The author wanted to verify their identity on LinkedIn to get a blue checkmark, which signifies authenticity amidst fake accounts. However, they discovered that the verification process actually involves a third-party company called Persona, which collects extensive personal data, including:

• Full name, passport information, and national ID number
• Biometric data from a selfie and passport scan
• Contact information and device details
• Behavioral data, like hesitation and copy-paste tracking

Persona also cross-references this data with various third-party databases and uses the images for AI training. The author realized that their data is accessible to LinkedIn, Persona's partners, and potentially law enforcement due to US laws like the CLOUD Act, which allows the US government to access data stored abroad.

Despite Persona's claim of compliance with EU data privacy laws, the author raises concerns about the effectiveness of these protections, especially since US surveillance laws could compromise European data security. Additionally, Persona limits its liability for data breaches to just $50 and requires arbitration for disputes, complicating legal recourse for individuals.

The author suggests that anyone who has verified their identity should request data deletion and be cautious about future verifications, as the risks of sharing sensitive biometric information may outweigh the benefits of a simple verification badge.

Summary:

The Dead Language Society explores the complex history of the English language through a fictional blog post about a visit to the town of Wulfleet. The post starts in modern English and gradually shifts back through time, showcasing how the language has evolved over a thousand years.

As the blogger writes, the language becomes increasingly unfamiliar, with changes in spelling, grammar, and vocabulary. By the end of the post, it resembles Old English, making it hard to understand.

Key points include:

• Written English has remained stable for the last 300 years but has changed significantly over the past centuries.
• Earlier forms of English had different spelling conventions and used letters that are no longer in use today.
• The evolution from informal blog-style writing to more formal historical styles reflects broader changes in language and society.
• The narrative also suggests a story of a mysterious "Master" in Wulfleet, adding an intriguing layer to the exploration of language change.

The piece invites readers to notice where they struggle with understanding and to appreciate the journey of the English language through time.

The aim is to create a pixel-perfect and mod-friendly version of Wolfenstein 3D using the Rust programming language.

• Volume 2: Book of Notes - Contains writings from the Nekochan forums.
• Volume 3: Book of Illustrations - Features a photo gallery of Nekochan images.

In February 2026, a diving instructor and platform engineer shared his experience of discovering a serious security vulnerability in the member portal of a diving insurer while on a trip to Cocos Island, Costa Rica. The flaw allowed anyone to access personal information of users, including minors, by simply guessing a numeric user ID and using a default password that was never changed.

He responsibly disclosed the issue to the organization and the relevant authorities, allowing them a 30-day period to fix it before going public. Although the organization did address the vulnerability, they responded with legal threats instead of appreciation. They claimed he compromised their reputation by notifying authorities and attempted to silence him through a confidentiality agreement.

The instructor refused to sign the NDA, asserting the importance of transparency in reporting vulnerabilities. He highlighted that under GDPR regulations, the organization was responsible for notifying affected users about the data breach, a step they failed to take.

This incident reflects a broader issue in the security community where researchers often face legal intimidation rather than support when reporting vulnerabilities. The instructor emphasized the need for organizations to establish clear policies for vulnerability disclosures and to acknowledge the role of researchers in improving security, rather than viewing them as threats.

Summary of sandbox-exec: A macOS Command-Line Sandboxing Tool

Overview: sandbox-exec is a command-line tool in macOS that allows users to run applications in a secure, isolated environment known as a sandbox. This prevents applications from accessing system resources unless explicitly permitted, enhancing security.

Key Benefits of Sandboxing:

• Protection from Malicious Code: Limits access to sensitive files when testing unknown applications.
• Damage Limitation: Reduces the impact of vulnerabilities in trusted applications.
• Privacy Control: Denies access to personal directories.
• Testing Environment: Developers can test applications with restricted permissions.
• Resource Management: Controls how much system resources an application can use.

