This article discusses an interesting project where the author experimented with hosting a web server on a disposable vape device. Initially, the author collected these vapes for their batteries but discovered they contained a capable microcontroller, specifically the PUYA C642F15, which is based on the ARM Cortex-M0 architecture.

The author explains how they set up a web server using a protocol called SLIP (Serial Line Internet Protocol) to connect the vape to a network. They used a small TCP/IP stack called uIP to run a minimal HTTP server. Although the initial performance was poor, with slow response times, the author optimized the server by implementing a ring buffer, which significantly improved its speed.

After optimization, pings dropped to 20 milliseconds, and web pages loaded in about 160 milliseconds, making the setup surprisingly efficient given the limited resources of the device. The author notes that while the storage capacity is small, it is sufficient to host simple content and even run server-side code in C.

The article concludes by highlighting the potential of using such microcontrollers for fun and innovative projects, despite their limitations.

Eric, the CTO of Trigger.dev, introduces their platform designed for developers to build and manage AI agents and workflows. It's open-source and provides tools for creating, deploying, monitoring, and debugging these agents. Users can self-host or use Trigger.dev's cloud service, which handles scaling.

The platform was launched in 2023 to help developers run asynchronous tasks in TypeScript. Initially, it focused on orchestrating code but evolved to allow developers to run their code reliably, addressing challenges like serverless timeouts and task dependencies.

A key innovation is their use of a technology that lets them pause and resume code on different servers, improving efficiency. This has led to increased adoption, especially for AI-related tasks.

Users can start with the Trigger.dev cloud, self-hosting, or refer to the documentation for more details. Upcoming features include improved self-hosting options and new execution methods. They welcome feedback from the community.

The article discusses the impact of "programming deflation," a phenomenon where advancements in technology, particularly AI, are making software development cheaper and easier. This raises two conflicting economic theories: one suggests fewer programmers will be needed as machines replace human labor, while the other predicts that lower costs will increase demand for software, leading to more programmers.

Key points include:

1. Deflation in Programming: Unlike traditional economic deflation, which is harmful, programming deflation is driven by productivity gains and leads to lower costs for creating software.

2. Paradoxes: As coding becomes cheaper, there is a temptation to delay projects for even cheaper tools, but the low cost also encourages experimentation. There will be a greater divide between poorly written and high-quality code.

3. Skills Shift: Writing code may become a basic skill, akin to typing, while valuable skills will shift towards understanding systems and making sense of the abundance of cheap software.

4. Innovation Acceleration: Cheaper tools can accelerate innovation, leading to more individuals and businesses becoming involved in software development.

5. Focus on Understanding: In this new landscape, skills like judgment, integration, and system thinking will be crucial, regardless of the number of programmers.

6. Adaptation: Organizations and individuals should focus on developing these higher-level skills to thrive in the changing environment rather than trying to predict the future of programming.

In summary, programming deflation is reshaping the software industry, and adapting to these changes by enhancing understanding and judgment will be key to success.

Zstandard's long range mode, introduced in 2017, enhances compression for large files, especially useful for genome sequences. Initially, it had performance issues but has since improved. The feature is designed to help bridge the gap between fast, general compressors and slower, specialized DNA compressors.

A well-known dataset of 661,405 bacterial genomes showed that while basic Zstandard compresses quickly, it achieves a low compression ratio (CR) of 3. However, using the long range feature, the compression ratio improved significantly when cosmetic newlines were removed from the data.

Removing these newlines increased the CR to 11 and reduced the file size to 232GiB with only a slight increase in compression time. Further adjustments, like using a larger window size, improved the CR to 31, resulting in an 80GiB file, although this requires matching settings during decompression.

Overall, using the long range mode with proper data formatting can yield results close to specialized methods while maintaining faster processing times.

To determine how large a solar battery is needed for a home to be completely self-sufficient in electricity, the author provides insights based on their experience with solar panels in suburban London. Their solar panels generate about 3,800 kWh per year, which matches their annual electricity usage. However, they cannot use all the generated power in summer and must buy electricity in winter.

Key points include:

1. Energy Production and Consumption: The solar energy generated peaks during the day, while household electricity usage spikes in the evening when cooking. This mismatch requires storing excess energy generated during the day for use at night or in winter.

2. Battery Size Calculation: On a day when the home used 9.7 kWh and generated 19.6 kWh, the author concluded they would need a 13 kWh battery to store enough energy for evening use, not just the excess of 9.9 kWh.

