Summary of Bachelor Thesis Extended Abstract

The author worked on a bachelor thesis about operating system development, which was completed six months ago but is still part of their role as a student research assistant. Initially, the project involved coding for an internal research kernel, but it has now been adapted to an open-source kernel called eduOS, which is used for educational purposes at their university.

The thesis discusses a technique for managing memory in x86 architectures, specifically using "self-referencing page tables." This method simplifies the handling of virtual address spaces (VAS) by allowing the operating system to access page tables directly without complex mappings. This results in shorter and more maintainable code, supporting both 32-bit and 64-bit systems with a single codebase.

The key innovation is that by adding a self-reference in the root page table, the need for manual mappings is eliminated, which reduces complexity and memory usage. The author explains how this self-reference works and shows that it maintains essential memory protection properties.

Despite the thesis's rejection from a research competition, the author sees this as an opportunity to share their findings with a broader audience. Full details, including a PDF of the extended abstract, are available for download.

The Fisher-Yates shuffle is a well-known algorithm for shuffling a list, ensuring that each possible arrangement is equally likely. The standard implementation, called the Fisher-Yates shuffle, works by iterating backward through the list and swapping elements based on a random index.

However, the author proposes a simpler version called the "forward shuffle," which iterates forward through the list. The main difference is in the direction of the loop, but both methods achieve the same result of uniformly shuffling the elements.

The forward shuffle, like the Fisher-Yates shuffle, maintains that after each iteration, the portion of the list processed is a random permutation of the original elements. The author also discusses an "inside-out" version that works similarly for lists generated from other sources.

Overall, the text highlights the validity of the forward shuffle and suggests it might be more straightforward than the traditional approach, questioning why it isn't more commonly used.

Summary: CSRF Protection without Tokens or Hidden Form Fields

In December 2025, the author explored implementing Cross-Site Request Forgery (CSRF) protection for their web framework, Microdot. Initially, they planned to use traditional methods like anti-CSRF tokens, but discovered a simpler, modern approach.

The new method leverages the "Sec-Fetch-Site" header, which modern browsers include in requests. This header indicates the request's origin and can be trusted, allowing servers to reject cross-site requests. The author implemented this approach after researching its validity and compatibility.

However, they acknowledged challenges, such as users on older browsers that don't support this header. To address this, they decided to use the "Origin" header as a backup. They also integrated existing Cross-Origin Resource Sharing (CORS) support to manage allowed origins.

The author noted that the OWASP CSRF Cheat Sheet was updated to include this method but initially categorized it as a secondary defense rather than a primary solution. They believe the new approach aligns with the minimalist philosophy of Microdot and plan to monitor further developments in OWASP guidelines.

Overall, the author found this journey rewarding and educational, transforming a tedious task into an exciting opportunity for learning and growth in open-source development.

The author started the Selenium project 21 years ago and has now created a new project called Vibium, designed for modern AI agents. Vibium runs in the background (managing browsers and other tasks), but developers only need to use a simple command: "npm install vibium." Versions for Python and Java are coming soon. For Claude code integration, the command is "claude mcp add vibium -- npx -y vibium." The first version is released today, and the author invites questions.

A McMaster University research team has created a new public database called the Canadian Notifiable Disease Incidence Dataset (CANDID), which digitizes over 100 years of Canadian infectious disease data. This dataset includes more than a million records dating back to 1903 and covers diseases like polio, hepatitis, and influenza. It provides detailed weekly, monthly, and quarterly case counts across provinces and territories.

The project began when Professor David Earn discovered old epidemiological documents at the Ontario Ministry of Health. With support from a recent grant, his team worked to curate and organize this data for analysis. The new dataset aims to improve understanding of past disease outbreaks and enhance public health preparedness for future epidemics.

Earn highlights that the current infectious disease reporting in Canada is limited, as it only provides annual national counts, which hinders research. He advocates for better data sharing practices that protect patient privacy while allowing more detailed information to be available for public health research.

The text discusses the author's attempts to port a Perl library called Graph::Easy, which creates ASCII art flowcharts, to the web.

Key points include:

1. Inspiration: The author was inspired by Simon Willison's use of a tool called Claude to bring older libraries to the web and wanted to do the same with Graph::Easy.

2. Initial Success: The author successfully created a web app using Claude to run Graph::Easy locally but faced challenges when trying to port the library to TypeScript.

