User:Skierpage

I'm a fan but just a casual G1G1 user and occasionally run images on Windows.

I edit wiki pages here on wiki.laptop.org (I document/support/test the wikipedia:Semantic MediaWiki extension so I'm fairly knowledgeable about MediaWiki).
I file bugs.

You can e-mail me as "info" at my web site, skierpage.com.

Leave me a note...

Here or on my "talk" page (click the [discussion] tab, click [+]). Remember, sign your edits with -- ~~~~.

(From joe)

Hi,

Thanks for the info. The format that Charlie, et al are creating would supersede the format shown on the "Testing" page. This is still a "work in progress".

Regards,

Joe

From Kiko on GStreamer

Hi, i see you´ve made plenty things with video streaming... I´d like to port autocast to the xo. <-- the first video you see was our first prototype test,, do you get the idea,, we were switching video from many cameras by recognizing audio from each speaker,, now i would really like to get video streams from the XO cut "on the fly" and streamed to the web (to be recorded by service similar to youtubes quickcapture or re streaming with G.I.S.S. tv...

Is there a way that we can skype for a sec, that you can give me advice on how to find a way???

it would be so great... : ) kiko att gmail dott com

Documentation notes

The OLPC colors (1 Laptop -> XO) are (according to the wiki logo):

orange #f78f1e
green #6bbe45
blue #0093d0
reddish pink #e20177

XO-1 screen is 1200 wide x 900 tall.

Two toolbars are 149 (150?) pixels high.

What is the XO-1 font?

 fc-match 'sans serif'

suggests ? Deja Vu Sans. Hmm, what font to use for callouts?

Annotate screenshot in Inkscape?

click connector, drag onto screenshot, use connector end arrow, use Extensions > Modify ending colorXXX

? how to assign styles that color arrow and text?

Laptop screenshot key is Alt+1

XO experiments

Detecting if the user has Help installed

Help (activity) is just a shell around webactivity that starts at a local URL. But you can browse to file:///home/olpc/Activities/Help.activity/help/XO_Introduction.html in Browse. Here is HTML code to test if Help has been installed and ifso add a URL to it. I have no idea if this is any good, Google spat it out. Instead, the Library generation code in OLPC could modify the start page.

This code is at http://www.skierpage.com/olpc/show_help.html , but it won't work until you save it locally and open the local URL.

<html>
<head>
<title>Try reading help file</title>
</head>
<body>
<h2>OLPC is awesome!</h2>
<script>
// This script only works when run from a local file:/// URL.
var oRequest = new XMLHttpRequest();
var helpStartURL  = "file:///home/olpc/Activities/Help.activity/help/XO_Introduction.html";

document.write("<p>DEBUG: Attempting to read " + helpStartURL + "</p>\n");

noHelp = true;

try {
  oRequest.open("GET",helpStartURL,false);
  oRequest.setRequestHeader("User-Agent",navigator.userAgent);
  oRequest.send(null)
  if (oRequest.status==200 || oRequest.status==0) {
    document.write('<h3>Need help?</h3><p><a href="' + helpStartURL + '>Go read the help text</a></p>');
    noHelp = false;
  } else {
    alert("DEBUG: Error executing XMLHttpRequest call!, status is " + oRequest.status);
  }
} catch (e) {

  alert("DEBUG: An exception occurred in the script. Error name: " + e.name 
    + ". Error message: " + e.message); 
}
if (noHelp) {
  document.write('No local help, but <a href="http://www.laptop.org/manual">Help is available online</a>.');
}
</script>
<p>and the rest of the page...</p>

PDFs in Browse

Trying to view PDFs in the browser without the horrible download-journal-start Read dance. evince isn't going to make a plugin [1], they recommend mozplugger. I tried yum install mozplugger, it installed sox and gsm WHY??!, still no luck and maybe it messed up PDF download, I now get a Mozilla "rainbow-daemon" dialog not a nice Sugar dialog.

Maybe I need to install evince as well, since /etc/mozpluggerrc wants to start this? XO has evince library, but yum install evince pulls in literally dozens of other libraries so I cancelled.