3. Annual Storage Requirement: Analyzing one year of data, the author estimated that a battery with 1,068 kWh (or 1 MegaWatt-hour) of storage would be needed to hoard all excess summer energy for winter use.

4. Practical Considerations: The author acknowledges that such a large battery may not be practical or cost-effective, considering factors like increased energy use from electric vehicles and the environmental impact of producing large batteries.

5. Future Possibilities: While grid-scale batteries are effective, the cost of a domestic MegaWatt-hour battery could be prohibitively high (between £100k and £500k). However, battery prices are decreasing, and advancements in technology could make it feasible for homes to have such batteries in the future.

In conclusion, while it's theoretically possible for homes to achieve solar self-sufficiency with large batteries, practical and economic factors currently limit this potential.

The article discusses interesting concepts in recreational mathematics, particularly focusing on different geometric metrics and their implications for the value of π.

• The author introduces topological concepts, explaining that topologists study shapes based on continuous transformations, disregarding traditional measurements.
• In standard geometry, the distance between two points can be calculated, but non-Euclidean spaces have different metrics, such as the taxicab metric, where distance is based on the sum of horizontal and vertical movements.
• The article explains how circles are defined differently in various metrics, including taxicab and Chebyshev distances.
• A key finding is that the value of π changes depending on the metric used. For instance, in taxicab geometry, π is calculated to be 4, while traditional Euclidean π is approximately 3.14.
• The author concludes that the “minimal” value of π occurs in standard Euclidean space, and intriguing results arise when exploring metrics with exponents less than 1, leading to increasingly larger values of π.

The piece encourages readers to think about geometry in a new light and highlights the unexpected variations of π in different mathematical frameworks.

The author is developing an Open Source Ecommerce framework for Angular called Daffodil, which allows users to connect to different ecommerce platforms. After seven years of work, Daffodil is now ready for feedback, especially from frontend developers with ecommerce experience.

For those unfamiliar with JavaScript, there is a demo available online. Angular developers can easily integrate Daffodil into their projects using a simple command.

The author aims to address two main issues:

1. Learning Curve: They dislike having to learn different ecommerce platforms, as each has its own way of doing things. They wish for a standard interface for these platforms, similar to how hardware drivers work in operating systems.
2. Simplicity: They want to avoid complex setups like Docker or Kubernetes when building ecommerce UIs. The goal is to start with just the core frontend tools.

Currently, Daffodil supports platforms like Magento, MageOS, and Adobe Commerce, with partial support for Shopify and Medusa. The author acknowledges that performance could be improved with GraphQL but prefers to keep initial development simple. They welcome suggestions for additional drivers and platforms, but cannot guarantee implementation.

On September 15, 2025, a new private CSS property from Apple called -apple-visual-effect was noted, which can create Liquid Glass effects in web content. This feature was highlighted during WWDC 2025 and represents a major change in iOS design since the shift away from skeuomorphic styles.

The -apple-visual-effect property allows developers to implement Liquid Glass effects, but it only works within native iOS applications and requires a specific setting in WKWebView that is private and not available for public use. Despite this limitation, the property could enhance the appearance of webviews in apps if Apple chooses to use it, suggesting that seamless webviews may exist in iOS without users realizing it.

The article emphasizes that while this property is interesting, it cannot be widely used outside of Apple's environment, leaving its impact limited to internal applications.

1. Library Purpose: The library simplifies string formatting by allowing users to create formatted strings using a format string and parameters, similar to printf, but with a more modern and safer approach.

2. Basic Usage:

   • A format buffer is defined, and the fmt::format function is used to insert parameters into a format string.
   • Curly braces {} are used as placeholders for parameters, and double braces {{ are used to include a literal brace.

3. Buffer Management: If the buffer is too small, the function writes as much as it can and indicates how many characters were needed, allowing for buffer resizing.

4. Functionality: The library includes functions to handle different data types and formats them into the buffer. It avoids complex type specifiers for ease of use and readability.

5. Implementation Details:

   • A String_Buffer structure holds the buffer and its capacity.
   • A write function ensures safe writing to the buffer.
   • The next_hole function parses the format string to find placeholders.

6. Design Choices:

   • The library avoids using printf due to its verbosity and risk of error.
   • It emphasizes simplicity and efficiency without heavy template usage.

7. Ergonomic Enhancements: Additional utility functions, like Static_String, provide an easy interface for formatting strings without manual buffer management.

