  • Sass interface in HTML6 for upload files.

    - by Anirudha
    Originally posted on: http://geekswithblogs.net/anirugu/archive/2013/11/04/sass-interface-in-html6-for-upload-files.aspx[This post is about experiment & imagination] From Windows XP (ever last OS I tried) I have seen a feature that is about send file to pen drive and make shortcut on Desktop. In XP, Win7 (Win8 have this too, not removed) just select the file right click > send to and you can send this file to many places. In my menu it’s show me Skype because I have installed it. this skype confirm that we can add our own app here to make it more easy for user to send file in our app. Nowadays Many people use Cloud or online site to store the file. In case of html5 drag and drop you need to have site opened and have opened that page which is about file upload. You need to select all  and drag and drop. after drag and drop file is simply uploaded to server and site show you on list (if no error happen). but this file upload is seriously not worthy since I have to open the site when I do this operation.   Through this post I want to describe a feature that can make this thing better.  This API is simply called SASS FILE UPLOAD API Through This API when you surf the site and come into file upload page then the page will tell you that we also have SASS FILE API support. Enable it for better result.   How this work This API feature are activated on 2 basis. 1. Feature are disabled by default on site (or you can change it if it’s not) 2. This API allow specific site to upload the files. Files upload may have some rule. For example (minimum or maximum size of file to uploaded, which format the site allowed you to upload). In case of resume site you will be allowed to use .doc (according to code of site)   How browser recognize that Site have SASS service. In HTML source of  the site, the code have a meta tag similar to this <meta name=”sass-upload-api” path=”/upload.json”/> Remember that upload.json is one file that has define the value of many settings {   "cookie_name": "ck_file",   "maximum_allowed_perday": 24,   "allowed_file_extensions","*.png,*.jpg,*.jpeg,*.gif",   "method": [       {           "get": "file/get",           "routing":"/file/get/{fileName}"       },       {           "post": "file/post",           "routing":"/file/post/{fileName}"       },       {           "delete": "file/delete",           "routing":"/file/delete/{fileName}"       },         {           "put": "file/put",           "routing":"/file/put/{fileName}"       },        {           "all": "file/all",           "routing":"/file/all/{fileName}"       }    ] } cookie name is simply a cookie which should be stored in browser and define in json. we define the cookie_name so we can easily share then with service in Windows system. This cookie will be accessible with the service so it’s security based safe. other cookie will not be shared.   The cookie will be post,put, get from this location. The all location will be simply about showing a whole list of file. This will gave a treeview kind of json to show the directories on sever.   for example example.com if you have activated the API with this site then you will seen a send to option in your explorer.exe when you send you will got a windows open which folder you want to use to send the file. The windows will also describe the limit and how much you can upload. This thing never required site to opened. When you upload the file this will be uploaded through FTP protocol. FTP protocol are better for performance.   How this API make thing faster. Suppose you want to ask a question and want to post image. you just do it and get it ready when you open stackoverflow.com now stackoverflow will only tell you which file you want to put on your current question that you asking for. second use is about people use cloud app.   There is no need of drag and drop anymore. we just need to do it without drag and drop it. we doesn’t need to open the site either. This thing is still in experiment level. I will update this post when I got some progress on this API.

  • Gzip compress offline?

    - by shoosh
    I've configured my site to serve compressed content by putting this line in .htaccess AddOutputFilterByType DEFLATE text/html text/plain text/xml text/javascript text/css application/javascript application/json This works perfectly for almost all files except a few large JSON files that are above 200Kb. For some reason they are not being compressed. I see that they don't using the net tab in firebug and the Network section in chrome. So as a workaround I thought I could compress these files offline and have Apache read them compressed. What tool should I use to compress them? is the linux gzip the one? any special flags or something I should use? What should I put in .htaccess so that the server would know to serve these files with content-encoding gzip ?

  • What's the best way to refactor this Rails controller?

