Re: Rainbow 0.7.12 Announcement

> in order to solicit more widespread testing

Installed it manually (yum) on my G1G1.  Of various Activities to 
which I previously gave "special dispensation" from Rainbow, three 
now launch from the activity ring without needing that dispensation 
-- Develop, Sonata, and Opera.  Activities I tried for which even 
the new Rainbow shows error exceptions were 'TuxPaint' and 'KuKu'.

Rainbow 0.7.12 Announcement

[Michael Stone]

Folks,

I've released a new rainbow, version 0.7.12 into Joyride in order to
solicit more widespread testing of some changes that I'd like to
incorporate into our next release. This version has some tasty things
like
 
 - delayed rainbow startup (which will allow X to win the rainbow/X
   startup race [#6797] more frequently) contributed by Blake Setlow, 

 - "fail-safe" handling of preloading-related import errors, and
   
 - a compatibility patch which makes $HOME writable by activities by
   setting $HOME and $SAR/instance equal to one another.

The final patch requires that we diverge from the version-1-spool-format
used by previous versions of rainbow. User applications which
automatically always follow symlinks should require no changes; however,
prior versions of Rainbow's uid garbage collector will complain noisily
at boot and will probably be unable to collect uids allocated by
rainbow-0.7.12 or later. Prior versions of Rainbow may become unable to
launch activities which have been launched by rainbow-0.7.12 or later.

If either of these issues sound like trouble, we can bump the spool
format version number (i.e. start locating version 2 spools in
/home/olpc/isolation/2/), provide a migration tool, and propagate the
change throughout client software. (The only software that I know of
which cares is the DataStore, and it's easily patched.)

Comments?

Michael

P.S. - Further review of the diffs from the rainbow-0.7.11 to
rainbow-0.7.12 tags in the security repo is quite welcome. Please don't
be shy if you see ways that this code can be improved!

There is no school server around, so the go to simple mesh by default.

Following up on my post...I upgraded my G1G1 from 656/Q2D07 to 703/Q2D14
and updated the activities using Bert's script. I re-ran Michael's 
pen-tablet script. I still didn't see the pen-tablet feature working in
Paint, until...I applied a lot more pressure than I had anticipated. The
cursor moved! So, I guess the pen-tablet script makes it work, but the
amount of pressure needed is a lot more than what I would apply to my
Nokia 770 or 810.

Is this expected?

The idea is that the bot in projectdb.olpc.at reads the Talk: page  
about the project proposal on the wiki.l.o.
That way - people will be able to talk and discuss a project  
application on a community level. Let's say in a mediawiki style.
Then these comments get fed back into the projectdb and the persons  
who really have the "vote" bit set can decide about a project proposal.

But the main concern so far was: 1) do we get the data in correctly  
and 2) can we export it to B* ?

These community features can be implemented in hack sessions on  
weekends usually.

Re: 15 computer science collegians looking for a project

[Jim Gettys]

Specifically, the intent of the developer program is to support
development: it is not a back door way to get machines for small trials.

In general, it is in support of individual's needs (one or a few
machines), though we'll also consider a professor's request for a class
they are teaching, or a researcher wanting a (small) bunch of machines
for working mesh software.

What we don't want to see are "front men" who claim to be supporting a
set of developers, and acts as a gatekeeper for access to systems.

For example, if you have a set of 10 developers, I'd expect there to be
10 individual requests (for possibly significantly more than 10
machines).  If someone can't be bothered to fill out that minimal
information, they are unlikely to actually do anything with the machine,
and we've seen instances that appear to be individuals trying to use
their navigation of the developer program to further private agendas.

And yes, Aaron's nice work enables a group be able to evaluate these
requests (and that group be community based, not OLPC employees).

Awesome! If you do take up this unpleasant, though critical task
here are my suggestions:

Like I said before, when a user reports that "the network does
not work", this may be due to a whole lot of reasons. Being able to
consistently identify which part of the "network stack" (firmware,
driver, NetworkManager, presence stack) is malfunctioning is not
feasible anytime soon, so we better make sure that each individual layer
is this network stack has been thoroughly tested. I would suggest doing
so in two dimensions: scalability and stability.

Scalability: Making it work on 5 machines is one thing, making
it work on 50 is another! Please test on as many machines as possible.

Stability: Similarly, we should aim for at some 5 hours of
continuous and stable operation.

