In a legal case against Google, Y Combinator (YC), a prominent startup accelerator, submitted a brief supporting the plaintiffs. YC argues that Google's monopoly limits opportunities for startups and stifles innovation. They emphasize that open competition is vital for a healthy tech ecosystem and that effective antitrust enforcement, especially during technological shifts like the AI revolution, is essential.

YC highlights that Google’s behavior has created a "kill zone" around its market, deterring investment in innovative startups. They believe that a robust remedy could help new companies thrive and compete effectively. YC suggests that remedies should include granting access to Google's datasets and preventing the company from using its power to block competitors. Their experience has shown that antitrust actions can revitalize markets, as seen in historical cases like the 1956 AT&T decree, which spurred innovation by allowing smaller firms to compete. Overall, YC advocates for strong antitrust measures to foster a more dynamic and competitive tech landscape.

Summary of "The Deathbed Fallacy"

The "Deathbed Fallacy" refers to the idea that people regret not living differently as they approach death, often wishing they had spent more time with family or traveled more. This notion is popularized by figures like palliative nurse Bronnie Ware, who identified common regrets, including not living authentically and working too hard.

However, the author argues that it's misguided to assume that the perspective of your deathbed self should dictate how you live now. Here are three main reasons why:

1. Unreliable State: The mindset of someone on their deathbed is shaped by their imminent death, limiting their view of life. They lack a future and are influenced by recent memories, which may not accurately reflect what would have led to a fulfilling life.

2. Misunderstanding Past Selves: People often think they understand their younger selves, but as they grow, they realize their past decisions were often reasonable given their circumstances. Present selves may judge past choices harshly, overlooking the complexities of those times.

3. Changing Contexts: The values and challenges of previous generations differ significantly from those today. What may have been a struggle for older generations may not apply to younger ones, making it essential to consider current societal contexts when reflecting on life choices.

In conclusion, while the Deathbed List offers valuable insights, it can unfairly blame individuals for prioritizing work or relationships. Instead of focusing on what your future self might think, the author suggests looking at happiness research that emphasizes stable income, relationships, and personal fulfillment. Prioritize your current life choices based on what will lead to happiness now and in the future, rather than worrying about the judgments of an older version of yourself.

This text discusses a bug found in Chromium browsers that allows a simple JavaScript code snippet to crash headless browsers like Puppeteer and Playwright. The idea is that this crash could be used to detect bots, as human users would not be affected. The example code demonstrates how the crash occurs when attempting to open a popup from an iframe.

However, the article warns against using this method in production for several reasons:

1. User Experience: Triggering unexpected popups can frustrate users and disrupt their browsing experience.

2. Performance Issues: This method could lead to increased CPU usage and other side effects that negatively impact website performance.

3. Detection vs. Response: Merging detection with a drastic response (like crashing a browser) limits flexibility in how to handle potential bots.

4. Data Limitations: Client-side detection loses valuable metadata that could help make better decisions about user behavior.

5. Bot Adaptation: Bots can evolve and bypass this detection method, making it less effective over time.

In conclusion, while the idea of crashing bot browsers is appealing, it is not practical or wise for use in real-world applications. Instead, effective bot detection should be subtle, efficient, and resilient to changes in bot behavior. The author suggests keeping the bug in mind for testing purposes but advises against using it in production environments, especially where it could affect search engine crawlers like Googlebot.

Summary of MCP Analysis

Overview: MCP (Model Context Protocol) is designed to standardize how applications connect with large language models (LLMs), similar to how USB-C connects various devices. Despite its promise, the implementation and documentation of MCP have been criticized for lacking maturity and clarity.

Current Situation:

The ALICE collaboration at CERN's Large Hadron Collider (LHC) has successfully measured the transformation of lead into gold through high-energy collisions of lead nuclei. This process, which was once a dream of alchemists, occurs when lead nuclei come close to each other, creating strong electromagnetic fields that can eject protons and form gold nuclei.

