• PHP - Internal APIs/Libraries - What makes sense?

  - by Mark Locker

  I've been having a discussion lately with some colleagues about the best way to approach a new project, and thought it'd be interesting to get some external thoughts thrown into the mix. Basically, we're redeveloping a fairly large site (written in PHP) and have differing opinions on how the platform should be setup. Requirements: The platform will need to support multiple internal websites, as well as external (non-PHP) projects which at the moment consist of a mobile app and a toolbar. We have no plans/need in the foreseeable future to open up an API externally (for use in products other than our own). My opinion: We should have a library of well documented native model classes which can be shared between projects. These models will represent everything in our database and can take advantage of object orientated features such as inheritance, traits, magic methods, etc. etc. As well as employing ORM. We can then add an API layer on top of these models which can basically accept requests and route them to the appropriate methods, translating the response so that it can be used platform independently. This routing for each method can be setup as and when it's required. Their opinion: We should have a single HTTP API which is used by all projects (internal PHP ones or otherwise). My thoughts: To me, there are a number of issues with using the sole HTTP API approach: It will be very expensive performance wise. One page request will result in several additional http requests (which although local, are still ones that Apache will need to handle). You'll lose all of the best features PHP has for OO development. From simple inheritance, to employing the likes of ORM which can save you writing a lot of code. For internal projects, the actual process makes me cringe. To get a users name, for example, a request would go out of our box, over the LAN, back in, then run through a script which calls a method, JSON encodes the output and feeds that back. That would then need to be JSON decoded, and be presented as an array ready to use. Working with arrays, as appose to objects, makes me sad in a modern PHP framework. Their thoughts (and my responses): Having one method of doing thing keeps things simple. - You'd only do things differently if you were using a different language anyway. It will become robust. - Seeing as the API will run off the library of models, I think my option would be just as robust. What do you think? I'd be really interested to hear the thoughts of others on this, especially as opinions on both sides are not founded on any past experience.

• OAuth with RestSharp in Windows Phone

  - by midoBB

  Nearly every major API provider uses OAuth for the user authentication and while it is easy to understand the concept, using it in a Windows Phone app isn’t pretty straightforward. So for this quick tutorial we will be using RestSharp for WP7 and the API from getglue.com (an entertainment site) to authorize the user. So the first step is to get the OAuth request token and then we redirect our browserControl to the authorization URL private void StartLogin() {   var client = new RestClient("https://api.getglue.com/"); client.Authenticator = OAuth1Authenticator.ForRequestToken("ConsumerKey", "ConsumerSecret"); var request = new RestRequest("oauth/request_token"); client.ExecuteAsync(request, response => { _oAuthToken = GetQueryParameter(response.Content, "oauth_token"); _oAuthTokenSecret = GetQueryParameter(response.Content, "oauth_token_secret"); string authorizeUrl = "http://getglue.com/oauth/authorize" + "?oauth_token=" + _oAuthToken + "&style=mobile"; Dispatcher.BeginInvoke(() => { browserControl.Navigate(new Uri(authorizeUrl)); }); }); } private static string GetQueryParameter(string input, string parameterName) { foreach (string item in input.Split('&')) { var parts = item.Split('='); if (parts[0] == parameterName) { return parts[1]; } } return String.Empty; } Then we listen to the browser’s Navigating Event private void Navigating(Microsoft.Phone.Controls.NavigatingEventArgs e) { if (e.Uri.AbsoluteUri.Contains("oauth_callback")) { var arguments = e.Uri.AbsoluteUri.Split('?'); if (arguments.Length < 1) return; GetAccessToken(arguments[1]); } } private void GetAccessToken(string uri) { var requestToken = GetQueryParameter(uri, "oauth_token"); var client = new RestClient("https://api.getglue.com/"); client.Authenticator = OAuth1Authenticator.ForAccessToken(ConsumerKey, ConsumerSecret, _oAuthToken, _oAuthTokenSecret); var request = new RestRequest("oauth/access_token"); client.ExecuteAsync(request, response => { AccessToken = GetQueryParameter(response.Content, "oauth_token"); AccessTokenSecret = GetQueryParameter(response.Content, "oauth_token_secret"); UserId = GetQueryParameter(response.Content, "glue_userId"); }); } Now to test it we can access the user’s friends list var client = new RestClient("http://api.getglue.com/v2"); client.Authenticator = OAuth1Authenticator.ForProtectedResource(ConsumerKey, ConsumerSecret, GAccessToken, AccessTokenSecret); var request = new RestRequest("/user/friends"); request.AddParameter("userId", UserId,ParameterType.GetOrPost); // request.AddParameter("category", "all",ParameterType.GetOrPost); client.ExecuteAsync(request, response => { TreatFreindsList(); }); And that’s it now we can access all OAuth methods using RestSharp.

