Summary of the Expand and Contract Pattern for Database Changes

Introduction: Database schemas need to change over time as software evolves. It's crucial to transition these schemas safely without downtime, especially for live systems. The "expand and contract pattern" is a method that allows for gradual migration to new data structures while keeping the system operational.

What is the Expand and Contract Pattern? This pattern involves transitioning from an old data structure to a new one in a series of steps that don't disrupt service. It allows for easy rollbacks if any issues arise during the process.

Steps to Use the Expand and Contract Pattern:

1. Build and Deploy the New Schema: Create a new schema with minimal changes that runs parallel to the old one, without modifying existing columns directly.

2. Expand the Interface: Update client applications to write data to both the old and new structures while still reading from the old one.

3. Migrate Existing Data: Transfer data from the old structure to the new one, which may require data modifications to fit the new schema.

4. Test the New Interface: Validate that the new structure works correctly while the old one is still in use. This includes functional and performance testing.

5. Cut Reads Over to the New Interface: Shift client applications to read from the new schema while still writing to both structures.

6. Discontinue Writing to the Original Structure: Once confident in the new structure, stop writing to the old schema entirely.

7. Remove the Original Structure: After confirming that all clients use the new schema, delete the old data structure.

Example Application: The guide includes an example involving a table for playground equipment. The original structure was updated by creating a new table for playground data, ensuring both tables were maintained during the transition. Data was migrated carefully, and the system was validated before finally removing the old structure.

Conclusion: The expand and contract pattern is an effective way to manage database schema changes without downtime. By following systematic steps, developers can minimize disruptions and maintain service for clients.

The author shares their experience creating a complex 3D-printed art piece called "Marble Fountain" after starting at Formlabs in September 2023. They enjoy procedural generation and wanted to design an intricate structure that would take advantage of advanced 3D printing technology.

The project began with a simple system that randomly placed points and created paths for marbles to travel. The author faced challenges in optimizing the track design to ensure marbles could move smoothly without losing speed or getting stuck. They developed algorithms to maintain the path's shape and ensure safe turns.

Support structures for the design were easier to create and required aesthetic adjustments rather than structural fixes. The author noted that while their models take 5-20 minutes to export, they could optimize them further with different tools.

Looking back, the author invested a lot of time in this hobby project, which began in February 2024 and culminated in a gallery showing. They experienced burnout due to the intense final preparations but were able to get the system running reliably, despite minor issues. The author expresses gratitude to a friend for support throughout the project's development. They also plan to improve the project in the future and have shared their work on GitHub.

Quad9, a non-profit DNS resolver, is facing serious challenges due to legal battles over blocking pirate sites, which it describes as an "existential threat" to its service. Unlike large companies like Google and Cloudflare that can manage the legal costs, Quad9 lacks the financial resources to fight these battles effectively.

In May 2024, a French court ordered major tech companies to block access to several pirate streaming sites, and this has led to more rightsholders targeting smaller DNS providers such as Quad9. The organization argues that copyright holders are unfairly shifting the burden of enforcing piracy laws onto neutral internet providers instead of targeting the infringers directly.

This situation could threaten the infrastructure of the internet, as smaller providers may not survive the legal pressures. Quad9 raises critical questions about the accountability of technical infrastructure, the reach of national laws on global networks, and the implications for privacy and internet accessibility. They warn that if only a few corporations can comply with these legal demands, it could lead to a less open and more centralized internet.

GOG's Preservation Program aims to keep classic games playable on modern systems, but it faces unexpected challenges. Launched last November, the program intends to maintain and update hundreds of games, even if GOG loses the rights to sell them. However, many older games have quickly become unplayable again due to technical issues, such as compatibility with modern controllers and screen resolutions.

GOG had hoped to preserve 500 games by the end of 2025 but is now aiming for 300 to 350 due to the complexity of the task. Issues like outdated digital rights management (DRM) and difficulties in contacting original game rights holders complicate the process. In some cases, GOG even hired private detectives to find elusive owners of game rights. Despite these hurdles, GOG is committed to preserving gaming history, especially as many publishers abandon their games shortly after release.

The text is asking someone about their current projects and if they have any new ideas they are considering.

Most store-bought clothing comes in fixed sizes and styles, making it hard to adapt to changes in body shape or fashion trends. While alterations can help, they often involve sewing and can't be reversed. To address this, we suggest a modular design for clothing that allows for easy resizing, restyling, and reuse. Our approach includes a set of modules and connectors that serve as the foundation for these garments, a method to break down garments into these modules, and a digital tool for designing and simulating modular clothing. User feedback indicates that this modular design can create a variety of garments and allows users to easily change sizes and styles while reusing the same components.

The text discusses a method for estimating probabilities of sets of binary variables using different statistical approaches. Here are the key points simplified:

1. Problem Overview: The focus is on estimating the probabilities of subsets of a set (X) of binary variables based on given information about those subsets.

