  • What is the best tool to achieve this API design?

    - by Jose Fernandez
    Our web app offers a service that allows a "Publisher" to create a website (we give them a CMS system) that is ready to provide this service to "Members" (think Shopify). We have some possible clients that wish to become "Publishers" but they already have existing websites (vbulletin, word press blog, etc) with their own user base. We wish to develop an API that would allow these "Publishers" to keep using their own websites, and embed our services into them. Our main business requirement is that once "Members" are logged into the "Publishers" existing system, they should be able to also access our website without having to log-in again OR have to create another account there. The process should be seamless to the "Member" and "Publishers" should not have to sync their user base with our system. We also want to use an existing API authentication/authorization system instead of creating our own (OAuth, OpenID, etc) What would be the best way to use OAuth to achieve this sigle-sign on design? If OAuth is not the best tool, is there any other one out there that fits our requirements?

  • How to get DayNames from language only in .NET

    - by ManniAT
    Assume that I only have a country code (en, de, fr) and I need to display the weekdays in this language. I know about RegionInfo and CultureInfo - but I can't find a solution. If I create a country info from (for an example) "en" I have no DateTime info in it. It would also be OK to just take the first matching Region. For an example en-US for en or de-DE for de. I don't know if there are differences in DayNames but I know there are some for the months. de-DE Februar - de-AT Feber -- anyhow I don't care. Event if it may be "a bit different" (to see Februar instead of Feber) - it is still German. And that's what I want to achive - get en an write Monday - get de and write Montag... Is there a way to create a region just from a language code?

    - by Sumant
    while working on osCommerce-3 i got the table structure for category & categories_description as CREATE TABLE IF NOT EXISTS `osc_categories` ( `categories_id` int(10) unsigned NOT NULL AUTO_INCREMENT, `categories_image` varchar(255) DEFAULT NULL, `parent_id` int(10) unsigned DEFAULT NULL, `sort_order` int(11) DEFAULT NULL, `date_added` datetime DEFAULT NULL, `last_modified` datetime DEFAULT NULL, PRIMARY KEY (`categories_id`), KEY `idx_categories_parent_id` (`parent_id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=5 ; CREATE TABLE IF NOT EXISTS `osc_categories_description` ( `categories_id` int(10) unsigned NOT NULL, `language_id` int(10) unsigned NOT NULL, `categories_name` varchar(255) NOT NULL, PRIMARY KEY (`categories_id`,`language_id`), KEY `idx_categories_desc_categories_id` (`categories_id`), KEY `idx_categories_desc_language_id` (`language_id`), KEY `idx_categories_desc_categories_name` (`categories_name`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; here i am not getting the meanning of indexing "idx_categories_desc_categories_id", "idx_categories_desc_language_id", "idx_categories_desc_categories_name" What is the use of this indexing.What does it mean?

  • Developing "Command Line" in .NET?

    - by Sergey Malyan
    Imagine a "search box" on the right top side of the UI Windows Application. When user types a desired action, a matching functionality is executed. Screen gets opened, or action gets performed. For example: user types "create" and intellisence offered next word options "client"/"product", user picks "client", and "Create New Client" screen opens up. So what I am looking for if there is a framework support for this. I assume that framework shall bind together text commands names, commands and show in intellisense. Same framework possibly could have been used in alternative "Command Line interface". I recall Microsoft had some recent framework that helps to setup "command Line Interface" environmental. It is hard to search on web for this keywords, so relying on intelligent help from you guys. Thanks in advance.

  • HP DL370 G6 expansion

    - by user72185
    Hi, we are running a HP DL370 server with 6 x 300 gb disks on RAID 5. Due to a Windows update causing our server to fail recently, we couldn't access the data. I now want to separate the data from the OS (Windows server 2008 r2) so that if anything like that happens again, we can route everyone through a separate server. I have seen these HP storageworks enclosures (msa70) and have a couple of questions: Can I just take out our 2.5 inch 10k SAS drives, install them in the new Storageworks NAS and hey presto we would be up and running? If I wanted to then add another drive (I think there are 25 bays), can I just insert a blank but identical drive and the RAID 5 would dynamically expand to incorporate the new drive. Many thanks Adrian

  • Getting the DirectShow VideoRender filter to respond to MediaType changes on its Input Pin?

