I am impressed with Puppy Linux but unfamiliar. I just wanted to make sure that you are aware of 7-zip, which is available for Windows and Linux. It gives the best compression that I know about. On Windows it's 30% better than plain ZIP with ASCII text. Don't know about binary or how it compares to bz but you should look at it.

Here is G2's Todo list
http://www.goosee.com/puppy/wikka/GuestTooToDoList

Are you happy with the way things are or is it worth setting up a wiki list of "dotpups to create" where people can ofer to take a file/project (leaving the name and time to be dotpupped by)?

It will also leave people an opportunity to suggest files . . .
If anyone feels this is a good idea they can set up the wiki page . . .

Cool

The suggestion was not to include 7-zip "the application" - though I guess it would have to be included in order to pull off the idea.

The idea was to employ 7-zip as the actual compression tool which handles the puppy distro itself (the main system files). Because it is better compression, Puppy could cram more stuff into the distro.

Thank you.

you could try http://www.linuxfromscratch.org/patches/downloads/linux/
linux-2.4-lzma-1.patch
linux-2.6-lzma-1.patch
mind the cpu overhead I have not tested yet (some time this week)

Hi,
In my experience (on windows but the principle is the same) 7-zip compression is very slow, but high compression ratio. I think Puppy uses gzip, which is pretty much the fastest [de]compression popularly used. Unfortunately I am fairly sure 7zip decompression would slow Puppy to a crawl.

As I understand it, Puppy is only compressed (I prefer the word 'condensed') on the CD. Puppy is uncompressed (or reconstituted) when it is loaded into RAM, so it would run the same no matter which compression algorithm is used. Different ones might load Puppy faster or slower into RAM from the CD, but I doubt the difference would be noticeable.
