Re:Apple increases MacBook and iPad prices by 20% on Thursday June 25, 2026 @01:00PM (#48676264)
I just checked this. I bought a secondhand 15" M4 Air last weekend and the trade-in value is still $630. So no, trade-in values didn't go up 20%.

Gymlocity (https://gymlocity.com) - All-in-one gym management platform for small gym owners.

Building this for personal trainers with home gyms and small 1-2 location owner-operated facilities. The big players (Mindbody, etc.) are overkill and expensive for this market.

Core features: class scheduling, member booking, Stripe payments, and workout programming (the part most gym software ignores - trainers still use spreadsheets or generic apps).

Stack: React 19 + Vite frontend, ASP.NET Core 10 API, PostgreSQL, multi-tenant architecture so each gym gets their own branded experience.

Currently polishing the member dashboard and workout tracking UI. The goal is something a solo trainer can set up in an afternoon without needing to call sales or sit through demos.

Re:How to Code Claude Code in 200 Lines of Code on Thursday January 08, 2026 @08:08PM (#46548871)
I’ve had decent results with this for context management in large code bases so far https://github.com/GMaN1911/claude-cognitive
Solid platform - clean and useful for algorithm practice.

Quick suggestions:

  - GitHub OAuth would feel natural for devs.
  - Broaden language support (C#, TypeScript, Ruby).
  - Add dark/light mode toggle for comfort.
Excited to see where it goes — thanks for building.
Re:250MWh 'Sand Battery' to start construction in Finland on Thursday November 27, 2025 @10:30PM (#46075255)
In a cold climate, I would expect burying it to use the ground as a natural insulator. Why was an above ground design chosen?

Specifically, does the need for heavy insulation and the active heating of the sand make the ground a less effective or even problematic insulator? Could excavating and building a below-ground foundation for a high-temperature device like this be more complex and expensive than an above-ground silo? How would permafrost conditions affect this design?

It seems that this is directional, flowing from Android to Apple but not necessarily back (e.g., me airdropping a photo to my parent who uses Android). I'd love for this to work in the other direction as well.
Re:Ask HN: What are you working on? (September 2025) on Tuesday September 30, 2025 @09:17AM (#45425037)
I’m building https://www.kidcarekit.com, a Rails SaaS for family-run daycare centers that still juggle spreadsheets and phone calls. It wraps waitlist management, enrollments, and Stripe billing into a single dashboard with Tailwind + Hotwire on the front, Devise for auth, and Azure Blob for logos. Solid Queue handles scheduled jobs like weekly tuition and late fee automation so owners get predictable cash flow without hand-cranking invoices, while MailerSend keeps parents in the loop.

Right now I’m polishing the onboarding flow so new centers can import families, configure their billing cadence, and connect Stripe in under ten minutes. Next up is richer analytics (occupancy tracking and revenue health) and rolling out a guided setup for late fee policies. If you’re running childcare ops or know someone who is, I’d love feedback on the workflow pain points you still feel daily.

Ask HN: What's your secret weapon for keeping code/docs/tests from rotting?

I've been using cursor lately to handle some (most) of the grunt work and it's been surprisingly useful for two things: keeping documentation from going stale and spotting gaps in test coverage. For example, I'll ask it things like "what's the most likely way this function could break?" and it will suggest edge cases I hadn't thought of.That said, it's not (maybe?) magic and sometimes...

I've been grinding on kidcarekit.com for a long while in fits in spurts. I find myself working more on the DevOps side rather than the actual functionality but I've learned so much about rails and DevOps that it's been a net win for me even though it doesn't functionally do much yet!

Thanks for that! It seems that unsloth actually beat me to [it](https://huggingface.co/unsloth/DeepSeek-R1-Distill-Llama-8B-...)!

Edit: Running the DeepSeek-R1-Distill-Llama-8B-Q8_0 gives me about 3t/s and destroys my system performance on the base m4 mini. Trying the Q4_K_M model next.

Re:DeepSeek-R1 on Monday January 20, 2025 @09:44AM (#42769224)
I wonder if (when) there will be a GGUF model available for this 8B model. I want to try it out locally in Jan on my base m4 Mac mini. I currently run Llama 3 8B Instruct Q4 at around 20t/s and it sounds like this would be a huge improvement in output quality.

Re:Show HN: Poll Ponder vote regret analysis on Wednesday November 13, 2024 @03:10PM (#42129430)
I initiated this experiment to assess the feasibility of rapidly transitioning from a Rails 8 application to a Kamal-powered Linode virtual machine. My initial hypothesis that individuals experience regret after voting has been disproven based on the relatively low response rates (0% regret expressed). It is uncertain whether this project should be continued, but I would welcome any feedback.
I found that airplane mode solved my oasis battery issues!
For Spectrum to find the broadband facts you have to go through the order process and then a "Show Broadband Label" will show up on the internet package selection. Buried pretty deep.

Edit: There is also a little bit of a dark pattern. The price shows 49.99/mo for 12 mos with auto pay, but the Broadband Facts sheet shows price at $84.99 and says "This monthly price is not an introductory rate". Very shady from my (only) option for ISP.

Disappointing (but understandable) that this is not available for my 14 Pro Max.
That’s really interesting, amused that it’s still going on today. Thanks!
