From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

what the heck!! that is so wild, mind blowing, i thought the main difference between raster graphics and vector graphics was the quality but i didn't think about it too deeply.

i had no idea svg files actually used html code and pretty much could be modified using only text and amazing code woa!!! this opens up the possibility for so many things on linux i think.

for example, on a linux distro, we could modify the desktop environment and make it waaaaay lighter by getting rid of jpg or png icons and just using pure svg on it.

svg can be given a lot of attributes like movement, mouse hovering, change color, change anything. and most svg files are still under a megabyte. wow.. please let me know other fun facts about svg or eps files. i really like doing graphic design on linux and inkscape.

Ommigod, these kids :)

SVG comes XML (a more coherent/simple version of the SGML that is behind HTML), and specifically from a time where people took XML and made it hyper-complicated with a flurry of extensions and specifications (look up "xml namespaces" "xslt" "xml schema").

The most apparent difference between SGML and XML is than in the former you write tags like without a corresponding , and in the latter you have to close them like (which is shorthand for ).

So... today you learned that what you learned earlier today was close to truth, but not true :)

PS: A lot of document formats are undercover/zipped XML (eg. the libre office documents, IIRC microsoft's .xlsx and .docx). This is not dissimilar to how json/yaml are widely used today.

So, my Lemmy app - and I think a lot of Lemmy, renders markdown, so whenever you write "<...>" It disappears for me!

I tried adding backslashes to escape, it still looks fine on lemmy.ml but your app may be bugged (and possibly vulnerable to xss? can you see the script block after the closed bracket?) alert('you should not see an alert')

It all looks good now :-)
