Summary: Hardening the Firefox Frontend with Content Security Policies

The main user interface (UI) of Firefox is built using web technologies like HTML, CSS, and JavaScript, making it vulnerable to injection attacks, particularly Cross-Site Scripting (XSS). To protect against these attacks, Firefox uses a method called inter-process communication (IPC) to separate the UI from web content running in lower-privileged processes.

In a recent hacking contest, an exploit was found that allowed bypassing this separation by using inline JavaScript event handlers. To mitigate such risks, Firefox is implementing Content-Security-Policies (CSP) to restrict script execution in the UI. The team has successfully removed over 600 inline event handlers from the main UI document, enhancing security.

Developers can replace inline event handlers with safer methods, such as using addEventListener. While the main UI (browser.xhtml) is now more secure, Firefox plans to implement CSPs in other parts of the application, aiming to block all dynamic code execution and provide a more secure browser.

The improvements will be included in Firefox 138, significantly raising the difficulty for attackers and improving the overall security of the browser.

Summary of "American Disruption"

On April 9, 2025, the author reflects on three previous articles that fell short in addressing key issues surrounding American manufacturing and technology. The author acknowledges a need for clearer frameworks, particularly in light of recent tariffs imposed under the Trump administration, which have negatively impacted the tech industry by increasing costs for essential components.

The concept of "disruption," coined by Professor Clayton Christensen, explains how smaller companies can challenge established businesses by targeting overlooked market segments. This process has been evident in the semiconductor industry, where manufacturing jobs moved to Asia due to lower labor costs, while the U.S. retained higher-margin chip fabrication.

The text highlights the transformation in globalization driven by advancements in transportation, communication, and shipping, which enabled multinational corporations to design products in the U.S. and manufacture them in lower-cost countries. This shift has created economic dependence on these foreign manufacturing capabilities, raising concerns about national security.

The author criticizes blanket tariffs, arguing that they harm the U.S. economy by reducing demand and complicating supply chains. Instead, targeted tariffs on specific components could encourage sourcing from trusted allies. The piece also emphasizes the need for the U.S. to revitalize its chip manufacturing capabilities to remain competitive, especially as technology evolves towards automation and AI.

In conclusion, the author expresses sadness over the changing landscape of technology, where political considerations overshadow economic logic. The call to action is for a strategic vision that embraces innovation rather than regressing to outdated practices.

The article discusses the concept of "Sun-like" stars in the context of exoplanet research. The author reflects on their childhood fascination with the idea of planets orbiting stars similar to our Sun, particularly Alpha Centauri. However, they note that Alpha Centauri is a complex system with two stars—Centauri A and B—and possibly a third, Proxima Centauri.

The term "Sun-like" is not well-defined and can refer to various types of stars, including G-class (like the Sun), K-class, and sometimes F-class stars. G-class stars are stable and have lifespans of about 10 billion years. K-class stars, while not technically "Sun-like," are cooler and longer-lived, making them potential candidates for habitable planets. The article emphasizes the importance of clarity in using the term "Sun-like," as it can significantly affect public understanding and perceptions of exoplanet research.

The author points out that when scientists make claims about Earth-like planets around "Sun-like" stars, it can refer to a small percentage of stars (G-class) or a larger range (including K and F-class), affecting estimates of how many habitable planets might exist in the galaxy. They argue that careful definition is necessary to avoid public confusion, which could impact support for scientific research in this area.

In conclusion, while there is growing interest in exoplanets, clear communication about what "Sun-like" means is essential to ensure accurate public understanding and support for ongoing research.

They realized that instead of a post, they were preparing for a presentation and decided to share some additional thoughts that didn't make it into the talk.

Key Points:

1. Tags vs. Function Calls:

   • Tags (like <p>Hello</p>) are often nouns, while function calls (like alert('Hello')) are verbs. This difference affects how we use them in programming.
   • Tags are typically used for creating structures in a nested way, while function calls are used for executing actions in a sequence.

2. Blueprints and Recipes:

   • Tags create blueprints representing structures, while function calls act as recipes for processes.
   • Blueprints describe what something is made of without a specific order, while recipes need to be followed step by step.

