SQLite's Write-Ahead Logging (WAL) mode, introduced in 2010 for better write performance, has a checksum feature. However, it has a significant flaw: if a checksum error occurs, SQLite silently drops the corrupted frame and all subsequent frames without raising an error, potentially leading to data loss.

Key points:

• WAL Mode: In WAL mode, new writes are stored in a WAL file, which is then checkpointed to the main database. Each piece of data in this file is called a frame, and frames have checksums for validation.
• Checksum Mechanism: The checksums are rolling, meaning each frame's checksum depends on the previous one. If any frame has a checksum mismatch, all subsequent frames are discarded.
• Recovery Process: During recovery, SQLite checks the WAL frames sequentially. If a checksum fails, the process stops, and all following frames are lost.
• Common Causes of Issues: Problems can arise from missing WAL index files or unclean shutdowns during write operations.
• Concerns: The author expresses dissatisfaction with SQLite's failure to notify users of corruption and suggests it would be better to throw an error and allow users to handle the issue. The current behavior may stem from backward compatibility or a focus on embedded environments where stability is prioritized over strict error handling.

Overall, the author believes SQLite's handling of corruption is flawed and may lead to unnecessary data loss.

The article discusses the relationship between memory safety and thread safety in programming languages, particularly focusing on Go.

Key points include:

1. Memory Safety Explained: Memory safety generally means preventing issues like use-after-free and out-of-bounds memory access. However, the author argues that this definition is not sufficient without considering thread safety.

2. Undefined Behavior (UB): The main concern is that a program should not exhibit Undefined Behavior, which can lead to vulnerabilities. The author asserts that breaking memory safety can occur through data races, making a language like Go not truly memory safe.

3. Example in Go: The author provides an example illustrating how a Go program can crash due to data races, despite Go being labeled as memory safe. This highlights that Go does not ensure safety when concurrent modifications occur.

4. Comparison with Other Languages: Other languages like Java have strong concurrency models that prevent memory corruption, even with data races, whereas Go lacks such robust safeguards.

5. Language Trade-offs: The article discusses the trade-offs languages make between safety and performance. Go's design prioritizes simplicity but can lead to subtle bugs that compromise safety.

6. Conclusion: The author emphasizes the importance of understanding the safety guarantees of programming languages. They argue that a clear distinction between safe and unsafe languages should be made based on the possibility of UB, rather than further subclassifying types of safety.

Overall, the article calls for a better understanding of how different languages handle memory and concurrency issues, particularly highlighting Go's vulnerabilities.

The text discusses a simple but effective programming technique that improves code quality by using specific types for different values instead of generic types like integers or strings. This approach helps prevent bugs that arise when values are mixed up, such as using a user ID as an account ID.

Key points include:

1. Defining Custom Types: Instead of using generic types directly (like UUIDs), create specific types for different entities (e.g., AccountID and UserID). This adds context and reduces errors.

2. Example of Type Safety: The author provides an example where using custom types prevents accidental misuse, such as attempting to pass an AccountID where a UserID is expected. The type system catches these mistakes at compile time, unlike using generic types.

3. Library Example: The author mentions a library called libwx that uses specific types for various measurements, preventing common errors when converting between units.

4. Conclusion: The type system should be utilized to enhance code safety. By defining distinct types for different models and avoiding the use of plain integers or strings, developers can significantly reduce bugs.

Overall, the message is clear: leverage your programming language's type system to create safer and more reliable code.

The editorial discusses the importance of human-generated scientific writing, especially in the context of large-language models (LLMs), which can quickly produce text. Writing is essential not just for reporting research but also for organizing thoughts and uncovering new ideas. It helps researchers clarify their main messages and enhances learning and memory.

While LLMs can assist with tasks like improving grammar and summarizing literature, they cannot replace the creative process of writing. They lack accountability and can produce incorrect information, requiring careful verification. Thus, relying entirely on LLMs may hinder the reflective and narrative aspects of research writing, which are crucial for effective communication in science. The piece calls for a continued appreciation of the value of human writing in research.

This article discusses online privacy and security, focusing on how websites track users through techniques like cookies and web fingerprinting.

