  • 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?

  • How do I write to an outer truecrypt volume when the inner volume protection prevents writng?

    - by con-f-use
    In a nutshell After some time using the outer volume of a hidden volume in Truecrypt I cannot write to the outer volume anymore. The protection of the inner volume always kicks in before. How do I fix this? Details I'm using truecrypt's two layered encryption of a USB stick. The outer container carries my semi-sensitive stuff while the inner hidden values has a bit more valuable information. I use both, the inner and outer volume regularly and that is part of the problem. Truecrypt can mount the outer volume for writing while protecting the inner. Usually the inner volume, when not protected this way (or mounted read-only) would be indistinguishable from free space. That is of course part of the plausible deniability scheme of truecrypt. At the beginning, everything worked as expected. I could copy and delete data to the outer volume as I pleased. Now it seams that I have written and deleted enough data to have filled the outer volume once. Despite the write protection Ubuntu tries now to write to the continuous "free space" that is the inner volume. It does that although enough other free space is on the outer volume. But on this free space there used to be data so its fragmented and the file system write prefers continuous space. The write on the continuous free space of the outer volume of course fails (with the error message in the picture above) as Truecrypt's inner-volume-protection kicks in. The Question I know this is expected behaviour, but is there a better way to write to the outer volume that does not attempt to write to the hidden free space at the end? The whole question could be more generally rephrased to: How do I control, where on a partition data is written in Ubuntu?

  • I've got my Master's in Software Engineering... Now what? [closed]

    - by Brian Driscoll
    Recently I completed a Master of Science in Software Engineering from Drexel University (Philadelphia, PA, US), because I wanted to have some formal education in software (my undergrad is in Math Ed) and also because I wanted to be able to advance my career beyond just programming. Don't get me wrong; I love to code. I spend a lot of my spare time coding. However, for me writing code is just a means to an end: what I REALLY love is designing software. Not visual design, mind you, but the architecture of the system. So, ideally I'd like to try to get a job doing software architecture. The problem is that I have no real experience in it besides my graduate course work. So, what should I do to make my "bones" in software architecture? UPDATE Just so it's clear, I have over 5 years of work experience in software development and an MCTS cert in addition to my education, so I'm not looking for the usual "I'm fresh out of school, what should I do?" advice.

  • I still can't figure out how to program!

    - by Mark K.
    Please help! I've read lots of programming books for various languages, Java, Python, C, etc. I understand and know all of the basics of the languages and I understand algorithms and data structures. (Equivilant of say 2 years of CompSci classes) BUT, I still can't figure how to write a program that does anything useful. All of the programming books show you how to write the language, but NOT how to use it! The programming examples are all very basic like build a card catalog for a library or a simple game or use algorithms etc... They dont't show you how to develop complex programs that actually do anything useful! I've looked a open-source programs on sourceforge, but they don't make much sense to me. There are hundreds of files in each program & thousands of lines of code. But how do I learn how to do this? There's nothing in any book I can buy on Amazon that will give me the tools to write any of these programs. How do you go from reading Intro to Java or Programming Python, or C Programming Language, etc.. to actually being able to say, I have an idea for X Program.. this is how I go about developing it? It seems like there is so much more involved in writing a program than you can learn in a book or from a class. I feel like there is someth Can anyone put me on the right track?

