For remote teams of 2-10 people, creating individual "ramblings" channels in your chat app can be beneficial. These channels allow team members to share thoughts without cluttering main group chats, acting like personal journals or microblogs.

Team members can post brief updates 1-3 times a week on various topics, such as project ideas, interesting articles, suggestions, or personal photos. Each channel is named after the team member, and only they can start new messages, while others can reply in threads.

These channels should be located at the bottom of the channel list, muted by default, so there's no pressure to read them.

At Obsidian, where this practice started two years ago, ramblings have been effective in maintaining team connections without disrupting work. They often lead to valuable ideas and solutions. The team also meets in person once a year, and ramblings help keep the team's bond strong throughout the year.

Researchers have used high-resolution imaging to reveal intricate tattoos on a 2,500-year-old Siberian "ice mummy." The tattoos include designs of leopards, a stag, a rooster, and a mythical griffin, showcasing the advanced skills of the Pazyryk people, a nomadic culture from the Altai mountains. The woman, estimated to be about 50 years old at the time of her death, had tattoos that were difficult to see with the naked eye.

The research team, which included a tattoo artist familiar with ancient techniques, concluded that the tattoos were likely applied using a stenciling method and tools made from animal materials. The quality of the tattoos varied between her arms, suggesting they were done by different artists or that mistakes occurred during the process.

Dr. Gino Caspari, the lead researcher, emphasized the sophistication of the ancient culture reflected in the tattoos. Some tattoos were damaged during burial preparations, indicating they held personal significance during the woman's life but were not intended for the afterlife. This study provides valuable insights into the tattooing practices of an ancient society, highlighting their artistry and cultural importance.

The ski rental problem is a well-known example in online algorithms that helps decide whether to rent or buy skis when the number of skiing days is uncertain. Here's a simplified summary of the key points:

1. Scenario: When going skiing, you don’t know how many days you'll need skis. Renting costs 111 currency units, while buying them costs a fixed amount (BBB).

2. Optimal Decision with Known Days: If you know you will ski for a certain number of days (k), the best approach is:

   • Buy skis if k is greater than or equal to BBB.
   • Rent skis if k is less than BBB.

   The cost in this case is the minimum of k or BBB.

3. Simple Online Algorithm: Without knowing k, a straightforward strategy is to buy skis after you have spent BBB on rentals. The cost would be:

   • If k is less than or equal to BBB, the cost is k.
   • If k is greater than BBB, the cost is BBB plus the days you rent.

   This algorithm can be at most twice as costly as the optimal decision if you knew k in advance.

4. Randomized Algorithm: A more advanced approach involves a randomized algorithm that aims to reduce expected costs. It uses probabilities to decide when to buy skis, resulting in an average competitive ratio of about ( \frac{e}{e-1} ).

5. Probability Distribution: The algorithm determines a probability distribution to make decisions on when to buy skis, which is mathematically derived to optimize the expected cost.

6. Applications: Although this problem is fictional, the concepts can be applied in real decision-making scenarios involving uncertain outcomes.

7. Coding Example: A Python implementation of the randomized algorithm is provided for experimentation, illustrating how to calculate the optimal day to buy skis based on the input costs.

This problem highlights the trade-offs between immediate decisions and future costs when faced with uncertainty.

Summary: Writing a Basic Service for GNU Guix

This guide explains how to create a service in GNU Guix to automatically start the kmonad application at boot and keep it running until shutdown.

Key Steps:

1. Understanding Services: GNU Guix uses "services" to enhance the operating system's functionality. Each service can extend other services, allowing for better organization and management.

2. Service Types: We need to define a new service type for kmonad. This involves creating a kmonad-service-type which includes a name, description, and service extensions for accounts and the Shepherd init system.

3. Creating User Accounts: For the kmonad daemon, we define a user and group without login capabilities, similar to existing services like wesnothd.

4. Defining Shepherd Service: The service must specify how to start and stop kmonad, including requirements like waiting for udev and user processes to ensure they are running before kmonad starts.

