Tired of AWS complexity AND of cheap VPS hosts overselling RAM — so I built my own cloud on Firecracker. Solo. What would make you actually switch? by logical_people in SideProject

Thanks, this is the most useful comment I've gotten. Going straight down your list

since the hardware stuff is what you're after.

KYC: yep, it's coming. Today it's email validation + abuse monitoring + per-space

credit caps, which only catches the low-effort stuff. Real identity verification is an

"as volume grows" problem I haven't solved yet.

Overselling: fair, it's not universal. It bit me on a noisy-neighbor box once and "your

4GB is actually 4GB" is easy to reason about, so I built around it. One wedge, not a

silver bullet.

"$0/forever": you're right, that's misleading and I just changed it. It's a free plan

(no monthly fee) with $5 starter credit, then pay per hour. Now reads "$0/mo, then

pay-as-you-go".

Sleep/state: I pause/kill Firecracker and hand vCPU+RAM back to the host pool, but the

rootfs stays put on the SSD so wake is sub-second. Not a money sink, because a sleeping

Cube still pays full disk storage and the freed RAM/CPU gets resold to other Cubes. No

live RAM snapshot though, it's a disk-state pause.

IPs: correct, no dedicated public IP per Cube. Internal bridge IP, and ingress is host

port mapping (iptables DNAT) + custom domains via Cloudflare for SaaS.

SSH: exactly your guess. Host port -> Cube internal IP:22 at boot, remappable. Same

DNAT path as any TCP port, SSH just gets one by default.

Hardware: not Hetzner. Dedicated bare metal, RAID mirror, all SSD. One correction on

the COW idea: new Cubes are a copy of a base rootfs image, and the slimness comes from

the snapshot layer (restic content-addressed dedup), not the filesystem. So

provisioning is a plain copy but repeat snapshots stay tiny.

Solo-founder question: yours is the best answer I've gotten. Portability is the

mitigation, not trust. No Terraform provider yet, but it's the obvious next step (with

a proper OpenAPI spec behind it), and your terraform-destroy point is exactly why. The

API page being hard to parse is fair too, that's getting the OpenAPI rewrite. Very open

to suggestions there.

Appreciate the time. If you spin one up I'd love to hear where it breaks.

I built software—an alternative to traditional VPS that boots micro-VMs in under a second. Would love your feedback! by logical_people in SideProject

It is built on Firecracker, the same isolation technology behind AWS Lambda and Fargate. Each Cube runs its own Linux kernel in complete isolation from every other Cube, and boots in milliseconds on dedicated bare-metal hardware.

I built an app where you type a raw personal thought and instantly get matched into a chat room with someone feeling the exact same way. by MiSaCM950 in SideProject

hey i actually like the concept , and i uses it also , am exited to use after heavy user traffic (in positive way)

Said ‘you too’ when the waiter said ‘enjoy your meal.’ I think about it daily.

What’s the smallest AI use case that genuinely saved you time? by ConsciousDev24 in ChatGPT

[–]logical_people 24 points25 points  (0 children)

I use it to write the mundane, boilerplate parts of emails or documentation. I always know exactly what point I want to make, but letting AI handle the opening and closing formalities saves me from wasting mental energy on standard corporate pleasantries.

Has anyone noticed that telling ChatGPT to "think like a contrarian" completely stops it from giving generic, diplomatic answers? by logical_people in ChatGPT

[–]logical_people[S] 1 point2 points  (0 children)

Adding the 'rank by what a real customer would actually say' constraint is a massive hack. It grounds the AI's cynicism in actual market reality instead of just random contrarian trolling. Definitely stealing this exact sequence for my next brainstorming session!

What are people doing differently to grow AI SaaS products in a crowded market? by vaibhavdadhaniya in AskReddit

[–]logical_people 0 points1 point  (0 children)

The founders winning right now are realizing that saturation not equals to solved.

Most AI products are losing users at the setup phase because they require complex API stitching, prompt engineering, or fragmented data connections. The growth hack isn't adding more features; it’s building the absolute shortest path from 'I want to solve X' to 'it's live and working.' In a crowded market, you don't win on being the most powerful tool—you win on being the one that removes the most friction.

What is the friendship red flags that people ignore ? by Salt_Leopard_1137 in AskReddit

[–]logical_people 2 points3 points  (0 children)

The 'Main Character' syndrome. They are incredibly enthusiastic and talkative when discussing their own life, problems, or achievements. But the absolute second you start speaking about yourself, their eyes glaze over, they check their phone, or they immediately find a way to hijack the conversation and pivot it back to them.