  • OpenGL depth texture wrong

    - by CoffeeandCode
    I have been writing a game engine for a while now and have decided to reconstruct my positions from depth... but how I read the depth seems to be wrong :/ What is wrong in my rendering? How I init my depth texture in the FBO gl::BindTexture(gl::TEXTURE_2D, this->textures[0]); // Depth gl::TexImage2D( gl::TEXTURE_2D, 0, gl::DEPTH32F_STENCIL8, width, height, 0, gl::DEPTH_STENCIL, gl::FLOAT_32_UNSIGNED_INT_24_8_REV, nullptr ); gl::TexParameterf(gl::TEXTURE_2D, gl::TEXTURE_MAG_FILTER, gl::NEAREST); gl::TexParameterf(gl::TEXTURE_2D, gl::TEXTURE_MIN_FILTER, gl::NEAREST); gl::TexParameterf(gl::TEXTURE_2D, gl::TEXTURE_WRAP_S, gl::CLAMP_TO_EDGE); gl::TexParameterf(gl::TEXTURE_2D, gl::TEXTURE_WRAP_T, gl::CLAMP_TO_EDGE); gl::FramebufferTexture2D( gl::FRAMEBUFFER, gl::DEPTH_STENCIL_ATTACHMENT, gl::TEXTURE_2D, this->textures[0], 0 ); Linear depth readings in my shader Vertex #version 150 layout(location = 0) in vec3 position; layout(location = 1) in vec2 uv; out vec2 uv_f; void main(){ uv_f = uv; gl_Position = vec4(position, 1.0); } Fragment (where the issue probably is) #version 150\n uniform sampler2D depth_texture; in vec2 uv_f; out vec4 Screen; void main(){ float n = 0.00001; float f = 100.0; float z = texture(depth_texture, uv_f).x; float linear_depth = (n * z)/(f - z * (f - n)); Screen = vec4(linear_depth); // It ISN'T because I don't separate alpha } When Rendered so gamedev.stackexchange, what's wrong with my rendering/glsl?

  • Making WatiN Wait for JQuery document.Ready() Functions to Complete

    - by Steve Wilkes
    WatiN's DomContainer.WaitForComplete() method pauses test execution until the DOM has finished loading, but if your page has functions registered with JQuery's ready() function, you'll probably want to wait for those to finish executing before testing it. Here's a WatiN extension method which pauses test execution until that happens. JQuery (as far as I can see) doesn't provide an event or other way of being notified of when it's finished running your ready() functions, so you have to get around it another way. Luckily, because ready() executes the functions it's given in the order they're registered, you can simply register another one to add a 'marker' div to the page, and tell WatiN to wait for that div to exist. Here's the code; I added the extension method to Browser rather than DomContainer (Browser derives from DomContainer) because it's the sort of thing you only execute once for each of the pages your test loads, so Browser seemed like a good place to put it. public static void WaitForJQueryDocumentReadyFunctionsToComplete(this Browser browser) { // Don't try this is JQuery isn't defined on the page: if (bool.Parse(browser.Eval("typeof $ == 'function'"))) { const string jqueryCompleteId = "jquery-document-ready-functions-complete"; // Register a ready() function which adds a marker div to the body: browser.Eval( @"$(document).ready(function() { " + "$('body').append('<div id=""" + jqueryCompleteId + @""" />'); " + "});"); // Wait for the marker div to exist or make the test fail: browser.Div(Find.ById(jqueryCompleteId)) .WaitUntilExistsOrFail(10, "JQuery document ready functions did not complete."); } } The code uses the Eval() method to send JavaScript to the browser to be executed; first to check that JQuery actually exists on the page, then to add the new ready() method. WaitUntilExistsOrFail() is another WatiN extension method I've written (I've ended up writing really quite a lot of them) which waits for the element on which it is invoked to exist, and uses Assert.Fail() to fail the test with the given message if it doesn't exist within the specified number of seconds. Here it is: public static void WaitUntilExistsOrFail(this Element element, int timeoutInSeconds, string failureMessage) { try { element.WaitUntilExists(timeoutInSeconds); } catch (WatinTimeoutException) { Assert.Fail(failureMessage); } }

  • JavaScript and callback nesting

    - by Jake King
    A lot of JavaScript libraries (notably jQuery) use chaining, which allows the reduction of this: var foo = $(".foo"); foo.stop(); foo.show(); foo.animate({ top: 0 }); to this: $(".foo").stop().show().animate({ top: 0 }); With proper formatting, I think this is quite a nice syntactic capability. However, I often see a pattern which I don't particularly like, but appears to be a necessary evil in non-blocking models. This is the ever-present nesting of callback functions: $(".foo").animate({ top: 0, }, { callback: function () { $.ajax({ url: 'ajax.php', }, { callback: function () { ... } }); } }); And it never ends. Even though I love the ease non-blocking models provide, I hate the odd nesting of function literals it forces upon the programmer. I'm interesting in writing a small JS library as an exercise, and I'd love to find a better way to do this, but I don't know how it could be done without feeling hacky. Are there any projects out there that have resolved this problem before? And if not, what are the alternatives to this ugly, meaningless code structure?

