I know that Android has a way to get location, and W3C has a location API for web browsers, but is there a way to get my location progromatically on my own machine?
I'm running Ubuntu 14.10
Edit: Removed ruby tag. Opening up to any language.
Short answer for your question: with just Ruby - you can't decode your location when working on localhost.
You might try using gem trifle for that, but what it does is a GeoIP country lookup. Because you want to try to decode your localhost - it can't just work.
How it works is - it has a database of IP's and associated cities. This will work when you deploy the application, and it will try to decode your visitor's locations.
Example in their github is quite easy. Once your trifle gem is set up properly (it requires redis server, and loading provided file with predefined IP's and associated cities):
trifle = Trifle.new(Redis.new)
trifle.find "223.255.128.0"
# => ["HK", "Hong Kong"]
# or you can try to play with it in controller
trifle.find request.remote_ip
What you can do, to decode your location when working in locahost:
There is a way to obtain location of computer accessing your application using browser's capabilities. There is a great article in tutsplus - http://code.tutsplus.com/tutorials/an-introduction-to-the-geolocation-api--cms-20071. This will work with localhost
There is quite long code presented, so I wont copy it here, but explanation is very good. You can easily implement your solution based on the article, and the location is very accurate. The limitation for this is - browser asks if it can obtain location of computer, and user might not allow that operation. There is no way for forcing it.
Hope that helps!
Good luck!

I am looking to implement First Click Free in my rails application. Google has this information on how to verify a if a googlebot is viewing your site here.
I have been searching to see if there is anything existing for Rails to do this but I have been unable to find anything. So firstly, does anyone know of anything? If not, could anyone point me in the right direction of how to go about implementing what they have suggested in that page about how to verify?
Also, in that solution, it has to do a lookup every time to try and detect google, that seems like its going to be a big performance hit if I have to do it every page load? I could cache the IP if it has been verified in the past but Google have stated that their IP's change so at some point it may no longer belong to them. Although it probably doesn't happen regularly so it may not be that big of an issue.
Many thanks!!
Check out the browser gem: https://github.com/fnando/browser
What I'd do is use the
browser.bot?
method to check if your site is being accessed by a bot or not. If you care about the Googlebot specifically, you could check if
browser.name
includes googlebot. Keep in mind that this gem just checks the user agent sent by the client's browser, which could of course be spoofed. Sounds like that isn't a huge concern for your purposes.
I've built a Ruby gem for that recently, it's called "legitbot".
You may learn if a Web request comes from a supported bot using
bot = Legitbot.bot(userAgent, ip)
"legitbot" does this looking into User-agent and searching for a bot signature, i.e. how bots identify themselves. This doesn't guarantee that the Web request IP really comes from e.g. Googlebot. To make sure it is, call
bot.detected_as # => "Google"
bot.valid? # => true
bot.fake? # => false
Supported bots are Googlebot, Yandex bots, Bing, Baidu, DuckDuckGo.
I'm new to web development, rails, etc. I have what is probably a very dumb questions but I searched and was not able to find the specific answer, though there's a good chance I asked the wrong question.
I'm following this tutorial which wants you to create a test rails app locally and view it via localhost in a browser. However I am learning directly on the server itself. This is because currently I only have an iPad to work with, but I've been able to do everything directly on the server itself using Panic's Prompt. To continue with these lessons I need to be able to see what I've done via a browser which since I can't use localhost, I want to see directly on my server. Here is the tutorial I'm following:
http://installfest.railsbridge.org/installfest/create_a_rails_app
Here is my website:
redvardo.com
Any help or pointers toward the correct information would be helpful. Please tell me if I did not include enough information as well. Thanks!
If your server provides a public IP address, use that ip to access the project. First of all make sure the brick server is running via rails s then you can go ahead and access the page directly via the ip: 12.13.31.115:3000 for example. This would be the fastest way, otherwise you need to setup dns to point to your server via your domain name registrar.
Hope that helps.
Thanks for the help but for me, what I did was simply install a VNC server on the server itself, now I can view localhost on the server for everything the tutorials are asking.
I'm currently developing a server that can get data over the internet from specific device i have and log it into a database. Unfortunately I dont have control on the way this device communicate.
Currently I set an IP adress and a port number and the device will open a socket and send a string. I dont really want to develop a server from scratch and i would much prefer to base on a web server. but the data is a plain string and not a full http request.
Is there a way around it using Ruby on rails ? Is it possible to do with other web-server-based technology ?
Thanks a lot
You can use just a regular old ruby socket to receive the string.
Sounds like an application that node.js would be useful for, if you want a pre-made node+rails app which would do what you want check out compound at GitHub mentioned in this article
I am just looking for the best solution for the following problem.
I have installed wordpress mu, and I wanted to create child blogs, for different areas in the world. But I want it so 1 domain can switch them instantly using the users ip address.
IS there a extention of wordpressmu or buddypress or do I need something on the server say in htaccess to do that?
Check this plugin out: http://wordpress.org/extend/plugins/ip-to-country/
You could possibly use this, check the value returned, and set a WordPress cookie for the user that automatically redirects them to the geo-specific blog and will do so if/when they return to the site.
Check out the Google API for geocoding, user detection, and geogrouping options (redirect all users from combined location like 'Europe'). Rather then doing all the heavy lifting on your server, work with the Google API, get your nicely formatted answer back, and redirect based on that....
Anything that involves geographical relation .... GOOGLE GOOGLE GOOLE
I can't figure out what I'm overlooking, perhaps it's obvious or lack of understanding.
The app I'm working with uses subdomains which on the hosting server work properly. I figured locally installing would kick up some issues around routing, so I read up on making changes to /etc/hosts and using the Ghost gem. Both seem to work fine i.e. localhost:3000/ becomes myapp.local:3000 but I don't understand how to go about logging into a subdomain account. Here's an example...
myapp.local:3000/session/new = the default login page for the app
myapp.local:3000/signup = default signup page
I can create an account here e.g. Sub1
The thank you page is shown w/ the reference to sub1.myapp.com which points to the hosted app (the local db shows this domain as well)
sub1.myapp.local manually added to /etc/hosts and dscacheutil -flushcache
sub1.myapp.local:3000/session/new is the subdomain
login attempts return that this isn't a valid domain. This seems to make sense because the local db shows the url as sub1.myapp.com on the hosting server.
So my question is whether there's a local workaround that I can use for development or have I totally missed a fundamental concept along the way?
you might just want to try putting the actual dot com in your /etc/hosts file.
ie:
127.0.0.1 sub1.myapp.com
127.0.0.1 myapp.com
127.0.0.1 anyothersubdomains.myapp.com
what this usually does is trick your computer into thinking it is the host of all of those, so you can't go to the real site anymore in a web browser.
if you do want it to be .local, presumably so that you can refer to the real online site while working on a local copy, you should probably take a look in app/controllers/application_controller.rb (sometimes application.rb) and look for logic in there that helps determine what to do depending on the subdomain. maybe its hard coded to only look for a .com or something.
If you are using the webrick server or something like Puma for development you can use lvh.me to access your subdomains. e.g.
http://sub.lvh.me:3000/
http://lvh.me:3000/ is equal http://localhost:3000/
