Flash Sonar - Echolocation Technique For The Blind

VideoSift v6 (VS6) Beta Video Page (Sift Talk Post)

CrushBug says...

As has been said many times, the top menu mouseover needs a delay. I usually have a bunch of VideoSift tabs open and navigating around causes the menus to overlap the videos.

The site channels and FAQ are now fully available within the header navigation, along with the Search function (which is under Watch).

Account preferences are also viewable and editable within the header, under your username which was added as a tab and when clicked that, it will take you to your profile.

All things missing from the upper right area i always use.

*Easily viewable sift lounge(#) in upper right. How am i gonna know if anyone's in their waiting for someone to join. Removing this will kill the lounge(imo)

*No search?

*Missing the 'Hello, eric3579 (3)'
No place to jump to my profile or view my number of pps. What if i want to promote the video im on but dont know if i have pps. Will i have to navigate somewhere just to check

Aesthetically looks nice and is more appealing in that way.

Personally usability/navigating is what i think is an issue.
Navigating is more difficult(as in more work)
Cant just click on 'discussion' to get to recent comments like you can now(clicking on comments). Have to use the sub menu. Also 'Watch' has to use sub menu to get to a front page(although i do like 'hot' and 'just published' in the menu). Sift talk also more difficult to access. The more difficult to get to the less traffic it will see. Current drop down is much easier then having to navigate to the left hand side to get to the sub menu.

I found myself using my back browser button cos its easier when changing between front page and a video ive clicked on. Right now i don't need to do that(can just click video button)

Also change stresses me out. You know, cos i'm old

Maybe i just need a couple beers.

Doubt - How Deniers Win

I'm guess from you're tone your American, or at least only figure Americans are going to be reading? You note that 'we' can't get to the moon, while Chinese rovers navigate it's surface. You note with alarm what coastal Florida will face from sea level rise, and not an entire nation like Kiribati. When we look at a global problem we can't ignore technology just because it's Chinese, or focus so hard on Florida's coast we ignore an entire nation in peril.

Sea levels aren't going to be fine in 2099 and then rise a foot on the eve of 2100. They will continue to rise about 3mm annually, as they have already for the last 100 years.(on a more granular level slightly less than 3mm nearer 1900 and slightly more nearer 2100 but the point stands). Coastal land owners aren't merely going to see this coming. They've watched it happening for nearly 100 years already and managed to cope thus far. Cope is of course a bad word for building housing near the coast and at less than a foot above sea level. It's like how occupants at the base of active volcanoes 'cope' with the occasional eruption. All that is to say, the problem for homes built in such locations has always been a matter of when not if disaster will strike. The entire island nation of Kiribati is barely above sea level. It is one tsunami away from annihilation. Climate change though is, let me be brutally honest, a small part of the problem. A tsunami in 1914 would've annihilated Kiribati, as a tsunami today in 2014 would, as a tsunami in 2114 would. And we are talking annihilate in a way the 2004 tsunami never touched. I mean an island that's all uninhabited, cleared to the ground and brand new, albeit a bit smaller for the wear. That scenario is going to happen sooner or later, even if the planet were cooling for the next 100 years so let's be cautious about preaching it's salvation through prevention of climate change.

Your points on food production are, sorry, wrong. You are correct enough that local food growth is a big part of the problem. You are dead wrong that most, or even any appreciable amount is to blame on climate change now or in the future. All the African nations starving for want of local food production lack it for the same reason, violence and instability. From this point forward referenced as 'men with guns'. The people in Africa have, or at least had, the means to grow their own food. Despite your insistence that men with guns couldn't stop them from eating then, they still did and continue to. A farmer has to control his land for a whole year to plant, raise and harvest his crop or his livestock. Trouble is men with guns come by at harvest time and take everything. In places like the DRC or Somalia they rape the farmer's wife and daughters too. This has been going on for decades and decades, and it obviously doesn't take many years for the farmer to decide it's time to move their family, if they are lucky enough to still be alive. That is the population make up of all the refugee camps of starving people wanting for food. It's not a climate change problem, it's a people are horrible to each other problem. A different climate, better or worse growing conditions, is a tiny and hardly worth noting dent in the real problem.
CO@ emission restrictions do not equate to global economic downturn, they could just as easily mean global economic upturn as new tech is adopted and implemented.
I stated meaningful CO2 emission changes. That means changes that will sway us to less than 1 foot of sea level change by 2100 and corresponding temperatures. Those are massive and rapid reductions, and I'm sorry but that can not be an economic boon too. I'm completely confident that electric cars and alternative or fusion power will have almost entirely supplanted fossil fuel usage before 2100, and because they are good business. Pushing today though for massive emission reductions can only be accomplish be reducing global consumption. People don't like that, and they jump all over any excuse to go to war if it means lifting those reductions. That's just the terrible nature of our species.

As for glaciers, I did read the article. You'll notice it observed that increasing the spatial resolution of models changed the picture entirely? The IPCC noted this and updated their findings accordingly as well(page 242). The best guess by 2100 is better than 50% of the glaciers through the entire range remaining. The uncertainty range even includes a potential, though less likely GAIN of mass:
. Results for the Himalaya range between 2% gain and 29% loss to 2035; to 2100, the range of losses is 15 to 78% under RCP4.5. The modelmean loss to 2100 is 45% under RCP4.5 and 68% under RCP8.5 (medium confidence). It is virtually certain that these projections are more reliable than in earlier erroneous assessment (Cruz et al., 2007) of complete disappearance by 2035.

If you still want to insist Nepal will be without glaciers in 2100 please provide a source of your own or stop insisting on contradicting the science to make things scarier.

