Re: Is this real? - Raspberry Pi Model B+

Well, they didn't wrote if the USB can use 0.5A as per specs. GPIO power limit is also interesting.

5V 2A power supply requirements suggests fully powered USB, and maybe also more power on GPIO.

Re: Raspberry Pi laptop

Thanks for the feedback. I realize you'll never be able to customize a laptop quite like a desktop, due to real estate, but it seems like an opportunity to design a new laptop base that makes it simple to change out single board computers like RPi, Hummingboard or BananaPi, since they're becoming m...

Re: Raspberry Pi laptop

There is no and will be no (usable) Android on Raspberry Pi. The generation of this ARM is just to old. From a consumer point of view there is no need for a laptop with ancient hardware that can't run Windows and/or many Linux apps with even acceptable performance. There are Atrix Lapdocks which are...

Re: Graphic drivers

There is no OpenGL support. You have OpenGL ES. There is a binary blob and open source drivers. Broadcom did release open source code that eventually will replace the binary blob but it's not there yet. Now - do you really have to interface it at a low level. Maybe one of GUI/display libraries would...

Re: why does Midori suck up most of the CPU

GMail has a lot of JavaScript and background connections for example. Raspberry Pi doesn't have strong CPU so it's easy to get ~100% usage even with one application. Empty idle browser shouldn't generate noticeable usage.

Cubietruck is big, Cubieboard 1/2 has very similar size to Raspberry Pi. Beaglebone Black is also almost Raspberry Pi size. PcDuino is much longer, similar to Arduino Mega.

Reddish area is when red is very high and blue/green very low. You could set some minimal ratio of red to green/blue.

That will be rather very hard without distinct look and feel. A lot of openCV code will be needed and on image only it may not be doable (for a robust system).

Chinese stores have them cheap too. I wonder what RK3288 will bring.

Any more advanced IDE will lag on Raspberry Pi. It's way better to do development remotely. On RPi you could use some code editor (Kate, Gedit) and integrate a debugger within the code (pdb or alike).

Re: Best performance for raspberry pi as a vdr platform?

encoding signal to media file may be the cause of high CPU load. That USB dongle has to do some work too. Did you checked what exactly is causing the CPU usage (dongle playing, not playing but recording, copying some big file to /dev/null or other device) ?
