I constantly switch between using two external monitors through my docking station, using my TV through HDMI, or just the internal display. I don't even have an xorg.conf file. The defaults are perfectly fine and RandR does the job of chang

There's no BIOS on ARM. BIOS is x86-only.

Two other things: * ARM's big.LITTLE promises to drastically reduce power consumption under low CPU load. It seems unlikely Intel will be able to offer something similar anytime soon. * If you compare Atom Z2460 with SoCs based on Cortex-A1

Older versions of Chromium work just fine on ARM. For example the ARM port of Ubuntu provides Chromium 10 packages. I remember reading that newer versions don't build, but I don't know why.

I should have started with a disclaimer: this was 3 years ago and I don't perfectly remember all the details. It was a system cron job, not one added by me. I think it was logrotate. I've removed it, but finding out what was happening wasn'

I've tried something like that in the past - I've used ruby on Linux to program a robot, with I/O piped through an Arduino. It was painful . I've ran into lots of timing issues. The whole thing was incredibly unpredictable. Disabling the g

Okay, knowledge of this specific optimisation wouldn't be that useful except in some very unlikely scenarios. Nevertheless, I found this to be an interesting read about some Ruby MRI internals. But I have to disagree with your attitude towa

As far as I can tell, the only problem is that the encryption layer won't forward TRIM commands to the SSD by default because that can reveal some information about the data layout. I've been using full disk encryption on an SSD for a year

Well, I remember them mentioning late November as a likely time to start shipping boards. You'll find some references to this on their [FAQ page]( http://www.raspberrypi.org/faqs ). We're in late December and they haven't even sold the beta

I've never heard of the allwinner A10 before, and it looks great on paper: 1.5ghz Cortex-A8, 1 GB RAM, SATA, 3d graphics and hardware video decoder, and the other usual stuff like SD, HDMI, Ethernet, NAND and various other I/O ports, plus f

For $149 I'd rather get an i.MX53 Quick Start Board with Cortex-A8 @ 1 GHz / 1GB DDR3 RAM / SATA(!) / 1080p video decoder / VGA / Ethernet / USB. I agree about BeagleBone, it's a great choice if you don't need video or too much RAM, and it

Yes, not all ARMv7 instructions meet the Popek/Goldberg virtualization criteria. The project I'm working on uses dynamic binary translation to trap & interpret these instructions. This is how VMware works without virtualization extensio

I'm going to guess that by 'no virtualization ability', you probably mean no hardware acceleration for virtualization. That doesn't mean you can't have OS-level virtualization. In fact, I'm working on a hypervisor for BeagleBoard. Plus, Tru

I find it strange that they're using Cortex-A9 CPUs. I would have expected anyone going for the server market with ARM cores to use Cortex-A15, which has 40 bit addressing with PAE.

by lgeek 15y ago
Also useful to remember that A15 and A7 are binary compatible and that these are the only cores which support LPAE.

Yes, you can record sound from the built-in microphone. The app I have seems to record 3gpp @ 8kHz, 12.8 kbit. No idea if you can record with a higher sampling rate. I haven't used it before, but the recording sounds way better than a typic
