Postgres: Powering Scalable, Observable Durable Workflows

This blog post delves into the technical reasons behind DBOS's choice of PostgreSQL as the metadata store for their durable workflow library. PostgreSQL's concurrency control, specifically its locking clauses, solves contention issues in database-backed queues, enabling scalability to tens of thousands of workflows per second. Its relational data model and secondary indexes simplify the development of observability tooling for real-time monitoring and visualization of workflow execution. Furthermore, PostgreSQL transactions guarantee exactly-once execution semantics for database operations, preventing duplication. PostgreSQL's features make it ideal for building robust and performant durable workflow libraries.

Lisp1 vs. Lisp2: The Great Namespace Debate

2025-08-09

This technical report delves into the advantages and disadvantages of separating function and value namespaces in Lisp. Lisp1 uses a single namespace, while Lisp2 separates them. The authors analyze the trade-offs in notational simplicity, referential clarity, compiler complexity, higher-order functions, macros, and space/time efficiency. While Lisp1 offers advantages in conciseness and functional programming style, Lisp2 excels in macro usage and mitigating naming conflicts. Ultimately, the report concludes that the status quo (Lisp2) is preferable for Common Lisp.

Volt Boot: Exploiting Power Domain Isolation to Bypass On-Chip SRAM Security

2025-07-29

This paper introduces Volt Boot, a novel attack that leverages power domain isolation in modern Systems-on-a-Chip (SoCs) to compromise the security of sensitive information stored in on-chip SRAM. Traditional cold boot attacks are ineffective against on-chip SRAM, but Volt Boot achieves cross-power-cycle SRAM data retention by maintaining the voltage of the target memory domain during system reset. Experiments on three commercially available Cortex-A processors successfully extracted data from caches, CPU registers, and iRAM, demonstrating the attack's effectiveness. The research highlights new security challenges for systems relying on on-chip computation and proposes countermeasures such as eliminating power domain isolation, purging residual memory, resetting SRAM at startup, and enforcing TrustZone support.

Small Town Baseball: A Fight for the American Soul

Journalist Will Bardenwerper's new book, *Homestand: Small Town Baseball and the Fight for the Soul of America*, explores the consequences of Major League Baseball cutting 40 affiliated minor league teams—each costing roughly the equivalent of a single major leaguer's salary. Following the Batavia Muckdogs in New York, Bardenwerper highlights how affordable and accessible minor league baseball fosters community in working-class towns. He celebrates the resilience of the Muckdogs' fans and owners who revived the team after its initial elimination. The book emphasizes the unique intimacy and affordability of minor league games, fostering strong community bonds and intergenerational connections rarely seen elsewhere in modern American life. Bardenwerper argues that the cuts represent a loss of vital community values.

From Animal 'Factories' to Synthetic Biology: A Revolution in Biopharming

Historically, many medicines and materials relied on animal extraction, such as antivenom from horse blood, endotoxin detection from horseshoe crab blood, and silk from silkworms. This article traces the journey from ancient Phoenicians using snails to extract Tyrian purple dye to the modern use of biotechnology to synthesize insulin, antibodies, and vaccines. While synthetic biology technologies can now replace many animal-derived products, some areas still rely on animals due to regulatory lag, molecular complexity, and challenges in scaling production, such as influenza vaccine production. The article highlights the enormous potential of synthetic biology to improve efficiency and reduce animal use, but also reminds us of the importance of protecting biodiversity, as the development of biotechnology also relies on exploration and utilization of the natural world.

Were Neanderthals Cold-Adapted or Just Highly Adaptable? Ribcage Reconstruction Offers Clues

A new study virtually reconstructs a Neanderthal ribcage from Shanidar Cave in Iraq. The results reveal a unique "bell-shaped" Neanderthal thorax, distinct from modern humans and closer to those adapted to cold climates. However, this doesn't imply exclusive cold-adaptation, as Shanidar 3 and Kebara 2 Neanderthals lived in relatively mild climates. The study suggests Neanderthal body builds were adaptable to various climate types, not just cold ones.

Robotics vs. AI: Debunking Complexity Misconceptions

2025-01-11

This article tackles common misconceptions surrounding the complexities of robotics versus AI. The author argues that people often conflate the two fields, assuming advancements in AI directly translate to breakthroughs in robotics. However, the core challenge in robotics lies in the intricate nature of sensorimotor control, far more difficult than commonly perceived. This aligns with Moravec's Paradox: low-level sensorimotor skills are harder to replicate than high-level reasoning. The author further explains how current AI solutions rely on immense computing power and massive datasets, conditions difficult to replicate in robotics. Hardware limitations, data bottlenecks, and model speed are also discussed, alongside a forward-looking perspective on future robotics development.

Visualizing Complex Eigenvalues of Real Matrices with 3D Plots

2025-07-21

This article explores the 3D plot of the equation x²+(y+zi)²=1 (where x, y, z are real numbers and i is the imaginary unit), revealing a circle and a hyperbola. Separating the equation into real and imaginary parts yields two cases: when y=0, x²-z²=1 (a hyperbola); when z=0, x²+y²=1 (a unit circle). This visualization offers insights into the behavior of complex eigenvalues of real matrices that depend on a real parameter. Two examples of 2x2 matrices are provided, demonstrating how this method analyzes eigenvalues. The article concludes by suggesting that this approach can be extended to other 2x2 matrices dependent on a single real parameter.

Uranus: Not as Cold and Dead as We Thought

A new study reveals Uranus possesses internal heat, contradicting previous observations. Researchers found Uranus radiates more heat than it receives from the sun, indicating a slow release of residual heat from its formation. This discovery enhances our understanding of Uranus's origin and evolution, informing future exploration missions and potentially providing insights into Earth's climate and atmospheric processes. While Uranus's internal heat is weaker than other gas giants, its energy levels fluctuate with its lengthy 20-year seasons, likely due to its eccentric orbit and tilted spin. This research significantly supports NASA's planned Uranus mission and offers novel approaches to studying radiant energy in other planets, both within and beyond our solar system.

Iberian Blackout: Was It Renewables' Fault?

Iberian Blackout: Was It Renewables' Fault?

A massive blackout hit Spain and Portugal in April 2024, affecting nearly 60 million people. While official investigations are ongoing, academics suggest several potential causes, including power plants sending excessively high voltage (overvoltages) to the transmission grid, and uneven reactive power distribution due to the distributed generation model of renewable energy (solar and wind). Traditional power plants provide inertia, stabilizing grid frequency, a characteristic lacking in renewables. The overvoltage issue highlights reactive power management, requiring adjustments to grid management rules to incentivize renewable energy plants to participate in reactive power balancing. Spain and Portugal's low interconnection capacity with neighboring countries also contributed to the blackout's widespread impact and duration. Future improvements in grid management rules, increased interconnection capacity, added energy storage, and AI-assisted grid operation are vital to prevent similar events.
