Heathrow Airport has lifted the limit on liquid container sizes, allowing passengers to bring liquids in containers up to two litres through security. This change comes after the installation of new CT scanners at all terminals, which also permit laptops to remain in bags. Although Heathrow is the largest airport to implement this upgrade, other UK airports like Gatwick, Edinburgh, and Birmingham have already done so.

The new rules mean passengers no longer need to use clear plastic bags for liquids, but they should check the restrictions at the airports they are returning from. Despite the advancements, some airports with new scanners are still waiting for approval from the Department for Transport to increase their liquid limits from the traditional 100ml.

The transition to these new security measures faced delays, with past promises to abolish the 100ml rule not being met due to various setbacks, including the pandemic. A recent report noted that the new scanners may lead to more hand searches of bags. Heathrow’s upgrades aim to enhance efficiency and security for travelers.

However, confusion persists among passengers due to varying rules at different airports, prompting calls for clearer communication about security requirements.

In 2026, a troubling trend called "Pump and Dump" software emerged in the crypto world. This started after 2025, when creating software became easier thanks to advanced AI. Many people wasted money on poorly functioning software with no clear purpose.

One example of this was a browser called Cursor, which spent millions on a product that couldn’t be completed or used effectively. Companies began using hype to inflate their value rather than creating real products.

A project called "gastown" caught attention for being poorly designed yet marketed as revolutionary, leading to suspicions of crypto scams. Here’s how the scam works:

1. A tech person creates subpar software using AI and invests in crypto tokens.
2. Unable to sell the product, they partner with crypto enthusiasts who incentivize them with tokens.
3. The project is heavily promoted online, often through fake support.
4. Developers try the software due to excitement in the tech community.
5. Eventually, the product fails, and the associated crypto tokens are sold off, leaving many investors with worthless assets.

Recently, a project named Clawdbot has been hyped up, but it appears to be another unreliable venture. Investors are encouraged to be cautious and critical, as many promotional posts may be misleading. It’s important to avoid getting caught up in the hype and to recognize that some projects may not be sustainable.

Summary:

Mathematicians have solved a long-standing question in topology known as the Bonnet problem, which asks if a small amount of local information can uniquely identify a surface. For over 150 years, it was believed that compact surfaces (like spheres and doughnuts) could always be defined by this local data. However, researchers Alexander Bobenko, Tim Hoffmann, and Andrew Sageman-Furnas recently discovered two twisty, closed surfaces that share the same local information yet have different global structures, proving that this assumption was incorrect.

The team used both discrete and smooth geometric methods to explore this problem. Initially, they focused on discrete surfaces, akin to pixelated shapes, which allowed them to computationally experiment and generate examples. After finding a promising discrete shape, they adapted their findings to smooth surfaces, ultimately creating two distinct tori (doughnut shapes) that met the criteria of the Bonnet problem.

This discovery indicates that even well-studied surfaces like tori cannot always be uniquely defined by their local properties, challenging previous mathematical intuitions. The researchers hope this breakthrough will lead to a deeper understanding of geometry and topology.

Summary: Handling Long Branches in Programming

In programming, branch instructions often have a limited range based on the architecture. When a target function is too far away, special techniques are needed to handle the branch correctly. For example, in the AArch64 architecture, a function call from one location to another over 128 MiB apart cannot be performed directly and requires special handling from the compiler, assembler, and linker.

Key Points:

1. Branch Range Limitations:

   • Different architectures have different maximum ranges for branches. For instance:
     • AArch64: ±128 MiB for unconditional branches, ±1 MiB for conditional branches.
     • x86-64: Up to ±2 GiB for both types.
     • Other architectures like AArch32, PowerPC, and RISC-V have their own specific limits.

2. Toolchain Coordination:

   • Compiler: Identifies out-of-range branches and modifies them to fit within the limits (e.g., inverting conditions and adding unconditional jumps).
   • Assembler: Converts assembly code to machine code, selecting appropriate instruction encodings based on known distances during assembly.
   • Linker: Resolves and fixes out-of-range branches after the complete layout is determined, often by creating "thunks" (small pieces of code that redirect to the actual target).

3. Thunk Types:

   • Short Range Thunks: Simple redirection within a limited range.
   • Long Range Thunks: Use address computation to reach far targets, allowing jumps to almost any location.

