In 2019, Gmail product manager Aakash Shaney noted that email had not significantly changed, despite advancements in web technology. With Google’s AMP for email, emails could become interactive, allowing users to take actions like booking flights or responding to comments directly from their inbox. However, there was skepticism about the necessity of such features, with some users expressing frustration.

AMP (Accelerated Mobile Pages) had previously been introduced to improve mobile web experiences, encouraging developers to create AMP-compatible sites to gain better search rankings. However, this came with concerns about control over content and the creation of separate mobile and desktop versions of sites, which went against the principles of responsive design.

When AMP was introduced to email, it aimed to modernize email interactions but required developers to create multiple versions of each email. Although some companies adopted AMP for email, support for it was limited, and it faced criticism for the effort required versus the benefits provided.

Ultimately, Google decided to discontinue the AMP badge and indicated that using AMP was no longer necessary for certain features. While Google still uses AMP for email internally, the broader initiative has largely faded, and developers have found ways to create interactive emails using standard HTML. The essence of email remains unchanged, with its reliability and simplicity valued by users.

Scientists are amazed by a 1,700-year-old egg found in a wishing well in England, which has remained completely intact and is the oldest unintentionally preserved avian egg ever discovered. This egg, dating back to between 270 and 300 AD, was unearthed along with other artifacts from a Roman settlement. Researchers believe the well was initially used for brewing ale and later became a site for rituals.

The egg is still full of liquid due to the unique anaerobic conditions of the waterlogged soil that prevented decomposition. Scientists plan to analyze the contents of the egg, potentially through DNA testing, to determine the species that laid it, likely a type of chicken, which held cultural significance in Roman rituals.

The preservation of the egg is notable not only for its age but also because it has never been broken, which is rare for such finds. This discovery could provide valuable insights into Roman culture related to rituals and the domestication of animals. The egg will eventually be displayed at London's Natural History Museum after thorough study and conservation.

Summary: Aqua Tofana - The 17th Century Husband Killer

Aqua Tofana was a poison created in the 17th century, primarily used by women in southern Italy to discreetly eliminate their husbands and claim their inheritances. The poison, which was colorless, tasteless, and odorless, was believed to contain arsenic and could mimic common illnesses when administered gradually.

The poison was first developed by an Italian woman named Thofania d'Adamo around 1630. After her arrest and execution in 1633, her assistant, Giulia Tofana, continued the operation in Rome, expanding its reach. Aqua Tofana was often disguised as a healing oil called "Manna of St. Nicholas," allowing it to be kept at home without suspicion.

The poison's effectiveness came from its undetectability; it caused gradual health decline, making victims appear sick without raising alarms. Between the 17th and 18th centuries, Aqua Tofana gained a notorious reputation, allegedly claiming hundreds of lives.

Historian Mike Dash suggests that while some deaths were attributed to Aqua Tofana, many may have been due to natural causes. The fear of poisoning during this period led to numerous scandals, reinforcing societal views of poison as a common method of murder. The legend of Aqua Tofana endures today as a symbol of cunning and undetected crime.

Discord is testing face scanning technology to verify users' ages in the UK and Australia, as part of new online safety laws requiring platforms with adult content to implement strong age verification by July. This move is seen as a sign of a larger trend towards stricter age checks online. Experts believe that facial recognition could be the quickest way to provide proof of age, but privacy advocates warn that such checks might not be effective and could raise privacy concerns.

The age verification process will be a one-time check for users encountering sensitive content or changing their settings. Users can either scan their face or upload an ID, with assurances that this information will not be stored. Discord follows similar practices recently adopted by Instagram.

Privacy campaigners argue that age verification technology has limitations and potential risks, including security breaches and digital exclusion. Meanwhile, industry representatives believe there are various methods to verify age while protecting privacy.

In Australia, plans are underway to ban social media for users under 16, as many young children already access platforms meant for older teens. Additionally, New Jersey's attorney general is suing Discord for allegedly misleading parents about safety controls on the app.

