• const return value and template instantiation

  - by Rimo

  From Herb Sutter's GotW #6 Return-by-value should normally be const for non-builtin return types. .... Note: Lakos (pg. 618) argues against returning const value, and notes that it is redundant for builtins anyway (for example, returning "const int"), which he notes may interfere with template instantiation. .... While Sutter seems to disagree on whether to return a const value or non-const value when returning an object of a non-built type by value with Lakos, he generally agrees that returning a const value of a built-in type (e.g const int) is not a good idea. While I understand why that is useless because the return value cannot be modified as it is an rvalue, I cannot find an example of how that might interfere with template instantiation. Please give me an example of how having a const qualifier for a return type might interfere with template instantiation.

• jQuery Highlight Radio Labels Only

  - by Michael

  I'm trying to use jQuery validation to highlight the labels for my radio buttons only, and not the labels for my other inputs. I have a label for my radio button set called 'type'. I can't seem to get it to work! $(document).ready(function(){ $("#healthForm").validate({ highlight: function(element, errorClass) { $(element).addClass(errorClass) $(element.form).find("label[for='type']") .addClass("radioerror"); }, unhighlight: function(element, errorClass) { $(element).removeClass(errorClass) $(element.form).find("label[for='type']") .removeClass("radioerror"); }, errorPlacement: function(error, element) { } }); });

• Entity framework - exclude list of values

  - by DutrowLLC

  Is there a way to exclude a list of values for an object attribute when querying the database through entity framework? I tried to be slick and pull this number: List<String> StringList = new List<String>(); StringList.Add("ya_mama"); StringList.Add("has"); StringList.Add("fleas"); servicesEntities context = new servicesEntities(); var NoFleasQuery = (from x in context.person where !StringList.Any(y => y.CompareTo(x.the_string_I_dont_want_it_to_be) == 0) // <--- the part where I thought I was slick select x); ...it compiled, but after I ran it, it gave me this error: Unable to create a constant value of type 'Closure type'. Only primitive types ('such as Int32, String, and Guid') are supported in this context. 'Closure type'???? How about MY closure!!! Entity framework... you broke my heart.

• Mapping a boolean[] PostgreSql column with Hibernate

  - by teabot

  I have a column in a PostgreSql database that is defined with type boolean[]. I wish to map this to a Java entity property using Hibernate 3.3.x. However, I cannot find a suitable Java type that Hibernate is happy to map to. I thought that the java.lang.Boolean[] would be the obvious choice, but Hibernate complains: Caused by: org.hibernate.HibernateException: Wrong column type in schema.table for column mycolumn. Found: _bool, expected: bytea at org.hibernate.mapping.Table.validateColumns(Table.java:284) at org.hibernate.cfg.Configuration.validateSchema(Configuration.java:1130) I have also tried the following property types without success: java.lang.String java.lang.boolean[] java.lang.Byte[] How can I map this column?

• what POIs (Point of Interests) DB can I use for a commercial app

  - by Ellie

  Hi, I need a POI database for a startup project I am working on - it will be a free basic version and a premium paid for version in the sense that user will pay a monthly subscription. I would like to use foursquare type checkin to places and plancast type functionality to search for places (one-line search). Ie I need to: - perform a search for POIs around a location - associate users to that POI, with a time stamp - allow users to add own POIs - provide free-text search for POIs (a la google one-line search) Google API allows great search, but I understand there are limits in number of requests that can be done? This would prevent scaling, and may result in application breaking when too many users. Also what does google T&C say about using this in a paid for service? Openstreetmap I understand does not have these contstraints, but do they also provide a good one-line search type API? Or how could I solve this? Many thanks for any advice, Ellie

• Enter Password in C

  - by Mohit Deshpande

  I am aware that it is not possible to echo the * while you type in standard ANSI C. But is there a way to display nothing while someone is typing their password in the console. What I mean is like the sudo prompts in a Unix/Linux terminal. Like if you type in the command: sudo cp /etc/somefile ~/somedir. You are usually prompted for the root password. And while you type it in, the terminal displays nothing. Is this effect possible in C? If it is, how?