    - by Robert DiNicolas
    I'd like some advice on how to best refactor this controller. The controller builds a page of zones and modules. Page has_many zones, zone has_many modules. So zones are just a cluster of modules wrapped in a container. The problem I'm having is that some modules may have some specific queries that I don't want executed on every page, so I've had to add conditions. The conditions just test if the module is on the page, if it is the query is executed. One of the problems with this is if I add a hundred special module queries, the controller has to iterate through each one. I think I would like to see these module condition moved out of the controller as well as all the additional custom actions. I can keep everything in this one controller, but I plan to have many apps using this controller so it could get messy. class PagesController < ApplicationController # GET /pages/1 # GET /pages/1.xml # Show is the main page rendering action, page routes are aliased in routes.rb def show #-+-+-+-+-Core Page Queries-+-+-+-+- @page = Page.find(params[:id]) @zones = @page.zones.find(:all, :order => 'zones.list_order ASC') @mods = @page.mods.find(:all) @columns = Page.columns # restful params to influence page rendering, see routes.rb @fragment = params[:fragment] # render single module @cluster = params[:cluster] # render single zone @head = params[:head] # render html, body and head #-+-+-+-+-Page Level Json Conversions-+-+-+-+- @metas = @page.metas ? ActiveSupport::JSON.decode(@page.metas) : nil @javascripts = @page.javascripts ? ActiveSupport::JSON.decode(@page.javascripts) : nil #-+-+-+-+-Module Specific Queries-+-+-+-+- # would like to refactor this process @mods.each do |mod| # Reps Module Custom Queries if mod.name == "reps" @reps = User.find(:all, :joins => :roles, :conditions => { :roles => { :name => 'rep' } }) end # Listing-poc Module Custom Queries if mod.name == "listing-poc" limit = params[:limit].to_i < 1 ? 10 : params[:limit] PropertyEntry.update_from_listing(mod.service_url) @properties = PropertyEntry.all(:limit => limit, :order => "city desc") end # Talents-index Module Custom Queries if mod.name == "talents-index" @talent = params[:type] @reps = User.find(:all, :joins => :talents, :conditions => { :talents => { :name => @talent } }) end end respond_to do |format| format.html # show.html.erb format.xml { render :xml => @page.to_xml( :include => { :zones => { :include => :mods } } ) } format.json { render :json => @page.to_json } format.css # show.css.erb, CSS dependency manager template end end # for property listing ajax request def update_properties limit = params[:limit].to_i < 1 ? 10 : params[:limit] offset = params[:offset] @properties = PropertyEntry.all(:limit => limit, :offset => offset, :order => "city desc") #render :nothing => true end end So imagine a site with a hundred modules and scores of additional controller actions. I think most would agree that it would be much cleaner if I could move that code out and refactor it to behave more like a configuration.

  • Queuing rpc calls

    - by alfa64
    i'm designing a system wich listen to json rpc calls from clients, piles it up inside a list, and if it gets full it should store them in a DB and keep recieving calls. My original plan is to listen to the rpc calls from Perl with the json-rpc and put them in the array. The clients do some long polling in another server to get responses as they appear. What is this blocking/noblocking thing? Should i do a script for node.js to listen to the calls? What do you think is a good practice in this case? The objective is to listen as much calls as possible.

  • Why do we use networking libraries instead of plain NSURLRequests and NSURLConnection ?

    - by Amogh Talpallikar
    in iOS development, I have often seen people creating a networking module to interact with their APIs. This module generally sits on top of a networking framework like MKNetWorkKit or AFNetWorking. In most of the cases, It's all about sending GET,POST request and parsing the response which is in most cases JSON. What extra practical benefits that these libraries provide that an iOS developer should be leveraging which the plain Cocoa Networking APIs lack ? I can understand RESTKit as one exception where it takes care of the conversion of JSON to native objects and also interfaces with Core Data but what about others ?

  • Are separate business objects needed when persistent data can be stored in a usable format?

