New ask Hacker News story: Stronk.app – open-source gym lifts journal

Stronk.app – open-source gym lifts journal 14 by apatheticonion | 4 comments on Hacker News. Hey all, didn't want to pay for Strong or Heavy so I started building my own lifts journal app. It's free and always will be. https://stronk.app Source Code (open to contributions). If you find bugs, add it to the issues. If you don't use it now but plan to after I build out the features, please star the project so I know to keep working on it. https://ift.tt/7Zq1hOS There a lot to do still, gotta add things like; - Strava/Facebook Sync - Import/Export - Charts - Set type (warmup/drop) - Timers - Online backups (right now it's saved to your phone) It's a web app because I'm not paying Apple and Google to publish it on the app store.

Ask HN: What did you lose forever because you had no backup? 6 by postit | 1 comments on Hacker News. A friend and I were talking about a DOS POS system we wrote decades ago. It was crude, handwritten using Turbo Pascal DBF files and somehow still running in a few places since it got pirated. We no longer have the source. No install disks. No backups. The software survived longer than our memory of it. It made me realize how often "temporary" work outlives its creators, while the source vanishes. What’s the most important thing you lost because you assumed you’d back it up later? Code, data, research, art, configs, anything. Did that loss permanently change how you handle backups?

New ask Hacker News story: Why are we accepting silent data corruption in Vector Search? (x86 vs. ARM)

Why are we accepting silent data corruption in Vector Search? (x86 vs. ARM) 4 by varshith17 | 1 comments on Hacker News. I spent the last week chasing a "ghost" in a RAG pipeline and I think I’ve found something that the industry is collectively ignoring. We assume that if we generate an embedding and store it, the "memory" is stable. But I found that f32 distance calculations (the backbone of FAISS, Chroma, etc.) act as a "Forking Path." If you run the exact same insertion sequence on an x86 server (AVX-512) and an ARM MacBook (NEON), the memory states diverge at the bit level. It’s not just "floating point noise" it’s a deterministic drift caused by FMA (Fused Multiply-Add) instruction differences. I wrote a script to inspect the raw bits of a sentence-transformers vector across my M3 Max and a Xeon instance. Semantic similarity was 0.9999, but the raw storage was different For a regulated AI agent (Finance/Healthcare), this is a nightmare. ...

New ask Hacker News story: Ask HN: Migrating old Substack posts to my own blog, have a question

Ask HN: Migrating old Substack posts to my own blog, have a question 2 by Praddy | 0 comments on Hacker News. I’m moving my older posts from Substack to my personal blog and I want Google to treat my blog as the primary source going forward. Constraints: - Substack doesn’t support canonical URLs (so I can’t point Substack → my blog). - I don’t want to use a custom domain on Substack. - Going forward, I want Substack only as the newsletter, and my blog as the SEO winner. I’ve seen the “ghost post” approach (replace most of the Substack post with a teaser + link), but I don’t want to delete/gut the original Substack content because I still want readers there to have the full post. Is there any way or a hack to get this donee??

New ask Hacker News story: Ask HN: Why isn't there competition to LinkedIn yet?

Ask HN: Why isn't there competition to LinkedIn yet? 7 by antfie | 3 comments on Hacker News. It seems there are many solutions for social media these days, but only one LinkedIn. Why are we still putting up with it? I’m surprised there’s not been a contender yet, or maybe I am not aware and perhaps that could be the rub; the challenge of acquiring enough traffic for the network effect to take hold.

New ask Hacker News story: Ask HN: What's the most open/hacker friendly Android phone for 2026?

Ask HN: What's the most open/hacker friendly Android phone for 2026? 4 by recvonline | 1 comments on Hacker News. I am a long time Apple user, but their software keeps getting buggier, worse and I just want to switch. I moved all my data to self hosting solutions, so I all I need now is an Android phone which… is fun? Like Framework Computer fun. Are there still community based OSes out which I can flash onto a phone? Last time I had an Android phone was 2013.
