Re: Which kernel

<t>Well, I am OpenEmbedded user and I do build custom kernels. Sometimes to have a need to modify, customize, tune the kernel, add new things, which yet are not available in mainline kernel. I would expect myself to building a custom kernel for R-P.<br/> <br/> I would hope, that anything needed (pat...

Re: Intel X86 SOC to compete with ARM

At least tablet version with Android 4.0 was working extremely smooth and that's hard to see in these days. Definitely would like to a with some dev boards if such will be avai...

Re: Cluster (Bramble...) Design Discussion (Advanced)

Well, it would be nice to run N number of virtual machines based on Linux on R-P. Someone did that with Gumstixs to create a virtual network of 1 million [virtual machines] machines for network analysis or something.

Re: Bramble cost estimates

<t>If it is possible drop SDHC from your list. Use networked storage and networked boot. This is gonna save time and money. Nodes are pure computational nodes. Nodes would be easy updatable with the latest software just by doing restart on each node. Node can be lost, but the storage is never lost.<...

Re: [Request] Please add some more Ram, they are really cheap right now.

<t>@tufty, for developer machine you would probably go with 4-8GB of RAM, 8GB currently becomes the norm (it's quite cheap, ~$50 for 8GB DDR3). Even more RAM might be a good idea, but that depends on what you are developing.<br/> <br/> 256MB is fully enough for Linux usage. I am currently running Li...