    - by Jonathan Websdale
    Below is the code extract from my decoder transform filter which takes in data from my source filter which is taking RTP network data from an IP camera. The source filter, decode filter can dynamically respond to changes in the camera image dimensions since I need to handle resolution changes in the decode library. I've used the 'ReceiveConnection' method as described in the DirectShow help, passing the new MediaType data in the next sample. However, I can't get the Video Mixing Renderer to accept the resolution changes dynamically even though the renderer will render the different resolution if the graph is stopped and restarted. Can anyone point out what I need to do to get the renderer to handle dynamic resolution changes? HRESULT CDecoder::Receive(IMediaSample* pIn) { //Input data does not necessarily correspond one-to-one //with output frames, so we must override Receive instead //of Transform. HRESULT hr = S_OK; //Deliver input to library long cBytes = pIn->GetActualDataLength(); BYTE* pSrc; pIn->GetPointer(&pSrc); try { hr = m_codec.Decode(pSrc, cBytes, (hr == S_OK)?&tStart : NULL); } catch (...) { hr = E_UNEXPECTED; } if (FAILED(hr)) { if (theLog.enabled()){theLog.strm() << "Decoder Error " << hex << hr << dec << " - resetting input"; theLog.write();} //Force reset of decoder m_bReset = true; m_codec.ResetInput(); //We have handled the error -- don't pass upstream or the source may stop. return S_OK; } //Extract and deliver any decoded frames hr = DeliverDecodedFrames(); return hr; } HRESULT CDecoder::DeliverDecodedFrames() { HRESULT hr = S_OK; for (;;) { DecodedFrame frame; bool bFrame = m_codec.GetDecodedFrame(frame); if (!bFrame) { break; } CMediaType mtIn; CMediaType mtOut; GetMediaType( PINDIR_INPUT, &mtIn); GetMediaType( PINDIR_OUTPUT, &mtOut); //Get the output pin's current image resolution VIDEOINFOHEADER* pvi = (VIDEOINFOHEADER*)mtOut.Format(); if( pvi->bmiHeader.biWidth != m_cxInput || pvi->bmiHeader.biHeight != m_cyInput) { HRESULT hr = GetPin(PINDIR_OUTPUT)->GetConnected()->ReceiveConnection(GetPin(PINDIR_OUTPUT), &mtIn); if(SUCCEEDED(hr)) { SetMediaType(PINDIR_OUTPUT, &mtIn); } } IMediaSamplePtr pOut; hr = m_pOutput->GetDeliveryBuffer(&pOut, 0, 0, NULL); if (FAILED(hr)) { break; } AM_MEDIA_TYPE* pmt; if (pOut->GetMediaType(&pmt) == S_OK) { CMediaType mt(*pmt); DeleteMediaType(pmt); SetMediaType(PINDIR_OUTPUT, &mt); pOut->SetMediaType(&mt); } // crop, tramslate and deliver BYTE* pDest; pOut->GetPointer(&pDest); m_pConverter->Convert(frame.Width(), frame.Height(), frame.GetY(), frame.GetU(), frame.GetV(), pDest); pOut->SetActualDataLength(m_pOutput->CurrentMediaType().GetSampleSize()); pOut->SetSyncPoint(true); if (frame.HasTimestamp()) { REFERENCE_TIME tStart = frame.Timestamp(); REFERENCE_TIME tStop = tStart+1; pOut->SetTime(&tStart, &tStop); } m_pOutput->Deliver(pOut); } return hr; }

  • Can i make an installer for my delphi programme?

    - by Hendriksen123
    I have made a delphi programme, which consists of a .exe and two custom file types that i have made (called Data.data and variables.data) I want to create a programme / find a programme that would place a copy of the main .exe in a folder in the program folders of XP, along with the .data files, and then place a shortcut to the programme on the desktop (ideally it would also put a folder in the start menu - all programmes with the programme. I should probably also make an uninstaller as well, that would remove the desktop shortcut, and delete the files. Is there a free piece of software i can use to create this, or is there any way i could achieve this myself through delphi?

