TypeSafe AI's Jev offers a cheaper alternative to using generative AI for routine decisions, reviving classification techniques with modern pretrained models.

I've been noticing how while there's a lot of appreciation for backend distributed systems challenges, there's a lot less empathy for why mobile development is hard when done at scale. Building a backend system that serves millions of parallel customers means building highly available and scalable backend systems and operating these reliably. But what about the mobile clients for these systems?See MobileAtScale.com for more details on the contents of the book.ContentsBuilding Mobile Apps at Scale: 39 Engineering ChallengesPART 1: Challenges Due to the Nature of Mobile Applications 1.

During my time at Uber, I've helped with 10+ mobile engineering promotions in my org, 3 of these to above senior levels.

Welcome back to KCD Around the World, a series where we explore Kubernetes Community Days from every corner of the globe. Behind every event is a community of volunteers, contributors, organizers and attendees who make it all happen. Through conversations with the people behind each KCD, we share what makes it unique. This stop: Sofia, Bulgaria. On Tuesday, September 29, 2026, the second KCD Sofia takes place at Sofia Event Center. We spoke with three of its organizers, Yoana, Spas, and Orlin, about building a meeting point for Bulgaria’s cloud native community and what goes into running it for a second year.

Advanced Micro Devices soared past $1 trillion ‌in market capitalization for the first time on Monday, joining a small group of chipmakers to reach the milestone, as investors bet on its expanding role in AI computing.

Having played both parts in the kabuki play that is employee-employer matchmaking, I feel the way we play it is a zero-sum game. I wish it were not so. When this post started life in 2024, as a wall of text chat message, it was brutal out there, on both sides of the software industry interview table. The ZIRP had ended. As of 2026, post-ZIRP reality has properly set in and remains bad ("AI" is a Fig Leaf (Enterprise Edition) for structural damage they self-inflicted, and if you look at Hyperscaler GPU depreciation schedules, they are making it order-of-magnitude worse). Set to that backdrop, here is a hopefully hopeful hiring anecdote where I think we avoided the so-called "Secretary Problem", framed within Optimal Stopping Theory. It can be done. Non-zero-sum hiring ought to be default-mode for any industry, AI or no AI.