Wiki experiments and such

Sugar: interwiki prefix broken

There's a sugar: interwiki prefix to make linking to pages on sugarlabs.org easier. E.g. on the Setting up a sugar development environment page, [[sugar:Supported systems]] turns into sugar:Supported systems which has the wrong prefix.

This should be fixable in an interwiki table somewhere on ??pedal.laptop.org. Special:Version indicates that wiki.laptop.org runs mw:Extension:InterWiki , so this could be as simple as editing an InterWiki.txt file somewhere. I e-mailed wiki-gang and sysadmin "sugarlabs links breaking, need to update sugar: interwiki prefix" on 2008-11-13.

Activity versions for a particular release

Starting with 8.2.0, people have manually created then updated fragments and pages recording which version of an activity works with a release, such as Activities/G1G1/8.2. The Software updater Sugar Control Panel feature requires this.

But there is no such page for earlier releases. You can go look at the bottom of an activity's page (e.g. Chat) and it lists versions of the activity and what release they work on:

Activity version number:	40
The releases with which this version of the activity has been tested.	8.1.1 (708)

Unfortunately, the way User:Femslade designed Template:Activity_page/bundle , you can't run a query to "show the version and URL of all activities that were flagged as working on 8.1.0."

Here's a query that just lists activities with some version flagged as working on 8.1.1. If there's more than one, then go read its page! {{#ask: Software release::8.1.1 (708)

 |? Activity version=One of these versions works with 8.1.1 (708)
 |default=Nothing in Category:Activities with Property:Software release of "8.1.1 (708)"!?

}}

Here's a similar query that just lists activities with some version flagged as working on 8.1.0. If there's more than one, then go read its page! {{#ask: Software release::8.1.0 (703)

 |? Activity version=One of these versions works with 8.1.0 (703)
 |default=Nothing in Category:Activities with Property:Software release of "8.1.1 (708)"!?

}}

Activity list

Here's a way to extract info from an Activity group HTML file, assuming it's ruthlessly consistent:

 curl http://wiki.laptop.org/go/Activities/G1G1/8.2 > Activities_G1G1_8.2.html
 perl -ne 'chomp; next if m/Image:/; print if s:^.*?Download.*?href="(.*?)/([^/].*?)".*activity-version.*?(\d+).*$:[$1/$2 download $2]\t$3\n:; print if s:^.*/go/(.*?)".*:$1\t:' < Activities_G1G1_8.2.html > Activities_G1G1_8.2.lst3

clean up...

Gives /G1G1 8.2 HTML contents

for url in $(wget -q -O- http://wiki.laptop.org/go/Activities/G1G1/8.2%7Csed "s/>/>\n/g"|grep -v "^$"|grep "\.xo"|cut -d\" -f2); do
       prog_ver=$(basename $url|cut -d\. -f1)
       ver=$(echo $prog_ver|rev|cut -d- -f1|rev)
       prog=$(echo $prog_ver|rev|cut -d- -f2-|rev)
       echo $prog $ver $url;
done > Activities.lst3

XO Korea mystery

The gargantuan over-complex XO Korea structure from User:Php5 means searching in English finds Korean pages, such as:

How many pages in Category:XO Korea?

{{#ask:

 |format=count

}}

I sort of love php5's overcomplex microcosm, though :) and these days it's down to 10% of the whole... it reminds me of the bulk import of chinese characters and their meanings into an en-language dictionary, which overwhelmed /that/ random-page feature for a couple of years. --Sj talk

Damn transclusion woes

A bunch of pages were transcluding Friends in testing/current image number, like Template:Joyride-jffs2-link. Francesca (?) put a semantic annotation in there, which added it to hundreds of pages.

I hid that in a noinclude, but for some reason that messed up pages.

Let's try it here with a local copy in User:Skierpage/current image number, transcluded into this link:

joyride-2263

Testing my XO

Responding to the Friends in testing call and olpc-devel announcements... (My most recent tests come first).

release 11.2.0 (release notes)

I tried sudo olpc-update candicate-870 anyway, from 10.1.3.

