Cannot see activities in joyride-2005
Hello, Yesterday night I did an olpc-update to joyride-2005. After rebooting the system, I no longer had any activities in the ring view. The list view showed a list of faded out activities from /home/olpc . Thinking that it was caused by some settings in /home/olpc, I tried moving /home/olpc aside and creating an empty /home/olpc. But then X11 wouldn't even start. Does someone have a clue of how to restore the activities? Thanks, Dov ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Need help creating .xo file
Hi All , I was wondering if you could help me out with this. I got the activity working fine on the OLPC. Now I want to create a .xo file for my activity so that I can install the activity on other XO's. My activity structure is as follows: -activity --has the .info file and the icon -bin -- has a shell script and the exe which i have to run -lib -- has the libs which my application is dependent on - MANIFEST file There is a shell script in the bin folder which I have included in the exec tag in activity.info. I created the activity bundle according to the information in the post http://olpcnews.com/forum/index.php?topic=1555.0 . I have named my .xo file name.activity.xo If I unzip the .xo in the Activities folder and then restart the X-server it gets installed and I get the icon in the activity tray. I tried installing it by copying the .xo to a thumb drive and then running sugar-install-bundle on the XO but it gave me a DBUS timeout error. I also tried to install it through the browse activity as given in http://wiki.laptop.org/go/Activities#Manual_installation and through the Journal without success. Can you figure out where I am going wrong?? Thanks Shivaprasad ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

The Bundle installs correctly only when I unzip it manually and then restart the X-server. I want to do this through sugar-install-bundle or through browse activity or through Journal. None of which seem to work. Anyway when I tried to install through the sugar-install-bundle command It failed giving a DBus timeout. Here are the log files I got.

Wikipedia activity - unstoppable... bug?
Hi Chris, here in Lima, I'm debugging a problem that the local team has shown me with the wilkipedia activity not starting for a second time. The problem is that the server never really closes, so the 2nd invocation finds the socket taken, and can't use it. Apparently this is a common issue with SimpleHTTPServer. We need to be able to close the server when the app closes. I am starting to work on this - but can't get on irc, fascist fw - so if you ahve anyhint, welcome :-) So far my plan is to - learn what signal/event we get from Sugar when the app is closed (do we get one?). I'm *so* not a Sugar developer ;-) - Try if a SIGHUP or SIGTERM will bring it down cleanly - if so, try and send one to the process on close - If signals are not the way, try the recipe at http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/336012 Ah, I see that there's a known bug and some recent patches for it: http://dev.laptop.org/git?p=projects/wikiserver;a=summary - do we know what version of the code is in Peru's 703-5 image? cheers, m -- [EMAIL PROTECTED] [EMAIL PROTECTED] -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: OLPC: Open Organized Transparent
What we've got here is a failure to communicate On Tue, May 27, 2008 at 7:38 PM, C. Scott Ananian [EMAIL PROTECTED] wrote: I'm sure I haven't said all the things you'd have liked me to say, but I've done my best to be open and honest here. Thank you for starting this discussion. Thank you for continuing it despite your priorities and time constraints. While much of what follows are direct responses to your email, please don't take it as directed personally. The original post was focused on what the OLPC could do to be more open, organized and transparent. I.e. to create a healthy community. As such the short comings I'm belaboring are with infrastructure, communication, and organization. Though in the end, it all comes down to individuals working together... or not. I'd much more interested in hearing a response to the issues I raised rather than potshots at the messenger... I hope you agree. Issues o how to address in the insider/outsider decisions made behind closed doors issue? o unbundling: hardware, os, drivers, and desktop metaphor o how to seed and grow the community o offer a reference solution embrace all solutions Well, since I'm apparently the one fingered as smart, holier than thou, and derisive, let me publicly apologize for being short-tempered at times. I do get frustrated when I see the same issues pop up over and over again: remember there are many many more of you out there than there are here at 1cc, and in order to be successful we at OLPC *must* allocate our time wisely. Sometimes that means I'm rather short and/or terse. I didn't intend to single you out. Your comments happened to be the easiest to find from an @laptop.org address. In catching up this morning, I noted at least 2 threads where someone was either calling for more professional behavior or a code of conduct. That said, you _are_ an OLPC employee. When I or someone outside the project is unprofessional... we're just lone volunteer assholes. Not to lecture... well yes, I am lecturing. But when you are short/terse it reflects badly on the project and the community atmosphere. Issues popping up again and again are a sign that issues, decisions, and their rational aren't documented well enough. Wiser time management would be to: o respond with a url to documentation (or write it then respond with a url) o ask if there is anything in the referenced documentation that needs to be clarified o ask where the person raising the question looked for their answers o update where the questioner looked first to reference the documentation You aren't bad on #1, but the others... A related issue is when people loudly insist that OLPC solve their personal problem *right now*. Again, we have tens of thousands of machines in the field now, and thousands more every day. You personally may care about, say, Java in your browser, but it is not a priority for OLPC, by which I mean the 3 people I sit next to. No, tell me how you really feel... Which is the OLPC you care about? You and the 3 people sitting next to you? Or the tens of thousands of machines in the field? Where do the children fit in? How about the 8 XO's I purchased. Do you care about them? Or the children who can't use them to run their web-based self-paced mathematics instruction? It reminds me about the parable of the tens of thousands of starfish washed up on the shore. One man stoops, picks one up and throws it in the water. The man next to him says, There are too many. It won't make a difference. The first replies, It made a difference to that one. Don't try to imply that #6454 is a personal problem or that I'm the only one out banging my head up against it. I didn't open it, though I did report my findings in it. FYI #6454 was opened 4 months ago, last updated by me 3 months ago, and never assigned or commented upon by a OLPC or 1cc employee. So please drop the dramatic characterization by implying that I was demanding it be fixed *right now*. Did you bother to read #6454? You certainly didn't update it. Good thing I've spent the last hour trawling through OLPC developer list emails to find out that I am not a priority. It is not part of the software included in our large scale deployments. Ah, but the OLPC has told the public java can be added on after the fact. And what you've told people isn't entirely true. Furthermore, it isn't clear that it ever was true. Your documentation on how to do it is wrong. And the trac ticket is being ignored. I'd like to make it true. By all means work on the problem, and we will certainly help you publicize the solution you come up with as much as we are able, but there are not resources to devote to every feature request. We have to prioritize. Ok. Where is your list of priorities? How does that map to the list of open Trac tickets? Are the milestones dates or features? Will it be the same next week?