5. Module Creation: The service code is packaged into a module that can be included in the system configuration.

6. Configuring the System: To use the new service, it is added to the system configuration file, specifying user accounts, packages, and any needed configurations.

7. Alternative Approach: A simpler method using simple-service might also be possible, making implementation easier.

By following these steps, users can effectively manage the kmonad daemon in a structured and maintainable way within the GNU Guix system.

The article discusses the challenges of displaying Icelandic personal names correctly in user interfaces due to the language's declension system, which alters noun forms based on grammatical cases. Each Icelandic name has four forms: nominative, accusative, dative, and genitive. Names are typically stored in the nominative case, which can lead to errors when used in sentences requiring different cases.

To address this, the author created a JavaScript library called "beygla" that can convert names into the appropriate grammatical case using a compact trie data structure, which stores declension patterns efficiently. The library uses data from Iceland's Database of Morphology, filtering it to include approved personal names.

The trie is designed to compress declension patterns, reducing its size significantly. This allows the library to maintain a small footprint in web applications while providing accurate declensions for most Icelandic names. The author shares technical details about how the trie is built, compressed, and optimized for lookups.

Ultimately, the library demonstrates a balance between size and accuracy, with a strict version available for contexts requiring complete correctness. The author reflects on the development process and encourages exploration of similar solutions for other languages with declension systems.

Summary: Understanding the /o Modifier in Ruby Regex

The /o modifier in Ruby regex stands for "oh the humanity!" and can cause unexpected behavior due to its caching mechanism. When using /o, the first time a regex with interpolations is evaluated, the result is cached and reused for subsequent calls, which can lead to unpredictable outcomes, especially in loops or multi-threading scenarios.

Key Points:

1. Regex Behavior: The /o modifier caches the result of the regex interpolation, meaning it only evaluates the regex once, regardless of how many times it's called afterward.
2. Example Confusion: A class called Matcher was used to check if a string matched any in an array. The method behaved unexpectedly because of the /o modifier, which caused it to cache the first input it received.
3. Performance vs. Risks: While /o can improve performance by avoiding repeated evaluations, it introduces risks of non-deterministic behavior, especially in threaded environments.
4. Threading Issues: The caching leads to situations where different threads may see different results depending on the order of execution, making debugging difficult.
5. Recommendation: The article advises against using the /o modifier due to its complexity and potential for bugs. Instead, developers should consider manually caching regex if optimization is necessary.
6. Alternatives: Implementing your own caching mechanism or using thread-safe constructs can provide more reliable performance without the pitfalls of /o.

In conclusion, the /o modifier can create confusing and hard-to-debug situations in Ruby programs, and it is recommended to avoid using it.

Researchers at Cornell University have created a method to "watermark" light in videos to help detect manipulated or fake content. This new technique embeds secret codes into the lighting of important events, like interviews, making it possible to identify whether a video has been altered. The hidden information, which is designed to be almost invisible to the human eye, is recorded in any video captured under the specially coded light.

The method involves using programmable light sources, such as computer screens, or attaching small chips to existing lights to create a unique lighting pattern. Each watermark contains a low-quality, time-stamped version of the original video, which helps identify inconsistencies if the video is modified.

This technology could help forensic analysts spot edits or alterations in videos that would otherwise be difficult to detect. Despite its promise, researchers acknowledge that the fight against misinformation is ongoing and adversaries will continue to develop new methods to deceive viewers.

Helion Energy has acquired land and started construction for the world's first fusion power plant. This plant aims to harness nuclear fusion, a process that could provide a clean and virtually limitless energy source. The project marks a significant step in the development of fusion energy technology.

MIT physicists have conducted a new version of the classic double-slit experiment, showing that light behaves both as a particle and a wave, but these two identities cannot be observed simultaneously. The experiment, led by Wolfgang Ketterle, used individual atoms as slits and weak laser beams to scatter photons.

This research confirms that the more information we gain about light's particle behavior, the less we can see its wave-like interference pattern. Ketterle notes that their work helps clarify a long-standing debate between physicists Albert Einstein and Niels Bohr about light's dual nature.

