At the same time you will be able to search in those documents which is IMHO not possible with GridFS at the moment If you have something different and those documents are standalone then you are better off mapping a URI namespace directly via your frontend webserver. [1] [2]. If you need references from a ânormalâ document to a GridFS document then there might be a chance storing it via the image makes sense (2nd case). In those scenarios you have two things that need to be stored separately. The normal documents and GridFS documents cannot be stored in the same collection. case 1: If you decide to make two requests from the client the mapping in the frontend server might come in handy. You would store the GridFS document first getting back a reference (id or URI) to it. That you can store in the normal document and store that document next. On retrieval of the GridFS document it is most likely you query the reference in the normal document. That request would then redirect to the GridFS mapped URI which would be served completely by the frontend server. case 2: You want to make only one request for uploading both in a multipart message. This way it will be really difficult to treat both resources separately by the frontend server. In this case there is barely a chance other then the image receives the multipart message and stores both documents. But that wonât be fast and should only be done if the number uploads of those big things is rather small compared to the retrieval of the same. On retrieval time you should do the same as above: map the GridFS via frontend server and redirect from the image to retrieve the GridFS document. So having GridFS support in the image can be useful while developing and for deploying case 2. So Iâll take it back partially :) But remember that accessing GridFS documents in the image is just copying a lot of bytes from one socket to another. Exactly the kind of things it is not good at.

Re: [Pharo-dev] Pharo tutorials

by Tyler Sperry

> what is pharo tutorials? I just ran across this issue tonight after installing the 4/10 build of Pharo 3.0 on a Windows netbook. At first I thought it was a 3.0 beta quirk, but no, things worked the same way when I tried it in a fresh 2.0 image as well. The problem is that users get to the tutorials from the "Browse tutorials" window, which has a different behavior than a window created by the tutorial itself. From World > Help > Pharo Tutorials you are in a browser that won't generate menus for selected text. So if you navigate in the left pane to "Welcome" you see text that tells you to select "PharoTutorial next." and right click your way to a "do it (d)" option. The problem is that you can't actually get *any* right click menu for selected right-pane text. I'm a Smalltalk noob, but not a *complete* noob, so I tried Alt+d and sure enough, I got the next Professor Stef lesson in its own window, where the right click menus work fine. Thierry's guess about read only status doesn't seem to totally explain the issue. You can, for example, pick a random lesson in the "Browse tutorials" left pane and the right pane contents will exhibit the same behavior: select + right click doesn't work, but select and Alt+D/P works as expected (I.e. Alt-p will alter the lesson's text.) I can understand why this subject wouldn't show up for most Pharo users: they are experienced Smalltalkers who use the keyboard shortcuts instead of the menus. Given that Pharo isn't targeting beginners it's not a big deal, but I would suggest the text for that first "Welcome" tutorial lesson be changed to tell the student to use Alt+d or Command+d instead of the current frustrating menu suggestion. The second lesson will appear in something like a normal workspace window, and that's where the option of keyboard or mouse menu could be explained.
