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

Hi, Yes. We will be testing these days and we will come back with more details. Two more questions: - Is minheadlessVM now integrated in the regular VM binary or are the two different artifacts? - Also are the platforms from https://github.com/pharo-project/opensmalltalk-vm/tree/pharo/platforms representative for minheadlessVM?

Hi Doru, can you give us more insight of the errors? Because there should not be changes in the behavior of the VM. Maybe there are issues, we have used the Pharo tests as a guarantee and we are laking some tests. Cheers, Pablo.

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

by Tudor Girba

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)
