actrd.zip should only be loaded when a laptop is being booted
securely, when it does not have a developer key, or when the ❌ (cross
mark) game pad key is used to force secure boot when in non-secure
mode.  Purpose of actrd.zip is to obtain a lease or deny use of the
laptop.

http://wiki.laptop.org/go/Firmware_security has more details, as does
the kernel git repository directory olpc/.

What was the warning?  If it goes past too fast, you might be able to
catch it with a serial console, see
http://wiki.laptop.org/go/Serial_adapters

Debug it.

Does your kernel have jffs2 support enabled?

Look at the code being run.  You'll find it in the OLPC dracut source
repository.  http://dev.laptop.org/git/users/quozl/dracut-modules-olpc/

Use an SD card or USB drive to boot the laptop and look carefully at
the jffs2 filesystem.

http://wiki.laptop.org/go/Tiny_Core_Linux
http://wiki.laptop.org/go/Cheat_codes

Also, we have several different actrd.zip files, make sure you are
using the right one for the kernel.  It should be in the kernel RPM.

 Hi, Adam

 George Hunt's image installs Moodle 1.9.5+ (build 20090910). There was
 a major change in Moodle between 1.9 and 2+. So far as I know, XS has
 always used Moodle 1.9.

No question that landing Sugar more or less everywhere is a goal.
Sometimes the means of doing so can be a litttle more complex that
jsut installing a build on an XO (e.g. stuff like Sweets
Distribution).

I find it hard to keep track of all of the methods and approaches
tested / employed, but I would hazard to say that an install based on
the Sweets Distribution would be Sweetie Pi.

need help with 'fix clock' problem...

2010-05-24 Thread F Young 
Hello!

I purchased the very first versions of the XO laptop through the buy
one give one program in 2007. Although we used several right away and
they worked without any problems...we stored 6 of them away and
recently discovered that none of the screens turn on when powering up.
It appears to be the fix clock problem and since I live in
Kyrgyzstan it is too expensive to ship back to the US to get them
repaired. I would like to try to fix this myself but it would be great
if I can get more specific instructions for the following (from
http://wiki.laptop.org/go/Fix_Clock):

Using an OLPC serial adapter, connect the laptop to your personal
laptop. On the laptop's motherboard, the serial adapter should be
connected to J1. J1 is a small white connector near the wireless
module.

Since I am not familiar with computer hardware at all, here are my questions:

(1) Can you tell me specifically which OLPC serial adapter to buy if I
do NOT want to solder any wires? It would be ideal if you could send
me a link where I can purchase the exact serial adapter online.

(2) I understand that the OLPC serial adapter must be connected to the
J1 Serial Port on the XO's motherboard but I am not sure what kind
of cable is required and how to connect the serial adapter to this
port...Can you send me a photo which illustrates how to connect the
serial adapter to the J1 Serial Port? (It would also be good if you
can include a link to where I can buy the specific cable online.)

Thanks in advance for your help! We want to start training local Kyrgz
kids here but we're surprised when many of these new XO laptops could
not boot up.

Need Help: usb drive not visible in the journal

2009-08-01 Thread sumit singh 
Hi all,

I am facing a sort of weird problem at this point. On my xo, my usb
drives are not visible in the journal. I mean the icons at the bottom
of the journal are not visible. However, to my surprise my usb
drives(pendrives) are mounted and I can access them from the terminal.
I have tested it with 3 pen drives so I don't think its due to my pen
drive. Moreover, these pen drives are not even visible in the
objectChooser widget when I invoke it through any of the xo activities
like write or paint.

Can anybody please suggest me a solution. Moreover, is there any way
to access the data in the journal through the terminal, I mean there
are many activities which saves data into the journal and I am in
severe need to access that data. Is there any way to do so. I got this
link-

need help troubleshooting possible jffs2 problem

2008-09-02 Thread Bryan Berry 
I am having w/ one of the XO's from a pilot school.

I cannot copy large files from a USB key to the local SSD. The SSD mtd0
is only 47% full. I am trying to transfer a 156 MB file. The XO crashes
when I try to copy the file locally. 

