Welcome to HackerNoon’s Meet the Writer Interview series, where we learn a bit more about the contributors that have written some of our favorite stories. So let’s start! Tell us a bit about yourself. For example, name, profession, and personal interests. I’ve spent years as a professor of engineering physics, but at heart, I’m a storyteller with a deep love for sci-fi. When I’m not in the lab, you can find me sailing, travelling, or chasing an adrenaline […]

We study the theoretical behavior of denoising score matching–the learning task associated to diffusion models–when the data distribution is supported on a low-dimensional manifold and the score is parameterized using a random feature neural network. We derive asymptotically exact expressions for the test, train, and score errors in the high-dimensional limit. Our analysis reveals that, for linear manifolds the sample complexity required to learn the score function scales linearly with the intrinsic dimension of the manifold, rather than […]

Safe reinforcement learning (RL) is a standard paradigm for safety-critical decision making. However, real-world safety constraints can be complex, subjective, and even hard to explicitly specify. Existing works on constraint inference rely on restrictive assumptions or extensive expert demonstrations, which is not realistic in many real-world applications. How to cheaply and reliably learn these constraints is the major challenge we focus on in this study. While inferring constraints from human preferences offers a data-efficient alternative, we identify the […]

Salesforce employs thousands of engineers and has practically ingested data from every major enterprise on the planet. They have a market cap of around $200B. But still, it is a manual process for a sales representative to figure out which accounts to prioritize and which features to pitch to which customers in order to gain revenue for their company. This is not a data problem, but an inference problem. The data already exists in the salesforce instance of […]

SQL is still central to modern systems, but much of the work around it is repetitive. Developers spend hours fixing typos, reformatting queries, and rewriting patterns they already know by heart. To be precise, nearly 40% of SQL time goes into these routine tasks every week. That’s a big reason AI tools are spreading so quickly. Today, about 84% of developers already use, or plan to use, AI to handle this kind of work. Instead of wrestling with boilerplate, this helps engineers focus on design, […]

For a long time, stablecoins were treated like backstage tools in crypto. Traders used them to move between volatile assets. DeFi users used them for lending, swaps, and yield. Outside that world, most people barely cared. That is changing. Stablecoins are starting to look less like crypto products and more like internet-native money. The real shift is not hype. It is a utility. Businesses want faster settlement. Freelancers want easier cross-border payments. Platforms want global checkout options. Users […]

Define “correct” before you index anything RAG systems are judged by answers, but you cannot improve what you cannot measure. Before you touch embeddings, pick the real tasks your assistant must handle, then define success criteria in plain language. Keep the task list small. Common high-value tasks are Q&A over policy or product docs, troubleshooting workflows, summarisation with citations, and “what changed” across document versions. For each task type, define what a correct answer must do. Examples: it […]

For years, hacking was treated like a hard skill game. The best attackers were the ones who could code from scratch, chain exploits, reverse engineer software, and move through systems without leaving obvious traces. Skill created separation. Experience created power. That is starting to change. The next big cybersecurity shift may not come from hackers becoming dramatically smarter. It may come from them becoming dramatically more efficient. Because now, instead of needing better technical skills, many attackers may […]