2. Information Updates: Each piece of information updates the probability of a subset based on logical conditions. For instance, a condition may specify that at least one pair of members in a subset has different values.

3. Dempster-Shafer Theory: This theory provides a way to assign probabilities directly to subsets of events. It allows for overlapping sets and uses mass assignments that must sum to 1. Key concepts include:

   • Belief (bel): Measures the support for a subset.
   • Plausibility (pl): Measures the extent to which a subset could be true.

4. Combining Information: Dempster’s rule is used to combine multiple sources of information, maintaining a balance and addressing conflicts.

5. Practical Example: The author demonstrates the theory using GNU SETL, a programming language suited for set operations. They calculate belief and plausibility for specific queries based on initial information updates.

6. Results: The example yields belief and plausibility values for three queries, demonstrating the effectiveness of the Dempster-Shafer approach.

7. Frequentist Approach: As a contrast, a Frequentist method is briefly mentioned. It involves adjusting probabilities based on new information but is less elegant and can be computationally intensive.

In summary, the text explores using Dempster-Shafer theory to estimate probabilities of subsets of binary variables, providing a structured method to combine overlapping information effectively.

This article discusses the issue of "BGP zombies," which are routes that get stuck in the Internet's routing system, causing disruptions in traffic. BGP (Border Gateway Protocol) is crucial for directing Internet traffic, but sometimes routes don't get updated properly due to software bugs or delays in processing withdrawals. This can lead to inefficient routing and traffic loops.

Key Points:

1. BGP Zombies: These are routes that should no longer exist but linger due to various issues, causing network problems and inefficient traffic routing.

2. Path Hunting: This is the process where routers search for the best route after a specific prefix (a more detailed route) is withdrawn. If some routers are slower to update, they may continue to try routing through a now-nonexistent route, leading to potential zombies.

3. On-Demand Announcements: The use of "on-demand" BGP announcements, where routes are only announced when needed, can increase the chances of BGP zombies forming.

4. Zombie Lifespan: While BGP zombies typically do not last long in major networks, they can still cause significant issues, with some cases lasting over 10 minutes.

5. Mitigation Strategies: Cloudflare is exploring ways to minimize the impact of BGP zombies, such as improving internal traffic forwarding and encouraging better routing practices among customers.

6. Future Developments: Ongoing efforts are being made to measure and address BGP zombie issues, including implementing new standards to help routers detect problems faster.

The text discusses the complexities of decompiling Java class files, particularly focusing on handling exceptions in the Java Virtual Machine (JVM). Here are the key points:

1. JVM Basics: The JVM uses a stack-based architecture, where most operations manipulate the stack. Control flow, like loops and conditionals, is straightforward, but exceptional control flow (like try…catch blocks) is more complicated.

2. Exception Handling: In Java, exceptions are managed through an exception table that maps regions of code to their respective exception handlers. This allows a single try block to manage various types of exceptions that may arise.

3. Nesting and Overlapping: Exception tables can have entries that overlap, and the structure of these entries can be complex, making it challenging for decompilers to accurately interpret them. Real-world Java class files can exhibit unexpected structures not easily handled by simplistic models.

4. Finally Blocks: The behavior of finally blocks, which must always execute, adds further complications. The Java compiler (javac) duplicates the code in the finally block for each possible exit point from the try block to ensure it runs regardless of whether an exception occurred.

5. Potential Errors: Both false positives (catching exceptions that shouldn't be caught) and false negatives (missing exceptions that should be caught) can occur due to the unpredictable nature of exceptions in the JVM.

6. Type Checking: The JVM has two type checkers: one that verifies types using a pre-defined table (StackMapTable) and another that infers types at runtime. This can affect exception handling, particularly in older class files.

7. Decompilation Challenges: Decompiling Java bytecode involves interpreting complex exception handling structures, ensuring that exit points are correctly managed, and maintaining the integrity of type checking. The author shares that their approach to dealing with these issues is not perfect but aims to simplify the process.

Overall, the text illustrates the intricacies of decompiling Java class files, especially regarding exception handling and the challenges that arise from the JVM's design.

Summary of the History of Time Machine

Before Mac OS X, Apple did not have a reliable backup tool, and users typically relied on third-party options like Dantz Development's Retrospect. In 2004, Apple introduced a backup app with its cloud service .Mac, but it wasn’t until 2007 that Time Machine was launched with Mac OS X 10.5 Leopard. This was a significant advancement, as it allowed users to back up their files easily.

Time Machine works by backing up only the files that have changed since the last backup, using a system called hard links and features from the HFS+ file system. This made each backup appear complete while only copying new or altered files, which saved space and time.