  • Loading images in XNA 4.0; "Cannot Open File" Problems

    - by user32623
    Okay, I'm writing a game in C#/XNA 4.0 and am utterly stumped at my current juncture: Sprite animation. I understand how it works and have all the code in place, but my ContentLoader won't open my file... Basically, my directory looks like this: //WindowsGame1 - "Game1.cs" - //Classes - "NPC.cs" - Content Reference - //Images - "Monster.png" Inside my NPC class, I have all the essential drawing functions, i.e. LoadContent, Draw, Update. And I can get the game to find the correct file and attempt to open it, but when it tries, it throws an exception and tells me it can't open the file. This is how my code in my NPC class looks: Texture2D NPCImage; Vector2 NPCPosition; Animation NPCAnimation = new Animation(); public void Initialize() { NPCAnimation.Initialize(NPCPosition, new Vector2(4, 4)); } public void LoadContent(ContentManager Content) { NPCImage = Content.Load<Texture2D>("_InsertImageFilePathHere_"); NPCAnimation.AnimationImage = NPCImage; } The rest of the code is irrelevant at this point because I can't even get the image to load. I think it might have to do with a directory problem, but I also know little to nothing about spriting or working with images or animations in my code. Any help is appreciated. Not sure if I provided enough information here, so let me know if more is needed! Also, what would be the correct way to direct that Content.Load to Monster.png given the current directory situation? Right now I just have it using the full path from the C:// drive. Thanks in advance!

  • Ubuntu 12.10 wont boot

    - by John Mark High
    im new to using Ubuntu and just bought a HP Pavilion g6-2240sa with windows 8 pre installed. I made a bootable USB with Ubuntu on it and installed alsongside windows, for 2 days it worked fine, I got into Ubuntu by doing an advanced restart from windows 8 and then booting Ubuntu from the partition it made. When i did the advanced restart today there was only 1 HDD i could select ( there were 3 before windows, a restore partition that was already there when i got the computer and Ubuntu) so i booted from the USB again and re-installed Ubuntu. then did an advanced restart and the 3 partitions where there again, i booted from Ubuntu and now heres my problem. I get the Ubuntu background when its loading then its just a black screen with some writing, its not on long enough to read, then just a black screen with a white _ and the top left corner that does nothing, i have to restat the computer and it auto boots into windows 8. im a little confused as the first time i installed Ubuntu it worked fine until the partition dissaperd), the second time i installed i did everything the same except it found the old Ubuntu so i reinstalled it and now is donst work.

  • Should a software developer get a yearly equipment budget?

    - by CrazyDart
    I am looking at a new position with a new company. I have talked to some people in the past (in general, not at this company) that they had been given a yearly budget to buy new computer stuff to keep up to date. Now why I feel this question is worth asking here is that Joel comes right out and says an employer should pay for the best equipment money can buy... within reason of course. From The Joel Test: 12 Steps to Better Code 9. Do you use the best tools money can buy? Writing code in a compiled language is one of the last things that still can't be done instantly on a garden variety home computer... Top notch development teams don't torture their programmers. Even minor frustrations caused by using underpowered tools add up, making programmers grumpy and unhappy. And a grumpy programmer is an unproductive programmer... Does anyone know if the industry has such a standard to offer an allowance or budget? I have never worked for a company like this, but I am thinking I should toss this in the ring for negotiations. Seems reasonable. How do bigger companies like MS, Google, and Apple handle this? If you say yes, give a range... I have been told numbers from $5k to $10k. Seems high to me, but hey I would gladly take it.

  • What will be the better way for data retrieval on application that needs to handle limited amount of data?

    - by Milanix
    Just moved this question from Stack Overflow. Since, adding my code snippets itself would make this question really long. Instead, I am pretty interested in knowing a better ways for data retrieval on application that needs to handle limited amount of data which isn't updated regularly. Let's take this example: I am writing an application which gets a schedule as an XML from server. I have written a logic in order to parse XML version and update database only if the version is newer than the local version. Although the update is checked automatically/manually on daily basis based on user preference, the actual version update happens only once per few months or so. Since, this is done by some other authority which doesn't provide API but, rather inform publicly on their changes. The actual XML contains a "(n number of groups)(days in a week) (n number of schedule)" . The group is usually 6 and the number of schedule is usually 2. So basically there would usually be only around 100 strings. Now although I have used SQLite at the moment. I want to know how to make update on database. Should I show progress dialog that the application is updating and exit the app when it's done? Since, my updates are infrequent i don't think this will really harm user experience but, is there any better ways to do it? Because I don't want update to be made when user is searching which is done using database. This will cause an database already open exception. At least I have faced this problem before. Is it better to rather parse XML every time when user wants to view certain things or to use SQLite? Since, I make lots of use of adapter in my app to create lists, will that degrade the performance?