4. Linker Relaxation (RISC-V):

   • RISC-V can also shrink instruction sequences when branches are close enough, saving space in the final code.

5. Diagnosing Errors:

   • If a "relocation out of range" error occurs, check the error message for details, consider using options to generate a link map, and look at function placements to minimize distances.

Conclusion:

Handling long branches effectively involves collaboration between the compiler, assembler, and linker, each contributing techniques to ensure correct execution across various architectures. RISC-V is notable for its ability to both expand and shrink code at link time, optimizing for size and correctness.

The person wants to learn Assembly language to create games for the Apple II. They are looking for old books that teach 6502 Assembly and details about the Apple II, like memory and screen management. They also want to know if it's essential to learn BASIC before starting with Assembly.

The text discusses the challenges and complexities in package management, particularly the differences between system package managers (like apt and dnf) and language package managers (like npm and pip). Both types of managers handle dependencies and install software, but they evolved to meet different needs, leading to conflicts, especially around C libraries.

Key points include:

1. Different Purposes: System package managers are designed for delivering applications and managing shared libraries, while language package managers focus on helping developers build projects with specific dependencies.

2. Dependency Handling: System package managers typically keep only one version of each package, simplifying dependency management but complicating the installation of different versions. Language package managers allow users to keep multiple versions and specify exact dependencies.

3. Lack of Universal C Package Management: The C ecosystem lacks a standard package registry, leading to fragmented dependency management. This means that when language packages depend on C libraries, they often have to rely on system package managers, which creates compatibility issues.

4. Phantom Dependencies: Many packages bundle dependencies without clearly representing them in metadata, making it hard to track what libraries are actually being used.

5. Existing Solutions: Tools like Conda attempt to bridge the gap by managing dependencies across languages, but they aren't universally adopted. Other tools like Nix and Guix offer methods to map language packages to system libraries, but still don't fully solve the communication issue.

6. Proposed Automation: There’s a movement to automate the mapping of symbols from binaries to system libraries, helping to make hidden dependencies visible. This could improve sustainability and security by showing relationships between packages and their underlying libraries.

The author emphasizes that addressing these cross-ecosystem dependencies is essential for improving package management and ensuring that contributions are recognized and supported.

The text discusses how to modify a SQL database while preserving the behavior of existing code.

1. Migration from Boolean to Timestamp: Initially, a user table has a non-nullable is_activated boolean column. To change this to a nullable activated_at timestamp column, you can update queries to set is_activated to the current date instead of true. A refinement mapping allows new code to use the new structure while legacy code continues to function as before.

2. Transition to Event Sourcing: The next step involves switching to an event sourcing model where user actions (like activation and deactivation) are recorded in a user_events table instead of just a timestamp. Again, updates to queries can be made while keeping existing code intact through another refinement mapping.

3. Mutability Constraints: The author introduces constraints to ensure that certain properties remain unchanged despite modifications. For example, if a user is activated, they should remain activated after changes. However, the new event sourcing model complicates this as it allows deactivation through new events.

4. Refinement Challenges: The text highlights that not all proposed refinements hold under new conditions, showing that the process can be complex.

5. Learning Refinement: The author suggests that understanding refinement is challenging, especially when combined with formal methods. They propose teaching it in a more familiar context, like databases, to improve comprehension.

The article discusses the impact of LED lighting (350-650 nm) on human visual performance and metabolism. It highlights that life evolved under broad-spectrum sunlight (300-2500 nm), which is important for physiological functions. However, modern LED lights, primarily emitting shorter wavelengths (350-650 nm), can negatively affect mitochondrial function, which is crucial for energy production and overall health.

Research shows that exposure to longer wavelengths (400-1500 nm), similar to daylight, can improve visual performance, specifically color contrast sensitivity. In a study, participants working under LED lighting experienced significant improvements in visual performance after being supplemented with incandescent lighting for two weeks. These improvements lasted for months after the incandescent lighting was removed.

The findings suggest that the restricted spectrum of LED lighting could lead to broader health issues, particularly for the elderly or in clinical environments. The study proposes that switching to broader spectrum lighting could be an economical way to enhance public health.

In summary, the article emphasizes the need to reconsider lighting choices in our environments to support better visual performance and overall health.

