Arbtr wants to create an anti-feed where users can only share one thing at a time

At a time when the models of traditional social networks are being questioned, it’s more important than ever to experiment with alternatives. Arbtr is a proposed social network that limits users to sharing a single thing at any given time, encouraging “ruthless self-editing” and avoiding “nasty things” like endless feeds filled with trivial garbage.

It’s seeking funds on Kickstarter and could use a buck or two. I plan to.

Now, I know what you’re thinking. “Why would I give money to maybe join a social network eventually that might not have any of my friends on it on it? That is, if it ever even exists?” Great question.

The answer is: how else do you think we’re going to replace Facebook? Someone with a smart, different idea has to come along and we have to support them. If we won’t spare the cost of a cup of coffee for a purpose like that, then we deserve the social networks we’ve got. (And if I’m honest, I’ve had very similar ideas over the last few years and I’m eager to see how they might play out in reality.)

The fundamental feature is, of course, the single-sharing thing. You can only show off one item at a time, and when you post a new one, the old one (and any discussion, likes, etc) will be deleted. There will be options to keep logs of these things, and maybe premium features to access them (or perhaps metrics), but the basic proposal is, I think, quite sound — at the very least, worth trying.

Some design ideas for the app. I like the text one but it does need thumbnails.

If you’re sharing less, as Arbtr insists you will, then presumably you’ll put more love behind those things you do share. Wouldn’t that be nice?

We’re in this mess because we bought wholesale the idea that the more you share, the more connected you are. Now that we’ve found that isn’t the case – and in fact we were in effect being fattened for a perpetual slaughter — I don’t see why we shouldn’t try something else.

Will it be Arbtr? I don’t know. Probably not, but we’ve got a lot to gain by giving ideas like this a shot.

Does Ready Player One reveal the future of VR?

It was barely minutes after the Ready Player One premiere, and texts from my friends and colleagues in the VR community began pouring in…

“How was it?”

Those of us in the mixed reality industries have been waiting for this film like the VR messiah that will deliver us to public mass adoption. And the breathless prayer? “Please, oh please, let Ready Player One make VR look cool.”

To many, VR creators make expensive content that few will ever experience or have interest in experiencing. I have read dozens of articles in the last year announcing either the end or the beginning of VR.

I have seen VR portrayed as a portent for humanity’s most solitary, basic, and evil instincts over and over again in television and film. Most of all, I received questions from people that are confused by what this technology is and moreover, why it even has value.

Because of Ready Player One, there are now giant billboards on streets around the world where someone is wearing a VR Headset. For those of us who have lived and breathed this technology for years, this movie is everything.

And so, I was excited to find that yes, this movie portrays something that I’ve known and felt in my bones for a while now — VR is in fact cool.

I’m imagining that people will now want to suit up, run to THE VOID or the Imax Experience Center and try VR for themselves. But here’s a word of caution to the uninitiated: VR is currently not the OASIS. Please do not expect VR to feel, look and behave like the OASIS, because we are not there yet. But I’ll be damned if we’re not close.

So given this, here’s an overview of what’s present in the film, where we are today, and what the future might hold.

NOTE: Some minor film spoilers below.

Headsets

Film:

At first glance, the headsets in Ready Player One look surprisingly like generation one Oculus Rifts in size and shape. However, the film claims that Head-Mounted Displays (HMDs) projection in 2024 is composed of harmless lasers beaming directly into your retinas– far from our current display-based HMDs. The film’s headsets appear to be inside-out tracking, lightweight, wireless, and can produce images indistinguishable from reality with minimal or no processing lag. Other sci-fi-based headsets appear later in the film, when Wade upgrades his HMD to a model with semi-transparent glass. In the book, there are allusions to OASIS’ massive servers in Columbus, so all the processing power is probably not coming from the headsets themselves but rather sent via 5G (or higher) network to each user.

Today:

Off-the-shelf HMDs are tethered to powerful PCs, and those coming later in 2018 (Vive Pro , Oculus Go, and supposedly Oculus Prototype Santa Cruz, among others) are either a mobile-based power/resolution or require a PC wireless display link. While we don’t have lasers entering our retinas (yet), we can assume someone’s working on it.