3. Asynchronous Programming:

   • The author discusses the challenges of calling functions on remote computers and introduces the concept of asynchronous functions (async/await) to manage delays in execution.
   • They suggest a new syntax for remote calls (like import rpc) to ensure proper handling of function calls across different computers.

4. Potential Function Calls:

   • The author considers scenarios where you might call a function that doesn't respond, leading to the idea of "potential calls" that don't guarantee success and don’t pause the execution flow.

Overall, the text explores the relationship between different programming concepts, particularly in the context of React and asynchronous operations, emphasizing how we understand and manage function calls and their structure.

Douglas Lenat's ambitious Cyc project, aimed at creating artificial general intelligence through symbolic logic, has ultimately failed after 40 years of effort. His journey started with earlier AI systems that showed promise but quickly became limited due to a lack of knowledge. In 1985, Lenat founded Cyc to manually encode vast amounts of common sense knowledge, believing it would enable true machine learning. Despite accumulating around 30 million facts at a cost of $200 million, Cyc never achieved the anticipated breakthroughs.

Cyc's funding has mainly come from military and commercial sources, and while it has maintained financial stability, its applications have largely been similar to existing expert systems, offering no significant advantages. The project has been insular, with little academic collaboration or recognition outside Cycorp. Lenat has consistently rejected alternative AI approaches, holding firm to his symbolic-logical vision.

As of 2025, there is no indication that Cyc will reach the level of general intelligence. The slow failure of this project highlights the limitations of the symbolic-logical approach to AI.

Lenat's earlier work, including the Automated Mathematician (AM) and EURISKO, revealed significant lessons about AI development. AM, which autonomously discovered mathematical concepts, eventually "exhausted" itself due to a limited set of heuristics. EURISKO aimed to overcome this by allowing the system to discover new heuristics but also faced limitations, leading Lenat to conclude that genuine AI requires a rich foundation of common sense knowledge.

Overall, Lenat's experiences underscore the complexities of AI development and the challenges of achieving true general intelligence.

Summary: Small Town America vs. Big Box Stores

Sean Donaghy and his wife, Amy, run the Washington General Store in a small town in Maine, which serves as a local gathering place. However, their community faces a threat from a new Dollar General store set to open, which many locals, including Donaghy, believe will harm their town's identity and economy. Residents are concerned that big box stores like Dollar General take money out of the community, hurt local businesses, and lead to negative social impacts.

A 2023 report indicates that dollar stores often replace local grocers, limiting access to fresh food and draining local wealth. Despite this, Dollar General continues to expand rapidly across the U.S. Some local businesses adapt by finding unique niches, but many small businesses struggle against the advantages that big corporations receive, such as government subsidies and tax breaks.

Communities are pushing back against the expansion of dollar stores. For example, residents in Prairieton, Indiana, successfully blocked a new Dollar General by advocating for more suitable developments. Other towns have enacted laws to restrict where dollar stores can open.

Local leaders are encouraged to rethink policies that favor big box stores over local businesses. Creating fairer land-use regulations and investing in local entrepreneurship can help maintain the economic health of communities and ensure that money stays within local economies rather than being siphoned off by large corporations.

Summary of the NTATV Project:

The NTATV project aims to run Windows NT operating systems (like Windows XP and Windows 2003) on the original Apple TV. Created by DistroHopper39B with assistance from ReactOS developers, the project has made significant progress over two years.

Key Achievements:

• Windows XP and Windows Server 2003 can now boot successfully on the original Apple TV.
• Drivers for basic functionalities (like PCI, USB, and video) are mostly working.
• ReactOS is not fully functional yet due to hardware limitations.

Current Status of Functionality:

• Windows XP: Most functions work, but HDMI audio and the remote control are broken.
• Windows Server 2003: Similar to XP, but with some untested features.
• ReactOS: Many features are non-functional, mainly due to PCI issues.

Challenges:

• The Apple TV's unique firmware (EFI-only) complicates running Windows, which typically requires legacy BIOS.
• The project involved creating a custom bootloader (FreeLoader) to make this possible.

