au196 on XO-1.5 summary (details below): * Music Painter problems reported previously are (now?) intermittent * Font in Terminal is still too big * Chat is very chatty on the network * ARP requests do not wake a laptop from suspend-resume * Regular “mdns” broadcasts keep waking laptops up
os29 on XO-1.75 summary (details below) * ARP requests do not wake a laptop from suspend-resume * Google Docs on Browse seems much more stable if suspend-resume is turned off Rachel did some work on the testing pages on http://wiki.laptop.org and we also tested Analyze_Journal and Sin diente (details below). Music painter v9 on XO-1.5s running build 196 for Australia. Found it intermittently does not work. Note that Ivy and Rosella are production XO-1.5s and Tank is a prototype. We tested on Rosella (firmware 22), Ivy (23) & Tank (22). On 3 iterations of shutdown, startup, start music paint as new, Music painter: * worked on Rosella twice * worked on Ivy twice * never worked on Tank Our n of 3 is not big enough to show that the failure rate of Tank is statistically different from the other 2. Record on Rosella - can take pictures and long movies at high res, did not test audio nor audio on movies Speak on Tank - don’t see any issue with the tool bar. Spirolaterals on Tank: seems to be working ok. Terminal on Tank: Font still too big? Physics on Tank: Still have the issue of when I draw lines that I see the cursor trail but does not construct a line - this is when there are no other objects there, so probably not a memory or buffer problem. Circle, square, motor all seem okay. Arithmetic on Tank: it is annoying that I have to wait for several seconds after I enter an answer and it tells me it is correct before it goes to the next question. Suggest the time restarts once the answer is labelled as correct. Tuxmath on Tank: tried to play but then realised my migraine is not letting me add :). Wake-On-LAN testing on XO-1.5 with au196. Three laptops on Adhoc Network 11, 2 with power saving turned on and 1 without, for the most part no other laptops on this network. We find that, when sleeping, the laptop does not respond to ARP requests, we allowed a laptop to go to sleep and we pinged it from another laptop, the first 15 pings were not sent due to no ARP information. It seems that a multicast packet woke up the target laptop which then received the ARP request. The following trace was made with tcpdump -p on the laptop that went to sleep: 22:06:56.270776 IP 169.254.6.176.mdns > 224.0.0.251.mdns: 0*- [0q] 3/0/0 (Cache flush) A 169.254.6.176, (Cache flush) SRV xo-a7-4c-2f.local.:5298 0 0, (Cache flush) AAAA fe80::217:c4ff:fea7:4c2f (129) 22:06:56.637739 IP 169.254.5.199.mdns > 224.0.0.251.mdns: 0 [1a] TXT (QM)? 39adda6e@xo-53-5b-82._presence._tcp.local.

If you join the network after chat is shared, chat does not show up in the neighbourhood. Chat sends a lot of network traffic, even when nothing is happening, there is a multicast UDP packet sent every 2 or 3 seconds. With two laptops in the chat these packets are 29 bytes long and seems to be some kind of clique message: 22:43:01.403803 IP 169.254.6.176.14986 > 239.255.71.127.14986: UDP, length 29 0x0000: 4500 0039 0000 4000 0111 9187 a9fe 06b0 E..9..@......... 0x0010: efff 477f 3a8a 3a8a 0025 ec0e 436c 6971 ..G.:.:..%..Cliq 0x0020: 7565 0103 fee3 cf85 02a6 c6dd f808 5e16 ue............^. 0x0030: eafe e3cf 856a bbc6 95 .....j... Joining a 3rd laptop to the chat causes all three laptops to send to the multicast address, and the packets are now 37 bytes long. This explains why suspend and resume is suppressed when Chat is running. This level of traffic seems excessive when nothing at all is happening in the application. We observed regular multicast “mdns” which caused the laptops to wake up. We didn’t make a note of how often this happens, but it might have been as often as every 45 seconds and was certainly more often than every 90 seconds. Google docs on Browse on os29 on XO-1.75 is much more stable if you turn off the power saving. We’ll explore this further, including on XO-1.5 next week. XO-1.75 prototype Bonnie visited a.sl.o using Browse - went to “just added” activities. The first activity in the list is one with no ‘activity name’ visible on the website next to the activity icon (when downloaded to the Journal it shows as Analyze_Journal) and the description says “This activity gives you the possibility to graphically, the journal usage”. I think it needs to say “... to graphically view the journal usage”. When opened you see a pie chart, which is really nice, but the labels are a bit too small to make it easy to read. There is some information to the right (info, total space, etc) but no corresponding numbers visible - it might be off the screen or just missing. I wondered how to check the accuracy of the pie chart for testing this activity. When you type df in terminal you see 76% of /dev/mcblk0p2 is used. I don’t know how to differentiate what part is the journal. There is also /dev/mcblk0p1 that says 20% used. https://plus.google.com/photos/118146064923365210751/albums/5468706263336090945/5718060299951849970?banner=pwa Sin diente activity on Bonnie Some of the examples in Animals topic said “my body is long” but answer is plural - serpientes. Quite like the trivia about the animal when you get the name right - however, there may be a better word for it than ‘significado’ (significance). Activity maintainer could consider changing to something like ‘Did you know?’ or similar. Strange phrasing on shark, ‘Y mi nombre doy a respetar’ - Do you mean ‘Y mi nombre genera respeto’ or something of the sort. Within four questions we started repeating. The answer for ‘Tengo escamas y vivo en el mar’ is ‘pescados’ - Pescados is the word for fish that have already been fished out of the water - those still living in the sea are called ‘pez’ (plural: peces) This is actually also what the ‘Significado says’ but - the correct answer to ‘vivo en el mar’ (present tense) should be peces. In the moral values section - the clue says ‘ cuando aceptas a los demas tal y como son) and the answer is ‘respeto.’ meaning that until the period was added to the end of the word it would not accept the answer was correct - should the period be considered a letter? Same for ‘confianza’. In the verbs category, a clue says ‘ Cuando estoy alegreme me gusta’. That does not sound like correct Spanish grammar :) We like what seems to be the ability to create questions oneself. This shows up in the tab labelled ‘modo versus’ which I am not sure is descriptive - I think the tabs are whacked - I think that pressing modo versus sends you to the destination that should be of ‘Agregar lista de palabras’ and pressing on ‘agregar lista de palabras’ seems to take you to the destination of ‘Categoria personalizada’. Pressing on ‘caetgoria personalizada’ takes you to a page that says: “no se ha imporatado ningna lista de palabras ...’ that has no way of returning to the game and then one needs to stop and restart the activity. I love the ‘countries’ topic. In paises, the clue ‘world champion in 2010” (yes, I know it is meant football, but being in New Zealand - land of the long rugby history - I’d suggest the sport be named!) the answer is España(with wiggly on the n) which the native English speaking player pointed out to the Spanish speaking player requires the player to know how to make ñ on the keyboard and not all olpc keyboards have this written on the keys. There is a learning curve here if the game is used to teach Spanish to others. The answer for ‘sirve para informar y los mayores lo leen’ (I suggest using the word adutos instead of mayores) - the answer is ‘el periodico’ which uses the ‘el’ at the beginning, which is not required in other answers. Overall, we liked the activity and enjoyed using it. The native English speaker is slowly learning the basics of Spanish. Rachel looked at the test pages on http://wiki.laptop.org/go/Tests after Tabitha discussed http://lists.laptop.org/pipermail/testing/2012-March/002629.html and started trying to clean up. She says: The current http://wiki.laptop.org/go/Tests page contains many subpages. These contain potentially useful information, although the long pages are hard to navigate. I have amalgamated all the Calculate tests under a new page: http://wiki.laptop.org/go/Tests/Activity/CalculateTests, and made a note on all the old pages that they are obsolete. If we agree this is a good strategy, I can delete the old calculate pages, and amalgamate the other test categories. Thanks testers
