 http://oficina.paraguayeduca.org/~crodas/0045-Fixed-Out-of-memory-error-on-XO-1.patch

Can you add an explanation?

It doesn't look correct to me. Here's my understanding:

The task of this function is to create a new offscreen memory allocation
of a certain size.
The function goes through the list of existing allocations, looking at
each entry. It calculates how much free space there is inbetween one
entry in the list, and the next one. If there is enough free space, the
new allocation can be inserted at this point. Otherwise, we have to
carry on iterating through the list.

In that specific section of code, gap is computed, in 2 stages, to be
the amount of bytes inbetween the list entry currently being examined
and the next one.

if (ptr-next == NULL)
gap = pGeode-offscreenSize + pGeode-offscreenStart;

else
gap = ptr-next-offset;

This is the first step. It is setting the gap variable to the absolute
address where the next allocation starts. In the first branch, we have
reached the end of the list, therefore our upper bound is the top of the
offscreen memory.

In the 2nd branch, there is a following member in the list, so our upper
bound is the address of where that memory allocation starts. And the
offset variable is always absolute, so this is the correct calculation
for the upper bound.

As the 2nd stage of the calclation, the lower bound is considered (the
end of the allocation currently being examined) to produce a final value
of gap that represents the number of bytes inbetween the 2 consecutive
list entries:

gap = gap - (ptr-offset + ptr-size);

To me, everything looks correct before your patch. What am I missing?

Thanks,
Daniel

the old saying is 'never underestimate the bandwidth of a station wagon 
filled with tapes'


with current hard drives (1-2TB each), don't underestimate the bandwidth a 
a suitcase on a mule.


when I last ordered drives in bulk I got 20 drives in a box ~6 x 12 x 
18 packed for shipping.


one round trip a week of 20x2TB drives is 554Mb/sec, or 69MB/sec. To 
simply transfering the data to/from the drives would require two drives 
reading continuously all the time at each end to read the data being 
received and two drives writing continuously to write the data being sent


now, this isn't taking into account the horrible latency in this network 
connection ;-) but it means that if there is much of any transportation 
the data can be moved around to make it available.


this won't work for interactive services, but it will work for e-mail, 
data requests, etc.


now this is obviously overkill and beyond what is reasonable to try and 
implement for one data link in the wilderness, but this sort of thing is 
being done today, in first-world countries to move large scientific 
datasets around.


20 drives cost ~$4k, shipping them 2nd day will cost ~$200/shipment 
so shipping this 15 times in a month is ~$3k and result in ~2Gb/sec in 
bandwidth. you won't get 2Gb/sec in connectivity for this price (assuming 
that you can get it to your location in the first place)

I would take it all with a large dose of salt. They are design
drawings. To use a quote from Nicholas Negroponte that Engadget list
in their article [1] Sure, if I were a commercial entity coming to
you for investment, and I'd made the projections I had in the past,
you wouldn't invest again, but we're not a commercial operation. If we
only achieve half of what we're setting out to do, it could have very
big consequences. so they are concept and could all go the way of the
XO-2 between now and 2012. They look cool none the less and with the
supposed launch of a tablet in Jan with a Pixel Qi screen may not be
that far away.

 Can you add an explanation?
 
 It doesn't look correct to me.

You are right. It's not correct. The allocation algorithm is OK as it
is. We got a wrong understanding of it and since our change made totem
and cheese work (because memory was returned - even though we might
probably be stepping on someone's else memory) we decided to share the
results. 

The linked list which keeps the count of used regions seems to be
manipulated correctly so no problem there. We are actually running out
of offscreen memory. 

After much looking at the code I went back to X's log and I saw an
interesting difference between 8.2 and F11.

8.2 (old geode driver):

(II) EXA(0): Offscreen pixmap area of 11208320 bytes

F11 (new geode driver):

(II) EXA(0): Offscreen pixmap area of 5829856 bytes

I wonder why there is a 3MB difference. Ideas?

Re: XO-3 official

 I would take it all with a large dose of salt.

Also, as usual, the left hand at OLPC doesn't know what the right hand
is doing.  The press release isn't on www.laptop.org, nor is there
anything in www.laptop.org or wiki.laptop.org about the XO-3 (or even
the XO-1.75).  The press release (which is on Business Wire) links to
30 megs of nice publicity photos -- which nobody can download any more,
because they're on a foolish hosting site that has reached its
download limit.  Etc.

My sentiments exactly.   The press release
was solely from the industrial designers, with no
feedback nor approval from the team that
will actually have to make their dreams
become reality.

 holding the power button for about 2 seconds, brought the system back
 from sleep . Is this normal or expected? It does not seem right..

 Intentional.

 6) There is no shell activity. Is that an intention to hide the
 filesystem?

 Intentional, yes.  It is only hidden.

that was dumb of me I forgot not every activity is a favourite :)

Brief testing of OS10 (F11 for XO-1)

2009-12-23 Thread milan zimmermann
Hi,

A few observations running  OS10 on XO1.0 with latest XO1 firmware:

1) After about 10 minutes (did not measure time exactly) , all input
from keyboard and keypad stops. Interestingly, mouse plugged into USB
still works. I assume this is because of the Power saving (first of
the 2 options) is on. But:

2) By default, Power saving first checkbox is on. But it does not
persist when set to off.

