  • Is there any kind of established architecture for browser based MMO games?

    - by black_puppydog
    I am beginning the development of a broser based game in which players take certain actions at any point in time. Big parts of gameplay will be happening in real life and just have to be entered into the system. I believe a good kind of comparison might be a platform for managing fantasy football, although I have virtually no experience playing that, so please correct me if I am mistaken here. The point is that some events happen in the program (i.e. on the server, out of reach for the players) like pulling new results from some datasource, starting of a new round by a game master and such. Other events happen in real life (two players closing a deal on the transfer of some team member or whatnot - again: have never played fantasy football) and have to be entered into the system. The first part is pretty easy since the game masters will be "staff" and thus can be trusted to a certain degree to not mess with the system. But the second part bothers me quite a lot, especially since the actions may involve multiple steps and interactions with different players, like registering a deal with the system that then has to be approved by the other party or denied and passed on to a game master to decide. I would of course like to separate the game logic as far as possible from the presentation and basic form validation but am unsure how to do this in a clean fashion. Of course I could (and will) put some effort into making my own architectural decisions and prototype different ideas. But I am bound to make some stupid mistakes at some point, so I would like to avoid some of that by getting a little "book smart" beforehand. So the question is: Is there any kind of architectural works that I can read up on? Papers, blogs, maybe design documents or even source code? Writing this down this seems more like a business application with business rules, workflows and such... Any good entry points for that?

  • An experiment: unlimited free trial

    - by Alex Davies
    The .NET Demon team have just implemented an experiment that is quite a break from Red Gate’s normal business model. Instead of the tool expiring after the trial period, it now continues to work, but with a new message that appears after the tool has saved you a certain amount of time. The rationale is that a user that stops using .NET Demon because the trial expired isn’t doing anyone any good. We’d much rather people continue using it forever, as long as everyone that finds it useful and can afford it still pays for it. Hopefully the message appearing is annoying enough to achieve that, but not for people to uninstall it. It’s true that many companies have tried it before with mixed results, but we have a secret weapon. The perfect nag message? The neat thing for .NET Demon is that we can easily measure exactly how much time .NET Demon has saved you, in terms of unnecessary project builds that Visual Studio would have done. When you press F5, the message shows you the time saved, and then makes you wait a shorter time before starting your application. Confronted with the truth about how amazing .NET Demon is, who can do anything but buy it? The real secret though, is that while you wait, .NET Demon gives you entertainment, in the form of a picture of a cute kitten. I’ve only had time to embed one kitten so far, but the eventual aim is for a random different kitten to appear each time. The psychological health benefits of a dose of kittens in the daily life of the developer are obvious. My only concern is that people will complain after paying for .NET Demon that the kittens are gone.

  • Drupal 7 on Windows - File Module Problems

    - by TimothyP
    Installed Drupal 7 using the Web Platform installer on Windows 2008 For some reason, the file module, when you upload a file, uses the first few letters of the filename as the unique key to store in the database, which of course causes problems very fast. I'm wondering does anybody have a workaround for this? An AJAX HTTP request terminated abnormally. Debugging information follows. Path: /file/ajax/field_file/und/0/form-EBMatHzV5cZXcWvXJtdADSdyw7Id9-GIpFM_NCJg_a4 StatusText: n/a ResponseText: Error message PDOException: SQLSTATE[23000]: [Microsoft][SQL Server Native Client 10.0][SQL Server]Cannot insert duplicate key row in object 'dbo.file_managed' with unique index 'uri_unique'. in drupal_write_record() (line 6776 of ..........\includes\common.inc).

  • Toolset agnostic build server and Silverlight projects

    - by Marko Apfel
    Problem Normally I try to have my continuous integration as most a possible toolset free to ensure that no local stuff could have an impact to my build. My Silverlight app references a special compile target in a folder outside my developer tree: <Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets" /> So I copied the stuff from this folder to a local one and changed the call to this target in my csproj: <Import Project="..\..\..\tools\WebApplications\Microsoft.WebApplication.targets" /> And now Visual Studio Conversion Wizard welcomes my with this: Solution Regardless of which line I write – this conversion comes back again and again, if the line has another form than <Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets" /> So it seems that there is no simple way to change this behaviour. Workaraound I must accept, that this line must be in the csproj and to run the build the toolset must be copied to the build server at the correct location. So go to your development machine where Visual Studio is installed and copy the folder “C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\WebApplications” to your build server at the equivalent location.   Xmas wishes to Microsoft: Please provide technologies to let us developers bundle all needed stuff for a project in one developer tree. It should be possible that one checkout starts us up! No additional installations regardless whether it is a developing machine or dedicated build or continuous integration server. Silverlight is only one example, code analysis configurations could also be terrible and much more …

  • Are all SATA cables compatible with SATA 3?

