About all we know is that some directions of change are more likely than others: we no more know *why* language changes than we know *why* the laws of physics are what they are. Both widening (_dog_ once meant 'mastiff') and narrowing (_deer_ once meant 'animal') are among the commonest forms of semantic change. In particular, in the 19C _arithmetic_ meant 'number theory', and so the part concerned with the computation of "ambition, distraction, uglification, and derision" (Lewis Carroll) was _elementary arithmetic_. (Before that it was _algorism_.) When _higher arithmetic_ got its own name, the _elementary_ part was dropped in accordance with Grice's Maxim of Quantity ("be as informative as you can, giving as much information as necessary, but no more"). This did not happen to _algebra_, which still can mean either elementary or abstract algebra, still less to _geometry_. In addition, from the teacher's viewpoint school mathematics is a continuum, including the elementary parts of arithmetic, algebra, geometry, trigonometry, and in recent times probability theory and statistics, for which there is no name other than _ mathematics_ when taken collectively. > In lower secondary school we would go to both Arithmetic AND also to > Maths classes. > What was taught in the latter?

She pays with a guinea; what is the smallest number of coins in change you can give her." (a guinea was 21shillings, 12 pence in a shilling, a crown was 5 shillings etc etc). I think I would be better called mental arithmetic. We had ounces and pounds, and stones and hundredweight. Inches, hands, feet, yards, chains, furlongs, miles etc. So perhaps arithmetic was a more required learning?

If recall correctly, the last time someone tried to submit patches, they overloaded some signal that was in use, and it was NACK'ed on that basis. I personally didn't care, because on my systems, I'll use GUI program like xload, or if I need something more detailed, GKrellM. (And GKreelM can be used to remotely monitor servers as well.) > > SIGLOST - Term File lock lost (unused) > > SIGSTKFLT - Term Stack fault on coprocessor (unused) > > If SIGLOST were used/needed it would seem like a very bad system design. It's used in Solaris to report that the client NFSv4 code could not recover a file lock on recovery. So that means one of the first places to look would be to see if Ganesha (an open-source NFSv4 user-space client) isn't using SIGLOST (or might have plans to use SIGLOST in the feature). For a remote / distributed file system, Brewer's Theorem applies --- Consistency, Availability, Partition tolerance --- chose any two, but you're not always going to be able to get all three.
