Testing Summary, Auckland 14 July 2012
Who: Brenda, Fabiana, John, Nevyn, Tom

We tested 12.1.0 build 18 on XO-1.5 and XO-1.75

Nolan (XO-1.75):
paint - seems ok.
Physics: get the strange behaviour at the top of the canvas where things 
don’t show over a band on the top (reported before)
Record: patchy movie recording on high quality from the onset, whereas 
my feeling is that previously it would record ok for a while before this 
happened.
Turtle art: Something odd - seems like I am building the blocks and the 
programme starts running without me asking for it.
Chart Activity: Opened a very big file from measure - it kept on going 
forever. I cannot find a way to tell it to stop reading the file. I 
tried to stop the activity but it looks like it will not stop until it 
finishes reading. After a bit the menus at the top of the screen were no 
longer visible (as if it was trying to stop) but I can see the data 
field and the chart field, which is still bringing in and 
displaying/plotting the data

Moa:
Managed to successfully open google doc, still can’t create a google doc.

Open as a new tab does not work on a google search

vmeta works in whaawmp, videos can be obtained with youtube-dl -f 18.

fototoon is awesome and works great

Yes we have been investigating this fir some weeks now, unfortunately seems to be a regression in the
hardware graphics driver that is not going to be fixed in this cycle. My best guess is that pygame double
buffering is no longer supported by the driver and your observing a vsync related frame redraw that should
be happening in the hidden buffer. The blank band will grow as the scene gets more complicated :( Other
pygame activities will also be affected (I've seen one mention of someone seeing something similar in Maze).

I've looked to see if there's anything I can do to improve Physics at the activity level, but haven't found
any options yet.

Thanks for testing.

The zero voltage point of the input channel won't always be zero in
the digital data.  This is specified in the datasheets for the chips.
Measure would need to learn the offset, with some sort of calibration
button.  This has always been the case, but the offset varies across
laptops.  You might find other laptops have other offsets; displaying
something other than -10.

You're referring to Daniel Drake's suggestions on 18th June.

Yes, but this wouldn't test what Daniel was asking, which is whether
the problem follows the microSD card.

Even so, I'll provide an answer to your question.

To do an fs-update with an external SD card, or microSD card in an
adapter, set the device alias used by fs-update, like so:

	ok devalias fsdisk ext:0
	ok fs-update u:\file.zd

As a result, the fs-update will write to the external SD card slot
instead of the internal storage.

To copy the operating system to an external SD card you may use Tiny
Core Linux booted from a USB drive.  The microcore build gets you a
root shell prompt without requiring the USB drive to stay in the laptop:

This could be http://dev.laptop.org/ticket/12003 if the banner above the OFW prompt states something like "DA" where the second letter is not a digit.

If this is the case the XO is fine. It just has a newer motherboard version than what the current software build expects.
