The author shares their experience with using AI tools like Claude-code for coding and how it led to feelings of depression and lethargy. They initially found the ease of generating code with AI tempting but realized it hindered their understanding of coding problems and made them less engaged in their work. Writing code by hand helped them think critically and internalize the context of the problems they were solving.

The author notes that while vibe coding (using AI to generate code) can provide quick results, it can also lead to a passive mindset, making it harder to think deeply and verify the correctness of the code. They emphasize that tools should enhance thinking, not impede it.

To find a balance, the author uses AI in a controlled way, providing necessary context and making deliberate changes to code. This approach keeps them engaged and happy in their work, highlighting that prioritizing happiness is essential, even if it means sacrificing some productivity.

The author discusses their experiences with AI in engineering, highlighting both the increased productivity and the resulting burnout. They shipped more code than ever but felt more exhausted, which they attribute to the nature of AI work.

Key points include:

1. Increased Workload: AI makes tasks faster, leading to more tasks being taken on, resulting in cognitive overload and exhaustion.

2. Shift from Creation to Review: Engineers are spending more time evaluating AI-generated output rather than creating, which is draining.

3. Nondeterminism of AI: AI output can vary unpredictably, causing stress and requiring constant vigilance from engineers who prefer predictable, deterministic results.

4. Hype and Tool Fatigue: The rapid evolution of AI tools leads to anxiety over keeping up, resulting in wasted time on new systems that may not provide significant benefits.

5. Perfectionism vs. AI Output: Engineers' tendency toward perfectionism clashes with the imperfect nature of AI-generated work, leading to frustration.

6. Cognitive Atrophy: Relying too much on AI can degrade critical thinking skills, as engineers stop exercising their problem-solving abilities.

7. Comparison Trap: Social media can amplify feelings of inadequacy as people showcase their AI successes, ignoring the struggles behind the scenes.

To cope, the author suggests time-boxing AI sessions, separating thinking time from AI use, accepting that AI output doesn't need to be perfect, and focusing on sustainable practices.

They conclude that the key skill in the AI era is knowing when to stop and recognizing the need for balance in using AI to avoid burnout. The author emphasizes the importance of protecting mental resources and finding a sustainable approach to work with AI.

The author, Theo Downes-Le Guin, reflects on curating an exhibition about his mother, the renowned writer Ursula K. Le Guin, who passed away in 2018. He shares that he would not have proposed such a show while she was alive, as she resisted being categorized or simplified. The exhibition, titled "A Larger Reality" at Oregon Contemporary, features her first typewriter, allowing visitors to engage with her legacy by typing on it. This interaction evokes nostalgia and connects people to her work.

Theo discusses the emotional complexities of curating the show, including feelings of grief and joy as he revisits his mother’s letters and writings. He acknowledges the challenge of presenting her life without reducing her multifaceted identity. Ursula often revised her work and herself, and Theo aims to reflect that dynamic nature rather than create a fixed portrayal.

He critiques traditional narratives in exhibitions, suggesting that they can oversimplify complex subjects. Inspired by Ursula’s ideas, he believes exhibitions should serve as "carrier bags" that hold a variety of perspectives and allow for exploration rather than conforming to linear storytelling. The result is an engaging exhibition that embraces the complexities of his mother's life and work.

Summary:

In the 17th century, cancer treatment was mostly focused on comfort care, but doctors experimented with various methods, including invasive surgery. One notable case was that of Samuel Smith, a surgeon who, after performing a mastectomy, tasted the cancerous tissue. This led to severe health issues and ultimately his death, as he believed the taste was the cause of his decline.

Medical writers later discussed Smith's case, linking it to the idea that cancer was similar to poison. Many in the early modern period thought that emotional responses to strong sensory experiences could make people ill. For instance, during plagues, seeing or smelling disease could lead to illness. Some even believed that looking at cancer patients could cause cancer, leading to the isolation of these patients.

As medical understanding evolved, later surgeons like William Beckett and Samuel Young explored Smith's death from different angles, suggesting that the foul taste or smell might have contributed to his suffering. By the 19th century, beliefs about the senses causing illness began to fade, and medical advancements like radiotherapy and chemotherapy improved the understanding and treatment of cancer.

