You can so copy the datastore object out of datastore. Actually this way can be done only in a environment where normal linux desktop is present. Actually this way is not suitable from Soas or real XO. The code about this will be release in the next days. Cheers, Torello. Wow! a fuse module would be terrific!

[Sugar-devel] [sugar-devel] Recent fiddlings with Print Support
Okay, so here's the latest dope. Assertion: abiword 2.6.8 might be the best stable out there, but its a nightmare for my project. Reason: It requires an intermediate conversion, and the final pdf which is achieved doesn't have text that can copy/pasted (bug) Correction: Avoid 2.6.8 for the deployments My new code is version independent anyway, And if we can Avoid 2.6.8, we won't have to worry about text being drawn as image artifacts; they will be drawn as text only.

Re: [Sugar-devel] [IAEP] How Can We Showcase Turtle Art Portfolio
I'll be sure to have my camcorder ready... and my understanding is that Saturday's presentations will be streamed live On Wed, May 13, 2009 at 12:23 AM, John Tierney jtis4...@hotmail.com wrote: Hello All, Would like commentary from the community on how we can try and showcase the abilities of Turtle art Portfolio along with the things each of us are working on. The email below came from my inability(due to my confusing question) to start the thread in our IRC marketing meeting today. I hope those of you going to Paris get a chance to spend some time on this subject. This is an important piece of our Educational Outreach and a capability that all community members can showcase. Therefore, I have cross-posted to IAEP, Developer, and Marketing-please pass along to others who can be of help to the conversation. Thanks, John Tierney Hi Walter, Sorry I wasn't so clear in my question was just trying to start thread about importance of Showcasing TA Portfolio-The Journal and TA Portfolio combination for Teachers ability to see child's work and progression is one of the themes we should push. The idea that every activity integrates with the Portfolio is great selling point for teachers. When developers and activity designers discuss and describe their work mentioning it integrates with TA portfolio reinforces key concepts of reflection and critique and allows for children to showcase their creativity for Parents, Teachers, Peers and Community. From the non-technical/developer world I am not sure if it works with all activities. Showcasing and featuring the TA Portfolio as an additional assessment source which allows children to let their creativity shine is an important thing to get across. Allowing all community members to market this ability(Helps or Works with TA Portfolio) will help bring many more Teachers and others into the fold. Having a little session with the members at Sugar Camp Paris and with OLPC France about TA Portfolio and its ability to help Teachers and Students and the Programs ability would be very beneficial, even more so if it was recorded. Much like Evangeline's and your presentation at Sugar Camp it was one of the most instructive pieces on how this ability can make a true difference in the classroom. Now that the TA Portfolio activity has been realized, putting forth it's usability seems advantageous. Just an idea- Spot on. The reason why I give all my talks using Turtle Art is exactly to make this point of closing the loop. -walter ___ IAEP -- It's An Education Project (not a laptop project!) i...@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/iaep ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel
[Sugar-devel] Quoting in shell scripts (was: Re: [sugar-devel] Recent fiddlings with Print Support)

I hope you don't mind me pointing out a few oversights in your script
publically. The main reason is that I want to remember others (e.g. GSoC
students) to be careful about quoting - a topic that unfortunately
doesn't seem to get as much attention in university courses as it
deserves.
sandbox=${TMPDIR-/tmp}/cups-odftops.$$
(umask 077 mkdir $sandbox) || exit 1
TMPDIR and thus later sandbox may contain any character, so you need to
quote them.
BTW: I usually issue set -e in front of any script and explicitly
handle the cases where I know that some command may fail and I _do_ want
to continue, BTW. Doing it the other way round increases the likelyhood
of forgetting to check for an error and thus making the real error hard
to find.
fn2=`echo $fn1 | sed -e 's/odt/ps/' `
This invocation is the reason for this mail: You should (*) quote both
fn1 and the result of the calculation. This would give:
fn2=`echo \$fn1\ | sed -e 's/odt/ps/' `
As you see, it's a bit awkward. That's why I recommend using $(...)
instead of `...`:
fn2=$(echo $fn1 | sed -e 's/odt/ps/')
The given sed invocation will replace the _first_ occurence of odt
(e.g. Godtfred Kirk Christiansen.odt - Gpsfred Kirk
Christiansen.odt) , BTW. You should append $ after odt to make it
match just the end of the string.
if cat $fn2 | grep -q %!PS-Adobe-3.0
Useless use of cat: you can use shell redirection instead:
if grep -q %!PS-Adobe-3.0 $fn2
break;
Hmm, I don't see any loop that could be aborted. Do you mean exit 0
instead?
(*) For this particular occurence, it isn't strictly necessary to fn1,
as it is passed to echo which will behave the same either way. This
isn't true for most other commands, so it's useful to develop a habit of
always quoting arguments if they may contain arbitrary / unknown /
user-specified data.

