Summary: Using AI Generated Code Will Make You a Bad Programmer

The article argues that relying on AI-generated code can hinder your growth as a programmer. Here are the key points:

1. Learning Opportunities Lost: Using AI to write code means missing out on essential learning experiences. Just as you can't improve at a sport without practice, you can't grow as a programmer without writing code.

2. Skill Atrophy: Even if you're comfortable with your programming skills now, relying on AI for mundane tasks can lead to forgetting important skills over time. Without regular practice, your coding abilities may decline.

3. Dependence on AI: Early exposure to AI tools can create a dependency, especially for new programmers. This might lead to a future where they can't code without AI assistance, limiting their development.

4. Legal Issues: There are unresolved legal questions about the ownership of AI-generated code. Concerns exist about using code that may include copyrighted material from its training data.

5. Lack of Respect: Code generated by AI may not earn you respect as a programmer. True pride comes from creating your own solutions, rather than relying on AI.

6. Alternatives for Using AI: Some may prefer AI if they dislike coding or want to shift their focus to reviewing code instead. However, this suggests a lack of genuine interest in programming.

In essence, the article emphasizes the importance of actively engaging in coding to maintain and develop your skills, rather than relying on AI to do the work for you.

Texas is suing five major TV manufacturers—Sony, Samsung, LG, Hisense, and TCL—accusing them of secretly recording what people watch in their homes. Attorney General Ken Paxton claims these TVs use a technology called Automatic Content Recognition (ACR) to gather personal data for targeted advertising.

The lawsuit alleges that ACR can capture not just what’s on the TV but also streams from security cameras and other connected devices. Paxton argues that the companies mislead users into enabling ACR, and they collect viewing data without consent. He also raises concerns that TCL and Hisense, being Chinese companies, could be involved in surveillance.

Paxton is asking the court to impose penalties and stop these companies from collecting and selling data from Texas consumers. He emphasizes the importance of privacy and consumer rights, stating that owning a TV shouldn't mean giving up personal information to large tech companies or foreign entities.

Summary: Building a Transparent Keyserver

On December 19, 2025, a new keyserver was created to securely look up age public keys. This keyserver uses transparency log technology to ensure that the operator cannot secretly add harmful keys while still protecting user privacy. The final product can be accessed at keyserver.geomys.org, and its development involved the collaboration of various teams and years of effort.

Key Points:

1. Purpose: The goal is to provide a secure and user-friendly way to fetch public keys associated with email addresses. Users can log in to set their keys, and others can look them up.

2. Transparency and Accountability: The keyserver employs transparency logs, which are append-only lists that provide cryptographic proofs of the data's authenticity. This means users can verify that the keys are legitimate and not tampered with.

3. Privacy Concerns: To protect privacy, the keyserver uses Verifiable Random Functions (VRFs) to hash email addresses, preventing direct visibility of users' emails in the logs.

4. Anti-Poisoning Measures: To avoid malicious entries, the server stores hashes of public keys in the logs instead of the keys themselves, keeping the actual keys in a secure database.

5. Monitoring and Verification: Users can monitor the log to ensure no unauthorized keys are linked to their email addresses. A new API allows checking VRF proofs without exposing actual email addresses.

6. Witness Network: The keyserver uses a network of witnesses to ensure consistent log entries, preventing the operator from providing different views of the log to different users.

7. Future Development: Plans are in place to improve monitoring efficiency and revocation processes, with new designs expected to be ready by late 2026.

In total, implementing the keyserver and its transparency features involved fewer than 500 lines of code, preserving user experience while enhancing security and accountability.

The author shares their frustrating experience with confusing CPU naming schemes. After upgrading an old Dell workstation with Proxmox, they tried to replace the original Intel Xeon E5-1650 v2 CPU with a newer Xeon E7-8890 v4 CPU, both of which were supposed to fit the same FCLGA2011 socket. However, they discovered that the newer CPU actually uses a different variation of the socket called Socket R2, while their workstation uses Socket R. This naming confusion led to the new CPU not fitting, leaving the author with an unusable part. They criticize Intel's naming system for not being clear and note that they will keep the CPU in case they find a compatible motherboard in the future. Overall, while disappointing, the experience was not too costly.

