The trick is to use the rem unit introduced in CSS3, which refers to the root element size. In mPDF, 1rem is equivalent to the font size of the HTML body element. All other elements which appear as blocks in the columns, such as headings, subheadings, and info boxes, need to have a vertical size which adds up to an exact multiple of the body text or its line-height. Using rem makes the calculation easier, and also means that changes to body text size will scale other elements proportionally.

The InterPlanetary File System (IPFS) is a peer-to-peer distributed file system that seeks to connect all computing devices with the same system of files. In some ways, IPFS is similar to the Web, but IPFS could be seen as a single BitTorrent swarm, exchanging objects within one Git repository. In other words, IPFS provides a high throughput content-addressed block storage model, with content-addressed hyperlinks. This forms a generalized Merkle DAG, a data structure upon which one can build versioned file systems, blockchains, and even a Permanent Web.

Is error reporting on and display errors on in development and off in production? Do not suppress errors in your code. Implement a logging framework. Use a caching strategy. Keep in mind and use programming design patterns and best practices. Use tests in your code and try to automate running these tests every time a change occurs in the code base. Review or at least audit team members’ code. Practice defensive programming. Learn and use OOP principles correctly. Have a solid workflow and processes for developing and deploying code. Differentiate between read / write database queries.

In this camera experiment, you can move and rotate your hand to change the visuals and your perspective. But what’s really amazing is what you can’t see – an invisible ball, pushing an invisible cloth, which in turn transforms a tunnel of colorful fractals in response to your hand movements.
