try out ntpd. That queries a timeserver regularly, and instead of changing the time, it changes the speed of the clock, so that after a few queries it should keep in sync.

They didn't patent videogame-emulation, they patented RUNNING an emulator that utilises certain specific techniques, worded very specifically to dodge the prior art. The patent also cites a long list of emulators as prior-art, so you can be reasonably sure that the specific things of what they...

By the time swap kills your card (should be at least a few years, assuming decent wear-leveling), the card'll be practically worthless anyways, so just buy a new one by then.

Then change PA to work well with Pandora's controls. The UI is built in QAML, which is a css-like language.

MLC NAND Flash memory (which is what's used in most, if not all, sd-cards) typically has ±10.000 erase-cycles. 100.000 is what the more expensive SLC does. Assuming perfect wear-leveling, a 8GByte-card with 20MByte/s sequential write-speed can be killed in 8GByte*10000/(20MByte/s) = 4000000s =...

I've read a report a couple of years ago that putting pictures of your children in your wallet will significantly (±50% iirc) raise the chance of getting it back in case you lose it. Doing something similar with your Pandora should have a similar effect, though it obviously won't protect against...

For a comparison of how much java/Notch's coding sucks: there's even a well-functioning Minecraft-clone for the NDS... But even while those clones run a whole lot better, I still want the real Minecraft as you can't play on minecraft-servers with anything else... Minecraft has become a whole...

Actually, the Omap3530 has a 4-port usb-hub built-in. But utilising that requires some additional chip. But USB2 has pretty high latencies, and idle-power-consumption. I Myself would prefer 2 compact-flash slots over SD. Those are faster, bigger, and probably more reliable. And a DisplayPort...

The extreme III hasn't been in production for quite a while. Sandisk gave it a UHS-1 30MB/s-mode and relabeled them as Extreme, and then, when they introduced the Pro, as Extreme HD Video. Their performance is practically the same, and I can't find any difference between class-6 and class-10...

The framebuffer and the 3d-renderer are separate pieces of hardware. TI has written an open-source KMS-driver for the framebuffer (and got it included in linux 3.3's staging-area, but without any support for using the SGX...), and the SGX-driver is a user-space library, that doesn't require X to...

Well, TI also created a Power Estimation Spreadsheet, for a "hot" CPU. In there, I can get a more reasonable 370mW just by setting it to OPP1 and disabling the screen, with 10% CPU and 30% DSP-load. That should give it 40 hours.

As for audio, TI mentioned 22mW when using the DSP in this document. I doubt we'll ever reach that, but that'll give 28 days of music...

Well, there's a DSP in there that can handle 480P(the screen's resolution) H.264 Baseline without using too much power, but that requires setting aside 64MB of the 256MB available (even when not in use), and the main OS doesn't support it. I can find packages for Gentoo though. The Pandoras...

Let's see: some reasonably complete OS MUST sit on the NAND. It IS big enough to put a (cleaned-up and stripped down) mainstream Distro on there, so there is NO reason to force the use of an SD-card. Forcing the use of an SD-card means maintaining 2 OS's. Such an OS can be copied over to an...

@atari_eric: take a look at the benchmarks I posted. Most class6+-cards max out the sd-card's bus-speed in sequential read/write and random read, but there's only one (tested) card with a decent random write-speed, which matters a lot for OS-purposes: the Sandisk Extreme.

Most actual libs (the .so's) (especially the ones without BC) aren't that big, and many versions of the same lib can fit on the NAND. Besides, it's only for PND-backwards-compatibility, so they could also be put on the same SD-card as the PND's. Libpnd can be made to detect needed old libs and...

Breaking libs is trivially solved by just keeping the old libs around (well, almost trivial, as some libs don't like it when you load multiple versions of them in the same process, which can happen if a library you depend on loads in a different version of some lib than you do...) So yes, if...

No. The Pandora's max throughput is 25MB/s, and most, if not all, UHS-cards have low random write-speeds, which is caused by them using multiple flash-chips in parallel, thereby raising the minimum i/o-size. The best/fastest card to get is the Sandisk Extreme (also called extreme III, and...

Age doesn't make it a great distro. for starters, it's very basic, and its repository is minimal. Oh, and it's built using OpenEmbedded, whose BitBake-recipes could be Gentoo ebuilds...

A pretty complete linux-install DOES fit in the NAND, so there's no reason not to. Requiring the use of an SD-card, even for basic usage, just complicates matters: First of all, a run-of-the-mill sd-card will feel quite slow when used for os-purposes. The best choice is a sandisk extreme...
