• Design pattern for client/server sessions?

  - by nonot1

  Are there any common patterns or general guidance I can learn from for how to design a client/server system where the both the client and server must maintain some kind per-client session state? I've found any number of libraries that can help with some of the plumbing, but it's the overall design I'm wondering about. Open issues in my mind: How to structure the client/server communication so that bidirectional synchronous and asynchronous requests are possible? The server side needs to spawn a couple of per-connected-client session-long helper process. How to manage that? How to manage the mapping from a given client (and any of it's requests) to server state and helper process instances in the face of multiple clients and intermittent network connectivity. Most communication can be simple blocking request/reply, but some will be long running processing tasks that the client will want to keep tabs on. To the extent that it matters, the platform is Linux/C/C++. Not web based. Just an existing thick-client software app being modified to talk to backend servers for some tasks.

• Logarithmic spacing of FFT bins

  - by Mykel Stone

  I'm trying to do the examples within the GameDev.net Beat Detection article ( http://archive.gamedev.net/archive/reference/programming/features/beatdetection/index.html ) I have no issue with performing a FFT and getting the frequency data and doing most of the article. I'm running into trouble though in the section 2.B, Enhancements and beat decision factors. in this section the author gives 3 equations numbered R10-R12 to be used to determine how many bins go into each subband: R10 - Linear increase of the width of the subband with its index R11 - We can choose for example the width of the first subband R12 - The sum of all the widths must not exceed 1024 He says the following in the article: "Once you have equations (R11) and (R12) it is fairly easy to extract 'a' and 'b', and thus to find the law of the 'wi'. This calculus of 'a' and 'b' must be made manually and 'a' and 'b' defined as constants in the source; indeed they do not vary during the song." However, I cannot seem to understand how these values are calculated...I'm probably missing something simple, but learning fourier analysis in a couple of weeks has left me Decimated-in-Mind and I cannot seem to see it.

• The next next C++ [closed]

  - by Roger Pate

  It's entirely too early for speculation on what C++ will be like after C++0x, but idle hands make for wild predictions. What features would you find useful and why? Is there anything in another language that would fit nicely into the state of C++ after 0x? What should be considered for the next TC and TR? (Mostly TR, as the TC would depend more on what actually becomes the next standard.) Export was removed, rather than merely deprecated, in 0x. (It remains a keyword.) What other features carry so much baggage to also be more harmful than helpful? ISO Standards' process I'm not involved in the C++ committee, but it's also a mystery, unfortunately, to most programmers using C++. A few things worth keeping in mind: There will be 10 years between standards, barring extremely exceptional circumstances. The standard can get "bug fixes" in the form of a Technical Corrigendum. This happened to C++98 with TC1, named C++03. It fixed "simple" issues such as making the explicit guarantee that std::vector stores items contiguously, which was always intended. The committee can issue reports which can add to the language. This happened to C++98/03 with TR1 in 2005, which introduced the std::tr1 namespace.

• Which toolkit to use for 3D MMO game development?

  - by Ahmet Yildirim

  Lately i've been thinking about which path to follow for developing an 3D Online game. I have googled a lot but i couldnt find a good article that covers both game development and online server & client development in same context. This question has been in mind for about 2 weeks now. So.. yesterday i started developing a game from scratch by using Irrlicht.Net Wrapper to use Socket library of .NET which im already familiar. But i found out .Net wrapper of Irrlicht is not totally finished yet and still have lacks from the original. So i lost all my motives :/. So i thought why not to ask the experts before i run into another dead end... What Game Engine and Networking Library is best way to go for 3D MMO Development? Here is some of my early conclusions: Please let me know the ones im wrong. C++: Best Performance for 3D Graphics. Most Game Engines has native C++ Libraries. Lacks a Solid Socket Library .NETC++ Lacks Intellisense Support. C#: Intellisense Support NET Socket Library Lacks 3D Graphics Performance Lacks a native solid 3D Game Engine

• I need advice on how to best handle an e-commerce situation

  - by Mohamad

  I recently moved to Brazil and started a small subscription based service company. The payment gateway market is under-developed in Brazil, and implementing a local solution is too expensive for me. My requirements are a payment gateway that will automatically process monthly recurrent billing, and that will allow me to manually charge my customers when needed. They would also have to deal with storage and security. I'm leaning towards manually processing payments myself as a restaurant would do, for example, using small swipe machines. Unfortunately, this would require me to store credit card information and I would rather not, but I feel it's my only option. Can anyone give me advice on how to tackle this problem? Do I have other options? If I decide to store credit card information, what should I keep in mind and how should I go about it? I have moderate skills in programming, and through tenacity I can get most things done. I'm afraid that this might be out of my league, however.