Over the years, Time Machine has evolved significantly. It introduced features like Mobile Time Machine for laptops, incorporated snapshots with the introduction of APFS in High Sierra, and improved its backup efficiency by using synthetic snapshots in later versions. However, there have been challenges, such as the difficulty in transferring backups from APFS.

Overall, Time Machine has transformed how Mac users handle backups, making it easier and more efficient to protect their data.

This monograph explains the key principles behind diffusion models, which are used to transform noise into data. It starts by outlining a forward process that turns data into noise and how this connects to a simple prior through various stages. The main aim is to learn a reverse process that can convert noise back to data while also recovering the intermediate stages.

The text presents three main perspectives on diffusion modeling:

1. Variational View: This approach, inspired by variational autoencoders, focuses on gradually removing noise.
2. Score-Based View: This view learns how to adjust samples toward areas of higher likelihood in the data distribution.
3. Flow-Based View: This perspective treats the process as following a smooth path from noise to data, guided by a learned velocity field.

All these views rely on a time-dependent velocity field that helps move from noise to data. The process of generating data involves solving a differential equation along a continuous path.

Additionally, the monograph discusses methods for generating data in a controlled manner, efficient ways to solve numerical problems, and models that learn direct mappings between different times. It aims to provide a clear and mathematically sound understanding of diffusion models for readers familiar with basic deep learning concepts.

Researchers at Intermountain Health have found that personalizing vitamin D3 doses for heart attack survivors can reduce their risk of having another heart attack by 50%. This approach involves closely monitoring blood levels and adjusting dosages to maintain optimal vitamin D levels. Traditional studies did not track blood levels, which may have missed this important connection.

The study, presented at the American Heart Association's Scientific Sessions, involved 630 patients who had experienced a heart attack. Those receiving targeted vitamin D treatment had their blood levels monitored and adjusted to reach a goal of over 40 nanograms per milliliter. More than half of these patients needed higher doses than usual.

While the overall risk of major cardiac events was similar in both groups, the targeted treatment significantly decreased the likelihood of a second heart attack. The researchers aim to conduct larger trials to further explore the benefits of managing vitamin D levels for heart health.

On November 3, 2025, developer Maciej Mensfeld detailed a perplexing memory bug in Ruby that led to a common error: "undefined method 'default' for an instance of String." This issue was linked to a specific version of the FFI (Foreign Function Interface) library. The bug occurred when Ruby's garbage collector (GC) mistakenly freed an internal Hash, allowing a String to be allocated in its memory space. This resulted in unexpected behavior because the C code still referenced the old memory address, now holding a String instead of a Hash.

The investigation revealed that the problem was exacerbated by using musl libc on Alpine Linux, which is often problematic with precompiled gems. Initially, the developer suspected alignment issues but found that the memory layout was correct. The breakthrough came when it was discovered that FFI's C extension was missing write barriers—key mechanisms that inform the GC about object references. Without these barriers, the GC could free objects that were still in use, leading to the catastrophic memory bug.

The fix was implemented in FFI version 1.17.0, which included proper write barriers to ensure that the GC does not free necessary objects. Developers using versions prior to 1.17.0 are urged to upgrade to prevent this rare but serious bug from occurring in production environments. The author emphasized the importance of understanding how Ruby manages memory and the implications of GC behavior in C extensions.

The text discusses a proposal about handling contributions generated by language models (LLMs) in the open-source project "runc" under the Open Containers organization. Here are the key points:

1. Increase in LLM-generated Contributions: There has been a rise in pull requests and bug reports that appear to be generated by LLMs.

2. Proposed Policy: The author suggests creating a policy to decide what LLM-generated content should be accepted. They personally believe that no LLM-generated submissions should be accepted.

3. Issues Considered Spam: The author argues that LLM-generated issues should be closed as spam, as the descriptions often contain irrelevant or incorrect information.

4. Code Submissions: For LLM-generated code, the author believes that contributors should be able to explain their code in their own words, indicating they understand it.

5. Legal Concerns: The author mentions that LLM-generated code may not meet legal requirements, making it a reason to reject such submissions.

6. Reference to Other Projects: The author notes that another project, Incus, has already banned LLM usage in their contribution guidelines.

In summary, the discussion revolves around setting clear guidelines for managing contributions from LLMs to maintain quality and legal compliance in the runc project.

The European Parliament is considering new rules to prevent pollution from tiny plastic pellets, known as nurdles. These pellets, which are small and lightweight, can easily spill during transport and are difficult to clean up once they enter the environment. In 2019, between 52,140 and 184,290 tonnes of these pellets were released in the EU, equivalent to thousands of truckloads.

When nurdles spill, they can harm marine life and disrupt local economies, particularly fishing and tourism. Past incidents, like a major spill in Sri Lanka, have shown how widespread and damaging these pollutants can be. The proposed regulations would require companies to implement better safety measures during the handling and transport of nurdles.