  • Storage of leftover values in a situation of having to round down

    - by jt0dd
    I'm writing an app (client and server side) where the number of sales required by each employee must be kept track of in round-number form. Each month, the employees are required to sell a certain number, and this app needs to keep track of how many sales must be made for each 12 hour interval during the work week. Because I have to round the values down to a whole number, I must keep track of leftovers in the rounding process and ensure that they are always carried over. My method must ensure the storage of the leftover value even when client and server side crash, restart, close, etc. Right now, I'm working on doing this by storing the leftovers in a field in the user's account row in the database each time a value is rounded, reading the stored value, removing any portion that is used (when a whole number is reached, most of the leftover is used up), and storing the new value. This practice seems weird because while the leftovers are calculated on the client side, it's the same number for each employee, and every employee using the app is storing a copy of the same leftover data. Alternatively, I could have all clients store the data at once into the same data field on a general table, but this is just as weird. Is there a better way that this can be handled or is my method correct?

  • Are small amounts of functional programming understandable by non-FP people?

    - by kd35a
    Case: I'm working at a company, writing an application in Python that is handling a lot of data in arrays. I'm the only developer of this program at the moment, but it will probably be used/modified/extended in the future (1-3 years) by some other programmer, at this moment unknown to me. I will probably not be there directly to help then, but maybe give some support via email if I have time for it. So, as a developer who has learned functional programming (Haskell), I tend to solve, for example, filtering like this: filtered = filter(lambda item: included(item.time, dur), measures) The rest of the code is OO, it's just some small cases where I want to solve it like this, because it is much simpler and more beautiful according to me. Question: Is it OK today to write code like this? How does a developer that hasn't written/learned FP react to code like this? Is it readable? Modifiable? Should I write documentation like explaining to a child what the line does? # Filter out the items from measures for which included(item.time, dur) != True I have asked my boss, and he just says "FP is black magic, but if it works and is the most efficient solution, then it's OK to use it." What is your opinion on this? As a non-FP programmer, how do you react to the code? Is the code "googable" so you can understand what it does? I would love feedback on this :) Edit: I marked phant0m's post as answer, because he gives good advice on how to write the code in a more readable way, and still keep the advantages. But I would also like to recommend superM's post because of his viewpoint as a non-FP programmer.

  • Java and C# in web development [on hold]

    - by azalut
    I am wondering whether C# development(ASP.NET) is rather kind of "rapid development" or something "big" like JavaEE/Spring? We all know, that RoR or Django are really rapid-development frameworks - and so - is C# closer to Java "long-timed-development" or to frameworks like the two above - Django, RoR? I am, for now, an amateur Java programmer and sometimes I get annoyed with the amount of code that have to be written to create even a short CRUD app. We need a lot of skills to create at least a small app. I want some change, at least for some time and learn something new. I tried (just few hours) first: RoR, then Django and now I am writing in C#. It seems to be like Java but a little bit extended. In respect of future work as a professional coder - Is it profitable to know both competitive technologies like Java (and its frameworks) and C# with .NET(ASP.NET for example)? Maybe better choice is Python? Or just stop being stupid and still work with Java but with another framework(and master my Java skills) or JavaScript, jQuery to be better at web-development? Actually this question depends on your own opinions that is why I know that this question could be blocked by admins. But main question is in the top of the post I mean: is C# web-development rapid or closer to Java? I am afraid, that if I don't try, I will regret in the future, when I awake and think: oh my god, how could I not get familiar with (another_technology_or_language) Thanks for your attention :) ps I had asked the same question on stackoverflow, but it was hold because of being opinion based. Hope it fits here ;)

  • Take a snapshot with JavaFX!

