HN readers are very interested in new programming languages, but the way this post is written is not the best way to present your work. Your best bet would be to add some pages to your website that give more of an intellectual (not commercial or promotional) exposition of your project: how/why you came to work on this, describing the design choices involved, and giving a nice set of real examples for people to look over. Make sure to put a few code samples on whatever page you submit as the link to HN, because that's the first thing people will look for.
On your github it says: "The Lax programming language is used to create programs for Linux, operating systems, and kernels, and Lax is used for direct execution by the processor.". I don't understand all of that, but if you went into detail about what you mean there, that could be interesting to people.
Emphasize what's different about your language, i.e. what design tradeoffs you've made, and how they make certain kinds of programs easier to write. That is always of interest.
Don't make dramatic claims and don't try to 'sell' your language to HN. Our audience is pretty cynical about being sold to. Rather, try to interest them intellectually (and let them to do the selling part themselves!) You won't get far asking for help to promote your language, but if you interest the community, you might awaken a wish to participate.
If you use HN Search to go through past threads on "The $LANG programming language" (with $LANG as whatever language name), you'll get a sense of which types of posts do well and generate the best discussions. (Edit: well here you go, I did it for you: The $LANG Programming Language - https://news.ycombinator.com/thelang, https://news.ycombinator.com/item?id=46610557.)
Edit: here are a few comments users have posted in the past in response to new-programming-language posts - they give an idea of the kind of things one should take care of in advance:
