 Your analysis conforms with my experience. When I tried to carry mod_python

It is my understanding mod_python was dropped as a supported package beginning 
with fedora 18.
mod_python upstream has not been updated for years it seems.
It is my understanding that mod_wsgi has a better memory foot print than 
mod_python.

 I'm sort of looking forward to debugging my new version of ds-backup server, 
 which uses mod_wsgi. It seems like a relatively localized change.

  Is it ok to just carry the fc17 version along in our repo, and try to see if
  it just works, or should we set a goal of rewriting to mod_wsgi?
 
 Carrying along an old mod_python might be tricky, I think F18 has a
 new apache version with some incompatibilities.
 
 I would port it to wsgi.

Re: ARM motherboards

2012-09-12 Thread rihowa...@gmail.com
Sameer,

I see you already found a mention of MPICH2 .  Coincidentally  was going 
suggest this coming Saturday as something to demonstrate at OLPC-SF.
http://www.mcs.anl.gov/research/projects/mpich2/

http://www.mcs.anl.gov/research/projects/mpich2/documentation/files/mpich2-1.4.1-installguide.pdf

I know it is outside the scope of OLPC but it would be interesting to see what 
this type of message passing interface could do on a group of XOs.

  Both answers should be available from the email listed in the blog:

  Any other details?
 
  We've supported this from the beginning by design.   Kits have been 
  available
  as spare parts for deployments to purchase.  Upgrading an XO-1 to an XO-1.5
  or higher motherboard requires the insertion of a small metal bracket to 
  hold the
  WLAN card.   The XO-1.5/1.75 chassis are mechanically identical.
  Upgrading an earlier laptop to an XO-4 motherboard will require a
  small rubber piece inserted to change the size of one chassis hole
  from USB to micro HDMI.
 
  Unfortunately, the mechanics of XO-4 Touch mean it cannot be retrofitted.
  You can get the higher performance by upgrading to an XO-4, but sadly
  no multi-touch support.
 
  A kit includes all the parts needed to upgrade a particular laptop model.  
  In
  addition to a motherboard (if XO-4 with an internal connector missing)
  this generally includes a new heat spreader, a WLAN card (if needed), and
  conductive foam/tape as needed to improve the ESD shielding of the earlier
  chassis.   We do perform some testing of older laptops upgraded to each
  new motherboard design in order to construct appropriate upgrade kits.
 
  Cheers,

 Thanks for the details.
 
 I was walking through a replacement workflow in my mind for my Jamaica
 and India projects, and I realized that if/once the upgrades are done,
 one would be left with several older working motherboards. What's to
 become of these? If someone could design a chassis to hold a bunch of
 boards together...imagine a Beowulf cluster of these! (sorry, couldn't
 resist).
 
 Is that a lunch box? No, it's my Beowolf cluster. Can I compute
 something for you?

I can confirm what you are seeing with build 20 12.1.0 and Browse and asking 
for a developer key.
By the way the OFW I have is Q2F12.

At least with this version of Browse hml5test.com displays without crashing.

 That kind of approach would suggest supporting both CentOS and F17+.
 I'm not sure if thats the direction we'd want to go - supporting 2
 platforms has its costs. It might be preferred to do a full migration
 to F17. You'll need clarification from this from Martin, who's away

There is no CentOS for ARM.  It is not even on the horizon yet. On the other 
hand rpmfusion has recently expressed interest in building for the 2 ARM
archs supported by Fedora.
I have been targeting F17 for ARM with an eye to F18 for ARM which may 
make the cut to become a primary architecture.

 
 Earlier, I started using the git sources at dev.laptop.org, and I discovered
 that there did not appear to be an obvious set of git repos, corresponding
 to XS-0.7. Paths for repos that had the most recent changes included:
 
 /packages/
 /projects/
 /bios-crypto/
 /users/martin/
 
 Any suggestions on how we should proceed?
 
 I think you just need to sit down and hunt these down. It shouldn't
 take you long, using version numbers found in the most recent RPM
 packages, etc.
 
 Many of the XS component webpages have links to the git repo, e.g.
 http://wiki.laptop.org/go/XS-rsync
 
 If there are ones that don't, maybe you can add the links.
 
 And if you really get stuck, you can ask for help for a particular package.

George,

A while ago I asked for clarification about which git branches where the 
correct ones to pull from and never got a satisfactory answer.
I had a few things I wanted to submit as patches but have been holding back on 
it.
Meanwhile I had a few equipment failures and had to rebuild some drives and 
used my main ARM system for testing the evolving F17 for ARM which has finally 
gone GA. ( Along with some disruption from a flood which fortunately missed the 
XOs).
I think the approach overall that I have been taking is a bit different from 
yours as my long term goal is to support the 2 current ARM archs that Fedora 
currently is built for and trying a few other new things to make the components 
used to be more similar to what is upstream.  This is possibly a more 
experimental approach than you are using.  Part of my plan is to set up my own 
ARM based Koji system.  I have enough ARM devices to do this but need to order 
one more to make it more viable.
 Maybe we can compare notes in October...at the OLPC-SF 2012 Community Summit.

