Great work people of course constantly improving Pharo pays off and slowly and steadily our community will grow , just see how active our mailing lists have become and also with creation of Swift language and the growing popularity of Clojure the importance of live coding emerges and taken seriously this a huge chance for Pharo grow as the best live coding environment.

Pharo is great for this. I don't currently develop software for a living. Earlier I was a systems administrator (including for software developers), and lately an electrical power engineer (https://au.linkedin.com/in/bencoman) But while some people like doing crosswords... I *love* programming, and Pharo is a joy to use. I've been surprised a few times when peeking under the covers how its possible to follow, understand and change the depths of the system. You can really feel you make an impact. I can't remember who famous said something like "The only languages worth learning are the ones that changes the way you think about programming..." and I found that with Smalltalk & Pharo. > I was very impressed by the nice welcome I have received. And I see there is > lots of useful work to do here. Some drive-by newcomers that generically complain "why doesn't my new tool (Pharo) work just like all the other conventional tools" do get short shrift. Such arguments follow a common pattern when we believe our differences are our advantage, so this keeps the noise down in the mail list. That said, we don't want to be insular, so fresh eyes providing *constructive* criticism are welcome. Come with an open mind, review and contribute code and you'll be very welcome. A good way to get your hands dirty is to review fixes submitted by others... https://pharo.fogbugz.com/default.asp?pgx=LF&ixFilter=45 There are never enough hands there :) (my own action here fluctuates from time to time) I learnt a lot of the system from reviewing other people's fixes, by using PharoLauncher to easily start two Images running side by side. In first image, I stop a <merge> of an issue's Slice half way through so the methods being changed are listed, then drop a #halt into some of those to trace the existing issue. In the second image I complete the same <merge> and drop a #halt into the same methods, and debug each image in lock step to see where code path differs. > So that's where I come from when you see me chipping in the conversation > here.
