  • Real-time stock market application

    - by Sam
    I'm an amateur programmer. I'd like to develop a software application (like Tradestation), to analyse real-time market data. Please teach me if the following approach is correct, ie the procedures, knowledge or software needed etc: Use a DB to read the real-time feed from data provider: what should be the right DB to use? I know it should be a time serious one. Can I use SQL, Mysql, or others? What database can receive real-time data feed? Do I need to configure the DB to do this? If the real-time data is in ASCII form, how can it be converted to those that can be read by the DB and my application? Should I have to write codes or just use some add-ins? What kind of add-in are needed? How should I code the program to retrieve the changing data from the DB so that the analysis software screen data can also change asynchronously? (like the RTD in excel) Which aspects of programming do I need to learn to develop the above? Are there web resources/ books I can refer to for more information?

  • Tools for managing eCommerce backend

    - by rboarman
    I am working with an eCommerce company that has outgrown their hacked together backend for managing inventory, pricing and feeds to various shopping engines (Yahoo, 3d cart, Amazon, etc.). They currently manage about 12,000 skus and are doing $40M in revenue. Their internal people are working on a new Magento solution, but that is six months away and they need to replace/improve their current solution in order to hold them over. Their current solution was developed by two people who have left the company. What tools/architecture do other eCommerce sites use to manage their inventory, pricing, product descriptions and feed generation for the shopping engines? The current solution looks like this: 1) Inventory, pricing and product descriptions are maintained in a database and in NetSuite by employees 2) New products are added to the database via import 3) Twice a week data is extracted into a giant Excel spreadsheet 4) The Excel file adjusts pricing based on some simple algorithms 5) The Excel file exports about six different csv feeds which are manually uploaded to Amazon, 3d cart, Yahoo, Google and Merchant Advantage a. Each feed is a variant of the product which different field names and formatting b. Pricing levels differ between feeds c. Some products are not sent to all feeds 6) Orders are manually parsed and the inventory is adjusted as needed once product is sold The new solution should: 1) Import data from ODBC, CSV and NetSuite (CSV via ftp) 2) Apply pricing changes via simple algorithms (< $80 add $10, $200 add $25) 3) Ensure margins are being met 4) Format and generate a bunch of CSV and XML feeds 5) Perhaps upload feeds to shopping engines automatically What I need to do is replace the Excel file with something that is maintainable and automated. Something in the .Net stack is preferable but not mandatory. I’ve been looking at BizTalk but it may take too long to develop and deploy. Any suggestions?

  • How to handle Real Time Data from a database perspective?

    - by balexandre
    I have an idea in mind, but it still confuses me the database area. Imagine that I want to show real time data, and using one of the latest browser technologies (web sockets - even using older browsers) it is very easy to show to all observables (user browser) what everyone is doing. Remy Sharp has an example about the simplicity about this. But I still don't get the database part, how would I feed, let's imagine (using Remy game Tron) that I want to save the path for each connected user in a database and if a client wants to see what is going on with a 5 sec delay, he will see that, not only the 5 sec until that moment but the continuation in time ... how can I query a DB like that? SELECT x, y FROM run WHERE time >= DATEADD(second, -5, rundate); is not the recommended path right? and pulling this x in x time ... this is not real data feed correct? If can someone help me understand the Database point of view, I would greatly appreciate.

  • Are the only types of data "sources" static and dynamic?

    - by blunders
    Thinking that there might be others, but not sure -- but before getting into that, let me explain what I mean by static and dynamic data sources. Static (or datastore) - Meaning that the data's state is non-changing, and if was changed, that would be a new state, and the old data would be considered stateless; meaning it no longer is known to exist, or not exist. Another way of possibly looking at a static data source might be that if read and written back without modification, the checksum for before and after should be exactly the same regardless of the duration of time between the reading and rewriting of the data. Examples: Photos, Files, Database Record, Dynamic (or datastream) - Meaning that the data's state is known to be in flux, and never expected to be the same per input. Example: Live video/audio feed, Stock Market feed, First let me say, the above is a very loose mapping of the concepts, and I'd welcome any feedback. Next, onto the core of the question, that being are these the only two types of data sources. My guess, is that yes, they are -- but that there are hybrid versions of the two. That being, streaming data that has a fixed state. For example, the data being streamed has a checksum given and each unique checksum is known to be a single instance of static data. On the flip side, static data could be chained via say a version control system; when played back, each version might be viewed as a segment of a stream; thing is, the very fact that it can be played back makes the data source static. Another type might be that the data source is being organically discovered, and it's simply unknown what the state is. Questions, feedback, requests -- just comment, thanks!!

