🏆 Featured this week

Here are our top recommendations this week. Watch now or bookmark!

1. “Keynote | KotlinConf ’26” from KotlinConf 2026

Conference ⸱ +20k views ⸱ May 21, 2026 ⸱ 01h 03m 34s

tldw: The KotlinConf ‘26 keynote in Munich opens with a clear theme: Kotlin is becoming a full ecosystem for backend, mobile, web, AI and multiplatform development, not just a language. Highlights include Kotlin 2.4 with stabilized context parameters and explicit backing fields, an 18-month security support policy for the standard library and an alpha release of an official Kotlin extension for VS Code. On the AI side, JetBrains is co-leading the new Agent Client Protocol for IDE-to-agent communication and shipping Junie, its coding agent, with dedicated Android support.

2. “Java AOT in Production at Netflix” from JavaOne 2026

Conference ⸱ +9k views ⸱ May 23, 2026 ⸱ 00h 49m 35s

tldw: Netflix used Project Leyden to dramatically improve startup time of critical services, but the JDK feature itself was only part of the story. The infrastructure they built around it is what made it work. Ian Brown, who leads Netflix’s Java Platform teams, and Martin Chalupa, Senior Software Engineer at Netflix, walk through the autoscaling problem that started the project, a primer on Leyden and ahead-of-time caches, how Netflix integrated the AOT archive into existing deployment pipelines, the lessons learned along the way and the measured results.

3. “Stop babysitting your agents... — Brandon Walsenuk, Unblocked” from AI Engineer Europe 2026

Conference ⸱ +8k views ⸱ May 26, 2026 ⸱ 00h 18m 54s

tldw: Same prompt, same agent, same model. Without a context engine: 2.5 hours, 20.9 million tokens and code that would have broken the entire system if it was deployed. With one: 25 minutes and a single nitpick before merge. Brandon Walsenuk from Unblocked argues the problem isn’t access but understanding: a context engine reasons across your codebase, Slack history, PR patterns and org structure...

4. “Introducing WebMCP: Agents in the Browser — RL Nabors” from AI Engineer Europe 2026

Conference ⸱ +3k views ⸱ May 23, 2026 ⸱ 00h 23m 08s

tldw: RL Nabors, a developer experience leader and alumna of the React Core Team and W3C, walks through MCP Apps, which bundle HTML, CSS and JavaScript into a single file rendered in an iframe by the agent, and WebMCP, which lets browser agents call your site’s existing functions directly using tool name and description attributes on forms you already have.

5. “Spring I/O 2026 Keynote” from Spring I/O 2026

Conference ⸱ +3k views ⸱ May 21, 2026 ⸱ 01h 08m 44s

tldw: The Spring I/O 2026 keynote in Barcelona brings together Juergen Hoeller, Rossen Stoyanchev, Oliver Drotbohm, Christian Tzolov and Josh Long for an overview of where the Spring ecosystem is heading. Expect Spring Framework 7 and Spring Boot 4, why the team recommends moving directly to JDK 25, Project Loom with virtual threads and structured concurrency, Spring Modulith and modern application architecture, plus Spring AI 2.0 with MCP support, agentic workflows and Java’s role in AI.

6. “Distributed Databases: What Could Possibly Go Wrong? - Heather Downing - NDC Sydney 2026” from NDC Sydney 2026

Conference ⸱ +1k views ⸱ May 22, 2026 ⸱ 00h 40m 25s

tldw: Scaling a database sounds like a great idea, until you start counting the ways it can fail. Add more nodes, throw in replication, and suddenly you’re explaining to stakeholders why two customers saw two different truths at the same time. Heather Downing, a Developer Advocate with deep experience across enterprise .NET and mobile, covers the fundamentals like replication, consistency and partitions, along with the tradeoffs nobody mentions when they say “just scale horizontally.”

