Testing Summary: 3 March 2012 - Auckland, New Zealand
Who: Alana, Charlotte, Eliot, John, Fabiana, Oliver, Leslie, Tabitha, Tom

This week we tested build "29 customized" on XO-1.75 and "188 11.3.1-au" on
XO-1.5

Broken in os29 on XO-1.75 (details below):

   - Raised #11668 for record high quality video problems
   - We had several XO-1.75s hang while idle
   - Distance is still broken on XO-1.75
   - Yum complains the rpmdb has problems
   - wake-on-lan works well but prevents laptops from going to sleep, power
   logs are attached

Broken in au188 on XO-1.5 (details below):

   - Speak’s toolbar is squashed, see photo on picasa

   - Musicpainter on au188 still doesn’t work
   - Font in terminal on au188 still to big

Google Docs is still unstable on Browse on both builds but it’s better on
Firefox 10 on au188.

Last week we successfully installed a new wifi card in Tank, thank you
Sridhar for sending it to us! Next week we’ll do Poppy Copy.

Last week we tested au183 and among other things, we used Screencast to
record some Physics. Screencast seems to make the display update somewhat
jerkely. Encoding the resulting screencast took a long time and seemed to
stop at 35%, I don’t know if it aborted or the progress bar was mesleading.
Something appeared in the journal, but I couldn’t play it -- error could
not determine type of stra3. - gstypefindelement.c(8-984) …. Can’t typefind
empty stream. We will follow this up next week.

With os28 and several times in the last few months, I’ve noticed that the
wifi password window steals the focus but does not appear at the front,
worse, clicking on other windows does not restore the focus to the
front-most application. It appears to be an invisible modal dialog.
Switching to it with alt-tab brings it to the front and everything returns
to normal.

os29 on Clyde:

   - Physics- still does that lack of update thing when I draw a line - I
   see the cursor line but no line is drawn. I don’t seem to have this problem
   with the other shapes. The response time also becomes really really long if
   there are too many shapes!
   - Measure: waveform ok, fft ok. Tried sampling - I get the constant
   waveform and then  every 30 seconds it appears to freeze but only for a
   couple of seconds and then returns to the live stream. The sampled frame
   appears to be recorded in the journal. This means that one cannot start
   looking at the data until the experiment ends. It would make more sense to
   let the captured image frozen on screen and replaced every 30 seconds so
   children can do measurements on them or have a split screen. Can’t really
   tell if increase amplitude (bar on the right) is actually working
   - Paint: froze completely, with no screen refresh when switching
   applications. GDB doesn’t seem to work, it found two threads, but claimed
   both of them had corrupt stacks.
   - yum complains

Warning: RPMDB altered outside of yum.

** Found 1 pre-existing rpmdb problem(s), 'yum check' output follows:

mesa-libGL-7.9-6.fc14.armv5tel has missing requires of
mesa-dri-drivers(armv5tel-32) = ('0', '7.9', '6.fc14')

   - When you install gcc you get kernel-headers-2.6.40.3-0.fc14.armv5tel
   while the running kernel is version 3.0.19. Aftering writing a simple
   program in C with a couple of functions and loops, we find gdb behaves
   normally on this .

os29 on Sundance:

   - Record - photo ok. audio ok, movie on low ok for the full 2 minutes
   but quality very poor. Movie on high quality has noticeably slowed down by
   10 seconds and eventually stops. Raised olpc #11668.
   - Memorise 36 can play, create games save and play them- did not test
   collaboration.
   - Measure seems to work ok (same as in clyde).
   - Typing turtle: seems to be working ok.
   - Does not respond to shutdown through right click on cetral XO figure
   in the ring

os29’s Distance on Kid and Bonnie
Still very broken as reported earlier in #11596

os29 on Kid

   - paint works - tested opening from journal and activity ring, tested
   some tools

   - record works - tested picture, can open from journal and activity ring
   - maze works
   - fototoon works

os29’s wake on lan seems to be working well, but prevents the laptops from
suspending for very long. Two laptops on an adhoc network do go to sleep
but wake up frequently, 5 laptops on infrastructure wifi with internet
access don’t really go to sleep at all. Looking in the power log is
difficult because it seems to be written only occasionally? It also doesn’t
clearly explain that a wakeup is due to lan. Power logs are attached but we
didn’t take care to record what was happening when. Would such a test be
useful? My power log collector does not work on XO-1.75 :(

au188 on Tank  XO-1.5 C2

   - speak and robot works but the toolbar is squashed, see
   - maze works (didn’t test collaboration)
   - record works - high, low quality, video, audio and image tested
   - memorize - tested preloaded games, created a game but couldn’t save it
   so it is lost (very disappointing to lose your work, it’s not in the
   journal)
   - ruler works
   - music painter - no sound or play button doesn't work - cpu usage is
   now 100% and csoundxo is using it - as reported previously
   - moon works
   - clock works
   - poll works. improvements - ability to edit the questions and possible
   answers after you have saved it but before someone votes. good that you can
   hide the results as people answer so not influenced by other voters, would
   be good if you can view them without all votes being collected, and would
   be good if you could change number of votes required after voting has begun
   (so if you forgot to change from 20 you can fix the mistake). would be good
   if you could export your graphs with the title and column/row headers as
   images for use in portfolio or write to make reports and presentations.
   - arithmetic - did all levels and tested using addition and subtraction
   with an 11 year old, seemed to work, teacher in the background didn't like
   it as she didn't like the panic it created in answering questions
   - socialcalc - started entering data, tried to do some formatting and
   got the spinning wheel of death on the cursor and data can no longer be
   entered
   - spirolaterals -  tested on an 11 year old, she got it pretty quick
   with a bit of help, teacher likes this one and how you can experiment until
   you figure out the pattern, the child is doing some thinking aloud
   - system resources - what is the * for?
   - feedback - where does this go? how do i choose between personalized
   (american spelling) and anonymous submit? submitted something but don't
   know what that did, I saw the pulsing icon in the top left corner for few
   seconds

We’re using Browse to do collaborative editing of the testing report in
google docs, it’s not working so well. I’ve successfully done collaborative
editing for about 3 hours on a different wifi network with a different
document and different collaborators on an XO-1.75 with Browse, but
consistently, the testing report eventually encounters a slow script
warning and usually browse appears to freeze shortly after. This happens
both on the XO-1.5 with the Australian builds and on the XO-1.75. Perhaps
the slow script timeout is too long? Firefox 10 on Rosella (XO-1.5) seems
to operate google docs a lot better than browse. Not only is it much more
responsive but is much more stable. This isn’t an option on the XO-1.75
because Firefox don’t provide an arm build for Linux (they do for Android
but that does not help).

Kind regards
