1. Python 3.15’s interpreter for Windows x86-64 should hopefully be 15% faster
Total comment counts : 22
Summary
The author revisits tail-calling CPython performance across two platforms. On macOS AArch64 (XCode Clang), tail-calling interpreters are about 5% faster than computed-goto counterparts on pyperformance. On Windows x86-64 (experimental MSVC), tail-calling yields roughly 15–16% speedups, with a wide range (some benchmarks up to ~60–78% faster, a few slower). Results are experimental for MSVC, but largely positive overall; larger libraries like xDSL show ~14% gains. The post notes ongoing plans to ship macOS 3.15 binaries with tail calling, while cautioning stability and experimental status on MSVC.
Overall Comments Summary
- Main point: The discussion centers on CPython’s potential tail-call based interpreter loop, its MSVC vs GCC/Clang compatibility (noting the need to attach certain attributes to the function declarator), and the anticipated cross-platform performance implications.
- Concern: The main worry is that reported results may be non-replicable or non-portable, requiring cross-compiler verification and audits, with MSVC-specific features risking long-term portability issues.
- Perspectives: Opinions range from cautious optimism that tail-call techniques could improve interpreter performance and align with CPU branch predictors, to skepticism that such micro-optimizations are the right path and that robust, cross-compiler benchmarking or alternative approaches like JIT are needed.
- Overall sentiment: Mixed

4. Archiving Git branches as tags
Total comment counts : 3
Summary
Summary: A clever git alias archives old branches by converting them into tags, reducing visibility in tooling. It also enables tab completion for selecting a branch to archive by wrapping the alias in a self-invoking bash function and using a : git switch hint so the completion mirrors git switch. This relies on the official git-completion script; zsh’s default completion lacks the needed style, so the official version must be loaded. On macOS with Xcode git, you can link and source the completion under zsh. Credit to a Reddit thread.
Overall Comments Summary
- Main point: The discussion centers on how to archive branches in Git, weighing a tag-like snapshot approach against keeping branches and using practical workflows (headless remotes, git push –all, ar/ prefixes, and git notes).
- Concern: The main worry is that archiving branches may be niche or unnecessarily complex, with potential issues around managing refs, pointer updates, and recoverability.
- Perspectives: Participants range from endorsing archiving branches as sensible to questioning its usefulness as niche, while suggesting alternatives like headless remotes, full remote backups via push –all, ref prefixing, and recording metadata with git notes.
- Overall sentiment: Mixed
5. I sell onions on the Internet (2019)
Total comment counts : 24
Summary
Vidalia onions are a mild, sweet variety some eat like apples. The narrator, a web professional, isn’t a farmer. In 2014 the domain VidaliaOnions.com expired; he backordered it and won a bid around $2,200. He treats domains as living inspirations—Faulkner’s idea that characters write themselves—and let the domain guide the business. Rather than rushing an idea, he pursued a farm-to-door Vidalia concept, despite lacking farming or logistics. Starting February 2015 with profits from other domains, he connected with the Vidalia Onion Committee, partnered with Aries Haygood’s 25-year farm with a packing shed and award-winning Vidalia, to grow and ship Vidalias.
Overall Comments Summary
- Main point: [The discussion centers on treating domain-name projects as real businesses that the domains themselves drive, using Vidalia onions as the leading example.]
- Concern: [The main worry is spending money on domains without a clear, sustainable plan, risking hype over tangible product-market fit.]
- Perspectives: [Viewpoints range from enthusiastic, domain-led entrepreneurship that yields practical outcomes, to cautious skepticism about hype and speculative spending, with anecdotes highlighting both successes and missteps.]
- Overall sentiment: [Mixed]
6. Show HN: Lamp Carousel – DIY kinetic sculpture powered by lamp heat (2024)
Total comment counts : 3
Summary
These are homemade “can spinners” cut from recycled soda cans that spin on a sharpened pivot wire near a heat source like a lamp. Steps: sharpen a pivot wire for low friction; fashion a central dimple; cut and shape blade pieces (sidewalls or can bottoms); trim for balance; attach the wire to the lamp’s harp or shade nut. Incandescent bulbs work best, LEDs after warming. Thinner sidewall aluminum develops tiny pinholes with the pivot; bottoms are sturdier. A gallery shows designs like Turbine, Propeller, Flying Wing, etc.
