  • Is it possible to create a service like Feed My Inbox on my own server?

    - by Mark Bowen
    I was just wondering if it's at all possible to create a service like Feed My Inbox on my own server using PHP? Basically I have a site which has RSS feeds which are dynamic in nature and can search from thousands of posts based on many different criteria. I have the RSS feed working fine and bringing back data dynamically for whatever criteria I want so that bits fine. I am using the ExpressionEngine CMS to handle the site and there will be thousands of users on the site (currently there are around 2,0000) but that number is exponentially growing every single day. What I want to be able to do is allow the users to choose from certain criteria which will then build a dynamic RSS URL which will then be stored in a database table (one row for each user). This bit I will be able to do myself but then I want to be able to send out new RSS feed items via e-mail to each user. This is the part I'm a little stuck on. I'm guessing I would somehow need to run a cron job to hit a page which would check each users RSS feed and then if there are new items to send them to the user via e-mail. That's where I am totally stuck though and I'm just wondering what the best way to go about it would be? That or any software in PHP that already does this sort of thing would be great. I tried out phpList but it has severe problems working with RSS and I only ever got it to work once and now never again and I've read that lots of people have had this same problem so unfortunately it's not just me :-( I know there are services such as Feed My Inbox which I could easily set up so that users click a link and their RSS feed URL is added to go and use that service but I want to keep users from seeing the dynamic nature of the feed or they will easily be able to modify it to get at other items in the feed. I need this so that I can charge for access to the feeds but if people can see the URL of the feed then I will be totally unstuck as they will be able to get at whatever they want very easily. Therefore I'd like to be able to send the items out to them. Would really love to hear if anyone knows if this kind of thing is possible at all and what would be involved?

  • Binding value for NSTableView, but tooltip gets set as well

    - by Mark
    I've set up an NSTableView in Interface Builder to be populated from an NSArray. Each value of the array represents one row in the table. The value is bound correctly, but as a side effect, the table cell's tooltip is set to the string representation of the bound object. In my case, the NSArray contains NSDictiorany objects and the tooltip looks like it could be the [... description] output of that dictionary. Very ugly... I don't want the tooltip to be set at all. I have other tables that have plain NSString values bound to them and they don't have a tooltip set automatically. Is there some Interface Builder magic going on? I tried to start with a blank project - same problem. I should add that the table cell is a custom implementation of NSTextFieldCell that uses an NSButtonCell instance to draw an image and a label into the table. The values are retrieved from the dictionary bound as value. Why is the tooltip set when I only bind the "value" attribute? Thanks in advance!

  • Pros and Cons of oursql [closed]

    - by S.Mark
    According to this python page, oursql looks very cool. oursql has real parameterization. oursql allows text or binary data to be streamed into the database and streamed out of the database, instead of requiring everything to be buffered in the client. oursql can both insert rows lazily and fetch rows lazily. oursql has unicode support on by default. So, Anyone start using it in the live projects and could share pros and cons over it?

  • WCF Async callback setup for polled device

    - by Mark Pim
    I have a WCF service setup to control a USB fingerprint reader from our .Net applications. This works fine and I can ask it to enroll users and so on. The reader allows identification (it tells you that a particular user has presented their finger, as opposed to asking it to verify that a particular user's finger is present), but the device must be constantly polled while in identification mode for its status - when a user is detected the status changes. What I want is for an interested application to notify the service that it wants to know when a user is identified, and provide a callback that gets triggered when this happens. The WCF service will return immediately and spawn a thread in the background to continuously poll the device. This polling could go on for hours at a time if no one tries to log in. What's the best way to acheive this? My service contract is currently defined as follows: [ServiceContract (CallbackContract=typeof(IBiometricCallback))] public interface IBiometricWcfService { ... [OperationContract (IsOneWay = true)] void BeginIdentification(); ... } public interface IBiometricCallback { ... [OperationContract(IsOneWay = true)] void IdentificationFinished(int aUserId, string aMessage, bool aSuccess); ... } In my BeginIdentification() method can I easily spawn a worker thread to poll the device, or is it easier to make the WCF service asynchronous?

  • Algorithm for assigning a unique series of bits for each user?

    - by Mark
    The problem seems simple at first: just assign an id and represent that in binary. The issue arises because the user is capable of changing as many 0 bits to a 1 bit. To clarify, the hash could go from 0011 to 0111 or 1111 but never 1010. Each bit has an equal chance of being changed and is independent of other changes. What would you have to store in order to go from hash - user assuming a low percentage of bit tampering by the user? I also assume failure in some cases so the correct solution should have an acceptable error rate. I would an estimate the maximum number of bits tampered with would be about 30% of the total set. I guess the acceptable error rate would depend on the number of hashes needed and the number of bits being set per hash. I'm worried with enough manipulation the id can not be reconstructed from the hash. The question I am asking I guess is what safe guards or unique positioning systems can I use to ensure this happens.

  • Select distinct users with referrals

    - by Mark
    I have a bunch of Users. Since Django doesn't really let me extend the default User model, they each have Profiles. The Profiles have a referred_by field (a FK to User). I'm trying to get a list of Users with = 1 referral. Here's what I've got so far Profile.objects.filter(referred_by__isnull=False).values_list('referred_by', flat=True) Which gives me a list of IDs of the users who have referrals... but I need it to be distinct, and I want the User object, not their ID. Or better yet, it would be nice if it could return the number of referrals a user has. Any ideas?

    I'm using multiple cores in SOLR to enable offline population of indices (and then using SWAP to swap out the active core). I want to use the same solrconfig.xml file for both cores - can someone tell me where I should put this so it can be picked up by SOLR?

  • paintComponent on JPanel, image flashes and then disappears

    - by mark
    I have a JApplet (MainClass extends JApplet), a JPanel (ChartWindow extends JPanel) and a Grafico class. The problem is that the Grafico class instance has 2 JPanel that should show 2 images (1 for each panel) but the images are shown and after a little while they disappears: instead of them i get a gray background (like an empty JPanel). This happens for every repaint() call (that are made in the ChartWindow class) the MainClass init() contains chartwindow=new ChartWindow(); add(chartwindow) chartwindow has a Grafico instance. it's the ChartWindow's paintComponent (override) paintComponent(Graphics g) { super.paintComponent(g); Image immagineGrafico=createImage(grafico.pannelloGrafico.getWidth() ,grafico.pannelloGrafico.getHeight()); Image immagineVolumi=createImage(grafico.pannelloVolumi.getWidth() ,grafico.pannelloVolumi.getHeight()); Graphics2D imgGrafico=(Graphics2D)immagineGrafico.getGraphics(); Graphics2D imgVolumi=(Graphics2D)immagineVolumi.getGraphics(); grafico.draw(imgGrafico,imgVolumi,mouseX,mouseY); ((Graphics2D)grafico.pannelloGrafico.getGraphics()).drawImage(immagineGrafico,0,0,this); ((Graphics2D)grafico.pannelloVolumi.getGraphics()).drawImage(immagineVolumi,0,0,this); } grafico's JPanels are added this way in the ChartWindow's constructor grafico=new Grafico() ................ add(grafico.pannelloGrafico); add(grafico.pannelloVolumi); Tell me if you need more information, thank you very much :-)

  • My UITableView has duplicated rows

    - by Mark
    Im not sure why, but my UITableView, which isnt anything fancy, is showing repeating rows when it shouldnt be. It seems that the rows that get added when the user scrolls (i.e. the rows that are off the screen to start with) are getting the data for the wrong row index. Its almost like when a new cell is de-queued, it's using a cell that 'was' used, but wasn't cleaned up correctly. Do you need to 'clean up' cells that are de-queue so that new cells dont use cells that are already created? my code is as below: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CustomCellIdentifier = @"CustomCellIdentifier"; MyDayCell *cell = (MyDayCell *)[tableView dequeueReusableCellWithIdentifier: CustomCellIdentifier]; if (cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"MyDayCell" owner:self options:nil]; for (id oneObject in nib) if ([oneObject isKindOfClass:[MyDayCell class]]) cell = (MyDayCell *)oneObject; } NSUInteger section = [indexPath section]; NSUInteger row = [indexPath row]; NSArray *thisSectionItems = (NSArray*)[self.listData objectForKey: [[NSNumber alloc] initWithInt:section]]; MyDayDetails *rowData = [thisSectionItems objectAtIndex:row]; //setup my cells data here... return cell; } Is there anything wrong with this code? has anyone seen anything like this before?

