That should be straightforward using nothing but the IPFS command-line client. But it's worth thinking about the goals. What are you trying to improve exactly? The main advantage that IPFS provides is the possibility to create full or partial mirrors of the data (and thus faster access), including on your personal machine. To make this effective, you have to think a bit about good data management strategies. Few people will want to mirror all the history of Pharo. So you have to make interesting subcollections available under permanent names (via IPNS). Konrad.

I would like something like that for Pharo images. Can you sync files.pharo.org on ipfs ?

I think Marcus was interested to have something like that. yes! IPFS has nice properties for many thingsâ¦ e.g. one simple things to try is to distribute images via IPFSâ¦ it has all the propose of Bittorrent for that.

This is interesting, Pharo VM crashes with segmentation fault on macOS High Sierra when I select the error instance variable from the GTDebugger. crash.dmp attached. On the other hand, I wrote a workaround for others with the same problem and who need a quick & dirty fix.

Re: [Pharo-users] Modeling HABTM

by Todd Blanchard

I've done a couple cheap and cheerful ORMs in various languages. I always punt on doing the relationships because finishing the app is more urgent than writing a whole framework. I just add an instance method that executes the appropriate SQL to fetch the related objects. You can spend a lot of time trying to do this in a generic declarative way, or you can just write a query as an instance method and get on with finishing your app. > On Jun 10, 2019, at 5:20 AM, sergio ruiz <sergio.rrd(a)gmail.com> wrote: > > I am currently putting together a Seaside website for my radio show.
