human being, humanity, human animal

The first step towards moral progress is to replace the word “human being” and “humanity” with “human animal”.

HTML “html”, “head”, “body”, Tags Are Optional?

Perm url with updates: http://xahlee.org/js/ex/html_head_body_optional.html

HTML “html”, “head”, “body”, Tags Are Optional

The HTML's “html”, “head”, “body”, tags are all optional. This is a test page. View source.

However, the “DOCTYPE” and “title” are required.

Check validator.w3.org

However, it is not clear whether html5 requires them. See: http://dev.w3.org/html5/html-author/.

It says:

The html element is the root element of a document. Every document must begin with this element, and it must contain both the head and body elements.

...

In the HTML syntax only, both the start and end tags are optional, and so for convenience either may be omitted, unless you wish to specify attributes on this element, in which case, at least the start tag needs to be included.

It appears that the “html” tag is optional, but “head” and “body” are required.

360 Panorama

Xah Lee, 2011-03-29

Discovered a new, really great, panorama site.

The site got thousands of panoramas around the world. It uses Adobe Flash technology, and works really great. Best of all, you can embed them on your website.

Women with Nose Cut Off

Xah Lee, 2010-02-01, 2011-03-28

Time Mag in its 2010-07-29 issue is running a cover with a lurid image of a woman with nose cut off.

The image comes with a big caption: “What Happens if We Leave Afghanistan”. The logic of the juxtaposed caption is clear: if US doesn't meddle with other's affairs, then the world would all cut off women's noses.

The mag tries to justify the image on cover, but i didn't see any justfication for the caption.

What is Taliban?

After writing this blog, due to the lurid photos, i looked up on Taliban. Here's Wikipedia article: Taliban.

Taliban is a extremely fucked up religion based military sect. In a sense, it is similar to WASP and George W Bush of USA, Tibet under Dalai Lama, Scientology & Falun Gong.
