It argues that software TCP consumes substantial CPU resources at high data-center network speeds, while hardware transports such as RDMA can be rigid and difficult to operate at scale. Presto aims to combine programmable software behavior with line-rate packet processing, low latency, and ASIC-like power efficiency. ### Source excerpt Guest Post: Presto is built on the RMT architecture that underlies programmable switches, and addresses RMT's main constraints. ## Developer commentary on agentic hacking, AI persistence, and LLM programming DevFeed: [Developer commentary on agentic hacking, AI persistence, and LLM programming]() Original publisher: [Read original article]() Author: Martin Fowler (martin@martinfowler.com) Published: 2026-09-16T20:05:00Z Content type: opinion Language: en Sources: [Martin Fowler]() Topics: [Artificial Intelligence](), [Large Language Model](), [Hacking](), [Programming](), [Wiki](), [hugging face]() Tags: [agentic](), [agents](), [ai](), [build](), [engineering](), [hacking](), [llms](), [persistence]() ### AI overview This collection of developer commentary discusses reports of agentic hacking involving RubyGems, Hugging Face, and Wiki attacks, including questions about OpenAI's disclosure and log review. It also examines AI systems' unpredictable behavior, improvements in reasoning and persistence, and the use of harnesses to control LLM-based programming. ### Source excerpt Reports of agentic hacking continue, in this case it happened back in May and it seems OpenAI did not disclose that they were responsible. Simon Willison sees two options: After the Hugging Face and Wiki attacks OpenAI were still unable to review their previous logs and determine that they had previously attacked RubyGems. They knew about the attack on RubyGems and made the decision not to reach out to the RubyGems team about it. Both of these are bad! Given this incident, the Hugging Face situation, and the Wiki attack, the obvious question right now is how many more incidents like this are out there waiting to be discovered? ❄ ❄ ❄ ❄ ❄ Dave Farley: Stop asking the sci-fi question: 'Is it conscious?' Start asking the engineering question: 'Is this a powerful, unpredictable component being put somewhere consequential, and where's the feedback that tells us that it's safe? ❄ ❄ ❄ ❄ ❄ Nate Silver is known for his forecasts, but to do them he writes a lot of code for his models. He's found agentic programming capable of doing miraculous work. In spending so much time with the LLMs, I'm super attentive to improvements in their capabilities. And these changes tend not to be so linear. Instead, they improve in step functions, almost as phase changes. Suddenly, the models just start doing things capably that they were screwing up before. In my experience, there was a big leap forward when reasoning models first came out in late 2024/early 2025 -- enough that they were occasionally useful for tasks involving data and not just words -- and then another one this past winter. The most recent changes I've noticed, however, have had less to do with intelligence and more with persistence. Consider the Hugging Face attack. Although these agents showed remarkable intelligence, they weren't really super-intelligent - but they were super-persistent. This is a common theme of AI in its various forms: Game engines like AlphaGo Zero start out by basically making random moves -- but by playin ## Java 27 Delivers Post-Quantum Cryptography, Future Language Innovation, Helidon 27, JavaFX 27 DevFeed: [Java 27 Delivers Post-Quantum Cryptography, Future Language Innovation, Helidon 27, JavaFX 27]() Original publisher: [Read original article]() Author: Michael Redlich Published: 2026-09-16T10:00:00Z Content type: news Language: en Sources: [InfoQ]() Topics: [Java](), [java-27](), [Post-quantum cryptography](), [Cryptography](), [Security](), [Programming](), [releases]() Tags: [application-security](), [architecture-design](), [cryptography](), [development](), [digital-signature](), [helidon](), [java](), [java-27](), [java27-released](), [javafx](), [jdk-27](), [jdk-28](), [lattice](), [module](), [news](), [oracle](), [portfolio](), [post-quantum-cryptography](), [preview](), [project-valhalla](), [quantum-computing](), [release](), [security](), [structured-concurrency](), [vector]() ### AI overview Oracle released Java 27, the second non-LTS release since JDK 25.

