  • Connection timed out on Node.js app running under CentOS

    - by ss1271
    I followed this tutorial to create a simple node.js app on my CentOS: the node.js version is: $ node -v v0.10.28 Here's my app.js: // Include http module, var http = require("http"), // And url module, which is very helpful in parsing request parameters. url = require("url"); // show message at console console.log('Node.js app is running.'); // Create the server. http.createServer(function (request, response) { request.resume(); // Attach listener on end event. request.on("end", function () { // Parse the request for arguments and store them in _get variable. // This function parses the url from request and returns object representation. var _get = url.parse(request.url, true).query; // Write headers to the response. response.writeHead(200, { 'Content-Type': 'text/plain' }); // Send data and end response. response.end('Here is your data: ' + _get['data']); }); // Listen on the 8080 port. }).listen(8080); However, when I uploaded this app onto my remote server (assume the address is 123.456.78.9), I couldn't get access to it on my browser http://123.456.78.9:8080/?data=123 The browser returned Error code: ERR_CONNECTION_TIMED_OUT. I tried the same app.js code which runs fine on my local machine, is there anything I am missing? I tried to ping the server and its address was reachable. Thanks.

  • Notepad++ tabbing out of tags, autocomplete

    - by Matt
    I'm trying to learn a little HTML. Everyone says to use Notepad++ over notepad. I have autocomplete on. My question: When I type my opening tag and Notepad++ then puts"""" closing tag, how do I "jump" out of the tag when I'm done typing? If I tab or hit enter, I'm still stuck before the closing tag. I can use my arrow keys, but if I'm going to do that, I would rather just type the closing tags. Also if I have an UL of 10 items, and I want to change it to an OL, how do I select both the opening and closing tags so I may edit them at the same time? Thanks PS I wasn't able to post the HTML tags.

  • use Amazon EC2 tools in Capistrano to get the servers to push the code

    - by APZ
    I am trying to use EC2 tools to get all the machines with a particular tag in some type of array in /config/deploy/prod.rb file in Capistrano. Something like this: In prod.rb file: //untested command workers-array[]=$(ec2-describe-instances -F vpc-id=1234 -F tag:Env=prod -F tag:SystemType=worker) for(i=0;i<workers-array.len;i++){ role :worker-A, workers-array[i] } I am not sure how we can do this in capistrano, am new to ruby too. Guys any help on this would be really appreciated.

  • Mutt: apply command to all tagged messages

    - by mrucci
    From the mutt manual: Once you have tagged the desired messages, you can use the tag-prefix operator, which is the ; (semicolon) key by default. When the tag-prefix operator is used, the next operation will be applied to all tagged messages if that operation can be used in that manner. But it seems that I can only execute commands that are already bound to a specific keyboard shortcut. For example I can use ;d to delete all selected messages. What if I want to apply an "unbound" command (such as purge-message)? I have also tried using something based on :exec tag-prefix or :push tag-prefix without success.

  • IIS8 Application request routing

    - by JustDanyul
    Sorry for what is most likely NOT a very intelligent question, but my non-sysadmin brain is struggling to understand what is causing my problem. Basically, I wan't to enable reverse proxying on a IIS8 box. I read though this article: http://www.iis.net/learn/extensions/url-rewrite-module/reverse-proxy-with-url-rewrite-v2-and-application-request-routing And I've installed the ARR extension from here: http://www.iis.net/downloads/microsoft/application-request-routing Now, I enabled the proxying (as explained in the MS tutorial), and I felt the other setting as they where (again, as instructed in the tutorial). My rule looks like the following <rule name="Reverse Proxy to payroll" stopProcessing="true"> <match url="^mytest/(.*)" /> <action type="Rewrite" url="http://localhost:8282/{R:1}" /> </rule> But alas, it doesn't work. If I change it to a "normal" rewrite rule, as in <rule name="Reverse Proxy to payroll" stopProcessing="true"> <match url="^mytest/(.*)" /> <action type="Rewrite" url="/{R:1}" /> </rule> Then it works. So, it must differently be something with the reverse proxy. Any idea what gives?