7. “Coroutines vs. Threads: The True Cost of a Context Switch” from Android Makers by droidcon 2026

Conference ⸱ +100 views ⸱ May 22, 2026 ⸱ 00h 39m 44s

tldw: We’ve all been told coroutines are “lightweight” and threads are “expensive,” but what does that really mean at the OS and hardware level? This talk goes beyond the Kotlin APIs to explore the anatomy of a context switch: the syscall, the kernel trap, the scheduler saving registers and the resulting CPU cache invalidation, then contrasts it with the elegant user-space dance of a suspending coroutine.

8. “REST sends data across the network. What if it could send callable objects instead? | Kenton Varda” from JSNation 2026

Conference ⸱ +100 views ⸱ May 21, 2026 ⸱ 00h 28m 56s

tldw: REST APIs return data; Cap’n Web returns stubs: references to live objects on the server. That single shift changes everything about how you design APIs. Kenton Varda, lead engineer of Cloudflare Workers and creator of Cap’n Proto, shows why passing functions and objects by reference over the network isn’t just a nice DX improvement but a fundamentally different security model for AI agents. You’ll see TypeScript-native RPC that eliminates client libraries, promise pipelining that collapses three round trips into one without await, server-side lifecycle management that knows when the client is gone.

9. “Deploying HTTP/3 at Scale on Mobile: A 17% Startup Latency Gain Despite Implementation Constraints” from Android Makers by droidcon 2026

Conference ⸱ <100 views ⸱ May 24, 2026 ⸱ 00h 32m 12s

tldw: HTTP/3 promises better performance, but rolling it out at scale on Android exposes hidden trade-offs. The DeliveryHero engineering team deployed HTTP/3 across Android apps serving millions of users in 18 European and APAC markets, and used a randomized controlled experiment to measure a 51% reduction in connection handshake latency and up to 17% faster p90 home screen response times, alongside unexpected regressions on some secondary screens. The talk shares the full journey: from identifying last-mile mobile networking as the dominant performance bottleneck, through deployment, to diagnosing why some optimizations never materialized.

10. “We Built It for One. Then Everything Multiplied.” from Android Makers by droidcon 2026

Conference ⸱ <100 views ⸱ May 22, 2026 ⸱ 00h 42m 24s

tldw: When the team launched their Android banking app, it had one account, one portfolio and one currency, and the architecture was simple because the assumptions were simple. Then the business grew. This is the story of evolving into a multi-account, multi-portfolio, multi-currency platform without starting from scratch, told as a two-perspective narrative: one speaker covers the business drivers, the other the technical reality on Android (what broke, what scaled and what they’d do differently). You’ll leave knowing where single-account assumptions hide in your codebase and why complexity is multiplicative, not additive, when you stack these layers together.

11. “When ORM Becomes OMG: Performance Pitfalls in JPA and Friends | Jos Roseboom (EN)” from JCON EUROPE 2026

Conference ⸱ <100 views ⸱ May 26, 2026 ⸱ 00h 46m 50s

tldw: Jos Roseboom, founder of EasingYou, takes you on a tour of the common and not-so-common performance pitfalls that turn object-relational mapping into an object-relational mess. From data loading problems to connection mismanagement, he explores real-world issues using the FunFactStore: a sample app where fun facts are sold but bugs are free.

12. “Gents in the Monorepo: How we’re using LLM Coding Agents to tame a massive codebase at Stripe” from Codemotion Madrid 2026

Conference ⸱ <100 views ⸱ May 25, 2026 ⸱ 00h 41m 32s

tldw: Chris Ruiz from Stripe shows what happens when AI stops being an occasional helper and starts living inside a real enterprise-scale monorepo. The talk dives into how Stripe is using LLM coding agents to tackle one of modern engineering’s hardest problems: keeping an enormous codebase, full of legacy, internal conventions and historical decisions, under control. Chris walks through agent strategies already in production, from autonomous “minions” that handle simple tasks and produce review-ready pull requests from Slack, to Claude Code-based agents capable of executing multi-step migrations that require planning, research and coordination. He also covers how AI is helping dismantle frontend monoliths by guiding teams through the progressive removal of legacy patterns.

