In a recent blog post, Dylan Beattie reflects on the early hype surrounding Java when he was a computer science student from 1997 to 2000. Java was revolutionary at its launch in 1996, introducing important features like automatic garbage collection, threading, and exception handling, which were groundbreaking for high-level programming languages.

During this period, Java was seen as a solution to many software challenges. It was believed that Java applets would replace traditional desktop applications, and major companies like Corel were planning to create office software in Java. The idea of "write once, run anywhere" seemed promising, leading to the development of Network Computers that would run Java applications.

However, the reality was that Java faced stiff competition from other languages for desktop apps and games. As the tech landscape evolved, Java's initial excitement faded. By the mid-2000s, while its core features became commonplace, the ambitious projects like applets and Network Computers lost relevance.

Java transitioned from being a cutting-edge technology to a reliable tool for business applications. It became widely used for stable software, such as insurance and ticketing systems, which did not appeal to younger programmers looking for excitement.

Despite this decline in hype, Java has seen a resurgence, especially through its integration with Google's Android platform, achieving the "write once, run anywhere" vision through mobile devices. Today, while Java remains a solid programming language, it is no longer viewed as the groundbreaking technology it once was.

Summary: Async I/O on Linux and Durability

Jeremy Tregunna has been working on a complex database and recently tested a simple key-value database focusing on durability and performance. He began with a basic approach using a hash table and an append-only log, which was not as fast as desired.

To enhance speed, he explored io_uring on Linux, which enables truly asynchronous I/O operations. This new method allows multiple operations to be submitted at once, significantly increasing throughput. However, he encountered issues with data durability, as asynchronous I/O could lead to data loss if a system crash occurred before data was written to stable storage.

To address this, Tregunna proposed a dual write-ahead log (WAL) system:

1. Intent WAL: Records planned operations asynchronously.
2. Completion WAL: Records successful completions of those operations.

This design allows the system to quickly log intentions and later confirm completions, ensuring data consistency while improving performance. The implementation uses separate io_uring instances for each WAL to optimize performance and employs circular buffers to batch writes, reducing the number of disk operations.

During recovery, the system reads both logs to ensure only confirmed operations are applied, enhancing reliability. The dual WAL system does introduce some latency for individual operations, but it offers better performance when processing multiple operations simultaneously.

Overall, Tregunna's experiments demonstrated a tenfold increase in transaction throughput compared to synchronous methods, showing that modern hardware's parallel capabilities can be leveraged effectively with the right software architecture. His work encourages a reevaluation of traditional database designs that assume synchronous I/O is necessary for durability.

Summary of "Make Your Own Backup System – Part 1: Strategy Before Scripts"

In this article, Stefano Marinelli discusses the importance of creating a robust backup system for data protection. He emphasizes that many people underestimate backups, often viewing them as simple copies. This misconception can lead to significant data loss during emergencies.

Key points include:

1. Understanding Backups: Backups are more than just copying files; they must be consistent and restorable. Relying solely on cloud services can be risky, as users are ultimately responsible for their data protection.

2. Creating a Backup Plan: Before starting backups, consider questions like how much risk you can take, what data to protect, and how much downtime is acceptable. It's crucial to store backups away from the source machine to avoid losing both the original data and the backup.

3. Full Disk vs. Individual File Backups: Decide whether to back up entire disks or just specific files. Full disk backups are comprehensive but may require downtime and take up more space. Individual file backups are flexible and can be done without stopping the system, but they need careful management to ensure consistency.

4. Using Snapshots for Consistency: To avoid issues with "live" data changes during backup, use snapshots to create a stable version of the data at a specific point in time.

5. Backup Architecture: Choose between "push" (client-initiated) and "pull" (server-initiated) backup methods based on your security needs. A centralized, secure backup server is generally preferred.

6. Principles for a Good Backup System: Marinelli highlights the need for quick recovery, external storage, security, efficient space management, and minimal invasiveness in backup systems.

The article serves as an introduction to building a backup system, with future posts promised to delve into specific configurations and software techniques.