This is a known problem with the TrimsSlice and has been documented on the

Fedora 17 for ARM is just approaching the end of alpha development and a fix 
may appear soon if it has not occurred already. 
The place to ask about F17 for ARM is at the fedora arm email list.

 I also cannot configure an ethernet dongle, which the kernel doesn't appear

 Any pointers to documentation, or what modules's source I might study? I

 I don't know yet what software the XS is composed of, but since I have

Re: [Server-devel] [OLPC School Server] Comment: First Learnings about ARM

2012-04-15 Thread rihowa...@gmail.com
George,

The Dreamplug may not be the best device to use at the moment as I learnt 2 
days ago that the board design has changed very recently and it will be a while 
until the required code changes are made in the mainline kernel code ( and the 
mainline u-boot code).  I have emailed the maintainer of the dreamplug code  
about the board changes.  If you have one of the new boards a kernel built from 
 mainline kernel source will not work.  Others have tried and failed.

Do not follow the trimslice directions as they are for a completely different 
SOC and board design and it stores uboot differently.
What works for tegra based boards will not work for kirkwood based boards.

I have on my to do list for the Fedora ARM project to create instructions for 
setting up uboot for kirkwood based systems. ( I have several different 
kirkwood systems in my ARM collection). I had been waiting for one of the 
olpc-sf members to return from overseas so I could inspect there dreamplug and 
run a few tests.  Now the new dreamplug board design adds a new wrinkle to 
this. 

Base the offset off what was used in the Dreamplugs default environment as 
shipped to you. If it does not boot successfully it could be board 
incompatibility.
I have not been able to find either a Marvell or GlobalScale repository with 
code for the new design.  I assume it will be published at some point in the 
future.

Well need to get back to working on ARM XS stuff.

 fatload usb 1 0x640 /boot/uImage
 
 But when I load the uImage to memory at 0x640, and bootm 0x640 (how 
 do I know that that's the correct load address -- I copied the trimslice 
 directions), I get no response.  When I do the same with a kernel supplied by 
 compulab for the dreamplug, it seems to function properly, ie. it boots to 
 the point where it is looking for the rootfs (it gets further in the boot 
 process).
 
 Is there any documentation on how to proceed in FC17 with the supplied 
 kernels? Maybe I should just cross compile to get to a uImage?

 Oh really? I'm assuming it'd be in the facter code, using lspci and
 dmidecode to get the facts about hardware

I just checked ARM Koji and it looks like puppet is building okay on ARM and 
passing the tests on ARM.
I must be remembering some problem it had during the fedora 15 moji phase, but 
then 
a number of things had problems then.

 If you have time towork with us through some hitches, I'd recommend an
 ARM server. At this stage I'd say one of the Marvell/Globalscale
 Plug servers (dreamplug for example), or a trimslice.
 
 Either option will need a combination of the OS on internal SD/eMMC
 and the storage on an ext HDD (via USB probably).

The Kirkwood based systems such plug computers can boot both the kernel and OS 
from a hard

going 
to send them an email about what is involved and some other things about the

[Server-devel] XS on ARM update.

2012-04-11 Thread rihowa...@gmail.com
Martin,

I have been meaning to email you an update about XS on ARM for a while.
I had to take a hiatus from what I was doing with it, but started back on it a 
while back.

I had been experimenting with getting XS components running on ARM.
That was with Fedora 13 for ARM. With Fedora 13 for ARM ejabberd behaved nicely.

 I was in the process of moving to Fedora 15 but then Fedora 15 stayed in 
perpetual
alpha and I wanted to be on a release that was well supported.
Then Fedora 17 for ARM koji is building much faster than expected 
so I am in the process of moving over to Fedora 17. 
Note that currently Puppet relies on some hard coded intel specific code.

I would like to chat with you some time about this as I want to discuss what is 
essential 
for the XS and which is the correct git branches etc to pull from for some olpc 
specific bits.
.

Tried this build with an XO-1 and it boots OK.

It can connect to my wireless router.

Frame key does not invoke the Sugar Frame.

It try to use Browse to open a page, for example www.google.com, opens but then 
crashes straight away.
Note that I ran software update form the Control Panel and it claim to update 
Browse from 133 to 134 but still showed 133 in the list view

Running ping in the Terminal activity returns:
 ping: icmp open socket: Operation not permitted

SDHC card in the XO-1's slot is not auto-mounted. 
USB drive is not auto-mounted.

I have not tried any other activities or gnome.

 THIS IS A DEVELOPMENT RELEASE
 
 The release is our first combined 12.1.0 / Fedora 17 release, such a
 small release but represents so much time by so many people in both
 OLPC and Fedora in the ARM side of things to get a hardfp ARM
 release.
 