• Advice on how to build html5 basic tile game (multi player, cross device)

  - by Eric

  I just read http://buildnewgames.com/real-time-multiplayer/ which explains the fundamentals and bets practices to build a massive real time multiplayer html5 game. My question is however given the “simplicity” of the game I need to build (simple kind of scratch game where you find or not something behind a tile), do I really need complex tools (canvas or node.js for example) ? The game The gamestakes place with a picture of our office as a background (tilemap). For HR purpose, we wish to create the following game fore employees: each day they can come to the website and click on a certain number of tiles (3 max per day) and find behind it motivation advice and interesting facts about the company. The constraints and rules the screen is divided into isometric 2D square tiles. There are basically an image (photograph of our office) number of tiles on the screen game: about 10,000 to much more (with scroll , see below) the players can scroll in 4 directions there are only 2 types of tiles: already open and closed player can open tiles that have not been yet open by other players there is no path for players : any player can click on any tile on the screen at any moment (if it’s not already done by another player) 2 players can’t be on the same tile at the same moment (or if they can, I’ll have to manage to see which one clicked on it first) only one type of player (all with similar roles), no weapon, no internal score… very simple game. no complex physics (collision only occurs if 2 players are on the same tile) The target I need to achieve: cross device, cross browsers high performance reaction (subsecond reactions) average nb of players per hour: up to 10K players per hour (quite high indeed but it’s because we aim at proving our case for the game to our business unit) So what I would like to know: 2D Tiled map: Do I need tiledmapeditor or can I enable me split the screen like here ? should I use canvas or plain html/css could be sufficient for my need? do I need a game engine/framework such as melon.js or crafty./js ? (even if the game play is extremely basic, I do need mouse and touché device support, mouse emulations on touch devices…) or ca I easily/quickly do it without? for my constraints and targets, should I use CPU acceleration ? for my constraints and targets, should I use web workers ? for the database, for a massively real time game should I avoid to put the current locations of player in MySQL as i feel it might slow me down. What kind of DB should I implement ? Thanks for your help !

• How can we unify business goals and technical goals?

  - by BAM

  Some background I work at a small startup: 4 devs, 1 designer, and 2 non-technical co-founders, one who provides funding, and the other who handles day-to-day management and sales. Our company produces mobile apps for target industries, and we've gotten a lot of lucky breaks lately. The outlook is good, and we're confident we can make this thing work. One reason is our product development team. Everyone on the team is passionate, driven, and has a great sense of what makes an awesome product. As a result, we've built some beautiful applications that we're all proud of. The other reason is the co-founders. Both have a brilliant business sense (one actually founded a multi-million dollar company already), and they have close ties in many of the industries we're trying to penetrate. Consequently, they've brought in some great business and continue to keep jobs in the pipeline. The problem The problem we can't seem to shake is how to bring these two awesome advantages together. On the business side, there is a huge pressure to deliver as fast as possible as much as possible, whereas on the development side there is pressure to take your time, come up with the right solution, and pay attention to all the details. Lately these two sides have been butting heads a lot. Developers are demanding quality while managers are demanding quantity. How can we handle this? Both sides are correct. We can't survive as a company if we build terrible applications, but we also can't survive if we don't sell enough. So how should we go about making compromises? Things we've done with little or no success: Work more (well, it did result in better quality and faster delivery, but the dev team has never been more stressed out before) Charge more (as a startup, we don't yet have the credibility to justify higher prices, so no one is willing to pay) Extend deadlines (if we charge the same, but take longer, we'll end up losing money) Things we've done with some success: Sacrifice pay to cut costs (everyone, from devs to management, is paid less than they could be making elsewhere. In return, however, we all have creative input and more flexibility and freedom, a typical startup trade off) Standardize project management (we recently started adhering to agile/scrum principles so we can base deadlines on actual velocity, not just arbitrary guesses) Hire more people (we used to have 2 developers and no designers, which really limited our bandwidth. However, as a startup we can only afford to hire a few extra people.) Is there anything we're missing or doing wrong? How is this handled at successful companies? Thanks in advance for any feedback :)