(See message in response to "olpc-update works on XO-1!" thread for olpc-devel mailing list.)

update failures

sudo olpc-update -v candidate-872 never succeeded, and now sudo olpc-update -v candidate-872 fails as well:

Trying irsync_pristine update from rsync://updates.laptop.org/build-candidate-873

Before I start I ping updates.laptop.org and it works. Sometimes afterwards the ping fails. It finally succeeded, consensus from e-mail to Testing is it's network woes.

Tried again and it got lots of rsync timeouts and errors, but finally succeeded (?) with "Performing full rsync". I don't trust it.

Freeing up space

Update ran out of space. That's not surprising, olpc-update works on XO-1! says "it needs ~470MB of free space to work and os860 pristine [10.1.3] leaves only ~380MB free."

I erased Firefox and Help activities from the Home ring, but they left MB of data in ~/.sugar/default/org.laptop.FirefoxActivity and ~/.sugar/default/org.laptop.HelpActivity. (This is SL bug #2074, fixed in more recent Sugar.)

I had some content (aka Collections) in Library that didn't show up in the Journal (or Home view), like WorldDigitalLibrary and WikisliceChemistry. This seems mostly content shipped with the release, see Collections#Removing a collection. TODO BUG: Verify in 11.2.0 then file a bug that there's no UI to remove this.

Success, 11.2.0!

Third `sudo olpc-update -v -v candidate-os870` completed OK, I shutdown (BUG?? no more Restart menu item in Home view?).

Held down check key. Same q2e45 ROM as before. Long pause on (roughly) "purging old something, this may take a while". X11 cursor, then Sugar spiral!

Old BUG: OLPC "Hello, children of the world!" message doesn't fit, longest line has " wereld!" running over.

A whopping 437MB free, presumably because the whole /versions/contents holding a previous version is gone, also hadn't run Software update yet.

How come Activities has Helpxoyuy1CT and writexofwuzad? (I noticed a file named similar to the former in 10.1.3.)

Where is Library content? My Libraries has only some .xols I installed, none of http://download.laptop.org/xo-1/os/candidate/870/os870.libraries.txt

The spiral home view got the Software update prompt, I let it run.

While Software update was up, I could tab to the Journal but couldn't type anything in its search box or do anything.

That said You can install 31 updates. ??!? That seems crazy, why is a recent build so out of date? I guess all the activities and library stuff doesn't come with the build but is triggered by Software update.

What happened to Alt-Ctrl-Neighborhood (Console), I couldn't bring this up, maybe also because Software Update on screen.

In Terminal, can't click both buttons to paste primary selection. As others noticed, Shift-Ctrl-C doesn't work, but in fact nothing works!

SoaS 2009-06-03 image

I ran livecd-iso-to-disk.sh on Kubuntu to create an XO USB boot disk.

Screen font tiny during text boot Screen cleared in text boot, then displayed more text boot.

Got

then more debug output in the shell

Soas2 20090312

On a 2GB USB flash drive I let Live USB Creator create a 700MB area. But booting into Sugar Journal immediately popped up out of space.

I removed /usr/lib/perl5

I went to Collections, downloaded the story book, and Sugar crashed with some kind of exception taking me back to the "liveuser" blue login.

But the book was in my Journal and I could start it.

Browse

No home page, would be nice if there was one by default showing the media.

On login fields like wiki.laptop.org, font size in text and passwords way too small.

Curved edges on Textarea unpleasant.

rawhide-xo

Retried 20090312 , worked. Glitches in e-mail to fedora on XO and in new Rawhide-XO page

Tried http://dev.laptop.org/~cjb/rawhide-xo/ 20090307

Used `cat /proc/partitions` to figure out my USB in cygwin is /dev/sdb

$ zcat 20090307.bootable.gz > /dev/sdb

gave

gzip: stdout: Input/Output error

Probably because stupid SanDisk "2 GB" USB is actually "2,043,633,664 bytes (1.90 GB)". But since chkdsk reported no errors, tried it anyway.

Tried booting anyway, just stuck it in and restart.

type-vfat ro liveimg quiet ...

dmesg reported a ton of FAT: Filesystem panic invalid cluster chain errors.

