How to PoC | Arbitrage with AI

do we really need betterpic and similar tool?

Or have they been superseeded by image 2 from openai?

Tl;DR

People still dont believe that a PoC can be built in 1h, not in 6 months.

How long will it take for this information to spread out?

Intro

Lets continue the business/entrepreneurial/BiP series of this year.

I hope you had time to Pressure-test your product brief since the last one.

Entrep CheckPoint

  1. Prepare a checklist: your brand should have one, including the unit economics and the value equation mindmap

  2. Dis-Qualify: specially if you have many ideas always after first 10

While building:

  1. SMART or it doesnt ship: a mantra, specially after building this on this section.

  2. Lean: Perceived value is the only value


Conclusions

A friend told me that in big corporations the narrative is that the ultimate proof for achievement is revealed at linkedin.

That having a website is like very cheap, as you can write anything and you have no way to check if whats written is true or not.

Not sure about you, but having as a hack for real value:

  1. The count of likes and hearts that an algorithm put in front of your face
  2. People re-inforcing pre-accepted ideas (herd behaviour, like whatever your boss posts)
  3. Telling how hard was your migration process to Canada and why you came back being another person

Doesnt seem quite… there, right?

Anyways, how can you proof value if you are not delivering any?

Luckily, some of us have proofs:

PS: you can make all the content of this blog as yours by just cloning :)

PS2: from next year, new curated posts might still be free, just not OSS, as Im preparing some changes around the consulting model.

Industries?

  1. Aerospace
  2. Mech Engineering
  3. FMCG/Logistics/Consumer Insights/Intelligence
  4. Crypto
  5. Marketing Analytics / RevOps
  6. Telecom/Big Data
  7. HealthCare Analytics
  8. AI and DevOps

Revops and GenBI is blooming!

Roadmap Check 2605

Its all about:

  1. https://agents.md/
  2. skills.sh, https://github.com/openai/skills
  3. Agents like: openclaw or the selfimproving ones like Hermes

Whats next?

Goals without values and w/o decomposed actions are useless

The last monthly review was this one

RoadMap26 Check | As of 0526 TBDDDD 📌

Coming from last year end review

  1. Weddings serverless + ads - WIP and last one here ⚙️

  2. To get back to mech simulations - not commercial ✅ - MBSD 2D With published ebook, the check on why I6 is the balance king and some math to blender video flow

  3. Prepare the DIY/DWY/DFY based on the ebooks and blog content ~ Wiki efforts - WIP ⚙️

  4. Books from D&A to web and concepts from kindle notes - Distillation WIP ⚙️

#npm run build && npx wrangler pages deploy dist --project-name jalcocertech-ebooks
  1. IoT end to end flow from sensor to dashboarding & langchain - WIP ⚙️

Put together an IoT 101 ebook!

Visible at http://192.168.1.2:8077/

  1. Custom Marketing analytics from custom high signal content creation to funnels Matplotlib, remotion/hyperframes stuff…

The ideas cemetery

  1. Scaling PRO Webs creation via PaaS - A better DIY website with free (programmatic) audit - Free web audits show problems here
  • https://diy.jalcocertech.com/
  • https://webaudit.jalcocertech.com/
  1. Real Estate Custom RAG and WebApp via DecapCMS | Cancelled and white-labelled
ℹ️
Personal monthly recap Where am I? here

Keep Doing

  1. Following my roadmap for this year, as planned here.

Yea, im not considering Side-Quests26 nor Tech talks.

Oh, also not the monthly selfhosted/homelab recaps.

