  • About the fix for the interference between Company mode and Yasnippet

    - by janoChen
    Emacs wiki says: Company does interfere with Yasnippet’s native behaviour. Here’s a quick fix: http://gist.github.com/265010 The code is the following: (define-key company-active-map "\t" 'company-yasnippet-or-completion) (defun company-yasnippet-or-completion () (interactive) (if (yas/expansion-at-point) (progn (company-abort) (yas/expand)) (company-complete-common))) (defun yas/expansion-at-point () "Tested with v0.6.1. Extracted from `yas/expand-1'" (first (yas/current-key))) I placed that code in my .emacs and the following message appeared: Warning (initialization): An error occurred while loading `c:/Documents and Settings/Alex.AUTOINSTALL.001/Application Data/.emacs.elc': Symbol's value as variable is void: company-active-map To ensure normal operation, you should investigate and remove the cause of the error in your initialization file. Start Emacs with the `--debug-init' option to view a complete error backtrace. Do I have to place the fix code inside a YASnippet's .el file? or in my .emacs (which throws me an error)?

  • How can I create a collection of references in C#

    - by Jonathan Kaufman
    Ok I am having a cross language hiccup. In C# with it's great collections like List and I have: a Map class with properties of: List<byte[]> Images; List<Tile> Tiles; a Tile Class of: byte[] ImageData; int X; int Y; Now I want to add an image to the Map class and have the ImageData property of the Tile Classes to "reference" it. I have discovered I can't just assign it Images[0]. You can't have a reference to an object of a List. My fix was to create a Dictionary. Is this the best way or can I somehow have a "pointer" to a collection of objects?

  • dijit/form/Select broken in Internet Explorer using Esri Javascript 3.7

    - by disuse
    After developing a web map app in Firefox, I tested my code in Internet Explorer (company standard) to discover that the dijit/form/Select is misbehaving using the latest Esri JavaScript v3.7. The issue I am seeing is that the Select will not update/change from the first option in the list when using v3.7. If I bump the version down to 3.6, it works as expected. I've tried IE browser modes from 7 to 10 and am experiencing the same behavior between all of them. Can someone confirm they are experiencing the same thing? Example in 3.7 - http://jsbin.com/aVIsApO/1/edit Example in 3.6 - http://jsbin.com/odIxETu/7/edit Codeblock var url = "http://services.arcgis.com/V6ZHFr6zdgNZuVG0/ArcGIS/rest/services/Street_Trees/FeatureServer/0"; var frmTrees; require([ "esri/tasks/query", "esri/tasks/QueryTask", "dojo/dom-construct", "dijit/form/Select", "dojo/parser", "dijit/registry", "dojo/on", "dojo/ready", "dojo/_base/connect", "dojo/domReady!" ], function( Query, QueryTask, domConstruct, Select, parser, registry, on, ready, connect ) { ready(function() { frmTrees = registry.byId("trees"); var qt = new QueryTask(url); var query = new Query(); query.where = "FID < 25"; query.orderByFields = ["qSpecies"]; query.returnGeometry = false; query.outFields = ["qSpecies", "TreeID"]; query.groupByFieldsForStatistics = ["qSpecies"]; //query.returnDistinctValues = true; qt.execute(query, function(results) { //var frm_domain_area = dom.byId("domain_area"); var testVals = {}; for (var i = 0; i < results.features.length; i++) { var id = results.features[i].attributes.TreeID; var desc = results.features[i].attributes.qSpecies; if (!testVals[id]) { testVals[id] = true; var selectElem = domConstruct.create("option",{ label: desc + " (" + id + ")", value: id }); frmTrees.addOption(selectElem); } } }); frmTrees.on("change", function() { console.debug(frmTrees.get("value")); }); }); });

  • reversing keys/values - create new instance of HashMap

    - by stck777
    I’ve got an existing instance of HashMap simply called sale (it is Map) I use it to log customers and items history. Is there a way to create a new instance of HashMap, that effectively reverses this usage? i.e will show each item purchased as a unique key and the corresponding value as a String set of the customers that have purchased that product. I suspect there is a simple process using keySet() in some way to iterate over the sales map but I just can’t see how to do this. Any help would be much appreciated.

  • Does anyone know why my maps only show grid

    - by NickTFried
    I've doubled checked my API key is right and that is right I doubled checked that it was correct. Here is my source and XML could anyone check to see what is wrong.

  • Gradients and memory

    - by user146780
    I'm creating a drawing application with OpenGL. I'v created an algorithm that generates gradient textures. I then map these to my polygons and this works quite well. What I realized is how much memory this requires. Creating 1000 gradients takes about 800MB and that's way too much. Is there an alternative to textures, or a way to compress them, or another way to map gradients to polygons that doesn't use up as much memory? Thanks My polygons are concave, I use GLUTesselator, and they are multicolored and point to point

  • Triangular bounding volumes

    - by Cheery
    I've come up with an alternative for beziers that might be easier to ray-trace, perhaps even though a plain vertex shader. Though there's missing a piece. I need to find the parametric surface equation from the surface normals I have for edge vertices. I also have to know it's peak and valley so I can constraint the depth of my bounding triangle. Image explains the overall idea: I build a bounding-volume from a control triangle. Then apply a function to each parametric coordinate of the triangle (s+t+u=1 where s,t,u = 0) to get the height coordinate for that certain point. Simply put, it produces a procedurally generated height-map for the triangle's surface. I just need to find a function that generates the height-map so I can make it work.

