i write heavy heart, another programmer started project on computer. unbeknownst me had set git repo had never worked before, had never pushed or synced of data. i put in few weeks work on project, try crank out , assume being saved hard-drive. come , files reverted when received other programmer. call other programmer. other programmer informs me deleted repo start fresh on git hub. i'm guessing files never saved hard drive have been lost git hub delete? ideas || solutions || suggestions? your project stored locally deleting github repository doesn't affect it. use git log see if there commit can go to. if there 1 can use git checkout <commit> switch state. also can check if code on other branch. list branches use git branch switch git checkout <branch> you can try use git stash list , see if there dirty working directory can restore git stash apply <stash>

according matt woodward's blog, in the definitive guide couchdb authentication , security points out things couchdb i'm not sure understand completly. he says: "basically way security works in couchdb users stored in _users database (or elsewhere if like; can changed in config file)...". so, users of whole couchdb stored in single database, right? means if have more 1 application running in different databases within same couchdb i'd have handle users want access both application, correct? he says "database readers can read documents , views on specific database, , have no other permissions". then, adds "by default databases read/write enabled anonymous users, if define database admins on database". so anonymous users can or can't read documents in specific database? i'll start out saying articles, while still informative, several years old , possibly outdated. recommend reading through official docume

i have huge database tables filled scientific names, in parent-child relationship, this... taxon | parent mammalia | chordata carnivora | mammalia canidae | carnivora canis | canidae canis-lupus | canis i installed postgresql , started working on hierarchical query, it's far more complex thought. i'm thinking of sticking mysql , going original scheme, looks this: taxon | parent | family | order mammalia | chordata | (null) | (null) carnivora | mammalia | (null) | carnivora canidae | carnivora | canidae | carnivora canis | canidae | canidae | carnivora canis-lupus | canis | canidae | carnivora it looks amateurish, surprised discover catalogue of life apparently uses same scheme, more columns , on million rows. with scheme, can count children , grandchildren counting number of species match table.family > canidae, example. , can use series of "stairstep" queries figure out names of great grandparents, etc. so wondered benefits of hierarchical queries

can mybatis return hashmap of results, instead of list? e.g. given table: foo | bar 1 | 2 | b and query select foo, bar foobar return result of hashmap<string, string> map map.get(1) == 'a' , map.get(2) == 'b' etc? i've tried variations on following: <resultmap id="hashmapresult" type="java.util.hashmap"> <id column="foo" /> <result property="bar" column="bar"/> </resultmap> <select id="personstatuses" resultmap="hashmapresult"> select foo, bar foobar </select> but error: expected 1 result (or null) returned selectone(), found: ... where tables have primary keys, more useful able results map of pk => row, list of rows. you have pivot table, let column foo 's rows column, mybatis can not this, can use sql achieve this(here mysql solution): select max(case when foo
