Instead of accepting a deal to return most of the funds in exchange for a reward and a chance to work as an ethical hacker, he went into hiding, believing his actions were justified under the “Code is Law” philosophy.

After two years, he allegedly executed a similar scheme, stealing about $48.4 million from another platform, KyberSwap. He now faces five serious criminal charges, including wire fraud and money laundering, and could face decades in prison if convicted. U.S. authorities are trying to locate him, as he remains a fugitive.

Medjedovic excelled academically, finishing his bachelor’s and master’s degrees in mathematics at the University of Waterloo at a young age. His background includes success in coding contests and a family comfortable with technology. However, his actions raised significant legal and ethical questions, as many argue that exploiting code vulnerabilities is illegal and constitutes market manipulation.

Despite being sought for his alleged crimes, Medjedovic communicated with reporters, claiming to work as a white hat hacker while evading capture. In late 2023, he was briefly detained in Europe but released without extradition to the U.S. His legal troubles continue, with ongoing lawsuits from individuals and companies affected by his actions, as well as his hope that changing political climates might lessen scrutiny of cryptocurrency-related cases.

The text discusses how to effectively handle data fetching from an API in a React application, particularly when dealing with components like a "LikeButton."

Key Points:

1. API Data Structure: The API returns data related to likes on a post, including total likes, whether the user has liked it, and friends who liked it. This data can be structured in JSON format.

2. Component Data Flow: Instead of fetching data from the API in a parent component and passing it down as props, the text suggests a novel approach where the API directly returns the component (e.g., LikeButton) with the necessary data filled in. This method challenges traditional component-API relationships.

3. Models vs. ViewModels: The text differentiates between "Models" (raw data shape) and "ViewModels" (data shaped for UI consumption). For instance, a Like Model might contain timestamps and user IDs, while a LikeButton ViewModel would focus on total likes and friend interactions.

4. REST API Design Challenges: The article highlights the complexities of designing REST APIs. It discusses how the shape of ViewModels is driven by UI requirements, leading to difficulties in evolving the API as the UI changes. This often results in a mismatched structure between what the front-end needs and how the API is organized.

5. Evolving API Needs: As UI designs change, APIs need to adapt, which can lead to complications like over-fetching or under-fetching data, and the challenge of maintaining a clean API structure.

In summary, the text presents an innovative perspective on integrating React components with API data, while also addressing the tensions and challenges in REST API design related to evolving UI needs.

Zig's LinkedList API has been updated significantly in version 0.14. The new implementation of SinglyLinkedList no longer uses generics and instead employs an intrusive linked list design, which embeds the linked list node within the user data. This approach typically results in better performance and fewer memory allocations.

The new structure for SinglyLinkedList is simpler and does not directly reference user data. Here is a brief outline of how it works:

1. You create a linked list and allocate memory for user data, which includes a node for the linked list.
2. You can prepend nodes to the list, linking them together.
3. To traverse the list, you access the nodes and can retrieve user data using a new built-in function called @fieldParentPtr. This function allows you to get back to the original user instance from the node.

While the new API has advantages, the inclusion of @fieldParentPtr may seem complicated for what is essentially a simple linked list. However, it is a useful tool that can help solve various problems in Zig programming.

Summary of Target Triples and Cross-Compiling

Cross-compiling means creating a program for a different machine than the one you're using. Modern compilers are mostly cross-compilers, allowing developers to build applications for various platforms, like creating an iPhone app without using an iPhone.

A "target triple" is a string that describes the platform a compiler can generate code for, typically in the format: <machine>-<vendor>-<os>. For example, x86_64-unknown-linux-gnu specifies a 64-bit Intel architecture for Linux without a specific vendor.

1. Components of a Target Triple:

   • Machine: Identifies the architecture (e.g., x86_64).
   • Vendor: Often irrelevant, mainly for organizing related operating systems (e.g., unknown or apple).
   • OS: Specifies the operating system, influencing executable formats (e.g., Linux, Windows).
   • ABI: Sometimes included, indicating the application binary interface, which affects how programs interact with system libraries.

2. GCC vs. LLVM:

   • GCC (GNU Compiler Collection) historically required separate compilers for each target, making cross-compiling cumbersome.
   • LLVM (Low-Level Virtual Machine) has become the standard, using a unified compiler binary with flags to specify the target.

