Re: [Server-devel] Server-devel Digest, Vol 81, Issue 23
Tony, I don't want to speak for the teachers in Nepal, but I think, Speaking as an educator, that more real data is better than the red light green light scenario you propose. I would be happy to participate in the design if that would be helpful. Gerald On Sun, Jan 12, 2014 at 11:13 AM, Tony Anderson tony_ander...@usa.netwrote: Hi, I am taking a simplistic approach to this problem. KA-Lite has a simple coach report which basically shows a table with a row for each registered student and a column for each activity. The cell is blank for no attempts, a light green for attempts which did not reach 'proficiency', and a dark green to show proficiency in that task. I think this is adequate for teachers, particularly if they can click on a cell to get more detail (e.g number of items completed, number of questions answered correctly, and so forth). Many of the sites I am supporting do not follow the one laptop per child model. In one case, the teachers pass out laptops without regard to who used it previously. In other cases, a set of laptops are used in more than one class. This means recording data against the laptop serial number is insufficient. The implementation strategy is to have the site provide a list of students (currently first and last name with the username as a concatenation of the two). The student logs in (By using the Journal activity, login is assured at boot time. After that, students must login as laptops are passed from class to class). A modification to activity.py adds id, start, stop, and outcome to the metadata. The id is the db id of the student (not the username). The outcome is a string - empty by default. A procedure 'write_outcome' added to activity.py, analogous to read_file and write_file enables a Sugar activity to add specific outcome information (either a string or a json with one of the keys: 'comment':''). The ds_backup.py is modified to save objects in the datastore to the school server (item by item, not rsync). A data collection script on the school server can go through the saved Journals adding this information to a database so that reports (such as the coach report) can be created on demand. Similar to KA Lite, the goal is to make information available to teachers on the progress of their students so that teachers can provide extra help and encouragement as appropriate. Currently, KA Lite does not provide feedback directly to the students but the main Khan Academy site has many examples of this (badges, points, etc.).

Thanks for the paper. While we did point out to Portfolio and Analyze Journal activities in our session at OLPC SF Summit in 2013, I didn't include it in the scope of the blog post. I'll go back and update it when I get a chance. Just to place all my cards on the table, as much as I hate to suggest we head down this route, I think we really need to instrument activities themselves (and build analyses of activity output) if we want to provide meaningful statistics about learning. We've done some of this with Turtle Blocks, even capturing the mistakes the learner makes along the way. We are lacking in decent visualizations of these data, however. I haven't had a chance to read the paper in depth (which I intend to do this afternoon), but how much of this approach would be shareable across activities? Or would the depth of analysis be on a per activity basis? If the latter, then I'd imagine it would be simpler for something like the Moon activity than the TurtleBlocks activity. Meanwhile, I remain convinced that the portfolio is our best tool. I think the approaches differ in scope and purpose. In the RFPs I've been involved in, the funding agencies and/or the decision makers either request or outright require dashboard style features to report frequency of use, time of day, and in some cases even GPS-based location in addition to theft-deterrence, remote provisioning, etc. The same goes for going back to an agency to get renewed funding or to raise funds for a new site expansion. In a way, the scope of the learner-teacher bubble is significantly different from that of the principal-minister of edu. One is driven by learning and pedagogy, while the other is driven by administration. Accordingly, the reports they want to see are also different. While the measurements from the Activity may be distilled into coarser indicators for the MoE, I think it is important to keep the entire scope in mind. Don't get me wrong: satisfying the needs of funders, administrators, etc. is important too. They have metrics that they value and we should gather those data too. My earlier post was just to suggest ultimately we need to consider the learner and how making learning visible can be of use. That theme seemed to be missing from the earlier discussion. I am mindful of the garbage in, garbage out problem. In building this pipeline (which is where my skills are) I hope that the data that goes into this pipeline is representative of what is measured at the child's end. I am glad that you and Claudia are the experts on that end :-) cheers, Sameer regards. -walter cheers, Sameer ___ Sugar-devel mailing list sugar-de...@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel -- Walter Bender Sugar Labs http://www.sugarlabs.org -- Walter Bender Sugar Labs http://www.sugarlabs.org ___ Sugar-devel

