I've got a Linksys WRT54GL using stock firmware and WPA 2.

There are no other XOs or XO-servers nearby.

I've seen up to 4 of my neighbors WiFi boxes.  Usually there are only one or 
two.


I've rebooted about a dozen times in the past few days.  It connected cleanly 
all but once.  That time, it connected after I poked Connect on the right 
blob.

Is there some place I can look for more info after it doesn't work?

No problem, was good fun too!

 Implode-4

 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 thought as much -

 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?

Well, I get a 3 block puzzle. Perhaps I don't understand the rules
completely, but clicking on the blocks didn't do anything interesting.
Other testers suggested I tried the larger games / blocksets and with
those I managed to get some implosions going, though I didn't manage
to solve one.

cheers,

Hi Martin,

 Well, I get a 3 block puzzle. Perhaps I don't understand the rules
 completely, but clicking on the blocks didn't do anything interesting.
 Other testers suggested I tried the larger games / blocksets and with
 those I managed to get some implosions going, though I didn't manage
 to solve one.

The way the game works, you can only remove blocks if they are in a
contiguous group of size *three or more*.  There are other score-based
games (like SameGnome) that allow you to remove blocks in groups as small
as one or two, but Implode is intended to emphasize logic over
accumulation of score, and the three-piece rule leads to puzzles that are
more obviously solvable.  I've tried to make the game discoverable by
only highlighting the removable groups as the mouse cursor passes over
them.

There should always be a series of removals that clears the board.  It
sounds like you might have tried unsuccessfully to remove groups of one or
two on the easy level and didn't try removing a larger group.  Is this the
case?  If so, does the game perhaps need some sort of tutorial or hint
mode?

If you actually encountered a puzzle where it didn't let you click on
*any* blocks on the board right after the board was generated, that would
be a bug.  The easy puzzles should be easily solvable -- even random
clicking on blocks works for many of them.

Thanks,
-- Joe

  - 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.

Alastair mentioned seeing something similar with his AP at home,
letting it time out or hitting cancel.

Someone with deep NM fu needs to exercise these codepaths and look at
WTF is in the state machine when it's happening...

Martin,

You used a old verison of Colors! The current version of Colors! is  
V4. I just
  fixed the http://wiki.laptop.org/go/Activities/Joyride activity  
group so if you
run software update again in the control panel you should get it.
(If not add the url to the activity groups for software updater).
It is a lot of fun to collaboratively paint with Colors!  Also  
Develop now points to Develop V35.

 As 8.2 is stabilising, and we read from Morgan's survey that not all
 activity authors are testing on 8.2, it seemed an interesting track to
 play with as many possible activities as we could on 8.2 .

 So we did :-) Adopt an activity today was the motto.

 Overall 8.2 is looking fairly good. Networking and sharing proved to
 be a challenge - see notes at the end.

 Couple of notes
  - most of these have no 'component' in trac, we filed them as
 other-activity, and added the name of the activity as a keyword
  - very hard to find the email addresses of the authors! how do we
 show love to them? why do we have in the wiki maintainer unknown for
 so many activities where the maintainer is well known?

 Wikipedia / Journal
  - Worked very well and it's fantastic to have the content on the XO.
 But installation of large activities shows UI problems with the
 Journal. The Journal UI locks up while copying and unzipping with no
 user feedback.

 Colors-3
 - Worked well
 -,Very high CPU usage even when we weren't painting, empty canvas.
 - Does not close (#8335) apparently due to a bad interaction withe the
 snapshot that Sugar takes when 'stop' is requested.

 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?)

 X2O-5
  - Worked very well
  - A bit slow sometimes

 Doom
  - worked well on 3 separate machines.
  -The key bindings however mask the Sugar keybindings. Bug...?

 Mini vMac
  - Works well, and gives the Mac fans little jumps
  - No sound?
  - No network?
  - Display is very small, could it be done with a 2x zoom?
  - Shutdown process is mildly awkward

 Conozco Uruguay
  - Fails to start #8334

 Frotz
 - works well - had fun playing it!

 PlayGo-3
  - launches and collaborates successfully,
  - the Activities page  in the Wiki only offers PlayGo-1 which doesn't
 work on 8.2! (Andrés has already fixed this, thanks!)

 Speak-7
  - Worked well
  - Can we teach it Spanish?

 Horsegame
  - works well! - you can indeed haz a pony
  - Carrots!
  - Apples!

 Asteroids
  - fails to start
  - No module named ImageLoad (#8333)

 FiftyTwo-2
  - launches and seems to offer collaboration, but this in practice
 does not work. The player always plays against the computer, even if
 the activity has been shared successfully.

 Abalone-080601
  - starts and works well.

 SliderPuzzle-5
  - successful launch
  - crashed on one XO (out of 2 tried) but we did not get a log of that
 (Alastair - do you think you can try to repro it and file a bug)

 JigsawPuzzle-3
  - successful launch and play

 Jump-1
  - successful launch and play

 Mimic-1
  - failed to launch, illegal instruction in mmxCombineAddU (#8336)
  - how to contact the maintainer...?

 Implode
  - successful play on two separate XOs

 Calculator
 - successful play
 - Does not display an error on divide by zero - even though it does
 display error msgs in some other instances
 - If fed a large calculation, it locks up trying to resolve it, UI is
 no longer responsive, does not respond to stop. (Grant, can you file
 a detailed bug on this?)

 Simcity
 - Successful play
 - Tiny fonts

 Maze
 - Successful play

 Sudoku
  - Successful play

 Notes on collaboration and networking

 Collaboration and networking...

  ...Oh so much trouble.

  - Collaboration over simple mesh mostly works.

  - 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.

  - Network manager is _not _ happy when an AP goes from WPA encryption
 to no encryption. iwlist can see the AP with no encryption but
 ccording to nm-tool, the AP is still requesting WEP. The fix:

 /etc/init.d/NetworkManager stop
 rm /home/olpc/.sugar/default/nm/networks.cfg
 *cold reboot* (does the Libertas driver preserve any state?)

  - Collaboration over unencrypted AP + Schoolserver running ejabberd
 did *not* work at all. I did not have a chance to debug this
 thoroughly, but odd things happen. olpc-netstatus errors out because
 session.info is missing. The client side never tries to register to
 ejabberd apparently. !?

 Credits... a ton of testing and debugging today, thanks to

  all those activity authors!