13. “Horacio Gonzalez - Rediscovering PHP: Modern Practices Beyond Legacy -” from Codemotion Madrid 2026

Conference ⸱ <100 views ⸱ May 25, 2026 ⸱ 00h 44m 29s

tldw: Horacio Gonzalez, Head of DevRel at Clever Cloud, invites you to rediscover the language from a modern angle and shows how PHP 8+ has become a mature, robust platform fully competitive with anything in today’s ecosystem. Expect JIT compilation, stricter typing, attributes and a tooling story built around Composer, the PSR standards, static analysis and dependency injection.

14. “Jesús Espino - Understanding 5 languages memory models (or most of them” from Codemotion Madrid 2026

Conference ⸱ <100 views ⸱ May 25, 2026 ⸱ 00h 36m 54s

tldw: Memory management is one of those things everyone uses daily but few really understand in depth. Jesús Espino, Principal Engineer at Ona and a veteran of open source projects like Taiga, Penpot and Mattermost, demonstrates how C, Rust, Python, Go and Java manage memory in radically different ways. The talk starts with what actually happens on the stack and the heap, then heads into trickier territory: garbage collection, mark-and-sweep, stop-the-world pauses and the machinery most of us use without ever seeing what runs underneath.

15. “Diana Cibu - How to handle over 1 trillion http requests/day: behind the scenes of ad tech industry” from Codemotion Madrid 2026

Conference ⸱ <100 views ⸱ May 25, 2026 ⸱ 00h 43m 48s

tldw: In modern ad tech platforms, scale isn’t a goal: it’s the starting point. Every second, these systems make millions of real-time decisions under brutal latency constraints, where a few milliseconds can directly impact revenue. Diana Cibu, DevLead at Criteo, takes you inside one of engineering’s most demanding ecosystems and walks through how systems handling over a trillion HTTP requests per day are designed and operated. You’ll follow an ad impression end-to-end, from page load to milliseconds-later decision, and see the distributed systems, queues and caches that make it look invisible.

16. “Dotan Horovits - Vector Search Made Simple: Getting Started with OpenSearch for AI Applications -” from Codemotion Madrid 2026

Conference ⸱ <100 views ⸱ May 25, 2026 ⸱ 00h 40m 28s

tldw: Dotan Horovits, OpenSearch Ambassador at AWS, is talking about moving to modern approach to search: from traditional lexical matching to vector search based on semantic similarity. The session introduces vector database fundamentals, shows how OpenSearch evolved into a platform that understands text, image and audio embeddings and walks through what it enables: semantic search, recommendation engines, visual search and systems that actually start to understand content.

17. “The European Startup Scene” from Software Engineering Daily

Podcast ⸱ May 26, 2026 ⸱ 00h 46m 54s

tldl: Europe’s startup ecosystem is maturing rapidly, with companies like Revolut, Lovable and Legora showing that world-class technology businesses can be built and scaled on the continent. The US still dominates venture-backed software with the largest markets, deepest capital pools and most ambitious exit culture, but a growing number of European startups are challenging that narrative. This Software Engineering Daily episode explores what’s actually different about the European scene and what it means for engineers and founders watching from either side of the Atlantic.

18. “Go for Java Programmers • Barry Feigenbaum & Shon Saliga • GOTO 2026” from GOTO Conferences

Podcast ⸱ May 21, 2026 ⸱ 0 days 00:32:30

tldl: Dr. Barry Feigenbaum, an IBM, Amazon and Dell veteran with decades of Java experience, spent time working with Go on microservices and liked it enough to write the book he wished had existed when he made the switch. In this GOTO Book Club episode with longtime colleague Shon Saliga, IBM Storage Evangelist, he walks through the core contrasts: Go is a compiled language that targets a narrower domain than Java but excels at command-line tools and web servers, with smaller binaries, faster startup and dramatically lower container overhead. Concurrency is the headline difference: goroutines are far lighter than Java threads and the channel-based communication model sidesteps many of the problems that make concurrent Java code hard to reason about.