 This is post alpha F-17 so the major churn for Fedora development is
 now closed. Also note this release has the usr move too. The major
 features destined for Fedora 17 can be found here [1]. This is the
 first release using the new file naming scheme, details can be found
 here [2], it will allow an easier means of identifying builds, in
 particular makes it easy to differ a x86/arm build :)
 
 Some of the notable details of this release are:
 - First 12.1.0 combined release for all devices :-)
 - Fedora 17 devel release [1]
 - ARM hardfp release for the XO 1.75 (note old F-14 armv5tel binaries won't 
 run)
 - Latest Sugar 0.95.x devel releases
 - gnome 3.4 RC
 - gtk3 3.3.20 with multitouch!
 - xorg-x11-server 1.12 with XInput 2.2 (Mutlitouch).
 - plymouth pretty and fast boot
 - 3.3 based kernel for x86 XOs
 - 3.0 based kernel for ARM XOs
 - The latest firmwares
 - only 4Gb images, for 8Gb expand the FS, we need to review dependencies for 
 2Gb
 - a lot of various improvements

I noticed that with my XO-1 that it would come back to sugar after a short  
time.
We registered the XOs with the XS. Kept Browse open and tried to look at some 
web sites. A couple of us tried to use chat.
That is the basic scenario of what we tried to do with the XOs.
I'll have to ask the other people involved in the test if we can together and 
try this test again soon.

 One pattern we've seen is that on XO 1.5 build 883, it keeps
 restarting X (gives some dcon freeze message) periodically. On a XO

 Unfortunately, a bug in the firmware update code means that these

 Users of 11.2.0 and previous (who will be running older firmware

I think what was used to generate the help was the FLOSS Manuals Remix feature, 
http://en.flossmanuals.net/index.php?plugin=remix .
The workflow would be to identify the source of the existing help text starting 
with the Sugar and XO books. 
Edit the source material then use the remix feature.
I would suggest saving the original books to preserve those editions for people 
still using older versions of the software.

 To be honest, I don't really know. Here's what I know:
 
 - open the help activity
 - look at the left-panel navigation TOC
 - open the Sugar manual -- you'll see lots of topics aren't there!
 
 So the topics that aren't there are in general from manuals about a specific 
 activity. There is also a flossmanual about the XO itself -- I think some 
 chapters from there have been included.
 
 On flossmanuals, there is an option to make a book or something like that. 
 When you do that, it lets you pick and order chapters from many manuals. 
 Perhaps that's what's been done -- perhaps the mix was prepared on the 
 flossmanuals website.
 
 It is trivial to see if you look at both the Help activity and the stuff on 
 flossmanuals.

Hi folks,

Many GNU/Linux distributions are doing some ARM porting; this tends to
result in work duplication, and there doesn't seem to be a general
purpose forum to bring ARM porters together.

We're inviting developers of GNU/Linux distributions with an interest
in ARM to join a new cross-distro list, hosted at Linaro:

  http://lists.linaro.org/mailman/listinfo/cross-distro

Any ARM Linux / Free Software discussion is welcome on the list, for
instance porting software to build on ARM, toolchain problems, dealing
with new ABIs, Thumb-2, NEON, kernel problems, announcement of new
tools etc.

Works fine from here.  I have tried several times over the past 24 hours and 
the connection worked ok each time.

 Silly question:
 
 On a scale of 1 to 10, if all of our XO's in deployment are security 
 disabled, we never do an online update, and all boot fine on os23, what is 
 the opinion on using os23 to install, and then updating just the changed 
 modules from there to those in the RC to keep the ubifs snappy behaviour?  1 
 would be horrendously stupid, 10 would be harmless and smart if you get 
 all the modules in sync .  My fear is the answer is going to be 5. might 
 work, buyer beware, and I have to use my own brain to make a decision  :-)

 Strange. Perhaps just a network issue - try again tomorrow.
 
  2) Meanwhile, I've hooked the serial adapter up onto an XO with a fresh 870,
  and tried to boot with the USB2VGA adapter plugged in.  Watched the messages
  stream by, nothing seemed amiss.  Main screen still sticks at the one dot,
  no life out the adapter. However, hitting enter on the console session
  attached to the serial adapter does bring up a bash prompt, so it would
  appeaqr the system isn't actually 'hung' .  So far all I've entered is
  'reboot'.  That works :-)   Do you want me to try those same mod commands
  you had me previously try at the terminal prompt?
 
 Thats interesting. Enable logging on your serial console. Let it boot
 and hang, then press enter to get a bash prompt.
 
 Wait 5 minutes - the kernel may detect a hung task and spit out a load
 of diagnosis. If this happens, end the session and send me the log.
 
 If everything stays quiet after 5 minutes, run:
 echo t  /proc/sysrq-trigger
 
 This will output a lot.
 
