Maurice Noualhier

Martial Jean Maurice Noualhier (1 September 1860, La Borie, Haute-Vienne – 7 April 1898, Arcachon[1]) was a French entomologist who specialised in Hemiptera.

He was the son of Martial Noualhier and Anaïs née Pougeard du Limbert. Maurice Noualhier made collecting expeditions to Switzerland, to Morocco and to Algeria. He moved to the Canary Islands for his health and named a number of new species there. He purchased the Hemiptera and Coleoptera collection of Lucien François Lethierry (1830–1894).[2] These specimens along with his own were left to the Muséum national d'histoire naturelle and his library to the Société entomologique de France of which he was a member.[1]

Species

Noualhier named over fifty species in his short life, at least twenty-nine of which continue to be valid, including:[3]

  • Acrorrhinium conspersum (Noualhier, 1895)[4]
  • Anisops debilis canariensis (Noualhier, 1893) (aquatic backswimmer bug)[5]
  • Cixius verticalis (Noualhier, 1897)
  • Cosmoscarta septempunctata (Noualhier & Martin, 1904)
  • Cosmoscarta dimidiata (Noualhier, 1896)
  • Cyphopterum fauveli (Noualhier, 1897)
  • Eudolycoris alluaudi (Noualhier, 1893)
  • Hemisphaerius interclusus (Noualhier, 1896)
  • Laternaria monetaria (Noualhier, 1896)
  • Oecleus cucullatus (Noualhier, 1896)
  • Oecleopsis petasatus (Noualhier, 1896)
  • Ploiaria putoni (Noualhier, 1895)
  • Ricanoides flabellum (Noualhier, 1896)
  • Stusakia picticornis (Noualhier, 1898)[6]
gollark: Or Great Information Transfer.
gollark: Git stands for GIT Is Tremendous.
gollark: The stages of git clone are: Receive a "pack" file of all the objects in the repo database Create an index file for the received pack Check out the head revision (for a non-bare repo, obviously)"Resolving deltas" is the message shown for the second stage, indexing the pack file ("git index-pack").Pack files do not have the actual object IDs in them, only the object content. So to determine what the object IDs are, git has to do a decompress+SHA1 of each object in the pack to produce the object ID, which is then written into the index file.An object in a pack file may be stored as a delta i.e. a sequence of changes to make to some other object. In this case, git needs to retrieve the base object, apply the commands and SHA1 the result. The base object itself might have to be derived by applying a sequence of delta commands. (Even though in the case of a clone, the base object will have been encountered already, there is a limit to how many manufactured objects are cached in memory).In summary, the "resolving deltas" stage involves decompressing and checksumming the entire repo database, which not surprisingly takes quite a long time. Presumably decompressing and calculating SHA1s actually takes more time than applying the delta commands.In the case of a subsequent fetch, the received pack file may contain references (as delta object bases) to other objects that the receiving git is expected to already have. In this case, the receiving git actually rewrites the received pack file to include any such referenced objects, so that any stored pack file is self-sufficient. This might be where the message "resolving deltas" originated.
gollark: UPDATE: this is wrong.
gollark: > Git uses delta encoding to store some of the objects in packfiles. However, you don't want to have to play back every single change ever on a given file in order to get the current version, so Git also has occasional snapshots of the file contents stored as well. "Resolving deltas" is the step that deals with making sure all of that stays consistent.