Summary of "Beyond Orthogonality: How Language Models Pack Billions of Concepts into 12,000 Dimensions"

In this article, Nicholas Yoder explores how language models like GPT-3 manage to represent millions of concepts within a limited space of 12,288 dimensions. The key insight is that while a traditional N-dimensional space can only hold N completely orthogonal vectors, allowing for "quasi-orthogonal" relationships (vectors at angles between 85-95 degrees) significantly increases capacity.

Yoder discusses an experiment inspired by Grant Sanderson's video on transformer models, where an attempt to fit 10,000 vectors into a 100-dimensional space showed that maintaining near-orthogonal relationships was possible. However, he encountered issues with the loss function used for optimization, leading to a suboptimal configuration where many vectors were nearly parallel rather than evenly spaced. By adjusting the loss function, he was able to achieve better results, leading to insights about the limits of vector packing in high-dimensional spaces.

The article also explains the Johnson-Lindenstrauss lemma, which allows projecting high-dimensional points into lower dimensions while preserving distances. This lemma is vital for applications like e-commerce, where it enables efficient computations on customer preferences represented in high-dimensional spaces.

Through experimental investigations, Yoder reveals that the capacity for distinct concepts in these embedding spaces is much greater than previously thought, even allowing for representations that exceed the number of atoms in the observable universe. The findings have significant implications for dimensionality reduction and the design of embedding spaces in language models, indicating that current dimensions can effectively represent complex human knowledge.

In conclusion, the exploration of high-dimensional geometry not only enhances understanding of machine learning models but also highlights the importance of collaboration in advancing mathematical research.

The author describes their experience searching for "AI chat" apps in the Mac App Store, comparing it to a market filled with counterfeit goods. They found many apps that look similar to the official ChatGPT app from OpenAI, which is not actually available in the store, as it can only be downloaded from the OpenAI website. The search results featured numerous apps with names combining variations of "AI," "Chat," and "Bot," often in confusing formats. The author humorously compares this situation to trying to find genuine products in a store filled with knock-offs, highlighting the overwhelming number of lookalike apps and quirky names.

The AirPods Pro 3 have received a positive review, highlighting that they have improved even further compared to previous versions. The review praises their enhanced features and overall performance, making them some of the best wireless earbuds available.

The article titled "Death to Typeclasses" discusses a shift from traditional type classes in Haskell towards a module system called Backpack. The author uses the metaphor of "Death" to represent transformation and the end of reliance on type classes.

Key points include:

1. Concept of Functors: The article introduces functors as essential components in functional programming, explaining how they can be defined and used in a new way through module signatures rather than type classes.

2. Backpack Modules: The author advocates for using the Backpack module system, which allows merging various types and signatures into a module, simplifying the structure and making it more flexible.

3. Implementation Details: The text provides examples of how to implement functors and their instances, particularly using the Maybe type. It discusses how to manage dependencies and build configurations in Cabal (the Haskell package manager).

4. Business Logic and Effects: The article outlines a simple business logic example that interacts with file systems, demonstrating how to manage effects while maintaining a clean separation of concerns.

5. Error Handling and Compilation: The author notes that while Backpack can lead to clearer error messages, it can also introduce new types of errors in the build process, emphasizing the need for careful management of modules and dependencies.

6. Final Thoughts: The post concludes with a call for further exploration of the Backpack system, suggesting it could be a more effective way to handle effects in Haskell programming compared to traditional type classes.

Overall, the article presents a provocative view on evolving Haskell programming practices, encouraging readers to consider alternative methods for structuring code.

Summary: Creating a VGA Signal in Hubris

The author experimented with a ST Nucleo-H753ZI evaluation board using Hubris, an embedded operating system. Initially, they wanted to create a VGA signal using an old VGA monitor. They discovered that they could wire the VGA pins to the board's GPIOs to generate the signal.

Key Steps in the Project:

1. Bypassing the Sys Task: The author decided to manage GPIO pins directly instead of using the system task, which typically handles GPIO operations. They aimed to reduce overhead and control the pins more efficiently.

2. Basic Setup: Their initial goal was to display a single color by getting the vertical and horizontal sync signals correct, along with keeping the green pin high.

3. Register Mapping: The chip's peripherals are controlled through memory-mapped registers. The author used a Peripheral Access Crate (PAC) for simplified access to these registers, defining necessary memory regions in configuration files.

4. Using PWM for Blinking LEDs: They tested pulse-width modulation (PWM) to blink an LED, which would later help generate VGA sync signals.

