Re: [Pharo-users] Pharo things analog reads ?

by Steven Costiou

I finally bought 2 of those chips, and it works very well. A simple file read from Pharo and i get my analog values (although i don't understand them, but that has nothing to do with the reading). It is very, very fast. Thanks again :) Steven.

If what you are doing is an experiment or you want to play around with it, I would also recommend trying Bloc. https://github.com/pharo-graphics/Bloc On Sat, Dec 23, 2017 at 10:36 AM, Stephane Ducasse <stepharo.self(a)gmail.com> wrote: > Hello Doug > > You pushed me to try and I rescued an implementation for the old Squeak. > I published it at: > > MCHttpRepository > location: 'http://smalltalkhub.com/mc/StephaneDucasse/MandelBrotMorph/main > ' > user: '' > password: '' > > MandelMorph2 example > > If you want to improve it and implement others let me know I can give > write access to the repo. > > Let me know if you have fun. > > MandelMorph2 new openInWindow > > Stef > > > On Fri, Dec 22, 2017 at 9:39 PM, T.D.

Hello Doug You pushed me to try and I rescued an implementation for the old Squeak. I published it at: MCHttpRepository location: 'http://smalltalkhub.com/mc/StephaneDucasse/MandelBrotMorph/main' user: '' password: '' MandelMorph2 example If you want to improve it and implement others let me know I can give write access to the repo.

Re: [Pharo-users] How to connect to DB2

I have no problem using Garage to connect to Postgres. Don't know if it will work with DB2, but since it's ODBC, it should.

See the result here: https://github.com/OpenSmalltalk/opensmalltalk-vm/pull/176 I hope this will help with the publication of a new stable VM. It is also important for us at Synectique. To be able to have a 64bits linux applications reliable would help us a lot in the simplifications of our processes. :) I guess that it will still have to wait some time since it's the end of the year and there must be a lot of people taking holidays. > thx for an update > Johan -- Cyril Ferlicot https://ferlicot.fr http://www.synectique.eu 2 rue Jacques PrÃ©vert 01, 59650 Villeneuve d'ascq France

Hi Stef I already checked Garage, it doesn't have support for DB2. It used to have support for odbc, but now it's deprecated.

pharo 6.1 64bit segmentation fault on linux

by Johan Brichau

Hi, Iâm also hitting this issue: https://pharo.fogbugz.com/f/cases/20737/Segmentation-fault-trying-to-load-c… <https://pharo.fogbugz.com/f/cases/20737/Segmentation-fault-trying-to-load-c…> Also reported here: http://forum.world.st/Pharo-6-1-64-bits-segmentation-fault-loading-code-on-… <http://forum.world.st/Pharo-6-1-64-bits-segmentation-fault-loading-code-on-…> This stops us from using Travis-CI because the OSX builds are just way too slow there. Since more recent vms are working (see thread), any chance the vm for linux is updated on the pharo site so we can use Smalltalk-CI? thx for an update Johan

Re: [Pharo-users] Learning Morphic

by Hilaire

In the Pharo by Example book there is one chapter about Morphic. It is a good starter. Regarding the use of Athens canvas there is no such doc. You can take a look at the internal of Roassal or DrGeo or any package using Athens for graphics rendering. Morphic will be replaced by blocs -- Dr. Geo http://drgeo.eu

Learning Morphic

by T.D. Telford

I am primarily interested in graphical shapes and bit maps (for fractals). I want to put graphical shapes or bitmaps in a window or bordered area. I have not been very successful in finding documentation about how to do this in Morphic. In contrast, I find the documentation for Roassal easy to find and to the point. Perhaps someone could point me to Morphic documentation (or supply examples) on my area of interest that includes a lot of examples. Thanks.