As the need for efficient and low-power computing in small devices increases, traditional methods struggle with complex tasks. Stochastic computing (SC) offers a solution by using simple operations on random bit streams to approximate complicated calculations. While SC is naturally fault-tolerant, its accuracy relies on the quality of these bit streams, which are generated by power-hungry devices that take up a lot of space.

Current SC methods usually focus on improving the logic used but overlook the high costs of transferring bit streams between memory and processors. This study proposes using new ReRAM technology to optimize the entire SC process, including generating random numbers, performing SC operations, and converting results back to standard binary format.

Despite ReRAM's lower reliability, SC can handle errors well. The results show that this approach significantly enhances processing speed (1.39 to 2.16 times faster) and reduces energy use (1.15 to 2.8 times less) compared to existing solutions, with only a small drop in image quality (about 5%) across various tasks.

Key points about Zig's GPU capabilities:

• SPIR-V Support: Zig has a mature SPIR-V backend that can generate code for Vulkan and OpenCL.
• PTX and AMDGCN: Zig can also produce native binaries for NVIDIA and AMD GPUs.
• Vulkan vs. OpenCL: OpenCL has more guaranteed features, making it easier for certain operations compared to Vulkan.
• Challenges: One major issue is the need to specify address spaces for pointers, which can complicate the coding process.

Future goals for Zig's GPU development include improving error handling, increasing compatibility with behavior tests, and expanding the standard library with common GPU algorithms.

A new trend has emerged where people use ChatGPT, specifically the new models o3 and o4-mini, to identify locations in photos. These models can analyze images by cropping, rotating, and zooming in, which helps them figure out cities, landmarks, and even specific restaurants. Users have been sharing examples on social media, showing how effective these models are at guessing locations.

However, this raises privacy concerns, as someone could use ChatGPT to deduce personal information from images, such as those shared on social media. While earlier models could also guess locations, the new models have shown improved performance, sometimes identifying places more accurately.

Despite their capabilities, o3 and o4-mini are not perfect and can make mistakes. There are also worries about the lack of safeguards to prevent misuse, such as identifying private individuals in images. OpenAI has stated that they are working on measures to protect privacy and monitor for misuse, but the issue remains significant.

Summary of MCP Run Python

MCP Run Python is a server that allows you to run Python code safely in a controlled environment, using a tool called Pyodide within Deno. This setup keeps the code separate from the main operating system.

To set it up, you need to have Deno installed and run the server with specific commands that give it access to the internet and your local files. The server can operate in two modes:

1. Stdio - for running locally as a subprocess.
2. SSE - for running as an HTTP server, allowing local and remote connections.

You can also use a "warmup" option to prepare the server by downloading necessary Python libraries and checking if everything is functioning correctly.

Here’s a simple example of how to use it with PydanticAI to calculate the number of days between two dates. You create a server instance, set up an agent, and run a query to get the result.

The article discusses how adipose (fat) tissue retains an "obesogenic memory" even after significant weight loss. This memory makes it difficult for individuals to maintain their weight loss and can lead to rapid weight regain, often referred to as the "yo-yo" effect. The authors used advanced RNA sequencing techniques to show that fat cells in both humans and mice have lasting changes in gene expression after weight loss, which can negatively impact their function and response to diet.

Key findings include:

• Obesogenic Memory: Both human and mouse adipose tissues show persistent changes in gene expression linked to previous obesity, even after substantial weight loss.
• Epigenetic Changes: The study suggests that stable epigenetic changes in fat cells contribute to this memory, influencing how these cells behave when exposed to high-fat diets in the future.
• Research Implications: Understanding these memory mechanisms could help in developing better strategies for long-term weight management and improving health outcomes for those who struggle with obesity.

Overall, the research highlights the challenges in maintaining weight loss due to underlying biological processes that support weight regain.

Recent headlines have sparked interest in the possibility of extraterrestrial life, triggered by a paper titled "New Constraints on DMS and DMDS in the Atmosphere of K2-18 b from JWST MIRI." The paper discusses two sulfur-containing molecules, dimethyl sulfide (DMS) and dimethyl disulfide (DMDS), which are often associated with marine life on Earth.