  • JSF 2.0: Preserving component state across multiple views

    - by tlind
    The web application I am developing using MyFaces 2.0.3 / PrimeFaces 2.2RC2 is divided into a content and a navigation area. In the navigation area, which is included into multiple pages using templating (i.e. <ui:define>), there are some widgets (e.g. a navigation tree, collapsible panels etc.) of which I want to preserve the component state across views. For example, let's say I am on the home page. When I navigate to a product details page by clicking on a product in the navigation tree, my Java code triggers a redirect using navigationHandler.handleNavigation(context, null, "/detailspage.jsf?faces-redirect=true") Another way of getting to that details page would be by directly clicking on a product teaser that is shown on the home page. The corresponding <h:link> would lead us to the details page. In both cases, the expansion state of my navigation tree (a PrimeFaces tree component) and my collapsible panels is lost. I understand this is because the redirect / h:link results in the creation of a new view. What is the best way of dealing with this? I am already using MyFaces Orchestra in my project along with its conversation scope, but I am not sure if this is of any help here (since I'd have to bind the expansion/collapsed state of the widgets to a backing bean... but as far as I know, this is not possible). Is there a way of telling JSF which component states to propagate to the next view, assuming that the same component exists in that view? I guess I could need a pointer into the right direction here. Thanks! Update 1: I just tried binding the panels and the tree to a session-scoped bean, but this seems to have no effect. Also, I guess I would have to bind all child components (if any) manually, so this doesn't seem like the way to go. Update 2: Binding UI components to non-request scoped beans is not a good idea (see link I posted in a comment below). If there is no easier approach, I might have to proceed as follows: When a panel is collapsed or the tree is expanded, save the current state in a session-scoped backing bean (!= the UI component itself) The components' states are stored in a map. The map key is the component's (hopefully) unique, relative ID. I cannot use the whole absolute component path here, since the IDs of the parent naming containers might change if the view changes, assuming these IDs are generated programmatically. As soon as a new view gets constructed, retrieve the components' states from the map and apply them to the components. For example, in case of the panels, I can set the collapsed attribute to a value retrieved from my session-scoped backing bean.

  • Adding RESTful route to Rails app

    - by macek
    I'm reading these two pages resources Adding more RESTful actions The Rails Guides page shows map.resources :photos, :new => { :upload => :post } And its corresponding URL /photos/upload This looks wonderful. My routes.rb shows this map.resources :users, :new => { :signup => :get, :register => :post } When I do: [~/my_app]$ rake routes I see the two new routes added signup_new_user GET /users/new/signup(.:format) register_new_user POST /users/new/register(.:format) Note the inclusion of /new! I don't want that. I just want /users/signup and /users/register (as described in the Rails Routing Guide). Any help?

  • iframe height not taken into account by IE8

    - by Pedro
    Hi guys, I'm building a dummy widget for a iGoogle/Netvibes like portal. This is a "Google Maps" widget, as it only renders a map centered on a specific location. The widget looks good in all browsers but IE8, in which the height I specify to the <div> that contains the map is not taken into account. Here's the interesting part of the code: <body onload="initialize()" > <div id="map_canvas" style="height:400px; width: 100%;"></div> </body> I have no control on the portal, so the only thing I can modify is the widget itself. I also tried to set the height for the <body>, but same thing. Any idea on why it's not working in IE? Thanks!

  • Subdomain mapping to another external subdomain

    - by Davorin
    I'm trying to map help.domain1.com to help.domain2.com. I've seen this on UserVoice. They let you map something.yourdomain.com to something.uservoice.com. On domain1.com I've set up a CNAME to help.domain2.com. It works fine but when I open help.domain1.com I get the content of domain2.com instead of help.domain2.com. After some experimenting I've realized that this is an expected behavior. So my question is what do I have to do on domain2.com (or maybe on domain1.com?) to have it show content of subdomain "help.domain2.com" when I navigate help.domain1.com? (I'm using Plesk and the OS is Windows Server 2003)

  • identify accounts using zend-openid [HELP]

  • Strange problem when converting RGB to HSV

    - by zaplec
    Hi, I made a small RGB to HSV converter algorithm with C. It seems to work pretty well, but there is one strange problem: If I first convert i.e. a 800x600 picture into HSV map and then back to RGB map without doing any changes in the values, I get some pixels that are convertet incorrectly. Then if I try to convert those misbehaving single pixels alone to and back, they're converted correctly. Any idea what could be the problem? I'm using Daniel Karlings PNGLite to open that PNG file. Here are the source code of my main.c, rgbtohsv.c and rgbtohsv.h rgbToHsv.h rgbToHsv.c pngmain.c I linked pngmain only that if somebody wants to test and run this on his own system. -zaplec

  • No pre-built ActionBar for Android pre-3.0?

