Comment Cubieboard? Re:Count me stunned (Score 1) 91

As far as I know, there is no Raspberry Pi equivalent using the A10.

This is the system I'm watching, http://cubieboard.org/ 1GHz ARM cortex-A8, Mali400, 1GB RAM, Ethernet, USB, SATA, $49. I would need to learn more about both to compare GPIO. From their web page (and links), they've shipped one batch, getting ready to ship another, and larger batch in about a month.

If Cubieboard was available now I would have picked one up, but with the Raspberry Pi upgraded to 512MB and this source code release it's going to be a much more difficult choice with that SATA weighing very much on the Cubieboard side.

It is worse if it must rearrange memory to accomodate the request.

You were going okay until here. You can't rearrange memory, malloc returns pointers, and there isn't any callback to ask for that pointer back to move it to another location.

Byte compiled languages like Java can rearrange memory but you call new not malloc so I know you weren't talking about them. Garbage collection is a much bigger problem especially if you think about mixing Java and real time operations. C/C++ in realtime means following the best practices, but for Java, get a different Java http://en.wikipedia.org/wiki/Real_time_Java.

Comment N900 + bluetooth (Score 1) 158

I'm using my Nokia N900 for in car entertainment, aka podcasts while I drive. Since the radio uses bluetooth I'm using its buttons to control it, but I also used to use a bluetooth mouse I use while on a walk to control it. The mouse could be solder up someway to trigger the three mouse buttons and scroll wheel to send inputs over bluetooth. I don't use a display while driving, and the daylight readable would be a problem for most portable players and cell phone systems. Still since I have it working that's the route I would be taking.

Comment Re:single link dual link with a dual link single l (Score 1) 266

They didn't used to do that. My first APC UPS had a standard B USB port on it to take a standard cord.

If you are observant the cable is a keyed RJ-45, so you couldn't plug it into an ethernet port (an ethernet RJ-45 will plug into the UPS though), and if you are really observant it is a 10 conductor RJ-45 end where ethernet is 8. I haven't decided if they are trying to be extra cheap or make it so that one cable has a USB A port on the other end and a different one has a RS-232, with each uses different contacts on the UPS side. Then again if they were trying to support RS-232 and UPS then the older UPSes would be the ones that might need it not the newer ones.

The lame part is my second UPS came from the store as a bundle, the UPS, a separate power strip, and an extra long USB A to B cord which I was planning to use to put the UPS further away from the computer, imagine my surprise when I got the bundle and found there was no way that was going to plug in to the UPS.

Comment Re:Unfortunately, Nokia has no Steve Jobs (Score 1) 363

$70 doesn't sound like a bad price for the phone you posted, and running on a AA battery is a good idea. But for a car, why spend the money? Use an old cell phone. Back before I bought my first cell phone my mom gave me an old cell phone of hers for that purpose, I just checked and it is 2/3 bars of battery after probably having the last charge three years ago. The trick is to remove the battery before leaving it for emergencies. Being ready to respond to the on button really drains the battery (probably the real time clock), but whatever, the battery will last longer outside of a cell phone than in it even off.

Now that I've bought my first cell phone (Nokia N900 Maemo/Linux) and changing cars that spare phone hasn't made it back out to the car, but maybe it should, after a fresh charge.

Comment don't force 965 minimum width, ditch size bars (Score 1) 410

If my browser's width is less than 965 pixels it gives me a scroll bar preventing the browser from wrapping further even though the the main story is 478 pixels wide. That also means that portrait browsing my cell phone doesn't work because either the text is too small to read, or I zoom in and have to scroll side to side to see every line. Related to the above, give an option to ditch the side boxes completely. You go about an eighth of the way down one day's front page stories and both the left and right boxes run out and from then it it's white wasted space.

Comment hour training, both ways? (Score 1) 171

Aren't they completely missing the point when they list an hour of training? If it takes an hour to understand me enough to translate it into another language it's going to take another hour for them to train to be able to respond (either it requires training for a person or it doesn't). That makes it pointless, good luck finding a local to spend an hour talking to a computer so they can answer your simple question.

Comment Re:Linked story lacking in details (Score 1) 307

In the test vehicles (presumably the ones with red plates), there must be 2 people in the vehicle at all times, with one able to immediately take over control.

Anyone find it a bit strange that they would need a new law in Nevada to do what they've already been doing in California? Or is it intended to keep the home hobbyist out of the market? Why two people for a car that's supposed to be able to drive itself? They say what the one person is supposed to do, be ready to take over control, but the other?

in a manner which brings attention to the issue, but does not disrupt normal operations.

They put a really low bar to get around their block, just disable javascript reload and keep reading! At least that was my first thought when I viewed it and with konqueror it's an easy menu option to disable javascript for the current window. Now it looks like they disabled editing for every english wikipedia article, and that you can't get around.

Comment Re:Can I watch these new applications on TV . . . (Score 1) 107

So what if I haul that old, dusty analog TV out of the attic, switch it on and tune it to one of these new applications? What will I see? Strange, weird pulsating patterns? Or garbled snow and fuzzy sounds?

I would expect it to be similar to the channels that are now carrying digital tv channels. Both an unused channel and a channel that is now broadcasting digitally display a snow pattern, but the digital channel is distinct, still snow, but a different enough pattern that if you see both you can visibly identify the difference. That is unless the analog decoder replaces the snow with a solid color (like blue).

Comment overheated laptop (Score 1) 76

My laptop had been having an overheating problem that wasn't obvious was a heat problem for months. I just started noticing that doing something intensive, yes like compiling the kernel, would cause the CPU MHz listed in /proc/cpuinfo to drop down, sensors listed the temperature going up, but it wasn't obvious what the range or limit was. In the end I went to replace the thermal paste on the CPU, but only got as far as removing the fan and seeing a huge buildup mat of dust and fiber blocking the heat-pipe fins. I removed that and the issue went away. There just isn't any way to see the area what was blocked until the fan was removed, and the rest of the system looked dust free, at least nothing to make me think there was a problem. If you're still reading this Moxie Marlinspike, you might want to check to see if your solution is as easy as mine.
