To quickly copy SQLite databases between computers, especially large ones, you can use a method that avoids transferring heavy indexes. Here's a simplified breakdown of the process:

1. Identify the Problem: As SQLite databases grow, copying them directly becomes slow and unreliable due to large indexes that duplicate data.

2. Use SQLite Dump Command: Instead of copying the database directly, you can create a text dump of the database using the command:

   $ sqlite3 my_database.db .dump > my_database.db.txt
   

   This text file is often much smaller than the original database because it reduces indexes to simple instructions rather than duplicating data.

3. Compress the Dump: To save even more space, you can compress the text dump:

   $ sqlite3 my_database.db .dump | gzip -c > my_database.db.txt.gz
   

4. Copy the Compressed File: Use rsync to transfer the compressed file to your local machine:

   rsync --progress username@server:my_remote_database.db.txt.gz my_local_database.db.txt.gz
   

5. Reconstruct the Database: After downloading, decompress and reconstruct the database:

   gunzip my_local_database.db.txt.gz
   cat my_local_database.db.txt | sqlite3 my_local_database.db
   

6. Benefits: This method ensures a stable copy without the risk of corruption from ongoing updates during transfer. It can significantly reduce download times, as demonstrated by one example where a 3.4 GB database was reduced to just 240 MB when compressed.

This approach can save time and improve reliability when managing large SQLite databases.

A judge in Northern California, Yvonne Gonzalez Rogers, has ruled that Apple’s actions regarding its app store are anti-competitive and has made a criminal contempt referral against an Apple executive for lying under oath. This decision stems from a long-running antitrust case initiated by Epic Games in 2020. Although Epic lost some federal claims, it succeeded in a state claim, leading to a court order that Apple must allow app developers to communicate with users and sell apps outside the App Store without fees.

Despite this ruling, Apple attempted to evade compliance by introducing new fees and misleading the court. The judge condemned these actions, specifically citing Apple Vice-President Alex Roman for lying under oath, and referred the case for potential criminal charges. Apple has stated it will comply but plans to appeal the decision.

In another development, a proposal by Republican leader Jim Jordan to weaken antitrust laws was withdrawn after significant pushback from various groups, including both Democrats and some conservative factions. This proposal aimed to merge the FTC's competition authority with the Department of Justice, which could have harmed ongoing antitrust cases.

On May 1, 2025, an author expressed frustration over the misuse of the term "vibe coding" by two publishers and three authors. Vibe coding, coined by Andrej Karpathy, refers to a relaxed approach to coding where the coder relies heavily on AI tools without focusing on the code itself. However, the books titled "Vibe Coding" by Gene Kim and Steve Yegge, and "Vibe Coding: The Future of Programming" by Addie Osmani misinterpret this definition, discussing how to integrate AI tools into professional software development instead.

The author believes there is a real need for a book that accurately covers vibe coding for non-developers—helping them use these tools to automate tasks without needing to learn programming. This misuse of the term by established authors and publishers not only misrepresents the concept but also misses an opportunity to address a significant audience that could benefit from vibe coding techniques.

Summary of RSAC Article:

At the RSA Conference, experts discussed the growing issue of North Korean infiltrators posing as tech workers in Western companies to steal intellectual property and introduce malware. Adam Meyers from CrowdStrike shared that these infiltrators create fake online profiles and use advanced techniques, including AI, to secure jobs in major companies. A key interview question that can expose them is about Kim Jong Un's weight, which often causes them to withdraw.

Once hired, these workers are effective because they collaborate in teams to deliver high-quality work, making it hard for companies to suspect them. Their goal is twofold: earn a salary and steal sensitive information gradually. The FBI recommends conducting coding tests during interviews to verify the candidate's identity and performance.

However, North Korean operatives are adapting, using laptop farms in the U.S. to disguise their locations and even utilizing deepfake technology to mislead recruiters. Experts stress the importance of vigilance in hiring practices, including having local meetings and being cautious with remote employees to prevent these infiltrations.

Summary:

Ladybird is a new browser engine from the SerenityOS project, currently in pre-alpha phase. The focus is on its JavaScript engine, LibJS, which has an interpreter but no compilation tiers yet. LibJS employs modern optimizations and rigorous checks to prevent vulnerabilities like integer overflows.

