They knew it was an issue. Did they know it was going to kill someone? I'm not sure. I guess a lot of people here are software engineers... If you have a button in your phone app that's a bit slow to make something happen, you mig

It's not sarcasm, I'm just very surprised that everyone's opinion is so one-sided about this. I think if you put yourself in the engineer's position, he probably didn't believe that having a switch that was a bit ea

I'll probably get flamed, but... I'm shocked that everyone here is so against GM on this. Given the complexity of a car and all the things that could go wrong, this is a very minor issue. The brakes still work (no ABS though), ste

I'm the guy behind this - I just woke up so I'm a bit late to the party :) It's really good to see a decent discussion here... For me, it's about getting the right tool for the job. I'm mainly a C programmer, but if

It's not strictly NodeJS based - According to their site it runs on top of Lua... There's also another JavaScript microcontroller crowdfunding at the moment: http://www.kickstarter.com/projects/48651611/e

Sorry for the late reply.... At the moment I've got the KickStarter board down to 4mA when idle (as it can sleep) - when executing code I think it's around 40mA. Hopefully by release time I'll have sorted out a few glitches a

There's Beaglebone, Raspberry Pi, and also now Tessel that do that. The previous two have had node.js support for ages but I think have been lacking any kind of real advertising because they're more general purpose. All of those a

Thanks! As I understand it, Tessel uses a version of node.js (and probably Linux underneath) so it needs around 32mb of RAM (and quite a lot of Flash too). I've worked pretty hard to get Espruino running in 8kb (with space for variable

Espruino does use reference counting, and currently falls back to proper Garbage Collection if available memory gets filled with cyclic datastructures. Responding to IO is handled and timestamped using interrupts, so if you write your code

This should work on the larger Arduino boards (the Due and 2560) and it already works on a bunch of other hardware too. To be honest the new board is just to do something a bit different - and to give backers of the KickStarter something fu

Johnny-Five requires a PC (it runs JavaScript on the host computer). On Espruino you can program it, then unplug the PC and it keeps working. One of the big benefits (apart from running on its own) is that you don't have the latency of

Hi, I'm the guy behind it... Just wanted to stand up for it a bit - the -uino postfix is really because of the hobby electronics association. I wanted to do something a bit different by adding the prototype area, and I found the Arduin

To be fair, the Espruino JavaScript interpreter manages this pretty well (in around 8kB of RAM). http://www.espruino.com

I've been working on another embedded JavaScript project - first posted on here almost a year ago, and soon to go on KickStarter: http://www.espruino.com This is really interesting though. It looks like they've got lin

Thanks - that's a really neat solution - however presumably someone would complain if I called that 'Open Source'? I think most people will be smart enough not to care as long as they can legally do everything they want to do with the sourc