In this error console, several commands I typed like dmesg | less led to unresponsive shell -- I would type commands and get nothing.

candidate-802

upgrade from candidate-801 (just a new firmware?) went fine.

candidate-801

upgrade from candidate-800 went fine.

On resume from standby, Sugar would often pick mesh instead of my WEP-password Linksys BEFW11 router AP. hard to tell if it's any better than 8.2.0.

candidate-800

From build 767, sudo olpc-update candidate-800 worked fine

Usual set of errors on the console

Still got

 some USB errors on the console during boot.

failure reading codec reg 0x7e error twice

xkbcomp error

Wireless access point using WEP working OK?

Shortly after boot the Frame showed mesh icon only. Went to Neighborhood view and as I was hovering over my preferred AP, it started connecting to it.

On next boot, by the time I looked at the frame, I was connected to my preferred AP.

Screen stayed on, shutdown hang.

With Home View and Browse running, I closed the lid. I noticed it was warm. The screen had been on all the time! Weird.

I chose Home View XO > Shutdown, console screen showed

  xinit: unexpected signal 15.

and I couldn't get it to actually power down by pressing keys. I held down the power button and it powered off.

clean-install of 650 back to the future

To see how olpc-update works from candidate-765, I ran Clean-install procedure to get os650.zip and fs.zip on a USB flash drive.

First Erasing, bunch of black squares, then Writing, bunch of green then yellow dots. A few red ones.

then a restart, then Ship.1 build 650 Christmas 2007 baby!

No sudo, had to su -l but then

 olpc-update candidate-765

more or less worked. irsync_pristine and irsync_dirty failed, but No out-of-memory.

During first boot,

error about no /home/olpc/.ssh
error about chmod u+rw something something not valid.

No ~olpc/Activities

Software updates "Checking for updates" "Loading groups... took forever, part of progress bar blanked out. <trac>8681</trac> ?

I looked in journal, and there were two entries, "pi Seconds ago" and "oi 24 minutes ago", with a _-_- document logo. (I had just changed my timezone, maybe the time was off.)

Problems updating to 765

Mail "Signed candidate-765 and gg-765-2 builds available for testing" went out. I renamed my developer.sig key and tried

 sudo olpc-update 8.2-765

but that build isn't signed so update complained so I killed it.

So I tried

 sudo olpc-update candidate-765

that completed, suspiciously quickly.

But now my XO won't boot

 Q2E1`8  Q2E
 Trying nand:\boot\runos.zip
   OS found - No signature for our key
 Boot failed  :-(

If I press the [o] key to boot the alternate image (which is presumably my previous unsigned build), I get the same error.

Solved by putting developer key on USB flash drive

I solved this problem by copying my backup of develop.sig to /security/develop.sig on a USB flash drive. With the USB flash drive inserted, booting from unsigned nand code worked.

Then I re-ran

 sudo olpc-update candidate-765

and it worked fine.

Damn U3 technology f***s up USB drives

If you buy a USB flash drive, it probably has crappy invasive U3 technology. Even if you have autorun turned off, Windows' "helpful" USB driver auto-install will automatically install some stupid driver that presents the flash drive as both a removable drive and a CD-ROM. WTF!??!

So download and run http://www.sandisk.com/Assets/u3/launchpadremoval.exe , then open Device Manager and make sure you don't have a second CD-ROM.

Paint-23 on 8.2-763

(I sent this to devel list.

Paint-23 on 8.2-763. These are roughly in menu order.

If from Journal I double-click on a Paint activity icon, I get two icons in the Frame, one of which has a doubled menu ("Paint Activity - Resume - Stop - Resume - Stop") that I can't resume or stop. When I tried to reproduce I got two icons, the first had the doubled menu, but this time the second icon pulsed forever.

You can't name a paint session in Paint (6220, I added this to release notes).

I can copy Paint's marquee selection and it appears in the frame, but the selection seems inactive -- it's gray, has no hover menu, I can't drag it.

I couldn't get paste of a selection to work.

The Paint fill is so slow that I assumed the app had died.