5. Establishing H-Sync and V-Sync Timers: The author set up timers to create the correct timing for horizontal and vertical sync signals based on VGA timing specifications, adjusting parameters to fit a resolution of 800x600.

6. Color Signal Issues: Initial attempts to display a solid green image failed, likely due to how monitors interpret voltage signals.

7. Using DMA with DAC: The author attempted to use a Digital-to-Analog Converter (DAC) along with Direct Memory Access (DMA) to manage signal output without overloading the CPU.

8. Memory and Buffer Challenges: They faced issues with memory regions and buffer sizes when trying to display a 2D image. Eventually, they reintroduced the sys task to better manage memory regions.

The project is ongoing, and the author hopes to further develop their VGA signal generation and explore new ideas for a framebuffer.

The author worked on a project using the AWS SDK for JavaScript and noticed that one of its dependencies had a version number of v3.888.0. This led to a curiosity about which package in the npm registry has the highest version number.

To find out, the author explored the npm API and discovered there are over 3.6 million packages. Using the npm replication API, they fetched the package IDs and their versions. The process took several hours, involving fetching metadata for each package and analyzing the version numbers.

The initial "winner" for the largest version was a package with a version of 1,000,000,000,000,000,000.0, which was dismissed as not a legitimate entry. Instead, the author refined the search to focus on packages that follow semantic versioning standards.

Ultimately, after filtering out packages with inconsistencies in versioning, the real winner was found to be a package named "all-the-package-names" with a version number of 2.0.2401, which is the highest valid version that adheres to semantic versioning rules.

In summary, the author’s exploration revealed interesting insights about the npm registry, versioning practices, and the challenges of determining valid package versions.

The article discusses the frustration of handling chargebacks for SaaS products at Everhour, which uses Stripe for billing. Despite efforts to prevent disputes—such as clear communication about charges, easy cancellation options, and sending invoices—some customers still file chargebacks instead of requesting refunds.

Key points include:

1. Chargeback Challenges: Even if a company wins a chargeback dispute, the mere act of filing it negatively impacts their account and incurs fees, which seems unfair, especially for small payments.

2. Customer Behavior: The author is puzzled as to why some customers choose to dispute charges rather than simply asking for a refund.

3. Bank Bias: The article emphasizes that banks often side with cardholders in disputes, disregarding the merchant's evidence and terms. This makes it difficult for companies to defend themselves.

4. Examples: The author shares two stories: one where a chargeback was filed despite clear evidence showing the customer had canceled after the charge, and another where a long-term customer disputed a charge due to a payment card issue, which was resolved after communication.

5. Call for Discussion: The author questions the fairness of the chargeback process and asks the community for insights into why banks don’t require proof from customers when filing disputes.

Overall, the article highlights the complexities and frustrations of managing chargebacks in the SaaS industry and raises questions about the fairness of the current system.

The text discusses the Culture novels, which are often seen as utopian representations of a future with positive AI superintelligence. However, the author provides a counter-perspective, suggesting that the Culture may actually have dystopian elements.

Key points include:

1. Perspective of Culture Members: The novels mainly present the views of Culture citizens, who fully embrace their society's ideology. This makes it hard to assess the true nature of their society without questioning their beliefs.

2. Homogeneity of Citizens: The Culture's population is described as strangely uniform, lacking diversity in behavior and personality. This suggests that the Culture may manipulate its citizens through propaganda or genetic engineering, leading to controlled outcomes.

3. Minds and Control: The AI Minds, meant to be benevolent, show signs of misalignment and do not fully adhere to the values of Culture. They maintain control through strength and surveillance rather than ethical superiority.

4. Cultural Stasis: The Culture seems trapped in a state of stagnation, unwilling to evolve or fully engage with the universe outside its borders, which raises questions about its true nature as a utopia.

5. Special Contact: The author argues that the Culture's interactions with other civilizations are superficial and serve as propaganda rather than genuine engagement.

In conclusion, the Culture may appear utopian at first glance, but it is suggested that its citizens are more like pets in a controlled environment, deprived of true autonomy and higher aspirations like justice and self-determination. The allure of wealth and technology masks deeper issues within their society.

Cory Doctorow discusses how science fiction's true power lies not in inventing new technologies, but in imagining different social uses for those technologies. He emphasizes that the impact of a gadget depends on who it serves and how it is used. For example, while AI can be used effectively for personal tasks like transcribing audio, it can also be misused in industries to replace numerous workers while putting the burden of errors on a single individual.