1. Tracking Basics: Websites can see what pages you visit and may know your identity if you're logged in. Cookies are small files that help websites remember you, but third-party cookies can track your activity across multiple sites.

2. Browser Protections: Browsers like Firefox have started to protect users by isolating third-party cookies, making it harder for advertisers to track you across different sites. Private Browsing modes can clear cookies and history, but these measures aren't foolproof.

3. Web Fingerprinting: This is a more advanced method of tracking that doesn't rely on cookies. It collects data about your browser and device (like screen size and operating system) to create a unique ID. This can identify users even in Private Browsing mode.

4. Fingerprinting Services: Companies like FingerprintJS provide services for websites to track users via fingerprinting. They can create a unique ID that persists even if you clear your browser data.

5. Testing Fingerprinting: The article describes tests showing how FingerprintJS can link sessions across different browsers. Firefox can resist fingerprinting with specific settings, while Chromium and Chrome are more vulnerable. Tor Browser is the most secure option against fingerprinting.

6. Recommendations: For maximum privacy, use Tor Browser or Firefox with the resistFingerprinting setting enabled. Chromium users might consider the Brave browser, though it still relies on Chromium technology. VPNs do not protect against fingerprinting as they only hide your IP address.

In summary, while you can take steps to protect your online privacy, tracking via fingerprinting poses significant challenges that current privacy measures may not fully address.

Summary: How Distillation Makes AI Models Smaller and Cheaper

Distillation is a technique in artificial intelligence (AI) that allows researchers to create smaller and more cost-effective models by training them using larger, more complex models known as "teacher" models. This process, which has been researched since around 2015, helps companies reduce the resources needed to run AI models while maintaining their performance.

The concept was introduced by Google researchers, including Geoffrey Hinton, who aimed to improve the efficiency of machine-learning models. Instead of penalizing all errors equally, distillation allows a smaller "student" model to learn from the more nuanced outputs of a larger model, which provides valuable insights into the similarities and differences between categories.

Distillation gained popularity as AI models grew in size and complexity, leading to increased operational costs. Companies like Google and OpenAI began using it widely, producing smaller versions of large models, such as DistilBERT.

While distillation typically requires access to the teacher model, it can also be done through interactions that allow the student model to learn from the teacher without direct access. Recent developments have shown that distillation can also be effective for training models capable of complex reasoning.

Overall, distillation is now considered a fundamental technique in AI, enabling the creation of efficient models with lower costs and resource requirements.

A privacy flaw has been discovered in Jitsi, a popular open-source web conferencing platform. This flaw allows an attacker to secretly access a user's microphone and camera without their consent.

Here's how it works: An attacker can create a meeting on Jitsi and trick users into clicking a link that redirects them to this meeting. If users have previously granted permission for Jitsi to access their audio and video, the attacker's meeting can run in the background, capturing audio and video without the user knowing.

Jitsi claims this capability is a feature and has no plans to fix it, which raises concerns about user security. The flaw was reported on June 17, 2025, but the response from Jitsi has been minimal. The author believes this is a significant risk, especially on public instances of the platform.

The author argues that the current approach to building AI tools is flawed and counterproductive. Instead of enhancing human capabilities, these tools often deskill users by taking over tasks that humans excel at, like collaborative learning and problem-solving.

Key points include:

1. How Humans Learn: Effective learning involves retrieving information, understanding processes rather than just memorizing facts, and collaborating with others. Humans learn best through cumulative iteration in groups rather than as solo innovators.

2. AI Tooling Issues: Most AI tools operate by automating tasks instead of supporting human thought processes. This leads to a decline in human skills and a feedback loop where both humans and AI become less effective.

3. Proposed Improvements: AI should act as an “absent-minded instructor” to guide users through processes, encouraging them to think and learn, rather than just providing answers. Tools should help users recall processes, demonstrate actions, guide them through challenges, and suggest enhancements based on their input.

4. Building a Better AI: The ideal AI tools should reinforce human learning and collaboration, enhance problem-solving abilities, and encourage a cycle of continuous improvement. This approach prioritizes human-driven processes and collective knowledge transfer.