Current practices often lead to spills not just during transport but throughout the entire supply chain. The plastic industry is under pressure to address these issues, as many stakeholders are aware of the environmental impact of plastic pollution. The situation highlights the ongoing challenges of managing plastic waste and the need for global cooperation in reducing plastic production and pollution.

A person frustrated with pigeons pooping on their balcony decided to create a high-tech solution: a Wi-Fi-enabled water gun that can be controlled online. They explored many common methods to deter pigeons but found them ineffective, including plastic decoys, sounds, and even getting a cat. They settled on a robotic water gun that detects pigeons using a webcam and a Python script.

Here's how it works:

1. Water Gun Setup: They bought a cheap electric water gun and modified it for internet control using a small Wi-Fi board called Wemos D1 Mini.
2. Camera Use: An old iPhone was repurposed as a camera to monitor the balcony, streaming live video.
3. Software: A Python script analyzes the camera feed to detect movement. If it sees a pigeon, it triggers the water gun to spray.
4. Networking: A small program was created to allow the water gun to communicate with the user's laptop over different networks.

After setting it up, the user initially saw no pigeons for six days, but eventually, the birds returned. They plan to keep experimenting with the system. The project highlights the creative use of technology to solve everyday problems in a humane way.

Summary of the CHIP8 Project

Overview: The project aimed to implement CHIP8, a simple Instruction Set Architecture (ISA) using VHDL, along with an emulator, assembler, and a game. The focus was on learning and understanding computer systems rather than creating a production-ready product.

Key Components of CHIP8:

• Registers: 16 general-purpose 8-bit registers, a 16-bit address register (I), a program counter (PC), a stack pointer, and timers for sound and delay.
• Display: A 64x32 pixel monochrome display that uses XOR for rendering graphics and detecting collisions.
• Input: A 16-key keypad for user interaction.
• Opcode: 35 different operations (opcodes) to control the emulator.

Implementation Details:

1. Emulator:

   • The emulator was built in C, focusing on detailed opcode implementation without using abstraction layers.
   • Each opcode is fetched and executed in a straightforward manner using conditional statements.

2. Assembler:

   • Developed using C++ to allow for a more functional programming approach.
   • The assembler translates source code into binary opcodes, utilizing a tokenization process to recognize labels, operators, and values.

3. Game Development:

   • A Flappy Bird clone was created as an application of the implementation, showcasing the emulator's capabilities.
   • The game includes sprite definitions, variables, and control flow for game mechanics.

4. Hardware Implementation:

   • Designed for an Altera FPGA board, featuring a clock divider for timing.
   • Uses a finite state machine to manage instruction execution and RAM/VRAM communication.

Challenges and Considerations:

• The implementation is not perfect; it lacks unit tests and has some inefficiencies.
• The drawing of sprites is done in a straightforward manner, but future improvements could integrate it better with the VGA generator.

On November 9, 2025, OpenAI released a new model called GPT-5-Codex-Mini, a smaller and cheaper version of GPT-5-Codex. It's currently accessible only through the Codex CLI tool and a VS Code extension, with broader API access expected soon.

A developer decided to reverse engineer the Codex CLI tool to prompt the new model directly. The Codex CLI is an open-source project written in Rust, and the developer created their own version to add a new command called "codex prompt" to send prompts directly to the OpenAI API.

They faced several challenges, such as the model's tendency to refer to local files and tools instead of simply responding to prompts. Ultimately, they modified the command to prevent it from accessing tools and ensured it could display results correctly. The developer also added a debug option to track the API requests and responses.

After the final adjustments, they successfully generated SVG images of a pelican riding a bicycle using both the GPT-5 and GPT-5-Codex-Mini models, though the output from GPT-5-Codex-Mini was less satisfactory. The developer shared their code for others to review.

Summary of Google Summer of Code 2025 Report on Sandboxing for NetBSD

The report, written by Vasyl Lanko for Google Summer of Code 2025, discusses efforts to introduce sandboxing in NetBSD, which currently lacks effective sandboxing techniques. The existing method, chroot, is limited and does not provide isolation for networking or inter-process communication.

Project Goals:

• Implement a sandboxing mechanism similar to Linux namespaces, which isolate system components for applications.
• Utilize NetBSD's compat_linux feature to run Linux binaries and support namespace functionality.

Key Focus Areas:

1. UTS Namespace: This allows applications to have their own hostname while the system retains its original hostname. It involves creating copies of hostname data and managing it through credential references.
2. MNT Namespace: This isolates file system mounts, allowing users to manage their own mounts without affecting the overall system. Implementation is more complex than the UTS namespace and requires understanding both Linux and NetBSD systems.

Implementation Steps:

• Use the kauth subsystem for managing credentials and namespaces.
• Modify kernel code to access namespace-specific information instead of global system data.