  • How to choose how to store data?

    - by Eldros
    Give a man a fish and you feed him for a day. Teach a man to fish and you feed him for a lifetime. - Chinese Proverb I could ask what kind of data storage I should use for my actual project, but I want to learn to fish, so I don't need to ask for a fish each time I begin a new project. So, until I used two methods to store data on my non-game project: XML files, and relational databases. I know that there is also other kind of database, of the NoSQL kind. However I wouldn't know if there is more choice available to me, or how to choose in the first place, aside arbitrary picking one. So the question is the following: How should I choose the kind of data storage for a game project? And I would be interested on the following criterion when choosing: The size of the project. The platform targeted by the game. The complexity of the data structure. Added Portability of data amongst many project. Added How often should the data be accessed Added Multiple type of data for a same application Any other point you think is of interest when deciding what to use. EDIT I know about Would it be better to use XML/JSON/Text or a database to store game content?, but thought it didn't address exactly my point. Now if I am wrong, I would gladely be shown the error in my ways.

  • How can I handle an empty namespace with XDocument.XPathEvaluate?

    - by Kevin
    I'm trying to use XDocument and XPathEvaluate to get values from the woot.com feed. I'm handling other namespaces fine, but this example is giving me problems. <rss xmlns:a10="http://www.w3.org/2005/Atom" version="2.0"> <channel> <category text="Comedy" xmlns="http://www.itunes.com/dtds/podcast-1.0.dtd"> </category> <!-- this is a problem node, notice 'xmlns=' --!> So I try this: XmlNamespaceManager man = new XmlNamespaceManager(nt); man.AddNamespace("ns", "http://www.w3.org/2000/xmlns/"); // i've also tried man.AddNamespace("ns", string.Empty); xDocument.Namespace = man; var val = xDocument.XPathEvaluate("/rss/channel/ns:category/@text", xdwn.Namespace); val is always null. I'm using ns: from the suggestion from VS 2010 XPath Navigator plugin. Any thoughts on how to handle this?

  • Async actions inside Silverlight Method - returning the value

    - by tyndall
    What is the proper way to call an Async framework component - wait for an answer and then return the value. AKA contain the entire request/response in a single method. Example code: public class Experiment { public Experiment() { } public string GetSomeString() { WebClient wc = new WebClient(); wc.DownloadStringCompleted += new DownloadStringCompletedEventHandler(wc_DownloadStringCompleted); Uri u = new Uri("http://news.google.com/news?pz=1&cf=all&ned=us&hl=en&topic=t&output=rss"); wc.DownloadStringAsync(u); return "the news RSS from Google"; } private void wc_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e) { //don't really see how this callback method makes it able // to return the answer I'm looking for on the return // statement in the method above. } } MORE INFO: The reason I'm asking this that I have a project I'm working on where I'd like JavaScript code in the browser to use Silverlight like a Facade/Proxy to Web services and complex calculations & operations. I'd like to make the calls to the [ScriptableMembers] in Silvelight synchronously. I don't want Silverlight to callback into the browser's JavaScript

  • How to add a weather info to be evalueated only once???

    - by Savvas Sopiadis
    Hi everybody! In a ASP.MVC (1.0) project i managed to get weather info from a RSS feed and to show it up. The problem i have is performance: i have put a RenderAction() Method in the Site.Master file (which works perfectly) but i 'm worried about how it will behave if a user clicks on menu point 1, after some seconds on menu point 2, after some seconds on menu point 3, .... thus making the RSS feed requesting new info again and again and again! Can this somehow be avoided? (to somehow load this info only once?) Thanks in advance!