• Xubuntu 14.04 with Compton, strange screen tearing, only when playing videos though (advice needed)

  - by LinuxDudester

  Hello beloved community, Yet again I am in need of your great expertise. I ran into a very strange issue and just can't wrap my mind around it. I'm running Xubuntu 14.04 exclusively, with Compton installed. The OS runs great and I have absolutely no screen tearing when I move my windows around, scroll in my web browser, work in Gimp or Photoshop (wine) or even when I play very graphic demanding games, like Metro Last Light, Euro Truck Driver 2 and so on. There's not a tiny bit of tearing to see, but as soon as I play videos, in xbmc, vlc or parole media player the tearing begins (strangely enough this does not apply to youtube videos). I followed all available workarounds on askubuntu and the ubuntu forum,like the 50-xserver-command.conf, startx /etc/X11/Xsession /usr/bin/xbmc-standalone -- -bs or libsdl1.2debian fix and many more, but to no avail. I also tried the Open Source Nouveau display drivers as well, but for some odd reason they don't work so great on my system or at least with my graphics card. Even with Compton installed and configured, I have an extreme amount of screen tearing, as soon as I switch to the proprietary Nvidia drives the screen tearing is gone completely, except for the video playback with xbmc, vlc or parole media player. System info for your reference: OS: Xubuntu 14.04 Linux-x86_64 - Processor: Intel Core i7-4770S CPU @ 3.10GHz - Ram: 16 GB - GeForce GT 750M 1024 MB - Nvidia Driver: 331.38 Has anyone experienced such an odd issue or do you have any advice on how I could fix this? I would appreciate any help! Have a nice day!

• Is '@' Error Suppression a Valid Technique for Testing for an Optional Array Key?

  - by MikeSchinkel

  Rarst and I were debating offline about the use of the '@' error suppression operator in PHP, specifically for use to test for existence of "optional" array keys, i.e. array keys that are being used as a switch here a their lack of existence in the array is functionally equivalent to the array having the key with a value equaling false. Here is pseudo-code for this scenario: function do_something( $args = array() ) { if ( @$args['switch'] ) { // Do something with this switch } // continue on... } vs. this approach: function do_something( $args = array() ) { if ( ! empty( $args['switch'] ) && $args['switch'] ) { // Do something with this switch } // continue on... } Of course in most use-cases, suppressing errors would not be A Good Thing(tm). However in this use-case where an array is passed with an optional element, it seems to me that it is actually a very good technique but I could be wrong and would like to hear other's opinions on the subject before I make up my mind. I do know that there are alleged performance hits for using the former approach but I'd like to know how they compare with the alternative and if they performance hits really matter in real world scenarios? P.S. I decided to post this because, after debating this offline with Rarst, he asked a more general question here on Programmers but didn't actually give a detailed example of the specific use-case we were debating. And since I'm pretty sure he'll want to use the out-of-context answers on that other question as justification for why the above is "bad" I decided I needed to get opinions on this specific use-case.

• An unexpected pleasure from Windows 8

  - by eddraper

  This post is certainly on the more nuanced side of all the goodness that is Windows 8, but it’s about something that’s really changed my PC usage experience for the better. Besides being a geek and the enjoying all the techno-thrills and chills that go along with sitting in front of a keyboard all day, I really love the forest.  Trees have always been special to me.  The feeling of being in the forest with all the sounds and ambiance, the broken light, the fragrance of the air… it’s paradise to me. As I can’t get there often, due to work, and quite often the heat here in Texas, I’ve found something that can at least partially fill the gap…  When you install Windows 8, you’ll have an app called “Naturespace” from http://www.naturespace.com/ .  It boasts a number of predefined loops in what they call “holographic audio.”  They’re essentially high-tech 3D sound fields recorded in natural environments. After checking them out, I really liked the sound of the “Daybreak” selection: A great benefit is that you don’t have to be in Metro/Modern/Windows App Store mode, in order to keep the sound playing.  To start the day, I click on Daybreak, start it, then go back to the desktop and fire up VS, Chrome, etc. As I work and play, I’m surrounded by this delightful background ambiance which relaxes me and puts my mind at ease. Give it a try.  I think you’ll like it.  And no, you don’t need ear buds or headphones to get the benefit.

