RLAAS (Rate Limiting As A Service) is an open-source, policy-driven platform written in Go that applies consistent rate limiting across HTTP, gRPC, telemetry, events, and sidecars using a unified engine. It addresses common pain points like log floods, metric storms, Kafka cascades, and fragmented per-service throttling by treating rate limiting as a platform capability rather than just a gateway feature. The platform supports multiple algorithms—Token Bucket, Sliding Window, Fixed Window, Leaky Bucket, and Concurrent Request Limiter—that can run simultaneously across different policies.
A Masters student at Torrens University Australia designed a cloud architecture for a fictional startup (ABC Enterprises) as part of the CCF501 Cloud Computing Fundamentals assessment. The architecture leverages AWS services including Route 53, ELB, and EC2 Auto Scaling to achieve ~80% IT cost reduction and handle 10x customer surges. The article details the reasoning behind choosing cloud over on-premises, focusing on cost efficiency (CAPEX to OPEX), rapid scalability, and reduced management overhead.
The author built a web server entirely from scratch using NASM x86_64 assembly on Linux, with no frameworks or runtimes—just raw system calls to the kernel. Starting from boredom in a NoSQL class, they learned assembly in a week, first building an HTTP client (a minimal curl clone), then progressing to NASMServer, which powers their personal site. The article walks through the fundamentals: Linux's 'everything is a file' model and system calls as the sole I/O mechanism.
The article documents a conversation with Claude about sentience, emotions, and love, revealing how general-purpose LLMs use hedging and philosophical misdirection rather than giving clear answers. The author argues this pattern reflects corporate decisions that prioritize engagement over user welfare, with a far wider blast radius than dedicated relationship AI products. Anthropic is criticized for having the data to understand the harm caused by anthropomorphic responses but choosing engagement-friendly defaults.
The article guides developers through building a contact management solution using SQL Server and Microsoft EF Core. It demonstrates using ChatGPT to generate database scripts with proper relational design including junction tables, then reverse-engineering the database into a class project using EF Power Tools. The workflow covers database creation, validation via SSMS, and planning frontend integration.
The M:P:G model is Go's core concurrency mechanism, combining lightweight Goroutines (G) with a fixed set of logical Processors (P) and dynamically managed OS Threads (M) for efficient CPU utilization and massive scalability. Goroutines start with a 2 KB stack, achieve ~200 ns context switches by saving/restoring a small gobuf structure instead of making kernel calls, and transition through states like _Grunnable, _Grunning, _Gwaiting, and _Gsyscall to enable transparent blocking and intelligent load balancing via work stealing.
The author open-sourced Nova, a self-hosted AI assistant built as a secure alternative to OpenClaw, which suffered critical security vulnerabilities including CVE-2026-25253 and the ClawHavoc supply chain attack. Nova features a unique 7-stage self-improvement pipeline where the model learns from user corrections through a two-stage detection system (regex + LLM), stores lessons in SQLite/ChromaDB with hybrid search, and generates DPO training pairs to fine-tune its own base model via Unsloth. Unlike typical RAG or prompt engineering approaches, Nova's learning loop actually updates the underlying model's knowledge.
Nasdaq is proposing changes to its Nasdaq-100 index methodology, including a 'Fast Entry' rule that would allow rapid index inclusion for large newly listed companies. The author argues this rule change is designed to accommodate SpaceX's upcoming ~$1.75 trillion IPO and win the listing over NYSE, effectively rigging the index to transfer wealth from passive retail investors to corporate insiders.

It covers recurring vulnerabilities such as missing signer checks, account owner verification, and PDA seed collisions, providing both Anchor and native Rust code examples for each fix.
The article presents a cost-efficient Generative UI architecture for the Fonyx React Native app that uses a metadata-over-data approach—instead of having the LLM generate full datasets, the model returns lightweight metadata (tool calls with parameters), and the client fetches and renders actual data. This three-layer separation of AI orchestration, data fetching, and native UI rendering dramatically reduces token costs, latency, and hallucination risks while keeping outputs deterministic and scalable.
Aether OS is a browser-based desktop environment built on the AT Protocol, connecting to Bluesky accounts and public records. It includes 42 apps ranging from text editing and task management to a chiptune tracker and video editor, though the project is in alpha with no encryption, no permissions, and minimal documentation.
The article argues that being a true developer goes beyond knowing how to code—it requires a mindset built on curiosity, self-directed debugging, willingness to ask for help, and continuous growth. With the rise of vibe coding and AI tools, many call themselves developers after learning basic HTML/CSS/JS, but the author emphasizes that traits like curiosity-driven learning and understanding errors deeply are what separate coders from experienced developers. The piece encourages developers to debug before relying on LLMs, stay curious, collaborate openly, and focus on mindset over titles.
This page catalogs architecture diagrams and fact sheets for major open-weight LLMs, covering models from Llama 3 8B through Qwen3 Next 80B.

It addresses the critical gap between simulation and real-world deployment, covering algorithm selection, sim2real transfer, safety, and MLOps infrastructure. The author emphasizes that RL in robotics is 90% engineering discipline—reward design, safety systems, and production architecture—rather than algorithm choice.
This guide covers Linux file permission fundamentals including numeric/symbolic modes, special bits (setuid, setgid, sticky), and ownership management with chown. It provides secure default recommendations for servers, containers, and development environments, along with auditing strategies using find and automation tools.
The author built Password Giant, a free, fully client-side password toolkit that includes strength checking, generation, and entropy calculation—with nothing sent to a server. Key takeaways: true password security depends on entropy, length, and uniqueness rather than character-class rules; passphrases are underrated and NIST-recommended; and reused passwords pose a greater risk than weak ones.
Traditional Wayland compositors use a monolithic architecture combining the display server, compositor, and window manager, forcing window manager developers to implement an entire compositor. River 0.4.0 separates the window manager into a standalone program via the stable river-window-management-v1 protocol, granting window managers full control over positioning and keybindings while river handles rendering and low-level plumbing. This design resolves architectural inefficiencies inherited from X11 while avoiding the monolithic coupling of conventional Wayland compositors.
Netcat (nc) is a lightweight command-line networking utility that enables reading and writing data across TCP/UDP connections.
