Is there an business interest of running on ARM processors? Is there a sale advantage of having this? I don't want to sound too inquisitive nor pedantic, those are real questions. As stated in previous mails, running on the platform is a technical challenge per se (I couldn't make it if I wanted), but it's just a very small part of "deploying to Android". And I'm not talking about app stores. Even though Android (AOSP) is Linux based, the memory/battery constraints makes that apps or services lifecycle completely different to regular unix processes. And I don't see how this fits into the whole android environment. Last time I tried (+1yr) it the VM was a permanent process, without access to device sensors, etc.[*] I have a genuine interest in this topic, because my company depends both on Pharo and Android (native) software. But how I see this, the advantage of Pharo running on Android for devices other than phones/tablets, more kind of "internet of things" devices. The advantage is also that the image is an asset of the vm, so you can update your app without having to reinstall it through the platform app management. Please don't let this stop you guys from doing this VM even for the fun/sake of doing it. But as you are making this public, I feel allowed to ask questions and add comments. You can simply ignore them. :) Regards, Esteban A. Maringolo [*] Several years ago I took a private course of "mobile squeak", and even compiled a modified squeak VM for WinCE, running MVC based UIs. Back then Squeak UI was way better than WinCE's, even for "business apps". Now I think mobile expectations changed.

Pharo VM crash on seom DrGeo sketch

Hi, I have some VM crash on some DrGeo. It happens from the DrGeo file dialog when the preview of a sketch is computed. It is repeatable. I saw it on Mac, then in Linux as well. See below the log Hilaire -- Dr. Geo http://drgeo.eu iStoa - https://launchpad.net/istoa

Cloudfork HMAC-SHA256 in System-Hashing

by FranÃ§ois Stephany

Does it make sense from a license point of view and practical point of view to include the CloudFork HMAC-SHA256 implementation (CFSH256 class) in the System-Hashing package (in where there's already SHA1 and MD5) ?

I like the idea of being able to instantiate a VM (SqueakVM.java) inside an Android bound Service, and forward good part of the logic to Smalltalk. But I don't know if the VM can run "headless" (without a SqueakView), or accept "evals" other than from a socket connection. I didn't see any evaluate(String code) method in SqueakVM.java when I analyzed the CogDroid vm back then. > If it isn't precise enough, be more direct :-). You kind of already answered my question, but I was wondering if there was an existing "user" of this new VM, for a specific application or game. And also if this VM was meant just "to run" on Android or also integrate with it. Regards! Esteban A. Maringolo
