Summary: Keeping a Postgres Queue Healthy

Maintaining a healthy job queue in Postgres requires careful management, similar to how a healthy digestive system processes food. Postgres is effective for various workloads, including job queues, but it faces unique challenges, especially when multiple types of work run simultaneously.

Key Points:

1. Job Queue Basics: A job queue in Postgres typically involves transient rows that are inserted, processed, and deleted quickly. The queue's health depends on efficient transaction management and cleanup.

2. Dead Tuples Issue: When rows are deleted, they are marked as "dead" but not physically removed until cleaned up by a vacuum operation. If many dead tuples accumulate faster than they can be cleaned, it can slow down database performance.

3. MVCC (Multi-Version Concurrency Control): Postgres maintains multiple versions of rows for transaction isolation, which leads to dead tuples. Cleanup can be hindered by long-running transactions or overlapping queries that keep these dead rows from being removed.

4. Autovacuum Limitations: While Postgres has an autovacuum feature to clean up dead tuples, it can be ineffective if transactions are active and blocking cleanup. This can result in performance degradation over time.

5. Solutions and Tools: To maintain healthy queues, it’s important to configure autovacuum settings properly and use tools like Traffic Control from PlanetScale. Traffic Control allows for granular management of query resources, helping to prevent lower-priority queries from interfering with the job queue.

6. Recent Improvements: Newer versions of Postgres have introduced features that help manage job queues better, but the underlying issue of dead tuples accumulating remains. Effective management strategies, including retry logic for blocked queries, can help maintain performance.

In summary, running a job queue effectively in Postgres requires understanding transaction management, cleanup processes, and utilizing modern tools to ensure that dead tuples do not hinder performance.

Summary: How Much Linear Memory Access Is Enough?

In high-performance computing, the arrangement and access pattern of memory are crucial for efficiency. Common belief is that using large, contiguous memory blocks is best, but this has limits. The author conducted experiments to find the optimal block size for processing data, leading to several key findings:

1. Block Size Recommendations:

   • 1 MB blocks are generally sufficient for most workloads.
   • 128 kB blocks work well if processing speed is around 1 cycle per byte.
   • 4 kB blocks are adequate when processing speeds exceed 10 cycles per byte.

2. Experiment Setup:

   • The experiments involved measuring the performance of different block sizes (ranging from 32 bytes to 2 MB) and working set sizes (1 MB to 64 MB).
   • Techniques were employed to ensure consistency, such as randomizing data layout and "clobbering" cache before tests.

3. Results:

   • Larger block sizes showed diminishing returns in performance beyond 128 kB.
   • Performance varied based on the type of computation; for example, SIMD (Single Instruction, Multiple Data) operations had different optimal block size requirements compared to simpler scalar operations.

4. Conclusions:

   • For most applications, particularly when processing overhead is more than 1 cycle per byte, a block size of 128 kB is sufficient.
   • The findings suggest that while larger contiguous memory blocks can be beneficial, they may not be necessary for optimal performance in many scenarios.

The author encourages further testing on different systems to refine these guidelines and explore additional factors such as multi-threading and varied workloads. The full experimental data and code are available online for others to review and test.

Researchers have found that the largest known group of wild chimpanzees in Uganda has been in a violent "civil war" for eight years. The Ngogo chimpanzees, which used to live peacefully together, have split into two groups—Western and Central—and have been involved in numerous attacks since 2018, resulting in 24 killings, including 17 infants.

The conflict began in 2015 when tensions rose between the two groups, leading to a breakdown of their previously harmonious relationships. Several factors have contributed to the violence, including the deaths of key individuals, changes in leadership, and a respiratory epidemic that weakened social ties.

The study suggests that this behavior can shed light on the origins of human conflict, as chimpanzees, closely related to humans, have turned against former companions based only on group membership. Researchers emphasize the importance of understanding group dynamics in both animal behavior and human societies to prevent conflicts.

