You already know the area you want to work on. Do a bit of background research -- we've exchanged some emails on this list about that for example, and we mentioned a few existing implementations of webbased config tools, and I've posted some hints. If you can do an initial research on those, and in your GSoC application discuss what you've learned, and what your draft plan would be, fantastic. Don't let that take all your time or space though - there are other things you'll need to talk about like schedules, etc. Also - keep your eyes open - I'll be posting a few roadmap-related notes, and we're likely to have a phone conference to discuss plans soon. cheers, m ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

I have certainly been mulling on this -- I have experience with both, and my intention is to define a simple, but effective set of criteria and see which DB meets it best. The key webapps we care about support both (I did the support of the Pg port for a while for Moodle), support for Pg is growing and SQL syntax is converging. So support in webapps we care about is no longer the monster it used to be. One of the key metrics I will take into account is behaviour in low mem conditions -- and I plan on asking MySQL devs and Pg devs to give us a bit of help configuring them. Off the cuff, I'd compare... - Stability / sanity - Good performance & behaviour in memory-constrained, low-end HW scenarios - Our core webapps/apps/libs support it - Strong dev community - multiple vendors contributing on one codebase - one or more talented and respected leaders - can resolve conflicts - growing dev activity (number of patches, number of authors) - Random apps out there support it (long last in priority...) the strategy of giving the community a significant weight is what I followed for OSVLE to pick an LMS. It picked moodle back then when it was clunkier and had less features (at first glance) than the rest. But the architecture made more sense, and the community was on fire - I'm ready to make the same "mistake" again! ;-) cheers, martin ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

Re: [Server-devel] Database on server
I hope not a religious war on my part. I am happy with both choices abstractly (and I am a big user of sqlite3 as well, which is excellent but not so much for multi-user update-heavy applications). My point (and this whole comment is certainly directed at Martin, who is the ongoing developer) is just that after installing many open-source projects that have database access, there seem to be a non-trivial number that don't support PostGres but do support MySQL, so it might be helpful to make that the pre-installed database. As to Sameer's point that anything can be installed after the fact: that's true with a reliable connection. Having just spent several weeks in connectivity hell, I can assure you that trying to do "yum install" over a line that has frequent glitches is miserable, so it would be kind to try to make "most common" decisions in the base install. (And drupal, btw is one of those packages that supports both databases.) ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

I strongly think that instead of picking favorites (we have a LOT in the pool to pick from:-)) we should establish the need first. Use case -> Need -> Applications -> Packages So, in Carol's case (hypothetical example): Carol's case -> Blogging -> Drupal -> Apache, MySQL, PHP After all, even if the DB of choice was MySQL, nothing's stopping me from installing PG on it! Also keep in mind that while there will be significant overlap across different use cases, but I doubt it if we can get away with a single XS build combination.

Smells like a religious war to me. You are correct that postgres is in the build, but nothing currently requires it. The idmgr package is using sqlite instead.

[Server-devel] Database on server
I notice that the pre-installed database for the xs build is PostGres. Now I have nothing against PostGres. It is a fine database, and was a "real" (ACID) database from the start, unlike MySQL. I certainly advocated that it be used in preference to MySQL for de novo projects at clients in the past. But from the standpoint of making a choice that enables the most other open source software to be installed and to run without difficulty, I believe MySQL would be a better choice today, especially since its former deficiencies have largely been rectified. In summary this is a recommendation based on a desire to lower the development costs of reusing software, not a theoretical determination of which database is "better". Any thoughts?

Re: [Server-devel] Drupal on OLPC? (Martin Langhoff)
Hi Martin et al, Thanks for the comments and direction. I'm still working on options for the Uruguay requirement (BTW now rewritten, verified with tech lead in Montevideo and posted in wiki at: http://wiki.laptop.org/go/Requiremientos_Para_XO). We want any new work to be available in all deployments. Unless the XS base install works for teachers and students out of the box, we need to go where the most development support is available. Looks like you suggest current Moodle and MediaWiki plus possible added code (may be outside XS scope, e.g. client side or system level) unless we get great traction with Drupal team. If we get that traction how we do we make the solution broadly available? If we focus on Moodle and Media Wiki do we work directly with those projects or look for some maintainer/lead developer support from OLPC? On the drupal front, perhaps we can have a model where XS code can be added like activities are added to XO. E.g. core activities plus downloadable additions via well defined install. The great thing about this project is that we get direct user feedback from a real XO deployment! So Uruguayan technicians, teachers and students are part of the design from the start. For now, we will try all options until we find a viable design and developers interested in pursuing it. Any additional input on where to focus efforts re: developer recruitment and target software is greatly appreciated. Thanks, Greg S I do think Moodle i very strong in all course or student-group content and activity mgmt, and getting better all the time. It's patchy in the "general content for everyone", where MediaWiki shines, and we will also have MW there to host partial Wikipedia content. There has to be a strong case for a 3rd system that overlaps so much with those 2 -- each additional system is a significant burden, as we will have to customise it quite a bit. Having said that, I _like_ Drupal, and it can be used usefully, but we are entering diminishing returns region (from a core OLPC team POV), so if the Drupal community can help get this in shape, that would be great. IOWs it won't be a priority for me. cheers, m ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
