Yes, I think that a beginners video channel would be a great idea! When I get to the stage of understanding things enough, maybe I'll be able to help. I have English as my mother tongue, and my sister is French, and speaks excellent English. I'm not promising anything, but it does feel important to me at the moment ;-) -- Cheers, Peter.

Hi Peter,

Interactive geometry software are very specilised software, so you need to understand how it works. Tutorial are indeed important.

My main problem is speaking language.

I have written documentation in French at http://www.drgeo.eu/screenshot-video I can't produce an english documentation with a good quality level.

We have some video tutorial at http://www.drgeo.eu/screenshot-video

Some of the video are in French other in English

But I should set up a Video channel for begginer to get started, it will be a great idea. What do you think?

Next about tutorial button within DrGeo, yes it will be a nice addition. It is someting I need to thing about.

Thanks for your feedback

Hej Hilaire!

I've bought the paid version, and it does look pretty nice. As you ask for feedback, I thought it would be OK to post it here, apologies to all if it's not appropriate!

Never having seen the app before, I was unable to find a help or tutorial button within my personal "frustration time". May I suggest that first-time users be started up in some kind of "newbie mode"?

I wanted to show this to my kids to demonstrate what amazing things are possible with Smalltalk, but for that to work I'd need to at least seem to understand it myself ;-)

-- Cheers, Peter.

Dr. Geo (aka Dr. Geometry) 12.10 for iPad is available on AppStore. It comes in two versions: gratis and paid. http://itunes.apple.com/us/app/dr.-geometry/id559858173?l=fr&ls=1&mt=8

Compare to the desktop versions, it is almost feature complete: only the script and programmed figure can not be created or edited with this version. However, sketches including scripts are interpreted and rendered correctly on the tablet.

*Feedbacks* and *rating* are welcome and greatly appreciated!

Thanks!

Peter, It will be terribly useful if you describe me where you get your frustration time. Thanks Hilaire Le 16/09/2012 11:53, Peter Hugosson-Miller a écrit :

Peter, I really need to know what were your expectations during this frustration time, so I will have a very clear indication about what and how I should improve. You can email me privately at hilaire AT drgeo.eu Thanks Hilaire Le 16/09/2012 21:23, Peter Hugosson-Miller a écrit :

Hehe, AFAIK, "frustration time" isn't a proper phrase, it's just something I made up to try and describe the time it takes from starting up a new program I've never seen before, until it makes me frustrated. In the best of cases that never happens, and I must say that it's highly personal, and depends largely on my expectations at the time.

In this case, I had already decided to buy the app, not knowing if I would have a use for it, just because I like to do things to help the Smalltalk community in any way that I can. In the back of my mind I also hoped it might be something I could use with my kids, to show them a bit about geometry, maths in general, and maybe even Smalltalk. I was not expecting a beautiful, polished finish, nor much in the way of documentation, but I'd hoped that, given a few minutes of time, there would be enough clues to be found by clicking and prodding around, to be able to make it do something cool.

Sadly, during the time I had available during that first look, I didn't manage to make anything happen at all, and I felt frustrated. I fear that someone with higher expectations might have become cross at that point, and that's why I wanted to suggest a tutorial button. Now I know that I just need to go and watch those demo videos before I try next time :-)

Hi Hilaire, I bought a copy for iOS as well. What are the differences between the free and paying versions ? And yes, you need a Help button with things like an overlay showing the main functions, a short tutorial (anything is better than none), a couple of demo projects and links to your website for support.

You can save sketch and draw circle and parallel line I am thinkng about video tutorial like https://www.dropbox.com/s/tr8wjxf6n9bq1n9/drgeoBigHand.ogv Hilaire

Ho Lorenzo, Philip wrote about simplex algorithm for DrGeo, but he did not gave examples of use case. Right now I can not tell if I will use it for Dr. Geo. But it is nice you asked. Something I will use for sure in Dr. Geo is a Computer Algebra System (even a simple one) written in Smalltalk. Btw, does any of you know Boris Gaertner, he worked in a CAS system in Smalltalk ? http://www.bgaertner.gmxhome.de/liouville.htm Thanks Hilaire Le 16/09/2012 17:04, Lorenzo Schiavina a écrit :

Hi Hilaire,

I am going to download a simplex algorithm for linear programming from a VSE version I developed some years ago; are you (or some other people) interested to it, as I have found that the porting is more complex than I have imagined.

Grazie

Lorenzo

Dmitry Golubovsky (Android) and Esteban Lorenzano (iPad) proved to be very reliable people to work with, they also have a good sense of human relationship. Thanks you guys.

Now I hope, to see more Android and iPad Smalltalk Pharo applications. It will really consolidate our ecosystem.

I really hope! We need more success stories like that one.

Thanks

Hilaire