Bitcoin miners are currently facing significant financial losses, producing each bitcoin at an average cost of $88,000 while the market price is around $69,200. This results in a loss of nearly $19,000 per bitcoin, largely due to rising energy prices and geopolitical tensions, particularly related to the ongoing war in the Middle East.

The conflict has led to increased electricity costs and a decline in mining efficiency, with the network's difficulty dropping by 7.8%. Many miners are now forced to sell more bitcoin to cover expenses, contributing to downward pressure on the market.

The blog post discusses the concept of "productive procrastination," where people engage in tasks they enjoy instead of focusing on necessary work. The author reflects on their own experiences with procrastination, particularly in video editing, where they find it easier to work on new projects rather than older ones.

Key points include:

1. Procrastination Dynamics: Procrastination often arises from a conflict between two brain systems: the limbic system, which seeks to avoid negative emotions, and the prefrontal cortex, which is responsible for planning and impulse control. When tasks trigger anxiety or fear, the brain opts for avoidance.

2. Novelty and Motivation: The author notes that they are more motivated by new tasks because the brain's reward system responds positively to new stimuli. This makes it hard to return to older, unfinished tasks, leading to procrastination.

3. Guilt and Avoidance: Feeling guilty for not completing tasks can create a cycle of avoidance. The more productive one feels doing other tasks, the less motivation there is to tackle the main task, which may be associated with negative emotions.

4. Possible Solutions: To combat this, the author suggests making older projects feel new again, such as trying new techniques or labeling emotions to reduce avoidance. Self-forgiveness is also important, as it can help lessen guilt associated with procrastination.

5. Practical Tips: Setting specific times to work on tasks and understanding the psychological aspects of procrastination can help individuals overcome it.

Overall, the article emphasizes understanding the psychological reasons behind procrastination and finding creative ways to engage with necessary tasks.

This chess variant was first introduced by Martin Gardner in July 1980 in Scientific American.

A recent investigation by The Guardian highlights how the online prediction market, Polymarket, is influencing news and perceptions of truth, especially regarding conflicts like the war in Ukraine. Users on Polymarket are betting substantial amounts on events such as whether Russia will capture the city of Kostyantynivka, with over $500,000 at stake. The platform is increasingly likened to a casino where users attempt to profit from real-world events, including wars and political outcomes.

Participants often discuss strategies in online groups, and some even try to manipulate information to secure their bets. Polymarket claims to provide valuable insights that traditional news sources may miss, but critics argue it could lead to unethical behavior, including influencing market outcomes and public narratives.

As the platform grows, it has attracted significant investment, and its data is being used by major financial institutions. However, concerns arise about the potential for market manipulation and the integrity of the decision-making process, which relies on an anonymous group of cryptocurrency holders to adjudicate bets. Critics warn that this setup may lead to corruption and question who gets to decide what is considered "truth" in these markets.

In summary, Polymarket is a controversial platform where users bet on future events, impacting how information is perceived and potentially influencing broader financial markets, raising ethical concerns about the intersection of gambling and real-world events.

The text discusses the relationship between language models (LMs) and maps, using an analogy to explain how LMs represent reality. Here are the key points:

1. Maps as Reductions: The text begins with a reference to Borges' story about an empire that created a map as large as itself, which later became useless. It suggests that maps are valuable because they simplify complex realities into manageable representations.

2. Advancements in LMs: LMs have become highly effective, not just representing information but also influencing how we engage with it. Our interactions with technology increasingly involve these models, affecting how we approach tasks and think.

3. Stages of Representation: Drawing on Baudrillard's theory, the text outlines four stages of how representations connect to reality:

   • Stage One: The representation closely mirrors reality.
   • Stage Two: The representation distorts reality, providing a smooth but potentially misleading view.
   • Stage Three: The representation obscures the absence of reality, leading to complacency in seeking information.
   • Stage Four: The representation may completely detach from reality, creating confusion about what is true.

