Re: [Pharo-project] Can't load OSProcess in last Pharo Core 1.3

by David T. Lewis

This is fixed in both OSProcess and CommandShell on SqueakSource. I found an old comment in my code that says this: "Some images may have a bug in startup list processing. Add this class to a known place in the middle of the list to avoid getting bitten by the bug." So I knew that it was safe now to just use #addToStartUpList: instead of #addToStartUpList:after: This is the reason that people like me with bad memories need to write good comments ;-) Dave On Fri, May 20, 2011 at 03:18:53PM -0400, David T.

Re: [Pharo-project] SIXX problem for ScaledDecimal

I did run into this previously and it bugged me enough that I created FixedDecimal (at http://www.squeaksource.com/FixedDecimal.html ). It does not keep an internal more precise number - it keeps exactly what it shows you. (Although the implementation is somewhat odd - it does do what it is supposed to do.) -Chris

Can you inspect the RPackageOrganizer to see if it comes from RPackage or from Nautilus please ?

Let's assume something like that: #/bin/bash if [ $# -lt 2 ] then echo $0 "Wrong number of parameters. Plz, specify rant/bragging" else /usr/local/bin/restartOldDiscussion -topic $1 & PID=$! if [ $PID != "" ] then sleep `expr 3600 \* 24 \* 5` kill -KILL $PID fi fi That would limit "periodic discussions" to 5 days (top)...
