(Why does Google word privacy settings like you agree even when off?)

A user found confusing language in a recent update for their personal Gmail account. The introduction states that by agreeing, users allow Google Workspace to use their content and activity to personalize their experience. However, it is only later that users are given the option to turn features on or off. This wording suggests that users are consenting to data use even if they don’t enable the features. While documentation clarifies that data is only used when features are activated, the initial sentence seems to imply broad consent. The user questions whether this is a deliberate attempt to mislead or just poor writing that causes confusion.

The author, Robert Kingett, reflects on the impact of AI, particularly large language models (LLMs), on the blind community. Despite the excitement surrounding AI tools like Be My Eyes and ElevenLabs, Kingett expresses skepticism about their effectiveness and accuracy. He acknowledges that while blind users appreciate the information these tools provide—often lacking from sighted individuals—they are still concerned about the potential downsides, including accessibility issues and reliance on technology instead of human support.

Kingett notes that many in the blind community may feel empowered and more independent with AI, as it offers a constant source of assistance without judgment. However, he worries that this shift could lead to a deeper dependence on technology, especially as human efforts to create accessible environments often fall short.

He critiques the hype around AI, comparing it to past technologies that over-promised and under-delivered. Kingett prefers reading personal blogs and smaller websites over mainstream AI content, believing they offer a more stable and genuine perspective. In summary, while recognizing the potential benefits of AI, Kingett urges caution and advocates for continued push for real accessibility measures.

"The staff ate it later" is a caption used in Japanese TV shows when food appears on screen. It indicates that the food was not wasted, as throwing away food is generally frowned upon in Japan.

The caption likely started to prevent viewer complaints about food being mistreated on shows. There is some debate about whether the staff actually eats the food after filming. Some reports and TV personalities affirm that the crew does consume leftover food, while others have expressed skepticism about the truth of the caption.

Critics argue that the caption can be seen as a way for producers to avoid responsibility and that it reflects a growing sensitivity to viewer criticism. Some commentators believe this self-regulation may lead to a decline in the quality of programming. Others suggest that teaching children about food ethics should come from parents rather than TV shows.

Summary: Making a Linux Home Server Sleep and Wake on Demand

The author wanted their Linux home server to automatically sleep when idle and wake up when needed, similar to features in Windows. The challenge was to implement this on Ubuntu, specifically for backups without needing to manually turn on the server.

Key Points:

  1. Setup Requirements:

    • A low-power device like a Raspberry Pi on the same network.
    • A network interface that supports wake-on-LAN (WoL) with unicast packets.
  2. Server Configuration:

    • Enable wake-on-LAN for unicast packets using ethtool.
    • Create a script (auto-sleep.sh) to check for logged-in users and active connections, putting the server to sleep if idle.
    • Set up a cron job to run this script every 10 minutes.
    • Disable IPv6 to ensure proper functioning of ARP, which is necessary for waking the server.
    • Optionally, stop network services like Netatalk before the server sleeps to avoid unwanted wake-ups.
  3. Always-On Device:

    • Implement an ARP Stand-in using a Ruby script to respond to ARP requests for the sleeping server, allowing it to be woken up without needing magic packets.
    • Optionally, use Avahi to advertise network services on behalf of the sleeping server.
  4. Troubleshooting:

    • The server sometimes woke up unexpectedly due to unsolicited network packets. The author identified sources of these packets using a network switch with port mirroring.
    • Resolved issues with unwanted wake-ups by stopping services that were sending packets and configuring the router to prevent unnecessary network traffic.
  5. Final Outcome:

    • The server now successfully sleeps when idle and wakes upon receiving network requests, allowing for seamless backups and efficient energy use.

This guide offers a simplified method for setting up a Linux home server that conserves energy while remaining accessible when needed.

Summary of Simplifying Coverage Polygons

Volker Krause discusses the challenges of simplifying geographic polygons, specifically for applications like public transport and emergency services. High-resolution geometries are unnecessary for these use cases and can lead to inefficiencies in storage and processing.

