Beyond the Logo: How We're Weaving Full Images Inside QR Codes

QR codes are everywhere. They’re incredibly functional, connecting our physical and digital worlds with a simple scan. But let's be honest: most of them are an eyesore. The standard black-and-white pixelated square often feels like a necessary evil that disrupts an otherwise beautiful design. The common solution has been to leverage the QR code's built-in error correction to place a logo in the center. While functional, it’s still an overlay—a sticker on top of the data. We thought, what if the

Can AI Predict Powerball Numbers?

With the Powerball ballooning to $650 million after Wednesday’s drawing, hopeful players have been asking: Is winning the lottery a matter of luck or something that science and artificial intelligence can predict? Three students at the University of Salento in southern Italy say that science wins out. They say they used AI to analyze patterns from past draws to predict future winning numbers. Their experimental approach resulted in a €43,000 jackpot in April, which now has people wondering if

Intel Foundry Demonstrates First Arm-Based Chip on 18A Node

Images in this post: Intel, via TechPowerUp! Intel Foundry needs external customers, as the company claims that if it doesn't find more, it may have to "pause or discontinue our pursuit of Intel 14A and successor nodes." That could explain why the company posted a video today on its YouTube channel showing off "Deer Creek Falls", a new "reference SoC" fabricated on its 18A process.The video has since been removed, which is why we're crediting TechPowerUp on the screenshots, but it clearly sho

Shein reportedly weighs moving back to China in a bid for Hong Kong IPO approval

Shein is considering moving its base back to China from Singapore in a bid to convince Beijing authorities to approve the e-commerce company's Hong Kong initial public offering, according to a Bloomberg report on Tuesday. The report said that Shein had gone so far as to consult lawyers about setting up a parent company in mainland China, citing people familiar with the matter. However, it added that there was no guarantee that Shein would act upon the preliminary discussions. Shein, which sour

An Argument for Increasing TCP's Initial Congestion Window Again

An Argument for Increasing TCP's Initial Congestion Window ... Again Published September 2, 2024 Introduction Google has a long history of performing networking research, making changes, and pushing those changes to the entire internet. In 2011, they published one of my favorite papers, which described their decision to increase the TCP initial congestion window from 1 to 10 on their entire infrastructure. This was soon followed by an RFC filed with the IETF, and eventually became an internet

Laura Loomer and the limits of posting everything

For all the power she wields with the White House’s affairs, Laura Loomer does not have the traditional tools that her rivals in the MAGA influencer industrial complex have — the highest follower count, the most political power, the most internet platforms, etc. But the fact remains that she’s the influencer responsible for getting Donald Trump to fire over a dozen members of his administration (and counting) for the hazily-defined crime of being disloyal to MAGA. This is something that none of

A mind–reading brain implant that comes with password protection

A brain scan (artificially coloured) produced by magnetic resonance imaging. Credit: K H Fung/Science Photo Library A brain implant can decode a person’s internal chatter — but the device works only if the user thinks of a preset password1. The mind-reading device, or brain–computer interface (BCI), accurately deciphered up to 74% of imagined sentences. The system began decoding users’ internal speech — the silent dialogue in people’s minds — only when they thought of a specific keyword. This

The “Godfather of AI” Has a Bizarre Plan to Save Humanity From Evil AI

Geoffrey Hinton, the pioneering mind behind AI industry-transforming neural networks, who's often referred to as a "godfather of AI," says we need to infuse AI with "maternal instincts" to save humanity from rogue AI. Though his work on neural networks helped to usher in the large language models (LLMs) that dominate Silicon Valley today, these days, Hinton is known for being somewhat of an AI alarmist: he believes that there's a significant chance that superintelligent AI will wipe out humanki

A new poverty line shifted the World Bank's poverty data. What changed and why?

$3 a day: A new poverty line has shifted the World Bank’s data on extreme poverty. What changed, and why? In June 2025, the World Bank increased its extreme poverty estimates by 125 million people.

To track progress towards ending extreme poverty by 2030, the United Nations relies on the World Bank to estimate the share of people living below a certain threshold, calle

A Unified Approach to Branch Security and SD-WAN: Streamlining Operations

This evolution brings tremendous benefits but also presents significant challenges for IT and security teams tasked with ensuring seamless access to applications and protecting sensitive data outside the traditional corporate perimeter.