Tomorrow:

When it is released, Magic Leap promises to be the closest thing we have to a complex mixed reality headset. It beams information directly into your eyes that utilize your sense of depth, which should make for a more comfortable experience than hours in a headset staring at pixels; yet, it’s imperfect as the field of view will in no way be full resolution like in the OASIS. Right now the design is somewhat clunky– there’s still a walkman-like battery pack to deal with and a FOV of 40 degrees at best. Other than the release of Ready Player One, the launch of Magic Leap One is probably the most anticipated event in the brief history of VR. As a side note, the term “VR” may no longer be applicable, because it’s predicted that AR and VR headsets will merge and become one device.

Haptics

Film: 

The haptic suits in RPO are aesthetically gorgeous. As described in the original book, an interwebbing of sensors and material covers the user’s body — it looks like a slim-fit wetsuit but with gloves and boots. When characters get shot or hit in VR, they feel the pain on their bodies, which thematically ups the stakes during the battle scenes. There’re also a few instances of “pleasure” haptics.

In the VR nightclub, Art3mis dances against Wade and the crotch region of his suit, ahem, “activates.” Other scenes contain a few cheeky allusions to some risque things people might be be up to in the OASIS.

Our villain Nolan Sorrento wears a haptic suit on his bouts in the OASIS, but usually confines the haptic experience to an ornate leather chair that allows him to feel sensations/maintain a patriarchal technical overlord vibe. (Cool.)

Today:

Sorrento’s chair feels reminiscent of the Positron rig that has been dotting film festivals and hotels lately. They’re quite comfy and are great for first time VR users. In terms of romantic haptics, the teledildonics and VR porn industry is alive and well, and new products keep being developed. Haptic gloves like Haptx VR Gloves do exist and keep getting better! So far, texture, shape, and cold/warm sensations are all achievable by individual systems and products.

Tomorrow:

Complete sensory VR immersion is years away, but is one of the most oft requested and dreamed about advances in the industry. Teslasuit appears to be the next product to market that aims to let you feel it all in VR, and it looks a hell of a lot like Wade’s suit.

Movement

Film:

One of the first scenes in the film features Wade navigating the OASIS on a simple omnidirectional treadmill. As the film progresses, movement mechanics get into completely new territory. The “sixers” (the film’s enemy army against the Gunters) stand upright in individual pods with treadmills beneath them; if needed, they and can sit down to “drive” vehicles. On the Gunter side, in Aech’s truck the “Hive Five” are tethered to the ceiling via cables for unobstructed fighting moves.

Today:

Omnidirectional treadmills exist today but the kinks are being ironed out. Many are designed similar to ones in the film (micro- and macro-treadmill arrangements). User motion tracking is done via external sensors, and for maximum movement the closest thing we have to a tetherless VR experience is location-based experiences a la The Void, and that still requires backpacks.

Tomorrow:

A Virtual Reality where your physical movements match virtually in a 1:1 ratio without the need for wires. Inertial Measurement Units (IMUs) are already in use for motion capture in films and games, and these systems can be integrated into next-next-gen haptic suits for full-body presence. (That being considered, some folks will always want to play from a couch or chair.)

Digital currency

Film:

One universal currency exists in the OASIS, and its value is more stable than real-world currency. (Is FIAT even real currency some might ask? Don’t start with me, man). In the OASIS, currency is more trusted than in the actual world. Wade receives bonuses for leveling up in the race to catch the egg, and uses digital currency to order real products via drones in the real world. In the OASIS, users can go on quests that require work that are actual proof-of work.

Today:

So cryptocurrency today is a bit of a mess. Between ICO’s failing to launch or completely made up advisory boards, people are doubting the security of a digital currency. That being said, millions of people are eager to learn more about this currency revolution and its claims to strive for the financial equalization of the world.

Tomorrow:

Democratizing cryptocurrency is paramount. Some companies, like Robin Hood, are doing a great job by providing cryptocurrency to the masses via readily accessible mobile apps. Some argue that Ready Player One actually predicted the rise of cryptocurrency; however, it did not predict alt-coins such as Ethereum, Monero or Ripple.