The experiment involved cooling over 10,000 atoms to near absolute zero and arranging them in a lattice to observe how light interacts with them. By adjusting the "fuzziness" of the atoms, researchers could control whether the light behaved like a particle or a wave.

Importantly, they found that the method of detecting light's path did not affect the fundamental nature of light, supporting quantum mechanical principles. Their findings were published in Physical Review Letters and contribute to the ongoing celebration of quantum science in 2025.

A North Korean defector, Jin-su, revealed that he was part of a secret IT operation where he worked abroad to earn money for the North Korean regime. Using fake identities, he applied for remote IT jobs in the US and Europe, earning around $5,000 a month, with 85% of his income sent back to North Korea. This scheme, which has been growing, especially during the pandemic, is estimated to generate between $250 million to $600 million annually for the regime.

Jin-su and his colleagues often impersonated Westerners to secure jobs, as North Koreans face significant international sanctions. He explained that many workers, while aiming for legitimate paychecks, sometimes resort to hacking or theft. Companies have reported encountering North Korean applicants, leading to challenges during hiring processes.

Despite the oppressive conditions in North Korea, Jin-su noted that workers abroad have more freedom and access to information, which can lead to realizations about their country's situation. While defecting is risky and rare, Jin-su managed to escape and now earns a legitimate income, feeling more fulfilled in his new life.

The text discusses the challenge of creating a Rubik's Cube scramble where no two squares of the same color are adjacent. The author initially struggled to achieve this and sought help online, learning about certain requirements for a "perfect scramble." These requirements included having every color on each face, no more than two squares of the same color on any face, and no touching squares of the same color, either side-by-side or diagonally.

To tackle the problem, the author realized that evaluating all possible Rubik's Cube arrangements (over 43 quintillion) wasn't feasible. Instead, they developed a program that generated cube arrangements while adhering to the specified criteria. They focused on corner and edge piece placements, ensuring that arrangements met the even swap parity requirement for solvability.

After five days of running the program, it found a single solution that fulfilled all requirements, producing 48 unique arrangements of the perfect scramble. The author notes that while the program could be optimized further, they successfully demonstrated that a perfect scramble is indeed possible, albeit with some limitations on additional requirements. The source code for the program is available online.

Robert Wilson, a renowned theater director and visual artist, has passed away. He was celebrated for his innovative and experimental approach to stagecraft, blending visual art with performance.

His influence on contemporary theater was significant, inspiring many artists and shaping the way stories are told on stage.

The text discusses cache eviction policies in computer architecture, particularly comparing Least Recently Used (LRU) and a two-random choice (2-random) strategy.

Key points include:

1. Eviction Policies: LRU is often favored because it keeps recently used items, but it can struggle when data exceeds cache size. In contrast, 2-random performs better when data is too large for the cache.

2. Miss Rates: In tests with various cache sizes (L1, L2, L3), LRU generally has lower miss rates than random and FIFO policies, and performs similarly to 2-random, especially in larger caches.

3. Hierarchical vs. Single Caches: Results differ between hierarchical caches (multiple levels) and single-level caches. LRU tends to do better in smaller caches, while 2-random outperforms LRU in larger caches.

4. Pseudo Policies: Implementing pseudo-LRU policies can save resources. Pseudo 2-random and pseudo 3-random can yield results close to true 2-random with less complexity.

5. Future Exploration: The text suggests exploring different eviction policies at various cache levels and applying this research to other types of caches beyond CPUs.

Overall, the findings indicate that while LRU is effective for smaller caches, 2-random may be more advantageous for larger caches, particularly when implemented with pseudo approaches to reduce complexity.

A new laundry-folding robot called Lume, created by Stanford researcher Aaron Tan, has gained significant attention online. The robot, disguised as a pair of bedside lamps, uses robotic arms to fold laundry quietly. In a recent teaser video, Lume garnered 3.8 million views in just 48 hours, sparking curiosity and comments about its functionality.

Tan, who has a Ph.D. in robotics, designed Lume to blend seamlessly into home environments as "ambient robotics," meaning it works in the background without being intrusive. Users can activate Lume via voice commands or an app, and it will fold laundry once it's placed on a bed.

