Bernd Paysan's personal blog at bernd-paysan.de covers programming and systems. Since 2012, 15 different Hacker News readers have linked it 18 times, most often “Why I Use Forth (2015)”. No feed was found, so read it on the site itself.
Too few sampled comments (9) to say how often HN recommends it.?
Why HN links it
HN readers link Bernd Paysan's pages on Forth and stack-based processor designs, including the 4stack VLIW design, the b16 microprocessor and his Why Forth essay, usually as references in CPU discussions.
Summarised by Claude from a sample of 9 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
These projects seem really cool! A few links and historical references that might be of interest: > On the hardware side I want to use small and simple systems If you'd like to build a fully understandable computer, you might be interested in concatenative languages like Forth, Factor, and colorForth. These use a much simpler and more understandable, typically stack-based computational model that run on microcontrol…

HN discussionWith great respect to Doug McIlroy (in the CACM article), the shell pipeline has a serious problem that Knuth's Pascal program doesn't have. (I'm assuming Knuth's program is written in standard Pascal.) You could have compiled and run Knuth's program on an IBM PC XT running MS-DOS; indeed on any computer having a standard Pascal compiler. Not so the shell pipeline, where you must be running under an operating system…

HN discussionIt's possible to pipeline a stack CPU but the there is an upper limit on the number of pipeline stage that make sense. A forth friendly (data and return) dual stacked CPU can be very simple and small yet achieve a throughput close to one instruction per cycle. Going superscalar on a single datastack is hard. You basically have to rename every stack access and most compute instructions consume two arguments producing…

HN discussionThere have been CPUs with multiple datastacks e.g. https://bernd-paysan.de/4stack.html is a VLIW ISA with a very dense encoding and "just less ports" to the register file than a classic DSP.

HN discussionLook at for example the GA144 and similar tiny deeply embedded cores like http://bernd-paysan.de/b16.html , where the stack is implemented as a register file. Those cores are actually fast, but limited in capability and a nuisance to program.

HN discussionThere was a design for a high-ILP stack processor in the 90s: https://bernd-paysan.de/4stack.html but VLIW instead of superscalar.