  1. Monthly Life ~ IKIGAI Checks: just that not done in onenote, but in .md
#git clone /my-logseq-notes
  1. Quiiick PoCs: like the recent iperf3 speed monitoring related
git clone https://github.com/JAlcocerT/poc
cd ./poc/iperf

iPerf3 Ethernet local speeds

The recently upgraded trip planner from v3 to v4:

git clone https://github.com/JAlcocerT/Py_Trip_Planner
cd ./Py_Trip_Planner/poc-trip-planner-v4
#npm run dev
docker compose up -d --build
#docker ps | grep oc-trip-planner-v4-web-1

As i turned off Umami recently, I got it working at: http://192.168.1.2:3000

alt text

V3 used node+python, v4 is just node with even nicer charts with such tech stack

Or…the one around DHT temp/hum monitoring: I made a port to nodeJS to simplify the stack

git clone /RPi

With python+node you will need a more complex setup:

#docker ps | grep emqx
#cd ./RPi/Z_SelfHosting/pgsql
docker start timescaledb
#docker update --restart always timescaledb
docker inspect timescaledb --format '{{ .HostConfig.RestartPolicy.Name }}'

# docker run -d --name timescaledb \
#     -e POSTGRES_USER=pico \
#     -e POSTGRES_PASSWORD=pico \
#     -e POSTGRES_DB=sensors \
#     -p 5432:5432 \
#     timescale/timescaledb:latest-pg16

#tmux ls
#cd ./home/jalcocert/RPi/Z_MicroControllers/dht-webapp
cd ./home/jalcocert/RPi/Z_MicroControllers/RPiPicoW/picow-dht-webapp
tmux new-session -d -s mqtt "uv run mqtt_to_db.py"
tmux new-session -d -s webapp "uv run uvicorn main:app --host 0.0.0.0 --port 8077"

Run order:

  1. docker compose up -d in Z_SelfHosting/pgsql
  2. Create table + trigger once (psql block in readme)
  3. mqtt_to_db.py (systemd or tmux)
  4. uvicorn main:app –host 0.0.0.0 –port 8000

http://192.168.1.2:8077/

Than just one CLI and http://192.168.1.2:8078/

cd ./RPi/RPi/Z_MicroControllers/RPiPicoW/picow-dht-webapp-vpd-poc
docker compose up -d --build
#Web → http://<host>:8001 · DB → localhost:5433.
docker compose up -d #and here it goes timescaleDB + all the webApp

DHT22 x VPD x pgsql Webapp

With this upgraded tech stack and data lineage!

I got also some updates for finances with the aegis freedom poc and the stocks simple:

#git clone https://github.com/JAlcocerT/poc
cd ./poc/stocks-simple/web
npm run build
npm run start
#make help
ALLOWED_DEV_ORIGINS=192.168.1.18,raspberrypi.local npm run dev
  1. Generating random data animated videos & renders: is probably time to unify these…

Creating motion graphics data stories is fun:

Yea… its about time:

/eda-f1
/eda-geospatial
  1. Using GenAI to make real engineering recaps
git clone /mbsd
git clone /3Design
git clone /electronics-101
  1. Iterating
From Vibe Coding to Agentic Engineering | Setup early May📌
I need Landing Page based with a cool and modern UI.

Create also a makefile with the following commands:

* `make help` - Show available commands
* `make install` - Prepare the dependencies for local development
* `make dev` - Run development server

Create the `z-development-plan.md` with independent and testable phases that can be completed sequentially.

When it is completed, create a `z-walkthrough.md` with the steps to deploy the application and what each part of the tech stack does on a high level to bring the features to life.

The **full copy** of the landing, has to be goberned by a single `site.md` file.

Consider adding a Terms of Service / **terms and conditions and privacy policy** to the website, which will be governed by two separated markdown files.

Add also a faq section, that instead of been controlled via a json, lets have it controlled as per the frontmatter and content of separated markdown files inside the folder `faq`. 
Vibe Coding | Setup Jan26 📌

Go to whatever LLM you are using and ask: do you think that these requirements are clear enough?

Create a sth sth sth like... a Landing Page based on NextJS with a cool and modern UI

Include a `dockerfile` and `docker-compose.yml` that will control the title, description, open-graph image, favicon location and other global website variables via environment variables.

Add also a docker-compose.portainer.yml to use assuming that the image has been built already.

