So here it all is.  It doesn't seem like a lot of people want to post here yet, so tell me what you think and suggest to make it interesting.  I don't want this forum if nobody's interested, so air your opinions

Being a lover of shiny gadgetry, useful tools, and developing technologies, I like the idea of this.

I'm seeing so far its about hashing over of the ramifications of new developments. 
I'll also use it to fill the space between asking tech experts and asking anonymous given half a chance.  (No pulled punches here, but higher incidence of serious advice, and no one trying to sell anything.)

Your creation, so feel free to drop a mission statement of what you think fits / doesn't fit.

Anything you think uses engineering or science to impact society is to be posted here and compared to relevant phenomena/events.  This is for the purpose of better understanding where technology will lead our BIPs, BE's, and other perceptual grid metaphors.

Having used a Nexus 5 with Google Now voice command for the last couple of weeks, I'd say the AI in the video is pretty much what I'm using right now, plus some scripted personality traits. No way I'm shelling out half a grand for a less-mobile mobile device. I'll wait til the end of next year, start of 2017 and pick one up for a hundred or so.

The tracking cam alone would be worth more than that to me if I don't get a quad drone in the meantime. That reminds me - I'm supposed to be building one of those...

I'll probably grab one of those when the tech is a bit more affordable. It's actually impressed me quite a bit and it'll be good to see some of the apps that get developed for it.

I assume everyone's already realised how it can be turned to sexual purposes/services. I'd guess security it's high on the list of development concerns and even if it is, it's probably already compromised. So if you get one it may be advisable to throw a towel or something over it when not in use. Even still, it's probably a godsend to those in long distance relationships.

Thinking further for a moment, given the access the NSA/GCHQ etc has to any device currently, this is essentially sticking a government monitored CCTV camera into your home/bedroom. It's less appealing to me now.

Thinking again, would it not be possible to create some kind of Ipad docking station that does most of this? I'd assume the apps to be relatively compatible and it would probably drop the unit cost substantially.

Apple is probably a bad example due to their approach but I'd guess any other tablet manufacturer would be either keen or working on something similar. I don't actually have or use a tablet so if the above is idiocy, feel free to correct me.

The thought had crossed my mind. Along the same lines as the cardboard VR goggles Google was handing out at IO last month. All you need is something articulated you can stick an android device in and an app to drive it via bluetooth.

The hardware would take 5 minutes to source for anyone with basic electronics skills and knowledge of arduino or raspberry pi platforms and the housing could be knocked up in max and printed at shapeways.

The real kicker is the software platform. Best bet is leverage Watson or Google Voice API and have a look of open source methods of motion tracking, face recognition and the like but, even then, there's a lot of specific shit that's going to have to be hand coded. Nothing massive, tho.

Main problem for me would be the animation. They got an ex Disney guy working on that IIRC

Fellow geeks,

I was going to make a thread elsewhere, but I figured this would be the best way to inform the techmologists, specifically, and possibly bring some traffic to this section of the forum at the same time.

Anyways, I was wanting to create either a Facebook group (Less-likely, unless favored by you all), a forum, or just a thread (Maybe here, if you guys would like) that would be used to discuss all matters on security. Everything from architectural design flaws, to viruses, to cryptology, to cyber-security, to social engineering. I want people to read and contribute if they are interested and willing to do a lot of research. I know I'm currently interested in physical security (The general security of a building or facility, dealing with architecture and social engineering vulnerabilities.) and will be reading for countless hours on the subject. I'll be looking into getting access to public, and possibly confidential, records on government jobs/private jobs - break-ins and invasions of systems by private organizations and government agencies. This would be very informative, depending on how they will limit the information I will request for, and it will probably put me, and anyone else looking at it, on a watch-list of sorts. But, keep in mind, I will be requesting this information officially, and would be informing them of its use. If I have to limit what I can write about, I will. If they won't let me have anything I ask for, so be it. I'll find another way to connect the concepts to application, in that case.

This would be a great help in my research and study of the vast field of security. I want people to write anything from small articles, to extensive essays (This will probably be me). So, if you're more of a light-reader, it could be useful for you. And, at someone's request, anything anyone writes may be able to be summarized by me, or whoever else is a part of the group.