• Switch vs Polymorphism when dealing with model and view

  - by Raphael Oliveira

  I can't figure out a better solution to my problem. I have a view controller that presents a list of elements. Those elements are models that can be an instance of B, C, D, etc and inherit from A. So in that view controller, each item should go to a different screen of the application and pass some data when the user select one of them. The two alternatives that comes to my mind are (please ignore the syntax, it is not a specific language) 1) switch (I know that sucks) //inside the view controller void onClickItem(int index) { A a = items.get(index); switch(a.type) { case b: B b = (B)a; go to screen X; x.v1 = b.v1; // fill X with b data x.v2 = b.v2; case c: go to screen Y; etc... } } 2) polymorphism //inside the view controller void onClickItem(int index) { A a = items.get(index); Screen s = new (a.getDestinationScreen()); //ignore the syntax s.v1 = a.v1; // fill s with information about A s.v2 = a.v2; show(s); } //inside B Class getDestinationScreen(void) { return Class(X); } //inside C Class getDestinationScreen(void) { return Class(Y); } My problem with solution 2 is that since B, C, D, etc are models, they shouldn't know about view related stuff. Or should they in that case?

• Data transfer between "main" site and secured virtual subsite

  - by Emma Burrows

  I am currently working on a C# ASP.Net 3.5 website I wrote some years ago which consists of a "main" public site, and a sub-site which is our customer management application, using forms-based authentication. The sub-site is set up as a virtual folder in IIS and though it's a subfolder of "main", it functions as a separate web app which handles CRUD access to our customer database and is only accessible by our staff. The main site currently includes a form for new leads to fill in, which generates an email to our sales staff so they can contact them and convince them to become customers. If that process is successful, the staff manually enter the information from the email into the database. Not surprisingly, I now have a new requirement to feed the data from the new lead form directly into the database so staff can just check a box for instance to turn the lead into a customer. My question therefore is how to go about doing this? Possible options I've thought of: Move the new lead form into the customer database subsite (with authentication turned off). Add database handling code to the main site. (No, not seriously considering this duplication of effort! :) Design some mechanism (via REST?) so a webpage outside the customer database subsite can feed data into the customer database How to organise the code for this situation, preferably with extensibility in mind, and particularly are there any options I haven't thought of?

• How do you cope with change in open source frameworks that you use for your projects?

  - by Amy

  It may be a personal quirk of mine, but I like keeping code in living projects up to date - including the libraries/frameworks that they use. Part of it is that I believe a web app is more secure if it is fully patched and up to date. Part of it is just a touch of obsessive compulsiveness on my part. Over the past seven months, we have done a major rewrite of our software. We dropped the Xaraya framework, which was slow and essentially dead as a product, and converted to Cake PHP. (We chose Cake because it gave us the chance to do a very rapid rewrite of our software, and enough of a performance boost over Xaraya to make it worth our while.) We implemented unit testing with SimpleTest, and followed all the file and database naming conventions, etc. Cake is now being updated to 2.0. And, there doesn't seem to be a viable migration path for an upgrade. The naming conventions for files have radically changed, and they dropped SimpleTest in favor of PHPUnit. This is pretty much going to force us to stay on the 1.3 branch because, unless there is some sort of conversion tool, it's not going to be possible to update Cake and then gradually improve our legacy code to reap the benefits of the new Cake framework. So, as usual, we are going to end up with an old framework in our Subversion repository and just patch it ourselves as needed. And this is what gets me every time. So many open source products don't make it easy enough to keep projects based on them up to date. When the devs start playing with a new shiny toy, a few critical patches will be done to older branches, but most of their focus is going to be on the new code base. How do you deal with radical changes in the open source projects that you use? And, if you are developing an open source product, do you keep upgrade paths in mind when you develop new versions?

• Career opportunities for mid-20 .Net developer

  - by Valera Kolupaev

  Recently, I have moved to Toronto and started exploring career opportunities here. My first impressions about .net developer/architect career are really controversial. Here options that comes to my mind right now: Grow as a developer, lead and solution architect in large and well-known company, like Logitech or IBM. Doing .net development medium size (10-30) software shops Joining some start-up guys First one, seems very bureaucratic with kills all programming fun, that is such valuable to me. And there is not a lot of start ups, that are based on MS technology stack. Good mid-size company seems like a best fit to me, since I can have a lot of fun, doing new projects. Previously I have been working at large (5000+) outsourcing provider as a .Net developer. I was kind of a 'vanilla' time, because our team were always doing massive scale projects from scratch, on latest .Net stack. I would really appreciate if you share pros and cons of path, that you have chosen and what you value most in your current project. I'll start: Pros for Mid-size You are really close to business and application consumers, without all bureaucratic papers Cons It seems, that career oportunities of vertical growth is rather limited, once I have to switch to my own company or join development team of some big players.