In these collisions, the intense electromagnetic field can cause interactions that lead to the loss of protons from lead, resulting in the production of gold nuclei, albeit in very small quantities. During the LHC's Run 2 (2015-2018), approximately 86 billion gold nuclei were created, weighing just 29 picograms, a minuscule amount compared to what would be needed for jewelry.

While the production of gold at the LHC is a scientific achievement, it does not lead to any financial gain, as the amounts are trivial. The findings also enhance our understanding of nuclear physics and could improve future collider performance.

Researchers have found the remains of two cats—one adult and one juvenile—on a Spanish shipwreck called Emanuel Point II, which sank in a hurricane in 1559 near Florida. This discovery suggests these cats may be the earliest known domestic cats in the United States.

The ship was part of an expedition led by Tristán de Luna y Arellano. The cats were likely brought on board to control rodents and may have been well-cared for by the sailors, who possibly fed them a diet of fish and meats. This finding contradicts the idea that cats were brought on ships for food or fur, as they seemed to have received affection from the crew.

Cats were first domesticated around 12,000 years ago and spread to the Mediterranean by 400 B.C.E. While Columbus is known to have traveled with animals to the Americas, the cats from the Emanuel Point II ship are among the first to reach what is now the U.S., and genetic tests confirm they have European ancestry.

The Siemens PC 100 Assembly Manual from 1980 includes unusual "illegal" opcodes for the 6502 microprocessor, which intrigued home computer users. The Siemens PC 100 is a single-board computer designed for education and development, based on the Rockwell AIM-65. The manual, primarily in German and adapted from Rockwell's original, features sections on programming and includes special instructions not found in the original sources.

The main issue being discussed is that Sorbet's syntax is considered unattractive and verbose, which frustrates users. The speaker, Jake, agrees with this criticism but emphasizes that the meaning of types (semantics) is far more important than their appearance (syntax). He believes that types help programmers clearly express their thoughts and prevent errors in code.

Jake explains that many complaints about syntax might stem from a dislike of static typing itself, not just Sorbet's implementation. He wants to address users who appreciate Sorbet's semantics but have concerns about its syntax.

The talk will cover:

1. The history of Sorbet's development at Stripe and the demand for static typing.
2. The challenges faced and decisions made in designing Sorbet's type syntax.
3. Possible future improvements to the syntax.

Jake has been working on Sorbet for almost seven years and shares insights from his experience. He notes that Sorbet was created in response to engineers at Stripe asking for better documentation and static typing. Previous attempts at type checking in Ruby led to the development of Sorbet's current syntax, which aims to provide both runtime and static type checking.

He discusses various approaches to type syntax that were considered, including:

• Adding types on top of Ruby (like TypeScript) which would disrupt existing workflows.
• Creating separate header files for types, which would be incomplete without explicit type casts.
• Using comment-based types, which wouldn't support the runtime checking needed in Ruby.
• The DSL approach used in Sorbet, which allows for runtime checking and has evolved over time.

Jake also mentions future directions for Sorbet’s syntax, including potential improvements that could make it more user-friendly while maintaining compatibility with Ruby. He suggests exploring the integration of RBS comments into the Ruby VM for better type annotation support. Overall, he remains positive about the future of typing in Ruby.

The National Science Foundation (NSF) is undergoing significant changes, including the elimination of its 37 divisions and a major reduction in programs. This restructuring follows a proposal by President Trump to cut the NSF's budget by 55% for the upcoming fiscal year. Current division leaders may lose their positions and face reassignment, while many staff members could receive layoff notices soon.

The NSF plans to consolidate its operations into eight smaller directorates and is expected to cancel many previously awarded grants, totaling over $1 billion. The agency aims to lower the number of senior executive roles and create new non-executive positions to better fit its needs.

Additionally, a new vetting process for grant proposals is being introduced, focusing on compliance with presidential directives about diversity and inclusion. Even if a proposal is approved by a division director, it will undergo further review to ensure it meets the agency's new standards.

This situation has raised concerns about the NSF's ability to fund research independent of political influence.

Understanding these solar cycles and their implications is vital for both Earth and future missions beyond our planet.

