Walmart is Ditching ZIP Codes in Favor of Honeycomb-Style Maps As It Looks To Speed Up Deliveries

Slashdot.org - Tue, 04/22/2025 - 15:00
Walmart is taking a lesson from the humble honeybee in its quest to make its deliveries as fast as possible. From a report: The retail giant already boasts a formidable store count of 4,700 locations across the US, which puts it within a short drive of more than 90% of households. But in order to grow its reach without necessarily having to build new supercenters, Walmart says it has been using a relatively new hexagonal map segmentation -- a change from the conventional ZIP code or radius-based strategies that are commonly used in determining delivery areas. Walmart says the strategy allows it to better understand where customers are and which stores have what they want. As bees have long known, hexagons can be an excellent shape for making the most of a given space, and Walmart says the more precise maps allow it to reach an additional 12 million US households with same-day delivery. "This is helping us to adapt how we service our customers, by allowing us to go from a fixed-mile radius into a much more dynamic catchment area that caters to the needs of the customers that a particular store will serve," Walmart global tech senior director of engineering Parthibban Raja told Fast Company in December, following a pilot of the concept. Walmart says its platform uses a combination of its own data and open-source software to create new delivery zones.

At Trial, Instagram Co-founder Says Zuckerberg Withheld Resources Over 'Threat' Fears

Slashdot.org - Tue, 04/22/2025 - 14:20
An anonymous reader shares a report: Kevin Systrom, the co-founder of Instagram, testified on Tuesday in a landmark federal antitrust trial that he left Meta in 2018 because his company was denied resources. The government has argued that Meta purchased Instagram in 2012 as part of a "buy-or-bury strategy" to illegally cement its social media monopoly by killing off its rivals. Last week, current and former Meta executives testified that the social media giant, formerly known as Facebook, used its deep pockets to invest in Instagram after its purchase. In testimony at the U.S. District Court of the District of Columbia, Mr. Systrom painted a different picture, saying he left Meta because Mark Zuckerberg, the chief executive, wasn't investing enough. At that time, Instagram had grown to 1 billion users, about 40 percent of Facebook's size, yet the photo-sharing app had only 1,000 employees compared to 35,000 employees at Facebook, he said. "We were by far the fastest growing team. We produced the most revenue and relative to what we should have been at the time, I felt like we should have been much larger," said Mr. Systrom, who is expected to testify for six hours. Mr. Systrom said he found the decisions baffling. When asked by an F.T.C. lawyer why Mr. Zuckerberg might have decided to give Instagram fewer resources, Mr. Systrom said it was a consistent pattern during his tenure at Meta. "Mark was not investing in Instagram because he believed we were a threat to their growth," he said, referring to Mr. Zuckerberg's prioritization of Facebook.

Companies Ditch Fluorescent Lights in Battle for Office Return

Slashdot.org - Tue, 04/22/2025 - 13:40
Offices nationwide are ditching harsh fluorescent lighting in favor of advanced systems designed to improve cognitive function and entice remote workers back to physical workplaces. Companies are investing in circadian-tuned lighting that adjusts intensity and color temperature throughout the day to mimic natural light patterns, syncing with employees' biological rhythms, according to WSJ. The technology arsenal includes faux skylights displaying virtual suns and moons, AI-controlled self-tinting windows, and customizable lighting zones that can be adjusted via remote control. Research suggests these innovations may improve brain function during tasks requiring sustained attention. "We've known for a long time that natural light is better and makes people feel better," says Peter Cappelli, professor at Wharton School. The innovations stem from discoveries in the early 2000s of photosensitive retinal cells that affect biology independent of vision. Industry specialists report a "huge uptick in requests," though implementation adds 20-30% to project costs, potentially slowing mainstream adoption.

AI Floods Amazon With Strange Political Books Before Canadian Election

Slashdot.org - Tue, 04/22/2025 - 13:00
An anonymous reader shares a report: Canada has seen a boom in political books created with generative artificial intelligence, adding to concerns about how new technologies are affecting the information voters receive during the election campaign. Prime Minister Mark Carney was the subject of at least 16 books published in March and listed on Amazon.com, according to a review of the site on April 16. Five of those were published on a single day. In total, some 30 titles were published about Carney this year and made available on Amazon -- but most were taken down from the site after inquiries from Bloomberg News. One author, James A. Powell, put his name to at least three books about the former central banker, who's now leading the Liberal Party and is narrowly favored to win the election. Among the titles that Amazon removed: "Carney's Code: Climate Capitalism, Digital Currencies, and the Technocratic Takeover of the Global Economy -- Inside Mark Carney's Blueprint for the Post-Democratic World."

Google Chrome To Continue To Use Third-Party Cookies in Major Reversal

Slashdot.org - Tue, 04/22/2025 - 12:20
An anonymous reader shares a report: In a shocking development, Google won't roll out a new standalone prompt for third-party cookies in Chrome. It's a move that amounts to a U-turn on the Chrome team's earlier updated approach to deprecating third-party cookies, announced in July last year, with the latest development bound to cause ructions across the ad tech ecosystem. "We've made the decision to maintain our current approach to offering users third-party cookie choice in Chrome, and will not be rolling out a new standalone prompt for third-party cookies," wrote Anthony Chavez, vp Privacy Sandbox at Google, in a blog post published earlier today (April 22). "Users can continue to choose the best option for themselves in Chrome's Privacy and Security Settings." However, it's not the end of Privacy Sandbox, according to Google, as certain initiatives incubated within the project are set to continue, such as its IP Protection for Chrome Incognito users, which will be rolled out in Q3.

The Effect of Deactivating Facebook and Instagram on Users' Emotional State

Slashdot.org - Tue, 04/22/2025 - 11:40
Abstract of a paper on National Bureau of Economic Research: We estimate the effect of social media deactivation on users' emotional state in two large randomized experiments before the 2020 U.S. election. People who deactivated Facebook for the six weeks before the election reported a 0.060 standard deviation improvement in an index of happiness, depression, and anxiety, relative to controls who deactivated for just the first of those six weeks. People who deactivated Instagram for those six weeks reported a 0.041 standard deviation improvement relative to controls. Exploratory analysis suggests the Facebook effect is driven by people over 35, while the Instagram effect is driven by women under 25.

Apple Removes 'Available Now' Claim from Intelligence Page Following NAD Review

Slashdot.org - Tue, 04/22/2025 - 11:00
Apple has quietly removed the "available now" designation from its Apple Intelligence marketing page following a National Advertising Division review. The change came after the NAD recommended Apple "discontinue or modify" the claim, which "reasonably conveyed the message" that all promoted AI features were immediately available with iPhone 16 devices. The NAD, part of the Better Business Bureau, determined Apple's footnote explaining feature availability was "neither sufficiently clear and conspicuous nor close to the triggering claims." Further reading: Apple Delays 'More Personalized Siri' Apple Intelligence Features; 'Something Is Rotten in the State of Cupertino'; Apple Shakes Up AI Executive Ranks in Bid to Turn Around Siri.