K2-18 is a red dwarf star located in the constellation Leo, with a planet called K2-18b that is larger than Earth but less dense, making it a candidate for a "Hycean planet," which could have liquid water. The planet was discovered in 2015 by observing its transit across the star, allowing scientists to analyze its atmosphere.

The paper reports unexpected findings from the James Webb Space Telescope, indicating high levels of DMS and DMDS in the planet's atmosphere. On Earth, these compounds are primarily produced by phytoplankton, suggesting a potential link to life. However, the presence of these molecules does not confirm life, as they could arise from unknown chemical processes on K2-18b.

Further investigation is needed to understand the planet's atmosphere and the production of these compounds. Researchers suggest conducting experiments on Earth to explore alternative ways DMS and DMDS could form, as well as gathering more data from K2-18b. The findings open the door to exciting possibilities about life beyond Earth, but more research is essential to draw any conclusions.

The author is frustrated with DNS registrars, particularly Namecheap, for not understanding how DNS works, despite it being their main responsibility. They manage a small IRC network and utilize Let's Encrypt for TLS certificates. The author has a CAA record that currently allows any Let's Encrypt account to issue certificates for their domain, which is risky. They want to modify this record to restrict it to specific accounts using new parameters from a recent RFC (Request for Comments) standard.

When they attempt to update the CAA records in Namecheap's interface, they encounter errors. After reaching out to Namecheap support, they receive unhelpful replies that misunderstand the issue and the technical specifications involved. Despite providing detailed explanations and references to relevant standards, Namecheap continues to offer generic advice and suggests contacting them for SSL purchases, which frustrates the author further.

In contrast, they successfully updated CAA records for another domain at a different registrar, highlighting Namecheap's shortcomings.

The Wall of Sheep is a well-known exhibit at DEF CON where participants try to catch people logging into unencrypted websites on a public Wi-Fi network. When they do, they display the captured usernames and passwords on a large screen, serving as a reminder to be cautious online.

A participant wondered if it was possible to hack the Wall itself and inject their own content. They made some assumptions about how the Wall operates, particularly that it could be vulnerable to Cross Site Scripting (XSS) attacks. This participant planned to inject JavaScript into the login field, believing it could display their custom message.

To execute the plan, they set up a web server and attempted to capture login credentials while connected to the DEF CON Wi-Fi. However, they faced challenges, including using their personal device and not being able to get the captured credentials displayed on the Wall.

They enlisted help from other attendees, Jan and Pat, but ultimately found out that a moderator, referred to as a "Shepherd," would manually input the credentials to display them on the Wall, which defeated their automated approach.

In the end, the attempt was unsuccessful, but the participant plans to try again next year with better preparation, including using a different authentication method and bringing a burner device. They are determined to learn from this experience and improve their chances of success.

The article by Oona Räisänen explores the sounds made by passing planes and helicopters, specifically the 'whoosh' sound often attributed to the Doppler effect. However, the author finds that this explanation alone doesn't fully account for what we hear.

Key points include:

1. Doppler Effect Misunderstanding: While the Doppler effect explains the change in pitch as a plane passes, it doesn't account for the unique 'whoosh' sound that occurs.

2. Comb Filtering: The whoosh is related to a phenomenon called comb filtering, which happens when two copies of the same sound arrive at different times and interfere with each other, creating peaks and valleys in the sound spectrum.

3. Cepstrum Analysis: Analyzing the sound in the cepstral domain reveals a sweeping peak that correlates with the pitch changes we hear, suggesting a delayed echo.

4. Echo from the Ground: The 'whoosh' may result from the direct sound of the plane and a delayed echo from the ground. The time difference between these sounds aligns with the observed pitch changes.

5. Everyday Examples: The whoosh effect can also be experienced with other sounds, like waterfalls or traffic noises, when they reflect off nearby surfaces.

The author encourages readers to observe and experiment with the whoosh effect themselves, highlighting its presence in various environments and situations.

In this text, the author discusses advanced implementations of SQL virtual tables in Go, focusing on how to support write operations and transactional behavior in SQLite.