The Tools menu looks like a tools palette but you it doesn't show the selected tool. Actually, there is one item that looks like a selected tool, but it's the rounded-rect around the current color.

The color selection swatches would be a lot more obvious if they started out as the kid's XO colors instead of black and black.

Meanwhile the T in the text menu does have a gray background as if it's selected, but it isn't until you click it. And the two effects icons have a white background as if they're active.

If you type a pencil or brush size in their drop-down menus you can't dismiss the menu from the keyboard.

The Pencil size seems unchanged after changing its size.

Polygon tool cursor doesn't look like the polygon tool icon.

The Shapes menu doesn't fit the available space, "Triangle" is in a more items drop-down. I would get rid of the "Line" shape so the Shapes menu can fit on the regular screen.

The menu is "Text", its menu item is "Type". What's the difference?

The image resize spinboxes are so slow if I paste a previous Paint image in, I assumed the app had died. If I type in the image resize text boxes nothing happens but I don't know if it's really slow or they're dead to text input. Ideally they'd immediately show the value you type in or spin to but then you'd get a busy cursor.

I can choose anything from the Journal for Image insert, e.g. a terminal session, but nothing happens if it isn't a previous Paint session. Is Paint meant to insert the preview image of non-Paint sessions?

After unsuccessfully changing the size of an inserted image, the pencil tool works but the paint tool gets stuck as a selection marquee tool (makes no sense, but it's happened three times to me).

The two Effects operations are next to each other and have similar icons but do completely different things. It would be better to separate them, and change the hover text for the first to "Make picture gray"

Notes on Software update of activities

Running 8.2-759, Software update offers me

Distance 12 to 13,
Firefox 4 to 6
Measure 17 to 19
Paint 20 to 22
Pippy 25 to 26

Modify activity groups is empty. Is it still going to Activities/Joyride ? That page has CC Licensing Activity and Scratch, yet Software update doesn't offer them.

I ran update and screen went blank and machine restarted. After restart, got new list of offered activities.

Looking at an activity like Cobble, it has two repeating forms each with:

URL for the .xo bundle:
Version number:
Releases tested on: 7.1.0 (650) 7.1.1 (653) 7.1.2 (656) 8.1.0 (703) 8.1.1 (708) Candidate
Development status:

That's bad, because this info is tied to the page, it isn't associated with each other. Same issue as multiple test results.

Can we have many-valued property Works_on: "version (build)", thus "26 (Candidate)", "24 (8.1.0)" But need URL in there as well... So I guess we need subpages with version support for each stream.

Notes on Update from 8.2-759 to 8.2-760

 sudo olpc-update 8.2-760

in Terminal Activity worked great! irsync pristine worked, verification worked.

After restart I got messages about writing NAND. It seemed that the reboot didn't tell me it was installing new firmware version Q2E17.

2nd restart displayed Q2E17, then booted into Sugar.

Got prompt to run Software update, but that reported "Could not access the network". I often get this problem.

bug?: With Software update panel up, I can't get to frame with mouse, but pressing the upper-right Frame key will show the frame, though it seems inactive.

The Frame showed an AP so I retried and it worked fine.

Display pulses after standby (Out-of-memory?)

Twice with 8.2-759 my XO had trouble displaying screen after being in "standby", the screen flashed on every 30 seconds. See User:Skierpage/out-of-memory for notes.

I sent e-mail XO screen pulses after "standby", OOM afterwards to devel@laptop.org and filed <trac>8490</trac>

People think its CPU pressure not OOM. Alas, there's no guide of helpful stuff to type in low memory.

Notes on Update from 8.2-757 to 8.2-759

sudo olpc-update 8.2-759 gave me the same Contents manifest failure at line 383 Last file examined: localtime error (<trac>8190</trac>. and the same (?) out of memory error <trac>5954</trac>).

Supposedly these are fixed in build 8.2-758, so I shouldn't experience them any more.

Home View > XO Man > Restart left me at

I think this is known. By clicking power off and back on (i.e. not forcing a power off) it advanced to

Got a few hangs and instabilities.

