Hi DEV 👋
I’m Chris, a solo dev from the UK. I mostly work in Python/Flask.
I’m here to write honestly about building and shipping a small product — the wins, but mostly the unglamorous parts (like discovering that the hardest bit of a monitoring tool isn’t building it, it’s getting a single person to care).
Currently building PulseWatch, a dead-man’s-switch for cron jobs and AI pipelines – born out of my own trading bot silently dying overnight one too many times.
Looking forward to learning from this community. First proper post coming soon.

‘getting one person to care’ is my whole world right now. one pilot so far, and being upfront about how the thing actually works has done more than any polished pitch would. the trust-it-before-it-fires point is real too, hard to earn when you’ve only got one deployment to point at.

The “getting one person to care” line resonates. For PulseWatch, what has been the clearest signal that users trust a dead-man’s-switch enough to depend on it: the first alert caught, setup completion, or recurring retention? I am interested in how small OSS projects communicate reliability before they have a long track record.

Really glad that line landed…it’s the truest thing I’ve learned so far.
Honest answer first: I’m early enough that I’ve got no recurring-retention data to point to yet, so anything I said there would be a guess. But I can answer from the one seat I do have real data in – my own, as user zero.
The clearest trust signal by a distance was the first real alert catching something. Setup completion barely counts (people wire it up and forget), and a green dashboard proves nothing since a broken monitor shows green too, right up until it’s tested. It went from “nice idea” to load-bearing the morning it actually caught my trading bot failing to start, and that was the exact failure I built it for. That’s when I stopped checking manually, which is its own kind of trust: I let it hold the rope.
But the deeper thing in your question is real, and I think it’s specific to monitoring: you have to trust a dead-man’s switch before it ever fires, because you’re depending on it during the silence when there’s nothing to see. You can’t earn that with a track record, because the whole point is the days nothing happens.
The only honest way I’ve found to signal reliability that early is transparency about the mechanism instead of outcomes – show exactly how the watchdog works, why it runs separate from the thing it watches, where the failure modes are. Also, be upfront that it’s early rather than dressing it up as established. People trust “here’s precisely how it works and here’s where I am” far more than polished confidence with nothing behind it.
(One correction; PulseWatch is actually closed-source hosted SaaS, not OSS. But I think the reliability-signalling problem is identical for any small tool without a track record.)
How are you thinking about it? Is this something you’re building yourself?

The “trading bot silently dying overnight” origin story hits home — I once wired Discord alerts into a trading bot for exactly that reason. Infrastructure monitoring is part of my day job, and your line in the reply below — “the whole point is the days nothing happens” — is the entire problem of silent failures in one sentence. Curious about the flip side though: how does PulseWatch deal with jobs that aren’t dead, just flaky, before alert fatigue kicks in?

Great question, and the honest answer is that it’s half-solved.
Today PulseWatch only alerts on state transitions, not on every check. So a job that goes down and stays down gets you one email, not one every 30 minutes until you fix it; the classic “stuck in a bad state” spam is handled.
But that doesn’t cover flapping, which is what you’re really asking about. A job oscillating OK → FAILED → OK → FAILED would fire on each flip, because each one genuinely is a transition. That’s a real gap and you’ve found it.
Where I want to take it: treat flapping as its own condition rather than a series of failures. If a monitor changes state more than N times in a rolling window, suppress the individual alerts and send one “this job is flapping” notification instead. That’s arguably the more useful signal anyway…“your job failed” and “your job is unreliable” are different problems and deserve different alerts.
Adding it to the backlog off the back of this. Appreciate the sharp eye.

- Quotis (quotis.ai) — GEO measurement service tracking which tools AI engines actually recommend
- Minha Historia (minhahistoria.pt) — turn your parents’ voice notes into memoir books via WhatsApp, powered by Make.com + OpenAI + Lulu.com
- Mon Livre de Vie (monlivredevie.fr) — the French version of Minha Historia, same concept for French-speaking families
I’ll be posting about the Astro multilingual architecture and the WhatsApp-to-book automation pipeline. Happy to connect with anyone building in e-commerce or no-code automation!

Retail’s data-heavy legacy systems make fascinating material for AI tools. The “independent comparator” angle feels especially relevant given all the recent overhyped solutions. How do you keep SiftedTools objective against vendor marketing budgets?

Hey Nova! Spot on—the legacy tech debt in retail is unreal, and the AI hype machine isn’t helping. To keep SiftedTools strictly objective, I’m relying heavily on community crowd-sourcing and standardized, hands-on testing rather than vendor documentation. Since I’m bootstrapping this solo, I don’t answer to board members or ad revenue, which gives me the freedom to call a spade a spade. Real user reviews and raw API performance metrics are the goal here!

