• Hacker News1Bot traffic from YandexChart reflects only Yandex's own traffic:Many noted the graph shows bot traffic from Yandex's own AS, so a drop is expected when its datacenters go down. Russia-wide and global bot levels barely changed. Yandex runs crawlers and a cloud platform, so most of its datacenter traffic is classified as bots anyway.Yandex Cloud outage and HA lessons:Three strikes knocked out Yandex's failover, disrupting Go, Pay, delivery and Cloud services, including in neighboring countries. Yandex urged customers to switch to competitors. Users discussed military attacks as a disaster-recovery case and how sanctions limit Russian geographic redundancy.Propaganda bots vs. US-dominated bot traffic:Some speculated that propaganda accounts run via datacenter-controlled residential proxies would go quiet, citing fewer pro-Russia comments in Polish media. Others rejected this and pointed out that roughly 40-50% of bot traffic comes from US clouds like AWS, Google and Microsoft.
• Reddit science1Scientists fed people two 300-calorie meals with nearly identical carbs, fat, protein and salt. One was ultra-processed (deli turkey, instant mash, cookie, cereal), the other wasn't (egg, banana, cheese). The ultra-processed meal spiked insulin much higher for 2 hours. Processing itself may matter.A study in Nature Metabolism found that ultra-processed meals trigger different metabolic responses than minimally processed meals matched for calories and nutrients, including higher insulin, prolonged blood sugar, and altered fat and carb burning, possibly linked to brain reward cues.Meals weren't true analogues:Many argued the study compared entirely different foods (cookies, cereal vs. egg, banana) instead of processed vs. unprocessed versions of the same food, such as deli vs. roasted turkey. Critics called the design biased, though one user argued no cookie can be non-UPF.Carb types and food matrix matter:Users praised the crossover design and macro, fiber, and glycemic matching. However, they noted that sugar and starch subtypes and food structure weren't compared. Some said this shows "carbs" and nutrition labels are inadequate metrics, while others called the results obvious.What counts as ultra-processed?:Debate over whether cheese and craisins count as UPF. Users explained the NOVA system, which defines UPFs by industrial additives, and mechanical breakdown effects like instant vs. steel-cut oats. Many called the term vague and urged focusing on specific harmful processes.
