Cybersecurity’s center of gravity is shifting. Cloud infrastructure, software supply chains, AI agents, data security, and autonomous defense are creating new categories and giving a new generation of security CEOs plenty to talk about. These 11 executives stand out not necessarily because they run the largest cybersecurity companies, but because their companies and ideas are increasingly part of the industry conversation. 1. Amiram Shachar, Upwind Amiram Shachar is having a particularly con...

Several new studies have uncovered this long overlooked aspect of coral physiology that could be the key to the animals’ fate in a changing climate.

Understanding how ChatGPT’s latest memory upgrade works will help you get even more out of OpenAI’s productivity tool.

Amazon is a murky mess of ads, unknown sellers, misleading sales, and specious information. Stay safe while shopping on Prime Big Deal Days and beyond with these tips and tricks.

The FCC banned the sale of new consumer-grade Wi-Fi routers and mobile hot spots manufactured outside the US. Here’s what it means for you.

“You know ‘Bang Bus’? We don’t want that.”

The president has doubled down on data centers and AI. His base is running in the opposite direction.

The Muse app continues Meta’s trend of opting users into data collection for AI training. It also nudges you to share your bank account, email, and passport information.

“This is a place where you can come and say, I fucking hate my dog today,” a Dogs Anonymous cofounder tells WIRED. “And there are people who are going to be like, yeah, that was me last Tuesday.”

Thermacell LIV 2.0 is expensive and imperfect, but it outperforms nearly every mosquito-control method I’ve tried.

Most backend interview prep advice is either "grind 500 LeetCode problems" or "just build projects." Neither alone gets you hired. After mentoring freshers into backend roles, here's the actual breakdown of what interviewers test — and how to prepare for each part efficiently. 1. Language + runtime fundamentals (the fastest points to lose) For Node.js roles, interviewers almost always probe: The event loop — phases, the microtask queue, and why process.nextTick runs b...

Started building a reranker CLI on top of Jev for the obvious reason: get the relevant documents to the top. Ended up with three modes in jev-reranker , and one I decided not to ship. The split appeared while I was building. There are several different things I want decided about a set of search results. Is this document related to the question? Does it contain evidence I can answer from? Which part of it should I pass on? Given what I have already selected, does this add anything? All fo...

Over the past two months, a cluster of papers has appeared on arXiv from teams at Alibaba's DreamX group, Meta AI, Google Cloud, ByteDance Seed, and others — all aimed at the same target: the agent harness , the runtime layer wrapped around the model that handles context construction, state management, tool invocation, error recovery, and result verification. The term is so new it didn't have an agreed definition until recently. A researcher at Brazil's Federal Institute of Goiás published a...

This is a submission for the Sanity Challenge , Path One: Ship an Agent That Queries Real Content What I Built CabinClaim is a cabin-rules desk, not a travel blog. A guest asks one question. The desk answers what is allowed in the cabin for this carrier and this travel date from dated ruleClaim documents in Sanity. It does not search the web at ask time. This only works because the content is structured. Official pages stay live at the same time and disagree: TSA p...

Fixed Window rate limiting algorithm Fixed Window rate limiting algorithm enforces a limit on the number of events allowed within a time window. "Maximum 5 password attempts in 10 minutes" is a classic example. The common misconception about Fixed Window is that people describe it as "allows N requests per fixed calendar window" and then warn about the "burst at boundary" problem. Flexible Fixed Window Algorithm I call it flexible, because somehow the developer community h...

DNS Traffic Management: How DNS Keeps Websites Reachable When Failures Occur Executive Thesis Domain Name System (DNS) traffic management acts as the global control plane for application availability, shifting traffic away from degraded endpoints long before clients experience session termination. Modern distributed systems rely on DNS not merely for name resolution, but as an active tier for latency optimization, weighted capacity shifting, and automated disaster recovery. Howe...

Serverless Execution Architecture: How Platforms Start Functions Without Persistent Processes Serverless platforms decouple application code from persistent infrastructure by dynamically orchestrating execution environments on demand. Rather than keeping every registered function running continuously, modern function-as-a-service (FaaS) systems leverage intelligent schedulers, isolated execution runtimes, and lifecycle management controllers to provision compute resources only when invocatio...

Admission control is a fence, not a conversation. A free language-model call is a variable-latency guess with an untrusted prompt surface, and it does not belong on the path that decides whether a request may enter a production service. The temptation is obvious in an industry that now asks models to classify almost everything. Abuse often looks like language. Support tickets look like language. Even a User-Agent string can be dressed up as a story about intent. Teams then sketch a “smart she...

Database Index Overhead: Write Amplification, Cache Pressure, and Maintenance Costs Database indexes are routinely treated as default performance remedies for sluggish queries. When a query scan latency spikes, developers add an index without evaluating the systemic tax imposed on the write path. Every secondary index transforms a localized write operation into a multi-page routing problem across storage engines, transaction logs, and memory buffers. Unchecked indexing induces severe write a...
