Hi folks, I have an app that I'm trying to develop, but I'm finding difficulty selecting an app development framework. The app basically requires users to create a profile, and store encrypted data on a cloud. I'd like to use AWS.

I've tried Phonegap - but it doesn't seem supported by their dev team. I can't even launch the desktop app on Windows 10.

Tried React Native with Amazon Amplify and AWS. There are too many errors and deprecated dependencies in their sample projects (with the tutorials I tried). Only seems to be 1 developer advocate at AWS who is contributing to React Native + Amplify tutorials.

I had a look at Xamarin Forms. The samples on Github were updated between 2 and 5 years ago: https://github.com/awslabs/aws-sdk-net-samples/tree/master/XamarinSamples

I would appreciate any advise or links to sample code repositories (with authentication functions) to get me started, on a framework that is supported. Ideally on AWS.

Hi All.

For the past few months I've been struggling to find a solution to creating a sub-$200 realtime HD video warping solution.

I'm developing a curved display product and I need a solution to perform geometric correction of regular flat/rectangular content so that it appears fine on the curved surface.

To perform the warping I can do it at various levels:

1. At app level utilising software that incorporates the warping for specific purposes (I've got a few that do this).

2. Using desktop warping software. I've come across $500+ warping solutions for Windows, Mac and Linux. Noting on Android. These solutions are not user-friendly

3. Utilise an existing commercially available warp box. A/V providers who have digital scaling solutions supply these. They're pretty expensive: $3500+

4. Find a projector with built-in warping capabilities - these are generally $4000 to $17000

5. Build my own warp box: I've found semiconductor companies with chips that perform geometric correction. However they only supply evaluation boards. To design my own PC Board with HDMI-in & HDCP that warps the content and outputs via HDMI is probably going to cost beyond $10k after development and certification.

6. Use an Android Media Player with HDMI in/out and HDMI passthrough capability to warp the content in realtime utilising OpenGL mapping techniques. I've been searching for a freelancer on various platforms that can help me do this on an Android Media Player that I believe offers the potential to be a low-cost warping solution but to-date I have had no luck in finding a developer that can do this. The gig: https://www.upwork.com/jobs/~01ee348a91b5cca1a9

Is their anyone on HN that can suggest a viable warping solution and/or help me develop it? Will pay for it.

Hi. I'm trying to design a solution that can be fed an HDMI signal, in real time warp the image for a curved surface and output the image via HDMI. There is software that can warp a video on the fly on VLC. First step: Figure out if I can warp streamed video using that plugin. Second step: Warp cable or gaming video.

Someone has developed a UVC Grabber solution for Rasbperry PI 2 that allows you to feed in HDMI via a USB port. However, the video quality isn't that great (as expected). I've seen HDMI Gaming Video capture devices on the market, but I'm not sure if they will do.Also uncertain if the IntelNUC 5 kit (http://www.intel.com/content/www/us/en/nuc/nuc-kit-nuc5i3ryh.html ) would work. My day job is solution architect (more so on software side) - I'm not too familiar with processors. GPU's and circuit boards. Any advice on either retail solutions that can do what I need (I've seen some Live Media Broadcasting solution - highly pricey), or platforms I can build on?

Hi. I've tried and failed at many attempts to launch new tech solutions over the past decade in Johannesburg. I think the problem is that I haven't found the right people to partner with, or we get distracted too easily in this metropolis. The only successes I've had is running some blogs (and I'm now learning how to outsource some of the work to online freelancers). One of my friends suggested I go to Bali and try to find like-minded entrepreneurs to work with. I found this article and it looks very interesting: http://tech.co/reasons-to-startup-in-bali-2014-04

Are there similar places I can join? I've taken part in a few 48hour startup events before and joined some fairly limited Meetup events in mu city. Something like joining an incubator doesn't feel appropriate at the time (too soon). I'd appreciate any suggestions.
