Re: [Pharo-users] Smalltalk Programming Competition

by Tim Mackinnon

Hey guys - lets just try and give this some support - Iâd like to see something useful come out of it that hopefully can be applied to other countries. Iâd really like to see some kids enjoy programming. I once met one of the original participants of the Parc experiments who was ~14 at the time (he was much older when I met him). I commented that it must have been amazing, and he was a bit reflective and interestingly said that it almost ruined his life because while it was cool at the time - when they had to take it all away, he couldnât code in the way he had enjoyed for a further 10 yearsâ¦. Of course now we have an amazing environment, that not enough people actually know about, or take seriously enough - even though its produced most of what they take for granted today, AND is still busily pushing on things they will take for granted in another 1 years. Richard - give it a shot and inspire some kids (and inspire me with some interesting problems or setups that you think might work) I also notice that Kent Beck gave some support - thats pretty cool!

I do not diminish the efforts of open source contributors. I applaud them. My point was that, as a Smalltalk advocate, I worked on average 8 hours a day, every day of the year, for nearly 4 years. That is a tremendous burn rate, and I can tell you I am totally exhausted. Imagine if I had a *real*, full-time job. This effort would've literally killed me.

Re: [Pharo-users] Smalltalk Programming Competition

by horrido

Thanks, Ben! I did not know about CoderDojo. Yes, you have an excellent suggestion for a different strategy. It is certainly one that is worthy of adoption by another evangelist, and hopefully somebody will consider it. There are three concerns. First, CoderDojo seems to be heavily invested in Scratch, Python, and JavaScript. Whether I could convince them to include Smalltalk as a key technology in their curriculum is up for question. If it's only an optional, ancillary, or secondary technology, then it won't get the breadth of coverage that I'm hoping for. Second, CoderDojo is already well-established. There is little marketing potential here. My campaign has always been, from the very start, heavily marketing-oriented. My goal has always been to reach as many people as I can, in the shortest period of time, with the greatest impact. That's practically the definition of marketing. Third, the JRM competition is my last hurrah. After this, I shall no longer be a Smalltalk evangelist. I've worked very, very hard for four years and it's time for me to take a well-deserved rest. CoderDojo requires a longer-term commitment than I have energy for at this time. I estimate that I can just complete the competition within the next 8-12 months. Regarding the scholarship, yes, CA$2,000 is fairly rich, but college/university tuition is very, very expensive here in North America (I don't know about Australia). Much less than $2,000 and the competition wouldn't be much of a public draw (again, from a marketing perspective). I'm thinking of the world-renowned Waterloo math competitions with prizes ranging from $200 (most common) to a high of $500. That doesn't exactly tickle my nuts. Depending on the level of funding, I am prepared to scale back a bit from $2,000. If the contest is too chintzy, I won't be able to get local media interested.