Create also a makefile with the following commands:

* `make help` - Show available commands
* `make install` - Prepare the dependencies for local development
* `make dev` - Run development server
* `make container` - Build and Run in Docker container

Create the `z-development-plan.md` with independent and testable phases that can be completed sequentially.

When it is completed, create a `z-walkthrough.md` with the steps to deploy the application and what each part of the tech stack does on a high level to bring the features to life.

Consider adding a Terms of Service / **terms and conditions and privacy policy** to the website, which will be governed by two separated markdown files.

Add also a faq section, that instead of been controlled via a json, lets have it controlled as per the frontmatter and content of separated markdown files inside the folder `faq`.

The logic should read them in order as per their file name and show them in the right component of the UI.

> When these change, consider sending an email to your existing clients!

Consider adding **Umami web analytics capabilities** to the WebApp when using the container, by adding the possibility to feed the PUBLIC_UMAMI_SCRIPT_URL and PUBLIC_UMAMI_WEBSITE_ID to be used via <script defer src="" data-website-id=""></script>

If you are using Python, design proper functions with docstrings, so that the codebase is understandable, scalable and self-documenting.

Then go to AntiGravity IDE and ask if the brd.md refined already with Gemini is clear enough.

If it is clear define the z-development-plan.md and proceed with the development phases.

As you will need to iterate across features, do it like a pro with change-requests / CRQ.

#sudo apt install gh
gh auth login
#gh repo create make-xyz --private --source=. --remote=origin --push
    
git init && git add . && git commit -m "Initial commit: simple landing website" && gh repo create make-xyz --private --source=. --remote=origin --push
###du -sh .
#docker stop $(docker ps -a -q) #stop all
#docker system df

#make help
#docker builder prune	
#sudo journalctl --vacuum-size=500M
sudo apt-get clean
sudo apt-get autoremove

Technical Stack and Design Requirements

To develop a modern, secure, and scalable web platform for hosting and streaming a single-user podcast.

The platform must offer a seamless, content-driven user interface and a flexible content management system supporting both web uploads and direct file system access.

The BRD, tech stack, clarifications, dev phases and walkthough. With sales and psyc plugged in!

Those Weddings B2B

Move past “product thinking” into “distribution thinking,” which is where most SaaS projects actually live or die.

A good use case for APIFY x lead enrichment and a phone: in case you doubt b2c vs b2b

/home/jalcocert/Desktop/leads-slubnechwile/venv/bin/python apify/json_to_csv.py && ls -lh leads.csv && head -n 5 leads.csv
#title;price;phone;categories;website

Open in Google Colab

Make sure to have the script prepared with objections handling and psyc in place.

Follows the “PAS” (Problem-Agitation-Solution) framework perfectly. Dont’t start with your product; start with their headache.

  • B2C covers the long tail (couples who search organically or click ads)
  • B2B covers high-LTV bulk deals through photographers
  • Email drip works on both (couple is in Firestore regardless of how they arrived)

alt text

Measure which channel has better LTV/CAC and weight accordingly

Stop Doing

  1. Collaborations with people around vague ideas/projects

those who dont have a clearer (>=) than what I expect before executing my own worthless ideas are to be skipped.

When you have certain volume, this is the kind of thing that you put into a disqualification form.

Have your own ideas checklist in place!

Start Doing

  1. As code is cheap and so are videos…

I need to think about the FOSS/JAlcocerTech yt videos rebump - TBC though

  1. Data is no longer a full thing, a data product is the upcoming new end to end

Because nobody will pay you to make a SQL group by and filters any more

As you know, agents are coming to the workspace, that includes pbi, looker and whatever

Why should you restrict yourself to existing dashboarding tools?

not talking about streamlit pocs, but full stack data pocs

The ideal reading order for a solopreneur:

  1. Cardone — get your sales energy and mindset right
  2. Cashvertising — learn the psychological triggers behind buying
  3. Ogilvy — elevate your craft and build a lasting brand

Together those three cover the full spectrum from hustle to strategy.
