Zig Devlog: Self-Hosted x86 Back End Is Now Default in Debug Mode

Published: 2025-06-08 | Origin: Hacker News

This page summarizes recent changes to the Zig programming language's main branch, specifically focusing on updates from 2025. One significant change is that Zig will now use its own x86 backend by default for x86_64 targets, improving compilation speed dramatically—from 75 seconds to 20 seconds for larger projects like the Zig compiler—while also achieving better performance in behavior tests compared to the previous LLVM backend. The default setting for Windows hasn't changed yet due to pending COFF linker work. Future improvements are

The Looming Problem of Slow & Brittle Proofs in SMT Verification (and a Step Toward Solving It)

Published: 2025-06-08 | Origin: /r/programming

Automated formal verification tools like Dafny and Viper are gaining traction in industries such as AWS and Microsoft for verifying safety-critical software. However, as these tools are applied to larger codebases, issues like slow and brittle proofs are becoming apparent. Proof brittleness occurs when verification times become inconsistent, and minor changes in the code can unexpectedly lead to failed verifications, often due to dependencies on irrelevant program features within the SMT solver. This has prompted developers to invest significant effort in mitigating these issues, but

Why Android can't use CDC Ethernet (2023)

Published: 2025-06-08 | Origin: Hacker News

The content discusses the process of finding compatible USB Ethernet adapters for Android devices. It explains that Android supports USB Ethernet adapters but emphasizes the importance of selecting an adapter with a compatible chipset. Unfortunately, manufacturers rarely publish compatibility lists, so users often have to rely on anecdotal evidence from forums or buy adapters sold as accessories by the manufacturer. To understand which adapters are supported, one can examine the device's kernel configuration, as this configuration indicates the features and hardware supported by the kernel. The post also mentions the

<Blink> and <Marquee> (2020)

Published: 2025-06-08 | Origin: Hacker News

The article discusses the HTML `<blink>` and `<marquee>` tags, which were popular in the 1990s but are now largely forgotten by younger developers. The creation of the `<blink>` tag is attributed to Lou Montulli, a developer who was part of the Netscape team. He claims that while he did not directly write the code, his joke about a text element that would work in both graphical and text-only browsers inspired another engineer to implement it during a late-night coding session.

Every AI coding agent claims "lightning-fast code understanding with vector search." I tested this on Apollo 11's code and found the catch.
