Thanks Marcus. And thanks Igor! the whole day has been excellent, very understandable (even for newbies like me). I hope the rest of the school continues as good as today. cheers Mariano On Mon, Mar 7, 2011 at 7:38 PM, Marcus Denker <marcus.denker(a)inria.fr>wrote: > Hi, > > Igors slides are now available: > > FFI: > http://dl.dropbox.com/u/2753738/About%20FFI.key.pdf > > JourneyInTheVM: > http://dl.dropbox.com/u/2753738/JourneyInTheVM.key.pdf > > -- > Marcus Denker -- http://www.marcusdenker.de > INRIA Lille -- Nord Europe.

Re: [Pharo-project] OSProcess

by David T. Lewis

I do not know if it applies here, but the plugins might not be interchangeable between Cog and the standard VM. The interpreter proxy interfaces are different, and oscog has changes to an internal data structure in the file plugin then might cause problems. I have not looked at it in detail, so just be aware that there could be problems if you use a plugin from the standard VM with cog or vice versa. Also, IIRC there were some earlier OS X VMs (maybe 5.7.4???) that accidently contained a very old OSPP version, and this version could also lead to a crash on OS X.

[Pharo-project] Fwd: [SqueakDBX] Simple object pool 0.1.1 "released".

by Mariano Martinez Peck

Thanks Panu. This is awesome. We will integrate your info in our website!! :) mariano ---------- Forwarded message ---------- From: Panu Suominen <panu.j.m.suominen(a)gmail.com> Date: Mon, Mar 7, 2011 at 8:28 AM Subject: [SqueakDBX] Simple object pool 0.1.1 "released". To: The complete and open-source solution to relational database access < squeakdbx(a)lists.squeakfoundation.org> Long time ago I mailed that I have started to build new pooling solution for objects because I could not find existing one with tests. Then I promised to improve documentation. It has taken quite long time but now I have created minimal documentation that should enable people to try my implementation. Currenlty it is nothing spectacular. Project can be found at http://www.squeaksource.com/ObjectPool.html the wiki there should get you started. If one has loaded GlorpDBX one could start using pool with following code to start pooling SqueakDBX connections: Gofer new squeaksource:'ObjectPool'; package:'ConfigurationOfObjectPool'; load. ((Smalltalk at: #ConfigurationOfObjectPool) project version:'0.1.1') load:#('default' 'dbx'). SqueakDatabaseAccessor DefaultDriver: OPSqueakDBXDriver. Currently OPSqueakDBXDriver does not restrict the amount of active or pooled connections. I will improve that soon. One can load basic pooling implementation without DBX-related stuff by just executing: ((Smalltalk at: #ConfigurationOfObjectPool) project version:'0.1.1') load. -- Panu _______________________________________________ SqueakDBX mailing list SqueakDBX(a)lists.squeakfoundation.org http://lists.squeakfoundation.org/mailman/listinfo/squeakdbx

Re: [Pharo-project] what's happened to the blogger group?

Hey guys, I've been a bit AWOL the last couple of weeks, family emergency. I was JUST going to say, though - Francois is doing an amazing job with his weekly summaries, much more in-depth than I was planning to. So I highly second the suggestion of creating an account for him. :) Dmitri On Sun, Mar 6, 2011 at 6:21 AM, Adrian Lienhard <adi(a)netstyle.ch> wrote: > > On Mar 6, 2011, at 12:09 , Geert Claes wrote: > >> Francois has posted another nice weekly summary on his blog at >> http://articles.tulipemoutarde.be Â For visibility I thought Dmitri and >> Farncois were to be given access to the Pharo website so they can post on >> the Pharo news/blg area too? > > Yes.
