High speed trains run on dedicated railways. There is no freight or commuter trains that need to go out of the way. I believe this would be the same for this idea.

There is supposed to be an important new feature in Firefox 21 (which was not talked about in the summary): h.264 playback with system codecs enabled by default. It is present in Firefox 20, but needed to be enabled manually through about:config.

Instead of doing forensics analysis, you might want to RTFA. The image is a reconstruction. It's a montage of other pictures. Of course, you are going to find a lot of discrepancies....

We are probably talking about a wrist watch kind of device, for which a smartphone is hardly a replacement.

The orbit of the satellite seems rather stable so far. The spacecraft itself may or may not have a functional attitude control system, but that's another story. Of course, as often, the slashdot article about it was rather misleading.

It seems that preying mantis cannibalism during sex happens much less frequently in the wild than in captivity.

Almost all bees (except parasitic bees ?) are important contributors to pollination, though. This would mean they have an indirect economical benefit to the society as a whole... which may or may not be taken into account by the bee venom farmers.

All right, calling the rocket launch a "weapon test" was not totally uncalled for, because we all know that space rocket technology is dual use by nature, and can result in the development of ballistic missiles.
But this...
The satellite is just a small spacecraft on a polar low earth orbit. It seems its attitude control system has failed, this is why it tumbles around. It's not the first example of a failed satellite on low earth orbit... and it's not because it is tumbling that its trajectory has become unpredictable. It will just decay in the atmosphere and burn before reaching the ground, as most low earth orbit satellites do at the end of their life. Controlled re-entries are rare, except for massive objects such as the Mir space station.

Being completely surrounded by hazardous rocks does not seem to be an issue for the Dawn mission so far...

This is NOT the Wipeout you are looking for. What a pity.

Yet, you need to have a facebook account. Unlike gmail/gtalk or other jabber services, it is not possible to send messages from facebook chat to other XMPP networks.

Ah, finally !
Thanks for showing us what a real Troll is. :)

It has been done to death for snoozing alarm clocks. I fail to see what is new in this idea. Has this really never been implemented in mobile phones ?

All right, instant sharing from the phone or the camera can be practical. I can see a few uses of it, for party pictures or for lucky shots of your favorite movie star. Still, I can't help but think this is a niche for a digital camera, because it does not really fit in what I see as usual workflow with this device.
Notice that it is rather the same for DSLRs or point and shoots, for semi-pro photographers or families on holidays:
1- Take your camera
2- Go to an interesting place
3- Take many pictures (often too many pictures)
4- Spend time to sort the pictures and keep the best. Optionally crop and modify color balance. 5- Upload them to flickr/picasa/etc (or keep them for yourself)
6- Add titles/comments/captions to the uploaded pictures

Of course, the 4th step takes the longest time of the bunch. The problem is that it would be a pain to perform it from the camera. Even if Android improves the basic tools already available on point and shoots, the screen is still too small, and you cannot do side by side comparisons... So at the end of the day, I can see myself sorting/editing a few pictures from the camera, but not the tens or hundreds of pictures that usually quickly end up on my SD card. The ability to share directly from the camera would do little to help me.
On the contrary, the other prospect that is addressed in TFA is more interesting: using Android to access lower level control of the camera. But I doubt that we will see this feature on consumer point and shoots.
I also find GPS tagging to be an interesting feature, because it helps with the 6th step. But you do not need Android for this, and it still kills battery life.

Can we stop already with these Apple/Samsung trial stories ?

It's not that I'm not interested in the subject: I believe its outcome will have profound implications on the smartphone/tablet landscape (hopefully for the best).
However, I am totally uninterested in every trivial aspect and "twist" of the trial, especially when I'm sure that slashdot editors/firehose cherry pick these stories, and fail to give us the greater picture of the process. Can't we just wait for the court ruling, and have a GOOD summary of it, for once ?
