Researchers in Spain have found that gamification is better at motivating software engineering students in performing QA tasks.

In the past, developers used the same API for both reads and writes on every case. This led to struggles with optimizing indexes on fields that were heavily queried. Valet key pattern, CQRS and search databases changed that.

A new paper investigates the intriguing possibility that gravitational forces from celestial bodies influence electrical activity and sap flow in trees.

This section examines NFT transaction networks using graph analysis, revealing decentralized structures and key influential nodes. Using metrics like reciprocity, k-core, and Article Rank, researchers identified strong connected components and trading influence in a network of 33,678 nodes and 425,246 transactions. Community clusters and collection-based dynamics were also observed, highlighting transactional patterns.

This section focuses on datasets and tools used for NFT transaction analysis on the Ethereum blockchain. Key datasets include 6.5M transactions from 4600 collections and time-series data for CryptoPunks. Visualization and graph modeling are performed using Neo4j, while LPPL models predict market trends. Simplified assumptions treat NFTs as homogeneous to streamline analysis.

This paper analyzes NFT transaction networks on Ethereum, focusing on growth, influential nodes, and market trends. Using graph analysis, researchers studied 7 collections from 2017-2021, identifying evolving network properties. The Logarithmic Periodic Power Law model predicts price trends for CryptoPunks, providing insights into NFT market dynamics and bubble behavior.

This section reviews prior work on blockchain graph analysis, focusing on ERC-20 and ERC-721 token networks and the use of the LPPL model for bubble prediction. Notable studies include Ethereum and Bitcoin transaction network analysis and early empirical work on NFTs. Few efforts explore NFT-specific bubble prediction, highlighting the novelty of this research in using LPPL for a single collection.

This methodology section explores NFT ownership trends and decentralized dynamics, revealing that most owners hold few tokens while some addresses own thousands, typically for financing or automated purchases. It identifies a Zipfian token distribution and highlights the unique roles and significance of different NFT collections, such as Ethereum Name Service (ENS).

Spring Cloud Gateway is a modern, non-blocking API gateway that offers significant improvements over its predecessor, Netflix Zuul. While transitioning from Zuul to Spring Cloud Gateway requires effort, it provides a more robust and scalable solution for microservice architectures

The article discusses the effective use of the @Transactional annotation in Spring, focusing on solving concurrency issues in microservices. The article emphasizes the need to understand and properly implement transactions in distributed systems to maintain data consistency and integrity

Bitcoin has good SoV and MoE functions. But it needs a semblance of intrinsic value. To maximize the SoV function, Bitcoin Maximalists have a term called 'Hodling', To maximize MoE, we need 'Hodl-Building'. We could Hodl now and Build now, or Build much later. Either way, Bitcoin will transform economics and the planet's tech landscape. It will also align AI towards maximum pro-human utility.

Dr Sabine’s new video is a logical tome, and I couldn’t quite grasp it. Meanwhile, I had a bone to pick with the way maths is taught in High Schools. It is mostly boring, generic, and useless, yet kids are interested in TikTok videos (geo-political squabbles be damned). Perhaps this is the reason why we aren't making much progress in high-level physics, nor much...