  • Create xml file to be used in wordpress post import

    - by adedoy
    Alright here is the thing, I have this site that was once wordpress but have been converted into 70+ static pages, the admin is deleted and the whole site is static(which means every page is in index.html), I want to create a script that makes an xml so that I will just have to import it in the new wordpress install. So far, I am able to create an XML but it only imports one post. The data source is the URL of a page and I use jquery $get to filter only to gather the post of a given archive. //html <input type="text" class="full_path"> <input type="button" value="Get Data" class="getdata"> //script $('.getdata').click(function(){ $.get($('.full_path').val(), function(data) { post = $(data).find('div [style*="width:530px;"]'); $('.result').html(post.html()); }); });//get Data Through AJAX I send the cleaned data into a php below that creates the XML: $file = 'newpost.xml'; $post_data = $_REQUEST['post_data']; // Open the file to get existing content $current = file_get_contents($file); // Append a new post to the file $catStr = ''; if(isset($post_data['categories']) && count($post_data['categories']) > 0){ foreach($post_data['categories'] as $category) { $catStr .= '<category domain="category" nicename="'.$category.'"><![CDATA['.$category.']]></category>'; } } $tagStr = ''; if(isset($post_data['tags']) && count($post_data['tags']) > 0){ foreach($post_data['tags'] as $tag) { $tagStr = '<category domain="post_tag" nicename="'.$tag.'"><![CDATA['.$tag.']]></category>'; } } $post_name = str_replace(' ','-',$post_data["title"]); $post_name = str_replace(array('"','/',':','.',',','[',']','“','”'),'',strtolower($post_name)); $post_date = '2011-4-0'.rand(1, 29).''.rand(1, 12).':'.rand(1, 59).':'.rand(1, 59); $pubTime = rand(1, 12).':'.rand(1, 59).':'.rand(1, 59).' +0000'; $post = ' <item> <title>'.$post_data["title"].'</title> <link>'.$post_data["link"].'</link> <pubDate>'.$post_data["date"].'

  • Simulating a cookie-enabled browser in PHP

    - by Itamar Benzaken
    How can I open a web-page and receive its cookies using PHP? The motivation: I am trying to use feed43 to create an RSS feed from the non-RSS-enabled HighLearn website (remote learning website). I found the web-page that contains the feed contents I need to parse, however, it requires to login first. Luckily, logging in can be done via a GET request so it's as easy as fopen()ing "http://highlearn.website/login_page.asp?userID=foo&password=bar" for example. But I still need to get the cookies generated when I logged in, pass the cookies to the real client (using setcookie() maybe?) and then redirect.

  • Dealing with HTTP content in HTTPS pages

    - by El Yobo
    We have a site which is accessed entirely over HTTPS, but sometimes display external content which is HTTP (images from RSS feeds, mainly). The vast majority of our users are also stuck on IE6. I would both of the following Prevent the IE warning message about insecure content Present something useful to users in place of the images that they can't otherwise see; if there was some JS I could run to figure out which images haven't been loaded and replace them with an image of ours instead that would be great. I suspect that the first aim is simply not possible, but the second may be sufficient. A worst case scenario is that I parse the RSS feeds when we import them, grab the images store them locally so that the users can access them that way, but it seems like a lot of pain for reasonably little gain.

  • Getting users latest tweet with Django

    - by Hanpan
    I want to create a function which grabs every users latest tweet from a specific group. So, if a user is in the 'authors' group, I want to grab their latest tweet and then finally cache the result for the day so we only do the crazy leg work once. def latest_tweets(self): g = Group.objects.get(name='author') users = [] for u in g.user_set.all(): acc = u.get_profile().twitter_account users.append('http://twitter.com/statuses/user_timeline/'+acc+'.rss') return users Is where I am at so far, but I'm at a complete loose end as to how I parse the RSS to get there latest tweet. Can anyone help me out here? If there is a better way to do this, any suggestions are welcome! I'm sure someone will suggest using django-twitter or other such libraries, but I'd like to do this manually if possible. Cheers

  • Django equivalent to paster for backend processes

    - by intractelicious
    I use pylons in my job, but I'm new to django. I'm making an rss filtering application, and so I'd like to have two backend processes that run on a schedule: one to crawl rss feeds for each user, and another to determine relevance of individual posts relative to users' past preferences. In pylons, I'd just write paster commands to update the db with that data. Is there an equivalent in django? EG is there a way to run the equivalent of python manage.py shell in a non-interactive mode?