Some time ago, SL used 2nd ASLO node, but it used the same MySQL and files storage. There is the same need in ASLO on a school server in the field. But in my mind, trying to adapt ASLO/AMO to this scheme is an overkill. The real environments might assume lack of maintaining or restricted school servers (for example XO laptops in offline schools), i.e., Apache+MySQL+PHP+ASLO/AMO is a real misuse. In this regard, Sugar Network[1] was initiated a ~year ago, i.e., content sharing system (in contrast to ASLO, SN will provide non-software content like books or Journal objects). Sugar Network functionality is explicitly split into server side and client application(s). Server side is capable for running even on XO laptops (XO-1.5 is preferable) in pure offline case (e.g. one-teacher schools in Peru when people have only XO laptops) with further offline synchronization[2]. Clients might be any applications that use REStful API provided by Sugar Network node (master server like ASLO or any distributed node). For now there are two clients[3] written as a lightweight Web application and one that is pure JS application. The centralized scheme (like ASLO) is available right now[3] (it is being assumed to be used in Peruvian pilot). The offline model is in progress and should be ready, in some stage, during this year.

Re: [Server-devel] Hidden SSID and Proxy settings
Jerry, The one I set up for testing has no security. The real one in the school has security. Clearly, this method (either one -- GNOME or NetworkManager) works. The issue is the persistence. To ask teachers to do this with 100 students every time they want to access the internet makes either one unworkable. Any help will be appreciated. Thanks.

After reboot, NetworkManager is restarted, and therefore no longer knows about the hidden network connection request. Agreed, I'll look for how Connect to Hidden Wireless network runs its re-scan for the hidden network in the code. The ONBOOT setting doesn't appear to work either. On an un-hidden network it does, or at least loaded as the UI becomes usable. Gerald, does your AP have any security or is it just hidden?

That way you don't have to fool with keys all the time. Since my XSs are exposed to the internet, I do run ssh on a non-standard port, which keeps out the script kiddies. If you're worried about that, it's really simple to change the port. Anyway, it's just a config file edit to allow password based ssh logins. As root, create a regular user on the XS. adduser gerald passwd gerald You'll be prompted for the new password. That's it for setting up a user. Enable password authentication in /etc/ssh/sshd_config and /etc/ssh/ sshd_config.in I think you're supposed to be able to edit only sshd_config and then run make -f /etc/xs-config.make sshd_config to do up sshd_config.in properly, but I just go ahead and make this minor change to both files, as I've never gotten xs-config.make to work consistently for me. In both those files, uncomment PasswordAuthentication yes and comment out PasswordAuthentication no so it looks like this: # To disable tunneled clear text passwords, change to no here! PasswordAuthentication yes #PermitEmptyPasswords no #PasswordAuthentication no Restart the ssh service. service sshd restart Now from an XO connected to the XS, you can ssh ger...@172.18.0.1 or ssh gerald@XS's hostname Enter in your password and you should be greeted with the motd!

Hello all. As our 5th graders are doing more and more work with their XOs, their being able to turn in and share their work products (as opposed to collaborating with others) is becoming more and more important. My temporary solution is having them upload their work (along with reflections, if desired) to Moodle, which I can do because we have an XS implementation. However, this means that if a student has created a Memorize vocabulary game that s/he want to share s/he has to: 1. Create the game. 2. Save it to the Journal 3. Go to Browse 4. Navigate to Moodle 5. Find the right course/right assignment within the course 6. Upload game. S/he pretty much has to do the same thing to download and then play other games. This is certainly workable, but dramatically slows down the momentum of creating games and wanting others to play them. So, I am asking to create/offering to help create an Activity that allows users to share work products easily. I know that Bert was working on something called Distribute, which may be a starting place. It seems to share Journal objects, which seems right. I am happy to work with developers on this.