For testing, the author used Fuzzilli, a tool for fuzzing JavaScript interpreters. After running it for about 10 days, 10 unique crashes were found, including common bugs and several interesting ones, like a regex parser bug and an integer overflow in TypedArray. The most notable bug was a use-after-free (UAF) vulnerability in the interpreter's argument buffer.

The UAF occurs when a function object is used as a constructor and can lead to accessing freed memory. This vulnerability was demonstrated with a JavaScript example that exploits the argument buffer being freed before use. The solution involves modifying when the prototype is accessed to avoid the UAF.

Further exploitation methods include leaking memory addresses and creating fake objects to gain arbitrary read/write capabilities, eventually leading to control over the browser's execution flow. This process involves manipulating memory structures to overwrite return pointers and execute arbitrary code.

The document includes technical details about the bugs, the fuzzing process, and the exploitation techniques used, culminating in a demonstration of a successful exploit.

Robert F. Kennedy Jr., the current U.S. Health and Human Services Secretary, has publicly rejected the established germ theory of disease, which states that diseases are caused by microscopic germs. Instead, he supports a controversial idea known as terrain theory, which suggests that diseases result from imbalances in the body, like malnutrition or toxins. In his book criticizing Anthony Fauci, Kennedy misrepresents germ theory as a tool used by the pharmaceutical industry to sell medications, while promoting the idea of strengthening the immune system through nutrition and environmental health.

Kennedy's beliefs have raised concerns about his influence on public health policies. His denial of germ theory underpins his opposition to vaccines and mainstream medicine, leading to a chaotic environment within federal health agencies and cuts to essential health services. Experts worry that his views, which he holds strongly, could endanger public health, especially as the U.S. faces a significant measles outbreak.

Despite the outbreak, Kennedy has focused on less urgent issues, such as removing artificial food dyes from the food supply, rather than addressing vaccination efforts. This disconnect highlights the potential dangers of his leadership and the impact of his beliefs on public health initiatives.

Summary of Agent Reinforcement Trainer (ART)

ART is an open-source library designed to enhance the performance of large language models (LLMs) using reinforcement learning (RL) with minimal code changes. It employs the GRPO algorithm, allowing models to learn from their experiences while integrating seamlessly into existing codebases.

Recently, there was a blackout in the Iberian Peninsula caused by a phenomenon called "induced atmospheric vibration." This occurred due to extreme temperature changes in Spain, which led to unusual oscillations in high-voltage power lines. These oscillations caused synchronization failures in the electrical systems, resulting in widespread disturbances.

Many users are trying to understand what "induced atmospheric vibration" is, as it's not widely documented. Some experts believe it relates to corona discharges, which occur when the air around high-voltage lines becomes ionized, especially in hot, dry conditions. This can create unexpected electrical behaviors that disrupt the power grid.

The incident highlights how sensitive power systems are to environmental changes. When unexpected conditions lead to imbalances, it can trigger automatic safety protocols that disconnect sections of the grid, causing cascading failures. As the climate changes, these issues may become more frequent unless better models and safeguards are developed.

Measuring progress in science is essential, but benchmarks can become distorted. Chatbot Arena is a leading leaderboard for ranking AI systems, but we found systematic issues that create an unfair environment. Some providers can test multiple AI versions privately before making them public, allowing them to choose the best scores and skew results. For example, Meta tested 27 different AI models before releasing Llama-4.

Additionally, proprietary models receive more testing and fewer removals from the leaderboard compared to open-source models, leading to unequal access to data. Companies like Google and OpenAI have a significantly higher share of the data compared to many open-weight models. Access to more data can greatly improve performance on the leaderboard.

These factors lead to AI models being tailored to the specific conditions of the Arena rather than reflecting their overall quality. We recommend changes to the Chatbot Arena's evaluation process to make benchmarking fairer and more transparent.

A few years ago, I joined a study called the Citizen Science Sourdough Project, which aimed to collect and analyze sourdough starter samples from everyday people. Recently, I received the results for my sourdough starter, named Stinkie.

Here are the key findings from my report:

1. Twins: Stinkie has identical counterparts in Switzerland, Romania, and Finland. The differences in local climate and flour types likely affect their characteristics.

2. Fermentation Preferences: Compared to other starters, Stinkie is more acidic and lighter, likely due to being kept at cooler temperatures.

3. Acidity and Age: Stinkie has a pH level of 3.7, similar to other starters, but is significantly older at 11 years, while most samples are under 5 years old.

4. Yeasts and Bacteria: Stinkie contains about 41.69 million yeast cells and 2.82 billion bacteria cells per gram, which is above average. This might be due to its age.

