    Cursor + V0: Can We Build An AI Next.js App in 8 Minutes?
    https://www.youtube.com/watch?v=zyqwt65NIgs

    In this video, I’ll show you how to build a simple AI application using Cursor, v0 by Vercel, combined with a background removal model from fal.ai. We’ll start by setting up the background removal model, referencing API documentation, and creating a new Next.js project. Along the way, I’ll demonstrate how to integrate an image uploader and process images with the Fal hosted model. I’ll also highlight the Composer view in Cursor, which helps streamline our coding process by referencing documentation and making file tweaks efficiently. By the end, you’ll see how to add features like image downloading and full-screen view, making this a practical and easy-to-follow tutorial.

    What is LLVM: How It Powers Modern Compilers and Optimizes Code
    https://www.youtube.com/watch?v=3WojCM9r0Ls

    Explore the inner workings of LLVM, the powerful framework behind many modern compilers! In this video, we break down key concepts like Intermediate Representation (IR), LLVM’s modular design, and Just-In-Time (JIT) compilation. You’ll learn how LLVM supports multiple languages, optimizes code with techniques like dead code elimination and loop unrolling, and generates machine code for different architectures. We also look at Clang, LLVM’s popular C/C++ front-end, and the complete workflow from source code to optimized machine code.

    GraphQL vs REST: Which is Better for APIs?
    https://www.youtube.com/watch?v=PTfZcN20fro

    If you’re a developer, you’re probably familiar with REST APIs, but there’s another query language for APIs that you should add to your programming toolkit: GraphQL. In this video, Martin explains the two different approaches these frameworks take for building APIs and compares their strengths and weaknesses. Spoiler alert: It’s not an either/or choice, and it’s worth knowing both approaches and applying them where it makes the most sense.

    Building an open source control plane for data
    https://www.youtube.com/watch?v=gTwho9ijc-8

    Today’s data landscape, spanning operational, streaming, lakehouse, and warehouse systems, grapples with the complexities of decentralization. Do you seek new approaches, tools, and solutions to address challenges in data discovery, management, governance, quality, and observability?

    How about a visibility layer, or control plane, for the data distributed across your stack?
    In this session, Shirshanka Das, founder of the open source DataHub Project, will describe how a control plane for data, powered by metadata, can simplify data discovery, foster team collaboration, and offer real-time observability into data assets.
    This talk will cover:
    The control plane for data and its role in the decentralized data stack
    Using the open-source DataHub Project to implement the control plane for data
    How data contracts help you define and enforce decentralized governance
    How this helps reduce operational overhead and keep cloud costs down
    Why the industry is gravitating towards these ideas—and why the DataHub Project is key

    Comment:
    This reminded me of the time a colleague thought he could rewrite his C code in assembly to get more performance, what he learnt at the end was that the C compiler optimisation was much better than his assembly coding skills.

    2024-10 WebAssembly and Java
    https://www.youtube.com/watch?v=GrhZY5SlJwE

    WebAssembly is the exciting technology that allows you to program for the web in languages other than JavaScript. There’s been a lot of hype surrounding it, with some speculating that it could not only replace JavaScript, but it could replace Java virtual machines as well. Some people are even trying to use WebAssembly for cloud computing and have suggested that it could actually replace Docker.

    Come for an overview tour of WebAssembly and the WebAssembly ecosystem where we try to discover how much of this hype is justified.

    The talk will look at how WebAssembly differentiates itself from Java bytecode, despite the conceptual similarities between the two. We’ll try to understand the WebAssembly security sandbox and compare it to other ways of sandboxing your code. We’ll examine the rationale for running WebAssembly on the server, and briefly touch on how to run WebAssembly code from inside your Java programs. Finally, the talk will discuss why Java programmers aren’t using WebAssembly despite the fact that browsers have supported it since 2017, and it will discuss why that might change in the future.
