• Interacting with RESTful API's via Javascript?

  - by Alex

  Hi there, to start off, I know C++, C#, Python, some Ruby, and basic Javascript. Anyway, my question revolves around how to interact with RESTful API's via Javascript. I haven't been able to find any good examples on various websites, and so I've come here. So my basic question is: How do I interact with RESTful API's via JS? And where can I find out how to implement OAuth in JS? I know how to get my keys and such, just not how to actually code them in. Below is an example of a twitter API status update run from my MAC terminal with curl: curl -u username:password -d "my tweet" http://api.twitter.com/1/statuses/update.json How can I implement this in Javascript (preferably with OAuth authentication)? This would at least start me going in the right direction. Thanks so much!!

• Puppet Directory and File ownership ignored

• CoffeeScript Class Properties Within Nested Anonymous Functions

  - by Aric

  I'm just taking a look at CoffeeScript for the first time so bare with me if this is a dumb question. I'm familiar with the hidden pattern methodology however I'm still wrapping my head around object prototypes. I'm trying to create a basic class for controlling a section on my site. The problem I'm running into is losing defined class variables within a different scope. For example, the code below works fine and creates the properties within the object perfectly. However when I jump into a jQuery callback I lose all knowledge of the class variables storing some of the jQuery objects for multiple uses. Is there a way to grab them from within the callback function? class Session initBinds: -> @loginForm.bind 'ajax:success', (data, status, xhr) -> console.log("processed") return @loginForm.bind 'ajax:before', (xhr, settings) -> console.log @loader // need access to Session.loader return return init: -> @loginForm = $("form#login-form") @loader = $("img#login-loader") this.initBinds() return

• Rx: Piecing together multiple IObservable web requests

  - by McLovin

  Hello, I'm creating multiple asynchronous web requests using IObservables and reactive extensions. So this creates observable for "GET" web request: var tweetObservalue = from request in WebRequestExtensions.CreateWebRequest(outUrl + querystring, method) from response in request.GetResponseAsync() let responseStream = response.GetResponseStream() let reader = new StreamReader(responseStream) select reader.ReadToEnd(); And I can do tweetObservable.Subscribe(response => dosomethingwithresponse(response)); What is the correct way of executing multiple asynchronous web requests with IObservables and LINQ that have to wait until other requests have been finished? For example first I would like to verify user info: create userInfoObservable, then if user info is correct I want to update stats so I get updateStatusObservable then if status is updated I would like create friendshipObservable and so on. Also bonus question, there is a case where I would like to execute web calls simultaneously and when all are finished execute another observable which will until other calls are finished. Thank you.

• effective retrieve for a voting system in PHP and MySQL

  - by Adnan

  Hello, I have a system where registered users can vote up/vote down comment for a picture. Something very similar to SO's voting system. I store the votes in a table with values as such; vote_id | vote_comment_id | vote_user_id | vote_date | vote_type Now I have few a question concerned the speed and efficiency for the following; PROB: Once a user opens the picture page with comments I need, if that user has already voted UP/DOWN a comment to show it like; "you voted up" or "you voted down" next to the comment (in SO it the vote image is highlighted) MY POSSIBLE SOL: Right now when I open a picture page for each comment I loop thru, I loop thru my table of votes as well and check if a user has voted and show the status (I compare the vote_user_id with the user's session). How efficient is this? Anyone have a better approach to tackle this kind of problem?

• USB enumeration failure in ColdFire MCF52259

  - by Quicksilver

  Anybody with programming experience on the ColdFire line, please help! I'm using the CMX USB-Lite stack with the ColdFire MCF52259. For some reason, USB enumeration fails at the very first step, as soon as I enable the DP pull-up resistor. This is what I'm doing :- INT_ENB, OTG_INT_EN, ERR_ENB are set to 0x0 INT_STAT, OTG_INT_STAT and ERR_STAT are set to 0xff (This should clear all interrupts) In the Interrupt Status Register, bits 0 (Mask All) and 53 are made 0, all others are 1. TOK_DNE, USB_RST and STALL interrupts are enabled in INT_ENB. BDT base address is set. MCF_USB_CTL holds 0x1 PROBLEM: After the host issues the first reset (at which point I enable Control endpoint 0), instead of the expected Get Descriptor request I'm getting an endless series of resets. At least, that's what it looks like, because the TOK_DNE interrupt never triggers. Is there anything I'm doing wrong?

• Cocoa NSStatusBar Global HotKey

  - by Craig

  I have created an NSStatusBar cocoa application which sits in the system status bar. I want to assign a hotkey so that when pressed it toggles my applications and show the menu. Is this possible?, In my searching and experimenting I have found a few different ways of assigning global hot keys that can be pressed when your application is in the background but I can't find any way to problematically make the menu show. Is this possible?, If anyone thinks a way of assigning a global hotkey is best please post it. Thanks. One of the hotkey tutorials I found was on http://dbachrach.com/blog/2005/11/program-global-hotkeys-in-cocoa-easily/ for anyone interested.

