I get so confused by mcz to git migrations, even for my own projects, that I'm often tempted to delete the original repo even though I know that's terrible form. I wish there was a flag in the StHub model, but a note is better than nothing to prevent unnecessary work as here. ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

That is an excellent question. The catalog is apparently the best thing we have so far.

Hi eno On sierra I removed the Freetype plugin because it was crashing too many times (apparently in Pharo 70 this was fixed) then now I have crash when typing. :( Stef On Mon, Dec 11, 2017 at 6:08 AM, Eno <tgkuo1(a)gmail.com> wrote: > yes, you are right, it's caused by wrong VM, since by default, my images are > opened by pharo 5 VM, I cann't change to pharo 6.1 anyway without manual > effort.

Thanks marcus. Should I update all the pages of the lectures and other to use https?

Hi I hope that one of these days we will release the package manager for Pharo. Now in the mid time I encourage you to publish to the Catalog.

Package Discoverability

by Evan Donahue

Hello, I was wondering what the current story was for releasing packages so that they can be discovered. I'm trying to get into the habit of finishing and releasing all those 90% complete projects lying around, and so I wanted to know what the standard process should be for releasing a package of general interest. Especially now that iceberg is a thing, should I make a smalltalkhub page too just for people to search for? Should I submit it to the pharo catalog? Send a note to the mailing list? Any other best practices? Thanks, Evan

Looks like you've been busy! I was going to ask why these updates aren't being pushed an OpenSSL repo shared with Squeak, since things should not be much different at this low level, but actually it was hard to determine which was the original repo. I see... http://www.squeaksource.com/SqueakSSL.html seems to have not beenupdated since 2012. cheers -ben I've also added tests for SHA256 similar to the snippets above.
