Re: ethernet cable?

If your thinking Cat5 v Cat 6 get Cat5 it's cheaper, and your pi can only handle 100Mbs, so why pay for GbE? my .02 John Cat 5 doesn't preclude the ability of GbE. You can run a Gigabit Ethernet network on Cat5, Cat5e, or Cat6. Ahh I was getting confused with the standard. I knew there were cat 5 c...

Re: Ethernet communication to network

you could easily enable SSH communications to your pi and then use a software like PuTTy or WinSCP to transfer the files. Is this the kind of operation you were talking about?

Re: Problems reading file

As an update:

I've gotten python (2.7 btw but I don't think it should matter) to write to the same file, but am still unable to read the file.

I'm on a windows8 atm, but will be putting the code on the pi

Problems reading file

By all indications I should be able to read the file in the attached image below. I know that it is pointing to the right file, but I can't manage to get it to read the file and output the text of the file. I'm certain it's a simple problem, and thank you for the help.

Then from here open up the file with your favorite browser and see what it looks like... I do all my HTML o...

Re: Does the HDMI output have enough power for one of these?

While I can't say for certain because I don't have your setup I would err on the side of yes it can run. The only problems I've run into with dicey connections, and subpar performance from the pi is when I was using a severely underpowered PSU (once I switched from 400mA to 700mA all my problems wen...

Re: power from powered USB hub

This is normally true of powered hubs, and there is no harm being done to the pi. I do not know of a way to stop it from backpowering, however you could see if your normal PSU was supplying power by taking a multimeter and checking the voltage at the micro USB.

Hope this helps

Re: programmes not starting

While I am not sure if this will solve your specific problem I have a similar trouble, and I did need to rewrite the image to my SD card. You should try doing a solid reboot first, because this may help.

There is an article that starts on page 19 on how to print using CUPS. I haven't done it myself, however I'd hope this would be of some use (granted this is not how you started your project).

I'll start out by saying that I'm not sure if the Pi can do what you are asking of it but I can answer a few questions. It runs on different forms of Linux with the main ones being rasbian, and Debian which I find most similar (in appearance) to Windows XP but are by no means compatible or even simi...

Re: how to atuo login to raspberry with root

You don't want to boot in root unless you know every move you are making, which you likely don't if you are asking this question. The power of root access has lead many to folly (myself included) so it is simply not a good idea.