A computer systems engineering student in Mexico created CineGraphs, a tool for filmmakers to explore their ideas more effectively. Frustrated by generic outputs from existing AI writing tools, he designed CineGraphs to generate branching narrative paths from rough concepts, visualized as graphs. This allows users to develop structured screenplays that can be exported to professional software.

To improve narrative quality, he curated a list of 100 diverse films with unique storytelling styles, focusing on their structural elements rather than just summaries. He built a complex Python pipeline to analyze these films, extracting key narrative components and relationships.

After creating a dataset of 10,000 narrative pairs, he fine-tuned an AI model to generate branching stories and format them for screenwriting. The graph structure lets writers explore various narrative paths before finalizing their choices, aligning with how they think during the development process.

The US Supreme Court will hear a case about whether the 1988 Video Privacy Protection Act (VPPA) applies to online users who sign up for newsletters from websites using Meta’s tracking technology. The lawsuit claims Paramount Global shared users' identities and video information with Facebook without consent. The main question is whether someone who subscribes to a free newsletter is considered a "consumer" protected by the VPPA, which was created to prevent the disclosure of video rental histories.

A lower court sided with Paramount, stating that since the plaintiff only subscribed to a free newsletter and not to paid video services, he does not qualify as a consumer under the VPPA. Paramount argues that the VPPA was made for video rental services and doesn’t cover modern internet advertising.

This case highlights ongoing concerns about data privacy, especially as other courts have found similar data-sharing practices may not violate privacy laws.

Wood Gas Vehicles: Firewood in the Fuel Tank Summary

During World War II, many vehicles in Europe were converted to run on wood gas, a fuel made from firewood. This technology, while not elegant, proved to be an efficient and eco-friendly alternative to gasoline. The process of wood gasification converts organic material into a combustible gas using high heat, which can then be used to power vehicles with minimal modifications.

The popularity of wood gas vehicles peaked during the war due to fuel shortages, with around 500,000 in Germany alone by war's end. After the war, as gasoline became available again, interest in wood gas vehicles declined sharply.

Recently, rising fuel prices and environmental concerns have revived interest in this old technology. Amateur engineers, especially in Scandinavia, have started to convert modern cars into wood gas vehicles, or "woodmobiles." A Swedish research program in the 1950s aimed to prepare for future oil shortages by developing better wood gas technology.

Wood gas cars can achieve speeds comparable to electric vehicles, with ranges depending on the amount of wood used. However, they require time to heat up and are less user-friendly than conventional cars. Additionally, the use of wood gas can produce harmful emissions, necessitating proper filtration systems.

While wood gas vehicles are not as convenient as those powered by gasoline, they offer a renewable fuel option. However, widespread adoption could lead to deforestation, raising sustainability concerns. Overall, wood gas vehicles represent a potential alternative fuel solution, but their practical applications are limited compared to modern options.

4. Game Cracking: The text describes how individuals modified game files to bypass copy protection, allowing them to play games without the original disks or manuals. Various tools and utilities were developed to facilitate this process and manage copy-protected disks.

5. Disk Copying Utilities: Several software tools emerged for copying disks, including those that could bypass copy protection techniques. Some utilities, like Copy II Plus and Copy II PC, became controversial for their ability to duplicate protected disks.

Overall, the document highlights the evolution of software protection and the methods used by both companies and users to protect or bypass those protections in the computing world, particularly during the DOS era.

Coding agents are improving, and the main question is which one to use. However, their performance can vary greatly depending on the programming language, the type of task, and timing. Instead of relying on a single agent, a better approach is to use multiple agents and select the best solution from their outputs. This method is called "best-of-N," where several agents work in parallel, and a human reviewer chooses the best result.

In our process, we test multiple agents on real coding tasks and track which agent produces the best code. We have analyzed results from 211 tasks across 18 agents, focusing on tasks like feature development and bug fixes.

The performance of coding agents shows that while there are top performers, the differences between them can be small and uncertain. Using a cohort of agents leads to significantly better outcomes. For example, using the top three agents increases the chances of finding the best solution from 24% (with one agent) to 51%. Adding more agents improves the chances further, but beyond seven agents, the benefit decreases.

