I build RESTful APIs for a living. I've designed event-driven architectures, set up CI/CD pipelines, containerized applications on Azure, mentored junior developers. 7 years of this. Then I opened LeetCode and stared at a medium problem for 45 minutes and closed the tab. Working as a backend engineer for this long means you just never touch advanced DSA. My day to day is .NET, Azure, SQL, clean architecture. EF Core handles the data layer, Azure handles the scaling. I haven't needed to implement a graph traversal or think about tree balancing since university. So when I decided to start interviewing at bigger companies I figured I just needed a quick refresher. I studied this stuff in college. It would come back. It didn't. 7 years is a long time and most of it was gone. What I Tried I went through the usual options. LeetCode grinding. Jumping into random problems with no structure just kept reminding me how much I'd forgotten without actually helping me relearn any of it. YouTube. Watched hours of Abdul Bari, freeCodeCamp, various bootcamp videos. I'd finish a video convinced I understood it, then open my editor and draw a complete blank. Watching someone solve a problem and solving it yourself are not the same thing at all. Books. CLRS is great if your fundamentals are still intact. Mine weren't. None of these were bad resources. The problem was I kept jumping between them with no thread connecting them. A video here, a problem there, a random chapter somewhere else. After years away from this stuff I needed to go back to basics and build up properly, and nothing was set up for that. What Actually Helped Eventually I just mapped out what a proper learning order looked like and started going through it myself. Big O → Arrays → HashMaps → Linked Lists → Stacks & Queues → Recursion → Trees → Graphs → Dynamic Programming For me, order mattered. Going back to Big O first made Arrays click properly. Arrays made HashMaps make sense again. I couldn't get Trees to stick un

The company said this week it would comply with President Trump's voluntary AI executive order.

We've been running AI across a team for about two years. Expected the hard parts to be the models. They weren't. The problem that cost us most early on was context. We had a system making customer-facing recommendations without access to the business-specific knowledge it needed to answer accurately. Spent too long trying to fix it at the prompt level. The context layer didn't exist, and prompting didn't fill that gap, it just made it less obvious until something downstream failed badly enough to trace back to it. That failure pushed us to map the other places where AI builds break structurally rather than technically. We found five more, and they kept showing up across different stacks and different team sizes in roughly the same order. The first is identity, when you move from one person's AI to a team's AI, shared context without role-based permissions either creates noise or recreates the same knowledge silos you were trying to escape. The second is decision memory, records of what was decided aren't the same as memory of why, and that gap compounds quietly until a new team member gets a confident wrong answer from a system referencing reasoning that was abandoned months ago. The third is attention. Dashboards only work if someone looks at them, and the failure mode of every dashboard ever built is the same: critical things slip through when life gets busy. The fourth is write-back. Manual logging is a tax on the busiest moments, and the more important the work, the less likely anyone stops to document it. The fifth is governance, when the same agent that builds something also evaluates it, that's not a check, it's a loop grading its own homework. The sixth is economics, at solo scale AI cost is a rounding error, at team scale you're looking at a vendor invoice with no way to connect spend to specific workflows or outcomes. Which of these have you hit? And did they show up in this order or did something else surface first? If you're interested, we turned these i

LinkedIn’s Karthik Ramgopal and Prince Valluri discuss leveraging AI as a new execution model for large-scale engineering. They explain how to move beyond fragmented implementations by building platform abstractions for orchestration, structured context, and safe tooling like MCP. They share architectural insights from real-world coding, observation, and UI testing agents built at LinkedIn. By Karthik Ramgopal, Prince Valluri

The MacBook Neo is Apple's cheapest laptop, its most colorful, and its easiest to repair in years. That means owners can buy replacement parts in all four of its available colors and swap them in on their own. So that got us thinking: What if we bought a Neo just to see how funky we […]

Dropbox has unveiled Nova, an internal platform designed to orchestrate and operationalize AI coding agents across the company's engineering workflows. By Craig Risi

Netflix has shared details about Service Topology. This internal system creates and updates a live dependency graph for thousands of microservices. It helps engineers see how services connect and resolve issues more quickly. The system merges three separate data sources into a single, queryable graph. It updates almost in real-time as traffic patterns shift. By Claudio Masolo

Arm CPU cores, a powerful GPU and gobs of unified RAM? That sounds familiar!