As with 2, it would still hold if recipients were actively encouraged to get developers keys if they have any interest in having full control of their machines (indeed you could say that they we would have a much better test of the dev-key acquisition process, which currently works more clearly in large batches for countries than for individuals). i would have thought G1G1 proved that dev-key acquisition works just fine. paul =- paul fox, [EMAIL PROTECTED] (arlington, ma, where it's 64.9 degrees) ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: what about having network connections inhibit sleep?
what do people think about the idea of making the existance of established TCP connections inhibit sleep? What release are you running? Auto-suspend isn't enabled in production releases. Joyride should be awakened from suspend by any received unicast (TCP) packet, so I'm not sure why you saw it hang in mid-download, if the update was one long continuous TCP download. But if it's rsync, maybe it's driven from the client end (and if the client suspends, the server never sends anything further). The real fix is to only force a suspend when the kernel knows no process is scheduled to run now or soon, and ato waken in less than a whole second. We're slowly working on those issues. If we keep kludging things like TCP, there's never the time to put in the real fixes. John ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

In that regard, FWIW I found the various infos I later could find from olpc a bit unclear or even seeming at first glance inconsistent about how usable a G1G1 XO could be as-delivered.

But if it's rsync, maybe it's driven from the client end (and if the client suspends, the server never sends anything further). olpc-update should be touching /etc/inhibit-suspend before it does its work, so it should not be sleeping. If it does, and your build was not ancient, it's a bug and I'd like to know more. The real fix is to only force a suspend when the kernel knows no process is scheduled to run now or soon, and ato waken in less than a whole second. We're slowly working on those issues. If we keep kludging things like TCP, there's never the time to put in the real fixes. Yes. Better integration of suspend and the kernel scheduler is discussed near the end of http://download.laptop.org/content/conf/20080403-olpc-mini-conf/Power/ but I don't think we've made any measurable progress on it since then.

Tying pretty boot to machine-lockdown is arbitrary. agreed. as a G1G1 owner i wanted to see the boot messages quite a long time before i needed or wanted a dev key. http://wiki.laptop.org/go/Cheat_codes the 'check' key is what you are looking for. 1. is an interesting argument. As with 2, it would still hold if recipients were actively encouraged to get developers keys if they have any interest in having full control of their machines (indeed you could say that they we would have a much better test of the dev-key acquisition process, which currently works more clearly in large batches for countries than for individuals). i would have thought G1G1 proved that dev-key acquisition works just fine. That's my hope. Shipping G1G1 with security enabled forced us to properly prioritize bugs with dev key request/fulfillment, and to build tools to make requesting a dev key easy. That was a success, from my perspective. I'd like to be able to offer the same antitheft protection we will be trying to offer Uruguay to G1G1 users as well, on a voluntary basis, and roughly the same reasoning. If something goes wrong or it doesn't work like it should, G1G1 users are communicative and English-literate canaries in the coal mine. And diagnosing and fixing the problem is much easier for G1G1 than it is for some small village in Uruguay a week's walk from anything. But again, my perspective is warped by having to write this code and be confident in its correctness.