• nginx probably deliering wrong filetype for .css file with php tags

  - by Katai

  And again - NGINX is giving me many Questions today :) Like always, I already tried around for a while, but cant seem to fix this issue: I just configured NGINX to handle my .css files equal to my .php files (to parse PHP tags inside the CSS file). This works perfectly, and the file is found and delivered. I could debug it with FIrebug, and everything is OK (it displays the contents of the .css inside the opened <link> tag). So, everything working, right? Wrong. It has the CSS, but it does not interpret it! What I mean by this: apparently, the file-type of the CSS (or aplication-type, whatever) is wrong. The Page can access the CSS, but doesnt bother at all to actually use it. What I checked / tried: There are no PHP errors inside of the .css, so that one is out The .css is accessible. I can call the URI manually, or check if the included URL finds it: both works The .css has no syntax errors (i switched to a css that just has body {background-color: #000; } It works whitout NGINX I deleted the browser cache / restarted NGINX after config rewrites Here the configuration: server { listen 80; server_name localhost; access_log /var/log/nginx/board.access_log; error_log /var/log/nginx/board.error_log warn; root /var/www/board/public; index index.php; fastcgi_index index.php; location / { try_files $uri $uri /index.php; } location ~ (\.php|\.css)$ { try_files $uri =404; include /etc/nginx/fastcgi_params; #keepalive_timeout 0; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_pass 127.0.0.1:7777; } } Firebug 'Network' Response Header: Connection keep-alive Content-Encoding gzip Content-Type text/html Date Sat, 16 Jun 2012 10:08:40 GMT Server nginx/1.0.5 Transfer-Encoding chunked X-Powered-By PHP/5.3.6-13ubuntu3.7 I think I just answered my own question. Is the Content-Type text/html the problem? How can I remove that? My personal guess is that I have to use this in some way include /etc/nginx/mime.types; default_type application/octet-stream; But I'm not sure... anyone an idea how to solve this? TLDR; CSS file is delivered correctly, but it doesnt seem to be 'used' as CSS from the browser. (Tested, works on apache)

• Using ninject/autofac for a given scenario

  - by sandesh247

  I have some providers, say - <Providers> <Provider Type="Providers.IM" Name="Im"/> <Provider Type="Providers.Web" Name="Web"/> ... </Provider> Each of these providers can give me a session : <Sessions> <Session Name="GoogleIM" Provider="Im" URL="..." /> <Session Name="YahooIM" Provider="Im" URL="..." /> <Session Name="YahooWeb" Provider="Web" URL="..." /> ... </Session> Currently, I instantiate "named" sessions by looking at the provider, instantiating the type, and injecting the URL (manually). I could use a session factory, which would probably have to understand the url and return a proper session. Is there a way to handle this more elegantly/simply with ninject/autofac?

• Pushing data once a URL is requested

  - by Eli Grey

  Given, when a user requests /foo on my server, I send the following HTTP response (not closing the connection): Content-Type: multipart/x-mixed-replace; boundary=----------------------- ----------------------- Content-Type: text/html <a href="/bar">foo</a> When the user clicks on foo (which will send 204 No Content so the view doesn't change), I want to send the following data in the initial response. ----------------------- Content-Type: text/html bar How would could I get the second request to trigger this from the initial response? I'm planning on possibly creating a fancy [engines that support multipart/x-mixed-replace (currently only Gecko)]-only email webapp that does server-push and Ajax effects without any JavaScript, just for fun.

• Configure Hibernate validation for bean

  - by sergionni

  Hi. I need to perform validation based on SQL query result. Query is defined as annotation - as @NamedQuery in my entity bean. According to Hibernate documentation(doc), there is possibility to validate bean on following operations: pre-update pre-insert pre-delete looks like: <hibernate-configuration> <session-factory> ... <event type="pre-update"> <listener class="org.hibernate.cfg.beanvalidation.BeanValidationEventListener"/> </event> <event type="pre-insert"> <listener class="org.hibernate.cfg.beanvalidation.BeanValidationEventListener"/> </event> <event type="pre-delete"> <listener class="org.hibernate.cfg.beanvalidation.BeanValidationEventListener"/> </event> </hibernate-configuration> The question is how to connect my bean with the validation configuration, described above.

• Connect ps/2->usb keyboard to linux?

  - by Daniel

  I have a lovely ancient ergonomic keyboard (no name SK - 6000) connected via a DIN-ps/2 adapter to a ps/2-usb adapter to my docking station. After Grub it stops working. It takes either suspending and waking up or replugging it while Linux is running to get it to work. No extra kernel modules get loaded for this. When it works and I restart without power off, it will work immediately. Even when it does not work, it is visible (lsusb device number varies but output is identical whether working or not): $ lsusb -v -s 001:006 Bus 001 Device 006: ID 0a81:0205 Chesen Electronics Corp.

• Bind multiple request parameters to one object in Spring 3

  - by Max

  Hi, I can't figure out a way to bind several arguments and headers to one request parameter using annotations in Spring 3. For example, let's say I'm getting this request: Headers: Content-type: text/plain; POST Body: Name: Max Now I want it all to mysteriously bind to this object: class NameInfo { String name; } Using some code like this: String getName() { if ("text/plain".equals(headers.get("content-type"))) { return body.get("name"); } else if ("xml".equals(headers.get("content-type")) { return parseXml(body).get("name"); } else ... } So that in the end I would be able to use: @RequestMapping(method = RequestMethod.POST) void processName(@RequestAttribute NameInfo name) { ... } Is there a way to achieve something similar to what I need? Thanks in advance.