The XO works fine otherwise. I have run test-all and seen no errors. I
have reflashed the OS image (703) and still encounter the problem. The
reflashing process did not display a larger than normal # of bad blocks,
probably only 6-7.

This leads me to think there might be an issue w/ the underlying jffs2
filesystem.

Can someone help me answer the following questions?

1. When I reflash the OS using copy-nand does it reset the filesystem?
2. How can I troubleshoot filesystem issues in general on the XO?

thanks

Need help: mounting usb devices on headless machines

2008-08-07 Thread Martin Langhoff 
Fedoristas in the crowd,

I am trying to find a tool that allows me to

 - automount usb devices when they are plugged in (via udev/hal)
 - would be nice to support removable devices
 - trigger an associated script on mount
 - all on a headless server!

There is no udev/hal automounter that works on headless servers
currently shipping on Fedora. Ivman is packaged, but not shipping
currently (dead upstream, very cumbersome config). Working with the
lvman config files is _not_ fun, and not modular at all - if several
school server pacakges want different things, it'll be a mess.

I have found an alternative that I like more, usbmount, which seems to
work, is trivial to configure, provides the subset of Ivman that I
need,  and makes it simple for other packages to drop hook scripts
into place via /etc/usbmount/mount.d . It doesn't have an active
maintainer though.

So I need some help :-) and it's not too complex.

Option one - point me to something that works and is maintained -- if
you know of a good reliable tool that I missed, I want to know. Can
you help me configure it for this task?

Option two - help me package  tweak usbmount for F7 and F9. The
codebase is *tiny*, we can carry it.

Option three - you are very keen on wrangling ivman's complexity and
baroque xml. Grand! Let's teach it to do /etc/ivman/conf.d/ :-)

Option four: anyone with a better plan?

I'll probably start chipping away at #2 tomorrow...

usbmount is a slightly longer and nicer version of that, which will

 - mount various partitions if various partitions are available
 - run scripts from a foo.d directory using run-parts
 - various options including logging

See for yourself here -
http://svn.debian.org/wsvn/usbmount/trunk/usbmount/usbmount?op=filerev=0sc=0

Having it as a middle-tier does a couple of things
 - insulates the other packages from HAL/udev changes. Is it
udev_volume_id or vol_id?
 - each FS get mounted once and but  N scripts from different packages
can be listening for that mount event

my plan is to add beeps too, with a special beeping pattern if
something goes wrong. Time for a learn morse-code activity on the
XO?

I don't think so - as I mentioned before, upstream is mostly dead, so
I doubt it'll be accepted. Trivial as it is, I am happy to support it
for as long as we have a use for it within XS. If something better
comes up, we'll switch in a blink.

Supporting it for Fedora is a wider (more varied uses) and longer timeframe.

Need help creating .xo file

2008-06-04 Thread shivaprasad javali 
Hi All ,
  I was wondering if you could help me out with this.

 I got the activity working fine on the OLPC. Now I want to create a
.xo file for my activity so that I can install the activity on other XO's.
My activity structure is as follows:
-activity --has the .info file and the icon
-bin  -- has a shell script and the exe which i have to run
-lib  -- has the libs which my application is dependent on
- MANIFEST file

There is a shell script in the bin folder which I have included in the exec
tag in activity.info.

I created the activity bundle according to the information in the post
http://olpcnews.com/forum/index.php?topic=1555.0 .
I have named my .xo file name.activity.xo

If I unzip the .xo in the Activities folder and then restart the X-server it
gets installed and I get the icon in the activity tray.

I tried installing it by copying the .xo to a thumb drive and then running
sugar-install-bundle on the XO but it gave me a DBUS timeout error. I also
tried to install it through the browse activity as given in
http://wiki.laptop.org/go/Activities#Manual_installation and through the
Journal without success.

Can you figure out where I am going wrong??

