Maybe automagically move and delete some logs, etc to another storage, like
USB stick?
Putting in more storage on non SD may change the calculation kind of like
/tmp or use livecd persistent partitioning schemes...
/WAG
Removing packages like java, some fonts documentation, etc may help
temporarily but also may make the system inconsistent and unbootable...

Re: using laptop charger

Sounds evolutionary to use netbook power on XOs

 However the original poster wanted to avoid carrying two adapters, so
 a replacement adapter probably won't meet his requirements unless it
 can do both jobs.  ;-)

 There are switchable voltage third-party laptop adapters, but the
 switches on them may not be rated for daily voltage changes.

   I don't recall the actual voltage (Richard may remember), but I
 think

   So it might work, or might not.
  
   Instead of using a resistor, you might use two or three large
 diodes

 drop.
   Pick the diodes based on the maximum current 1.85A (usually double
   that), and the power that will be released as heat; P = V x I,
 where V
   is 0.6, and I is not to exceed 1.85A, so 1.11W minimum power
   dissipation.  Place them in a way that does not hold the heat in.

   p.s. if you find one diode does what you need, then add another in

Interesting. If you did in fact reflow anything then it was probably due
to the poor temp regulation of your toaster oven. The solder in the XO is
lead free and melts a higher melting point than 385. I don't know the exact
formulation that Quanta uses but most lead free formulations melt at 215C
which is 419F.

Thank you for being the first person to offer actual data on this. Since I
baked it at 385, or thought I did, if in fact the melting point is 419, then
I didn't reflow the solder at all. I need to get an independent oven
thermometer to stick in there if this turns into an habitual endeavor.

If you actually didn't reflow anything then the forces from the large
thermal gradient may have been sufficient to push the cracks back together
enough to work again. (Sort of the same thing that happens when you test by
pressing on the chip hard to see if it boots)

A production line oven uses a soldering profile. Pre-heat, then a brief
spike over the melting point and then a cool down.

If you do a search for lead free soldering profile you will see loads of
information on various profiles. Picking something that closely matches one
of those profiles will give you the greatest chance of success.

Good to know. Since this isn't like tempering steel, if something goes
wonky in the future, I can examine what production lines do and try to
emulate that as best I can. The wikipedia entry on reflow ovens wasn't very
detailed, but I didn't know what else to search for so I just hauled off and
did the best I could. I got most of my info from a message board where
folks put their HP laptop mobos in the oven.

As James mentioned if you forget and bake the RTC battery then there is a
very high probability it will explode. At my previous job we once used old
computer motherboards with thermocouples attached to tune our profile and we
forgot to take out the RTC battery. It exploded but thankfully it was while
it was inside the oven and no one was injured.

Oh, yeah, I made sure to remove the battery. And anything else that might
explode, catch fire, melt, or otherwise make a wicked mess.

A couple of hours ago, I baked the second XO 1.5 motherboard and yep, it
booted after that. I took tons of pictures this time. I'll post a writeup
with the pictures in the next few days. At this point I feel like Julia
Child. If Julia Child put circuit boards in her oven.

And no, this is definitely not for the typical user, but hey, on Friday I
had two dead XO 1.5's and now on Sunday evening I've got two working units.
No idea on the longevity of this fix, but OLPC is all about experimentation,
right?

Many +1 on a job well done. Indeed this project is about
experimentation what an incredible group of crazies we have here!
There are no boundaries to learning. Keep plugging away! I will now go

 Peter,

 I guess that is one way to see it, but there are other perspectives.

 As 2.9.x represents the first development release of what will become 3.0,
 now is the ideal time to begin looking at it as AbiWord is OLPC's word
 processor of choice on the GNOME boot side and word processing is an
 important activity to deployments.  Better to engage early and have the
 opportunity to shape the direction of further development than to show up
 late to the party.

 Some of the key features now present in the 2.9.x series represent the
 culmination of work that was done collaboratively between OLPC and AbiWord
 to develop the Write activity a few years ago.  These features include
 support for collaboration via Telepathy (Jabber/XMPP), so it's release an
 achievement in which OLPC can share some pride with it's friends from
 Collabora who contributed to making this possible.  Improved support for RTL
 languages like Arabic and Hebrew made substantial gains through work on
 Write and is a feature of importance to some of OLPC's deployments.  The
 experiemental EPUB authoring plug-in has the potential to greatly facility
 sharable content creation on the XO.

 Or I suppose you could ignore it until 3.0 ships and then figure this stuff
 out in a rush and be too late to have any influence or further leverage the
 historical ties between OLPC and AbiWord that have so far proven remarkably
 beneficial to both communities, YMMV.

 But at those prices why aren't they giving you a batch and hoping someone 
 hacks on the MicroSD, adding expansion RAM + SSD and fit it in a tablet type 
 case.

 Its not expandable for the likes of RAM etc. You need to add those at
 manufacturing. 512Mb of RAM (or even 256) and 3 rather than one USB
 port would make it usable (keyboard, mouse, network). A form of
 networking even more so. But I suspect that would make it closer to a

 When XoPhoto loads, it checks for at least 10 images, (mime_type

 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.


 The journal images can be deleted pretty easily, when the user is done with

 and then empty the trash.

 There is no trash in Sugar, its a dropdown menu in Journal to delete.

So I'm reminded of my first handheld computer,
and beaming between friends, my contact information,
like a business card, and sharing applications/ activities
by beaming them to someone in the proximity
by IR.