Using sandbox-exec: To use sandbox-exec, you must create a sandbox profile that defines the rules for what the application can and cannot do. The basic command format is:

sandbox-exec -f profile.sb command_to_run

where profile.sb outlines the sandbox rules.

Types of Sandbox Profiles:

1. Deny by Default: Starts by denying all access and allows only specified operations (most secure).
2. Allow by Default: Allows all access except for specified operations (easier but less secure).

Examples:

• To run a sandboxed terminal that cannot access the network:

sandbox-exec -f terminal-sandbox.sb zsh

• To use a pre-built profile included with macOS:

sandbox-exec -f /System/Library/Sandbox/Profiles/weatherd.sb command

Debugging: If an application fails in the sandbox, you can use the Console app or Terminal logs to identify which operations were denied.

Limitations:

• Apple discourages using sandbox-exec in favor of App Sandbox for developers.
• Complex applications may require extensive testing for effective sandboxing.
• There is no graphical interface for sandbox-exec, making it less user-friendly.

Conclusion: sandbox-exec is a powerful tool for users who want granular control over application security in macOS. It allows for the creation of tailored security profiles, making it valuable for security-conscious users and developers working with untrusted code. For more information, users are encouraged to explore Apple's official documentation on sandboxing.

AI uBlock Origin Blacklist Overview

This is a personal blacklist for uBlock Origin designed to block websites that generate low-quality AI content, often filled with ads and referral links. Users can subscribe to this list automatically if they have uBlock Origin installed, or manually import it from a provided URL.

Purpose of the List The creator of the list aims to improve online search results by blocking sites that provide unhelpful AI-generated content. They believe that when seeking information, users prefer insights from real people rather than AI, which can produce unreliable and potentially harmful information.

Adding Websites Users can suggest websites to be added to the list by reporting them. The creator manually reviews and adds entries based on specific patterns that identify AI content farms, like unnecessary introductions, lack of credible sources, and excessive referral links.

Identifying AI Content Signs of AI-generated websites include:

• Overly complex introductions
• Generic titles like "Ultimate Guide"
• Few external links or references
• Many referral links
• Poor formatting and excessive length
• Vague or irrelevant content
• Rapid publication of numerous articles

Google Dorks The list includes search phrases (known as Google Dorks) to help users find AI-generated content more easily.

FAQs Common questions include concerns about being listed, use of AI for grammar correction, and requests to remove previously listed domains.

Related Projects The author mentions similar projects that aim to block AI-generated content, but their focus is specifically on low-quality content farms.

The Canon Cat uses a programming language called Forth, which allows users to write scripts for the device.

On February 20, 2026, a recommendation was made to turn off Dependabot, a tool that sends security alerts for software dependencies. It was criticized for generating excessive noise and distracting from meaningful work, particularly in the Go programming ecosystem. Instead, it was suggested to use two scheduled GitHub Actions: one running govulncheck, a vulnerability scanning tool, and the other testing code against the latest versions of dependencies.

A case study highlighted how Dependabot generated thousands of irrelevant pull requests related to a minor security fix in a package that most projects did not use. This led to unnecessary alerts, even for projects that did not depend on the affected package.

The article emphasized that better vulnerability scanners could filter out irrelevant alerts and that developers should run tests against the latest dependencies without updating them immediately. This approach reduces risks of exposing projects to malicious code while still catching potential issues early.

Overall, the message was to reduce alert fatigue and focus on more effective security practices by replacing Dependabot with targeted GitHub Actions for vulnerability scanning and testing.

The author reflects on their first visit to Facebook in about eight years and finds the platform has drastically changed. They expected to see posts from friends but instead encountered a feed filled with AI-generated images of young women and irrelevant content, mostly not from people or pages they follow. The author notes that while some content was humorous and engaging, much of it felt like low-quality "engagement bait." They express concern about the prevalence of AI-generated content and the potential impact on users, especially those who may be more vulnerable. Ultimately, the author is disturbed by the changes and decides to leave Facebook again, only considering it for future practical needs.