Avatars

Film:

As Wade declares in the beginning of the film, in the OASIS you can “be whomever you want to be”, whatever appearance, ethnicity, background, gender, sex, or species. It’s all up to you as a consumer and denizen of the OASIS. For example, Wade dawns a haircut which is then corrected by Art3mis to be cooler (more spikey). Wade’s best friend Aech is an African American female but is able to be a male muscled warlord in the OASIS. There’s a glorious beauty to avatars in this film for the free folk that is contrasted by the monochromatic Sixers in their Loyalty Centers. This is a free and open internet — be who you want to be.

Today:

It would be lovely if who we are in VR is a direct representation of our real selves — however current methods for duplication leave out facets of what makes us human. For example, Facebook wouldn’t let this VR user be fat. Scanning technologies such as Windows Mixed Reality capture stages can scan your likeness — but it will cost a pretty penny.

Tomorrow:

In the future, avatar creation will be a democratized process where users can scan themselves (either face or body) to import into the cloud, or simply be whatever figure suits their preference. Think of this as a VR Chat-level of character selection but with customization to the nines.

We are at the cusp of a media revolution: New definitions of reality develop every day, and Ready Player One is giving these technologies mass market exposure.

At the same time, this film speaks to the morality surrounding how we equip ourselves with immersive tech in the new digital frontier. Will the OASIS be well protected and well propagated? Should we look to artists or business people to be the curators of this space?

If we are to avoid the advertisement-laden virtual realm that RPO’s 101 Industries desires, we must take steps in this early adoption phase. That is the core of the film’s premise: virtual reality has as much impact on the world as real reality. Choose wisely.

Knitting machines power up with computer-generated patterns for 3D shapes

At last, a use for that industrial knitting machine you bought at a yard sale! Carnegie Mellon researchers have created a method that generates knitting patterns for arbitrary 3D shapes, opening the possibility of “on-demand knitting.” Think 3D printing, but softer.

The idea is actually quite compelling for those of us who are picky about their knitwear. How often have we picked up a knit cap, glove, or scarf only to find it too long, too short, too tight, too loose, etc?

If you fed your sartorial requirements (a 3D mesh) into this system from James McCann and students at CMU’s Textiles Lab, it could quickly spit out a pattern that a knitting machine could follow easily yet is perfectly suited for your purposes.

This has to be done carefully — the machines aren’t the same as human knitters, obviously, and a poorly configured pattern might lead to yarn breaking or jamming the machine. But it’s a lot better than having to build that pattern purl by purl.

With a little more work, “Knitting machines could become as easy to use as 3D printers,” McCann said in a CMU news release.

Of course, it’s unlikely you’ll have one of your own. But maker spaces and designer ateliers (I believe that’s the term) will be more likely to if it’s this easy to create new and perfectly sized garments with them.

McCann and his team will be presenting their research at SIGGRAPH this summer.

Who gains from Facebook’s missteps?

When Facebook loses, who wins?

That’s a question for startups that may be worth contemplating following Facebook’s recent stock price haircut. The company’s valuation has fallen by around $60 billion since the Cambridge Analytica scandal surfaced earlier this month and the #DeleteFacebook campaign gained momentum.

That’s a steep drop, equal to about 12 percent of the company’s market valuation, and it’s a decline Facebook appears to be suffering alone. As its shares fell over the past couple of weeks, stocks of other large-cap tech and online media companies have been much flatter.

So where did the money go? It’s probably a matter of perspective. For a Facebook shareholder, that valuation is simply gone. And until executives’ apologies resonate and users’ desire to click and scroll overcomes their privacy fears, that’s how it is.

An alternate view is that the valuation didn’t exactly disappear. Investors may still believe the broad social media space is just as valuable as it was a couple of weeks ago. It’s just that less of that pie should be the exclusive domain of Facebook.

