Thanks, looks interesting on first sight
In the meantime I did some googling and found some relevant sources.
A good resource I just found is a little essay called
An Incremental Approach to Compiler Construction.
It's basically the perfect read when you don't where to start (together with
Let's build a compiler, which I mentioned earlier and is more appropriate as a first hands-on introduction to compilers)
Some other, more advanced works (that resemble the classic Dragon Book a lot more) are:
Understanding and writing compilersBasics of compiler designCompiler construction and
another one with the same titleModern Compiler DesignThese are the ones that seemed most useful after a first glance. The last six resources all seem to cover more or less the same topics and somewhat resemble the Dragon Book in selection of topics: the difference is that the Dragon Book is more of a 'complete reference'-thing: it is about 1000 pages. This goes for all but the last one: this is a solid read containing 800+ pages. There are of course more complete lists with references to compiler construction resources, these are the ones that look useful to me (and other with similar programming experience).
My plan is to read/skim though some of the shorther resources and, when I feel certain about myself, actually implement a compiler for a simple language (but we all know that this is easier to say than to actually do, so this may take some years or never happen at all).
