Every hall on the island
27 of them, 15 the right way up and 12 upside down. The city above is this list in three dimensions — the same doors, drawn instead of written.
The Right Side Up
- Audio Turning a recording into text on your own machine, subtitles that fit the platform, and the consent problem in cloning a voice.
- Business Software for one person or a very small team: writing an invoice, getting paid, how long to keep records, and the rules on emailing customers.
- Chat What an AI chatbot does with what you type, quoted from the published policies with dates — plus who owns ChatGPT and what deleting really removes.
- Code Coding assistants and what they cost you in checking: what the tool sees of your project, whose terms apply to the output, and what runs but is wrong.
- Detect A guide for AI detectors, for humanisers, for plagiarism checkers and for grammar tools — and what the scores they produce actually mean.
- Docs One guide for every PDF job, for Office files, for invoices and for signatures, and which of them need nothing installed at all.
- Images Resizing, removing backgrounds, converting formats and AI generation, one guide each — with the route that needs nothing installed given first.
- iPhone What each iPhone setting actually does, where Apple moved it, and the switches that turn out to control something other than their name.
- Making an invoice Before choosing an invoice generator, know what has to appear on the document. The published list, the free ways to produce one, and what VAT changes.
- Screens Computer screen problems, sorted: how to tell a damaged panel from the machine behind it, and when the repair costs more than the laptop is worth.
- Software Installing things safely, recovering lost files, a machine that has become slow, and the settings Windows and macOS moved somewhere new.
- Study A guide for each citation style, the reference list that has to match one exactly, and the note systems that hold the rest of the work together.
- Video The export problems that cause most of the trouble — size, format, subtitles — and recording a screen without paying for anything.
- Web Making a site mobile friendly, moving a domain, the certificate behind the padlock, and the two errors that stop a site loading.
- Work How to write a resume when the first reader is software: the document, the systems that parse it, cover letters, and the interview that follows.
The Upside Down
- Anonymity What a private browser blocks by default, what incognito mode never did, and where encrypted DNS changes who can see where you go.
- Breach What to do when a company says your details have leaked: the order that matters, the password to close first, and why being in a breach is normal.
- Dark web What the dark web actually is, and what it is not: the deep web is a different thing, and most of what people believe about both came from television.
- Devices Encrypted phones and private messaging: the difference between a service that cannot read your messages and one that has merely promised not to.
- Footprint Taking down what is public about you: the data brokers, the right to be forgotten, and the old accounts that are worth closing before anything else.
- Identity When somebody starts using your details: the order of operations, the deadlines attached to money, and the account to close before you touch the bank.
- Malware How to remove malware, device by device: the emergency sequence, what each security program says it does, and the questions people ask while panicking.
- Password One guide for each password manager, the second factor and its weakest form, and the questions people ask themselves at midnight.
- Scams Phishing email and scam calls: what to check before acting, whether to ring an unknown number back, and why a familiar number on screen proves nothing.
- Temp mail Throwaway addresses and permanent aliases: what each is for, why one is catastrophic on an account you may need back, and how plus addressing works.
- Tor What Tor Browser is for, when a VPN is the wrong tool entirely, and the habits that matter more than any of the software involved.
- VPN What a VPN tunnel changes and what it does not, the kill switch that proves it, and why nothing here is ranked until we have paid for it.