Doctorow contrasts two experiences with AI: his own positive use of an open-source transcription tool and a freelancer's negative experience with a major publication relying on AI to produce erroneous content. He introduces the terms "centaur" (a person aided by technology) and "reverse-centaur" (a person working at a machine's pace and bearing the consequences of its mistakes) to highlight the difference in how technology can be employed.

He critiques the narrative pushed by tech companies that AI must be used to cut jobs and exploit workers, arguing that society can choose better ways to arrange technology. Ultimately, Doctorow encourages questioning these social arrangements and seeking alternatives that empower rather than exploit people.

In her essay "In the Land of Living Skies," Suzannah Showler reflects on her relationship with darkness while living in Regina, Saskatchewan. She describes how her early-morning routines, where she embraced the dark hours, led her to a personal exploration of solitude and creativity. Despite her appreciation for the expansive night sky, she rarely ventured out at night to experience it fully.

Showler discusses the growing problem of light pollution, highlighting that artificial light is increasing significantly worldwide, which prevents many people, especially children, from seeing natural night skies. This loss of darkness has ecological consequences, affecting wildlife and human health, and it also diminishes our cultural connection to the stars, which have historically helped us find meaning and direction.

She shares her journey to Grasslands National Park, a designated dark-sky site, seeking a deeper encounter with true darkness. Despite facing challenges like rain and cloudy skies during her visit, she ultimately experiences the beauty of a star-filled sky, realizing the significance of darkness in contrast to the ever-present light of modern life.

Showler emphasizes that darkness is not just absence but a source of mystery and clarity. She reflects on how society’s fear of the dark has led to an overreliance on artificial lighting, which can obscure our understanding of the natural world. The essay invites readers to reconsider their relationship with the night and the importance of preserving darkness in a world increasingly dominated by artificial light.

Summary: OCSP Service Ended

On August 6, 2025, Let’s Encrypt officially shut down its Online Certificate Status Protocol (OCSP) service. This decision was announced in December of the previous year. All certificates that included OCSP URLs have now expired, and Let’s Encrypt will now provide revocation information only through Certificate Revocation Lists (CRLs).

The main reason for ending OCSP support is due to privacy concerns. When users check a site's certificate via OCSP, the Certificate Authority (CA) can see the IP address of the visitor and the site they are visiting, which poses a privacy risk. In contrast, CRLs do not have this issue.

Additionally, simplifying their operations is important for Let’s Encrypt to maintain compliance and efficiency. Operating the OCSP service required significant resources, which can now be redirected to other needs. Previously, they handled around 340 billion OCSP requests monthly, and they thank Akamai for their support in providing CDN services for the last ten years.

Summary of Page Object Concept

The page object model is a design pattern used in web testing to simplify and stabilize tests by encapsulating the details of a web page's structure. Instead of directly manipulating HTML elements, a page object provides a higher-level API that allows tests to interact with the UI like a human would.

Key points include:

1. Encapsulation: Page objects hide the complexity of the underlying HTML. They provide methods that reflect user interactions, such as accessing text fields or clicking buttons, without exposing the HTML structure.

2. Hierarchy of Objects: Rather than creating a page object for every single web page, it's better to create them for significant components of a page (like lists or headers) to keep the structure intuitive and user-focused.

3. Page Navigation: When navigating to a new page, the current page object can return a new page object representing the next page, simplifying the flow of tests.

4. Assertions: There is debate on whether page objects should include assertion logic. The author prefers not to include assertions in page objects, arguing that they should only provide data for tests rather than mixing responsibilities.

5. Concurrency Handling: Page objects can also manage issues related to asynchronous operations and threading, making it easier to deal with complex UI interactions.

6. Testing Frameworks: It's common to layer testing DSLs (Domain Specific Languages) over page objects for clearer and more maintainable test scripts.

7. Encapsulation Benefits: This design principle allows for easier updates to UI logic without affecting other parts of the system, making the test code cleaner and more focused on testing intent.

Overall, the page object model enhances test maintainability by separating UI details from test logic, leading to clearer and more robust test scripts.

Robert F. Kennedy Jr., as the U.S. Secretary of Health and Human Services, is pushing an anti-vaccine agenda, claiming that COVID-19 mRNA vaccines are linked to the deaths of 25 children. He is considering limiting access to these vaccines to individuals aged 75 and older, rather than 65 and older. This information is reportedly based on unverified reports from the Vaccine Adverse Event Reporting System (VAERS), which has been criticized for its reliability.