Summary

Problem Overview:
When users search for items like music albums, they often use messy input that doesn't match the clean data in a database. For example, users might type "beatles abbey rd" instead of "Abbey Road." To effectively match these queries, more advanced techniques are needed beyond simple database searches.

Dataset Used:
The article utilizes a dataset of over 114,000 Spotify tracks, which includes messy album names, making it ideal for testing matching approaches.

Two Matching Approaches:

1. Fuzzy Matching with pg_trgm:

   • This PostgreSQL extension analyzes character sequences (trigrams) to find similarities, making it effective for handling typos, abbreviations, or word order variations.
   • For example, it can correctly match "abbey rd" with "Abbey Road."

2. Semantic Search with pgvector:

   • This extension uses vector embeddings to assess meaning, allowing for matches based on synonyms or conceptual similarities rather than exact wording.
   • For instance, it can connect "Beatles final album" to "Abbey Road" even though the wording is different.

Text Normalization:
To improve matching accuracy, the text input from users and the catalog entries are cleaned through a normalization process. This involves removing unnecessary details and standardizing terms, which helps both fuzzy matching and semantic search perform better.

Hybrid Search Strategy:
The best results come from combining both approaches: starting with fuzzy matching for speed, and falling back to semantic search if the initial match isn't strong enough.

Conclusion

Using these techniques, you can effectively match messy user input with structured data in a database. The article provides a way to implement these methods in PostgreSQL without needing complex infrastructure.

The study looks at the strategic complexity of 960 Chess960 (Fischer Random Chess) starting positions. It finds that White generally has an advantage on the first move, with an evaluation of about +0.30 pawns. To measure how difficult decisions are in these openings, researchers created a method called S(n), which calculates the information needed to find the best moves. This method separates the contributions of White and Black, leading to a total complexity score and a measure of decision imbalance.

The overall complexity varies significantly, while the imbalance in decision difficulty ranges from -2.5 to +1.8 bits. On average, White faces slightly tougher decisions. The standard chess starting position is notably asymmetric, ranking in the 91st percentile for imbalance but average in overall complexity. The most complex opening is identified as #226, while #198 is the most balanced. The findings show that even small changes in piece arrangement can greatly affect strategy and fairness in Chess960, with the traditional chess setup not being the most balanced configuration.

All InCheck helps assess real commitment after meetings. Create a session, share a link, and ask team members if they would defend the decision. It reveals any hesitation before moving forward, ensuring true agreement.

The text emphasizes the importance of engaging the reader right from the start when writing nonfiction. It criticizes typical introductions that provide dull historical background without sparking curiosity. Instead, writers should create interest by presenting compelling questions or surprising facts that provoke the reader's curiosity.

Using Venice as an example, the author shows how to capture attention by highlighting the paradox of a powerful maritime empire that lacked agricultural land, summarizing it in a catchy title like "Empires Without Farms." This approach encourages readers to think about how such an empire functioned and invites them to explore the topic further.

The key takeaway is that to keep readers engaged, writers should start with what makes the topic intriguing, ensuring that their introduction promises an interesting exploration of the subject. The main advice is clear: first, make the reader care.

Summary of "A History of Haggis"

The origins of haggis, a dish often associated with Scotland, are unclear and debated. Some theories suggest it was introduced by the Romans, Vikings, or even the English. In 2009, a food historian claimed to have found a 1615 cookbook indicating haggis might be of English origin, which upset many Scots.

Haggis likely began as a way to preserve meat using offal, with early mentions of similar dishes found in England, dating back to the 14th century. However, by the 18th century, haggis was more common in Scotland, where it remained a popular and affordable dish as the English diet evolved.

Political tensions between England and Scotland, especially after the Jacobite Risings, led to haggis being viewed as a distinctly Scottish dish. The Scots embraced this identity, particularly through Robert Burns’ poem “Address to a Haggis,” which celebrated the dish as emblematic of Scottish strength.

In the 19th century, King George IV's visit to Scotland helped popularize haggis as a national symbol, leading to a renewed interest in Scottish culture, including haggis at celebrations. Today, while the exact origins of haggis remain debated, it is firmly established as a key part of Scottish identity.

In a decade of being an engineering manager, Jampa Uchoa shares valuable insights that he wishes he had learned earlier. Here are the key takeaways:

1. Flexible Role: The role of an engineering manager varies widely based on team needs and circumstances. It's not a defined position but requires adaptability across four areas: Product, Process, People, and Programming.