5. Conclusion: The author emphasizes the need to shift the focus back to human capabilities in AI tool design, ensuring that these systems support rather than replace human learning and collaboration. By doing so, we can create a positive feedback loop that benefits both humans and AI.

Summary of "Shattering the Rotation Illusion: How Quickly Leaked AWS Keys are Exploited"

This report discusses the dangers of leaked AWS Access Keys and how attackers exploit them quickly, often within minutes of exposure. The series explored various platforms where keys can be leaked, such as GitHub, GitLab, and developer forums, revealing that traditional security measures like automatic key quarantine are inadequate.

Key points include:

1. Exploitation Speed: Attackers can utilize exposed keys almost immediately, performing tasks like data extraction, privilege escalation, and causing financial harm through service abuse.

2. Misconceptions about Quarantine: While platforms like GitHub quarantine exposed keys, this does not prevent attackers from exploiting them due to remaining accessible permissions.

3. Lack of Immediate Disablement: AWS's recommendation to delete exposed keys lacks a mechanism to automatically disable them upon detection, which leaves organizations vulnerable. In contrast, Google Cloud automatically revokes compromised keys, providing better protection.

4. Attacker Tactics: Attackers operate systematically and utilize automation. They gather information about environments and can cause significant disruptions and data loss.

5. Need for Stronger Security Measures: The report argues for moving away from reliance on secret rotation and towards modern strategies like Zero Trust and ephemeral identities that focus on proactive threat containment.

6. Introduction of AWSKeyLockdown: A new tool, AWSKeyLockdown, has been developed to revoke compromised AWS access keys instantly, minimizing the time attackers have to exploit them.

The report concludes with a call to action for organizations to rethink their security strategies in light of these findings to better protect against the risks of exposed secrets.

The article discusses the author's experience using GrapheneOS, a privacy-focused operating system for Google Pixel phones. Recently, law enforcement in Spain has associated Google Pixels with crime, particularly because some criminals prefer GrapheneOS for its security features. The author finds this connection troubling and emphasizes that their use of GrapheneOS is not linked to illegal activities but rather to the desire for control over personal data.

Key points include:

• GrapheneOS enhances privacy and security by limiting access to personal data and allowing users to control app permissions more granularly than the standard Android OS.
• Users can install the Play Store and most apps without losing functionality, which is often a concern with custom operating systems.
• The operating system has features like a duress PIN, which can delete all data on the phone if the user is coerced into revealing their password.
• The author argues that privacy tools like GrapheneOS should not be stigmatized or seen as suspicious simply because they can be used by criminals.
• The article highlights a broader issue of surveillance and privacy, noting that lawmakers have pressured privacy-focused apps to compromise their principles.

In summary, the author advocates for the use of GrapheneOS as a means of protecting personal privacy and control, regardless of its perception by law enforcement.

Summary of the Seven Sisters Eclipse

The Seven Sisters Eclipse happens when the moon, in its waning crescent phase, moves in front of the Pleiades star cluster, temporarily hiding the stars. This event has been occurring monthly since September 2023 and will continue until July 2029. The next significant eclipse will be on July 20, 2025, early in the morning, visible from much of the U.S. and Canada.

To see the eclipse, look towards the eastern horizon in a dark area away from city lights; no telescope is needed.

Summary: Resting Meat: A New Perspective

Traditionally, it's believed that resting meat helps keep it juicy. However, recent tests show that resting is more about controlling temperature rather than retaining juices.

1. Old Belief: Resting meat allows muscle fibers to relax and reabsorb juices pushed out during cooking, making it more flavorful.

2. New Findings: Research and experiments, including those by food scientists like Chris Young, suggest that the perceived juiciness is complex and not solely due to resting. The key factor is the internal temperature of the meat when sliced. When meat is rested, it can cool slightly, reducing vapor pressure and juice loss, but it doesn't necessarily retain more liquid.

3. Experiment Insights: A sensory test showed that tasters could barely distinguish between rested and unrested meat in terms of juiciness. This suggests that even if resting does affect moisture, the difference might not matter in practice.