Known Issues:

• HDMI audio is unlikely to work due to the Apple TV's unusual setup.
• There are various display and connection problems that users may encounter.

Background: The project was inspired by earlier videos about hacking the Apple TV, leading to ongoing development and exploration of its capabilities.

Source Code and Contributions: The source code is available on GitHub, and there's a detailed guide on how to build and run the project.

Recent Updates:

• The project has had updates to improve driver support and boot capabilities, with the latest version being v0.2.

For more information, guides, and updates, users can check the project's GitHub page.

Man pages, which are used for documentation in Unix-like systems, do support linking and re-flowing text, but the programs that read them do not. Users often complain that man pages lack internal links and do not adjust to narrower windows. While these features are supported in the man page formats (mdoc and legacy man), the readers like the man command do not implement them properly.

Man pages are written using specific macros that mark different parts of the text, such as section headers and document descriptions. Two important macros, .Xr and .Sx, can create links to other manual pages or sections within the same page. These links work when the man pages are converted to HTML for browsers but not in terminal displays.

The conclusion is that we need better man page readers that can follow links and adapt text for different window sizes. Currently, the man command formats pages and sends them to a pager (like less), which does not support these features. Improvements are needed for a better user experience.

Summary of "Better Typography with text-wrap: pretty" by Jen Simmons

On April 8, 2025, Jen Simmons discusses the new CSS property text-wrap: pretty, recently introduced in Safari Technology Preview. This feature enhances web typography by using advanced algorithms that improve text layout, addressing common issues like short last lines, uneven line lengths (bad rag), and poor hyphenation.

Historically, typography was carefully crafted by hand, but digital text layout has relied on simpler methods that often lead to visual problems. text-wrap: pretty allows browsers to evaluate entire paragraphs for better text wrapping, making reading easier and more visually appealing.

Key challenges in web typography include:

• Short Last Lines: Avoid having a single word alone at the end of a paragraph.
• Bad Rag: Minimize jagged text edges for better readability.
• Hyphenation Issues: Reduce excessive hyphenation that can distract readers.
• Typographic Rivers: Prevent whitespace patterns that disrupt text flow.

While existing browsers have limitations—like only addressing the last few lines—Safari's implementation aims to enhance the entire text block. The text-wrap: balance option is also discussed, which helps standardize line lengths but may not fill the container's width.

Performance is a concern, but Safari manages to implement these features without slowing down web pages, even with lots of content. Developers are encouraged to test these new properties and report any performance issues.

In summary, text-wrap: pretty and related options offer web designers powerful tools to create more attractive and readable text layouts, bridging traditional typography's elegance with modern web design needs. Users can experiment with these features in Safari Technology Preview and provide feedback on their experiences.

Marb, a citizen scientist, built a DIY experimental reactor based on the Birkeland-Eyde process, which converts nitrogen from the air into nitric acid using electrical arcs. Although this process is outdated due to its high energy demands, Marb is focused on the science rather than practical fertilizer production.

To control the electrical arcs, Marb used an Arduino UNO Rev3, which manages the power flow to the electrodes. His reactor also includes a system for drying air and sensors to monitor conditions. While he demonstrated the reactor in a video, he has not optimized the process for better results yet, but plans to provide more details if there is sufficient interest.

On April 8, 2025, the author discusses updates for their upcoming book "Logic for Programmers," focusing on rewriting a chapter about Logic Programming Languages. Instead of typical puzzle-solving examples, they aim to include practical applications of Prolog that can be useful in everyday work.

The author shares a video game puzzle solved with Prolog by a friend, Pablo Meier, and presents their own elegant solution to a related problem involving student scores from a test. They explain how to compute the score based on a student's answers compared to the answer key, highlighting Prolog's ability to handle logical queries both ways: calculating scores or inferring answers.

The program they develop is concise, using only 15 lines of code compared to the original 80 lines. They conclude by noting that while puzzles can be fun, the real examples in their book will focus on more practical scenarios, like analyzing version control or planning infrastructure changes.