Key Points:

1. Writable Virtual Tables: By implementing xUpdate, you can create virtual tables that allow data to be written, requiring specific hooks for transaction management:

   • xBegin: Starts a transaction.
   • xSync: Prepares for a commit; failures abort the transaction.
   • xCommit: Finalizes the transaction.
   • xRollback: Reverts changes if needed.

2. SQLite Transaction Basics: SQLite uses a rollback journal to ensure atomicity, meaning if an error occurs, it can restore the original data. For multiple databases, a super-journal is used to coordinate commits.

3. Two-Phase Commit: SQLite's commit process is divided into two phases:

   • Phase One (xSync): Ensures all data is written to disk. If any xSync fails, the transaction rolls back.
   • Phase Two (Cleanup): Cleans up journal files after ensuring data durability.

4. Error Handling: Errors in the cleanup phase (xCommit and xRollback) are ignored since the integrity of the transaction is already guaranteed.

5. Guidelines for Virtual-Table Authors:

   • Ensure durability in xSync.
   • Keep xCommit and xRollback simple and idempotent, only performing cleanup tasks.

Overall, the author explains how to implement and manage writable virtual tables in SQLite, ensuring they work correctly within the transaction system.

The essay "AI as Normal Technology" by Arvind Narayanan and Sayash Kapoor presents a perspective on artificial intelligence (AI) that contrasts with more extreme views of AI as a superintelligent entity. Instead, the authors argue that AI should be seen as a "normal technology," similar to electricity or the internet. This view emphasizes that while AI can have significant impacts, it is ultimately a tool under human control.

Key points include:

1. AI as a Tool: AI should be viewed as a technology that we can manage, rather than as a human-like intelligence. This perspective suggests that drastic changes or policies are not necessary to control AI.

2. Slow Progress: The authors predict that the societal impacts of AI will unfold slowly over decades, distinguishing between AI methods (the technology itself), applications (how it is used), and adoption (how widely it is accepted). These aspects evolve at different rates.

3. Human-AI Collaboration: In a future with advanced AI, humans will still retain control and oversight, with AI assisting in various tasks rather than completely replacing human roles.

4. AI Risks: Viewing AI as normal technology changes how we understand risks associated with it, such as misuse or accidents. The authors argue that this perspective leads to different strategies for managing these risks.

5. Policy Implications: The authors advocate for policies that reduce uncertainty and promote resilience rather than drastic measures based on fears of uncontrollable superintelligent AI. They warn that overregulation could hinder the beneficial use of AI.

6. Historical Context: The authors draw parallels with past technological revolutions, noting that societal adaptation to new technologies like electricity took time and required significant changes in processes and structures.

In summary, the essay emphasizes a balanced view of AI, advocating for responsible management and gradual adaptation rather than alarmist or utopian expectations.

The text discusses the author's experience with implementing a library for working with iCalendar files, focusing primarily on handling recurring events. Here are the key points simplified:

1. iCalendar Format: iCalendar is a standard format (established in 1998) used for sharing calendar data, such as event details and RSVP notifications.

2. Recurring Events: Recurring events can be complex, with various rules for how often they repeat (e.g., daily, weekly, specific days of the month). The author emphasizes the challenge of defining these rules clearly.

3. Implementation Approach: The author proposes using a "distance function" to determine when events occur instead of relying on complex conditional logic. This function would return zero when a date matches an event occurrence or a positive span indicating how far off the next occurrence is.

4. Distance Functions: Similar to signed distance functions used in graphics, these functions can simplify the implementation of recurrence rules by allowing for efficient computation of when an event happens without needing to hard-code every possible combination of rules.

5. Optimization: The author discusses optimization strategies for the algorithm to avoid unnecessary computations while ensuring correctness. This includes using SQL-like queries to better understand and implement the recurrence logic.

6. Concrete Examples: Various examples illustrate how to handle specific rules related to days of the week and month, and how to combine them effectively. The approach allows for clear and logical handling of complex recurrence rules.

7. Final Thoughts: The author believes this distance-based method is simpler and faster than traditional implementations, and although it may not be completely original, it offers a fresh perspective on the problem.

The article ultimately highlights a novel approach to managing complex calendar data while maintaining efficiency and clarity in the code.