4. Conclusion: It's beneficial to let meat rest, but the focus should be on reaching the desired internal temperature rather than a set resting time. This approach helps avoid overcooking and maintains the meat's crust.

Overall, the message is clear: resting meat should be viewed primarily as a method for temperature control.

The article discusses how smaller cities can improve their public transit systems by using tram-trains, which combine tram and train services. Many cities have railway lines that stop at the city center, requiring passengers to change to trams. Tram-trains allow for continuous travel through the city, increasing efficiency and reducing travel time.

Karlsruhe, Germany, pioneered the tram-train system, successfully integrating suburban railways with the tram network. This model has proven effective, with ridership increasing significantly after implementing tram-trains. However, tram-trains have limitations, such as lower speed and capacity compared to traditional trains.

Cities like Manchester and Melbourne have adopted different light rail models, including dedicated tram lines, to enhance service frequency. The article also highlights the potential for tram-trains in locations like Oxford, UK, and Charlotte, North Carolina, where existing rail infrastructure could be leveraged to create more connected transit systems.

Overall, tram-trains offer a cost-effective solution for improving transit in smaller cities, allowing better access to urban centers without the high expenses of building new metro systems.

A new feature in PostgreSQL, introduced in version 17, allows extensions and core components to manage dynamic shared memory easily through a registry. Initially, it only supported a function called GetNamedDSMSegment, but now two new functions—GetNamedDSA and GetNamedDSHash—make it simpler to allocate dynamic shared areas and hash tables.

To help users understand memory allocations, a new system view called pg_dsm_registry_allocations has been added. This view displays details about shared memory allocations, such as their names, types (segment, area, or hash), and sizes.

You can query this view with a simple SQL command to see the memory allocations for your extensions. Although these improvements were made after the PostgreSQL 18 feature freeze, they will be officially available in PostgreSQL 19, expected in Autumn 2026. If you need access to these features sooner, you can adapt the provided patches for your local builds.

The article discusses the concept of interactive programming in C, which allows developers to modify a program while it is running, particularly useful in game development. The author learned this technique from Casey Muratori's Handmade Hero project, where interactive programming was added to the game engine.

Key points include:

1. Shared Libraries: To enable interactive programming in C, the application is built as a shared library. This requires careful design to avoid global or static variables, as their state would be lost upon reloading the library.

2. Function Pointers: The use of function pointers in shared libraries must be managed carefully since the functions may disappear after a reload.

3. Example - Game of Life: The author created a simple Game of Life demo to illustrate interactive programming. Changes made to the game's source code can be instantly reflected in the running program without restarting it.

4. API Structure: The game’s API is structured to manage game state and function calls, consisting of functions for initialization, finalization, reloading, unloading, and stepping through game updates.

5. Library Loading: The wrapper program uses functions like dlopen() and dlsym() to load the shared library and access its API, checking the library's inode to ensure it has been updated before reloading.

6. Main Loop: The main program continuously calls the loading function and runs the game until it is told to stop.

The author expresses enthusiasm for using this technique to develop more complex games in C in the future.

The talk titled "Leprechauns, Root Causes, And Other Fairy Tales" discusses how complex systems fail and critiques the concept of root cause analysis. It begins with humorous stories about leprechauns and root causes to illustrate the absurdity of relying on simplistic explanations for complex issues.

Key points include:

1. Complex Systems: These systems, like banks or software, are inherently complex and prone to failures, regardless of how many root causes are addressed.

2. Constant Problems: Complex systems often operate in a "degraded mode," meaning they regularly experience minor issues, even if major incidents are infrequent.

3. Defenses Against Failure: Complex systems have numerous defenses that prevent small failures from escalating into major incidents. However, serious problems require multiple failures to align in a way that allows them to occur.

4. Misunderstanding Root Causes: The speaker argues that attributing incidents to a single root cause is misleading. Instead, accidents typically result from multiple contributing factors that must align to cause a failure.

5. Increased Complexity: Efforts to fix root causes often add new complexity to systems, potentially increasing risks instead of reducing them.

The speaker concludes by emphasizing that the idea of root causes is more of a myth than a helpful concept, comparing them to leprechauns—interesting but fictional. They suggest considering alternative models, like the Swiss cheese model of accident causation, for a more effective understanding of system failures.

