  • implementing match-making & community system for multiplayer games

    - by kamziro
    These days, games often have multiplayer portals with chat channels & match making system for the multiplayer aspects of the game. An example would be battle.net, magic the gathering online's chat rooms, halo etc. Now, for the rest of us indie gamers that probably won't be able to spend much development effort on creating those back-ends from scratch, what options do we have? I was thinking of something along the line of using IRC as the backbone of the system. From there, the "community" aspect and implement player tracking, game tracking and match making on top of that. It seems to be what the old battle.net (brood war era) used to be. The question is, is this easy to do? What does it take to run an irc server, and I suppose this also requires writing an IRC client (which seems to have been done a lot these days?)? If there are other ways as well (say, an open framework for this stuff), let's hear them too.

  • In a SSL web application, what would be the vulnerabilities of using session based authentication?

    - by Thomas C. G. de Vilhena
    I'm not sure the term even exists, so let me explain what I mean by "session based authentication" through some pseudo-code: void PerformLogin(string userName, string password) { if(AreValidCredentials(userName, password)) { Session.Set("IsAuthenticated", true); } else { Message.Show("Invalid credentials!"); } } So the above method simply verifies the provided credentials are valid and then sets a session flag to indicate that the session user is authenticated. Under plain HTTP that is obviously unsafe, because anyone could hijack the session cookie/querystring and breach security. However, under HTTPS the session cookie/querystring is protected because client-server communication is encrypted, so I believe this authentication approach would be safe, wouldn't it? I'm asking this because I want to know how authentication tickets can improve web applications security. Thanks in advance!

  • How much to charge Ruby on Rails Website [closed]

    - by eWizardII
    I figured it be appropriate to ask this question on webmasters, over the stackoverflow site seeing as there are similar questions here. I am freelancing for a client in the Boston area, who has the html/css templates for their site made by another web designer. They are basically looking for someone to set up the template, and then make the backend so that a user can purchase music on their site (they are musicians). I am wondering then what would be an appropriate amount to charge them to develop such a system, I am a student, and this would be my 3rd Ruby on Rails project, but probably at least the 20 web design project I have been hired to do and I have other programming knowledge, Python, C, etc. I am thinking of suggesting that they pay 1000usd to set up such a system, but I don't know if this is appropriate. To me it seems justifiable given my experience, and the low end of RoR developers I have seen charging 25usd/hr all the way up to 150usd/hr. Any advice would be appreciated.

  • Authentication for users on a Single Page App?

    - by John H
    I have developed a single page app prototype that is using Backbone on the front end and going to consume from a thin RESTful API on the server for it's data. Coming from heavy server side application development (php and python), I have really enjoyed the new different design approach with a thick client side MVC but am confused on how best to restrict the app to authenticated users who log in. I prefer to have the app itself behind a login and would also like to implement other types of logins eventually (openid, fb connect, etc) in addition to the site's native login. I am unclear how this is done and have been searching - but unsuccessful in finding information that made it clear to me. In the big picture, what is the current best practice for registering users and requiring them to login to use your single page app? Once a user is logged in, how are the api requests authenticated? Can I store a session but how do I detect for this session in the API calls? Any answers to this would be much appreciated!

  • Message Buffers in cloud

    - by kaleidoscope
    Message Buffer is WCF queue in the cloud (although currently it does not provide all features of WCF queue). With on-premise WCF, you can take advantage of MSMQ, so that a message is sent to MSMQ by one endpoint, and another endpoint can get the message in a later time. The message is usually a SOAP message so that you can generate a client proxy and invoke the service operations just as invoking a normal WCF operation. Message Buffer is similar, but it also provides a REST API for you to work with the messages. Use it when you need a reliable WCF service. Message buffers can be consumed by non-azure components, "Message  buffers are accessible to applications using HTTP and do not require the Windows Azure platform AppFabric SDK"              How to: Configure an AppFabric Service Bus Message Buffer :    please find below link for more details: http://msdn.microsoft.com/en-us/library/ee794877.aspx http://msdn.microsoft.com/en-us/library/ee794877.aspx   Chandraprakash, S

  • Software Architecture - From design to sucessful implementation

    - by user20358
    As the subject goes; once a software architect puts down the high level design and approach to a software that is to be developed from scratch, how does the team ensure that it is implemented successfully? To my mind the following things will need to be done Proper understanding of requirements Setting down coding practices and guidelines Regular code reviews to ensure the guidelines are being adhered to Revisiting the requirements phase and making necessary changes to design based on client inputs if there are any changes to requirements Proper documentation of what is being done in code Proper documentation of requirements and changes to them Last but not the least, implementing the design via object oriented code where appropriate Did I miss anything? Would love to hear any mistakes that you have learned from in your project experiences. What went wrong, what could have been done better. Thanks for taking the time..