In summary, coding agents can be grouped by performance, and while it's hard to predict the best one for a specific task, using a few top agents usually yields better results. It’s often worth using multiple agents to ensure better code quality and reduce the need for extensive revisions later.

Geo joins, which involve joining tables based on spatial relationships (like intersections), can become slow and inefficient as data size increases. Typically, modern databases optimize joins using hash keys, but spatial joins don't provide clear keys, leading to increased complexity and longer processing times.

The solution discussed in this text is the use of H3, a system that divides the Earth into hexagonal cells, allowing for efficient spatial operations. H3 provides the ability to represent geographic data as sets of cell IDs, enabling a shift from complicated spatial checks to simpler equi-joins based on cell overlaps.

The process to optimize a geo join involves creating H3 coverage for each table, performing a quick join on these cell IDs, and then checking the actual spatial relationship only on the reduced set of candidates. This method significantly speeds up the operation, reducing the number of expensive spatial checks needed.

Key points include:

• H3 allows for efficient spatial indexing and querying.
• The approach reduces the workload from a complex spatial predicate to a fast integer join, followed by a cleanup step for accuracy.
• The implementation is flexible, working with various database structures without needing extra storage or maintenance.

In tests, using H3 indexing has shown dramatic improvements in query speed, achieving up to a 400 times speed increase compared to traditional methods. The choice of H3 resolution impacts performance, balancing the size of the cell with the processing time for indexing and joins. Overall, this strategy enhances the efficiency of geospatial queries in databases.

The article discusses the potential collapse of the Atlantic Meridional Overturning Circulation (AMOC), a crucial ocean current that helps keep Europe and North America warm. Recent studies indicate that the AMOC is weakening, with the 2021 study showing it at its weakest in over 1,000 years. Warming in the deep Atlantic and changes in ocean salinity are signs of this decline.

While some models suggest a collapse is unlikely before 2100, predictions for the years 2300 and 2500 indicate a high risk if carbon emissions continue to rise. A tipping point may be reached in the next 10 to 20 years. Some studies, however, present a more optimistic view, claiming that the AMOC may not have weakened as previously thought and could decline less than earlier projections suggested.

The potential impacts of an AMOC collapse include severe temperature drops in Europe, rising sea levels, and significant climate changes globally. Iceland has already recognized this as a security risk and is taking steps to prepare for possible future impacts. Overall, while the situation is serious, there are other urgent climate issues that also need attention.

The FDA plans to take action against companies selling non-FDA-approved GLP-1 drugs, which are being marketed as alternatives to approved medications. This is to protect consumers from drugs that the FDA cannot confirm are safe or effective. The FDA will also address misleading advertising claims made by these companies, such as stating that compounded drugs are the same as FDA-approved ones or that they are clinically proven. Companies that do not comply with these regulations may face legal action. The FDA emphasizes its commitment to ensuring public health and safety regarding drug quality.

Summary of "Dark Alley Mathematics"

In a tense situation, a person is threatened in a dark alley and must solve a mathematical problem to avoid harm. The problem involves calculating the probability that the circumcircle formed by three randomly chosen points inside a unit circle is completely contained within that circle.

The individual approaches the problem by converting the coordinates of the points into parameters related to the circumcircle's center and radius. They calculate the Jacobian determinant of the transformation, which requires some complex matrix manipulations and understanding of properties of determinants.

After simplifying, they find that the Jacobian determinant involves the sine of the differences between the angles of the points. Next, they set up the integral for the probability, which involves both an angular part and a geometric part. They compute these integrals, leveraging trigonometric identities and symmetry, ultimately arriving at an expression for the probability.

After further calculations involving integration, they determine the final probability to be 25. The hoodlum, satisfied with the answer, allows the person to leave, who then reflects on the stressful experience and vows to avoid dark alleys in the future.

Summary of "What Is Ruliology?"

Ruliology is a new scientific field focused on understanding how systems behave when they follow simple rules. The term was created by Stephen Wolfram, who has been exploring this area for over 40 years. In ruliology, researchers set up abstract rules and observe their outcomes, which provides insights into the behavior of simple programs within the vast computational universe.

Unlike computer science, which deals with programs designed for specific tasks, ruliology examines rules that exist independently. It's also distinct from mathematics, as it emphasizes observing rule behavior rather than proving frameworks. Ruliology is an experimental science, often beginning with specific cases and generalizing from there, while grappling with concepts like computational irreducibility, which means some outcomes may require immense computational effort to determine.

