[Sugar-devel] Network version of Abecedarium: why and how

[lionel at olpc-france.org]

Hi Gonzalo,

 

Hmmm, interesting. You’re right it’s a good way to explore to reduce the
package size.

Plus, most of the times images are displayed in the game at maximum 70% of
the real size. So, I’m not sure reducing quality will be visible.

I’m going to try. 

About list of contents, it could be find here: [1].

 

Best regards from France.

 

                Lionel.

Hi Lionel,

Almost 65 MB are in the html/images/database directory, I think you can
reduce the size of these images to 1/4 of the actual size, just saving as
gif or jpg and playing a little with the properties, without loosing too
much quality.

I tried with one on gimp, but you can use imagemagick or similar to
reprocess all the directory

Look:

[gonzalo at localhost abc]$ ls -l 

total 152

-rw-rw-r--. 1 gonzalo gonzalo 19228 abr 24 17:59 accountant2.jpg

-rw-rw-r--. 1 gonzalo gonzalo 16029 abr 24 17:59 accountant3.jpg

-rw-rw-r--. 1 gonzalo gonzalo 21789 abr 24 17:56 accountant.gif

-rw-rw-r--. 1 gonzalo gonzalo 28391 abr 24 17:57 accountant.jpg

-rw-r--r--. 1 gonzalo gonzalo 62549 dic  9 22:57 accountant.png

 

(accountant2.jpg is with quality 70% and accountant3.jpg with 50%)

I don't know about the audio, but maybe is possible improve there too.

 

I would like have the list of words represented on these images on pootle. I
imagine many activities 

can use this if is a shared resource.

Hi all,

 

I’ve released last week my Abecedarium activity for Sugar 0.96+. One issue
with this activity is that, due to number of contents (1500 images and
sounds), its size is about 100Mo.

 

We want to deploy the activity on our Nosy Komba deployment this year: 150
XO-1 and 50 XO-1.5.

Because we’ve got other activities to deploy, we compute:

-          The free space on a XO-1 and XO-1.5 with Sugar 0.96 without any
activity: 550 Mo for XO-1, 2645Mo for XO-1.5.

-          The size of all activities that we planned to install, see the
spreadsheet [1].

Unfortunately 100 Mo is too big for the XO-1 with some other big activities
(GCompris, Tuxmath, TurtleArt, Speak, 
).

 

So I choose to develop a new version named “Abecedarium Net” [2] without any
content included, so with a size of only 6Mo.

The idea is to deploy all contents on a school/web server instead of into
the activity. A config file in the activity has to be set with the URL of
the content, or it could be set from a dialog popup. The activity test the
network regularly and display the status.

Because Abecedarium is wrote in HTML5, deploying the web server just mean to
copy the content of the full activity on the server.

I’ve explained the full process in the activity description.

I will test it myself on our School Server at Madagascar but do not hesitate
in the meantime to test it and give me feedback.

 

Best regards from France.

 

                Lionel.
