  • Daily, Weekly and Monthly Page View Counter

    - by Jens Fahnenbruck
    I'm building a website with user generated content. On the home page I want to show a list of all created items, and I want to be able to sort them by a view counter. That's sound easy, but I want multiple counters. I want to know which was the most visited item in the last day, last week or last months or overall. My first Idea was to create 4 counter columns in the item's DB-Table. One for each of daily, weekly, monthly and overall, and the create a cron job, that clears the daily counter every 24 hours, the weekly counter every 7 days and so on. But my problem with this is, what happens if I want to know which was the most viewed item of the week, just after the weekly counter got cleared? What I need is an efficient way to create a continous counter, which got reduced for every page view that is too old, and increased for every new page view. Right now I'm thinking of a solution with the redis server, but I have no solution yet. I'm just looking for a general idea here, but FYI I'm developing this application in Ruby on Rails.

  • Action Mailer Confirmation Emails - Ruby on Rails...

    - by bgadoci
    I have successfully installed the Clearance Gem from ThoughtBot. Clearance sends a confirmation email upon a new sign_up and suggests adding: config.action_mailer.default_url_options = { :host => 'localhost:3000' } to your /environments/test.rb and development.rb. I have tried this and also config.action_mailer.default_url_options = { :host => '127.0.0.1', :port => 3000 } But can't seem to get rails to send the email. As I am new to both Ruby and Rails, I am wondering if there is some step/config that ThoughtBot is assuming I have already done to send emails. What am I doing wrong/missing? UPDATE: Just added notifier.rb class Notifier < ActionMailer::Base recipients recipient.email_address_with_name bcc ["[email protected]"] from "[email protected]" subject "New account information" body :account => recipient end end

  • Good way to capture/replay sessions from Apache Log?

    - by Mark Harrison
    For performance testing, I would like to capture some traffic from a production server and use that as a basis to replay the request to a test server in order to simulate a realistic load in our development environment. These are all stateless queries, so no issues regarding cookies, sessions, etc. The Apache log timestamps everything down to a 1 second resolution, but that's not fine enough granularity for our peak times. What's the best way to capture more fine-grained timestamps for replay? And is there some ab-like load generating program that can use this data to replicate load?

  • What is the iPad user agent?

    - by Yoric
    Now that the iPad craze is officially open, it's time to think websites also for the iPad. From what I gather, the iPad is using iPhone OS, but with a different screen resolution from the iPhone/iPod touch. So suddenly, the assumption that iPhone OS = iPhone screen resolution becomes false. Sounds like many sites may have to revise their user-agent - css mapping. So, can anyone with access to the iPad or the iPad SDK give us the user-agent string? Thanks in advance.

  • System.ArgumentException: Invalid hex character at DecryptAssemblyResource

    - by Radu094
    My webapp is trowing these exceptions intermitently ever since we migrated to Mono + Apache: The error sounds more like a problem reading/processing some assembly, so I was wondering if I should be worried that there might be a problem with the hard-drive?

  • How Can I Find Out *HOW* My Site Was Hacked? How Do I Find Site Vulnerabilities?

    - by Imageree
    One of my custom developed ASP.NET sites was hacked today: "Hacked By Swan (Please Stop Wars !.. )" It is using ASP.NET and SQL Server 2005 and IIS 6.0 and Windows 2003 server. I am not using Ajax and I think I am using stored procedures everywhere I am connecting to the database so I dont think it is SQL injection. I have now removed the write permission on the folders. How can I find out what they did to hack the site and what to do to prevent it from happening again? The server is up to date with all Windows updates. What they have done is uploading 6 files (index.asp, index.html, index.htm,...) to the main directory for the website. What log files should I upload? I have log files for IIS from this folder: c:\winnt\system32\LogFiles\W3SVC1. I am willing to show it to some of you but don't think it is good to post on the Internet. Anyone willing to take a look at it? I have already searched on Google but the only thing I find there are other sites that have been hacked - I haven't been able to see any discussion about it. I know this is not strictly related to programming but this is still an important thing for programmers and a lot of programmers have been hacked like this.

