• How Google migrated billions of lines of code from Perforce to Piper — As of 2011, the single server had been in operation for the past eleven years of Google history. It had served Google the two-year-old startup, and had now scaled to support Google the public company. In fact, around that time, a lucky Google engineer had just snagged PR #20,000,000.

• Apple’s Longer-Lasting Devices, iOS 19 and Apple Intelligence on the Vision Pro — Apple’s strategy to make its devices last longer will mean AI and software are even more important to its business.
• Apple may charge “monthly fees” for advanced Apple Intelligence features — “Though Apple Intelligence will be free to start, the long-term plan is to make money off the capabilities,” said the report. “The company could eventually launch something like Apple Intelligence+ — with extra features that users pay monthly fees for, just like iCloud,” it added.

Apple already takes a cut of subscription revenue from any AI partner it brings on board. "The company will be less reliant on hardware tweaks to drive its business and will actually be making money from AI — something everyone in Silicon Valley is hoping to pull off," Gurman says.