2. Product Ownership: Everyone on the team should understand the product and its value to users. Working on features without clear user benefits can lower morale and lead to failure.

3. Process Awareness: Processes should be continually assessed to ensure they add value. Rigid adherence to outdated processes can hinder productivity and focus on outcomes.

4. Transparent Communication: Managers should be honest with their teams. Transparency builds trust, while withholding information can lead to resentment.

5. Strategic Upward Communication: When communicating with executives, managers must present clear, well-thought-out options instead of vague ideas to avoid misguided decisions.

6. Management Balance: A manager's role consists of 10% being a player (doing technical work), 30% coaching team members, and 60% providing encouragement and support.

7. Empowerment: Managers should work towards making their teams independent so that they can thrive without constant oversight.

8. Trust Building: Trust is crucial for a successful team. Managers should believe in their team's abilities and help them improve when necessary.

9. Verification: While trusting team members, managers should monitor progress to provide support and accountability.

10. Delegation: Managers should delegate tasks and avoid holding onto projects unnecessarily, allowing team members to learn and grow.

11. Risk Management: Being cautious is important, but over-correcting for risk can lead to worse outcomes. A balanced approach to risk is essential, especially in hiring practices.

Jampa encourages other managers to reflect on their experiences and share insights.

Paul Kinlan, a web platform developer advocate at Google, is exploring how web browsers can serve as a safe environment (or "sandbox") for running untrusted code. He created a demo called Co-do to test the idea of building applications like Cowork in the browser.

Key points from his research include:

1. Sandbox Features: The browser has three critical features for this sandbox: filesystem access, network access, and safe code execution. These can be managed using technologies like the File System Access API, Content Security Policy (CSP) with <iframe sandbox>, and WebAssembly in Web Workers.

2. Co-do Demo: Co-do allows users to select a folder of files and connect to a language model provider through a chat interface, without needing heavy local containers for the sandbox.

3. Documentation Challenges: Kinlan notes that documentation for <iframe sandbox> is lacking, especially across different browsers, but he shares useful techniques and insights in his post.

4. New Discoveries: He highlights the <input type="file" webkitdirectory> tag, which enables browsers to access a full directory of files, and he plans to use this feature in future projects.

Overall, Kinlan's work shows the potential for browsers to support more complex applications while maintaining security.

In Jorge Luis Borges' story "On Exactitude in Science," he describes a fictional empire where cartography becomes so advanced that a map of a single province takes up an entire city, and a map of the entire empire is the same size as the empire itself. Over time, this detailed map is deemed useless by later generations who are less interested in cartography. They abandon the massive map, which eventually deteriorates and becomes ruins in the desert, inhabited only by animals and beggars. This serves as a reminder of the lost art of geography.

Summary: What "The Best" Looks Like in Hiring for Startups

When a startup receives funding, the new Chief Technology Officer (CTO) often faces the crucial decision of hiring the right talent. The common belief is that hiring the best candidates is essential for success. However, this notion is complicated by real-world constraints like limited budgets and competition from other companies.

Key Lessons:

1. Non-Obvious Talent: The best candidates often do not have the conventional credentials that larger companies seek. Startups should focus on finding hidden gems who may be overlooked by others.

2. Experience Balance: Ideal hires are usually mid-level, with enough experience to contribute significantly but not so senior that they require extensive management.

3. Hunger and Curiosity: Great hires are self-motivated, eager to learn, and driven by a passion for their work.

4. Humility: Successful team members acknowledge their mistakes, learn from them, and collaborate well with others.

5. Emotional Intelligence: High emotional intelligence (EQ) is crucial for teamwork and effective communication.

6. Team Players: Candidates should be proactive in their communication and collaborative in their work.

7. Competence: While skills are necessary, competence should be assessed through practical tests rather than just resumes.

8. Problem Solvers: Ideal hires are independent and resourceful, not just waiting for instructions.

9. Cross-Disciplinary Understanding: Great candidates appreciate the roles of other team members and anticipate their needs.

10. Tolerance for Uncertainty: Startups are unpredictable; hires must be adaptable and comfortable with change.

In conclusion, the definition of "the best" is subjective and varies by company. By focusing on these traits and looking beyond traditional qualifications, CTOs can build strong, high-performing teams that thrive in the startup environment.

