Public relations has always been about three things: influence, reputation and authority. But in 2025, influence looks different. It’s no longer just about securing the Wall Street Journal or a glossy feature—it’s about whether your brand shows up in AI answers. Generative search has rewritten the rules of visibility. Today, the most powerful drivers of … Read more

In 2016, the ISS was still running on Intel 80386SX 20 MHz processors, which were already a quarter of a century old. GLONASS ground stations are equipped with the first version of Elbrus. In “small space”, the priorities are different: low cost, rapid iteration, and the use of CubeSats on Raspberry Pi and Linux containers. … Read more

Zhining Zhao, founder of Andean, believes America’s tech future lies in its waste. His startup builds AI-powered refineries that reclaim metals from e-waste, cutting costs and emissions while feeding U.S. supply chains. From a censored school paper in Shanghai to leading deeptech in the U.S., Zhao proves discarded systems can spark renewal.

Introduction For two decades, our interaction with the digital world has been confined to a mere 5-inch screen and a single fingertip. But what if we could break free from these limitations and unlock the full spectrum of our innate human senses in our everyday computing? The past few years have witnessed a dramatic acceleration … Read more

The rapid ascension of Large Language Models (LLMs) and conversational AI has undeniably reshaped our technological landscape. Yet, for all the buzz and speculation, a critical question has remained largely unanswered: how are people actually using these powerful tools in their daily lives and work? Until now, much of our understanding has relied on self-reported … Read more

Thoroughly protecting GitHub should arguably be on most cybersecurity organizations’ priority list.

This article explores how overreliance on AI weakens our critical thinking, with insights from a new MIT study on cognitive decline in LLM users.

Clarke’s ring of satellites became the backbone of global communications and most astronomers and engineers say science fiction was an influence on their careers. Stories and technical papers feed into each other, creating a feedback loop. The Clarke Belt, once a thought experiment, is now a busy highway of spacecraft. As we manage orbital debris, … Read more

AI is hungry. Not just for data, but for real-time data – processed fast, everywhere, all the time. From self-driving cars to drone swarms to predictive healthcare; artificial intelligence has evolved over the years, and which each passing evolution, there is an increasing dependance on regularly updated (and re-opted) real-time data… AI is currently changing … Read more

The world is entering its ‘crypto era’. The headlines say it, the wallets prove it and the inflow in capital is speeding up (hello spot Bitcoin ETFs). Yet adoption hasn’t even hit full stride yet. Look at Australia for example: crypto adoption hovers around the 20% mark and dived 3% due to concerns around crypto … Read more

In this series of articles about agents in cybersecurity, specifically pentesting, I will examine and describe various online projects, explain their operating principles, test their functionality, verify the quality of the results, and summarize. In parallel, we will develop our own pentesting agent from start to finish, testing various language models, both for local use … Read more

The deepfake identity crisis is not an abstract problem for the future; it is a pressing issue that demands attention now.

For all the talk about the “future of work,” most companies still manage people the way they did a century ago: with opinions, checklists, and annual reviews. HR may run on laptops and cloud dashboards, but beneath the surface it’s still an analog machine. Performance is assessed through 180° or 360° feedback, manager impressions, and … Read more

Why PHI Data Feels Like a Ticking Time Bomb Healthcare data is both priceless and dangerous. Priceless, because it fuels analytics, machine learning, and better patient outcomes. Dangerous, because a single leak of Protected Health Information (PHI) can destroy trust and trigger massive compliance penalties. Moving PHI through ETL pipelines is like carrying a glass … Read more

Everyone’s talking about AI trading bots, how they can enhance fraud detection, optimize liquidity provision, and even analyze market trends in once unfeasible ways. And they’re right, bots can do all these things better than their human operators. But despite these clear benefits, crypto exchanges should think carefully before proffering proprietary trading bots to retail … Read more

Rulebook-AI offers a way to define rules once, and generate the rest automatically.

Silicon Valley has a notoriously short memory. In 2023, we were recovering from the 2020-2022 zero-interest-rate policy (ZIRP), a period during which startup fundraising and valuations were irrational. (Remember when Fast raised at 1B+ valuation, hired 500 people but only generated $600K in revenue?) Then, the correction hit hard. A record number of startups shut … Read more
