  • place to host a simple php socket server

    - by bonusbox
    i am running a small project that occasionally requires me to run a php socket script through ssh. it uses a few bytes of bandwidth (just some text) which activates my art installation project. i tried a simple web hosting plan but that didn't support sockets, so know i am using a 32$ vps plan on namecheap.com just to run a simple php script. i don't really need to host anything else on it. i find it kind of excessive for such a simple thing. is there a place i can run my script for a lower cost? any servers that support php sockets and ssh?

  • how to read the password from variable?

    - by Viswa
    I am trying to move my file to another system which is located in some other place, with this command: rsync -avrz src destination It works fine. But what I need is to put this command in shell script and run it like: #! /bin/sh rsync -avrz srcfilelocation destination When it runs, it asks for the destination system password. I know that password and give it manually. Now I have decided to assign the password to an environment variable, like pswd="destination system password". I need my shell script to read the password from this variable. How can I write a script to do this?

  • Is there a debian/ubuntu policy on softlinking things to another location in opt once they're installed?

    - by AbrahamVanHelpsing
    Is there a debian/ubuntu policy on softlinking things to another location in opt once they're installed properly in usr/share or usr/lib? Here's a simple example: Packaging up dnsenum. It's a REALLY simple package (4 files). A perl script, two wordlists, and a readme. So from what I gather: The wordlists should go in usr/share/dnsenum/* The perl script itself would go in usr/lib/dnsenum/ The readme would go in usr/share/doc/dnsenum/ Add a wrapper bash script that goes in bin and just passes arguments to dnsenum.pl. The question is this: If there are various tools that provide wordlists or some other shared resource, is there a policy on linking all the wordlists from different packages in to /opt/wordlists/ ? It seems like the "right" thing to do respecting the directory structure while still making things convenient.

  • How to automatically restart Tomcat7 on system reboots?

    - by coding crow
    I have installed Tomcat 7 on Ubuntu 12.04 LTS which run on an Amzon EC2 instance. Now I wish tomcat should restart automatically on system reboot. I read this blog which suggest adding below script to /etc/init.d/tomcat7 # Tomcat auto-start # # description: Auto-starts tomcat # processname: tomcat # pidfile: /var/run/tomcat.pid case $1 in start) sh /usr/share/tomcat7/bin/startup.sh ;; stop) sh /usr/share/tomcat7/bin/shutdown.sh ;; restart) sh /usr/share/tomcat7/bin/shutdown.sh sh /usr/share/tomcat7/bin/startup.sh ;; esac exit 0 and issue the following commands sudo chmod 755 /etc/init.d/tomcat7 sudo ln -s /etc/init.d/tomcat7 /etc/rc1.d/K99tomcat sudo ln -s /etc/init.d/tomcat7 /etc/rc2.d/S99tomcat sudo /etc/init.d/tomcat7 restart My Questions The tomcat7 already has script in it, where do we have to paste the suggested script?

  • How to work around the home directory changing to /root when using sudo?

    - by Nathanel Titane
    Hello everybody! With Natty coming out soon, I've been at work updating my deployment and self-config script to make my desktop on 11.04 run and look the way I want it to. One bummer is that dbus seems to have changed and does not permit, in the same manner Lucid and Maverick did, the authentication of the current user by terminal call using grep and cat. Ideally, to run the script, I would sudo -s and then launch it as # chmod +x install && ./install Instead of returning my user name.. it now returns root and applies changes to the root profile and aborts whenever paths do not correspond. Here is my script header: #!/bin/bash ON_USER=$(echo ~ | awk -F'/' '{ print $1 $2 $3 }' | sed 's/home//g') export $(grep -v "^#" ~/.dbus/session-bus/`cat /var/lib/dbus/machine-id`-0) if sudo -u $ON_USER test -z "$DBUS_SESSION_BUS_ADDRESS" ; then eval `sudo -u $ON_USER dbus-launch --sh-syntax --exit-with-session` fi RELEASE=$(lsb_release -cs) How could I make it return the actual user now that natty is coming? Thanks for the help

  • How to run/test JavaScript? [closed]

    - by user702
    I'm reading David Flanagan's "JavaScript: The Definitive Guide, 6th ed". It only actually tells users how to run JS code on page 311, where users are told of the following solutions: "Client-side JavaScript code is embedded within HTML documents in four ways: Inline, between a pair of <script> and </script> tags From an external file specified by the src attribute in a <script> tag In an HTML event handler attribute, such as onclick or onmouseover In a URL that uses the special javascript: protocol." I was wondering what professional JS developers use to write and test their code: Do they use a good text editor with syntax high-lighting + autocompletion, hit F5 in the browser to reload the page every time they make a change, and use some add-on in the browser to investigate errors? Or are there full-fledged IDE's similar to MS VisualStudio for non-web languages?

  • Check for Instant File Initialization

    - by TiborKaraszi
    Instant File initialization, IFI, is generally a good thing to have. Check out this earlier blog post of mine f you don't know what IFI is and why it is a good thing: blog . The purpose of this blog post is to provide a simple script you can use to check if you have IFI turned on. Note that the script below uses undocumented commands, and might take a while if you have a large errorlog file... USE MASTER ; SET NOCOUNT ON -- *** WARNING: Undocumented commands used in this script !!! *** -- --Exit...(read more)

  • Is there a way to setup Clicktale tag in Google Tag Manager?