We currently do _not_ meet these requirements and from an
activity point of view, the network look like an  omelet rather than
distinct yoke and white!!!

Bill,
That's great!
Would you take a look at  http://dev.laptop.org/ticket/6237 and check if
this is something that can be done within your time frame?

Cheers!

Re: Mesh testing

[Ricardo Carrano]

Pol,

I suggest you switch to 22.p10 which fixes a bug in 22.p9.
But you should not use any firmware later than 22.p6 with stock kernel
(because of the multicast filter, #6818). It surprises me that you are able
to collaborate at all.

[Jim Gettys]

I'm told the new process through the web site the OLPC Austria folks set
up, referenced on the developer program page, has been made to work.
(my thanks to them for their great work)

Still one manual step at our end, but not the fully manual, error prone
process of before.

Awesome! If you do take up this unpleasant, though critical task here 
are my suggestions:

Like I said before, when a user reports that "the network does not 
work", this may be due to a whole lot of reasons. Being able to 
consistently identify which part of the "network stack" (firmware, 
driver, NetworkManager, presence stack) is malfunctioning is not 
feasible anytime soon, so we better make sure that each individual layer 
is this network stack has been thoroughly tested. I would suggest doing 
so in two dimensions: scalability and stability.

Scalability: Making it work on 5 machines is one thing, making it work 
on 50 is another! Please test on as many machines as possible.

Stability: Similarly, we should aim for at some 5 hours of continuous

Re: 15 computer science collegians looking for a project

[Kim Quirk]

If you have applied to the developer's program a few months ago, please
check to see if your application was transferred into the new system:

http://projectdb.olpc.at/

If it is not there, I'm afraid you will have to apply again. The idea with
this new system is that there is a community who will help evaluate the best
uses for laptops. Please note that this program is for single or two laptop
requests, not quantities, so if you request quantities of laptops, it will
probably be refused.

SJ, Aaron,
Can you provide an overview of how the new system works? How applications
get reviewed and how often ship orders will be sent out? How people get
feedback on their request, etc?

Thanks!
Kim

Out of the 50 nodes (over a period of time of 6 hours), 8 nodes
"decided" to take msh0 down, half of which did not come up again
(NetworkManager?).

About 18 out of 50 nodes (not including the previous 8) for some reason
stopped being reachable from the rest of the network, although their
network interface did not seem to have been reset. Restarting the
NetworkManager seems to fix the problem.

Is anyone still maintaining the NetworkManager? It seems to me that the
NetworkManager chooses to restart msh0 sometimes. Is this true? Does it
go so far as to reload the firmware?

network interface did not seem to have been reset. Restarting the 
NetworkManager seems to fix the problem.

Is anyone still maintaining the NetworkManager? It seems to me that the 
NetworkManager chooses to restart msh0 sometimes. Is this true? Does it 
go so far as to reload the firmware?

Re: 15 computer science collegians looking for a project

[Jim Gettys]

I checked this morning now that I'm functioning again; the developer's
program should be moving again, and volumes available should be much
higher than before mass production (particularly if you can tolerate the
Arabic keyboard, where we have stock that can be redirected right now).

Sorry to be slow to respond; I came down sick with a nasty cold bug
last week on top of recovering from surgery.  I'm only now wading
through 1200 back unread mail messages.

That's not necessary, actually. sugar-jhbuild update itself on build.
(as I announced on the sugar list, because of major refactoring a
clean checkout of sugar-jhbuild was necessary to get things working
correctly in this case)

What's up with sugar-jhbuild?

[James Simmons]

On my SUSE box I have a sugar-jhbuild installation that is not fulling 
functional (Browser activity doesn't work, Salut doesn't work).  I've 
been trying to keep sugar-jhbulild up to date in hopes of someday 
resolving this problem.  For the past week I get this when trying to

I can still use Sugar on SUSE as before, though.

It looks like there is a fallback for checking the IP address if
Network Manager is not detected on the D-Bus system bus. I've never
tested it though.

Wait a second. Presence Service requires NetworkManager instead of

Presence Service will only attempt to connect to a jabber server if it
sees Network Manager get a valid IP address. Without that, you only
see the salut / link local collaboration, which works for <10 XOs on
the mesh.

Schools require jabber servers.

Let go of that dream. Marvell is just giving excuses for
why they won't release the rest of the code. The true
reasons are not public, but likely: the code is a buggy
piece of crap that Marvell sees as being valuable IP.

That dream has already cost us dearly, and I think it