 Then send me the log.

Re: [Server-devel] XS-0.7 plans -- your thoughts please...

2011-01-18 Thread rihowa...@gmail.com
Martin,

I was about to email you regarding what is the latest XS version as I am about 
to get back to attempting to port
the XS to ARM so your email is timely to me.
I had put that on hold for quite a while as it turned out Fedora ARM 11/12 
lacked a number of items required by the XS.
The Fedora 13 ARM port is intended to be a complete a port as possible and 
should have the bits required as a base for the XS.
After the Fedora 13 ARM port is released it is my understanding that the Fedora 
14 ARM port will be started.
I hope you keep the Fedora RPMs as RHEL6/CentOS6 do not support ARM.
I have been experimenting with  ARM devices as servers with low power 
consumption and I want to prove the viability of using them as an XS.
The systems I have are based on the Marvell Kirkwood, (not quite as fancy as 
the Armada 610).  If successful this would be an asset that uses little 
electricity and would help with deployments in locations where electricity and 
server room cooling is expensive.

In my review of the make files for XS-0.6 I have noticed that the architecture 
is hardcoded in a number of places.  It would be nice if these were 
parameterized.
The other area that seems a bit strange is how flat the git is for the XS 
components.  They all seem to be at the top level. It would be nice if they 
hung off a top level XS project directory with a master make file that passed 
arch type, etc., to the component make files. This would make it simpler to 
clone all the bits.

If you want to read more about the Fedora ARM project here are several links:-
http://fedoraproject.org/wiki/Architectures/ARM 
http://arm.koji.fedoraproject.org
http://arm.koji.fedoraproject.org/status


In closing I would like to say, I do not think most administrators would care 
about RHEL6 or CentOS.  In fact they may prefer the modern up to date Fedora 14 
features.

Thanks

 Ay ay ay!
 
 This last 12 months have been frantic, as I've ended up biting off a
 ton more than common sense would recommend to chew. And then chewing,
 slowly, awkwardly. Good things have come out of the hard work of this
 year, but the XS has been delayed.
 
 One good piece of news is that I've helped deploy more XSs in the
 field, both in person and through this list. So I think we have good
 feedback on what to streamline and make easier.
 
 And I have a window of time to hack on it. So... the plan is roughly
 the same as it was in
 http://lists.laptop.org/pipermail/server-devel/2009-October/004139.html
 - except that I'll start drafting the build on top of F14.
 
 My actual plan is to have the packages for RHEL6 / CentOS6, which will
 give us a more stable platform. With less churn, I get to spend more
 of my limited time on interesting work :-)
 
 So -- going back on the traffic we've see in the last 24 months, what
 would you highlight? What have people asked for (that wasn't
 easy/trivial/possible)? What problems have we heard that were hard to
 diagnose...?
 
 cheers,

Re: os351 on XO-1 - Browse memory pressure

2010-11-02 Thread rihowa...@gmail.com
I just booted up my XO-1 running Dextrose os4dx2 in Sugar mode.
I revealed the frame and waited until the System Resources gauge had a happy 
face ;)
I started Browse. While starting the System Resources gauge pegged at 100% CPU 
and Memory in use 38%
Once Browse was fully launched the gauge indicated 8% CPU use and Memory n use 
40%. ( Steve - Cute icons in the gauge by the way ).

By the way while in gnome mode with this Dextrose build I managed to run 'yum 
install gajim' from terminal session. It ran slowly but I had a couple of other 
applications running.  I think the larger tmpfs helped yum run.  I had tried 
this previously with 10.1.2, but yum would crash even if run with no other 
applications running.

 been usable in earlier F11-based releases? Is it usable on dextrose?

Re: spectacular new XO-1.5 disassembly guides

Holt,

Nice set of photographs and narrative.
It might be useful to mention at the top of the document the type and number of 
screws.  At each step where a screw is removed or replaced that type and size 
of screw should be called out. 
Where it mentions cable disconnection and cable connection it should mention 
the type of latching mechanism used and how to manipulate it.

Page numbers would be useful as would a document revision identifier

Re: [Server-devel] Observations and question about http://wiki.laptop.org/go/XS_Software_Repositories

2010-09-28 Thread rihowa...@gmail.com
Martin,

It would make more sense for me to base this effort on F11 XS code even if it 
is experimental.  This will help find hardware dependencies in the code.
Is this the location you are referring to for the F11 XS 
http://fedora.laptop.org/xs/testing/olpc/11/source/SOURCES/ ?  If so I would 
rather clone from source control system so it is easier to give you any diffs 
back.
I know in the earlier versions of XS software there were a number of places 
that the arch was hard coded to an X86 variants.

 Hi Robert
 
 - that's excellent news! Ask on devel@lists.laptop.org -- AIUI, there
 is work afoot for F13 or F14 on ARM. I don't really know whether there
 are any usable builds...
 