    - by Kylotan
    I have a system where data is stored in a persistent store and read by a server application. Some of this data is only ever seen by the server, but some of it is passed through unaltered to clients. So, there is a big temptation to persist data - whether whole rows/documents or individual fields/sub-documents - in the exact form that the client can use (eg. JSON), as this removes various layers of boilerplate, whether in the form of procedural SQL, an ORM, or any proxy structure which exists just to hold the values before having to re-encode them into a client-suitable form. This form can usually be used on the server too, though business logic may have to live outside of the object, On the other hand, this approach ends up leaking implementation details everywhere. 9 times out of 10 I'm happy just to read a JSON structure out of the DB and send it to the client, but 1 in every 10 times I have to know the details of that implicit structure (and be able to refactor access to it if the stored data ever changes). And this makes me think that maybe I should be pulling this data into separate business objects, so that business logic doesn't have to change when the data schema does. (Though you could argue this just moves the problem rather than solves it.) There is a complicating factor in that our data schema is constantly changing rapidly, to the point where we dropped our previous ORM/RDBMS system in favour of MongoDB and an implicit schema which was much easier to work with. So far I've not decided whether the rapid schema changes make me wish for separate business objects (so that server-side calculations need less refactoring, since all changes are restricted to the persistence layer) or for no separate business objects (because every change to the schema requires the business objects to change to stay in sync, even if the new sub-object or field is never used on the server except to pass verbatim to a client). So my question is whether it is sensible to store objects in the form they are usually going to be used, or if it's better to copy them into intermediate business objects to insulate both sides from each other (even when that isn't strictly necessary)? And I'd like to hear from anybody else who has had experience of a similar situation, perhaps choosing to persist XML or JSON instead of having an explicit schema which has to be assembled into a client format each time.

  • DDD: service contains two repository

    - by tikhop
    Does it correct way to have two repository inside one service and will it be an application or domain service? Suppose I have a Passenger object that should contains Passport (government id) object. I am getting Passenger from PassengerRepository. PassengerRepository create request to server and obtain data (json) than parse received data and store inside repository. I have confused because I want to store Passport as Entity and put it to PassportRepository but all information about password contains inside json than i received above. I guess that I should create a PassengerService that will be include PassengerRepository and PassportRepository with several methods like removePassport, addPassport, getAllPassenger and etc. UPDATE: So I guess that the better way is represent Passport as VO and store all passports inside Passenger aggregate. However there is another question: Where I should put the methods (methods calls server api) for management passenger's passport. I think the better place is so within Passenger aggregate.

  • puppet master --compile logs errors to stdout

    - by danny
    I see a bug about this that was accepted and then closed a year ago: http://projects.puppetlabs.com/issues/3670 but I'm using puppet 2.7.14 and am getting the same issue. I'm trying to use "puppet solo" (i.e. just running puppet apply on each server to be configured) as I only have 2 or 3 servers in this project and adding another server as a puppetmaster would be completely overkill. Unless I'm mistaken, the best way to apply a node manually to a server is to do: puppet master --compile=mynode > catalog.json puppet apply --catalog catalog.json But the puppet master command outputs a couple of warnings and notices to stdout, mixed in with the desired json content. And it uses colored output so I can't just pipe it through egrep -v '^warning:' EDIT: I guess it's not too big of a deal to use grep - since puppet 2.7 pretty-prints the actual content and the warnings don't ever start with spaces, piping the output through egrep '^( |{|})' works So my questions are basically: Is there a better way than this to apply a puppet node without using a puppetmaster? I can't really find any good references online to using puppet without a puppetmaster, even though that seems like a perfectly reasonable thing to do for a small project. Is there a setting or flag that I'm missing that will get puppet master to stop being an asshole and send its errors to stderr instead of stdout? Or do I really have to turn off color logging, then grep to exclude warning: and notice: lines?

  • How to set JS source directory in apache2?

    - by highBandWidth
    I am trying to run a very basic webserver for development/debugging. The static HTML seems to be delivered correctly, but it seems that the JavaScript libraries are not being delivered to the browser. The page HTML says something like <html> <head> <script type='text/javascript' src="/lib/json.js"></script> ... Now, I have set up a link for /lib/ in my httpd.conf as: Scriptalias /lib/ "/SomeFolder/lib/" When I do this, it can't fetch the files because this is what I see in my apache error log: ... [error] [client ::1] client denied by server configuration: /SomeFolder/lib/json.js, referer: http://localhost/SomeSite It seems that apache is not allowing access to the folder, so I add this to httpd.conf: Directory "/SomeFolder/lib/"> Allow from all </Directory> After this, browsing the page still does not run the JS, instead I see the following error in my apache error log: [error] [client ::1] (13)Permission denied: exec of '/SomeFolder/lib/json.js' failed, referer: http://localhost/SomeSite So now, it seems that apache is trying to run the JS files on the server like a cgi script or something. But I have not made that folder a cgi-bin folder. The only lines where SomeFolder is mentioned by name is in these lines in httpd.conf: Scriptalias /lib/ "/SomeFolder/lib/" Directory "/SomeFolder/lib/"> Allow from all </Directory>

  • How to have SSL on Amazon Elastic Load Balancer with a Gunicorn EC2 server?

