(ie like you would with a "normal" linux box). Ignoring all the app details, if I have a piece of code that's like this: import serial ser = serial.Serial("/dev/ttyUSB0", 9600) while True: print repr(ser.read()) Then on a normal linux box, I'm getting back values I'd expect. On the raspberrypi, I'm simply getting back "\x00" characters. In my actual code, I'm both sending and receiving data. The curious oddity here is that I appear to be receiving the correct *number* of characters, and appear to also be sending the right number (based on the flashing of the RX light on the arduino). However, whilst they're the right number of characters, the actual characters, being NULLs, are clearly wrong. I'm guessing that this is actually nothing to do with python and more a driver issue on the Pi, but on the off chance it is a python issue or something someone else here has seen before I thought it worth posting and asking. If anyone's interested, the context of this is using and RFID tag reader (plugged into the Pi - which I have working to cause motors to spin on another device. The reason for the arduino here rather than faffing with the Pi's pins is a) it'd be faff with the Pi's pins b) I have an arduino with built in servo control circuits - essentially an Arduino duemilanove clone with a motor shield combined c) I had all the bits and really didn't expect serial connection to/from the Pi to be where I'd get issues!

For example, I have a rather nice IBM USB keyboard, if I use that at the same time as a USB wifi dongle, the wifi stops working. A cheapo Kensington keyboard works fine.

Excellent point - I'd forgotten about strace for some reason. Would make an awful lot of sense here.

So I'm pretty sure power isn't the issue (but can't rule it out). I wasn't aware of the more recent debian image. I'll try that before hunting around in strace output - much appreciated! Michael.

The Early Bird rate is available until 12 August, and there is a Concession rate available for Students, Nurses, and Unwaged right up to the conference date. PyCon UK runs from 28th September to 1st October, with the core conference being 29th-30th September, and the venue is, as last year, the Coventry TechnoCentre, easily reached from any part of the country. This year we're running sprints as an integral part of the conference, instead of being tacked on afterwards. Each sprint will have an Introductory talk on Friday 28th, then have sessions throughout the weekend, which you will be able to drop in to between any talks you can'r miss. For the sprint diehards, sessions will continue into Monday to wrap up any loose ends. Hoping to see you there! The PyCon UK team. -------------- next part -------------- An HTML attachment was scrubbed...

But there are still a number of drawbacks, and with virtual machines becoming the unit of deployment, its benefits are less clear. This talk will look at using virtualenv for deployment, and explore some of the limitations and open questions."

We're looking to you, the community, to help us make PyCon 2013 even better. We're accepting proposals through September 28, hoping to break last year's record of 519 talk, tutorial, and poster proposals. We're looking for all types of presentations from all types of people. If you've got a topic to share, we hope you'll submit a proposal. Create an account at https://us.pycon.org/2013/account/signup/, and fill in your speaker profile and submit away! With another record submission period expected, we're also rounding up volunteers for our Program Committee, the team tasked with evaluating the proposals and coming up with the conference schedule. If you're interested in volunteering, join the PyCon Program Committee mailing list and introduce yourself at http://mail.python.org/mailman/listinfo/pycon-pc. Without sponsors, PyCon wouldn't be possible. They're what keep the conference prices low and values high, and we share the same deal with our sponsorship packages. Especially after you factor in the price of tickets that all packages include, we think our sponsorship packages are second to none. We even have a 50% discount for small businesses! Check out https://us.pycon.org/2013/sponsors/whysponsor/ for more info. We've also made changes in how we're doing ticketing, specifically for early bird rates. We even cut our student ticket prices in half, starting at $100! We'll announce more details as we get closer, but know that ticket sales will be opening up in the fall. Be sure to plan accordingly because we anticipate another quick sell out! Be sure to follow us at http://pycon.blogspot.com/ and https://twitter.com/pycon!
