Metacello cannot download the latest zip of a github repo if a zip already exists from a previous commit

by Dimitris Chloupis

So it looks like that when I do Metacello new baseline: 'ChronosManager'; repository: 'github://kilon/ChronosManager'; load and I have ChronosManager already installed via the same command previously , if the repo has changed in the mean time , it wont get the latest zip from github and instead will use the existing zip to overwrite my image (Not cool at all). Obviously a bug ?

That's an *enormous* amount of work!!! No wonder it hasn't been done yet. I did identify one thing: get high school students (i.e., young people) interested in Smalltalk. That's why I tried (and failed) to launch the Canadian Smalltalk Competition. You should understand that I put a LOT of work into this, *a great deal of sweat and tears*. You have no idea. (Just ask David Buck of Simberon.) I'm only one person; I can only do so much by myself. And unfortunately, I'm coming to the end of the line.

Re: [Pharo-users] PharoJVM

Why is this "nonsense"? Are you saying it's not important to make Pharo applicable to more problem domains? Are you saying that making Pharo useful to more people in the IT community is a dumb idea? What am I missing in terms of situational awareness? Clearly, *I am clueless*, because I don't understand what you're getting at with Wardley maps. "Strategy means making choices." Are you suggesting that you've made hard choices? Whatever those choices are, *the results speak for themselves*. The IT community at large still ignores Smalltalk. Businesses are looking to Java and JavaScript and Python and C++ /before/ they ever look to Pharo. I don't know how you can deny this. I don't know how you can tell me it's working out well for Pharo.

The great goal is clear, but there are bumps on the road and there is no direct road to Rome. Your analysis of the situation is superficial and not helpful. Marketing is most effective if it is aligned with strategy. I was serious about you having to make those Wardley maps. It all starts with user needs. Take a look at where new smalltalkers can come from (students, old smalltalkers using something else, software reengineering specialists, people from small languages who want an IDE for it, people dissatisfied with their current large community language, etc), make some persona for them so it gets easier to imagine what their needs might be. Do the same for the people in our community (Researchers, independent developers, small group in a large high-tech company, legacy smalltalk group etc). To understand and explain why and when they might be persuaded to use smalltalk, read Mary Lynn Manns & Linda Rising, Fearless Change, Patterns for introducing new ideas Geoffrey A. Moore, Crossing the Chasm and possibly Mack Hanan & Peter Karp, Competing on Value From those user needs, make Wardley maps breaking down user needs in technology and community needs, making them more and more concrete. Identify what we support, where there are gaps and overlap, and what changes to expect. Then decide where you can with minimal effort have the most impact and focus your marketing message there, using a positive story. Measure impact, see what changed and repeat. Stephan
