KahnLite

[GoogleCodeExporter]

Hi Michael,

thank you. great work plan. I agree that it is fine to let KALite handle all 
that it needs itself (e.g. downloads).

On the licence side:
KALite is BY-NC-SA, so it fits well with awarenet. We have to say that this is 
KALite in the background, and make our software freely downloadable to others 
if it is tightly integrated with KALite. We cannot charge money for the 
software.

Looking forward to the progress report.
Best, Ron

KA Lite is integrated into Awarenet and needs testing. Tests seem to start next 
week.

It is probably best if tests be done on mothsorchid.com (our test network) 
instead of laptops and other servers. Will let you know once KA Lite 
integration is available there.

[GoogleCodeExporter]

Please, get in contact with Terri, Antje and Rieke, once it's available on 
mothsorchid and let them test it on mothsorchid. 

It would be good if you do not explain too much, so that we will also get 
feedback on usability.

At the same time, it would be necessary to also remind them quickly how Google 
Code works, so that they can create issues there instead of sending emails or 
similar. I have given all of them an introduction, but reminders are good. Do 
you think you can do that?

Michael, is KhanLite tested well enough that it can be played on mothsorchid on 
Monday, when Strix finished the move?
After uploading and testing it again on mothsorchid, it will have to be put on 
awarenet.eu for SciFest. Are you confident that we will manage that? 

(Sorry that I have not been part of the testing. Ron gave his best to install 
awarenet and KaLite on my laptop, but still hasn't been able to finish it off. 
Different story with Mac.....)

[GoogleCodeExporter]

I hope that it is tested well enough, I think so, functionality is quite 
limited. We shall see about uploading it unto Mothsorchid or awarenet.eu, 
because there are system dependencies that need to be satisfied and I am almost 
certain that I might not have enough system privileges to do the 
installing/changes.

It is probably most desirable and I would recommend that Strix will do the 
KaLite installation onto Mothsorchid and awarenet.eu. Whe shall see how he 
fares with the upgrades/updates ...

Would it not be best if you would get a cheapish laptop for the Berlin 
operations in order to be able to test there with your own installation? Are 
there many schools that are customers of us that make use of Macs? I hope that 
Mediamarkt has a good deal for you soon ...?

Original comment by appiapp...@gmail.com on 7 Mar 2014 at 11:36

[GoogleCodeExporter]

Ok, I hope that Strix will have time for that. It is not very trustworthy to 
present something at a conference that does not work when the people want to 
use it from home or their school afterwards. 

The VSA and eKhaya ICT have absolutely no money to buy any additional 
equipment. Personally, I wish I had the money to buy any electronic equipment, 
but I don't.

I am busy reorganising code according to new handling structure (do404/redirect 
to action) and at the same time am trying to figure out what changed with 
regards to login. 

The problem seems to be that for some reason the user does not stay logged in 
for long, which requires that the code has to automatically login in the 
background again.

Original comment by appiapp...@gmail.com on 18 Mar 2014 at 3:50

[GoogleCodeExporter]

I will get in touch with KA-Lite project and tell them about us. IMHO It is in 
their interest to have us interfacing with their software and they will be glad 
about the collaboration.  Some communication could help with such problems.

Original comment by Ooskapenaar@gmail.com on 18 Mar 2014 at 9:48

[GoogleCodeExporter]

I managed to consolidate the automatic login again. The reason for it to be 
unstable was not a change within KhanLite API it rather was a misunderstanding 
on my side about how Sessions and Cookies work, which came to the forth with 
this new code structure.

I will now continue moving KhanLite integration functionality into the new code 
structure.

I am still having strange occurrences of the system signing out on me and the

Google Chrome seems to make use of downloading the video in ranges while

it right away.

Original comment by appiapp...@gmail.com on 15 Apr 2014 at 2:34

Bottle neck with Google Chrome seems to be identified. It lies with the single 
threaded nature of the 404 event handling when part of a video file is 
downloaded. All the other calls have to wait until this call is completed.

Original comment by appiapp...@gmail.com on 16 Apr 2014 at 10:36

[GoogleCodeExporter]

Antje and Riekes test report indicate that there might be an issue with how 
points are recorded for students. But it might also be that the video playing 
issue prevents point messages/calls to get to the kalite system in time to get 
recorded properly.

I will write a test guide that tries to identify the issue with the points once 
the video play issue is solved.

I tested Kalite on mothsorchid quite often in the last few weeks and got a few 
bugs. 
Especially today, I got an error message and couldn't test Kalite at all.

Most of the inconsistencies happen because of slow internet connection from GHT 
office to mothsorchid.com . Certain messages to update points for example are 
not getting through in time, cancelling a download will often not work because 
the command arrives at mothsorchid.com only after the video has been downloaded.

Kalite integration is not working today because Kalite server is for some 
reason not started anymore. I am looking into how best the integration could 
react to this.

thank you Strix!

I will show a different entrance sceen into Kalite implementation if server
is not available.

It will say something like "Kalite Server not started, please contact your
Awarenet Server Administrator."

Is that ok?

