React Native at a Glance

I’ve been looking at React Native as a tool for cross-platform mobile app development.

Reactive Native is supported by Facebook. It’s written in Objective-C from Apple.  You code RN in Javascript and JSX. The cool thing about RN is that your Apps are true Native, not web apps or hybrids. It compiles to Native code on both IOS and Android.

My conclusion is that React Native is a pretty good way to have one UI of views and elements that work the same on both IOS and Android. If your App is limited to basic functionality and you have RN components that do what you want, then RN is a good solution. And if your App uses APIs that build server-side content, then take a serious look at RN because it is strong on HTTP and Javascript CRUD.

Let’s dig a little deeper. I’m working at an App that does image AI recognition and style transfers. React Native does not have support for these new technologies on either the Android or IOS side.

But it is possible to build your own Swift and Java Components for React Native. Here's the gotcha. The Swift component will not run on Android, and the Java component will not run on IOS. So you are back to platform-dependent development where RN is lacking.

It is also possible to integrate RN modules into existing Swift and Java Native Apps. That's correct. You can add common RN Views to your existing IOS and Android Apps.

So when deciding on React Native, you need to ask yourself these questions:

1) Should my App start as a React Native App or a Native App?
2) Is React a good time saver for the common UI that I need?
3) How much platform-dependent module code do I need to write for IOS and equivalent Android?

Conclusion:

If you are writing an App without too much high tech platform dependencies, then React Native should work. Or if your App uses a lot of back-end APIs that do most of the work, then RN could be a great solution. But if you have a complex App that uses a ton of non-RN supported code, then you are probably better off building two versions of your App, IOS and Android Native.

Making Stuff

While working at Los Alamos on the secret Manhattan Project, Richard Feynman was earning just $380 a month. This was half what he needed to cover his living expenses and his wife’s medical needs. On weekends, Feynman drove to Albuquerque to see his ailing wife in a car borrowed from his friend Klaus Fuchs. 

When asked who at Los Alamos was most likely to be a spy, Fuchs speculated that Feynman, with his safe cracking and frequent trips to Albuquerque, was the culprit. Fuchs later confessed to being a spy for the Soviet Union in 1950. Some speculate that Feynman caught him. I agree. 

But many in the FBI kept records on Feynman. They believed he was a communist spy. 

Feynman could explain complex issues with the gift of metaphors. He eventually became a teacher.  Perhaps the best physics teacher ever. 

On politics Feynman once wrote to his wife “Nobody has ever figured out the cause of government stupidity—and until they do (and find the cure), all ideal plans will fall into quicksand.

As American politicians turn back toward fossil fuels and away from solar, I’m pretty sure I know what Richard Feynman would think. “It isn’t the stuff, but the power to make the stuff, that is important. But I realize now that these people were not in science; they didn’t understand it. They didn’t understand technology."

Inherit the Wind

So you think the Earth is real? The real question is which of us are players, and which of us is code? This is an excellent video if you dare watch. If you want to inherit the wind.

We finally have the theory of everything. There is no Fermi Paradox if we live in a world of alien creation, but what if we are living in an ancestral simulation created by our future selves?

With billions or unknown numbers of simulations, a sci-fi novel about a real base civilization would require imagination. How did they survive? What is their physics? I’m writing about a base as a sequel to Rainhut. Rainhut was about us living in a simulation. I believe a base must have created a form of quantum computer and then hit singularity before destroying themselves. I'm curious to know where the first came from and how they did it, how they built the first simulation.

Are there endless worlds for the makers to explore? Is there a Gateless Gate, a Mumonkan? 

Is it possible that Simulation Theory will someday be taught in school like evolution is today?

Entirely New Art Form

The picture on the right was hanging on my wall. I trained it as a style transfer model and then applied the model to the picture of my daughter on the left. The model was built with TuriCreate and I wrote the software in Swift with CoreML.

Best Camera has asked me to review several Apps that use machine learning and style transfers for this new art form. Some are very creative.

Here is a link to an article I wrote for Apple about TuriCreate.  

TuriCreate Style Transfer That Works

AI Creative

So you think Artificial Intelligence is incapable of creativity and that it will destroy the Earth? Well, at least we won't be destroyed creatively. On the other hand, what if AI understood the futility of Nuclear Weapons and helped humans evolve? What if it helped us to fly beyond our small rock?

At IBM they are on a quest for AI Creativity.

Marco Polo

My daughter introduced me to the Marco Polo video walkie talkie App. It’s hillarious. This is a non-interactive video messaging solution.

Marco Polo makes it easy to send selfie video messages. Use it anytime. Make a quick video short. Your recipient contact receives a notification once you’ve started recording your message, They are able to watch you live or watch later.

The App has video filters to make you look cool and voice alteration for funny voice response. I find myself using the helium voice because it makes my kids laugh. To change the video filter, swipe left and right on the screen.

I find this App more convenient than FaceTime. You don’t need direct contact and if you don’t like your message, just redo it. And sometimes it’s easier and faster to send a quick video instead of typing on your mobile.

About Wattpad by Rob Adamson

Checkout Wattpad. I post articles occasionally here on Best Camera along with other writers, photographers, and coders. I thought it would be fun to tell you about Wattpad. This is a site where writers publish chapters of their books as they finish them. They receive feedback from other writers and readers.

This service is pretty slick. And they have a companion App.
