  • Issues with Sinatra and Heroku

    - by Brian Michel
    So I've created and published a Sinatra app to Heroku without any issues. I've even tested it locally with rackup to make sure it functions fine. There are a series of API calls to various places after a zip code is consumed from the URL, but Heroku just wants to tell me there is an server error. I've added an error page that tries to give me more description, however, it tells me it can't perform a `count' for #, which I assume means hash. Here's the code that I thin it's trying to execute... if weather_doc.root.elements["weather"].children.count > 1 curr_temp = weather_doc.root.elements["weather/current_conditions/temp_f"].attributes["data"] else raise error(404, "Not A Valid Zip Code!") end If anyone wants to bang on it, it can be reached at, http://quiet-journey-14.heroku.com/ , but there's not much to be had.

  • How can I measure distance with tastypie and geodjango?

    - by Twitch
    Using Tastypie and GeoDjango, I'm trying to return results of buildings located within 1 mile of a point. The TastyPie documentation states that distance lookups are not yet supported, but I am finding examples of people getting it work, such as this discussion and this discussion on StackOverflow, but no working code examples that can be applied. The idea that I am trying to work with is if I append a GET command to the end of a URL, then nearby locations are returned, for example: http://website.com/api/?format=json&building_point__distance_lte=[{"type": "Point", "coordinates": [153.09537, -27.52618]},{"type": "D", "m" : 1}] But when I try that, all I get back is: {"error": "Invalid resource lookup data provided (mismatched type)."} I've been pouring over the Tastypie document for days now and just can't figure out how to implement this. I'd provide more examples, but I know they'd be all terrible. All advice is appreciated, thank you!

  • Accessing loop iteration in a sub-function?

    - by DisgruntledGoat
    I'm using the Google Maps API to plot several points on a map. However, in the click event function below, i is always set to 4, i.e. its value after iterating the loop: // note these are actual addresses in the real page var addresses = new Array( "addr 1", "addr 2", "addr 3", "addr 4" ); for (var i = 0; i < addresses.length; i++) { geocoder.getLatLng(addresses[i], function(point) { if (point) { var marker = new GMarker(point); map.addOverlay(marker); map.setCenter(point, 13); GEvent.addListener(marker, "click", function() { // here, i=4 marker.openInfoWindowHtml("Address: <b>" + addresses[i] + "</b>"); }); } }); } So when the marker displays it's using addresses[4] which is undefined. How do I pass the correct value of i to the function?

  • Embedded analog of CouchDB, same as sqlite for SQL Server

    - by Mike Chaliy
    I like an idea of document oriented databases like CouchDB. I am looking for simple analog. My requirements is just: persistance storage for schema less data; some simple in-proc quering; good to have transactions and versioning; ruby API; map/reduce is aslo good to have; should work on shared hosting What I do not need is REST/HTTP interfaces (I will use it in-proc). Also I do not need all scalability stuff.

  • Drupal Views: Render Null Result for Relationship as 0

    - by Kyle S
    I have a View configured in Drupal to return nodes, sorting them by their average vote in descending order. For the purpose of the View, the value of the average votes is a Relationship. I noticed that nodes with no votes are displayed after nodes with a negative average. Nodes with no votes should have an average of 0, but I believe the MySQL JOIN is causing NULL values to be returned (as there are no matching rows in the joined table, since a row is created after the first vote is cast for that item). I discovered that with MySQL it is possible to output all values that are NULL in a column as another value with IFNULL(column_name,'other value'). I feel like I would need to modify the Views module in order to obtain this functionality, but I'm hoping that there is some sort of option that returns NULL values in a relation (a relation doesn't exist for the item) as 0 instead of NULL, so that I can properly sort the nodes. The modules I am using include Views, Voting API, Vote Up/Down, and CTools. Thanks.

  • How do I change the number of thumbnails seen in the Android sample Home application?

    - by Todd
    I am working with the sample Home application project on http://developer.android.com/resources/samples/Home/index.html I've added another value to the THUMBS_IDS and IMAGE_IDS Integer arrays in the Wallpaper class for a total of four wallpaper options. When I run the application with Device API version 7, Skin: HVGA, hw.lcd.density: 160, in portrait layout, the fourth wallpaper option is not shown. I need to use the directional keys in the emulator to see the 4th wallpaper option, because the first option is centered. I have modified only the wallpaper.xml file with a variety of android:layout_* options with no success at this point. How do I show all four of my wallpaper options?

  • C++ new line not translating

    - by m3n
    First off, I'm a complete beginner at C++. I'm coding something using an API, and would like to pass text containing new lines to it, and have it print out the new lines at the other end. If I hardcode whatever I want it to print out, like so printInApp("Hello\nWorld"); it does come out as separate lines in the other end, but if I retrieve the text from the app using a method that returns a const char then pass it straight to printInApp (which takes const char as argument), it comes out as a single line. Why's this and how would I go about to fix it?

