DIY Doorbell Will Send Pictures Of Your Guests To Your iPhone

rvRMhPEgIsBdxSYZ

Say you’re a misanthrope and you’re afraid of humans. What to do? Well, you could cower in the dark when people ring your doorbell or you could laugh derisively at their smug faces in the screen of your iPhone. I’m going for the derisive laughter.

This DIY Arduino project involves a simple circuit, a webcam, and a few API calls to PushingBox to enable a truly enjoyable derisive experience.

The system works by pushing images grabbed by the webcam through PushingBox to an app like Prowl or Pushme.to. When the doorbell is pressed, it sends a serial signal to the Arduino board which in turn notifies the various services. The webcam picture then gets sent over to you so you can decide whether to let whoever is outside in.

It’s probably a little more complex than it needs to be, but if you’re totally into watching the world pass you by it’s a great solution and a fun weekend project.

Mind-operated robot arm helps paralyzed woman have her cup o’ joe (video)

braingate2-mind-controlled-robot-arm

Researchers at the Braingate2 consortium have made a breakthrough that allows people with spinal cord or stroke injuries to control robotic limbs with their minds. The original project allowed subjects with motor cortex-implanted chips to move cursors on a screen with their minds, but they can now command DEKA and DLR mechanical arms to grasp foam balls and sip coffee. Researchers noted that dropped objects and missed drinks were frequent, but improved brain sensors and more practice by subjects should help. To see the power of the mind move perhaps not mountains, but good ol’ java, jump to the video below.

Samsung mass-produces 4-gigabit LPDDR2 memory, aims to make 2GB a common sight in smartphones

Image

Samsung started making 2GB low-power mobile memory last year, but as the 1GB-equipped phone you likely have in your hand shows, the chips weren’t built on a wide-enough scale to get much use. The Korean company is hoping to fix that now that it’s mass-producing 20-nanometer, 4-gigabit LPDDR2 RAM. Going to a smaller process than the 30-nanometer chips of old will not just slim the memory down by a fifth, helping your smartphone stay skinny: it should help 2GB of RAM become the “mainstream product” by the end of 2013, if Samsung gets its way. New chips should run at 1,066Mbps without chewing up any more power than the earlier parts, too, so there’s no penalty for using the denser parts. It’s hard to say whether or not the 20nm design is what’s leading to the 2GB of RAM in the Japanese Galaxy S III; we just know that the upgraded NTT DoCoMo phone is now just the start of a rapidly approaching trend for smartphones and tablets.

Microsoft encourages students to buy a PC, gives them a free Xbox 360 in return

Microsoft encourages students to buy a PC, gives them a free Xbox 360 in return

Students. PCs. Free Xbox 360. The Redmond team’s at it yet again. Similar to last year’s deal, Microsoft’s hooking students up with a 4GB Xbox 360 if they drop some cash on one of its Windows machines. It’s simple: shell out over $699 on a PC, or $599 if you’re in Canada, and you’ll be walking out with a shiny new console free of charge — naturally, you’ll have to do so at participating shops such as Best Buy, Fry’s, Newegg, Staples, The Source and, of course, Microsoft’s own stores. The promo is set to kick off here in the States on May 20th, while those living in the True North can take advantage of it starting today. And before you ask — yes, you will need to show your scholar credentials to get in on the bargain.

How Many Daily Downloads Does It Take To Reach The Top Of The App Store? [Updated]

app_store_rankings

It’s hard to underestimate how important ranking in Apple’s top 25 in the iTunes store is for mobile app developers. After all, the top 25 is probably the single most important app discovery mechanism for most iOS users. But how many downloads does it take to rank in the top 25? Mobile app store analytics firm Distimo today published some interesting data that answers just this question. Turns out, in the U.S. store, the answer currently is about 38,400 daily downloads for free iPhone apps and 3,530 for paid iPhone apps. To rank in the top 25 per category, of course, takes significantly fewer downloads, with games unsurprisingly being the most competitive category. It takes 25,300 daily downloads to rank in the gaming top 25 for free apps and 2,280 downloads for paid apps.

For free apps, other competitive categories include ‘entertainment’ (6,700 daily downloads), ‘social networking’ (5,800), ‘lifestyle’ (3,900) and ‘music’ (3,900). Interestingly, in the paid app charts photography apps rank just behind games and entertainment apps. Still, it currently only takes about 270 daily downloads to rank in the photography top 25 for paid apps.

These numbers, of course, are always changing and this just represent a snapshot of what Distimo found when it compiled this data last month.

Update: We just talked to one source with a lot of experience in building mobile apps and who also currently runs a top App Store app. According to this source, Distimo’s numbers are too low and may just represent data from a relatively small number of apps. Keep that in mind as you read Distimo’s data.