Summary of Lean4 and Its Impact on AI

Lean4 is an open-source programming language and theorem prover that enhances the reliability and safety of AI systems. Unlike traditional AI models, which can produce unpredictable and incorrect outputs, Lean4 ensures that every theorem or program is rigorously verified, providing a binary confirmation of correctness. This deterministic behavior means that given the same input, Lean4 will always produce the same verified result, which is critical for high-stakes domains like finance and medicine.

Key advantages of Lean4 include:

1. Precision and Reliability: Formal proofs eliminate ambiguity, guaranteeing that each reasoning step is valid.
2. Systematic Verification: Lean4 can verify that solutions meet specified conditions.
3. Transparency and Reproducibility: Anyone can check Lean4 proofs independently, providing a clear audit trail.

Lean4 is increasingly being used to improve the accuracy of large language models (LLMs) by formally verifying their reasoning processes. By using Lean4, AI systems can prevent issues like “hallucinations,” where the AI confidently makes false claims. For instance, Harmonic AI’s system, Aristotle, generates Lean4 proofs for its math solutions, ensuring no hallucinations occur.

Lean4 also has significant implications for software security, enabling the creation of bug-free code through formal verification. This can drastically reduce risks in critical sectors like banking and healthcare. While current AI models struggle to generate fully verified solutions, advancements in AI reasoning are making progress in this area.

The integration of Lean4 into AI is still developing, facing challenges in scalability, model limitations, and the need for user expertise. However, as AI systems increasingly impact our lives, the need for trust and verification is more important than ever. Lean4 represents a promising approach to ensuring that AI behaves safely and correctly, providing a competitive edge in AI development.

The author wants to sync personal Git repositories across devices, such as dotfiles and terminal settings. Initially, they used GitHub but are now seeking alternatives to reduce reliance on cloud services, especially US-based ones. They realized that all they need is a simple way to sync files without extra features.

A Git repository consists of a .git folder that contains the repo's history. You can copy this folder to sync repos, but for regular syncing, using Git’s built-in push and pull commands is better, as they handle changes more safely.

The author explains the difference between bare and non-bare repositories. Non-bare repos have a working directory (editable files), while bare repos only contain the .git folder (history). Pushing changes is only allowed to bare repos to prevent conflicts.

Their new setup involves creating bare repositories on an external drive connected to their home desktop. Other devices access this drive via SSH. This method allows for seamless syncing across devices without relying on third-party services. While it lacks features like web interfaces and collaboration tools, it suits their needs for personal projects.

The author reflects on their past use of GitHub, realizing that sharing knowledge requires more than just publishing code; it needs to be organized and discoverable. They now focus on creating clear, searchable snippets instead of cluttering GitHub with random code. Ultimately, they find that a simple file-syncing solution is all they need for their personal projects.

Summary of Understanding std::shared_mutex from C++17

This article explains the use of std::shared_mutex, a feature introduced in C++17, for managing concurrent access to shared data. It begins with a simple example of a thread-safe counter using std::mutex, which allows only one thread to access the data at a time, leading to performance limitations in scenarios with many read operations.

Key Points:

1. Limitations of std::mutex:

   • When multiple threads frequently read shared data, std::mutex can become a bottleneck because it requires exclusive access for both reading and writing.
   • This can lead to inefficiencies and reduced performance in read-heavy applications.

2. Introduction of std::shared_mutex:

   • std::shared_mutex allows multiple threads to read data simultaneously (shared ownership) while still providing exclusive access for writing (exclusive ownership).
   • This makes it more suitable for read-mostly scenarios.

3. Refactoring Example:

   • The article shows how to refactor the counter implementation to use std::shared_mutex, enabling concurrent reads without compromising data integrity during writes.

4. Performance Gains:

   • A benchmark comparison demonstrates that using std::shared_mutex significantly reduces contention and improves throughput in read-heavy workloads compared to std::mutex.