• Non-Profit Technololgy for Non-Profits?

  - by TomJ

  I've been looking around for a way to give back to the community, but I haven't found my right fit yet, so an idea came to mind: A non-profit technology "company" that targets non-profits. Do these exist? I've been doing some google searches and can only find software that is targeted for non-profits that is created by for-profit companies or that charges what I believe to be an outrages amount, conferences directed towards non-profits and technology they may use -- or articles complaining about the digital divide and how non-profits view technology as key but dont have the funds or the knowledge to employ it. Pseudo "Business Model" An open source 501(3)(c) organization that targets directly targets non-profits to fill the "digital divide." Most services would be free and consulting fees would be charged for customization. Donations would be accepted and government grants would be sought after. This would enable non-profits to keep pace with the for-profits in the technology sector, but at little to no cost. Perhaps the first "industry" to be targeted would be those that fill key social needs like unemployment, or food banks.

• Which is the best free ide/plugin for struts2?

  - by shahensha

  Hello friends, I have just learnt struts 2 and now I have taken up a full fledged project in it. I learnt the basics of struts 2 in Netbeans with it's struts2 plugin. But I am not at all happy with it, as it is very basic and I end up doing most of the work. It is obviously better than plain-vanilla text editor, but still not at all near to what netbeans provides for springs and hibernate. I know because netbeans provides native support for springs and hibernate, it is meant to be better. I don't mind changing my IDE if i get better support for struts2! So my questions are Please list all the free IDEs where native support for struts2 is provided. And if possible please compare them. Please list all the plugins that are available for eclipse for struts2 development. I have heard there are better plugins in eclipse. Also, if there are better plugins in any other IDE (other than netbeans or eclipse of course), please list them giving links. Please give me some tips which I'll need before starting a full blown project in Struts2. I haven't worked on any project on Struts2. I have just finished reading Struts 2 in Action of Manning publications. Thanking you in advance! regards shahensha

• From simple physics with a ball, to a more complicated shape

  - by Maximus

  Hello fellow game devs and stack overflowers... I recently made a transition from OpenGL ES 1.1 to 2.0 (on Android via NDK) and things are going well so far. I'm working on doing a dice rolling application (gaming dice up to 20 sided, not just regular 6 sided die) as a way to learn more about how physics is implemented in a gaming environment. I've explored implementing existing engine options (such as Bullet) and I don't think I need to implement something quite so sophisticated. I've found several tutorials that handle a lot of the general physics involved with initial trajectory, velocity, angle of contact and reflection angle, etc. I'm confident that I'd be able to implement ball-like behavior without much trouble. My question lies in when I attempt to make the interaction of the die shape with another surface more "realistic," for example... the die strikes the floor surface at such an angle where only one corner makes contact with the floor. In my mind, the center of gravity of the object would play a part in determining how the die bounces away, possibly even spinning it it faster, etc... but I am not sure what the actual math involved is. Are there any recommended resources for getting into this level of detail? Initial searches haven't turned up much... Thanks to everyone in the community, -Jeremiah

• Wifi not working on Acer Aspire One D270

  - by Dani

  brand new baby linux user here, never used Ubuntu or any other linux OS before, so be gentle and use short words! I installed Ubuntu 12.04 on my new Acer Aspire One D270-F61C/KF netbook (it's a Japanese computer which had Japanese windows preinstalled, and I decided to take the plunge and try Ubuntu because English Windows costs the earth and stars). Wifi isn't working; I enter my wireless password, it tries to connect for a while, then asks for my password again. And KEEPS ASKING, every few minutes. Wired connection works fine. Wireless card is a Broadcom BCM4313; I have the "additional drivers" checked and installed (I tried unchecking and then reinstalling them in case that would help, no joy, and now my home wifi connection isn't showing up in the list of available connections, argh). I've done a lot of googling and I gather there's a lot of issues with Broadcom cards, but some of the answers are for earlier ubuntu builds and many of them are a bit confusing for a new user. I gather I need to try installing some new drivers other than the proprietary ones provided, but I'm having trouble figuring out how that's done. Anyone got some simple, step by step instructions for me? Please bear in mind, TOTAL N00B. (EDIT): OKAY, got it fixed finally; after suggestions on the Ubuntu forums and messing around with drivers, what finally worked was installing Wicd. Not... using Wicd, for some reason, just installing it fixed it. ...I CHOOSE NOT TO QUESTION IT.