Hi, I checked the apache config and added the mime type for the .pr
files. I downloaded the file on my Mac and it got the correct mime type and
offered to open the project in Squeak.
I'm not sure if the filename doesn't play a role on the Mac.
I tried on soas-strawberry and XO-802 and it did not open etoys from the
journal. Maybe etoys is looking for a different mime-type than
x-application/squeak-project?
Try application/x-squeak-project not x-application/...
It used to work on 802. And it does work in F11_XO1.5/Sugar 0.84 - I just
tried. Just go to Squeakland.org and click the project thumbnail next to
Jeopardy 3point0 which is the current project of the week.
Ok, good news! That opens in the etoys plugin in my browser so I will try
to change the mime type and test again. Thanks
Dave
Ah well, the plugin embedding code (on Mac/Win/non-sugar Linux) provides
its own mime type, so this does not really mean it will work in Sugar, where
you do not have (nor need) the plugin.
OK, I fixed this by adding
'pr' = array ('type'='application/x-squeak-project','icon'='video.gif'),
to lib/filelib.php in moodle. Looks like our version of XS did not support
this mime type for forum uploads in moodle. This should be an XS 0.6
install.
Thanks!

PASS - When a person switched away from an activity (as opposed to exiting it) this was reflected in the neighbourhood view. Spot check around room to confirm. 6. FAIL - Simulate dead battery - but cold shutting off a machine. Neighbourhood did not reflect this, showed they were still online. Had to restart, connect back to school server and shutdown properly to leave neighbourhood view. They way some of the kids are out in the deployment, they are still learning the whole shutdown/exit activity procedure, so this could pose a problem - though I understand how this could be hard to implement. 7. FAIL - a reboot (full restart or ctrl-alt-erase) causes the rebooted machines not to accurately reflect who is part of a shared activity. Some rebooted machines reflected a more accurate picture than others, but none had the full picture. Kids will be going offline and online all the time in deployments so I can see how this could become a problem. Though this will be somewhat tempered by the ability to still share and view other XOs.

Re: [Server-devel] DNS/dhcp question
Jerry, I am not trying to be vague about anything. I would love to give you a sense of what is happening. I want to apologize ahead for not being clear. Not all of this makes perfect sense to me. Current situation: My XS box has 2 NICS Eth0 connects to the school internet and has a static IP address (10.125.105.153; subnet 255.255.248.0) Eth1 connects to a VLAN set up for the XOs. The Access Points for the VLAN point toward the XS box as the DHCP server (so I'm told). I was given that IP address by my tech guy. Here are the parameters: -IP range is 10.125.140.0 -Give the SchoolServer an IP address of 10.125.140.31, -set up DHCP for a range of 10.125.140.100 - 254. -Subnet mask should be 255.255.248.0 Ongoing questions: 1. I have been working under the assumption that eth1 should have the Schoolserver address above (10.124.140.31). Is that correct? 2. What do I need to do (if anything) to configure the DHCP functions of the XS? 3. Is there anything else you need to help with this. Thanks.

If so, how should eth1 be configured? As long as the access point is in bridging mode there should be no issues, and nothing needs to be changed with eth1. Are you able to re-configure the AP if needed? If so, what ip address does the AP use for management? I only know what you tell me about your network layout, with your XS setup like that, what are the results of ip route ls? I'll assume that eth0 has a static ip address.

The AP are directing the dhcp requests to 10.125.140.31, a bridge would just forward the traffic, and not direct it. The default layout doesn't provide for VLANs, but adding an ip alias to eth1 should be no problem. create an /etc/sysconfig/network-scripts/ifcfg-lanbond0:3 containing: DEVICE=lanbond0:3 ONBOOT=yes IPADDR=10.125.140.31 NETMASK=255.255.248.0 BOOTPROTO=static IPV6INIT=no restart the network, you should see the alias with ifconfig..

