SuperComics V2: Modo developer
Apple acaba de aprobar SuperComics v2 para iOS con lo que completo las 3 principales plataformas de aplicaciones: Android, Windows Phone y iOS. Finalmente, cumplo con entregar una aplicación que soporta casi todo lo que hay en el mercado con una sola base de código. Aún en el horno está la versión para Windows 10 y para cuando le encuentre la forma de monetizarlo, la versión Web. La motivación…

Allowing CORS from a Node-Red Bluemix application
Allowing CORS from a #Node-Red Bluemix application #nodered #bluemix
I wrote a rating application some time ago in Node-Red and have since needed another similar application but with slightly different behavior. So I went ahead and created a new Node-Red application on Bluemix and decided to start from scratch since it was so simple to set up. This application has three requests – Get Rating, Post Rating, and Post Comment. Here is the current flow:
The problem I…

Searching a Cloudant DB search index with Node-Red
Searching a Cloudant DB search index with #NodeRed
After much searching the internet and seeing multiple posts about this subject I can only think that many others are greatly confused with the use of the Cloudant In node in Node-Red. I think my problem was terminology and not being familiar enough with the Cloudant nomenclature more than anything and the user interface in Node needs a little more work.
I basically want to return all documents…

Ionic Framework, PouchDB y Cloudant: la combinación perfecta totalmente expuesta parte 11
Esta es una continuación de la serie sobre desarrollo en móviles que comencé aquí. Les recomiendo comenzar a escribir el código fuente desde la parte 1 ya que no se publica el código para descarga. Con la parte 10, podríamos decir que comienza una nueva etapa del código así que debemos empezar con las cosas interesantes. Primero planifiquemos las siguientes funciones: Alertas ante nuevas…

Ionic Framework, PouchDB y Cloudant: la combinación perfecta totalmente expuesta Parte 03
Ayer publiqué dije que iba a publicar un nuevo post para contestar una pregunta que recibí en la semana. Notarán el post sobre tips para rendimiento donde la moraleja resumida es que preocuparse por la velocidad de PouchDB contra Sqlite es detenerse en el arbol en lugar de apreciar todo el bosque. La primera pregunta que recibí fue sobre como hacer para recuperar una lista de objectos y luego…

Ionic y PouchDB: tips para rendimiento
En la semana he recibido un par de consultas que me parecen super importantes y que trataré de responder en un par de post y de pasada repasar los fundamentos. La segunda pregunta que recibí creo que es mejor tratarla primero: ¿Ionic con PouchDB y Cloudant es más rápido que usar MySQL y websql? Veamos, desde mi punto de vista por más que parece lo mismo, no lo son. Antes debemos revisar un par de…

Learn before you do, but make sure what you’re learning is right
Started this blog a month into a 2 month internship w/ IBM... better late than never? Here's the problem I see with what I'm tasked with, but first, before problem, background. I'm currently tasked with providing visualized analytics on a cloudant data store that has test metrics data from a test web site for a new initiative from CDS (CLOUD DATA SERVICES). Most of the data are just documents that have arbitrary values for each key. This data has been accumulated throughout the development process so to say that the data has any sort of real life application is obviously not the case. How I've implemented this task? tough answer - as it turns out, a guy from dev advocacy has been building a d3 couchapp (remember, cloudant is built on couchdb) and I could "leverage" (kill me now) the work he's done and just auto-create some views and dump it into our cloudant instance. I followed the readme and got it pushed and was given a nice little URL to click on to see my first couchapp... then I went to the page in IBM Firefox (IBM has their own firefox?) and well, the first problem was that the UI was a mess. charts running off the page, text on top of text, the whole kittin' kabootle. the second problem was that only 2 (bar graph and pie chart) of the 4 (bar graph, pie chart, line graph, and table) types of charts worked. So naturally, I took a peek at app.js... APP.JS WAS A NIGHTMARE. APP.JS was not production ready. app.js and the rest of the code was prototype code... so I started fixing it. Fixing the UI, getting the charts to work. finished some of this, but not completely. talked with team leader? what did he say? he said now try to DECOUPLE THE COUCHAPP FROM THE UI/D3 ANALYTICS. ok, first of all.... couchapp is a css/js/html wrapper that ties your web app nicely together in a cute little json document and then pumps it into your db for HIGH SCALABILITY ACROSS CLUSTERED NODES... but I didn't know any of that then, so I said "sure I'll give it a shot!" and as it turned out... COUCHAPP WAS HIGHLY INTEGRATED INTO THE REST OF THE HORRIBLE D3 JS/CSS/HTML APP THAT DEV ADVOCACY MADE. I couldn't do it, just couldn't. So then team leader suggests I try to do it myself. SURE THING, BRO. I CAN DO THIS. i can't, i definitely can't. well, I started by creating a node.js app. I figured that I needed to create some sort of local web page (which would then later deploy to our org in IBM BLUEMIX that is already running the proof of concept UI EVENT -> KAFKA -> CLOUDANT pipeline) that had a couple of charts and a bit of data to sprinkle in. I figured I could use the cloudant/node.js library (link below) and then connect in D3 for some pretty charts, who the hell doesn't love pretty charts, and d3 is good at it. I'd toss in some bootstrap (also maybe dust?) and I'd be in good shape. I could be naive, but shit, i'm trying. now it's July 15th, been working on this for the four-ish days. right now all I can do in my app (called it "d3-cloudant) is connect to the cloudant instance and dump all of the docs in a view into a cute little variable I called response (it's the response from cloudant or something? I don't know... if you're thinking bad thoughts about my naming conventions then f off). So I started doing this on a monday, last monday actually, jul. 6th. now it's jul 15th and I'm not much of anywhere and struggling to figure out how everything works, how to use them, how to put a project together, and how to get it to work ,,,,,,,, or something? damn, bad headache. AVANT-garde dev easy answer (obviously) - I haven't really WILL WRITE MORE POSTS LATER ON WHAT I DID IN THE PREVIOUS MONTH BEFORE THIS (i.e. JUNE 8th to JULY 5th).
Using couchimport to load JSON data into Cloudant
Couchimport is a command-line tool written in Node.js that allows CSV files to be imported into Cloudant/CouchDB, with each row in the source file becoming a document in NoSQL database. A recent addition to its feature set allows the same tool to be used to bulk import JSON data too.
Imagine we want to import crime data from here:
https://data.sfgov.org/resource/tmnf-yvry.json?$select=incidntnum,category,descript,dayofweek,date,pddistrict,resolution&$limit=50
into CouchDB or Cloudant. The format of the data returned by that URL is
[ { "category" : "BURGLARY", "pddistrict" : "RICHMOND", "descript" : "BURGLARY OF APARTMENT HOUSE, UNLAWFUL ENTRY", "dayofweek" : "Monday", "resolution" : "NONE", "date" : "2005-05-16T00:00:00", "incidntnum" : "050546220" }, ... ]
We can use couchimport for this, as it handles streams of JSON data easily:
# define where the data should go export COUCH_URL=http://127.0.0.1:5984 # curl the data and pipe to couchimport, specifying # --db - the name of the database # --type - json data # --jsonpath - which part of the json to import curl 'https://data.sfgov.org/resource/tmnf-yvry.json?$select=incidntnum,category,descript,dayofweek,date,pddistrict,resolution&$limit=50000' | couchimport --db cr --type json --jsonpath “*"
This imports the data 500 records at a time using the CouchDB bulk API.