    - by Cubius
    Since GTM doesn't support document.write() method the standard clicktale code doesn't work. Is there a workaround for this? ClickTale employee has sent me these instructions: Replace the document.write JS line above with the following: document.body.appendChild(externalScript); Example: <!-- ClickTale Bottom part --> <script type='text/javascript'> var externalScript = document.createElement('script'); var scrSrc = document.location.protocol=='https:'? 'https://clicktalecdn.sslcs.cdngc.net/': 'http://cdn.clicktale.net/'; scrSrc += 'www11/ptc/xxx-xxx-xxx-xxx.js'; externalScript.src = scrSrc; externalScript.type = 'text/javascript'; document.body.appendChild(externalScript); </script> <!-- ClickTale end of Bottom part --> I am not sure what to do with this. Has someone tried something like this?

  • Print out the amount of times 2 words appear in the syslog. But also have it tell me how many times for each hour

    - by wolfspinone
    So I'm trying to create a bash script that looks for two words in my syslog file. Then I want the script to print out how many times those two words have appeared. Also I want it to print it out for every hour of the day. So like if the word dog appeared 4 times during the first hour of today, it says Hour one, dog 4. Finally at the end of the script I want it to print out how many times those words appeared all day. The sudo code I have thus far is if 2 > hour find permit find block print both finish if 1 < hour < 2 find permit find block print both finish if 2 < hour < 3 find permit find block print both finish command is grep -o "\WORD\" Syslog.txt * | sort | uniq -c

  • Google analytics shows wrong number of page views, asp.net website

    - by f_karlsson
    Sometimes it can be for example 4500 requests, after a few hours it shows a few thousand less. What is wrong? It looks like analytics corrects itself. I changed from classic to Universal a few months ago, do not know if it has anything to do with this. In masterpage: <script> (function (i, s, o, g, r, a, m) { i['GoogleAnalyticsObject'] = r; i[r] = i[r] || function () { (i[r].q = i[r].q || []).push(arguments) }, i[r].l = 1 * new Date(); a = s.createElement(o), m = s.getElementsByTagName(o)[0]; a.async = 1; a.src = g; m.parentNode.insertBefore(a, m) })(window, document, 'script', '//www.google-analytics.com/analytics.js', 'ga'); ga('create', 'UA-xxxxxxxx-1', 'xxxxx.se'); ga('send', 'pageview'); </script>

  • Terminal echo issue

    - by user107602
    I've been using Ubuntu 10.04 LTS for a while, am quite new, using the terminal, made a script to open a project of mine containing multiple files with gedit - after execution of the respective script - gedit [filename1] [filename2] ... , terminal executes it successfully, gedit opens passed files and terminal is ready for another line. Well, today I came across a strange issue - after the execution of the above mentioned script, gedit initiates successfully, but terminal denies execution of commands and echoes all keyboard events, even specific ctrl+... functions - all until gedit is closed. I can't figure what caused this as my recent activity was focused around a C project, not regarding the terminal in any way. I recall being able to execute another line after initiating e.g. open gedit and compile a project within a single tab and session of a terminal window. Any help would be appreciated! Regards!

  • Using Google Tag Manager to define the page type

    - by Daffy
    So, I am looking to add a tag that I want to use for A/B testing, however we don't have a page-type URL structure. Fortunately the tool can recognise page type if I pass it by Javascript. <script type="text/javascript"> window.isProductPage = true; </script> I have been told to use the above, I have created the script in Google Tag Manager (GTM), however I now need to know how to make this run on those pages in GTM. I have looked through the code and there are div class that are unique to each page, can I use this as an indication of page type?

  • Why is there a /etc/init.d/mysql file on this Slackware machine? How could it have gotten there?

    - by jasonspiro
    A client of my IT-consulting service owns a web-development shop. He's been having problems with a Slackware 12.0 server running MySQL 5.0.67.

