You might want to try SimplePersistence, also maintained by Torsten. Pure Smalltalk, uses Fuel, no FFI. http://www.smalltalkhub.com/#!/~TorstenBergmann/SimplePersistence

Section 5 of RFC 3968 explains in details how to do that. This will have to be added to ZnUrl or to a helper class, but that will take some time.

Re: [Pharo-users] Pharo on Raspberry Pi 2

Thierry, Pharo runs in the previous RPI, the problem actually is not more horsepower but a JIT VM. I think Tim was working in that, but the VM is not quiet there yet. >From my experience, Pharo at this stage is only barely usable. But if the VM was similar in specification to that of the x86 architecture I can bet that Pharo will run perfectly well doing some tricks. cheers *Lic.

[OT] Two questions about coding with Amber

by Sebastian Sastre

Hi there! I hope this not get too off topic here but I consider Amber and Pharo to be kind of best friends and we need more data/input for this to improve the development experience. Did you tried or use Amber <http://amber-lang.net/>? We want to have some insight and understand better this two basic things about how Amber users use it to code. If you use Amber or have used it for any purpose (including trying it out), please answer this: http://goo.gl/forms/DZ2djBRW9E <http://goo.gl/forms/DZ2djBRW9E> I'm going to share results after we close the poll. Thanks!