• Flash video hiding the cursor on Mac OS X

  - by Tibor

  I found a Core Graphics function, CGCursorIsVisible, that one can use to determine whether the mouse cursor is shown on screen. I have a small app that uses a timer to call that function a few times a second to see if the cursor is shown or hidden (as I found no way to get my app notified when the mouse cursor shown/hidden status changes). The above works correctly except… when the Flash browser plugin plays a video: the mouse cursor gets hidden after a few seconds of mouse inactivity but CGCursorIsVisible() still keeps telling me that the cursor is indeed shown as if nothing happened. What I need is to be able to tell, at any given moment, whether the mouse cursor is shown to the end user on any screen. Is there any way to do that even in the case of playing a video using the Flash plugin?

• Mibble MIB Parser - extracting comments from the mib.

  - by this.matt

  I am using the Mibble MIB Parser to extract all simple data types from an MIB file. I've been successful until my attempt to extract comment text. Take the following module as an example: invBookList OBJECT-TYPE SYNTAX INTEGER { mobydick(1), -- call me ishmael paradiselost(2), -- aComment 1984(3), -- aComment solaris(4) -- aComment } MAX-ACCESS read-only STATUS current DESCRIPTION "A few Books for an example." ::= { invMasterList 43 } According to Mibble's API, the OBJECT-TYPE can be accessed by extracting an SnmpObjectType and then calling the appropriate getter method. Which I have done, and can successfully extract all of the text except the comments in the INTEGER syntax. I have tried calling getSyntax().getComment() on the SnmpObjectType, but always returns null. getSyntax() will extract the INTEGER syntax, e.g.: mobydick(1),paradiselist(2),1984(3),solaris(4) but unfortunately strips out the comments. Any one out there have experience with Mibble Parser who knows how to extract the comments? Many Thanks.

• Can a program that controls IE detect if a HTTP 30x code is encountered?

  - by hillu

  I am trying to control an InternetExplorer.Application via the COM interface, using Perl, Win32::OLE, and information from MSDN. My goal is to get as good an idea as possible about what IE is doing. (Related to this question.) IE uses events to notify my program when it has finished various stages of processing a certain URL (NavigateComplete2, DownloadComplete DocumentComplete). It can also tell my program about various errors it encounters (NavigateError2). I consider that part of my problem solved well enough. I would also like to be able to reliably detect if IE is redirected by the server. Primarily, I'm concerned about HTTP 30x status codes. Is there a way to do this, either with COM automation or via another route?

• Is using value converters to generate GUI-friendly strings a misuse of value converters?

  - by tempy

  Currently, I use value converters to generate user-friendly strings for the GUI. As an example, I have a window that displays the number of available entities in the status bar. The Viewmodel simply has an int dependency property that the calling code can set, and then on the binding for the textbox that displays the number of entities, I specify the int dependency property and a value converter that changes "x" into "x entities available". My code is starting to become littered with these converters, and I have a large number of annoying resource declarations in my XAML, and yet I like them because all the GUI-specific string formatting is being isolated in the converters and the calling code doesn't have to worry about it. But still, I wonder if this is not the purpose that value converters were made for.

• Best Practices of fault toleration and reliability for scheduled tasks or services

  - by user177883

  I have been working on many applications which run as windows service or scheduled tasks. Now, i want to make sure that these applications will be fault tolerant and reliable. For example; i have a service that runs every hour. if the service crashes while its operating or running, i d like the application to run again for the same period, to avoid data loss. moreover, i d like the program to report the error with details. My goal is to avoid data loss and not falling behind for running the program. I have built a class library that a user can import into a project. Library is supposed to keep information of running instance of the program, ie. program reads and writes information of running interval, running status etc. This data is stored in a database. I was curious, if there are some best practices to make the scheduled tasks/ windows services fault tolerant and reliable.

• How to verify an XML digital signature in Cocoa?

