Does the information all have to be displayed at the same time, or could each page be displayed for (say) 10 seconds? If you could display one page at a time then you could set up several virtual desktops, run the browser full screen showing the page that you want on each of them and use wmctrl to s...

It might also be handy to get a copy of Operating Systems: Design And Implementation by Andrew S Tanenbaum.

This will explain why some things are done in the way that they are.

The RPi team has a git repository which you can copy to your own machine by doing: git clone https://github.com/raspberrypi/linux.git and then explore it by using gitk You can get more information from this than you would than just from the patches alone. I'd guess that's why they don't give "real" ...

I'm planning to use mine for digital voice using Codec2 on V/UHF - the basic outline of my plan is here . The soundcard problem is fairly easily solved with a pair of £5 USB soundcards (unless you are planning to do SDR in which case you might need one high quality card.) There's also a lot of softw...

Good luck!

<t>Isn't replacing ICT with programming a bit of a daft move?<br/> <br/> The only relationship that the two things have is that they both involve computers - to me it's analogous to replacing English with Art since you can do both using pencil and paper.<br/> <br/> Why aren't basic computer skills (...

<t>jacklang said: <br/> <br/> <br/> My guess is that the hobbyist/development market is nearer 10K units than 100K. There are 6300 or so members of this forum, of which perhaps only 600 are active.<br/> <br/> <br/> I've a feeling that you may be surprised, especially if there is a belief that the in...

Ooh, it looks like I made a mistake. I was sure I'd read that the processor on the RasPi didn't have a floating point unit.

In fact, it does have the VFP11 coprocessor. Which makes life a lot easier

<t>Hi Chris,<br/> <br/> As I said, I wasn't suggesting connecting a 1Gsps sampler to the RPi - that would not be a sensible way to do things. However, there's a couple of technical points with your numbers that I'd like to address. The Nyquist rate is 2x the bandwidth of the signal you are sampling ...

<t>WizardOfOz: Does it have to be that way with SDR, though?<br/> <br/> A very simple DDC receiver could consist of switchable front-end consisting of preamp/attenuator and anti-aliasing filter going into a wideband ADC. If we take the TI ADS5400 (the first thing that Google found for me,) it sample...

<t>I'd like to do something similar.<br/> <br/> I think using YU1LM's front ends is a good idea. I'd put them on a board with a high quality DAC/ADC and a dsPic (to do the heavy lifting of modulating and demodulating the I/Q signals to audio.)<br/> <br/> It could even be designed to have a front-end...
