Show HN: A light GPT-5 vs. Claude Code comparison https://ift.tt/uTA8xim

Show HN: A light GPT-5 vs. Claude Code comparison Hi HN! Can’t believe I’ve been here over 12 years and this is my first Show HN. I guess this is two fold, One: I’m doing another startup! Charlie is an agent for TypeScript teams focusing heavily on augmentation. :) Two: Over the last week or so we put GPT-5 (through our Charlie Agent) head-to-head with Claude Code/Opus on 10 real TypeScript issues pulled from active OSS projects. Our Results GPT-5 beat Claude Code on all 10 case-by-case comparisons. Pull requests generated by GPT-5 resolved 29% more issues than o3. PR review quality rose 5% versus o3. Head-to-head case study We measured testability, description, and overall quality across 10 head-to-head PRs. Testability measures how thoroughly a code change is exercised by meaningful, behavior-focused tests. It considers whether tests are present and aligned with the diff, whether they explore edge cases and real-world scenarios, and whether they avoid vacuous, misleading, or implementation-dependent patterns common in code generated by LLMs. Description evaluates how clearly and accurately a pull request’s title and summary convey the purpose, scope, and structure of the code change. It emphasizes technical correctness, relevance to the diff, and clarity for future readers — penalizing vague, verbose, or hallucinated explanations often produced by code-generating agents. Quality assesses the substance and craftsmanship of the code change itself — judging whether it is correct, minimal, idiomatic, and free from hallucinated constructs. It emphasizes clarity, alignment with project norms, and logical integrity, while identifying agent-specific pitfalls like over-engineering, incoherent abstractions, or invented utilities. Testability: Charlie (0.69) vs Claude (0.55) Description: Charlie (0.84) vs Claude (0.90) Overall Quality: Charlie (0.84) vs Claude (0.65) Caveats Single-shot runs; no human feedback loop. Quality score uses a secondary LLM reviewer—subjective but transparent. Def looking for feedback on more evaluations we can do, also please do nit-pick the prompts, ideas, harness design etc etc. Tell us if this bar (CI + types) is the right one, or what you’d track instead. On a personal note: I’ve spent my career working on tools to help creators create, I’m extremely passionate about enabling people to do more easily. I am still somewhat uneasy about Gen AI, however I do believe the future is bright, certainly things are going to change - I would encourage you all to stay optimistic builders. Thanks for taking a look! https://ift.tt/cNDSQ0i August 8, 2025 at 12:26AM

Supporting Trips to School and Work: Muni Service Changes Start Aug. 30
By

Reducing crowding on the 49 Van Ness/Mission is one of our top priorities as we update service on a few routes later this month. We are changing Muni service on a few routes later this month to make it even easier to get to school and work in the morning. These changes are based on direct feedback from riders and operators. They aim to improve your Muni experience by: Addressing weekday crowding on routes used by students Expanding express service for downtown commuters Improving reliability and connections to key destinations including regional transit Weekend changes start Saturday, Aug. 30...

Show HN: Write lead sheets in a Markdown way and transpose in a second https://ift.tt/AxRDZep

Show HN: Write lead sheets in a Markdown way and transpose in a second Hey HN, I'm a software engineer with a passion for playing guitar. ( https://ivanhsu.co ) In the software industry, we use clever plain-text syntaxes like Markdown and Mermaid to handle complex layouts. This lets us focus on the content itself and quickly produce beautifully formatted documents. Isn't sheet music and chord charts just another form of documentation in the world of music? That's why I created Cord Land https://ift.tt/jL48nN3 ! It's a website where you can quickly generate lead sheets and draw chord charts using plain text. Even better, it can automatically transpose songs! Just write in one key, and it can be instantly converted it to any of the other 11 keys you want. I've implemented a new syntax called Corduroy, an extension of ChordPro syntax specifically designed for guitarists. Besides showing chord names above lyrics, you can also customize chord charts. For example, `%x32o1o%` will automatically draw a C major chord in the first position! Feel free to try it out here: https://ift.tt/nVKdD0z For more usage details, please refer to: https://ift.tt/qe5D3LS The name "Cord Land" comes from "Cord" and "Chord" being homophones, representing chords. Let's keep our passion for playing guitar alive, even after work! Ivan Hsu https://ift.tt/jL48nN3 August 3, 2025 at 08:08PM
