Sonos is still trying to figure out why everyone hates its app:
Sonos has responded to user feedback following a significant app revamp last year. The company’s chief innovation officer, Nick Millington, has been working on addressing issues and restoring features that were left out of the controversial app redesign. Sonos has focused on understanding and fixing technical problems and enhancing functionality based on user feedback. They have made some improvements, such as allowing users to snooze alarms again and check the battery of portable speakers. However, features like playlist editing and queuing an entire folder from a local music library are still in the works and expected in upcoming releases. The process has been slow, but Sonos remains committed to improving the app based on user input.
How to learn a language like a baby:
The text discusses the challenges and effective methods for adults learning a new language. It highlights that while adults have more life experience, children learn languages more easily. Babies begin learning language in the womb, focusing on rhythm and melody before understanding words. In contrast, adults typically start with written words, which can hinder their ability to grasp the language’s overall sound and rhythm.
A study involving Czech adults listening to Māori, a completely novel language, showed that adults can quickly pick up on the melodic and rhythmic patterns of a new language, similar to babies. However, reading alphabetic spellings while listening impeded their ability to tune into these patterns. This suggests that initial exposure to a new language should prioritize listening over reading.
The text also notes that traditional language teaching methods, which emphasize reading and writing early on, might not be the most effective for adult learners. Instead, an immersive listening approach could help adults achieve spoken proficiency more quickly. The research implies that adult language learners and educators should focus on auditory engagement with the language before introducing written components.
Collatzeral Damage: Bitwise and Proof Foolish - Dhole Moments:
The text discusses two main topics: the Collatz Conjecture and ARX cryptographic algorithms. The Collatz Conjecture is a simple yet unsolved mathematical problem involving a recursive function that halves even numbers and multiplies odd numbers by 3 then adds 1. Despite its simplicity, it has evaded proofs and general solutions for nearly a century. The conjecture states that repeating this operation will eventually reach 1 for all positive integers, but there are no concrete proofs for this.
The text also delves into the ARX cryptographic algorithms, which are used in various hash functions and stream ciphers. The ARX operations include rotation, addition, and eXclusive OR (XOR). The ChaCha algorithm, an improvement over Salsa20, is highlighted for its enhanced diffusion, making it less susceptible to cryptanalysis. Diffusion in ARX constructions is crucial for ensuring that the output remains indistinguishable from a random oracle.
The author also ties these concepts together by discussing how the Collatz Conjecture can be thought of as a Turing machine-like operation, and how carry propagation in addition makes it difficult to predict the behavior of the Collatz function without actually performing the calculations. The text suggests that the Collatz Conjecture might be as undecidable as the Halting Problem, implying that it could be inherently unsolvable with current mathematical tools.
Overall, the text provides an engaging exploration of the Collatz Conjecture and ARX cryptographic algorithms, highlighting their complexity and the challenges they pose to mathematicians and cryptographers.
Downtown Doug Brown » Apple’s long-lost hidden recovery partition from 1994 has been found:
The text is a detailed account of the author’s journey to uncover and preserve a hidden recovery partition on an old Apple Macintosh Performa 550 computer. The story begins with a blog post by Pierre Dandumont, which mentioned a special functionality in the Performa 550 that included a hidden partition for system recovery. The author, having owned a Performa 550 in the past, was intrigued and decided to investigate.
The hidden partition was designed to automatically restore the system if it detected a problem, using a miniature System Folder stored on the partition. However, the author found that the partition was empty when trying to recreate it using Apple’s restore CD. This led to a extensive search for a Performa 550 with its original hard drive, as the partition would be lost if the drive was reformatted.
After much effort, the author finally obtained a Conner hard drive from a Performa 550 that had never been reformatted. Using a clever trick to bypass a stuck read head, the author was able to image the drive and discovered that it indeed contained the hidden recovery partition with all the necessary files. The partition worked as described, allowing the system to boot and restore the main system folder when needed.
The author’s findings confirmed the existence of this obscure feature and highlighted the importance of preserving such historical software artifacts. The text also delves into technical details about the partition, the files it contains, and how the recovery process works. The author concludes by sharing a drive image with the recovery partition for others to study and experience, and by encouraging anyone with a Performa 550 and its original hard drive to come forward and help fill in the remaining blanks about this feature.
