Re: Mounting USB Memory

Most USB sticks will contain at least one partition. That is standard practice. Some devices don't have a partition table and just use the whole device for the file system. This can give you an extra 0.5KB of storage, or more.

Re: Stuck at boot

Ok, it looks like you are running a plain Raspbian image rather than a NOOBS install. That is not a problem. But do you have anything connected to the P1 GPIO connector? What is happening is that you are booting in "Safe Mode" (The "Greetings from standalone Raspberry Pi" message is proof of this). ...

Re: MySQL 5.6 - will there be an installable package?

I'm sure 5.6 will eventually become part of Sid, and a couple of weeks later enter Jessie. Just be patient. New versions often have issues or new bugs, most of those will have to be fixed before it makes it into Jessie.

Re: When can upgrade to the latest version of openssl & open

Why do you need to upgrade? Is it just because of the Heartbleed problem? If so, it is already fixed. If not, you can download the latest source from Debian Sid and compile it yourself.

Yes, apt-get clean does just clear the package cache. It doesn't touch the index files at all.

Re: USB and Ethernet DEAD!

If the Pi SoC is still functional, and the GPIOs and video out are working, then the "dead" Pi is still useful to some people. It can still be used for the first stages of the Bare Metal "Baking Pi" course. It could play videos as long as they are on the SD card. You can connect a serial adapter to ...

They will usually be a multiple of 3.6v (normal rating for a LiPo cell). Some very old ones were 12v, with 10 NiCd or NiMh cells at 1.2v each. Very heavy they ...

It shouldn't take that long. No more than a couple of minutes. Also, that particular step of the upgrade procedure is using local files and doesn't use the internet at that point. It will only use the internet once it has decided what needs to be downloaded and tries to fetch those files. Does your ...

Re: switches

I'm suspecting the circuit is using a simple push-button switch, which has 4 pins, pushed into the breadboard. Usually on these switches the two pins on each side are joined together internally, and the two sides joined together when the button is pushed. So, it would only need two wires. A picture ...

Re: Suspend Raspberry Pi for power saving

It might be possible to suspend the CPU and shut down the USB/ethernet, but you would need someone who is experienced in writing GPU code to set it to power up again under a timer (does the GPU even have such a timer??). Also, any USB devices connected will still have 5V power and may consume up to ...

I think all TVs sold in Europe in the 90s should have a RCA input , which the Pi can drive with its output. Many in the 80s also had these. Otherwise you would need a TV modulator as used in many home computers and video games of the era to convert the RCA composite video to a UHF broadcast signal....

Possibly a temporary problem with one of the mirrors. Leave it for a few hours at least and try again with "sudo apt-get update" first.