Summary: Oda Ujiharu - The Admired 'Weakest Samurai Warlord'

Oda Ujiharu, a lesser-known figure from Japan's Sengoku period, is often labeled as the "weakest samurai warlord" due to his frequent losses. He ruled Oda Castle in Hitachi Province and faced multiple defeats, with his castle changing hands nine times. However, his resilience in reclaiming it eight times, despite smaller armies, earned him the nickname "The Phoenix."

Ujiharu’s leadership was marked by poor military decisions, such as ignoring advice from his chief strategist. Despite these mistakes, he was admired for his loyalty to his people, often risking confrontations to prevent sieges that would harm his subjects. His retainers remained loyal, viewing him favorably even with his failures.

Though Ujiharu made strategic errors, like betraying powerful allies, he demonstrated diplomatic skills by forming alliances for his benefit. Ultimately, he lost his titles after refusing to pledge allegiance to Toyotomi Hideyoshi but was spared his life. His story highlights the complexity of leadership and the admiration that can arise from perseverance and loyalty, despite failures.

This article discusses the troubled development of King's Quest: Mask of Eternity, the eighth installment in the King's Quest series, and the corporate scandal involving Sierra On-Line's parent company, CUC, which merged with HFS to form Cendant.

Key points include:

1. Background of Development: Roberta Williams, the game's creator, struggled with development after her husband, Ken Williams, left Sierra. The project faced delays and was influenced by the changing gaming landscape, pushing it to adopt a real-time 3D engine and include action elements, diverging from the traditional point-and-click format.

2. Corporate Changes and Challenges: Sierra was acquired by CUC, leading to a lack of clear direction and authority in game development. Roberta found her creative control diminishing, and the new corporate environment demanded changes that she wasn't equipped to handle.

3. The CUC Scandal: CUC was involved in widespread accounting fraud, overstating revenues to maintain stock prices. When Cendant was formed from the merger, significant discrepancies in financial reports were uncovered, leading to a major scandal that affected the company's reputation and stock.

4. Game Release and Reception: Mask of Eternity was finally released in late 1998 but was poorly received. It failed to resonate with both longtime fans of the series and new players, leading to its commercial failure and marking the end of the King's Quest franchise.

5. Aftermath: Walter Forbes, CUC's CEO, faced legal consequences for his role in the fraud, while Henry Silverman worked to stabilize Cendant post-merger. Sierra's legacy was impacted, and Roberta Williams stepped away from game design for many years.

Overall, the article highlights the intersection of creative struggles in game development with corporate malfeasance, ultimately leading to the decline of a once-popular gaming franchise.

The article argues that the new tariffs on imports announced by the U.S. president will not succeed in bringing manufacturing back to America and may actually harm the economy. Here are the key points:

1. Tariffs Are Insufficient: The tariffs, ranging from 10% to 49%, are not high enough to offset the lower production costs in countries like China. Manufacturing in the U.S. remains more expensive, even with tariffs.

2. Weak Supply Chain: The U.S. lacks a strong industrial supply chain, which complicates manufacturing. Most components for products like iPhones are produced in Asia, making it cheaper to assemble products there.

3. Lack of Knowledge and Skills: Many manufacturing skills have been lost in the U.S., making it difficult to produce complex components domestically.

4. Labor Force Issues: American workers may not have the necessary skills or work ethic compared to their foreign counterparts, particularly in manufacturing.

5. Infrastructure Problems: The U.S. lacks the necessary infrastructure, like stable electricity and efficient transportation, to support a manufacturing revival.

6. Time and Investment: Building new factories takes a long time, and businesses are hesitant to invest due to uncertainty around tariff policies.

7. Economic Impact: The tariffs could freeze business activity and lead to a recession, as companies struggle with rising costs and unpredictable regulations.

8. Policy Flaws: The way tariffs are structured could hurt American manufacturers more than foreign competitors. Tariffs on components needed for manufacturing and machinery increase costs for U.S. producers.

9. Globalization Effects: Instead of bringing jobs back to the U.S., tariffs may shift production to other countries like Vietnam.