  • asp.net and Visual studio root directory question

    - by Mark Kadlec
    I am seeing something very odd and thought I would ask the Stackoverflow community if they knew the answer. I have an asp.net project that runs fine in one environment, but couldn't figure out what happened to the styles in another environment. In the first environment (Windows 2008 Server), the following link worked fine: <link href="/Styles/09/style.css" rel="stylesheet" type="text/css" /> but in the other environment (it's a Windows 7), I had to change it to work: <link href="../Styles/09/style.css" rel="stylesheet" type="text/css" /> Notice that the directories seemed to shift ahead one directory in the Win7, what's going on? It's like the "running" directory seems now be the \bin directory instead of the home! Which environment is configured correctly? How do I determine execution directory level? My concern going forward is pushing to a prod environment and guessing which configuration is correct. Any insight would be appreciated!

  • Does anyone know of a free tool to integrate Reflector with Visual Studio, besides TestDriven.NET?

    - by mark
    Dear ladies and sirs. I love the Go to Reflector menu option installed by TD.NET. However, TD.NET is not free for commercial use and so I do not have it at work. I am wondering if there is another tool out there that does just that - allows to jump to Reflector from the source code in VS and which is totally free. I know it is possible to develop a VS add-in that does it, but, alas, I have no time for it, so if anyone has already developed something like this - feel free to share. Regards,

  • What garbage collection algorithms do all 5 major browsers use?

    - by Martin Wittemann
    I am currently rethinking the object dispose handling of the qooxdoo JavaScript framework. Have a look at the following diagram (A is currently in scope): Let's say we want to delete B. Generally, we cut all reference between all objects. This means we cut connection 1 to 5 in the example. Is this really necessary? As far as I have read hear 1, browsers use the mark-and-sweep algorithm. In that case, we just need to cut reference 1 (connection to the scope) and 5 (connection to the DOM) which could be much faster. But can I be sure that all browsers use the mark-and-sweep algorithm or something similar? 1 http://stackoverflow.com/questions/864516/what-is-javascript-garbage-collection

  • Using the MongoDB Ruby driver in Rails? (without an object mapper)

    - by Mark L

  • ASP.NET MVC: How does one add authentication to RSS Feeds?

    - by Mark Redman
    I have seen a few examples of how to create RSS feeds using ASP.NET MVC, either by creating an Action or through an HttpHandler. I need to authenticate feeds and am wondering how this is to be done (and supported by RSS readers rather than just browsing to the page/xml through a browser) and how would authentications differ between an MVC Action or HttpHandler?

  • How do I UPDATE a Linked Server table where "alias" is required, in SQL Server 2000?

    - by Mark Hurd
    In SQL Server 2005 tablename can be used to distinguish which table you're referring to: UPDATE LinkedServer.database.user.tablename SET val=u.val FROM localtable u WHERE tablename.ID=u.ID In SQL Server 2000 this results in Server: Msg 107, Level 16, State 2 The column prefix 'tablename' does not match with a table name or alias name used in the query. Trying UPDATE LinkedServer.database.user.tablename SET val=u.val FROM localtable u WHERE LinkedServer.database.user.tablename.ID=u.ID results in Server: Msg 117, Level 15, State 2 The number name 'LinkedServer.database.user.tablename' contains more than the maximum number of prefixes. The maximum is 3. And, of course, UPDATE LinkedServer.database.user.tablename SET val=u.val FROM localtable u WHERE ID=u.ID results in Server: Msg 209, Level 16, State 1 Ambiguous column name 'ID'. (In fact searching on "The number name contains more than the maximum number of prefixes. The maximum is 3." I found the answer, but I've typed up this question and I'm going to post it! :-) )

  • Can I use PayPal to charge a Credit Card automatically?

    - by Mark
    If I have a Visa card number saved in my database, is there a way I can charge that Visa automatically through the PayPal API without the user having to enter anything? We want to keep this site as easy and hassle-free to use as possible. It would be a variable amount, based on how they use the site. (Don't worry, proper disclaimers will be in place, and the user will be notified) What about these "recurring payments"? That way I don't have to store the CC info on my website, but do they allow variable amounts that I could periodically send to PayPal?