  • Can I learn the iPhone SDK and complete an app by September?

    - by Kuro
    Hi everyone, I'm wondering if it's realistically possible to learn the iPhone SDK and complete an app by the end of this summer. The app shouldn't be too difficult, it would just interact with my site's API and essentially just fetch, create, and edit resources. I already have a little experience with the SDK (and I'm comfortable with Objective-C), so I'm not completely new to it. Although here I things I don't know how to do and what I'd need to learn: Log in to my site using basic http authentication and store the user's username/password for all future requests Implement a toolbar at the bottom to navigate between different views Fetch and parse xml into list items Do POST/PUT requests to create/edit a resource on my server Are there any good resources available to learn how to do those tasks above? Thanks!

  • C++11: thread_local or array of OpenCL 1.2 cl_kernel objects?

    - by user926918
    I need to run several C++11 threads (GCC 4.7.1) parallely in host. Each of them needs to use a device, say a GPU. As per OpenCL 1.2 spec (p. 357): All OpenCL API calls are thread-safe75 except clSetKernelArg. clSetKernelArg is safe to call from any host thread, and is safe to call re-entrantly so long as concurrent calls operate on different cl_kernel objects. However, the behavior of the cl_kernel object is undefined if clSetKernelArg is called from multiple host threads on the same cl_kernel object at the same time. An elegant way would be to use thread_local cl_kernel objects and the other way I can think of is to use an array of these objects such that i'th thread uses i'th object. As I have not implemented these earlier I was wondering if any of the two are good or are there better ways of getting things done. TIA, S

  • Android camera being landscaped in some devices

    - by nala4ever
    Im new to Android and I tried a tutorial for camera API. The tutorial works fine. When I use HTC desire I can see the camera view in both portrait and landscape, but when I use Samsung Galaxy I get a the camera view only in a landscaped view. I tried the following code to rotate the camera view as well.. Camera.Parameters parameters = camera.getParameters(); parameters.setRotation(90); then the camera doesn't work as expected. (screen splits into 4 and not clear). Does anyone have an idea for this issue ? Thanks.

  • Why Camera.setParameters(Camera.Parameters) does not work on Sony-Ericsson X10 and Droid?

    - by mobilekid
    Has anyone come across a strange behaviour with the Camera API when used on Sony-Ericsson X10 or Droid? For example the following code doesn't work on those devices. As a result I'm getting a lot of negative feedback on the Market translating into many cancelled orders... mParameters.set("rotation", orientation); mParameters.set("jpeg-quality", img_quality); mParameters.set("picture-size", "1024x768"); mCamera.setParameters(mParameters); Could you suggest an alternative way of achieving the same? Thanks.

  • Parse boolean values in strings for use with Function.apply

    - by as3cmdline
    I'm using String.split to parse a command line string into an array of strings. The result is then used to call a function using the Function.apply API. If apply(null, ["17"]) is called with this function: static function test(foo:int):void { trace(foo, typeof(foo)); } it works as expected (output: 17 number). However, calling apply(null, ["false"]) or apply(null, ["0"]) with this function: static function test(foo:Boolean):void { trace(foo, typeof(foo)); } does not work (expected output: false Boolean; actual output: true Boolean). Is there a way to make it recognize "true" and "false" (or anything else) as Boolean values, just like it does with numerical strings? Ideally "true" and "false" should also remain valid string values.

  • json call with C#

    - by Vaccano
    I am trying to make a json call using C#. I made a stab at creating a call, but it did not work: public bool SendAnSMSMessage(string message) { HttpWebRequest request = (HttpWebRequest) WebRequest.Create("http://api.pennysms.com/jsonrpc"); request.Method = "POST"; request.ContentType = "application/json"; string json = "{ \"method\": \"send\", "+ " \"params\": [ "+ " \"IPutAGuidHere\", "+ " \"[email protected]\", "+ " \"MyTenDigitNumberWasHere\", "+ " \""+message+"\" " + " ] "+ "}"; StreamWriter writer = new StreamWriter(request.GetRequestStream()); writer.Write(json); writer.Close(); return true; } Any advice on how to make this work would be appreciated.

  • do people value information or aesthetic value of websites ? [closed]

    - by fwfwfw
    I'm thinking, why does the web have to be so colorful. meaning, all the information is buried deep beneath layers of flash, javascripts, html and images. Sure, a good positioning of these media files, create an aesthetic value but how important is it to the user ? moreover, aren't people looking for information after all ? why can't the internet be a uniform looking data warehouse ? now we've gotta digg through all the aesthetic junk, using shady web scraping techniques, unless RSS or API is provided. why can't we settle for just a dull grey button and framesets for navigation ? why can't all sites have navigation frame on the left and top ? why can't all sites put their damn data always in normalized table tag ?

