Free downloadable guides, cheat sheets and ebooks on Linux, the command line and open-source software from the It's FOSS team.
Why I recommend it: Good beginner-friendly Linux material — the cheat sheets are worth keeping open while you practise.
A one-page cheat sheet covering the five rules of effective communication, the three types of conversation (informational, emotional, social) and twenty persuasive phrases you can use in real conversations.
Why I recommend it: Print it and keep it beside you for a week of meetings and interviews. The twenty phrases are the part people actually use.
A three-page printable reference for Google Gemini: the PART prompt formula (Persona, Action, Reference, Tone), follow-up prompting, when to use Flash, Pro and Thinking models, saving your own context in settings, and worked sample prompts for Gemini inside Chrome, Gmail, Docs, Sheets, Slides and Drive. Includes a plain warning about Gemini being confidently wrong.
Why I recommend it: Print this and keep it next to you for a week. Most people get weak AI output because they skip the persona and the reference, and this one page fixes that faster than any course will. The limitations box at the bottom is the part to take seriously.