3. Challenges Faced:

   • The first attempt failed because the ASCII output did not match the original.
   • Subsequent attempts involved a Test Driven Development (TDD) approach, but many tests failed due to the complexity of ASCII rendering, which large language models (LLMs) struggle to understand.
   • The author tried breaking down the work into simpler tasks but still faced issues with accuracy.

4. Frustration: The process was exhausting, leading to confusion and dissatisfaction with the progress. The author felt overwhelmed by the complexity of the original library and the limitations of the AI tools.

5. Realization: Ultimately, the author recognized that the complexity of Graph::Easy was a result of years of development, which cannot simply be replicated by AI. They concluded that replicating such intricate work requires a deep understanding of the craft, something that AI alone could not achieve.

The text emphasizes the challenges of using AI for complex programming tasks and the importance of respecting the intricacies of established codebases.

The author is returning their Framework laptop due to dissatisfaction with its performance and design. They currently own an older X1 Carbon laptop, which has keyboard issues and has been frustrating to maintain. After considering several options for Linux-compatible laptops, they chose the Framework due to its upgradable and repairable features.

The author purchased the Framework 16 model, appreciating its larger size compared to their X1 Carbon. However, they found the assembly process straightforward but noted several design flaws, such as a bulky weight, poor display quality, overly bright power LED, and disappointing speakers. The laptop's performance was decent, but issues like flickering display and battery drain during sleep were concerning.

Ultimately, the author believes the Framework 16 does not justify its high price of around €2000, feeling it lacks the premium quality expected at that cost. They have requested a return and are unsure what to replace it with, considering other brands that also have similar issues. For now, they will continue using their X1 Carbon.

Summary:

Prototaxites was an ancient, extinct group of large multicellular organisms that lived on land during the Early Devonian period, reaching heights of up to 8 meters. Its classification has been debated for over 165 years, with suggestions of it being either a type of fungus or a completely unique lineage. Recent research indicates that Prototaxites, specifically Prototaxites taiti, is fundamentally different from known fungi, both in its anatomy and molecular structure.

Studies show that its cell walls contain materials similar to lignin, rather than chitin, which is found in all fungi. Therefore, researchers conclude that Prototaxites is not a fungus but belongs to an entirely separate, extinct group of terrestrial life.

The blog post by Kate W. discusses the variations of the playground song "Jingle Bells (Batman Smells)." Kate asked people on BlueSky about their memories of the song, revealing a wide range of different versions.

She noted that many American versions center around a specific rhyme involving Robin laying an egg, while UK versions feature more diversity, with Robin often flying or running away. A significant difference is that American versions are more clustered around a single popular form, likely influenced by its appearance in "The Simpsons," while UK versions are more varied and often include local references.

Kate also highlights the historical background of "Jingle Bells," originally composed in 1857, and speculates on how children's adaptations of the song may have evolved over time. She humorously mentions a rare version without Batman, suggesting that some variations may be "living fossils" of older rhymes.

In conclusion, she invites readers to enjoy the diversity of these playful adaptations and wishes everyone a Merry Christmas.

A controversial segment of CBS's "60 Minutes," called "Inside CECOT," has gained attention after being blocked from airing by CBS editor-in-chief Bari Weiss. The report included testimonies from U.S. deportees who suffered abuse in a Salvadoran prison. Weiss pulled the segment, claiming it lacked critical voices, specifically from Trump officials, and did not contribute new information.

Despite this, the segment continued streaming in Canada, allowing viewers to access it through a VPN. Critics quickly shared the report online, including on file-sharing sites and the revived service LimeWire, which was once notorious for piracy. This led to jokes on Reddit about LimeWire’s unexpected comeback as a tool for bypassing censorship.

Weiss’s decision has faced backlash, raising concerns about journalistic integrity and the influence of political pressures on news reporting. CBS staff and industry observers criticized the move, suggesting it undermined the independence of the newsroom.

Summary:

A new AI lab, Odyssey, is developing a general-purpose world simulator that learns to predict how the world changes over time using large amounts of video and interaction data. This approach uses simple prediction tasks, like forecasting the next frame of a video, to build models that understand complex structures such as causality and dynamics without needing pre-defined rules.

The world simulator, named Odyssey-2, learns from observations rather than hand-crafted simulations, allowing it to adapt and predict a wider range of phenomena. This model is designed to maintain internal states over time, which is crucial for making accurate predictions about long-term scenarios.

Current simulators are often limited to specific tasks, but Odyssey's approach enables a more flexible, general simulation that can evolve based on user interactions. This allows for real-time, interactive simulations where users can engage continuously and see immediate results.