  • MSDN Remark regards Security Descriptors

    - by Doori Bar
    I'm trying to extract and restore a Security Descriptor of a NTFS file, via Windows API - XP SP3, I'm trying to understand which functions are actually able to do it properly, but I simply fail. I found this Remark over MSDN: http://msdn.microsoft.com/en-us/library/aa379573%28VS.85%29.aspx "Some SECURITY_INFORMATION members work only with the SetNamedSecurityInfo function. These members are not returned in the structure returned by other security functions such as GetNamedSecurityInfo..." "Some members..." Which members? Why? "Other Security functions such as..." Which functions? Why? Anybody have any experience with extracting and restoring a security descriptor of a NTFS file? Thanks in advance, Doori Bar

  • mature, powerful Perl library to support text/string operation ?

    - by user534009
    Do we have a mature, powerful Perl library to support text/string operation ? for example, if I need to trim a string, I need to write a function like below. Then question is, do we have an existing API so that I can import and call it ? just like StringUtils.trim(s) in Apache Common Lang. Thanks. sub trim($) { my $string = shift; $string =~ s/^\s+//; $string =~ s/\s+$//; return $string; }

  • On which Windows versions and configurations does my C++ app run?

    - by saas
    I've built a C++ application using MSVC 2010, default compile settings (note: Using "Multithreaded" instead of "Multithreaded DLL" to avoid the Microsoft C++ runtime being needed). I used only the STL and a few, old functions from the Win32 API (Windows.h). Where will my app run? (98-7?) Can the be any differences on how my app works on different PCs? As said: It's only a simple console app. I'd be glad if you could add some additional information if you have it!

  • Android app using 2.x APIs that will also run on 1.x

    - by Adam Haile
    I'm working on an Android app in which I would like to use multi-touch. However, I do not want to completely leave out those still running a 1.x OS phone. How do you program the app so that you can use the 2.x multi-touch APIs (or any other higher level API for that matter) and still allow it to gracefully degrade on 1.x systems. If you create a project in Eclipse for 1.x can you even still access the 2.x APIs? Basically I want it to show up in the marketplace and work on all 1.6 and higher phones and just allow access to the higher level functionality if available. Also, if anyone can point me to any data on the number of 1.x devices vs. 2.x devices in use, it would be greatly appreciated.

  • How to update (append to) an href in jquery?

    - by John Isaacks
    I have a list of links that all go to a google maps api. the links already have the daddr (destination) parameter in them as static. I am using Geo-Location to find the users position and I want to add the saddr (source address) to the links once I get the data. so basically I will need to add something like &saddr=50.1234567,-50.03452 at the tail end of all the links pointing to google maps All the links have a class called directions-link and from this page I have figured out how to change them: $("a.directions-link").attr("href", "http://www.google.com/"); However I only want to append my value to the end of the href without changing what the href already is. How can I do that? Thanks!!

    As the jQuery API is currently down, is anyone able to assist me with the below? I am ajax loading an unordered list into the web page and need to be able to attach hover and click events to the list items. <ul> <li class="option">Item 1</li> <li class="option">Item 1</li> <li class="option">Item 1</li> </ul> So far I have tried a few variations of the below jQuery code using .on for version 1.7+ $("ul").on("click", "li .option", function(){ alert($(this).text()); }); Can anyone point me in the right direction? I'm aware that .live has been depreciated and that .delegate has been superceeded so really only looking for a solution that will allow me to use .on. Thanks as always!

  • Preserve trailing whitespace Sybase

    - by AngryWhenHungry
    I have a big chunk of textual data which I split and write multiple rows of a varchar(255) column of a table. Sometimes, the last character happens to be a space. When I read back this row, the trailing space is chopped and I get only 254 characters. This messes up my data when I append the next row to the end of this one. My code sends the full 255 char (incl space) to the DB API. How can I check that the trailing space is actually written to the table? I am not in a position to rewrite/redesign legacy code. Is there any setting - either in the DB, DB interface, read/write calls etc - that I can use to preserve the trailing space?

  • How can I convert (string) timestamp to mysql datetime on Windows 32 bit PHP?

    - by user239619
    I'm attempting to call LinkedIn's API and store Network Updates. Each update has a Unix timestamp that I'm retrieving as a string variable from the REST XML response. I want to convert the string timestamp to a mysql datetime format. The date() function accepts an integer as the second argument for time to be converted. However, I'm on Windows 32 bit PHP and the integer type for this platform is limited to 2147483647. $timestamp = '1293714626675'; // sample pulled from linkedin $timestamp = (int) $timestamp; // timestamp now equals 2147483647 $mysqlDatetime = date('Y-m-d H:i:s', $timestamp); // produces incorrect time Is there a better method of creating the mysql datetime in PHP? I realize that I can convert it upon insert into MySQL however, that would require changing other dependent code.