10. Need for Comprehensive Reform: To successfully bring manufacturing back, the U.S. must address fundamental issues like education, healthcare, and social stability, while also creating a favorable business environment.

The author concludes that without significant changes, the current policy could damage the U.S. economy rather than enhance it.

Summary of "The Second Half"

We are at a pivotal moment in AI development, referred to as "AI's halftime." The first half of AI focused on creating new training methods and models, leading to significant achievements like beating world champions in games and excelling in academic tests. The breakthroughs were primarily about improving training techniques, such as deep reinforcement learning (RL) and scaling.

The key change now is that RL is finally effective and generalizes across various tasks, such as software engineering, creative writing, and complex problem-solving. This means we can use a single approach to tackle diverse challenges, which was previously thought impossible.

As we move into the second half of AI, the focus will shift from merely solving problems to defining what problems we should solve and how to measure progress effectively. This requires a new mindset, similar to that of a product manager.

In the first half, impactful AI research centered on developing new models and methods, often overshadowing the importance of benchmarks and evaluation. As models improved, they quickly surpassed existing benchmarks, leading to a cycle of creating progressively harder benchmarks.

However, this cycle is now breaking down. The new "recipe" for AI development includes language pre-training, scale, and reasoning, which combine to create effective models. This shift suggests that the emphasis should move from just improving algorithms to redefining evaluation methods to ensure real-world utility.

In summary, the second half of AI will involve:

• Developing novel evaluation setups that reflect real-world challenges.
• Using the established recipe or enhancing it with new components to solve these challenges. This transition promises to create significant economic value by producing useful AI applications, moving beyond the incremental improvements of the first half.

Sure! However, I need the text you want summarized. Please provide it, and I'll create a simplified summary for you.

Summary of Differentiable Programming from Scratch

Differentiable programming is an important area of research, especially relevant to machine learning and fields like computer graphics. It allows for solving optimization problems using techniques like gradient descent.

Key Concepts:

1. Differentiation: The derivative measures how a function changes as its input changes. In one dimension, it provides the slope of the function. In higher dimensions, it can be understood as a map that relates input vectors to output vectors.

2. Gradient: The gradient is a vector that indicates the direction of the steepest ascent of a function. It combines partial derivatives, showing how the function changes with respect to multiple inputs.

3. Directional Derivative: This generalizes the concept of partial derivatives to compute the rate of change of a function in any given direction.

4. Jacobian: For functions with multiple outputs, the Jacobian matrix contains all first-order partial derivatives, allowing us to understand how changes in inputs affect multiple outputs.

5. Chain Rule: This principle helps in computing the derivative of composed functions, crucial for optimizing functions through gradient descent.

6. Optimization and Gradient Descent: This is a method to find the minimum of a function by iteratively moving in the direction of the negative gradient. The process involves choosing a starting point, calculating gradients, and updating the point until a minimum is found.

7. Differentiating Code: To differentiate complex programs (like neural networks), we use automatic differentiation (autodiff). This can be done through:

   • Numerical Differentiation: Approximates derivatives but can be inefficient for high dimensions.

   • Symbolic Differentiation: Transforms code into a differentiable form but can lead to large representations.

   • Automatic Differentiation: Combines the efficiency of numerical and symbolic methods, using techniques like forward mode and backward mode.

   • Forward Mode computes derivatives for single input directions efficiently.

   • Backward Mode computes gradients for functions with many inputs and one output in a single pass, which is suitable for neural networks.

8. Practical Application: The article provides an example of using differentiable programming to de-blur images by minimizing a loss function that measures the difference between blurred guesses and observed images.

For more details, numerous resources on JAX, PyTorch, TensorFlow, and other frameworks are recommended for further exploration into differentiable programming techniques and applications.

In his article, Jason Cohen discusses the critical distinction between what can and cannot be solved with money in a startup.

Key points include:

1. Team Building: Attracting talented individuals is very challenging and cannot be accomplished with money alone. While money can help once you have a team, it won't help you find great people initially.

2. Marketing: Money can buy advertising and campaigns, but it cannot buy genuine authority or respect in social media and blogging. Successful marketing often requires authentic engagement rather than just spending.