Daniel, a 16-year-old high school senior, discovered serious security flaws in Mintlify, an AI documentation platform used by major companies. He found a critical vulnerability that could allow attackers to inject harmful scripts into documentation, potentially stealing user credentials.

His exploration began when Discord switched to Mintlify for their documentation. Daniel, experienced in finding vulnerabilities, looked for issues in the new system. He found an endpoint that allowed access to files from any Mintlify documentation but initially couldn't execute any malicious code.

After further investigation, he discovered another endpoint that returned static files. By cleverly using an SVG file to embed JavaScript, he successfully executed a cross-site scripting (XSS) attack through Discord's domain.

Upon finding this vulnerability, Daniel collaborated with friends who had also been investigating Mintlify. They reported the issue, prompting Discord to temporarily shut down their developer documentation while they assessed the risk. Mintlify quickly engaged with them to fix the vulnerabilities.

The attack could have affected many of Mintlify's clients, including Twitter and Vercel, putting their user accounts at risk. Daniel and his friends responsibly disclosed the vulnerabilities and earned around $11,000 in bounties for their findings.

On December 18, 2025, Apple provided access to a Mac Studio cluster for testing a new feature called RDMA over Thunderbolt in macOS 26.2. This feature allows multiple Macs to share RAM, improving the performance of large AI models. The cluster tested cost around $40,000 and included 1.5 TB of memory.

The Macs are powerful for both AI tasks and creative applications, using less than 250 watts of power. However, they are expensive, with individual units costing between $8,099 and $11,699. Compared to Nvidia and AMD systems with less memory, the Mac cluster offers competitive performance.

Setting up the Macs in a mini rack was made easier with a new enclosure from DeskPi. However, managing the Macs proved challenging due to limitations in macOS, such as the inability to perform system upgrades remotely via SSH.

Testing showed that while a single M3 Ultra Mac Studio outperformed competing systems, clustering four Macs did not significantly speed up performance due to memory limitations. Stability issues were noted with the new RDMA feature, which performed well when it worked but caused crashes at times.

The author expressed excitement about the potential for future improvements, including support for even larger models and better networking options. Overall, while the Mac Studio cluster shows promise for AI applications, it faces challenges in management and stability.

Summary of Durable Execution

Durable execution refers to a method of managing and orchestrating tasks in software systems, particularly in environments where tasks are long-running or complex. The author shares their journey in understanding durable execution while developing task orchestration systems.

1. Task Queues: Most applications start with simple APIs, but when tasks become resource-intensive or time-consuming, a task queue is introduced to handle them in the background. This helps keep the application responsive.

2. Message Brokers: To prevent message loss when workers crash, a message broker is used as an intermediary between the application and the workers. This adds reliability to task processing.

3. Idempotency: This concept means that tasks can be repeated without changing the outcome. Simple tasks are often idempotent, making them easier to manage.

4. Complex Tasks: More complicated tasks, like provisioning cloud resources, can be less straightforward. They require managing intermediate states and multiple subtasks, which can complicate reliability.

5. Orchestration Engines: For managing complex workflows, orchestration engines like Temporal help maintain the state of tasks, allowing them to be retried or resumed after failures.

6. Durable Execution Properties:

   • Retries: Workflows can retry until they complete successfully.
   • Idempotency: Each subtask is executed exactly once, ensuring consistent processing.
   • Determinism: The order of tasks must remain the same across retries to avoid errors.

7. Advantages of Durable Execution:

   • It guards against unexpected failures by allowing tasks to resume from the last saved state.
   • It enables the creation of complex workflows programmatically, which can adapt to different conditions.
   • It can skip resource-intensive tasks if they have already been completed previously.

8. Limitations: Durable execution is not a cure-all. It’s important to address underlying issues causing failures and to recognize that not all systems need durable execution, as simpler task queues may suffice.

The author encourages exploring durable execution solutions for workloads that may benefit from improved task management and reliability.

Key Points:

1. What is Prompt Caching?

   • Cached input tokens are significantly cheaper than regular ones.
   • Caching helps speed up the response time when using long prompts.

2. How Does It Work?

   • LLMs function as complex mathematical models that process input (text) and produce output.
   • The process involves several stages: tokenization, embedding, and the transformer mechanism (including attention).

3. Tokenization and Embedding:

   • Tokenization converts text into tokens (numerical representations).
   • Embeddings are multi-dimensional representations of these tokens, allowing the model to understand relationships and meanings.