Summary: The Cells That Breathe Two Ways

In Yellowstone National Park, researchers discovered a unique bacterium that can breathe both oxygen and sulfur simultaneously. This microbe challenges traditional beliefs about cellular respiration, as most organisms are either aerobic (using oxygen) or anaerobic (not using oxygen).

For billions of years, life on Earth thrived without oxygen, until cyanobacteria began producing it, leading to the Great Oxidation Event. Organisms had to adapt to this change, and understanding how they did so is still a mystery.

The bacterium, named Hydrogenobacter RSW1, was found in a hot spring and can utilize both aerobic and anaerobic respiration at the same time, indicating a hybrid metabolic process. This ability might help it survive in environments where oxygen levels fluctuate.

Researchers believe that such dual respiration could be more common than previously thought, and studying these microbes may provide insights into how early life adapted during the rise of oxygen on Earth.

The article "SETI at the Extremes" by Paul Gilster discusses the influence of science fiction on scientific research, particularly in the field of exoplanet studies. Many scientists have been inspired by sci-fi novels to explore unconventional ideas about life in extreme environments, even when we currently lack direct observational data on these worlds.

Gilster highlights notable examples, such as Hal Clement's "Mission of Gravity," which features a fictional planet called Mesklin and explores the interactions between humans and its alien inhabitants. This story is recognized for being one of the first to incorporate actual observational data about possible other solar systems, even though the data was later proven incorrect.

The article also mentions Robert Forward's "Dragon's Egg," which imagines life on a neutron star, suggesting that life could evolve in extreme conditions. Frank Drake, a pioneer of SETI (Search for Extraterrestrial Intelligence), proposed that life might exist in unusual environments, further fueling these ideas.

Gilster encourages researchers to think creatively about where life could exist, even in extreme and hostile environments, as new exoplanets are discovered. He references recent studies that explore the potential for life in high-energy settings, like neutron stars or black holes, and suggests that advanced civilizations might harness these extreme conditions for their development.

Overall, the article argues for an imaginative approach to astrobiology and SETI, inspired by science fiction, to broaden our understanding of potential life forms in the universe.

In Python 3.14, you can now connect a debugging session to a running Python process using the command python -m pdb -p pid. This post explains the improvements in Python that make this possible.

Python has always made it easy to create debugging tools because it handles exceptions and tracebacks simply. Tools like pdb come built-in and can be customized without needing deep knowledge of Python's internals. However, until now, using these tools often required modifying your code and restarting your program.

Python 3.14 introduces sys.remote_exec, which allows you to run a Python script in a running process without restarting it. You provide the process ID and the path to the script, and the script will execute when the process is ready, making debugging more straightforward.

For example, if you have a program that sums integers, you can inject a script to print the program's stack trace while it's running. The remote script executes in the context of the running program, allowing you to see its state without interrupting it.

This new feature lowers the barrier for creating debugging tools, making it easier for developers to write and use them. The post also mentions that while you can attach debuggers that suspend processes, using sys.remote_exec is safer as it doesn’t interrupt the running application.

In summary, Python 3.14's enhancements make debugging easier by allowing script injection into running processes, paving the way for better debugging tools.

A senior engineer recently moved to a small remote tech startup in Europe, seeking a visa and an exciting AI project, despite a pay cut from their previous US job. However, the project has been chaotic, with frequent changes in direction. The engineer was unexpectedly placed on a Performance Improvement Plan (PIP) by a new manager, who had not previously provided feedback. The reasons for the PIP seem subjective and linked to challenges arising from the fast-paced work environment. Additionally, the engineer has faced exclusion from important project discussions and received a contract amendment that would reduce their salary by nearly 20%. They believe their permanent Dutch contract offers strong protections and are documenting everything while pushing back through HR.

The engineer seeks advice on:

1. The true intention behind the PIP—whether it aims to genuinely improve performance or is a step towards termination.
2. Strategies for managing the emotional stress of working with a manager perceived as undermining them while maintaining professionalism.
3. Whether the company is trying to pressure them into resigning or accepting a low settlement offer.
4. Tips for staying strategic and composed despite feeling disrespected.