  • Mobile enabled web apps with ASP.NET MVC 3 and jQuery Mobile

    - by shiju
    In my previous blog posts, I have demonstrated a simple web app using ASP.NET MVC 3 and EF Code First. In this post, I will be focus on making this application for mobile devices. A single web site will be used for both mobile browsers and desktop browsers. If users are accessing the web app from mobile browsers, users will be redirect to mobile specific pages and will get normal pages if users are accessing from desktop browsers. In this demo app, the mobile specific pages are maintained in an ASP.NET MVC Area named Mobile and mobile users will be redirect to MVC Area Mobile. Let’s add a new area named Mobile to the ASP.NET MVC app. For adding Area, right click the ASP.NET MVC project and  select Area from Add option. Our mobile specific pages using jQuery Mobile will be maintained in the Mobile Area. ASP.NET MVC Global filter for redirecting mobile visitors to Mobile area Let’s add an ASP.NET MVC Global filter for redirecting mobile visitors to Mobile area. The below Global filter is taken from the sample app http://aspnetmobilesamples.codeplex.com/ created by the ASP.NET team. The below filer will redirect the Mobile visitors to an ASP.NET MVC Area Mobile. public class RedirectMobileDevicesToMobileAreaAttribute : AuthorizeAttribute     {         protected override bool AuthorizeCore(System.Web.HttpContextBase httpContext)         {             // Only redirect on the first request in a session             if (!httpContext.Session.IsNewSession)                 return true;               // Don't redirect non-mobile browsers             if (!httpContext.Request.Browser.IsMobileDevice)                 return true;               // Don't redirect requests for the Mobile area             if (Regex.IsMatch(httpContext.Request.Url.PathAndQuery, "/Mobile($|/)"))                 return true;               return false;         }           protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)         {             var redirectionRouteValues = GetRedirectionRouteValues(filterContext.RequestContext);             filterContext.Result = new RedirectToRouteResult(redirectionRouteValues);         }           // Override this method if you want to customize the controller/action/parameters to which         // mobile users would be redirected. This lets you redirect users to the mobile equivalent         // of whatever resource they originally requested.         protected virtual RouteValueDictionary GetRedirectionRouteValues(RequestContext requestContext)         {             return new RouteValueDictionary(new { area = "Mobile", controller = "Home", action = "Index" });         }     } Let’s add the global filer RedirectMobileDevicesToMobileAreaAttribute to the global filter collection in the Application_Start() of Global.asax.cs file   GlobalFilters.Filters.Add(new RedirectMobileDevicesToMobileAreaAttribute(), 1); Now your mobile visitors will be redirect to the Mobile area. But the browser detection logic in the RedirectMobileDevicesToMobileAreaAttribute filter will not be working in some modern browsers and some conditions. But the good news is that ASP.NET’s browser detection feature is extensible and will be greatly working with the open source framework 51Degrees.mobi. 51Degrees.mobi is a Browser Capabilities Provider that will be working with ASP.NET’s Request.Browser and will provide more accurate and detailed information. For more details visit the documentation page at http://51degrees.codeplex.com/documentation. Let’s add a reference to 51Degrees.mobi library using NuGet We can easily add the 51Degrees.mobi from NuGet and this will update the web.config for necessary configuartions. Mobile Web App using jQuery Mobile Framework jQuery Mobile Framework is built on top of jQuery that provides top-of-the-line JavaScript in a unified User Interface that works across the most-used smartphone web browsers and tablet form factors. It provides an easy way to develop user interfaces for mobile web apps. The current version of the framework is jQuery Mobile Alpha 3. We need to include the following files to use jQuery Mobile. The jQuery Mobile CSS file (jquery.mobile-1.0a3.min.css) The jQuery library (jquery-1.5.min.js) The jQuery Mobile library (jquery.mobile-1.0a3.min.js) Let’s add the required jQuery files directly from jQuery CDN . You can download the files and host them on your own server. jQuery Mobile page structure The basic jQuery Mobile page structure is given below <!DOCTYPE html> <html>   <head>   <title>Page Title</title>   <link rel="stylesheet" href="http://code.jquery.com/mobile/1.0a3/jquery.mobile-1.0a1.min.css" />   <script src="http://code.jquery.com/jquery-1.5.min.js"></script>   <script src="http://code.jquery.com/mobile/1.0a3/jquery.mobile-1.0a3.min.js"></script> </head> <body> <div data-role="page">   <div data-role="header">     <h1>Page Title</h1>   </div>   <div data-role="content">     <p>Page content goes here.