RAG vs Agentic RAG

Agentic RAG goes beyond traditional RAG by adding the ability to reason, plan, and act. Instead of merely fetching and producing information, it autonomously determines what to retrieve, how to apply it, and when to adjust the context, enabling adaptive, goal-oriented systems that improve through continuous learning.

The $1 Trillion Illusion of AI Productivity

The software industry’s latest fantasy- that AI will deliver a tenfold leap in developer productivity- is now colliding with reality. As the author of the piece notes, the trillion-dollar AI sector still cannot produce reliable, production-grade code. Behind the flood of “breakthrough” announcements lies an epidemic of unmaintainable software, riddled with four recurring categories of error. The classical ones- false positives and false negatives- are joined by two new cognitive pathologies born from model mechanics themselves: entangled logic that turns architectures into spaghetti, and memory collisions that make unrelated functions misfire. What was once branded “hallucination” now looks less like quirk and more like structural failure. ...

Workflows are here to stay

Over the last year the workflows vs. agents debate has turned from a niche engineering question into something every product team seems to argue about. New tooling lowers the barrier to spin up an AI agent that can call tools in a loop, so leaders start asking whether they should rebuild processes around these agents, or stick with the safer structure of step-by-step workflows. The conversation heats up because both sides have real wins and real failure modes: agents feel magical when they solve fuzzy, open-ended tasks, but they can be slow, costly, and unpredictable at scale; workflows are efficient and auditable, but can feel rigid when the job needs exploration. That tension between flexibility and control is why this topic is hot and why teams keep getting stuck. ...

The A.I. era... follow the money

Bloomberg just published this fascinating map of the AI power network, showing how companies like NVIDIA, OpenAI, Microsoft, AMD, Oracle, and Intel are now intertwined through billions in deals, compute, and equity. It’s not just a supply chain anymore. It’s a feedback loop — where hardware, software, and capital keep feeding each other. NVIDIA sits at the center with a $4.5 trillion market cap, investing up to $100 billion in OpenAI, while selling GPUs to Oracle, AMD, xAI, and everyone else. OpenAI, in turn, signs a $300 billion cloud deal with Oracle, deploys 6 gigawatts of AMD GPUs, and gives AMD an option to buy 160 million OpenAI shares. Microsoft is still the connective tissue, part investor, part service provider, part enabler.

Time Between Disengagements

Time Between Disengagements is a concept I came across in a recent article from Gitpod, and it offered an interesting new way to think about AI’s role in software development. It compares the evolution of AI in engineering to the progression of self-driving cars—where the key metric is how long an autonomous system can operate before a human needs to step in. That simple but powerful analogy really clicked with me. It reframes how we should think about the future of AI-assisted development—not just in terms of raw capability, but in how independently and safely these systems can work. ...

Single-node Kubernetes, reimagined for edge and embedded

In Industrial IoT (IIoT) environments, devices often operate in remote, resource-scarce locations with intermittent connectivity and minimal hardware—conditions that demand lightweight, resilient software solutions. These edge deployments typically involve devices with less than 1GB of RAM, limited CPU power, and basic storage like SD cards, yet they must run reliably and autonomously. KubeSolo was designed precisely to meet these challenges. As a single-binary Kubernetes distribution, it’s carefully optimized to function efficiently in such constrained conditions, typically requiring only around 200MB of RAM. This makes KubeSolo an ideal solution for IIoT scenarios, delivering the power of Kubernetes at the edge without overwhelming the hardware. ...

Rethinking Microservices: What Startups Need to Know

Startups are often drawn to microservices with the promise of scalability and flexibility, but adopting them too early can backfire. Microservices introduce overhead—more infrastructure to manage, more complexity in deployments, and more effort in monitoring and debugging. For small teams moving quickly, these challenges can slow progress rather than support it. Early on, simplicity is a major advantage. Keeping your architecture lean—whether that’s a monolith or a tightly scoped service—allows you to move faster, iterate quickly, and focus on building the product. The key is not to avoid microservices altogether, but to recognize when the benefits truly outweigh the costs. Premature optimization can lead to a fragile setup that’s hard to maintain without delivering real value. ...

starting a grid back up from total collapse

The power grid is a vast and intricate system composed of generation units (like hydroelectric, thermal, and renewable energy plants), transmission lines, substations, transformers, and distribution networks that deliver electricity to homes and businesses. Orchestrating a black start across this interconnected web is a highly complex task—each component must be reactivated in a precise sequence to avoid overloads, instability, or cascading failures. Communication between grid operators, synchronization of frequency and voltage levels, and the gradual reintroduction of demand are all crucial elements. It’s a delicate dance that requires meticulous planning, real-time coordination, and robust contingency protocols. ...

The Motorola 68000 - a microprocessor ahead of its time

It was introduced in 1979 as a hybrid 16/32-bit CISC microprocessor, featuring a 24-bit flat address bus and a 16-bit data path. This design achieved over 1 MIPS of performance and outclassed contemporaries like the Intel 8086 in both speed and programmability. It rapidly became the engine behind landmark personal computers, such as the Apple Lisa and Macintosh, the Commodore Amiga, and the Atari ST, as well as gaming consoles like the Sega Genesis, due to its orthogonal instruction set, ample register file, and large unified memory space. Even after its discontinuation in 1996, the 68000’s architecture endured in embedded controllers, printers, and industrial systems, cementing a legacy that shaped subsequent CPU designs across the industry. ...

The Historical, Philosophical & Cultural Dimensions of Biometric Identity Verification

Biometric identity verification has deep historical, philosophical, and cultural roots that go beyond mere technology. From ancient philosophical inquiries into the nature of self to modern discussions on ethics and privacy, the concept of identity has been a subject of ongoing debate. Understanding these dimensions is crucial as biometrics become increasingly integrated into our daily lives, influencing societal norms, practices, and public perception. Contemporary perspectives on identity, influenced by thinkers like Foucault and Derrida, challenge fixed notions and emphasize its fluid and dynamic nature. As we navigate this evolving landscape, it’s essential to consider the ethical, legal, and social implications of biometric technologies, ensuring they align with our values and respect individual autonomy. ...
