The Categories Worth Knowing

Section 01Your browser is more than a window

The browser is the program you live in. It fetches pages, runs web apps, stores passwords and keeps a detailed record of where you go — which means picking one thoughtfully is worth the effort. For most people on most days, the question is not really which browser is fastest (they are close) but what data the browser collects, what it shares with its maker, and how easy it is to harden its defaults. Look for one that respects your DNS settings, doesn't phone home with your browsing history and handles extensions without demanding an account.

Office software covers word processors, spreadsheets and presentation tools — the category most people already have from a workplace and often don't think twice about. The interesting question here is file format: a program that saves only in a proprietary format creates a quiet lock-in. Open formats like ODF (used by LibreOffice) mean you can move your documents between programs freely, share them without worrying whether the recipient has the same software, and read them years later. LibreOffice, developed under the stewardship of an independent foundation, is the best-tested example of what open-source office software looks like at maturity.

Section 02Media and creative tools: where depth varies most

Media players solve a specific and underappreciated problem: different video and audio files use different codecs, and a player that only handles a handful will fail on files you've had for years. VLC has earned its reputation precisely because it bundles the codecs rather than making you hunt for them, and its open-source licence means you can inspect what it actually does with your files. When evaluating any media player, check the codec list before you need it.

Image editors, audio tools and 3D software vary more in depth than in category.

Image editors, audio tools and 3D software vary more in depth than in category. GIMP handles photo retouching and image manipulation; Audacity handles recording, editing and cleaning up audio; Blender handles 3D modelling, rendering and animation with a scope that surprises people who encounter it for the first time. These programs share a common trait worth knowing about: they tend to have steeper learning curves than commercial equivalents, not because they're worse but because they don't hide their power behind simplified interfaces. The investment pays off if the task is recurring; for a one-off job, simpler tools exist.

Section 03Security tools earn a different kind of scrutiny

Password managers and encryption tools belong to a category where the open-source principle changes the stakes. A password manager that won't show you its source code is asking you to trust its security on faith alone. KeePassXC, for example, stores your vault locally in an open format, and its code has been reviewed by independent auditors — that review history matters more than any marketing claim. When assessing security software, look for an independently audited codebase, active maintenance and a clear explanation of what the program does with your data.

Secure messaging operates on similar logic. End-to-end encryption is a technical claim, and the only way to verify it is to read the protocol specification and the implementation — or rely on others who have. Signal's protocol is published and has been widely reviewed; that public scrutiny is the actual source of confidence, not the app's reputation alone.

Section 04Compression and archiving: the unglamorous workhorses

File archivers — 7-Zip being the most commonly cited open-source example — sit at the bottom of most people's mental software map but do a job nothing else covers as cleanly. The things to check are modest: format support (ZIP, 7z, TAR and RAR cover most real-world cases), whether the tool is still actively maintained, and whether it came from its official project page rather than a repackaging site that may have added extras you didn't ask for.

Across all these categories, the same questions apply: where does it come from, who maintains it, what does it do with your data, and can anyone verify that? The category shapes what matters most, but the underlying questions stay the same.
