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...

(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 Tomhannen on emulation

Hi - this should help.

Experiments and such

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

• XO_Korea/hobby_and_profession/business_area
• XO_Korea/business_content/45120000_Photographic_or_filming_or_video_equipment

How many pages in Category:XO Korea?

{{#ask:

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

Notes on Update from joyride-2301 to 8.2-757

I got the same Contents manifest failure at line 383 Last file examined: localtime error, so filed <trac>8190</trac>. I got the same (?) out of memory error <trac>5954</trac>

Notes on Update from joyride-2230 to joyride-22713

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

Trac 5954 crashes

In Terminal Activity

sudo olpc-update joyride-2271

???? 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.

Various

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.

Some Linux boot warnings and errors

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.