If one takes that second notion, then the possibilities for who could benefit from Facebook’s travails start to get interesting. Of course, there are public market companies, like Snap or Twitter, that might pick up traffic if the #DeleteFacebook movement gains momentum without spreading to other big brands. But it’s in the private markets where we see the highest number of potential beneficiaries of Facebook’s problems.

In an effort to come up with some names, we searched through Crunchbase for companies in social media and related areas. The resulting list includes companies that have raised good-sized rounds in the past couple of years and could conceivably see gains if people cut back on using Facebook or owning its stock.

Of course, people use Facebook for different things (posting photos, getting news, chatting with friends and so on), so we lay out a few categories of potential beneficiaries of a Facebook backlash.

Messaging

Facebook has a significant messaging presence, but it hasn’t been declared the winner. Alternatives like Snap, LINE, WeChat and plain old text messages are also massively popular.

That said, what’s bad for Messenger and Facebook-owned WhatsApp is probably good for competitors. And if more people want to do less of their messaging on Facebook, it helps that there are a number of private companies ready to take its place.

Crunchbase identified six well-funded messaging apps that could fit the bill (see list). Collectively, they’ve raised well over $2 billion — if one includes the $850 million initial coin offering by Telegram.

Increasingly, these private messaging startups are focused on privacy and security, including Wickr, the encrypted messaging tool that has raised more than $70 million, and Silent Circle, another encrypted communications provider that has raised $130 million.

Popular places to browse on a screen

People who cut back on Facebook may still want to spend hours a day staring at posts on a screen. So it’s likely they’ll start staring at something else that’s content-rich, easy-to-navigate and somewhat addictive.

Luckily, there are plenty of venture-backed companies that fit that description. Many of these are quite mature at this point, including Pinterest for image collections, Reddit for post and comment threads and Quora for Q&A (see list).

Granted, these will not replace the posts keeping you up to date on the life events of family and friends. But they could be a substitute for news feeds, meme shares and other non-personal posts.

Niche content

A decline in Facebook usage could translate into a rise in traffic for a host of niche content and discussion platforms focused on sports, celebrities, social issues and other subjects.

Crunchbase News identified at least a half-dozen that have raised funding in recent quarters, which is just a sampling of the total universe. Selected startups run the gamut from The Players’ Tribune, which features first-hand accounts for top athletes, to Medium, which seeks out articles that resonate with a wide audience.

Niche sites also provide a more customized forum for celebrities, pundits and subject-matter experts to engage directly with fans and followers.

Community and engagement

People with common interests don’t have to share them on Facebook. There are other places that can offer more tailored content and social engagement.

In recent years, we’ve seen an increase in community and activity-focused social apps gain traction. Perhaps the most prominent is Nextdoor, which connects neighbors for everything from garage sales to crime reports. We’re also seeing some upstarts focused on creating social networks for interest groups. These include Mighty Networks and Amino Apps.

Though some might call it a stretch, we also added to the list WeWork, recent acquirer of Meetup, and The Guild, two companies building social networks in the physical world. These companies are encouraging people to come out and socially network with other people (even if just means sitting in a room with other people staring at a screen).

Watch where the money goes

Facebook’s latest imbroglio is still too recent to expect a visible impact in the startup funding arena. But it will be interesting to watch in the coming months whether potential rivals in the above categories raise a lot more cash and attract more users.

If there’s demand, there’s certainly no shortage of supply on the investor front. The IPO window is wide open, and venture investors are sitting on record piles of dry powder. It hasn’t escaped notice, either, that social media offerings, like Facebook, LinkedIn and Snap, have generated the biggest exit total of any VC-funded sector.

Moreover, those who’ve argued that it’s too late for newcomers have a history of being proven wrong. After all, that’s what people were saying about would-be competitors to MySpace in 2005, not long before Facebook made it big.

Red Hat looks beyond Linux

The Red Hat Linux distribution is turning 25 years old this week. What started as one of the earliest Linux distributions is now the most successful open-source company, and its success was a catalyst for others to follow its model. Today’s open-source world is very different from those heady days in the mid-1990s when Linux looked to be challenging Microsoft’s dominance on the desktop, but Red Hat is still going strong.