• Powerful Lessons in Data from the Presidential Election

  - by Christina McKeon

  Now that we’ve had a few days to recover from the U.S. presidential election, it’s a good time to take a step back from politics and look for the customer experience lessons that we can take away. The most powerful lesson is that when you know more about your base, you will have an advantage over your competition. That advantage will translate into you winning and your competition losing. Michael Scherer of TIME was given access to Obama’s data analysts two days before the election. His account is documented in Inside the Secret World of the Data Crunchers Who Helped Obama Win. What we learned from Scherer’s inside view is how well Obama’s team did in getting the right data, analyzing it, and acting on it. This data team recognized how critical it was to break down data silos within the campaign. As Scherer noted, they created “a single system that merged information from pollsters, fundraisers, field workers, consumer databases, and social-media and mobile contacts with the main Democratic voter files in the swing states.” The Obama analysis was so meticulous that they knew which celebrity and which type of celebrity event would help them maximize campaign contributions. With a single system, their data models became more precise. They determined which messages were more successful with specific demographic groups and that who made the calls mattered. Data analysis also led to many other changes in Obama’s campaign including a new ad buying strategy, using social media and applications to tap into supporters’ friends, and using new social news sites. While we did not have that same inside view into Romney’s campaign, much of the post-mortem coverage indicates that Romney’s team did not have the right analysis. As Peter Hamby of CNN wrote in Analysis: Why Romney Lost, “Romney officials had modeled an electorate that looked something like a mix of 2004 and 2008….” That historical data did not account for the changing demographics in the U.S. Does your organization approach data like the Obama or Romney team? Do you really know your base? How well can you predict what is going to happen in your business? If you haven’t already put together a strategy and plan to know more, this week’s civics lesson is a powerful reason to do it sooner rather than later. Your competitors are probably thinking the same thing that you are!

• Software Architecture Analysis Method (SAAM)

  Software Architecture Analysis Method (SAAM) is a methodology used to determine how specific application quality attributes were achieved and how possible changes in the future will affect quality attributes based on hypothetical cases studies. Common quality attributes that can be utilized by this methodology include modifiability, robustness, portability, and extensibility. Quality Attribute: Application Modifiability The Modifiability quality attribute refers to how easy it changing the system in the future will be. This to me is a very open-ended attribute because a business could decide to transform a Point of Sale (POS) system in to a Lead Tracking system overnight. (Yes, this did actually happen to me) In order for SAAM to be properly applied for checking this attribute specific hypothetical case studies need to be created and review for the modifiability attribute due to the fact that various scenarios would return various results based on the amount of changes. In the case of the POS change out a payment gateway or adding an additional payment would have scored very high in comparison to changing the system over to a lead management system. I personally would evaluate this quality attribute based on the S.O.I.L.D Principles of software design. I have found from my experience the use of S.O.I.L.D in software design allows for the adoption of changes within a system. Quality Attribute: Application Robustness The Robustness quality attribute refers to how an application handles the unexpected. The unexpected can be defined but is not limited to anything not anticipated in the originating design of the system. For example: Bad Data, Limited to no network connectivity, invalid permissions, or any unexpected application exceptions. I would personally evaluate this quality attribute based on how the system handled the exceptions. Robustness Considerations Did the system stop or did it handle the unexpected error? Did the system log the unexpected error for future debugging? What message did the user receive about the error? Quality Attribute: Application Portability The Portability quality attribute refers to the ease of porting an application to run in a new operating system or device. For example, It is much easier to alter an ASP.net website to be accessible by a PC, Mac, IPhone, Android Phone, Mini PC, or Table in comparison to desktop application written in VB.net because a lot more work would be involved to get the desktop app to the point where it would be viable to port the application over to the various environments and devices. I would personally evaluate this quality attribute based on each new environment for which the hypothetical case study identifies. I would pay particular attention to the following items. Portability Considerations Hardware Dependencies Operating System Dependencies Data Source Dependencies Network Dependencies and Availabilities  Quality Attribute: Application Extensibility The Extensibility quality attribute refers to the ease of adding new features to an existing application without impacting existing functionality. I would personally evaluate this quality attribute based on each new environment for the following Extensibility  Considerations Hard coded Variables versus Configurable variables Application Documentation (External Documents and Codebase Documentation.) The use of Solid Design Principles

• New grad; To overcome complete lack of experience, should I ditch a creative pet project in lieu of one that would demonstrate more applicable skills?

