If nothing else, Ionic 2 does an amazing job at emulating a wide array of native controls for both iOS’s Human Interface Guidelines and Android’s Material Design with a single HTML component. I think most of the progress has only been made possible with the advancement and adoption of newer CSS standards that make some of emulated effects like animations, layouts and effects practical.

Ionic 2 is also dependant on Angular 2 which is nice hefty upgrade that makes Angular a bit more structured and performant. While the learning curve is steep (knowing Angular 1 probably makes it even worse), the native TypeScript support means everything is strongly-typed and documented. (TypeScript is easily Microsoft’s greatest contributions to the web development community)

Debugging an Ionic app either running in the browser or running on a phone with Chrome’s DevTools is absolute bliss. electricity and magnetism worksheets 8th grade Not only can I inspect and edit the HTML contents, CSS styles and Javascript live. The Ionic CLI also takes advantage of LiveReload to instantly refresh CSS changes without a new build or deployment. A pixel-perfectionist’s dream. electricity calculator Publishing to Google Play

Up close, it’s definitely not discreet. Not only does it audibly make many loud beeps during its systems initialisation but when the blades are spinning, it sounds like a hovering hairdryer. However at a distance of about 30 meters (which is the recommended safe distance from other people and property in Australia), it is only subtly noticeable.

Of course with great power comes with even greater battery demands. I was able to get around 20 minutes of flying time on each battery which includes the roughly 5 minutes of safety buffer for return-to-home which is a safety function that can automatically fly the craft back to the takeoff position at critical battery levels. A second battery is pretty much required for any practical uses.

The camera on this system is actually the same camera DJI has on their professional-grade Inspire 1 quadcopter at 3x the price (the biggest difference is that the Inspire 1 has retractable feet so the camera can rotate freely, whereas the Phantom 3 must rotate the craft). It also captures in DNG RAW still format and LOG-color videos for professional color grading which takes some time and effort to post-process, but the results are worth it.

Of course it doesn’t help that silly people have done dangerous things with remotely controlled aircrafts of all shapes and sizes, now there’s some pretty easy to understand guidelines in most countries now surrounding recreational unmanned aircrafts. electricity and magnetism worksheets 5th grade However there’s still quite a bit open to interpretation, which is why you have to dig deeper into the actual laws and regulations.

I’ve already spent half a dozen nights reading and re-reading the Civil Aviation Safety Regulations Part 101, emailing the Civil Aviation authority for clarifications, and researching airspace and airport maps and I’ve only begun to understand the actual regulations in place for what is and is not allowed which is quite a bit more explicit and complete than the generalised guidelines. I would highly recommend anyone who is looking to fly in Australia to do the same.

The industry has also been pretty good at proactively adding safety features and limitations to its products to prevent dangerous and illegal activities. I expect the next generation of quadcopters to adopt many more sensors for obstacle avoidance so that even user-caused accidents like flying into people, property and objects can be prevented.

If you’re somewhat serious about photography, then I highly recommend the DJI Phantom 3 Professional as a treat for the holidays. It beats the hell out of a selfie stick. Not only is it fun and simple to fly, it captures professional-grade photos and videos with very little effort. gas house And like prosumer photography, prepare to spend a lot of money on accessories.

I listen to a lot of podcasts, audiobooks and music on my daily commutes. I have been content with generic headphones for as long as I’ve owned phones and media players. I’ve always thought noise-cancelling headphones were a luxury only for long international flights, it never occurred to me just how big of a difference they can make even for a simple train trip.

The headphones come in a carrying case, two colors (black and white) and two models: one made for Apple devices; and another made for Android devices. There’s no difference except the inline microphone & remote are optimized for each platform. In fact I suspect because it uses a standard 3.5mm TRRS conductor, it should be cross-compatiable with any modern smartphone.

The design and build of the QC25 feels solid and sturdy but weighs just 200 grams. The retractable headband is easy to adjust and holds its place firmly with thin etched slots. gas tax by state The rotatable hinges that allow the headphones to be folded into itself is metallic and covers the cord so it can’t be damaged. I throw these in my computer bag without the case day after day and they still look like new.

The QC25 is one of the most comfortable over-ear headphones I’ve ever tried. Whereas some over-ear headphones I’ve tried actually clips my earlobes (and bruising them after extended use), the QC25’s elongated oval cups cover well-over the entire ear. The thick leather cushions form a tight seal around the ears, but it’s soft enough it doesn’t feel like it’s pressing hard against you.

Gone are the thumps of train wheels on train tracks, the high-pitched whine from electric train inverter, the over-enthusiastic passengers who love to chat and the roars of a diesel engine on a bus? Gone. You can still make out beeps of a train door closing, someone talking directly to you and the barks of a dog, but it’s significantly quieter. This headphone has been systematically rated as one of the best noise cancelling technologies available today and I don’t doubt that.

The worst thing about the QC25 is the unnecessary long cable – it’s roughly 50% longer than Apple’s Earpod cables. I know it’s an odd thing to say about a pair of headphones, but the dangling cable is a real nuisance. gas after eating yogurt It flails about when I’m walking and I have to tuck a good portion of it in my pocket where the magical knot-fairy does its best work. There’s scientific proof longer cables have a higher knot probability.