Ruliology helps in studying complexity, providing foundational knowledge for creating models and understanding systems. It combines elements of natural science with a focus on generating new ideas about what can emerge from simple rules. Ruliology benefits from tools like the Wolfram Language, which facilitates exploration and visualization of rule behaviors.

In summary, ruliology is about exploring the consequences of simple rules, uncovering unexpected behaviors, and building a comprehensive understanding of the computational universe. It holds potential for future research and technological advancements.

Last spring, I wondered how difficult it would be to create my own version of Google Workspace, especially considering the dominance of big tech companies in the USA. Surprisingly, after two months of part-time development (with help from Mark), I built a working prototype called Eigen, which means "own" in Dutch/German. You can try it at eigen.is.

Eigen includes:

• Mail: A simple webmail client for sending and receiving messages.
• Drive: File storage and sharing with folder creation.
• Docs: Collaborative text editing with real-time editing capabilities.
• Contacts: Basic contact management.
• Stickies: Kanban boards for task management.

The system is built using modern technologies, focusing on simplicity by giving each user their own data directory and using SQLite databases to store information. This design isolates user data, making backups easier and scaling simpler. However, there are challenges, such as document sharing and real-time collaboration.

Although I have made significant progress, this is just a small part of what needs to be developed (less than 5%). Missing features include end-to-end encryption, calendar functionality, and compatibility with standard protocols. I also need to explore the scalability of the current architecture and how to make Eigen extensible for users.

Next steps involve gathering feedback, refining the project, and open-sourcing the code for community input. My goal is to create a simple and secure workspace where users own their data. If you're interested in contributing or trying out Eigen, please visit eigen.is or contact me at [email protected].

The article "The Silent Death of Good Code" by Amit Prasad discusses the author's passion for writing "Good Code," which he defines as code that is easy to read, maintain, and serves a clear purpose. Despite his dedication to creating quality software, Prasad notes that Good Code is becoming increasingly rare. He explains that, as a Software Engineer, his role focuses on solving real problems rather than just writing good code.

Prasad shares a recent experience where a colleague rewrote a complex system from C to Rust. The initial rewrite lacked clarity and maintainability, but after the colleague invested time to understand the original code, the new version became much better—flowing naturally and being easier to work with. This experience reignited Prasad's excitement for coding, which he feels has diminished over time.

He reflects on how modern coding often relies on automated agents that produce acceptable code, but not Good Code. He expresses concern that the passion for creating high-quality code may be fading as the field of Software Engineering evolves, mourning the loss of what he sees as an important aspect of coding culture.

Summary of "PC Floppy Copy Protection: Vault Prolok"

This blog post discusses Vault Prolok, a floppy disk copy protection method for PC software, part of a series on copy protection techniques. Vault Corporation was founded in 1979, and its first product, Prolok, was introduced in 1983. Prolok gained popularity for its unique approach to copy protection, which involved creating intentional damage on disk surfaces—referred to as a "fingerprint"—instead of using unconventional disk formats.

Software publishers could buy pre-damaged diskettes and use a utility to encrypt their programs onto these disks. Prolok was marketed as a strong defense against piracy, with significant customers like Ashton-Tate, but it ultimately failed to eliminate software piracy.

Prolok's technology relied on a security check that allowed access to data only if the disk's fingerprint was present. If it wasn't, the program would prevent access to the data or could even erase it. Vault also produced variants like Hard Disk Prolok and Filelok, which offered different protections for software and data.

Despite its innovative features, Prolok was eventually cracked by software like Quaid Software’s RAMKEY, leading to a legal battle that confirmed user rights to make backup copies of software. This lawsuit negatively impacted Vault's reputation, especially after they hinted at destructive features in future products.

The post concludes by discussing Vault's decline and efforts to emulate Prolok in modern computing environments, emphasizing its historical significance in the evolution of software copy protection.

4. Contribution Quality: The author believes that if coding becomes easier through AI, distinguishing between good and bad contributions may become harder, reducing the value of external contributions.

5. Future of Contributions: The author suggests limiting external contributions until better tools are available to manage them effectively, focusing instead on contributions that add value through feedback and discussion rather than code.

