Congratulations Tim :)

Hi Steffen,

The actual code for the extension has to be implemented in CodeHolder, correct?
How do I deal then with methods that need to access instance variables not
present in CodeHolder? Just add them to the class or is there another way?
Kind regards,

And how should I structure this on the Pharo site and in an iceberg repository?
One Git repository per package or all in the same? Is there a guide to this or
a specific Mooc lesson?
Kind regards,

Yes, PDFtalk is the only example, because it was created to port that library.
Any other uses are welcome.
The project has been dormant for a year now because of other obligations, but I
hope to resume soon.
The documentation is, as Richard notes, in a suboptimal state. I think that the
Yes, this is my camp .
Every layer or tool adds many cool features (their raison d'être) which you
don’t need for the "easy" setup.
You typically need only a handful of the configuration parameters at most
(imagine PostgreSQL, Apache, Jenkins etc.).
Yet, all the myriad of super-duper feature
I don’t see how rounding errors could accumulate, if you keep the sum and not
the average.
The rounding errors should be neutral, because each element is added once and
subtracted once.
If + and – is symmetrical in this respect, rounding inaccuracies should balance
out.

Hi Cédrick,
for smallCharts, I had to implement the same, but for stock market time series,
which are a bit bigger than your example (like creating a 38 day moving average
over 5 years).
Always copying the values to average is far too slow in this case.
My solution is to add up the

Please keep me posted when you are doing something.
Good luck,

In the end, you need to have bitmaps for the screen.
Rendering is the projection of vectors onto pixels.
But you don't want to lose the vectors, because you need them for interactions
(mouse, keyboard focus).
I think that it is extremely sexy to have an interactive viewer for PDF!

Yes, reading PDFs is fine with PDFtalk, but what you want is more: Text
extraction (there is a chapter in the spec about this).
This feature is not yet readily available. Some ground work has been done
(content analysis), but for full text extraction more work is needed.
Cheers,

Hi,
is there some basic intro to programming (for a 10 year old without prior
experience) ideally with Pharo 6?
Is Prof Stef suitable?

Hi all,
in two weeks, I am going to give a little talk about Smalltalk:
http://metameute.de/nook2016/ .
It is 45 min with students who probably never heard of Smalltalk.
I want to concentrate on the liveliness of the environment with the tools:
Workspace, Inspector, Browser and Debugger.
