Lets say you’ve come up with a brilliant idea for some shiny new piece of hardware. You brush up your coding chops, scratch out a design, and set out to build a prototype.

First, you’ll need a programmable chip to act as the brain. Because of the relatively gentle learning curve and friendly community, you go with the Arduino. The problem: your hardware idea requires WiFi.

Until now, that’s actually been a pretty complicated issue.

While it was missing the skydiving antics of last year’s event, Google’s I/O keynote last week wasn’t short on product launches. In between the splashy updates to Google Maps, Search, Android and everything else Google announced, the company also briefly talked about Web Components for a few minutes. While Google’s Sundar Pichai noted that it’s still early days for this technology, he also said he believes that “the vision for it is clear” and that it will allow developers to build “elegant user interfaces that work across all form factors.”

Web Components are clearly a topic that’s close to the heart of a number of Chrome developers. Many of them, for example, cited it as one of the Chrome features they are most excited about at a fireside chat later in the week.

A number of Google engineers are also working on Project Polymer, which aims to write a web application framework that’s built upon the idea of Web Components and will allow developers to use the ideas behind Web Components on browsers that don’t even feature all of the necessary technologies yet.

Joshua Pearce, PhD, is a researcher at Michigan Tech who rearches open source and low-impact solutions to engineering problems. He is also the founder of the Printers For Peace contest, an effort to bring together clever 3D-printed ideas that have loftier aims. You can win one of two 3D printers if you submit a winning project.

We asked Pearce a few questions about his goals for the project and about the future of 3D printing.

John Biggs: Why Printers For Peace?

Joshua Pearce: I think it is clear that low-cost open-source 3D printing has enormous potential to do real good for the world – particularly for the poor as it radically reduces the cost of high-value products like scientific tools and consumer goods. This threatens a lot of entrenched interests because the average Joe can fabricate extremely complex products at home for pennies, which is disruptive to say the least. I have noticed a clear bias in 3D printing news coverage – any advances on the low-end of the spectrum are generally ignored or vilified. The media frenzy about 3D printed guns is actually having terrifying consequences – and I don’t mean the guns. A California senator has already proposed registration, background checks, and licensing for 3D printers!

Sometimes, more medical information is a bad thing. The influential United States Preventive Services Task Force recommends against most women getting genetic screenings for their susceptibility to breast cancer. Why? Because the tests are imperfect: for every woman who gets tested for genes associated with onset breast cancer, even more will falsely test positive, leading spooked patients into needless surgery or psychological trauma. Super cheap genetic testing from enterprising health startups, such as 23andMe, have complicated cancer detection for us all by increasing the accessibility of imperfect medical information.

After discovering a mutated BRCA1 gene, known to increase the likelihood of breast cancer 60 to 80 percent, actress Angelina Jolie underwent a radical preventive double mastectomy. Her brave confession in the New York Times brought much needed attention to breast cancer awareness, but it’s dangerous in the hands of a statistically illiterate population.

For instance, as New York Times statistical guru, Nate Silver, once reminded me, while breast cancer mammograms are 75 percent accurate, a woman who tests positive only has about a 10 percent chance of actually getting cancer. Since the vast majority of women don’t have cancer, there are far more women who will falsely test positive (here is a helpful blog post with the numbers worked out). Most importantly, surveys reveal that many people don’t understand the math behind false positives in cancer testing, and may make uninformed decisions as a result.

Stanford-born and Seattle-based Tableau Software (DATA) enjoyed a tremendous debut on the public markets on Friday, closing on its first day of trading at over $50/share, up over 60 percent from its $31/share IPO price. The company raised over $250 million through the sale of approximately 14 percent of the company, and its enterprise value now sits at approximately $2.5 billion.

For the pundits who’ve been arguing that the tech IPO landscape is in crisis, deals like Tableau serve as a powerful reminder that the public market is eager for certain tech companies. In fact, over the past year or so, there have been several other high-profile tech IPO winners, such as Workday, Splunk, Palo Alto Networks and ServiceNow.

Google is under fire in the UK for its tax practices in the country, and a new key witness (who spoke to The Sunday Times) might put them in deeper hot water when he hands over a reported 100,000 emails and documents to the British Revenue & Customs (HRMC) services. Barney Jones, a former Googler who was at the company between 2004 and 2006, says he has material proof that Google’s London sales staff which would negotiate and close sales for the UK market, despite claiming its Dublin HQ handled finalizing all deals.

Jones was prompted to speak out by testimony given to the Commons Public Accounts Committee (PAC) last week by Google VP Matt Brittin, who said that London-based Google staff were never closing any ad sales deals, though some selling efforts were made there. Brittin had previously gone on record in November 2012 with statements asserting that no one in the London office was doing any kind of ad selling.

The matter of where the deals were finalized is especially important because if a sale closes in London, it’s likely they’d be taxable in Britain, rather than in the extremely low tax-rated Ireland. Jones told the Sunday Times that Google is fully aware of this, yet there are still records of Google staff closing major deals from companies like eBay and Lloyds TSB, but Google doesn’t seem at all certain that any of the documentation will absolutely prove that it has done anything strictly against UK tax law, according to a statement provided by Google Direct of External Relations Peter Barron to the Sunday Times.

YouTube turns eight years old today, reminding each of us in some odd way how young or old we really are. Remember, the company launched back in 2005, the same year that Michael Jackson was found not guilty of child molestation, and Lance Armstrong was winning his seventh Tours De France, and Arrested Development was still on the air.

A lot has changed since then, but YouTube’s growth remains strong as ever. YouTube announced that its community now uploads more than 100 hours of video to the platform every minute. Minute. That’s the equivalent of four days worth of video every sixty seconds.

But of course, the supply makes sense when you consider the demand. YouTube claims that more than one billion people across the world come to YouTube for content each month, which comes out to nearly one in every two people who have access to the internet.

An ancient and once-sacred bond between author and audience, reading and writing have become but two more tasks along with a multitude of other things that we do on a host of digital devices — watcing videos, listening to music, playing games, and really anything except using Facebook Home. Still, there are some for whom the intimate act of interface between pen and paper retains more magic than all the electrons powering all the devices in the world have not been able to recreate. For them, a trio of European crowdfunding projects have trotted out a range of products to improve both endpoints of analog document creation.

Whacked: LazyPete. Arrgh! Listen up, ye scurvy dogs, as I tell ye the legend of Lazy Pete, a pirate so wrapped up in his romance novels that he didn’t see a great white shark leap from the ocean to leave him with just one hand. ‘Tis in Lazy Pete’s honor that Philip Musche surely named his one-handed book reading contraption, which essentially puts one of those book stands that keep pages open on a beefy handle. Despite showing off the reading aid in nearly enough colors to cover the Seven Seas, Musche failed to capture enough crowdfunding booty, and the campaign ended with only £533 of the desired £30,000 treasure.
