Re: [Pharo-users] Pillar Re: Neural Network - Handwritten Digit Recognition

you can change the size of the image using |width=60| it is expression is given in % I fixed it. I will read it and give you feedback. Now I just skimmed throw it and I would - structure the text with some sections like setup, importing, computing, rendering, conclusions - then I would turn the large roassal script in a tiny and beautiful class Stef On Sat, Feb 10, 2018 at 2:35 AM, Pierce Ng <pierce(a)samadhiweb.com> wrote: > On Thu, Feb 08, 2018 at 07:42:09PM +0800, Pierce Ng wrote: >> On Wed, Feb 07, 2018 at 08:24:29PM +0100, Stephane Ducasse wrote: >> > Here is the link https://github.com/SquareBracketAssociates/Booklet-IA-Neurons >> > I can give you commit rights. >> >> My Github username is PierceNg.

Thank you. Stef, thanks for adding me to the repo. I've plugged my blog post in as chapter 1. On Pillar, I see that the generated PDF shows the array inspector screenshot as an outsized image. What's the best practice on sizing images? Anyhow, I've set up Docker with the texlive:pillar image and just did a successful test run. I can now experiment with agility. :-) Pierce

Re: [Pharo-users] Roassal to ODG

by Peter UhnÃ¡k

There is SVG exporter. I've never heard about ODG, is it commonly used outside of OpenOffice itself?

Hi Arturo I have no idea about the answer.

cancel changes in Nautilus broken on 6.1?

by Siemen Baader

Hi all, I downloaded Pharo 6.1 for OSX and whenever I revert changes in Nautilus with CMD-L, the content is reverted and the orange dirty marker triangle disappears. But when I switch to a different method, Nautilus shows the 'Content has been modified. What do you want to do?' dialog, as it only should when content is actually different. I use this all the time, I can't imagine I'm the only one, but I couldn't find the problem mentioned anywhere. Does anyone else have it? What to do? -- Siemen

Roassal to ODG

by Arturo Zambrano

Hi all, Is there any project for exporting Roassal to ODG (vector graphic format from open document format standard)? The closest thing I could find is RTPDFExporter (the generated PDF can be opened using (Libre/S/G)Office suite). If there no such exporter, how difficult should it be to build one, compared to RTPDFExporter? TIA Arturo

Does it still work for Pharo 7 ? It should still be part of Roassal, with some issues with the data sources used to retrieve cities coordinates (they went offline!).
