Hi Juan, Thanks for the great feedback!! Vector engine plugin works in JS, and the do-it error on android was solved!! Also you can see the halos in Android. Rotating a window is possible in both projects. Best!! Agustin On Fri, Aug 14, 2026 at 4:50 PM Juan Vuletich <juan@cuis.st> wrote:

Hi Agustín,

This is very impressive!

I just tried the Android VM on my Samsung phone. It works amazingly well. I haven't been able to run Cuis on a phone in a long time. This is great! Performance is impressive. I get 724 megaBytecodes/second and 40 megasends/second. This is similar to what I get on a RasPi 3B+. Vector graphics plugin claims to be active, although I found no easy way to stress it. Is there a way to get a halo on a morph?

I also tried the SqueakJS, with the provided Cuis image. I tried it both on Firefox and Chrome on a Mac. It starts and the menus and tools seem to work, but I get a primitive failure if I try any DoIt. Is this a known issue? Does it work for you? If so, in which platform / os / browsers have you tested? As I could not evaluate or edit code, I could not test performance. Morphic halos work, but it seems the VectorGraphicsPlugin is not available, as it doesn't show the scale halo for SystemWindows.

Thanks! On 2026-08-10 7:33 PM, Agustin Martinez via Cuis-dev wrote:

Hi, I'd like to share two projects related to Squeak, Cuis, and Pharo.

The first is a fork of the SqueakJS project, which lets you run the latest versions of Pharo, Squeak, and Cuis, and includes performance and UX improvements.

smalltalkjsvm.com.ar

The second is a version of OpenSmalltalk for Android where you can run Squeak and Cuis. It was developed with help from FAST.org.ar.

All feedback is welcome. There's always room for improvement.

Best regards,

Agustín