    Hi, I have a service contract with Message as shown below. [OperationContract] Message MyMethodWithMessage(Message myMsgParam); Everything works fine. I could host my services. But when I try to create proxies through "Add Service References", I am getting the duplicate proxy classes. If I take out the above OperationContract and re run my services and try to create proxies, then "Add Service References" does not provide duplicate proxies. I am really confused about this!!!

  • TFS 2008 warning when trying to add set-up project

    - by pm_2
    I have a similar problem to that mentioned here. However, mine is in TFS 2008. I get the following warning when trying to add a set-up project to an existing solution (either just create the set-up project or “add to source control”). The project that you are attempting to add to source control may cause other source control users to have difficulty opening this solution or getting newer versions of it. To avoid this problem, add the project from a location below the binding root of the other source controlled projects in the solution Continue / Cancel As with the question above, I think my folder structure is at fault. However, the current folder structure is as follows: Solution Main Project My guess is that, for some reason it’s trying to add the set-up project directly into the solution folder. So, is there a way to validate where it’s trying to add this without selecting “Continue” above? Alternatively, is there a way to force the set-up project to create in its own folder?

  • many to many query for ActiveRecord

    - by JP
    I have three data models, Users, Conversations and Lines, where each conversation has many lines and certain participating users, each line has one conversation and one user and each user has many conversations and many lines. I have arranged these in ActiveRecord like this: class Line < ActiveRecord::Base belongs_to :conversation belongs_to :user end class User < ActiveRecord::Base has_and_belongs_to_many :conversations has_many :lines end class Conversation < ActiveRecord::Base has_many :lines has_and_belongs_to_many :users end If I want to create a new conversation with 4 users, where the users are either found or created inside the users table, how would I go about doing this? I thought I could do: c = Conversation.new c.users.find_or_create_by_username('myUsername') c.save But this will create a new username in the Users table even if that username already exists! (ie. running the above code 3 times will result in Users having 3 rows with 'myUsername' as the username, one for each conversation, rather than three conversations all with the same 'myUsername' entry listed in their associated users) I'm not sure how to search for this kind of information with google - can anyone help?

  • Java: Embedded Data Base

    - by Dmitry
    Hello! I want to create a desctop application with an embedded data base. Data base is JavaDB(Derby). I have connected a jar file derby.jar to my project. The problem is I don't understand how to register a driver to use this data base. It is said that I should use Class.forName("org.apache.derby.jdbc.EmbeddedDriver") But what if that was another data base and its driver was not in a java standart package? As you can see I'm confused with this. I want to know, how to use my connected derby.jar, how to work with its jdbc driver and how to create tables in a specified directory. Please, give as detailed answer, as you can. (I'm a dummy in this =)) )

  • How do I branch an individual file in SVN?

    - by Michael Carman
    The subversion concept of branching appears to be focused on creating an [un]stable fork of the entire repository on which to do development. Is there a mechanism for creating branches of individual files? For a use case, think of a common header (*.h) file that has multiple platform-specific source (*.c) implementations. This type of branch is a permanent one. All of these branches would see ongoing development with occasional cross-branch merging. This is in sharp contrast to unstable development/stable release branches which generally have a finite lifespan. I do not want to branch the entire repository (cheap or not) as it would create an unreasonable amount of maintenance to continuously merge between the trunk and all the branches. At present I'm using ClearCase, which has a different concept of branching that makes this easy. I've been asked to consider transitioning to SVN but this paradigm difference is important. I'm much more concerned about being able to easily create alternate versions for individual files than about things like cutting a stable release branch.

