Mike Powell     - 7:20 AM  A:  Eric, everything will work fine.   

________________________________________________________________   

Jay Bhagat     - 7:15 AM  Q:  will the clock be persistent?      

Mike Powell     - 7:21 AM  A:  Hi Jay, no - there is no RTC on board. But if the board is connected to the internet via it's ethernet adaptor, the OS goes and find the time/date from a time server.   

________________________________________________________________   

Brian Schmiedlin     - 7:17 AM  Q:  Will the clock keep time even though the unit is powered off?

Mike Powell     - 7:21 AM  A:  Hi Brian, no there is no RTC.

________________________________________________________________

Mike Powell     - 7:21 AM  A:  Hi Nik, yes, vi is there.   

________________________________________________________________   

Lee Hardman     - 7:19 AM  Q:  Hi Mike, is IDLE bundled with the standard image?      

Mike Powell     - 7:22 AM  A:  Hi Lee, I don't know - I'd need to check.   

________________________________________________________________   

Matt Moss     - 7:20 AM  Q:  Hi Mike, Is the Rasberry Pi's RCA Video output going to be PAL or NTSC format? Thanks!      

Mike Powell     - 7:23 AM  A:  Hi Matt, both and is configurable in a text file.    ________________________________________________________________   

    - 7:24 AM  Q:  when will Fedora be available?     

________________________________________________________________   

Jean-Francois Lagarde     - 7:19 AM  Q:  Hello Mike, a little off topic, but when I ordered the Raspberry Pi on newark a few weeks ago, it said that it would be available for shipping mid-april. This morning I checked my order and it says mi-august. Everything has been delayed?      

Mike Powell     - 7:24 AM  A:  Hi Jean-Francois, I'm surprised at that. Please speak to your local Newark office about this.    ________________________________________________________________   

martijn steegmans     - 7:22 AM  Q:  Does the hdmi port support digital audio?      

Mike Powell     - 7:26 AM  A:  Hi Martijn - yes it does.   

________________________________________________________________   

Frank Buss     - 7:22 AM  Q:  is it possible to start something more comfortable like KDE or Gnome on it?      

Mike Powell     - 7:27 AM  A:  Hi Frank - yes, liight versions exist to give a very impressive desktop environment.

________________________________________________________________   

John Ennis     - 7:23 AM  Q:  Is it possible to ssh into the Pi?      

Mike Powell     - 7:27 AM  A:  hi John - yes it is. In the Debian distro, the SSH server starts automatically at boot.    ________________________________________________________________   

mark goldie     - 7:24 AM  Q:  does the Pi board come with some kind of BIOS control? Also, on connecting the LAn cable, how would one control DHCP registration ?      

Mike Powell     - 7:28 AM  A:  Hi Mark, there is no BIOS, but there is a configuration text file to set up the basics of the board.    ________________________________________________________________   

Jean-Francois Lagarde     - 7:22 AM  Q:  I understand that the board automatically connects to a time server and the internet via dhcp? if we need static ip, I guess we need to modify the sources or is there a way to configure the settings of the Pi?      

Mike Powell     - 7:29 AM  A:  Hi Jean-Francois, you can modify the network settings easily as you would any computer.    ________________________________________________________________   

Andrea Benini     - 7:25 AM  Q:  Is there an I2C bus in the GPIO connector available for external peripherals ? I've made a really easy RTC circuit on I2C bus and I'd like to connect it to the PI. I can supply an RTC if the linux image is able to read it from I2C      

Mike Powell     - 7:31 AM  A:  Hi Andrea - yes there is.   

________________________________________________________________   

Herbert Keks     - 7:30 AM  Q:  Will it be possible to run http://www.tvdr.de/ or xbmc on the Raspberry? This would be the killer app in my eyes. But I'm not sure about the video hw acceleration.       

Mike Powell     - 7:34 AM  A:  xbmc has been shown to work. The onboard GPU supports high resolution, full motion video.    ________________________________________________________________   

gary Paterson     - 7:31 AM  Q:  Hi Mike, what is the default version of python and is python 3 available?

s2. henry     - 7:32 AM  Q:  hi,  what power supply do we need ? (voltage, current, physical size ?)      

Mike Powell     - 7:36 AM  A:  A 'regular' phone charger with microUSB plug will work.    ________________________________________________________________   

    - 7:36 AM  Q:  does Farnell have a rep at the factory?  If so, can they take a picture showing how many units have been built?      ________________________________________________________________   

   - 7:37 AM  Q:  how many pallets of units were shipped back to China when the ethernet jack problem was found?      ________________________________________________________________   

rohan kumar     - 7:38 AM  Q:  Is the Pi overclockable?      

Mike Powell     - 7:39 AM  A:  Hi Rohan, yes it can be via the configuration script.    ________________________________________________________________   

Charlie Godwin-Brown     - 7:39 AM  Q:  Can you get a desktop for your RPi?      

Mike Powell     - 7:39 AM  A:  Yes, the Debian distro contains a GUI that you start with sudo startx. ________________________________________________________________   

bryce foster     - 7:44 AM  Q:  If the raspberry pi is put in an enclosed project box will we have to worry about the ARM processor over heating?      

Mike Powell     - 7:42 AM  A:  Hello Bryce, in my opinion you don't need to worry. The whole board only consumes 2-3W.    ________________________________________________________________   

abi nathan     - 7:49 AM  Q:  what is the maximum amperage the pi can handle at 5v? Thanx      

Mike Powell     - 7:44 AM  A:  Hi Abi, the Pi draws the current it requires from the USB power source. This is typically 500mA-750mA depending on what the GPU is doing.   

________________________________________________________________   

Stéphane Zorio     - 7:42 AM  Q:  Is a Apache server include in the Debian Distribution ?      

Mike Powell     - 7:45 AM  A:  Hi Stephane, I don't know, but you can use a apt-get install command to install it as long as you are on the internet.    ________________________________________________________________   

Stefan Fischer     - 7:42 AM  Q:  is the gpio pin description available?      

Mike Powell     - 7:46 AM  A:  Hi Stefan - look at element14, the pin assignment is there.    ________________________________________________________________   

Richard Blundell     - 7:43 AM  Q:  I'm hoping to add a 2nd network adaptor to my Pi (when it comes) and use it as a logger/filter on my home broadband.  Will this work and can you give me any pointers where to look to set this up (I only had a little Linux use some years ago)?      

Mike Powell     - 7:47 AM  A:  I don't see why this shouldnt work using IP Tables in Linux for example.

________________________________________________________________   

Andrea Gatti     - 7:43 AM  Q:  Hi, I'm a beginner so I want to know if there is any manual or guide online for learning to use and programm the raspberry pi?

Mike Powell     - 7:48 AM  A:  Hi Andrea - look at the various forums and guides that will grow on element14 as time goes by.    ________________________________________________________________   

John Morris     - 7:44 AM  Q:  Can I hook the RPi up to a laptop screen?      

Mike Powell     - 7:50 AM  A:  Hi John, not directly. Only to HDMI TV, DVI monitor or older style  TV. Command line via an SSH terminal is possible using an external laptop.   

________________________________________________________________   

Alessandro Ancillotti     - 7:45 AM  Q:  Will RaspberryPI able to run a webserver like lighttpd?
