  • Nodejs for processing js and Nginx for handling everything else

    - by Kevin Parker
    I am having a nodejs running on port 8000 and nginx on port 80 on same server. I want Nginx to handle all the requests(image,css,etc) and forward js requests to nodejs server on port 8000. Is it possible to achieve this. i have configured nginx as reverse proxy but its forwarding every request to nodejs but i want nginx to process all except js. nginx/sites-enabled/default/ upstream nodejs { server localhost:8000; #nodejs } location / { proxy_pass http://192.168.2.21:8000; proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504; proxy_redirect off; proxy_buffering off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; }

  • Having Troubles Getting My Apache Server Online(NodeJS and Apache)

    - by Jeff Armingol
    I am new here. This is my situation. I am using nodejs modules, serialport2 and socket.io, because I am trying to forward the data from my arduino hardware through serialports. In my server side script, I read the data then forward it to the client side. Now I am using Apache to serve the html page,which is the client side. I am running Nodejs on port 8000 and Apache on port 80. It is running OKAY when I view it in my browser typing localhost:80. The data is appearing and seems fine. Now when I tried to get my Apache server online using a Free DDNS provider(http://www.noip.com/) and my port80, it loaded the webpage but there are no data appearing on the page. What seems to be the problem here? Really need your expertise and advice. Thanks in advanced!

  • Alternative to cPanel (For Email, ect)

    - by Dboy1612
    I'm currently setting up a VPS for the first time. Standard that I've ever worked with before on shared hosting was cPanel, but as the majority of my work I plan on doing from now on will be using NodeJS and Python/Flask, I'd like to avoid needing to install Apache/MySQL/PHP. What would be my best bet to help manage a mail server other than cPanel? Or even other specific server settings that may come in handy later? Plan on using Ubuntu if that counts for anything.

  • Defining an implementation independent version of the global object in JavaScript

    - by Aadit M Shah
    I'm trying to define the global object in JavaScript in a single line as follows: var global = this.global || this; The above statement is in the global scope. Hence in browsers the this pointer is an alias for the window object. Assuming that it's the first line of JavaScript to be executed in the context of the current web page, the value of global will always be the same as that of the this pointer or the window object. In CommonJS implementations, such as RingoJS and node.js the this pointer points to the current ModuleScope. However, we can access the global object through the property global defined on the ModuleScope. Hence we can access it via the this.global property. Hence this code snippet works in all browsers and in at least RingoJS and node.js, but I have not tested other CommomJS implementations. Thus I would like to know if this code will not yield correct results when run on any other CommonJS implementation, and if so how I may fix it. Eventually, I intend to use it in a lambda expression for my implementation independent JavaScript framework as follows (idea from jQuery): (function (global) { // javascript framework })(this.global || this);

  • Return value from Object match

    - by Hito_kun
    I'm, by no means, JS fluent, so forgive me if im asking for some really basic stuff, but I've not being able to find a proper answer to my question. Im writting my first Node.js (plus Extra Framework and Socket.io) app and Im having some fun setting up the server side of a FB-like messenger (surprise!!!). So, let's say I have this data structure to store online users(This is a JSON Array, but I'm not sure it is the best way to do it or should I go with Javascript Objects): [ { "site": 45, "users": [ { "idUser": 5, "idSocket": "qwe87r7w8qwe", "name": "Carlos Ray Norris" }, { "idUser": 6, "idSocket": "v8d9d0fgfs7d", "name": "John Connor" } ] }, { "site": 48, "users": [ { "idUser": 22, "idSocket": "qwe87r7w8qwe", "name": "David Bowie" }, { "idUser": 23, "idSocket": "v8d9d0fgfs7d", "name": "Barack H. Obama" } ] } ] What I want to do is to search in the array for x value given y. In this case, retrieving the idSocket knowing the idUser WITHOUT having to run through the array values. So I have basically 2 questions: first, what would be the proper way to store users online? and secondly, how to find values matching with the values I already know (find the idSocket that has a given idUser). I would like a pure JS approach(or using some of the tools given by Node, Socket.io or Express), but if that's not possible then I can look for some JQuery.