4. Unique Nature of LMs: Unlike static maps, LMs provide personalized experiences that change based on user input. This flexibility allows deeper exploration of topics but also presents challenges in discerning accuracy.

5. Skill Development: Effectively using LMs requires developing a skill to navigate their outputs critically. This involves recognizing when to trust the information and when to seek further verification.

6. Tacit Knowledge: The ability to use LMs well is a subtle, personal skill that cannot easily be codified into rules. It involves a deeper understanding and intuition about the information presented.

7. Future of LMs: The text concludes that current LMs are the least advanced they will ever be, and as they improve, the importance of learning to navigate them will only increase.

Overall, the discussion emphasizes the need for critical engagement with LMs as they become integral tools in our information landscape.

Summary:

Adam Rice explores an unconventional way to use DNS (Domain Name System) by storing and running the video game DOOM directly from TXT DNS records. DNS translates domain names into IP addresses and includes TXT records that can hold arbitrary text without validation, making them a sort of free, global storage option.

Rice demonstrates this by encoding DOOM's files into chunks and uploading them as roughly 2,000 TXT records using CloudFlare. A PowerShell script retrieves these records, reassembles them in memory, and runs the game without saving any files to disk. He modified a C# version of DOOM to load from memory rather than from disk, cutting audio to reduce the number of records needed.

Ultimately, this project showcases how a simple and historically boring protocol like DNS can be creatively abused for unexpected purposes, like running a classic video game. The full project details are available on GitHub.

The article discusses the rise of "synthetic sampling" in political polling, where AI models simulate survey responses rather than gathering data from actual people. Companies like Aaru and Electric Twin claim their AI-generated polls can predict election outcomes better than traditional polls. However, many experts remain skeptical, arguing that these models can't replace real polls since they don't collect new data and can introduce biases.

Key points include:

1. Synthetic Polling: AI models simulate public opinion by creating fictional survey respondents based on demographic profiles. While these models can generate quick and cost-effective results, they lack the ability to gather genuine public sentiment.

2. Skepticism from Pollsters: Many pollsters emphasize the importance of actual data collection to accurately reflect public opinions. They believe that AI-generated responses may not capture the nuances of human behavior and emotions.

3. Accuracy Claims: While some companies assert their models can outperform traditional polling, evidence supporting this claim is limited. Critics argue that AI models often struggle with varied responses and can misrepresent voter sentiments.

4. Market Adoption: Despite concerns, synthetic sampling is gaining traction in various sectors, including market research. However, there’s a risk that AI could undermine the integrity of online polling if used to manipulate survey responses.

In summary, while synthetic polling offers new methods and efficiencies, it does not replace the need for traditional polling that accurately reflects the views of real voters.

Summary of Split Locks on x86-64

What are Split Locks?

• Split locks occur during atomic operations when memory access spans two cache lines.
• These operations are crucial for multithreaded programming, as they allow actions to be performed without interference from other threads.

Performance Issues:

• Modern Intel and AMD CPUs can’t lock two cache lines simultaneously, leading to the use of "bus locks."
• Bus locks are slow and can severely disrupt performance across other cores, causing significant latency.
• Newer CPU architectures have features to detect and manage split locks, with Linux implementing delays to reduce their negative impact.

Testing and Results:

• Tests across various CPU models showed that split locks drastically worsen memory access times, especially past the L1 cache, often by ten times or more.
• Different CPUs exhibited varying degrees of performance degradation:
  • Intel Core Ultra 9 Arrow Lake: High latency for split locks, affecting L2 cache misses.
  • AMD Ryzen 9 9900X (Zen 5): Similar issues, with severe penalties for memory access.
  • Intel Alder Lake: While split lock performance is poor, it mitigates the impact on other applications.
  • AMD Piledriver: Best performance for split locks among tested CPUs, with minimal impact on cache hits.

Linux's Mitigation Strategies:

• Linux introduces delays for processes using split locks to maintain consistent performance, particularly in multi-user environments.
• However, this approach may be excessive for consumer systems where such performance issues are less common.