So fast forward to the WiFi age, and several
friends within a classroom or after school program/
activity, or passing notes in class ;-/

Not everyone in the proximity is the intended
audience for the note or information so some
security might be in order (lest the teach get
the note), just as not every acquaintance is
a friend, but given more and more contact
(connection counts?) and less arguing
leading to ombuds/ sent to the principal's
office, or whatever.

Also to beam to mother ship OLPC/SugarLabs/
Donors/ Remote Family/ Global Village
to put on the Refrigerator art work
and other creations by kids.

I realize not all cultures focus around

Re: open 80211s on XO 1.5

2009-10-30 Thread DancesWithCars

I'd said to lots of people that the XO
uses 802.11s mesh networking
and eventually ran into someone rather
geekie and otherwise impressively knowledgeable
who corrected me that they didn't implement the
whole standard (and people here say draft).

The Marvel driver is said to be closed source,
and RMS didn't like that, all of course
rumor, and another rumor that the
driver was open sourced.

No rumors on the XO-1.5 yet, which
is a shame.  Even as hype and pre-release
getting a buzz going would be nice.
I don't have one, so can't test it to
find out. Computer are supposed
to be a Science, or so Knuth
is credited by the ACM for
helping to make that happen,
documenting the fundamental
algorithms and all...


There are other mesh networking
and someone once said to me that
the 802.11s isn't that special
that mesh OLR or somesuch
protocols have been around for
some time, but I'm guessing
the XO is one of the bigger
(~1 million XOs out there somewhere)
publicly known implementations
in that arena.

So if someone / laptop.org
wants to set the record straight
and give definitive info, that would be
great...

 Under a tree, using mesh networking is pointless (unless, I suppose,
 it is an extraordinarily large tree).  Mesh networking allows packet
 forwarding from node A to node B, where such nodes cannot normally
 communicate with one another directly.  Packets are forwarded through
 node C, visible to both A and B, or through multiple such intermediate
 nodes.  If A can communicate with B, mesh is neither helpful nor
 advisable.  It just confuses things, which is the problem we see with
 large numbers of children in a classroom.  The mesh efforts to keep
 track of how to get from A to B can quickly saturate the RF spectrum
 with a lot of unhelpful traffic.

 I can't tell what it is you're doing at your meetings when your users
 all use mesh.  At a typical in-person meeting, you have a number of
 people using XOs all in the same room.  Any XO in the room can
 communicate over WiFi directly with every other machine in the room
 (except in extremely unusual circumstances, or too many attendees
 wearing their tinfoil hats).  There's no need for or value to mesh
 network - A doesn't need C to forward packets to B because A can see B
 directly as another ad hoc node.

 If there's an AP providing routing to the Internet or other external
 networks, there's no mesh required there, either, presuming that each
 XO can communicate with the AP directly.

 I can't answer your question about whether those scenarios use ad hoc
 networking because I don't quite see what it is the users are doing in
 those scenarios.  What (lowercase) activity are users engaged in when
 you say they all use mesh?  What do you think they would be unable
 to do if they all stopped using mesh?  Thanks for the info.

Thank you. And yes I'm conflicted.

Not that I plan on hacking it,

 P.S. The 802.11s draft standard has certainly been implemented on other
 devices; no one suggests it is unique to the XO-1.  What is special about
 the XO-1, AFAIK, is its ability to continue to operate as a mesh node (or
 MPP, mesh portal point) and forward packets while the laptop is otherwise
 shut down.  The fundamental limitations on the utility of 802.11s in typical
 XO-1 scenarios, however, limit the value of this unique (I think) laptop
 feature.

Re: Sharing files among several XO

2009-10-28 Thread DancesWithCars

The term mentality is not an software Activity
but a general construct (mental model?)
within our conditioned
(other computer using) brains.

I should have been more clear with possible
cross language audience, though I started using
psychology jargon, a little mixed with plain
[human] language.

The instance of the OLPC presentation
I heard it was an impromptu fill in for a
XO 1.5 demo at the Gallaudet.edu campus
during the ClassActs book sprint.

And I have trouble with English as a dyslexic.

 2009/10/28 DancesWithCars danceswithc...@gmail.com:
 Good question, I that some one from Cambridge
 said you could share files, but maybe that is from
 our other machine peer to peer file sharing mentality,
 and not really implemented on the XO,
 or did I miss something?

 Even the files term is a little shakey,
 as a Journal Activity instance
 may not be the same as we usually think
 of a jpg, .txt file , etc. as the sugar
 wraps activity metadata around the
 instance?

 So, I will also be anxious for the solution...

 I tried the Distribute activity but it proved to be unreliable.

 I am using XO with latest stable Sugar updated from olpc-update

 I'm very excited to hear about this project, and I hope you'll keep us
 updated with your progress.  Anything that makes Sugar a better
 self-hosting development environment is tremendously valuable for us.

 At this point I'm debating whether to substitute gedit for the functionality
 of abiword.

 IMHO, your best option is to use gtksourceview [1].  This is the GTK
 source code editing widget that is used by gedit.  gtksourceview provides
 syntax highlighting, line numbers, and undo/redo functionality.  You can
 see it in use in Sugar in the Pippy source code [2].  Unlike gedit,
 gtksourceview is guaranteed to be present in any Sugar installation.

 Good luck!
