Re: [support-gang] XoPhoto needs a few intrepid testing volunteers.
Hi George, I'm really excited about the release of this version of XoPhoto. The timing is really great because I have been meeting with a local (to Washington, D.C.) nature photographer who is adept at getting grants to deliver digital photography experiences to at-risk youths. I will be setting up another meeting with her to demo the activity. We still have around 20 XO-1 laptops in our lending library that would be great to use in an outdoor photo exercise with kids.

Re: XoPhoto needs a few intrepid testing volunteers.
I took a brief look at it on a fedora 64 sugar emulator (luckily it doesn't have a camera hardware dependency 8-) CPU utilization fairly high on it for a while, iirc and may have crashed sugar, will see if indeed it does it again, to bug report somehow. Glad to have another activity, even if in alpha/ beta.

Re: Re: Re: XoPhoto needs a few intrepid testing volunteers.
Hi Tony and all, This is the way I think XoPhoto works, and does for me on build 850 1.5. When XoPhoto loads, it checks for at least 10 images, (mime_type .png,.jpg,.tif). If there're not enough to play around with, load 11. If there are more than 10, don't load the journal with anything, just create the thumbnails, and store them away in sqlite database. The storing in the journal takes time, and the thumbnail generation does also. Thereafter, at startup, look for recent images, stop when datastore find returns one you've already seen (assumes most recent first, which is, I think, the design). So your observation is interesting. I haven't experienced multiple copies of the test images in the journal. I think I would have noticed that, because I've been working so hard on latency, I've been paying pretty close attention to delay. I also looked back in my journal, to make sure I wasn't missing something. But I don't want to discount the possibility that os373 is different. The journal images can be deleted pretty easily, when the user is done with the (currently non-existent) tutorial -- just drag the images to the trash, and then empty the trash.

This I expect is what happened, I had 2 of my own images, it installed 11 more, I deleted 4, ran it again and it installed 11 more.

Re: DHCP option 119
Summary: the option is supported, but not requested by the DHCP client in the current builds. The search value is set to the domain name. Tested using os852 on XO-1. The result will be the same on XO-1.5. 1. the DHCP Request emitted by the XO does not contain a domain-search (119) request, therefore not unexpectedly there will be no reply that will contain it, and no use of the data, (method to test was to capture packet stream with tcpdump and analyse with wireshark), 2. a manual request for the purpose of testing can be formed by turning off Network Manager, and using dhclient -R domain-search eth0, and this correctly includes the domain-search (119) item in the DHCP Request, but as my DHCP server does not provide this item there was no response to the option, 3. there will likely be some method by which Network Manager can be directed to pass -R domain-search or an equivalent to dhclient via the -cf option, but offhand I don't know what it is, 4. /sbin/dhclient-script does contain logic for handling the domain-search (119) reply, so if an XO is configured to request it we know the reply should be handled, and the /etc/resolv.conf file properly updated, 5. in the absence of domain-search (119), the search tag in /etc/resolv.conf is set to the domain-name option value if any. 6. a deployment customised build could potentially be produced that implemented domain-search support. The domain-search option to DHCP is defined in RFC 3397. (Opinion: it seems to be a crutch for badly designed namespaces or failure to use reasonable alias names. A large search list can have a huge impact on clients and a network, since queries may be repeated until satisfied. I recommend against using it in a deployment of XOs, due to the potential for increased DNS requests helping to saturate the radio environment.) -- James Cameron http://quozl.linux.org.au/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: [Server-devel] Mass OLPC XO chargers
Is effective. Same idea was mentioned earlier this year. Looking at the photographs, a modification I suggest is an inch of heatshrink tubing over the black and red cables as they exit the DC plug. This is so that the stress is distributed and the connection lasts longer. Another suggestion: four self-adhesive rubber feet on the metal box. Would help to avoid scratching plastic chairs, would raise the box for better cooling. -- James Cameron http://quozl.linux.org.au/ ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

It's simply a missing dependency in ds-backup-server, but it broke all schoolservers worldwide ;-) After installing syck-python, ds-cleanup.py still doesn't seem to do anything. I'll figure out why another day, now it's 2am again. There's more than that. It's a tool that makes you really think through the changes that your making. It helps you centralize everything. It also results in a configuration that results in the ability to upgrade from any point in time to the latest version. It would be less error prone in many ways. That's true. The problem with this sort of tools is that it's very hard to diagnose what went wrong. On a puppetized machine, a rule containing rpm -i package; do_something failed after the first command for some obscure reason. Then, the first command would also keep failing because the package was already installed. This time we could blame it on the incautious rule author who forgot --force, but you see what I mean: error paths become complex with puppet because the flow control is non-linear (like in make) and rule execution happens asynchronously and in thebackground (even more obscure than make). And if you have a mix of offline and online servers, its a no-brainer. The puppet benefits (vs shell script) for connected servers are very significant. And if you can just take a few easy steps to share the configuration with your offline servers, you save a lot of time. That is true. OTOH, one could also share a script to be executed off a USB stick or over the net with Puppet. As ugly as it may sound, humans would probably find it easier to maintain linear code that could be debugged interactively from the command line, independently of an asynchronous client/server system based on interdependent rules.