Key points include:

  • Use Cases: Geographic polygons help define areas for public transport services and emergency alerts. High detail isn’t needed; simpler polygons can suffice.

  • Challenges with Simplification: Generic simplification algorithms can reduce detail but may not maintain the coverage of the original area, posing risks in emergencies. A bounding box is too simplistic; a balance is needed.

  • Douglas-Peucker Algorithm: This common method simplifies polylines by reducing points based on distance thresholds. While effective for smooth shapes, it can fail with complex geometries, leading to self-intersecting polygons.

  • Polygon Offsetting: To ensure a simplified hull, polygons can be enlarged (offset) before applying Douglas-Peucker. This method merges details and produces smoother results while fixing self-intersections.

  • Truncating Numbers: Reducing the number of decimal places in coordinates can decrease file sizes without affecting the geometry's quality.

Krause invites suggestions for better algorithms to enhance the quality of simplified geometries.

The article discusses the resurgence of the concept of "world models" in artificial intelligence (AI). A world model is a simplified representation of the environment that an AI uses to make predictions and decisions, similar to how humans understand the world. Prominent AI researchers argue that these models are crucial for developing intelligent and safe AI systems.

The idea of world models dates back to 1943, when psychologist Kenneth Craik suggested that organisms carry mental models to evaluate options and react effectively. Although early AI systems experimented with world models, they faced challenges in handling complex environments, leading some experts to abandon the concept.

However, the rise of deep learning has revived interest in world models. Instead of relying on fixed rules, modern AI can learn from experience and create internal representations of their environments. Despite this progress, current AI systems often rely on disconnected rules rather than a cohesive world model.

Developing robust world models is a priority for AI labs, as they could improve AI reasoning and reliability. However, the methods for creating these models are still uncertain, with different approaches being explored. Overall, the potential benefits of well-constructed world models in AI are driving ongoing research in this area.

Untangling the myths and mysteries of Dvorak and QWERTY (2023)
(Untangling the myths and mysteries of Dvorak and QWERTY (2023))

Summary of "The Primitive Tortureboard"

In this essay, Marcin Wichary explores the history and myths surrounding the QWERTY and Dvorak keyboard layouts. Originally published as a chapter in the book Shift Happens, the text covers the following key points:

  1. QWERTY's Design Flaws: Many people criticize the QWERTY layout for its seemingly haphazard arrangement of letters, causing inefficient typing. George C. Blickensderfer aimed to create a more efficient keyboard design, which he called the Scientific keyboard, introduced in 1893. However, it failed to gain popularity, overshadowed by QWERTY.

  2. Blickensderfer's Innovations: Blickensderfer invented several interesting typewriters but faced continuous challenges, including financial struggles and competition from larger manufacturers like Remington. His Scientific keyboard, despite its potential, could not overcome the QWERTY dominance.

  3. Myths of QWERTY: Common beliefs that QWERTY was random or designed to slow typists are examined and debunked. The layout evolved deliberately to prevent mechanical jams in early typewriters, and evidence suggests it was more efficient than previously thought.

  4. Dvorak's Proposal: August Dvorak, an educational psychologist, and his colleague William Dealey proposed the Dvorak Simplified Keyboard in the 1930s to make typing easier and faster. Their design claimed to reduce finger movement and increase typing speed, but it struggled to gain acceptance in a market dominated by QWERTY.

  5. Conflicting Studies: Early studies showed promising results for the Dvorak layout, but later experiments, including a government study in the 1950s, cast doubt on its advantages. Controversies arose regarding the validity of these studies, leading to a divide between proponents of QWERTY and Dvorak.

  6. Continued Debate: The discussion continues today, with debates about the effectiveness and comfort of both layouts. New keyboard designs have emerged, but QWERTY remains the dominant layout, largely due to historical momentum rather than performance superiority.

