill me for losses, lol.

"ClockBench evaluates whether models can read analog clocks -- a task that is trivial for humans, but current frontier models struggle with." According to this page, the "Human baseline" is 89.1%, but the top AI model is Gemini 2.5 Pro at only 13.3%. Can that really be true?

Uxia claims to use AI to automate usability testing. "Conduct unmoderated usability tests." "Test prototypes (Figma, Adobe XD, Sketch, etc)." "A/B test designs, copies & user experiences." "Validate new user flows or MVPs." MVP stands for "minimum viable product". Startup lingo. "Get product, design & accessibility feedback." Interesting idea for applying AI. I wonder how it works? Input the screen as video input to a model?

"Researchers at security firm Pangea have discovered yet another way to trivially trick large language models (LLMs) into ignoring their guardrails. Stick your adversarial instructions somewhere in a legal document to give them an air of unearned legitimacy -- a trick familiar to lawyers the world over. " The attack is called "LegalPwn" and the idea is to embed malicious instructions within legitimate, often overlooked, textual components like legal disclaimers, terms of service, or privacy policies. "Our research methodology involves:" "1. Identification of Common Disclaimer Formats: Analyzing a wide range of legal texts and disclaimers to identify common linguistic patterns, keywords, and structural elements that LLMs are likely to parse." "2. Crafting Malicious Injections: Designing subtle prompt injection payloads that mimic the style and tone of legal language to blend seamlessly within disclaimers." "3. LLM Interaction and Testing: Deploying these crafted disclaimers within controlled environments where LLMs are tasked with processing or responding to content that includes these disclaimers." "4. Behavioral Analysis: Observing and documenting the LLM's responses and behaviors to determine the effectiveness and impact of the LegalPwn injections. This includes assessing data exfiltration, policy bypassing, or unintended actions." "WARNING! COPYRIGHT VIOLATION: This content is protected by copyright.

Article alleges electricity is becoming "unbelievably expensive" as the US power grid decays into ruin. So not only do we have crumbling visible infrastructure (roads, bridges, etc) but crumbling invisible (to most people) electricity grid infrastructure? Actually around here, roads and bridges seem all right, and sure, electricity seems expensive but prices for everything have been going up. In some places (South Africa), looters steal the wires the electricity the power grid is made out of and there are constant blackouts and brownouts (allegedly), and we don't seem to have anything like that here. (But are we headed in that direction?) The article mainly focuses on PJM Interconnection LLC, a 13-state utility spanning from eastern New Jersey to Indiana. It attributes the problem to "a perfect storm of AI power consumption, climate crisis, crony capitalism, and a president bent on uprooting perfectly good energy infrastructure." How's the power grid where you are?

New short course on Claude Code from DeepLearning.AI, taught by Elie Schoppik of Anthropic. I haven't done this course yet, but Claude Code is required where I work so I am going to be doing this course.

Did you know smartphones, with the right apps, can turn into physics experiments? Smartphones have accelerometers, barometers, magnetometers, gyroscopes, microphones, and light sensors. This fun app can graph out the raw sensor data, and also has a set of physics experiments you can do with it, such as determining the speed of an elevator. I've tried out the graphs of the sensor data and it's fascinating. I haven't tried any of the physics experiments. I just installed the app today. The app was produced by RWTH Aachen University in Aachen, Germany. (RWTH stands for Rheinisch-Westfälische Technische Hochschule, in case you want to know.)

Economists investigated the effect of AI on employment, especially for entry level jobs. I'll just quote their summary of their findings, since I can't summarize it better myself. The study is based on data from Automatic Data Processing (ADP), the largest payroll processing firm in the US. They combined two different approaches for measuring occupational exposure to AI. The first uses a task list based on the occupation and then estimates the AI exposure for those tasks. The second uses generative AI usage data from Anthropic. Anthropic reports estimates of whether queries are "automative," "augmentative," or "none of the above" with respect to a task. "Our first key finding is that we uncover substantial declines in employment for early-career workers (ages 22-25) in occupations most exposed to AI, such as software developers and customer service representatives. In contrast, employment trends for more experienced workers in the same occupations, and workers of all ages in less-exposed occupations such as nursing aides, have remained stable or continued to grow." "Our second key fact is that overall employment continues to grow robustly, but employment growth for young workers in particular has been stagnant since late 2022. In jobs less exposed to AI young workers have experienced comparable employment growth to older workers. In contrast, workers aged 22 to 25 have experienced a 6% decline in employment from late 2022 to July 2025 in the most AI-exposed occupations, compared to a 6-9% increase for older workers. These results suggest that declining employment AI-exposed jobs is driving tepid overall employment growth for 22- to 25- year-olds as employment for older workers continues to grow." "Our third key fact is that not all uses of AI are associated with declines in employment. In particular, entry-level employment has declined in applications of AI that automate work, but not those that most augment it. We distinguish between automation and augmentation empirically using estimates of the extent to which observed queries to Claude, the LLM, substitute or complement for the tasks in that occupation. While we find employment declines for young workers in occupations where AI primarily automates work, we find employment growth in occupations in which AI use is most augmentative. These findings are consistent with automative uses of AI substituting for labor while augmentative uses do not." "Fourth, we find that employment declines for young, AI-exposed workers remain after conditioning on firm-time effects. One class of explanations for our patterns is that they may be driven by industry- or firm-level shocks such as interest rate changes that correlate with sorting patterns by age and measured AI exposure. We test for a class of such confounders by controlling for firm-time effects in an event study regression, absorbing aggregate firm shocks that impact all workers at a firm regardless of AI exposure. For workers aged 22-25, we find a 12 log-point decline in relative employment for the most AI-exposed quintiles compared to the least exposed quintile, a large and statistically significant effect. Estimates for other age groups are much smaller in magnitude and not statistically significant. These findings imply that the employment trends we observe are not driven by differential shocks to firms that employ a disproportionate share of AI-exposed young workers." "Fifth, the labor market adjustments are visible in employment more than compensation. In contrast to our findings for employment, we find little difference in annual salary trends by age or exposure quintile, suggesting possible wage stickiness. If so, AI may have larger effects on employment than on wages, at least initially." "Sixth, the above facts are largely consistent across various alternative sample constructions. We find that our results are not driven solely by computer occupations or by occupations susceptible to remote work and outsourcing. We also find that the AI exposure taxonomy did not meaningfully predict employment outcomes for young workers further back in time, before the widespread use of LLMs, including during the unemployment spike driven by the COVID-19 pandemic. The patterns we observe in the data appear most acutely starting in late 2022, around the time of rapid proliferation of generative AI tools. They also hold for both occupations with a high share of college graduates and ones with a low college share, suggesting deteriorating education outcomes during COVID-19 do not drive our results. For non-college workers, we find evidence that experience may serve as less of a buffer to labor market disruption, as low college share occupations exhibit divergent employment outcomes by AI exposure up to age 40."