Tan's inspiration for Lume came from the movie "Beauty and the Beast," aiming for a design that is both functional and aesthetically pleasing. The robot currently has a prototype and is expected to be available for pre-order in 2026, priced under $2,000.

While there are discussions about expanding its functionality, Tan emphasizes that Lume is designed solely for folding laundry and will avoid any human interaction for safety reasons. The overall goal is to create a tool for household chores rather than a humanoid robot.

The article discusses an experiment where the author tried to live for a day using only IPv6, a newer internet protocol. Despite being established for 25 years, IPv6 adoption has been slow, and many systems still rely on the older IPv4. The author found that while some services like Gmail worked well with IPv6, many daily tasks became difficult because most applications and devices still depend on IPv4.

To conduct the experiment, the author set up a network that only used IPv6, but encountered challenges as many devices and programs were not fully compatible. They noted that their smartphone had to rely on both IPv4 and IPv6 due to how cellular networks are set up. In conclusion, despite some support for IPv6, the overall experience highlighted the ongoing struggle for complete transition to the new protocol.

Summary of Linear Types in Programming

Linear types are a concept in type theory linked to linear logic, introduced by Jean-Yves Girard. They have significant applications in computer science and programming. The key points about linear types include:

1. Main Operators:

   • A⊗B: Represents two independent values that can be used in any order.
   • A⊕B: Represents a choice between A or B, requiring readiness for either.
   • A&B: Offers a choice between A or B, with the consumer deciding.
   • ⅋A⅋B: Represents interdependent values where the producer chooses the order.

2. Usage in Programming:

   • Linear types ensure that values can only be used once, which helps manage resources and avoid issues like garbage collection.
   • They can model scenarios where using a resource changes its state, like a vending machine that consumes a dollar for an item.

3. Applications:

   • Memory Management: By preventing duplication, linear types help determine how long values need to exist, eliminating the need for garbage collection.
   • Concurrency: They allow the specification of operation sequences, which helps avoid errors and deadlocks in concurrent programming.

4. Examples in Languages:

   • While no mainstream language fully implements linear types, languages like Haskell and Rust incorporate aspects of them.
   • Rust uses an affine type system, allowing for deletion but not duplication of values, and has unique-reference types that manage state mutation.

5. Session Types:

   • These are a variant of linear types used for defining protocols in communications, ensuring the correct order of message exchanges.

Overall, linear types provide a way to manage resources and control state changes in programming, offering a powerful tool for developers.

The paper introduces a new approach to deep learning by proposing the ⵟ -product (Yat-product), a novel neural operator that integrates two key concepts: vector alignment and spatial proximity. Traditional deep learning relies on the dot product, which combines magnitude and direction, limiting the model's ability to express complex geometric relationships. The ⵟ -product overcomes this limitation by using a formula inspired by physical laws, allowing for a more nuanced assessment of similarity between vectors without needing separate activation or normalization layers.

This leads to the development of Neural-Matter Networks (NMNs), a new class of neural architectures that utilize the ⵟ -product. These networks aim to maintain geometric fidelity and interpretability in their representations. The research shows that NMNs perform competitively on tasks like image classification and language modeling while providing clearer and more meaningful model outputs.

Key contributions of this work include:

1. The introduction of the ⵟ -product, which combines alignment and proximity in one computation.
2. The design of Neural-Matter Networks that inherently incorporate non-linearity and preserve input structure.
3. An open-source commitment to share the code and models for further research.

Overall, the paper advocates for a shift in neural computation design, grounding it in geometric and physical principles to enhance efficiency, robustness, and interpretability in deep learning models.

Summary of the CalyxOS Community Letter

The CalyxOS community is facing changes due to the departures of key members. Nicholas Merrill, the founder of Calyx Institute, is leaving to pursue other projects, and Chirayu Desai, the Tech Lead for CalyxOS, has also stepped down. Both have made significant contributions to the organization, and their absence will be felt.