</p>      </div>   <div data-role="footer">     <h4>Page Footer</h4>   </div> </div> </body> </html> The data- attributes are the new feature of HTML5 so that jQuery Mobile will be working on browsers that supporting HTML 5. You can get a detailed browser support details from http://jquerymobile.com/gbs/ . In the Head section we have included the Core jQuery javascript file and jQuery Mobile Library and the core CSS Library for the UI Element Styling. These jQuery files are minified versions and will improve the performance of page load on Mobile Devices. The jQuery Mobile pages are identified with an element with the data-role="page" attribute inside the <body> tag. <div data-role="page"> </div> Within the "page" container, any valid HTML markup can be used, but for typical pages in jQuery Mobile, the immediate children of a "page" are div element with data-roles of "header", "content", and "footer". <div data-role="page">     <div data-role="header">...</div>     <div data-role="content">...</div>     <div data-role="footer">...</div> </div> The div data-role="content" holds the main content of the HTML page and will be used for making user interaction elements. The div data-role="header" is header part of the page and div data-role="footer" is the footer part of the page. Creating Mobile specific pages in the Mobile Area Let’s create Layout page for our Mobile area <!DOCTYPE html> <html> <head>     <title>@ViewBag.Title</title>     <link rel="stylesheet" href="http://code.jquery.com/mobile/1.0a3/jquery.mobile-1.0a3.min.css" />     <script src="http://code.jquery.com/jquery-1.5.min.js"></script>     <script src="http://code.jquery.com/mobile/1.0a3/jquery.mobile-1.0a3.min.js"></script>     </head>      <body> @RenderBody()    </body> </html> In the Layout page, I have given reference to jQuery Mobile JavaScript files and the CSS file. Let’s add an Index view page Index.chtml @{     ViewBag.Title = "Index"; } <div data-role="page"> <div data-role="header">      <h1>Expense Tracker Mobile</h1> </div> <div data-role="content">   <ul data-role="listview">     <li>@Html.Partial("_LogOnPartial")</li>      <li>@Html.ActionLink("Home", "Index", "Home")</li>      <li>@Html.ActionLink("Category", "Index", "Category")</li>                          <li>@Html.ActionLink("Expense", "Index", "Expense")</li> </ul> </div> <div data-role="footer">           Shiju Varghese | <a href="http://weblogs.asp.net/shijuvarghese">Blog     </a> | <a href="http://twitter.com/shijucv">Twitter</a>   </div> </div>   In the Index page, we have used data-role “listview” for showing our content as List View Let’s create a data entry screen create.cshtml @model MyFinance.Domain.Category @{     ViewBag.Title = "Create Category"; }   <div data-role="page"> <div data-role="header">      <h1>Create Category</h1>             @Html.ActionLink("Home", "Index","Home",null, new { @class = "ui-btn-right" })      </div>       <div data-role="content">     @using (Html.BeginForm("Create","Category",FormMethod.Post))     {       <div data-role="fieldcontain">        @Html.LabelFor(model => model.Name)        @Html.EditorFor(model => model.Name)        <div>           @Html.ValidationMessageFor(m => m.Name)        </div>         </div>         <div data-role="fieldcontain">         @Html.LabelFor(model => model.Description)         @Html.EditorFor(model => model.Description)                   </div>                    <div class="ui-body ui-body-b">         <button type="submit" data-role="button" data-theme="b">Save</button>       </div>     }        </div> </div>   In jQuery Mobile, the form elements should be placed inside the data-role="fieldcontain" The below screen shots show the pages rendered in mobile browser Index Page Create Page Source Code You can download the source code from http://efmvc.codeplex.com   Summary We have created a single  web app for desktop browsers and mobile browsers. If a user access the site from desktop browsers, users will get normal web pages and get mobile specific pages if users access from mobile browsers. If users are accessing the website from mobile devices, we will redirect to a ASP.NET MVC area Mobile. For redirecting to the Mobile area, we have used a Global filer for the redirection logic and used open source framework 51Degrees.mobi for the better support for mobile browser detection. In the Mobile area, we have created the pages using jQuery Mobile and users will get mobile friendly web pages. We can create great mobile web apps using ASP.NET MVC  and jQuery Mobile Framework.