The LED stays on for a while and turns to off, and come back to on, etc. If I press the power button while the abnormal LED pattern is going, the button press is often ignored.

I forgot to mention one thing. So, Ties, you might be already doing this, but one workaround for the problem is to instruct kids not to touch the keys or touchpad when the unit is suspended... -- Yoshiki ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: [Server-devel] Edublog notes (was: Re: The road towards xs-0.3 - update)
Hi Martin, You're right we are closer than I thought on first read. Thanks for the added comments. I want to minimize the scope but I see feature creep coming so we better plan for it in advance. Here are some comments on these: - understand a simple level of identity roles (provided by XS facilities, as we've discussed) GS - Agreed. - let users blog, tag, etc - let users mark entries as draft/public/etc - show user's blogs locally GS - On these three: I want the blog hosted elsewhere. There will only be two states for a blog post: draft (AKA stored local or maybe on XS) and Posted (AKA done and sent to blog or sent to teacher for approval). Maybe that's three, Draft, Posted, and Pending approval. Once Posted all posts will only available on the hosted blog. Perhaps a list of URLs to previous posts can be stored for the user but the actual blog posts themselves are only saved at blog hosted site. - allow teachers to approve something for publication GS - Definitely a core requirement. - push queued entries to a remote blog GS - Good point about queuing. We need the right algorithm for retries if connectivity is intermittent. On these: 1 - the school is super-connected to the internet, and everybody publishes _directly_. In that case, we don't need the software - let's just use blogger.com GS - We still need the EduBlog SW in this case. The kids can't easily use blogger.com as it stands now. Problems reported are: User/pass, too many steps to post, can't find URL and no teacher approval/edit. All flagged as critical problems by the user. Good BW and target blogger.com is the use case which first initiated the project. 2 - the school has spotty or no connectivity, and perhaps you want to run a local school blog, not visible for all the world to see. _Some_ entries are tagged public to the world and those get pushed to blogger.com/drupal/moodle GS - This is the secondary use case but clearly a critical need. The intention is to treat it exactly the same as the first but with the target blog being local to XS or LAN. Great comments, thanks! I want to find a minimum achievable set of features that still meets a critical need. Like all successful SW it will live long beyond my time on it so now is the time to architect it for extensibility. I see we need a really good DB data design. I'm not sure that the current team has that experience. If anyone out there wants to help with that let me know ASAP. The replication/queuing posts problem will be a tough one too. Is there any core XS work planned to handle queuing HTTP or other traffic aimed at the WAN? I'd like to pass the buck on that :-) but if nothing is planned we can try something basic like try three times then wait an hour and repeat. I hope we come out of this project with a recipe and key decision points for build any XS hosted Web App...

I will snip the many points of agreement, and focus on the interesting parts... - let users blog, tag, etc - let users mark entries as draft/public/etc - show user's blogs locally GS - On these three: I want the blog hosted elsewhere. There will only be two states for a blog post: draft (AKA stored local or maybe on XS) and Posted (AKA done and sent to blog or sent to teacher for approval). As a user, when you are writing the blog entry you need to post and be able to see a preview and edit. That means that we cannot avoid input validation, formatting, etc. Also - we cannot avoid some user management, and database management, however simple. Maybe that's three, Draft, Posted, and Pending approval. Once Posted all posts will only available on the hosted blog. Perhaps a list of URLs to previous posts can be stored for the user but the actual blog posts themselves are only saved at blog hosted site. In any case, that has pushed us into a territory that means that we have to do a lot of the work that forms the core of what a blog is. That is why I am saying we cannot avoid it, and should be reusing an existing blog. If you want to do it the easiest way - take Moodle and customise its existing blog facility to support - teachers can approve - approved posts are pushed out to a public blog and you will have plenty of time to spare - which we can use to tweak moodle a bit :-) I see we need a really good DB data design.

I hope we come out of this project with a recipe and key decision points for build any XS hosted Web App... My hopes are the same. That's why the first rule is: do not start developing new sw if you can avoid it.
