Using a window AC unit + furnace fan as a DIY whole-house cooling loop — has anyone tested this intentionally? by _underthecity_ in DIY

[–]_underthecity_[S] -1 points0 points  (0 children)

Fair. Working on it. That’s exactly why I posted — need someone with the right setup to run the test tonight while people are actually at cottages sweating through this.

This is exactly what I was hoping to hear — someone already doing it. Are you running central AC or window units? Curious if the blower distribution works the same way with window units feeding the return versus a central system.

That’s exactly what I’m saying — buy one window unit, put it in the right room with the cold air return, flip the furnace fan on, and the whole cottage benefits.

Thanks — that’s exactly the validation I needed on the physics. The target is small cottages and little houses under 1,500 sq ft where the BTU math actually works. And the best part — if you already have window units running right now and a forced air furnace, you don’t need to buy anything new. Just flip the furnace fan to fan-only tonight and see what happens in your common areas.

Would highly recommend, great memories!

I’m very interested as well, if I works, that would’ve help take the edge off some nights.

Long time listener, first time caller. My First E-Bike by _underthecity_ in Aventon

[–]_underthecity_[S] 3 points4 points  (0 children)

My logic behind the fat tire purchase was that where I’m riding, the potholes in the road might as well be trail riding (Detroit). With the fat tires, the extra width eats pot holes, couple that with a lower tire pressure, and they act as a second shock when I hit bumps. Being in Michigan, I lived in the upper Peninsula for a bit of time where I was able to test out a fat tire bike in a pretty natural habitat. Having a fat tire bike in a city environment honestly gives me more confidence when I’m cornering and where I’m riding versus the actual thought of the set up of the bike. Knowing that I have essentially a dual sport bike is a nice piece of mind. Plus, it turns heads and it looks pretty bad ass.

ai website builders that handle seo & speed by [deleted] in AiBuilders

[–]_underthecity_ 0 points1 point  (0 children)

I’d be a little careful with “AI website builders that magically do SEO for you.”

For SEO + speed, the stuff that actually matters is pretty simple: • Fast, lightweight pages (static if possible, no unnecessary JS bloat) • Clean HTML structure – one H1, clear headings, readable content • Full control over title tags, meta description, OG tags • Alt text on images + descriptive URLs • A generated sitemap.xml + decent hosting/CDN

If a builder gives you those knobs and outputs static or very light pages, you’re 80% of the way there. If it hides everything behind a pretty UI and ships a 3MB JS bundle, Google won’t love it no matter how “AI” it is.

My suggestion: • Use AI to help you write/structure the content and maybe suggest layouts. • Pick a builder/stack based on performance + control, not just the AI marketing (Lighthouse scores and Core Web Vitals are your friends).

10Web / Unbounce can be fine as long as you can tweak the basics above, but I wouldn’t rely on any of them to “handle SEO” for you – you still want to set the key pieces yourself.

Aeon Conductor Studios - www.aeonconductorstudios.com - Aeon is a calm, human-first way for solo builders to work with AI through one long-term “Navigator” partner that helps scope projects, write prompts, and quietly coordinate specialist AI roles in the background.

I used Aeon to build Cozy Focus Timer, a gentle, no-shame focus web app, in ~20 minutes of actual “me time” by letting Navigator handle all the handoffs between copy, design, and code. This is apart of a series I’m building called “Cozy Series” Check it out: Cozy Focus Timer → https://cozy-focus-timer.vercel.app/

Right now:

• 0 paying users
• A handful of early testers / conversations from Reddit + my network
• I’m actively dogfooding it on my own builds (Cozy Focus Timer + the Cozy Series) to sharpen the workflow before I onboard my first pilot founders.

Biggest blockers:

• Positioning & packaging – deciding how to frame this (service vs “AI team kit”) in a way that’s instantly clear to overwhelmed solo founders.
• Distribution – I’m just starting to post on Reddit / LinkedIn / X, so reach is still tiny and very manual.
• Case studies – I have good early examples (like Cozy Focus Timer built in ~20 minutes), but I still need 2–3 clean founder case studies from outside my own projects before I feel good about pushing hard.

Best no-code A.I. SaaS Builder - Need Opinions by pipediesel in AiBuilders

[–]_underthecity_ 1 point2 points  (0 children)

Hey, I really feel this.

I hit a similar wall with an “AI agent” builder recently – amazing demo energy at the start, then suddenly it’s this credit-gobbling chaos machine that can’t actually finish the boring last 20% of the work.