  - by Hart Simha

  I am currently working on a project on github that I think would be a good demonstration of my initiative, creativity and enthusiasm. It is an educational game I am developing in pygame that enables the user to learn to improve their development productivity by using vim, specifically with python, though learning to code faster with vim should be transferable to any language. I think this is something that might have a mass appeal and benefit to a lot of people in a measurable way. -However- I am graduating from college in a month (my degree is computer science with a minor in English), with no experience that is relevant to helping me get any kind of job in the field, and a gpa that doesn't tout my merits. I could pursue a career in game development, but it's not necessarily what I'm most interested in, and see myself applying to startups around the country. To the places I am looking at applying, showing that I have experience with pygame is going to be largely irrelevant, except in demonstration of my ability to code, period. A lot of skills that ARE more marketable, such a data modeling, GIS, mobile application, development, javascript, .net framework, and various web development technologies, are not going to be showcased by this project (on the upside, employers do like to see familiarity with git and python). I'm wondering if I should sink all my free time in the next couple of months into this project, since I'm motivated and interested in it, and if the value of being able to demonstrate ambition and 'good ideas' (for lack of a better term, and in my own opinion) will compensate for the absence of demonstrating more sought-after skills. I am probably at a point where I should either commit fully to this project now, or put it on the backburner in favor of something else, and I am leaning towards continuing with what I am already working on, because I think it's a great idea, and something achievable to me with enough dedication over the next couple months. But the most important thing to me is being able to get a job out of college, which I am exceedingly concerned about as the professional landscape which I am navigating for the first time is a lot more intimidating than I could have anticipated, with almost every job (even short-term contract positions) requiring years of experience which I lack. So in brief, the common denominator to answering the question "How can I overcome experience requirements for a job" seems to be "Show off your own project." I want to know WHICH project I should work on to best increase my chances of getting a job out of college, keeping in mind that I have no experience. I believe this question is applicable to any new grad that lacks demonstrable experience.

• How / Where can I host my Java web application? [closed]

  - by Huliax

  Possible Duplicate: How to find web hosting that meets my requirements? In case you want to skip to the crux of my inquiry just read the bold type. I just finished my CS degree (at 39 years old :-)). For my final project I designed and built a system that can provide local positioning / location awareness to mobile wifi devices (only have Android client thus far). The server receives data from clients, processes it, and responds to the clients with a messages containing information about their respective locations. I would like to continue the project (perhaps release as open source but that is a different discussion). Thus far my server application has been running on the CS department's hardware where I could pretty much do whatever I wanted. I'm getting kicked off that system in a few weeks so I have to find a new home for my server application. I need a host that will let me run my Java server (along w/ mySQL db) -- preferably on the cheap since I haven't yet got a job. I have very little experience with the "real world" of web development / hosting. I'm having trouble figuring out what kind of hosting service will let me run my application as is. If that turns out to be a tall order then I need to know what my options are for changing thing so that I can get up and running with some hosting. As an aside, I'm also researching whether or not I should rewrite this in a different language. Trying to figure out if there is a substantially better (for whatever reason) one for what I'm doing. This might also potentially have a bearing on my hosting needs. One possibility is to write the server in something more widely accepted by hosting services. I have been searching for answers to my question and haven't found quite what I'm looking for. Part of the problem might be that I don't know exactly what terminology to use. If there is a good answer to this question elsewhere please feel free to point me towards it. Thanks for help / advice.

• How to do proper Alpha in XNA?