 Thanks for the heads up, I've updated the wikipage -- fixewd up the
 git links (broken due to a change from gitweb to cgit) and added links
 to the F9 repos.
 
 If you look around the fedora.l.o server, you'll also find a F11
 experimental repo that might be of use.

 The only binary package IIRC is ejabberd-xs. And given that it's
 compiled against Erlang, it may well be portable bytecode.
Actually I remember there being an X86 blob in F9 XS bios-crypto tree

 
 There are also pyo files which should be portable across
 platform/cpu (but not across Python version).
 
 Is this the location you are referring to for the F11 XS 
 http://fedora.laptop.org/xs/testing/olpc/11/source/SOURCES/ ?
 
 That'll have tarballs. You are looking for the git repos, which are
 all under http://dev.laptop.org/git/

The XS related projects I see in http://dev.laptop.org/git/projects  all seem 
many months to years old.
Are you referring to trees under http://dev.laptop.org/git/users? If so which 
are the correct ones for F11 XS?


 
 I know in the earlier versions of XS software there were a number of places

 Help cleaning up bogus explicit arch welcome :-)

The make files have X86 archs hard coded in them

[Server-devel] Observations and question about http://wiki.laptop.org/go/XS_Software_Repositories

2010-09-26 Thread rihowa...@gmail.com
Martin,

I am back to working on getting the XS working on one of my ARM systems with a 
more recent Fedora version.
I am planning on using Fedora 12 for ARM.  (This is the latest Fedora ARM 
version I can find).
I was looking at http://wiki.laptop.org/go/XS_Software_Repositories to see if 
there had been any updated information posted to it.
I noticed that the links to the repositories are broken and the page has not 
been updated in a couple of years.
I was wondering if you could update the page with the correct links and maybe 
put a few notes on what source projects are needed to successfully bring up an 
XS and what is still experimental.

thanks in advance,

Robert H.

Re: [Server-devel] XS on Mac Mini

2010-03-02 Thread rihowa...@gmail.com

I am still planning on completing the port of XS to  ARM for the Sheevaplug /  
OpenRD Client. 
I recently  placed an order for a Guruplug Server Plus to add to my collection 
of Kirkwood SOC based devices.

The main delay I have had is waiting for an up to date kernel to become 
available for board implementations (mach_type) using the kirkwood SOC.
This is now available but not in the mainline.

The Sheevaplug has one USB, one SDHC, and one ethernet port.
The Guruplug ServerPlus has esata, 2 USB ports, 2 ethernet ports, wifi, 
bluetooth etc.
The OpenRd Client has sata  / estata  as well as 7 USB and SDHC and 2 ethernet 
ports.

Wad, I have been running a USB hard drive for months connected to a sheevaplug 
with no problems.
It is a matter of picking the correct drive and enclosure combination. 

I performed a code review of the XS source in preparation for porting.  I have 
to dig out my notes and compose an email to Martin
 with some questions and observations.  I hope to send the email to Martin this 
weekend.

 The Kirkwood ARM processor in the guruplug should be well
 supported by the current Fedora release --- this may be mostly
 a matter of moving to an F12 base.
 
 My main concern with the guruplug would be the external USB
 disks (overheating or disappearing).   The same hardware should
 be available in a NAS (networked attached storage unit), wrapped
 around a hard drive in an enclosure --- the Marvell ARM is a popular
 choice.
 
 We have good relations with Marvell, and have been encouraging
 them to get support for their ARM processors upstream for
 several years now.

Re: B R E A K T H R O U G H -- F11-on-XO1 has working video player

2010-01-27 Thread rihowa...@gmail.com
Mikus,

In http://lists.laptop.org/pipermail/devel/2010-January/027206.html I reported 
this but nobody seemed interested.  Also in that email I reported that Record 
in X11 for X0 still does not record video or sound correctly.
There is also problems with turning the radio on and off in sugar control panel.

As Steve Parrish has said he needs help as he has little time in the day to 
work on X11 for XO1.

 Having applied the ticket #9590 fix (adding 'Virtual 1200 900' to the

 my XO_1 systems, moving pictures work properly in F11-on-XO1 builds.
 