The good times in tech are over:
The text discusses the changing landscape for software engineers over the past decade, highlighting a shift from a pampered, high-growth environment to a more challenging, cost-conscious one. In the 2010s, low interest rates allowed tech companies to spend freely, hire aggressively, and prioritize user acquisition over profitability. This led to a culture where software engineers were highly valued and well-compensated.
However, the economic environment changed in 2023 with rising interest rates, forcing companies to focus on profitability and cut costs. This shift has led to layoffs, reduced perks, and a more competitive job market. The author argues that this change is primarily driven by economic factors, not COVID-19 or AI, and that companies are now more focused on executive priorities rather than engineer interests. Engineers who resist this shift may face personal and professional risks, including layoffs.
The author suggests that while the current environment is tougher, it is also more realistic. Engineers now need to align their work with company goals to provide value and ensure job security. The silver lining is that the job of software engineering has become clearer, with rewards tied directly to the value provided to the company.
Male octopus injects female with venom during sex to avoid being eaten:
The text discusses a unique reproductive behavior in blue-lined octopuses (Hapalochlaena fasciata), where males inject females with tetrodotoxin, a potent venom, during mating. This venom, typically used for defense and predation, paralyzes the female without killing her, allowing the male to mate safely and avoid being eaten by the larger female. The study, led by Wen-Sung Chung from the University of Queensland, reveals that male octopuses have evolved larger venom glands to overcome the females‘ resistance to the toxin. This adaptation is seen as an example of a co-evolutionary arms race between the sexes.

iTunes Artwork Finder by Ben Dodson:
The text discusses several tools developed by the author to help users find high-quality artwork for various types of media on Apple platforms. The main tool, initially designed to find artwork for TV shows using the iTunes Search API, has been expanded to include movies, iBooks, albums, and app icons. Users can search for artwork by media type and country, and the tool provides both standard and high-resolution artwork links. Additionally, the author has created a new tool specifically for Apple TV shows and movies, which supports the 16:9 aspect ratio and includes a variety of high-res imagery.
The author has also developed an Apple Shortcut that can fetch high-resolution artwork from Apple Music URLs, and a new tool for finding Apple Music playlists, albums, and stations with uncompressed and animated artwork. The text emphasizes that the artwork is sourced directly from iTunes, and therefore, media not available on iTunes will not be found using these tools. Developers interested in automating the process are encouraged to host the publicly available source code on their own servers.
The author invites users to sign up for a free newsletter for updates and early access to new projects, and expresses gratitude for the popularity and support of the tools.
The text discusses the challenges and solutions for treating elderly patients in emergency rooms (ERs), highlighting the work of a multidisciplinary geriatric ER team at St. Mary’s Hospital in Montreal. The main issues are hospital-associated deconditioning and delirium, which can severely impact elderly patients‘ health and independence. The ER environment, with its noise, disruptions, and lack of familiar surroundings, can exacerbate these problems.
The geriatric team at St. Mary’s is proactive in assessing and treating elderly patients to prevent these issues. They aim to reduce ER stays and avoid readmissions by ensuring patients receive proper follow-up care and support. The team consists of a nurse, physiotherapist, occupational therapist, social worker, and geriatricians who work together to create tailored care plans. For example, they helped an 84-year-old patient, Maria Pastore, by arranging follow-ups, providing a walker, and coordinating with her residence for ongoing care.
The text also mentions the increasing number of elderly patients in ERs and the need for more comprehensive geriatric care across Canada. The St. Mary’s pilot program has shown promising results, with patients spending less time in the ER and fewer being admitted. The success of this approach highlights the importance of specialized geriatric care in ERs to improve outcomes for elderly patients.
Sign in as anyone: Bypassing SAML SSO authentication with parser differentials:
The text discusses critical authentication bypass vulnerabilities (CVE-2025-25291 and CVE-2025-25292) found in the ruby-saml library, which is used for single sign-on (SSO) via SAML. These vulnerabilities allow attackers with a valid signature to log in as any user, effectively enabling account takeover. The issues stem from the library’s use of two different XML parsers, REXML and Nokogiri, which can be exploited due to differences in how they interpret XML (a parser differential).
