I am using Rexml for reading the RSS feed and is working fine with small size of feed.
The large size feed is not working on device although working fine on simulator.
How can i handle large size data?
To read RSS feed, why are you using Rho::AsyncHttp.download_file().
use Rho::AsyncHttp.get().

Arduino programmer; I have a NANO33 programmed to read National Weather Service and Air Now AQI data and show it on a 16X2 LCD screen. I’m using HTTP and JSON to read and parse the received responses using C++. Now I want to display all the data using HighCharts. I see that HighCharts supports the Python platform; does it also support the Arduino?
You can find all information about available official and community wrappers at the following website: https://www.highcharts.com/blog/wrappers/ .
Take note that Highcharts is a JavaScript library based on SVG rendering, dedicated to displaying graphs in a browser. You can also generate raster and vector images using an export module (https://www.highcharts.com/docs/export-module/export-module-overview).
Perhaps the solution would be converting chart images to Arduino array using some LCD Image Converter.
We are developing an application to record short video snippets with the HDR-AZ1 and so far can only transfer images. We also need to transfer the mp4 files, but cannot find the documentation to perform this task. Has any one implemented a solution for transferring video from the HDR-AZ1?
Take a look at the documentation in Sony_CameraRemoteAPIbeta_API-Reference_v2.00.pdf on Pages 18 and 20. These describe the APIs necessary to transfer video files.
I am building and app that will need to parse several RSS feeds, so I am trying to get this theory sorted in my head:-)
I am reading up on NSXMLParser and I have had a look at MWFeedPaser.
Looking at all that code I understand it is going to take time before I understand what it exactly doing.
My initial Idea was to populate a Plist with RSS Links as I have categories that have different feeds and that way I would be able to manage that.
Is that a bad way to go?
What are the pro's and con's of Plists in this scenario??
The App is designed in a UIViewController using a TableView rather than a UITableViewController if it makes a difference.
Thanks for any advice.
What is the best option for storing large amounts of data locally (such as images) in a PhoneGap application on iOS?
I am also using jQuery, jQuery Mobile and backbone if that matters.
make a phonegap plugin, and write to a file on the ios filesystem with phonegap plugin mechanismhow
If you can somehow transform your images to base64 (I download them from my server like that), you could also save them using PhoneGap's storage API. This works quite nicely from my own experience.
Keep in mind however that there is/was a nasty bug in Mobile Safari that would crash it completely when you load a lot of images into the view. Not sure if this has been fixed since.
You have a few options. How big is large? If it's about 2-3 megs, then localStorage is an option. The max size for most implementation is 5MB and this is shared amongst websites.
On the native side, you have NSUserDefaults and CoreData. Either one you use, you'll need to create a plugin for interfacing to the native side.
You can use the File api to store images and text files to the local filesystem. It works absolutely fine.

I am working with the iPod library on iOS to access audio for an audio player app and to properly test my system I need to generate a large number of test data. This means lots of mp3 files (and AAC/iTunes Plus) with unique meta data (id3) so that I can test loading up a large number of tracks to ensure it does not crash the app. My personal collection is less than 3000 tracks so it is not a fair test for users with 64GB iPhones that are loaded up with well over 10,000 tracks.
My initial plan would be to create a short 5 second audio track and set the meta data with artist, album, genre and other details. I would do this in another account on my Mac so that I would not interfere with my personal iTunes library. I would then sync this library to my iPod for testing.
Is there already a way to generate a test library with a large number of files with unique meta data? Is there an iOS compatible id3 tag library that I could use?
I've searched GitHub and did not find an Objective-C library for setting id3 tags.
Well, you can find loads of free mp3s at: http://mp3.com/