4. Transformer Mechanism:

   • The attention mechanism determines the importance of each token in relation to others, enabling the model to generate contextually relevant output.
   • By caching the K (key) and V (value) matrices during inference, the model avoids recalculating values, making processing faster and cheaper.

5. Benefits of Caching:

   • Providers can store K and V matrices for reuse, significantly reducing costs and improving response times.
   • Both OpenAI and Anthropic use different methods for caching, with Anthropic allowing more user control.

6. Conclusion:

   • The advancements in prompt caching highlight the evolving capabilities of LLMs and suggest that the technology has much more potential to explore.

Summary: Designing a Passive LiDAR Detector Device

Samy Kamkar's talk at DEF CON 32 inspired the design of a device to detect LiDAR signals from iPhones, particularly the iPhone 15 Pro. LiDAR is activated when the camera app opens, allowing detection of this signal even before a picture is taken.

Key points include:

1. LiDAR System: The iPhone's TrueDepth system uses a 60Hz infrared signal, which can be recognized through cameras without IR filters. This system can also identify when the device is unlocked or when FaceID is activated.

2. Detection Challenges: Initial doubts about the feasibility of creating a small detection device led to further research and experimentation. Understanding the signal characteristics was crucial.

3. Hardware Requirements: The device needs to detect 940nm infrared signals efficiently. Various methods were tested, including using photodiodes and bandpass filters, with the best results coming from 940nm peak photodiodes.

4. Signal Processing: The device must process signals quickly to distinguish the LiDAR signal from background noise. A Schmitt Trigger was selected for its speed and reliability in detecting 60Hz signals.

5. Design Iterations: Several designs were tested, including using op-amps and comparators for signal processing. The final decision favored the Schmitt Trigger version due to its performance.

6. Next Steps: Future work will involve developing firmware for the hardware and exploring how to differentiate LiDAR signals from other sources.

Overall, the project aims to create a device that effectively detects and analyzes LiDAR signals from smartphones.

I have successfully created generic functions for Axe. The implementation took some time, but now everything is working. I have also attached the documentation, repository, and site for reference.

The author has released the reconstructed source code for the first three episodes of Commander Keen, coinciding with Keen's 35th anniversary. This package includes all known versions, from a 1990 beta to the lesser-known version 1.34. To compile the code into exact copies of the original games, users will need specific versions of Turbo C++ and Turbo Assembler.

The reconstruction was primarily done in early 2021 but faced challenges due to the lack of the correct compiler. The author created a method to ensure variable order in the code using a random naming technique.

Additionally, the author mentions that some code used in the project came from other games, raising questions about the rights to that code. The author encourages readers to explore the released code.

The drag and drop feature can be challenging, especially on mobile devices, because it requires multiple actions at once, which often leads to mistakes. To improve this, I created a simpler two-step method: selecting an item and then placing it. This approach may take longer than traditional drag and drop but is easier for those who find it hard to hold down the mouse button. The tool I developed, called picknplace.js, allows users to select an item with two clicks and some scrolling. This is still an experimental solution, and I'm interested in feedback.

Sure! Please provide the text you'd like me to summarize.

The text discusses the responsibilities of software engineers in the context of using AI tools for coding. Here are the key points:

1. Responsibility: Software engineers must deliver code that they have tested and proven to work, rather than relying on others to fix their untested code.

2. Proving Code Works: There are two essential steps to show that code works:

   • Manual Testing: Engineers should manually test their code to ensure it functions correctly and demonstrate this to reviewers. This can include providing terminal commands or screen recordings.
   • Automated Testing: Engineers should also write automated tests that confirm the code works and will continue to work in the future. Skipping manual testing for automated tests is not advisable.

3. Using Coding Agents: With the rise of coding agents like Claude Code and Codex CLI, engineers should also ensure these tools manually test and create automated tests for their changes.

4. Human Accountability: Ultimately, it is the engineer's responsibility to ensure the code is proven to work, as computers can't be held accountable.

In summary, engineers should focus on delivering well-tested code and take full responsibility for proving its functionality before submitting for review.