  • How do you parse with SAX using Attributes & Values to a URL path using iPhone SDK?

    - by Jim
    I'm trying to get my head around parsing with SAX and thought a good place to start was the TopSongs example found at the iPhone Dev Center. I get most of it but when it comes to reaching Attributes and Values within a node I can't find a good example anywhere. The XML has a path to a URL for the coverArt. And the XML node looks like this. <itms:coverArt height="60" width="60">http://a1.phobos.apple.com/us/r1000/026/Music/aa/aa/27/mzi.pbxnbfvw.60x60-50.jpg</itms:coverArt> What I've tried is this for the startElement… ((prefix != NULL && !strncmp((const char *)prefix, kName_Itms, kLength_Itms)) && (!strncmp((const char *)localname, kName_CoverArt, kLength_Item) && !strncmp((const char *)attributes, kAttributeName_CoverArt, kAttributeLength_CoverArt) && !strncmp((const char *)attributes, kValueName_CoverArt, kValueLength_CoverArt) || !strncmp((const char *)localname, kName_Artist, kLength_Artist) || and picking it up again with just the localname at the end like this. if (!strncmp((const char *)localname, kName_CoverArt, kLength_CoverArt)) { importer.currentSong.coverArt = [NSURL URLWithString:importer.currentString]; The trace is -[Song setCoverArt:]: unrecognized selector sent to instance.

  • Locating SSL certificate, key and CA on server

    - by jovan
    Disclaimer: you don't need to know Node to answer this question but it would help. I have a Node server and I need to make it work with HTTPS. As I researched around the internet, I found that I have to do something like this: var fs = require('fs'); var credentials = { key: fs.readFileSync('path/to/ssl/private-key'), cert: fs.readFileSync('path/to/ssl/cert'), ca: fs.readFileSync('path/to/something/called/CA') }; var app = require('https').createServer(credentials, handler); I have several problems with this. First off, all the examples I found use completely different approaches. Some link to .pem files for both the certificate and key. I don't know what pem files are but I know my certificate is .crt and my key is .key. Some start off at the root folder and some seem to just have these .pem files in the application directory. I don't. Some use the ca thing too and some don't. This CA is supposed to be my domain's CA bundle according to some articles - but none explain where to find this file. In the ssl directory on my server I have one .crt file in the certs directory and one .key file in the keys directory, in addition to an empty csrs directory and an ssl.db file. So, where do I find these 3 files (key, cert, ca) and how do I link to them correctly?

  • (closed) nodejs responding an image (via pipe and response.end()) leads into strange behaviour

    - by johannesboyne
    What the Problem was: I had 2 different writeStreams! If WriteStram#1 is closed, the second should be closed too and then it all should be piped... BUT node is asynchronious so while one has been closed, the other one hasn't. Even the stream.end() was called... well you always should wait for the close event! thx guys for your help! I am at my wit's end. I used this code to pipe an image to my clients: req.pipe(fs.createReadStream(__dirname+'/imgen/cached_images/' + link).pipe(res)) it does work but sometimes the image is not transferred completely. But no error is thrown neither on client side (browser) nor on server side (node.js). My second try was var img = fs.readFileSync(__dirname+'/imgen/cached_images/' + link); res.writeHead(200, { 'Content-Type' : 'image/png' }); res.end(img, 'binary'); but it leads to the same strange behaviour... Does anyone got a clue for me? Regards! (abstracted code...) var http = require('http'); http.createServer(function (req, res) { Imgen.generateNew( 'virtualtwins/www_leonardocampus_de/overview/28', 'www.leonardocampus.de', 'overview', '28', null, [], [], function (link) { fs.stat(__dirname+'/imgen/cached_images/' + link, function(err, file_info) { if (err) { console.log('err', err); } console.log('file info', file_info.size); res.writeHead(200, 'image/png'); fs.createReadStream(__dirname+'/imgen/cached_images/' + link).pipe(res); }); } ); }).listen(13337, '127.0.0.1'); Imgen.generateNew just creates a new file, saves it to the disk and gives back the path (link)

