Do i really need to use the ide to 'get' smalltalk? I'm pretty happy with my tools, and would only use ST for the paradigm shift anyway. I don't want to leave my text editor. It has become a part of me, and i can't imagine life without it.
The linked pdf makes a number of factual errors. it incorrectly suggests that ketogenic don't encourage eating lots of vegetables and low-sugar fruits. It also trys to twist "not all calories are the same" into "you can eat as much as you want". and of course, trans fats should always be avoided.
I struggled for years trying to get in shape unsuccessfully before going on a ketogenic diet and losing ~100 pounds. It was kind of like switching from programming with memory to programming with values. It still takes hard work, but it feels like the odds are not as stacked against you anymore.
