Well, like I mentioned in my other comment, I really liked his book Rust in Action so I signed up for his course, despite the price. But yeah, maybe it _is_ a scam at the end of the day.
Not yet. I'm willing to pay for stuff like this. I was reading Tim's Rust in Action at that time and I liked the book so when he announced that he was starting such a course I immediately singed up, although the price was a bit crazy. I got the coupon code from a guy on Reddit so that's pure luck. I am really willing to pay for other peoples IP. I am still hoping that one day he could complete the project but before that I've got some other projects to work on.
Side note: I've finished Build your own Redis in C/C++ (https://leanpub.com/build_your_own_redis) and it's pretty decent. The title of the book is a bit weird since it's almost 100% C++ so I don't know why they put "C" in there. But it's a pretty decent book (and reasonably priced).
One thing I want to add is, it's _not_ my job to reach out to him asking for an update. It's his job. If he could maintain a monthly (or even quarterly) email list with all the updates it would be a way better communication strategy.
Of course I did. I DM'ed him on Twitter with no response. Then I commented under one of his tweets and he did respond. He mentioned it would be complete by Aug 2023 (this was before Aug 2023). Some time this year I commented under one of his linkedin posts asking for update - no response. There are multiple comments from other users on that web page I linked above - most of them had no replies.
Of course he's been busy. Everyone is busy. But charging $200 (or $100 with coupon) for a course which is delayed for more than 1.5 years and still has no sign of completion is another story.
This reminds me of Tim McNamara's course Implement RougeDB, a Redis clone from outer space (https://learning.accelerant.dev/view/courses/implement-rouge...). I paid somewhere around $100 for this course (through some coupon code, I remember the original prices was $200-ish). It was supposed to be completed by Aug 2023, yet almost one year and a half later, it's still incomplete. I almost gave up at this point.
I really wish the Perl 6 -> Raku change could let it catch up with other languages such as Python.
Edit: sorry for the confusion. I meant popularity-wise. I wish the change would clarify to people that Perl 6 and Perl 5 are basically two different languages and people should at least consider Perl 6 as an option when they start a new project.
