Re: Wellington testers + Activities vs 8.2-759

2008-09-06 Thread NoiseEHC

  - Associating to an AP using WPA is extremely unreliable. Some
 laptops do, some after a few tries, some never. Likely to be the
 timing bug that has been discussed before.


   
There is another bug somewhere in the network stack. With my Belkin PreN 
router (MIMO chpset), every connection attempt fails which is initiated 
automatically (asks for a password which almost never works). When I 
wait until the XO gives up connecting and then click on the AP, it 
succeeds 100% (gets the password from networks.cfg). It looks like a big 
fat race condition to me, but unfortunately I do not even know where to 
start looking at the source so I will not fix it that is sure.

Yup, it will. It's already in the latest 8.2 build.

 or does the name 0.82.1 imply it's
 for a future OLPC release 8.2.1?

Nope. We expect that OLPC will always include the most recent 0.82.x
available in their 8.2.x releases.

 (I looked at various release/roadmap
 docs, none explains any relationship between them.)

 About my XO in Build 8.2-759 says I have Sugar 0.82.

Hm. I'd probably consider it a bug. It was supposed to mean 0.82.x but
it would be probably better to use the version of the latest Sucrose
release.

Re: [sugar] [Activities] Camera raw mode (WAS: Panorama activity)

2008-09-06 Thread Nirav Patel
It supports Bayer RGGB8, which should be basically unprocessed data
off of the CMOS.  I can't imagine it being useful though.  It would
require unBayerizing it to display, even though the XO's display is
also Bayer (I assume pixel offsets and swizzling would mess it up,
even if the colors are in the same order).  You're better off letting
the camera do the heavy processing and just get packed RGB back.

wireless lights on the XO : what should they do?

2008-09-06 Thread Samuel Klein
So we can control what the 'wireless' lights on the XO display / what
causes them to turn on and off.

I'd like wireless lights to indicate the volume of outgoing and
incoming wireless traffic (frequency), whether one is connected to
anything other than a local mesh (pattern within a given frequency),
and the proximity of Bono (flicker/stutter/'electrical fainting'
within a given pattern).

What would YOU like to see those lights do?

Hi Martin,

Thanks for testing!

 Implode-4
 - works well an 3 XOs tried!
 - The first (easy?) puzzle is not one you can use so it's fairly
 confusing.
 - Loading a large puzzle is also quite slow. (Is it trying to compute
 whether it's winnable?)

Yes, Implode tries to only create solvable boards; the time taken depends
somewhat on the random number generator and increases with the size of the
puzzle.

I'm not sure what is meant by the first puzzle is not one you can use...
If you mean that the puzzle is not solvable, that shouldn't happen, and
should be considered a bug if it did.  But I have not yet encountered such a
board; in my experience every puzzle that initially appears unsolvable
turned out to be solvable when I undid a few moves and tried again.  Or did
you mean that easy is not easy enough?

Thanks,
-- Joe

8.2-759 impressions

2008-09-06 Thread Douglas Ridgway
I spent a few minutes updating to 8.2-759 and trying things out, and
typed up a few impressions. I haven't investigated anything anywhere
near thoroughly enough to file any issues, but I hope this report is
useful anyway.

Hardware: G1G1 previously upgraded to 703

The update process went okay. There were a few weird errors I didn't
record during the update itself, but it seemed to work anyway. I
updated Activities on first boot as requested. The new updater is
nice. I'd previously had trouble updating the Browse activity from
inside of Browse itself.

General performance (boot and activity launch times) seems improved.

Networking: no longer needs to be told which AP to use, very nice.

Power management: seems much better. I closed it and left it on
unplugged overnight, and was surprised to see a full charge in
morning. From previous experience I'd expected total depletion.

Sugar shell
 I generally like the new interface, especially config.
 Glitches include the appearance of a frame which couldn't be made to
go away without a reboot (condition occurred multiple times), and
duplicate menu items in frame top bar activity hover menus.
 Clicking an already started activity seems to open new instance,
instead of switching to existing one, which is what I would have
expected.
  The task switching (Alt-Tab) interface improved, and Alt-Backtab now
works, happily.

Browse works. Things I tried:
 general web/news:  wikipedia, salon, nyt: okay, but linked  mp3 for
an article failed: error message something like this movie requires
an MPEG layer 1 decoder which is not installed
  Phyla PDF from biology links on main browse page, after going
through rigamarole of download, look at journal, launch Reader – looks
okay though
 gmail is mostly usable, as is docs.google.com (incl doc export and
open in Write, and spreadsheet)
 wiki.laptop.org/go/Browse, youtube videos before Adobe Flash install:
viewing these pages froze system
  mylittlepony.com: didn't work even after Adobe Flash install

Record works. I took a still image, and a movie. Ctl-C after selecting
image doesn't copy to clipboard, I needed to use the hover menu.

Pippy
 I think simple easy text examples should be listed higher than fancy
graphics, they are easier for novice programmers to understand. I
believe it used to be this way?
 The examples I tried all worked except for the camera example
(illegal instruction).

Speak, StoryBuilder, and SimCity: all work, but StoryBuilder seems to
be missing sound, and quitting SimCity doesn't seem to kill it.

Write
 Works well enough so that I wrote much of the first draft this review
in it.  I moved a doc to a usb drive, and opened it successfully in
OO.o, including formatting. This didn't work before, so this is a
major improvement. In particular, this can now be used to print. I
also tested bringing an image in. Ctl-V doesn't paste image from
clipboard, needed to drag and drop from frame. It did work, though.
Various glitches include:
 file reopened at different zoom level
 I lost work several times, not sure exactly how, maybe some
interaction with Journal, or Sugar task switching. I was taking notes
in Write while I tested other activities. I eventually gave up and
finished writing on another computer.

I also tried Terminal, TamTamJam, TurtleArt, Paint, Etoys, TuxPaint,
Analyze, and a self-developed camera activity briefly. They all seem
to work as well as before (though Paint was a bit laggy). But Measure,
TuxPaint, and LogViewer didn't launch, and SynthLab crashed after
awhile.

In summary, there are lots of exciting advances, and I hope the
glitches get sorted out.