  • apt: how to search using package tags?

    - by depesz
    Some (most?) packages in Debian, have tags. For example: =# apt-cache show squirrelmail | perl -lne 'print if /^Tag:/.../^\S/' Tag: implemented-in::php, interface::web, mail::imap, mail::smtp, mail::user-agent, network::server, protocol::http, protocol::imap, protocol::smtp, role::program, scope::application, use::browsing, use::editing, use::searching, use::transmission, use::viewing, web::TODO, web::application, works-with::mail Section: web But, I can't find a way, to list all packages with given tag. Is it possible?

  • Is there any diff tool for XML files?

    - by qedi
    Are there any good (Linux) tools for diffing two XML files? Ideally, I would like to be able configure it to some things strict, or loosen some things, like whitespace, or attribute order. I'll often care that the files are functionally the same, but diff by itself, would be annoying to use, especially if the XML file doesn't have a lot of linebreaks. For example, the following should really be okay to me: <tag att1="one" att2="two"> content </tag> <tag att2="two" att1="one"> content </tag>

  • Regex syntax question - trying to understand

    - by Asaf Chertkoff
    i don't know if this question belong here or no, but it is worth a shot. i'm a self taught php programmer and i'm only now starting to grasp the regex stuff. i'm pretty aware of its capabilities when it is done right, but this is something i need to dive in too. so maybe someone can help me, and save me so hours of experiment. i have this string: here is the <a href="http://www.google.com" class="ttt" title="here"><img src="http://www.somewhere.com/1.png" alt="some' /></a> and there is <a href="#not">not</a> a chance... now, i need to perg_match this string and search for the a href tag that has an image in it, and replace it with the same tag with a small difference: after the title attribute inside the tag, i'll want to add a rel="here" attribute. of course, it should ignore links (a href's) that doesn't have img tag inside. help will be appreciated, thanks.

  • A mechanism to include site title in every page, but not in <title> element

    - by Saeed Neamati
    Each site can have a name. For example, site x. Each page also can have a name (or a title) that should appear in <title> tag in the header. However, many websites out there use the combination site name - page name to provide the value for <title> tag. I find it a little far from being semantic. On the other hand, if you only include page title in <title> tag, search engines won't find your site by its name. For example, if your site's name is Thought Results and you don't include it in page titles, then if you search for Thought Results, you won't find your site in SERPs. Thus I'm searching for a mechanism to both include site title (not page title) in every page, and also only include page title in <title> tag to get more semantic results. Is there any way to achieve this?

  • Better ways to have valuable data indexed, which is ignored currently

    - by Sam
    <a title="">.../a> Hi folks. It seems that my title tag which holds extremely valuable and describes contents on my simple design page is currently compeltely denied by search engines and not indexed at all!! Those descriptions should however be indexed as the describe valuable portions to an otherwise empty page with clean glossary (thats neat and organised to the eye of the viewer. So putting all that descriptive data into visible space would ruin the designish less is more fundamental... So, which alternatives to the title tag do I have, in order to put important contents that are relevant for both user as well as search engines? A <a name="">......</> B <p name="">......</> C <a alt="">.......</> D <p alt="">.......</> From the above list, arose my question: Which of the above is advisable alternative in order to get the valuable actual content indexed? Should it be in a a tag or p tag? Or are there even better tags for this which still keep layout clean? You suggestions are Much appreciated!