Thanks

The Bundle installs correctly only when I unzip it manually and then restart

Anyway when I tried to install through the sugar-install-bundle command It

Need help installing an activity

2008-06-02 Thread shivaprasad javali 
Hi,

 I prepared a .xo file for my application to be installed on the XO. I
created the .xo file by running the zip command on the activity folder. Now
if I have to install the activity through a thumb drive, I go to the
terminal move to Activities folder and then unzip the .xo file there. Then I
have to restart the xserver for my activity to show up on the home page.


Is there any way I can install the activity like this without having to
restart the xserver or restart the xserver implicitly??

Also can I do the installation through the journal if I have the .xo
file on a thumb drive??

Hi Bert,

  I tried sugar-install-bundle its giving me an error timeout in the
network connection. Do i have to be connected in the network before I can
run that command??

 Also i tried Simon's suggestion in the follow up mail. When i try
to install it through the browse activity it just stays on that page for a
long time with a waiting mouse cursor and then abruptly quits without
installing the activity. Also i cannot find an entry for that download in
the journal

 Can you think of anything that i might be doing wrong??  When I use
unzip to unzip the .xo file in the appropriate directory and restart the

Need help with making flash partitions

2008-05-13 Thread Artem Bityutskiy 
Hi,

I am trying to create an UBIFS image for OLPC and ask the community
to evaluate it. But I have some troubles I need help to deal with.

The basic approach I am going to use is to create 2 flash partitions
- boot and root. Boot would contain /boot and have JFFS2. OF would
boot the kernel from this partition. Boot would be small, just few
Megs. Root partition would be large and contain everything else and
would be UBIFS.

Mitch kindly referred me to this web page which tells how to create
2 partitions: http://wiki.laptop.org/go/OFW_NAND_FLASH_Updater

My aim is to make UBIFS installation easy - people would just copy
some files to their FAT-formatted USB sticks and reboot. Just like
you update your laptops with JFFS2 images.

But I have troubles with security. Namely, if I change data.img, OF
complains about invalid signature. I tried to remove data.sig file -
it does not help. I tried to put my developer key to the USB stick -
does not help as well. I use B4 prototype and security is disabled
AFAIU.

Any suggestion? Thanks.

As we approach 1.0 it will make more sense to have an XS beginners

I found 2 things reading this thread, let me explain what I did,
a) my activity directory was writable by world, why i did this was
becuase i was creating a config file and didnt know the user which
initiates my activity
b) the scripts which were executeable i.e. my Activity main script,
was only readable but still works ( can some one elaborate that for
me? i am a bit confused that how its readable but still executed )

1 thing more, when my activity is running, going to home view shows 2
icons, 1 is the activity icon that i created, 2nd is the black circle
in the right that is associated with my activity. can some body give
me a hint that where i am wrong ?

 I have not read the relevant Rainbow source, so I cannot comment very

 I used the phrase debug the system.  That was a poor choice.  I should

 Your experience is extremely unusual and non-representative.  You are an
 expert computer scientist who frequently reads source code written by
 others.  You are familiar with the OLPC operating system details,
 including D-Bus and the Bitfrost requirements, perhaps moreso than anyone
 else in the world.

 The people who will be reading these logfiles will be developers who are
 trying to debug their activities.  The activity may have crashed because
 it attempted to violate a Bitfrost rule and was killed by Rainbow.  These
 developers (ideally mostly children) will likely be building their
 activities by making small modifications to existing activities.  That
 means most won't even understand their own code.  How could you possibly
 expect them to understand yours?

 Not fixing.  It is absurd to imagine that any appreciable number of users
 will be able fix Rainbow bugs.  Rather, when Rainbow experiences an
 internal error, it should be extremely obvious that the problem is with
 Rainbow.  For example, an excellent type of behavior would be for Rainbow
 to print, in the logfile:

 RAINBOW BUG: Rainbow has encountered an internal error.  This indicates a
 bug in Rainbow.  The error code is 752.

 This line would be sufficient for activity developers to understand that

Ben is right. I think the problem is that your activity dir is world
writable, you could try changing that and continue testing your
activity inside Rainbow. Compare the permissions of your activity dir
and contents with other activities.

