in bash script have variable fete wich contains

{"feastedsaint": "eline,helena,helene,heliena,laetitia,lena,lenaic,nelly"}

and in variable text

eline,helena,helene,heliena,laetitia,lena,lenaic,nelly

how can linux / bash commands?

using 

var='{"feastedsaint": "eline,helena,helene,heliena,laetitia,lena,lenaic,nelly"}' names=$(jq -r .feastedsaint <<<"$var") echo "$names" 
eline,helena,helene,heliena,laetitia,lena,lenaic,nelly

the jshon equivalent be

names=$(jshon -e feastedsaint -u <<<"$var")

Is there a better way to structure post methods in Class Based Views -

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
