Resources¶
Every tool we use in class and every source worth trusting for your project, in one place. All the tools run in the browser, are free and need no credit card: they work on the classroom's Ubuntu computers without installing anything.
Tools used in class¶
| Tool | What we use it for | Units | Account? |
|---|---|---|---|
| Google Classroom | Where you hand in every class activity and every deliverable. | All | Your school Google account |
| Google Docs and Google Sheets | The group's shared document (its version history shows who wrote what) and the spreadsheets for costs and data. | All | Your school Google account |
| diagrams.net | Drawing the automation pyramid, the IT–OT connections and the cloud architecture. Export as PNG and paste into your document. | UT1 · UT3 · UT6 |
No |
| GitHub Pages | Publishing your group's dossier as a static website. | UT3 |
Your own free GitHub account |
| AWS Pricing Calculator | Estimating what your company's systems would cost per month in Amazon Web Services. | UT3 |
No |
| Azure Pricing Calculator | The same estimate in Microsoft Azure, to compare providers. | UT3 |
No |
| Google Cloud Pricing Calculator | The same estimate in Google Cloud. | UT3 |
No |
| Teachable Machine | Training a small image or sound classifier in the browser: the AI demo of D4. | UT4 |
No |
| securityheaders.com | Checking which security headers a public website sends. Passive: it only reads what any visitor receives. | UT5 |
No |
| Mozilla HTTP Observatory | A second, more detailed passive check of a public website's security configuration. | UT5 |
No |
| Have I Been Pwned | Checking whether an email address appears in known data breaches. Try it only with your own address. | UT5 |
No |
Passive only
securityheaders.com and the Mozilla HTTP Observatory only read what the website already sends to any visitor, which is why we can use them on a real company. Never use any other tool to scan, probe ports or try logins on a company's systems. It can be a crime, and it scores 0.
Class datasets¶
Files hosted on this site. They are the exact copies we use in class, so your results will match the ones on the board. Open a CSV in Google Sheets with File → Import → Upload.

reserves-hotel-ficticies.csv |

Reliable sources for your research¶
Every fact about your company and its sector needs a source. These are the ones we use in class. All of them are free.
| Source | What you find there | Good for |
|---|---|---|
| Ibestat | The official statistics institute of the Balearic Islands: population, tourism, economy, companies, ICT use. | Numbers about the islands and your sector |
| Govern de les Illes Balears open data | The open-data catalogue of the Balearic Government: thousands of datasets on tourism, transport, environment, water, energy. | The D5 data-science pipeline |

| EUR-Lex | The official database of European Union law. | The RGPD, NIS2 and the AI Act, in full |
Where companies tell you about themselves
Before the statistics, read the company itself: its website ("about us", news, careers), its annual or sustainability report, its job offers (they reveal which systems it uses) and the local press. A job offer for "SAP consultant" is a source that the company uses SAP.
How to cite a source¶
One line per source
Write every source the same way, in the sources list at the end of the deliverable:
Author or organisation (year). Title of the page or document. Website or publisher. URL (consulted on DD/MM/YYYY).
Example: Spain (2023). Real Decreto 659/2023, de 18 de julio, por el que se desarrolla la ordenación del Sistema de Formación Profesional. BOE no. 174, 22/07/2023. https://www.boe.es/eli/es/rd/2023/07/18/659 (consulted on 26/10/2026).
In the text, point to it right after the fact: "Coinga was founded in 1966 (Coinga, s.d.)". Use s.d. when the page has no date.
A source is good when you can answer three questions: who says it (an official body, the company, a newspaper, a random blog?), when (is it still true?) and where you can check it again (a link that works). If you cannot answer all three, look for a better one, or label the claim as a hypothesis.
How sources, hypotheses and the rest of the project fit together is explained on The project.
