Re: connect to network?
I have found that a USB ethernet card works very well. Victor Hi, Another newbie question: is the machine supposed to be able to connect to an ordinary wireless network? It finds my router name (and indeed all the other networks alive locally), and asks for my WEP key (and subsequently shows it is on Canal 11), but that is as far as I get. ping doesn't work, and the browser activity cannot connect to the internet to find eternal websites. Please file a bug; this should work, and we're interested in chasing it down. Attaching your /var/log/messages file after an attempt would be most useful. We have problems with some types of encrypted APs. In the absence of a physical network port, this would be the only way I can copy files to/from the X0.

Re: Bridging eSpeak and Read activity
If we're going to go that far, why don't we make eSpeak a service, instead of an activity? The kid could select text anywhere - Read, Browse, Chat, etc - and select Speak text from the contextual menu. The highlighting is then provided by the child directly, and we gain the ability to span the entire system with this educational framework. It seems silly to put arbitrary ties between a few specific activities for something like this that has so much more potential. Ideally, this would go right next to the (hopefully forthcoming) dictionary and thesaurus. Heck, we can even add Wikipedia and Google links, if we want. Creating an environment which is able to respond to children's inquisitiveness would do a lot for the laptop as an educational tool. - Eben On 10/12/07, Hemant Goyal [EMAIL PROTECTED] wrote: Hi all, We are trying to Bridge the Read activity with eSpeak activity on XO.

Re: new user: no audio from speakers
Richard, If you do see the problem again, can you try to recall the order of activities. We have had problems in the past where one activity left the audio in an in-operable state for the next activity. Usually this is fixed by rebooting; but it is something to note. We believe that problem was fixed. Kim On 10/11/07, Richard Dobson [EMAIL PROTECTED] wrote: I have now updated to 616, and the speakers do indeed now work. Do I need to update the TRAC?

All activities should switch to a primary toolbar tab
Though this isn't in the guidelines formally yet, we are strongly recommending that activities switch to a primary tab when launched. For instance, Write should focus the Text toolbar; Paint should focus the Tools toolbar; Record should focus the Photo toolbar; etc. In other words, whatever you consider to be the base set of tools needed to dive in to your activity you should expose up front, eliminating the need for the kids to manually switch tabs before exploring your activities. There is an API for switching tabs (as tabs should also switch automatically according to context, when appropriate), which can be used to accomplish this goal. Thanks for taking the time to do this!