• WPF Binding Collection To ComboBox and Selecting an item

  - by Adam Driscoll

  I've been knocking my head against this for some time now. I'm not really sure why it isn't working. I'm still pretty new to this whole WPF business. Here's my XAML for the combobox <ComboBox Width="200" SelectedValuePath="Type.FullName" SelectedItem="{Binding Path=Type}" Name="cmoBox" > </ComboBox> Here's what populates the ComboBox (myAssembly is a class I created with a list of possible types) cmoBox.ItemsSource = myAssembly.PossibleTypes; I set the DataContext in a parent element of the ComboBox in the code behind like this: groupBox.DataContext = listBox.SelectedItem; I want the binding to select the correct "possible type" from the combo box. It doesn't select anything. I have tried SelectedValue and SelectedItem. When I changed the DisplayMemberPath of the ComboBox to a different property it changed what was displayed so I know it's not completely broken. Any ideas???

• boost::Spirit Grammar for unsorted schema

  - by Hassan Syed

  I have a section of a schema for a model that I need to parse. Lets say it looks like the following. { type = "Standard"; hostname="x.y.z"; port="123"; } The properties are: The elements may appear unordered. All elements that are part of the schema must appear, and no other. All of the elements' synthesised attributes go into a struct. (optional) The schema might in the future depend on the type field -- i.e., different fields based on type -- however I am not concerned about this at the moment.

• Code working in jsFiddle but not in browser...

  - by Jascination

  I'm trying to run the following code, written on my local machine: http://www.jsfiddle.net/WShdx/3/ Functionality-wise (ignore the broken images in the previous and next buttons, and the wrongly-sized main images) the click/hover function is working properly in jsfiddle. However, on my local machine it's not working at all. For all intents and purposes the code is identical, except the local copy has this head section to load in the javascript/css files that are contained within the jsfiddle page: <head> <title>Jquery Wizard</title> <link href="style.css" rel="stylesheet" type="text/css" /> <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script> <script src="wizard.js" type="text/javascript" ></script> </head> Is there some wonderful function of jsFiddle that is making my code magically work, or am I missing something here?

  - by Josh

  Hi all, JQuery noobie here - i'm trying to make a pager using radio buttons with the JQuery Cycle pageAnchorBuilder. The transitions all seem to work ok, except but it is not possible to select a radio button. Any help much appreciated! Cheers Here is my JavaScript code: $('.products').cycle({ fx: 'scrollHorz', speed: 300, timeout: 0, pager: '#nav', pagerAnchorBuilder: function(idx, slide) { return '#nav input:eq(' +idx +')'; } }); HTML is here: <ul id="nav"> <li><input type="radio" name="style" id="style1" value="Style 1" /><label for="style1">Style 1</label></li> <li><input type="radio" name="style" id="style2" value="Style 2" /><label for="style2">Style 2</label></li> <li><input type="radio" name="style" id="style3" value="Style 3" /><label for="style3">Style 3</label></li> </ul>

• How can I disable Control-W in Windows XP?

  - by Tim Visher

  I'm an Emacs/Mac user trapped on Windows at work and I often type Control-W from muscle memory to delete a word and thus by mistake kill the entire window, including everything that I was working on. This a particularly egregious problem for Console2 as I run GNU Screen and am often doing many things at once. Is there any way to completely disable Control-W or remap it to something that is far harder to type? Thanks!

• How do I check if a user is a fan of my facebook page on my website?

  - by Tony

  I want to check if my users are fans of my facebook page. I think something like this should do it: <script type="text/javascript" src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php/en_US"></script> <script type="text/javascript">FB.init("my api key","xd_receiver.htm");</script> <script type="text/javascript"> //<![CDATA[ FB_RequireFeatures(["Api"], function(){ var api = FB.Facebook.apiClient; api.pages_isFan(PAGE_ID,gigyaUser.FACEBOOK_USER_ID,function(response){ alert(response); }); }); //]]> </script> However, for some reason I keep getting null even though the user is in fact a fan of the page. Am I missing something?

  - by Cheba

  I've managed to make it play sound but it never gets EOS message. And thus script never exits. require 'gst' main_loop = GLib::MainLoop.new pipeline = Gst::Pipeline.new "audio-player" source = Gst::ElementFactory.make "filesrc", "file-source" source.location = "/usr/share/sounds/gnome/default/alerts/bark.ogg" decoder = Gst::ElementFactory.make "decodebin", "decoder" conv = Gst::ElementFactory.make "audioconvert", "converter" sink = Gst::ElementFactory.make "alsasink", "output" pipeline.add source, decoder, conv, sink source >> decoder conv >> sink decoder.signal_connect "pad-added" do |element, pad, data| pad >> conv['sink'] end pipeline.bus.add_watch do |bus, message| puts "Message: #{message.inspect}" case message.type when Gst::Message::Type::ERROR puts message.structure["debug"] main_loop.quit when Gst::Message::Type::EOS puts 'End of stream' main_loop.quit end end pipeline.play begin puts 'Running main loop' main_loop.run ensure puts 'Shutting down main loop' pipeline.stop end
