Re: Scheduled server maintenance: 9/7
This maintenance has ended. The only change was an upgrade of trac to a more recent version by coderanger. New tickets, adding comments, changing tickets, and attaching files are all tested and work. The rest of the planned maintenance will be rescheduled to a future date. If you have any issues, reply to this email, or bug me (djbclark) and coderanger on #oftc. For urgent issues, you can use djbclark: URGENT in IRC, and I will receive a SMS TXT message; or if you are internal, feel free to give me a call or direct SMS TXT at any point in time. -- Daniel Clark # Sys Admin, One Laptop per Child # http://laptop.org # http://opensysadmin.com # http://planyp.us/djbclark # http://dclark.us On 9/6/07, Ivan Krstić [EMAIL PROTECTED] wrote: Public-facing development services (bugtracker, git, development hosting) will be partially offline tomorrow, Friday the 7th, for a migration to different hardware, concluding the emergency maintenance from earlier this week.

Re: save-nand problem
Hi Kim Did the image you created installed OK? I used your Crcimage.sh and obtained the same result as before. I was already using pilgrim to create the crc files. One think that I forgot to report is when I use the crcimage(pilgrim) command it's returning a message %crcimage nand.img Input file size is not a multiple of 0x2 - residue 0x1e000 Is that normal?

Juliano, I was able to create a mac version of this crcimg executable; I will add that to the Customizing nand wiki page along with the linux one. Are you working with a linux environment?

Re: Pippy and Calculate - Evolution Solution
Ivan, You can almost tell that he is pretty much the only guy who is interested in supporting outside developers. That isn't fair. I speak on behalf of the entire OLPC team when I say that we're extremely interested in supporting outside developers. There's no question about it, and there never was. My wording was not right. I didn't mean to say you guys *don't have* the interest, but happen to have not been able to spend time on it. (And, kudos to Bert was my another point.) Sorry about that. Until then, I can only thank everyone who's been bearing with us even if it feels like there's a line in the sand between 1CC and outsiders at times. Communities are hard work, and we're entirely committed to growing a great one around OLPC. Really. Please be patient with us a little longer, and as Wikipedians like to say, assume good faith. Yes, thank you. -- Yoshiki ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

I speak on behalf of the entire OLPC team when I say that we're extremely interested in supporting outside developers. There's no question about it, and there never was. What's also true is that -- so far -- we've been in the unenviable position of having to grow a platform (both Sugar and the distro) with heavy low-level development taking place _in parallel_ with high- level activity development. This is extremely difficult to do in any set of circumstances, and doubly so with our resource constraints and timelines. As a result, we haven't been as good as we could be about leveraging the community and outside developers. We're fully aware of this, we know it can be really frustrating for contributors, and we're determined to get better. I expect things will improve significantly in this domain in a couple of months as underlying platform development begins to stabilize and our focus turns increasingly towards activities and other consumers of our platform and APIs.

Cheers, Hmmm, 3 months ago I asked either for a physical machine or a telnet account for a locked down physical machine to test the Geode processor (LX). I have expected that I will not get a physical machine since there are a limited number of these kind of machines and my work is very low priority (and I do not have C code right now) but it was a little surprise that so far nothing happened about the account. Since my code depends on the hardware and the Geode manual is close to useless it effectively stemmed my work. I tried to run my little tests via this mailing list and there were some kind people who took the time to help me but it turned out that the Geode is below my worst expectations and so requires a lot more tests than my patience. (Programming via this mailing list is just as productive as scheduling your punch cards in the old mainframe days...) For the record, a Geode LX-433MHz has the MMX performance of a Pentium MMX-133MHz if my tests are right what I simply still cannot believe... So I am aware that you have a lot of work to do right now and I am aware that 3d rendering is not at the top of your priority list but from my viewpoint it is nonexistent developer support. Never mind, it was just my frustration. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

I'm not sure how you went about previously requesting an account; I handled almost all l.o accounts until a few days ago, and I never saw an e-mail from you. I have sent an email to [EMAIL PROTECTED] (as it is written in the wiki) and after that exchanged several emails with Jim Gettys. The conclusion was that he said that when I have something running then we can come back to my request. The problem is that I need to run those tests to start coding in C (I have a proof of concept in C#) so it is a catch-22... SSH2 key: I am not sure whether we are talking about the same thing. I need an account for an XO machine which is connected to the internet so I can access it from here (and I have a feeling that you are talking about a project hosting account but I can be wrong). So if I am right and you have not already set up an XO machine then you have to do the following: 1. Take a developer XO (must be B3 or B4 - LX700 and must have GCC). 2. Plug in an USB-Ethernet adapter and configure it in Linux. 3. Take apart the XO and remove the wireless antennas. 4. Install telnet and FTP. 5. Plug it into your router and either put it outside of your firewall (so it will not be able to access your machines inside of your firewall) or set up the router to forward telnet and FTP but prohibit any outbound packets. 6. Email me the passwords for telnet FTP. (2 and 3 are needed if I am an evil hacker since I am not sure if wireless can be firewalled adequately.) We haven't had the cycles to set up a OLPC system for normal development; however, we have recently hired a system manager, and can put it on his queue to set up. - Jim If it turns out that we are talking about the same thing (and you have already set up such a machine) then I will need some time since I am a Windows programmer and have no idea how to connect from Windows to Linux via SSH...

It is neither the gaming platform nor the 3D workstation you're looking for. There's nothing surprising about that. There is. If my tests are correct then it is the first time in history when somebody created a processor which runs MMX slower than integer instructions. See http://wiki.laptop.org/go/Geode I have downloaded the MediaGX guide (the predecessor of the Geode) and in that guide at least both the latency and throughput were defined. According to the tests the Geode LX has half the performance than the MediaGX clock by clock.
