As someone who had a reasonable aptitude for mathematics in the past but essentially no practice in the last 10 years, it seemed like the content varied wildly in how well it built on previous chapters, or more generally adhered to the "introduction" label. The programming-based content was thin to the point of being pretty much irrelevant, leaving the whole as something more like a scatter-brained textbook for an odd curriculum rather than a refocused version of a sensible one.
Having experimented with IB on Azure, I can comfortably say that the problem is not so much the fabric but the general usability of Azure itself - hot garbage doesn't do it justice.
Whenever I consider entrepreneurship as an option for myself, it is always the customer-facing sales part which leaves me feeling like I would struggle.
Coming from the scientific computing realm, I've only ever done "real" code in Python until a couple of weeks ago when I was forced to do some work in Typescript. Once I got over the initial worries about the best method to install npm to avoid Python-esque problems and gave nvm a try, I was very pleasantly surprised by the package management process and was able to just get on with the work.
I've tried various Python env management solutions in the past (mostly leaning towards conda), but had recently settled on just using separate LXC/LXD containers for each project.