  • Django: Grouping by Dates and Servers

    - by TheLizardKing
    So I am trying to emulate google app's status page: http://www.google.com/appsstatus#hl=en but for backups for our own servers. Instead of service names on the left it'll be server names but the dates and hopefully the pagination will be there too. My models look incredibly similar to this: from django.db import models STATUS_CHOICES = ( ('UN', 'Unknown'), ('NI', 'No Issue'), ('IS', 'Issue'), ('NR', 'Not Running'), ) class Server(models.Model): name = models.CharField(max_length=32) def __unicode__(self): return self.name class Backup(models.Model): server = models.ForeignKey(Server) created = models.DateField(auto_now_add=True) modified = models.DateTimeField(auto_now=True) status = models.CharField(max_length=2, choices=STATUS_CHOICES, default='UN') issue = models.TextField(blank=True) def __unicode__(self): return u'%s: %s' % (self.server, self.get_status_display()) My issue is that I am having a hell of a time displaying the information I need. Everyday a little after midnight a cron job will run and add a row for each server for that day, defaulting on status unknown (UN). My backups.html: {% extends "base.html" %} {% block content %} <table> <tr> <th>Name</th> {% for server in servers %} <th>{{ created }}</th> </tr> <tr> <td>{{ server.name }}</td> {% for backup in server.backup_set.all %} <td>{{ backup.get_status_display }}</td> {% endfor %} </tr> {% endfor %} </table> {% endblock content %} This actually works but I do not know how to get the dates to show. Obviously {{ created }} doesn't do anything but the servers don't have create dates. Backups do and because it's a cron job there should only be X number of rows with any particular date (depending on how many servers we are following for that day). Summary I want to create a table, X being server names, Y being dates starting at today while all the cells being the status of a backup. The above model and template should hopefully give you an idea what my thought process but I am willing to alter anything. Basically I am create a fancy excel spreadsheet.

    Does anyone know how to delete Time Machine in Mac OS X 10.6.4? Before answering: sudo rm -rf /whateverthetimemachineis does not work Disabling the ACL permissions first with sudo fsaclctl -p /whatever -d does not work, sudo: fsaclctl: command not found Use the delete all backup feature in Time Machine... this is slow as hell, would take days. Need a command line solution. No I don't want to reformat the drive, I have other content on it, and no don't say I should have separated on two partition or two drives, I did it this say since partitions cannot be dynamically changed, and two drives is annoying since, whats the point of having a big drive?... plus has no relation to the issue at hand. Already googlied for hours and read everything on Super User, nothing working. and all solutions are the first 4. Any clues?

  • Returning values from Swing using invokeAndWait

    - by Joonas Pulakka
    I've been using the following approach to create components and return values from Swing to/from outside the EDT. For instance, the following method could be an extension to JFrame, to create a JPanel and add it to the parent JFrame: public JPanel threadSafeAddPanel() { final JPanel[] jPanel = new JPanel[1]; try { EventQueue.invokeAndWait(new Runnable() { public void run() { jPanel[0] = new JPanel(); add(jPanel[0]); } }); } catch (InterruptedException ex) { } catch (InvocationTargetException ex) { } return jPanel[0]; } The local 1-length array is used to transfer the "result" from inside the Runnable, which is invoked in the EDT. Well, it looks "a bit" hacky, and so my questions: Does this make sense? Is anybody else doing something like this? Is the 1-length array a good way of transferring the result? Is there an easier way to do this?

  • adding a flash object to FancyBox using jquery swfobject

  • The best way to separate admin functionality from a public site?