Ellen McDermott will serve as the Interim Executive Director while the CalyxOS team works to maintain focus and continuity. The mission of defending digital privacy and improving connectivity remains unchanged.

During this transition, the team will enhance transparency and security, upgrade technology, stabilize updates for supported devices, and update documentation. However, it may take four to six months to achieve these goals, which means current CalyxOS users will not receive security updates during this time.

As a result, new installations of CalyxOS are temporarily paused, and users are advised that they will not have the latest security patches. Instructions for backing up devices will be provided by August 6.

The team will keep the community updated on progress and welcomes feedback. They appreciate the community's support and look forward to future collaboration.

The article discusses the benefits of having roommates, even for those who can afford to live alone. The author, Gillian Morris, reflects on her experience of subletting a one-bedroom apartment in New York City after living communally for over a decade. Initially, she enjoyed the privacy and freedom of living alone but quickly faced challenges, such as managing grocery shopping, cooking, and the inefficiency of a one-person kitchen.

She missed the social aspects of communal living, including spontaneous meals, shared experiences, and the support of friends during tough times. Despite the appeal of solitude, she found it isolating and less enjoyable than living with others. Ultimately, she concluded that, for her, having roommates brought more joy and fulfillment than living alone. She encourages others to consider the benefits of shared living, especially as they grow older and may have better experiences with roommates.

A few months ago, @andrewrn attempted to create a Wordle-like website focused on order-of-magnitude thinking, but it turned out to be complicated and confusing. Recently, I revisited this concept and developed a simpler site that presents a new Fermi estimation question each day. Examples of questions include: "How many new cars were sold in the US in 2024?" and "How many chickens are slaughtered for meat each year?" To win, players must guess within 20% of the correct answer, with a maximum of 6 attempts and feedback on whether their guess is too high or low. Fermi questions help improve numerical skills and understanding of large differences, as highlighted by Douglas Hofstadter in his essay about the dangers of innumeracy.

People can use their background knowledge to make inferences and predictions in new situations. This text explores a theory that suggests people create customized mental models for these situations by combining different types of information. The authors propose a system called "Model Synthesis Architecture" (MSA) that uses language models to gather relevant information and create coherent world models. They tested this MSA using a dataset that involves sports scenarios, which required reasoning about new causal relationships and using extensive background knowledge. The results showed that the MSA performed better than simpler language models in mimicking human reasoning. This indicates that MSAs can effectively model how people think and reason in complex, open-ended situations.

A group of contributors, including @AaronBallman, @shafik, @Endill, and @cor3ntin, is proposing a new approach to enhance the safety and security of C and C++ programs. This is important because while standards bodies are working on improvements, actual implementations like Clang must take the lead in ensuring code quality.

Currently, Clang has many safety features, but they are not well organized or documented, making them hard for users to access. The proposal aims to unify these features into a user-friendly "hardened mode."

Key proposals include:

• Setting user expectations that some changes may break existing code to improve safety.
• Creating a mode similar to GCC's -fhardened but tailored for Clang, acknowledging differences between the two compilers.
• Enabling various flags automatically to enhance code safety without users needing to configure them manually.

Several options for implementing this hardened mode are being discussed:

1. Configuration File: Users can set the mode easily with a config file.
2. New Driver Mode: A distinct compiler mode that changes user expectations but may complicate integration with existing tools.
3. Orthogonal Flags: Separate flags for different categories of settings, allowing users to choose what they want individually.
4. Single Flag: A single command (e.g., -fhardened) that enables all protections, though this could create compatibility issues with GCC.

The community is being asked for feedback on how to proceed with this proposal before a detailed plan is developed.

Summary: The Big Oops in Type Systems

The critique of type systems, originally focused on object-oriented programming (OOP), also applies to functional programming (FP). Type systems are often ranked by their ability to represent complex business models, with languages like Haskell and Idris at the top, and Python and JavaScript at the bottom. Proponents of static typing claim that better type systems can reduce the need for testing by proving certain software properties. However, encoding real-world business domains into rigid type structures often leads to complications and requires costly refactoring when business needs change.