  • Relative XPath node selection with C# XmlDocument

    - by lox
    Imagine the following XML document: <root> <person_data> <person> <name>John</name> <age>35</age> </person> <person> <name>Jim</name> <age>50</age> </person> </person_data> <locations> <location> <name>John</name> <country>USA</country> </location> <location> <name>Jim</name> <country>Japan</country> </location> </locations> </root> I then select the person node for Jim: XmlNode personNode = doc.SelectSingleNode("//person[name = 'Jim']"); And now from this node with a single XPath select I would like to retrieve Jim's location node. Something like: XmlNode locationNode = personNode.SelectSingleNode("//location[name = {reference to personNode}/name]"); Since I am selecting based on the personNode it would be handy if I could reference it in the select. Is this possible?.. is the connection there? Sure I could put in a few extra lines of code and put the name into a variable and use this in the XPath string but that is not what I am asking.

  • SimpleXML - "Node no longer exists"

    - by SubZane
    Hi I'm trying to get the video data from this youtube playlist feed and add the interesting data to an array and use that later, but as you can see from the feed some videolinks are "dead" and that results in problems for my code. The error I get is "Node no longer exists" when I try to access $attrs['url']. I've tried for hours to find a way to check if the node exists before I access it but I have no luck. If anyone could help me to either parse the feed some other way with the same result or create a if-node-exists check that works I would be most happy. Thank you in advance $url = 'http://gdata.youtube.com/feeds/api/playlists/18A7E36C33EF4B5D?v=2'; $sxml = simplexml_load_file($url); $i = 0; $videoobj; foreach ($sxml->entry as $entry) { // get nodes in media: namespace for media information $media = $entry->children('http://search.yahoo.com/mrss/'); // get video player URL $attrs = $media->group->player->attributes(); $videoobj[$i]['url'] = $attrs['url']; // get video thumbnail $attrs = $media->group->thumbnail[0]->attributes(); $videoobj[$i]['thumb'] = $attrs['url']; $videoobj[$i]['title'] = $media->group->title; $i++; }

  • XML generation with java, trying to copy the whole node

    - by Pawel Mysior
    I've got an xml document that filled with people (parent node is "students", and there are 25+ "student" nodes). Each student looks like this: <student> <name></name> <surname></surname> <grades> <subject name=""> <small_grades></small_grades> <final_grade></final_grade> </subject> <subject name=""> <small_grades></small_grades> <final_grade></final_grade> </subject> </grades> <average></average> </student> Basically, what I want to do ('ve been asked to do) is to make a program that would get 3 students with the best average. While parsing the document and getting three best students isn't too difficult, the XML generation is a pain in the ass. Right now, what I'm doing is getting every single node from student and recreating it to a new file. Is there a way to copy the whole student node with everything that's in it? Regards, Paul

  • tikz: set appropriate x value for a node

    - by basweber
    This question resulted from the question here I want to produce a curly brace which spans some lines of text. The problem is that I have to align the x coordinate manually, which is not a clean solution. Currently I use \begin{frame}{Example} \begin{itemize} \item The long Issue 1 \tikz[remember picture] \node[coordinate,yshift=0.7em] (n1) {}; \\ spanning 2 lines \item Issue 2 \tikz[remember picture] \node[coordinate, xshift=1.597cm] (n2) {}; \item Issue 3 \end{itemize} \visible<2->{ \begin{tikzpicture}[overlay,remember picture] \draw[thick,decorate,decoration={brace,amplitude=5pt}] (n1) -- (n2) node[midway, right=4pt] {One and two are cool}; \end{tikzpicture} } % end visible \end{frame} which produces the desired result: The unsatisfying thing is, that I had to figure out the xshift value of 1.597cm by trial and error (more or less) Without xshift argument the result is: I guess there is an elegant way to avoid the explicit xshift value. The best way would it imho be to calculate the maximum x value of two nodes and use this, (as already suggested by Geoff) But it would already be very handy to be able to explicitly define the absolute xvalues of both nodes while keeping their current y values. This would avoid the fiddly procedure of adapting the third post decimal position to ensure that the brace looks vertical.