The discovery process involved multiple stages, including identifying the use of two parsers, establishing how a parser differential could be exploited, finding an actual differential, and creating a full exploit. The vulnerabilities were discovered during a bug bounty program and affected other projects like GitLab. To mitigate these issues, users of ruby-saml are advised to update to version 1.18.0, and libraries that reference ruby-saml, such as omniauth-saml, should also be updated. The fundamental issue was the disconnect between the verification of the hash and the signature, which could be exploited via parser differentials. While checking for Nokogiri parsing errors can help, a more robust fix involves ensuring a direct connection between the hashed content, the hash, and the signature. The text concludes by emphasizing the importance of sponsorship for open-source software and the need for users to stay updated with the latest security patches.
Google Being Forced To Sell Chrome is Not Good for the Web:
The text discusses the debate surrounding Google’s monopolistic practices and the proposed solutions to address them. The author argues that Google’s monopoly is primarily due to its payment for default search engine placements on browsers and devices, as highlighted in the U.S. vs Google court case. The author suggests that a more direct solution would be to stop Google from paying for these default placements and instead allow users to choose their default search engine, similar to how Apple was forced to allow browser choice.
However, the Department of Justice has proposed a more complex solution: forcing Google to sell its Chrome browser. The author contends that this is a less effective solution because Chrome is uniquely valuable to Google and not to other potential buyers. Google’s investment in Chrome has benefited the web as a whole by advancing web standards and making the web more open and efficient.
The author warns that if Google is forced to sell Chrome, the new owner might not continue investing in the web standards in the same way, leading to stagnation in web development. This could incentivize operating system makers to pull developers toward proprietary systems, ultimately harming the open web ecosystem. The author also expresses concern for Mozilla, which could suffer if Google stops paying for default search engine placement, further weakening investments in the open web. In conclusion, the author advocates for addressing Google’s monopolistic practices without forcing the sale of Chrome, as this could have unintended negative consequences for the web.

PoliticHook - Congressional Trade Alerts:
The text discusses PoliticHook, a tool created by Mark Eslano out of personal frustration from missing out on significant gains in biotech stocks. Eslano, who is not a professional developer, built this tool in his spare time. It has yielded impressive results, such as a 12% gain from early investment in a stock bought by a Congress member. The tool helps users avoid missing out on potential gains. The tool is very popular and almost at the break-even point with only 7 more Gold users needed to sustain the passion project. The creator is inviting users to try it out for free, emphasizing the potential to catch the next big trade.
Transformers without Normalization - DynamicTanh:
The text discusses a novel approach to replacing normalization layers in Transformers with a simple technique called Dynamic Tanh (DyT). Traditional normalization layers, like Layer Norm or RMSNorm, are widely used in neural networks and are considered essential. However, the authors demonstrate that Transformers can achieve similar or better performance without these normalization layers by using DyT.
The DyT operation is defined as $$\mathrm{DyT}(\boldsymbol{x}) = \tanh(\alpha \boldsymbol{x})$$, and it is inspired by the observation that layer normalization in Transformers often produces tanh-like, S-shaped input-output mappings. This operation can be easily implemented in a few lines of PyTorch code. The key finding is that layer normalization in Transformers generates input-output mappings that resemble scaled tanh functions, especially in deeper layers.
The effectiveness of DyT is validated across a wide range of tasks and models, including vision, language, speech, and DNA sequence modeling. In every case, Transformers with DyT achieve similar or better performance than their normalized counterparts, challenging the conventional wisdom that normalization layers are indispensable. The authors also provide resources for further reading and implementation details.
The text discusses the release of CSM 1B, a conversational speech model developed by SesameAILabs. This model, known as CSM, generates RVQ audio codes from text and audio inputs using a Llama backbone and a smaller audio decoder that produces Mimi audio codes. The model has a fine-tuned variant that powers an interactive voice demo and a hosted HuggingFace space for testing audio generation. The setup and usage instructions are provided, including how to generate audio from text and how to use context for better results. The FAQ section clarifies that the model is for audio generation only and does not support text generation or multiple languages effectively. The text also emphasizes the importance of ethical use, prohibiting impersonation, misinformation, and illegal activities. The authors and the Sesame team are credited for the development of this model.

