Forgot to add... in a more complex program where this calculation is just a small-part you might use something like a Semaphore to signal between different threads. cheers -ben On Mon, 10 Dec 2018 at 06:10, Ben Coman <btc(a)openinworld.com> wrote: > This is running the calculation in a new Process (in general terms, our > "Process"es are "green-threads"). > You can't "return" values between threads.

This is running the calculation in a new Process (in general terms, our "Process"es are "green-threads"). You can't "return" values between threads. You need to pass it some other way through a variable. If you put that code into an instance method, then you could store the result in a class-variable. Change the Transcript to ```self inform: 'FInished' ``` and then have a different method you call after you see that to return the answer. cheers -ben On Mon, 10 Dec 2018 at 04:16, Roelof Wobben <r.wobben(a)home.nl> wrote: > Hello, > > I got this code from the discord channel > > secret := 'abcdef'. > zeros := '000'. > zerosSize := zeros size. > count := 0. > [ > [ candidate := secret , count printString. > ((MD5 hashMessage: candidate) hex first: zerosSize) = zeros > ] whileFalse: > [ (count \\ 10000) = 0 ifTrue: [ Transcript crShow: count ]. > count := count + 1. > ]. > Transcript crShow: 'ANSWER = ' , count printString. > ] forkAt: 35 named: 'Mining' > > but I like that there is no transcipt in the code > > so my question is how can I change this part( Transcript crShow: 'ANSWER = ' , count printString. > ) > > so it still returns the count. > > > I tried ^count printstring but that is not allowed > > > Regards, > > > Roelof > > > > Op 9-12-2018 om 12:29 schreef Roelof Wobben: > > Helllo, > > a question about day4 of 2015 > is it right that I can only solve this bruteforece > so begin at for example 1 , encode it, check for 5 zeros if found then I > have found it otherwise increase the counter and do it again > https://adventofcode.com/2015/day/4 > > Regards, > > Roelof > > >

This seems to work - at least loading seems to have gone thru but is it possible to shorten the following filename in the github repository itself cryptUIDlgSelectCertificateFromStore.winHandle.pwszTitle.pwszDisplayString.dwDontUseColumn.flags.reserved..st it is in https://github.com/pharo-contributions/Cryptography/tree/master/source/Cryp… i do not know if there any any other filenames that long EstebanLM wrote > Hi, > > Iâm sorry I didnât see this before. > This happens because there are many projects that are still using filetree > format which stores one file per method.
