Thanks! I will keep it in mind!

I see. Thanks for the explanation and the links! Unfortunately I pretty much do not know what Twitter is, either. So I looked at the instances (?) you suggested and pretty much saw a doom-scrolling wall of random postings, which I find exha

I tried that some time ago, but do not seem to be compatible with all the business stuff. Thanks anyway! :)

Thank you, but I do not even know what Mastodon or the Fediverse are. :) Could you point me to some resources that would get me started? Preferably to something for the social media-illiterate! Which software to use (on BSD), where to regi

In one of my other compiler books ( http://t3x.org/t3x/book.html ) I just use a template for the ELF header, but I still think it adds too much complexity. One reader complained about it.

Sure, no problem :)

I have multiple sources of income, but book revenues are the biggest one. The area I live in is a rather expensive one, but I pay no rent, which helps. By the standard of our country I qualify as "poor", but I do not mind much. A

My personal perspective is that computing has become much more complicated than necessary in the past decades. Of course abstraction will always create complexity, and some of that can hardly be avoided, but in computing these days complexi

Oops, good catch. :) Thank you!

Thank you! Books are my biggest source of income, but "big" is relative here: I am earning about $500 per month in revenues. This is mostly a problem visibility, I think. Most people stumble across my books by accident. Reviews, p

Thank you! The 2nd Ed. was quite an endeavor, I am glad you like it!

Cool! The one in the book is for the Z80, which is a bit older and does not even have multiply or divide instructions. The compiler can also output code for the 8086, though. And the 386.

Here it is, my latest compiler book! Basically an expanded version of "Write Your Own Compiler", this time discussing code generation for CP/M on the Z80 (instead of ELF on modern systems), which simplifies some things a lot.

My latest book, an homage to the times where a compiler could just spit out machine code. The text discusses and implements a self-hosting compiler for CP/M on the Z80.

I have written much more, more like 20, but not everything is still available. Then with a few books I ran out of motivation, so they just sit in my archive. At the beginning writing somehow fascinated me, but right now it is probably just

Sometimes I post here, sometimes on reddit. Mostly I have no idea how people stumble across my books, though.

The compiler uses the same level of optimization on both DOS and CP/M. It is self-compiled on both platforms. It uses DOS interrupts on DOS and BDOS functions on CP/M, but I/O is really not a big issue here. The DOS compiler

One of the guys "talking nonsense on an obscure newsgroup" here. :) There was no premise. I ported my T3X compiler ( http://t3x.org/t3x/t3x0.html ) to DOS and CP/M, self-compiled it on both, and was surpri

Small C was the inspiration for SubC, a project of mine. It is pretty much a cleaned-up and slightly extended rewrite of Small C that compiles with few warnings on modern compilers. Also comes with a book. http://t3x.org/sub
