Hello, I've been collecting random blog posts and notes during the past years and while I was evolving as developer and professional.

There was a separate website for this collection wiki.summercode.com; but in 2018 I decided that it's too much to support an independent domain and it's time to simplify my IT infrastructure and make it faster (by precompiling everything into static HTML).

So, I've have saved many articles and different programmer's and administrator's blog posts. I collected them from the full range of websites around the world. I called this section as 'wiki', because previously (prior to 2018) it was built with my fork of the git-wiki project.

Some of this blog posts are not available anymore, and it would be great if my collection could help anyone, despite that many items in it are outdated.

A note to authors or content owners

If you are an author or owner of the content published on this site and you don't want to grant me privileges for doing this, please contact me. Anyway, we try to leave the original link to the website of each article re-posted here.