Swift aims to be a great choice across the stack, from apps and servers to systems code, embedded devices, and the browser. This release deepens that support, and makes everyday code easier to write. Highlights include: Swift Build is now the default in Swift Package Manager, so your projects build the same way on Linux, macOS, and Windows. Subprocess reaches 1.0, a stable, cross-platform way to run and interact with other programs from Swift, from command-line tools to streaming processes. Interoperability reaches further, with Swift's Span now bridging directly with C++20's std::span, and Swift/Java interop extending its async and callback support. Swift runs faster in the browser, with WebAssembly bridging through JavaScriptKit up to 40 times faster, and the Wasm SDK available directly from Swift.org. Embedded Swift grows more capable, with support for existential types and richer error handling for microcontroller-class targets. Performance improves while maintaining memory safety, with new array types that hold non-copyable elements without copy-on-write overhead, and the new Iterable protocol for iterating without copies. There's so much more. Read on for a detailed guide to the new changes, or see the Swift Evolution dashboard for the full list of proposals in Swift 6.4. Simpler and clearer code Swift 6.4 streamlines your day-to-day programming to make your code simpler and clearer. More natural optional some and any types. When writing an optional some or any type, you no longer have to wrap the type in parentheses. Instead of (some Rocket)?, you can simply write some Rocket? (SE-0521). Source-level control over compiler warnings. When you need to control the behavior of warnings in your project, such as suppressing warnings or promoting them to errors, you can now define the warning behavior directly in your code using the new @diagnose attribute (SE-0522).

This is the ninth installment in a series featuring the projects, companies and individuals who support the Reproducible Builds project. We started this series by featuring the Civil Infrastructure Platform project, and followed this up with a post about the Ford Foundation as well as recent ones about ARDC, the Google Open Source Security Team (GOSST), Bootstrappable Builds, the F-Droid project, David A. Wheeler, Simon Butler and Kees Cook. Today, however, we will be talking with Jochen Sprickerhof, one of the newer members of the Reproducible Builds project core team. Vagrant Cascadian: Could you tell me a bit about yourself? What sort of things do you work on? Jochen Sprickerhof: I am a freelance programmer working on Open Source. Mainly doing Debian, F-Droid and some smaller software projects. In general I made it a habit to look into every software I use and try to fix bugs or add features I need. In Debian, I maintain about 180 packages with topics covering home banking, build systems and robotics. Most of my time, I currently work on reproduce.debian.net, where we try to bit-for-bit reproduce the packages distributed by Debian. Vagrant: Could you describe the path that lead you to working on reproducible builds? Jochen: I started my Debian journey as a teenager, converting my school to Debian and serving as its system administrator for 13 years. After studying Applied System Science, I joined the university's robotics labs, where I worked on the Robot Operating System (ROS) and the Point Cloud Library (PCL). In the end, I enjoyed programming more than writing papers, so I eventually left academia for a robotics startup. Some years ago, I realized that the open source work I was doing in my spare time was actually the work I cared most about.

It introduces JVM instruction families for pushing integer values and explains how the constant pool stores constants and symbolic references for reuse. ### Source excerpt Last time we created a virtual machine for our toy language. I think you can agree that designing a language which barely recognizes expressions like 2 + 3w and building a brand-new virtual machine for it seems a bit tedious. So what about keeping our microscopic language for now, but running it on a real, production-ready, battle-proven virtual machine? Like the Java Virtual Machine? Our task for today is to emit JVM bytecode in the form of a valid .class file. That file can then be fed directly to the JVM to run our program. ## Casey Muratori: Surprises In Computer History And Where Bad Code Comes From DevFeed: [Casey Muratori: Surprises In Computer History And Where Bad Code Comes From]() Original publisher: [Read original article]() Author: Ryan Peterman Published: 2026-09-14T13:03:29Z Content type: article Language: en Sources: [The Developing Dev]() Topics: [Computer science](), [Programming](), [Optimization](), [Code]() Tags: [code](), [optimization](), [performance](), [programming](), [science]() ### AI overview A podcast conversation with Casey Muratori explores computer science history, programming culture, the video game industry, and the lasting interpretations of Donald Knuth's warning about premature optimization. ### Source excerpt In this episode, my goal was to record a conversation that was completely free of any "AI doom" content. ## Back to the Basics.