The GopherCon India talk titled "Go Faster: Optimizing Go Programs" focuses on improving the performance of programs written in the Go programming language. The speaker discusses various techniques and strategies to enhance speed and efficiency in Go applications. The key points include identifying performance bottlenecks, using profiling tools to analyze code, and implementing best practices for optimization. Overall, the talk aims to help developers write faster and more efficient Go programs.

The author discusses their experience developing a FAT driver in Rust, focusing on the challenges related to a feature called "specialization." Specialization allows more specific implementations of functions based on traits, but it is currently unstable in Rust due to safety and lifetime issues.

The author explains how, without specialization, they struggled to implement a FileSystem struct that could handle both read-only and read/write operations efficiently. They attempted several solutions, including using a macro and a generic enum, but faced complications.

Ultimately, they found a workaround using function pointers. This approach allows them to define different behaviors for loading sectors based on whether the storage is read-only or read/write, by passing a function pointer that syncs data when needed. While this solution works, the author acknowledges that it adds complexity and overhead.

They conclude that while their workaround is specific and not ideal, it highlights the importance of specialization in Rust, which, once stabilized, would provide a cleaner and more efficient way to handle such cases.

The Los Angeles city attorney’s office has sued Airbnb, claiming the platform allowed illegal price increases and hosted unverified listings after a fire disaster in January. The lawsuit targets over 2,000 rentals, alleging that Airbnb permitted price gouging during a state of emergency, where increases should be capped at 10%.

The city attorney, Hydee Feldstein Soto, argues that many listings had fake hosts and addresses, which misled renters. Airbnb countered these claims, stating they have provided substantial support to fire victims, including nearly $30 million in recovery efforts and free housing for thousands.

The lawsuit seeks fines of up to $7.5 million for the alleged price gouging and highlights concerns over Airbnb’s inadequate verification processes, which may expose users to risks like identity theft and fraud. Although Airbnb declared they would not allow price hikes beyond 10%, some fire victims reported difficulties with the support provided, claiming it was ineffective.

Eight babies have been born in the UK using a revolutionary technique that combines DNA from three people, aimed at preventing severe mitochondrial diseases. This method uses the egg and sperm from the parents and a donor egg from another woman, providing a small amount of healthy mitochondria to the child. Mitochondrial diseases, typically passed from mother to child, can cause serious health issues and are often fatal in infants.

The technique has been legal in the UK for a decade and is now showing promising results, with all children born free of these diseases. The Newcastle Fertility Centre has facilitated this process, which has brought hope to families at risk of these genetic conditions.

While the majority of the child's DNA comes from the parents, about 0.1% comes from the donor, which can be inherited by future generations. Parents who have undergone this procedure have expressed immense gratitude for the chance to have healthy children.

Research indicates that the method is safe, as most cases showed no detectable defective mitochondria. However, some children had a small percentage of defective mitochondria, which is still under investigation. This breakthrough could potentially change the lives of families affected by mitochondrial diseases, offering a way to prevent these conditions from being passed on to future generations.

The UK is the first country to legally permit this technique, which has sparked debates about genetic modification and its implications for future generations.

Summary of the Importance of Keeping Your Website Under 14kB

Having a website that is under 14kB in size can significantly improve loading times. A page of 14kB can load about 612 milliseconds faster than a 15kB page due to the TCP slow start algorithm, which affects how data is transmitted over the internet.

Key Concepts:

1. TCP and HTTP: Transmission Control Protocol (TCP) ensures reliable data transfer over the Internet. HTTP requests made by browsers use TCP to send and receive data packets.

2. TCP Slow Start: This algorithm determines how many data packets a server can send at once. It starts with a small amount (typically 10 packets) and increases the amount until it detects packet loss.

3. Why 14kB?: Most servers can send 10 packets of 1460 bytes each, totaling around 14kB. Keeping your website under this size allows for efficient data transfer and quicker loading.

4. Latency Issues: Latency, the time taken for data to travel, can cause significant delays. For example, satellite internet has high latency due to the distance data must travel, which can lead to long wait times for users.

5. Practical Tips: Aim to keep your website under 14kB, including compressed files. Focus on delivering essential content first, such as critical CSS and introductory text, to optimize user experience.

6. Exceptions: While the 14kB rule is a good guideline, some servers may allow for larger initial packet sizes. New protocols like HTTP/2 and HTTP/3 still recommend keeping within this limit.