  • Gotcha when using JavaScript in ADF Regions

    - by Frank Nimphius
    You use the ADF Faces af:resource tag to add or reference JavaScript on a page. However, adding the af:resource tag to a page fragment my not produce the desired result if the script is added as shown below <?xml version='1.0' encoding='UTF-8'?> <jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1" xmlns:af="http://xmlns.oracle.com/adf/faces/rich"> <af:resource type="javascript">   function yourMethod(evt){ ... } </af:resource> Adding scripts to a page fragment like this will see the script added for the first page fragment loaded by an ADF region but not for any subsequent fragment navigated to within the context of task flow navigation. The cause of this problem is caching as the af:resource tag is a JSP element and not a lazy loaded JSF component, which makes it a candidate for caching. To solve the problem, move the af:resource tag into a container component like af:panelFormLayout so the script is added when the component is instantiated and added to the page.  <?xml version='1.0' encoding='UTF-8'?> <jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1" xmlns:af="http://xmlns.oracle.com/adf/faces/rich"> <af:panelFormLayout> <af:resource type="javascript">   function yourMethod(evt){ ... } </af:resource> </af:panelFormLayout> Magically this then works and prevents browser caching of the script when using page fragments.

  • Where should "display functions" live in an MVC web app?

    - by User
    I'm using the Yii Framework which is an MVC php framework that is pretty similar to your standard web-based MVC framework. I want to display the related data from a many-to-many table as a list of strings in my view. Assuming a table schema like: tag { id, name } post { id, title, content, date } post_tag { post_id, tag_id } A post will display like: Date: 9/27/2012 Title: Some Title Content: blah blah blah... Tags: Smart Funny Cool Informative I can achieve this by doing something like this in my Post view: <?php echo join(' ', array_map(function($tag) { return $tag->name; }, $model->tags)); ?> (where $model->tags is an array of Tag objects associated with my model) My questions are: Is this amount of code/logic okay in the view? (Personally I think I'd rather just reference a property or call a single function.) If not, where should this code live? In the model? the controller? a helper? Potentially I may want to use in in other views as well. Ultimately I think its purely a display issue which would make me think it should be in the view, but then I have to repeat the code in any view I want to use it in.

  • Best Terminology for a particular php-based site architecture? [closed]

    - by hen3ry
    For a site... o whose overall look-and-feel is generated by one php page ("index.php"). o in which "index.php" provides for all pages served the following required components: The DOCTYPE, opening html tag, the head section, the opening body tag, the end-body tag, and end-html tag. o which uses computed hierarchical navigation menus within "index.php" to offer visitors access to the site content. o in which all content is stored in individual files that contain "headerless html". (The DOCTYPE, etc. etc. being being provided by "index.php" as described above.) Q1: what term best describes this architecture? I'm seeking a concise descriptor that is useful in conversation and definitive as a search term, in whole-web searches, and searching here on Pro Webmasters. Q2: what term best describes the individual content files? Same general goals for the descriptor as above. As you see above, I couldn't avoid using the term "headerless html", my best choice. But this term does not seem to be in general use. I've found some people use this term to describe such as my content files, but others use it quite differently.

  • Why is MediaWiki auto-linking the word “files”

    - by dfrankow
    Our MediaWiki installation is auto-linking the word "files". So Here are some files: a, b, c would result in the word "files" being linked to http://ourhost/mediawiki/files. Why is that happening and how do I make it stop? I can use the nowiki tag, but perhaps it does not surprise you that the word "files" appears often, and it is aggravating to use that tag all the time.