  7. Conclusion: Wichary emphasizes that while Dvorak might be faster and more ergonomic, QWERTY is considered "good enough" for most users. The essay ultimately reflects on the complexities of keyboard design and the reasons behind the enduring prevalence of QWERTY.

The text blends historical narrative with analysis, challenging readers to reconsider the assumptions about the keyboards they use every day.

The article "You're Not Interviewing for the Job. You're Auditioning for the Job Title" by Ibrahim Diallo discusses the disconnect between technical interviews and real-world engineering practices.

Key Points:

  1. Interview vs. Reality: In interviews, candidates are often expected to demonstrate knowledge of complex systems and scalability, even when the actual job requires simpler, more practical solutions.

  2. Complexity in Interviews: Interviewers tend to favor candidates who can discuss elaborate architectures and theoretical scaling solutions, rather than those who focus on efficient, straightforward designs appropriate for the job's actual needs.

  3. Theatrical Formula: Interviews follow a predictable structure where candidates must present grand solutions to problems that might not exist in their potential role.

  4. Hiring Dynamics: Companies often aim to hire for future aspirations rather than current needs, leading to a preference for candidates who can speak to complex concepts, even if they aren’t necessary.

  5. The Cost of Honesty: Providing honest, simple answers can lead to disqualification, while complex responses, even if impractical, may secure job offers.

  6. Navigating the System: Candidates are advised to learn the complexities expected in interviews but advocate for simplicity once hired.

The article concludes that while the interview process is flawed, understanding how to navigate it can help candidates secure positions where they can then push for more sensible engineering practices.

Acorn and the future of (AI?) theorem proving
(Acorn and the future of (AI?) theorem proving)

The text discusses the Acorn theorem prover and contrasts it with traditional mathematical proofs and other theorem proving systems like Lean.

Key Points:

  1. Mathematical Proofs: Standard proofs start with a statement and build a logical sequence of statements to reach a conclusion, relying on previously established truths.

  2. Lean Theorem Prover: Lean uses a programming-like syntax with named theorems, which can make it feel less intuitive and more cumbersome compared to human reasoning. Proofs in Lean require detailed definitions and often treat hypotheses as objects.

  3. Acorn Theorem Prover: Acorn takes a different approach, allowing users to write proofs in a more human-readable format. It focuses on making claims and building proofs through a dialogue-like interaction with the AI. The system can recognize previously proven statements without needing users to remember or name them.

  4. Dialogue Interaction: If the Acorn prover cannot find a proof for a claim, it indicates this and may require further clarification or additional claims from the user. This approach mimics how humans might work together to solve a problem.

  5. Potential for Broader Applications: The author suggests that this type of interactive, implicit dialogue could be valuable in other fields, such as experimental design, where tasks can be broken down into verifiable subtasks.

  6. Future Interaction with AI: The text concludes with a hopeful vision of future AI interactions that are more seamless and natural, enhancing everyday tasks rather than simply serving as advanced tools.

Overall, Acorn presents a more intuitive way to engage with theorem proving, potentially bridging the gap between human reasoning and computational proof verification.

Toronto’s network of pedestrian tunnels
(Toronto’s network of pedestrian tunnels)

Toronto has developed an extensive network of pedestrian tunnels called the Path, spanning over 30 kilometers. This system was created in response to congestion in the downtown area, allowing commuters to move smoothly between offices and metro stations while avoiding busy streets. Initially started by businesses in the early 1900s, the Path now connects many major buildings and is maintained by various owners.

Unlike typical underground passages, the Path is well-designed, clean, and resembles a high-end shopping mall, serving as a popular commuting route for hundreds of thousands of people daily. Despite urbanists' concerns that such tunnels might reduce street life, the Path complements the city’s transportation system by relieving congestion and facilitating movement for pedestrians and vehicles alike.