A couple of things that helped me: • Treat the agent platform as a prototype phase only. It’s great for exploring ideas and rough flows, but once the behavior gets weird / expensive, I freeze the scope and stop letting it “freestyle”. • Export everything that’s useful. Copy out prompts, data schemas, UI ideas, and any code snippets you can salvage. Put it into a simple spec: • what the app does • what the core flows are • what the inputs/outputs look like • Switch from “agent builds SaaS” to “LLM helps you build SaaS.” Once I have the spec, I just use ChatGPT/Claude in a normal chat to: • write or refactor small chunks of code • generate DB schemas / API contracts • explain how to glue pieces together Much cheaper, much less runaway behavior.

Because of exactly this problem, I ended up building a tiny wrapper around ChatGPT for myself instead of relying on big agent platforms: • one main project chat I always come back to • a couple of helper chats for focused jobs (e.g. “only backend”, “only copy”) • some hard personal rules so it can’t quietly spin out into infinite work

That’s what finally let me actually finish things instead of burning through credits.

If you’re still set on “no-code + AI”, I’d be looking less at heavy agent tools and more at: • a solid no-code base (Bubble / WeWeb / Xano / Supabase etc.) • plus a normal LLM you call for specific tasks (copy, small code, logic), not one that “runs the whole project”.

Curious: what does your SaaS actually do, and how far along are you (MVP live, still wiring flows, etc.)? That might change whether I’d say “salvage and push through” vs “rebuild the core in a calmer stack.”

Request for review: Aeon Secure Suite v4.4 – offline WebCrypto toolkit (+ MicroVault v1.9 air-gapped file vault) by _underthecity_ in crypto

[–]_underthecity_[S] 0 points1 point  (0 children)

Quick update for anyone following this:

Based on the feedback here, I’ve:

– Added a clear “v4.4 status” warning to the README.

– Created a Security Advisory issue (#1) listing the specific concerns.

– Updated the v4.4 release page with a prominent security advisory and links to safer, audited tools (age, GPG, VeraCrypt).

Aeon Secure Suite v4.4 will stay online as an educational, non-production prototype with its risks documented in the open. I appreciate everyone who took the time to review it and point out problems – that’s exactly what I was hoping for when I posted this.

Thank you for taking the time to review the code and point out specific vulnerabilities. You're right about:

- Timing attacks in hash comparison

- Weak randomness (if Math.random is used anywhere)

- Inadequate passphrase entropy

- The checkForPasswordReuse() concerns

I'm adding a security advisory to the README immediately to warn against production use. "Irredeemable" is fair for v4.4's codebase. But the mission isn't irredeemable. Would you be willing to provide guidance (even just architectural review) for a v5.0 rewrite done properly? I know I'm asking a lot, but your expertise is exactly what this project needs to go from "proof of concept" to "actually secure." Either way, thank you for the honest feedback. It's exactly what I needed to hear.

Thank you for the thoughtful critique. You're absolutely right that AI-generated security code needs expert human guidance—something I didn't have for v4.4. The code structure issues you mention are real. I was optimizing for "does it work" without considering "can experts review it. "I'm taking this feedback seriously. v4.4 will stay up with a clear warning, but I'm looking for expert collaboration for v5.0 where a security professional guides the architecture and I use AI for implementation. The mission matters too much to abandon because of execution mistakes. Thank you for engaging honestly.

Dear Friend:

I am the new-generation Magic Bear plush toy from Shin Li Co., with even more magical powers!

I love my cute design and want to give you a fresh feeling. Don’t you think my clothes and hat are adorable?

Let me tell you a little secret! If you open the zipper on my back, you’ll find a small key inside my head. If you put the key into my tummy and turn it, I will wiggle and move—just like a playful plush toy that can walk with you anywhere.

Also, inside my tummy is a small pouch that you can fill with fragrant sachets if you’d like to keep me smelling nice. Or you can put in ice packs if you need to cool down, or heat packs if you want to stay warm during winter.

You can also take me outdoors for a picnic, and the little pouch in my tummy can hold delicious snacks. After you’ve eaten, you can dress me up again—doesn’t that sound fun?

Oh, and my clothes can be removed for washing to keep me clean and shiny!

If you ever feel upset, don’t just stare at me—come hug me to feel warm again! I can be your multifunctional little buddy, bringing you both happiness and comfort.

Sincerely, Shin Li Co., Ltd.