  - by Geoff Smith

  I have a C# application that uses XML digital signatures to sign license files. I've used the standard Microsoft approach described here. I'm porting the application to the MAC and need to verify the signature. My general question is how best to do this? This is what I've done: I've used macport to install Aleksey's xmlsec1 library. Used the Chilkat library to convert my XML public key to a PEM file Chilkat.PublicKey pubKey = new Chilkat.PublicKey(); pubKey.LoadXml(publicKeyXml); pubKey.SaveOpenSslPemFile("publicKey.pem"); Compiled and ran the alekseys sample program. See (http://www.aleksey.com/xmlsec/api/xmlsec-verify-with-key.html) to verify an XML dsig. Result: my license files fail to validate. The call to xmlSecDSigCtxVerify fails with status=unknown. Now for my specific question: What can I do next? Geoff

• Explore a COM Object in PHP

  - by shaiss

  What would be the proper way to explode a COM object for debugging? I have a 3rd party function that returns a multilevel object. The documentation is non existant, so I'd like to be able to echo everything out of the object or debug it in Komodo IDE. Komodo just says Object and nothing else. Maybe convert to array? I know some of the existing options such as $com->Status, but there are more variables returned that I'd like to know what they are.

• Visual Web Developer 2005 Express loads very slowly

  - by d03boy

  I admit that I am not a guru of Visual Studio products at all. I am using Visual Web Developer 2005 Express Edition and I'm trying to load someone else's project. This project happens to be a website with many pages. After loading VWD, it asks for a project to open and I select the solution file. It then proceeds to take an extremely long time to load. The status bar indicates that references are being loaded, many of which are in the System.Web.* area it seems. It seems like it's going back and forth between some different packages. The loading time is upwards of 20 to 30 minutes or more. Some others have stated that their projects open fine when they go to File Open Website... and choose the project directory from there. Any ideas what the problem could be and how to fix it? Edit: It finally completed loading after an hour approximately.

• HTML5 Cache manifest file itself is not cached, and called at each resource load

  - by Mic

  We have a web app that runs on the iPhone.The manifest file is ok, and the resources(html, css, js) are cached correctly.The page sits in the home screen. The trouble is, when the page loads a resource from the cache, there is as well a GET call to the server to read the Cache Manifest file.The server is configured to send the correct header (max-age=31536000; public, etc...) and caches well all other files except the cache manifest itself. Is this a normal behavior? It looks there is a slight lag, because of that call, for each resource load.Any idea, if these multiple calls can get a status 304 or even better avoided?

• How to build sqlite for Python 2.4?

  - by Verrtex

  I would like to use pysqlite interface between Python and sdlite database. I have already Python and SQLite on my computer. But I have troubles with installation of pysqlite. During the installation I get the following error message: error: command 'gcc' failed with exit status 1 As far as I understood the problems appears because version of my Python is 2.4.3 and SQLite is integrated in Python since 2.5. However, I also found out that it IS possible to build sqlite for Python 2.4 (using some tricks, probably). Does anybody know how to build sqlite for Python 2.4? As another option I could try to install higher version of Python. However I do not have root privileges. Does anybody know what will be the easiest way to solve the problem (build SQLite fro Python 2.4, or install newer version of Python)? I have to mention that I would not like to overwrite the old version version of Python. Thank you in advance.

  Would it be possible to use the Office 2010 web apps with an ASP.NET application? For example: - For each user of my ASP.NET application there is a folder with Word documents on my server - The ASP.NET application displays the available documents in a grid to the user - When clicking on one of the documents in the grid, the Word document is loaded in an IFrame which contains the Office 2010 web apps Word interface and editing of the document can take place - After editing, the document can be saved to the server, and the ASP.NET grid displays an updated status Would such a scenario be possible? And what do you need, e.g. Sharepoint, Office 2010 licenses?

• jQuery event.stopPropagation is not working on <a>

  - by HorusKol

  I have the following javascript: $('#ge-display').click(function (event) { window.open('/googleearth/ge-display.php','','scrollbars=yes,menubar=no,height=650,width=1000,resizable=yes,toolbar=yes,location=no,status=no'); event.stopPropagation(); return false; }); the element with id 'ge-display' is a standard link: <a href="/googleearth/ge-display.php" id="ge-display" target="_blank">Load Google Earth Plugin (in a new window)</a> The problem is - when I take out the 'return false;' line from the click event handler, the javascript popup opens, and then another browser window opens - I thought stopPropagation() would prevent the links own click handler? I've also tried stopImmediatePropagation() - but I still need to return false to stop the default behaviour of the link.

• Jquery AJAX and figuring out how NOT to nest callbacks for multiple reloads.

  - by David H

  I have a site with a few containers that need to load content dynamically via AJAX. Most of the links inside of the containers actually load new data in that same container. I.E: $("#navmenu_item1").click(function() { $("#navmenu").load(blah); }); When I click on a link, lets say "logout," and the menu reloads with the updated login status, none of the links now work because I would need to add a new .click into the callback code. Now with repeated clicks and AJAX requests I am not sure how to move forward from here, as I am sure nested callbacks are not optimal. What would be the best way to do this? Do I include the .click event inside the actual AJAX file being pulled from the server, instead of within index.php? Or can I somehow reload the DOM? Thanks for the help!