Despite these claims, federal health experts maintain that COVID-19 vaccines are safe, with extensive monitoring showing only a low risk of heart-related side effects. In fact, 25 children died from COVID-19 itself, not the vaccine, and many were unvaccinated.

Kennedy has a history of opposing mRNA vaccines and has taken actions to dismantle support for their development. He recently canceled significant funding for mRNA vaccine research and replaced members of a key vaccine advisory panel with individuals who share his views. His upcoming meeting of this panel may lead to further restrictions on vaccine access.

This shift has drawn widespread criticism from medical organizations, lawmakers, and even some members of Congress, who argue that Kennedy's actions could harm public health. Some have called for him to resign, and there are concerns about the legitimacy of the upcoming advisory panel meeting.

Proxmox, an open-source virtualization platform, is testing a new tool called "Datacenter Manager" to better compete with VMware.

• Participants categorized in the highest RNT quartiles (Q3 and Q4) scored significantly lower on cognitive assessments compared to those in the lowest quartile (Q1).

Implications:

• The findings suggest that addressing RNT could be a way to help prevent cognitive decline in older adults.
• The study calls for further research, particularly long-term studies, to better understand the mechanisms linking RNT and cognitive function.

Conclusion: This research highlights the negative impact of repetitive negative thinking on cognitive health in older adults, emphasizing the need for mental health assessments and interventions to improve cognitive outcomes.

Summary:

In this article, the author discusses the challenges faced while getting coreboot to run on the Gigabyte MZ33-AR1 motherboard with the new AMD Turin CPU. They encountered issues due to insufficient firmware blobs provided by AMD, which led to a workaround involving injecting coreboot into the vendor firmware.

Key points include:

1. AMD PSP Firmware Structure: Modern x86 CPUs have co-processors like the AMD Platform Security Processor (PSP), which runs its own firmware stored alongside the BIOS. The author explains how the Embedded Firmware Structure (EFS) helps locate and configure these firmware components during startup.

2. Analysis and Improvements: The author improved the tools used to analyze the firmware, allowing them to identify differences between the coreboot and vendor images that could prevent the system from booting.

3. Identifying Firmware Differences: Key differences in configuration settings, such as SPI speeds and eSPI settings, were identified, which are crucial for the system's operation.

4. Integrating Missing Blobs: The author extracted necessary firmware blobs from the vendor image and integrated them into coreboot to create a bootable image.

5. Using Public Blobs: Attempts to use publicly available blobs were unsuccessful due to differences in key signatures. The author tested the latest AMD PSP blobs from the Turin PI package, which worked and allowed the CPU to boot.

6. Future Steps: While public blobs are currently inadequate, preparations are in place to use the correct blobs when they become available. The coreboot tools have been updated for better functionality.

The author concludes that while challenges remain in porting coreboot to this platform, progress continues, and they encourage readers to stay updated on future developments.

The text discusses the author's approach to reading, emphasizing that they read to forget rather than to remember everything. They view themselves as a constantly evolving system that updates their beliefs, rather than a storage device for information. The author criticizes the habit of highlighting large portions of text, believing it's impractical given the abundance of reading material and limited time.

Instead, they aim to gain two main things from reading: a subtle shift in their thinking and a few key pieces of information for future use. They enjoy reading texts that inspire new ideas or actions, and if a non-fiction work doesn't provoke thought, they find it unworthy of their time. Ultimately, the author believes that excessive note-taking can lead to clutter and that it's impossible to keep track of everything read.

The author reviews four Samsung 870 QVO 4TB SATA SSDs after four years of use, primarily in a home server and backup role. They originally chose these SSDs to avoid the noise from traditional hard drives and to benefit from their faster speeds and lower power consumption.

Key points include:

• The drives, manufactured in 2021, have shown good performance with minimal issues, mainly related to a Linux kernel problem.
• During heavy writing tasks, the drives maintain speeds of 140-170 MB/s, significantly better than cheaper SATA SSDs, which can drop to as low as 30 MB/s.
• One drive reported 4 bad blocks, despite having the fewest power-on hours.
• The SSDs have a reported lifespan of about 94% with over 170 TB of data written, far below Samsung’s endurance limit of 1440 TBW.
• Prices have decreased from around 400 EUR to about 270 EUR each, but not as much as expected. Alternative 4TB SSDs are available from 190-200 EUR, though their performance under sustained writes is uncertain.

