python - Can I use MD5 or SHA1 hashes for filenames? -


let's consider site users can upload files. can use md5 or sha1 hashes of contents filenames? if not, should use? avoid collisions.

you can use filename, minus reserved characters. particular choices tell nothing file itself, aside hash value. provided aren't uploading identical files, should prevent file naming collisions. if don't care that, have @ it.

usually people upload files in order pull them down. you'd need have descriptor of kind; otherwise users need open mass of files 1 want. perhaps better option let user select name (up character limit) , append datetime code. then, in order have collision, you'd need have 2 users select exact same name @ exact same time. include seconds in datetime code, , chances of collision approach (but never equal) zero.

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...