Current Status:

• Code is available on GitHub, with UTS namespace implemented and work ongoing for the MNT namespace.
• Future work includes exploring additional namespace types and enhancing management functionalities.

Challenges Encountered:

• Differences in system call behaviors between Linux and NetBSD led to unexpected complexities.
• A significant amount of research was needed to understand the different virtual file system (VFS) concepts.

Conclusion: The project aims to enhance NetBSD by directly implementing Linux-like namespaces, improving sandboxing capabilities. The experience gained has built confidence for future contributions to open-source projects. Special thanks were given to mentors and the NetBSD community for their support throughout the project.

Vyacheslav Penchukov, known as "Tank," is a former cyber-crime kingpin currently imprisoned in Colorado. He led several notorious hacking gangs, including Jabber Zeus, which stole millions from victims worldwide, including small businesses and charities. Penchukov spent nearly a decade on the FBI's Most Wanted list before his arrest in Switzerland in 2022.

In an exclusive interview, he discussed the inner workings of cyber-gangs, his rise in the cyber-crime world, and the evolution of hacking techniques from bank theft to ransomware attacks targeting major corporations and hospitals. Despite his criminal actions affecting thousands, Penchukov shows little remorse for his victims, claiming only that he regrets trusting fellow criminals too much.

During his early cyber-crime days in Ukraine, he earned significant money, leading a lavish lifestyle. However, after Russia's invasion of Crimea disrupted his legitimate business, he returned to cyber-crime for quick profits. He became involved in ransomware, which he described as more challenging but highly lucrative. His gang's attacks have led to severe consequences for institutions like the University of Vermont Medical Center.

Penchukov's story highlights the harsh realities of cyber-crime, the mindset of hackers, and the impacts on innocent victims. While he hopes to be released early from his nine-year sentence, he acknowledges the constant paranoia and betrayal that characterize the cyber-crime world.

The author, a recent computer science graduate, reflects on their struggle to find a job despite following all the traditional pathways to career success, such as obtaining good grades, completing internships, and gaining relevant experience. They describe the current job market as "broken," particularly for new graduates, with terms like "white collar recession" and "graduate jobpocalypse" becoming commonplace.

While official unemployment rates may appear low, the reality is that there are many graduates competing for fewer entry-level positions. Automation and outsourcing are leading to job losses in fields that once seemed secure, including computer science. The author notes that companies are increasingly prioritizing efficiency and automation over hiring new graduates, often replacing entry-level roles with AI tools or more experienced workers.

The job market is shifting towards roles that require unique skills, as many traditional jobs can now be automated or performed by cheaper labor in other countries. This creates a challenge for new graduates, who find their skills and experiences may not be enough to compete against automated systems and a global workforce.

The author emphasizes the need for individuals to carve out unique niches ("out of distribution humans") in the workforce, as many traditional roles are being eroded. They express concern that society has not yet fully grasped the implications of this shift, as many political and economic systems still prioritize job creation as a central goal, despite the reality of increasing automation.

Overall, the author highlights the growing challenges for recent graduates in a rapidly evolving job market, where traditional pathways to employment are becoming less viable.

Summary of Daemon Example in C

This post explains how to create daemons in C, with a focus on the "double fork" method for daemon creation.

Key Points:

1. What are Daemons?

   • Daemons are background processes that run without a controlling terminal, often used for services like web servers and email servers. They typically log output to files instead of the console.

2. Creating Daemons:

   • There are multiple ways to create daemons:
     • Using fork() programmatically.
     • Utilizing systemd services.
     • Using the daemon function from the glibc library (not recommended for proper daemon behavior).

3. Double Fork Method:

   • The double fork technique involves:
     1. Forking the process to run in the background.
     2. Calling setsid() to create a new session and detach from the terminal.
     3. Forking again to ensure the daemon cannot acquire a controlling terminal.
   • This method helps prevent issues like zombie processes and ensures the daemon is orphaned and managed by the init process.

4. Example Code:

   • The example includes C code that demonstrates how to implement the double fork method, manage file descriptors, and redirect standard input/output to /dev/null.

5. Running the Daemon:

   • To run the daemon, you compile the code and execute it. The process will run silently in the background.

6. Analyzing the Daemon:

   • You can use commands like ps to check the daemon's process ID and confirm that it has no controlling terminal.

7. Known Issues:

   • There are some compatibility issues when running the daemon on macOS, as it does not log to the expected files.

8. Further Development:

   • Future enhancements could include adding signal handlers for better process management and implementing logging mechanisms.

This guide serves as a foundation for understanding and creating daemons in a Unix environment using C.