In conclusion, minimizing your website size to under 14kB can lead to faster loading times and a better experience for users.

The text discusses the author's experience recording 5G NR signals in the n78 band (3.3 – 3.8 GHz) in Spain. Here are the key points:

1. Focus on n78 Band: The author is particularly interested in the n78 band due to its wide bandwidth (commonly 100 MHz) and its usage for 5G deployment in many European countries.

2. Recording Challenges: Recording in the n78 band is more complex and costly compared to traditional LTE bands due to the high bandwidth and the need for advanced SDR (Software Defined Radio) equipment.

3. Collaboration: The author teamed up with researchers from the University of Murcia, who provided access to high-end USRP equipment for the recordings.

4. Technical Issues: Initial attempts to use a USRP X410 were hindered by interference from nearby signals. They switched to a USRP N310, which successfully recorded data without interference.

5. Recording Data: The author faced challenges with recording IQ data at high rates to disk but eventually opted to record to a temporary filesystem (tmpfs) to avoid data loss, capturing datasets from three different 5G cells (Movistar, Orange, Vodafone).

6. Preliminary Findings: Early analysis of the recorded datasets indicates varying levels of cell utilization and different transmission patterns. The Movistar cell showed low to medium usage, while Orange was heavily utilized and Vodafone had low signals.

7. Datasets Available: The recorded datasets are published online for others to access and analyze.

Overall, the text highlights the technical challenges and solutions in capturing 5G signals, as well as initial observations from the recordings made in the n78 band.

Summary of "Trigon: Exploiting Coprocessors for Fun and Profit (Part 2)"

In this blog post, the author expands on the Trigon kernel exploit, which was initially released for A10 devices on iOS 13-15. The exploit is deterministic, meaning it is designed to succeed without failure. Since the first release, support has extended to A9(X) and A11 devices.

Key Points:

1. Original Exploit Strategy: The first version of Trigon finds the kernel base using KTRR limit registers, which protect kernel code. However, challenges arose with devices A9 and A11 due to differences in their architecture.

2. KTRR Background: KTRR (Kernel Text Read-only Region) is a security feature introduced with the A10 chip to prevent unauthorized access to kernel code. It operates at two levels: MMU KTRR (for CPU cores) and AMCC (Apple Memory Cache Controller for coprocessors).

3. IORVBAR: The author discovered that using IORVBAR (the IO Reset Vector Base Address Register) allows for better identification of the kernel base on A10 and A11 devices, as it points to physical addresses in the kernelcache.

4. Coprocessor Exploits: The focus shifts to exploiting the Always-On Processor (AOP). The author and a collaborator successfully accessed and modified its firmware to gain control over it, allowing arbitrary read/write operations.

5. AXI Remapping: The AOP uses a remapping technique, which allows it to access its firmware at physical address 0x0, while the actual firmware resides at a higher address.

6. Mapping DRAM: The exploit enables the AOP to read and write to normal DRAM, facilitating communication with the main processor and allowing for arbitrary memory access.

7. Improved Reading/Writing: The author and collaborator further developed the exploit to create a more sophisticated method for reading and writing data via the AOP.

8. Future Work: Although A7 and A8(X) devices remain unexploited due to architectural differences, the author notes that finding the kernel base is simpler on these devices, and future work may enable their support.

In conclusion, the post illustrates the complexities and innovations involved in exploiting coprocessors and discusses future possibilities for expanding the Trigon exploit. The author invites readers to reach out with questions and hints at ongoing research into further exploits.

The author, using the pseudonym Simurgh, has written a white paper inspired by the "Women, Life, Freedom" movement in Iran. The goal of the project is to help people communicate better and find common ground, which could reduce divisions among them.

The white paper proposes a structured deliberation system that can be implemented on existing platforms like Telegram. It is based on three main principles:

1. Absolute Anonymity: Protects the identities of participants.
2. Structured Process: Organizes discussions to separate valuable ideas from noise.
3. Meritocratic Promotion: Ensures the best ideas gain attention.

The paper also addresses potential risks such as state manipulation and security threats.

