Popularity and Success are not the same thing

After my last post, I went back and read through Giles blog post again. I missed his main point, and I dismissed what he had to say far too quickly. This video of DHH and Tim ferri, drove the point home for me and is well worth watching. This talk didn't prove as half as successful at Rails Conf, as Bob Martins.

Whilst I still think that Giles point is tangential to what Uncle Bob had to say, I think it is a profound one. That is, that any proclamation that requires free thought is likely to be unpopular. This lack of popularity doesn't equate to failure however, it just means that such ideas are more likely to benefit the few, rather then the many.

Uncles Bob's use of Smalltalk as the epitome of failure, rather cleverly raises the spector of fear, and as we all know fear is the great motivator of the masses. So if as a Ruby programmer, you want to be in a job for the foreseeable future, then make sure and do TDD. It's kind of like a Mom using threats to make sure that the kids eat their greens.

Whilst DHH and Tim and Paul Graham, are fundamentally right, they don't address the psychic of the average mainstream programmer, which is mostly dominated by the fear of not finding a job. So in a way this brings me back to were I started. Sometimes being right isn't enough. Sometimes you need to be effective too, and whilst fear is the worst of motivators, Uncle Bob is addressing the world as it appears to the vast populous, which is an effective tactic.

The world that is Giles reality is a rarefied place and the few people and languages that live there are likely to remain obscure for some time to come yet. The last interesting point is that it appears that DHH has out grown the community he created. This is hardly surprising. Like I say followers don't think for themselves, they rely on others, and as Rails becomes ever more popular, the community will become dominated by followers, just like what happened with Java.

For someone like David, this influx of non-thinkers must be nauseating.

What Killed Smalltalk: Sometimes Balls can be Useful

Uncle Bob, has been his usual charismatic and entertaining self in his keynote speech this year at Rails Conf. He presented a dire warning for the Ruby Community: "What Killed Smalltalk Could Kill Ruby, too". So what is this beast of death? Well Uncle Bob blames the ease at which programmers could create a mess in Smalltalk as the thing that killed off the language, quoting no other then Ward Cunningham to back up his argument. Interestingly he makes only brief mention of another VM based OO language with garbage collection that appeared in 1995, and was market mercilessly and given away for free, whilst Smalltalk vendors were still charging £3K plus per pop for Smalltalk licenses (yes that's over £3000 per seat). Hmm...

Anyway as you would expect, the Smalltalk community is up in arms. James Robertson has this post. And Giles Bowkett makes this response entitled "What Killed Smalltalk: My Balls". Giles response, demonstrates IMHO complete ambivalence to what is actually happening in mainstream programming today. Whilst IMHO Uncle Bob clearly has his finger on the pulse. I have never been a full blown member of the Smalltalk community. I've always been one of those people on the side lines, using Smalltalk for fun and hoping to get a Job that would allow me to write Smalltalk commercially, but never being fortunate enough to do so. I think that gives me a more balanced perspective. I am neither a curly bracket or square bracket zealot, having lived most of my programming career with both. Whilst I've always admired the Smalltalk language, I have noticed that the Smalltalk community has a tendency to be insular and inward looking (with no sign of those balls Giles speaks of). Anyway, here is my comment in response to James Robertsons blog post. I thought I'd post it here (with some minor edits), since I know that very few people take the time to look at Smalltalk blogs:

There are two audiences here. One audience are the 20 somethings who were merely a lusty glint in their fathers eye when the clash of C++ and Smalltalk was taking place in the 1980's. The other audience are the people who where actually there.

For the 20 somethings, I think there is a lot in this presentation to get excited about. First of all it makes the point that good ideas can fade. It also makes the point that great languages provide the programmer with great power. With this power comes responsibility. As developers we have a choice. We can allow ourselves to be dumbed down and given dull tools so we won't hurt ourselves, or we can become responsible and disciplined to the extent that we can be trusted to use sharp knives. This message is an important one. The other great message, Smalltalk, which is now being discussed amongst a new young audience. If any of these young kids are half as curious as I was at their age, then we should expect downloads of Squeak to spike this weekend...

As for the other audience. The people that were actually there. It is easy to dismiss this presentation as a pile of BS. Well it mostly is, but to engage with it only on a factual level is to miss the point. This presentation is not for us. Bob Martin is not a Smalltalk programmer and never was. I was on one of his OOD courses in the 1990's and he asked who in here as used Smalltalk? I was the only person to sheepishly raised my hand. He then went one to castigate Smalltalk, saying that you couldn't use it for anything serious because it would lead to a mess once you got to more then 10K lines of code. Back in them days Bob was a curly bracket language zealot.

I'm glad that James has admitted that that back in the 90's the Smalltalk community suffered from arrogance too. I read Giles response and it sounded more like a tirade. The mainstream developer community at the moment is in flux. They trusted in vendors only to be let down. Now they are looking for new leaders. Most of them are followers, if they weren't they would have self educated themselves long ago, and Uncle Bob wouldn't be able to get away with his historical inaccuracies. The Smalltalk community are in a great position to provide leadership. The Agile movement came from Smalltalk, TDD from Smalltalk, Ruby from Smalltalk...

So why isn't the Smalltalk community doing so? Why wasn't a Smalltalk programmer giving this keynote instead? Where is Alan Kay when you need him or Dan Ingalls? Is it because we've all got a reputation of being grumpy old men? It is up to the Smalltalk community to make themselves relevant to these new young kids. Bob is doing his best to tell a story second hand. The Smalltalk community should be telling this story itself. Looking in the mirror at yourself and your own short comings, is much harder then pointing fingers at others.