3. Naming Conventions:

   • Target naming lacks strict standards, leading to inconsistencies. LLVM is the most referenced source for accepted names, and many compilers now follow its conventions.
   • Common architectures include various versions of x86, ARM, MIPS, and more, each with multiple aliases.

4. Vendor and OS Examples:

   • Vendors often relate to the organization behind an OS, like Apple or Intel.
   • Some systems use "unknown" for cases where the vendor is unimportant, and others detail specific OS versions or environments.

5. ABI Importance:

   • The ABI dictates how the compiler generates code, affecting features like threading and linking. It's crucial for ensuring compatibility with various libraries.

6. WebAssembly Targets:

   • WebAssembly uses a different approach, often simplifying the target triple to two components, with specific naming conventions.

7. Creating New Triples:

   • If inventing your own target triples, keep them simple and avoid unnecessary complexity. Stick to established names to avoid confusion.

In summary, target triples play a vital role in cross-compiling by providing a standardized format to identify the target platform for compiled code.

Recent advancements in language models (LLMs) have enhanced their reasoning abilities by incorporating a detailed thinking process during output generation. However, this paper questions the necessity of such explicit thinking. Researchers tested a model called DeepSeek-R1-Distill-Qwen and found that a simpler approach, called NoThinking, can be surprisingly effective. By avoiding the thinking process, NoThinking performed better than Thinking on various challenging reasoning tasks, particularly when resources were limited.

For example, on one task, NoThinking scored 51.3 compared to 28.9 with Thinking, using the same number of tokens. The performance of NoThinking improves as more outputs are generated and combined. The researchers used specific methods to combine these outputs, which often outperformed traditional Thinking methods while maintaining similar response times. Overall, this study suggests that lengthy thinking processes may not be necessary and offers a new way to achieve strong reasoning performance efficiently.

Researchers have discovered ancient skeletons in Libya that date back about 7,000 years from a time when the Sahara Desert was a lush, green environment. They analyzed the DNA of two well-preserved women, revealing a unique human lineage that was genetically distinct from both nearby sub-Saharan populations and ancient groups in Europe and the Near East. This suggests that these people were isolated despite having a nomadic lifestyle involving animal herding.

Previously, scientists thought the green Sahara was a migration route for humans, but the findings indicate that cultural exchange, rather than large-scale migration, spread practices like pastoralism in the region. The two women’s DNA showed they diverged from sub-Saharan ancestors around 50,000 years ago and remained genetically isolated for thousands of years.

While this research provides valuable insights into human ancestry, scientists note that more studies are needed to understand the broader population of the green Sahara, as the sample size is small. Overall, the work contributes to understanding Africa’s complex population history and highlights lineages that are not easily found in modern genomes.

Overall, the text illustrates the evolution of supernova observation and emphasizes the rapid advancements in astronomy that allow for the monitoring of these explosive events.

Summary: Designing a Low-Cost High-Performance Vector Network Analyzer (VNA)

A Vector Network Analyzer (VNA) is a device that measures the electrical characteristics of circuits at high frequencies, specifically their scattering parameters (S-parameters). These measurements are crucial for designing electronics that operate in the GHz range. Traditional VNAs are expensive, especially those that operate at higher frequencies.

Past Projects: The author previously built two homemade VNAs, the first being a basic model (10 MHz to 6 GHz) in 2016, which had significant measurement inaccuracies. An improved version in 2017 offered better performance but still felt limiting. The author seeks a VNA that can operate above 10 GHz with better accuracy and isolation.

Current Options: While there are inexpensive commercial VNAs like the nanoVNA (limited to 1-4 GHz) and the LibreVNA (100 kHz to 6 GHz), they do not meet the author's needs. Higher-end models from companies like Copper Mountain or Keysight are too costly, prompting the author to consider building a new VNA.

VNA Design: The new design will include:

• Four Receiver Architecture: This allows for more accurate measurements and advanced calibration techniques.
• Signal Sources: Utilizing modern phase-locked loop (PLL) chips simplifies signal generation and improves isolation.
• Directional Couplers: Essential for measuring incident and reflected waves, these need to maintain good performance across the desired frequency range.
• Receiver and ADC: Choosing cost-effective components that still meet performance needs was crucial; the selected ADC (AD9238) has a good dynamic range for the application.

