GNU Dr. Geo release 18.06


We are pleased to announce the Dr. Geo release 18.06. It follows the release 17.07 in July 2017. 
A large part of the effort was to port Dr. Geo from the Pharo 3 to Pharo 7 Smalltalk development environment.  In addition to usual bug fixes, several features were added.
Mini changelog:
  • Dedicated Script browser
  • Inspector on Smalltalk Sketch 
  • Positioning zoom 
  • Unit tests based on Smalltalk sketch 
  • Lan share 
  • Graphic user interface theme 
  •  Fullscreen option 
  •  Lots of bug fixes 
Read the complete announcement

Dr. Geo is always looking for volunteers to translate its user interface.

QRCode - A thank you note

Last month I implemented a rough MVP-style ticket sales platform that was successfully used to sell and validate at the entrance, about 1000 digital, online tickets for a relatively large 3000+ attendance event (a party). It took only a couple of days to build and deploy, and it was a lot of fun - it was even done in 'unstable' Pharo 7.
Early on I decided to identify each individual ticket by a unique URL. For easier presentation and scanning purposes, I encoded that URL in a QR code.

Although I am grateful for the whole Pharo ecosystem (including Seaside), we all build on top of other people's work, I was especially happy with Jochen Rick's QRCode package. This is such a great piece of work!

It worked right out of the box in Pharo 7 (even though it is from 2013/2014), was well designed, easy to figure out, was well documented, had unit tests. I can't say anything bad about it, it is as close to perfect as I have ever seen. So: thanks Jochen, you made my day!

Here is how a ticket generates its own QR code:

T123Ticket>>#asQRCode
 ^ self url asString asQRCode formWithQuietZone magnifyBy: 5


Just beautiful.

It is also easy (for a non-graphics, non-UI person like me) to combine the QR code with some text and then compose that with a nice template designed by a graphics artist. Finally, the ticket form can be encoded as a JPEG (to be mailed and so on).
I also found GT Inspector very handy (again) in doing back-end work (managing payments and other administration), especially the ability to use Spotter on a collection open in an inspector.
Anyway, I know many of you have similar happy experiences, I just wanted to share (one of) mine.

Thanks Jochen, thanks, everyone.