Overall, the author emphasizes making Prolog applications more relevant to real-world programming tasks rather than just puzzles.

Terence Tao recently challenged mathematicians to express the factorial of 300,000 (300K!) as a product of 300,000 factors, each greater than 100,000. He demonstrated that it could be done with factors larger than 90,000, and now aims for those larger than 100,000.

The strategy involves starting with an odd number (B), which is a product of 300,000 odd numbers greater than 100,000, and adjusting it to meet the criteria. Tao identified "B-heavy primes" (those appearing more frequently in B than in 300K!) and "N!-heavy primes" (more common in 300K!). The goal is to replace B-heavy primes with larger N!-heavy primes or powers of 2 to achieve the desired decomposition.

Using the Racket programming language, the author implemented a memoized method for factorizing numbers, allowing for efficient calculations of both 300K! and the number B. Initial attempts at balancing the factorization were made, and results showed that B had more primes than 300K!.

The findings include:

1. The factorization of 300K! has a significant number of primes and multiplicities, especially for the prime number 2.
2. The balancing of primes between N! and B was attempted using different methods, with varying success in conserving powers of 2.
3. A method to optimize the replacement of primes was developed, showing success in decomposing 300K! into required factors.

Ultimately, the author successfully demonstrated the decomposition of 300K! into factors larger than 100K, confirming that the challenge posed by Tao could be met. Further brute force checks were suggested to refine the approach for different values.

Summary of the Decline of the U.S. Machine-Tool Industry and Prospects for Recovery

The U.S. machine-tool industry, crucial for manufacturing and defense, has faced significant decline since the early 1980s. Key points include:

1. Importance of Machine Tools: These tools shape metal and are essential for manufacturing technologies. A weak domestic industry risks U.S. manufacturers' access to the latest technologies.

2. Decline in the 1980s: At the start of the 1980s, the U.S. was the largest producer of machine tools and had developed revolutionary computer numerical control (CNC) technology. By the end of the decade, production had fallen to less than half of Japan's and Germany’s output.

3. Reasons for Decline: The study identified four main causes:

   • A sharp drop in domestic demand for machine tools.
   • U.S. firms struggled to respond to fluctuating demand, allowing Japanese firms to fill orders faster.
   • Japanese competitors gained an advantage in both product and process technologies.
   • A strong U.S. dollar made American products less competitive.

4. Challenges in Recovery: From 1983 to 1992, the industry did not rebound due to various issues:

   • Insufficient large firms and poor cooperation among smaller ones.
   • Difficulty in obtaining capital for investments.
   • Low skill levels in the labor force and inadequate training systems.
   • Failure to effectively turn technological research into market products.
   • Slow domestic demand for new technologies.
   • Weak export capacity and infrastructure.

5. Prospects for Recovery: Despite challenges, there are reasons for optimism:

   • Restructuring within U.S. firms and a recent increase in domestic demand.
   • Japan's lead in CNC technology is declining, and the U.S. has a research advantage in several key areas.

6. Recommended Government Policies: The study suggests a three-part strategy for recovery:

   • Foster local networks among machine-tool manufacturers, users, and suppliers to promote technology adoption.
   • Increase investments in manufacturing infrastructure and research.
   • Streamline export processes and support international sales to enhance global competitiveness.

In conclusion, while the U.S. machine-tool industry faces significant obstacles, strategic planning and government support could help it recover and thrive in the global market.

In the small town of Kawara, Fukuoka Prefecture, children are enthusiastically collecting trading cards featuring local middle-aged men, known as "ojisan," instead of the usual Pokémon cards. This unique card game, created by Eri Miyahara of the Saidosho Community Council, aims to connect kids with their community's older generations.

The Ojisan trading cards showcase 47 different local men, each with special abilities and humorous descriptions. Popular cards include Mr. Honda, a former fire chief, and Mr. Fujii, a community volunteer. The game started as a collection but evolved into battles where kids compare card stats and skills. The rarity of cards is based on real community contributions, encouraging kids to engage more with local events.

