Pharo5.0.app on macOS X Sierra 10.12.3 can't write to changes file
by Marco A. Feb. 24, 2017

Feb. 24, 2017

>From http://pharo.org/download, I clicked the nice blue "MacOSX" button to download the Pharo5.0.app. As the little javascript alert warned me, I placed it into /Applications folder and launched. I saw the black screen that many people have written about, and I get an information window with the following message "Pharo cannot write to the changes file named /private/var/folders/ph/6q54clts6y7czjnhc0vxpct40000gr/T/AppTranslocation/58A28E84-EC87-40E7-B87E-11E24533A93B/d/Pharo5.0.app/Contents/Resources/Pharo5.0.changes. Please check that you have write permission for this file. You won't be able to save this image correctly until you fix this." I have an iMac (21.5-inch, Late 2013) running macOS Sierra version 10.12.3. I tried chmod 777 on the changes file but it didn't work. The World menu > System > About... shows "Pharo5.0 Latest update: #50770". When I try to quit, throws an exception also. Can anyone give me guidance? What am I doing wrong? -- View this message in context: http://forum.world.st/Pharo5-0-app-on-macOS-X-Sierra-10-12-3-can-t-write-to… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Feb. 23, 2017

Hi, I'm having a hard time finding documentation on how to copy a portion of a ByteArray to/from another portion of a heap allocated C byte array with UFFI. My current reference is https://ci.inria.fr/pharo-contribution/view/Books/job/PharoBookWorkInProgre… Thanks for directing me at relevant docs or examples and sorry in advance if I missed some important point in the docs.

Re: [Pharo-users] Crash in Athens
by Alexander Samoylovich Feb. 23, 2017

Feb. 23, 2017

Hello. I can reproduce the bug "semi-automatically". The tree classes I use to crash are attached. Run AthensFlyingStickMorph new openInWorld and wait. Sometimes it crashes immediately. Sometimes I have to wait a couple of minutes. If I done not resize the crash never or almost never happens.

Data Encryption
by sergio ruiz Feb. 23, 2017

Feb. 23, 2017

I have been tasked with throwing together a small web app that will hold the passwords to different projects for my company. I would like to use seaside to do this, but the biggest requirement is that we need to be able to either: - encrypt the entire database, so that if the machine was compromised physically, the data would be useless. or.. - encrypt the username and password fields to facilitate the above, also. i am thinking that the first option might be easiest to implement. any ideas on how i would pull this off with pharo?

Voyage: Unique vs Multiple repo
by Hilaire Feb. 23, 2017

Feb. 23, 2017

Hi, I have three questions regarding these two options. As a matter of analogy to what I know, for me a Voyage repo is like a database and collections like tables in relational db world. So what is the argument to use multiple repo for an application domain? When using two repo A and B, is it ok to have instances saved in A with attributes saved in B? When fetching instances from A, will these instances get their attributes saved in B right? Thanks Hilaire -- Dr. Geo http://drgeo.eu

Strange behavior

Feb. 22, 2017

Hi everybody, The Finder has answered my question but the proper answers were sort of hidden in a heap of apparently insignificant answers. I'm sure it's useful and I would like to understand how, if someone is gentle enough to tell me. Cheers, Mark

Feb. 22, 2017

Hi, after 3 minutes working, I'm in a situation where a System Browser window cannot be closed. While the button is there, with tool tip and visual feedback, clicking it simply does nothing. Minimization and maximization still work. Is there a way to force a close?

[Versionner] Including remote packages
by sergio ruiz Feb. 22, 2017

Feb. 22, 2017

Hi, all.. I am creating a configuration using versioner.. as part of this configuration, I need to include packages (which donât have a configuration) from a remote repository.. i initially brought the class in from monticello, and included it, but i ended up with a configuration line that goes like: spec package: â<package A>â what i really need is something likeÂ spec repository: â<url to repo>â spec package: â<package A>â or, is there a better way to set up my project?Â Should that main package (which would probably be useless outside the configuration) be hosted together? ideas? thanks! ---- peace, sergio photographer, journalist, visionary Public Key:Â http://bit.ly/29z9fG0 #BitMessageÂ BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV http://www.Village-Buzz.com http://www.ThoseOptimizeGuys.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

Latest Voyage for Pharo4
by Hilaire Feb. 21, 2017

Feb. 21, 2017

Hi, I need to test Voyage for a project in development but... installing Voyage on Pharo4 with Seaside already installed (from Pharo4 configuration) produces a broken Seaside installation. Voyage installation installs Seaside-core, which in turn break the installed Seaside. It is strange Seaside is needed by Voyage. Is there a way to get a recent Voyage installed without altering an existing Seaside set up? Thanks Hilaire -- Dr. Geo http://drgeo.eu