  • Get tag name and value of a given node using XMLReader, DOM, Xpath

    - by rossjha
    I need to query an xml document and then display specific tag values, e.g. forename, surname, group(dept), job_title. I'm using XMLReader as i may need to work with large XML files. I using DomXPath to filter the data, but i don't know how to retrieve the nodeName and value for each element. The code below only returns 'member' as the node name? Any help would be appreciated. <?php $reader = new XMLReader(); $reader->open('include/staff.xml'); while ($reader->read()){ switch($reader->nodeType){ case(XMLREADER::ELEMENT): if($reader->localName === 'staff'){ $node = $reader->expand(); $dom = new DomDocument(); $dom->formatOutput = true; $n = $dom->importNode($node, true); $dom->appendChild($n); $xp = new DomXpath($dom); $res = $xp->query("/staff/member[groups='HR']"); } } } echo $res->item(0)->nodeName; echo $res->item(0)->nodeValue; ?>

  • item-not-found(404) when trying to get a node using Smackx pubsub

    - by DustMason
    I'm trying to use the latest Smackx trunk to get and then subscribe to a pubsub node. However, openfire just sends me a back an error: item not found (404). I am instantiating the java objects from ColdFusion, so my code snippets might look funny but maybe someone will be able to tell me what I've forgotten. Here's how I create the node: ftype = createObject("java", "org.jivesoftware.smackx.pubsub.FormType"); cform = createObject("java", "org.jivesoftware.smackx.pubsub.ConfigureForm").init(ftype.submit); cform.setPersistentItems(true); cform.setDeliverPayloads(true); caccess = createObject("java", "org.jivesoftware.smackx.pubsub.AccessModel"); cform.setAccessModel(caccess.open); cpublish = createObject("java", "org.jivesoftware.smackx.pubsub.PublishModel"); cform.setPublishModel(cpublish.open); cform.setMaxItems(99); manager = createObject("java", "org.jivesoftware.smackx.pubsub.PubSubManager").init(XMPPConnection); myNode = manager.createNode("subber", cform); And here's how I am trying to get to it (in a different section of code): manager = createObject("java", "org.jivesoftware.smackx.pubsub.PubSubManager").init(XMPPConnection); myNode = manager.getNode("subber"); Immediately upon creating the node I seem to be able to publish to it like so: payload = createObject("java", "org.jivesoftware.smackx.pubsub.SimplePayload").init("book","pubsub:test:book","<book xmlns='pubsub:test:book'><title>Lord of the Rings</title></book>"); item = createObject("java", "org.jivesoftware.smackx.pubsub.Item").init(payload); myNode.publish(item); However, it is the getNode() call that is causing my code to error. I have verified that the nodes are being created by checking the DB used by my openfire server. I can see them in there, properly attributed as leaf nodes, etc. Any advice? Anyone else out there doing anything with XMPP and ColdFusion? I have had great success sending and receiving messages with CF and Smack just haven't had the pubsub working yet :) Thanks!

  • xml schema putting both sequence and all under one complexType node

    - by exiang
    Here is the xml file: <section> <number>1</number> <title>A Title goes here...</title> <code>TheCode</code> <element></element> <element></element> </section> In section node, there are number, title and code node. Their sequence must not be fixed. Then, there are multiple element under section node as well. The idea is to use the following schema: <xs:complexType name="Type-section"> <xs:all> <xs:element name="number" minOccurs="0"></xs:element> <xs:element name="code" minOccurs="1"></xs:element> <xs:element name="title" minOccurs="1"></xs:element> </xs:all> <xs:sequence> <xs:element maxOccurs="unbounded" name="element"></xs:element> </xs:sequence> </xs:complexType> But it is invalid. I just cant put "sequence" and "all" together in the same level. How can i fix it?