  • Video monetising and simple shop, platform?

    - by fieldman
    I have this client that wants a single-product website. The product is a training-video that they want to deliver virtually and optionally physically. I usually do all the front-end design and back-end development but the budget is close to $0 to start with. So I'm looking for a platform like shopify or something where a shop/cart can be set up quickly and simply with minimal up-front cost - but which can accomodate some kind of paywall (DRM too?) for the online video with an option to purchase for an aditional cost the physical DVD. Am I approaching the wrong way all together? Or do you know of any platform that will accomodate the specs?

  • Is it good practice to analyse who introduced each bug?

    - by Michal Czardybon
    I used to analyse performance of programmers in my team by looking at the issues they have closed. Many of the issues are of course bugs. And here another important performance aspect comes - who introduced the bugs. I am wondering, if creating a custom field in the issue tracking system "Blamed" for reporting the person who generated the problem, is a good practice. One one hand it seems ok to me to promote personal responsibility for quality and this could reduce the additional work we have due to careless programming. On the other hand this is negative, things are sometimes vague and sometimes there is a reason such us "this thing had to be done very quickly due to a client's...". What to you think?

  • How to get working cups command line tools on Server 14.04

    - by Nick
    It looks like some of the commands like lpr and lprm have broken versions that don't work with cups. These commands worked properly on 10.04. lpr for cups has an -o option, but no lpr is intalled when cups is installed, and the lpr installed with apt-get install lpr does not have the -o option and does not appear to be the cups version of lpr. man lpr shows BSD General Commands Manual at the top, where man lpr on the Ubuntu 10.04 server said Apple, inc in the same spot. which leads me to believe the "wrong" lpr is in the "lpr" package or package names got moved around. There is also a lprng package, but trying to install it wants to remove cups and cups-client. lprm also returns lprm: PrinterName: unknown printer when PrinterName is in fact a valid printer installed with cups and does appear in lpstat -t. How do I get the proper cups versions of lpr working on Server 14.04?

