Math equation formats

I need to store equations in a text file, in a source format that can be converted to something that can be rendered (e.g. mathML). I like the format used in OpenOffice. I don't want to use TeX, or at least I don't want to pull in all the baggage of interpreting TeX. What format does OpenOffice Equation Editor use, and are there 3rd party command-line converters that will process this format? I don't want to have to run OpenOffice every time I need to render/convert my equations.

Why are camera files typically prefixed "DSCN" or something similar?

I've noticed that files from my digital camera are always saved on the SD card as DSCN####.JPG. Some other cameras also save with this naming scheme, but others yet save with the prefix DSC, and sometimes even other strings. Is there any significance to these prefixes? Does it mean anything to the computer when importing the photos? And why do different cameras use different prefixes?

What are .md files?

I often see files with a ".md" extension. I usually open them with a text editor like Gedit and I can read them just fine.

So – why do they use .md files and not say .txt files? Can somebody explain how .md files are different from regular .txt?

I did a web search but all I came across were wrong references to a "moneydance program file format".

EOL in Notepad++ and Notepad

I'm using Notepad++ to create some text file, but I noticed when the generated file is opened in Windows Notepad, the file contents get mal-formated due to the fact that Notepad++ use LF and EOL character, while Notepad expects CR + LF.

Is there any way to change this behavior in Notepad++??

I have an archive of old(ish) tracked music in various formats - .mod, .s3m, .it and Commodore 64 .sid files.

I'm specifically interested in a format with support for a variety of tags (a-la-ID3).

Tell if a .gz file is really gzipped

What is a nice command-line trick to tell if a .gz file is really gzipped, as opposed to being a non-Gzip file just named that way?

Are you allowed to come up with any desired file extension (for Unix, Linux, Windows)?

I want to create a file called "message" that contains text only. How does the system know what program to use to read it if I decide to call it:

• message.txt?
• message.dat?
• message.enc?
• message.cpz?
• message.asdfasdf?
• message.abcdefghijklmnopqrstuvwxyz?
• message.this_is_so_random?
• or just 'message' with no extension?

I was wondering this for text-only files, but what about files that contain video and audio?

Who decides if file format is popular enough to have its own MIME type?

Who decides, if a program is popular enough to have its own MIME type?

How is that determined? Who decides, if srt is popular enough to have its own listing in IANA MIME list?