To put all of this into perspective, I sat down with the company’s current CEO (and former Delta Air Lines COO) Jim Whitehurst to talk about the past, present and future of the company, and open-source software in general. Whitehurst took the Red Hat CEO position 10 years ago, so while he wasn’t there in the earliest days, he definitely witnessed the evolution of open source in the enterprise, which is now more widespread than every.

“Ten years ago, open source at the time was really focused on offering viable alternatives to traditional software,” he told me. “We were selling layers of technology to replace existing technology. […] At the time, it was open source showing that we can build open-source tech at lower cost. The value proposition was that it was cheaper.”

At the time, he argues, the market was about replacing Windows with Linux or IBM’s WebSphere with JBoss. And that defined Red Hat’s role in the ecosystem, too, which was less about technological information than about packaging. “For Red Hat, we started off taking these open-source projects and making them usable for traditional enterprises,” said Whitehurst.

About five or six ago, something changed, though. Large corporations, including Google and Facebook, started open sourcing their own projects because they didn’t look at some of the infrastructure technologies they opened up as competitive advantages. Instead, having them out in the open allowed them to profit from the ecosystems that formed around that. “The biggest part is it’s not just Google and Facebook finding religion,” said Whitehurst. “The social tech around open source made it easy to make projects happen. Companies got credit for that.”

He also noted that developers now look at their open-source contributions as part of their resumé. With an increasingly mobile workforce that regularly moves between jobs, companies that want to compete for talent are almost forced to open source at least some of the technologies that don’t give them a competitive advantage.

As the open-source ecosystem evolved, so did Red Hat. As enterprises started to understand the value of open source (and stopped being afraid of it), Red Hat shifted from simply talking to potential customers about savings to how open source can help them drive innovation. “We’ve gone from being commeditizers to being innovators. The tech we are driving is now driving net new innovation,” explained Whitehurst. “We are now not going in to talk about saving money but to help drive innovation inside a company.”

Over the last few years, that included making acquisitions to help drive this innovation. In 2015, Red Hat bought IT automation service Ansible, for example, and last month, the company closed its acquisition of CoreOS, one of the larger independent players in the Kubernetes container ecosystem — all while staying true to its open-source root.

There is only so much innovation you can do around a Linux distribution, though, and as a public company, Red Hat also had to look beyond that core business and build on it to better serve its customers. In part, that’s what drove the company to launch services like OpenShift, for example, a container platform that sits on top of Red Hat Enterprise Linux and — not unlike the original Linux distribution — integrates technologies like Docker and Kubernetes and makes them more easily usable inside an enterprise.

The reason for that? “I believe that containers will be the primary way that applications will be built, deployed and managed,” he told me, and argued that his company, especially after the CoreOS acquisition, is now a leader in both containers and Kubernetes. “When you think about the importance of containers to the future of IT, it’s a clear value for us and for our customers.”

The other major open-source project Red Hat is betting on is OpenStack . That may come as a bit of a surprise, given that popular opinion in the last year or so has shifted against the massive project that wants to give enterprises an open source on-premise alternative to AWS and other cloud providers. “There was a sense among big enterprise tech companies that OpenStack was going to be their savior from Amazon,” Whitehurst said. “But even OpenStack, flawlessly executed, put you where Amazon was five years ago. If you’re Cisco or HP or any of those big OEMs, you’ll say that OpenStack was a disappointment. But from our view as a software company, we are seeing good traction.”

Because OpenStack is especially popular among telcos, Whitehurst believes it will play a major role in the shift to 5G. “When we are talking to telcos, […] we are very confident that OpenStack will be the platform for 5G rollouts.”

With OpenShift and OpenStack, Red Hat believes that it has covered both the future of application development and the infrastructure on which those applications will run. Looking a bit further ahead, though, Whitehurst also noted that the company is starting to look at how it can use artificial intelligence and machine learning to make its own products smarter and more secure, but also at how it can use its technologies to enable edge computing. “Now that large enterprises are also contributing to open source, we have a virtually unlimited amount of material to bring our knowledge to,” he said.
