Four important lessons about context engineering

Modern LLMs operate with context windows ranging from 8K to 200K+ tokens, with some models claiming even larger windows. However, several technical realities shape how we should think about context. ... Research has consistently shown that LLMs experience attention degradation in the middle portions of long contexts. Models perform best with information placed at the beginning or end of the context window. This isn’t a bug. It’s an artifact of how transformer architectures process sequences. ... Context length impacts latency and cost quadratically in many architectures. A 100K token context doesn’t cost 10x a 10K context, it can cost 100x in compute terms, even if providers don’t pass all costs to users. ... The most important insight: more context isn’t better context. In production systems, we’ve seen dramatic improvements by reducing context size and increasing relevance. ... LLMs respond better to structured context than unstructured dumps. XML tags, markdown headers, and clear delimiters help models parse and attend to the right information. ... Organize context by importance and relevance, not chronologically or alphabetically. Place critical information early and late in the context window. ... Each LLM call is stateless. This isn’t a limitation to overcome, but an architectural choice to embrace. Rather than trying to maintain massive conversation histories, implement smart context management


What Fuels AI Code Risks and How DevSecOps Can Secure Pipelines

AI-generated code refers to code snippets or entire functions produced by Machine Learning models trained on vast datasets. While these models can enhance developer productivity by providing quick solutions, they often lack the nuanced understanding of security implications inherent in manual coding practices. ... Establishing secure pipelines is the backbone of any resilient development strategy. When code flows rapidly from development to production, every step becomes a potential entry point for vulnerabilities. Without careful controls, even well-intentioned automation can allow flawed or insecure code to slip through, creating risks that may only surface once the application is live. A secure pipeline ensures that every commit, every integration, and every deployment undergo consistent security scrutiny, reducing the likelihood of breaches and protecting both organizational assets and user trust. Security in the pipeline begins at the earliest stages of development. By embedding continuous testing, teams can identify vulnerabilities before they propagate, identifying issues that traditional post-development checks often miss. This proactive approach allows security to move in tandem with development rather than trailing behind it, ensuring that speed does not come at the expense of safety. 


The New Role of Enterprise Architecture in the AI Era

Traditional architecture assumes predictability in which once the code has shipped, systems behave in a standard way. On the contrary, AI breaks that assumption completely, given that the machine learning models continuously change as data evolves and model performance keeps fluctuating as every new dataset gets added. ... Architecture isn’t just a phase in the AI era; rather it’s a continuous cycle that must operate across various interconnected stages that follow well-defined phases. This process starts with discovery, where the teams assess and identify AI opportunities that are directly linked to the business objectives. Engage early with business leadership to define clear outcomes. Next comes design, where architects create modular blueprints for data pipelines and model deployment by reusing the proven patterns. In the delivery phase, teams execute iteratively with governance built in from the onset. Ethics, compliance and observability should be baked into the workflows, not added later as afterthoughts. Finally, adaptation keeps the system learning. Models are monitored, retrained and optimized continuously, with feedback loops connecting system behavior back to business metrics and KPIs (key performance indicators). When architecture operates this way, it becomes a living ecosystem that learns, adapts and improves with every iteration.


Quenching Data Center Thirst for Power Now Is Solvable Problem

“Slowing data center growth or prohibiting grid connection is a short-sighted approach that embraces a scarcity mentality,” argued Wannie Park, CEO and founder of Pado AI, an energy management and AI orchestration company, in Malibu, Calif. “The explosive growth of AI and digital infrastructure is a massive engine for economic, scientific, and industrial progress,” he told TechNewsWorld. “The focus should not be on stifling this essential innovation, but on making data centers active, supportive participants in the energy ecosystem.” ... Planning for the full lifecycle of a data center’s power needs — from construction through long-term operations — is essential, he continued. This approach includes having solutions in place that can keep facilities operational during periods of limited grid availability, major weather events, or unexpected demand pressures, he said. ... The ITIF report also called for the United States to squeeze more power from the existing grid without negatively impacting customers, while also building new capacity. New technology can increase supply from existing transmission lines and generators, the report explained, which can bridge the transition to an expanded physical grid. On the demand side, it added, there is spare capacity, but not at peak times. It suggested that large users, such as data centers, be encouraged to shift their demand to off-peak periods, without damaging their customers. Grids do some of that already, it noted, but much more is needed.


A Waste(d) Opportunity: How can the UK utilize data center waste heat?

Walking into the data hall, you are struck by the heat resonating from the numerous server racks, each capable of handling up to 20kW of compute. However, rather than allowing this heat to dissipate into the atmosphere, the team at QMUL had another plan. Instead, in partnership with Schneider Electric, the university deployed a novel heat reuse system. ... Large water cylinders across campus act like thermal batteries, storing hot water overnight when compute needs are constant, but demand is low, then releasing it in the morning rush. As one project lead put it, there is “no mechanical rejection. All the heat we generate here is used. The gas boilers are off or dialed down - the computing heat takes over completely.” At full capacity, the data center could supply the equivalent of nearly 4 million ten-minute showers per year. ... Walking out, it’s easy to see why Queen Mary’s project is being held up as a model for others. In the UK, however, the project is somewhat of an oddity, but through the lens of QMUL you can see a glimpse of the future, where compute is not only solving the mysteries of our universe but heating our morning showers. The question remains, though, why data center waste heat utilization projects in the UK are few and far between, and how the country can catch up to regions such as the Nordics, which has embedded waste heat utilization into the planning and construction of its data center sector.


