  • Craigslist at 30: No Algorithms, No Ads, No Problem
    by msmash on 09/01/2026 at 5:24 pm

    Craigslist, the 30-year-old classifieds site that looks virtually unchanged since the dial-up era, continues to draw more than 105 million monthly users and remains enormously profitable despite never spending a cent on advertising or marketing. The site ranks as the 40th most popular website in the United States, according to Internet data company Similarweb. University of Pennsylvania associate professor Jessa Lingel called it the "ungentrified" Internet. Unlike Facebook Marketplace, Etsy, or DePop, Craigslist doesn't use algorithms to track users or predict what they want to see. There are no public profiles, no rating systems, no likes or shares. The site effectively disincentivizes the clout-chasing and virality-seeking that dominates platforms like TikTok and Instagram. Craigslist began in 1995 as an email list for a few hundred San Francisco Bay Area locals sharing events and job openings. Engineer Craig Newmark even recruited CEO Jim Buckmaster through a site ad. The two spent roughly a decade battling eBay in court after the tech giant purchased a minority stake in 2004, ultimately buying back shares and regaining full control in 2015.

  • iOS 26 Shows Unusually Slow Adoption Months After Release
    by msmash on 09/01/2026 at 4:45 pm

    Apple's iOS 26 appears to be witnessing the slowest adoption rate in recent memory, with third-party analytics from StatCounter indicating that only 15 to 16% of active iPhones worldwide are running the operating system nearly four months after its September release. The figures stand in stark contrast to iOS 18, which had reached approximately 63% adoption by January 2025, and iOS 17, which hit 54% by January 2024. iOS 16 had surpassed 60% by January 2023. StatCounter's breakdown for January 2026 shows iOS 26.1 accounting for roughly 10.6% of devices, iOS 26.2 at about 4.6%, and the original iOS 26.0 at 1.1%. More than 60% of iPhones tracked by the analytics firm remain on iOS 18. MacRumors' own visitor data tells a similar story: 89.3% of the site's readers were on iOS 18 during the first week of January 2025, but only 25.7% are running iOS 26 during the same period this year. iOS 26 introduced Liquid Glass, a sweeping visual redesign that replaces much of the traditional opaque interface with translucent layers, blurred backgrounds, and dynamic depth effects.

  • Amazon Wants To Know What Every Corporate Employee Accomplished Last Year
    by msmash on 09/01/2026 at 4:05 pm

    Amazon is now requiring its corporate employees to submit a list of three to five accomplishments that represent their best work as part of an overhauled performance review process, according to Business Insider, which cites internal documents. The company's internal Forte review system previously asked employees softer questions like "When you're at your best, how do you contribute?" but the new standards place greater emphasis on individual productivity and specific deliverables. Amazon's roughly 350,000 corporate employees must also outline actions they plan to take to continue growing at the company. Read more of this story at Slashdot.

  • Send To Kindle from Microsoft Word is Discontinued
    by msmash on 09/01/2026 at 3:30 pm

    Microsoft is discontinuing its Send to Kindle integration in Word, ending a feature that allowed Microsoft 365 subscribers to send documents directly to their Kindle e-readers and preserve complex formatting through fixed layouts. The company updated its documentation to announce that beginning February 9th, 2026, the Send to Kindle feature will no longer work across Web, Win32, and Mac platforms. Microsoft has not disclosed why it's killing the integration but recommends users switch to Amazon's official Send to Kindle app. The feature launched in 2023 and was particularly valued by Kindle Scribe owners who could annotate the transferred documents.

  • Why Care About Debt-to-GDP?
    by msmash on 09/01/2026 at 2:59 pm

    Abstract of a paper on NBER: We construct an international panel data set comprising three distinct yet plausible measures of government indebtedness: the debt-to-GDP, the interest-to-GDP, and the debt-to-equity ratios. Our analysis reveals that these measures yield differing conclusions about recent trends in government indebtedness. While the debt-to-GDP ratio has reached historically high levels, the other two indicators show either no clear trend or a declining pattern over recent decades. We argue for the development of stronger theoretical foundations for the measures employed in the literature, suggesting that, without such grounding, assertions about debt (un)sustainability may be premature.

  • Record Ocean Heat is Intensifying Climate Disasters, Data Shows
    by msmash on 09/01/2026 at 2:07 pm

    The world's oceans absorbed yet another record-breaking amount of heat in 2025, continuing an almost unbroken streak of annual records since the start of the millennium and fueling increasingly extreme weather events around the globe. More than 90% of the heat trapped by humanity's carbon emissions ends up in the oceans, making ocean heat content one of the clearest indicators of the climate crisis's trajectory. The analysis, published in the journal Advances in Atmospheric Sciences, drew on temperature data collected across the oceans and collated by three independent research teams. The measurements cover the top 2,000 meters of ocean depth, where most heat absorption occurs. The amount of heat absorbed is equivalent to more than 200 times the total electricity used by humans worldwide. This extra thermal energy intensifies hurricanes and typhoons, produces heavier rainfall and greater flooding, and results in longer marine heatwaves that decimate ocean life. The oceans are likely at their hottest in at least 1,000 years and heating faster than at any point in the past 2,000 years. Read more of this story at Slashdot.
