i am a newbie with the esp8266 and the esp-touch looks like an excellent way to setup my IoT gadgets. I just found out that it was disabled in the new SDK. I would like to know what is the reason so to decide if to enable and use it and what other options can i use if its not a recommended way to set up my projects.
thanks
It has a heavy runtime footprint, and few users use the API so it is now disabled by default, but can be enabled via user_config.h setting.
PR which disabled it and link to discussion: https://github.com/nodemcu/nodemcu-firmware/pull/1104

I wondered if anyone is aware of anyway that I may modify the communication settings of multiple Twitter accounts. Basically I have a number of accounts which all currently receive info at twitter emails etc and I'd like to manage these communication settings in an automated fashion but this doesn't seem to be possible.
I wondered if there is any way to do this in an automated fashion?
I'm using LinqToTwitter http://linqtotwitter.codeplex.com/ project to talk to the Twitter API in C#, although I don't necessarily have to use this.
I'm currently starting to think of using Selenium to do this.
Does anyone have any thoughts.
Many thanks,
Andy
There are some application settings you can manage through the API. In LINQ to Twitter they're mostly available by querying on the Application entity. However, there aren't any email preference setting options that the Twitter API offers.
My experience is that these settings options tend to change over time, mostly additive. So, whatever you come up with, you'll probably need to revisit your implementation occasionally to adapt to these changes.
I'm building a Rails app where I need a real time commenting system. I'm going to use WebSockets, but I'm new to them and I'm kinda lost. I tried em-websockets and websocket-rails, but neither worked well with what I have to do. I also though of a Node.JS and Socket.io app, but I don't know how to start with that.
What I want to do is send a WebSocket message when a new comment is made on a post, on the create action of my CommentsController. I'll send a message containing the comment content and creator and the post ID.
Thanks in advance! :D
Sorry, but I dont think so. Be careful with WebSockets. It is fundamental concept that provides a very powerful mechanism.
Websockets is good for super, absolutely real-time applications like online games. For commenting system (even realtime) you dont need them, the AJAX is more then enought for this.
You could use a realtime hosted service if you don't want to deal with your own realtime infrastructure, fallbacks for older browsers, scaling complications etc.
I recently wrote a post on Smashing Mag on building a realtime commenting system. It uses PHP and Pusher (who I work for) but the separation between client and server should meant that you could use any backend technology/service. It also demonstrates how to progressively enhance your app.
The most commonly used self-hosted ruby technologies for realtime communication does seem to be Faye, as #Alfred suggested.
Just using websockets as the only available transport is not a good idea, because websockets are not yet supported in every browser. Luckily for example Faye does support multiple transports so that it will work in every browser. I also found this interesting video in the past explaining how you could use Faye in conjunction with RoR from RailsCast.
I am in the planning stages of building an App for iphone / ipad (yes, very early stages)
I am basically wondering how much work is involved in having a seperate user registration process for an app i.e. letting users register an account and use login using that account and use the app.
Will this involve constructing / coding an entirely new database or is there software available that automates this process?
thanks in advance
You could have a look at a service like StackMob.
This allows you to utilise server based services with no server-side implementation on your part.
These guys here: parse.com are doing a great job to facilitate developers the setup of a cloud database to do many tasks that are common in iOS apps.
In particular there is a section dedicated to user management (sign-up and sessions) that is well described here: Parse iOS guide
Finally the service offers some user interface help also, look here even if probably it is better to give to the UI some personalization by coding your own UI.
There are some implementations, but if your app is going to have custom code executed by server, you'd better make your own code.
Use a server side language (php, perl, ruby, python, java) to do the registration.
You'll probably need a REST service and/or json if you are going for easy peasy stuff (if you are to web apps programming). Otherwise, you'll need to do xml parsing and other stuffs. Use asi-http for the interactions between server and the app, or if you are using ios5.x it has already a json parsing implementation.
I know this a pretty general question and I'm not looking for code or anything. Even a link or short explanation would be nice.. Specifically searching for a way to browse network based active directories from an internal IOS application. Using a cloud or email is not an option.. Possible?
There is a recent article on IBM developerWorks that explains how to use OpenLDAP client libraries in the iOS environment. You can use OpenLDAP client libraries to access LDAP sources, including Active Directory. Not all Active Directory operations are supported, but even basic queries should be sufficient for building a browsing application.
There is a recently released free solution called Centrify Express for Mobile that allows an iOS device (iPad/iPhone/iPod) to join Active Directory, so you can use AD to manage/secure the iOS device.
Webmachine seems like a great system to build REST web services, but I know it does not provide websocket compatibility. My question is rather straightforward : What would be a good approach to add websocket capabilities on top of a web service built with webmachine?
I'm running Misultin alongside Webmachine for that exact matter.
For easy use websockets in webmachine I implemented that by changing sources of webmachine (adding support mochiweb_websockets ) and mochiweb (add support secure websockets).
You can download from git full solution (webmachine with websockets support) by this link:
https://github.com/Dryymoon/webmachine.git
And by this link example usage of solution.
Or if want dig a little deeper:
I changed only two files of sources:
1) webmachine_decision_core.erl changed (add support websocket handler).
2) mochiweb_websocket.erl (add support secure websockets and patch existig).
Late answer, but just stumbled upon this, but another option is to run SimpleBridge (https://github.com/nitrogen/simple_bridge), which adds an abstraction layer (conditionally bypassed using webmachines routing system) which adds websocket support to any erlang webserver it supports (includes webmachine).