 
 Prior to the application of the #9590 fix I could not honestly recommend

Re: OLPC hardware: what if there was an SDR modem / chipset?

 dear olpc devel people,
 
 i've been doing some research and found a couple of companies with SDR
 R.F. front-end ICs.  one is 40nm and is so tiny that it will only cost
 about $2, mass-produced.  also thanks to being in 40nm, the speed of
 the (SoC / embedded) ARM9 core is so fast that it's perfectly capable
 of handling multiple protocols.  as you're no doubt aware,
 Software-Defined Radio has been full of promise for quite some time
 as The low-cost transceiver option, but it's only recently that the
 speed of embedded ICs has gone up enough and the geometry small enough
 to bring the cost down into the affordable range.
 
 key to making SDR work is of course having the software :)  but,
 i've found a company who already have GSM through EDGE; there's
 http://openbts.org and also of course there's the gnu-radio project
 which has produced part of 802.11, amongst other things.  ( but,
 remember: the nice thing about the 2.4ghz and 5ghz bands is that you
 don't _actually_ need to do 802.11, you can in fact just use the
 entire set of bands to do absolutely anything you want.  and, with
 SDR, you _could_ do anything you want).
 
 the neat thing about SDR is that the _same_ solution replaces:
 
 * a WIFI chipset ($10)
 * a GSM chipset ($12 lowest i've found in 100k+ volumes)
 * or a 3G chipset ($30 lowest i've heard about in mass-volume)
 * a GPS chipset ($6 and that's again an SDR solution,
   you need a DSP to translate; $12 for dedicated chipset)
 * a WIMAX chipset (haven't even looked this up, but estimate $20)
 * a DVB TV chipset (approx $5 and again that's an SDR solution)
 * an FM Radio chipset (don't know its cost, don't honestly care!)
 
 i repeat.  all those can be replaced with _one_ i repeat _one_ single
 solution, costing roughly... $12, if that.
 
 issues which need to be resolved:
 
 * paying for a minimum of 8 40nm 10in wafers (appx 5000 ICs per wafer)
 @ $0.50 ea, running the test vectors @ $0.75 ea, packaging @ $0.50 ea
 it works out roughly at $2.00 times 40,000.
 
 * creating the PCB with RF MEMS filters
 (http://en.wikipedia.org/wiki/RF_MEMS) and other assorted components,
 coax connectors for antenna, the remaining components are going to be
 somewhere around $10.
 
 * license compliance and Certification in the countries in which the
 final modem is deployed (remember that if frequencies other than
 2.4ghz or 5ghz @ greater than 100mW are used or 400mW in Hong Kong
 then licenses are NOT required)
 
 even with these issues to be costed out and resolved, i wanted to ask:
 
 * is the incredible low-cost and flexibility of SDR worth pursuing?
 
 * is the current Marvell 88688 proprietary firmware 802.11 blob
 _that_ acceptable / accepted?
 
 * is the possibility of being able to run an XO up a pole (or placed
 at the top of any tall building) and have it _be_ the GSM or WIMAX
 base station for an entire town or village and the surrounding
 countryside for miles around the kind of thing that is attractive to,
 and useful to the aims of the OLPC project, or not?
 
 also - one thing that also would help to have an answer to : if
 answers above turn out to be resounding yes, what's next?  who makes
 the decision?

Re: New release of F11 for the XO-1 - Build11

2010-01-17 Thread rihowa...@gmail.com
Sameer,

The fix is not in build 11.
I am resending the contents of the email minus the observation about midori, 
(as mention of midori seems to make the boys want to play with the bike shed 
instead of concentrating on the important tasks).  ;)

Some quick observations on  F11 for the XO-1 - Build11.

I have applied the Virtual 1200 900 fix from 
http://dev.laptop.org/ticket/9590 and the screen rotate button now works in 
both Sugar an Gnome.

Sugar Desktop mode:
I found with this build if I turn off  the Radio from the control panel I can 
not get it to turn back on.  Also the wording is confusing. It is unclear 
whether have the check box checked or unchecked turns off the radio.

The Record activity did not open correctly. It would exit immediately, until I 
applied the Virtual 1200 900 fix to Xorg.conf 
With the  Virtual 1200 900 fix applied Record will now open and I can take a 
photo and record a video. 
The video is very pixelated in Low mode though, and in High mode and Best mode 
Record video seems to only produce a still with some sound. 
Record's audio only mode does not seem to record sound.

Gnome Desktop mode:
I can turn the radio back on through Net Work Manager in Gnome.  This is after 
the radio is turned off in sugar where I cannot then turn it back on.  So the 
work around is to go into gnome and turn the radio back on.
I have not tried any Gnome applications that use a camera to see if it now 
works in Gnome

 Sorry it took a bit of time to respond but I've been on vacation and now am
 recovering from the flu.
 
 I released OS11 as a 1st build with the new buildsystem.  There are still some
 issues which need to be addressed but I wanted to get a new build with updated
 kernel etc out for testing.
 
 I did some local testing with powe rmanagement disabled by default and the
 issue persisted.  It only went away when I went into the control panel and
 manually enabled and then disabled power management.
 
 I truly wish I had the hours to devote to tracking down and fixing all these
 issues, however the $DAYJOB along with commute time keeps me away from home
 for 13 hours a day, and the $DAYJOB is not in the industry, where I could work
 on this on the side, but it does pay the bills.
 
 It is my hope to get the remaining issues addressed in short order so a final
 release can be made.  We do have a time constraint since F11 the base of our
 releases will go End of Life in June.
 