AI chatbots, like those from OpenAI and Google, have received updates aimed at improving their accuracy, but recent tests show they are actually making more mistakes, known as "hallucinations." Hallucinations occur when AI provides false information or irrelevant answers. For example, OpenAI's newer models had hallucination rates of 33% and 48%, compared to 16% in an earlier version.

This issue is not unique to OpenAI; other models have also shown increased hallucination rates. Despite efforts to reduce these errors, AI companies are struggling with this persistent problem, which complicates the usefulness of AI for tasks like research or customer service.

Experts note that the term "hallucination" is misleading, as it suggests that errors are rare exceptions, while in reality, AI systems often produce incorrect outputs. Additionally, simply increasing training data and computing power has not solved the problem.

As a result, users may need to be cautious when relying on AI for accurate information, sometimes opting to fact-check AI responses or avoid using it for factual inquiries altogether.

The viral footage claiming to show a three-year-old chimney sweep has been debunked. While many were upset by the idea, the video is staged. It originates from the British Pathé archive and is dated around 1929-1930, filmed in Berlin, not showing actual child labor practices of that time.

Historically, child labor, including chimney sweeping, was common in Europe, particularly in the 19th century. However, by the 1920s, laws in Germany prohibited children under the age of 10-13 from working in such roles. The tools in the footage appear miniature and outdated, suggesting it was more of a playful scene rather than a real job.

Additionally, chimney sweeps were seen as symbols of good luck in Germany, and it was common for children to dress up as them. The child in the footage was likely just having fun or posing for a photographer, rather than actually working.

Research led to identifying the boy as Horst Böhnke, and more details about his family were uncovered. The story continues to evolve as more information is discovered, but it's clear that the footage does not depict genuine child labor.

Elizabeth Holmes, the former CEO of Theranos, is currently in prison for fraud. Meanwhile, her partner, Billy Evans, has raised millions for a new biotech startup called Haemanthus, which aims to develop AI technology for medical testing. Holmes is advising Evans on this venture from prison, although her exact role is not clear.

Haemanthus, named after the Greek word for "blood flower," is in its early stages and is focused on using light detection technology, specifically Raman spectroscopy, to diagnose diseases like ALS and some cancers. The goal is to make this technology more affordable and accessible for patients, moving it out of research labs into commercial use.

Despite her fraud conviction and a decade-long ban from public company leadership, Holmes plans to return to the healthcare industry after her release and has been working on new inventions while incarcerated. The startup is still developing its product, which could involve testing biological materials like sweat or saliva.

A recent controversy has emerged about a 2017 study from a Microsoft-funded lab at Delft University, which explored using ultrathin "nanowires" as components in quantum computing. The study is under scrutiny after one of the authors admitted to "undisclosed data manipulations." This has led to calls for the paper's retraction from some authors who feel the corrections made were insufficient.

The research aimed to demonstrate how these nanowires could function as qubits, the basic units of quantum computers, which could revolutionize fields like chemistry and drug discovery. However, issues have plagued the field, including previous retractions of related papers for data irregularities.

Despite the concerns, Microsoft announced progress in developing a quantum chip with eight qubits made from these nanowires, claiming peer-reviewed support for their findings. The co-author of the 2017 paper, Vincent Mourik, raised alarms about selective data reporting, noting that only some of the tested nanowire data were included in the publication.

The lead author, Önder Gül, acknowledged he was aware of the data issues before publication but did not consider them significant. Other authors, including senior researcher Leo Kouwenhoven, denied any intentional wrongdoing and argued that the errors were addressed in later corrections. However, Mourik insists the corrections are inadequate, and some authors have distanced themselves from the study.

The journal Nature Communications has stated that they consider the matter closed and won't pursue a retraction despite the ongoing debate about the study's integrity.

The text is about a note from Mike Caro to Henri Bollinger, but it does not provide any specific details or content from the note.

Effect systems are currently a popular topic in programming research, but the author expresses skepticism about their practical benefits for software development. They believe these systems share a fundamental flaw with exceptions: they rely on dynamic scope, which can complicate understanding and maintaining code.