  • Varnish configuration to only cache for non-logged in users

    - by davidsmalley
    I have a Ruby on Rails application fronted by varnish+nginx. As most of the sites content is static unless you are a logged in user, I want to cache the site heavily with varnish when a user is logged out but only to cache static assets when they are logged in. When a user is logged in they will have the cookie 'user_credentials' present in their Cookie: header, in addition I need to skip caching on /login and /sessions in order that a user can get their 'user_credentials' cookie in the first place. Rails by default does not set a cache friendly Cache-control header, but my application sets a "public,s-max-age=60" header when a user is not logged in. Nginx is set to return 'far future' expires headers for all static assets. The configuration I have at the moment is totally bypassing the cache for everything when logged in, including static assets — and is returning cache MISS for everything when logged out. I've spent hours going around in circles and here is my current default.vcl director rails_director round-robin { { .backend = { .host = "xxx.xxx.xxx.xxx"; .port = "http"; .probe = { .url = "/lbcheck/lbuptest"; .timeout = 0.3 s; .window = 8; .threshold = 3; } } } } sub vcl_recv { if (req.url ~ "^/login") { pipe; } if (req.url ~ "^/sessions") { pipe; } # The regex used here matches the standard rails cache buster urls # e.g. /images/an-image.png?1234567 if (req.url ~ "\.(css|js|jpg|jpeg|gif|ico|png)\??\d*$") { unset req.http.cookie; lookup; } else { if (req.http.cookie ~ "user_credentials") { pipe; } } # Only cache GET and HEAD requests if (req.request != "GET" && req.request != "HEAD") { pipe; } } sub vcl_fetch { if (req.url ~ "^/login") { pass; } if (req.url ~ "^/sessions") { pass; } if (req.http.cookie ~ "user_credentials") { pass; } else { unset req.http.Set-Cookie; } # cache CSS and JS files if (req.url ~ "\.(css|js|jpg|jpeg|gif|ico|png)\??\d*$") { unset req.http.Set-Cookie; } if (obj.status >=400 && obj.status <500) { error 404 "File not found"; } if (obj.status >=500 && obj.status <600) { error 503 "File is Temporarily Unavailable"; } } sub vcl_deliver { if (obj.hits > 0) { set resp.http.X-Cache = "HIT"; } else { set resp.http.X-Cache = "MISS"; } }

  • Linq-to-XML query to select specific sub-element based on additional criteria

    - by BrianLy
    My current LINQ query and example XML are below. What I'd like to do is select the primary email address from the email-addresses element into the User.Email property. The type element under the email-address element is set to primary when this is true. There may be more than one element under the email-addresses but only one will be marked primary. What is the simplest approach to take here? Current Linq Query (User.Email is currently empty): var users = from response in xdoc.Descendants("response") where response.Element("id") != null select new User { Id = (string)response.Element("id"), Name = (string)response.Element("full-name"), Email = (string)response.Element("email-addresses"), JobTitle = (string)response.Element("job-title"), NetworkId = (string)response.Element("network-id"), Type = (string)response.Element("type") }; Example XML: <?xml version="1.0" encoding="UTF-8"?> <response> <response> <contact> <phone-numbers/> <im> <provider></provider> <username></username> </im> <email-addresses> <email-address> <type>primary</type> <address>[email protected]</address> </email-address> </email-addresses> </contact> <job-title>Account Manager</job-title> <type>user</type> <expertise nil="true"></expertise> <summary nil="true"></summary> <kids-names nil="true"></kids-names> <location nil="true"></location> <guid nil="true"></guid> <timezone>Eastern Time (US &amp; Canada)</timezone> <network-name>Domain</network-name> <full-name>Alice</full-name> <network-id>79629</network-id> <stats> <followers>2</followers> <updates>4</updates> <following>3</following> </stats> <mugshot-url> https://assets3.yammer.com/images/no_photo_small.gif</mugshot-url> <previous-companies/> <birth-date></birth-date> <name>alice</name> <web-url>https://www.yammer.com/domain.com/users/alice</web-url> <interests nil="true"></interests> <state>active</state> <external-urls/> <url>https://www.yammer.com/api/v1/users/1089943</url> <network-domains> <network-domain>domain.com</network-domain> </network-domains> <id>1089943</id> <schools/> <hire-date nil="true"></hire-date> <significant-other nil="true"></significant-other> </response> <response> <contact> <phone-numbers/> <im> <provider></provider> <username></username> </im> <email-addresses> <email-address> <type>primary</type> <address>[email protected]</address> </email-address> </email-addresses> </contact> <job-title>Office Manager</job-title> <type>user</type> <expertise nil="true"></expertise> <summary nil="true"></summary> <kids-names nil="true"></kids-names> <location nil="true"></location> <guid nil="true"></guid> <timezone>Eastern Time (US &amp; Canada)</timezone> <network-name>Domain</network-name> <full-name>Bill</full-name> <network-id>79629</network-id> <stats> <followers>3</followers> <updates>1</updates> <following>1</following> </stats> <mugshot-url> https://assets3.yammer.com/images/no_photo_small.gif</mugshot-url> <previous-companies/> <birth-date></birth-date> <name>bill</name> <web-url>https://www.yammer.com/domain.com/users/bill</web-url> <interests nil="true"></interests> <state>active</state> <external-urls/> <url>https://www.yammer.com/api/v1/users/1089920</url> <network-domains> <network-domain>domain.com</network-domain> </network-domains> <id>1089920</id> <schools/> <hire-date nil="true"></hire-date> <significant-other nil="true"></significant-other> </response> </response>