    - by Riegie Godwin
    I'm a self taught back end engineer so I'm learning all of this stuff as I go along. For the longest time, I've been using basic authentication for my users. Many developers are advising against this approach since each request will contain the username & password in clear text. Anyone with the right skills can sniff on the connection between my iOS application and my Django/Gunicorn Server and obtain their password. I wouldn't want to put my user's credentials at risk so I would like to implement a more secure way of authentication. SSL seems to be the most viable option. My server doesn't serve any static content or anything crazy of that sort. All the server does is send and receive "json" responses from and to my iOS application. Here is my current topology. iOS application ------ Amazon Elastic Load Balancer ------- EC2 Instances running HTTP Gunicorn. Gunicorn runs on port 8000. I have a CNAME record from GoDaddy for the Amazon Elastic Load Balancer DNS. So instead of using the long DNS to make requests, I just use server.example.com. To interact with my servers I send and receive requests to server.example.com:8000/ This setup works and has been solid. However I need to have a more secure way. I would like to setup SSL between my iOS application and my Elastic Load Balancer. How can I go about doing this? Since I am only sending json responses to my application, do I really need to buy a certificate from a CA or can I create my own? (since browsers will not be interacting with my servers. My servers are only designed to send json responses to my iOS application).

  • How to replace the domain name in a Wordpress database?

    - by Cristian
    I have a Wordpress database which was installed in a development environment... thus, all references to the site itself have a fixed IP address (say 192.168.16.2). Now, I have to migrate that database to a new Wordpress installation on a hosting. The problem is that the SQL dump contains a lot of references to the IP address, and I have to replace it with: my_domain.com. I could use sed or some other command to change the that from the command line, the problem is that there are a lot of configuration data which uses JSON. So what? Well, as you know, JSON arrays uses things like: s:4: to know how many chars an element has, and thus, if I just replace the IP with the domain name, the configuration files will get corrupted. I used an app for Windows some years ago that allows to change values in a database and takes care of the JSON arrays. Unfortunately, I forgot the name of the app... so the question is: do you know any app that allows me to do what I want?

  • Selenium Webdriver (FirefoxDriver)

    - by Samareri
    Hey all, I'm using Selenium Webdriver to do some robottesting. Since some functions appear to only work in Firefox, I'm obligated to use Firefoxdriver. Now and then, something weird happens. Starting up te driver driver = new FirefoxDriver(); driver.get(URL); gets firefox to startup but not to go to the specified url. The strange thing is that it works on another computer with the same preferences set in Firefox. I solved this problem once by changing to another version of firefox, but this time this doesn't do the trick for me, it did however worked for the other developers. Yes, the error started for all developers on the same time, same day... My first question is: is it a firefox problem or Webdriver problem. Second question: how is it possible that it works on other pc's? Any help would be very appreciated Thanks Error: org.openqa.selenium.WebDriverException: Could not parse "".

  • Problem with Twitter basic authentication using AJAX

    - by jelford
    I'm developing a javascript App that needs, as part of its functionality, for users to be able to update their Twitter status. The App is designed to work on mobiles, and as such I don't really want to be sending users all the way over to the Twitter site to sign in; they should just be able to pass their credentials to the app, and I'll handle all the signin. So I'm trying to use the Basic Auth with the restful API. My code looks like: function postTweet(input){ $.ajax( { type: "POST", url: "http://twitter.com/statuses/update.json", data: {status: input}, dataType: "json", error: function() { alert("Some error occured"); }, success: function() { alert("Success!"); }, beforeSend: function(request) { request.setRequestHeader("Authorization", "Basic BASE64OFMYCREDENTIALS");} } ) ; } So, as far as I'm aware, this should perform the authentication from the XMLHttpRequest header, and then post the status. However, whenever I call this code, I get a "401 Unauthorized" error from Twitter. Below are the request & response headers from firebug: Request: OPTIONS /statuses/update.json HTTP/1.1 Host: twitter.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.9.2) Gecko/20100115 Firefox/3.6 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-gb,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Origin: null Access-Control-Request-Method: POST Access-Control-Request-Headers: authorization Response: HTTP/1.1 401 Unauthorized Date: Sat, 13 Mar 2010 11:08:58 GMT Server: hi Status: 401 Unauthorized WWW-Authenticate: Basic realm="Twitter API" X-Runtime: 0.00204 Content-Type: application/json; charset=utf-8 Cache-Control: no-cache, max-age=300 Set-Cookie: guest_id=1268478538488; path=/ _twitter_sess=BAh7CDoPY3JlYXRlZF9hdGwrCPlyNlcnAToHaWQiJWUyN2YzYjc3OTk2NGQ3%250ANzJkYTA4MjYzOWJmYTQyYmUyIgpmbGFzaElDOidBY3Rpb25Db250cm9sbGVy%250AOjpGbGFzaDo6Rmxhc2hIYXNoewAGOgpAdXNlZHsA--d687808459872da0aa6a89cab35fd347300b4d07; domain=.twitter.com; path=/ Expires: Sat, 13 Mar 2010 11:13:58 GMT Vary: Accept-Encoding Content-Encoding: gzip Content-Length: 88 Connection: close Any help with this would be much appreciated, Thanks, jelford ps.