If anyone has any ideas about how this little discussion-group should be done, or if someone would be interested in joining such a group, please let me know here, make this a new thread, or message me.

Thanks   :fnord:

P.S I want to avoid bringing in people from other security forums like HackForums and such because those people tend to be outrageously stupid and/or incredibly bigoted Nazis, etc.

I would start a thread and see if it has legs, unless you mean to bring in an audience from places that aren't here, in which case a small board might be suitable.

Segregating Facebook profiles for security discussions are a bother.

I know of people who aren't from this forum that would love to join and contribute, but I figured I would let my favorite forum get first dibs on membership and format ideas. So, it looks like a board may be the best option.

I wanted this group to be very inclusive, and readily available to anyone who wanted to read on the subject of security. So, if I did use Facebook, I would make it a public group. Facebook, and most of its user-base, don't seem to be accustomed to verbose discussions like this. I feel like most of the people who would join would be turned off by the gross amount of content, and leave the occasional "TL;DR FAGGOT." ~ Not the kind of feedback I want.

I understand that being very inclusive means having to deal with a user-base that is diverse in knowledge, curiosity, drive to learn, and manners. But I would like the board to maintain a certain level of professionalism. This can usually be balanced with methods like moderation of threads and sections of the boards, or thorough and strict board rules. But I also don't want the board to be this strict, production-only machine, that stomps out creativity. Basically, I want to find a balance between professionalism and creativity. But I don't know how to achieve that without a pre-installed user-base that "trolls the trolls into submission" or "pokes at you with sticks until you ooze creativity (or hogwash, depending on whether or not you're a schmuck, through and through)." You know, like this one!  :p

So, I guess I can start it out as a thread on here, and bring my friends here (Hey, more traffic here will benefit all of us... Right?). The problem is, they don't know shit about Eris or apples. And I'm worried that some of you might scare them away with your "ooby dooby magic talk" and poetry potion nonsense. Should I just show them the metaphorical and horror-ridden gates of Discordintismasticism, or whatever, and let them fight their instincts to hurl on their own? I mean, who knows? One of them may come out spewing that "Thick sweet juice (https://www.youtube.com/watch?v=jjtkMCLRf-M (https://www.youtube.com/watch?v=jjtkMCLRf-M))" known as enlightenment.

Engineers fly first-ever plane with no moving parts

As per the article:

"Now MIT engineers have built and flown the first-ever plane with no moving parts. Instead of propellers or turbines, the light aircraft is powered by an "ionic wind"—a silent but mighty flow of ions that is produced aboard the plane, and that generates enough thrust to propel the plane over a sustained, steady flight.

Unlike turbine-powered planes, the aircraft does not depend on fossil fuels to fly. And unlike propeller-driven drones, the new design is completely silent.

"This is the first-ever sustained flight of a plane with no moving parts in the propulsion system," says Steven Barrett, associate professor of aeronautics and astronautics at MIT. "This has potentially opened new and unexplored possibilities for aircraft which are quieter, mechanically simpler, and do not emit combustion emissions."

He expects that in the near-term, such ion wind propulsion systems could be used to fly less noisy drones. Further out, he envisions ion propulsion paired with more conventional combustion systems to create more fuel-efficient, hybrid passenger planes and other large aircraft."

Here's a link: https://techxplore.com/news/2018-11-first-ever-plane.html

This is definitely "thinking outside the box."

I've been following this since before it became a DARPA thing back in 06. There's been four or five people working on it since the mid 90s, they got DARPA backing after they showed a tethered flight prototype (about a foot long wingspan and literally just electric cables wrapped around a shaped piece of plywood) but that went nowhere and got canned around 2010 ish iirc.

Good to see they kept going and got something more useful. Also super interesting that they have reason to think the efficiency scales well now, that was a huge deal with the DARPA project, they couldn't make it scale up at all.

It was brought up in some UFO discussion somewhere, a suggestion for the propulsion of saucer-type UFOs. (They do actually seem like they're possible if done properly with this tech.)

