Using Microfinance to Develop Coding Talent (Video) 23

Posted by Roblimo
from the by-their-bootstraps dept.
Here's a quote from the CodersTrust website: 'CodersTrust is the brainchild of Ferdinand Kjærulff. As a Captain of the Danish army he served as recovery officer in Iraq after the fall of Saddam. He pioneered a recovery project with the allied forces, bringing internet and e-learning to the citizens of the region in which he was stationed. The project was a massive success and inspired him to eventually create CodersTrust – supported by Danida – with a vision to democratize access to education via the internet on a global scale.' A lofty vision, indeed. But with help from the original microfinance company, Grameen Bank, and the Danish International Development Agency (Danida), it seems to be coming true.

Watch Videos in Synch with Fellow iOS Users (Video) 71

Posted by Roblimo
from the let's-all-sing-together-now dept.
This video is about Dr. Saeed Darvish-Kazem and Dr. Michael Pazaratz, two MDs from Canada, who came up with a free iOS app called WeMesh that lets you share video content with iOS-owning friends in real time. You see the video and so does your friend. more or less simultaneously. Cat videos and 90s music are two categories the doctors say are especially popular on WeMesh, which only works with YouTube at the moment, a shortcoming they hope to change in the near future. NOTE: If you're on the Slashdot main page and click the 'Read' link below this paragraph, the video will autoplay.

Advice on How to Start an IT Business (Video) 91

from the if-you're-the-boss-and-you-don't-like-the-boss-you-have-a-big-problem dept.
Lee Drake owns a small IT service and sales company in Rochester, New York, called OS Cubed. He was a cubicle denizen many years ago, and didn't like it. So he started his own business, first with a partner and later as the sole owner. Rochester may be part of the infamous "rust belt," but Lee seems to be doing well, to the point where he's happy to pass on some tips about how to start and grow your own IT business. While Lee's company specializes in "Microsoft solutions," his advice applies to almost any IT business -- and almost any other kind of business, too.

The Oddball Side of CES (Video) 35

In between nodding earnestly as hopeful exhibitors told him how wonderful their products were, Slashdot's Timothy Lord took a look at some of the less-serious displays and goings-on at CES. Some of these people and companies no doubt take themselves 100% seriously, but after grueling days patrolling the endless exhibits at this giant show, Timothy was looking at them through tired (and cynical) eyes. This short video shows some of what he saw.

Drone, Drone, Everywhere a Drone -- at CES (Video) 37

Posted by Roblimo
from the it's-not-superman-and-it's-not-an-airplane-so-it-must-be-a-drone dept.
One thing Timothy noticed at CES was that there were drone vendors all over the place. Drones are obviously one of the hot-hot toy/gadget trends of the moment. The Drone that won 'Best Robot or Drone in Show' was the camera-carrying, "follows you like a dog on a (Bluetooth 3) leash" AirDog. They already had a crazy-sucessful KickStarter campaign that led to a large stack of pre-orders, so don't count on getting your very own AirDog right away, even if you have $1300 to spend on one.

Female-Run Companies Often do Better Than Male-Run Ones (Video) 271

Posted by Roblimo
from the sometimes-the-best-man-for-the-job-is-a-woman dept.
Today's interviewee, Viktoria Tsukanov, is one of the executives at predictive marketing company Mintigo who did a study in January, 2015 that seemed to show that large companies with female CEOs "achieve up to 18% higher revenue per employee than male CEOs." The study, titled "She’s the CEO and She’s Sensational," used financial data Mintigo collected on 20 million companies, and determined CEOs' genders by analyzing first names, so it was not subject to survey vagaries but was a straight data analysis job. Could this be a case of correlation and causation being unrelated? It's possible. It's also possible that the revenue per employee figures are affected by the fact that female CEOs are more common in healthcare and non-profit organizations, while men dominate manufacturing and construction -- and, as Viktoria pointed out in a blog post headlined "Women Just Raised the Bar. Big Time." there may be other factors at work as well.

The "18% higher revenue" figure specifically applies to companies with more than 1000 workers, while companies with fewer workers may average more revenue per employee if they have male CEOs. Besides discussing the study itself, in our interview Viktoria talks about how male employees might want to alter (or not alter) their behavior if they find themselves working for a female boss for the first time. She also discusses challenges a woman might face if she is suddenly put in charge of a heavily male IT or programming staff. Other thoughts she shares have to do with finding mentors and dealing with negative people, both of which apply to people of all genders. Interesting food for thought all around.

Listnr Wants to be 'Your Listening Assistant' (Video) 45

Posted by Roblimo
from the can-you-hear-me-now? dept.
This Listnr is "a new listening device connected to the cloud" being developed by a team in Japan that's currently running a Kickstarter project looking for $50,000 by March 7. The other Listnr "is a free music service helping people discover the best music from independent artists on Soundcloud and Bandcamp." More accurately, that's what it was, since their last Facebook post was in 2011 and their domain name is now for sale. Today's Listnr -- the listening device one -- claims it is able to tell whether a baby it hears is laughing, crying, gurgling or trying to talk. It is supposed to respond to finger snaps, hand claps, and other audio commands. It has an open API so that you can extend its use however you like. The company, too, is working on new applications for their product. Will there be enough of them, and will they interest enough people, to make this a success? Co-Founder Rie Ehara says, "We wanted to build something using sound to enrich and delight our lives." As of today (Feb. 2), Listnr is slightly less than halfway to its Kickstarter goal, so it's still a coin-toss whether or not Listnr will succeed.

