amazon web services - Manual acknolwedgement of sqs? -

currently using 'rabbitmq' reliable messaging delivery,we have plan move sqs.rmqp monitors consumers through tcp when consumer of queue goes down automatically re-queue messaging processing. will sqs monitor slaves? message visible in queue if 1 of consumer goes down while processing message? i have tried find out same documentation,i not find any. if 'slaves', mean sqs consumers, no, sqs not monitor consumers queue. in nutshell, sqs works this: a consumer requests message queue. sqs sends message consumer process , makes message temporarily invisible other consumers. when consumer finished processing message, sends 'deletemessage' requests sqs , sqs removes item queue. if consumer not send deletemessage enough (within configurable timeout period), sqs put message queue automatically. so sqs doesn't monitor consumers, if consumer requests messages - , nothing them - end in queue processed else. but if queue doesn't have c

Find the inverse of a Matrix in MATLAB, is inv(A) or A\eye(size(A)) more precise? -

this question has answer here: why matlab's inv slow , inaccurate? 3 answers the title explains already. if need find inverse of matrix, there reason should use a\eye(size(a)) instead of inv(a) ? , before ask: yes, need inverse, not calculations. ps: isequal(inv(a), a\eye(size(a))) ans = 0 so 1 more precise? update : question closed appeard duplicate of question " why inv in matlab slow , inaccurate ". question here differs not addressing speed, nor accuarcy of function inv difference of inv , .\eye calculate true inverse of matrix. if need inverse, should use inv . the inverse calculated via lu decomposition, whereas backslash operator mldivide calculates solution linear system using different methods depending on properties of matrix a (see https://scicomp.stackexchange.com/a/1004 ), can yield less accurate results inverse.

Create base Django model class for DB-view related models setting all ForeignKey-fields to on_delete=DO_NOTHING -