  • In CakePHP, how to leave all prefixes?

    - by Victor Piousbox
    I have a link that goes like this: $this->Html->link('Welcome', array('controller' => 'users', 'action' => 'add')); I suspect it doesn't work (Firefox says the redirect will never complete), so I did this: $this->Html->link('Welcome', array('controller' => 'users', 'action' => 'add', 'my'=>false)); 'my' is a prefix. I also have 'admin', 'ajax', and 'rss'. So now instead of pointing to /users/add or /my/users/add, the link points to /rss/users/add. The link is in a header, in a layout so I don't know which prefix it will be invoked from. I want to go to /users/add, that is, leave all prefixes altogether. How do I do that in CakePHP? I'm using 1.3 version.

  • How to notify ViewController on parse end with multiple ViewControllers using a single parser.

    - by objneodude
    Hello, I have created a RSS parser and 3 TableViews and it parses the RSS files fine but I don't know how to notify the TableViewController when parsing has ended so it can update the view. The TableViewController initiates the parser and the parsing of a feed. parser = [[RSSParser alloc] initWithURL:@"http://randomfeed.com"]; I can access the single feed items like [parser feedItems]; In parser.m i have implemented the delegate methods of NSXMLParser: - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName - (void)parserDidEndDocument:(NSXMLParser *)parser So how do i get parserDidEndDocument to notify my controllers so i can add the data to the tableview. Cheers from a obj-c beginner.

    Hello, I am trying to read rss feed of Yahoo but i am unable to make it work properly. The code is absolutely correct , i am sure about it. It works sometimes but sometimes i get UnknownHostException. What can be the reason? Is there some problem with my internet or something else? This is my code :- public List<RssFeed> getRssFeed() { try { List<RssFeed> objList = new ArrayList<RssFeed>(); DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); DocumentBuilder db = dbf.newDocumentBuilder(); Document doc = db.parse("http://rss.news.yahoo.com/rss/india"); //doc.getDocumentElement().normalize(); Element docElement = doc.getDocumentElement(); NodeList objChannelList = docElement.getChildNodes(); for (int intIndex = 0; intIndex < objChannelList.getLength(); intIndex++) { if (objChannelList.item(intIndex).getNodeType() == Node.ELEMENT_NODE) { Element elemItem = (Element) objChannelList.item(intIndex); NodeList itemList = elemItem.getElementsByTagName("item"); //show only 3 news int count = itemList.getLength() > 3 ? 3 : objChannelList.getLength(); for (int intSubIndex = 0; intSubIndex < count; intSubIndex++) { NodeList itemDetailList = itemList.item(intSubIndex).getChildNodes(); String strTitle = ((Node) itemDetailList.item(RSS_VALUES.TITLE.getValue())).getFirstChild().getNodeValue(); String strdescription = ((Node) itemDetailList.item(RSS_VALUES.DESCRIPTION.getValue())).getFirstChild().getNodeValue(); String strLink = ((Node) itemDetailList.item(RSS_VALUES.LINK.getValue())).getFirstChild().getNodeValue(); //System.out.println(strTitle + "\n" + strdescription + "\n" + strLink + "\n\n\n\n"); objList.add(new RssFeed(strTitle, strdescription, strLink)); } } } return objList; } catch (SAXException ex) { Logger.getLogger(Utils.class.getName()).log(Level.SEVERE, null, ex); } catch (IOException ex) { Logger.getLogger(Utils.class.getName()).log(Level.SEVERE, null, ex); } catch (ParserConfigurationException ex) { Logger.getLogger(Utils.class.getName()).log(Level.SEVERE, null, ex); } return null; } Thanks in advance :). This problem has been bugging me since 1 month. Don't know why does Java in this case behave as per its mood :(