  • Metro Walkthrough: Creating a Task List with a ListView and IndexedDB

    - by Stephen.Walther
    The goal of this blog entry is to describe how you can work with data in a Metro style application written with JavaScript. In particular, we create a super simple Task List application which enables you to create and delete tasks. Here’s a video which demonstrates how the Task List application works: In order to build this application, I had to take advantage of several features of the WinJS library and technologies including: IndexedDB – The Task List application stores data in an IndexedDB database. HTML5 Form Validation – The Task List application uses HTML5 validation to ensure that a required field has a value. ListView Control – The Task List application displays the tasks retrieved from the IndexedDB database in a WinJS ListView control. Creating the IndexedDB Database The Task List application stores all of its data in an IndexedDB database named TasksDB. This database is opened/created with the following code: var db; var req = window.msIndexedDB.open("TasksDB", 1); req.onerror = function () { console.log("Could not open database"); }; req.onupgradeneeded = function (evt) { var newDB = evt.target.result; newDB.createObjectStore("tasks", { keyPath: "id", autoIncrement:true }); }; The msIndexedDB.open() method accepts two parameters: the name of the database to open and the version of the database to open. If a database with a matching version already exists, then calling the msIndexedDB.open() method opens a connection to the existing database. If the database does not exist then the upgradeneeded event is raised. You handle the upgradeneeded event to create a new database. In the code above, the upgradeneeded event handler creates an object store named “tasks” (An object store roughly corresponds to a database table). When you add items to the tasks object store then each item gets an id property with an auto-incremented value automatically. The code above also includes an error event handler. If the IndexedDB database cannot be opened or created, for whatever reason, then an error message is written to the Visual Studio JavaScript Console window. Displaying a List of Tasks The TaskList application retrieves its list of tasks from the tasks object store, which we created above, and displays the list of tasks in a ListView control. Here is how the ListView control is declared: <div id="tasksListView" data-win-control="WinJS.UI.ListView" data-win-options="{ itemDataSource: TaskList.tasks.dataSource, itemTemplate: select('#taskTemplate'), tapBehavior: 'toggleSelect', selectionMode: 'multi', layout: { type: WinJS.UI.ListLayout } }"> </div> The ListView control is bound to the TaskList.tasks.dataSource data source. The TaskList.tasks.dataSource is created with the following code: // Create the data source var tasks = new WinJS.Binding.List(); // Open the database var db; var req = window.msIndexedDB.open("TasksDB", 1); req.onerror = function () { console.log("Could not open database"); }; req.onupgradeneeded = function (evt) { var newDB = evt.target.result; newDB.createObjectStore("tasks", { keyPath: "id", autoIncrement:true }); }; // Load the data source with data from the database req.onsuccess = function () { db = req.result; var tran = db.transaction("tasks"); tran.objectStore("tasks").openCursor().onsuccess = function(event) { var cursor = event.target.result; if (cursor) { tasks.dataSource.insertAtEnd(null, cursor.value); cursor.continue(); }; }; }; // Expose the data source and functions WinJS.Namespace.define("TaskList", { tasks: tasks }); Notice the success event handler. This handler is called when a database is successfully opened/created. In the code above, all of the items from the tasks object store are retrieved into a cursor and added to a WinJS.Binding.List object named tasks. Because the ListView control is bound to the WinJS.Binding.List object, copying the tasks from the object store into the WinJS.Binding.List object causes the tasks to appear in the ListView: Adding a New Task You add a new task in the Task List application by entering the title of a new task into an HTML form and clicking the Add button. Here’s the markup for creating the form: <form id="addTaskForm"> <input id="newTaskTitle" title="New Task" required /> <button>Add</button> </form> Notice that the INPUT element includes a required attribute. In a Metro application, you can take advantage of HTML5 Validation to validate form fields. If you don’t enter a value for the newTaskTitle field then the following validation error message is displayed: For a brief introduction to HTML5 validation, see my previous blog entry: http://stephenwalther.com/blog/archive/2012/03/13/html5-form-validation.aspx When you click the Add button, the form is submitted and the form submit event is raised. The following code is executed in the default.js file: // Handle Add Task document.getElementById("addTaskForm").addEventListener("submit", function (evt) { evt.preventDefault(); var newTaskTitle = document.getElementById("newTaskTitle"); TaskList.addTask({ title: newTaskTitle.value }); newTaskTitle.value = ""; }); The code above retrieves the title of the new task and calls the addTask() method in the tasks.js file. Here’s the code for the addTask() method which is responsible for actually adding the new task to the IndexedDB database: // Add a new task function addTask(taskToAdd) { var transaction = db.transaction("tasks", "readwrite"); var addRequest = transaction.objectStore("tasks").add(taskToAdd); addRequest.onsuccess = function (evt) { taskToAdd.id = evt.target.result; tasks.dataSource.insertAtEnd(null, taskToAdd); } } The code above does two things. First, it adds the new task to the tasks object store in the IndexedDB database. Second, it adds the new task to the data source bound to the ListView. The dataSource.insertAtEnd() method is called to add the new task to the data source so the new task will appear in the ListView (with a nice little animation). Deleting Existing Tasks The Task List application enables you to select one or more tasks by clicking or tapping on one or more tasks in the ListView. When you click the Delete button, the selected tasks are removed from both the IndexedDB database and the ListView. For example, in the following screenshot, two tasks are selected. The selected tasks appear with a teal background and a checkmark: When you click the Delete button, the following code in the default.js file is executed: // Handle Delete Tasks document.getElementById("btnDeleteTasks").addEventListener("click", function (evt) { tasksListView.winControl.selection.getItems().then(function(items) { items.forEach(function (item) { TaskList.deleteTask(item); }); }); }); The selected tasks are retrieved with the TaskList selection.getItem() method. In the code above, the deleteTask() method is called for each of the selected tasks. Here’s the code for the deleteTask() method: // Delete an existing task function deleteTask(listViewItem) { // Database key != ListView key var dbKey = listViewItem.data.id; var listViewKey = listViewItem.key; // Remove item from db and, if success, remove item from ListView var transaction = db.transaction("tasks", “readwrite”); var deleteRequest = transaction.objectStore("tasks").delete(dbKey); deleteRequest.onsuccess = function () { tasks.dataSource.remove(listViewKey); } } This code does two things: it deletes the existing task from the database and removes the existing task from the ListView. In both cases, the right task is removed by using the key associated with the task. However, the task key is different in the case of the database and in the case of the ListView. In the case of the database, the task key is the value of the task id property. In the case of the ListView, on the other hand, the task key is auto-generated by the ListView. When the task is removed from the ListView, an animation is used to collapse the tasks which appear above and below the task which was removed. The Complete Code Above, I did a lot of jumping around between different files in the application and I left out sections of code. For the sake of completeness, I want to include the entire code here: the default.html, default.js, and tasks.js files. Here are the contents of the default.html file. This file contains the UI for the Task List application: <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>Task List</title> <!-- WinJS references --> <link href="//Microsoft.WinJS.0.6/css/ui-dark.css" rel="stylesheet"> <script src="//Microsoft.WinJS.0.6/js/base.js"></script> <script src="//Microsoft.WinJS.0.6/js/ui.js"></script> <!-- TaskList references --> <link href="/css/default.css" rel="stylesheet"> <script src="/js/default.js"></script> <script type="text/javascript" src="js/tasks.js"></script> <style type="text/css"> body { font-size: x-large; } form { display: inline; } #appContainer { margin: 20px; width: 600px; } .win-container { padding: 10px; } </style> </head> <body> <div> <!-- Templates --> <div id="taskTemplate" data-win-control="WinJS.Binding.Template"> <div> <span data-win-bind="innerText:title"></span> </div> </div> <h1>Super Task List</h1> <div id="appContainer"> <form id="addTaskForm"> <input id="newTaskTitle" title="New Task" required /> <button>Add</button> </form> <button id="btnDeleteTasks">Delete</button> <div id="tasksListView" data-win-control="WinJS.UI.ListView" data-win-options="{ itemDataSource: TaskList.tasks.dataSource, itemTemplate: select('#taskTemplate'), tapBehavior: 'toggleSelect', selectionMode: 'multi', layout: { type: WinJS.UI.ListLayout } }"> </div> </div> </div> </body> </html> Here is the code for the default.js file.