I was curious, googled it, and they had a really crappy website on an .edu domain showing how they got regular extension cables to produce enough ionic wind to visibly glow. It was crazy, but just incomplete enough to annoy me, so I kept googling it every few months to check the progress out.

Around the time they got the DARPA contract, they showed a working tethered prototype and a concept image of a scifi looking stealth bomber using the old, "giant blue glowing coil of doom" method they were working on at the time, but otherwise kinda like the Nighthawk.

I'm not one hundred percent sure if they are the same people as this group, but the main guy on that project was the leader of the field (because no one else was in it, mind) so I'm inclined to assume it's connected.

Unraveling The Nazi Origins Of The American Space Program

I'll post this here, as it is part of the history of Space Techmology.

This article contains an excerpt from the book MOONBOUND: Apollo 11 and the Dream of Spaceflight, by Jonathan Fetter-Vorm. The article is difficult to quote, as it is done in graphic novel format. And, as I'm certain the graphic panels are copyright protected, I'm not going to copy and paste any of them here. Still, the article really is of historical interest.

A Cool New Thermoelectric Generator Has Been Developed

Device generates light from the cold night sky

As per the article:

'An inexpensive thermoelectric device harnesses the cold of space without active heat input, generating electricity that powers an LED at night, researchers report September 12 in the journal Joule.

"Remarkably, the device is able to generate electricity at night, when solar cells don't work," says lead author Aaswath Raman (@aaraman), an assistant professor of materials science and engineering at the University of California, Los Angeles. "Beyond lighting, we believe this could be a broadly enabling approach to power generation suitable for remote locations, and anywhere where power generation at night is needed."'

Here's a link: https://www.eurekalert.org/pub_releases/2019-09/cp-dgl090519.php

This type of generator is interesting at a theoretical level, but I don't see it being very practical.
The researchers currently report 25 mW/m2, and think they can improve to 0.5 W/m2.  In comparison, a solar panel can give you 200 W/m2.

And, as with solar panels, this technology requires a clear sky. If it is overcast, the sky temperature will be higher, and reduce the available temperature difference. This approach requires the ground to be warmer than the sky to work.

True, the power generation is not impressive. But, I do find the technology interesting.

Today, you can get a 25 mW (rated) solar cell that measures under 2 cm2 for $2.57 (in quantity).
500 mW brings that up to ~$10.

Even if you consider that the actual power out of these solar cells is likely to be below the rating, I would say the cold sky thermoelectric approach is optimistically a couple of orders of magnitude behind the point where it would be competitive.

RTG's are only viable because there is a huge temperature difference involved.

DARPA partnered with NASA's Space Technology Mission Directorate on the DRACO project, as both agencies will benefit from this leading edge technology. The in-space flight demonstration of a nuclear thermal rocket engine vehicle will take place no later than 2027."

Faster, Farther, More Agile
Chemical propulsion engines have long been the standard for spaceflight, but for humans to travel to Mars, they will need much more powerful and efficient propulsion. Nuclear thermal propulsion (NTP) engines offer thrust as high as conventional chemical propulsion with two-to-five times higher efficiency, which means the spacecraft can travel faster and farther and can significantly reduce propellant needs. They also enable abort scenarios on journeys to Mars that are not possible with chemical propulsion systems."

I haven't hear much about NTP in recent years. So, it will be interesting to see the rocket engine this R&D project manages to build.

"Old EV Batteries Get a Second Life Storing Solar Energy"

"We're at a point where we really can scale this."

As per the article:

"To make renewable energy from intermittent sources like solar and wind available when it is most needed, it's becoming more common to use batteries to store the power as it's generated and transmit it later. But one thing about the Cuyama facility, which began operations this week, is less common: The batteries sending energy to the grid once powered electric vehicles."

And, further along in the article:

"The facilities are meant to prove the feasibility of giving EV batteries a second life as stationary storage before they are recycled. Doing so could increase the sustainability of the technology's supply chain and reduce the need to mine critical minerals, while providing a cheaper way of building out grid-scale storage.

"This is what's needed at massive scale," said Freeman Hall, CEO of the Los Angeles-based large-scale storage system company."

