Welcome! There are some advice in https://news.ycombinator.com/newswelcome.html

Try to make post in English, post in other languages are usually ignored or flagged.

Try to post technical stuff. Non technical post may be also good, but it's easier to pick good technical post until you get use to the quirks of the site.

In general, the main page of a newspaper is not a good post. A single (technical) article is better.