  • How to go about reading a web page lazily in Clojure

    - by Rayne
    I and a friend recently implemented link grabbing in my Clojure IRC bot. When it sees a link, it slurp*s the page and grabs the title from the page. The problem is that it has to slurp* the ENTIRE page just to grab the link. How does one go about reading a page lazily until the first ?

  • Why are there so many data centres in Texas?

    - by jklp
    I've been searching for online hosting recently and have noticed a high concentration of hosting providers in Texas. Just wondering why this is? It couldn't be possibly be because of temperature (I don't think Texas is a particularly cool place to be) or maybe power is cheaper in Texas vs the rest of the States? Or maybe it's just there are laws in place which give hosting providers tax breaks? Would be very interested to find out.

  • Cladogram, tree of life, cladistics, taxonomy in JS or canvas?

    - by boblet
    Good people - I need some help to find a way to create an interactive cladogram or phylogenetic tree (yes, I have read all related posts, and do not find what I am looking for). The thing is, I need the nodes to be name-able. An example would be something like this Most scripts I find are either applets, flash, or simply do not show the node classification, ie it would skip "feliformia" in this example. This is useless to me, as I would then end up with carnivore - anonymous node - anonymous node - anonymous node - tiger, and that is not good. This tree will in theory cover all life, so it could get rather large, and get links and names in english and latin from database. So: no flash, no applets. It must be horizontal, no supertrees (circular). I have gone through this http://bioinfo.unice.fr/biodiv/Tree_editors.html but most of them seems to be either old, not displaying sub-node levels, applets, or way too complex. I imagine this would be a delightful job for canvas/jQuery..? And chances are, someone got there before me? Any pointers much appreciated. Note: if anyone out there would like to do something like this as a project, I will be happy to help, even though it would not benefit me for this project.This type of taxonomy is not as simple as it may seem, and I would be happy see this happen.

  • CrossPage PostBack in series of web pages

    - by Vishnu Reddy
    I had a requirement to pass data between pages in my application. I have a Page A where user will input some data and on submit User will be redirected to Page B where again user will enter some more data and on submitting user will be show a confirmation in Page C after doing some calculations and data saving. Following is the idea I was trying to use: PageA.aspx: <form id="frmPageA" runat="server"> <p>Name: <asp:TextBox ID="txtName" runat="server"></asp:TextBox></p> <p>Age: <asp:TextBox ID="txtAge" runat="server"></asp:TextBox></p> <p><asp:Button ID="btnPostToPageB" runat="server" Text="Post To PageB" PostBackUrl="~/PageB.aspx" /></p> </form> In Page A Codebehind file I am creating following public properties of the inputs to access in Page B: public string Name { get { return txtName.Text.ToString(); } } public int Age { get { return Convert.ToInt32(txtAge.Text); } } In PageB.aspx: using previouspage directive to access page A public properties <%@ PreviousPageType VirtualPath="~/PageA.aspx" % <form id="frmPageB" runat="server"> <asp:HiddenField ID="hfName" runat="server" /> <asp:HiddenField ID="hfAge" runat="server" /> <p><asp:RadioButtonList ID="rblGender" runat="server" TextAlign="Right" RepeatDirection="Horizontal"> <asp:ListItem Value="Female">Female</asp:ListItem> <asp:ListItem Value="Male">Male</asp:ListItem> </asp:RadioButtonList></p> <p><asp:Button ID="btnPostToPageC" runat="server" Text="Post To PageC" PostBackUrl="~/PageC.aspx" /></p> </form> In Page B Codebehind file I am creating following public properties for the inputs to access in Page C: public RadioButtonList Gender { get { return rblGender; } } public string Name { get { return _name; } } public int Age { get { return _age; } } //checking if data is posted from Page A otherwise redirecting User to Page A protected void Page_Load(object sender, EventArgs e) { if (PreviousPage != null && PreviousPage.IsCrossPagePostBack && PreviousPage.IsValid) { hfName.Value = PreviousPage.Name; hfAge.Value = PreviousPage.Age.ToString(); } else Response.Redirect("PageA.aspx"); }` in PageC.aspx: using previouspage directive to access page A public properties <%@ PreviousPageType VirtualPath="~/PageB.aspx" % <form id="frmPageC" runat="server"> <p>Name: <asp:Label ID="lblName" runat="server"></asp:Label></p> <p>Age: <asp:Label ID="lblAge" runat="server"></asp:Label></p> <p>Gender: <asp:Label ID="lblGender" runat="server"></asp:Label></p> <p><asp:Button ID="btnBack" runat="server" Text="Back" PostBackUrl="~/PageA.aspx" /></p> </form> Page C code behind file: if (PreviousPage != null && PreviousPage.IsCrossPagePostBack && PreviousPage.IsValid) { lblName.Text = PreviousPage.Name.ToString(); lblAge.Text = PreviousPage.Age.ToString(); lblGender.Text = PreviousPage.Gender.SelectedValue.ToString(); } else Response.Redirect("PageA.aspx");