  - by Soshimo

  Okay, I've read several articles, tutorials, and questions regarding this. Most point to the same technique which doesn't solve my problem. I need the ability to create semi-transparent sprites (texture2D's really) and have them overlay another sprite. I can achieve that somewhat with the code samples I've found but I'm not satisfied with the results and I know there is a way to do this. In mobile programming (BREW) we did it old school and actually checked each pixel for transparency before rendering. In this case it seems to render the sprite below it blended with the alpha above it. This may be an artifact of how I'm rendering the texture but, as I said before, all examples point to this one technique. Before I go any further I'll go ahead and paste my example code. public void Draw(SpriteBatch batch, Camera camera, float alpha) { int tileMapWidth = Width; int tileMapHeight = Height; batch.Begin(SpriteSortMode.Texture, BlendState.AlphaBlend, SamplerState.PointWrap, DepthStencilState.Default, RasterizerState.CullNone, null, camera.TransformMatrix); for (int x = 0; x < tileMapWidth; x++) { for (int y = 0; y < tileMapHeight; y++) { int tileIndex = _map[y, x]; if (tileIndex != -1) { Texture2D texture = _tileTextures[tileIndex]; batch.Draw( texture, new Rectangle( (x * Engine.TileWidth), (y * Engine.TileHeight), Engine.TileWidth, Engine.TileHeight), new Color(new Vector4(1f, 1f, 1f, alpha ))); } } } batch.End(); } As you can see, in this code I'm using the overloaded SpriteBatch.Begin method which takes, among other things, a blend state. I'm almost positive that's my problem. I don't want to BLEND the sprites, I want them to be transparent when alpha is 0. In this example I can set alpha to 0 but it still renders both tiles, with the lower z ordered sprite showing through, discolored because of the blending. This is not a desired effect, I want the higher z-ordered sprite to fade out and not effect the color beneath it in such a manner. I might be way off here as I'm fairly new to XNA development so feel free to steer me in the correct direction in the event I'm going down the wrong rabbit hole. TIA

• Wired connection not being recognized

  - by maxifick

  I'm on Ubuntu Maverick (10.10). I've read a few threads regarding wired connection problems, but haven't found a solution yet. The problem appears after I connect to a wireless network. When I disconnect wireless and plug in an internet cable, the wired connection is not recognized at all. Even the socket appears dead (there are no diodes flashing). The only solution so far seems to be restarting the computer. Network Manager then tries to connect to a Wi-Fi, but the wired connection is listed and working. I've tried sudo restart network-manager, but that doesn't solve anything. After a while, available wireless networks start appearing, but the wired still doesn't. Any ideas? Thanks in advance. Edit: Here is the dmesg output after switching off Wi-Fi and then plugging the internet cable. [18200.623543] Restarting tasks ... done.

• iOS app with a lot of text

  - by rdurand

  I just asked a question on StackOverflow, but I'm thinking that a part of it belongs here, as questions about design pattern are welcomed by the faq. Here is my situation. I have developed almost completely a native iOS app. The last section I need to implement is all the rules of a sport, so that's a lot of text. It has one main level of sections, divided in subsections, containing a lot of structured text (paragraphs, a few pictures, bulleted/numbered lists, tables). I have absolutely no problem with coding, I'm just looking for advice to improve and make the best design pattern possible for my app. My first shot (the last one so far) was a UITableViewController containing the sections, sending the user to another UITableViewController with the subsections of the selected section, and then one strange last UITableViewController where the cells contain UITextViews, sections header help structure the content, etc. What I would like is your advice on how to improve the structure of this section. I'm perfectly ready to destroy/rebuild the whole thing, I'm really lost in my design here.. As I said on SO, I've began to implement a UIWebView in a UIViewController, showing a html page with JQuery Mobile to display the content, and it's fine. My question is more about the 2 views taking the user to that content. I used UITableViewControllers because that's what seemed the most appropriate for a structured hierarchy like this one. But that doesn't seem like the best solution in term of user experience.. What structure / "view-flow" / kind of presentation would you try to implement in my situation? As always, any help would be greatly appreciated! Just so you can understand better the hierarchy, with a simple example : -----> Section 1 -----> SubSection 1.1 -----> Content | -----> SubSection 1.2 -----> Content | -----> SubSection 1.3 -----> Content | | | UINavigationController -------> Section 2 -----> SubSection 2.1 -----> Content | -----> SubSection 2.2 -----> Content | -----> SubSection 2.3 -----> Content | -----> SubSection 2.4 -----> Content | -----> SubSection 2.5 -----> Content | -----> Section 3 -----> SubSection 3.1 -----> Content -----> SubSection 3.2 -----> Content |------------------| |--------------------| |-------------| 1 UITableViewController 3 UITableViewControllers 10 UIViewControllers (3 rows) (with different with a UIWebView number of rows)

• How can I improve the battery life under 12.04 on my Inspiron 14z? [duplicate]