  • Most efficient way to implement delta time

    - by Starkers
    Here's one way to implement delta time: /// init /// var duration = 5000, currentTime = Date.now(); // and create cube, scene, camera ect ////// function animate() { /// determine delta /// var now = Date.now(), deltat = now - currentTime, currentTime = now, scalar = deltat / duration, angle = (Math.PI * 2) * scalar; ////// /// animate /// cube.rotation.y += angle; ////// /// update /// requestAnimationFrame(render); ////// } Could someone confirm I know how it works? Here what I think is going on: Firstly, we set duration at 5000, which how long the loop will take to complete in an ideal world. With a computer that is slow/busy, let's say the animation loop takes twice as long as it should, so 10000: When this happens, the scalar is set to 2.0: scalar = deltat / duration scalar = 10000 / 5000 scalar = 2.0 We now times all animation by twice as much: angle = (Math.PI * 2) * scalar; angle = (Math.PI * 2) * 2.0; angle = (Math.PI * 4) // which is 2 rotations When we do this, the cube rotation will appear to 'jump', but this is good because the animation remains real-time. With a computer that is going too quickly, let's say the animation loop takes half as long as it should, so 2500: When this happens, the scalar is set to 0.5: scalar = deltat / duration scalar = 2500 / 5000 scalar = 0.5 We now times all animation by a half: angle = (Math.PI * 2) * scalar; angle = (Math.PI * 2) * 0.5; angle = (Math.PI * 1) // which is half a rotation When we do this, the cube won't jump at all, and the animation remains real time, and doesn't speed up. However, would I be right in thinking this doesn't alter how hard the computer is working? I mean it still goes through the loop as fast as it can, and it still has render the whole scene, just with different smaller angles! So this a bad way to implement delta time, right? Now let's pretend the computer is taking exactly as long as it should, so 5000: When this happens, the scalar is set to 1.0: angle = (Math.PI * 2) * scalar; angle = (Math.PI * 2) * 1; angle = (Math.PI * 2) // which is 1 rotation When we do this, everything is timsed by 1, so nothing is changed. We'd get the same result if we weren't using delta time at all! My questions are as follows Mostly importantly, have I got the right end of the stick here? How do we know to set the duration to 5000 ? Or can it be any number? I'm a bit vague about the "computer going too quickly". Is there a way loop less often rather than reduce the animation steps? Seems like a better idea. Using this method, do all of our animations need to be timesed by the scalar? Do we have to hunt down every last one and times it? Is this the best way to implement delta time? I think not, due to the fact the computer can go nuts and all we do is divide each animation step and because we need to hunt down every step and times it by the scalar. Not a very nice DSL, as it were. So what is the best way to implement delta time? Below is one way that I do not really get but may be a better way to implement delta time. Could someone explain please? // Globals INV_MAX_FPS = 1 / 60; frameDelta = 0; clock = new THREE.Clock(); // In the animation loop (the requestAnimationFrame callback)… frameDelta += clock.getDelta(); // API: "Get the seconds passed since the last call to this method." while (frameDelta >= INV_MAX_FPS) { update(INV_MAX_FPS); // calculate physics frameDelta -= INV_MAX_FPS; } How I think this works: Firstly we set INV_MAX_FPS to 0.01666666666 How we will use this number number does not jump out at me. We then intialize a frameDelta which stores how long the last loop took to run. Come the first loop frameDelta is not greater than INV_MAX_FPS so the loop is not run (0 = 0.01666666666). So nothing happens. Now I really don't know what would cause this to happen, but let's pretend that the loop we just went through took 2 seconds to complete: We set frameDelta to 2: frameDelta += clock.getDelta(); frameDelta += 2.00 Now we run an animation thanks to update(0.01666666666). Again what is relevance of 0.01666666666?? And then we take away 0.01666666666 from the frameDelta: frameDelta -= INV_MAX_FPS; frameDelta = frameDelta - INV_MAX_FPS; frameDelta = 2 - 0.01666666666 frameDelta = 1.98333333334 So let's go into the second loop. Let's say it took 2(? Why not 2? Or 12? I am a bit confused): frameDelta += clock.getDelta(); frameDelta = frameDelta + clock.getDelta(); frameDelta = 1.98333333334 + 2 frameDelta = 3.98333333334 This time we enter the while loop because 3.98333333334 = 0.01666666666 We run update We take away 0.01666666666 from frameDelta again: frameDelta -= INV_MAX_FPS; frameDelta = frameDelta - INV_MAX_FPS; frameDelta = 3.98333333334 - 0.01666666666 frameDelta = 3.96666666668 Now let's pretend the loop is super quick and runs in just 0.1 seconds and continues to do this. (Because the computer isn't busy any more). Basically, the update function will be run, and every loop we take away 0.01666666666 from the frameDelta untill the frameDelta is less than 0.01666666666. And then nothing happens until the computer runs slowly again? Could someone shed some light please? Does the update() update the scalar or something like that and we still have to times everything by the scalar like in the first example?

  • How to have a maintainable and manageable Javascript code base

    - by dade
    I am starting a new job soon as a frontend developer. The App I would be working on is 100% Javascript on the client side. all the server returns is an index page that loads all the Javascript files needed by the app. Now here is the problem: The whole of the application is built around having functions wrapped to different namespaces. And from what I see, a simple function like rendering the HTML of a page can be accomplished by having a call to 2 or more functions across different namespace... My initial thought was "this does not feel like the perfect solution" and I can just envisage a lot of issues with maintaining the code and extending it down the line. Now I would soon start working on taking the project forward and would like to have suggestions on good case practices when it comes to writing and managing a relatively large amount of javascript code.

  • migrating PR / rankings from one site to another

    - by sam
    Ive got a clients company site with decent PR, backlinks and search engines rankings. The client wants to change their comapany name and therfore URL, i will set up a rediect between the old site and the new site. But i was wandering is their a way to tell Google that they are moving while retaining all your rankings ? It is the same people, services, office building same everything just rebranded under a different name and url. Additionaly if their is a way to do this, how does google stop you buying expired domains and just pointing them onto your site, for instance i could buy several PR3 domains all relating to the same sector and point them at my site or would google catch on to this ?