The second part of the report analyzed the specific types of yeast and bacteria in Stinkie. It showed that Stinkie has a dominant type of bacteria (Lactobacillus brevis) and only one kind of yeast (Saccharomyces Cerevisiae), suggesting a lack of variety over time.

The researchers provided an AI assistant called Dough-Pro to help explore the data, but I prefer the detailed report and FAQ they also included. Overall, I find this citizen science project rewarding and look forward to similar studies in the future.

The article discusses the concept of personal continuity and change over a lifetime. It starts with the author's reflections on childhood memories and how they relate to his current identity as a father. People have differing views on whether they remain the same throughout their lives or change significantly. Some feel a strong connection to their past selves, while others see their past as a separate life.

The author references the Dunedin study, which tracked the development of children over decades, revealing how personality traits can persist or evolve. The study categorizes children based on temperaments, showing that while some traits remain stable, others can lead to different life paths.

Philosophers like Galen Strawson present varying perspectives on identity, with some viewing life as a continuous narrative and others seeing it as episodic. The article emphasizes that personal stories about change can shape our understanding of ourselves, suggesting that neither perspective is entirely right or wrong.

Ultimately, the author concludes that as we grow and reflect on our experiences, our understanding of who we are also evolves. The journey of self-discovery is ongoing, blending elements of both continuity and change throughout life.

Summary: Linux in Excel

Linux can run in Excel using a mini-rv32ima emulator. This emulator is created as a separate DLL file that is called by a VBA macro. The macro sends commands to the emulator and displays the results in the spreadsheet.

Although the project is quite buggy and not fully optimized, it was done for fun rather than as a serious tool. Instead of rewriting the emulator in VBA or using Excel formulas, the existing emulator was used.

To build the DLL, you need to use Microsoft Visual C++ (MSVC) with the command: cl dllmain.c /LD /Fe fun.dll. After creating the DLL, update the Excel file to point to its location. You can input commands by typing in cell C2.

JetBrains primarily focuses on developer tools and does not have a separate cloud services business like competitors, which pressures them to offer more community-friendly pricing. Despite their popular IDEs, the company faces challenges in maintaining customer trust and satisfaction with its AI offerings.

Albert Stevens (1887–1966) was an American house painter known for surviving the highest recorded radiation dose in a human. In 1945, he was injected with plutonium without his consent during a secret government experiment, mistakenly believing he had terminal cancer. He received a substantial radiation dose of about 64 Sv over 20 years, significantly higher than the current safe limit for radiation workers.

Stevens was chosen for the experiment because he was thought to be near death. After surgery for what was believed to be cancer, it was discovered he had only a benign gastric ulcer. His case, along with those of other subjects injected with plutonium, raised ethical concerns about informed consent and the treatment of human subjects in medical research.

Investigative journalist Eileen Welsome later brought public attention to Stevens's story, highlighting the unethical nature of these experiments. Her work led to governmental investigations and discussions about compensating victims of similar radiation studies. Stevens died of heart disease in 1966, and his remains are stored for scientific study.

Summary: Using Zip Bombs to Protect Your Server

Ibrahim Diallo discusses the use of zip bombs as a method to protect servers from harmful bots. While many bots help with content discovery, some are malicious, leading to issues like spam or server attacks. Diallo shares a personal experience where bots exploited a vulnerability in his previous workplace.

A zip bomb is a small compressed file that, when decompressed, expands to a much larger size, overwhelming the machine handling it. This technique takes advantage of the gzip compression, which is commonly used to speed up data transmission on the internet.

Diallo uses zip bombs to deter malicious bots by serving them a large compressed file that crashes their systems when they attempt to decompress it. He explains how he detects suspicious activity and then sends a zip bomb response.

He provides a command to create a zip bomb file and advises caution, as it could also crash the user's own device. While effective against unsophisticated bots, zip bombs are not foolproof and can be bypassed by more advanced bots.

Overall, zip bombs serve as a creative solution for mitigating unwanted bot traffic and protecting server resources.

Summary:

1. Background: PostgreSQL is a widely used open-source SQL database that supports various transaction isolation levels through multiversion concurrency control (MVCC). Amazon RDS for PostgreSQL is a managed service on AWS that automates many database management tasks. It offers a primary endpoint for read-write transactions and a secondary endpoint for read-only transactions. However, the secondary nodes do not support the strongest isolation level, which is "Serializable."