  - by cfogelberg

  This question already has an answer here: Tips to extend battery life for laptops and notebooks 24 answers How do I improve the battery life of my Inspiron 14z under Ubuntu 12.04? This laptop gets 4-5 hours of battery life using Windows (e.g. here). I've removed Windows, installed Ubuntu 12.04 and the initial battery life was only 2 hours. With some tweaks (described below) it's still only ~2.5 hours. For reference, the laptop is the latest model of the 14z: i5-3337U processor 32GB MSATA, 500GB HDD (5400rpm) AMD Radeon HD7570M graphics card I have put ext4 partitions on both the SSD and the HDD, and have mounted / to the SSD and /home to the HDD. I also put a 24gb linux swap partition at the start of the HDD, though I figure this won't be used all that much (the laptop has 8gb of RAM). After googling around and reading Ask Ubuntu and other sites extensively, I have done the following steps, and they have improved the battery life ~30 minutes (exact improvement not clear, but battery life is still nowhere near 4-5 hours). Installed Jupiter (and set Performance to "Power Saving") Installed laptop-mode-tools cat /proc/sys/vm/laptop_mode now outputs 5 (previously it output 0) But it's not clear that this will help: AskUbuntu question Turned down the brightness of my screen from full to 1/3 Other things I have heard about but have not tried for fear of frying the laptop or my linux install: Add "pcie_aspm=force" at the end of the line with "quiet splash" in /boot/grub/grub.cfg Enable ALPM, but it may already be enabled in 12.04? Enable i915 framebuffer compression Use a propietary driver for the graphics card? Turn off the graphics card? (what would happen if I relied on the internal Intel bridge?) Use TLP? Spin down the HDD more aggressively (howto, but I think laptop-mode-tools does this already) The only other thing I've noticed is that plastic just above the F5, F6 and F7 keys gets really hot. According to Jupiter my CPU temperature is only 69 celsius and the System Monitor shows CPU load at 7% so I don't think it's the CPU. Maybe it's the graphics card? Also, I've set up MongoDB and LAMP on the machine as well. When I run powertop MongoDB is high in the list, but I'm not sure if that's relevant to battery life because I'm not actually doing anything with MongoDB most of the time.

• Should I use my own public API on my site (via JS)?

  - by newboyhun

  First of all, this question is far more different other 'public api questions' like this: Should a website use its own public API?, second, sorry for my English. You can find the question summarized at the bottom of this question. What I want to achieve is a big website with a public api, so who like programming (like me) and likes my website, can replicate my website's data with a much better approach (of course with some restrictions). Almost everything could be used by the public API. Because of this, I was thinking about making the whole website AJAX driven. There would be parts of the API which would be limited only to my website (domain), like login, registering. There would be only an INTERFACE on the client side, which would use the public and private API to make this interface working. The website would be ONLY CLIENT SIDE, well, I mean, the website would only use AJAX to use the api. How do I imagine this? The website would be like a mobile application, the application only sending a request to a webserver, which returns a json, the application parses it, and uses it to advance in the application. (e.g.: login) My thoughts: Pros: The whole website is built up by javascript, this means I don't need to transfer the html to the client, saving bandwidth. (I hope so) Anyone can use up the data of my website to make their own cool things. (Is this a con or pro? O_O) The public API is always in use, so I can see if there are any error. Cons: Without Javascript the website is unusable. The bad guys easily can load the server with requesting too much data (like Request Per Second 10000), but this can be countered via limiting this with some PHP code and logging. Probably much more work So the question in some words is: Should I build my website around my own api? Is it good to work only on the client side? Is this good for a big website? (e.x.: facebook, yeah facebook is a different story, but could it run with an 'architecture' like this?)

• Want to make RTS strategy game, good starting point...?

