News for hackers. Stuff that matters.

A comment on Sun Small Programmable Object Technology Project (2007).

Can't believe that Sun SPOTs made it to Hacker News after all this time. I run the mirror site mentioned here, and still have a few drawers full of SPOTs (as well as a couple of complete kits in the boxes.

I was just talking to someone the other day about resurrecting the Squawk VM and porting it to the Cortex Mx architecture. It really was ahead of its time.

Due to your remark, I have found this https://github.com/tomatsu/squawk

I think another alternative would be microEJ, I guess.

80-100k SRAM is still a pretty steep tax for most Cortex Mx parts, though not the largest.

Given the kind of applications I was able to write in 640KB, there might be still enough space available, even after taking 100k away.

By the way here is a port to ESP8266, MICROBIT, LPC1768, NUCLEO_L476.

Lots of the Cortex M4 parts have less than 100k SRAM total. That '476 is relatively big with 128KB SRAM. The LPC1768 has 32KB, so maybe things have been really slimmed down than I remember.