    - by Ollie C
    I note the release a few days ago of the static library bringing fragments to Android versions prior to 3.0, but does this library include the ActionBar? I suspect not. I assume that for an app that will work on pre-3.0 versions, that it needs a hand-built ActionBar implementation for versions up to 2.3 and then to use the OS default ActionBar in v3.0? for some reason I assumed the library had ActionBar in it, but as I dig further I'm not finding any evidence of its presence.

  • Vim open file under cursor

    - by ereOn
    Hi, Let's say I have the following file tree: / include/ library/ a.hpp b.hpp src/ a.cpp b.cpp And the following /src/a.cpp file: #include "a.hpp" #include "b.hpp" I always open Vim at the root directory. So when I want to load a.hpp I do : :tabnew include/library/a.hpp or: :tabnew **/a.hpp I'd like to map <F4> to open the file under the cursor in a new tab, using a recursive search. I tried the following mapping command: :map <F4> :tabnew **/expand("<cfile>")<cr> But obviously, this can't work, as it tries to open the file "/expand(" instead. Any clue on how I could do that ? Thanks.

  • 503 server response for Googlebot

    - by Hallik
    I put an .htaccess file in my webroot with the following contents RewriteBase / RewriteCond %{HTTP_USER_AGENT} ^.*(Googlebot|Googlebot|Mediapartners|Adsbot|Feedfetcher)-?(Google|Image)? [NC] RewriteRule .* /var/www/503.html This website is in maintenance mode, and I don't want anything indexed yet. I tested the code with a firefox User-Agent switcher plugin, and looking at the access log it shows this at the end of each log entry, but watching in TamperData or Firebug, it still returns a 200 server response instead of a 503. What am I doing wrong? "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)" contents of /var/www/503.html <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 3.2//EN"> <html> <head> <title>503 - Service temporary unavailable</title> </head> <body> <h1>503 - Service temporary unavailable</h1> <p>Sorry, this website is currently down for maintainance please retry later</p> </body> </html> I get this in my error log. LogLevel debug, would that go into the vhost in a specific place? Every answer I see on google is something different. Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.

  • Release an object without a pointer?

    - by Kai Friis
    I’ve just started developing for iPhone and am trying to get my head around memory management. I made a small program that shows a map and an annotation on the map. For the annotation I made a simple class that implements the MKAnnotation protocol. To create and add the annotation I wrote this: [self.myMapView addAnnotation:[[MyAnnotation alloc] init]]; It worked fine until I tried to release the object. Nothing to release. This is what I would have done in C#, I guess it doesn’t work without garbage collection? So is this the only way to do it? MyAnnotation *myAnnotation = [[MyAnnotation alloc] init]; [self.myMapView addAnnotation: myAnnotation]; [myAnnotation release];

  • Problem with Clojure function

    - by Bozhidar Batsov
    Hi, everyone, I've started working yesterday on the Euler Project in Clojure and I have a problem with one of my solutions I cannot figure out. I have this function: (defn find-max-palindrom-in-range [beg end] (reduce max (loop [n beg result []] (if (>= n end) result (recur (inc n) (concat result (filter #(is-palindrom? %) (map #(* n %) (range beg end))))))))) I try to run it like this: (find-max-palindrom-in-range 100 1000) and I get this exception: java.lang.Integer cannot be cast to clojure.lang.IFn [Thrown class java.lang.ClassCastException] which I presume means that at some place I'm trying to evaluate an Integer as a function. I however cannot find this place and what puzzles me more is that everything works if I simply evaluate it like this: (reduce max (loop [n 100 result []] (if (>= n 1000) result (recur (inc n) (concat result (filter #(is-palindrom? %) (map #(* n %) (range 100 1000)))))))) (I've just stripped down the function definition and replaced the parameters with constants) Thanks in advance for your help and sorry that I probably bother you with idiotic mistake on my part. Btw I'm using Clojure 1.1 and the newest SLIME from ELPA.

  • Pass errors in Django using HttpResponseRedirect

    - by JPC
    I know that HttpResponseRedirect only takes one parameter, a URL. But there are cases when I want to redirect with an error message to display. I was reading this post: How to pass information using an http redirect (in Django) and there were a lot of good suggestions. I don't really want to use a library that I don't know how works. I don't want to rely on messages which, according to the Django docs, is going to be removed. I thought about using sessions. I also like the idea of passing it in a URL, something like: return HttpResponseRedirect('/someurl/?error=1') and then having some map from error code to message. Is it good practice to have a global map-like structure which hard codes in these error messages or is there a better way? Or should I just use a session EDIT: I got it working using a session. Is that a good practice to put things like this in the session?

The problem is that I want to map my project to a certain place in my website. ie. In my Eclipse PHP project I have a folder called com I want this to map to /com in the webstie. I tried to do this in the mapping section of the Eclipse server setup but it didn't work. When I type http://localhost/com/ It should go to my project folder, however, when I type other folder it should use the normal website folders. how can I do this?