The book offers a vivid portrait of Vienna and the people who shape its cultural landscape, and it delves into the story of a generation of artists who have become a „living cult.“ At its core, the book is a profound exploration of life, death, loss, music, and friendship. Wanda reflects on his unexpected achievements and his enduring resilience.
Three GLP-1 drugs—semaglutide, tirzepatide, and liraglutide—are approved for weight loss in the United States, with semaglutide and tirzepatide being the most preferred. These drugs are expensive, costing about $1000/month, and are rarely covered by insurance. Due to a shortage, compounding pharmacies have been selling these drugs cheaply online, with many Americans taking advantage of this loophole. However, the FDA has declared the shortage over, meaning compounding pharmacies will no longer be able to sell these drugs cheaply as of March 19 (for tirzepatide) and April 22 (for semaglutide). This leaves many people who rely on these drugs for weight management in a difficult situation, as they may not be able to afford the high cost of the drugs from pharmaceutical companies. Telehealth companies are trying to find legal loopholes to continue providing these drugs, but their strategies seem dubious. Meanwhile, pharmaceutical companies like Novo Nordisk and Eli Lilly are exploring new business models to provide these drugs at a slightly reduced price. The community of GLP-1 drug users is feeling anxious but resilient, with some stocking up on medication and others even attempting to make their own. The past few years have shown that a less-regulated supply chain can provide these drugs efficiently and safely, and pharmaceutical companies are now looking into patent-compliant versions of this model.
Experts warn about the ‚crumbling infrastructure‘ of federal government data:
The text discusses the precarious situation of federal statistical agencies in the U.S., such as the Census Bureau and the Bureau of Economic Analysis, due to unstable funding. This instability threatens the reliability and production of crucial government statistics used to track economic and population changes. Budget shortfalls and short-term funding have already led to the discontinuation of some datasets and proposed reductions in survey participants, while modernization efforts are hindered by a lack of multiyear funding. The Census Bureau, preparing for the 2030 head count, faces similar challenges that could affect its field tests and the overall accuracy of the census. Advocates and officials warn that these issues, combined with political pledges to reduce government spending, could further jeopardize the integrity of the country’s data. The situation is compared to „crumbling infrastructure“ that is still functional but in dire need of repair and modernization. Without adequate funding, the statistical agencies may struggle to adapt to increasing complexities in data measurement and declining survey response rates, ultimately affecting the quality and reliability of government statistics. Despite these challenges, advocates see investment in these agencies as a wise move to maintain essential data collection and analysis.
Sweetener aspartame aggravates atherosclerosis through insulin-triggered inflammation - mmc3.pdf:
Aspartame consumption can aggravate atherosclerosis, a disease involving the hardening and narrowing of arteries. The study found that aspartame increases insulin levels through the activation of the parasympathetic nervous system, which in turn triggers inflammation in the arteries. This inflammatory response is mediated by a specific signaling pathway involving CX3CL1 and CX3CR1. When the gene Cx3cr1 is deleted, the pro-atherosclerotic effect of aspartame is completely neutralized, suggesting a potential therapeutic target for treating atherosclerosis and related cerebrocardiovascular diseases.
Metal tariffs make American manufacturing less competitive, can makers say:
The text discusses the impact of recently implemented 25% tariffs on steel and aluminum imports in the U.S. under the Trump administration. The Can Manufacturers Institute (CMI) and the Aluminum Association express concerns about the economic repercussions, particularly the increased production costs for American goods, which could lead to inflation and reduced competitiveness against foreign products.
The CMI highlights that the domestic can industry, which employs over 28,000 people, has seen significant reductions in domestic production lines since the tariffs were implemented in 2018. This has opened the market to cheaper imports, primarily from China. The Aluminum Association notes that the U.S. aluminum industry has invested over $10 billion since 2016, driven by growing demand and a supportive trade environment. However, they emphasize the need for long-term market certainty and a reliable supply of affordable metal, much of which currently comes from Canada. The text also mentions the complex trade dynamics with Canada, Mexico, and China, including retaliatory tariffs and the potential for countermeasures from the EU. Overall, the industries are calling for exemptions and stable trade relationships to mitigate the negative impacts of the tariffs.