Redefining cyber-resilience for a new era

The biggest vulnerability is still the human factor, not the technology. Many companies invest in expensive tools but overlook the behaviour and mindset of their teams. In regions experiencing rapid digital growth, that gap becomes even more visible. Phishing, credential theft and shadow IT remain common ways attackers gain access. What’s needed is a shift in culture. Cybersecurity should be seen as a shared responsibility, embedded in daily routines, not as a one-time technical solution. True resilience begins with awareness, leadership and clarity at all levels of the organisation. ... Leaders play a crucial role in shaping that future. They need to understand that cybersecurity is not about fear, but about clarity and long-term thinking. It is part of strategic leadership. The leaders who make the biggest impact will be the ones who see cybersecurity as cultural, not just technical. They will prioritise transparency, invest in ethical and explainable technology, and build teams that carry these values forward. ... Artificial Intelligence is already transforming how we detect and respond to threats, but the more important shift is about ownership. Who controls the infrastructure, the models and the data? Centralised AI, controlled by a few major companies, creates dependence and limits transparency. It becomes harder to know what drives decisions, how data is used and where vulnerabilities might exist.


Building Your Geopolitical Firewall Before You Need One

In today’s world, where regulators are rolling out data sovereignty and localization initiatives that turn every cross-border workflow into a compliance nightmare, this is no theoretical exercise. Service disruption has shifted from possibility to inevitability, and geopolitical moves can shut down operations overnight. For storage engineers and data infrastructure leaders, the challenge goes beyond mere compliance – it’s about building genuine operational independence before circumstances force your hand. ... The reality is messier than any compliance framework suggests. Data sprawls everywhere, from edge, cloud and core to laptops and mobile devices. Building walls around everything does not offer true operational independence. Instead, it’s really about having the data infrastructure flexibility to move workloads when regulations shift, when geopolitical tensions escalate, or when a foreign government’s legislative reach suddenly extends into your data center. ... When evaluating sovereign solutions, storage engineers typically focus on SLAs and certifications. However, Oostveen argues that the critical question is simpler and more fundamental: who actually owns the solution or the service provider? “If you’re truly sovereign, my view is that you (the solution provider) are a company that is owned and operated exclusively within the borders of that particular jurisdiction,” he explains.


The 5 elements of a good cybersecurity risk assessment

Companies can use a cybersecurity risk assessment to evaluate how effective their security measures are. This provides a foundation for deciding which security measures are important — and which are not. But also for deciding when a product or system is secure enough and additional measures would be excessive. When they’ve done enough cybersecurity. However, not every risk assessment fulfills this promise. ... Too often, cybersecurity risk assessments take place solely in cyberspace — but this doesn’t allow meaningful prioritizing of requirements. “Server down” is annoying, but cyber systems never exist for their own sake. That’s why risk assessments need a connection to real processes that are mission critical for the organization — or perhaps not. ... Without system understanding, there is no basis for attack modeling. Without attack modeling, there is no basis for identifying the most important requirements. It shouldn’t really be cybersecurity’s job to create system understanding. But since there is often a lack of documentation in IT, OT, or for cyber systems in general, cybersecurity is often left to provide it. And if cybersecurity is the first team to finally create an overview of all cyber systems, then it’s a result that is useful far beyond security risk assessment. ... Attack scenarios are a necessary stepping stone to move your thinking from systems and real-world impacts to meaningful security requirements — no more and no less. 


Finding Strength in Code, Part 2: Lessons from Loss and the Power of Reflection

Every problem usually has more than one solution. The engineers who grow the fastest are the ones who can look at their own mistakes without ego, list what they’re good at and what they're not, and then actually see multiple ways forward. Same with life. A loss (a pet, a breakup, whatever) is a bug that breaks your personal system. ... Solo debugging has limits. On sprawling systems, we rally the squad—frontend, backend, QA—to converge faster. Similarly, grief isn't meant for isolation. I've leaned on my network: a quick Slack thread with empathetic colleagues or a vulnerability share in my dev community. It distributes the load and uncovers blind spots you might miss on your own. ... Once a problem is solved, it is essential to communicate the solution. The list of lessons from that solution: some companies solve problems, but never put the effort into documenting the process in a way that prevents them from happening again. I know it is impossible to avoid problems, as it is impossible not to make mistakes in our lives. The true inefficiency? Skipping the "why" and "how next time." ... Borrowed from incident response, it's a structured debrief that prevents recurrence without finger-pointing. In engineering, it ensures resilience; in life, it builds emotional antifragility. There are endless flavours of postmortems—simple Markdown outlines to full-blown docs—but the gold standard is "blameless," focusing on systems over scapegoats.


Cyber resilience is a business imperative: skills and strategy must evolve

Cyber upskilling must be built into daily work for both technical and non-technical employees. It’s not a one-off training exercise; it’s part of how people perform their roles confidently and securely. For technical teams, staying current on certifications and practicing hands-on defense is essential. Labs and sandboxes that simulate real-world attacks give them the experience needed to respond effectively when incidents happen. For everyone else, the focus should be on clarity and relevance. Employees need to understand exactly what’s expected of them; how their individual decisions contribute to the organization's resilience. Role-specific training makes this real: finance teams need to recognize invoice fraud attempts; HR should know how to handle sensitive data securely; customer service needs to spot social engineering in live interactions. ... Resilience should now sit alongside financial performance and sustainability as a core board KPI. That means directors receiving regular updates not only on threat trends and audit findings, but also on recovery readiness, incident transparency, and the cultural maturity of the organization's response. Re-engaging boards on this agenda isn’t about assigning blame—it’s about enabling smarter oversight. When leaders understand how resilience protects trust, continuity, and brand, cybersecurity stops being a technical issue and becomes what it truly is: a measure of business strength.
