TLDR # Observability at scale: Our internal system grew from 19 PiB to 100 PB of uncompressed logs and from ~40 trillion to 500 trillion rows. Efficiency breakthrough: We absorbed a 20× surge in event volume using under 10% of the CPU previously needed. OTel pitfalls: The required parsing and marshalling of events in OpenTelemetry proved a bottleneck and didn’t scale - our custom pipeline addressed this.

Microsoft's Family Safety Feature Is Blocking Chrome: Here's the Workaround

cnet.com See Full Bio 2025-09-21 15:44:00

Microsoft's Family Safety feature is designed to block certain types of websites from children. Apparently, it's also been blocking Google's Chrome browser -- but there is a workaround. Chrome, a web browser launched by Google in 2008 -- is not working when users have the Family Safety Feature enabled. The first report of the bug seems to date to June 3, when a user posted on Google's online support board. The user noted that Chrome constantly closed when the person tried to use it. Restarti

Drinks in glass bottles contain more microplastics than those in other container

news.ycombinator.com Unknown 2025-09-21 21:01:34

The aim of the ANSES study was to determine the level of microplastic contamination in drinks such as water, soda, iced tea, wine and beer; it also sought to establish the impact of their containers on this level. For most of the drinks studied, the level of microplastics was found to be higher in glass bottles than in other containers. For example, on average, in glass bottles of cola, lemonade, iced tea and beer, there were around 100 microplastic particles per litre. This number was five to 5

Cracovians: The Twisted Twins of Matrices

news.ycombinator.com Unknown 2025-09-21 19:35:05

Linear algebra is typically explained using matrices. But matrix theory is just one possible perspective. Below, I describe an alternative approach to linear algebra. Tadeusz Banachiewicz (1882–1954), a Polish astronomer living in Krakow, was passionate about calculating machines. From the 1920s, Banachiewicz developed a method for computations on tables of numbers, which was particularly easy to perform with arithmometers. In honor of Krakow, Banachiewicz named these computational objects crac

Having trouble opening Chrome? It may be Microsoft’s fault

androidauthority.com Unknown 2025-09-22 05:13:29

Rita El Khoury / Android Authority TL;DR A bug is preventing Windows users from opening Google’s Chrome browser. The bug is connected to Microsoft’s Family Safety feature. There are a few workarounds, like renaming Chrome.exe to Chrome1.exe. Microsoft isn’t afraid to deploy tactics to nudge you away from Chrome. For example, earlier this year, Bing users were running into a pop-up that discouraged them from switching browsers. However, the friction between the two isn’t always intentional, w

iOS 26 to let third-party apps build their own AirDrop alternative

Not content with a real estate empire and the presidency of the United States, the Trump family is wading into the phone wars like it's 2011 with a shiny gold monstrosity called the T1, the marketing of which leans extensively on the narrowest idea of patriotism. Beyond the immediate question — why do this, like, at all? — the T1 invites a question that's perhaps easier to interrogate: How can any modern smartphone claim to be made in the US?

Again, I don't want to minimize the real harm. But it is not a shark hunting you because it has a taste for human flesh. They don't have hands. Th