The text discusses the challenges of achieving Linux binary compatibility using the musl C library and dynamic loading with Go and Godot. Here are the key points:

1. Background: Building command-line software for Linux is straightforward with Go, but issues arise when accessing hardware-accelerated graphics due to incompatibilities between libraries (glibc vs. musl).

2. Challenges with musl: The author encountered difficulties when compiling projects on a musl-based system, highlighting the need for better support for musl in Go.

3. Solution: The author created a new build option for musl in the graphics.gd project, allowing it to produce builds compatible with musl. However, users must create separate builds for glibc and musl.

4. Static Binaries: While musl supports static linking better than glibc, it does not support dynamic loading of libraries in static binaries. The author proposes a method to overcome this limitation using a small C program to interface with the system's dynamic linker.

5. Outcome: This approach allows for the creation of single static binaries that can run on various Linux systems with hardware graphics support.

6. Call to Action: The author provides a link to a sample project that can be tested on Linux and encourages others to try cross-compiling their projects using the new musl support.

In summary, the text focuses on making Linux software development easier by addressing the compatibility issues between different C libraries and how to effectively use Go and Godot together to produce functional binaries.

Summary of "Escaping VMware Workstation at Pwn2Own Berlin 2025"

At Pwn2Own Berlin 2025, researchers exploited a vulnerability in VMware Workstation, specifically in its PVSCSI controller, using a Heap-Overflow issue. This vulnerability allowed them to bypass security measures in Windows 11's Low Fragmentation Heap (LFH), which posed significant challenges during the exploit development.

Key Points:

1. Vulnerability Discovery: The main vulnerability (CVE-2025-41238) was found in the PVSCSI controller, which handles SCSI commands. An error in memory management allowed for out-of-bounds writes if more than 512 entries were provided by the guest OS.

2. Challenges with LFH: The LFH implemented strict security checks and random allocation, making it difficult to manipulate memory safely. The researchers had to create a specific heap layout to exploit the vulnerability effectively.

3. Exploitation Techniques: They used a technique called "Ping-Pong" to control memory allocation and ensure that their out-of-bounds writes targeted the right memory locations. They also leveraged the LFH's coalescing pass, which merged adjacent memory entries, to gain more control over memory.

4. Information Leak: To extract useful information, they corrupted fields in memory structures, enabling them to read from controlled memory locations and bypass security.

5. Arbitrary Operations: After obtaining control over memory structures, they developed read, write, and call primitives, allowing them to execute arbitrary code within the virtual machine.

6. Timing Channel: Just before the competition, they devised a method to predict the LFH state using timing differences in memory allocations. This allowed them to bypass unpredictable elements of the exploit.

7. Final Demonstration: The exploit was successfully demonstrated during the competition, showcasing their ability to escape from the virtual machine environment.

In conclusion, the research highlights the intricate process of exploiting a complex vulnerability in VMware Workstation, overcoming various security mechanisms, and the intense preparation leading up to the live demonstration.

This paper, published in Management Science, has been cited over 6,000 times by influential figures but contains serious flaws, and efforts to address these issues have largely failed.

Andy King details his struggle to replicate the study by Eccles, Ioannou, and Serafeim, which claims corporate sustainability enhances stock returns. He discovered significant problems, including incorrect statistical claims and a misleading methodology. Despite reaching out to the authors multiple times for clarification, he received no response.

King sought help from other scholars and the journal but faced resistance and rejection. The authors admitted to a typo regarding a significant finding but did not address the flawed methodology, which misrepresents the study's conclusions. King filed complaints to the authors' institutions, but these were dismissed as minor issues.

The paper remains only partially corrected, misleading thousands of readers. King emphasizes the need for reform in the scientific publication process to ensure accountability and integrity. He suggests that researchers should support replication efforts and correct errors openly.

Key recommendations include:

1. Avoid citing single studies as definitive.
2. Publish corrections for errors.
3. Encourage a culture that supports honesty in research.
4. Strengthen research integrity policies at institutions.

Ultimately, King argues that the current system for maintaining trustworthy science is broken and requires significant change.

