Re: I'm down in Uruguay this Xmas.
Hi Richard, I was in Montevideo last week, tried to connect with some (former?) Ceibal folks I know, and also got no meaningful responses whatsoever. So I'm not sure whether everyone is in a mad end-of-year crunch period (as the souther hemisphere school year is about to end), most people I know simply don't work there anymore or I simply was out of luck. If I had had more time (I was in Montevideo for only 24 hours) I would have tried to reach out to RAP Ceibal and ceibalJAM folks to see whether they can put me in touch with the right people inside LATU. However it's my understanding that many of the communities around Plan Ceibal are no longer active and/or dissolved so don't get your hopes up too much. Good luck and I hope it still works out for you. For me it was certainly fun to see a kid using an XO while his father walked him home from school somewhere in downtown Montevideo. :-) Cheers, Christoph Am 09.12.2015 22:44 schrieb "Richard A.

Confusion regarding 13.1.0 / 13.2.0
Hey everyone, after seeing the 13.2.0 build 2 discussions this morning I'm a bit confused. Has 13.1.0 been declared stable and released yet? For all XO models? If so, then the Software box in the top-right corner of w.l.o is outdated. (If I were to fix it, is it kosher to add the XO-4 there?) If no, what is the status and timeline for a final release of 13.1.0? Apologies if these questions have been answered already but I couldn't find any clarifications on w.l.o or in the mailing list archives. Aside of a general curiosity I'm also interested in this as we (as in OLPC Austria) are participating in several events in the coming weeks where we want to show off the latest and greatest and hopefully also attract some new volunteers.

"Page Fault" message on XO-1 and another Fix Clock question
Hey everyone, (1) on Friday while looking at one of the XO-1s which didn't show anything on the display (even with a display which was known to work) with the serial adapter I saw the attached output. Looking at the wiki now and given the number of "invalid system date" issues we saw on other machines I assume this is a case of the "page fault" message situation described on http://wiki.laptop.org/go/Fix_Clock#If_the_screen_does_not_turn_on. Or are there any other issues which could produce such an output? (2) Mike sent me a bunch of ML 1220 batteries as replacements for the XO-1 units which showed the "invalid system date" messages. However even with the new batteries in-place, after verifying that the (old) battery holders looked okay and having set the current time on the command-line the system date reverted back to 2000-01-01 00:00:00 after every reboot (and hence the "invalid system date" message kept coming up again). Any suggestions on what to do in such a situation?

Based on Plan Ceibal's error description I had extrapolated a similar approach and so it's good to hear that I wasn't totally off. Unfortunately I'm afraid that we simply won't have time to go through the 18 or so XO-1s which currently don't exhibit the problem during tomorrow's session. I will however pass along your instructions to some of the local tech-wizards and maybe they can do the workaround at some point in the near future.

Excellent, thanks a lot for the step-by-step instructions. If I arrive early enough tomorrow morning I'll give this a shot. Oh, and I've taken the liberty to copy-paste your instructions to http://wiki.laptop.org/go/Disassembly_top.

Re: Cameras not working on XO-1s
Hi again, this may sound like a stupid question but how would one go about swapping out the camera modules? I couldn't find any instructions on the wiki on how to actually remove the motherboard from the chassis (probably one of the few things I have never done on an XO so far). That step seems necessary in order to access the module because from the front the white plastic piece makes it barely possible to see the cable and push the connector in place with a small screwdriver.

Re: Solution for "Unimplemented package interface procedure" error on XO-1.5?
Hi everyone, apologies about the confusion wrt to my "it's easier comment". The main reason why I said that is because USB flash drives are popular and in short supply at the library and so I thought just doing a straight-forward copying on the laptop would be easier for me. Anyway, since I arrived early enough this morning I did have time to do the usual USB-based firmware update and then the upgrade to 12.1.0 worked like a charm. Thanks again for your support. My progress here would be quite a bit slower if I didn't have you guys as a remote backup and knowledge base.