  • Slow Jquery Animation

    - by Pyronaut
    I have this webpage : http://miloarc.pyrogenicmedia.com/ Which atm is nothing special. It has a few effects but none that break the bank. If you mouse over a tile, it should change it's opacity to give it a fade effect. This is done through the Jquery Animation, not through CSS (I do this so it can fade, instead of being a straight change). Everything looks nice when the page loads, and the fades look perfect. Infact if you drag your mouse all over the place, if gives you a "trail" almost like a snake. Anyway, My next problem is that you will see there is a box in the top left, which is going to tell you information about the tile you are hovering over. This seems to work fine. When you mouse over that information box, it switches it's position (So that you can reach the tiles that were previously hidden underneath it). From my understanding, this is all working fine, and to the letter. However, After one move of the info box (One hover). Viewing the page in Firefox turns slugish. As in, after a successful move of the info box, the fade effects become very stuttered, and it doesn't pick up events as fast meaning you can't draw a "trail" on the screen. Chrome doesn't have this issue. It seems to work fine no matter what. Safari also seems ok. Although I do notice if I move my mouse really fast, it does jump a bit but not as much as firefox. Internet explorer doesn't work at all. Seems to crash the browser... And there is an error with the rounded corner plugin im using (Not sure why...). All in all, I think whatever I'm doing inside my code must be heavily sluggish. But I don't know where it is happening. Here is the full code, but I would advise go to the link to view everything. <script type="text/javascript"> $(document).ready(function() { var WindowWidth = $(window).width(); var WindowMod = WindowWidth % 20; var WindowWidth = WindowWidth - WindowMod; var BoxDimension = WindowWidth / 20; var BoxDimensionFixed = BoxDimension - 12; var dimensions = BoxDimensionFixed + 'px'; $('.gamebutton').each(function(i) { $(this).css('width', dimensions); $(this).css('height', dimensions); }); var OuterDivHeight = BoxDimension * 10; var TopMargin = ($(window).height() - OuterDivHeight) / 2; var OuterDivWidth = BoxDimension * 20; var LeftMargin = ($(window).width() - OuterDivWidth) / 2; $('#gamePort').css('margin-top', TopMargin).css('margin-left', LeftMargin).css('margin-right', LeftMargin); $('.gamebutton img').each(function(i) { $(this).hover( function () { $(this).animate({'opacity': 0.65}); }, function () { $(this).animate({'opacity': 1}); } ); }); $('.rounded').corners(); $('.gamebutton').each(function(i) { $(this).hover(function() { $('.gameTitlePopup').html($(this).attr('title')); FadeActive(); }); }); function FadeActive() { $('.activeInfo').fadeIn('slow'); } $('#gameInfoLeft').hover(function() { $(this).removeClass('activeInfo'); $(this).fadeOut('slow', function() { $('#gameInfoRight').addClass('activeInfo'); FadeActive(); }); }); $('#gameInfoRight').hover(function() { $(this).removeClass('activeInfo'); $(this).fadeOut('slow', function() { $('#gameInfoLeft').addClass('activeInfo'); FadeActive(); }); }); }); </script> Thanks for any help :).

  • Ruler to measure in browser (firefox)

    - by danke
    I'm looking for a good ruler to use to measure distances in a browser. I use Firefox. Any good suggestions that are currently being used by other developers. I have firebug, but I don't think it has a ruler. Does it? I would think a ruler would have made it to firebug, but there doesn't seem to be one, or I'm not looking in the right location. Thanks

  • Scalable Ticketing / Festival Website

    - by Luke Lowrey
    I've noticed major music festivals (at least in Australia) and other events that experience a peak in traffic when tickets go on sale have huge problems keeping their websites running well. I've seen a few different techniques used to try combat this such as short sessions and virtual queues but they dont seem to have much effect. If you were to design a website to sell a lot of tickets in a short amount of time how would you handle scalability? What technologies and programming techniques would you use?