Conclusion:

• Programmers should avoid split locks due to their detrimental effects on performance.
• There is potential for hardware and software improvements to better handle split locks and reduce their impact on system performance.

In 2019, I began a project called fennel-cljlib, aiming to incorporate some features of Clojure into the Lua runtime via the Fennel programming language. This library added basic functions and macros from Clojure, along with features like lazy sequences, immutability, a testing library, and a version of Clojure's core.async. It was mostly a personal project, with limited real-world use and primarily served as an experiment.

Recently, I started a new project called ClojureFnl, a compiler that translates Clojure code into Fennel using fennel-cljlib as its foundation. Although it's still in early development, it can compile many Clojure files, but there are challenges in running the compiled code due to incomplete standard library support.

One major issue I faced was the slow performance of my initial immutable data structures. They relied on a copy-on-write approach, which became inefficient, especially for arrays. I realized I needed to create a more efficient library, leading to the development of immutable.fnl, which includes better implementations of hash maps, sets, vectors, and other data structures inspired by Clojure.

The new library features Persistent HAMT for hash maps, allowing efficient operations. However, they are still slower than Lua's native tables. I also implemented persistent vectors and red-black trees for sorted maps and sets, with specific techniques to optimize performance.

I also reworked my lazy list implementation and created a persistent queue with fast append and remove operations. With these improvements, I can now refocus on developing the ClojureFnl compiler, which I hope to discuss in my next update.

The article explains that the Privacy & Security settings on macOS can be misleading regarding app access to protected folders. The author demonstrates this using a simple app called Insent.

Key points include:

1. Misleading Access: Privacy settings may indicate that an app doesn't have access to a folder, while it might actually have unrestricted access.

2. Insent App: The app allows users to see how it can access files in the Documents folder with and without consent. It uses two functions: one that requires user consent to access files and another that allows access when the user selects a folder.

3. Demonstration Process: The article outlines steps to show that Insent can access the Documents folder even when its access is supposedly disabled in Privacy settings.

4. Technical Details: The app operates normally and does not use any advanced tricks. The system's privacy controls (TCC) can be bypassed based on user intent when selecting folders.

5. Conclusion: The Privacy & Security settings do not accurately reflect access control, potentially allowing apps to access protected information without users' awareness. Users need to be cautious, as resetting access requires a specific Terminal command.

Overall, the article warns that app permissions in macOS can be misleading and emphasizes the need for users to be vigilant about their privacy settings.

France is moving away from Microsoft Windows for its government computers, planning to switch to the open source operating system Linux. This decision is part of an effort to reduce reliance on U.S. technology and to take control of its digital infrastructure. French minister David Amiel emphasized the need for digital sovereignty and control over data.

The transition will start with the French government's digital agency, DINUM, but no specific timeline or Linux versions have been announced. This move aligns with a broader trend in Europe, as lawmakers are increasingly concerned about dependence on U.S. tech companies.

Recently, France also decided to stop using Microsoft Teams for video conferencing, opting for a French-made tool instead. Additionally, they plan to migrate their health data platform to a new trusted system by the end of the year.

A recent supply chain attack targeted CPUID, which distributes software like CPU-Z and HWMonitor. This attack has led to malware being distributed through these programs, posing security risks for users. It's important to be cautious and stay informed about these vulnerabilities.

A study from UC Davis and SUNY Buffalo found that Magellanic penguins in Patagonia can monitor environmental pollution using small, chemical-detecting leg bands. During their breeding season, 54 penguins wore silicone passive samplers that collected data on chemicals in their environment over a few days. The results showed that over 90% of the bands detected per- and polyfluoroalkyl substances (PFAS), known as "forever chemicals," even in this remote area.

This non-invasive method allows researchers to track pollution without harming the penguins. It revealed a shift from older PFAS to newer replacement chemicals, indicating that these pollutants are spreading even to isolated ecosystems. The researchers aim to expand this approach to other species, like cormorants, to enhance environmental monitoring and address wildlife health and conservation issues.