3) Interestingly, recording sound in Etoys works (freezes on OS43 and
higher on XO1.5, see https://dev.laptop.org/ticket/9724).

Actually I think the hands are all doing a very good job.  It's the head
that needs attention.

One thing does interest me however. the comment it plans to open the
architecture of the device to allow any other PC maker to take over the
project. 

Is this in the realms of possibility for the XO-1/1.5?  Specifically,
would OLPC allow a 3rd party to manufacture a system with their own
motherboard using the XO-1 case, battery and screen.  Perhaps with a
colour change to make it distinctive as another product.

Re: [Server-devel] Various / PDF resources in Moodle

2009-12-23 Thread David Leeming
Martin, 

Regarding pushing activities, I agree that putting them on the XS to allow
the users to manage themselves is the best way. If a teacher wants to make
sure that all have it installed, they can always create a folder with the
activity uploaded to make it unambiguous. A Todays files folder would be
useful, with the teacher directing children to it using sharing Bookmarks
(Browse), so they have only to join the shared activity and then click on
the Bookmark - 2 clicks to the resources for the lesson.

3 questions, 

(1) what happens if the version on the XS is different (higher or lower)
than a version one already on the XO? Do you get duplicates or does the
latest downloaded/run version preside? 

(2) how can one upload an activity to a folder on the XS from an XO?

(3) What is the location on the XS of site files and course files, in case I
want to load stuff manually?

Here is a combined report on several related non-critical issues. 

Firstly, I took note of your suggestion and updated my four XOs (2 B4s and 2
C1s) using 802/2QE41 and the latest version of the activities. I upgraded
all of them using the same memory stick using the fresh install method (four
game keys on boot). So they should have been identical software wise.

I discovered two issues in this process. 

(1) It's difficult to know which are the latest stable versions of
activities as the OLPC and Sugar activities pages differ (unless I missed
the small print). Sugar has more advanced versions. However, I noted that
you referred to Browse 102 which is the current version on the OLPC wiki for
that activity. I decided to use the OLPC wiki Activities page for all the
G1G1 core activities and the Sugar site latest versions for the rest. I
have yet to test them all but all seem OK so far. SO, I am using Browse 102
and Read 56.

(2) At risk of seeming to make a fuss out of nothing, this issue has the
potential to cause a lot of confusion and time wasting. After noticing some
activities and collections failed to start or appear, I suspected that some
of the downloads were incomplete. This was confirmed when I looked at the
shell screen that appears at the stage when activities are installed one by
one. If there are errors, the activity is shown with an exclamation mark
rather than a plus sign. I found several of the files were not installing
properly. This I found to be because they were incomplete. The downloads had
terminated partway through, however with no indication of anything amiss. I
used a download manager and re-downloaded the ones that had failed to
install. True enough, they now all installed and I can see all the
collections, for instance. The issue here is that in countries where there
is unreliable connectivity (slow with outages, as is the case here in
Solomons) this will be something people will experience. Can the downloads
be provided in a more reliable way so that one knows that one has got the
full file? Or otherwise recommend people to use download managers. 

Now to the other issues.

(A) PDFs uploaded to Moodle folders always open in the Rainbow-Daemon
dialogue when you left click on the links. If you go to hyperlinks on HTML
pages either in my local public folders or out on the net, a PDF file always
opens in the Browse version of PDF reader when you left click on it. In all
my tests it is fully reproducable using both B4 and C1s. I would prefer them
to open in Read activity, which has but it's not a huge problem, they are
very similar. One can also Keep and then open from the Journal. But why the
rainbow-daemon window? 

Thanks!

Thanks.

Orange flag right there: Browse-98.xo? Get Browse-102.xo from
http://wiki.laptop.org/go/Activities/ (and I think that will fix your
B4s that don't auto-authenticate ;-)

So

 - upgrade Browse, retest!

 - are you using Squid? If yes, switch it off, retest...?

 - other websites serving PDFs -- test one from
http://wiki.laptop.org/go/Category:PDF

 Where do I register bugs, sorry I should know that. Let me know and I will
 do it if you confirm you can replicate.

http://dev.laptop.org/ get an account there. It's a rite of passage
;-) If you want to draw more attention to the usability issues for
future releases of Sugar, also get an account on
http://dev.sugarlabs.org/ and file a bug there.

cheers,

Were these downloads done with Browse on an XO, with Software update on
an XO, or on another system?

A partial HTTP download normally occurs if a connection is interrupted.

HTTP has a feature to support resuming from the point of interrupt.  I'm
not sure if Browse or Software update are doing this.

HTTP has a feature for detecting partial downloads, but the client side
(Browse, Software update, etc) has to choose to use it.  The HTTP header
sent by the server contains a total length value that can be checked
against what is received.

Both of these features may not work if the internet service provider
fails to take the care to support them.
