Enlaces previously met with a OLPC and Brightstar representatives asuring a total of 1000 XOs. We went on to develop the proposal and negociate where to deploy the iniciative (Enlaces required us to engage rural areas, outside of the Metropolitan Area, among others): http://wiki.educalibre.cl/index.php/Propuesta_OLPC_Chile Unfortunately, as you can see, the proposal was frustrated, because as Brightstar distributor and partner of the OLPC Foundation, argued that it would not be possible for the Chilean State to purchase only 1,000 XOs, but would consider a minimum of 10,000 XO.

I like the idea so far, but here are the issues I have with the current implementation: 1. HandleViewSource should return a boolean to indicate whether the request was handled or not. This would also get rid of the Python-specific dbus error handling code in viewsource.py because handle_view_source in activity.py could simply answer False. Hmm, but we still need to handle the case where a non-python activity hasn't implemented the method, right? Oh certainly, the logic is sound, it's just the not implemented Pythonism there that is not necessary. 2. GetDocumentPath is a poor name for what it does. It should contain source because it's not the document that is viewed, but its source. How about GetSourcePath()? Well, the idea is that, by default, sugar will show the activity's source. This method is intended for displaying a textual representation of the sources behind a document, be it html for browse, logo for turtleart, etc. So perhaps getDocumentSourcePath()? Sure. Also, this file is deleted unconditionally when the source view is closed. I'd add a boolean transfer_ownership flag to indicate that it's okay to delete (similar to the datastore API). Sounds good, if activity authors think this added complexity is ok, I can add it. Well, it's more complexity to having to make a copy just so Sugar can delete it ... Also, what kinds of source does this support? I noticed the Browser's HTML source was highlighted. Is that determined by the file name extension? The sugar shell tries its best to display a formatted view of the source code based on the extension and the contents of the file. Currently, it uses gtksourceview2 for that. If an activity author would like an improved or new formatter, we should talk to the upstream maintainers to add it. It's quite configurable and should be a matter of editing some xml files. Also, the call could additionally answer a mime type which would override the guessing. On a more general note, activityservice.py should be annotated with the actual DBus signatures.

I don't see how it would be inconsistent that when an activity
saves a
title meta-data property which obviously is a string, and it
resumes, to
expect it will be returned as a string and not magically converted
to a byte
array. An activity should not have to care about the DS's internal
representation.
I don't see what stops an activity from storing a sequence of bytes
that doesn't conform to any text encoding. The DS won't be able to
index it, but should it reject the entry?
How is the DS expected to return this sequence as a D-Bus string?
We are talking only about the mandatory, well-defined meta data
properties. If an activity stores an invalid string, it is buggy, and
bad things are expected to happen.
What
will happen to eToys or other activities that expect all titles come
from the DS as UTF-8 strings?
The activities will break with badly encoded byte arrays too, because
they will try to decode it as if it was a UTF-8 string.
For custom properties you could state they must be byte arrays, but
for the
known properties it certainly is more appropriate to use the actual
data
type.
What's the actual data type? The type that the activity provided
when the property was first sent to the DS? Or the convention we used
in the older DS?
No, the type defined by the contract between Sugar and its Activities.
This is something like the 'title' property is a utf-8 encoded string
specifying the main title to be displayed in the journal list. Am I
the only one who would find mentioning of byte arrays in that spec
ugly and unnecessary?
A byte array is not a string. Or vice versa. If you disagree, ask the
D-Bus designers why they did put in a string type instead of simply
using
byte arrays.
This is a matter of naming. In some environments, a string is plainly
a sequence of bytes. In some others, strings are sequences of bytes
expected to contain textual data in some specific encoding.
Oh please, it is not just a matter of naming. Think, for example,
about how you would compare two strings, and how you would compare two
byte arrays. Or how you would present a string to a user (developer)
vs. a byte array.
Besides, we use high-level representations to aid reasoning about
what's going on inside the computer. By dumbing down everything to the
lowest possible representation you are removing valuable semantics.
I can't believe I am really the only one on this list who thinks that
Sugar should be explorable all the way down. If we collectively
thought that byte arrays are as fine as higher-level constructs, why
would we even be here?
And after all, the meta data is declared to be a{sv} instead of
a{say}
precisely to accommodate appropriate types for the values.
Can you extend on what you mean by accommodate appropriate types for
the values?
To use the string type for properties that are text strings, to use
the integer type for properties that are numbers, to use the boolean
type for properties that are truth values, etc.
I mentioned it before, and I still maintain that this is an abuse
of D-Bus.
Things that are strings should be transmitted as strings. If
nothing else it
makes debugging a lot easier - strings will be rendered as strings
by the
various D-Bus diagnostic tools.
As I explained before, Things that are strings means that someone
needs to decide what is a string and what not. And if that someone
aren't the leafs, then others need to be communicated of this decision
and act accordingly. I'm not sure which benefit brings all this
complexity.
I think you are only seeing the complexity it would add to your
datastore implementation, where I only see the conceptual simplicity.
So, pretty please ... with sugar on top ;) deliver the strings as
strings.
I personally don't care so much about the D-Bus API being perfect,
because we have already agreed that a POSIX-based API could work even
better.
So if by:
- stating on the API docs that some fixed set of properties are to be
strings and the others byte sequences,
- and raising an exception when an activity feeds it something that is
not a string
activity authors can be made significantly happy, I can do that.
Don't bother, unless someone else supports my ramblings.
Most activity authors wouldn't notice anyway because they do not use
the datastore directly. I made Etoys deal with the byte arrays. I'm
not sure there even is another non-Python activity

