The LINPACK benchmark report appeared first in 1979 as an appendix to the LINPACK user's manual. [4]LINPACK was designed to help users estimate the time required by their systems to solve a problem using the LINPACK package, by extrapolating the performance results obtained by 23 different computers solving a matrix problem of size 100.
Rewriting sections "pays off" in these circumstances because of a general "rule of thumb" known as the 90/10 law, which states that 90% of the time is spent in 10% of the code, and only 10% of the time in the remaining 90% of the code. So, putting intellectual effort into optimizing just a small part of the program can have a huge effect on the ...
Memory latency is the time (the latency) between initiating a request for a byte or word in memory until it is retrieved by a processor. If the data are not in the processor's cache, it takes longer to obtain them, as the processor will have to communicate with the external memory cells. Latency is therefore a fundamental measure of the speed ...
Like any computer-based test, adaptive tests may show results immediately after testing. [ citation needed ] Adaptive testing, depending on the item selection algorithm , may reduce exposure of some items because examinees typically receive different sets of items rather than the whole population being administered a single set.

The forgetting curve hypothesizes the decline of memory retention in time. This curve shows how information is lost over time when there is no attempt to retain it. [1] A related concept is the strength of memory that refers to the durability that memory traces in the brain. The stronger the memory, the longer period of time that a person is ...
Dr. Robert Newman, a longtime advocate for the use of methadone to treat heroin addiction, was quoted in the Times article as saying that buprenorphine “is associated with a large number of deaths.” Reached by HuffPost, he said the Times story was harmful to those in the recovery community. “I am not an expert in buprenorphine,” he said.
The myth might have been propagated simply by a truncation of the idea that some use a small percentage of their brains at any given time. [1] In the same article in Scientific American, John Henley, a neurologist at the Mayo Clinic in Rochester, Minnesota, states: "Evidence would show over a day you use 100 percent of the brain". [1]