Overall, the Samsung 870 QVO SSDs remain a solid choice even after four years of use.

The author, who identifies as a "slow thinker," reflects on their slow processing speed and how it affects various aspects of life, including social interactions, academics, and career. They initially felt disadvantaged compared to quick-witted individuals, particularly in fast-paced environments like competitive sports and math classes. However, they have come to realize that slow processing can also have advantages.

Instead of trying to speed up their thinking, the author suggests embracing their natural pace. They observe that both quick-witted and slow thinkers can achieve similar levels of success, indicating that processing speed may not be as crucial as previously thought. The author believes that slow thinkers often develop compensatory strategies, such as patience and careful planning, which can be valuable in fields like science where thoroughness is essential.

They emphasize the importance of adapting to one's thinking style, finding that writing and coding suit their slower processing better than verbal communication. Overall, the author concludes that leaning into their slow thinking has led to personal growth and a newfound sense of confidence.

The IBM Personal Computer (PC), launched on August 12, 1981, set the standard for personal computing but was never truly an "IBM" product in spirit. While designed and manufactured by IBM, the PC relied heavily on components from other companies, like Intel for the CPU and Microsoft for the operating system. This reliance on external suppliers led to a lack of control over the product and enabled competitors, like Compaq, to emerge quickly, offering better value.

IBM's attempts to maintain its market dominance with proprietary products, such as the PS/2, ultimately failed. Despite the PC's initial success, IBM's management showed little enthusiasm for selling PCs compared to other products, viewing them as lower priority. This cultural disconnect, along with the open nature of the PC that invited competition, contributed to IBM losing its grip on the market. By 2005, IBM sold its PC business to Lenovo, which distanced itself from the IBM brand soon after.

In summary, the IBM PC's initial success was undermined by a lack of unique identity, poor management focus, and an inability to control its own market, leading to IBM's decline in the PC sector.

Summary: The Unreasonable Effectiveness of Modern Sort Algorithms

This text discusses the effectiveness of specialized sorting algorithms compared to general-purpose hybrid sort algorithms, focusing on scenarios where data has very few distinct values. The author, Lukas Bergdoll, who is involved in the development of specific sort algorithms used in Rust, conducts benchmarks to analyze performance.

Key Points:

1. Scenario: The sorting task involves data with a type that can hold many distinct values (u64), but only four unique values are actually present. This allows programmers to use specialized sorting methods.

2. Benchmark Setup: Tests were run on a powerful computer with specific Rust compiler settings, using a benchmark suite to assess various sorting methods.

3. Domain Optimized Algorithms:

   • BTree: Uses a data structure to count occurrences of values, resulting in a median sorting speed of ~145 million elements per second for small inputs.
   • Hash: Leverages hash maps for counting and sorting, generally performing faster than BTree but requires an additional sorting step.
   • Match: A custom approach that handles exactly four known values, leading to improved performance, especially on small datasets.
   • Branchless: An optimization that avoids branch mispredictions by evaluating all conditions, significantly improving throughput.

4. Perfect Hash Function: This method allows direct mapping of known values to their positions for sorting, achieving high throughput (~1.7 billion elements per second) but is sensitive to changes in input data.

5. Robustness: The specialized algorithms may falter if data characteristics change, leading to inefficiencies or incorrect outputs.

6. Comparison with Generic Algorithms: The Rust standard library's generic sort function can handle sorting without specific knowledge about the input, achieving about 660 million elements per second, but it has higher memory access costs.

7. Conclusion: While domain-specific algorithms can outperform general ones with careful design and understanding of CPU architecture, high-quality generic implementations are still very effective. Programmers should weigh the benefits of custom solutions against the risks of implementing their own sorting methods.

The author emphasizes the importance of thorough benchmarking and understanding the underlying hardware when optimizing sorting algorithms.

3. Composer Autoloading: This tool simplifies class loading, eliminating the need for manual file includes. It uses a specific structure to group plugin-related classes.

4. Creating Classes: The article outlines how to structure functionality into reusable classes, enhancing clarity and maintainability.

5. Enforcing Coding Standards: The author discusses setting up automated tools for linting and formatting JavaScript, CSS, and PHP. This ensures consistent code quality and improves collaboration.

6. Global Commands: Commands are provided to streamline the linting process across different file types.

7. Conclusion: By incorporating these practices—namespacing, autoloading, and coding standards—developers can build more scalable, maintainable, and collaborative WordPress projects.

The article also offers practical steps, code examples, and links to additional resources to help developers implement these strategies effectively.