  • Metro Walkthrough: Creating a Task List with a ListView and IndexedDB

    - by Stephen.Walther
    The goal of this blog entry is to describe how you can work with data in a Metro style application written with JavaScript. In particular, we create a super simple Task List application which enables you to create and delete tasks. Here’s a video which demonstrates how the Task List application works: In order to build this application, I had to take advantage of several features of the WinJS library and technologies including: IndexedDB – The Task List application stores data in an IndexedDB database. HTML5 Form Validation – The Task List application uses HTML5 validation to ensure that a required field has a value. ListView Control – The Task List application displays the tasks retrieved from the IndexedDB database in a WinJS ListView control. Creating the IndexedDB Database The Task List application stores all of its data in an IndexedDB database named TasksDB. This database is opened/created with the following code: var db; var req = window.msIndexedDB.open("TasksDB", 1); req.onerror = function () { console.log("Could not open database"); }; req.onupgradeneeded = function (evt) { var newDB = evt.target.result; newDB.createObjectStore("tasks", { keyPath: "id", autoIncrement:true }); }; The msIndexedDB.open() method accepts two parameters: the name of the database to open and the version of the database to open. If a database with a matching version already exists, then calling the msIndexedDB.open() method opens a connection to the existing database. If the database does not exist then the upgradeneeded event is raised. You handle the upgradeneeded event to create a new database. In the code above, the upgradeneeded event handler creates an object store named “tasks” (An object store roughly corresponds to a database table). When you add items to the tasks object store then each item gets an id property with an auto-incremented value automatically. The code above also includes an error event handler. If the IndexedDB database cannot be opened or created, for whatever reason, then an error message is written to the Visual Studio JavaScript Console window. Displaying a List of Tasks The TaskList application retrieves its list of tasks from the tasks object store, which we created above, and displays the list of tasks in a ListView control. Here is how the ListView control is declared: <div id="tasksListView" data-win-control="WinJS.UI.ListView" data-win-options="{ itemDataSource: TaskList.tasks.dataSource, itemTemplate: select('#taskTemplate'), tapBehavior: 'toggleSelect', selectionMode: 'multi', layout: { type: WinJS.UI.ListLayout } }"> </div> The ListView control is bound to the TaskList.tasks.dataSource data source. The TaskList.tasks.dataSource is created with the following code: // Create the data source var tasks = new WinJS.Binding.List(); // Open the database var db; var req = window.msIndexedDB.open("TasksDB", 1); req.onerror = function () { console.log("Could not open database"); }; req.onupgradeneeded = function (evt) { var newDB = evt.target.result; newDB.createObjectStore("tasks", { keyPath: "id", autoIncrement:true }); }; // Load the data source with data from the database req.onsuccess = function () { db = req.result; var tran = db.transaction("tasks"); tran.objectStore("tasks").openCursor().onsuccess = function(event) { var cursor = event.target.result; tasks.dataSource.beginEdits(); if (cursor) { tasks.dataSource.insertAtEnd(null, cursor.value); cursor.continue(); } else { tasks.dataSource.endEdits(); }; }; }; // Expose the data source and functions WinJS.Namespace.define("TaskList", { tasks: tasks }); Notice the success event handler. This handler is called when a database is successfully opened/created. In the code above, all of the items from the tasks object store are retrieved into a cursor and added to a WinJS.Binding.List object named tasks. Because the ListView control is bound to the WinJS.Binding.List object, copying the tasks from the object store into the WinJS.Binding.List object causes the tasks to appear in the ListView: Adding a New Task You add a new task in the Task List application by entering the title of a new task into an HTML form and clicking the Add button. Here’s the markup for creating the form: <form id="addTaskForm"> <input id="newTaskTitle" title="New Task" required /> <button>Add</button> </form> Notice that the INPUT element includes a required attribute. In a Metro application, you can take advantage of HTML5 Validation to validate form fields. If you don’t enter a value for the newTaskTitle field then the following validation error message is displayed: For a brief introduction to HTML5 validation, see my previous blog entry: http://stephenwalther.com/blog/archive/2012/03/13/html5-form-validation.aspx When you click the Add button, the form is submitted and the form submit event is raised. The following code is executed in the default.js file: // Handle Add Task document.getElementById("addTaskForm").addEventListener("submit", function (evt) { evt.preventDefault(); var newTaskTitle = document.getElementById("newTaskTitle"); TaskList.addTask({ title: newTaskTitle.value }); newTaskTitle.value = ""; }); The code above retrieves the title of the new task and calls the addTask() method in the tasks.js file. Here’s the code for the addTask() method which is responsible for actually adding the new task to the IndexedDB database: // Add a new task function addTask(taskToAdd) { var transaction = db.transaction("tasks", IDBTransaction.READ_WRITE); var addRequest = transaction.objectStore("tasks").add(taskToAdd); addRequest.onsuccess = function (evt) { taskToAdd.id = evt.target.result; tasks.dataSource.insertAtEnd(null, taskToAdd); } } The code above does two things. First, it adds the new task to the tasks object store in the IndexedDB database. Second, it adds the new task to the data source bound to the ListView. The dataSource.insertAtEnd() method is called to add the new task to the data source so the new task will appear in the ListView (with a nice little animation). Deleting Existing Tasks The Task List application enables you to select one or more tasks by clicking or tapping on one or more tasks in the ListView. When you click the Delete button, the selected tasks are removed from both the IndexedDB database and the ListView. For example, in the following screenshot, two tasks are selected. The selected tasks appear with a teal background and a checkmark: When you click the Delete button, the following code in the default.js file is executed: // Handle Delete Tasks document.getElementById("btnDeleteTasks").addEventListener("click", function (evt) { tasksListView.winControl.selection.getItems().then(function(items) { items.forEach(function (item) { TaskList.deleteTask(item); }); }); }); The selected tasks are retrieved with the TaskList selection.getItem() method. In the code above, the deleteTask() method is called for each of the selected tasks. Here’s the code for the deleteTask() method: // Delete an existing task function deleteTask(listViewItem) { // Database key != ListView key var dbKey = listViewItem.data.id; var listViewKey = listViewItem.key; // Remove item from db and, if success, remove item from ListView var transaction = db.transaction("tasks", IDBTransaction.READ_WRITE); var deleteRequest = transaction.objectStore("tasks").delete(dbKey); deleteRequest.onsuccess = function () { tasks.dataSource.remove(listViewKey); } } This code does two things: it deletes the existing task from the database and removes the existing task from the ListView. In both cases, the right task is removed by using the key associated with the task. However, the task key is different in the case of the database and in the case of the ListView. In the case of the database, the task key is the value of the task id property. In the case of the ListView, on the other hand, the task key is auto-generated by the ListView. When the task is removed from the ListView, an animation is used to collapse the tasks which appear above and below the task which was removed.