 I appreciate all the testing you and others are doing and would welcome any
 assistance in tracking down and exterminating these final few issues.

I am excited about developing a tool to help me develop other XO  
Activities.  When I shared my ideas with Adam Holt, he suggested  
that I seek a mentor, or a few partners to help me clarify my  
ideas, and increase the usefulness of the end product.   I am  
writing this to request such help.


As a programmer, I'm fairly new to python.  I started writing  
assembly language in 1975 for the terminal division of Hewlett-- 
Packard, which was soon to become the Personal Computer division.   
I only started python after I got my G1G1 in early 2008.


I'm fairly averse to re-inventing the wheel.  So I have been  
thinking of combining Activities that already run on the XO as my  
main strategy.


At this point I have hacked together Write, Terminal, and  Browse  
to all exist in a notebook under the Sugar toolbar.  I can read and  
write Activity.xo files from the journal.  So I've learned a lot  
from what is already written.  Whatever the final form factor, the  
work I've done up to now will not be lost.


At this point I'm debating whether to substitute gedit for the  
functionality of abiword.  Gedit includes many of the feature a  
programmer is looking for. It is extensively internationalized. It  
has a  python extension system that I think will make for easy  
integration into my application.


I'm leaning towards the structure of a remote debugger, even though  
the client and server will mostly reside on the same machine.  I'd  
like for the application to be insulated from errant client programs.


I'm having a lot of fun, and feeling much more productive than I  
did a few months ago.


I'd love to hear from a few people who are willing to help me  
perfect my ideas or have experience that could keep me from going  
down unfruitful paths. I've written a wiki page trying to pull  
together some of my ideas: http://wiki.laptop.org/go/

Daniel that is interesting.

My arm devices are booting directly on ubifs. One is running ubuntu  
( SheevaPlug ) and the other Fed 8 ( OpenRD Client). I am going to  
build Fed 11 this weekend for the OpenRD Client and then try and get  
the XS bits ported to it (but that is for a separate thread with  
Martin L.)

These devices use a special build of u-boot from Marvell to initiate  
the boot.

Wish I knew how to create drivers for OFW so it could boot from UBIFS.

 I think we are ready to do this without too much hassle - but first
 let's wait until someone has actually made and published a build and
 offered some kind of loose commitment to doing this on a regular
 basis.

 At that point, the relevant links are:
 http://wiki.laptop.org/go/UBIFS_on_XO
 http://wiki.laptop.org/go/UBIFS_initial_experiments

 I think the only remaining question from the earlier work was about
 the readings given by df -- but upstream justified that behaviour, so
 that is no longer an outstanding issue.

 The work will then be to:
  - modify the build system to build partitioned images (we need jffs2
 for /boot) -- I wonder if this will cause complications given the OLPC
 versioned filesystem layout...
  - modify livecd-iso-to-xo to make a ubifs filesystem for the root,
 and jffs2 for boot
  - teach dracut how to boot from UBI

Some good example scripts using RRDtool can be found at http://

Martin,

According to the http://fedoraproject.org/wiki/Architectures/ARM  
there is Fedora 8 and Fedora 10 port for ARM.  The OpenRD comes with  
Fedora 8.
I mentioned this at the OLPC-SF meeting this morning and we are  
adding it to our projects list.  I have 1 or 2 people at the meeting  
volunteer to help me with  this.  As a result of the positive  
responses I am going to order the ARM machine to experiment with.  I  
am not sure when the hardware will actually ship once I place the  
order.  A shipping delay will give me time to read some of the  
documentation on building Fedora for ARM.


What size hard drive do you recommend for the XS?

thanks

OLPC repository problems causing yum to time out

2009-04-05 Thread rihowa...@gmail.com
I was helping an XO user to resolve a problem with yum failing on her  
system.
After trying it on my XO I discovered that the OLPC  repositories are  
not responding. Hence yum errors out with a  timeout.
I can fix this for he,r but that leaves the problem out there for all  
the hundreds of thousand other XOs.
 Is this just a temporary outage?  If not could a dummy responder be  
set up to prevent the yum time out, as this is a difficult problem  
for naive users to deal with.

Re: New release8.2.1 build 801

2009-02-23 Thread rihowa...@gmail.com
  Release 8.2.1 build 801 fails to connect to my AP (linksys WRT54g  
L ) .  AP Icon starts to pulse then stops. Never connects.

Worked fine with build 800 and with build 800 updated with q2e32.

Re: [Testing] Wireless test results

2009-02-16 Thread rihowa...@gmail.com
I find 767,  with either q2e18 or q2e24, connecting to a WPA AP  
succeeds 100% of the time for me using a Linksys WRT54g L.

  With OFW q2e32 I have seen the network connection die. Seems like  
the stack is dead.  I assume it is the marvell driver that is  
delivered with q2e32.  My other XO running 767 with q2e18 maintains  
its connectivity.