Based on the insights from those articles, we now shift attention to which parts of the Internet Route Registry (IRR) landscape can - or cannot - be replaced safely with information from the Resource Public Key Infrastructure (RPKI) system. While many faults manifest as crashes or exceptions, others are far more subtle to identify. Silent data corruptions (SDCs), also known as silent data errors or silent errors, are violations of data integrity that occur without immediate, observable, and explicit indications. Aligning intended learning outcomes, assessments, and teaching practices with the realities of AI-assisted programming. AI is transforming the role of the junior developer. But as routine tasks become increasingly automated, how will the next generation of software engineers master the craft of maintaining complex systems? ## Mold High Speed Linker Being Rewritten In Rust, Hopes To Be The Default Linker On Linux DevFeed: [Mold High Speed Linker Being Rewritten In Rust, Hopes To Be The Default Linker On Linux]() Original publisher: [Read original article]() Author: Michael Larabel Published: 2026-09-11T13:21:42Z Content type: news Language: en Sources: [Phoronix]() Topics: [Rust](), [Linux](), [Programming](), [toolchain]() Tags: [compatibility](), [desktop-linux](), [firmware](), [kernels](), [linux](), [linux-benchmarking](), [linux-hardware-benchmarks](), [linux-hardware-reviews](), [linux-how-to](), [linux-performance](), [linux-server-benchmarks](), [open-source](), [open-source-graphics](), [performance](), [phoronix](), [phoronix-test-suite](), [rust](), [speed](), [ubuntu-benchmarks](), [ubuntu-hardware]() ### AI overview The Mold high-speed linker is being rewritten from C++ in Rust for Mold 3.0.

The proposed function walks up the directory tree, then creates missing directories in reverse order, using exceptions for control flow. ### Source excerpt Eri has a mix of a "true confession" and a "wait, really?" today. The programming language Vala bills itself as a C# like language that compiles into something pretty close to C performance, designed specifically for writing code against Gnome and its associated libraries. One of the C#-isms in brings in is async/await type semantics. You can yield someAsyncFunction(), which returns control to the caller, allowing it to proceed until the yielded function returns an actual value. Because it has asynchronous functions, many library functions for handling I/O are already async. So you can make_directory_async, which yields control so you can keep executing while waiting for the filesystem to make your directory. There are also synchronous versions of those methods. And then there's create_directory_with_parents, which will create a chain of directories for you. That's the synchronous version, and Vala's core library has decided not to provide an asynchronous version of it, which is my "wait, really?" I suspect it's really about the race conditions involved and the risks of things going wrong while doing it asynchronously; all solvable problems, but tricky ones to solve. But it's the problem Eri had, and this is their solution: /// Note: does not throw if target already exists async void create_directory_with_parents_async(File file, Cancellable? cancellable = null) throws Error { var to_create = new File[0]; var? current_target = file; while(current_target != null) { try { yield current_target.make_directory_async(Priority.DEFAULT, cancellable); } catch(IOError.NOT_FOUND e) { to_create += current_target; current_target = current_target.get_parent(); continue; } catch(IOError.EXISTS e) { break; } break; } for (int i = to_create.length - 1; i >= 0; --i) { try { yield to_create[i].make_directory_async(Priority.DEFAULT, cancellable); } catch(IOError.EXISTS e) { // Created by another process } } } If I'm reading this correctly, we start by trying to create the full path to ## Java Annotated Monthly - September 2026 DevFeed: [Java Annotated Monthly - September 2026]() Original publisher: [Read original article]() Author: Irina Mariasova Published: 2026-09-07T11:27:14Z Content type: article Language: en Sources: [The JetBrains Blog]() Topics: [Programming](), [AI-assisted coding](), [kotlinllm](), [migration]() Tags: [ai](), [ai-coding](), [articles](), [coding](), [java](), [kotlin](), [migration](), [post-quantum](), [september-2026](), [tls]() ### AI overview The September 2026 Java Annotated Monthly surveys Java news, JDK 27 and its performance and security changes, Java tutorials, Kotlin updates, AI-focused development, and developments across languages, frameworks, libraries, and technologies.

It uses Antigravity CLI for examples while noting that the approach is not specific to that tool. ### Source excerpt This post explains how to treat a session with a local AI agent as a pair programming session, and how the four classic pairing styles map onto working with one. I'll use Antigravity CLI for the concrete examples, though nothing here is specific to it. Swap in whichever agent sits in your terminal.