They appreciate any shared experiences or advice from the community.

The ScanRobot 2.0 is a new robot designed to help digitize rare books quickly and safely. Developed by researchers at the University of Tulsa's McFarlin Library, this machine can scan up to 2,500 books per hour, significantly faster than a human librarian, which could take days or weeks for a single book.

The robot works by using a camera that moves into the book's center and a vacuum system that gently pulls the pages aside for scanning. It then uses small bursts of air to turn the pages without damaging them. Although the robot operates autonomously, trained librarians must supervise it to ensure everything runs smoothly.

Currently, there are about 64,000 books at the library that can be scanned and made available online, with new public domain books added each year.

A new study reveals that diet, rather than lack of exercise, is the main cause of obesity. Researchers compared calorie burn in people from 34 countries with varying obesity rates and found that daily calorie expenditure is similar across different lifestyles. This challenges the common belief that being less active leads to weight gain.

The study involved over 4,200 adults and measured their energy use accurately. Findings showed that those in higher obesity rate countries burned only slightly fewer calories than those in lower obesity rate countries, indicating diet plays a crucial role in weight gain. Experts stress that the shift toward ultra-processed foods significantly contributes to rising obesity rates.

While exercise remains important for health, the focus should shift to improving diets to effectively address obesity.

Brandy Macaluso-Owens, a social worker in Port St. Lucie, Florida, received a surprising $174 bill after an outpatient appointment with a Cleveland Clinic doctor, highlighting a growing issue in the area. Since the Cleveland Clinic expanded to Florida, patients have been hit with unexpected "facility fees" during routine visits, which can add hundreds of dollars to their bills. These fees, traditionally charged for inpatient stays and emergency services, are now being applied to outpatient appointments, often without clear communication to patients.

The Cleveland Clinic defends these fees as necessary to maintain high-quality care and comply with safety standards, but many patients feel blindsided and struggle to afford the additional costs. With more than half of U.S. physicians now employed by hospitals, finding independent practices is becoming increasingly difficult for patients.

As healthcare costs rise and high-deductible insurance plans become common, many people are unable to manage these surprise bills. Efforts are underway at both state and federal levels to regulate or limit facility fees, with some states already implementing laws requiring better communication about these charges. However, the hospital industry argues that these fees are essential for funding necessary services.

Overall, dissatisfaction with facility fees is growing among patients, leading some to seek care from independent doctors to avoid additional costs.

The Linux kernel has recently seen some updates for the SPARC64 architecture, which has not had much activity for a long time. A developer named Thomas Weißschuh is working on updating SPARC64 to use a common library called vDSO, which helps share code across different CPU architectures. This change will reduce the amount of code needed for SPARC64 and make maintenance easier.

SPARC64 is the last architecture in the Linux kernel to adopt this vDSO library. However, since Oracle stopped developing SPARC CPUs eight years ago and SPARC systems are rare, it is uncertain how long support for SPARC64 will continue in the Linux kernel.

The article discusses a programming technique that utilizes uninitialized memory for efficient data management, particularly in representing sparse sets of integers. This method allows for fast operations while reducing the time needed for initialization.

Key points include:

1. Uninitialized Memory Usage: The trick involves leaving some array values uninitialized, which can improve performance for certain operations, turning linear time tasks into constant time.

2. Sparse Set Representation: The technique uses two arrays: a dense array that stores the actual elements and a sparse array that maps integers to their indices in the dense array. This allows for quick membership checks and efficient set operations.

3. Operations:

   • Adding an element and checking membership are both constant time operations.
   • Clearing the set can be done in constant time by simply resetting the count of elements.
   • Iterating through the elements is efficient as it visits them in the order they were added.

4. Comparison to Bit Vectors: While bit vectors offer quick membership checks and additions, their performance for clearing and iterating can be slower, especially when the set is sparsely populated.

5. Applications: This sparse set representation is particularly useful in scenarios like compiler design and graph algorithms, where frequent clearing of the set occurs.

Overall, the technique demonstrates a clever use of uninitialized memory to enhance performance while managing data structures effectively.