Title:Block Diffusion: Interpolating Between Autoregressive and Diffusion Language Models:
The text discusses a new approach to language modeling called block diffusion language models. Unlike traditional autoregressive models, block diffusion models allow for parallelized generation and controllability, but they have historically struggled with likelihood modeling and fixed-length generation. The proposed block diffusion models address these issues by combining elements of discrete denoising diffusion and autoregressive models. This combination enables flexible-length generation and enhances inference efficiency through techniques like KV caching and parallel token sampling. The researchers introduce a set of strategies for building effective block diffusion models, including efficient training algorithms, gradient variance estimators, and data-driven noise schedules to minimize variance. The results show that block diffusion models achieve state-of-the-art performance among diffusion models on language modeling benchmarks and can generate sequences of arbitrary length. The code, model weights, and additional information are available on the project’s webpage.
The author, John Scalzi, purchased a former Methodist church in Bradford, Ohio, not for religious purposes but to create office space for his company, Scalzi Enterprises. The church, built in 1919, was no longer in use due to the congregation’s decline and eventual merger with another church. Scalzi and his wife, Krissy, saw the potential in the building’s ample space and excellent location, purchasing it for $75,000. Despite the need for significant renovations, the building was structurally sound. They transformed the space into offices, a library, and event venues, spending two years on renovations. The local community responded positively to their purchase and renovations, and the Scalzis plan to continue using the space for both their business and community events. They have no plans to make it available for commercial rentals. The church, now called „The Old Church,“ also serves as a gathering place for family events and visits. Despite its unconventional use, Scalzi sees it as a practical and affordable folly.
Functional Tests As A Tree Of Continuations – Evan Miller:
The text discusses the importance of automated tests in maintaining the quality of computer code, particularly focusing on the challenges and inefficiencies of traditional testing methods for functional tests. The author argues that the conventional „list of tests“ approach leads to repetitive and lengthy test code, especially for multi-step processes. This results in a test suite that grows quadratically with the number of steps, making it inefficient.
The proposed solution is to structure functional tests as a „testing tree.“ This tree maps out possible actions at each step, with each node representing a set of assertions and passing a copy of the state to child nodes. This approach reduces code duplication and setup code, pinpoints the source of failing tests, and provides a well-structured hierarchy that mirrors user interactions. The key to implementing this is a stack of databases, where each child test works on a fresh copy of the database, allowing for efficient state management.
The author illustrates this with an example using the Chicago Boss test framework in Erlang, showcasing how the tree structure can be implemented as nested callbacks. This method not only eliminates code duplication but also keeps previous responses in scope, making it easier to compare outputs from different requests.
In conclusion, the testing tree approach offers several benefits, including reduced code duplication, efficient state management, and clearer test structures. The author suggests that this method is particularly suitable for functional tests with many steps and encourages others to consider this approach for writing their own testing frameworks.
AMD’s Strix Halo - Under the Hood:
The text is a transcript of an interview conducted at CES 2025 between George Cozma and Mahesh Subramony, a Senior Fellow at AMD. The discussion primarily revolves around AMD’s upcoming Strix Halo SoC, a significant new product for AMD that integrates a powerful CPU and GPU into a single package. This SoC is designed to meet the needs of consumers and is intended to function as a workhorse in a workstation setting, akin to a Threadripper but in a smaller form factor.
Key takeaways:
Strix Halo features Zen 5 architecture, focusing on power efficiency rather than peak frequency, which is optimized for multi-threaded workloads.
The interconnect between the CPU and GPU dies is redesigned to be more power-efficient and lower latency, using a „sea of wires“ approach instead of a traditional high-speed interface.
The SoC includes 32 megabytes of MALL (Infinity Cache), primarily intended to amplify graphics bandwidth, though it is flexible and can be reallocated for other tasks if needed.
The MALL is coherent with the rest of the system, ensuring data consistency but is primarily used by the GPU.
The data fabric connecting the CPU and GPU operates at a lower clock speed, which is more power-efficient and matches the memory speed.
A single CCD (Core Complex Die) can saturate the memory bandwidth, but the GPU and NPU benefit more from the bandwidth than the CPU.
