Re: [Pharo-users] [ANN] Mathex 0.3 is out! How hard would it be to give the possibility to use it with Pillar?
Nice, I'll take time to implement this feature as soon as I can :).

directly inside Pillar? Mathex provide pdf/png generation under Linux,
so it is possible to create images for non-LaTeX Pillar's exportation.
what about
${mathex:value=2 asMathex sqrt}$
Looks good but does the right part supports multi lines?
the right part ends with '}$'. If there are line breaks before, so be
it :-).

[Pharo-users] Garage with oracle
Does anyone use Garage with an oracle database? Maybe someone that develops on Mac OS? I would be interested in the best way to compile and install libraries in order to use it from pharo. Norbert
Re: [Pharo-users] Would smart variable ordering improve performance?
Glad to hear this. It would be fantastic if the VM would enable such experiment (e.g., relayouting variables and measuring impact on the low level cache). Enjoy Splash!