2. Test Design: The tests were conducted using a modified version of Jepsen’s test library for PostgreSQL on Amazon RDS. An RDS cluster was created, and tests were run on a single EC2 instance. The main workload involved transactions using lists of unique integers stored in a single row.

3. Results: The tests revealed that Amazon RDS for PostgreSQL 17.4 experienced G-nonadjacent cycles, indicating violations of Snapshot Isolation. These cycles included transactions that failed to observe each other's changes, which should not happen in standard PostgreSQL. This suggests that Amazon RDS may provide a weaker consistency model known as Parallel Snapshot Isolation. Various anomalies were observed across several versions of PostgreSQL.

4. Discussion: The findings indicate that multi-AZ clusters in Amazon RDS for PostgreSQL do not guarantee Snapshot Isolation and offer weaker safety than single-node PostgreSQL systems. Users should review their transaction structures and consider using only the primary endpoint for critical transactions to avoid potential issues. The report highlights the need for further exploration of Amazon RDS's behavior, as it can identify bugs but not guarantee overall correctness.

Google Play's app marketplace has seen a dramatic drop in the number of available apps, decreasing from about 3.4 million at the start of 2024 to approximately 1.8 million now, a decline of 47%. This reduction is not part of a broader trend, as Apple’s iOS App Store has slightly increased its app count during the same period.

The drop in apps could benefit Android users by making it easier to find quality apps, as Google has been purging lower-quality and scammy apps. Historically, Google’s less strict app review process allowed many poor-quality apps to remain, while Apple has maintained strict review standards.

In July 2024, Google announced it would raise its app quality requirements, leading to the removal of apps that had limited functionality or content. This included static apps, those with minimal content, and apps that served no purpose. Google has also implemented stricter verification and testing for new developers and increased human reviews to catch deceptive apps.

Additionally, Google cited its investments in AI for better threat detection and privacy policies, which helped prevent over 2.36 million policy-violating apps from being published.

A new EU regulation requiring developer transparency may have also influenced app availability, but it didn’t affect Apple’s app count. Appfigures noted a decline in Google Play apps even before the official purge began. However, app releases on the platform have increased by 7.1% year-over-year as of April 2024.

Recreation researchers are exploring ways to reduce the negative impact of human activity on public lands while making these areas more accessible to visitors. Popular hiking destinations like the Crestone Needle in Colorado see thousands of hikers each year, leading to issues such as litter and trail erosion. To address these challenges, park and forest services implement strategies to manage visitor behavior rather than simply restricting access.

Traditionally, crowd control methods involved limiting the number of visitors or charging fees, but modern approaches prioritize encouraging responsible behavior. Researchers are using data from surveys, interviews, and technology like drones to evaluate the effectiveness of these strategies. For example, creating well-designed trails can guide hikers and reduce environmental damage.

Behavior change strategies, such as community-based social marketing, help identify and address the reasons why visitors might harm the environment. While some researchers argue against strict visitor limits, they acknowledge that such measures may be necessary in fragile areas.

Recent studies show that managing visitor numbers isn’t the only solution; the design of trails and areas plays a significant role in minimizing ecological disturbance. Researchers emphasize the importance of making public lands accessible to foster a connection between people and nature, which is crucial for conservation efforts. Overall, ongoing research aims to provide effective management strategies that benefit both the environment and outdoor enthusiasts.

CoRT (Chain of Recursive Thoughts) Summary

CoRT is a method that enhances AI thinking by allowing it to argue with itself multiple times to improve its responses. It encourages the AI to doubt its initial answers, generate alternatives, and select the best one.

Key Points:

• CoRT helps AI models think more deeply and creatively.
• Testing with the Mistral 3.1 24B model showed significant improvements, especially in programming tasks.

How It Works:

1. The AI generates an initial response.
2. It determines how many rounds of thinking to perform.
3. For each round, it:
   • Creates three alternative responses.
   • Evaluates all responses.
   • Chooses the best one.

The final answer comes from this "battle" of responses.

Using CoRT:

• For Windows, run start_recthink.bat to install dependencies.
• For Linux, follow specific commands to set up the environment and run the program.

Secret Sauce:

• The effectiveness comes from self-evaluation, generating competitive alternatives, iterative refinement, and adjusting the depth of thinking.

Contributions and Licensing:

• Contributions to improve CoRT are welcome, and it is licensed under MIT, meaning it's free to use and modify.