  • The XPath @root-node-position attribute info

    - by Igor Savinkin
    I couldn't find the @root-node-position XPath attribute info. Would you give me a link of where i can read about it? Is it XPath 2.0? The code (not mine) is ../preceding-sibling::div[1]/div[@root-node-position]/div applied to this HTML: <div class="left"> <div class='prod2'> <div class='name'>Dell Latitude D610-1.73 Laptop Wireless Computer </div>2 GHz Intel Pentium M, 1 GB DDR2 SDRAM, 40 GB </div> <div class='prod1'> <div class='name'>Samsung Chromebook (Wi-Fi, 11.6-Inch) </div>1.7 GHz, 2 GB DDR3 SDRAM, 16 GB </div> </div> <div class="right"> <div class='price2'>$239.95</div> <div class='price1 best'>$249.00</div> </div> Firstly i fetch a price text under class='right' with this query : //DIV[contains(@class,'best')] and then i apply the above mentioned XPath with @root-node-attribute under class='left' to retrieve the rest of the record info.

  • Measuring how "heavily linked" a node is in a graph

    - by Eduardo León
    I have posted this question at MathOverflow.com as well. I am no mathematician and English is not my first language, so please excuse me if my question is too stupid, it is poorly phrased, or both. I am developing a program that creates timetables. My timetable-creating algorithm, besides creating the timetable, also creates a graph whose nodes represent each class I have already programmed, and whose arcs represent which pairs of classes should not be programmed at the same time, even if they have to be reprogrammed. The more "heavily linked" a node is, the more inflexible its associated class is with respect to being reprogrammed. Sometimes, in the middle of the process, there will be no option but to reprogram a class that has already been programmed. I want my program to be able to choose a class that, if reprogrammed, affects the least possible number of other already-programmed classes. That would mean choosing a node in the graph that is "not very heavily linked", subject to some constraints with respect to which nodes can be chosen. EDIT: The question was... Do you know any algorithm that measures how "heavily linked" a node is?

  • How can I get a Node adjacent to a unique Node using Scala?

    - by pr1001
    I'm trying to parse an Apple plist file and I need to get an array Node within it. Unfortunately its only unique identifier is sibling Node right before it, <key>ProvisionedDevices</key>. Right now my best thoughts are to use Java's XPATH querying or Node.indexOf. Here is an example: <plist version="1.0"> <dict> <key>ApplicationIdentifierPrefix</key> <array> <string>RP8CBF4MRE</string> </array> <key>CreationDate</key> <date>2010-05-10T11:44:35Z</date> <key>DeveloperCertificates</key> <array> ... <key>ProvisionedDevices</key> <array> ... // I need the Nodes here </array> </dict> </plist> Thanks!

  • jQuery way to replace just a text node with a mix of HTML and text

    - by hippietrail
    In my web browser userscript project I need to replace just one text node without affecting the other HTML elements under the same parent node as the text. And I need to replace it with more than one node: <div id="target"> some text<img src="/image.png"> </div> Needs to become: <div id="target"> <a href="#">mixed</a> text <a href="#">and</a> HTML<img src="/image.png"> </div> I know jQuery doesn't have a whole lot of support for text nodes. I know I could use direct DOM calls instead of jQuery. And I know I could just do something like $('#target').html(my new stuff + stuff I don't want to change). What I'd like to ask the experts here is, Is there a most idiomatic jQuery way to do this?

  • How can a B-tree node be represented?