Notes on Update from joyride-2230 to joyride-22713

Tried this, a later release than 2263 recommended by Friends in testing.

???? Next lines are the welcome kinds of the world for OLPC!

Other times I tried this and other joyride updates the Terminal Activity vanished and I was back in Home view.

So I did it in a Console, and joyride-2273 installed fine. Some errorsl

Note the crash in irsync dirty update, that was killing, not just sudo olpc-update, but the Terminal activity.

This sounds like <trac>5954</trac> oom-killer during olpc-update.

Terminal Activity mouse jumped to Activity, but then just the text "Activity" got stuck in the top right corner. if I brought up frame, it was still there, I couldn't choose a menu item of one of my running activities. Clicking other items in the frame, like network or speaker, would just highlight Activity.

I did Ctrl+Alt+Erase to restart X and Sugar.

Read of a PDF works, but Sugar activity handbook shouldn't be a PDF <trac>7898</trac> and I ran into "Keep error on exit" <trac>7843</trac>, I pasted my Read log error for the latter.

Read of a 4-page DjVu file shows 1/4, lets me advance, but doesn't show anything. When I page backwards it gets slow, then really slow, then cursor won't track and the machine is completely unresponsive. Had to power cycle. Nothing obvious in the error logs.

But then I tried again on another DjVu file from http://djvu.org/docs/, http://djvu.org/docs/1998_zcoder.djvu. All blank, showed 1 of 10. Then I zoomed out and saw the text of page 1!! But when I zoomed in, Read died, and Browse too!. Nothing in error log. I updated <trac>6223</trac>.

I couldn't find any help on the wiki in Support FAQ, searching for "freeze", etc. for what to do when the machine goes unresponsive.

Notes on Update from build 708 (8.1.2 candidate) to joyride-2230

Got a developer key, found a few bugs.

In 8.1.1, build 708, more /etc/issue shows

 OLPC build update.1 708 (stream udpate.1; variant devel_jffs2)
 Kernel \r on an \m

Bug: last line seems bogus!?

Couldn't

 sudo olpc-update 709

got "unknown moudle 'build-709': could not find build 709: are you sure it exists? Sure enough, rsync rsync://updates.laptop.org | sort doesn't list it.

OK, so much for trying 8.1.2!

Per Friends in Testing,

 sudo olpc-update joyride-2230

seems to work.

Are the first two failures expected? Seems like rsync will fail if it goes into standby? ffm|sh on chat says this is all expected.

Reboot

Note this update involves new firmware.

I pressed the check key to see information, below I type some of what I saw. I can't keep up with the text.

Trying nand:\security\developer.sig

Updating firmware...

screen went dark, happy chime

OpenFirmware CL1 Q2D16 Q20

trying key

OpenFirmware CL1 Q2D16 Q2D

Updateing firmware....

screen went dark, happy chime

Now OpenFirmware Q2E12 A2E

Is it expected that it restarts three times, second restart still running the original firmware.

Bugs, TODO

erased Log activity. No feedback after clicking [Erase] in confirm dialog. Still showed in Home view. If I clicked to start, I got endless pulsing icon.

Browse activity did go away when I erased it, as expected. (?)

Started Log after I'd erased it, it pulsed for a long time, then I had two Log activities on the Home view, one orange. ?!
shell.log had errors 'No such file or directory' from execute_child from HomeBox.py

~~cat /etc/issue has a garbled second line: Kernel \r on an \m~~
Not a bug, /etc/issue is a template that gets filled in on new terminal.

<trac>7828</trac>In Home view , hovering on an activity brings up {name of activity} with an Erase menu item. But in the journal, the default for each "session document" is "Write Activity", "Terminal Activity", etc. and those also have an Erase menu item. One of those removes the activity's code, one just removes a "session document". I get them confused.

<trac>7830</trac> The submit button in the DevKey form file:///home/.devkey.html looks weird, "stripey"

<trac>7831</trac> The Journal menu for Stopwatch activity installed from OLPC library is too wide to fit screen.

<trac>9260</trac> pippy examples can adapt to screen dimensions (the first Python code I've ever written!)
