[Sugar-devel] ASLO shut down target date? (was: licensing question)

Hi, Dave

I appreciate the attempt to discuss this issue.

My take is that James is reflecting his view that there is no difference 
between Sugar and a Sugar activity - they all get built together. I am 
ignorant of the benefit of using Debian or Fedora packaging. The xo 
bundle is a zip file and is not dependent on packaging. This may have 
some benefit in building SOAS.
By the way I mean 'live' as in a live cd which can be booted without 
touching the host or used for installation.

For the past decade, Sugar builds have been released with a selected set 
of activities. Normally the set in OLPC builds has included as many 
activities as there was room on the XO (fewer on XO-1 than the other 
models).  This apparently from an assumption that once distributed, 
users have no opportunity to add new activities.

Actually, ASLO provided that capability. However, the XOs in Peru and 
Uruguay (by a deliberate use of the root password to prevent it) did not 
have realistic access to ASLO.

When I volunteered in Nepal, it was immediately obvious that the limited 
storage of the XO required a school server - a local computer with 
content that can be downloaded to the Journal as desired and then 
deleted when not needed. So one of the requirements was to provide a 
local version of ASLO (http://schoolserver/sugaractivitie). This has 
been available for several years.

This year I decided on a major project to update this capability by 
fixing broken activities and providing as rich a library as possible. 
The priority changed with the release of Ubuntu 18.04 LTS which does not 
support gtk2. Fortunately Gtk3 is essentially syntactic sugar requiring 
no logical changes to the activities. I suspect that gtk2 activities 
which work on an XO also work on Sugar with Ubuntu 16.04 - but the LTS 
feature is compelling for dealing with the problem.

The entire ALSO library including all activities in the github repo 
requires only 5GB. With a current laptop with an Ubuntu installation, 
this can easily be installed on the local computer (I use 
/home/username/aslolite). This is a powerful opportunity - every 
activity is available to be fixed, making a new version level. It is 
easy to write scripts to test every activity for conformance to 
standards (e.g. which activities use class instead of exec or are gtk2 
or web or Gtk3).

In my experience about 50% of the activities do not work. This platform 
provides a base for quickly testing activities on an XO and recording 
whether they work or not and providing some comment about the problem. I 
used the platform to test the xo bundles created from the github repos. 
The ratio of 103/191 fits this experience.