  • Magento, NGINX, PHP-FPM, APC, MEMCACHED, 16gb Ram CentOS, Spiking PHP-FPM to 100% CPU

    - by Terry Dunford
    I have been trying to resolve my issue of spiking cpu caused by php-fpm processes. I've reduced the php-fpm config settings to: pm = ondemand pm.max_children = 12 pm.start_servers = 2 pm.min_spare_servers = 2 pm.max_spare_servers = 10 pm.max_requests = 500 php_admin_value[memory_limit] = 128M Problem still exists. I'm running a Joomla main site (which is having no problems) and a Magento store in a sub-directory. My server is a Linux CentOS, running NGINX, APC, Memcached, Full Page Cache and php-fpm. My server has 8 cores and 16gb dedicated ram. My host has shut down my server several times the past week because my php-fpm processes are consuming the entire network. A lot of the individual php-fpm processes are getting over 50% cpu. I've hired several "professionals" and none of them was able to help me, so now broke and stumped, I'm turning to you guys for help. So any suggestions would be greatly appreciated. I turned on slow php logs and here are some of the latest results: [01-Apr-2012 14:26:12] [pool magento] pid 21537 script_filename = /home/flyfish/www/flyshop/index.php [0x0000000011a394f8]

  • RFC 1918 address on open internet?

    - by longneck
    In trying to diagnose a failover problem with my Cisco ASA 5520 firewalls, I ran a traceroute to www.btfl.com and, much to my surprise, some of the hops came back as RFC 1918 addresses. Just to be clear, this host is not behind my firewall and there is no VPN involved. I have to connect across the open internet to get there.

  • Sql Server 2008 Create Foreign Key Manually

    - by tgriffiths
    I have inherited an old database which wasn't designed very well. It is a Sql Server 2008 database which is missing quite a lot of Foreign Key relationships. Below shows two of the tables, and I am trying to manually create a FK relationship between dbo.app_status.status_id and dbo.app_additional_info.application_id I am using SQL Server Management Studio when trying to create the relationship using the query below USE myDatabase; GO ALTER TABLE dbo.app_additional_info ADD CONSTRAINT FK_AddInfo_AppStatus FOREIGN KEY (application_id) REFERENCES dbo.app_status (status_id) ON DELETE CASCADE ON UPDATE CASCADE ; GO However, I receive this error when I run the query The ALTER TABLE statement conflicted with the FOREIGN KEY constraint "FK_AddInfo_AppStatus". The conflict occurred in database "myDatabase", table "dbo.app_status", column 'status_id'. I am wondering if the query is failing because each table already contains approximately 130,000 records? Please help. Thanks.