  • Do logged in users need to browse a site over https?

    - by Luke
    I've never thought it was necessary, but a client has requested that all webpages served to logged in users be delivered over HTTPS. Aside from the implementation standpoint, which I don't think I'm going to pursue is there any real reason for this request ? For clarity, the login / logout process, account settings, registration preferences and all user related scripts are served over https. but I can't see the point in my news articles, press releases, events etc... being served in this manner? Am I missing something ?

  • Version hash to solve Event Sourcing problems

    - by SystematicFrank
    The basic examples I have seen about Event Sourcing do not deal with out of order events, clock offsets in different systems and late events from system partitions. I am wondering if more polished Event Sourcing implementations rely on a version stamp of modified objects? For example, assuming that the system is rendering the entity Client with version id ABCD1234. If the user modifies the entity, the system will create an event with the modified fields AND the version id reference to which version it applies. Later the event responder would detect out of order events and merge them.

  • Sample size and statistical significance in Google Analytics

    - by colmcq
    I have been asked to compile a report into dropout rates during checkout for a global webstore I have used a sample size over one month as my sample because: google analytics slows to a crawl over larger sample sizes and makes much of the analysis agonisingly small I believe it to be statistically significant and a representative sample My client has asked me why I didn't use yearly figures and wants proof that one month of data is 'statistically significant'. Am I right in thinking that I need to compare the standard deviation of my monthly sample to the yearly sample and ensure that the deviation is under a certain %age? Question: how do I prove one month of Google Analytics data is representative to one year worth of data? Stats: 90k unique views/month ~1.1m per year.

  • How to structure a set of RESTful URLs

    - by meetamit
    Kind of a REST lightweight here... Wondering which url scheme is more appropriate for a stock market data app (BTW, all queries will be GETs as the client doesn't modify data): Scheme 1 examples: /stocks/ABC/news /indexes/XYZ/news /stocks/ABC/time_series/daily /stocks/ABC/time_series/weekly /groups/ABC/time_series/daily /groups/ABC/time_series/weekly Scheme 2 examples: /news/stock/ABC /news/index/XYZ /time_series/stock/ABC/daily /time_series/stock/ABC/weekly /time_series/index/XYZ/daily /time_series/index/XYZ/weekly Scheme 3 examples: /news/stock/ABC /news/index/XYZ /time_series/daily/stock/ABC /time_series/weekly/stock/ABC /time_series/daily/index/XYZ /time_series/weekly/index/XYZ Scheme 4: Something else??? The point is that for any data being requested, the url needs to encapsulate whether an item is a Stock or an Index. And, with all the RESTful talk about resources I'm confused about whether my primary resource is the stock & index or the time_series & news. Sorry if this is a silly question :/ Thanks!

In both computers, I have allowed other users to control my computer in Desktop Sharing preferences, as below: When I try to connect to A from the B using Remmina Remote Desktop Client, it refuses to connect after trying for a while. These are my settings: I expect this to be done from an available open source software, not from TeamViewer. I found this guide harder to understand. Please provide me clear instructions... Thanks for having a look!

  • C++ : Lack of Standardization at the Binary Level

    - by Nawaz
    Why ISO/ANSI didn't standardize C++ at the binary level? There are many portability issues with C++, which is only because of lack of it's standardization at the binary level. Don Box writes, (quoting from his book Essential COM, chapter COM As A Better C++) C++ and Portability Once the decision is made to distribute a C++ class as a DLL, one is faced with one of the fundamental weaknesses of C++, that is, lack of standardization at the binary level. Although the ISO/ANSI C++ Draft Working Paper attempts to codify which programs will compile and what the semantic effects of running them will be, it makes no attempt to standardize the binary runtime model of C++. The first time this problem will become evident is when a client tries to link against the FastString DLL's import library from a C++ developement environment other than the one used to build the FastString DLL. Are there more benefits Or loss of this lack of binary standardization?

    - by Khaja Minhajuddin
    Ubuntu always surprises me by making things easier in unexpected ways. But, it isn't always obvious, For instance When I was looking for a tool to RDP into windows, I found that Ubuntu already has an pre-installed app called Terminal Server Client which has this functionality. I am sure there are many such hidden things which are not known to the average user. This thread could be used to expose these little gems. EDIT: Maybe the choice of my words was wrong, Are there any things which you found were not very obvious?