3. Execution vs. Exploration: Money helps with execution (like writing code or gaining leads) but cannot replace the knowledge, creativity, and understanding needed for exploration and innovation.

4. Raising Money: To attract investors, demonstrate how money will improve broken aspects of your business and showcase your ability to master areas that money cannot solve. Be prepared to discuss your plans and how you adapt based on customer feedback.

5. Skills Over Platitudes: Instead of merely claiming adaptability, provide concrete examples of how you've learned and improved, showing your ability to think critically and navigate challenges.

Overall, the article emphasizes that the most valuable assets in a startup are the skills, knowledge, and creativity that money cannot buy.

The article by Tony Bradley discusses the silence of the cybersecurity industry in response to an Executive Order targeting Chris Krebs, the former director of the Cybersecurity and Infrastructure Security Agency (CISA). Krebs, who confirmed the integrity of the 2020 election, was fired for upholding the truth amidst widespread misinformation. The industry’s lack of support for Krebs is seen as a failure to defend core values of truth and integrity.

Key points include:

1. Krebs's Role: As Trump's appointee, Krebs worked to secure the 2020 election against cyber threats. His assessment that the election was secure was backed by courts and audits.

2. Executive Order Issues: The order aimed at Krebs raises constitutional concerns, as it appears to punish him for his protected speech, undermining the separation of powers.

3. Industry Silence: The cybersecurity community, instead of rallying in support of Krebs, has mostly remained quiet, which is viewed as a failure to stand against injustice.

4. Moral Responsibility: The article emphasizes the need for the cybersecurity industry to defend principles and truth, warning that silence in the face of authoritarianism enables it.

5. Broader Implications: This situation is not just about one person; it reflects the industry's commitment to democracy and the rule of law. The author calls on cybersecurity leaders to speak out and uphold their values.

In summary, the article criticizes the cybersecurity industry's silence regarding the targeting of Krebs and stresses the importance of standing up for truth and integrity, especially during challenging times.

Ege Erdil and Tamay Besiroglu, co-founders of Mechanize, discuss their views on artificial general intelligence (AGI) and its implications for the economy. They argue that AGI is still about 30 years away, with some significant milestones expected around 2045. They believe that the concept of an "intelligence explosion"—where AI rapidly improves itself—may be misleading, as they see a variety of factors beyond intelligence that contribute to technological and economic growth.

The duo emphasizes that while AI has made impressive advancements, especially in reasoning and coding, it is still far from being capable of fully automating remote work tasks. They think that AI models currently lack the necessary competencies to handle complex, real-world problems that require long-term planning and creativity. They argue that future improvements will depend not just on scaling up AI capabilities but on addressing various complementary innovations.

Erdil and Besiroglu challenge the notion that simply automating parts of the research and development cycle will lead to AGI. They believe that true intelligence encompasses more than just coding ability and that current AI models do not possess the breadth of understanding or creativity that humans do. They also express skepticism about the idea that an AI's economic value directly correlates with its transformative potential.

In summary, while they acknowledge rapid progress in AI, they stress that achieving AGI is still a complex challenge that requires significant advancements in various areas beyond just intelligence.

CVE Foundation Launch Announcement

On April 16, 2025, the CVE Foundation was officially established to ensure the future stability and independence of the Common Vulnerabilities and Exposures (CVE) Program, which has been vital to global cybersecurity for 25 years.

Previously, the CVE Program was funded by the U.S. government, but concerns arose about its sustainability being tied to a single government sponsor. This concern intensified when MITRE informed the CVE Board that the U.S. government would not renew its management contract.

In response, CVE Board members have worked over the past year to create a non-profit foundation dedicated to the mission of maintaining high-quality vulnerability data for cybersecurity professionals worldwide. The CVE Foundation aims to eliminate risks associated with a single point of failure in vulnerability management and to ensure that CVE remains a trusted, community-driven resource.

The Foundation will soon share more details about its structure and how the community can get involved. For further information, contact [email protected].