The goal is to create a comprehensive tool that can test cause and effect in complex systems without needing separate models for each scenario. Odyssey is open to collaboration with researchers interested in advancing this innovative approach to world simulation.

Summary of rules_img for Bazel Container Images

On December 18, 2025, Malte Poll introduced rules_img, a new approach for building container images in Bazel that improves efficiency and speed. Here's a simplified overview:

The Problem: When using Bazel to package applications into Docker containers, builds often become slow due to the large amount of base image data being downloaded and uploaded. This can hinder continuous integration (CI) performance.

Key Components:

1. Registry: A server (like Docker Hub) that stores container images.
2. Local Machine: Where Bazel builds run.
3. Remote Execution/Cache: Servers that execute Bazel actions and cache results.

How rules_img Works:

• Minimal Data Transfer: Instead of downloading entire base images, rules_img focuses on pulling only the essential metadata (like manifest and config), which is only about 10 KB. The actual image layers stay in the registry until needed.
• Layer Creation: Layers are built and stored in a way that only metadata is handled during the build phase, allowing for faster processing and better caching.
• Efficient Pushing and Loading: During the runtime phase, rules_img checks the registry for existing blobs and only transfers the missing ones, streamlining the push process.

Benefits:

• Speed: Pulling and pushing images is significantly faster, reducing build times from minutes to seconds.
• Efficiency: Less data is moved during builds, improving CI performance and reducing unnecessary uploads.
• Simplified Processes: The system treats images more like metadata, which allows for more efficient handling of container images within Bazel.

Conclusion: rules_img aims to make the process of working with container images in Bazel faster and more efficient, resulting in better performance in CI environments and a smoother experience for developers. For those looking to implement this, a quick start guide is available on their GitHub page.

Summary: Avoid Mini-Frameworks

What are Mini-Frameworks? Mini-frameworks are small frameworks created by teams to address specific issues in a shared tech stack. They introduce new concepts and often claim to simplify development but can cause more problems.

My Experience: The author shares their experience working with a mini-framework at Google. A team decided to add an abstraction layer to an existing framework to make it easier to use, but this led to complications, slower development, and frustration among team members.

Why Mini-Frameworks Are Problematic:

1. Incomplete Features: They often fail to cover all use cases and can lack necessary flexibility.
2. Difficult to Change: They only address current needs and may struggle to adapt to future requirements.
3. Personal Bias: They reflect the creator’s mental model, which may not align with others' ways of thinking.
4. Tech Fragmentation: They can lead to inconsistent codebases as different teams use different frameworks.
5. Lack of Maintenance: They often rely on a few individuals, making them vulnerable when those people leave.

What to Do Instead:

• Avoid Mini-Frameworks: Focus on creating libraries that don’t introduce new concepts.
• Justify Framework Creation: If a framework is necessary, ensure it ties closely to business needs and build it from scratch rather than wrapping existing frameworks.
• Take It Seriously: Understand the implications of creating frameworks and treat the process with the seriousness it deserves.

In summary, it's crucial to be cautious when introducing new frameworks and to prioritize clarity and maintainability in software development.

Summary: How I Left YouTube

The author shares their experience of leaving YouTube after struggling to get promoted despite significant contributions. They were working at a level much higher than their official title, which affected their salary and recognition. After multiple failed promotion attempts, they decided to seek a new job that would reflect their true worth.

Job hunting while still employed was challenging, requiring a lot of effort and time management. They had to navigate strict Non-Disclosure Agreements (NDAs) to present their skills without revealing sensitive information. The author learned to focus on general engineering principles instead of specific projects.

They faced a long interview process, particularly at one company that required 13 interviews, signaling potential issues within its hiring culture. The author had a heartfelt conversation with their manager when resigning, expressing that they needed to grow beyond their current role.

In the end, the author emphasizes that leaving a well-known company can be daunting, but staying in a role that doesn’t match your capabilities can hinder progress. They encourage others feeling similarly to consider testing the job market for better opportunities.

In a recent project, the author created a shoot ’em up game in just 7 days, resulting in a small 3kB Windows executable. This was part of the Langjam Gamejam, where participants create a programming language and use it to develop a game. The author’s interests in language design, game development, and size constraints motivated this project.

The plan included designing a language, implementing a compiler in F#, creating a bytecode interpreter in C++, and rendering graphics using a single shader. The game’s size was kept minimal by avoiding music and 3D graphics.