Re: Cameras not working on XO-1s
James, Gary, Wad, thanks a lot for all your input and the information. We now checked all the XOs which showed these camera problems and all the connections seem to have been fine. So I assume that what we're seeing is really the cable failure which Wad mentioned. Unfortunately my Internet connection here at the library is so sporadic right now that I can't download the PDF attached to #10148 but I'll try it again later today. Not sure whether I have the time to still add tape to all the camera modules tomorrow but I'll see what I can do.

Cameras not working on XO-1s
Hi again, another issue we encountered during today's workshop session was that on 3~4 XO-1s the camera didn't work (all machines are running 12.1.0 with the associated firmware). The effect in Record is always the same: a grey still image. However when running the hardware self-test 2 of the machines passed the test even though the camera output on the display was total noise. With the other machine or two the self-test failed. Since I've never seen issues with the camera before I was wondering whether there was anything we could try beyond verifying that the camera connector is in place (as described at http://wiki.laptop.org/go/XO_Troubleshooting_AV#Errors_communicating_with_the_camera )?

Solution for "Unimplemented package interface procedure" error on XO-1.5?
Hey everyone, while updating a bunch of XO-1s and XO-1.5s from the Lubuto Library Project here in Zambia today we ran into an XO-1.5 which displayed the following messages upon trying to do a secure reflash 12.1.0: "Filesystem image found - Signature Valid Unimplemented package interface procedure" A quick search on w.l.o turned up this ticket from 2010 ( https://dev.laptop.org/ticket/10017). While it does say that the bug was fixed in subsequent versions it doesn't really provide a solution on what to do when the issue is encountered. Am I right in assuming that doing a separate upgrade of the firmware and then running the OS reflash again would address this? Or is there anything else I need to do?

Fwd: ETA for final 13.1.0 release?
Resent as devel@ is really a more appropriate place for my question. (Apologies for people receiving this twice!). Cheers, Christoph -- Forwarded message -- From: Christoph Derndorfer Date: Mon, Jan 21, 2013 at 2:22 PM Subject: ETA for final 13.1.0 release? To: Sugar Devel Cc: Mike Lee Hey Daniel and all, I was wondering whether you have an ETA for the final 13.1.0 release? The reason why I'm asking is that I'm heading to Zambia on Saturday evening to give a repair and maintenance workshop at the Lubuto Library Project which Mike has been supporting for a while. Since I'd like to get all their XOs up to 13.1.0 in preparation of Mike's education workshop later in February and local Internet connectivity will likely be limited it would be great if I could bring along the images for XO-1/1.5/1.75 on a USB drive.

You have received countless years of professional training, have ready access to the world's and the community's accumulated knowledge about using XOs and Sugar (thanks to the Internet), deal with student bodies who generally don't go hungry, have a pyhsic and social infrastructure that's available at very few Peruvian schools, etc. In short, I believe in the importance of crossing that invisible line and I have been lucky enough to see some glimpses of that happening in the past few years. However a significant number of pupils and teachers in Peru are miles and miles away from that line and will need other ways of support to even get them close to it. I also think it's odd to see how the role of the Internet and the connectivity it enables between people is apparently deemphasized in this conversation. I remember a time where Connectivity was one of the 5 principles of OLPC, and for good reasons I dare say. Due to the limitations of the Mesh network (and similarly so the newer ad-hoc networking options) and the lack of infrastructure components such as access points most pupils and teachers in Peru barely have access to local connectivity and all the affordances (incl. Sugar's collaboration features) and value it provides. Also I believe that people here will simply have to get used to bad news (whether fully justified or not) coming out of Peru. The project there still has potential but unless a lot of additional resources and brain power are invested into its overall value proposition and usefulness will always remain questionable at best.

Also, Neonode's press release refers to the touch-enabled device as "OLPC XO Touch 1.75" which fits in much better with the current naming scheme. Especially since an XO-4 which will pressumably become available before the XO 3.0 tablet sees the light of day would make the tablet seem outdated from day one.