Overall Comments Summary
- Main point: The thread discusses a heat-powered spinning Christmas decoration project, praising the “dad turbine” and flying wing designs and their potential to be added to heat-emitting lamps or candles.
- Concern: The main worry is feasibility, since many lamps today do not emit enough heat to drive the mechanism.
- Perspectives: Viewpoints range from enthusiastic admiration for the designs to practical caution about heat output and real-world applicability.
- Overall sentiment: Mixed

8. Asahi Linux with Sway on the MacBook Air M2 (2024)
Total comment counts : 9
Summary
Bought a MacBook Air M2 (16GB RAM, 256GB SSD, 13.6”) for about $750. Asahi Linux isn’t fully supported yet, so the author runs Fedora minimal with Sway, later switching to Waybar for visuals. They customized the notch (56px) and top bar to balance usability, updating battery info and keeping a mostly keyboard-driven workflow. Asahi Linux is very smooth; the touchpad is excellent. They used the Alkeria ARM64 SDK via a .deb, couldn’t get alien to work (arm64/aarch64 mismatch), so extracted with bsdtar. External 4TB Crucial X8 handles line-scan data. Battery life ~4.5 hours under heavy use.
Overall Comments Summary
- Main point: The discussion centers on the viability of running Asahi Linux on Apple Silicon and the broader Linux-on-laptops landscape, including performance, battery life, and future M-series support.
- Concern: The main worry is battery drain in sleep mode, uncertain future Apple Silicon support (M3/M4), and hardware constraints (e.g., minimum SSD size) affecting Linux usability.
- Perspectives: Viewpoints vary from praise for Asahi Linux’s responsiveness and desire for Linux parity with Mac hardware to concerns about hardware limitations, driver inefficiencies, and uncertain future support.
- Overall sentiment: Mixed
9. Alzheimer’s disease can be reversed in animal models? Study
Total comment counts : 15
Summary
Researchers from Case Western Reserve University, UH, and the Cleveland VA showed restoring brain energy balance by preserving NAD+ levels can prevent and reverse Alzheimer’s pathology in mouse models and align with human AD brain data. In two genetic AD mouse models (amyloid and tau), NAD+ decline was pronounced; treatment with the NAD+-balancing drug P7C3-A20 prevented disease and, when started after advanced pathology, enabled cognitive recovery and normalization of phosphorylated tau 217 levels. Findings suggest a paradigm shift toward recovery-focused AD therapies, though caution is advised with NAD+-precursor supplements.
Overall Comments Summary
- Main point: Restoring brain NAD+ balance with the small molecule P7C3-A20 reportedly reverses advanced Alzheimer’s pathology and restores cognition in two mouse models, fueling both optimism and controversy about human translation and commercialization.
- Concern: The main worry is that results in mouse models may not translate to humans, and issues like potential conflicts of interest, lack of human toxicity data, and overstating “full neurological recovery” undermine reliability.
- Perspectives: Viewpoints range from cautious optimism about a new therapeutic direction to strong skepticism about model validity, mechanism interpretation, and the risk of hype without robust human data.
- Overall sentiment: Cautiously skeptical
10. Phoenix: A modern X server written from scratch in Zig
Total comment counts : 36
Summary
Phoenix is a new Zig-written X server (not Xorg) designed as a modern alternative. It’s not production-ready; it can render simple GLX/EGL/Vulkan apps nested inside an existing X server, the only supported mode until ready. It uses a compact X11 subset for modern apps (still supports GTK2) and targets newer hardware (last 15–20 years) with drm/mesa gbm; no server driver interface. It emphasizes safety with automatic protocol parsing, ReleaseSafe builds, and default process isolation with permission prompts. It supports multiple monitors, VRR, HDR, no tearing, and a built-in compositor (disabled with fullscreen). Build with Zig: zig build; binary at zig-out/bin/phoenix.
Overall Comments Summary
- Main point: The thread discusses Phoenix, a new project proposing a Wayland-like, merged display server and compositor intended as an X11 replacement with a focus on security and accessibility.
- Concern: The main worry is whether it will achieve broad adoption and maintain compatibility and accessibility without fragmenting the ecosystem.
- Perspectives: Views range from enthusiastic optimism about a modern, secure alternative to X and Wayland to skepticism about feasibility, naming conflicts, and the project’s ability to displace established stacks.
- Overall sentiment: Mixed