The author switched from Spotify to Jellyfin after struggling with various music players. Initially, they gathered their music files but found that most players were outdated and difficult to use. They tried several options, including VLC and foobar2000, but none met their needs.

They even built a simple web player, but it failed during travel when offline access was needed. Eventually, they settled on Apple Music, which worked well but had storage issues.

A YouTube video by Jeff Geerling introduced them to Jellyfin, a self-hosted media server that could replace Spotify. Despite the challenges of self-hosting, the author found it easy to set up on a spare computer and discovered apps that allowed offline listening. They are now enjoying Jellyfin and have started self-hosting other applications, like Immich for photo storage.

The author encourages others to try self-hosting, as it offers greater control over personal media and can be a rewarding hobby. They believe that with continued improvements in open-source software, users can eventually access their media without relying on external services.

OpenAI is in discussions to buy an AI coding startup called Windsurf for around $3 billion. Additionally, Adobe has invested in Synthesia, a company that creates AI-generated video clones for corporate use. OpenAI has also announced that its latest AI model can understand images, including diagrams and sketches.

BitNet b1.58 2B4T is the first open-source 1-bit Large Language Model with 2 billion parameters. It was trained on 4 trillion tokens and has been tested for language understanding, math skills, coding, and conversation. The model performs as well as other similar-sized LLMs but is more efficient in terms of memory use, energy, and speed. Its model weights are available on Hugging Face, along with open-source tools for running it on both GPU and CPU.

Summary of "Size Matter"

In modern computing, machines often have hundreds of GB of RAM, which can significantly improve PostgreSQL performance. However, how PostgreSQL manages memory, particularly the shared buffer, can be surprising.

Key Points:

1. Shared Buffer Function: The shared buffer is a memory segment in PostgreSQL that stores data pages being read or modified. It helps manage data flow between the database and its backends.

2. Buffer Replacement Challenges: When the shared buffer is full, PostgreSQL needs to evict certain buffers to make room for new data. The original method (used in PostgreSQL 7.4) was a simple last recently used (LRU) algorithm, which had limitations. This was later replaced by more complex methods, including the current "clock sweep" algorithm.

3. Clock Sweep Algorithm: This algorithm uses a circular buffer to track which buffers are candidates for eviction. It checks if a buffer is in use or if it needs to be written to disk before recycling. If the free list (which holds available buffers) is empty, it must scan through the entire shared buffer to find an evictable buffer.

4. Ring Buffer for Bulk Operations: Certain operations, like VACUUM or large data scans, temporarily use a smaller ring buffer, which helps maintain performance without affecting the entire shared buffer.

5. Setting Shared Buffer Size: PostgreSQL recommends setting the shared buffer to about 25% of the system's RAM, but this can be tricky on systems with less than 4 GB of RAM. For larger systems, careful sizing is crucial, especially if the data area exceeds the shared buffer size.

6. Performance Considerations: A well-sized shared buffer can improve performance, but if it becomes too full and requires frequent scanning, it can slow down operations. Generally, keeping the shared buffer under 64 GB is advised to prevent regression in performance.

In conclusion, configuring PostgreSQL's shared buffer correctly is vital for optimal performance. The default settings are conservative and should be adjusted based on the system's RAM and workload.

The Common Vulnerabilities and Exposures (CVE) program, which tracks security issues in tech products, is facing uncertainty after the U.S. government initially cut funding for MITRE, the organization that runs it. Although funding has been extended for another 11 months, the European Union is developing its own system called the European Union Vulnerability Database (EUVD) to track security bugs.

The EUVD will operate similarly to the U.S. National Vulnerability Database (NVD) but will also use its own identifiers alongside the CVE IDs. This shift comes amidst concerns about the reliability of the CVE program, leading to fears of a fragmented system where the U.S. and Europe may have separate databases. Experts warn that this could lead to confusion and inconsistency in vulnerability tracking.

Some believe the EUVD could lead to a more sustainable and unbiased system, as it aims to have multi-national support. In contrast, reliance on U.S. government funding for the CVE program raises concerns about impartiality. The situation highlights the importance of having a unified system for identifying vulnerabilities to ensure clear communication across industries and nations.
