3. Superconducting Microprocessors? Turns Out They’re Ultra-Efficient (2021)
Total comment counts : 16
Summary
Researchers in Japan have developed a superconducting microprocessor, called MANA, which operates at ultra-low temperatures and has zero electrical resistance. The microprocessor is composed of superconducting niobium and utilizes adiabatic quantum-flux-parametrons (AQFPs) to minimize energy consumption. The MANA microprocessor has the potential to significantly improve energy efficiency in computing, although current designs require cryogenic cooling systems. Despite the cooling overhead, the AQFPs are approximately 80 times more energy-efficient than traditional semiconductor electronics. The researchers believe that with further advancements in design methodology and experimental setup, clock frequencies of 5-10 GHz can be achieved. The superconducting microprocessor is best suited for large-scale computing infrastructures like data centers and supercomputers.
Top 1 Comment Summary
This article discusses a research group in Japan that aims to create a superconductor microprocessor that operates adiabatically, meaning that no energy is gained or lost during the computing process. The article also mentions a law of information theory known as Landauer’s principle, which suggests that expending energy is necessary for computation. However, there appears to be some dispute regarding this principle.

4. Call of Duty: Warzone Caldera Data Set for Academic Use
Total comment counts : 9
Summary
Activision has released an open-source data set featuring the Caldera map from Call of Duty: Warzone for non-commercial use. The data set includes the geometry of Caldera as well as anonymized time samples showing player movement on the map. This initiative aims to promote innovation and growth in the gaming industry, particularly in AI learning and game development. The release of Caldera as an open-source asset allows developers, educators, and researchers to use it for training, demonstrations, and experimentation. It also contributes to the advancement of artificial intelligence by providing a diverse environment for training AI models. Additionally, Activision’s technology teams believe that open-source assets like Caldera can drive the development of robust authoring tools and facilitate the creation of immersive experiences. The Caldera Data Set is one of the largest open data set releases from the gaming industry in terms of geometry complexity and instance counts. It includes approximately 4 GB of geometry data, consisting of over five million meshes, 28 million primitives, and more than one billion point instances. Alongside the geometry, the data set also includes in-game character pathing and time samples showcasing player behavior on the map. Caldera was chosen as the map for this release because it represents the scale and complexity of Activision’s current design philosophy.

5. Creativity fundamentally comes from memorization?
Total comment counts : 56
Summary
The author discusses the relationship between creativity and memorization, arguing that memorization plays a crucial role in fostering creativity. They believe that creativity relies on internalized concepts and patterns, which are acquired through memorization. The author shares their personal experience growing up with Indian and American education systems, highlighting the importance of drilling and memorization in achieving academic success. They assert that memorization is not separate from understanding but rather a form of subconscious pattern recognition. By internalizing heuristics and memorizing knowledge, individuals can free up cognitive resources to focus on higher-level problem-solving and creativity. The author suggests that systems and memorization enable creativity rather than stifle it, as they provide a foundation for exploring novel ideas and violating expectations. They also mention the benefits of their own learning system in quickly acquiring new skills and suggest that becoming autonomous in multiple areas can enhance creativity.
Top 1 Comment Summary
This article rejects the idea that memorization should be defined as anything that leads to something being retained in memory. The author argues that memorization should refer to the use of language to drill exposure to an abstract representation of a concept, which is not an effective way of absorbing the concept itself. The author believes that experts often fail to understand that learners need meaningful experiences to understand concepts, rather than just drilling vocabulary flashcards. While drilling can be helpful in certain areas, it is only a small part of learning. The author suggests that deliberate practice or “putting in the reps” is a more purposeful and effective approach to learning than traditional memorization techniques.
Top 2 Comment Summary
The article argues that rote memorization is not necessary or sufficient for internalizing concepts. It claims that systematic memorization cannot teach taste and is often associated with awkward, tasteless art. Memorization is also said to be ineffective for developing tacit knowledge, especially in creative fields like programming. The author suggests that memorization may be a small component of developing expertise, with realistic practice and mentorship being more important. Additionally, memorization is criticized for its time-consuming and dull nature, which can kill intrinsic motivation for learning. The author advocates for focusing on contextual practice instead of memorization.
6. Rustgo: Calling Rust from Go with near-zero overhead (2017)
Total comment counts : 11
Summary
The article discusses the idea of calling Rust code from Go in order to replace assembly code. The author explores the challenges of writing and reviewing assembly code, and the potential benefits of using a higher-level language like Rust. They mention that Go has a Foreign Function Interface (FFI) called cgo, which allows Go programs to call C functions. However, the performance cost of each cgo call is too high for small hot functions. The article proposes using Rust code that is as constrained as assembly and calling it directly from Go, with a thin layer of glue. The author explains the process of linking a Go program with a Rust archive and suggests finding a way to do this without patching the compiler.
Top 1 Comment Summary
The author is discussing the challenges of linker wrangling in the next version of the Go/Rust linker. They wonder if it would have been easier to disassemble the Rust binary and convert it into Go assembly. However, this would require a complex program to process the binary back into assembler. Alternatively, they suggest using the Rust compiler to output assembly and then processing it into Go assembly. They believe that using Go assembly would be more convenient, as it would avoid linker issues, be more likely to survive upgrades, and be cross-platform.
Top 2 Comment Summary
The article discusses the author’s experience while transitioning from Go to Rust. They mention that they decided against using Rust for a cross-platform binary due to the complexities of raw assembly. However, they acknowledge that the article is still interesting and highlight the need for better literature on Go/Rust interoperability.

This article discusses AUTOVON switching centers, which were strategically located and hardened telephone central offices in the US. There were at least 38 of these centers, designed to survive a nuclear war, by having redundant links between switches. The technology used in these centers was Western Electric’s 1ESS, which allowed clear conference calls without feedback. The 1ESS system was bulky and consisted of a pair of large mainframe computers running a switch fabric. The switch fabric used analog and electromechanical components, making the installations large despite not having a large number of lines.
9. Building static binaries with Go on Linux
Total comment counts : 10
Summary
The article discusses how Go can produce statically-linked binaries on Unix systems. It provides examples of how to determine whether a binary is statically or dynamically linked using tools such as “file”, “ldd”, and “nm”. It explains that certain functionality in the Go standard library relies on the system’s libc for DNS lookups and user/group ID lookups, and demonstrates how to use the pure Go implementations of these functionalities to produce statically-linked binaries. The article also covers how C code and the use of cgo can result in dynamically-linked binaries, and suggests using the musl libc implementation to statically link these binaries.