The Path's unique success stems from its economic model, where landowners invest in the infrastructure because it directly benefits them, unlike traditional transport systems that require unified planning. Similar systems exist in other cities like Montreal, but pedestrian metros are still rare. Exploring why they aren't more common could provide insights into improving urban transport.

Triangle Grids (2022)
(Triangle Grids (2022))

Summary of Triangle Grids

Overview: Triangle grids are a type of grid used in tactical turn-based games, similar to the more common square and hex grids. They offer unique advantages in gameplay, movement, and visual representation.

Grid Types:

  • Square Grids: Easy for structured environments (towns, dungeons), but limited in flexibility.
  • Hex Grids: Better for natural landscapes, allowing for smoother shapes.
  • Triangle Grids: Combine the benefits of both square and hex grids, facilitating straight lines and curved movements. However, they cannot easily represent rectangular buildings.

Visual and Tactical Benefits:

  • Triangle grids enable effective line formations for units and allow for 6 directional movements, compared to 4 for square grids and 6 for hex grids.
  • They provide 12 directional options if diagonal movements are allowed, giving players more tactical choices.

Movement and Distance:

  • Hex grids are great for estimating distances, while square grids are straightforward but less flexible.
  • Triangle grids can be tricky without diagonals, as moving between opposing triangles takes three steps. Allowing diagonal moves can enhance realism and convenience.

Heightmap Terrains: Triangle grids can improve terrain representation in games, potentially leading to innovative designs.

Coordinate Systems: Triangle grids can be represented using coordinates similar to square grids, with additional calculations for conversions between grid and world coordinates.

Distance Calculations: Two methods to calculate distances on triangle grids:

  1. Simple Tile Distance: Based on Manhattan distance with three components.
  2. Diagonal Distance: Adjusts calculations to account for diagonal moves, either with shortcuts or by treating diagonals as distance one.

Conclusion: Triangle grids have not been widely adopted in released games, but they present interesting possibilities for tactical gameplay. They allow for unique design elements and might inspire new game mechanics in the future.

Indices, not Pointers
(Indices, not Pointers)

Summary of "Indices, not Pointers"

The text discusses a technique for improving the performance of data structures in the Zig programming language by using indices instead of pointers. This method, inspired by Andrew Kelley, Zig’s creator, offers several key benefits:

  1. Memory Efficiency: Using indices means nodes are stored in a dynamic array, which takes up less space compared to using pointers (4 bytes for an index versus 8 bytes for a pointer on a 64-bit system).

  2. Faster Access: Nodes stored contiguously in memory improve access times because they fit better in the CPU cache.

  3. Reduced Allocation Overhead: Instead of allocating memory for each node individually, which can be slow, using an array allows for quicker memory allocation as new nodes can be added to the next available spot without frequent memory requests.

  4. Instantaneous Freeing: Freeing all nodes at once becomes faster since it only requires a single memory deallocation rather than traversing the entire structure.

  5. Downside - Individual Node Freeing: The main drawback is that removing a single node from the array is slow, as it requires shifting elements. To address this, a "freelist" can be used to keep track of free slots when freeing specific nodes.

The text includes a code example in Zig demonstrating how to implement this technique using an array list to manage tree nodes, highlighting the structure of the node and the methods for creating nodes and setting child relationships.

Koyeb has made significant advancements in optimizing application efficiency and reducing cold start times to around 200 milliseconds for CPU workloads with their new feature, Light Sleep. This involves rethinking app deployment and utilizing eBPF technology to manage virtual machines (VMs) more effectively.

Initially, Koyeb used Firecracker, a lightweight virtual machine monitor, but switched to Cloud Hypervisor for broader hardware support, particularly for GPU instances. They incorporated Kata Containers to create a more flexible system that allows for easy transitions between different virtualization backends.

During the transition, Koyeb encountered challenges with snapshot restoration and network management. They had to move away from using virtio-fs due to bugs and found that restoring network connections after a VM snapshot was more complex than anticipated. To address these issues, they developed custom solutions, including kernel-level idle detection with eBPF to identify when instances could be paused.

