java - Read file from sFtp server -

-

i'm reading file sftp server , load file database using spring batch framework below code m getting error

code: 

<bean id="cvsfileitemreadermeta" class="org.springframework.batch.item.file.flatfileitemreader">     <!-- read csv file -->      <property name="resource" value= "ftp://scmuser:scmuser%40123@172.18.228.32:22/home/scmuser/csv/meta.csv" />

error:

caused by: java.lang.illegalstateexception: input resource must exist (reader in 'strict' mode): url [ftp://username:password@hostname.com:22/home/scmuser/csv/meta.csv]

obviously resource not exist. either have ensure resource exists before attempting open or unset reader's strict mode using flatfileitemreader#setstrict , passing false

in strict mode reader throw exception on abstractitemcountingitemstreamitemreader.open(org.springframework.batch.item.executioncontext) if input resource not exist.

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

algorithm - Testing tetrahedron-triangle intersection -

-
i want determine whether given triangle intersects tetrahedron. not want compute solution polygon(if exists) itself. there library/package/published practical algorithm can used solve problem directly (unlike attempt below)? i think last resort have use standard polygon-polygon intersection algorithm implementations solve problem indirectly . my attempt on problem: thought of breaking problem of polygon-polygon intersection. each triangular face(say t1 ) of tetrahedron , given triangle t2 , thought of doing following: compute intersection(a line) between planes corresponding each triangle, l1 . for each triangle: for each edge of triangle l2 , compute point of intersection p between l1 , l2 . test(maybe using parametric form) of l2 , if point lies on edge l2 . if both triangles t1 , t2 , there exists at least one edge on intersection point p lies, implies triangles(and hence given tetrahedron , triangle t2 ) do intersect. create orthonormal fr