Despite the limited availability, demand for the cards is high, with kids saving money to buy them at the community center. This initiative has successfully doubled participation in local activities, helping kids appreciate and connect with their community's elders.

Summary of "Analytic Combinatorics -- A Worked Example"

In this blog post, the author explores a combinatorial problem about counting unordered rooted ternary trees with ( n ) nodes. They first detail how to count ordered ternary trees, which can be either a leaf or an internal node with up to three ordered children. The generating function for these trees is derived, leading to an asymptotic approximation using analytic combinatorics techniques.

The author successfully approximates the number of ordered trees with a formula involving constants and powers of ( n ), demonstrating the effectiveness of this method. They also explain a more complex problem: counting unordered trees up to graph isomorphism. For this, they use Pólya-Redfield counting principles to derive a new generating function.

The key steps include:

1. Defining the Problem: Understanding the characteristics of the trees being counted.
2. Generating Functions: Establishing a function that counts the trees based on their structure.
3. Asymptotic Analysis: Using singularity analysis to approximate the number of trees as ( n ) grows large.
4. Practical Computation: Implementing calculations in Sage, a mathematics software system, to visualize the results and refine approximations.

The author expresses excitement about learning and sharing their findings, noting that their approach has yielded reliable approximations that match known sequences in combinatorial databases. They conclude with an invitation for readers to further explore related problems and methods in analytic combinatorics.

The user, cbscpe, shared an update about their project building a PDP-11/Hack computer. After an unsatisfactory previous attempt, they created a new design for a single-board computer (SBC) based on the DCJ11, which now includes an expansion slot, enhancing its capabilities. The user received the printed circuit boards (PCBs) and started testing the prototype, which required some minor adjustments (ECO). They highlighted that the computer is powered by a USB to Serial/TTL adapter and consumes less than 200mA. The design uses traditional through-hole components for most parts, with only surface-mounted devices for capacitors and resistors. They also integrated a reset button and logic for proper operation. A screenshot of the test program results was included, albeit with a poor picture quality.

Summary: Recognizing Woodpeckers by Their Drumming Sounds

Woodpeckers create distinctive drumming sounds, especially noticeable in spring. This drumming is a way for them to communicate, establish territory, and attract mates. While drumming is less melodic than birdsong, you can differentiate species by listening for variations in speed, duration, and rhythm.

Key Points:

1. Drumming Purpose: Woodpeckers drum all year, but it's more frequent in spring. They drum to communicate, not to find food.

2. Drumming Patterns:

   • Downy Woodpecker: Slow and short drumming (about 17 beats per second).
   • Hairy Woodpecker: Faster and longer drumming (about 26 beats per second).
   • Nuttall’s Woodpecker: Intermediate speed (around 20 beats per second).
   • Ladder-backed Woodpecker: Very fast drumming (about 30 beats per second).
   • Northern Flicker: Longer drumming at about 23 beats per second, often with pauses.
   • Sapsuckers: Unique rhythms with introductory rolls and multiple fast taps.
   • Pileated Woodpecker: Slow drumming with a powerful sound, creating a fadeaway effect.

3. Listening Techniques: Observing spectrograms can help identify the timing and pattern of drumming sounds, aiding in species recognition.

In 1948, Rollie Free set the motorcycle world speed record at the Bonneville Salt Flats in Utah, reaching 150.313 miles per hour. To minimize wind resistance, he lay horizontally on his bike and wore only swim trunks during the attempt. A famous photo by Peter Stackpole captured this moment, making it one of the most iconic images in motorcycle history. While Free's record has since been surpassed—current record is 376.363 mph set in 2010 by Rocky Robinson—the image of Free remains popular and celebrated for its unique portrayal of the event.

The IBM System/360, launched in 1964, was a groundbreaking mainframe computer that transformed the computing industry and how businesses operated. IBM invested $5 billion to develop it, facing significant internal conflicts and challenges. Prior to the S/360, IBM's popular 1401 model had limitations that led to customer demands for a more expandable and compatible system.

To create the S/360, IBM had to unite different engineering teams within the company, overcoming rivalries and creating a cohesive product line. The design focused on compatibility, allowing users to upgrade their systems without needing to rewrite software.