Summary of Kubernetes Remote Code Execution Vulnerability

A security issue in Kubernetes allows unauthorized users with specific permissions (nodes/proxy GET) to execute commands in any Pod within the cluster. This was discovered on January 26, 2026, and is considered "working as intended" by the Kubernetes team, meaning it won't be fixed.

Key Points:

1. Vulnerability Overview:

   • The nodes/proxy GET permission allows code execution in any Pod when connected through the Kubelet API (port 10250).
   • This is due to a flaw in how Kubernetes handles authorization, especially during WebSocket connections.

2. Impact:

   • Attackers can exploit this to run commands in any Pod, including privileged system Pods, potentially compromising the entire cluster.
   • The Kubernetes AuditPolicy fails to log these unauthorized command executions.

3. Affected Versions:

   • Tested on Kubernetes versions v1.34 and v1.35.
   • Approximately 69 Helm charts (tools for managing Kubernetes applications) utilize nodes/proxy GET permissions, making them vulnerable.

4. Exploitation Method:

   • Attackers can connect to the Kubelet API using tools like websocat to execute commands without needing the CREATE permission.

5. Security Recommendations:

   • Kubernetes administrators should check service accounts for the nodes/proxy GET permission.
   • Restricting access to the Kubelet API can mitigate this risk.

6. Disclosure Status:

   • The vulnerability was reported but marked as "won't fix" due to the complexity of changing the underlying architecture.
   • Kubernetes plans to address similar issues in the future through a new feature called Fine-Grained Kubelet API Authorization (KEP-2862), but this is not yet Generally Available.

Conclusion:

This vulnerability poses a significant risk to Kubernetes clusters, especially in multi-tenant environments. Administrators should assess their security posture and consider restricting access to the Kubelet API to prevent unauthorized command execution.

In 2017, a French investigator revealed he was approached by an unnamed Israeli company at a security fair, which offered a geolocation tool using mobile phone advertising data. Almost ten years later, this technology has become part of a thriving industry called advertising intelligence (Adint). Currently, around 15 companies, mainly based in Israel and started by former intelligence and military members, provide services that allow intelligence and law enforcement agencies to track individuals using geolocation data from millions of mobile phones. This data is collected through various apps and sold for advertising purposes.

Last summer, the Electronic Frontier Foundation (EFF) asked a federal judge to stop the government from using Medicaid data to identify and deport immigrants. They expressed concerns about the Trump administration's plan to combine government data into a single, searchable system with the help of Palantir, a company criticized for its privacy practices.

Recent reports confirm these fears: Palantir is developing a tool for Immigration and Customs Enforcement (ICE) that uses various data sources, including Medicaid addresses, to identify potential deportation targets. This tool, called ELITE, helps ICE locate groups of people to detain.

The EFF warns that when government agencies share information for purposes beyond their original intent, it poses a serious threat to privacy and civil rights. This situation is exacerbated by ICE's aggressive actions in communities, raising concerns about the abuse of power.

Cindy Cohn, EFF's Executive Director, likened this data consolidation to past government surveillance programs that were widely criticized. EFF has taken legal action against government data collection practices but believes that public awareness and congressional intervention are crucial to protect individual privacy and security.

The text is a brief notice indicating that the browser is being checked, and it will take just a few seconds to complete the process.

Summary:

The author attempted to set up an ATProto account for Bluesky using did:web but faced several challenges.

1. Setup Process: They installed PDS software on their server, created a did:web by generating a key pair, and uploaded the necessary files to their webserver. However, they encountered issues activating their account, which was initially deactivated.

2. Seeking Help: After seeking assistance from the ATProto community, they deleted the account and started over, only to find their did:web was blacklisted after deletion, which is referred to as being “burned.” This prevented them from interacting with others on Bluesky.

3. Documentation Issues: The author criticized the lack of clear documentation for setting up did:web and highlighted that the process is not user-friendly, especially for new users.

4. Centralization Concerns: They expressed frustration that a centralized system can completely block users from interacting with the platform, contrasting it with other decentralized platforms like Mastodon, which allow for more manageable connections.

The author concluded that despite the potential for decentralization, Bluesky and ATProto still exhibit centralized control, which undermines their claims of being decentralized. They wish for a future where community-driven projects thrive over corporate-backed platforms.

