Verbatim copying and redistribution of this entire site are permitted (except for those of pages, articles, photos, audios, videos, etc. that are licensed differently), provided this notice is preserved.

Retention of weblinks in both hyperlinked and non-hyperlinked media (as notes or some other form of printed URL in non-HTML media) is required.

Why this license?

This is because opinions should not be modified. Works that express someone’s opinion—memoirs, editorials, and so on—serve a fundamentally different purpose than works for practical use like software and documentation. Because of this, we expect them to provide recipients with a different set of permissions: just the permission to copy and distribute the work verbatim.


The website does not collect any personal information other than data you provide such as your name, your email address, your website address, your IP address, and your web browser’s user-agent information. All these data are kept encrypted and will never be shared with anyone.

All of the data you provide may be kept for an unlimited period of time but can be purged at your request in any time.

Server logs will be purged on a daily basis.

Personal views disclaimer

Any views or opinions expressed here at any moment are my own and not those of my employer, unless it’s specifically stated.

Furthermore, one of the benefits of having an open mind is that my thoughts and opinions will eventually change. There is no shame at all in changing personal views and beliefs over newly presented evidence.

All posts are published with no guarantee of safety. All posts are published as-is with no warranty whatsoever so only person who is responsible for any harm or damage in any way is you yourself.


I am not responsible for views and comments of visitors. If a visitor leaves a comment, that visitor (person) is responsible for the comment.

Embedded content from other websites

For responses to URLs, such as responding to a post or article, this site allows the storage of data around the post/article in order to generate a rich citation. Items such as author name and image, summary of the text, embeds provided by third-party site, etc may be stored and are solely to provide this context. I will remove any of this on request. Embedded content from other websites behaves in the exact same way as if the visitor has visited the other website.

These websites may collect data about you, use cookies, embed additional third-party tracking, and monitor your interaction with that embedded content, including tracking your interaction with the embedded content if you have an account and are logged in to that website.
