Re: Pibow (a colourful case for your Raspberry Pi)

What is this bonus thing? Mine came with a plastic spanner thing and a spare screw / nut; that's all.

I'm very curious!

Re: Horrifying USB error count

Nope, it is just the Lapdock with nothing plugged into the rear ports. Of course, the keyboard and trackpad are connected to the Lapdock's internal hub, but then so is yours.

Disable the Ethernet? Would not be able to go online then. Well, not without a wifi adapter anyway. Kind of defeats the point of having Ethernet really...but don't get me wrong - thanks for the info, I'll look into it!

Re: Horrifying USB error count

Lapdock's own built in battery. I have also used various others successfully - iPhone, generic USB power supply (1 amp), etc. Point is, the Lapdock is a powered hub and there is no power connected to the Pi's USB port, only the Pi's power socket (per the "I made a Raspberry Pi Laptop" thread, the Y ...

Re: Horrifying USB error count

Thanks for your advice, RaTTuS. Sadly this does not have any effect in Raspbian (or the old Debian Squeeze image, either). The USB hub inside the Lapdock seems to be disconnecting of its own accord, then reconnecting. It's like the plug is being pulled then reinserted every 3 seconds. I think this m...

Class 4 SD card speed

Hi

I'm writing an image to a Class 4 SD card using dd on OSX. The reported speed is 218474 bytes / sec. That's about 200k. I thought Class 4 meant a minimum sustained write speed of 4MB/sec? Any idea what is going on? It is still writing after 2 1/4 hours....

Mine arrived today. It's a really solid case, holds the Pi securely and is very easy to assemble. Has a nice weighty feel to it which will help prevent the various cables from pulling it about. Top notch protection that looks pretty sweet in the flesh. I did think a single coloured one would look be...

Why the brackets? This is for JonB or anyone able to answer that question.
Because in C / C++ / Java they are mandated in an if statement. Basically the language syntax dictates it.

As to Python... well, I've never used it. ;)

Re: What's the difference between "=" and "=="?

I don't use Python however = is used to set a variable, == is when you're performing a true / false analysis of a variable. Never check a variable with a single = it may cause a compiler / interpreter to error or to set the variable and pass true. a = 100 if a == 0 then .. (will be false) if a == 1...

Another Pi for sale! Worldwide shipping!

HI all

This is my "spare" Pi that came from RS after the Farnell one was delivered. Sadly I have too many computers in my study (21 at the last count!) and I don't have time for them all.

It's an eBay auction: http://www.ebay.co.uk/itm/300743119801

Rat mate, what about the transfer speed? And that hub is junk (I sent mine back it was so badly made)

Other than that, I'm liking the SSD... What's the boot time like on Debian?

T.
Sound is coming out of the analogue plug on the Pi. I might assume a problem with HDMI if not, but I think the problem is it won't switch to HDMI despite what's in config.txt.
