If risc-v is successful, no need of those backdoor injectors which are compilers anymore (and absurd and grotesque bloats). Just write risc-v assembly without abusing the macro preprocessor.
ah, I see you too are a disciple of the kdb school

if you code in J for 6 months, you will no longer think in loops, and if you stay with it for 2 years, you will see that looping code was an artifact of early programming languages, ready to be displayed in museums along with vacuum tubes
Ah, after all these years, you've finally found it: a worthy opponent for kdb source code.

Breaking into q/kdb+
I am an experienced developer with 10+ years in various other languages (c++/python/ some scala). I am interested in getting into q/kdb+ after a recommendation from a friend in the industry. Does anyone out there have any suggestions on how to break into the industry Ive done the courses on https://code.kx.com/ and read a few suggested books but cant find any officially recognised certs I could get, and practical experience is limited ! Im not sure even id hire myself into such a role

Are you interested in learning about low latency zero allocation programming?
For the curious, when I first ran into it it looked like this. That is not minified code, it's how people who write K write Java code. It was expected you would take that file and include it in your sources somewhere. The KDB protocol is actually very simple, basically writes out the types with a type tag, length and then the data in binary.
What are some alternatives?