  • OpenJPA + Tomcat JDBC Connection Pooling = stale data

    - by Julie MacNaught
    I am using the Tomcat JDBC Connection Pool with OpenJPA in a web application. The application does not see updated data. Specifically, another java application adds or removes records from the database, but the web application never sees these updates. This is quite a serious issue. I must be missing something basic. If I remove the Connection Pool from the implementation, the web application sees the updates. It's as if the web application's commits are never called on the Connection. Version info: Tomcat JDBC Connection Pool: org.apache.tomcat tomcat-jdbc 7.0.21 OpenJPA: org.apache.openjpa openjpa 2.0.1 Here is the code fragment that creates the DataSource (DataSourceHelper.findOrCreateDataSource method): PoolConfiguration props = new PoolProperties(); props.setUrl(URL); props.setDefaultAutoCommit(false); props.setDriverClassName(dd.getClass().getName()); props.setUsername(username); props.setPassword(pw); props.setJdbcInterceptors("org.apache.tomcat.jdbc.pool.interceptor.ConnectionState;"+ "org.apache.tomcat.jdbc.pool.interceptor.StatementFinalizer;"+ "org.apache.tomcat.jdbc.pool.interceptor.SlowQueryReportJmx;"+ "org.apache.tomcat.jdbc.pool.interceptor.ResetAbandonedTimer"); props.setLogAbandoned(true); props.setSuspectTimeout(120); props.setJmxEnabled(true); props.setInitialSize(2); props.setMaxActive(100); props.setTestOnBorrow(true); if (URL.toUpperCase().contains(DB2)) { props.setValidationQuery("VALUES (1)"); } else if (URL.toUpperCase().contains(MYSQL)) { props.setValidationQuery("SELECT 1"); props.setConnectionProperties("relaxAutoCommit=true"); } else if (URL.toUpperCase().contains(ORACLE)) { props.setValidationQuery("select 1 from dual"); } props.setValidationInterval(3000); dataSource = new DataSource(); dataSource.setPoolProperties(props); Here is the code that creates the EntityManagerFactory using the DataSource: //props contains the connection url, user name, and password DataSource dataSource = DataSourceHelper.findOrCreateDataSource("DATAMGT", URL, username, password); props.put("openjpa.ConnectionFactory", dataSource); emFactory = (OpenJPAEntityManagerFactory) Persistence.createEntityManagerFactory("DATAMGT", props); If I comment out the DataSource like so, then it works. Note that OpenJPA has enough information in the props to configure the connection without using the DataSource. //props contains the connection url, user name, and password //DataSource dataSource = DataSourceHelper.findOrCreateDataSource("DATAMGT", URL, username, password); //props.put("openjpa.ConnectionFactory", dataSource); emFactory = (OpenJPAEntityManagerFactory) Persistence.createEntityManagerFactory("DATAMGT", props); So somehow, the combination of OpenJPA and the Connection Pool is not working correctly.