    - by AndrewO
    I'm working on a site that's grown both in terms of user-base and functionality to the point where it's becoming evident that some of the admin tasks should be separate from the public website. I was wondering what the best way to do this would be. For example, the site has a large social component to it, and a public sales interface. But at the same time, there's back office tasks, bulk upload processing, dashboards (with long running queries), and customer relations tools in the admin section that I would like to not be effected by spikes in public traffic (or effect the public-facing response time). The site is running on a fairly standard Rails/MySQL/Linux stack, but I think this is more of an architecture problem than an implementation one: mainly, how does one keep the data and business logic in sync between these different applications? Some strategies that I'm evaluating: 1) Create a slave database of the public facing database on another machine. Extract out all of the model and library code so that it can be shared between the applications. Create new controllers and views for the admin interfaces. I have limited experience with replication and am not even sure that it's supposed to be used this way (most of the time I've seen it, it's been for scaling out the read capabilities of the same application, rather than having multiple different ones). I'm also worried about the potential for latency issues if the slave is not on the same network. 2) Create new more task/department-specific applications and use a message oriented middleware to integrate them. I read Enterprise Integration Patterns awhile back and they seemed to advocate this for distributed systems. (Alternatively, in some cases the basic Rails-style RESTful API functionality might suffice.) But, I have nightmares about data synchronization issues and the massive re-architecting that this would entail. 3) Some mixture of the two. For example, the only public information necessary for some of the back office tasks is a read-only completion time or status. Would it make sense to have that on a completely separate system and send the data to public? Meanwhile, the user/group admin functionality would be run on a separate system sharing the database? The downside is, this seems to keep many of the concerns I have with the first two, especially the re-architecting. I'm sure the answers are going to be highly dependent on a site's specific needs, but I'd love to hear success (or failure) stories.

  • Updating D3 column chart with different values and different data sizes

    - by mbeasley
    Background I am attempting to create a reusable chart object with D3.js. I have setup a chart() function that will produce a column chart. On a click event on any of the columns, the chart will update with a new random data array that will contain a random number of data points (i.e. the original chart could have 8 columns, but upon update, could have 20 columns or 4 columns). Problem Say I have 8 data points (and thus 8 columns) in my original dataset. When I update the chart with random data, the columns appropriately adjust their height to the new values - but new bars aren't added. Additionally, while the width of the columns appropriately adjust to accommodate the width of the container and the new number of data points, if that number of data points is less than the original set, then some of those columns from the original dataset will linger until the number of data points is greater than or equal than the original. My end goal is to have new data dynamically added or old data outside of the range of the new data count dynamically removed. I've created a jsfiddle of the behavior. You may have to click the columns a couple of times to see the behavior I'm describing. Additionally, I've pasted my code below. Thanks in advance! function chart(config) { // set default options var defaultOptions = { selector: '#chartZone', class: 'chart', id: null, data: [1,2,6,4, 2, 6, 7, 2], type: 'column', width: 200, height: 200, callback: null, interpolate: 'monotone' }; // fill in unspecified settings in the config with the defaults var settings = $.extend(defaultOptions, config); function my() { // generate chart with this function var w = settings.width, h = settings.height, barPadding = 3, scale = 10, max = d3.max(settings.data); var svg = d3.select(settings.selector) // create the main svg container .append("svg") .attr("width",w) .attr("height",h); var y = d3.scale.linear().range([h, 0]), yAxis = d3.svg.axis().scale(y).ticks(5).orient("left"), x = d3.scale.linear().range([w, 0]); y.domain([0, max]).nice(); x.domain([0, settings.data.length - 1]).nice(); var rect = svg.selectAll("rect") .data(settings.data) .enter() .append("rect") .attr("x", function(d,i) { return i * (w / settings.data.length); }) .attr("y", function(d) { return h - h * (d / max); }) .attr("width", w / settings.data.length - barPadding) .attr("height", function(d) { return h * (d / max); }) .attr("fill", "rgb(90,90,90)"); svg.append("svg:g") .attr("class", "y axis") .attr("transform", "translate(-4,0)") .call(yAxis); svg.on("click", function() { var newData = [], maxCap = Math.round(Math.random() * 100); for (var i = 0; i < Math.round(Math.random()*100); i++) { var newNumber = Math.random() * maxCap; newData.push(Math.round(newNumber)); } newMax = d3.max(newData); y.domain([0, newMax]).nice(); var t = svg.transition().duration(750); t.select(".y.axis").call(yAxis); rect.data(newData) .transition().duration(750) .attr("height", function(d) { return h * (d / newMax); }) .attr("x", function(d,i) { return i * (w / newData.length); }) .attr("width", w / newData.length - barPadding) .attr("y", function(d) { return h - h * (d / newMax); }); }); } my(); return my; } var myChart = chart();