    - by Jim Fell
    I have a HP Compaq de5700 Small Form Factor desktop computer, and I am looking to upgrade it's hard drive. When I open up the box, it clearly has available SATA connectors on the motherboard, but no indication as to which SATA version (1, 2, or 3). The hard drive I am considering is a SATA 3. My concern is that if the motherboard also supports SATA 3 and I use an old SATA cable (v1 or v2), might there be problems? This is a bare drive, so I don't expect that a cable will come with it, and I have not been able to find the manual for this machine. Thanks.

  • How can we implement network search for Windows AND OS X clients?

    - by michielvoo
    We have a network with Windows 7 and OS X (10.5 and 10.6) computers. Our servers run on Windows Server 2003 (1 Small Business Server, 2 Standard). We need to be able to search through about 15.000 - 30.000 documents in our archives. The best solution would be if users can search directly from the Windows menu (on Windows 7) or the Spotlight menu (on OS X 10.5 and 10.6). Also good would be if users can search directly from the search bar in their browsers, or by first visiting a site with the search form. In case the users search through the browser, it's important they they are able to open a file in the search results just by clicking on it. I have tested Microsoft Search Server Express, but it doesn't meet the requirements (no OS X support, results in the browser can't be opened by clicking in anything but Internet Explorer). I have looked at Spotlight server, but that only supports OS X. Thanks!

  • Strange Windows Server 2008 R2 (FTP Server) Error - Caused by a specific combination of characters in the filename of uploaded file

    - by Steven
    We are running Windows Server 2008 R2, which is setup to be a FTP server. Everything seemed to be working fine until one our our cilents started complaining about their uploads being halted with the message "Connection with server reset". Further diagnosis revealed that a specific combination of characters in the filename will cause a repeatable error. I am hoping that a form expert can confirm the error or perhaps provide a solution. This is an example filename that will always cause the error: REPORT_FILED_000000001 (extension does not matter) Any help would be greatly appreciated! We need files named like this to work properly with our FTP server.

  • Focusing and Selecting the Text in ASP.NET TextBox Controls

    When a browser displays the HTML sent from a web server it parses the received markup into a Document Object Model, or DOM, which models the markup as a hierarchical structure. Each element in the markup - the <form> element, <div> elements, <p> elements, <input> elements, and so on - are represented as a node in the DOM and can be programmatically accessed from client-side script. What's more, the nodes that make up the DOM have functions that can be called to perform certain behaviors; what functions are available depend on what type of element the node represents. One function common to most all node types is focus, which gives keyboard focus to the corresponding element. The focus function is commonly used in data entry forms, search pages, and login screens to put the user's keyboard cursor in a particular textbox when the web page loads so that the user can start typing in his search query or username without having to first click the textbox with his mouse. Another useful function is select, which is available for <input> and <textarea> elements and selects the contents of the textbox. This article shows how to call an HTML element's focus and select functions. We'll look at calling these functions directly from client-side script as well as how to call these functions from server-side code. Read on to learn more! Read More >

  • Matlab: Why is '1' + 1 == 50? [migrated]

    - by phi
    Matlab has weak dynamic typing, which is what causes this weird behaviour. What I do not understand is what exactly happens, as this result really surprises me. Edit: To clarify, what I'm describing is clearly a result of Matlab storing chars in ASCII-format, which was also mentioned in the comments. I'm more interested in the way Matlab handles its variables, and specifically, how and when it assigns a type/tag to the values. Thanks. '1' is a 1-by-1 matrix of chars in matlab and '123' is a 1-by-3 matrix of chars. As expected, 1 returns a 1-by-1 double. Now if I enter '1' + 1 I get 50 as a 1-by-1 double, and if I enter '123' + 1 I get a 1-by-3 double [ 50 51 52 ] Furthermore, if I type 'a' + 1 the result is 98 in a 1-by-1 double. I assume this has to do with how Matlab stores char-variables in ascii form, but how exactly is it handling these? Are the data actually unityped and tagged, or how does it work? Thanks.

  • OpenXDK Questions

    - by iamcreasy
    I was strolling around XBox development. Apart form buying a DevKit from Microsoft, another thing got my attention is called, OpenXDK which stands for Open XBox Development Kit. From their main site its pretty obvious that there hasn't been any update since 2005 but digging a little deeper, I found that in their project repository is was being updated. Last time stamp was 2009-02-15. Quick google search said, its not actually really on a good place to poke around. Many and MANY features are absent. Being a hobby project I perfectly understand. But, those results are quite old. The question is, is there anybody who has any experience with OpenXDK? If is, that is it possible to shade some light on this? about its limitations? Is this a mature project? How's the latest version and what's it capable of doing? Or should I just stay away from it?