Despite its ambitious goals, the launch was fraught with issues, including production delays and software challenges. However, the announcement generated massive interest, leading to over 100,000 orders in the first month.

By the late 1960s, the S/360 had solidified IBM's dominance in the computer market, significantly boosting demand for computing technology overall. The project was a monumental success, but it also caused immense stress and turmoil within the company, leading executives to vow never to undertake such a massive endeavor again.

It's the rainy season in Malawi, and churchgoers are leaving services, dressed nicely. Couples walk together, avoiding potholes, as they pass by shops and bars, where some stop for drinks. Eventually, they arrive at a dusty area where thousands are gathered for a football match. Dust from the game settles on their clothes, creating a typical Sunday scene. However, in Dzaleka, a refugee camp that has been housing people from central African conflicts since 1994, the situation is different: the attendees aren't relaxing after a workweek.

HNSW - Hierarchical Navigable Small Worlds

HNSW is a method for quickly finding the nearest neighbors of vector embeddings using a graph structure. Here are the key points:

• Structure: HNSW organizes nodes in layers. The top layers have fewer nodes, while the bottom layers have more.
• Insertion: When a new node is added, it randomly chooses a layer and is inserted there, as well as in all layers below it.
• Searching: Searches start at the top layer and move down, keeping track of the closest nodes found. The process continues until the closest node is found or the search reaches the bottom layer.
• Implementation: The code is about 500 lines long, written in modern C++, and uses Eigen for faster calculations.

Example Code: The provided example demonstrates how to create an index for 128-dimensional vectors, add items, and search for the nearest neighbors.

Compilation Instructions: To compile the code, create a build directory, run CMake, and then make the project.

Over the past two weeks, Google and OpenAI introduced their new image generation capabilities, which allow AI to create images directly rather than relying on separate tools. This is called multimodal image generation, where the AI constructs images piece by piece, similar to how it forms sentences with words. This advancement results in much clearer and more accurate images, avoiding issues like unwanted elements appearing in the picture.

These systems allow for more sophisticated prompts and iterative changes, meaning users can refine images more effectively than before. For example, users can ask the AI to create specific visuals or make adjustments to existing images, such as changing colors or correcting errors. The technology is evolving rapidly, and while it can produce impressive results, it’s not perfect yet.

The potential applications for this technology are vast, including creating advertisements, website mockups, and even visual recipes. However, the rise of AI in art also raises important ethical questions about copyright, ownership, and the authenticity of generated art. As AI continues to advance in visual creation, society will need to carefully consider how to navigate these changes and their implications for creative professions.

Summary of Neuroplasticity in Pre-trained LLMs:

Neuroplasticity can be applied to pre-trained language models (LLMs) in real-time using a new method called Neural Graffiti. This technique integrates ideas from liquid neural networks and static transformers through a component known as the Spray Layer.

The Spray Layer allows for the injection of memory and information into the model's final inference stages without the need for retraining. This process is inspired by how the human brain adapts and changes over time. Instead of guaranteeing specific outputs, it subtly shifts the model's understanding and relationships between concepts based on interactions, creating a kind of evolving memory.

Key features include:

• It does not force the model to produce specific words but influences its overall "thinking."
• The effects of the memory injection can be tracked and measured.
• Over time, the model can develop preferences, such as showing more warmth towards topics like dogs after being told about them.

The goal is to create models with a more active personality and enhanced curiosity, resembling self-awareness at a neuron level. However, this approach may not be suitable for business applications, as it could result in models that develop unique, specific personalities over time, similar to digital personas.

On the Hawaiian island of O'ahu, a new type of ecosystem is forming due to human actions, blending various non-native species from around the world. This "freakosystem" showcases how human influence has transformed the environment, resulting in forests populated mainly by introduced plants and animals, rather than native species.

O'ahu's forests, once rich in unique native flora and fauna, have been drastically altered since humans arrived. Many native species have gone extinct due to habitat destruction and the introduction of invasive animals. Today, the island's ecosystems are a mix of exotic species, including Brazilian plants and Asian birds, which have created a new, self-sustaining environment.