Summary:

A software engineer, KR Krishiv Dakwala, describes how Property-Based Testing (PBT) identified a security vulnerability in a chat application’s API key storage system that traditional tests missed. The application was built using AI, and during testing, a specific input "proto" led to a failure in a round-trip property test, revealing a flaw in how JavaScript handles prototypes.

Key Points:

• Security vulnerabilities can hide in untested corners of code.
• Traditional unit tests often focus on expected inputs, missing edge cases.
• PBT tests various inputs randomly, uncovering issues like the one found with "proto".
• The flaw could potentially allow an attacker to manipulate the prototype if not addressed.
• Kiro implemented two fixes to prevent this vulnerability.
• This case shows the effectiveness of PBT in finding hidden bugs and ensuring software security.

The author reflects on their past experiences with ring buffer implementations, realizing they had been using an inefficient method. A ring buffer is a data structure that uses a fixed-size array for storing elements, allowing for efficient reading and writing operations.

Key Points:

1. Common Implementations:

   • The traditional method uses an array with two indices (read and write). However, this approach wastes one element, meaning an array of size 4 can only hold 3 elements.
   • An alternative uses one index for reading and a separate length field to track how many elements are in the buffer, allowing full usage of the array but complicating concurrent access.

2. Proposed Solution:

   • The author suggests a more efficient implementation using two indices without masking them during increment operations. Instead, they only apply a mask when accessing the array, which eliminates the wasted slot while keeping the code simple.

3. Considerations:

   • This method requires the array capacity to be a power of two and relies on the programming language’s support for unsigned integer overflow to function correctly.
   • The author questions why many still use the less efficient methods, suggesting it may be due to tradition or lack of revisiting the topic.

4. Conclusion:

   • The author plans to explore other common misconceptions in programming, hinting at future discussions on related topics.

Overall, the article emphasizes the importance of understanding and optimizing data structure implementations for better efficiency.

The author reflects on the importance of a unique digital identity, which leads them to consider getting a personalized license plate after receiving reminders from the DMV. They discover a hierarchy of license plate rarity and find that Florida has a user-friendly website to check plate availability.

The author, an engineer, automates the process of checking license plate combinations using a script, as the website does not have limits on the number of requests. They create a microservice to track availability in real time and build a frontend to visualize the data.

After successfully finding a rare two-letter combination, "EO," the author rushes to the DMV only to find it has been taken. However, after checking again, they spot another rare combination, "HY," which they manage to reserve after a wait at the DMV. They conclude that with determination and some coding skills, one can successfully obtain unique license plates.

The Central Pangean Mountains were a large mountain range that existed during the Carboniferous, Permian, and Triassic periods when the supercontinent Pangaea was formed. This mountain chain connected areas we now know as the Scottish Highlands, the Appalachians, the Ouachita Mountains, and the Little Atlas in Morocco. The mountains were created from the collision of the supercontinents Laurussia and Gondwana.

Throughout the Permian period, the mountains experienced significant erosion, which reduced their height and created deep valleys. By the Middle Triassic, they had shrunk considerably, and by the beginning of the Jurassic period, much of the range in Western Europe had disappeared, leaving behind highlands separated by deep sea basins.

Summary of Rust's Block Pattern

John Nunley introduces a coding pattern in Rust called the "block pattern," which he believes can make Rust code cleaner and more robust. This pattern takes advantage of the fact that blocks in Rust can be used as expressions.

Key Points:

1. Understanding the Block Pattern:

   • A block in Rust can encapsulate multiple statements and can return a value. For example, using a block to compute a value is equivalent to directly assigning that value.

2. Example Scenario:

   • A function that loads and processes a configuration file can become cluttered with variable declarations. In a typical implementation, many variables may be declared but only one is used later.

3. Improved Code Organization:

   • By using the block pattern, you can group related code together, making the intent clearer and reducing variable pollution. For instance, all configuration loading and parsing can be done within a single block.

4. Advantages of the Block Pattern:

   • Clarity: The purpose of the code is clear from the start.
   • Namespace Management: Reduces the number of variables in the outer scope, making it less error-prone.
   • Resource Management: Variables that are only needed temporarily go out of scope after the block, freeing up resources.

5. Mutability Control:

   • The block pattern also helps limit the scope of mutable variables, reducing the risk of unintended changes.

Conclusion:

The block pattern is a useful idiom in Rust that can enhance code readability and maintainability. Although not widely recognized, it offers practical benefits for both novice and experienced Rust developers.