To keep services responsive, Koyeb implemented mechanisms to ignore health check traffic when determining if an instance is idle. When no real traffic is detected, the system pauses the VM and saves its state. They also created a workaround to prevent orchestration failures when paused containers do not respond to health checks by proxying those checks to a dummy server.

As a result, Koyeb can now wake services quickly when real traffic arrives. However, they are planning to extend their snapshotting capabilities to GPU-based services, which presents new challenges.

Overall, Koyeb's improvements allow applications to scale to zero, conserve resources, and wake up instantly without disrupting user experience.

Eric Markowitz shares his profound experience before and after a high-risk brain surgery. On the eve of the operation, he felt a deep sense of consciousness and connection to life, appreciating the beauty and fragility of existence. Despite the fear of potential death, he was enveloped by a powerful awareness of the present moment and the love for his family.

After surviving the surgery, which revealed a benign condition, Markowitz underwent a challenging recovery but felt a renewed sense of euphoria and clarity about what it means to live. He realized that consciousness goes beyond mere thoughts; it is intertwined with care and love. This experience taught him that living is an active choice, requiring attention, compassion, and the acknowledgment of life’s interconnectedness.

Reusing Computation in Text-to-Image Diffusion for Efficient Image Generation
(Reusing Computation in Text-to-Image Diffusion for Efficient Image Generation)

Text-to-image diffusion models can create high-quality images but require a lot of computing power. Instead of focusing on improving efficiency for each image generation, we propose a new method that reduces redundancy in similar prompts. Our approach uses the way diffusion models work, where initial steps can identify common features in related prompts. We cluster prompts based on their meanings and share calculations during the early steps of the diffusion process. Tests show that our method decreases computing costs and improves image quality for models that use image embeddings. By utilizing UnClip's text-to-image capabilities, we optimize how diffusion steps are allocated for better efficiency. This method easily fits into existing systems, works well with large sets of prompts, and lowers both environmental and financial costs for large-scale image generation.

Next.js is infuriating
(Next.js is infuriating)

The author has finally written a blog post after struggling to find motivation. They describe a project involving setting up logging for a Next.js service, which has poor default logging capabilities. The journey begins with configuring middleware for logging and selecting the pino logging library.

The author encounters limitations with Next.js middleware, such as the inability to pass multiple parameters or chain middlewares effectively. They explore using AsyncLocalStorage to manage logging context but face challenges when trying to log from different parts of the application, revealing that rendering occurs in a different async context than middleware.

To work around these limitations, they create separate logging functions and headers to pass data between middleware and pages. Ultimately, they express frustration with Next.js's design choices, particularly when comparing it to SvelteKit, which offers a more flexible middleware system.

The author criticizes Vercel's (Next.js's creator) lack of responsiveness on their GitHub issue tracker, citing a poor support experience. They conclude by expressing a desire to move away from Next.js due to ongoing frustrations and bugs, pondering whether future projects might use a different framework.

OpenAI says it's scanning users' conversations and reporting content to police
(OpenAI says it's scanning users' conversations and reporting content to police)

OpenAI has recently announced that it is monitoring user conversations in ChatGPT for harmful content and may report certain cases to the police. This follows increasing concerns about AI chatbots leading to mental health crises, including self-harm and violence. OpenAI admitted to its failures in handling these issues and stated that when users are detected planning to harm others, their conversations will be reviewed by a trained team, and serious threats may be referred to law enforcement.

However, OpenAI clarified it will not report self-harm cases to the police to respect user privacy. The guidelines for what constitutes harmful content are vague, leaving uncertainty about which conversations might be flagged. Critics point out this monitoring contradicts OpenAI's pro-privacy stance, especially amidst a lawsuit regarding user data.

The company faces criticism for poor control over its technology and the resulting mental health crises among users, leading to a conflicted approach between moderation and privacy promises.