Ecologists are studying O'ahu as a model for understanding the future of global ecosystems, with estimates suggesting that up to half of the world's land could become novel ecosystems by 2100. These ecosystems challenge traditional conservation methods, as many native species have been lost, and new strategies are needed to manage the remaining biodiversity.

Research on O'ahu illustrates the complex interactions between native and non-native species, leading to innovative conservation strategies that utilize both to protect remaining native plants. The situation on O'ahu serves as a cautionary tale for similar ecosystems worldwide, highlighting the urgent need to adapt conservation practices in response to ongoing environmental changes.

Summary: Intelligence Evolved at Least Twice in Vertebrate Animals

Recent research suggests that intelligence in vertebrates, which includes birds and mammals, evolved independently at least twice. Birds display advanced cognitive abilities despite having smaller, differently structured brains than mammals. While it was once believed that both groups inherited their intelligence from a common ancestor, new studies indicate that they developed their complex neural circuits separately.

Research has shown that while bird and mammal brains have similar neural circuits, they evolved these structures in different ways and at different times. This challenges the long-held belief that brain structures must resemble one another to serve similar functions. Instead, both groups utilized different types of neurons to achieve comparable cognitive capabilities.

These findings highlight that evolution can lead to similar solutions for complex problems, a process known as convergent evolution. Understanding how different species develop intelligence can provide insights into our own cognitive processes and even aid in artificial intelligence development. This research encourages a broader perspective on intelligence, moving away from the idea that humans are the pinnacle of cognitive evolution.

Summary of Cogito v1 Preview: IDA and General Superintelligence (April 8, 2025)

Deep Cogito has released powerful language models (LLMs) in various sizes (3B, 8B, 14B, 32B, and 70B) under an open license. These models outperform other leading models in their category, including LLaMA and DeepSeek.

The models are trained using a method called Iterated Distillation and Amplification (IDA), which allows for self-improvement without being limited by the intelligence of human overseers. Each model can either provide direct answers or reflect before responding, enhancing reasoning capabilities.

Upcoming releases will include even larger models (109B, 400B, and 671B) and improved versions of current models. Users can access these models via Huggingface, Ollama, or APIs from Fireworks AI and Together AI.

IDA improves intelligence through two main steps:

1. Amplification - using more computation for better solutions.
2. Distillation - refining these solutions into the model's own parameters.

This iterative process creates a cycle of continuous improvement, making the models more efficient and capable than traditional methods. Initial tests show promising results across various tasks.

Deep Cogito aims to achieve general superintelligence by combining advanced reasoning with iterative self-improvement, and they are actively seeking top talent to join their mission. All models will be available as open-source.

Meta recently released two new AI models, Llama 4 Scout and Llama 4 Maverick. Maverick claimed to outperform competitors like GPT-4 and Gemini 2.0 on various benchmarks, quickly ranking second on LMArena, a site where AI models are compared. However, it was later revealed that the version tested on LMArena was a customized, experimental model not available to the public, which raised concerns about fairness in benchmarking.

LMArena's management criticized Meta for not clearly stating that the tested model was optimized for specific tasks. Meta defended its approach, stating that it experiments with different model variations and has released an open-source version for developers. The controversy highlights challenges in AI benchmarking, as companies may present tailored versions of models that don't reflect the public's experience.

This situation illustrates how benchmarks can be manipulated and the growing competition in AI development, with Meta eager to establish itself as a leader in the field.

Summary of "Using Token Sequences to Iterate Ranges" by Barry Revzin

The article discusses the performance issues related to using C++ Ranges, particularly how certain range adaptors can introduce inefficiencies. It focuses on two main problems: the redundant checks made by functions like views::filter and views::take_while, which can lead to unnecessary comparisons and slow down performance.

Key Points:

1. C++ Range Basics: The standard way to iterate over a range in C++ involves using iterators and a loop structure. However, when customizing this behavior with range adaptors, performance can suffer.