5. Realistic Use Case:

   • The shared mutex pattern is especially beneficial in applications like caches, where reads are common and updates are infrequent.

6. Common Pitfalls:

   • Recursive locking with std::shared_mutex is undefined.
   • Upgrading from a shared lock to a unique lock can lead to deadlocks.
   • More locks do not always mean better performance, especially in low-contention situations.

7. Future Concurrency Tools:

   • The article mentions new concurrency features in C++20 and later, but emphasizes that std::shared_mutex remains relevant for specific use cases involving shared data.

In conclusion, std::shared_mutex is a valuable tool for managing concurrent read access while maintaining data integrity during writes, particularly in scenarios where read operations are predominant.

Summary of "Cord: Coordinating Trees of AI Agents"

AI agents excel at specific tasks but struggle with complex, interdependent projects. Current frameworks for coordinating AI agents have limitations, as they often require developers to predefine how tasks should be divided and managed.

1. Existing Frameworks:

   • LangGraph: Models coordination with a static graph that developers set up in advance.
   • CrewAI: Uses defined roles for agents but doesn't allow agents to adapt roles as needed.
   • AutoGen: Agents communicate in a group chat, leading to unpredictable outcomes without a clear structure.
   • OpenAI Swarm: Offers simple handoffs between agents, but lacks parallelism and flexibility.
   • Claude’s tool-use loops: Works well for sequential tasks but can’t handle complex tasks that require parallel processing.

2. The Problem: All frameworks need developers to define workflows, limiting the agents' ability to adapt and optimize their task management based on real-time insights.

3. Introducing Cord:

   • Cord allows agents to dynamically build a tree of tasks based on a given goal. For example, when tasked to evaluate an API migration, an agent identifies necessary subtasks, coordinates them, and engages with human input as needed.
   • It uses two key concepts: spawn (creates a new task with a clean context) and fork (inherits results from sibling tasks), enabling efficient and context-aware task management.

4. Implementation: Cord is built using Claude Code CLI and SQLite, but the underlying protocol can be adapted to different systems and platforms.

5. Testing and Validation: Tests showed that the protocol is learnable, with agents effectively using the defined primitives to manage tasks, recover from errors, and coordinate with one another without explicit instructions.

6. Getting Started: The system can be tried by cloning the repository and running it with specific goals or planning documents.

Overall, Cord represents a shift towards empowering AI agents to autonomously manage complex tasks by dynamically forming their coordination structures.

President Trump has introduced a new 15% global tariff, despite a court ruling that he overstepped his authority in doing so. This decision raises concerns for businesses and US allies, as there is uncertainty about future tariffs. Some countries, like the UK, Mexico, and Germany, are monitoring the situation but remain cautious. There are also questions about refunds for companies that paid the now-illegal tariffs. This new tariff is temporary and will only last 150 days unless approved by Congress.

The blog discusses lessons learned from setting up a cloud-edge testbed for a computer vision demo using Karmada and k3s. The key takeaway is that etcd, a distributed key-value store used by Karmada, is highly sensitive to slow storage.

During setup, the team encountered persistent pod crashes, which led to an investigation that revealed the root cause: etcd was timing out due to inadequate I/O performance from the shared storage on their NUC device.

To fix this, they optimized ZFS settings, such as disabling sync writes, which dramatically reduced write latency and stabilized the cluster.

The main lesson is that if you experience etcd-related crashes, first assess your storage performance rather than just focusing on application-level issues. Proper storage is crucial for the reliable functioning of distributed systems like Karmada.

In 2017, WikiLeaks released Vault7, which included CIA hacking tools and some developer documentation with useful git tips. One key tip helps manage local git repositories by cleaning up stale branches that accumulate over time.

The problem is that git repositories can get cluttered with old branches after merging features. To see which branches are merged, you can use:

git branch --merged

However, deleting them one by one is tedious. The CIA provided a better solution:

git branch --merged | grep -v "\*\|master" | xargs -n 1 git branch -d

Here's how it works:

• git branch --merged lists merged branches.
• grep -v "\*\|master" excludes the current branch and the master branch from deletion.
• xargs -n 1 git branch -d deletes each remaining branch safely.