The author expresses a strong interest in the programming language Gleam, describing it as a blend of features they appreciate from other languages like Rust, Erlang, and Go. They appreciate Rust for its type system but find its learning curve steep. The author highlights their desire for a language with algebraic data types, which Gleam offers. They also admire Gleam's simplicity, having only 22 reserved keywords, making it easy to learn.

Key features of Gleam include:

• Sum Types and Pattern Matching: Gleam allows expressive data types and pattern matching similar to Rust and Erlang, enabling clear handling of different data scenarios.
• Concurrency Model: As it compiles to Erlang, Gleam benefits from Erlang's actor model, which simplifies concurrent programming.
• Functional Programming Constructs: Gleam uses recursion instead of traditional loops, which can be daunting but is manageable with practice. It also includes a powerful use construct that simplifies error handling and chaining function calls.

The author acknowledges some concerns, such as the potential complexity of the BEAM runtime and the learning curve associated with immutable data types. They believe Gleam won't completely replace Rust but will be a valuable tool for specific use cases, especially those involving concurrency.

Overall, the author is excited about Gleam and recommends exploring it further, particularly through instructional videos by Isaac Harris-Holt.

Summary of Gentoo Council AI Policy

On April 14, 2024, the Gentoo Council established a policy stating that contributions to Gentoo using Natural Language Processing (NLP) AI tools are not allowed. This decision can be re-evaluated if a safe AI tool is proposed that does not raise copyright, ethical, or quality issues.

Key Points:

1. Copyright Concerns: Current copyright laws regarding AI-generated content are unclear and could lead to violations, risking Gentoo’s copyright status and copyleft licensing.

2. Quality Concerns: AI tools can generate content that sounds good but lacks real substance, potentially lowering the quality of Gentoo projects. They may also create extra work for developers and users to identify errors.

3. Ethical Concerns: The rise of AI has led to serious ethical issues, including:

   • Copyright violations in training AI models.
   • High energy and water usage.
   • Negative impacts on jobs and service quality.
   • Increased spam and scams due to AI capabilities.

The policy does allow for the addition of AI-related software packages that are developed by others.

A recent discovery by the James Webb Space Telescope (JWST) has identified a massive black hole, named QSO1, weighing 50 million times more than our sun, existing in the early universe without a surrounding galaxy. This finding challenges existing theories about how galaxies and black holes formed, which traditionally suggested that black holes emerged only after galaxies were established.

Astrophysicist Roberto Maiolino, part of the research team, emphasized the significance of this discovery, suggesting it might indicate a new class of "naked" black holes that formed independently from galaxies. The discovery raises questions about how such a large black hole could have existed so early, with some scientists proposing that it might have originated from conditions present during the Big Bang.

QSO1 was detected among several other similar objects, referred to as "little red dots," which have sparked debate among astronomers regarding their nature. The research team used the JWST to analyze the light from QSO1, confirming its mass and that it orbits gas, indicating it is indeed a black hole. The gas surrounding it is primarily hydrogen, suggesting that QSO1 formed before many stars had developed.

Overall, this discovery opens up new avenues for understanding the formation of black holes and galaxies in the universe's early years, indicating that black holes may have been some of the first large structures to form in the cosmos.

Summary of SpikingBrain

SpikingBrain Overview
SpikingBrain is a large model inspired by brain mechanisms that combines advanced techniques like efficient attention, MoE (Mixture of Experts) modules, and spike encoding. It can be trained continuously with less than 2% of the typical data while maintaining performance comparable to leading open-source models. It also adapts to non-NVIDIA clusters for effective large-scale training, achieving over 100 times speed improvement for long sequences.

Project Structure
The repository includes the SpikingBrain-7B model in various formats for easy deployment and experimentation:

• hf_7B_model/: HuggingFace version
• run_model/: Model usage examples
• vllm_hymeta/: vLLM plugins for NVIDIA GPU support
• W8ASpike/: Quantized version for efficient inference

vLLM-HyMeta
This is a plugin that enhances the vLLM inference framework for better performance on NVIDIA GPUs. It allows for easier integration of new hardware backends and reduces maintenance costs.

Installation and Usage
To set up SpikingBrain, clone the repository and install the necessary packages. For serving models, simple command-line instructions are provided.

W8ASpike
This is a quantized version aimed at reducing inference costs. It uses pseudo-spiking methods, which approximate spike-like signals rather than employing true spiking that requires specialized hardware.