Summary of Project Zero Update - November 3, 2025

Title: Defeating KASLR by Doing Nothing at All

Seth Jenkins from Google's Project Zero discusses a security issue related to the Linux kernel's Address Space Layout Randomization (KASLR) on Pixel devices. His research uncovered that the kernel's linear mapping—a part of the kernel's memory that directly represents physical memory—is not randomized on Pixel devices. This lack of randomization allows attackers to predict memory addresses, making it easier to exploit the system.

Key Points:

• Linear Mapping: This area in the kernel allows for direct access to physical memory addresses. On Pixel devices, it has a static base address, which simplifies address calculations for attackers.
• Kernel Decompression: On Pixel phones, the kernel is often decompressed to the same physical address at every boot, unlike some other devices which use random physical addresses.
• Exploitation Potential: The predictable memory layout enables attackers to place malicious data at known kernel addresses, which can be used for exploitation, even if KASLR is enabled.
• Impact on Security: Although KASLR still helps mitigate remote attacks, the lack of randomization in the kernel's linear mapping makes it less effective against local attackers.
• Future Recommendations: To improve security, it is suggested that the Linux kernel should implement randomization for the linear mapping and physical memory allocation.

In conclusion, while KASLR provides some defense, its reliability is diminished on Pixel devices due to these issues. Improvements are needed to enhance the overall security of the Linux kernel and Android systems.

The author, a tech-savvy parent, shares their experience of helping their children build their own Linux computers. Initially, they used Ubuntu, but the kids have since transitioned to Arch Linux. They bought a second-hand desktop and assembled it together, which was an exciting learning experience.

The author contrasts the challenges of finding software on Windows, which often leads to expensive or unreliable options, with the ease of finding free and useful software on Linux. Their children appreciated the freedom and community that came with using Linux.

Now, a friend wants to provide the same experience for their 8-year-old daughter. The author plans to help them buy a second-hand desktop and install Linux. They are seeking suggestions for software to install and any educational ideas or mini-curriculums that could enhance the learning experience with Linux and open-source software.

Iran, particularly its capital Tehran, is experiencing a severe drought this autumn, with record-low rainfall and nearly empty reservoirs. Officials are urging residents to conserve water, and President Masoud Pezeshkian warned that if conditions do not improve, water rationing may be necessary, potentially leading to the evacuation of Tehran—a suggestion that has drawn criticism.

Currently, key reservoirs like the Latian and Karaj Dams are critically low, with the Karaj Dam holding only 8% of its capacity. The situation is affecting daily life; residents are resorting to buying water for basic needs.

The government is hoping for late autumn rain, but forecasts are uncertain. In addition to the drought, problems like water leakage from old infrastructure and impacts from a recent conflict with Israel have worsened the crisis. Other cities like Mashhad are also struggling, with water reserves dropping to alarmingly low levels.

This water crisis has been developing for decades, with warnings from leaders, including Iran's Supreme Leader, going unaddressed. Today, over 16 million people in Tehran, Karaj, and Mashhad face the threat of water shortages.

A new programming language called Tabloid has emerged, designed to mimic clickbait news headlines. Here are the key features:

1. Function Declaration: Functions are declared using "DISCOVER HOW TO ... WITH".
2. Variable Assignment: Use "EXPERTS CLAIM ... TO BE" for assigning values.
3. Output: All printed output starts with "YOU WON'T WANT TO MISS" and is in uppercase with an exclamation point.
4. No Loops: Instead of traditional loops, Tabloid uses recursion due to the fast-paced nature of news.
5. Ending Programs: All programs must finish with "PLEASE LIKE AND SUBSCRIBE".

Tabloid is fully functional and Turing complete, supporting numbers, strings, and booleans. It has an interpreter in JavaScript and a compatible version in Racket. The creator also made a more conventional language called Ink. Overall, Tabloid combines programming with the sensational style of tabloid headlines.

The text discusses the redundancy and inefficiencies in the development of desktop environments for Linux, highlighting that most of them are based on the Windows design from Windows 95. Despite the vast number of different Linux desktops (over 20), they often share similar layouts and functionalities, leading to unnecessary reinvention of the wheel.

Key points include:

• Most Linux desktop environments mimic the Windows 95 design, which has not changed significantly over the years.
• The original Windows Explorer introduced a unique combination of features that many Linux desktops try to replicate but often fail to achieve the same elegance.
• Various Linux desktops (like Xfce, MATE, Cinnamon, and GNOME) are built using different programming languages and toolkits, making integration difficult.
• The author argues that this fragmentation leads to wasted resources, as many developers work on similar projects without collaboration.
• There is a call for the FOSS community to work together more effectively, sharing components and standards to create a more unified and functional user experience.

In summary, the article critiques the lack of innovation and collaboration in the Linux desktop environment space, suggesting that the community could achieve greater functionality and efficiency by cooperating and consolidating efforts.

