Glitch to Shut Down Core App Hosting in 2025

Glitch, a coding platform for sharing and remixing projects, announced it will cease its core feature—hosting web apps—on July 8th, 2025. This means users will no longer be able to host projects on Glitch, and user profiles will be closed. While CEO Anil Dash hasn't confirmed a complete shutdown, the move casts doubt on the platform's future. Users will have until the end of 2025 to download their code and access their projects; Glitch is also working on a project subdomain redirection feature. The change is attributed to increased maintenance costs and malicious activity, leaving Glitch's future uncertain.

Sweden Rethinks Tech-Heavy Education, Brings Back Books and Pencils

Concerns over declining basic skills among Swedish students have prompted a shift in the country's digital education strategy. Years of emphasizing tablets and digital tools in schools have come under scrutiny following a drop in reading scores. In response, the government is increasing investment in physical books and encouraging a return to traditional teaching methods like handwriting practice and quiet reading time. While some experts support this back-to-basics approach, others argue it's an overreaction, emphasizing that technology is just one factor in a complex educational ecosystem.

Lockheed Martin's QuadStar Missile: A Stinger Successor?

Lockheed Martin is developing the QuadStar surface-to-air missile as a replacement for the aging Stinger. Leveraging technology from its Miniature Hit-to-Kill (MHTK) interceptor, particularly advanced seeker technology, QuadStar boasts a more aerodynamically efficient design. Aiming to maintain the same form factor as the Stinger while offering increased range and lethality, it's designed to effectively engage various drones and manned aircraft. QuadStar features a modular, open-architecture design for easy integration of new capabilities and utilizes AI and machine learning for improved target recognition and tracking. Its new Command Launch Assembly (CLA) significantly enhances targeting capabilities. While competing against Raytheon, QuadStar's low cost, high performance, and ease of manufacturing position it as a strong contender to become the US Army's next-generation short-range interceptor in the coming years.

Feast, Milvus, and Docling: A Quickstart for RAG

This project demonstrates building a Retrieval-Augmented Generation (RAG) application using Feast. It expands on a basic RAG demo, showcasing how to transform PDFs into LLM-ready text data with Docling, use Milvus as a vector database for embedding storage and retrieval, and perform PDF transformations with Docling during ingestion. Key features demonstrated include online feature retrieval, declarative feature definitions, vector search, handling structured and unstructured context, and versioning/reusability. The project includes sample data, a Python file defining Feast feature views and entities, a YAML file configuring offline and online stores, and two main notebooks: one for PDF text extraction and Parquet storage using Docling, and another for ingesting and managing data with Feast.

Collaborative Text Editing Without CRDTs or OT

2025-05-21

This blog post presents a novel approach to collaborative text editing that avoids the complexities of Conflict-free Replicated Data Types (CRDTs) and Operational Transformation (OT). The core idea is to assign globally unique IDs to each character and use "insert after" operations. The server updates its state literally based on these operations, while clients employ server reconciliation for optimistic local updates. This approach is simpler and more flexible than CRDT/OT, allowing for customized operations and features like handling rich text and access controls. An accompanying npm library, Articulated, aids in implementation.

AI-Generated Website: An Experiment in Skill vs. Knowledge

2024-12-31

Security researcher Nicholas Carlini conducted a twelve-day experiment: rewriting his website homepage and bio daily using a different language model. He found that while models excelled at generating visually stunning webpages, they faltered significantly in factual accuracy. For example, the o1-mini model generated a webpage with 43 statements; 32 were completely false, 9 had major errors, and only 2 were factually correct. This highlights the vast discrepancy between "skill" (generating webpages) and "knowledge" (factual accuracy) in LLMs, underscoring the need for caution when relying on AI-generated content.

GPS Under Siege: A Growing Threat and the Need for Urgent Action

2025-05-21

GPS is facing a significant increase in jamming and spoofing attacks, with as many as 700 daily incidents reported in 2024. This vulnerability, stemming from weak signals and lack of encryption, poses a serious threat to various sectors, including aviation, finance, and power grids. The article details a recent deadly incident linked to GPS interference. Solutions explored include easing export controls on advanced anti-jamming antennas, partnering with Europe's Galileo system, enhancing GPS signal encryption, and implementing a global augmentation system (HARS). Alternative navigation technologies like eLoran, eDME, pseudolite networks, and MagNav are also discussed as potential backups to mitigate the risks of GPS disruption and future threats.

Challenging the CAP Theorem: A Partial Progress Conjecture Under Asynchrony

Challenging the CAP Theorem: A Partial Progress Conjecture Under Asynchrony

A new paper challenges the well-known CAP theorem. The authors conjecture that partial progress is possible under network partitions, meaning the system can remain responsive to a subset of clients and achieve non-zero throughput during failures. They present the design of their CASSANDRA consensus protocol, allowing partitioned replicas to order client requests, potentially offering a path to systems that are both consistent and available to some degree, even during partitions. This research offers a novel approach to building more robust distributed systems.

Pre-Columbian Venetian Beads Found in Arctic Alaska: Rewriting History?

Archaeologists have unearthed Venetian glass beads dating from 1397-1488 AD in pre-Columbian archaeological sites in Arctic Alaska. These beads, thousands of kilometers from their origin, predate Columbus's arrival in the Americas and provide compelling evidence of extensive trans-Eurasian trade networks reaching the Arctic before European maritime expansion. The discovery necessitates a reassessment of global trade and Indigenous connectivity, showcasing a far more interconnected world than previously imagined and challenging long-held assumptions about hemispheric isolation.