The author is seeking feedback from the Hacker News community, particularly regarding potential weaknesses in the design, suggestions for improvement, and insights from those experienced in building secure messaging systems. They are open to questions and discussions.

A recent study from the University of Colorado Boulder has raised concerns about erythritol, a common sugar substitute found in many low-carb and sugar-free products. The research suggests that even small amounts of erythritol can damage brain blood vessel cells, leading to increased risks of stroke due to factors like blood vessel constriction and clotting.

Erythritol is often favored for its low calorie content and minimal impact on insulin levels, making it popular among those managing weight and blood sugar. However, the study indicates that higher levels of erythritol in the bloodstream may correlate with a greater likelihood of heart attacks and strokes.

In laboratory tests, researchers found that erythritol-treated cells showed reduced production of nitric oxide (which helps blood vessels relax) and increased levels of endothelin-1 (which causes constriction). Additionally, these cells had a diminished ability to break down blood clots and produced more harmful free radicals.

The authors emphasize that their findings are based on laboratory studies and caution that more research is needed in humans. They recommend that consumers be mindful of erythritol in food labels, given the potential health risks indicated by the study.

A new bill in New York (S4091/A04873) aims to ban One-Person Train Operation (OPTO) on the subway, requiring a conductor to be on every train. Critics argue this move would hinder New York City's transit system, making it outdated compared to other cities that have adopted more modern practices, like fully automated trains. The bill could lead to reduced service and increased costs for riders, as it limits the Metropolitan Transportation Authority's (MTA) ability to operate efficiently and innovate.

Historically, New York's subway transitioned from needing two crew members to OPTO, which has been successfully implemented on several lines since the late 1990s. The bill is viewed as an attempt to protect specific jobs rather than enhance safety, as studies show OPTO does not compromise public safety. In fact, most major subway systems around the world have moved toward one-person or fully automated operations.

The legislation could inflate labor costs, making it financially challenging for the MTA, which may lead to fare hikes or reduced service improvements. Advocates argue that this bill would regress the subway system and call on Governor Hochul to veto it, suggesting that the focus should be on modernizing transit rather than adhering to outdated practices.

The idea is to create a map that shows real-time photos, currently using cat pictures. It's unclear how to develop it further, but it might be useful for someone. You can find the project on GitHub: worldsnap.

The article by Dave Rome emphasizes the importance of safety in all components of modern bicycles, arguing that every part can be critical to the safety of the rider. While many people focus on major components like handlebars and steerer tubes, Rome warns that other parts, such as tires and brakes, can also pose serious risks if they fail. He expresses concern about inexperienced individuals attempting repairs based on online tutorials, often without understanding the potential dangers.

Rome encourages cyclists, mechanics, and manufacturers to adopt a mindset that treats the entire bicycle as a collection of safety-critical parts. He highlights the complexities introduced by modern bike designs, which can make safety inspections more challenging. The article serves as a reminder to prioritize safety when maintaining and using bicycles, advising riders to seek experienced mechanics for proper inspections and repairs. Overall, it advocates for a more serious approach to bike safety, urging everyone involved in cycling to recognize the risks associated with component failures.

Summary:

The text discusses the evaluation of language models (LLMs) on challenging math problems from the International Mathematical Olympiad (IMO) 2025 as part of the MathArena project. The goal was to see if these models could achieve medal-level performance: bronze, silver, or gold.

Key points include:

• The top model, Gemini 2.5 Pro, scored 31% (13 points), which is below the 19 points needed for a bronze medal.
• Other models, like Grok-4 and DeepSeek-R1, performed poorly compared to previous benchmarks.
• OpenAI announced a gold medal achievement with a new model, but the proof's validation process was unclear.

Methodology:

• Four human judges with IMO-level expertise evaluated model responses immediately after the IMO problems were released.
• Five models were tested, each generating multiple responses for each problem, which were filtered using a best-of-n selection method to find the best answer.

Results:

• Gemini 2.5 Pro's score, though low, reflects the challenge of the problems.
• Other models did not reach significant scores, with Grok-4 notably failing to provide robust answers.