A live-coding workflow allowed for instant feedback during development, making it easier to iterate on the game. The bytecode design was minimalist, using only float arrays and two types of statements: updating array cells and jumping to other instructions. The language supported basic structures like assignments and loops but was kept simple to fit the size constraints.

The game design features infinite gameplay, starting with three enemies and increasing their number over time. Enemies are teleported out of the game instead of being destroyed when hit, simplifying the code. The quick iteration process was crucial for development, revealing necessary features as the game was built.

In a comparison, the bytecode version of the game was even smaller than a C++ version without the interpreter, demonstrating the efficiency of the bytecode approach. Overall, the project was enjoyable and provided valuable learning experiences, with the author looking forward to future game development explorations.

The text discusses how to effectively manage email and small tasks that can disrupt focus, likening the inbox to a "bandit" that steals time and concentration. Here are the key points:

1. Inbox as a Bandit: Similar to choosing between slot machines, deciding which emails to read can be mentally exhausting. It often leads to suboptimal choices and distractions.

2. Common Strategies: Techniques like Inbox Zero and Getting Things Done are popular but may not suit everyone. The author prefers a more personalized approach.

3. Personal Context: The author manages a single inbox and often receives small, low-priority tasks via email that disrupt concentration.

4. Snoozing Emails: Using email snooze functions hasn’t worked due to overthinking, unexpected tasks, and distractions from other emails.

5. Proposed Solution: The author created a new Gmail label called "DBTC" (Death By a Thousand Cuts) for non-urgent tasks. Emails that distract but don’t need immediate attention can be moved here, reducing visual clutter.

6. Processing DBTC: The author sets aside specific times to process this folder, allowing focused attention without distractions from other emails.

7. Extending the Concept: The DBTC approach is applied to other communication tools and task managers to streamline handling of non-urgent tasks.

8. Conclusion: This method has proven effective for the author since March 2021, and they hope others find it useful too.

In 1996, while developing Quake, the team faced challenges due to the limitations of early internet downloads. They set a maximum size of 1.4 megabytes for map files, called BSP files, which meant they had to carefully manage the complexity of the levels. If the polygon count exceeded 350, a flickering screen would alert them, prompting changes to keep the game's performance smooth.

The level editor, QuakeEd, was basic and difficult to use, involving a 3D rectangle "brush" that they manipulated to create the game’s environments. They had limited viewing options, which made the design process time-consuming.

To maximize gameplay within the size constraints, John Carmack decided to reduce the player's speed, allowing players to take longer to complete levels. This decision was influenced by the need to keep levels smaller and more manageable due to the file size limit, ultimately enhancing the game's overall experience.

The text discusses the use of the [[nodiscard]] attribute in C++17, particularly in the context of the libc++ library. This attribute warns programmers when a function's return value is ignored, which can help catch bugs. While some functions, like malloc, should always be marked with [[nodiscard]], others, like unique_ptr::release, are often left unmarked because they can be validly used for their side effects.

Recently, there was a proposal to mark the map::operator[] function as [[nodiscard]]. However, it was discovered that many codebases, including Google's, use this operator for its side effects, making the attribute inappropriate in those cases. For example, the operator might be used in a way that checks if a key exists in a map without intending to use the return value, which could lead to confusion if the code were refactored incorrectly.

Ultimately, libc++ decided to remove the [[nodiscard]] attribute from map::operator[] after realizing it could cause more confusion than benefit. The text advises developers to avoid the idiom of using m[key]; and suggests replacing it with m.try_emplace(key); or using (void)m[key]; to clarify intent and improve code quality.

Scientists have discovered that Ötzi, a 5,000-year-old mummy found in the Alps, and a 45,000-year-old Homo sapiens fossil from Siberia contain DNA from the cancer-causing human papillomavirus (HPV16). This finding suggests that humans have been infected by HPV for a very long time, possibly since modern humans encountered the virus around 60,000 years ago, potentially through interbreeding with Neanderthals.

HPV is common, with many types causing no harm, but some can lead to cancers. Vaccines have been available since 2006 to prevent the most dangerous types. However, there are concerns that other HPV types may increase in the absence of the targeted ones.

The research team, led by Marcelo Briones, analyzed DNA sequences from Ötzi and another ancient human fossil, finding evidence of HPV16. They ruled out random occurrences and confirmed that the virus has been circulating among humans for thousands of years. This challenges the notion that HPV was primarily introduced to humans through Neanderthal interbreeding.

While these findings enhance our understanding of HPV's history, they may not directly lead to improved vaccines or treatments.

