Still no answer for .svg images, haven't really looked yet, but I will.

Some possibilities here for converting svg's to png's:

https://askubuntu.com/questions/709150/how-to-convert-svg-image-to-png
I tried it in inkscapelite and the results were pretty disappointing. Maybe Gimp would work better?

Hi jrb,

About converting a bunch of svg's to pngs', this seems very efficient:

for file in *.svg; do inkscape $file -e ${file%svg}png; done

per, https://askubuntu.com/questions/209449/is-there-a-way-to-batch-export-svgs-to-pngs

Untested by me.

I unsquashed the zdrv sfs of your latest iso, and managed to shave off 4Mb's off it resquashing it using this formula:
Code:
mksquashfs "$1" "$1".sfs -noappend -all-root -b 1048576 -comp xz -Xdict-size 100%
Source : https://techoverflow.net/blog/2013/01/11/create-highly-compressed-squashfs-from-folder
Don't bother trying the above on the full puppy sfs, it will ADD 2 Mb's.
But on the zdrv, it shaved quite a few bytes. Why?

Thanks musher, but sadly Crying or Very sad the compressed size of the .sfs's doesn't matter in terms of computer performance. As a matter of fact, the more compressed they are the slower the bootup. What really affects the computer is the amount of ram they use once uncompressed. On a low ram computer if they take too much it really slows things down. But a nice piece of code anyway.

It's interesting that some files compress a lot and some hardly at all. Maybe how they're coded?
Hi jrb.

Indeed, the amount of compression of an sfs file per se is of little
importance for computer performance. I thought I'd mention it because
of your comment, and perdido's, about bandwith.

Also, I'm sure you heard of the recent movement on this forum in favor
of putting Puppies on a diet, initiated by our forum collegue "oui", to
rival Slitaz and TinyCore in size?

As to the reason why some squashed files are smaller and others not,
using the same parameters, according to the author and a couple of other
sources, it's because smaller files can be put in the "gaps", and bigger
files cannot. (My understanding.)

At any rate, contrary to my colleague "oui", I have no problem with a
Puppy offering all the necessary tools to make the user's experience a
pleasant one, even if offering these tools makes Puppy bigger than what
I call the "anorexic" distros.

Finally, I don't know if it's the kind of experiment you'll be interested in,
but I followed peebee's suggestion here. I removed the "all-firmware"
directory and its contents, and there was no penalty. Peebee was right.

BFN.

Thanks mikesir,

I tried that with inkscapelite and it worked, but all the images came out with no background color. Could touch it up I suppose. Then I tried installing the full inkscape and quickly got into dependency hell. I'll see about using gimp later today.

This is actually a .png but that wouldn't attach.

I don't know if oui has checked slitaz and tinycore but their software is roughly the same era as Precise. Slitaz has ldd-2.14.

Yeah, I tried removing the firmware as well and it works fine. Will be in the next .delta. Wink

Hi again jrb,

I had intended this post first but thought the other might be more immediately helpful. For converting individual svgs to pngs I use LibreOffice Draw. But that's a PITA if you have lots of conversions.

Congratulations on a very nice Puppy. It should prove very useful on older, low-spec, computers. Although I was testing it on a quad-core, I think these results were significant. It booted to desktop using only 84 Mbs of RAM, and using Mike Walsh’s Seamonky-portable was able to play a Youtube video using only 200 Mbs. I'm posting from it now.

I do, however, have a couple of recommendations. Precise was created before shinobar published the revised pupsaveconfig, 2.2.5, http://www.murga-linux.com/puppy/viewtopic.php?p=457081#45708. Without that update, shutting down without triggering an Automatic Save is difficult (I don’t know enough to say “impossible”).

The first thing I do when I test a Puppy is see if I can get on the internet using wifi. SMP reported finding no Wifi networks and I thought there might be an absence of drivers or firmware. Frisbee, however, saw my network but could not connect to it. The installation of rerwin’s updated networking applications solved these issues. See http://www.murga-linux.com/puppy/viewtopic.php?p=952876#952876 for all applications noting:

“UPDATE 11/15/18:
Uploaded the final version of SNS 2.1, functionally identical to the beta but with minor code cleanup. The set of current packages that are part of the upgrade:
network_connect_update-20180930
simple_network_setup-2.1 [replaced by 2.2.1]
network_wizard-2.0 [replaced by 2.1.1]
frisbee-1.4.9 (unless omitted entirely) - from above link
pgprs-2.0.2 (unless omitted entirely) - from above link
quicksetup-20170612 (optional, to use the CRD option - not needed for xenialpup 7.5).”