Can you enter a ticket about this? I don't know if Rainbow should

I would argue that activities should not be allowed to write to their
bundle directories, and that Rainbow is enforcing the correct
requirement.  I am calling this a bug because Rainbow should achieve
this without an assertion failure.  According to my software engineering
professors, a program should always handle any input data without an
assertion failure.  Assertions are for catching bugs in internal
invariants.  Therefore, any time an assertion failure is reached, it
represents a bug.

If Rainbow wants to disallow this, it should raise a specific exception.

Again, who is the audience for the message? It was clearly helpful for
Tomeu and me; it was clearly not as helpful for Waqas. Waqas - what
could Rainbow have done better for you?

1. I find Rainbow very impressive, and I am sure you are well aware of the
various arguments made regarding error handling.  In my view, restricting
assertions to internal invariants provides an easy way of distinguishing
problems in Rainbow from problems in Activities and other parts of the system.

2. Among your goals, you might consider maximizing the ability of novice
programmers to figure out what they've done wrong.  OLPC's goals include
bringing in many developers who have no experience, so it is important the
system be friendly to, say, Python programs written by people who don't
know Python.  The wiki page on translation even goes so far as to
recommend using gettext for error strings, so that users and
administrators may debug the system without knowing English.

3.  Did this assertion failure result in the termination of the Rainbow
daemon?  It certainly seems like it could have, though your response
suggests otherwise.  Most programs simply exit after an assertion failure,
because the failure indicates that the program's internal state is no
longer sensible.  Raising exceptions for input errors has the distinct
advantage of allowing one to catch exceptions thrown further down the call
stack, instead of exiting.  Note that when I say specific exceptions, it
would be perfectly reasonable to wrap up all errors due to permissions in
a PermissionsException, etc.

 1. I find Rainbow very impressive, and I am sure you are well aware of the
 various arguments made regarding error handling.  

Thank you. While it's true that I'm aware of some arguments regarding error
handling, I'm always interested in improving. It seems like one of the
most regularly failed challenges in the craft of programming.

 In my view, restricting assertions to internal invariants provides an
 easy way of distinguishing problems in Rainbow from problems in
 Activities and other parts of the system.

True, but the convention that I have established of separating error
messages into contract-violations and 'everything else', recorded in
per-activity logs and in a daemon-wide log (/var/log/rainbow) would seem
to accomplish similar goals.

 2. Among your goals, you might consider maximizing the ability of novice
 programmers to figure out what they've done wrong.  

It's not my primary goal, but I'll agree that it's worth considering.

 The wiki page on translation even goes so far as to
 recommend using gettext for error strings, so that users and
 administrators may debug the system without knowing English.

I'm still not convinced. Wouldn't we be better served by translating the
source code itself, or an overview of the source code like my 'Taste the
Rainbow' pages?

Consider: in my experience, debugging consists of searching the diff
between one's mental model and reality from which it follows that the
material which should be translated is the material which provides the
clearest, most accurate mental model of the problem.

Also consider: had there been an actual bug in Rainbow, which would have
been more useful to Waqas in diagnosing and fixing the problem:
translated error messages or better written or documented source code?

Put another way, doesn't this kind of error message uselessly duplicate
information that is best recorded in the failing assertion itself (and
in the name of the function containing it, in this case, 

  check_cwd(... [cwd=]/home/olpc/Activities/Qirat.activity)
  assert ck.negative(W_OK, 0)

?

 3.  Did this assertion failure result in the termination of the Rainbow
 daemon?  

The present implementation calls clone() before executing any
activity-launching code. Termination of the child by failure to handle
the AssertionError is a design goal.

 Raising exceptions for input errors has the distinct
 advantage of allowing one to catch exceptions thrown further down the call
 stack, instead of exiting.  Note that when I say specific exceptions, it
 would be perfectly reasonable to wrap up all errors due to permissions in
 a PermissionsException, etc.

First, what can I reasonably expect to accomplish by catching such an
exception? Second, given that the exception is being raised in a child
process that may have been compromised by malicious data, I'm not
terribly interested in informing the main daemon to the particulars of
the failure; the log file is quite sufficient for my purposes.