  • MVC Entity Framework Model not returning correct data

    - by quagland
    Hi, Run into a strange problem while writing an ASP.NET MVC site. I have a view in my SQL Server database that returns a few date ranges. The view works fine when running the query in SSMS. When the view data is returned by the Entity Framework Model, It returns the correct number of rows but some of the rows are duplicated. Here is an example of what I have done: SQL Server code: CREATE TABLE [dbo].[A]( [ID] [int] NOT NULL, [PhID] [int] NULL, [FromDate] [datetime] NULL, [ToDate] [datetime] NULL, CONSTRAINT [PK_A] PRIMARY KEY CLUSTERED ([ID] ASC)) ON [PRIMARY] go CREATE TABLE [dbo].[B]( [PhID] [int] NOT NULL, [FromDate] [datetime] NULL, [ToDate] [datetime] NULL, CONSTRAINT [PK_B] PRIMARY KEY CLUSTERED ( [PhID] ASC )) ON [PRIMARY] go CREATE VIEW C as SELECT A.ID, CASE WHEN A.PhID IS NULL THEN A.FromDate ELSE B.FromDate END AS FromDate, CASE WHEN A.PhID IS NULL THEN A.ToDate ELSE B.ToDate END AS ToDate FROM A LEFT OUTER JOIN B ON A.PhID = B.PhID go INSERT INTO B (PhID, FromDate, ToDate) VALUES (100, '20100615', '20100715') INSERT INTO A (ID, PhID, FromDate, ToDate) VALUES (1, NULL, '20100101', '20100201') INSERT INTO A (ID, PhID, FromDate, ToDate) VALUES (1, 100, '20100615', '20100715') INSERT INTO B (PhID, FromDate, ToDate) VALUES (101, '20101201', '20101231') INSERT INTO A (ID, PhID, FromDate, ToDate) VALUES (2, NULL, '20100801', '20100901') INSERT INTO A (ID, PhID, FromDate, ToDate) VALUES (2, 101, '20101201', '20101231') So now, if you select all from C, you get 4 separate date ranges In the Entity Framework Model (which I call 'Core'), the view 'C' is added. in MVC Controller: public class HomeController : Controller { public ActionResult Index() { CoreEntities db = new CoreEntities(); var clist = from c in db.C select c; return View(clist.ToList()); } } in MVC View: @model List<RM.Models.C> @{ foreach (RM.Models.C c in Model) { @String.Format("{0:dd-MMM-yyyy}", c.FromDate) <span>-</span> @String.Format("{0:dd-MMM-yyyy}", c.ToDate) <br /> } } When I run all this, it outputs this: 01-Jan-2010 - 01-Feb-2010 01-Jan-2010 - 01-Feb-2010 01-Aug-2010 - 01-Sep-2010 01-Aug-2010 - 01-Sep-2010 When it should do this (this is what the view returns): 01-Jan-2010 - 01-Feb-2010 15-Jun-2010 - 15-Jul-2010 01-Aug-2010 - 01-Sep-2010 01-Dec-2010 - 31-Dec-2010 Also, I've run the SQL profiler over it and according to that, the query being executed is: SELECT [Extent1].[ID] AS [ID], [Extent1].[FromDate] AS [FromDate], [Extent1].[ToDate] AS [ToDate] FROM (SELECT [C].[ID] AS [ID], [C].[FromDate] AS [FromDate], [C].[ToDate] AS [ToDate] FROM [dbo].[C] AS [C]) AS [Extent1] Which returns the correct data So it seems that the entity framework is doing something to the data in the meantime. To me, everything looks fine! Have I missed something? Cheers, Ben

  • Creating a standard card game (iPhone SDK)

    - by Chris
    I am trying to create a card game with a standard deck of cards. I need to be able to create a new card on screen every time someone draws a card from the deck and then be able to continuously move it throughout gameplay. I have image files for every card available in the game. I have tried creating a card object which held a UIImageView for the card along with some other basic data but I had trouble referring back to that card to move it again after the first touch. Was this the right way to do this?
