Dear HernÃ¡n, cool, really nice work. will have a closer look :-) It really is too bad, that it is so hard to find such cool packages. i im really missing a kind currated list of all the cool pharo packages around. somthing like awesome python, f.e. "https://github.com/vinta/awesome-python" BW, Volkert PS: Btw, loading the OSM support package failed (following the instruction on Page 45 of your docu).

Re: [Pharo-users] Geocoder Services in Pharo?

by HernÃ¡n Morales Durand

Hi Volkert Territorial (https://github.com/hernanmd/Territorial) is a library for geographical information retrieval. GADM is included in Territorial but is mainly for boundaries. The feature you ask for is not there yet, but if you want to try out other features or look for integration you can install it by doing: Metacello new smalltalkhubUser: âhernanâ project: âTerritorialâ; configuration: âTerritorialâ; version: #âdevelopmentâ; load.

VoyageMongo questions

by john pfersich

Has anyone tried to use VoyageMongo to connect to a MongoDB instance not on the local machine? I used the VoyageMongo from Smalltalkhub like the "Persisting Objects with Voyage" said and it looks like I had the same problem that Sabine mentioned on Discord; "Not enough space for external objects, set a larger size at startup", but there was a (another) problem and the image was toasted. I then tried to load VoyageMongo into Pharo 5 from the Catalog Browser and there's an error and it won't load. Any hints on what I'm doing wrong? I'm using Pharo5.0 Latest update: #50761.

Re: [Pharo-users] Implement Matrix whith OrderedCollection

by Sven Van Caekenberghe

Because all 16 elements of the first/top ordered collection contain the exact same element. They are all #==, the same instance/object. If you change one, you change them all. Here is one way to create what I think you want: OrderedCollection new: 16 streamContents: [ :out | 16 timesRepeat: [ out nextPut: (OrderedCollection new: 16 withAll: 0) ] ] BTW, Arrays would be better in this case, I think. > On 30 Apr 2017, at 23:08, frankl1_miky <mike1corporation(a)gmail.com> wrote: > > Hi everyone, > > I'm figuring out a strange behavoir with OrderedCollection.

Implement Matrix whith OrderedCollection

by frankl1_miky

Hi everyone, I'm figuring out a strange behavoir with OrderedCollection. Actually I've created a matrix using OrderedCollection like this: /c := OrderedCollection new: 16 withAll: (OrderedCollection new: 16 withAll: 0). c./ But when I try to set the value at row 1 and column 2 to be 50 like this: /(c at: 1) at: 2 put: 50/ I instead get 50 in any cell of the second column and I don't know why. When using a Matrix and the massage at:at:put, the behavoir is normal. Why that strange behavoir with OrderedCollection? -- View this message in context: http://forum.world.st/Implement-Matrix-whith-OrderedCollection-tp4945002.ht… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

However, Process is a Pharo user level class, not something private to the implementation of the vm. Any programmer should know what to expect and what to not expect when different Processes are started, and how they behave and interact. It's part of the general knowledge of the Smalltalk programming model, on par with Object, Class and Behavior. So, before I switch to the pharo-dev list, let's wait and see... BTW, it seems that reference [1], containing the charts you mention, could not find its way in your reply. Can you please make it available? Greetings Raffaelo