  • Facebook Connect: with no javascript?

    - by nafe
    Is it possible to write a website that uses Facebook connect without JavaScript? I have a site set up that works great using XFBML but this (obviously) fails when I visit with JavaScript disabled. I have a feeling that this is possible using the REST-api for Facebook but I'd still appreciate some pointers. There was a discussion about this on the Facebook forum.

  • Google Visualization API - Line and Scatter on one Chart.

    - by ealgestorm
    Does any one know if it is possible to use the Default Google Scatter Chart in the Google Visualizations Gallery to draw a scatter chart that has both a series with points only, a series with a line of best fit and on top of this a set of lines across the chart indicating limits. i.e. at +/- 20% etc. The chart we need is actually a Control Chart with multiple series and individual formatting of each series displayed on the chart. i.e some series with only points other series with a line of best fit. Does any one know of a Control Chart that has already been done using the Google Visualization API?

  • WinMo > ASMX WebException - how to get details?

    - by eidylon
    Okay, we've got an application which consists of a website hosting several ASMX webservices, and a handheld application running on WinMo 6.1 which calls the webservices. Been developing in the office, everything works perfect. Now we've gone to install it at the client's and we got all the servers set up and the handhelds installed. However the handhelds are now no longer able to connect to the webservice. I added in extra code in my error handler to specifically trap WebException exceptions and handle them differently in the logging to put out extra information (.Status and .Response). I am getting out the status, which is returning a [7], or ProtocolError. However when I try to read out the ResponseStream (using WebException.Response.GetResponseStream), it is returning a stream with CanRead set to False, and I thus am unable to get any further details of what is going wrong. So I guess there are two things I am asking for help with... a) Any help with trying to get more information out of the WebException? b) What could be causing a ProtocolError exception? Things get extra complicated by the fact that the client has a full-blown log-in-enabled proxy setup going on-site. This was stopping all access to the website initially, even from a browser. So we entered in the login details in the network connection for HTTP on the WinMo device. Now it can get to websites fine. In fact, I can even pull up the webservice fine and call the methods from the browser (PocketIE). So I know the device is able to see the webservices okay via HTTP. But when trying to call them from the .NET app, it throws ProtocolError [7]. Here is my code which is logging the exception and failing to read out the Response from the WebException. Public Sub LogEx(ByVal ex As Exception) Try Dim fn As String = Path.Combine(ini.CorePath, "error.log") Dim t = File.AppendText(fn) t.AutoFlush = True t.WriteLine(<s>===== <%= Format(GetDateTime(), "MM/dd/yyyy HH:mm:ss") %> =====<%= vbCrLf %><%= ex.Message %></s>.Value) t.WriteLine() t.WriteLine(ex.ToString) t.WriteLine() If TypeOf ex Is WebException Then With CType(ex, WebException) t.WriteLine("STATUS: " & .Status.ToString & " (" & Val(.Status) & ")") t.WriteLine("RESPONSE:" & vbCrLf & StreamToString(.Response.GetResponseStream())) End With End If t.WriteLine("=".Repeat(50)) t.WriteLine() t.Close() Catch ix As Exception : Alert(ix) : End Try End Sub Private Function StreamToString(ByVal s As IO.Stream) As String If s Is Nothing Then Return "No response found." // THIS IS THE CASE BEING EXECUTED If Not s.CanRead Then Return "Unreadable response found." Dim rv As String = String.Empty, bytes As Long, buffer(4096) As Byte Using mem As New MemoryStream() Do While True bytes = s.Read(buffer, 0, buffer.Length) mem.Write(buffer, 0, bytes) If bytes = 0 Then Exit Do Loop mem.Position = 0 ReDim buffer(mem.Length) mem.Read(buffer, 0, mem.Length) mem.Seek(0, SeekOrigin.Begin) rv = New StreamReader(mem).ReadToEnd() mem.Close() End Using Return rv.NullOf("Empty response found.") End Function Thanks in advance!