Re: Bugs and more
Kim, = Could you tell if you needed to reboot the AP and wait for it to settle and reboot the XO -- each just once, but you would have to do the order properly. It is my expectation that after setting up the AP, it would need to be rebooted. And it makes sense to me that the XO would need its file removed and then to be rebooted in order to 'see' it as a new AP. This should be in the release note. Here is what I *think* the release note should say (please make appropriate changes, etc and add it to the Kqrelease): If there is a change to the configuration of your infrastructure AP, then after making changes and rebooting the AP; please delete the network config file and reboot the XO. (you might want to put this in steps and say how to find the config file, etc) You are correct. First you delete the file, then you reboot. I updated it in the Kqrelease. = I believe Dan's comments on this is that it is probably just a UI bug and not affecting the functioning. If you agree with that, then you should put a note in the bug about your thoughts and re-assign it to 'Sugar' so the right person will look at it. I would let it remain as 'high' priority until we know more. Also, can you put a note in the release notes on this one. I agree, I also noted that in the bug. I rephrased it more clearly and forwarded it to sugar = This looks great, Yani. I have a couple of questions and I added a few notes. On the IP Addresses section, I don't believe that you get a 169.x.x.x address when connected to an Infrastructure AP. Normally you would get a real IP address given to you by the DHCP on the internet side of the infrastructure AP. Perhaps your AP (the airport extreme) was not connected to the internet when you did your testing. The ifconfig has 2 parts: msh0 and eth0 eth0 Link encap:Ethernet HWaddr 00:17:C4:03:31:FB inet addr:18.85.18.23 Bcast:18.85.19.255 Mask:255.255.254.0 ---this add is blank on mesh/link-local inet6 addr: 2001:4830:2446:ff00:217:c4ff:fe03:31fb/64 Scope:Globalnow it has a 18.85.x.x inet6 addr: fe80::217:c4ff:fe03:31fb/64 Scope:Link . msh0 Link encap:Ethernet HWaddr 00:17:C4:03:31:FB inet addr:169.254.7.84 Bcast:169.254.255.255 Mask:255.255.0.0 --this add is always belongs to the mesh inet6 addr: 2001:4830:2446:ff10:217:c4ff:fe03:31fb/64 Scope:Global it is either 169.254:local-link/MPP inet6 addr: fe80::217:c4ff:fe03:31fb/64 or 172.x.x for school server .. Also, even if the AP is not connected to the internet the above would not be unchanged. If you are referring to the Airport AP 18.85.x.x would be substituted by the IP given by 10.0.x.y, with or without internet connectivity. Also, I'm pretty sure you will not get a 192.x.x.x from the school server mesh. Usually you see 192.x.x.x from people setting up a home wireless network. So I made some changes to that section of your document. At the point the OLPC schoolserver operates at 172.x.x.x, but this is just a convention. The 172.x,192.168.x,10.x are equivalent private addresses and can be used with probability to another mesh somewhere else. I just conformed this with Michalis. You can also have 10.0. or 192.168.or even 172.x.x as an eth0 address when you connect to an AP, if it is configured so So, I am most confident these changes must be recovered. I'm not sure your DNS check info (resolve.conf) is correct for the case of 169.x.x.x. You say it is because the XO is connecting through an MPP. But I think you might get the same resolv.conf if the XO is 'hopping' from one XO to another to get to the School Server or to an access point. 'Hopping' is not the same as MPP. Since you don't mention anything about the scenario when one XO connects through another XO to get to an AP or to the school server... then I'm thinking there is one more case for you to explore. Or, maybe the case that you couldn't explain, where there is no dns resolution, but you do have a good IP and can ping by IP. Maybe that case if XO hopping. We can talk about it some more later today or next week. the resolv.conf is not related to hopping. I havent ever seen a 169 addrress as a dns, since we never have used an MPP, but I am pretty confident thats how it would work when connecting to one. When an XO acts as an MPP it creates a small DHCP server and stores locally the DHCP database. When you send a DHCP request you will receive a reply from the MPP with a 169.254address for you to use. The address of the MPP(which because of the mesh is 169.254 as well) will be your new DNS and DHCP server. Your info on the gabble service concerns me, specifically the part about it not being accurate. It would be good to spend some more time on this to document a broken case and write up the bug; add appropriate logs, etc. It is not going to be good if there is a local jabber server (on the school
Re: Bridging eSpeak and Read activity
Sounds groovy. I think there may be a way to provide an incremental multimodal language acquisition learning and life adventure/activity. LaLaLa? One of my favorite games is scrabble. We could call it squeak n spell if selchow and righter is not interested in making the world better. You can learn letters from scribble. If you already know x language, you can learn your own. Or, more fun, since children do not have preconceived notions about how you're only supposed to learn a single language, they can load up arabic, korean and chinese. They could play squeak and spell over the mesh with someone, and choose their favorite real or imagined language, or create new languages. They could hear human pronunciation, or gerbil for that matter (think alvin + chipmunks). For kids in different languages, machine translation is an option, and we're working on making it better (see meadan.org) scrabble is a perfect setting for a limited linguistic set, especially if squeak and spell is helping to provide that vocabulary and grammar. Squeak and spell could help children to learn and have fun, even if they were blind, deaf or mute. I would gladly place myself at the service of a developer keiretsu should something come to pass, whether it were squeak, python or treenimation, or a squeaking python slithering up a tree. -Original Message- From: Eben Eliason [EMAIL PROTECTED] Subj: Re: Bridging eSpeak and Read activity Date: Fri Oct 12, 2007 9:53 am Size: 1K To: Hemant Goyal [EMAIL PROTECTED] cc: Arjun Sarwal [EMAIL PROTECTED]; Devel@lists.laptop.org;Manusheel Gupta [EMAIL PROTECTED] If we're going to go that far, why don't we make eSpeak a service, instead of an activity?

something went wrong in the file system
Hello, My B4 with 616 build went into some interesting state. I was copying some executable files to a directory (under /usr/local/lib/) from my USB memory and playing with it (for several iteration) from the Sugar console. But I terminate the executable and left the system idle for a night. That was yesterday. Today, I was trying to remove the file I copied by rm command but get an error that says No space left on device. I try to reboot my machine (perhaps a bad idea) but it went into the launching X loop. I did force poweroff and now the unit doesn't boot. I got OFW's ok prompt and typed: dir nand:\boot but it says: jffs2-file-system jffs2:bad read I saw some trac items about nand corruption and it might have happened to me. I don't know if there is a way to salvage some useful information from my unit at this point, but if somebody has an idea (or just say it is a known problem) please let me know.

Aaron, Thanks! The irony is that I only did the sugar activity to showcase my algorithm, not to design a new neighborhood interface. Actual face pictures are another add-on I have in mind (we do have a camera available ;-)). Walter Bender also suggested customized XO icons that look bored, happy, sleepy... you get the idea. For the porting part, I would like to have the driver on ARM processor. I think it makes sense for portable devices to be able to communicate with XOs over the mesh.
