3D Printing Precision Experiment with a Good Printer – Ultimaker 2

For quite a while here at 4PSA we’ve been playing with 3D printing. Why? Because it’s cool and because there are a lot of applications for 3D printing, even in the cloud. We don’t claim to be 3D printing experts, but we took a power user (read engineering) approach to 3D printing which may be interesting to some of you. So we decided to share some stuff with you in a series of articles dedicated to 3D printing.

In today’s article, we want to answer a pretty interesting question – just what level of precision can you expect from a FDM printer? Fused deposition modeling is the most popular and accessible printing technology. The market is already full of printers and even kits you can use to build your own printer that cost as little as a few hundred bucks. For the test, we used one of the best printers available – Ultimaker 2. And yes, Ultimaker 2 may be worth more than a few hundreds, but it’s still an affordable piece of engineering.

GAM Messenger Only Wants 60 Seconds of Your Time

There’s a new app in town and it only wants a minute of your time. It lets you filter between the messages that are important to answer and the ones that you can simply ignore, and it promises to be the ideal tool for sending time-sensitive content. The idea is brilliant, the design deserves an excellence award, but the execution is utterly terrible.

It’s hard to succeed with just another instant messaging app today. WhatsApp and Facebook Messenger dominate the scene, while the likes of Viber, Skype, Kik and Snapchat act like an electric fence for the top 10 chart in IM apps. However, there may still be room for a contender, but only if the developers clean up their act.

Quantum Computing Makes A Leap Forward As Moore’s Law Approaches Expiration Date

On April 19th, 1965, Gordon Moore wrote a technical paper that predicted the increase of computing power. He initially observed that the number of transistors per square inch on integrated circuits had doubled every year since ICs had been invented, and he later perfected the law doubling time to two years.

This month, Moore’s Law turned 50. To this day his prediction holds true, but it might not reflect reality in a few years from now. The reason? Our need for ever-smarter computers requires that we rethink the way we build them, and perhaps even the way we operate them.

Could Keyboards Detect Parkinson’s Disease Earlier?

Few conditions are as ruthless as Parkinson’s Disease. But what makes this one even scarier is that the wheels are set in motion long before the first symptoms emerge – sometimes as early as 10 years in advance.

New research done by the Massachusetts Institute of Technology (MIT) heralds a new diagnosis technique that might help identify early onset of the condition.

Facebook Launches Fun Video Collaboration App, Riff

As of this year, Facebook decided to maximize the potential of its (our?) content by prioritizing video to make up almost a third of the News Feed. For the first time ever, Facebook videos now exceed the number of YouTube clips shared through the social network. Not the type to rest on their laurels, the Menlo-Park company made another push in the video department this week and released a brand new app called Riff.

Originally developed as a side project by Facebook Creative Labs – the same inventive group who made Slingshot, Paper and Facebook Groups – Riff is here to play catch with Vine, Snapchat, and Hyperlapse. However, unlike other Facebook endeavors, Riff stands to gain some momentum.

Study Finds Wearable Tech Is Poised To Explode In Office Environments

Like desktop computers and smartphones before it, wearable tech now promises to mark a paradigm shift in the way we juggle daily affairs, both personal and at work, and even tackle health-related matters.

People today aren’t flocking to buy smartwatches or tech-infused glasses, but it won’t be long before they do, according to Harris Interactive, a market research firm owned by Nielsen Holdings. The New York-based company polled 9,100 people to determine potential benefits in workplace efficiency, productivity, and safety. They discovered that the number of believers was considerable: 75% of the respondents saw wearables as potentially life-changing in work environments.

Kaspersky: When You Get Hacked, The First Wise Thing To Do Is Pray

At this year’s WHD.global – the world’s biggest event for the hosting community – revered figures in the tech industry booked some stage time to discuss the latest trends, including ever-pressing matters like security.

Keen to hop on the WHD bandwagon with an eye on today’s networked world was none other than Eugene Kaspersky, the CEO of the namesake security company whose antivirus software runs on millions of computers worldwide.

The Russian malware crusader kicked off his video-streamed talk noting that traditional crime is moving into the cyberspace, while established cyber-criminals are getting much better at what they do. In short, malware is on the rise. Hardly a surprise since malware is always on the rise. The more interesting disclosures were yet to come.

Learning How to Code Just Got a Lot Easier

Ever scratch your eyes for not learning how to code as a kid? I do every day. Not only is programming one of the best paid jobs (by far), it’s also a great way to turn brilliant ideas into working applications for everyone to use. By all accounts, you can use it to change the world profoundly.

As if programming itself wasn’t hard enough, there are dozens of different coding languages each with their own particularities that can be used to make a program. Depending on the platform you’re targeting, you’ll have a flurry of tongues to choose from.

Swift – the new kid on the block introduced by Apple at its annual developer gathering in 2014 – lifts a lot of the hurdles generally associated with app programming, and now an app called Swifty promises to simply the process even more for noobs like you and me.