Summary of X-Ray Library

X-Ray is a Python library designed to identify poorly executed redactions in PDF documents. At Free Law Project, we handle millions of PDFs, and a common issue is that users often fail to properly redact sensitive information. Instead of securely removing text, they simply cover it with a black rectangle, which can still allow the text to be read underneath.

To address this problem, we developed X-Ray, which analyzes PDFs and detects ineffective redactions. Users can run the tool by providing a PDF file path or a URL, and it will report any bad redactions found.

Installation and Usage:

• Install X-Ray using:
  • uv add x-ray or pip install x-ray.
• Use the command line to analyze PDFs:
  • For local files: xray path/to/your/file.pdf.
  • For online files: xray https://example.com/file.pdf.
• X-Ray outputs results in JSON format, showing the page number, rectangle position, and text found under bad redactions.

Technical Details: X-Ray utilizes the PyMuPDF library to parse PDFs. It identifies rectangles, checks for text within those areas, and assesses the color uniformity to determine if a redaction is valid. Although X-Ray works effectively, there is room for improvement, and contributions are welcome.

Contributions and Deployment: Contributors can find tasks on the GitHub issues list and are required to sign a contributor license agreement. Releases are automated through GitHub Actions, and manual version updates are also supported.

License: X-Ray is released under a permissive BSD license, making it easy to use in other projects.

The text describes a C program that appears to print the squares of integers from 1 to 10 but actually outputs a grilled salmon recipe. This code, written by Adrian Cable, won a prize in the International Obfuscated C Code Contest (IOCCC). The author initially found the code confusing because it uses obfuscation techniques, making it hard to see its true purpose.

Key points include:

1. Obfuscated Code: The program uses complex macros and encoding to hide its true output, which is a recipe rather than the expected mathematical results.

2. Understanding the Code: The author explores the code step by step, focusing on elements like binary and hexadecimal representation, C macros, and pointers. They used tools like cat -v to reveal hidden characters in the source code.

3. Decoding Process: The recipe text is encoded in UTF32, with the program using only the last 8 bits of each character for output. The author learns how to decode the string and understands that hidden characters represent the recipe.

4. Logic Behind Output: The program's structure leads to the recipe being displayed only once, followed by the failure to print the squares of integers due to the way the loops are nested.

5. Learning Experience: The author emphasizes the importance of understanding encoding and obfuscation in programming, highlighting that even experienced programmers can struggle with such techniques.

In conclusion, the text illustrates a journey of decoding a cleverly obfuscated C program, transforming a simple appearance into a complex understanding of programming concepts and techniques.

The article discusses effective testing strategies for complex applications, especially in Go programming. Here are the key points:

1. Mocking vs. Integration Testing: There is a debate about using mocks in testing. Some view mocks negatively, suggesting they can lead to unreliable tests (mock drift). However, the author argues that mocks are essential for managing complex systems without dedicated QA.

2. The Tactical Pair Strategy: The author introduces a strategy combining Contract Tests and Scenario Mocks:

   • Contract Tests ensure that code interacts correctly with real databases and APIs. They verify that the system's structure matches expected behavior.
   • Scenario Mocks allow testing of specific logic and error handling scenarios that are difficult to reproduce in real environments.

3. Designing for Testability: Good design practices, such as using interfaces instead of concrete implementations, enhance testability. This separation allows easier mocking and better management of dependencies.

4. End-to-End Tests: While Contract Tests are valuable, they do not replace End-to-End (E2E) tests. E2E tests validate that the entire system operates correctly in real-world conditions.

5. Practical Tools: The article mentions useful Go packages for testing, such as:

   • testify/mock for creating mocks and assertions.
   • httpmock for intercepting HTTP requests and simulating API responses.
   • go-sqlmock for occasional use with SQL logic.

In summary, combining Contract Tests with Scenario Mocks improves testing reliability and coverage, enabling developers to manage complex applications effectively.

Summary: What Makes a Senior Engineer?

Senior engineers are often defined by skills like architecture, communication, and leadership. However, the most important skill that sets senior engineers apart is their ability to reduce ambiguity.

While mid-level engineers excel at tackling clear problems, they struggle when faced with vague issues like improving performance or addressing user complaints. Senior engineers thrive in these situations because they:

• Ask insightful questions.
• Distinguish critical information from irrelevant details.
• Prioritize tasks effectively.

This skill helps them clarify complex problems, ultimately making projects run smoothly with fewer surprises. Unfortunately, many companies focus on technical skills and years of experience in hiring, overlooking the ability to manage ambiguity.