Given the popularity of games on iOS, Distimo also took a closer look at the various gaming subcategories. Here, arcade and action games lead the pack:

This is the first time Distimo is releasing a detailed set of these numbers. It’s worth noting, though, that at the end of 2011, the company reported that it still took about 45,000 daily downloads to rank in the top 25 of most popular free apps. Since then, though, Apple has been working hard to shut down various scams and bots that automatically downloaded apps and allowed developers to rank in Apple’s charts without having a real user base (then, once you are in the top 25, of course, real users will automatically find you, of course). Judging from Distimo’s latest data, these efforts are starting to pay off and will hopefully make life a little bit easier for legit developers.

Verizon To Kill All Unlimited Data Plans


afabbro writes “Verizon mentioned in an investor conference that it will be eliminating unlimited data plans, even for those it grandfathered in. From the article: ‘Speaking at the J.P Morgan Technology Media and Telecom conference today, Verizon Communications CFO Fran Shammo told investors that the company’s 3G unlimited data plans that customers were allowed to hang onto last year when Verizon switched to a tiered offering will soon go away entirely. Instead, the company will migrate its existing and new 4G LTE customers to a new “data share plan.”

The company has yet to announce the details of this new plan, but it has said previously that the data share plan will be introduced in midsummer. The plan will allow people on the same family plan to share buckets of data each month, much like they share voice minutes and text messaging. It will also allow individuals to share data across different 4G LTE devices. ‘”

RunCore InVincible SSD wipes data away with the click of a button

Image

This one goes out to all the Bonds in the world. RunCore, a Chinese company specializing in the production of solid state drives, has cooked up a SATA II solution that should satisfy even the most guarded of privacy fanatics. Living up to its grandiose InVincible moniker, this aptly-named SSD’s built to endure extreme temperatures ranging from -45 to 95 degrees Celsius (or -49 to 203 degrees Fahrenheit), read / write data at speeds up to 240Mbps / 140Mbps and protect your 1s and 0s from prying, less-than-reputable eyes. How so? Well, the drive’s actual pièce de espionnite aiguë (that’s fancy for paranoiac fail safe) incorporates a dual-button scheme for clearing away data. Users, much like Neo in ye ‘ole Matrix, will have two colored choices to make: select the green button for “intelligent elimination” (aka overwriting of data) or opt for the “less subtle method” offered by the red button which applies a current to the NAND flash memory for actual physical destruction of your data. So, whether you’re a high-ranking government official, a spy unlike us or just someone who can’t help but look over his / her shoulder, rest assured your secrets can now be safely disposed of. Jump past the break to check out the outfit’s informational video and its woefully out of sync audio track.

Here’s What Could Kill Facebook

What Could Kill Facebook

Facebook is nearing a billion users, but what could topple the big blue giant? Government intervention, the shift to mobile, and a loss of “cool” all have the power to violently disrupt the social network, or at least cause it to lose its strong grip on the market.

Here’s a look at the four things that could ruin Mark Zuckerberg’s dream of a single site that connects the world.

The thread that runs between all these pitfalls is their potential to make Facebook irrelevant. If you can’t access it, its overrun by ads, there’s something better, or it’s simply uncool, Facebook could fade away.

It’s size, network effect, and wise leadership could protect it from these threats, and honestly, I think Facebook has the potential to be successful for a long, long time. But if you had to bet against Facebook, here’s what you’d be betting on.

Big Brother

Facebook is banned in China and access is or has been restricted in several countries including Iran, North Korea, and Syria. Right now this is limiting the social network’s growth potential. But if disputes with governments over what content is appropriate cause it to be shut out of more countries, these roadblocks could divert users to other local social networks. That would fracture the value that comes with having such a high percentage of Internet users in one place. For example, Singapore is a valuable market with a strict government that could drop the ban hammer on Facebook.

Regulation around privacy could also slow Facebook down and make it more vulnerable to competition. Facebook narrowly escaped privacy audits from the U.S. Federal Trade Commission and the European Union. If the government of a core market put restrictions on how Facebook can launch new products or what features it can show where, it could create opportunities for startups to eat Facebook’s lunch. Imagine how much bigger a threat Foursquare would be if Facebook had been restricted from launching its Places location service.

Competition From The Next Mark Zuckerberg

Facebook doesn’t actually need to worry much about Twitter, Google+, or international players. They’ve failed to offer something revolutionary enough to make early adopters ditch Facebook, or mainstream enough to appeal to everyone. What big blue needs to worry about is the next social product visionary, the next Mark Zuckerberg that could turn Facebook into the next Myspace.

While acquiring and acq-hiring top talent from companies like Instagram was easy when it had pre-IPO stock to throw around, recruiting that next Zuck to side with Facebook rather than wage war against it is about to get tougher. Same goes for keeping its current rock stars from leaving to start a true competitor.