  • Dropping duplicate|redundant Unique Constraint from FILESTREAM table

    - by electricsk8
    I have a table with a FILESTREAM column, and it has two unique constraints specified for the same FILESTREAM column, ie: ALTER TABLE [dbo].[TableName] ADD CONSTRAINT [UQ_TableName_33C4988760FC61CA] UNIQUE NONCLUSTERED ([GUID_Column]); GO ALTER TABLE [dbo].[TableName] ADD CONSTRAINT [UQ_TableName_33C49887145C0A3F] UNIQUE NONCLUSTERED ([GUID_Column]); GO I'd like to drop one of the unique constraints, as they are duplicates. However, when I try and drop one of the two duplicate constraints, I receive the following error. "A table with FILESTREAM column(s) must have a non-NULL unique ROWGUID column." Anyone know how to remove one of the two constraints?

  • MySQL: how to convert many MyISAM tables to InnoDB in a production database?

    - by Continuation
    We have a production database that is made up entirely of MyISAM tables. We are considering converting them to InnoDB to gain better concurrency & reliability. Can I just alter the myISAM tables to InnoDB without shutting down MySQL? What are the recommend procedures here? How long will such a conversion take? All the tables have a total size of about 700MB There are quite a large number of tables. Is there any way to apply ALTER TABLE to all the MyISAM tables at once instead of doing it one by one? Any pitfalls I need to be aware of? Thank you

When the user access it for the first time, the app executes this query to create all the database: CREATE TABLE `databases` ( `id` bigint(20) NOT NULL auto_increment, `driver` varchar(45) NOT NULL, `server` text NOT NULL, `user` text NOT NULL, `password` text NOT NULL, `database` varchar(200) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=2 ;

In some environments i get this error: SQLSTATE[HY000]: General error: 1005 Can't create table 'dms.databases' (errno: 150) I tried everything that I could find on Google but nothing works. The strange part is that if I run this query in PhpMyAdmin he creates my database, without any error.

  • Using SQL Developer to Debug your Anonymous PL/SQL Blocks

    - by JeffS
    Everyone knows that SQL Developer has a PL/SQL debugger – check! Everyone also knows that it’s only setup for debugging standalone PL/SQL objects like Functions, Procedures, and Packages, right? – NO! SQL Developer can also debug your Stored Java Procedures AND it can debug your standalone PLSQL blocks. These bits of PLSQL which do not live in the database are also known as ‘Anonymous Blocks.’ Anonymous PL/SQL blocks can be submitted to interactive tools such as SQL*Plus and Enterprise Manager, or embedded in an Oracle Precompiler or OCI program. At run time, the program sends these blocks to the Oracle database, where they are compiled and executed. Here’s an example of something you might want help debugging: Declare x number := 0; Begin Dbms_Output.Put(Sysdate || ' ' || Systimestamp); For Stuff In 1..100 Loop Dbms_Output.Put_Line('Stuff is equal to ' || Stuff || '.'); x := Stuff; End Loop; End; / With the power of remote debugging and unshared worksheets, we are going to be able to debug this ANON block! The trick – we need to create a dummy stored procedure and call it in our ANON block. Then we’re going to create an unshared worksheet and execute the script from there while the SQL Developer session is listening for remote debug connections. We step through the dummy procedure, and this takes OUT to our calling ANON block. Then we can use watches, breakpoints, and all that fancy debugger stuff! First things first, create this dummy procedure - create or replace procedure do_nothing is begin null; end; Then mouse-right-click on your Connection and select ‘Remote Debug.’ For an in-depth post on how to use the remote debugger, check out Barry’s excellent post on the subject. Open an unshared worksheet using Ctrl+Shift+N. This gives us a dedicated connection for our worksheet and any scripts or commands executed in it. Paste in your ANON block you want to debug. Add in a call to the dummy procedure above to the first line of your BEGIN block like so Begin do_nothing(); ... Then we need to setup the machine for remote debug for the session we have listening – basically we connect to SQL Developer. You can do that via a Environment Variable, or you can just add this line to your script - CALL DBMS_DEBUG_JDWP.CONNECT_TCP( 'localhost', '4000' ); Where ‘localhost’ is the machine where SQL Developer is running and ’4000′ is the port you started the debug listener on. Ok, with that all set, now just RUN the script. Once the PL/SQL call is made, the debugger will be invoked. You’ll end up in the DO_NOTHING() object. Debugging an ANON block from SQL Developer is possible! If you step out to the ANON block, we’ll end up in the script that’s used to call the procedure – which is the script you want to debug. The Anonymous Block is opened in a new SQL Dev page You can now step through the block, using watches and breakpoints as expected. I’m guessing your scripts are going to be a bit more complicated than mine, but this serves as a decent example to get you started. Here’s a screenshot of a watch and breakpoint defined in the anon block being debugged: Breakpoints, watches, and callstacks - oh my! For giggles, I created a breakpoint with a passcount of 90 for the FOR LOOP to see if it works. And of course it does You Might Also EnjoyUsing Pass Counts to Turbo Charge Your PL/SQL BreakpointsSQL Developer Tip: Viewing REFCURSOR OutputThe PL/SQL Debugger Strikes Back: Episode VDebugging PL/SQL with SQL Developer: Episode IVHow to find dependent objects in your PL/SQL Programs using SQL Developer