To adapt this for projects using "main" instead of "master," you can use:

git branch --merged origin/main | grep -vE "^\s*(\*|main|develop)" | xargs -n 1 git branch -d

Running this command after a deployment reduces the number of branches from many to just a few. You can save it as a git alias called ciaclean for easy use:

alias ciaclean='git branch --merged origin/main | grep -vE "^\s*(\*|main|develop)" | xargs -n 1 git branch -d'

This command helps keep your git repository organized and saves time each week.

The article argues that businesses should rethink how they view AI, suggesting it's more effective to see it as an "exoskeleton" that enhances human capabilities rather than as a coworker that operates independently. Companies that treat AI as a tool that amplifies human work are achieving better results compared to those expecting AI to function autonomously.

The author presents the "Exoskeleton Model," where real-world examples show how exoskeletons in various fields—like manufacturing, military, and healthcare—improve human performance. For instance, Ford and BMW have implemented exoskeletons that significantly reduce injuries and labor effort. In military applications, exoskeletons help soldiers carry heavier loads without injury, while in medical rehabilitation, they enable patients with spinal cord injuries to walk again.

The article critiques the trend of developing "agentic AI" that acts independently, highlighting the risks of such systems lacking necessary context, leading to failures. Instead, successful AI integration should involve breaking down tasks, creating specialized micro-agents to assist with specific functions, and keeping humans in control of decision-making.

The author suggests organizations focus on identifying repetitive or strenuous tasks that AI can help alleviate, rather than pursuing full automation. The future of AI lies in tools that seamlessly enhance human productivity rather than replace it. The growth potential in the exoskeleton market reflects this trend of supporting and strengthening workers rather than replacing them.

A recent study has found that using cannabis during adolescence significantly increases the risk of developing serious mental health issues later in life, including bipolar disorder, psychotic disorders, depression, and anxiety. Researchers analyzed data from 460,000 teens and followed them until they were 25 years old, ensuring that those with prior mental health symptoms were excluded from the analysis.

The study revealed that teens who used cannabis were twice as likely to be diagnosed with bipolar and psychotic disorders compared to those who did not use it. Additionally, the risk of developing depression and anxiety increased as well, with depression rising by about 33% and anxiety by 25% among cannabis users.

Experts emphasize that the adolescent brain is still developing, making it more vulnerable to the effects of cannabis. They warn that while many view marijuana as a harmless substance, it can have serious mental health consequences. The findings aim to encourage caution among teens regarding cannabis use.

Scaling language models for long contexts is limited by the size of the key-value (KV) cache. Typically, long contexts are managed by summarizing tokens, but this can lead to a loss of important information, affecting performance. Recent advancements with Cartridges have allowed for the creation of compact KV caches that maintain full-context performance, but this process is slow and costly.

The new approach introduced focuses on fast context compaction in latent space using a method called Attention Matching. This method creates smaller keys and values to replicate attention outputs while keeping attention mass consistent at each KV head level. The process breaks down into simpler subproblems, some of which can be solved efficiently. This framework leads to a range of techniques that greatly enhance the balance between compaction speed and quality, achieving up to 50 times compaction in just seconds on certain datasets with minimal quality loss.

The text discusses the complexities of women's clothing sizes, particularly focusing on how they change from childhood to adulthood.

Key points include:

1. Clothing Sizes for Tweens: Most 11-year-old girls wear a size 9 in the junior's section, which is a medium. As girls age into their mid-teens, they often transition to women's sizes, which can lead to confusion about fitting.

2. Growth and Sizing Changes: By age 15, many girls have reached their adult height and may find that they outgrow junior sizes, moving into women's sizes where options are more diverse but can be inconsistent.

3. Inconsistencies in Sizing: Women's clothing sizes vary greatly across brands and even within the same brand, leading to frustration for shoppers. There are no universal sizing standards, and brands often create their own size charts.