VP Anthony Moschella Shows Off Makerbot's Latest Printers and Materials (Video) 47

Posted by timothy
from the now-you-can-make-fake-wood-designer-shapes-on-the-3d-printer-at-your-local-makerspace dept.
You may have read a few weeks ago about the new materials that MakerBot has introduced for its 3-D printers; earlier this month, I got a chance to see some of them in person, and have them explained by MakerBot VP of Product Anthony Moschella in a cramped demo closet — please excuse the lighting — at the company's booth at CES. Moschella had some things to say about materials, timelines, and what MakerBot is doing to try to salvage its open-source cred, despite being a very willing part of a corporate conspiracy to sell boxes of Martha Stewart-branded extruder filament — as well as a few unremarkable things that the company's ever-vigilant PR overseer decreed Moschella couldn't answer on the record for reasons like agreements between MakerBot parent Stratasys and their suppliers. The good news for owners of recent MakerBot models: they'll be upgradeable to use the new and interesting materials with a part swap, rather than a whole-machine swap (it takes a "smart extruder" rather than the current, dumber one). And the pretty good news for fans of open source, besides that the current generation of MakerBots are all Linux-based computers themselves, is that MakerBot's open API provides a broad path for 3-D makers to interact with the printers. (The bad news is that there's no move afoot to return the machines' guts to open source hardware, like the early generations of MakerBots, but STL files at least don't care whether you ship them to an FSF-approved printer to be made manifest.)

Jim Blasko Explains 'Unbreakable Coin' (Video 2 of 2) 39

Posted by timothy
from the is-it-cryptocurrency-or-cryptic-currency? dept.
Today, the conclusion of my talk with Jim Blasko (here's part 1), who encourages you to go start your own crypto currency, because it's a fun exercise and because every entrant adds new ideas to the mix. As you'd expect, he's bullish about both his own Unbreakable Coin and cryptocurrencies more generally; how any given given currency performs, though, is an open question: U.S. dollars, Euros, or Yen may not go experience any meteoric rises, but their stability, even with inflation, is a nice feature, and so is their worldwide convertibility.

Regulation, speculation, fraud, and cultural fashions all play a role in making new currencies risky; reader mbkennel yesterday asked an insightful question: "Are you up to loaning bitcoin or something less popular for 10 years?" Confidence in any given currency can be tested with the terms current holders are willing to accept to make loans payable in that same currency. (On the other hand, if large companies will accept it in payment, they've probably got an idea that a given currency will be around next month or next year.) If you've bought any form of crypto currency, what's been your experience, and what do you expect in 10 years? (Alternate Video Link)

The 'Radio Network of Things' Can Cut Electric Bills (Video) 172

Posted by Roblimo
from the trying-to-bring-the-electric-power-grid-into-the-21st-century dept.
We all love 'The Internet of Things.' Now imagine appliances, such as your refrigerator and hot water heater, getting radio messages from the power grid telling them when they should turn on and off to get the best electricity prices. Now kick that up to the electric company level, and give them a radio network that tells them which electric provider to get electricity from at what time to get the best (wholesale) price. This is what e-Radio is doing. They make this claim: "Using pre-existing and near ubiquitous radio signals can save billions of dollars, reduce environmental impact, add remote addressability and reap additional significant societal benefits."

Timothy noticed these people at CES. They were one of the least flashy and least "consumer-y" exhibitors. But saving electricity by using it efficiently, while not glamorous, is at least as important as a $6000 Android phone. Note that the guy e-Radio had at CES speaking to Timothy was Scott Cuthbertson, their Chief Financial Officer. It's a technology-driven company, from Founder and CEO Jackson Wang on down, but in the end, saving money is what they sell. (Alternate Video Link)

Talk to the World Through Ubi -- and Use Gestures, Too (Video) 38

Posted by Roblimo
from the not-quite-star-trek-but-getting-there dept.
'The Ubi is an always-on voice-activated computer ready to help. Just plug it in, talk to it and it'll help you connect with your world.' That Kickstarter project description back in 2012 helped UBI raise $229,594 even though they only hoped for $36,000. So now they sell Ubis for $299, as you can see for yourself by clicking the "BUY NOW" button in the upper right corner of www.TheUbi.com, their site's main page. A cynic might say that a decent Android phone can perform most Ubi functions, including a growing number of home automation control tasks, and that Android voice recognition gets better with each new release. But Ubi is cute, and round, and "you can talk through it to the ones you love."

That's great, but Android phones can do that, too. What a smartphone can't do is compete with Ubi Interactive, which may finally give us gesture-based computer input that is not only exciting in a Star Trek way, but is also practical for home and business use. This, along with Kinect, looks like a product that has a solid future ahead of it. (Alternate Video Link)