The author mentions that some newer effectful languages have moved towards using lexical or static scope, which addresses this concern. They explain that in traditional programming, exceptions allow control to be passed to handlers, but this can obscure when and where actions occur in the code, making maintenance difficult.

In the author's experience, using dynamic scope leads to confusion and unpredictability in large codebases. They advocate for a more structured approach, where functions explicitly receive the resources they need, often referred to as "dependency injection." This method helps clarify dependencies and improve code maintainability.

The author argues that effect systems might rely too heavily on inferred types, which can be less clear than explicitly passing parameters. They emphasize principles like simplicity and explicitness in programming, suggesting that clearer, parameter-based designs lead to more manageable and understandable code.

In conclusion, while effect systems are intriguing, the author believes that traditional methods focusing on clear parameter passing and explicit control flow are more effective for long-term software maintenance.

The Linux kernel development uses PGP for security, requiring maintainers to sign their pull requests. Konstantin Ryabitsev manages a repository of 602 valid keys, ensuring that there is a trust path from Linus Torvalds' key. Recently, issues arose because GnuPG 2.4.x stopped accepting SHA-1 signatures, which are outdated and insecure.

Currently, 6045 out of 7976 valid signatures in the repository use SHA-1. Linus Torvalds has signed 40 keys, mostly with SHA-1. If all SHA-1 signatures were removed, 485 public keys would lose their trust paths from Torvalds, affecting notable contributors like Andrew Morton and Greg Kroah-Hartman.

This would reduce the trusted kernel key set from 358 to 94. To address this, a keysigning session is being organized at Embedded Recipes 2025. Participants can send their public keys to a specified email by May 12, 2025, to join the session.

The article discusses how wealthy individuals significantly contribute to climate change, particularly through greenhouse gas emissions. Key findings include:

1. Disproportionate Contribution: The wealthiest 10% of the global population is responsible for about 65% of the warming from 1990 to 2020, with the top 1% contributing even more significantly, amplifying climate inequality.

The Trump administration is considering suspending habeas corpus, which is the legal right for individuals to challenge their detention in court. Stephen Miller, a top aide, stated that the Constitution permits this suspension during times of "rebellion or invasion." This discussion comes amid legal challenges related to the administration's immigration policies and the detention of foreign students.

Miller described habeas corpus as a "privilege" and claimed that Congress had limited the courts' authority over immigration cases. However, legal experts argue that only Congress has the power to suspend this right, not the president or his aides. Recent court rulings have led to the release of students detained for expressing dissenting views, while some judges have supported the administration's actions.

Habeas corpus has been suspended only a few times in U.S. history, and the authority to do so lies with Congress, not the president. Trump has not publicly mentioned the suspension but has indicated he would try to overcome legal challenges to his deportation efforts.

In April 1741, the British Royal Navy ship HMS Wager entered the treacherous Drake Passage, known as the "sailors' graveyard," during a violent storm. The ship, part of a secret squadron on a wartime mission against Spain, faced dire conditions, including severe weather and illness among the crew. Captain Dandy Kidd had died, and Lieutenant David Cheap took command, but the ship was in poor condition and lost contact with the rest of the squadron.

After weeks of struggling against the elements, Wager was wrecked on a rocky shore. The crew, now marooned on what they called Wager Island, faced starvation and harsh weather. They attempted to survive, scavenging for food and struggling with internal conflicts, including a mutiny led by John Bulkeley, the ship's gunner.

Eventually, a group of survivors built a schooner named Speedwell to escape. They sailed through dangerous waters, facing further challenges and loss of crew members. Ultimately, only thirty men reached Brazil, where they were rescued and returned to England after two years of hardship.

The narrative highlights themes of leadership, survival, and the harsh realities of naval life in the 18th century, culminating in a court-martial for the surviving officers. Despite their trials, many of the crew members went on to have notable careers, and the story of HMS Wager remains a cautionary tale of exploration and human endurance.