4. Vanity Sizing: Many brands use vanity sizing, where sizes appear smaller than actual measurements to appeal to customers. This practice can distort women's understanding of their true size.

5. Historical Context: The current sizing system was developed based on limited demographic data and has not adapted well to the diverse body shapes and sizes of modern women.

6. Personal Experiences: The author shares her own struggles with finding well-fitting clothes, leading her to learn how to sew and create custom clothing that better fits her body.

7. Industry Challenges: The fashion industry often caters to a narrow definition of body types, excluding many women from accessible sizing, which perpetuates the issue of fitting.

Overall, the text highlights the ongoing challenges women face with clothing sizes and the need for a more inclusive and accurate sizing system that reflects diverse body shapes.

We have adapted pbrt-v4 for Julia and created a backend for the Makie plotting library. This allows any Makie plot to be rendered using realistic path tracing. Julia can compile user-defined physics directly into GPU code, enabling users to add new materials and effects, like a black hole with gravitational lensing in about 200 lines of code. The setup works on AMD, NVIDIA, and CPU systems through KernelAbstractions.jl, with support for Metal coming soon. You can find demo scenes at github.com/SimonDanisch/RayDemo.

Harry McCracken has revived his 1981 adventure game, Arctic Adventure, into a modern multimedia version using AI technology called Claude Code. Originally programmed in BASIC during high school, the game has evolved significantly over the years. The new version, Arctic Adventure 2026, now includes graphics and a more user-friendly interface, making it accessible on the web.

McCracken first updated the game in 2021 and then decided to use Claude Code to convert the original BASIC code into a web-compatible format. The process was surprisingly emotional and collaborative, as he felt he was working alongside his younger self. The initial output from Claude was rough but provided a solid foundation for further development.

The updated game maintains the core elements of the original, including its puzzles and plot, while enhancing features such as robust save options, an "undo death" function, and animated graphics. McCracken also added sound effects and interactive elements, making the game more engaging.

Despite concerns about losing the essence of the original text-based experience, McCracken found that adding graphics didn't detract from the game's charm. He also created a text-only mode for players who prefer the classic format.

Overall, Arctic Adventure 2026 represents a blend of nostalgia and modern technology, showcasing the evolution of gaming from text-based adventures to multimedia experiences. The project has been enjoyable for McCracken, who hopes players will appreciate both the new features and the vintage spirit of the game.

Summary of "Measuring AI Agent Autonomy in Practice"

AI agents are increasingly used in various contexts, ranging from simple tasks like email management to more complex issues like cybersecurity. Understanding how these agents operate and the autonomy they possess is crucial for safe deployment.

Key Findings:

1. Increased Autonomy: The AI agent Claude Code is now able to work autonomously for longer periods, with the time between human interventions nearly doubling in just three months.

2. User Experience Influence: More experienced users tend to allow Claude Code to operate without constant approval, with auto-approvals increasing from 20% to over 40% as users gain familiarity. However, these experienced users also tend to interrupt the agent more frequently.

3. Clarification Requests: Claude Code asks for clarification more often than users interrupt it, especially on complex tasks. This indicates that the AI is actively managing its own uncertainty.

4. Risky Applications: Most actions taken by agents are low-risk and reversible. While software engineering accounts for nearly half of agent activities, there is growing use in fields like healthcare and finance, though not at scale yet.

5. Need for Monitoring: Effective oversight of AI agents requires new monitoring systems and interaction methods that allow both humans and AI to manage autonomy and risk collaboratively.

Challenges in Studying AI Agents:

• There is no standardized definition of what an AI agent is, and their rapid evolution complicates empirical research.
• Visibility into how agents operate in different contexts is limited.

Recommendations:

• Post-Deployment Monitoring: More research is needed to understand how agents are used in real-world settings.
• Training AI for Uncertainty: AI should be designed to recognize when it needs human input.
• User Oversight Design: Tools should empower users to monitor AI actions effectively without mandating specific approval processes.

