These are our favorite cyber books on hacking, espionage, crypto, surveillance, and more

In the last 30 years or so, cybersecurity has gone from being a niche specialty within the larger field of computer science, to an industry estimated to be worth more than $170 billion made of a globe-spanning community of hackers. In turn, the industry’s growth, and high-profile hacks such as the 2015 Sony breach, the 2016 U.S. election hack and leak operations, the Colonial Pipeline ransomware attack, and a seemingly endless list of Chinese government hacks, have made cybersecurity and hacking

FFmpeg devs boast of another 100x leap thanks to handwritten assembly code

The developers behind the FFmpeg project are again claiming major performance uplifts delivered by wielding the art of handwritten assembly code. With the latest patch applied, users should see a “100x speedup” in the cross-platform open-source media transcoding application. However, the developers were soon to clarify that the 100x claim applies to just a single function, “not the whole of FFmpeg.” BREAKING: FFmpeg 100x speedup from handwritten assembly13:55:30 <•haasn> rangedetect8_avx512: 12

Staying cool without refrigerants: Next-generation Peltier cooling

On June 28, Samsung Electronics, together with the Johns Hopkins University Applied Physics Laboratory (APL), published a paper on next-generation Peltier cooling technology in the prestigious scientific journal Nature Communications. The team successfully developed a high-efficiency thin-film semiconductor Peltier device using nano-engineering technology and demonstrated refrigerant-free cooling, highlighting the potential to deliver outstanding performance without conventional refrigerants.

AI Will Replace Recruiters and Assistants in Six Months, Says CEO Behind ChatGPT Rival

Aravind Srinivas, the CEO of the ambitious AI startup Perplexity, has a clear and startling vision for the future of work. It begins with a simple prompt and ends with the automation of entire professional roles. “A recruiter’s work worth one week is just one prompt: sourcing and reach outs,” Srinivas stated in a recent interview with The Verge’s Decoder” podcast, a prediction that serves as both a mission statement for his new AI-powered browser, Comet, and a stark warning for the modern knowl

Chinese Scientists Invent System for Extracting Oxygen, Water and Rocket Fuel From Moon Dust

Chinese researchers say they've devised a new way to extract water from lunar soil and convert it into fuel. As detailed in a new paper published today in the journal Joule, the team found that their proposed "photothermal strategy" — essentially converting light into heat — could effectively convert carbon dioxide from extracted water into carbon monoxide, hydrogen, and oxygen gas, a "potential route for sustaining human life on the Moon and enabling long-term extraterrestrial exploration."

Scientists Find Evidence of Grim Long-Term Effects of Fad Diets

Image by Getty Images Studies The way Westerners diet — often alternating dubious and restrictive food regimens with binge eating, in a phenomenon known as "yo-yo dieting" — may be messing with their gut flora and their brains. In a new study published in the journal Advanced Science, researchers from France's University of Rennes and Paris-Saclay University found, after conducting a series of studies with mice, that yo-yo diets appeared to result in long-lasting changes to their gut bacteria.

These are the 6 Android widgets I simply can’t live without

Megan Ellis / Android Authority From calendars to reminder apps, everyone has their own list of the best Android widgets. For me, widgets help me get overviews of various things without needing to open up the app that they’re linked to. I recently switched to a new smartphone, and while there are certain things I do whenever I set up a new phone, I also realized that I needed to refresh some of my widget setups. As a result, these ones have become indispensable to my daily routine. 1. TickTic

HPE warns of hardcoded passwords in Aruba access points

Hewlett-Packard Enterprise (HPE) is warning of hardcoded credentials in Aruba Instant On Access Points that allow attackers to bypass normal device authentication and access the web interface. Aruba Instant On Access Points are compact, plug-and-play wireless (Wi-Fi) devices, designed primarily for small to medium-sized businesses, offering enterprise-grade features (guest networks, traffic segmentation) with cloud/mobile app management. The security issue, tracked as CVE-2025-37103 and rated

Microsoft SharePoint zero-day exploited in RCE attacks, no patch available

A critical zero-day vulnerability in Microsoft SharePoint, tracked as CVE-2025-53770, has been actively exploited since at least July 18th, with no patch available and at least 85 servers already compromised worldwide. In May, Viettel Cyber Security researchers chained two Microsoft SharePoint flaws, CVE-2025-49706 and CVE-2025-49704, in a "ToolShell" attack demonstrated at Pwn2Own Berlin to achieve remote code execution. While Microsoft patched both ToolShell flaws as part of the July Patch T

How the 'Minecraft' Score Became Big Business for Its Composer

In 2009, in between full-time shifts at a local factory, then-19-year-old musician Daniel Rosenfeld composed a score for an independent video game. “It was just a side hustle, maybe not even that. It was a hobby, really,” explains Rosenfeld, who records under the name C418. The game, Minecraft, turned out to be successful beyond Rosenfeld’s wildest dreams. In 2014, Microsoft purchased Minecraft’s Swedish developer, Mojang Studios, for $2.5 billion, and through 2023, it had sold 300 million copi

LLM architecture comparison

It has been seven years since the original GPT architecture was developed. At first glance, looking back at GPT-2 (2019) and forward to DeepSeek-V3 and Llama 4 (2024-2025), one might be surprised at how structurally similar these models still are. Sure, positional embeddings have evolved from absolute to rotational (RoPE), Multi-Head Attention has largely given way to Grouped-Query Attention, and the more efficient SwiGLU has replaced activation functions like GELU. But beneath these minor refi

Do Contact Lenses Expire? Everything Eye Doctors Want You to Know About Replacing Your Contacts

If you wear contact lenses, you probably don't think much about them. But they're a relatively new invention -- in fact, the first disposable contact lens wasn't introduced until 1982. "We think of contact lenses as being so normal, but 100 years ago, nobody walked around with little pieces of plastic over their eyes," says ophthalmologist Dr. Robert Kinast, the vice chair of ophthalmology at Legacy Devers Eye Institute and co-founder of GentleDrop. "Contact lenses are foreign bodies and should

Psychiatric Researchers Warn of Grim Psychological Risks for AI Users

Without even looking at medical data, it's pretty clear that "artificial intelligence" — a vast umbrella term for various technologies over the years, but currently dominated by the data-hungry neural networks powering chatbots and image generators — can have life-altering effects on the human brain. We're not even three years out from the release of the first commercially-available LLM, and AI users have already been driven to paranoid breaks from reality, religious mania, and even suicide. A
