Re: Watchdog monitoring eth0?

An easy way to monitor connectivity is to write a simple bash script that checks if you have network access every x seconds.. You could use the ping command against a website like google.com -- send 4 messages and expect atleast 4 back -- if you get less than perform your network-disconnected behavi...

Re: Concern trolling

<t>The Rpi foundation has been doing a very good job communicating with the community. I am truly impressed at how cool they have stayed, despite all these bogus requests and remarks that they had to deal with. It is a complex process to make this Rpi board and release to the public, and I think tha...

Re: "Real-life" bandwidth available on the USB controller


Theoretically USB2 has a bandwidth of 480Mbits/s ~= 40MBytes/s.


480mbits = 60MB/s So the max bandwidth theoretically is 20MB/s higher then what you stated. Though realistically i've seen it max out for my usage at about 40MB/s for USB 2.0.

Re: wi-fi card for sale

I take back what I said. It looks like there is solid Linux support for it.

Re: wi-fi card for sale

Is that card compatible with ARM-Linux?? A quick search gave me mixed results — seems like you might need NDISWRAPPER to make the card work with linux. However, NDISWRAPPER, unfortunately, does not exist on ARM based computers like the Raspberry Pi.

Re: How to protect the filesystem without a save shutdown button?

<t>What you could do to prevent this from being a problem at-least with software, is to un-mount any connected disks before disconnecting the device from power.<br/> <br/> If a student simply pulls the plug to turn off the device, then the file system "may" become corrupted, however ext3 partitions ...

Re: Python Libraries

PyGame should be able to run in the framebuffer, since after all PyGame is an SDL wrapper for python. Though, PyQt would be a better choice for GUI applications i'm sure.

Re: Auction of boards

Haha that\'s a great way to store up money. I have that problem where I need to buy every new and shiny piece of technology =p.

I\'m thinking of joining the auction too, curious to see what kind of prices the different numbered boards will get.

Re: SDL for PyGame without an X server

<t>Since Raspberry Pi is limited in ram and the X server does not have the proper drivers written for yet it, then it would make sense to have some way of writing games for the console frame-buffer.<br/> <br/> First we need to have a compilable framebuffer driver loaded by the Kernel. It probably ex...