Summary of Egyptian Hieroglyphs: Lesson 1

General Overview:

• Egyptian hieroglyphs are a flexible writing system that can be arranged in columns or rows and read from either direction.
• To determine the reading direction, look for hieroglyphs with faces; read towards them.

Transliteration and the Alphabet:

• Transliteration converts one script into another; hieroglyphs can represent single, double, or triple consonant sounds.
• The hieroglyphic alphabet has no vowels, making pronunciation difficult. A basic rule is to add an "e" between consonants to vocalize words.

Pronunciation:

• Each hieroglyph has a specific sound. For example,𓄿 (3) is pronounced as "ah" and 𓇋 (i, j) as "ee".

Types of Hieroglyphs:

1. Ideograms: Represent ideas or concepts (e.g.,𓁷 for "face").
2. Phonograms: Represent sounds and can be combined to form words (e.g.,𓂋𓈖 for "name").
3. Determinatives: Provide context but do not have a phonetic value (e.g., a leg at the end of a word suggests movement).

Memorization:

• Engaging with hieroglyphic texts will help you remember common signs and words over time. Flashcards can aid in memorization.

Exercises:

• The lesson includes exercises to practice reading hieroglyphs in the correct direction and translating them.

This lesson introduces the basics of reading and understanding Egyptian hieroglyphs, including how to recognize and pronounce them, and the different types of glyphs used in the writing system.

The military standard mil-std-882e outlines four levels of software control based on the potential danger of the software's actions:

1. Highest Risk: Software directly controls something that can immediately cause harm if it fails.
2. Moderate Risk:
   • The software has direct control but there's a delay before it causes danger.
   • The software is not in direct control, but a human must quickly respond to its signals to avoid danger (e.g., shutting down a reactor in a critical situation).
3. Lower Risk: The software is not in direct control, and there's time to verify its recommendations independently before taking action.
4. Lowest Risk: The software has an auxiliary role and does not control anything critical.

This framework is particularly relevant now as advancements in technology allow software to play a larger role in processes that were once entirely human-operated.

The Pennsylvania Supreme Court recently ruled on whether individuals have Fourth Amendment rights regarding their Google search terms in the case of Commonwealth v. Kurtz. The ruling found that these rights do not apply, with three Justices agreeing that the traditional third-party doctrine means people have no expectation of privacy in information shared with companies like Google.

In this case, police obtained a warrant to access Google search records to identify a suspect in a sexual assault. They tracked searches for the victim's name and found a match to the defendant, Kurtz. Kurtz challenged the warrant, arguing it lacked probable cause, but the court maintained that the lack of privacy expectation in search terms rendered this irrelevant.

The court compared internet usage to cell phone use, highlighting that while cell phones create involuntary data trails, internet usage is voluntary. Users choose to input data, thus willingly sharing it with third parties. Google explicitly informs users that their search data may be shared with law enforcement, further negating any claims of privacy.

One Justice expressed a different viewpoint but did not formally take a position on the privacy question, while another Justice dissented, arguing that the internet's role in modern life is similar to that of cell phones and should afford some privacy protections under the Fourth Amendment.

This ruling contrasts with a recent decision by the Colorado Supreme Court, which found that accessing search terms constitutes a Fourth Amendment search, based on similar arguments regarding Google's terms of service. Overall, the Pennsylvania court concluded that users do not have an expectation of privacy when conducting searches on Google.

Summary of "How I wrote JustHTML using coding agents"

Emil Stenström shares his experience creating JustHTML, a Python-based HTML5 parser that successfully passed all tests from html5lib, has no dependencies, and features a CSS selector query API. The project taught him about using coding agents effectively.

Initially, he underestimated the complexity of parsing broken HTML5 code, particularly the challenging "adoption agency algorithm." He realized that choosing projects with existing tests is beneficial for coding agents to track progress.

The development process was iterative, starting with a basic parser that struggled, but gradually improved to 100% test coverage through refactoring and bug fixes. He used tools like VS Code and GitHub Copilot's Agent mode, allowing the agent to work autonomously while he managed high-level decisions.

After achieving correct parsing, performance became a focus. Despite attempts to speed up the parser, including rewriting parts in Rust, the parser remained slower than existing options. Eventually, he decided to restart the project, this time aiming to port logic from a fast Rust parser (html5ever) to Python, leading to a fresh iteration that still faced speed challenges.