    - by user12610255
    JavaFX 2.2 has a "snapshot" feature that enables you to take a picture of any node or scene. Take a look at the API Documentation and you will find new snapshot methods in the javafx.scene.Scene class. The most basic version has the following signature: public WritableImage snapshot(WritableImage image) The WritableImage class (also introduced in JavaFX 2.2) lives in the javafx.scene.image package, and represents a custom graphical image that is constructed from pixels supplied by the application. In fact, there are 5 new classes in javafx.scene.image: PixelFormat: Defines the layout of data for a pixel of a given format. WritablePixelFormat: Represents a pixel format that can store full colors and so can be used as a destination format to write pixel data from an arbitrary image. PixelReader: Defines methods for retrieving the pixel data from an Image or other surface containing pixels. PixelWriter: Defines methods for writing the pixel data of a WritableImage or other surface containing writable pixels. WritableImage: Represents a custom graphical image that is constructed from pixels supplied by the application, and possibly from PixelReader objects from any number of sources, including images read from a file or URL. The API documentation contains lots of information, so go investigate and have fun with these useful new classes! -- Scott Hommel

  • Using onboard and pci-e graphics card at the same time

    - by Endle
    Hello wonderful people. I know there are several other posts with similar questions. I also know how to use Google. I also have read up on posts discussing bumblebee, crossfire, ati catylist and many other interesting topics. I would just like someone to give me advice on how to use the onboard and pci-e graphics at the same time. I know the computer is capable of doing this. It works in Windows. I can use the VGA and DVI onboard port and the HDMI port of the add on card all at the same time. Works great in Windows 7, In Ubuntu, it seems only one or the other will work. I can use any combination of two displays on either adapter: VGA and HDMI..HDMI and DVI..so forth and so on. I have started experimenting with xorg.conf files, but have not been able to get any of them to work. Here is my last attempt at writing an xorg.conf file: Section "ServerLayout" Identifier "X.org Configured" Screen 0 "Screen0" 0 0 Screen 1 "Screen1" LeftOf "Screen0" Screen 2 "Screen2" LeftOf "Screen1" InputDevice "Mouse0" "CorePointer" InputDevice "Keyboard0" "CoreKeyboard" EndSection Section "Device" Identifier "Onboard Video" Driver "radeon" BusID "PCI:01:05.0" EndSection Section "Device" Identifier "Graphics Card" Driver "radeon" BusID "PCI:02:00.0" EndSection Section "Monitor" Identifier "CRT2" Option "VendorName" "ViewSonic" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" EndSection Section "Monitor" Identifier "DVI1" VendorName "ACR" ModelName "P224W" Option "DPMS" EndSection Section "Monitor" Identifier "DVI2" Option "VendorName" "Acer" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" EndSection Section "Screen" Identifier "Screen0" Device "Onboard Video" Monitor "CRT2" DefaultDepth 24 SubSection "Display" Depth 24 Modes "1280x1024" EndSubSection EndSection Section "Screen" Identifier "Screen1" Device "Graphics Card" Monitor "DVI1" DefaultDepth 24 SubSection "Display" Depth 24 Modes "1920x1080" EndSubSection

  • Sub-systems in game engines

    - by Hillel
    So here's the problem- I'm writing my own engine library, and it works fine with stuff like menus and the actual game screen. The thing is, I can't really figure out how to integrate something like an intro or dialogue preceding certain levels into this system. Let's look at another example- say I have a game-specific engine which gets a Level object and runs it. Engine would have its own collision and physics system, all hard coded. Now, what if at some point in a level, I want the player to enter a mini-game with different rules? How do I morph the Engine class to support these sub-systems without having to deal with their code all the time (as in: if(regular game) ... else if(mini game) ...)? And what if I want an intro animation at the start of a level, and I want the player to be able to assume control of his character once the animation ends, do I implement the animation into the Engine class itself? Or maybe I need to run another class, CutScene, and when it ends, it calls Engine and starts the level? What if I want to add a dialogue system, where at the start of each level there's a short dialogue and the player can't control his character, and once it ends, he can? Would I then run the dialogue code inside the Engine code? Maybe these sub-systems should all be scripted? I don't know anything about scripting, is it necessary for this kind of situation? Any help would be appreciated.