Qualitative Observations:

• Grok-4 often provided short answers without justification.
• Gemini 2.5 Pro showed improvement but still cited non-existent theorems.
• Models generally received partial credit for logical lapses, indicating potential for future improvement.
• The best-of-n selection process proved essential, as many generated responses were inadequate without it.

The study highlights the continued progress and challenges faced by LLMs in tackling complex mathematical tasks.

The U.S. government is considering changes to the H-1B visa program, which allows skilled foreign workers to work in the U.S. A recent filing suggests a shift from the current lottery system to one that selects applicants based on specific skills or criteria.

The H-1B program is popular among tech companies to fill positions they claim cannot be filled by American workers. However, it has faced criticism for lowering wages for U.S. workers and for enabling exploitation by outsourcing firms.

Advocates for U.S. workers argue that this system disadvantages American graduates, particularly in computer science. For instance, in 2023, more foreign workers were granted work permits in computer jobs than the number of U.S. graduates in that field. Critics say that H-1B visas often go to lower-paying positions, pushing American workers out of the job market.

Experts suggest that program flaws could be fixed with new regulations and policies to ensure better protections for American workers and to prioritize hiring them over foreign applicants. Proposed solutions include enforcing wage protections and requiring companies to actively recruit U.S. workers before hiring H-1B visa holders.

Summary of Zig's New Writer Update (July 17, 2025)

Zig is updating its IO namespace, which will eventually reintroduce async features. A key part of this update is the redesign of the Writer and Reader interfaces.

• New Writer Interface: The new Writer interface is called std.Io.Writer. All custom writers must implement a drain function, which takes an array of strings and a parameter called splat. This design is more complex than one might expect, as it incorporates built-in buffering.

• Buffering: When creating a Writer for a file, you must provide a buffer. You can use an empty buffer if no buffering is needed. This complexity explains the need for the drain method instead of a simpler write method.

• Implementation Example: The simplest implementation of drain writes the first element of the provided data array. The Writer will manage additional data writing automatically if there’s more data to process.

• File and Writer Relationship: When you create a Writer for a file, you actually get a File.Writer instance. To access the std.Io.Writer interface, you need to reference its interface field.

• Migration Changes: Some functions from previous versions have been replaced or removed, requiring users to adapt their code to use the new Writer methods. For example, std.fmt.formatIntBuf is now replaced with the printInt method of the Writer.

• Adaptation for Legacy Writers: Legacy writers must implement an adaptToNewApi method to convert to the new interface, allowing for easier integration with the updated system.

• Conclusion: While the update aims to improve the API, some users find the direct integration of buffering into the Writer interface less ideal than a more modular approach, such as separate buffered readers/writers.

Overall, while the changes are seen as an improvement, there is hope for a more unified solution in future updates.

The recent update on Section 174 is good news for the US tech industry, as it allows companies to deduct software development expenses, including salaries for developers, in the same tax year. This change reverses a previous regulation that required these costs to be spread out over several years, which had negatively impacted hiring and profitability, especially for small businesses.

Originally introduced in 2017 and affecting tax returns from 2022, Section 174 made it difficult for companies to manage their developer costs, potentially leading to fewer hires. However, the new legislation allows for retroactive deductions and the option to re-file taxes for the years 2022 to 2024, providing financial relief.

Despite these improvements, foreign developers’ costs are still required to be amortized over 15 years, which may lead US companies to hire less internationally. This change is expected to encourage more hiring within the US, while potentially reducing the number of developers hired abroad.

John Graham-Cumming’s blog post discusses his experience modifying a classic Casio F-91W watch using a new product from Oddly Specific Objects. This new version, called the Sensor Watch Pro, features an accelerometer and a custom LCD screen that allows for more complex text display. Unlike the previous version, this upgrade doesn’t require any soldering, making it easier to install.

To upgrade the watch, you simply replace the internal parts with those from the kit and connect a small piece from the original watch. Graham-Cumming customized the firmware on his watch to remove certain features he didn't want, like Imperial units and the 12-hour clock format.

He provides a detailed sequence of commands for building and uploading the new firmware to the watch, which involves using a micro USB connection and a web-based emulator to simulate the watch on a computer. Overall, the post highlights the fun and accessible nature of upgrading a classic watch with modern technology.