  • Remembering sharepoint password in Internet Explorer 8

    - by enableDeepak
    I am using IE8 to open a sharepoint portal on local network. Initially, I clicked on remember password after passing domain credentials. However, now I want sharepoint to ask credentials again. I've tried many options - Deleted all cookies, IE Security Tab Form Autocomplete Deleted everything. Restarted my machine. And all I could do. Still, when I open portal, sharepoint logs me in automatically. What should I do to make IE ask for credentials again?

  • Broadband Traffic Question

    - by rutherford
    I have a broadband ADSL line with plus.net in the UK. Having checked the modem there is no firewall or any weird features enabled. But since I arrived at the apartment (the broadband already being installed), I cannot log into Twitter nor update any of my wordpress blogs (I can browse them and log in, but cannot save any edits or new posts). It only seems to affect these two sites in their unique ways. If I take the netbook I use in this place out to say a McDonalds or some other wifi access point then these sites work fine again. Anyone know what could possibly be preventing access of the pages in question? The only thing common to these pages are the POST response they are expecting. But POST form submission works fine on other sites...

  • reverse_proxy (mod_rewrite) and rails

    - by SooDesuNe
    I have front end rails app, that reverse proxies to any of a number of backend rails apps depending on URL, for example http://www.my_host.com/app_one reverse proxies to http://www.remote_host_running_app_one.com such that a URL like http://www.my_host.com/app_one/users will display the contents of http://www.remote_host_running_app_one.com/users I have a large, and ever expanding number of backends, so they can not be explicitly listed anywhere other than a database. This is no problem for mod_rewrite using a prg:/ rewrite map reverse proxy. The question is, the urls returned by rails helpers have the form /controller/action making them absolute to the root. This is a problem for the page served by mod_rewrite because links on the proxied page appear as absolute to the domain. i.e.: http://www.my_host.com/app_one/controller/action has links that end up looking like /controller/action/ when they need to look like /app_one/controller/action Is there a way to fix this server-side, so that the links will be routed correctly?

  • Squid closing the connection on long HTTP GET requests

    - by Rhys
    When running a database query on a specific external site we use, Squid seems to cut off the connection after a consistent period of time (just over a minute). The query is submitted through a standard web form is that uses GET to query their database. Firefox 3 just displays a blank page. Internet Explorer throws a 'Page Cannot Be Displayed' error (tested in v6 and v8). When we perform the same query on the same machine, but bypass the Squid proxy, it works fine. The query takes about two and a half minutes to complete. There are a few timeout settings in Squid, but I honestly don't know what one to be looking at. Any possible solutions would be much appreciated. Cheers

  • JQuery Validation dates [migrated]

    - by james
    Im trying to get my form to validate...so basically its working, but a little bit too well, I have two text boxes, one is a start date, the other an end date in the format of mm/dd/yyyy if the start date is greater than the end date...there is an error if the end date is less than the start date...there is an error if the start date is less than today's date...there is an error The only thing is when I correct the error, the error warning is still there...here is my code: // Validate Date Ranges if ($(this).val() != '' && dates.not(this).val != '') { if ($(this).hasClass("FromCal")) { if (new Date(testDate) > new Date(otherDate)) { addError($(this)); $('.flightDateError').text('* Start date must be earlier than end date.'); isValid = false; return; } } else { if (new Date(testDate) < new Date(otherDate)) { addError($(this)); $('.flightDateError').text('* End date must be later than start date.'); return; } } } and here are the two text boxes: <div id="campaign_start" style="display: inline-block"> <label class="date_range_label">from:</label> <asp:TextBox ID="FromCalTbx" runat="server" Width="100px" CssClass="FromCal editable float_left required" /> </div> <div id="campaign_end" style="display: inline-block"> <label class="date_range_label">to:</label> <asp:TextBox ID="ToCalTbx" runat="server" Width="100px" CssClass="float_left optional"/> </div> PS - testDate is the start Date otherDate is the end Date

  • SonicWALL NetExtender - Client Install?

    - by JArmani
    We are about to push out a new VPN solution for our organization. One of the beautiful things we saw in SonicWALL's SSL-VPN was the thin, browser-based solution of NetExtender. Does anybody have experience with this? My specific concern is that, at least in Windows 7 during testing, it prompts for admin credentials to install the ActiveX NetExtender plugin, which is standard for installing anything in a Windows domain environment. But doesn't this mean I actually have to go in and install the client on all domain laptops that will be using the VPN in the field? They wouldn't actually be able to simply visit the site and run the client, as advertised? By the way, we're using the SonicWALL NSA 3500 device. We do have ManageEngine's Desktop Central, which can push out software installations, but it usually has to be in the form of a .MSI package. Is there any solution to this, besides hitting up all my organization's computers?

