This may be too late to this thread to matter, but I've been dabbling with GT for a few months, and I like it so far. I'm using a few of the modalities mentioned in the article. I use it as for "Pharo development" / Smalltalk IDE. I've tried a few times to learn Pharo and Smalltalk, but I've stuck with GT more than I ever had with raw Pharo. It feels nicer graphically, and, most importantly, it lets me write notes about what I'm doing and exploring and save them as part of the image. That means I can open GT and continue right from where I left off, even if it's been a month since I looked. I use it for "Personal knowledge management", mostly. Little projects and analyses that occur to me. Nothing fancy, things like writing up why it's easier to get heads-tails in a sequence of coin flips than heads-heads, with a bit of simulation, a writeup of the Markov chain, derivation of expected times, etc. I've done that many times before, but it feels good to have it all together in an aesthetically-pleasing form. Bits on game odds, leetcode-ish algorithms exploration, general computational fiddling. Once I figured it out, I like the git integration for both code and notebook pages. That goes a long way to reassuring me that the things I do won't be lost. I still don't quite get the Metacello / BaselineOfX dependency management, but I'll get there. I did a little API browsing, mostly following the "Exploring the GitHub REST API in 7'" video by Oscar Nierstrasz (https://www.youtube.com/watch?v=-vFwfwy5WZA). That series is excellent and I think does a good job of illustrating the power of the system and how it's different. But, in general, it feels like a good "tool for thought". |
