Re: [Pharo-dev] [ANN] Pharo Headless - Beta (Actually what is between Alpha and Beta)

Excellent news! I should say that for GT we are currently using the minheadlessVM (Ronieâs work) out of the opensmalltalk-vm repo (https://bintray.com/opensmalltalk/vm/cog) and it works remarkably well. We started to play with your minheadlessVM. So far it looks like there are differences, although I am sure they are not large. So, what is the difference between the minheadlessVM built by you versus the one from opensmalltalk-vm?

An old but insightful critique of Eric Raymondâs The Cathedral and the Bazaar by Nikolai Bezroukov

by Eliot Miranda

This may be old news. It was news to me and apart from being an excellent critique of tCatB it also includes many truths about large software systems and if open source communities in general. If you havenât read it already may I suggest it is well worth your time reading. https://firstmonday.org/article/view/708/618/ _,,,^..^,,,_ (phone)

(7.0.3) writing a large(?) string to stdout is mangled

by Dale Henrichs

I've run into an issue with pharo 7.0.3 where writing a string that contains embedded crs or lfs to stdout causes the output to be corrupted in odd ways. I have provided the details and a reproducible test case up on github[1]. Stef suggested I post the issue here as well ... Dale [1] https://github.com/pharo-project/pharo/issues/4266