Microsoft's Remote Desktop Protocol (RDP) allows users to log in with revoked passwords, which has raised security concerns. This means that even after changing a password, the old one can still grant access to a machine, creating a potential backdoor for unauthorized users. Microsoft claims this is intentional to prevent users from being locked out of their accounts, and they have no plans to change this behavior.

Security researcher Daniel Wade highlighted that this design goes against common expectations that changing a password cuts off access. He explained that old passwords can work indefinitely for RDP logins, which bypasses security measures like multifactor authentication. This poses a risk, especially if a user's Microsoft or Azure account has been compromised.

The issue stems from how Windows caches credentials on local machines. When a user first logs in, their password is stored locally, allowing continued access even if the password is changed online. Microsoft has updated its documentation to inform users about this behavior, but many may still overlook it. Security experts suggest that users should configure RDP to rely solely on local credentials to enhance security after a password change.

The article discusses the common belief that ancient tribes used psychedelics like ayahuasca and magic mushrooms for healing practices. Austrian anthropologist Bernd Brabec de Mori, who spent years living with the Shipibo people in the Amazon, challenges this narrative. His research suggests that ayahuasca's use is not as ancient as previously thought, likely spreading through the Amazon over the last 300 years, rather than being a millennia-old tradition.

Brabec de Mori highlights a pattern of stories told to tourists that often differ from the lived realities of Indigenous peoples. His findings indicate that many traditional narratives about ayahuasca’s origins are inaccurate, as some communities only started using it in the last 50 years. This challenges the widespread belief that psychedelic use is ancient and universal, as shown by other researchers like Martin Fortier, who found limited evidence of early psychedelic use among Indigenous cultures.

The article also critiques the idea that psychedelics have always been used for therapeutic purposes by shamans. Instead, it presents shamans' use of these substances as part of broader spiritual practices, often involving supernatural elements. The modern perception of psychedelics as merely psychotherapeutic tools may stem from romanticized views of Indigenous cultures and the interests of contemporary society in these substances.

Overall, the text calls for a reevaluation of the historical narratives surrounding psychedelics, suggesting that they are not as deeply rooted in ancient traditions as commonly believed.

Raspberry Pi has improved its production process by changing how it solders components on its boards, resulting in a 50% reduction in product returns. Previously, Raspberry Pi used a method that involved separate steps for soldering smaller surface-mount devices (SMDs) and larger through-hole components, which was time-consuming and prone to defects.

Now, they use a technique called intrusive reflow soldering, where both types of components are soldered simultaneously. This method has sped up production by 15% and reduced carbon dioxide emissions by 43 tonnes per year. The new process not only enhances product quality but also makes manufacturing more efficient.

Ukraine's air force has managed to survive against Russian attacks since the war began in February 2022, despite being heavily outnumbered. They adapted by dispersing their aircraft and personnel to smaller airfields, making it harder for Russian missiles to hit them. This strategy has allowed them to continue flying missions for over three years.

In contrast, Taiwan’s air force faces a much more challenging situation. With only about 50 airfields compared to Ukraine’s 900, Taiwan has fewer options for dispersing its aircraft. The threat from China is significant, with a large arsenal of missiles that could quickly neutralize Taiwan's air capabilities in the early stages of a conflict.

Experts suggest that Taiwan should focus on ground-based air defenses and other concealment tactics rather than investing heavily in fighter jets, as its air force would likely have a very short lifespan in a full-scale war with China. In summary, while Ukraine has found ways to survive, Taiwan's air force is at a severe disadvantage and may struggle to withstand an initial attack.

Summary of "Strings Just Got Faster"

In JDK 25, the performance of the String class has been significantly improved, particularly the String::hashCode function. This means that using Strings as keys in static, unmodifiable Maps can lead to faster performance.

For example, an immutable Map of system calls (like "malloc" and "free") can now benefit from these enhancements. When the Map is set up, the new performance allows the system to quickly look up values without recalculating the hash code each time, resulting in more than an 8x speed increase.

The improvement works by marking the internal hash code field of a String as @Stable, which lets the virtual machine optimize lookups. This means operations are streamlined, allowing direct calls to native methods.

However, there's a limitation: if a String's hash code is zero, the optimization won't apply. Thankfully, this situation is rare. While the @Stable annotation is for internal use only, a future update (JEP 502) may allow similar benefits for user code.

You can try out these improvements by downloading JDK 25 today.