    Dear fellow Programmers, I try to use the following google map webservice in order to locate greek addresses: http://maps.google.com/maps/api/geocode/json?address=??ad?µ?a? 16&sensor=false and it does not work. If I hit the same exactly address but written with latin alphabet characters: maps.google.com/maps/api/geocode/json?address=akadimias 16&sensor=false, it works and returns the right result. Could somebody help with this? (To use this service with greek letters as language parameter) Thank you in advance, Nicholas

  • IOS - Performance Issues with SVProgressHUD

    - by ScottOBot
    I have a section of code that is producing pour performance and not working as expected. it utilizes the SVProgressHUD from the following github repository at https://github.com/samvermette/SVProgressHUD. I have an area of code where I need to use [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]. I want to have a progress hud displayed before the synchronous request and then dismissed after the request has finished. Here is the code in question: //Display the progress HUB [SVProgressHUD showWithStatus:@"Signing Up..." maskType:SVProgressHUDMaskTypeClear]; NSError* error; NSURLResponse *response = nil; [self setUserCredentials]; // create json object for a users session NSDictionary* session = [NSDictionary dictionaryWithObjectsAndKeys: firstName, @"first_name", lastName, @"last_name", email, @"email", password, @"password", nil]; NSData *jsonSession = [NSJSONSerialization dataWithJSONObject:session options:NSJSONWritingPrettyPrinted error:&error]; NSString *url = [NSString stringWithFormat:@"%@api/v1/users.json", CoffeeURL]; NSURL *URL = [NSURL URLWithString:url]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:URL cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:30.0]; [request setHTTPMethod:@"POST"]; [request setValue:@"application/json" forHTTPHeaderField:@"Accept"]; [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; [request setValue:[NSString stringWithFormat:@"%d", [jsonSession length]] forHTTPHeaderField:@"Content-Length"]; [request setHTTPBody:jsonSession]; NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]; NSString *dataString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; NSDictionary *JSONResponse = [NSJSONSerialization JSONObjectWithData:[dataString dataUsingEncoding:NSUTF8StringEncoding] options:NSJSONReadingMutableContainers error:&error]; NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response; NSInteger statusCode = httpResponse.statusCode; NSLog(@"Status: %d", statusCode); if (JSONResponse != nil && statusCode == 200) { //Dismiss progress HUB here [SVProgressHUD dismiss]; return YES; } else { [SVProgressHUD dismiss]; return NO; } For some reason the synchronous request blocks the HUB from being displayed. It displays immediately after the synchronous request happens, unfortunatly this is also when it is dismissed. The behaviour displayed to the user is that the app hangs, waits for the synchronous request to finish, quickly flashes the HUB and then becomes responsive again. How can I fix this issue? I want the SVProgressHUB to be displayed during this hang time, how can I do this?

  • JIT: How to specify source/sink for arcs?

    I'm using JIT to render graphs. I'm using the RGraph feature. This JSON defines a graph: var json = [ { 'id': '1', 'name': 'CS 2110', 'adjacencies': ['0', '2'] }, { 'id': '1.5', 'name': 'INFO 2300', 'adjacencies': ['1'] }, { 'id': '0', 'name': 'CS 1110', 'adjacencies': ['1'] }, { 'id': '2', 'name': 'INFO 3300', 'adjacencies': ['1'] }, ] If I want a directed graph, how can I specify which nodes are sources and which are sinks?
