"Fast growth has its problems." I don't think we need to worry about that. Even if we're successful with a marketing campaign, it will take time to aggregate substantial numbers of new Smalltalkers. It may take years to reach the top 20 on Redmond. (We should be so lucky to have this problem.) Building an ecosystem is not about funding. Developers (and businesses) write new and useful libraries out of need *when they choose to use your programming language*. Ask yourself this: Smalltalk, in its various flavours, has been used commercially for more than three decades. After all this time, why are there still useful libraries missing, libraries that you find in the Java and Python worlds? Can you honestly tell me that over the next 5-10 years, we'll see the gaps in our library ecosystem filled in? I wouldn't bet my lunch money...

But fast growth also has its problems... https://www.groovehq.com/blog/scaling Particularly see point 1) "Scaling Shifts Your Teamâs Focus" I believe Pharo is still in a stage where it needs a lot of agility. IF there was suddenly a large influx of newbies, then EITHER: * the experts spend *all* their time answering newbie questions and not moving the platform forward (with a wider pool of disruptive opinions) OR... * the newbies are ignored, get a bad experience, leave, and then "tell everyone else about it". Currently early adopters of Pharo get the benefit of great support from a direct line with the experts, which enhances their good experience which they can report to others. However it takes time to grow a community to have a range of middle experience levels to buffer the experts so they can continue to do *real* work to drive the platform forward.

Its catch-22. This "bring them and they will build it" has similar trouble as you concern against "build it and the will come".

Python was in the doldrums for the first 13 years of its life. Then, it exploded onto the scene in 2004 (according to TIOBE). Was this because of continuing improvements to CPython during those 13 years? Really? JavaScript has been around since 1995, but what made it the darling of the web in the past 5 years? Hard work? What hard work? (Serendipitously, Google launched AngularJS in 2009. Maybe this was the impetus?) What about Ruby? Twenty years old, it only exploded onto the scene in 2006. What did Rubyists do in the first 11 years to cause this jump in popularity? If it all came down to hard work, then why didn't Haskell and Erlang and D rise to the top? Are those communities made of laggards and deadbeats? Of course, we should work hard to improve the platform. However, that by itself is no guarantee people will adopt it. Python's success was *serendipitous*, to be sure. To suggest that it was inevitable because of all the work done to improve CPython is not clear. kilon.alios wrote > bingo !!! > +1.000.000.000 > > The problem is that there is so much hype about marketing thats easy to > miss the enormous fact that languages like C, C++, Java and Python are not > as popular as they are even with their big flaws without substance , > without solving some serious problem that requires serious resources . > Foremosts those languages have been evolving for decades , take Python > > and I am NOT talking the language itself I am talking the most popular > python implementation and the oldest , CPython, its 24 years. > > Let me repeat this... > > CPython IS 24 years OLD !!!! > > There is none smalltalk implementation that I am aware of that has been > actively developed for so long even though smalltalk as a language is far > older than that. > > Now imagine where Pharo will be in 24 years.... wow.... it blows my mind > just trying to imagine. > > And by the way Python had ZERO marketing , ZERO!!!!

For iPad, it is gone because I did not renew my developer license, so Apple remove it from the store. Sorry sorry :( Concerning DrGeo on Android, I mostly forgot all the details to build it as I did not update it since a couple of years (3 years). Historically Dmitri Golubuvsky helped me a lot to build it [1]. But I don't think he's working on it anymore. Later Jannick Laval asked me how I did the DrGeo for android, he wanted to try for Pratch, he wrote some notes you may find useful [2] You may want to check the former source repository containing Android package for Dr. Geo, I just open its access for you [3] You may need the event VM glue code[4], not sure this is the most recent one. I am just writing from memory, so I may forget some key points. However, in the long term a lot will have change in Pharo on Android: - What I did was before Athens, I don't think Athens is working now on Android - Bloc will very likely replace Morph, and it may be the think to use for Android perspective.

Yeah I am interesting to this too, I was not aware Dr. Geo was on Android thats great news. Hilaire why I cannot find Dr. Geo for my iPad mini ? Just got an iPad mini as my Christmas present to myself :) I would love to see a blog post by you how to get Pharo working on Android and iOS . Any pointers ?

You should understand that I put a LOT of Did you check out what can be done for/with high school students with Dr. Geo, the Pharo interactive geometry application? Please take a look to the link below, in the second part of the document you have demos about interactive programming with Smalltalk to build mathematics models suited to senior high students http://forum.drgeo.eu/What-s-new-in-Dr-Geo-recently-tp4024786.html Many more fun models are easily do-able, but I am short in time there this recent months.

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 ?