Best in what sense? It indeed is easy enough to make Etoys cope with

implementer of a non-Python activity.
The inconsistency could be really confusing.

I think Tomeu point is that the DS should know nothing about the type
of the metadata properties and interpretation of the data blob (the
array of bytes) should be left entirely to the activities.
It's not a data blob. The mandatory meta-data properties are well
defined. This is (or should be) part of the Sugar specification. Like,
the Journal has to agree with activities that the meta data property
named title is actually a Unicode string. It is *not* left to the
activities.
Besides, if you throw away the knowledge that something is a string,
then you lose quite a bit of useful information. Like, full text
search pretty much requires knowing what is a string and what not. You
may want to read about comparing Unicode strings - it certainly is not
as simple as comparing byte arrays. Let alone if we want to do fuzzy
search.
And after all, the meta data is declared to be a{sv} instead of
a{say}
precisely to accommodate appropriate types for the values.
Yeah but the interface was written for a datastore which had a notion
of metadata property type (although a very bad one). The new one does
not.
Then change the API signature and do not pretend it did not break.
Any comment on the debugability concerns?

Did the interface change? I think tomeu new datastore actually has the
same dbus interface...
Well, some of the API uses variable types, so even if the interface
does not change literally, changing the types involved poses a problem.
E.g., meta-data properties are declared as dictionary with string keys
but arbitrary values (a{sv}). In practice, all meta data values are
strings. They used to use the String (s) D-Bus type, but now Tomeu
changed it to byte arrays (ay). This is breaking Etoys resume which
reads the title property and expects a String but gets a ByteArray.

This is very bad for activities like Etoys, the ones produced by Pippy or activities that would prefer to display the source code for the _content_ loaded in that moment (Browse). Alternative 1: Move it to sugar-toolkit, would be available to all python activities, and activities would be able to override it easily. Inconvenient: non-python activities wouldn't benefit from it. Alternative 2: Add a mechanism for the shell to know if an activity wishes to provide its own view source window. It could be done by adding one more D-Bus method or by adding one more property to activity.info. Inconvenient: adds complexity to activity development. Opinions? This would definitely be an improvement :) I'd add a DBus method to the activity protocol answering a boolean. If the activity answers False (or does not implement the method) the system would do its best to show the source.

Can somebody confirm that this field is no longer of effect, so we can update the wiki page and expectations, or if this was an oversight, can we discuss what we really want? I don't really know what's the expected behavior after the home view redesign. Taking it out from the favorites view is pretty easy, but the activity can still be launched form the activity list view and the journal which has the same problems. I guess the activity needs to be visible in those places because are the way of managing the bundle. I have an idea :) When you click the icon of an activity marked as no-launch, the shell/ journal could bring up the object chooser pre-filtered by the activity's supported mime-types. Then the user could choose which object to read or view, and the activity would be started with that object. This could actually be an entry in the palette for all activities that have a non-empty list of mime-types (labeled Start with ..., inserted just below the current Start). If that was the case, then the only difference between a regular and a no-launch activity would be the default action invoked when clicking the icon, regular activities would invoke Start, the others Start with Of course, we might deprecate the show_launcher option and rename it to something else to better convey its intention (requires-document?). The shell (and bundle builder) should generate a warning when installing an activity that is marked as no-launch but has an empty mime-type list. - Bert - ___ Sugar mailing list Sugar@lists.laptop.org http://lists.laptop.org/listinfo/sugar