[Server-devel] XS Timeout issue (maybe)
Hello, I have been testing an XS. We are in NY and the server is in Boston. I have set the Mesh Server on the XOs (in the Control Panel) for the server's URL, and edited /etc/hosts on the XOs to point toward the server's IP address. The devices connect just fine, and I can collaborate on activities between some machines. I am noticing the following things: 1. In the Neighborhood view on the XOs, different devices seem to drop off at irregular intervals. I don't understand why this is happening. 2. Even after a device has been shut down, it still appears in the Neighborhood view on the other devices until they are restarted. 3. I don't' see all the devices in the Neighborhood view at any one time. All of this seems different that how I understand how XS is supposed to work. So, some questions: 1. Is there some timeout function on the server? If so, can it be customized? 2. Is there any limit to the number of connections made to an XS from one IP address? I am thinking that since these devices are all coming from my school, they are all leaving the building with one IP address. 3. If there is such a limit, can anything be done about this? Thanks. My plan is to deploy 150 machines in the next two weeks, so any help will be greatly appreciated.

By default, eth0 should be connected to the outside world/internet. Eth1 will set itself up (with no help from me) as the DNS and DHCP server. Therefore, the XOs talk to the AP which talk to the XS which assigns IP addresses to the XOs. Is that right? Thanks.

You haven't said how the XS and AP connect to each other, but I'm assuming it is via ethernet, that is the AP is not directly attached via USB. If that is the case the XS needs two ethernet cards, one for the AP and XOs, and another for the world. In all likelihood these would attach to different VLANs. I have fiddled with manually configuring ethernet on the XS and have wasted a lot of time. If I were in your situation, I would simply reinstall the latest version of XS, especially since it is suited to your architecture and you probably don't have anything at this point that you need to preserve. Ask your network guy for a static IP address and addresses of the DNS server and gateway for the world. During the install use these values to set up eth0. Attach this ethernet port to the VLAN that includes external access (not the XOs and AP). XS install will set up eth1 with the proper IP address along with DHCP, DNS, Gateway for the XOs. Attach this ethernet port to the special VLAN created for XOs and attach the AP to the same VLAN. If the AP has a static IP address it needs to be in the subnet of eth1 and not in the range of DHCP address supplied by the XS, though letting the AP get its IP address via DHCP from the XS may also work. Eth1 addresses will probably start 172.18. It is also possible that what you think are eth0 and eth1 are reversed by the install and there is a command to switch them, but a little experimenting will also reveal what's what. My guess is that you had the XOs in the same VLAN as the XS's external port before, which is why ping worked, but nothing else.

Re: [Server-devel] XS Help, please
Martin, I will look at the configuration section as you suggest. I have been using it. Are you saying that without doing anything else (like editing dhcpd.conf), the server will act as the DHCP server? Or do I still need to edit that file? Also, do I need 2 NICs. My network guy says no. That if I set the default gateway properly, all will be well. What do you think? Thanks again.

Re: [Server-devel] XS Help, please
Tim, This is incredibly helpful. I will get and install the 2nd NIC, and then reinstall the XS software. I will give all this a try when school resumes on Monday and update the list. Thanks.

Re: [Server-devel] IRC channel/using ejabberdctl
I am having a similar problem. There seems to be a discrepancy between the host/domain names between the server and ejabberd. I would really appreciate clarification of the conventions for this. Thanks. Gerald 2009/2/18 Yifan yifan@students.olin.edu Hi Martin, I went into the log files and realized that the domain had a schoolserver tacked in front of my domain name, which solved the previous problem; apparently I was trying to create an account for a server that didn't really exist. The specific domain name I was trying to use was olpcnetworkserver.cfs.mass.org, but I think it's now schoolserver.olpcnetworkserver.cfs.mass.org. I'm now running into another problem in this step. Now I'm using ejabberdctl register admin schoolserver.olpcnetworkserver.cfs.mass.orgadmin and getting the error RPC failed on the node ejabb...@e1534: nodedown I also attached the log file.