While we are at it, I believe it is safer and more elegant to use mktemp
than $$ (which in theory can be captured by evil-doers using simple ps
on a very slow system). Also, I usually avoid subshells to not risk
hiding failures (you need to do set -e inside each subshell).
Here's my suggested variant of above:
sandbox=$(mktemp -t cups-odftops.XX)
mkdir -m 077 $sandbox || exit 1
Enjoy :-)

Re: [Sugar-devel] Quoting in shell scripts (was: Re: [sugar-devel] Recent fiddlings with Print Support)
Thanks. I have taken into account your suggestions and made another script.
This had been not a competition to beautify or verify the rigidity of the
script, rather to see if opensuse accepted it. Which it still doesnt
Something to do with lp user file create permissions.
Though the script works fine on ubuntu and fedora.
And also, this is my first shell script
#!/bin/bash -e
# CUPS filter to process ODT files using abiword
# $6 happens to be the path to file passed as argument
fn=$6
#in case its not defined
TMPDIR=/tmp
# we are creating a dummy folder, which can take different file types using
mkdir, change to =/tmp/cups-odftops
sandbox=${TMPDIR-/tmp}/cups-odftops.
(umask 077 mkdir $sandbox) || exit 1
#our two dummy files
fn1=$sandbox/temp123.odt
cp $fn $fn1
# Call abiword quietly, securely
abiword --to=ps $fn1
fn2=`echo $fn1 | sed -e 's/odt/ps/' `
#check if our version doesn't require an intermediate conversion, if it
does, do it, else break;
if [ -n `grep -q %!PS-Adobe-3.0 $fn2 ` ];then
abiword --to=doc $fn1
abiword --to=ps `echo $fn1 | sed -e 's/odt/doc/' `

cat $fn2
#remove the sandbox folder, for debugging purposes check by commenting the
following line and see what is in the /tmp/ folder
#rm -rf $sandbox
#NOTES: CURSE me for not realizing that these scripts cant write to anyplace
other than tmp dirs, and wasting about 20 hrs doing all sorts of
combinations of selinux tweaking, writing sample scripts (which magically
did the job) and CHMODing

Re: [Sugar-devel] dumping datastore to another filesystem
2009/5/12 Sameer Verma sve...@sfsu.edu: Is there a script that will dump all objects from the sugar datastore to another filesystem (FAT or ext2)? Dragging and dropping objects one at a time from the journal onto the USB icon is painfully slow.

[Sugar-devel] Activities in Sucrose release cycle
Hi all, Do we really need activities in Sucrose release cycle? Think about issue with last Browse which doesn't run on sugar 0.82 (but old Browse from 0.82 didn't have needed feature). Another problem - small but valuable fixes(like updating i18n for example) deployers have to patch it by themselves. Or in common, new activity versions in sucrose-0.85 release cycle, are they so 0.85 centric that 0.84(0.82) users cant use these versions. These versions could be 0.85 centric but we could wrap all sucrose related differences to toplevel API in separate package (I use sugar-port for this purpose[1]). For example on 0.84+ ObjectChooser(from sugar-port) will use preselected mime type but on 0.82 only fake(errorless) code. In that case activity authors can follow this API and write sucrose independent activities.

Above means that you override if it was defined. Use this instead:
TMPDIR=${TMPDIR:-/tmp}
Or use mktemp which has same fallback (and more!) internally.
# we are creating a dummy folder, which can take different file types using
mkdir, change to =/tmp/cups-odftops
It is common practice to keep lines maximum 72 characters long, to avoid
them wrapping in e.g. emails.
sandbox=${TMPDIR-/tmp}/cups-odftops.
There is absolutely no improved security in 4x$. $$ resolves to the
current process id, which (on most systems?) is not random but
aequential so relatively easy to guess by evil-doers. simply means
use the same process id twice.
My recommendation was to use mktemp with a _skeleton_ value that
includes , which means add a random number that is 4 characters
long.
(umask 077 mkdir $sandbox) || exit 1
If a system for some reason fails to set umask, above command silently
continues!