  - by NOLANDI

  everybody! I find this community because I did research about game developing topics. So I decide to register on this community and ask for your opinion. I am not begineer in computer stuffs, and I know logic of programming language. I have little knowlegde of C, C++, Started to learn C#...but I was always oriented about other areas of IT. Amateur for game making but not in IT general! I am interested to make RTS strategy video game, isometric camera view (like PC GAME COMMANDOS for example)...so I started to read many books about DirectX, XNA, OpenGL, C#, AI programming...so I want to know where is good starting point for making this game genre. I want to use C# for this project, not C++, since I always had trouble with it, because it is too complicated. I see good oportunity for learning C#, since it has more object-oriented concept, with much less code and easy readible code for writing. Beside of that I know that C++ is the more powerful language until today. So I want to use DirectX and C# for my project. But it will required more time for sure, to learn it. I have trouble with finding books for c# & DirectX (I found just one), but in every next book, it is programming in c++! I read many web sites and they mentioned Slim DX, and in generaly, other articles which I read tells that it is possible to make good game with combination c# and directX, but...I don't have enough information about all this stuffs, so I became confused! It is really hard to have wish to learn c++ from scratch, since I started c# and I like it really...I don't try OpenGL, but I am already familiar with DirectX (some beginning stuffs), and I think that it is good and interesting. So, I decide to choose between maybe Unity3d and XNA first. XNA...hm, it sound that it is not bad solution, but I heard that it is already overcome technology, and I think that it is better to wait with XNA, until I try to make something with DirectX and C#, at first. But I dont know it is possible to make strategy game in XNA?! Maybe I am wrong. I also, find Unity 3D game engine and I find that I could programming there in C#, but many all examples are written in Javascript (Digital tutors videos)...But I generaly have wish to learn it too, because it allows to export games to mobile phones, there a lot of documentations, it is free, etc... I want to find best way to learn C# and DirectX, and make this game, but I dont know if it's possible to combine?! But maybe is good to first try Unity and XNA, because I am beginner?! Thank you all! I am willing to hear your expirience.

• A Windows Update Prevented Live Discs From Working? [migrated]

  - by user88311

  First off I'll state my system specs. Acer Aspire M1100 Windows Vista Home Basic 32bit OEM 2 Gigs of DDR2 ram 160Gig hard drive 2.7Ghz AMD Athlon 64 processor ATI Radeon X1250 Graphics card A few days ago my computer did automatic updates and updated windows defender to KB915597 (Definition 1.135.415.0), After which when shutting down and starting up I would receive BSOD with the information BUGCODE_USE_DRIVER and 0x000000FE (0x00000008, 0x00000006, 0x00000006, 0x877330000) upon where my computer would not start up with any USB devices plugged in and it always require me to run startup repair before it started. Upon when I first started it up and was able to fully boot windows, I had no use of the mouse so I was unable to install the fix that the windows solutions center brought up on my screen, so I restarted again and installed the fix hoping it would cease the problem, it did not. Upoon starting up after installing the fix and restarting I was confronted with the BSOD 0x000000FE (0x00000008, 0x00000006, 0x00000006, 0x83291000) at which I found the startup repair could not fix the problem and I restored, as I most like should have in the first place. After going through that I read that simply installing the latest defender version from the microsoft site had fixed this problem for others, so I did that, to find I still received the BSOD's. So in a attempt to find a fix to the problem I went to the microsoft answers site to try to find a way to fix the problem, there I was told to simply disable defender and reboot to see if that fixed the problem, upon doing this my computer would no longer even startup, when I boot normally I get to just when the loading screen finishes and then my computer restarts and when I run startup repair, it runs for about 15 seconds and then my computer restarts as well. I have tried running ubuntu live discs in order to simply access the drive and simply copy and paste the 2 month old physical backup I have of my C drive to the C drive, but whenever I run the live OS when it gets to the end of the load screen and is about to boot, the computer again restarts, yet if I put in a gparted disc, I am able to boot it fully, although it does not give me access to the file system just partition managing and when I attempt to access the internet through it, the computer once again restarts. So my question is, how could the update and what has happened prevent me from running the live OS's properly?

• MVC Can the model know ANYTHING about the view?

  - by AwDogsGo2Heaven

  I'm working on a game, and without getting into any details I am using MVC "patterns", "rules" or whatever you want to call it to make the game. The view includes everything needed to draw things on the screen, the controller passes input to the model. And the Model contains game logic. Here's my problem, the game is being made for mobile devices that vary in screen sizes. I feel my model needs to know the view size so it can appropriately adjust for it. I've thought about it for a while I could put all the adjustments in the view, but it just seems inefficient to translate the model positioning to the view's needed positioning every time. If the model knows the size it only needed to adjust itself once. So my question is can I pass the view size to the model without 'breaking' MVC? I feel personally they are still decoupled this way because a size is just a number, I could still change the view any time as long as it has a size. But I wanted to get a community response on this because I haven't seen many discussions of MVC being used in a game. (And to be clear I don't want an answer of why I shouldn't use it in a game, but do I break MVC by letting it know the view's size) EDIT - More details on the game's needs and why I wanted to pass the view. Some objects positions need to be set relative to the edge of the screen (such as UI elements) so that they appear relatively in the same place. Sprite sizes are not stretched if the window size is wider such as an IPhone 5 screen. They will just be placed relatively to the screen edge. .If I gave it to the view to handle this, I will need a flag saying that this element is positioned say x number of pixels from TOP BOTTOM RIGHT LEFT. Then allow the view to draw it with that information. Its acceptable, I just wanted to know if there was a better way while still being MVC because it seems this way will be repeating a logic over and over, where as if I knew the view size in the model, I could convert all the relative positions into absolute positions in one run, but with this I have to convert on every update to the screen.

