Magnesium sulfate sanderite are rare. Kieserite is a monohydrate and is common among evaporitic deposits. Anhydrous magnesium sulfate was reported from some burning coal dumps. Double salts containing magnesium sulfate exist, for example there are several known sodium magnesium sulfates and potassium magnesium sulfates. An abnormally elevated plasma concentration of magnesium is called hypermagnesemia. Magnesium sulfate Magnesium sulfate is an inorganic salt with the formula MgSO(HO) where 0≤x≤7. It is often encountered as the heptahydrate sulfate mineral epsomite (MgSO·7HO), commonly called Epsom salt. The overall global annual usage in the mid-1970s of the monohydrate was 2.3 million tons, of which the majority
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