Cjl,
thanks a lot for reminding us about the importance of localization:-)
Samy from France was kind enough to collect some links and information for
translation tools in another thread ("Open translation tools") and I hope to
have some time to look at them in some detail before I head to San
Francisco.
Maybe what we should try to do is try to compile some sort of good practice
guide for translation of documentation (as opposed to software itself) for
these types of events...
Cheers,
Christoph

Thoughts on Windows 8 UI / touchscreen UIs which could also apply to Sugar on tablets
Hi all, I stumbled across this article called "Why Windows 8 Is Fundamentally Flawed as a Response to the iPad" ( http://daringfireball.net/2011/06/windows_8_fundamentally_flawed). I think some of the things that are being said there could also apply to Sugar running on tablets and actually ties in very well with some of the related discussions I had with C. Scott and Bert in Uruguay. To me the key phrase in the article can be found in the last paragraph where it says: "Apple’s radical notion is that touchscreen personal computers should make severely different tradeoffs than traditional computers — and that you can’t design one system that does it all." Definitely some good food for thought in my opinion...

Any restrictions or recommendations regarding SD cards?
Hi all, the folks from the Austrian pilot project want to equip the XO-1s there with SD cards. Are there any restrictions wrt size, speed, etc. that they should be aware of when purchasing the SD cards? I'm particularly asking after reading James' mention of seeing more issues with newer cards and the XO-1 power off bug.

USB charging while XOs are switched off
Hi all, going through some of my notes from South America I stumbled across a question from a Peruvian teacher who had asked me whether future XOs would allow her to charger her mobile phone while the XO is turned off. Not sure where she had seen that but I think it combination with more and more mobile phones going to towards USB chargers this is actually quite an interesting idea.

Enhancing Sugar to support multiple users
Hi, I just created a new ticket (http://bugs.sugarlabs.org/ticket/2292) to get some discussions started on what changes need to be made to Sugar to work well in an environment where multiple users will work on the same machine (which is how Peru's next 300,000 XOs will be used: http://www.olpcnews.com/countries/peru/peru_between_one_laptop_per_child_and_seven_children_per_laptop.html ). Obviously this touches upon a lot of areas from simple naming of the machine, over the Journal, backups and probably a whole host of other issues that I haven't though of yet. (Additionally it also ties in to the ongoing "reorganise home menu discussion": http://bugs.sugarlabs.org/ticket/1206;-) Cheers, Christoph -- Christoph Derndorfer co-editor, olpcnews url: www.olpcnews.com e-mail: christ...@olpcnews.com ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Even more so I think it's a very clear symptom of the much-discussed disconnect between developers and end-users in the OLPC and Sugar Labs context. The core here is that software developers seem very reluctant to step out of their own comfort zone when it comes to processes and tools (a.k.a. point 3 a.k.a. "my way or the highway") yet consistently expect teachers and other XO and Sugar users to do exactly that. This leads to the current situation in which crucial information and feedback from these users does not make it back to developers and the broader community. Therefore rather than working on things that users need or need to work reliably (e.g. the Journal) resources are spent elsewhere. But that's all just basically a recap of the IRC discussion on #sugar earlier in the week and many hours of discussions with Bernie and others in Paraguay over the past 2 weeks. Now at this point I'd normally stop but seeing that I've been increasingly frustrated about this and have subsequently complained a lot about it I'll get off my ass and try something to improve the situation a bit. Over the next 6 weeks (can't make promises beyond that since university and my job will then start again) I plan to: (a) Contact people at deployments asking for their input as to whether they see a need for a closer feedback-loop between deployments and development (because maybe I'm seeing issues when in fact there are none). For this I'll rely on the people I know plus the contacts listed at http://wiki.sugarlabs.org/go/Deployment_Team/Places for starters but please send along any suggestions on who else to get in touch with. (b) If it turns out to be a need then ask for input as to how these needs could be best communicated so we can figure out an appropriate process. (c) Try to schedule some sort of meeting with several deployments, possibly as a continuation of the Sugar Labs deployment meetings on IRC or via a Skype call or something. In my mind the focus here should be input into what deployments would like to see development focus (more) on. (d) Compile all the resulting input into a readable format and distribute it where seen appropriate. Things I most likely won't do as part of these efforts include (but aren't necessarily limited to) setting up new mailman-lists, creating a new category on w.l.o or w.s.o and following wiki talk-pages, asking for a trac instance, learning to use git send-email, switching to Mutt, booting into Ubuntu instead of Windows 7, etc. ;-) As always, let me know what you think.