Stenström employed profiling and micro-optimizations to enhance performance, alongside using a fuzzer to ensure robustness against edge cases. Ultimately, JustHTML emerged as a strong parser, surpassing other libraries in test coverage.

He emphasizes the importance of clear goals, code review, and the right balance of oversight when working with coding agents. Despite the quick progress with the agent handling most coding tasks, he played a crucial role in design decisions and guiding the project.

Samsung has announced the Exynos 2600, the first mobile chip built using a 2 nanometer process. This new chip aims to enhance performance and efficiency for high-end devices like the upcoming Galaxy S26 series. It features a 10-core ARM-based design, promising up to 39% better CPU performance and 113% faster AI processing. The graphics performance is also significantly improved, with a GPU that doubles previous capabilities.

To overcome past issues of overheating, Samsung has implemented a new heat management system called Heat Path Block (HPB), which helps maintain performance during heavy use.

Apple is expected to launch its own 2nm chips in 2026, using TSMC's technology. These chips, including the A20 for the iPhone 18, will offer better performance and energy efficiency compared to current models. Apple's first 2nm chips could also be featured in future Macs.

Summary of "Introducing Ringspace: A Proposal for the Human Web"

The author expresses frustration with the decline of the internet, recalling nostalgic memories of early online experiences. They argue that the internet's original promise of connection and access to knowledge is fading. Instead of just lamenting the situation, they propose a solution inspired by the past: the concept of webrings.

Webrings were simple groups of linked websites that shared a common focus, built on trust among creators. The author suggests modernizing this idea to create a platform called Ringspace, which aims to foster trust within small communities of content creators. Ringspace uses a command-line interface and a browser extension to verify the identity and credibility of websites within its network.

The goal is to reclaim the human element of the internet and encourage genuine connections. The author invites feedback on the Ringspace concept, emphasizing that no artificial intelligence was involved in its creation and encouraging community input for its development.

The Linux version of Superluminal, a CPU profiler, uses eBPF (extended Berkeley Packet Filter) to gather performance data. This led to a significant improvement in how updates to eBPF maps, particularly map-in-map types, are handled in the Linux kernel.

Key Points:

1. What is eBPF?
   eBPF is a feature in the Linux kernel that allows custom programs to run safely within the kernel, reacting to specific events. Superluminal uses it to monitor performance metrics like context switches.

2. eBPF Maps:
   Data is exchanged between the kernel and user space via eBPF maps, which are shared memory structures. Superluminal uses these maps to transfer performance data, including stack backtraces.

3. Performance Bottleneck:
   During profiling, it was discovered that the function bpf_map_update_elem, which updates eBPF maps, was causing significant delays due to a synchronization mechanism (synchronize_rcu) that blocks until all references to the old value are cleared. This led to a performance issue when multiple threads attempted to update maps simultaneously.

4. Optimization Discovery:
   By profiling the profiler, the team identified that the delays were primarily due to this blocking operation, which significantly slowed down the data upload process. The synchronization was essential for ensuring data integrity but was excessively costly in terms of performance.

5. Kernel Code Changes:
   The team proposed and implemented a change to the kernel that modifies how updates to map-in-map types are handled, making the process much faster (31 times faster in tests). This change will be included in the upcoming Linux kernel release (6.19).

6. Conclusion:
   The profiling work not only improved Superluminal's performance but also contributed to the Linux community by enhancing eBPF functionality, demonstrating the value of thorough performance analysis that includes both active and waiting states in profiling.

The project started with a JavaScript image difference tool, but to improve its speed, the core was rewritten in Rust. This new version is the fastest open-source tool for single-threaded image differences, processing 4K images in about 327 milliseconds, compared to 1215 milliseconds with the previous tool, odiff. The new binaries are also smaller, around 700KB instead of 2MB.

The key improvement was making the initial analysis (cold pass) smarter. Instead of checking every pixel, it scans blocks of pixels to identify "problematic" areas that might have differences. The detailed analysis (hot pass) is then only applied to these areas, which speeds up the process. The tool uses efficient image processing libraries and supports various hardware optimizations. It can seamlessly replace odiff while maintaining the same interface.