Hephaestus: A Self-Adapting AI Workflow Framework

Hephaestus is a new AI framework that allows AI agents to create their own instructions while working on complex software projects. Instead of following a strict, predefined plan, agents can dynamically generate tasks based on real-time discoveries.

Key Features:

1. Dynamic Workflows: Agents can initiate tasks in any phase—Planning, Implementation, or Validation—based on what they find during their work.

2. Self-Branching: For example, if a testing agent discovers an optimization opportunity, it can create a new investigation task without needing predefined instructions.

3. Parallel Processing: Agents work simultaneously on different components of a project, increasing efficiency.

4. Real-Time Adaptation: The workflow evolves based on actual discoveries rather than anticipated scenarios, making it more flexible and responsive.

5. Semi-Structured Approach: Hephaestus combines the benefits of structured workflows (like defined phases) with the flexibility of unstructured systems (allowing agents to create detailed tasks on the fly).

Workflow Example:

• Start with a product requirements document (PRD).
• An agent analyzes the PRD and creates tasks for each component.
• As agents complete tasks, they can discover new opportunities or issues, which leads them to spawn new tasks automatically.

Benefits:

• Increased Efficiency: The system adapts in real-time, allowing for faster problem-solving and innovation.
• Reduced Rigidness: Unlike traditional frameworks that require exhaustive upfront planning, Hephaestus allows for unexpected discoveries to shape the workflow.

Getting Started:

Hephaestus requires certain tools and configurations but promises a quick setup guide to help you build your first self-adapting workflow in just 10 minutes.

For more details, check out the full documentation or join the community for support and discussions.

In early November 2025, domains linked to the Aisuru botnet dominated Cloudflare's list of the most requested websites, even surpassing major companies like Amazon, Apple, Google, and Microsoft. Cloudflare's CEO stated that the botnet is manipulating the rankings to boost its malicious domains while also attacking Cloudflare's DNS service.

Aisuru is a growing botnet made up of hacked Internet of Things (IoT) devices, capable of launching massive attacks. Recently, it switched its DNS requests to Cloudflare's server, which led to its domains appearing in the rankings. Cloudflare began redacting these domains from its list to address concerns about security and brand confusion.

Experts criticized Cloudflare for allowing these malicious domains to appear in their rankings, arguing that the rankings should reflect real human usage, not just DNS query volume. Cloudflare is working to improve the accuracy of its ranking system.

Most Aisuru-related DNS queries originate from the U.S., with many domains registered under the .su top-level domain, which is often associated with cybercrime. Monitoring attempts to access .su domains could help identify Aisuru bot activity on networks.

Trilogy is an experimental SQL-first analytic IDE, similar to tools like Redash and Metabase. It introduces a modified syntax called Trilogy, which includes a semantic layer to improve code reuse and composability in SQL.

The tool aims to address three main issues with SQL:

1. Boilerplate Code: Adjusting queries can be tedious. Trilogy allows queries to operate on the semantic layer instead of raw tables, reducing boilerplate.
2. Changing Data Sources: Updating reports when data sources change is cumbersome. The semantic layer lets users update data bindings without altering dashboards or queries.
3. Visualizing Data: The process of turning SQL queries into visualizations is often complicated. Trilogy simplifies this by using the semantic layer to enhance typing, provide better defaults, and enable automatic drilldowns and cross-filtering.

Trilogy currently supports bigquery, duckdb, and snowflake. Feedback and contributions are encouraged. For more information, you can visit their website and check their GitHub repositories for the frontend and language components.

The paper discusses challenges in measuring the performance of AI models. It highlights that existing methods may not effectively capture the true capabilities of these models. The authors suggest improvements to better evaluate AI performance, making it easier for researchers and developers to understand how well their models work.

The text discusses the impact of large language models (LLMs) on the development of programming languages, suggesting that LLMs may actually make it easier to create new programming languages. Several experts believe this is an opportune time to develop new languages, and LLMs can assist in this process by lowering the costs associated with language development.

It introduces the concept of Domain-Specific Languages (DSLs), which are small languages tailored for specific tasks within software systems. DSLs enhance communication between developers and domain experts, and LLMs could help generate code and documentation for these languages.

The text also touches on the differences in how programming languages and LLMs tokenize code, which affects the efficiency of code generation. It compares the token efficiency of different programming languages like JavaScript, Python, and APL, showing that some languages can be more concise and readable, which is beneficial for LLMs.

The author proposes that instead of creating general-purpose languages for LLMs, developers should focus on small, task-specific DSLs. These DSLs can be more easily designed and maintained, especially with LLMs automating parts of the development process.

In conclusion, the rise of LLMs could revitalize interest in language design, making it easier to create efficient and effective programming tools.

This article discusses the challenges of getting the old OMAP3530 BeagleBoard to boot from USB on modern PCs. The author, Doug Brown, encountered issues while experimenting with USB booting and debugging a UART driver bug.