Intel is changing its approach to project approval, requiring all new products to achieve at least a 50% gross profit margin before they can move forward. This decision, announced by CEO Michelle Johnston Holthaus at a technology conference, aims to improve the company's financial performance. Intel's gross margins have dropped to around 31.67%, down from nearly 60% before the COVID-19 pandemic.

New CEO Lip-Bu Tan is focused on restoring shareholder value and may cancel unprofitable deals to help meet this margin goal. Despite the push for higher margins, there may be tension within the company as engineers and executives balance competitive product development with cost efficiency. Tan also plans to invest in top talent and foster a culture of innovation at Intel, even as the company prepares for potential layoffs of up to 20% of its workforce.

The text discusses how to achieve immutable logging on OpenBSD systems to comply with ISO 27001 standards, which require logs to be protected against tampering. Here are the key points:

1. ISO 27001 and Logging: ISO 27001 emphasizes the importance of protecting logs from unauthorized access and tampering. While it does not specify how to achieve this, the focus is on maintaining the integrity of logs.

2. OpenBSD Logging: OpenBSD has a straightforward logging system, but its default configuration can leave logs vulnerable to tampering, especially if an attacker gains root access.

3. Using chflags for Immutability: OpenBSD's chflags command can set two important flags:

   • sappnd (append-only) for active logs that need to grow.
   • schg (immutable) for archived logs that must not change.

4. Setup Steps:

   • Disable Automatic Log Rotation: Modify the cron job that rotates logs to prevent interference with the immutable flags.
   • Create an Archive Directory: Store immutable archived logs in a dedicated space.
   • Set Flags on Logs: Apply the sappnd flag to active logs and the schg flag to archived logs.
   • Automate with a Script: Create a script to manage log rotation and restore flags during system boot, ensuring logs remain immutable.

5. Conclusion: This setup ensures that even root cannot modify logs after they are written, thus providing the forensic integrity required by ISO 27001 without needing additional software or network dependencies.

The author encourages readers to explore these features in OpenBSD and other BSD systems for enhanced log security.

Autoregressive language models generate text one token at a time, which slows down their performance, especially when the text direction is clear. This work presents a new framework that allows these models to predict multiple future tokens at once, improving speed and efficiency. Key innovations include:

1. A method to predict several future tokens from a single starting point.
2. A technique that retains the original model's capabilities while enabling multi-token predictions.
3. A simple module that ensures smooth and coherent text generation from the predicted tokens.
4. Additional training methods to improve the accuracy and consistency of the generated tokens.
5. A strategy that allows for rapid token expansion while keeping the text quality high.

The new approach significantly speeds up the generation process—making tasks like coding and math nearly five times faster, and general chat tasks about 2.5 times faster—without sacrificing quality.

Customers are increasingly using Postgres and ClickHouse together, where Postgres handles transactions and ClickHouse focuses on analytics. To integrate these databases, Change Data Capture (CDC) is commonly used, which tracks changes in Postgres and replicates them to ClickHouse for real-time analytics. You can implement this integration through tools like PeerDB or ClickPipes in ClickHouse Cloud.

This blog details how Postgres CDC to ClickHouse functions and shares best practices for data modeling and query optimization. Key topics include deduplication strategies, custom ordering keys, optimizing JOINs, and using materialized views.

A practical example uses a subset of the StackOverflow dataset, illustrating how data is replicated from Postgres to ClickHouse and highlighting the use of ClickPipes for efficient data handling. The replication process involves using Postgres Logical Decoding, which sends changes to ClickHouse in a readable format.

To ensure that query results are consistent between Postgres and ClickHouse, the blog recommends using the FINAL keyword to deduplicate data in ClickHouse queries. Additionally, strategies like creating views or using materialized views can help maintain consistency without altering original queries.

Optimizing JOINs is also discussed, with ClickHouse offering improved performance for these queries compared to Postgres. Denormalization techniques are suggested to enhance query speed further.

Overall, the blog provides a comprehensive guide on effectively leveraging Postgres with ClickHouse to enhance analytical capabilities and improve performance. It encourages users to explore ClickHouse Cloud with promotional credits for new users.