In 2024, Google suspended 39.2 million advertiser accounts, a significant increase from the previous year, as part of its efforts to combat ad fraud. The company used advanced technology, including large language models (LLMs), to identify and suspend fraudulent accounts before they could run ads.

Last year, Google made over 50 updates to enhance safety across its platforms. A dedicated team of over 100 experts worked to analyze and counter deepfake ad scams. This resulted in the suspension of more than 700,000 accounts and a significant reduction in reports of deepfake ads.

In the U.S., Google suspended 39.2 million accounts and removed 1.8 billion ads, with violations mainly related to ad network abuse and trademark misuse. India had the second-highest number of account suspensions, totaling 2.9 million.

Google also verified new election advertisers and removed millions of election ads, though these made up a small portion of overall ads. The company claimed that its efforts led to fewer harmful ads reaching the platform.

While large suspensions can raise fairness concerns, Google provides an appeal process to ensure appropriate actions are taken. The company is working on improving communication and transparency with advertisers regarding its policies and decisions.

Summary of "Evelyn Waugh’s Decadent Redemption"

Henry Oliver discusses Evelyn Waugh's novel Brideshead Revisited, written in 1945, which has sparked both admiration and criticism. The story follows Charles Ryder, a disillusioned soldier, as he reflects on his youth and his friendship with Sebastian Flyte, an aristocrat whose family is deeply Catholic. Charles, an atheist, grapples with the family's faith and Sebastian's struggles with alcoholism, leading to his eventual estrangement from their world.

Waugh wrote the novel during World War II, seeking to capture a bygone era of beauty and privilege. Critics of the time condemned its ornate style and its Catholic themes, perceiving Waugh's shift from a satirical writer to a religious one as a betrayal. Despite the disdain from literary circles, Brideshead resonated with a broader audience, offering a nostalgic escape to a more elegant past.

The novel's second half centers on Charles's journey back to faith, particularly through his relationship with Julia Flyte, Sebastian's sister. As he confronts his materialistic views, he begins to understand the deeper meanings of beauty and goodness that Sebastian embodied. The story culminates in Charles's spiritual awakening, revealing Waugh's message about redemption and grace.

Oliver argues that the novel's rich prose and themes of faith are essential to its greatness, and that dismissing its religious elements undermines the story's emotional power. Ultimately, Waugh illustrates that beauty, love, and even sin can lead to God's grace, affirming the possibility of redemption in a flawed world.

In April 2025, a YouTuber asked viewers to de-pixelate part of a video where sensitive information was blurred. He offered a $50 reward for anyone who could reveal the hidden content. Surprisingly, three people succeeded in less than a day using different methods.

One user shared their process on GitHub, which involved two techniques. The first used TensorFlow for a brute-force approach to extract pixel data, resulting in a somewhat clear image, while the second method employed GIMP for better image selection, yielding a fully readable result.

The author noted that blurring or pixelating video can be ineffective at hiding information, especially with moving images. Technologies like AI have made it easier to reverse-engineer these effects. To better protect sensitive data in the future, the author plans to use solid color masks instead of pixelation or blurring.

The main takeaway is that if you want to keep information private, it's best not to post it online at all.

Summary: First Live Footage of a Baby Colossal Squid

On April 15, 2025, it was announced that the first confirmed live footage of a colossal squid, specifically a juvenile measuring 30 centimeters (about one foot), has been captured in its natural habitat. This historic event took place during an expedition by the Schmidt Ocean Institute's research vessel, Falkor (too), near the South Sandwich Islands. The squid was filmed at a depth of 600 meters (1968 feet) using a remotely operated vehicle called SuBastian.

This year marks the 100th anniversary of the colossal squid's discovery, which can grow up to 7 meters (23 feet) and weigh as much as 500 kilograms (1100 lbs). Prior to this, sightings were limited to remains found in the stomachs of predators. The footage not only highlights the colossal squid but also includes the first confirmed footage of another species, the glacial glass squid, filmed during a previous expedition near Antarctica.