The text discusses the global helium supply and its significance, especially in light of disruptions caused by geopolitical events, like the war in Iran. Helium is primarily produced as a byproduct of natural gas extraction, with Qatar and the US being the largest suppliers. The closure of the Strait of Hormuz has led to increased helium prices and potential shortages.

Helium is unique due to its low boiling point, making it essential for cooling in applications like MRI machines and semiconductors. Its properties allow it to remain liquid at extremely low temperatures, which is critical for superconducting magnets. Various industries, including medical imaging, semiconductor manufacturing, and aerospace, heavily depend on helium, and in many cases, there are no good substitutes.

Summary:

The blog post by Matthew McPherrin discusses the challenges faced by Let’s Encrypt, a Certificate Authority, in managing test certificates for websites. Unlike tools that help maintain valid certificates, there are few resources for ensuring certificates are intentionally broken or expired.

Let’s Encrypt needs to host three types of test sites for each root certificate: one with a valid certificate, one with an expired certificate, and one with a revoked but valid certificate. While valid and expired certificates are relatively easy to manage, ensuring a revoked certificate remains non-expired is more complex.

To address this, Let’s Encrypt developed a Go program that automates the management of these certificates. It uses a library called Lego to request and revoke certificates and checks their status through Certificate Revocation Lists (CRLs). The program handles the timing for transitioning certificates to ensure they are in the correct state before being served by the web server.

The blog also highlights that revocation checking can vary by browser, with some modern solutions improving reliability. Lastly, the code for this project is open-source, allowing other Certificate Authorities to utilize it for their testing needs.

Let’s Encrypt encourages support for their nonprofit work in promoting secure internet practices.

In the 1920s and 30s, KPS Menon, a Malayali bureaucrat from Kerala, faced a cultural challenge with his family’s helper, Nani Amma, who refused to wear a blouse, a garment expected in other parts of India. In rural Kerala, going bare-breasted was common until recent times, and it wasn't seen as immodest. The idea that women, especially of marginalized castes, should cover their breasts is a modern concept that arose during the colonial period, influenced by European values.

Historically, across various regions in India, both men and women often went topless. Accounts from travelers in Kerala described both men and women wearing minimal clothing, indicating that bare-chestedness was normal in their society. This cultural norm began to shift with the introduction of colonial expectations, leading to the perception of uncovered female bodies as inappropriate.

The shift towards covering up, particularly for women, was influenced by Western notions of decency brought by missionaries and colonial authorities. The introduction of the blouse became symbolic of modernity and social status, leading to a decline in traditional dress practices.

The narrative around Nangeli, an Ezhava woman who is said to have protested a tax on women covering their breasts, is often misinterpreted. The tax was actually a caste-based poll tax, not specifically for breast covering. Nangeli's story has evolved into a legend highlighting resistance against caste oppression, but it is essential to understand the historical context to avoid modern misconceptions.

Overall, the evolution of dress in Kerala reflects broader social changes, with women transitioning from traditional bare-breasted attire to modern clothing influenced by colonial and contemporary values. This transformation has been complex, involving issues of caste, gender, and cultural identity.

On April 10, 1989, Intel announced the 486 CPU at a high price of $950 per chip in bulk. Analysts at the time were skeptical about the chip's potential, with warnings that the impressive speed boost from previous models might not continue. However, predictions about demand for the 486 due to increased graphics and multitasking needs proved accurate.

Initial reactions highlighted that while the 486 had advanced technology—like 1.2 million transistors and improved efficiency—it was seen more as an evolution rather than a revolutionary change. The first 486 systems were expected to sell for $10,000 to $15,000, making them very expensive.

The real demand for faster computers emerged with the release of Windows 3.0 and later Windows 3.1, which required more processing power. Although the 486 was capable for several years, it eventually struggled with newer software like Word 97. The 486 also became popular for gaming, particularly with titles like Doom, which needed its enhanced capabilities.