There was a pilot project done in Mongolia that was run by the Japanese gov't where they introduced Linux to 4 towns. The students went on to study at the Mongolian IT college and apparently failed all their courses. The outcome was that these students were not prepared for real IT. Personally I feel that this is bogus and that it is the notion of IT, education and learning that need to be examined at the university level as well - however - just as I have learned when trying to reform educational methodologies there is a need to meet the norm half way (at least) and work from within - it would be nice if the OS could be designed in a similar gentler manner. Teachers, parents, gov't officials and many others are concerned that the computer doesn't conform to their expectations of a computer. Bear in mind that there was a lot promised in this computer like collaboration and mesh and the crank (everyone asks about the damn crank) that are still in development and all get lumped into the understanding of the OS. Essentially, in the minds of these people, fluency on windows, being able to do power point presentations and surf the web is what being prepared means. - I think if we could make some things a little more straightforward like saving, storing and accessing files (in the way PC users and Mac users can sort their way out in the opposite OS pretty intuitively) it would help bridge the gap to traditional expectations. Well, the XO already goes way more than half-way towards the popular notions of how computers should work. Almost all the software stack is identical to what you find on an arbitrary desktop. Demanding that it should go even more towards what is currently hip in this very immature field of IT doesn't sound too compelling if the goal is to empower future generations to use computers as malleable tools for thought, rather than as enslaving magical devices for office work.

Re: [sugar] Some extra information for Etoys translation
IMHO the comments in the POT are not explicit enough for a translator to understand their meta nature. They should have examples. Also the phrase could be made to stand out better. Maybe a common prefix, and use all upper-case? PO_LANGUAGE_NAME might alert the translator better than Language-Name which looks like any regular phrase: #: TRANSLATORS: Put in the name of your language, NOT the translation of language name. E.g. Español or Русский. msgid PO_LANGUAGE_NAME And since Etoys does not use a single font like Scratch does, why do we try to mimic it? - Bert - Am 02.09.2008 um 02:02 schrieb Yoshiki Ohshima: Thank you, Sayamindu, By the way, while trying to copy the extra information from Scratch to Etoys, I found that some translators translated the keyword, when they are supposed to provide the information.

Even if not exposed in the cp UI we should at least have an hidden preference. We have no way right to customize sugar profiles but we should have one. Marco I'm interested by the (implicit) idea that (all?) settings modifiable through the control panel should also be customizable. However, as I pointed out not long ago, some care needs to be taken to restrict the ability of the customization process to violate our security principles. As a strawman, how about using a convention or technology similar to http://thedjbway.org/daemontools/envdir.html to record the key-value settings that make up the bulk of the 'customizable' features? I'd rather use GConf which is what all the software we depend on uses and understand. I'd rather not tie Sugar too closely to Gnome.

Naturally, this is somewhat the opposite of what we want to happen when running in fullscreen on screens of various resolutions, in which the subcomponents within the UI should independently scale or not, as appropriate. There's a fair amount of work to be done there as well, to make sizes and proportions appear correctly no matter the resolution.

Could you name an example of such an Activity? It seems to me that the presence of any such Activity represents a design bug in Sugar. In the case of Chat and Journal, these are known design bugs. Chat will eventually be rendered mostly obsolete by pervasive overlay chat, and the Journal is planned to be merged into the Sugar interface itself. I pretty much agree with that. With the exception of activities that Ben listed there is no reason to include more in Sugar itself. For example the browse activity - this endorses one specific browser implementation, it pulls in one huge chunk of code, etc. It is likely that if hooks are added for opening URLs that they are specific to that one browse implementation. If there were several browsers, developers were forced to agree on some API. Competition is good, so we should not pick one flavor over another. IMHO it is better to clearly separate the core from the activities. This also forces clean interfaces, you cannot as easily chicken-out when breaking the API (and silently fixing the included activities). We want to encourage third-party activity development, keeping the core as small as possible seems beneficial to me. - Bert - ___ Sugar mailing list Sugar@lists.laptop.org http://lists.laptop.org/listinfo/sugar