The discoveries were part of an Ocean Census expedition aimed at exploring new marine life, involving collaboration among various international research organizations. Scientists expressed excitement about these findings, emphasizing the vast unknowns in the ocean and the importance of continued exploration.

Summary:

A significant vulnerability in AI systems, known as "prompt injection," allows malicious commands to be hidden within user inputs, potentially leading to harmful actions. Researchers have struggled to find a reliable solution, but Google DeepMind has introduced a new method called CaMeL (Capabilities for Machine Learning), which aims to address this issue.

CaMeL operates by treating AI models as untrusted components within a secure framework, creating clear boundaries between safe user commands and harmful content. It utilizes established security principles, like Control Flow Integrity and Information Flow Control, to safeguard AI interactions.

The system employs two language models: a "privileged LLM" that generates action plans based on user commands and a "quarantined LLM" that processes potentially untrusted data but cannot execute actions. This separation prevents malicious text from influencing decisions made by the AI.

CaMeL has shown promise in testing against various adversarial attacks, but it is not a complete solution. Users must specify and maintain security policies, which can complicate the user experience. The hope is that future improvements will enhance usability while maintaining security, ultimately leading to safer AI assistants.

The iOS app for email will be available soon, allowing users to manage their emails while on the move.

In a recent article, Sandor Dargo discusses his experience with code optimization, particularly focusing on the use of raw loops versus modern C++ features like ranges. After joining a new project, he noticed opportunities to improve code, especially regarding a loop that transformed data.

He initially used a traditional loop to create a response from a widget containing data. Later, he refactored the code to use std::ranges::transform, which is available in C++20, to enhance readability by eliminating raw loops and unnecessary vector modifications.

Dargo then analyzed the performance of both implementations. While the ranges version was more readable, he found that it could be slightly slower than the raw loop version. However, he emphasized the importance of measuring performance in context, as the differences may be negligible in many scenarios.

He concluded that while using ranges and algorithms improves code readability, performance should not always be the main concern unless the code becomes a bottleneck. Developers should choose the version that strikes the right balance between clarity and efficiency for their specific needs.

This project showcases the ability to create a portable version of a popular text editor while navigating various technical challenges and system dependencies.

Summary of Wright’s Law and Learning Curves in Technology

Wright’s Law states that as the cumulative production of a technology increases, its price decreases at a consistent rate. This phenomenon is illustrated through solar technology, where the price of solar panels has fallen by 20% each time global cumulative capacity doubles over the past four decades.

The learning curve, shown in a chart, indicates this relationship between the number of solar panels produced and their decreasing price. This consistent price decline is due to "economies of scale," where increased production leads to lower costs. Unlike Moore’s Law, which focuses on time, Wright’s Law emphasizes experience gained from cumulative production.

The learning rate for solar panels is 20%, meaning that every time cumulative capacity doubles, the price drops significantly. This relationship creates a cycle: as production increases, prices fall, leading to greater demand and even more production.

Research has shown that increased production experience drives down prices, not the other way around. This was demonstrated during World War II, where demand for military technology led to increased production and lower prices.

Understanding which technologies follow a learning curve is crucial for predicting their future. Technologies that do, like solar panels and computers, tend to become widely used as their costs decrease. This contrasts with many other technologies, where prices do not decline significantly with increased production.

In conclusion, recognizing technologies that follow Wright’s Law can help us accurately forecast advancements and their impact on society, avoiding past misjudgments about their potential.

Effective reasoning is essential for solving difficult math problems. Recent advancements in large language models (LLMs) have improved performance by using long chain-of-thought reasoning. However, traditional transformer models struggle with context length due to their complex memory and computation requirements.

This paper presents a new model called M1, which combines linear RNN architecture with the Mamba framework for more efficient memory use. M1 improves upon existing models through a process of distillation and reinforcement learning (RL) training.

Tests on the AIME and MATH benchmarks show that M1 surpasses older linear RNN models and performs as well as top distilled reasoning models, like Deepseek R1, at a similar scale. Additionally, M1 processes information over three times faster than comparable transformer models. This speed allows it to achieve better accuracy with a fixed generation time by using self-consistency voting.

In summary, the Mamba reasoning model offers a more effective way to enhance reasoning capabilities while improving efficiency in generating results.