Original comment by appiapp...@gmail.com on 26 May 2014 at 10:58

[GoogleCodeExporter]

I inserted the check.

The Kalite integration menu is now not shown if the Kalite server is not 
responding. Instead you will see a message telling you "Cannot access Kalite 
Server, please ask your awarenet Administrator what the problem might be!"

With this, the user cannot stumble into any problems and knows beforehand that 
Kalite will not work.

Maybe Rieke can ask Stryx to stop kalite server on mothsorchid and test this 
case?

Original comment by appiapp...@gmail.com on 26 May 2014 at 2:31

Strix stopped the kalite server on mothsorchid for a few minutes and I tested 
this case. Everything worked out perfectly and I could see the message.

Original comment by rieke.he...@gmail.com on 26 May 2014 at 2:45

[GoogleCodeExporter]

Thank you for this fast track testing!

Testing this on Mothsorchid from Grahamstown has its limits due to the 
fluctuations of the internet service (often slow speeds resulting in time outs 
and lost or very late packages). I think we tested what we could test and the 
bugs we witness are very likely results of this fluctuating internet service 
(by the way my access at Charles street is not much better). So it would be 
good if we could test on Mothsorchid from a more stable and high speed internet 
environment, like from Berlin? The test guide can be downloaded a few comments 
earlier ...

Tests seem to be inconclusive and not satisfactory. I recommend to not upload 
Kalite to awarenet.eu and to not flag this as done. I will as a 3rd parallel 
task continue testing this. 

What has to be established is if the bugs we see are purely Kalite bugs or if I 
introduced the bugs with the functionality redirection that we have to do 
(request to awarenet and awarenet requests in-turn from Kalite).

I will do the tests on mothsorchid as soon as Internet has improved over here 
(neither Charles Street nor Office have acceptable speeds and stability at the 
moment). I have Telkom coming to Charles Street for the xth time in order to 
fix my connection ... so my tests might happen hopefully within the next few 
days (Telkom has announced their coming tomorrow again).

Internet seems to be restored at Charles Street and this means that I can test 
Kalite on Mothsorchid properly. I need to first test Kalite directlly on 
Mothsorchid (port 8008) and then test the Kalite functionality through awarenet 
(port 8000) and see if and what the differences are. I will start testing this 
afternoon.

Spent time to test Kalite server directly on mothsorchid. Cannot test 
awarenet's Kalite on mothsorchid at the moment due to DNS issues. Have to wait 
until DNS issue is sorted out so that I can establish if there are differences 
between the two.

Original comment by appiapp...@gmail.com on 18 Jun 2014 at 2:37

[GoogleCodeExporter]

I tested "Kalite known issues" on my laptop and as local as this, all works 
well, to the point so to speak. Subtitles also work perfectly.

The valid use case of it is running it on a school network and see how it 
behaves there. I suspect that it will work well. Accessing/testing it through 
Mothsorchid and awarenet.eu will sometimes lead to problems and I suspect that 
the culprit is the Internet Connection with its lag/latency/lost packages/slow 
connection issues. 

My recommendation is to put this issue now to rest, let it run at a school and 
see if any issues arise there, I expect very little, close to none issues. 

Work still to be done is to move Kalite code out of the lessons package into 
its own package and at some stage we might address the multi/school 
installation problems if we need to - as it is at the moment Kalite should only 
be used for a single school set-up as the student data are all stored into the 
same database location/region. The result of this is that any student's data 
can be accessed by any teacher, even those that do not teach at the school the 
student is educated at (again this only applies to multi/school set-ups as for 
example awarenet.eu)! 

Original comment by appiapp...@gmail.com on 30 Jun 2014 at 11:37

If agreed, I would need to update Kalite on awarenet.eu to have it working the 
same way mothsorchid works.

Original comment by appiapp...@gmail.com on 30 Jun 2014 at 11:38

[GoogleCodeExporter]

This sounds great and very promising to be working at the schools, indeed. 
Please, update KaLite on awarenet.eu as well. 
At the moment, I am not worried that teachers have access to schools other than 
their own. After Festival, I will ask Antje and Rieke to test KaLite with one 
group only, perhaps we can approach a science group in the Joza Youth Hub as a 
pilot group. If problems arise, we can open new issues. 
Once, the multi school setup works 
(https://code.google.com/p/awarenet/issues/detail?id=387), awarenet might 
become more attractive again for KW, which could then be a good time to 
approach them again, but it's ok to give it some time.
Once, KaLite is updated on awarenet.eu, this issue can be closed. Thank you!

I uploaded code to awarenet.eu. Kalite Server is not active/running there at

Unbelievable, but the tests I specified where not covering all the cases and so 
was it possible that a bug crawled all the way to awarenet.eu!

The bug is that the exercise map in watch&exercise does not work at all.

These were the bad news, the good news are that I managed to find the culprit 
Kalite code that caused this bug and it is now corrected. Exercise map works 
therefore again. Please look at it on mothsorchid and awarenet.eu.

I will mark this issue as fixed as soon as somebody tested it on the two 
servers and confirms that it works.