I have not read the relevant Rainbow source, so I cannot comment very
intelligently on this.  However, if Rainbow wishes to log a contract
violation, it should insert the phrase contract violation into the
logfile.  Otherwise, how is a person reading the log to know this?

I used the phrase debug the system.  That was a poor choice.  I should
say recognize bugs in the system, and additionally distinguish between
bugs in the system and bugs in the activities they're developing.

Your experience is extremely unusual and non-representative.  You are an
expert computer scientist who frequently reads source code written by
others.  You are familiar with the OLPC operating system details,
including D-Bus and the Bitfrost requirements, perhaps moreso than anyone
else in the world.

The people who will be reading these logfiles will be developers who are
trying to debug their activities.  The activity may have crashed because
it attempted to violate a Bitfrost rule and was killed by Rainbow.  These
developers (ideally mostly children) will likely be building their
activities by making small modifications to existing activities.  That
means most won't even understand their own code.  How could you possibly
expect them to understand yours?

| Also consider: had there been an actual bug in Rainbow, which would have
| been more useful to Waqas in diagnosing and fixing the problem:
| translated error messages or better written or documented source code?

Not fixing.  It is absurd to imagine that any appreciable number of users
will be able fix Rainbow bugs.  Rather, when Rainbow experiences an
internal error, it should be extremely obvious that the problem is with
Rainbow.  For example, an excellent type of behavior would be for Rainbow
to print, in the logfile:

RAINBOW BUG: Rainbow has encountered an internal error.  This indicates a
bug in Rainbow.  The error code is 752.

This line would be sufficient for activity developers to understand that
the problem is not simply in their code. It also makes it possible for
users to participate usefully in the development process, by reporting the
bug in an unambiguous way.  Error codes are also important because they
allow users to identify problems even when e-mailing logfiles is
impossible due to software bugs or lack of connectivity.  This error line
is also nice because it only needs to be translated once, with the error
code number substituted programmatically.

This output could be improved further by adding an additional sentence,
such as:

This error code indicates that Rainbow's directory permissions have
reached an inconsistent state.

This line, like a BSOD, serves mainly to make users feel like the system's
designers want them to know what's going on in case of a failure.
However, the implementation overhead is undeniably high, especially given
the need for many translations.  On the plus side, these strings also
serve as documentation when reading the source code.

You appear to have discovered a bug in Rainbow, which is dying with an
assertion failure.  Until Rainbow is fixed, you should do as Walter
suggested and disable Rainbow.

Re: Need help to resolve any problems

2007-11-19 Thread Reinier Heeres 
Hi Cihan,

Your icon tries to embed a gif file. The actual image data, however, is 
not in there. Try drawing a couple of lines in inkscape and it'll 
probably work.

As for your MANIFEST file: you need to list the files like this:
just.png
question.png
DefaultConfig

So remove the Ghost.activity/ from the beginning of the lines. Also I 
don't think you have to include the activity/ directory, as 
activity.info and the icon will be included automatically. Also leave 
out other directories, and list the individual files.

Cheers,
Reinier

Ghost My new Activity need help.

2007-11-16 Thread Cihan Akkurt 
Hello,

I developed a new activity for OLPC and I would like that someone can check
on a real machine. I need this test to find out if I have to install modules
/ packages before using the software.

In my code, I use import Image (PIL), and I do not know if it is already
installed by default OLPC

I also have a problem with the current directory. In my files. Py the path I
/ home / cihan / Activities / Ghost.activity /
example: locale_dir = / home / cihan / Activities / Ghost.activity
 and I would like to make it easier for portability. I have already tested
os.getcwd () function on Ubuntu but not in the emulator Sugar

I can sent the activity  by e-mail.It is 7 mb.

Sorry for my bad English. I can french if someone can French.

Thanks for your response.

You can see what software is installed in the build logs, e.g.

http://xs-dev.laptop.org/~cscott/olpc/streams/joyride/build286/ 
devel_jffs2/build.log

and you can verify it works by emulation:

http://wiki.laptop.org/go/Emulating_the_XO

The cwd is set to your activity's bundle directory, so you can use  
simply use relative paths to access resource files in the bundle.