Summary:

Loris Cro discusses the distinction between asynchrony and concurrency in programming, emphasizing that they are not the same.

• Definitions:
  • Asynchrony: Tasks can run out of order and still be correct.
  • Concurrency: A system can progress multiple tasks simultaneously, through either parallelism or task switching.
  • Parallelism: Multiple tasks are executed at the same physical time.

Cro provides examples to illustrate these concepts. For instance, saving two files can occur in any order (asynchrony), but a client-server connection requires tasks to overlap (concurrency).

He notes that a lack of understanding of these terms has led to programming challenges, such as libraries duplicating effort and forcing users to abandon synchronous code. In Zig programming language, asynchrony does not automatically mean concurrency; code using io.async can run in a single-threaded mode, allowing synchronous and asynchronous code to work together effectively.

Cro concludes by encouraging a clearer understanding of these concepts to improve coding practices and mentions a live demonstration of Zig's async I/O redesign.

Summary: The Rise of the Grifter Equilibrium in Advertising

Advertising typically serves two important roles: it provides information to help consumers and signals the quality of products. However, the internet has changed how advertising works, making it easier to search for products but also weakening the ability of ads to signal quality.

Key points include:

1. Frictions in Advertising:

   • Disposable Brand Identities: New brands can easily start up with minimal costs, making it easy to hide bad reputations.
   • Cost-Per-Acquisition (CPA) Pricing: Advertisers can now pay only when sales happen, allowing low-quality sellers to advertise without significant upfront investment.
   • Light Returns: Easy return policies mean sellers face only small penalties for poor-quality goods, allowing many mediocre products to remain on the market.
   • Compressed Ratings: Product ratings cluster around similar scores, making it hard for consumers to differentiate quality.
   • Heuristic Shopping: Without clear signals, consumers rely on price as an indicator of quality, prompting sellers to list similar products at different prices.

2. Grifter Equilibrium: These issues create a market where low-quality sellers can thrive alongside high-quality ones, leading to a situation where advertising does not effectively signal quality.

3. Market Dynamics: For both high and low-quality sellers to advertise, they must make a profit. If only low-quality sellers can advertise profitably, it leads to adverse selection.

4. Proposed Solutions: To restore effective signaling in advertising, suggestions include:

   • Using persistent manufacturer IDs to tie reputation to the producer.
   • Implementing return-adjusted CPA fees.
   • Introducing escrowed advertising bonds that are forfeited if quality metrics are not met.
   • Enhancing detection of low-quality relaunches.

5. Market Resilience: Despite these challenges, the marketplace doesn’t collapse because:

   • Return policies allow consumers to avoid the worst products.
   • Low production costs enable low-quality sellers to remain profitable.
   • Consumers often accept some risk in quality for convenience and low prices.

Overall, the advertising landscape has shifted, creating a challenging environment for quality signaling, but also providing ways for the market to remain functional.

The author decided to build a Retro Chip Tester Pro after considering it for a while and learning about it from a friend. They faced challenges in purchasing it since the creator, Stephan Slabihoud, does not ship to Portugal, so they had to arrange for a friend in the Netherlands to bring it to them.

After receiving the kit, which included printed circuit boards (PCBs) and instructions, the author successfully assembled the tester using clear documentation. They encountered a minor issue with a display but quickly resolved it.

Once assembled, the tester worked perfectly, successfully testing a 4164 DRAM chip and reading a C64 BASIC ROM. The Retro Chip Tester Pro can also program chips and has various adapters for different tasks. Although it is not open-source, it comes with extensive documentation and has an active community for support.

The author highlights the differences between this tester and other products, noting its versatility as a ROM dumper and programmer, which will aid in troubleshooting and repairing retro computers. Additionally, the author received a bonus item, a replica logic tester from the 1970s, which they plan to discuss in a future post.

The text presents a new finding about Ramsey numbers, specifically r(ℓ, Cℓ), for any constant C greater than 1 and large values of ℓ. It shows that there is a positive number ε, depending on C, such that the Ramsey number is at least ((p_C^{-1/2} + ε)^\ell). Here, p_C is a specific value between 0 and 1/2 that relates to C. This new result offers a significant improvement over the earlier lower bound established by Erdős in 1947.