There is a distinction between how data is processed technically and how it is understood contextually within a business. Traditional type systems may enforce strict categories that fail to reflect the messy, overlapping realities of business logic. As business requirements evolve, the rigidity of type hierarchies can create problems, making it difficult for developers to adapt to new rules.

While Haskell-style type systems can provide clarity, they often lead to overly complex structures that don't align with how domain experts think about their work. For example, rules that seem simple can quickly complicate the type definitions, resulting in a convoluted system that is hard to maintain.

Clojure offers an alternative approach by focusing on data modeling rather than strict type hierarchies. This allows for greater flexibility in handling business logic, enabling developers to modify rules without needing to overhaul the type system. The emphasis is on creating transformation functions that are easier for domain experts to understand and verify.

Ultimately, the article argues that we should not reject type systems entirely but recognize their appropriate use. Strong typing is beneficial for low-level concerns, while business logic requires more flexible approaches. The goal is to balance reliability in critical areas with the flexibility needed in constantly changing business environments. By using the right tools at the right level of abstraction, we can effectively manage the complexities of both technology and business.

Summary of "The Math Is Haunted"

The author discusses Lean, a programming language primarily used by mathematicians to formalize mathematical concepts. Lean allows mathematicians to represent math as code, making knowledge verifiable and shareable, similar to software development.

To illustrate Lean, the author presents a simple theorem stating that 2 equals 2, demonstrating how to write proofs using tactics like rfl (reflexivity) and sorry (a placeholder for unfinished proofs). The tactics help close goals in proofs, with rfl confirming equalities.

The author then explores more complex and humorous proofs, such as asserting that 2 equals 3 using an axiom called "math_is_haunted". This axiom shows how one can manipulate proofs, even leading to absurd conclusions like 2 + 2 equaling 6 by rewriting expressions based on the axiom.

The discussion highlights the importance of sound axioms in mathematics. If the axioms are flawed, as with the "haunted" axiom, it can lead to contradictions. The author concludes that working with a proof checker like Lean can be fun and enlightening, encouraging readers to explore Lean further through various resources.

The text also mentions the efforts to formalize Fermat’s Last Theorem in Lean, emphasizing the ongoing journey of making complex mathematical proofs rigorous and sound. Overall, the author invites curiosity about Lean and its potential for mathematical exploration.

In this article, Stefano Marinelli discusses how to set up an effective backup system using FreeBSD. Key points include:

1. Backup Server Choice: The author prefers FreeBSD for backup servers due to its versatility and reliability, using either professional services or personal control over storage.

2. Network Configuration: Both IPv4 and IPv6 are utilized for server connections. The author uses NAT and port forwarding for IPv4 and assigns public IPv6 addresses to virtual machines (VMs) and jails.

3. Backup Strategy: Marinelli emphasizes having both local and remote backups. Local servers allow easy access, while remote servers ensure availability in case of local failures. It's crucial that these backups are stored in different data centers to prevent loss during disasters.

4. Disk Redundancy: The author advocates for RAID setups to protect backup data, as data recovery is critical.

5. Security Measures: Backup servers should be hardened and encrypted. The author uses GELI and ZFS encryption to secure data on backup disks, ensuring that stolen disks remain useless without the encryption keys.

6. Software Tools: Various backup tools are recommended, including:

   • zfs-autobackup for FreeBSD servers using ZFS.
   • BorgBackup for other OS types, emphasizing its reliability.

7. Setup Instructions: The article outlines how to configure FreeBSD jails and VMs for isolated backup environments, stressing the importance of secure configurations.

8. Proxmox Backup Server: Marinelli discusses setting up Proxmox Backup Server within a VM, using Minio for data storage.

9. Local Snapshots: The author highlights the use of ZFS snapshots to protect against ransomware and other data loss threats.

10. Final Thoughts: The article concludes with a reminder of the importance of diligent backup practices and monitoring to ensure data security.

This guide provides a comprehensive overview of building a secure and efficient backup system using FreeBSD, emphasizing the importance of redundancy, security, and reliability in data management.