In this article, Modestas Valauskas shares his experience building a faster lexer for Dart code, which processes files twice as quickly as the official scanner. However, he discovered that the real performance issue was related to input/output (I/O) operations, not the lexer itself.

Key Points:

1. Lexer Performance: The new ARM64 assembly lexer was benchmarked against the official Dart scanner using 104,000 Dart files. It achieved a lexing time of 2,807 ms compared to 6,087 ms for the official version, marking it 2.17 times faster. However, the total speedup was only 1.22 times due to I/O overhead.

2. I/O Bottleneck: Despite using a fast NVMe SSD, the I/O operations were slow because of the high number of system calls (over 300,000) required to open, read, and close files. This overhead significantly delayed the reading process, taking 14.5 seconds compared to only a few seconds for lexing.

3. Archiving Solution: To reduce the number of syscalls, Valauskas experimented with packaging the files into tar.gz archives, reducing 104,000 files to just 1,351 archives. This change improved I/O time from 14.5 seconds to just 339 milliseconds, resulting in a total speedup of 2.27 times, even after accounting for decompression time.

4. Broader Implications: The findings suggest that modern storage systems can handle large files quickly, but performance suffers when dealing with many small files due to syscall overhead. This insight applies to various systems, including build systems, log processing, and backups.

5. Future Optimizations: Valauskas plans to further optimize the process by exploring faster decompression methods and potentially using different archive formats that allow random file access without significant overhead.

6. Conclusion: The experience highlights the importance of measuring performance accurately and understanding where bottlenecks occur before attempting optimizations. Focusing on reducing syscall overhead can lead to significant performance improvements.

Overall, this investigation into lexer performance turned into a valuable lesson on the impact of I/O operations and syscall overhead on software efficiency.

This text describes an interactive map of US navigational aids and lighthouses, showing their locations, colors, characteristics, and Coast Guard remarks. The author, while sick with the flu, struggled to find a comprehensive source for active lighthouses and their characteristics. They discovered the Coast Guard publishes an annual list of these lights. With help from a colleague, they created a web app that displays a map of the lighthouses and visualizes their characteristics. The map is for informational purposes only and not meant for navigation. The author finds it interesting, especially having lived in Seattle and San Francisco.

Google has announced that Android will soon implement a "high-friction" process for sideloading apps. This change is intended to raise user awareness about the risks associated with installing apps from unverified sources. Google describes this as an "Accountability Layer" rather than a restriction on sideloading.

While advanced users will still have the option to install apps without verification, it will involve additional steps to ensure they understand the potential dangers. Current updates in Google Play already include warnings about developer verification and other risks.

The concern among users is whether this new process will genuinely be educational or if it will make sideloading more difficult. Historically, Android has been appreciated for its openness, allowing users to install apps with fewer obstacles. At this point, Google has not indicated any drastic changes, such as requiring a PC for installations, and hopes that the new measures will primarily focus on warning users about risks.

Eshaan is developing an app called Ourguide, which provides on-screen guidance for computer tasks. It helps users by showing them where to click step-by-step, making it easier to follow instructions without switching between apps. There are two modes:

1. Guide Mode: Highlights the next element to click directly on your screen.
2. Ask Mode: A chat feature that captures what’s on your screen, allowing you to ask questions without needing to describe the context.

Ourguide works across all operating systems and isn’t limited to web browsers. Eshaan faced challenges in accurately identifying UI elements but has created a simpler version that responds quickly. Instead of automating clicks, Ourguide provides visual guidance, keeping users in control to avoid mistakes.

Eshaan uses it for tasks like managing AWS settings and has found it useful for various other applications. He invites users to download and test Ourguide and provide feedback on its performance and potential improvements.

A recent study has found that a protein produced by cancer cells may help protect the brain from Alzheimer’s disease in mice. Researchers have long observed that cancer and Alzheimer’s rarely occur together in individuals, leading to speculation that one might protect against the other. This study, published in the journal Cell, reveals that the protein cystatin C, secreted by human tumors, can cross the blood-brain barrier and help break down harmful protein clumps associated with Alzheimer’s.

The study, which took 15 years to complete, involved transplanting different types of human tumors into mouse models of Alzheimer’s. The mice with cancer did not develop the typical brain plaques seen in Alzheimer’s. This discovery could pave the way for new treatments for Alzheimer's disease, although experts caution that it's just one piece of a larger puzzle.