To assess if you're operating at a senior level, consider how you handle unclear tasks. Do you wait for clarification, jump into coding, or take the time to clarify the problem before proceeding? If you do the latter, you're likely already at a senior level. If not, you can improve this skill through practice by tackling ambiguous tasks.

Lockfiles used by various package managers (like npm, Bundler, and Cargo) serve a similar purpose to Software Bills of Materials (SBOMs) by recording which packages are installed, their versions, checksums, and sources. However, they use different formats. Standardized formats like CycloneDX and SPDX are being pushed in the security field for describing software components.

Lockfiles can be thought of as SBOMs since they contain key information like package identity, integrity checks, dependencies, and metadata. Still, there are gaps when comparing lockfiles to CycloneDX, especially regarding how they handle development versus production packages, platform-specific packages, and the distinction between direct and transitive dependencies.

If package managers adopted a standard lockfile format like CycloneDX, it could eliminate the need for conversion tools, improve cross-ecosystem compatibility, and provide first-class SBOMs. However, there are challenges, such as loss of human readability, increased complexity in managing diffs, and the need for migration.

Many package managers already generate SBOMs, and there's potential for gradual adoption of CycloneDX as a lockfile format. This would involve standardizing how package managers use properties and allowing projects to choose whether to adopt the new format.

Overall, recognizing that lockfiles are crucial software supply chain artifacts is essential. They should be treated with the same level of importance as SBOMs to ensure integrity and security across software components.

Summary of SCTP and Its Applications

SCTP (Stream Control Transmission Protocol) is a communication protocol that ensures reliable data transfer between computers. It can send messages in the correct order or out of order, supports multiple applications on a single connection, and provides automatic failover if a primary connection fails.

Key Uses of SCTP:

1. Data Transmission: SCTP allows users to send text messages and larger files, like images and videos, without delays, even when multiple transfers occur simultaneously.
2. Real-time Communication: It enables quick responses for applications like remote surgery and real-time navigation, where low latency is crucial.
3. Online Gaming: SCTP is beneficial for multiplayer games where every moment counts.
4. WebRTC: SCTP is utilized in WebRTC for reliable and secure data transfer, supporting features like video calls and file sharing.

Loss Recovery Strategies in SCTP: SCTP has two main methods for recovering lost data:

• Fast Retransmission: If a data chunk is missing, the receiver informs the sender, which will resend the missing chunk after three reports of loss.
• Timer-based Retransmission: If the sender doesn't receive acknowledgment within a specific time, it will resend the unacknowledged data.

RACK Implementation: A new algorithm called RACK (RACK-TLP) improves loss detection and recovery in SCTP. It:

• Tracks network conditions to identify lost packets more efficiently.
• Uses Tail Loss Probing (TLP) to quickly check if the receiver got the last packet, avoiding unnecessary retransmissions.

Performance Improvements with RACK: Tests show that RACK can significantly increase throughput and reduce CPU usage, leading to faster data transfer without additional resource costs. For example, it improved goodput by 34.9% while using 21% less CPU time.

Future Developments: Researchers are continually refining SCTP and RACK, aiming for even better performance and reliability based on real-world data.

In the spring of 1977, Donald E. Knuth sent a letter to Peter van Emde Boas, sharing his classroom notes on priority deques, which addressed a problem related to their excessive space usage. This correspondence was in response to a report from the University of Amsterdam that presented a solution to this issue. Knuth's note is significant because it includes a famous quote about program correctness and is the first to describe priority deques using a top-down recursive method, which is now widely used. The recursive approach was not initially explored due to concerns about certain machine instructions. The letters exchanged between Knuth and van Emde Boas discuss these topics. The document is being made available online for broader access.

The court ruled that the university administrators violated his rights by punishing him for his speech, which is protected under the Constitution.

Reges, who has taught at the university since 2004, criticized the official land acknowledgment statement and included a parody in his syllabus. This led to an internal investigation and threats of disciplinary action from the university, which claimed his comments disrupted the learning environment for Native American students.

The court emphasized that disagreement and debate are important in higher education and that discomfort from students does not justify punishing a professor for their views. The ruling was seen as a victory for academic freedom, stating that universities should not force faculty to align with specific political viewpoints.

Ultimately, the court found that the alleged disruptions were mainly due to students' discomfort with Reges' opinions, which do not warrant restrictions on his academic speech. The ruling reinforces the idea that exposure to differing views is an essential part of education.