The interview ends with a light-hearted question about Subramony’s favorite type of cheese, to which he responds with Gorgonzola.
Migrating from AWS to a European Cloud - How We Cut Costs by 62% - Hopsworks:
Hopsworks is a platform for developing and operating AI systems at scale, offering an alternative to other MLOps platforms with superior real-time AI performance and better Python integration.

The animals include monkeys who throw coconuts, a crocodile using a broom for teeth cleaning, a hippo that loves green soap, a lonely elephant humming the tune in the zoo, a lion who becomes gentle when he hears the song, and a cuckoo who sometimes stays quiet. The song is lighthearted and imaginative, using vivid imagery and nonsensical lyrics to create a whimsical atmosphere.
History of maths for beginners!:
The text discusses the book „Math Through the Ages: A Gentle History for Teachers and Others“, coauthored by Fernando Q. Gouvêa and William P. Berlinghoff. The book is praised for its unique structure, which includes a brief historical overview followed by 30 independent sketches on various mathematical topics. These sketches are designed to be pedagogical units, each containing references to a comprehensive bibliography. The text highlights both the strengths and weaknesses of the book, noting its affordability and accessibility for students while pointing out occasional historical inaccuracies and omissions.
The author of the text, who is a historian of mathematics, provides a detailed critique of the book’s content. They praise the book’s approach to teaching the history of mathematics but also point out several factual errors and misunderstandings. For example, the book misattributes certain historical developments to the wrong individuals or periods, such as the introduction of the equal sign and the use of binary arithmetic in Leibniz’s reckoning machine. The text also criticizes the book’s treatment of complex numbers, the history of computing, and the contributions of various mathematicians like Brahmagupta and Ada Lovelace.
Despite these criticisms, the author acknowledges that the book is a valuable resource for students and educators, offering a comprehensive and engaging introduction to the history of mathematics. The text concludes by recommending the book as a good starting point for those interested in the subject, despite its flaws. The author also provides additional reading recommendations and resources for further exploration.
Why Great Engineering Orgs Thrive on „Normal“ Engineers:
The text is an argument by Charity Majors, a software engineer and cofounder of Honeycomb.io, against the myth of the „10x engineer“—an engineer who is supposedly ten times more productive or skilled than their peers. While Majors acknowledges that there are exceptional engineers, she argues that the concept of a 10x engineer is flawed and misleading. Her main points are:
Measuring Productivity: Productivity in software engineering is complex and multifaceted, depending on various factors like the type of project, programming languages, and additional skills required. It’s not something that can be standardized or easily measured. Therefore, labeling someone as a 10x engineer based on productivity is not feasible.
Team Ownership: Software is owned by teams, not individuals. The speed at which a team can collectively write, test, review, and maintain software matters more than the speed of an individual engineer. Individual engineers can be bottlenecks or single points of failure, so it’s crucial to have systems where teams own the software.
Value of Normal Engineers: Great engineering organizations are those where normal engineers can make significant contributions and move the business forward. These organizations focus on building systems that enable all engineers to be productive, rather than relying on a few exceptional individuals.
Hiring Practices: Majors advocates for hiring the „right“ people, not just the „best.“ This approach emphasizes unique strengths, inclusivity, and team composition. She argues that this creates an environment where engineers can grow and become world-class, and where top performers want to stay and train the next generation.
In summary, Majors challenges the idea of the 10x engineer and emphasizes the importance of teamwork, inclusive hiring practices, and creating environments where all engineers can thrive and contribute meaningfully.

IO devices and latency — PlanetScale:
The text discusses the evolution of non-volatile storage in computer systems, from tape drives to hard disk drives (HDDs) and solid state drives (SSDs), and the impact of moving to cloud-based storage. Non-volatile storage is crucial for retaining data even when the computer is powered off, unlike volatile storage which loses data when power is lost.
Tape drives, used since the 1950s, are still relevant for massive, infrequently accessed data due to their cost-effectiveness and long shelf life. However, they suffer from high latency for random reads and writes. HDDs, introduced later, offered lower latency and more efficient data access due to their spinning disks and read/write heads. SSDs further improved performance by eliminating mechanical components, relying instead on electronic signaling for data storage and retrieval. They offer faster access times but still face challenges like garbage collection and data organization.