    - by chronodekar
    We're learning B-trees in class and have been asked to implement them in code. The teacher has left choice of programming language to us and I want to try and do it in C#. My problem is that the following structure is illegal in C#, unsafe struct BtreeNode { int key_num; // The number of keys in a node int[] key; // Array of keys bool leaf; // Is it a leaf node or not? BtreeNode*[] c; // Pointers to next nodes } Specifically, one is not allowed to create a pointer to point to the structure itself. Is there some work-around or alternate approach I could use? I'm fairly certain that there MUST be a way to do this within the managed code, but I can't figure it out. EDIT: Eric's answer pointed me in the right direction. Here's what I ended up using, class BtreeNode { public List<BtreeNode> children; // The child nodes public static int MinDeg; // The Minimum Degree of the tree public bool IsLeaf { get; set; } // Is the current node a leaf or not? public List<int> key; // The list of keys ... }

  • Unexpected behaviour when dynamically add node in HAproxy server

    - by Anand Soni
    I wanted to use HAProxy for my web app for load balancing purpose. I am trying to add a new rabbitmq node dynamically in HAProxy server using command : haproxy -p /var/run/haproxy.pid -sf $(cat /var/run/haproxy.pid). I am doing tcp connection mode with leastconn balance algorithm in load balancing. What is expected is when there is 3 connection in one rabbitmq, I add a new rabbit server in HAProxy server. so the next connection would pass to 2nd rabbitmq server which is not happening in my case. It distributes the connection in haphazardly manner. Here is my config file: defaults log global mode http option httplog option dontlognull retries 3 option redispatch maxconn 2000 contimeout 5000 clitimeout 5000 srvtimeout 5000 listen rabbitmq 0.0.0.0:5672 mode tcp stats enable balance leastconn option tcplog server rabbit01 xx.xx.xx.xx:5672 check server rabbit02 xx.xx.xx.xx:5672 check listen tomcatq 0.0.0.0:80 mode http stats enable balance roundrobin stats refresh 10s stats refresh 10s stats uri /lb?stats stats auth admin:admin option httplog What is the problem causing this behavior?

  • Help building maya render node spec

    - by Ak
    Hi there, I'm looking to build 4x Maya render slaves/nodes for a friend of mine when his project gets green lit. The project involves MentalRay and lots of glass. I'm unsure if the new i7's 9xx or 8xx with hyper threading will do any better than a core 2 quad of the same (or close enough) speed. Does hyper threading make a difference to Maya or is it more performance per core based? I'm sure he's prefer I'd build another render node than pay for a bleeding edge CPU that only adds fractionly more GHz. -- The rest of the spec so far: 4Gb - 8Gb ram 64 bit OS: Probably Windows 7 (I know Linux is free, but want to build something my friend can support himself as easily as he supports his own workstation) 1TB HDD to hold textures, Maya files and renders which will be copied to central storage later Mobo with on-board video, gigabit NIC 500 - 650 watt PSU Desktop case something like a: Cooler Master ATCS 840 The machines will sold afterwards if necessary. -- If anyone has had experience in Maya and has done any tests with the new CPUs vs. the older ones I'd really appreciate your input.

  • Intermittent unavailability of an instance in a failover cluster while a standby node is offline in

    - by Emil Fridriksson
    Hi everyone. I've got a small failover cluster that I run for the websites my company has. During a RAM upgrade of the standby server, our websites started to show errors about not being able to access the database server. I verified that the instance was indeed up and the server accessable via remote desktop. I also tried a SQL connection to it and it worked, but that might have been after it became available again. This happened on and off until we were able to roll back the hardware changes that were in progress on the standby server and we were able to bring it back up. There was nothing of interest in the SQL Server log, but there is a continous log for the whole duration of the problem, so there was no restart of the SQL Server service. The event viewer is of more interest, since it shows events relating to the heartbeat network card, but I don't know how that would affect the availability of the server, since the standby node is offline. I'd appreciate any help you can provide, it's not very redundant if the setup depends on the standby server being up. :) Here are the event logs from the time of the problem, I include all of them since I can't seem to see what could possibly be the cause of the problem.