Key Points:

1. Background: The OMAP3530 BeagleBoard, from 2008, supports USB booting, but finding relevant information is tough due to its age. The author used a utility called omap_loader to help with the process.

2. Initial Issues: When attempting to upload boot files via USB, errors occurred on newer computers, particularly those with USB 3.0 ports. Older computers worked well, indicating a problem related to how modern USB controllers handle data transfer.

3. USB Transfer Problems: The newer machines sent data too quickly, causing the OMAP’s bootloader to fail to respond correctly. The author discovered that adding a 1 ms delay between data transfers resolved this issue.

4. Reading from X-Loader: Issues also arose when trying to read data from X-Loader before it was fully initialized. A 20 ms delay was needed to allow X-Loader sufficient time to start up before attempting to read from it.

5. Troubleshooting: The author used a USB sniffer to analyze the data transfer process and identified several timing issues with modern USB host controllers that caused communication failures.

6. Final Success: After implementing these delays, the USB boot process worked successfully on all tested computers. The improvements have broader implications, helping with projects involving older devices like Nest thermostats that also use OMAP processors.

7. Conclusion: The author plans to submit the fixes to the omap_loader project, highlighting how a side project can lead to useful developments in other areas.

This text discusses how Cloudflare developed WARP, a security and performance app, by essentially creating a high-performance VPN using Linux's networking capabilities. Here are the key points:

1. Purpose of WARP: WARP was designed to securely and efficiently manage internet traffic for millions of mobile clients.

2. Understanding IP Packets: Data sent over the Internet is broken into smaller packets, each with a source and destination address. Local networks use routers to convert private IP addresses into public ones through a process called Network Address Translation (NAT).

3. VPN Functionality: WARP operates like a VPN, encapsulating private network packets within public ones so users can access the Internet securely.

4. Linux Networking: The Linux operating system is used to manage NAT and routing. It can rewrite the source IP of outgoing packets to ensure they reach their destination correctly.

5. Conntrack Module: This module helps manage connections and ensures that packets are routed correctly. It tracks active connections and allows for effective NAT and firewall management.

6. Packet Marking: Packet marking can be used to apply specific firewall rules and routing decisions, making it easier to manage network traffic.

7. Challenges of IPv4: Due to the limited number of available IPv4 addresses, Cloudflare faced challenges in scaling WARP. Each server would require a unique IP address, leading to high costs.

8. Future Considerations: To address these challenges, Cloudflare is exploring solutions like IP sharing and is planning to share more in a future post.

In summary, the text outlines the technical journey of developing WARP, focusing on how Cloudflare utilized Linux's networking features to create a scalable and secure VPN solution while navigating the limitations of IPv4 addresses.

The text discusses two contrasting ideas about the internet: the "dead internet theory" and the "alive internet theory."

• Dead Internet Theory: This suggests that bots will eventually outnumber real people online.
• Alive Internet Theory: This counters that belief by emphasizing that the internet will always be filled with real people who connect, help each other, and share experiences.

The "alive internet theory" is presented as an interactive experience where users explore digital artifacts from the Internet Archive, showcasing genuine human creations like images, videos, and songs. It highlights the difference between humans and machines and raises questions about what it means to be human in the modern web. The experience is designed to be engaging on both desktop and mobile devices, with new content each time it's accessed, but it may include adult materials.

He believes in creating characters and stories that lead to affirmations of good values. Gass, on the other hand, focuses on the beauty and complexity of language, suggesting that the aim of his writing is to create objects of beauty rather than to convey specific moral messages.

2. Communication in Fiction: Gardner emphasizes the importance of communication in writing, constantly revising his work to clarify meaning. Gass expresses skepticism about the ability of fiction to clearly communicate complex ideas, preferring instead to explore language's transformative qualities.

3. Character Development: Gass defines a character as a linguistic element that shapes the text, while Gardner sees characters as vivid creations drawn from real-life experiences. Gardner believes that characters should evoke emotional responses from readers.

4. Reader Engagement: The two differ in how they view reader engagement. Gardner believes in creating a continuous, immersive experience for readers, while Gass argues that modern readers often interact with texts in a more fragmented way.

5. Artistic Intent: Gass feels that writers should focus on creating beautiful works, independent of moral implications, while Gardner believes writing should aim for clarity and moral affirmation.

6. Differences in Writing Motives: Gass sees writing as a means of controlling language and expressing his inner thoughts, while Gardner views writing as a way to understand and improve oneself and the world.

In summary, Gass and Gardner debate the roles of morality and beauty in fiction, with Gass favoring a focus on aesthetic expression and Gardner advocating for a moral purpose in storytelling. Their differing philosophies highlight the complexities of literary creation and the varied motivations behind writing.