Now That's A Fantastic Video Game Ad

BicycleRepairMan says...

Tried this once, didnt figure out ANYTHING, just stared at some spaceship in empty space while navigating some config menus I didnt understand at all. Ragequitted after half an hour cause nothing happened. But this trailer was pretty awesome.

Boats In Thailand Don't Need Water

brunopuntzjones says...

Go-Devil, mud motor, etc. Not that you are supposed to actually use them like in the video...

But as noted above, direct drive. Output shaft connected directly to the engine. Used a lot in the south for navigating very shallow water.

Nixie: Wearable Camera That Can Fly

My_design says...

From the interwebs:
"Nixie isn’t going to be on this Christmas’ shopping list and is simply a concept at this stage."
and
"The Nixie prototype, as it is now, looks like it could break at a moment’s notice, and resembles more a school science project than the next big wearable."
and
"Nixie is currently in prototype stage and as an idea, was born only ten days before the deadline for the competition. But despite having a lot of work to do, the team's pitch convinced the judges not only that the product is brilliant, but that the team has a viable business plan and can make the product, quite literally, take off. Prize money will be used for improving the propellers, motors and object navigation, as well as miniaturisation of the whole product."

I still think Intel got conned.

What this tells me is that everybody sees potential but that what they showed in the video was pure concept design. They have a very long road ahead of them still. My key issues are and remain:
Getting the booms to bend around the wrist so as to bring the motor pods back together.
Fitting the electronics into a format that will fit onto a wrist.
Maintain an acceptable level of performance for an acceptable level of time.

Funny thing is that they mention all of the things I've commented on:
Propellers, miniaturization, and navigation.

I would add form factor and battery life. But Props will be a key issue as getting efficient props at this size is very difficult and maintain tolerances in production.

These competitions never give out cash prizes for theory, they only pay off for actual working prototypes. Otherwise SpaceX would be a movie, as would Deepflight and whatever they called the solar plane...along with dozens of other technologies that have come from these competitions. They just don't pay off on these competitions unless you can PROVE you solved the problems (known AND unknown) and MADE at least one prototype that works.
Intel is no dummy. They know full well you can use their own product to create a video showing anything you wish, so they would NOT be 'conned' out of $500000 with a video. That's a silly thing to say.
I'll come back and tell you that you seem to be wrong today. :-)

EDIT: Don't get me wrong, you may be right it will take 5 years to make them cheap and durable enough to sell them.

how every debate i have had with a libertarian looks like

VoodooV says...

I can't remember who said it, but I've always liked this quote:

Capitalism is a great engine for innovation, but it's a shitty way to have a just and fair society. (after googling, it seems lots of people have said something to that effect)

Capitalism is great, but it needs to be controlled.

I will disagree though. Voters have the power to make some huge changes The corporate world may have a huge influence over Gov't, but it's dependent on the populace not giving a damn and looking the other way.

There will come a point where people are pushed to a tipping point, then things will happen. Hopefully in a peaceful fashion. One way or another it will happen, because as Hedges already pointed out. Truly unrestricted capitalism will destroy itself.

The oligarchy is trying to create a modernized system of serfdom and perpetual debt. Give people the illusion of freedom, but they're really not. Every major life decision in the modern world usually involves going into significant debt and spending decades digging yourself out.

Want a good education? Gonna have to go into massive debt. Even if you're successful, it will take a long time to get out.

Want to get married? society says you have to have an expensive ring and go into debt for probably 30 years to get a house for your family. And you wonder why more and more people are flipping the bird to the "traditional family unit"

Want a decent car just so you can get around? Even more debt

Hope you never get divorced, because that's still more debt.

Hope you're lucky enough to not have a major accident or illness either. Yep, more debt.

I know a lot of people are able to successfully navigate these things and still come out ahead, but they're quickly becoming the exception, and not the rule. And it's often a question of luck, not of skill or smarts or being chosen of your preferred deity. blind stupid luck. So those that make it have no cause to look down their nose at those who didn't make it.

There is a reason feudalism system got thrown out. It's just been repackaged to fool people. When enough people realize it, it will be thrown off again.

notarobot said:

It's true that free markets have enabled innovation over the past two centuries since the adoption of capitalistish models by most of the world.

The issue I see the interviewer struggling with, and Hedges not really getting across to him, is that the free market run amok has led a perversion of capitalism. This perversion, however you wish to describe it (corpratism?/neo-feutilism?) has created ultra-wealthy elite who are able to impose vast influence over society, like princes and kings before the Storming of the Bastille.

Hedges is warning that revolution will may be the only option left if the present shift in power continues on it's present path unchecked. (I do not see such upheaval as possible at the present time---though I don't dispute that the seeds are there. Revolutions are often preceded by disaster or famine.)

The interviewer seemed more interested in making his own points and arguing with Hedges rather than trying to help Hedges to draw out and refine his main point into a digestible thesis.

Law Student Prevails Over State Robot Thug

chingalera says...

@bremnet-Concealed is only the 'way-to-go (check your state's laws) unless you are able or willing to navigate the laws and duties and fine-print responsibilities once you sign-on to another hoop-toss to jump through. Most US state's existing laws let citizens arm themselves and carry legally without being on another bullshit hit-list.

SO the guys' being a dick, what of it with regard to state-sanctioned fascism, eh?? Get naked at your cousin's wedding and a bit tipsy an' let some bored neighborhood informant with a cell-phone and a tree-stump in their ass call the local pigs, and see how fast your world collides with your bank account and how many do-not-hire lists you get placed on. Preach that shit from a pulpit how about it??