The shift to cloud-based storage, while offering scalability and durability through replication, introduces latency and IOPS (Input/Output Operations Per Second) limitations due to network-attached storage. This is because data must travel over a network, increasing the time it takes for read and write operations. To mitigate these issues, PlanetScale introduced Metal, a solution that uses locally attached NVMe SSDs for cloud databases, providing low latency, high IOPS, and no artificial caps on IO operations. Metal also ensures data durability through replication and easy scalability by allowing seamless resizing of storage.
The text is a critical commentary on Volkswagen (VW) and its CEO, Oliver Blume, focusing on the company’s history of strategic failures and environmental negligence. The author argues that VW’s recent innovations are overshadowed by its past misdeeds, such as the diesel emissions scandal and its active lobbying against electric vehicles (EVs) and in favor of fossil fuels. The author expresses frustration that VW is now seeking state support, despite having known about climate change since the 1970s. The commentary calls for stronger accountability for VW’s executives and suggests that the company’s facilities should be used for more meaningful purposes. The text ends on a pessimistic note, implying that VW’s actions may contribute to environmental disaster.
Die Panikmache mit den Blackouts:
The text discusses the misconception that Germany is at risk of a large-scale power outage (blackout) this winter. Despite claims, especially from right-wing and conspiracy circles, that a blackout is imminent due to an energy policy over-reliant on renewable energy, experts argue that such a scenario is highly unlikely.
Key points include:
The primary cause of blackouts is typically issues in the transmission of electricity, such as failures in key power lines, rather than an insufficient generation of electricity. Dirk Witthaut, an expert from the Forschungszentrum Jülich, describes warnings about blackouts as „very irresponsible“ and notes that the network operators have comprehensive contingency plans to restore power quickly after a blackout.
Witthaut emphasizes that the critical factor for the stability of the energy system is the expansion of the power grid, not just the generation of electricity. While there can be periods of very low renewable energy production, these have led to high prices but not to blackouts.
In the future, overproduction may be a more significant concern than shortages. The government and network operators are continuously improving safety measures to prevent complete network failures.
The Bundesamt für Bevölkerungsschutz und Katastrophenhilfe (BBK) confirms that Germany’s power supply is very secure even on an international scale. Despite reassurances, the BBK encourages the public to be prepared for emergencies, including power outages, as part of a general safety strategy.
In summary, while the idea of a widespread blackout in Germany is a popular talking point, especially in certain political circles, experts agree that this is very unlikely due to robust network infrastructure, contingency planning, and continuous monitoring. It’s important for the public to be prepared for emergencies, but the threat of a widespread blackout is not imminent.
Republicans Quietly Cede Power to Undo Trump’s Tariffs on Canada, Mexico and China:
House Republicans have taken steps to prevent a vote on ending President Trump’s tariffs on Mexico, Canada, and China. They did this by adding a provision to a procedural measure that essentially suspends the ability of Congress to terminate these tariffs for the rest of the year. This move is seen as an attempt to avoid forcing Republicans to publicly take a stand on the divisive issue of tariffs, especially given the economic concerns surrounding them.
The Democrats, who had planned to force a vote on this matter, criticized the Republicans‘ maneuver, arguing that it undermines Congress’s ability to hold the president accountable and act in the best interests of the American people. While Democrats in the Senate could still try to push for a vote, any resolution would ultimately need to pass both chambers and be signed by Trump, which is unlikely given his support for the tariffs.
The text discusses the cancellation of an event called the „Fnord-Show“ due to overwhelming circumstances. The author then delves into a recent political maneuver by Republicans in response to a state of emergency declared by President Trump. The Republicans, instead of challenging the declaration directly, declared the remainder of the year as a single day. This unusual move effectively bypasses a law that allows Congress to end a presidential disaster declaration, undermining the principle of separation of powers. The author expresses dismay at this political maneuver, questioning the integrity of the system.

Datenschutz als Ware: Wie Einkaufs-Apps unser Verhalten und unsere Gesellschaft verändern:
The text discusses the increasing practice of companies offering discounts or benefits in exchange for personal data, which is leading to a normalization of surveillance and a devaluation of privacy. This phenomenon, exemplified by supermarket apps, extends to various sectors like streaming services, social networks, and insurance companies. The author argues that this trend is creating a two-tiered society where those who can afford to forgo discounts maintain their privacy, while those who cannot are compelled to share their data.
