"He, along with the engineers I spoke to, said that this launch was much different than launches past. They all said the launch and collaboration felt more engrained in the startup culture. Not only did the team feel like what they were doing was cutting edge and unique, but written in go (code)"

awesome, iiuc, the go code is running in the beacon itself, which means it must be using go for linux/arm?

if it's not using linux, then things will be really interesting.

Re: [go-nuts] PayPal hardware powered by Go bradfitz 9/9/13 5:09 PM
Yes, gc linux/arm, I believe.

And it's either Go tip, or Go 1.1 with cherry-picked changes from Go tip.

*JOY*

I don't suppose anyone from Paypal on the ML can comment on this ?

Josh Bleecher Snyder is mentioned in the article and has contributed to the Go standard library.

(I'm guessing >= 1.1 because he's sent in changes to Go since 1.1 came out)

Thanks for sharing this, Brad. You beat me to it.

Yes, gc linux/arm5. And yes, I'm using Go 1.1 plus cherry-picking.
I've encountered a few arm-only bumps with tip recently that I've not
looked into carefully yet. Don't worry, I'll file issues. :)

Look for a blog post with more details sometime soonish. Once it is
up, I'll be sure to share here.

P.S. Thanks to all, both for the language and for the wonderful
community. Writing in Go continues to be the best part of an
all-around very interesting project. (Bespoke hardware and crypto and
BLE, oh my!)

That would be me. Ask me anything. I'll answer as much as I possibly can. :)

I don't think we'll ever be able to put a stake through the marvel
kirkwood chipset, that thing has more lives than a cat.

How well does Go play with low-memory systems? From playing with Go, it seems to me that it would be an awesome language for embedded development, but that GC could cause problems with limited memory. Did you write a custom malloc? How well did it interact with the threading model?

You're kind of the godfather of the ARM version of Go, aren't you? I guess congratulations to you and all other ARM contributors are in order, this looks like quite an endorsement.

Hardly, I'm kind of an uncomfortable Uncle.

It has been surprisingly smooth sailing (although I am looking forward
to precise GC).

Hi Josh,

Sure sounds really cool indeed! The thing that triggered me the most, was the BLE part :) Is there anything written in Go that you are using to communicate with BLE hardware? Do you have knowledge of any Go packages or do you have any pointers?

Thanks so much for your time!

Cheers,

Sander

Hi Josh…

After googling (once again ;) I found your talk of last GopherCon: http://confreaks.com/videos/3423-gophercon2014-embedded-go-and-bluetooth-low-energy-hardware

Great talk which seems have a whole bunch of pointers to get me started… So thanks and of course I’m always open to even more pointers if you have any!

Cheers,

Sander

Glad it was helpful! I'd say that the best thing to do at this point
is experiment and ask questions if/when you get stuck.

Will do... Thx!

Slightly related to this, I just created a new package (https://github.com/raff/goble) that aims to implement support for BLE for OSX.
It's basically a port of nodejs noble/bleno and my intention was to add it to gatt directly, but right now gatt is a little too much "linux only".

If we can figure out a way to make it more platform independent (maybe do it like noble/bleno and move the HCI stuff in a "linux" package) I'd be more than happy to contribute directly there. Otherwise once I have a few more things working I may try to do the "reverse" (make my code generate the same data that HCI generates and plug it in as a "darwin specific" shim, or something like that).

That's great! I started playing with the XPC stuff but got distracted
by my looming GopherCon talk. :)

I'm very open to moving the HCI stuff into a separate package. And I
do think for reasons of (enforced) interface compatibility that it'd
be better to have a single home for this stuff. I'd welcome pull
requests.