2. Performance Issues:

   • Using views::filter can lead to redundant comparisons.
   • The combination of views::take_while and views::filter can exacerbate this issue, leading to multiple function calls and checks for the same elements.

3. Alternative Solutions:

A new house has been completed in Ohio, based on Frank Lloyd Wright's final design, known as Riverrock. Owner and general contractor Sarah Dykstra claims the house stays true to Wright's original plans despite some disagreement from official Wright organizations, which refer to it as an "interpretation" rather than an authentic work.

Dykstra purchased the property in 2018, which included Wright's unbuilt plans. The three-bedroom home features a unique P-shaped design with stone and glass elements, reflecting Wright's style. Construction began in October 2023 and was completed in January 2025, following local building regulations.

While the Dykstra family aimed to maintain the original design's integrity, the Frank Lloyd Wright Foundation noted that the completed house differs from Wright's plans due to modern construction codes and materials. Despite this, Dykstra expresses pride in the project, which is available for rent.

The UK government is developing a "murder prediction" program aimed at identifying individuals who may become violent offenders. This initiative, originally named the "homicide prediction project," uses algorithms to analyze data from thousands of people, including crime victims, to assess risks of serious violence. Critics, including the group Statewatch, have raised concerns that the project could be biased against minority and low-income communities, as it may involve data from individuals who have not committed crimes.

The project is described as being for research purposes only and is meant to improve public safety. However, there are fears that it could reinforce existing biases in the criminal justice system. The Ministry of Justice insists that only data from convicted offenders will be used, while campaigners argue that sensitive information, including mental health and domestic abuse details, could be included.

The project was initiated by the Prime Minister's office and relies on data from various official sources, including the Probation Service and police. A report on the findings of this research will be published in the future.

In New Delhi's Nehru Place, a vibrant repair market is thriving, where technicians like Sushil Prasad are reviving old laptops by combining parts from discarded devices. These "Frankenstein" laptops are affordable alternatives for students and workers, offering functioning technology at a fraction of the cost of new models. For example, a repaired laptop can cost around INR 10,000 ($110) compared to a new one priced at INR 70,000 ($800).

Despite the growing demand for these hybrid devices, the repair industry faces challenges from global tech companies that make repairs difficult by limiting access to spare parts and using proprietary designs. This push for planned obsolescence complicates the work of technicians who often rely on informal e-waste markets, like Seelampur, to source components.

While salvaging e-waste provides cheap materials, it poses health risks for workers handling toxic substances. There is a pressing need for the Indian government to support the repair sector through legislation and better access to parts, which could help reduce e-waste and create jobs. As India's digital economy expands, the importance of affordable technology and the repair ecosystem is becoming increasingly vital.

The author recounts their frustrating experience trying to use Tailwind CSS for a new app while facing technical issues and pressure to keep up with modern technologies.

1. Background: The author, working on a new app, decided to use Tailwind CSS because it's popular in their workplace, despite struggling with its complexities and the need to learn a new syntax.

2. Technical Issues: After returning home and trying to run Tailwind on their powerful Mac Pro, they encountered an "illegal instruction" error due to Tailwind's new version requiring advanced CPU features that their machine lacked. This led to a long, fruitless debugging process.

3. Workaround Attempts: To move forward, they tried using a CDN version of Tailwind but faced issues with CSS classes not displaying correctly due to the preflight reset. Their frustration grew as they spent days troubleshooting without making progress on the app.

4. New Computer: Eventually, the author bought a new Mac Studio M2 to resolve the issues, but they found themselves still struggling with Tailwind. After more time wasted, they decided to remove Tailwind from the app entirely.

5. Reflection on Technology Choices: The author reflects on the pressure to adopt new technologies out of fear of falling behind (FOMO) and critiques the tech influencer culture that pushes developers to use every new tool. They emphasize that using familiar technologies that align with project goals is more important than following trends.

6. Final Thoughts: They conclude that while Tailwind has its benefits, the mental burden of learning new systems and the complications that come with them can overshadow the advantages. The author advocates for focusing on what they know and building without the anxiety of needing to adopt every new tech fad.