  • Integrating Amazon EC2 in Java via NetBeans IDE

    - by Geertjan
    Next, having looked at Amazon Associates services and Amazon S3, let's take a look at Amazon EC2, the elastic compute cloud which provides remote computing services. I started by launching an instance of Ubuntu Server 14.04 on Amazon EC2, which looks a bit like this in the on-line AWS Management Console, though I whitened out most of the details: Now that I have at least one running instance available on Amazon EC2, it makes sense to use the services that are integrated into NetBeans IDE:  I created a new application with one class, named "AmazonEC2Demo". Then I dragged the "describeInstances" service that you see above, with the mouse, into the class. Then the IDE automatically created all the other files you see below, i.e., 4 Java classes and one properties file: In the properties file, register the access ID and secret keys. These are read by the other generated Java classes. Signing and authentication are done automatically by the code that is generated, i.e., there's nothing generic you need to do and you can immediately begin working on your domain-specific code. Finally, you're now able to rewrite the code in "AmazonEC2Demo" to connect to Amazon EC2 and obtain information about your running instance: public class AmazonEC2Demo { public static void main(String[] args) { String instanceId1 = "i-something"; RestResponse result; try { result = AmazonEC2Service.describeInstances(instanceId1); System.out.println(result.getDataAsString()); } catch (IOException ex) { Logger.getLogger(AmazonEC2Demo.class.getName()).log(Level.SEVERE, null, ex); } } } From the above, you'll receive a chunk of XML with data about the running instance, it's name, status, dates, etc. In other words, you're now ready to integrate Amazon EC2 features directly into the applications you're writing, without very much work to get started. Within about 5 minutes, you're working on your business logic, rather than on the generic code that anyone needs when integrating with Amazon EC2.

  • How can I reduce the amount of time it takes to fully regression test an application ready for release?

    - by DrLazer
    An app I work on is being developed with a modified version of scrum. If you are not familiar with scrum, it's just an alternative approach to a more traditional watefall model, where a series of features are worked on for a set amount of time known as a sprint. The app is written in C# and makes use of WPF. We use Visual C# 2010 Express edition as an IDE. If we work on a sprint and add in a few new features, but do not plan to release until a further sprint is complete, then regression testing is not an issue as such. We just test the new features and give the app a good once over. However, if a release is planned that our customers can download - a full regression test is factored in. In the past this wasn't a big deal, it took 3 or 4 days and the devs simply fix up any bugs found in the regression phase, but now, as the app is getting larger and larger and incorporating more and more features, the regression is spanning out for weeks. I am interested in any methods that people know of or use that can decrease this time. At the moment the only ideas I have are to either start writing Unit Tests, which I have never fully tried out in a commercial environment, or to research the possibilty of any UI Automation API's or tools that would allow me to write a program to perform a series of batch tests. I know literally nothing about the possibilities of UI automation so any information would be valuable. I don't know that much about Unit testing either, how complicated can the tests be? Is it possible to get Unit tests to use the UI? Are there any other methods I should consider? Thanks for reading, and for any advice in advance.

  • Finite Numbers and ExplorerCanvas

    - by PhubarBaz
    I was working on my online mathematical graphing application, CloudGraph, and trying to make it work in IE. The app uses the HTML5 canvas element to draw graphs. Since IE doesn't support canvas yet I use ExplorerCanvas to provide that support for IE. However, it seems that when using excanvas, if you try to moveTo or drawTo a point that is not finite it loses it's mind and stops drawing anything else after that. I had no such problems in Firefox or Chrome so it took me awhile to figure out what was going on. Next I discovered that I needed a way to check if a variable was NaN or Inifinity or any other non-finite value so I could avoid calling moveTo() in that case. I started writing a long if statement, then I thought there has to be a better way. Sure enough there was. There just happens to be an isFinite() function built into Javascript just for this purpose. Who knew! It works great. Another difference I discovered with excanvas is that you must specify a starting point using a moveTo() when beginning a drawing path. Again, Chrome and Firefox are a lot more forgiving in this area so it took me a while to figure out why my lines weren't drawing. But, all is happy now and I'm a little wiser to the ways of the canvas.

