I have to give credit where due. It's unfortunately rare for someone with a brand new HN account to immediately contribute so much relevant and substantive information. Very Nicely Done!

Your articles are well written, easy to read, and seemingly accurate (n.b. without me doing any due diligence to check facts), but the meme images are too distracting, even a bit annoying (this is most likely due to me being a curmudgeon ;). Of course, opinions will vary, and I'm sure others might say the memes break up the reading and help hold attention.

For notes, it's generally a poor idea to submit a bunch of good stories at (roughly) the same time, particularly if they're from the same site. Your submissions will be competing for attention with all other stories, including your own. Though your "101" article is currently sitting on the front page of HN, your second article "Dev Guide" suffers from the others' success. Spacing out your submissions, like one a day, will give you better results. Also, the HN Guidelines (link at bottom of most pages) ask for users to avoid submitting so many links that the new page is dominated by your posts.
