The heptahydrate can be prepared by neutralizing sulfuric acid with magnesium carbonate or oxide, but it is usually obtained directly from natural sources. It is on the WHO Model List of Essential Medicines, the most important medications needed in a basic health system.

Worse is better Rise of Worse is Better", Gabriel claimed that "Worse-is-Better" is a model of software design and implementation which has the following characteristics (in approximately descending order of importance): Gabriel argued that early Unix and C, developed by Bell Labs, are examples of this design approach. Gabriel contrasted his philosophy with what he called the "MIT/Stanford style of design" or "MIT approach" (also known as "the Right Thing"), which he described as follows. Contrasts are in bold: Gabriel argued that "Worse is better" produced more "successful" software than the MIT approach: As long as the initial program is basically good, it
