MARK ZUCKERBERG BLAMES SLOWER SALES ON WAR, LAYOFFS ON AI COSTS IN MEETING

Meta CEO Mark Zuckerberg addressed the market's negative reaction to the company's first-quarter results in a companywide meeting on Thursday. He said the 8% drop in Meta's shares was due to investor concern over an upward revision in expected capital expenditures and predictions of slower growth in the second quarter. He blamed the drop in Meta's ad business on the US war in Iran, as customers are spending less on discretionary things like advertising. Zuckerberg attributes the company's planned layoffs to a need to spend more on AI, and to reflect the greater speed and efficiency AI brings to workflows.

NO, REALLY, BASH IS NOT ENOUGH: WHY LARGE-SCALE CI NEEDS AN ORCHESTRATOR

While Bash scripts work for simple CI needs, they are not enough for complex, large-scale CI pipelines because they don't have inherent orchestration for parallel jobs, dependencies, and error handling. Mature engineering teams therefore require a dedicated CI orchestrator that provides job isolation, a comprehensive control plane for visibility, and structured primitives to define complex, distributed build pipelines.

FIREFOX MAKER TORCHES GOOGLE FOR BUILDING PROMPT API INTO BROWSER

Mozilla is against Google's decision to build AI plumbing into Chrome. The Prompt API gives web pages the ability to directly prompt a browser-provided language model. Mozilla says implementing the API results in severe negative consequences to interoperability, updateability, and neutrality of the web platform. The API is already being tested in Chrome and Microsoft Edge.