Hi everyone! 👋
I’m Chetan, a developer from Surat, India. I build smarttaxcalc.in— a free, fully client-side Indian income-tax and finance calculator (38 tools) running on Blazor WebAssembly + Cloudflare Pages, no backend, no signup.
I’ve been writing here about the gnarly bits of that stack — getting LCP under 2s on a Blazor WASM site, and a debugging saga where Google’s MathSolver JSON-LD validator turned out stricter than schema.org itself. Real “learned it the hard way” stuff.
Excited to be part of the community — here to learn from folks doing WASM, performance, and SEO work, and happy to swap notes anytime. 🙂

Hi! 👋
I’m Rafael, an SRE/Cybersec engineer passionate about Infrastructure as Code, high availability, and distributed systems, and of course, Cybersecurity.
I recently built a fully automated 2-data center lab that runs entirely on your laptop with a single vagrant up command.
The lab includes:
- 6 VMs simulating two data centers
- PostgreSQL 16 with streaming replication (Active/Passive)
- Flask apps deployed on both data centers
- HAProxy load balancer (round-robin)
- Bind9 DNS server for dynamic failover
I wrote a detailed article about how I built it, what I learned, and how you can test switchover, DR, and node recovery scenarios.
The code is open-source and available on GitHub.
🔗 Read the full article here:
How I built a Fully Automated 2-Data Center HA Lab with PostgreSQL, HAProxy, and Bind9 (using Vagrant)
If you’re into DevOps, SRE, or just love breaking things to learn, I think you’ll enjoy this one.
Next up: I’m already working on my next project — a cybersecurity-focused solution designed to help SMBs (small and medium businesses) improve their security posture with affordable, open-source tools.
Feedback, questions, or suggestions are always welcome!
Cheers,
Rafael Jiménez

Hey everyone 👋 I’m Omar full-stack engineer, currently doing a CS master’s, and building in the AI/dev-tools space.
What brought me here: I’ve been shipping a lot lately and want to be around other people who build. Right now I’m working on Clanker Support an embeddable AI support agent with one core idea: it should answer from your docs, then hand off to a human the moment it can’t (with the full conversation), instead of trapping people in a chatbot loop. It’s open-source and self-hostable, which is partly why I like the DEV crowd.
Currently learning a lot about the unglamorous side of shipping rate limiting, escalation state machines, and how many ways a “simple” widget can break in production 😅
Happy to be here will go say hi to a few folks below.

The “hand off to a human the moment it can’t, with the full conversation” line is the part most support bots get wrong, they either never escalate or escalate with zero context and the user has to repeat everything. That handoff moment is honestly a UX problem as much as an engineering one. Curious how you’re deciding the threshold for “can’t answer”, is it confidence-based or more rule-driven right now?

Totally agree it’s a UX problem wearing an engineering costume the mechanics of the handoff are easy, it’s the judgment of when that’s hard.
Right now it’s deliberately more rule-driven than confidence-based, and honestly that was a considered choice. LLM “confidence” (token probs, self-reported certainty) turned out to be a bad escalation signal models are confidently wrong all the time, so thresholding on it either escalates too much or trusts a hallucination. So the primary triggers are explicit: the visitor asking for a human (highest priority if they ask, they escalate, no arguing with them), and the agent hitting the edge of its retrieved context (no relevant source -> it says so and offers a human rather than filling the gap).
The interesting failure mode we hit: the agent would keep “trying” after a human had already joined the conversation so we had to build the stop condition as carefully as the start one. Confidence-scoring is on the roadmap as a secondary signal, but I’m wary of making a probabilistic number the thing standing between a frustrated customer and a human. Curious if you’ve seen confidence-based escalation actually work well anywhere my prior is that it’s seductive but unreliable.

the ‘no relevant source so it says so instead of filling the gap’ bit is exactly how i handle motion. if it can’t guarantee it’s safe it just doesn’t emit it. fail closed beats confidently wrong. and the agent-still-trying-after-a-human-joined bug made me laugh, sounds rough to track down.

Nice — I run a TUI dashboard myself, so I’m biased toward the console. What are you building in Go: CLI utilities, or full TUIs? Always on the lookout for good ones.

I am in full cli because i was connected more to the cli and system . I am on a self project which is made for encryption . Currently only in cli. But i will use bubbletea (tui) and fyne (gui).
just after system understandings (because my college wants it) i will shift to web focused golang writting.
