If you are going to use ntfs then you want to install the ntfs-3g driver. This is required to get full write access to ntfs devices.

I will be very surprised if any flash based sites work. Gnash tries to support flash but not really to any usable level.

Re: Samba Install Problems

What format is the USB disk? The default drivers for NTFS built into Linux give read-only access so I wonder if that is your issue. If you install the ntfs-3g driver then this gives full read-write access to NTFS disks.

Re: HDMI problem

The keyboard being bluetooth might be a problem unless it is permanently paired with the dongle so the Pi does not have to handle the bluetooth. If you can get hold of one I wold try a USB keyboard until you get things setup and add the software for bluetooth and configure it for your keyboard.

Re: USB HDD not auto mounting

Under Linux you can mount devices anywhere.

By tradition it seems that /mnt is typically used for drives that are always there and /media tends to be used for removable devices. However this is only a convention and no rule that says it has to be done that way.

Re: Best SD cards for 24x7 use

If you want the most reliable operation there is an excellent case for holding the root file system on a USB stick and only use the SD card for booting. The very nature of SD cards is that they have a limited (albeit quite high) number of write cycles they can support. You can get micro USB drive th...

Re: Shut down via a smart home controler via telnet

Exactly what makes you think it is failing? A point to note is that the Pi can not fully power down (so the red power light goes off) - it can only close the OS and put the Pi into a halt state that needs power on/off to restart. In that mode it is still consuming some power (although slightly less ...

Re: Can't see the internet from RPI

What is the output of the 'ifconfig' command on the Pi? It sounds as if the gateway address may not be found? Also is name server address defined? It can also be worth doing a 'ipconfig' command from a command prompt on the PC to get comparable output for the PC that works.

There should be no real problems copying files to a correctly mounted USB drive - I do it all the time. I can only think you have to mounted the drive correctly.

Re: Challenge: Bitmap comparison

It seems to me that if you used something like the raspistill application to save images to files then you could use the 'cmp' command to compare two saved files as that returns an exit code telling you if two files are identical. If you tried that manually then you would be able to test if two cons...

Re: Pre-purchase questions.

A partial answer to your questions!

Flash is a dead horse on the Pi so if that is one of your requirements then the Pi is the wrong device. There are attempts (e.g. gnash) to provide an open source equivalent, but it is buggy, incomplete and suffers from terrible performance.

What is the power supply you are using rated at? This can be a symptom of a power supply that cannot provide sufficient current as loading the GUI increases the total current required.
