Retrospective traces Lotus Notes' roots to 1970s PLATO campus messaging system

A historical piece revisits how Lotus Notes, launched in 1989, offered encryption, rich formatting, read receipts, and app-building tools years before equivalent standards like MIME or PGP existed for email. It traces the software's conceptual origins back to a 1973 University of Illinois project called PLATO Notes, built by a teenage programmer, David Woolley, to replace a chaotic open text file used for campus communication.

Sporty & Rich Founder Emily Oberg Drops AI Photo Shoots After Disappointing Results

Emily Oberg, founder of fashion brand Sporty & Rich, revealed she tested AI-generated imagery to cut costs on e-commerce photo shoots, which typically run upwards of $200,000 twice a year. She said the results looked flat, lifeless and overly perfect, with models appearing 'dead in the eyes,' prompting her to return to using a full human team for future shoots.

Dual-band routers explained: how 2.4GHz and 5.0GHz Wi-Fi work together

Dual-band routers transmit Wi-Fi simultaneously on two frequencies, 2.4GHz and 5.0GHz, to spread device traffic across separate channels instead of one shared lane. The 2.4GHz band covers longer distances and passes through walls better but runs slower and gets crowded, while the 5.0GHz band delivers faster speeds and more capacity at the cost of range. Most modern routers automatically assign devices to whichever band suits them, though some networks still show separate SSIDs for each frequency.

Guide: How Much Home Internet Speed You Actually Need in 2024

Streaming and video-call services have modest bandwidth needs on their own—Netflix 4K needs just 15 Mbps and Zoom calls need under 5 Mbps—but households with multiple devices running simultaneously need far more headroom. Experts recommend at least 100 Mbps for one or two people, 300 Mbps for larger or work-from-home households, and 500 Mbps or more for heavy users, while noting the FCC's official broadband baseline is now 100 Mbps down and 20 Mbps up.

Attackers empty 95% of Liquid Network's federation wallet, claim white-hat intent

Blockstream's Liquid Bitcoin sidechain confirmed that hackers withdrew about 4,000 BTC—roughly 95% of its federation wallet, worth roughly $320 million—on September 6. The attackers embedded an on-chain message calling themselves 'whitehats,' asking Liquid to patch the vulnerability before they return the funds, and Liquid has since suspended transactions while shifting communication to an encrypted channel.

Poorly chosen registered agents risk fines and business dissolution, compliance experts warn

Business owners who assign registered-agent duties to a friend, relative or themselves risk missing critical legal and government deadlines. States like Florida and California impose penalties of $250 to $400 for late reports or outdated company information, and repeated violations can result in a business being forcibly dissolved. A compliance firm founder explains the recurring damage caused by informal or unqualified registered agent choices.
