DSI History

Data Securities International was founded in 1982.[2] The company grew steadily over the years before being sold to Iron Mountain in 1997.[3]

Data Securities International introduced the concept in the mid 1980s for a Total Software Value (TSV) that uses the composites of Ownership Value (OV) or the software inventory, Market Value (MV), and Internal Cost Savings (ICS) as values and influencing variables of software as a financial asset. A TSV software inventory valuation (OV) analysis looks at the sum total (or bundle) of the various software components or intellectual assets that make software usable as a product.[4]

Total Software Value is explained in the book "The Long Journey to Software Valuation" see ISBN 978-1-7344129-0-1 and Copyright Registration: TXu 2-181-571 [5]

gollark: Of course.
gollark: I'm not entirely sure how, but it seems to construct a tree/maybe deterministic finite automaton/finite state machine/I don't know theoretical CS which matches anagrams and unmatches unanagrams.
gollark: ```pythonimport collectionsdef do_thing(s): if len(s) == 1: return { s[0]: True } out = {} for i, c in enumerate(s): without = s[:i] + s[i + 1:] things = do_thing(without) out[c] = things return outdef match(r, s): print(r) c = r for i, x in enumerate(s): print(x) try: c = c[x] if c == True: if i + 1 == len(s): return True # full match else: return False # characters remain except KeyError: return False # no match return False # incomplete matchentry = lambda a, b: match(do_thing(a.lower().replace(" ", "")), b.lower().replace(" ", ""))```Here is my entry (pending a port to osmarkslisp™️). This is definitely my entry.
