About NodeZero
NodeZero publishes short, data-driven articles on technology markets: AI, chips, devices, memory, storage and security. Every article starts from one question: what changed in price, and what changed in volume?
Why this site exists
Technology headlines often report one number, such as revenue growth or a price change, without the other half of the story. Revenue can rise while fewer units are sold. A product can get cheaper per unit while total spending on it soars. NodeZero puts the two side by side, so the numbers mean what they seem to mean.
Where the numbers come from
We use the most direct source available, in this order:
- Primary sources: company results and regulatory filings, government agencies and official alerts (for example the FBI, CISA or national statistics), and standards bodies.
- Industry research: market research firms and security researchers who publish their data and methods.
- Reporting: established news outlets, used for events and statements, and checked against the original source wherever one exists.
Every figure in an article links to its source. Each article ends with a "Notes on the data" section that explains definitions, gaps and anything we could not confirm.
How we check figures
- Each figure is checked against the source it cites, not copied from a summary of it.
- When sources disagree, we say so and give the range or the more conservative figure, rather than picking the most dramatic one.
- Our own calculations, such as revenue per unit or a share worked out from two counts, are labelled as ours, with the method explained.
- Figures we cannot confirm at a primary or reliable source are left out.
Evidence labels
Newer articles mark key figures with a small label saying what kind of evidence they are:
- Reported stated by a company or official body, for example in a filing or results release.
- Observed measured by a data provider in its own dataset.
- Surveyed answers given by survey respondents, with the sample size stated.
- Calculated by NodeZero our own arithmetic from the cited figures, with the method shown.
- Estimated a result that depends on assumptions, which the article explains.
How to read our charts
Colours mean the same thing across the site:
- Orange is price, or the risk side of a comparison.
- Blue is volume: units, capacity or count.
- Navy is revenue or total value.
- Grey is context or a reference point.
Charts are built from the published figures, not from images, so the numbers are in the page itself. Each chart names its source and has a "Copy link" button for sharing it directly.
Fairness
Articles describe what the data shows about markets, products and incidents. They do not blame individuals, and when a company is part of a story, its own statements are reported alongside the data. Security articles explain risks and protective steps, never how to carry out an attack. They apply the same idea as our market articles: how often something happens, compared with how much it costs or how many systems it reaches.
Corrections and updates
When new data changes a figure, or we find an error, the article is corrected and shows an "Updated" date at the top. Significant changes are described in the article's notes.