The only other suggestion I would make is to include tadky’s Pup-SysInfo-2.8.5, http://murga-linux.com/puppy/viewtopic.php?p=579411#579411. Its presence makes it far easier for newbies seeking advice to find and communicate necessary information than having them execute terminal commands.

With the exception of the latter (itself small) applications, substitution for the originals will add very little weight (if any if you choose to publish an updated ISO.

I have to confess that I'm a total ignoramus when it comes to WIFI (or ethernet for that matter). I live in a remote rural area. My internet comes in by satellite and my router wifi is open since no one lives close enough to steal it. And I know and trust everyone who lives along my road.

I do use public access wifi when I'm traveling and I have yet to run into anything that peasywifi can't handle. I use to use SNS before peasywifi came along. Some of the acronyms you used flew right by my head.

If people start complaining about not being able to connect I will have to throw myself on the mercy of someone more knowledgeable, perhaps yourself, rerwin or rcrsn51

I will upgrade SNS. I think peasywifi is up to date, I'll check to make sure.

I will definitely include Pup-SysInfo, an excellent suggestion and I will play with pupsaveconfig and quicksetup and if they work well I will include them.

Thanks for the input, any more suggestions will be gladly received.

Cheers, J

Hello Volhout.

I know you addressed your questions to jrb, and I do not know feh. But
would the following approach the answers you're looking for?
Volhout wrote:
(...)If you change wallpaper using the menu, default is not updated. So you
end up with conky backgound of default wallpaper always.
(...)
Try changing the line in the conky configuration file to
Quote:
own_window_transparent yes
(Remove the "no"; line 23 or thereabouts, if you're using my conf file.)

Volhout wrote:
Any idea where I can find what the current wallpaper is ?
Failing all else, the current wallpaper is always indicated on the 3rd line in
the PuppyPin file at /root/Choices/ROX-Filer. Try grep or awk if you need
to fish it out? Something like:
Code:
grep backdrop /root/Choices/ROX-Filer/PuppyPin
(Provides the entire PuppyPin line.)
OR
Code:
awk -F">" '$1 ~ /backdrop/ { print $2 }' /root/Choices/ROX-Filer/PuppyPin | awk -F"<" '{ print $1 }'
(Provides the exact path and file of the background image.)

IHTH

PostPosted: Sun 14 Apr 2019, 21:20    Post subject: First .delta update  

I am issuing the first update using a .delta file. I will repeat myself here:

Put the original precise-light-5.7.1+0.iso file and the precise-light-5.7.1+0.iso___precise-light-5.7.1+1.iso.delta file in the same directory.
Click once on the .delta file and then click "Generate" and its a done deal. Cool

md5sum of .delta file = 48b8acb6b37af2955aae46a0f6c91b8e
md5sum of new .iso = f68a98bf29e55666418c0a2b9aa25f58

You can click on the blue lettering in this post to download either one. I will also post the new .delta on page one.

What's new in this upgrade?
updated sns
installed Pupsysinfo
updated transmission - libevent
updated findutils
updated diffutils
updated guess_fs
updated peasywifi
added GDmap_preview
added dir2pet_rtclk
added dir2sfs_rtclk
added Nathan Wallpaper Setter
fixed Firefox crashing problem
md5sum_txt on the right click "Open With" menu. Will create md5sum for any file

removed peasyscan because it wasn't working. Sad Not its fault, I have to figure out what bits of Xsane it needs to work

Enjoy, J

Hi jrb,

Downloaded the delta file twice and it did not match the md5
The md5 of both of my downloads was the same md5sum=48b8acb6b37af2955aae46a0f6c91b8e

Google chew it up?

Shh, don't tell anyone, especially musher. I just downloaded the .delta and tried it. It made precise-light-5.7.1+1.iso with exactly the same md5sum as the original.

Embarassed I just checked the md5sum of precise-light-5.7.1+1.iso against what I posted, they're the same. Time for a rewrite of post one.