It might take a big hardware change like eyewear computers, holograms, or apps you download straight to your brain to finally make Facebook obsolete. Even then that upstart would have quite the uphill battle, but so did Facebook when it launched.

Smaller Screens, Small Ad Revenue

Staying afloat on display ads won’t cut it if the social network wants to live up to or surpass its ~$100 billion valuation, as Chris Dixon writes. It will have to think bigger. But for now, it has to worry about mobile.

Handheld devices have less room for ads and Facebook’s long list of features. Currently, Facebook only shows a few mobile news feed ads per user per day, while it shows as many as four to seven ads per page on the web. But if Facebook chokes mobile with too many ads, usage could plummet. As more users shift the time they spend on Facebook from the web to mobile, it will make less of the money that keeps the lights on for the whole service.

To counteract this, Facebook is aggressively acquiring and hiring from mobile companies like Instagram in hopes of getting its mobile site and apps up to draw more eyeballs. However, while it has a huge footprint of over 500 million mobile users, there’s widespread discontent with the speed of its mobile apps. Many people think they’re cluttered, and complain of slow loading speeds.

Mobile is the biggest threat to Facebook, and the company admits it. If it can’t make more compelling mobile apps and earn more money from these small screens, the shift to mobile will see Facebook lowered into its own grave.

Losing Its Cool

Facebook doesn’t want to be cool. It wants to be a utility. It wants to be the cell phone or the television, not Virgin Mobile or HBO. But the fact is that a big reason Facebook is so popular is because it started by being accessible to only the most envied demographic in the world: Ivy League college students like those at Harvard. It used that prestige to spread like wildfire on every American college campus, and the sexiness of young adulthood to capture the teenage market. Its popularity in the trendsetting United States soon pulled in the rest of the world.

But now your mom is on Facebook. You grandma, professor, little cousins, and plumber are too. It’s not exclusive anymore. Usefulness is what keeps it afloat, but cold, dry, utility for everyone is vulnerable. And soon Zuckerberg will be 30, and he might no longer be seen as the geeky boy genius challenging the adults. He’ll be one of those adults. There are already signs that apathy and distrust for Facebook are setting in.

The slick destroyer of today’s social network would be something that starts elite but that gradually opens up like Facebook did. It would be designed specifically for the hip and young in-crowd. It would recruit big celebrities and carve out an influential niche from which to grow its power. This could be what makes Facebook seem old and boring. And the average Facebook user doesn’t want to go somewhere boring every day. That’s what their jobs are for.

Ultra-Targeted Advertising: Man Uses Pandora For Marriage Proposal

pandora proposal

When I was younger, my parents liked to listen to the big soft rock stations in Los Angeles. Once in a while, the sappy love songs would be interrupted by an emotional dedication from a boy/girlfriend to their significant other. It was awkward, but also kind of beautiful. But mostly awkward.

Now it sounds like Pandora has made an impressive gesture toward keeping that tradition alive, while also demonstrating the power of its ad targeting.

So yeah, this happened: Someone, specifically someone named Kyle Taylor, used a Pandora ad to propose marriage to his girlfriend of almost six years. You can read the full account in his blog post, but the Pandora-relevant bit begins after Taylor has decided that this is a great idea, and has sent off a customer support request:

I started to work with the team at Pandora and they told me this has never been done before, so they would be more than happy to help… that’s when I knew this was going to be it. After working with the creative and technical teams to figure out the best medium, getting passed to their audio advertising team to get a script together and recorded by an awesome voice actress, and once it was finalized it went back to ad trafficking to test out my ad and see if it worked. Of course, it worked out perfectly. (Throughout this whole process, I had to lock down my email account and step out for “unexpected” phone calls a lot – luckily I’m a planning ninja.)

That’s the set-up. As for popping the question itself, Taylor decided to do it on the night of his graduation dinner from University of North Texas. It was carefully planned — he picked a restaurant whose driving distance would create the perfect timing for the ad. So he turned on Pandora (which was built in to his girlfriend’s Hyundai Veloster), and as he pulled onto a service road, the marriage proposal started to play.

Now, you might be thinking that while this is pretty damn impressive, it was incredibly awkward for anyone else listening. In fact, CTO Tom Conrad says that’s “very, very unlikely” that anyone else heard the ad, thanks to the targeting that’s powering Pandora’s efforts to steal local advertisers from terrestrial radio. In this case, the ad was targeted at “very old listeners” in a “sparsely populated zip code,” Conrad says. So Taylor entered some fake demographic information to put himself, and no one else, in the target. The result? He used Pandora’s advertising to deliver a genuinely personal message.

Oh, and by the way: She said yes.