 Hi,

 Last I checked, it was either the firmware or the kernel changes
 that did it.  I posted my findings to the mailing list in the past
 two weeks.

 I think your findings actually say it was either the firmware,
 kernel,
 or something else altogether.  It'd be good to downgrade both at
 once,
 but still on candidate-800, so that we can check that at least *one*
 of
 the two is the problem.

 I should be asleep, but instead have been zigzagging through old  
 http://xs-dev.laptop.org/~cscott/xo-1/streams/staging/
  staging builds testing WPA and the dialogue cancel dance for the
 last 4hrs:

 790 working
 4 working
 5 working
 6 working -
 7 intermittent
 11 intermittent
 15 broken
 800 broken

 Intermittent means it can occasionally associate with a WPA access
 point with no cancel dance, but usually I had to dance. Broken  
 means I
 had to dance every time.

 One thing I noticed when testing the working 4, 5 and 6 that may  
 help,
 is that if you do naughtily click an already connected WPA access
 point you'll get back to one round of the WPA cancel dance. If you
 make sure you first  select 'disconnect' then click the AP again, you
 get correctly re-associated, no dance required. This suggests that
 clicking a connected AP should either do NOP, or should at least
 disconnect properly before trying to connect again.

 The sound you just heard was my head hitting the pillow :-)

 I reported this before with build 26 I believe, but it might be of use
 to point out again. Also on 800, the ability of the XO to connect to
 an AP have been greatly increased over 767. At the moment connecting
 to a WPA ap succeeds one in two times. On 767 it varied from 1 in 5 to
 1 in 10 to 1 in can't be bothered to try and connect to the fr!@@n
 access point. I already supplied some logs, but if you'd like some
 more specific testing output of our setup, I'd be happy to supply it.
 Just tell what you want to know.

Re: OLPC upgrades

Those software gauges tell you what ever 'version of the truth' the  
author wants to tell you and make you feel happy about your device.
To perform power measurements reliably you need to instrument with a  
good quality physical voltmeter and ammeter.

 What do those same gauges tell you about an XO under F10?

 unless things have changed, those same gauges won't exist on
 the XO -- we don't do acpi.

Re: XOs with no sound

2008-12-30 Thread rihowa...@gmail.com

I have seen this problem when the alsamixer settings have become  
messed up.  Seems like there are one or 2 processes that occasionally  
write to the alsamixer config file.

You can alter the settings by running the graphical program /usr/bin/ 
alsamixer  from the terminal.  There is also a command line program / 
usr/sbin/alsactl but being late at night I can't remember the syntax  
off hand.

 Hi

 The sound of 5 of our 100 XOs doesn't work anymore.
 The hardware test is okay (sound works), but all the sugar  
 activities I
 tested (Scratch, TamTamMini, Speak, Gcompris) don't have sound.
 Rebooting the XO doesn't help.

 I checked the sugar log files and /var/log/messages, but couldn't find
 any sound related warnings or errors.

 We are running build 767, but I have seen the same problem with build
 708 (but not that often).
 Reinstalling the OS solves the problem, but I would prefer an easier
 solution.

 I checked if such a bug is reported, but couldn't find a ticket (the
 sound resume problem of ticket 6201 is normally solved with a reboot).
 Since I don't know how to reproduce the problem, I would like to
 localize it before opening a ticket.
 What can I do to localize the problem (e.g. low level sound tests)?

 Is it possible that running out of battery while playing sound can  
 have
 such an effect or could it be related to the resume problem of ticket
 6201 (we had that problem very often with Scratch when the  
 experimental
 power management was switched on )?

Re: Jabber client activity

Mildred,

Chat is a jabber client.
Also other people have gajim and or pidgin running okay and no  
problem with saving configuration.

 Hello everyone,

 I'm new here, and I came interested in the OLPC project because it's a
 wonderful computer, very well integrated, and I just had one via the
 European G1G1 project. And now, I thought I could contribute :)

 I wanted to know if there was any project of creating an activity that
 would be a jabber client. If so, could I help, where is it? And if  
 not,
 perhaps I should start one.

 I just tried to run gajim in sugar,  but it seems because the $HOME  
 gets
 defined in a sandboxed environment that is erased each time, so I  
 can't
 keep the configuration :/ On the other hand, I think that writing from
 scratch a jabber client would require much work, and time I don't  
 really
 have. What do you think is appropriate?

 Thanks :)

Mildred,

In the Control Panel, select Network and then in the Mesh server  
field put the server name.

 I guess, but I have absolutely no idea on how to configure where  
 you put
 your jabber id and your password. So far, I thought it was only useful
 inside the mesh networking.

 By the way, I just created a Gajim activity inspiring myself from the
 Firefox activity, and it seems to work even if sugar integration could
 be pushed further. If anyone wants it I think I can put it somewhere.
