I have two sets of data X & Y, which for all combinations of (x@y) I
calculate a third value z, which ends up represented as a collection of
"points associated with a value eg (x@y)->z)."
I'd like to chart this as a heat map - very much like a Scatterplot but
each point '(x@y)' has its pixel color dependent on 'z'.
Any ideas how to go about this with EyeSee ?

Ok, you are next. Raw version, not merged with screencast yet.
I assume having video fast, and fancy later is the way to do this.

Hmm,
Just finished uploading one hour of Pharo Roadmap.
Should be visible on youtube soon.
Next: Diego's Data Migration with Moose (still rendering,
could arrive somewhere late this night).
I'll let my machine render and upload a few parts
more. Fixing & cleaning is for later. They should take half
a day each or so.
I know a lot of Pharo people, but not all.
Can anyone tell me, who presented what (and when)
in the Show us your project?
Cheers,
Stephan
Hi,
I'm very happy to see that the initiative to make video recordings
of the PharoConf and MooseDay has resulted in so many
screencasts already published. Great work!
And now the first feedback:
- Format conversion: 62 of 72 GB done, processing the whole weekend.
- First 13 minute part currently encoding and uploading.
Still about an hour and a half to go.
- I would like to receive the presentation files to combine them
with video.
- Some of the material is difficult to use. Zoomed out too much
it is difficult to follow the speaker and the beamer screen is not
readable. Combining a screencast with the video only makes
sense when zoomed in (talking head size).
Why does this take so long?
- the video is in a format that I cannot work with directly, so needs transcoding.
I have been using VideoMonkey for this, which is based on ffmpeg. I have
the impression that this ffmpeg is not using the GPU, but only the i5.
I'm open for suggestions on better software for this in the future, as it takes the
whole weekend.
- I switched from iMovie to Final Cut Pro X. That allows non-linear editing,
so I don't have to wait for rendering to cut the movies. It remains responsive
even during the format conversion.
- video is much larger than the equivalent length of screencast. That creates
a upload bottleneck. 13 minutes of HD video is 733 MB. My home upload is
1Mbps (2 hours), so for uploading more material I'll ask someone at our
local university.
- I'm spending a limited amount of time during the weekend (and none next week).

Hi!
I am just back from teaching smalltalk and Moose. Many of the students are experiencing sudden crashes using Moose 4.7.
Apparently using regular expression on Moose 4.7 may lead to this crash.
Any comment?

Dear Pharo and Ubuntu users,
Nicolas Petton and I are proud to announce Ubuntu packages for the
Pharo VM. Installing the pharo vm is now just a matter of:
sudo add-apt-repository ppa:cassou/pharo
sudo apt-get update
sudo apt-get install pharo-vm
With this package, you get:
- the latest pharo vm as a 'pharo' binary in the PATH
- all plugins and libraries (native boost, freetype, ssl, ...)
- file association so you can just double-click on pharo images
- pharo icons visible everywhere (on image files, on ALT+TAB...)
- PharoV10.sources and PharoV20.sources
Please fill bug reports on https://pharo.fogbugz.com.
This package is currently only available for Ubuntu 12.10 Quantal.
Fill a bug report if you want me to package it for another version of
Ubuntu.

Hi Norbert,
You should indeed look at Roassal.
Could you give us an example of the data you have? Perhaps we can get you started with an example.
Cheers,
Doru

I'm implementing an communication stack [1] where the central behavior is a huge state machine / flow chart description [2] (the state machine / flow chart is described on page 30 to 60). This is a task that is hard to do right without any guidance. My idea is to figure out a way to annotate the sources in a way to get the right points in control flow from code. From this I like to create a diagram that is semantically equivalent to the description in the spec. I'll need therefor things to create state machine / flow charts, meaning shapes, directed arrows, branches etc.. Well, my dream would be to inject a real data packet into the communication layer and get a diagram where the path taken is highlighted :)