  • Run script at user login as root, with a catch

    - by tubaguy50035
    I'm trying to run a PHP script as root on user login. The PHP script adds a Samba share to the Samba config, thus the need for root privileges. The only issue here, is that the user doesn't exist yet. This system is integrated with active directory. So when a user logs in for the first time, a home directory for them is created under /home/DOMAIN/username. I've found this question and that seems like the correct way to get what I want, but I'm having trouble with the syntax since I don't know the user's name. Would it be something like: ALL ALL=(ALL) NOPASSWD: /home/DOMAIN/*/createSambaShare.php This doesn't seem to work as it is currently. Anyone have any ideas or a "scripted" way to add a Samba share on user login? Since I've made other changes to /etc/skel, I just added the bash necessary to run the PHP script in .profile in there. This then gets copied to the "new" user's home and it tries to run the PHP script. But it fails, because these are not privileged users. Changing permissions on the PHP script will not help. It needs to be run as sudo because it opens the Samba config file for writing. Letting any user run the PHP script would result in a PHP error. The homes Samba directive doesn't work for my use case. I need the Samba share to exist once they exist on the server, even when they're not logged in.

  • Interface (contract), Generics (universality), and extension methods (ease of use). Is it a right design?

    - by Saeed Neamati
    I'm trying to design a simple conversion framework based on these requirements: All developers should follow a predefined set of rules to convert from the source entity to the target entity Some overall policies should be able to be applied in a central place, without interference with developers' code Both the creation of converters and usage of converter classes should be easy To solve these problems in C# language, A thought came to my mind. I'm writing it here, though it doesn't compile at all. But let's assume that C# compiles this code: I'll create a generic interface called IConverter public interface IConverter<TSource, TTarget> where TSource : class, new() where TTarget : class, new() { TTarget Convert(TSource source); List<TTarget> Convert(List<TSource> sourceItems); } Developers would implement this interface to create converters. For example: public class PhoneToCommunicationChannelConverter : IConverter<Phone, CommunicationChannle> { public CommunicationChannel Convert(Phone phone) { // conversion logic } public List<CommunicationChannel> Convert(List<Phone> phones) { // conversion logic } } And to make the usage of this conversion class easier, imagine that we add static and this keywords to methods to turn them into Extension Methods, and use them this way: List<Phone> phones = GetPhones(); List<CommunicationChannel> channels = phones.Convert(); However, this doesn't even compile. With those requirements, I can think of some other designs, but they each lack an aspect. Either the implementation would become more difficult or chaotic and out of control, or the usage would become truly hard. Is this design right at all? What alternatives I might have to achieve those requirements?

  • ASP.NET MVC Cookbook - public review

    - by asiemer
    I have recently started writing another book.  The topic of this book is ASP.NET MVC.  This book differs from my previous book in that rather than working towards building one project from end to end - this book will demonstrate specific topics from end to end.  It is a recipe book (hence the cookbook name) and will be part of the Packt Publishing cookbook series.  An example recipe in this book might be how to consume JSON, creating a master /details page, jquery modal popups, custom ActionResults, etc.  Basically anything recipe oriented around the topic of ASP.NET MVC might be acceptable.  If you are interested in helping out with the review process you can join the "ASP.NET MVC 2 Cookbook-review" group on Google here: http://groups.google.com/group/aspnet-mvc-2-cookbook-review Currently the suggested TOC for the project is listed.  Also, chapters 1, 2, and most of 8 are posted.  Chapter 5 should be available tonight or tomorrow. In addition to reporting any errors that you might find (much appreciated), I am very interested in hearing about recipes that you want included, expanded, or removed (as being redundant or overly simple).  Any input is appreciated!  Hearing user feedback after the book is complete is a little late in my opinion (unless it is positive feedback of course). Thank you!

  • i18n and L10n (1)

    - by Aaron Li
    Internationalization (i18n) is a way of designing and developing a software product to function in multiple locales. This process involves identifying the locales that must be supported, designing features which support those locales, and writing code that functions equally well in any of the supported locales. Localization (L10n) is a process of modifying or adapting a software product to fit the requirements of a particular locale. This process includes (but may not be limited to) translating the user interface, documentation and packaging, changing dialog box geometries, customizing features (if necessary), and testing the translated product to ensure that it still works (at least as well as the original). i18n is a pre-requisite for L10n. Resource is 1. any part of a program which can appear to the user or be changed or configured by the user. 2. any piece of the program's data, as opposed to its code. Core product is the language independent portion of a software product (as distinct from any particular localized version of that product - including the English language version). Sometimes, however, this term is used to refer to the English product as opposed to other localizations.   Useful links http://www.mozilla.org/docs/refList/i18n/ http://www.w3.org/International/ http://hub.opensolaris.org/bin/view/Community+Group+int_localization/