This research represents a foundational step toward understanding AI agent behavior, emphasizing the importance of empirical studies as AI technology continues to evolve.

The Voith Schneider Propeller (VSP) is a specialized marine propulsion system created by the Voith Group, known for its high maneuverability. It allows ships, especially tugs and ferries, to change thrust direction almost instantly without using a rudder. Invented by Ernst Schneider in 1926, the system features vertical blades that can rotate, enabling thrust in any direction.

The VSP operates by rotating a circular plate with blades extending downwards. As the plate spins, the blades adjust their angles to provide thrust, making the system highly efficient and responsive, ideal for vessels that need precise control. While azimuth thrusters are cheaper initially, VSPs have lower long-term costs and higher residual value.

Historically, the VSP was initially designed for hydro-electric turbines but was adapted for marine use. It gained popularity in the 1930s, with various naval and civilian applications, including minesweepers and ferries. Today, VSPs are used in various ships, including those in the U.S. Navy and French Navy. The system has also been explored for use in drones and experimental aircraft.

Summary:

In 2026, concerns were raised about Bluesky, a platform built on the ATProto open protocol. The main promise of Bluesky is that users own their data and can easily leave if they dislike the platform. However, most users rely on Bluesky's servers to store their data, making it difficult to switch to alternatives.

As more apps connect to Bluesky, dependence on its infrastructure grows, increasing the challenges for users who want to leave. Bluesky controls critical components like the data relay, timeline assembly, and user identity directory, which could hinder users if the company were to change its policies or be acquired.

Despite the technical possibility of self-hosting and migrating data, history shows that most people do not take these actions, leading to centralization. The concern is that if Bluesky were bought, the new owner could restrict data access and change how the platform operates, affecting all connected apps.

While Bluesky's team seems well-intentioned, the financial pressures from investors could lead to control consolidation rather than decentralization, undermining the original promise of user autonomy.

The author shares their experience building a startup using European infrastructure instead of relying on American providers like AWS. They aimed for data sovereignty, simplicity with GDPR compliance, and to support EU companies.

Key points include:

• Infrastructure Choices: The author chose Hetzner for compute resources, Scaleway for additional services (like transactional email and domain registration), and Bunny.net for CDN and security. They also self-host various tools for source control, analytics, and customer management using Kubernetes.

• Challenges Faced: Finding a competitive European option for transactional email was tough, as existing services like Sendgrid are easier and cheaper. Leaving GitHub was emotionally challenging, as it required rebuilding workflows. Additionally, domain prices were unexpectedly high with EU registrars.

• Inevitabilities: Some services, like Google Ads and Apple’s Developer Program, are unavoidable for user acquisition and app distribution. Social logins also require American servers, though a German provider, Hanko, helps manage user accounts locally.

• Final Thoughts: Despite the challenges, the author found the experience worthwhile. Infrastructure costs were lower, and they have a better understanding of their stack. However, it requires significant effort to choose EU alternatives over American defaults. The EU tech ecosystem is growing, but it's important to be prepared for the work involved in this choice.

Summary:

Git tracks files but not directories. To ensure a directory exists in a repository, two methods can be used: the .gitkeep technique and a simpler .gitignore method.

1. .gitkeep Technique:

   • Involves creating an empty file named .gitkeep in the directory.
   • Requires editing both .gitkeep and .gitignore files to track the directory.
   • If the directory is renamed, you must update .gitignore, which can be overlooked.
   • There's no official recognition of .gitkeep, which may confuse developers.

2. Better .gitignore Technique:

   • Uses a .gitignore file inside the directory instead.
   • The .gitignore file contains two lines: one to ignore all files and another to un-ignore itself.
   • This approach is simpler, requires only one file, and remains effective even if the directory is renamed.

In conclusion, using .gitignore is a more efficient and straightforward method for tracking directories in Git.