This sounds like a potential win-win reuse of old tech hardware to me.

"New technology installed beneath Detroit street can charge electric vehicles as they drive"

As per the article:

"Crews have installed what's billed as the nation's first wireless-charging public roadway for electric vehicles beneath a street just west of downtown Detroit.

Copper inductive charging coils allow vehicles equipped with receivers to charge up their batteries while driving, idling or parking above the coils.

The quarter-mile segment of 14th Street will be used to test and perfect the technology ahead of making it available to the public within a few years, according to the Michigan Department of Transportation."

There have to be convenient ways for EV owners who don't have garages, private driveways, or private parking spaces to charge their vehicles. I believe this technology will make owning and driving an EV a lot more practical for most people. It also opens up the possibility of places like drive-thru restaurants, to install wireless-charging. Other businesses with parking lots could benefit as well, as it eliminates the need for their customers to have do deal with charging cables.

"First plasma fired up at world's largest fusion reactor"

"Japan's JT-60SA tokamak will test technologies put to use in ITER"

As per the article:

"The long trek toward practical fusion energy passed a milestone last week when the world's newest and largest fusion reactor fired up. Japan's JT-60SA uses magnetic fields from superconducting coils to contain a blazingly hot cloud of ionized gas, or plasma, within a doughnut-shaped vacuum vessel, in hope of coaxing hydrogen nuclei to fuse and release energy. The four-story-high machine is designed to hold a plasma heated to 200 million degrees Celsius for about 100 seconds, far longer than previous large tokamaks."

And, as per the end of the article:

"By 2050, Japan also hopes to build DEMO, a proposed demonstration power plant that would provide a stepping stone from the research of JT-60SA and ITER to commercial fusion power. Shirai says he is well aware of the competition from alternative approaches to fusion energy, fueled by an influx of private money into the field. But with competition comes opportunities for collaborations among those with new ideas. "Having many people coming into this area is a very good thing," Shirai says." 

Developing fusion power has been a long slog. But, it appears that some progress is being made.

"Novel snake-like robot 3D prints its own body to grow longer"

As per this article:

"A trio of soft robotics researchers at Fondazione Istituto Italiano di Tecnologia, in Italy, working with a colleague from the University of Montpellier, in France, has developed a unique type of robot that 3D prints its own body as a means to grow longer. In their paper published in the journal Science Robotics, the group describes how they created their robot and the possible uses for it.

As science and technology continue to mature, scientists find novel ways to combine innovations into new types of technology. In this new effort, the research team combined robotics with 3D printing, resulting in the creation of a new kind of robot that can grow longer at will.

The robot is shaped like a snake and has a head that spins. As the head spins, it creates more body mass behind it using 3D printing, resulting in elongation of the robot. The robot can also be programmed to grow in desired ways, such as toward light, or against gravity. This gives the robot the ability to grow in a vine-like manner. The team has named their robot FiloBot."

Swell. It's only a matter of time before someone intentionally programs a robot to reproduce at will.

We have the techmology.

"Poopspotting: How AI and satellites can detect illegal manure spreading in Wisconsin"

As per this article:

"After a fresh February snow, a satellite about the size of a shoebox, busy snapping photographs as it circuited the planet at 17,000 miles per hour, captured something dark in Wisconsin.

About 56 tons of livestock bedding and manure had been spread atop Mark Zinke's frozen alfalfa field.

The image, beamed down to the surface, eventually appeared on the computers of Stanford University researchers, who relayed it to the offices of the Wisconsin Department of Natural Resources.

A staff member looked it over. He decided it was noteworthy and passed along the information to another employee in a nearby city.

Zinke, a Brownsville dairy farmer who cares for a herd of more than 1,300 cows, had forgotten about the whole thing until he later heard from the agency."

So, that's what all of those billions of dollars spent on the Space Race, and AI Development was all about! Now we have the techmology to see illegally dumped manure from outer space, clearly identify it, and report it to a meat-based intelligence unit (MBIU) who then reports it to the local authorized manure police department (MPD).

I wonder how long it will be before the MBIU, an obvious weak link, is replaced by AI.
