Answer 3

A service that will receive a link to an article from habra, and give it back to the generated PDF, simultaneously generating a QR code for downloading the PDF and with the ability to view it online (with a browser). The main thing here is to reasonably cache, and, of course, take into account the fact that the author could edit the article.
TCPDF+FPDF+Cron+Cache(APC+FILE)+PHP.

Answer 4

By JS:
Please write useful user scripts.
For example, for habr: on the main (and in any “blog”) only part of the article is visible before the habrakat, and in order to read the 2nd part, you must either open a new tab or go to another page in the current one. But I don’t want to do either, I want to read the news in its entirety without leaving the main page and even write comments on them.
There is a solution - use jQuery to load the 2nd part of the article right on the main page when you click on "read more". And when you click on "comments" open more comments. Well, so that the buttons "collapse comments" and "collapse the article to the cut" immediately appear.
In principle, the spmbt habrauser has already written such a script, but it is very buggy, and the author abandoned its development long ago.
I uploaded the latest working version (there were minor corrections in the code since publication, which he wrote to me via PM):