  • Software architecture map to aid cross team communication?

    - by locster
    I work in a company where multiple teams each work on different parts of a software product in a vaguely agile/scrum manner. Mostly the organisation works well but there have been instances where a team may make a change without realising its impact on other teams. Where dependence is known communication has been good, and where dependence is suspected then 'broadcast' emails and informal conversations have also worked well. But there exists a sub-set of tasks that fall between the cracks. Broadcast emails are likely not the solution as they would become too numerous such that the email signal/noise ratio would fall. I'm contemplating a solution that involves a sort of map of the software, which details all of the various parts of the system and loosely tries to place interacting and dependent parts near to each other. Each developer then updates their position on the map (today I'm working on X and Y), and therefore if two or more developers happen to be co-located (or proximate) on the map then we can see this each day and this could form the trigger for further discussion on possible overlap and conflict. Is such a method out there and in use? If so what is it and does it work? Otherwise, do you think such a scheme has merit?

  • Cutting up videos (excerpting) on Mac OS X -- iMovie produces super-large files

    - by markvgti
    I need to cut out parts of a video (+ the associated audio, of course) to make a short clip. For example, take 2 minutes from one location, 3 minutes from another part of the video, 30 seconds from another location and join it all together to form one single clip. The format of the input video is mp4 (H.264 encoding, AFAICR). Don't need very sophisticated merges or transitions from one part to the next, or sophisticated banners (text) on-screen, but some ability to do so would be a plus point. I've done this with iMovie in the past, but where the original file was under 5MB/min of play time, the chopped-up version was over 11MB/min of play time, which to me seems really bad. Is there a better/different way of doing this on OS X? Looking for free (gratis) solutions. OS: OS X 10.9.3

  • Template syntax for users - is there a right way to do it?

    - by RickM
    Ok, I'm in the middle of building a saas system, and as part of that, the hosted clients need to be able to edit certain layout templates, baqsically just html, css and javascript files. I'm obviously going to be wanting to use a template syntax here as it would be dumb to let people execute PHP code, so in this instance template syntax does need to be used. I know that in the grand scale of things, this is a very minor thing, but what template syntax do you use, and why? Is there one that's considered better than others? I've seen all sorts being used with no real consistency, for example: Smarty Style: {$someVar} {foreach from="foo" item="bar"} {$bar.food} {/foreach} ASP Style: {% someVar %} {% foreach foo as bar %} {% bar.food %} {% endforeach %} HTML Style: <someVar> <foreach from="foo" item="bar"> <bar:food> </foreach> PyroCMS/FuelPHP "LEX" Style: {{ someVar }} {{ foreach from="foo" item="bar" }} {{ bar:food }} {{ endforeach }} Obviously these arent 100% accurate (for example, LEX is used alongside PHP for loops), and are only to give you an example of what I mean. What, in your opinion would be the best one (if any) to go with. I ask this bearing in mind that people using this are likely to be novice users. I did look around at a bunch of hosted CMS and E-Commerce systems as these seem to make use of user-editable templates, and most seem to be using some form of their own syntax. I should note that whatever style I end up going with, it will be with a custom template handler due to the complexity of the system and how template files are stored. Plus I'd not want to touch the likes of Smarty with a barge pole!

  • sendmail new mail notification to external address only with the first unread email

    - by elcodedocle
    I'm running a webserver with a contact form which triggers a php script to sendmail the message to a local account on the server, and I want to be notified on my regular email account when I got new messages. I could have a notification per email or just send the emails directly to my account but that'd be too much: I just want a "you have new mail" notification sent to my email every time the inbox turns from 0 unread messages to 1. Google is burying me in sendmail documentation, and still can't find anything about it. Any ideas?

  • How to know if it's phishing or not in android apps?

    In IM apps (not only), there is a browser frame that appears and prompts for example to connect to facebook account, ebuddy for example (can't post pictures :( ) http://nsa34.casimages.com/img/2013/06/26//130626121230193046.jpg My question is: how can I know if this frame is from facebook.com and not a phishing website. I know that the apps in the play store are legit (mostly at least), but how can we trust apps that we install from outside the store? Or is there any way to check the credentials form action? Thanks for your answers and sorry for my bad english. (And sorry for the picture, couldn't make a screenshot ;-) )

  • Why doesnt file uploads work for a specific customer?

    - by nimo9367
    We have for some time now experienced some unexplainable behavior when a certain customer is trying to upload files to our web based application using a standard web form. It's a CGI based application and the server is running IIS6. However it works fine for all of our other customers using the same server and application so this must be a client side related issue? The request basically times out and you get to "page cannot be displayed". Does anyone have any idea of what might be the source of this problem?