Additionally I'd accompany it with written guides with lots of photos which are great for printing out and bringing along when you're in the field or simply offline. Compiling a list of required equipment for these repairs might also be useful.

Re: [Sugar-devel] unable to share Activities on XO-1.5
Out of cursiosity: Has anyone done real and actual testing of collaboration on XO-1.5s with the/a current operating system version? Particularly testing that goes beyond 2 or 3 XO-1.5s... I was certainly very surprised to hear about the issues that Adam and the rest of the DC Book Sprint team encountered when trying to take these screenshots for the "collaboration" section of the guide. Last but not least: Can we expect collaboration between XO-1s with 802 and XO-1.5s with whatever OS it will be shipped with to generally work? Or are there any major differences in the collaboration stack inbetween those two versions that could cause issues?

Mmm, and after about 10min of use now I'm seeing a really weird issue where
the detail view of the Journal entry is simply one big gray canvas with only
the toolbar icons and the back button being available. Additionally on the
main list view I can't get any popup menus (to copy/send Journal entries,
etc.) anymore. FWIW datastore.log is filled with entries looking like this
one:

Someone had mentioned that the first person to access an update triggers some sort of procedure on the server but I wouldn't expect it to take that long.

On my Windows Vista setup the screensaver actually starts a couple of seconds before the session is locked so moving the mouse within that short interval keeps me from having to re-enter a password. So in that case I think that having two different intervals makes sense. However in the case of the XOs with basically instant resume I don't really see the advantage of distracting a user by reducing the backlight (which, from what little I understand about human attention, will indeed distract users from the actual content of the screen). The advantages in terms of energy use must surely be tiny given that we're talking about 5sec of reducing consumption by maybe 0.5W. On the other hand turning off the backlight completely after a certain amount of time as a first measure to reduce power consumption strikes me as an interesting alternative to the current implementation...

The automatic suspend takes out the WLAN. Just a quick first impression: The power-management kicks in as expected however to wake the XO up again you actually have to press the power-button, hitting a key or moving the cursor doesn't wake it up (as it does on the XO-1).

Power LED not switching to green even when fully charged
Hi all, I just noticed that even after a night of charging an XO-1.5 the power LED is still orange and hasn't switched to green (as it did with the XO-1 when the battery was fully charged). I know this is only a tiny detail but I was wondering whether this happens on purpose or if this might point to some low-level fault or something?

Re: XO-1.5 slow disk writes
Are Class 2 cards only used for these smaller batches of pre-production machines or will they also be shipped with the final mass-production hardware? Or is this a choice that countries/organizations will be able to make upon purchase?

Re: New F11 for XO-1.5 build 43
Hi all, I was wondering whether it was possible to upgrade the software on XO-1.5s without having to completely reflash the machine (which as I understand it is what fs-update does)? So basically I'd be looking for something similar to "olpc-update". Apologies if this question has been asked before but I couldn't find any info in the archives or w.l.o.

Information on XO-1 power efficiency
Hi all, I've been invited to give a short talk on "Energy consumption of Desktop and Notebook Computers" with a focus on the XO-1 design at a workshop in Stockholm next week. The audience will mainly consist of scientists and researchers working on IT topics within the context of energy consumption and climate change. Now while the original goal of getting the XO-1's power consumption down to 2W wasn't achieved it's still a pretty lean and efficient machine. I obviously plan to talk about the choice of hardware components and MLJ's display design. Another topic I'll touch upon is the wide-range voltage input which allows for a variety of power sources to be used without requiring further external regulation. One thing I'm less sure about is the DCON because I'm don't know how aggressively it is currently being used (maybe someone can shine a light on this, I didn't find anything about it on the wiki or the mailing list). Another question I'm interested in is what the efficiency of the AC-DC adapters shipped with the XO-1 is? I'm also wondering whether it makes sense to talk about some of the ideas discussed in the early stages of the project (e.g. suspend inbetween key-strokes which IIRC ended up not being implemented). As I said it's only a short talk (10min max.) but there's anything else significant when it comes to the power consumption and underlying design that I've left out above then please give me a shout.
