Re: [Pharo-users] MOOC offline download

by Stephane Ducasse

The github folder contains just the source. Yes I will do a iso image and put it. Now it will be around 10gb. I got a script that is called starterKit that should be updated and collected all the resources to actually build the iso. I was looking for a service to produce DVD. If people want to help this is the moment :) On Fri, Apr 28, 2017 at 7:23 PM, Ben Coman <btc(a)openinworld.com> wrote: > > > On Fri, Apr 28, 2017 at 5:11 PM, Stephane Ducasse <stepharo.self(a)gmail.com > > wrote: > >> Hi ben >> >> I do not really get the request? >> Because people can download the file and the portal. >> > > I could not find a whole zip file of entire course, only the individual > files which would be a pain to download, > and did not know of the git repo.

Re: [Pharo-users] Voyage - collecting data from Mongo

by Ð¥ÑÐ¸ÑÑÐ¸Ð½Ð° ÐÐ¸ÑÐ°Ð¹Ð»ÑÐº

Hello, Holger! When I'm using MongoTalk in Pharo 5 and MongoDB 3.4 I can only get a list of existing databases, using command Mongo default open databases. But when I want to get some database's collection (Mongo default open databaseNamed: 'SomeDatabase') collectionAt:'SomeCollection'. it returns nil to me, although there is this collection, with some data at MongoDB. But when I'm using MongoTalk in Pharo 5 with MongoDB storage for example 2.6 version everything works fine. Even at Pharo 5.0, there are built-in Mongo Browser and it gives the same result - show the only list of databases. What it the problem? Am I doing something wrong?

Re: [Pharo-users] Voyage - collecting data from Mongo

by Mark Rizun

I am running a Pharo3.0 image (with an older Voyage) against MongoDB 3.2. I think I am already using "WiredTiger" as database. If you can reproduce it, we can have a look. The only issue I have seen is Sabines authentication failure with more "modern" schemes. I have Pharo 6 and the newest Voyage + MongoDB 3.4. I successfully connected and was able to add new collections. The only problem was that I couldn't access existing collections created in MongoDB. I don't have access to my computer at the moment, but I will try your first suggestion and let you know how it goes.

Re: [Pharo-users] Voyage - collecting data from Mongo

by Mark Rizun

oh? Is that written somewhere in the Voyage documentation? Sorry, I wasn't very accurate in previous email. Actually, my friend is using MongoTalk/Voyage, and she encountered a problem that it is not possible to work with databases created in 3.0+ versions of MongoDB. Probably this issue is related to new storage types (connection part is fine). MongoDB wire protocol is upwards compatible, so while one might not use the new features yet, your application will work. OK

Re: [Pharo-users] Voyage - collecting data from Mongo

by Mark Rizun

Hi, Holger, thank you, I will try your suggestion. However, I use MongoDB 3.4, and I think that Voyage has support for only versions under 3.0. Am I right? Stef, collection in mongo is a container for documents. For example, here three documents are inserted in collection "inventory": db.inventory.insertMany([ { item: "journal", qty: 25, tags: ["blank", "red"], size: { h: 14, w: 21, uom: "cm" } }, { item: "mat", qty: 85, tags: ["gray"], size: { h: 27.9, w: 35.5, uom: "cm" } }, { item: "mousepad", qty: 25, tags: ["gel", "blue"], size: { h: 19, w: 22.85, uom: "cm" } } ]) https://docs.mongodb.com/manual/tutorial/insert-documents/ Mark 2017-04-30 10:37 GMT+02:00 Stephane Ducasse <stepharo.self(a)gmail.com>: > mark > > what is such collection? > > Stef > > On Fri, Apr 28, 2017 at 11:04 PM, Holger Freyther <holger(a)freyther.de> > wrote: > >> >> > On 28.