The societal implications are profound: privacy is becoming a privilege rather than a right, and data is being used to influence consumer behavior and market dynamics. The lack of transparency in data usage exacerbates this issue, leading to a gradual loss of consumer control over their personal information.
The author calls for regulatory measures to ensure transparency and to offer alternatives that do not rely on surveillance. The text concludes with an appeal to consumers to reject apps and services that trade personal data for benefits, emphasizing that privacy should be a fundamental right rather than a commodity. The long-term effects of data surveillance are concerning, potentially leading to a society where privacy is eroded and consumer behavior is increasingly controlled.

Title:Token Assorted: Mixing Latent and Text Tokens for Improved Language Model Reasoning:
The text discusses a method to improve the efficiency of Large Language Models (LLMs) in reasoning and planning tasks. Traditional methods, which involve detailed step-by-step text, can be computationally expensive due to their length. The proposed solution is a hybrid representation that uses latent discrete tokens generated by a model called VQ-VAE to abstract the initial reasoning steps, thereby reducing the input length. This approach is tested in two scenarios: training from scratch for a specific problem and fine-tuning LLMs for both logical and mathematical reasoning tasks. The training procedure involves mixing latent and text tokens to facilitate quick adaptation to new tokens. The results show that this method outperforms baseline methods in various benchmarks, indicating its effectiveness in making LLM reasoning more efficient.

What Made the Irish Famine So Deadly:
The text delves into the historical context and implications of the Great Hunger, a devastating famine that struck Ireland in the mid-19th century. It highlights how this event was shaped by contemporary beliefs that the poor were responsible for their own suffering and that market forces should not be intervened with, even in times of crisis. The famine, caused by a potato blight, resulted in widespread death and emigration, profoundly altering Irish society and leaving a lasting impact on its culture and politics.
One of the key points is the contrast between different narratives of the famine. Oscar Wilde’s play „The Importance of Being Earnest“ trivializes the food crisis, highlighting the disconnect between the English upper class and the Irish poor. In contrast, William Wilde’s „Tables of Deaths“ provides a stark, data-driven account of the catastrophe, while Jane Wilde’s poetry expresses the anger and grief of the Irish people. The famine’s scale and complexity make it difficult to comprehend, as it challenged the Victorian belief in progress and exposed the brutal realities of capitalism and class inequality.
The text also explores the ideological underpinnings of the British response to the famine, which was marked by a refusal to acknowledge the structural causes of Irish poverty and a rigid adherence to free-market principles. This response was driven by a belief in the moral failings of the poor and a faith in the market, leading to policies that exacerbated the crisis. The famine’s legacy includes a profound sense of loss and a deep-seated distrust of British rule, which continues to resonate in Irish society today. The text concludes by emphasizing the modern relevance of the Great Hunger, warning that similar mindsets and policies could lead to contemporary disasters.
A 19yo woman graduated from high school with honors even though she can’t read:
The text discusses the challenges and disparities within the education system, primarily focusing on the experiences of a student with severe dyslexia who was not diagnosed until her final year of high school. The key takeaways are as follows:
The student’s journey highlights the systemic issues in education, where teachers are overworked and cases like hers often fall through the cracks. Special education is noted as a significant financial burden, with school districts like Hartford spending a substantial portion of their budget on special education students. This often leads to a reduction in resources for general education programs.
The conversation also touches on the economic challenges of special education, where the returns on investment can be limited despite the high costs. The complexity of balancing resources between special education and general education is a significant issue, and federal requirements for special education funding add to the financial strain on school districts. There is a need for more competent school psychologists to better identify and support students with learning disabilities. The field of school psychology is seen as underpaid and undervalued, which can lead to a lack of competent professionals.
The text also highlights the disparities in funding between majority non-white and majority white school districts, with non-white districts receiving significantly less funding. This funding gap is part of the broader discussion about equity in public education. The overall message is a critique of the education system’s inability to adequately support students with learning disabilities and the financial and structural challenges that hinder effective education for all students.