• Drupal 7 Advice Needed: "Portal" Creation

  - by WernerCD

  Question: What is the best game plan for building what I want. I'm rebuilding the company intranet and am trying to get our "Portals" system re-created in Drupal. I'm trying to learn Panels, because thats what I think would do this, but I just can't seem to get it working. Menu at top, drop down lists for various webpages, tools, internal applications... and Department Portals. When you click on a department portal, you get the same menu at top... and on the main part of the page you have a menu on the left, with content on the right. Menu stays on the left, content loads next to it. Each Portal has its own menu and content (least of which is "Home"). Ultimately, I'd like to be able to say - users with role "Foo" can add/edit/delete Portal Bar. - Each Portal starts with a "Home" - Each Portal has its own Menu tree's. (Picture 2 above has a < ul for video tutorials that would be a second level menu. So more than one deep.) - Content on the right side of the portal should be flexible (Video, PDF via fileviewer, etc) - Portal Bar should have its own Folder to contain it's content. I'm trying to do this in Panels, but I can't seem to put the pieces together in my mind and in practice. I hope I'm making sense, because the dizzying array of stuff is killing me lol.

• Recording custom variables to identify individual users with Google Analytics

  - by mrtsherman

  I have been asked by our marketing department to add Google Analytics custom variable tracking to my company's website. As the website uses server side includes, modifications to the tracking tag roll out globally - maintenance is therefore a headache! So, if I add the following code (keeping in mind SSI so every page has the same code): // visitor level tracking, id = 12345 // Record a unique id for each visitor. When they return also track this id _gaq.push(['_setCustomVar', 1, 'id', '12345', 1]); // page level tracking // If the user signs up for our newsletter we set newsletter to true // Each page they subsequently visit should also mark this as true _gaq.push(['_setCustomVar', 1, 'newsletter', 'true', 1]); I don't use GA and the marketing people don't use custom variables, so we don't actually know how or if this will work. Therefore my questions are:- Do I want Page, Session or Visitor level tracking? What happens when the same code is used on every page? Can GA 'overwrite' a setting. For example, if I set newsletter to true on page X and then user navigates to page Y, will the variable also be marked there?

• Restful Java based web services in json + html5 and javascript no templates (jsp/jsf/freemarker) aka fat/thick client

  - by Ismail Marmoush

  I have this idea of building a website which service JSON data through restful services framework. And will not use any template engines like jsp/jsf/freemarker. Just pure html5 and Javascript libs. What do you think of the pros and cons of such design ? Just for elaboration and brain storming a friend of mine argued with the following concerns: sounds like gwt this way you won't have any control over you service api for example say you wanna charge the user per request how will you handle it? how will you control your design and themes? what about the 1st request the browser make? not easy with this all of the user's requests will come with "Accept" header "application/json" how will you separate browser from abuser? this way all of your public apis will be used by third party apps abusively and you won't be able to lock it since you won't be able to block the normal user browser We won't use compiled html anyway but may be something like freemarker and in that case you won't expose any of your json resources to the unauthorized user but you will expose all the html since any browser can access them all the well known 1st class services do this can you send me links to what you've read? keep in mind the DOM based XSS it will be a nightmare ofc, if what you say is applicable.

• Working with multiple interfaces on a single mock.

  - by mehfuzh

  Today , I will cover a very simple topic, which can be useful in cases we want to mock different interfaces on our expected mock object.  Our target interface is simple and it looks like:   public interface IFoo : IDisposable {     void Do(); } Now, as we can see that our target interface has implemented IDisposable and in normal cases if we have to implement it in class where language rules require use to implement that as well[no doubt about it] and whether or not there can be more complex cases, we want to ensure that rather having an extra call(..As()) or constructs to prepare it for us, we should do it in the simplest way possible. Therefore, keeping that in mind, first we create a mock of IFoo var foo = Mock.Create<IFooDispose>(); Then, as we are interested with IDisposable, we simply do: var iDisposable = foo as IDisposable;   Finally, we proceed with our existing mock code. Considering the current context, we I will check if the dispose method has invoked our mock code successfully.   bool called = false;   Mock.Arrange(() => iDisposable.Dispose()).DoInstead(() => called = true);     iDisposable.Dispose();   Assert.True(called);   Further, we assert our expectation as follows: Mock.Assert(() => iDisposable.Dispose(), Occurs.Once());   Hopefully that will help a bit and stay tuned. Enjoy!!