Intel eventually introduced faster variants, achieving speeds over 50 MHz, which solidified the 486's place in the market before the introduction of even faster processors.

The article discusses how government report covers used to be artistic and eye-catching, particularly throughout the 20th century. Many reports featured creative illustrations that conveyed important messages about topics like transportation and safety. For example, a 1982 report on transporting watermelons included a whimsical image of a giant watermelon on a truck, while a 1964 report on highway deaths had a dramatic design inspired by famous movie posters.

Rachel Cole, a curator at Northwestern University Transportation Library, has been sharing these artistic covers on social media to engage the public and highlight the library's extensive collection on transportation. Unlike today’s generic report designs, these older covers often showcased creativity and thoughtfulness, making them memorable and informative.

However, starting around 2012, report designs shifted to simpler and less engaging styles, often relying on stock images and basic templates, likely due to budget constraints and the rise of digital formats. This change has led to a loss of visual impact and creativity in government reports, which used to draw attention and convey complex information in an engaging way. The article emphasizes the importance of good design in making reports more accessible and memorable.

Elizabeth Holmes, the founder of Theranos who is serving an 11-year prison sentence for fraud, recently updated her profile on X (formerly Twitter) and tweeted for the first time in nearly a decade. She shared an image of Martin Luther King Jr. with a quote about justice, and then engaged with tweets from an entrepreneur named Bryan Johnson, expressing support for his ideas on longevity.

Holmes is currently in a minimum-security prison where inmates can buy tablets for educational and entertainment purposes, but these tablets do not have internet access. Instead, they can make monitored phone and video calls, as well as use a secure messaging system. It’s unclear how she is able to tweet, but it seems likely that she is dictating her posts to someone outside the prison, similar to other inmates who have maintained online presences.

Her recent activity on social media comes amid publicity surrounding her case, including new billboards claiming her innocence and her fiancé announcing a new blood diagnostic startup. The timing of her tweets suggests someone may be reading tweets to her over the phone, or there is a possibility that someone else is posting on her behalf.

Summary of 2D Quadcopter Simulation

This post details the creation of a simple simulation for a 2D quadcopter, a drone with four propellers. The focus is on understanding the quadcopter's dynamics and how to implement a simulation in Python.

Key Steps:

1. Understanding the Quadcopter Model:

   • The quadcopter is modeled as a rigid body with mass (m) and two arms of length (\ell).
   • Its motion is defined in a 2D plane with (y) as the horizontal axis and (z) as the vertical axis. The rotation angle (\phi) influences its movement.

2. Equations of Motion:

   • Using Newton-Euler equations, the motion equations are derived:
     • Horizontal motion: (m \ddot{y} = - (F_1 + F_2) \sin \phi)
     • Vertical motion: (m \ddot{z} = (F_1 + F_2) \cos \phi - mg)
     • Rotational motion: (I \ddot{\phi} = (F_1 - F_2) \ell)

3. State-Space Representation:

   • The system is reformulated into state-space form to facilitate simulation. The state vector includes position, angle, and their respective velocities.

4. Simulation in Python:

   • The dynamics of the quadcopter are defined in Python using the derived equations.
   • The simulation is set up with initial conditions and thrust inputs to model the quadcopter's behavior over time.

5. Results of the Simulation:

   • The simulation is run under two conditions: zero torque and non-zero torque.
   • In the zero torque case, the quadcopter remains stable and ascends due to constant thrust.
   • In the non-zero torque case, the quadcopter rotates and eventually descends when thrust is insufficient to counteract gravity.

6. Visualization:

   • The results are visualized through plots showing the positions, velocities, and input forces over time.

This simulation serves as a foundational step for designing controllers or training reinforcement learning agents for quadcopters.

Torched is celebrating its 2nd anniversary with a series of events from April 20 to April 24. You can participate in just one event or join every day for five days. The events will include talks, toasts, and treats.