Overall, the author advocates for a more cautious approach to accepting code from external contributors while acknowledging the changing landscape of software development due to AI advancements.

The text discusses the author's journey in effectively integrating AI tools into their workflow, detailing six key steps:

1. Drop the Chatbot: The author suggests avoiding chatbots for coding tasks due to their limited efficiency and the need for constant corrections. They recommend using agents, which are more capable AI tools that can read files, execute programs, and make HTTP requests.

2. Reproduce Your Own Work: Initially unimpressed with AI, the author forced themselves to replicate their manual coding efforts using agents. This process, although time-consuming, helped them understand the tools better and ultimately led to improvements in their workflow.

3. End-of-Day Agents: The author started using agents for tasks at the end of the day to make progress while not actively working. They found agents useful for deep research, exploring vague ideas, and triaging issues.

4. Outsource the Slam Dunks: By identifying tasks that agents could handle well, the author began delegating these tasks to agents while they focused on more complex work. They learned to turn off notifications to maintain efficiency.

5. Engineer the Harness: The author emphasizes improving agent performance by addressing their mistakes and ensuring they produce quality results. This involves creating better prompts and tools for agents.

6. Always Have an Agent Running: The goal is to have an agent consistently working in the background. The author aims to improve their ability to delegate tasks to agents without compromising on quality.

In summary, the author shares their methodical approach to using AI tools, highlighting the importance of understanding both the strengths and limitations of these tools to enhance productivity. They are open to adapting their methods as technology evolves and respect individual choices regarding AI use.

The text discusses a method for generating outputs in language models (LLMs) using a process inspired by associative and applicative programming languages, rather than the typical top-down approach. The author suggests using a "sideways passing join" technique to manage data more efficiently, allowing for local modifications in programs.

The author conducted experiments to benchmark how well different models (Opus and Haiku) perform when constructing parity trees (structures that assess whether the sum of child nodes is even or odd). The experiment compared the effectiveness of prefix and postfix notation for generating answers.

Results showed that:

• Thinking improves performance.
• Opus outperforms Haiku.
• Postfix notation is more effective than prefix.

The findings indicate that the order of operations matters and that the combination of thinking and the right notation can significantly enhance the model's accuracy.

Last week, I tried to point my domain to a new server but the old site still showed up. After some troubleshooting, I learned about DNS propagation and how DNS works.

Key Points:

1. What is DNS?

   • DNS (Domain Name System) translates website names (like example.com) into IP addresses (like 93.184.216.34) so that browsers can connect to websites without needing to memorize IPs.

2. DNS Structure:

   • Root Servers: The starting point of DNS lookups, directing requests to TLD (Top Level Domain) servers. There are 13 root server clusters worldwide.
   • TLD Servers: These servers manage domains under their extension (like .com, .org). They know where to find specific domains.
   • Domain: The actual name you buy, like example.com, from registrars (e.g., Namecheap, GoDaddy).
   • Subdomain: Any part before the main domain (like api.example.com), which you can create for free if you own the domain.

3. DNS Records:

   • These are settings that connect your domain to other addresses.
   • A Record: Links a domain to an IPv4 address (e.g., example.com to 93.184.216.34).
   • AAAA Record: Similar to A Record but for IPv6 addresses.
   • CNAME Record: Points to another domain instead of an IP (e.g., www.example.com to example.com).

Understanding these concepts helped me troubleshoot my domain issue effectively.

The author, Jason Fried, discusses his experience renting a modern, high-tech home in Southern California for his parents. Although the house features the latest technology, such as touch screens and programmable buttons, he finds it frustrating. Traditional light switches have been replaced with complicated panels that require a tutorial to operate, making it difficult for guests to use them, especially at night. Fried argues that homes should not require a tech guide just to turn on the lights, highlighting the drawbacks of overly complicated smart home systems.

The author is concerned about memory loss from bike-related concussions and has created a solution to securely store important data. They used a method called Shamir Secret Sharing combined with age-encryption, and packaged it for easy use in web browsers. This system allows friends and family to help regain access to important information if something happens to the author, requiring agreement from 5 out of 7 friends to unlock the vault. A demo of the system is available on their website and works entirely in the browser.