• Trying to find resources to learn how to test software [closed]

  - by Davek804

  First off, yes this is a general question, and I'd be perfectly happy to move this to another portion of SE, but I didn't see a more fitting sub. Basically, I am hoping a more experienced QA tester can come along and really fill in some basics for me. So far, websites seem to be sparse in terms of explaining languages involved, basic practices, etc. So, I'm sorry in advance if this is too general, but towards the end of this post I ask some specific questions if it's just absolutely unacceptable to speak in general terms. I just landed a position as Junior Systems and QA Engineer with a social media startup. Their QA and testing is almost nonexistent, so if I do a good job, I imagine I'll find a lot of bugs and have a secure role in the business. I'm pretty good with the systems aspect of my role, but I need to learn more about the QA and testing aspects. We run hardware that's touchscreen based - the user can use and interact with the devices. So, in terms of my QA role, in the short term, I need to build scripts to test the hardware/software as a 'user' to try to uncover bugs. First off, what language should these scripts be written in? Does anyone have some examples? What about the longer term 'automated testing'? I'm familiar with regression testing as the developer adds in new features, sure, but the 50,000 other types of testing, not so much. Most of our hardware runs dotnet/C# code, with some of the servers running Java - but I don't expect to need to run tests on the Java side at this point. I hope to meet with one developer today and try to get a good idea of the output from the hardware so that I can 'mock' this data that gets sent to servers, to try to bugtest. Eventually, we will be moving the hardware to be closer to where I live and work, so that I can test virtually and on real hardware. So a lot of the bugs we're dealing with now are like this: the Local Server, which kiosks report their data to gets updated from the kiosks, but the remote server does not. Or, vis versa when the user registers on a kiosk, the remote server updates but the local server does not. But yeah, without much more detail, I imagine a lot of this info isn't helpful. I've bought a book "How Google Tests Software", but it's really a book more about 'how their software testing is different from Microsoft'. It doesn't teach how to test so much as why their methods are better. Does anyone have a good book that I can buy? An ebook maybe? My local Barnes and Noble kinda had a terrible selection. I also figure a book from 2005 is not necessarily that good either.

• Oracle @Munich Business School

  - by Maria Sandu

  Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Last Wednesday, Lisa from the Graduate Recruitment team and her colleague Philipp from Sales visited the Munich Business School to talk about IT challenges, Sales and Career Opportunities at Oracle. Although the talk started at 6:30 pm, the audience of about 100 students was still attentive and curious. First they were provided with some facts about Oracle, then Philipp went into detail and took them through current IT challenges like ‘Social’, ‘Mobile’, ‘Information’ and ‘Cloud’ and how Oracle solutions can help facing these challenges. He also demonstrated what kind of prerequisites and qualifications are required to become a successful Sales person. When talking about his own career, the audience got even more anxious to hear what he would tell them. Finally, students asked questions on career opportunities across Europe or on other topics they were interested in.

• Sony Ericsson Windows driver problem

  - by alex

  I've installed Update Service and MediaGo for my Sony Ericsson phone but one of the drivers that was installed along with the software is causing problems in Windows 7 x64. Looking in the Event Log I see the following warning: Detected unrecognized USB driver (\Driver\seehcri) This is the driver corresponding to the Sony Ericsson seehcri Control Device. The failure to recognize the USB driver is causing problems with other services, namely the VMware USB Arbitration Service. It should normally start automatically but, due to the failure to recognize the seehcri USB driver, it fails with the following error: Error 31: A device attached to the system is not functioning. Disabling the driver has not helped at all. The VMWare service still refuses to start and I keep getting both warnings in the Event Log. I would like to remove the Sony Ericsson driver but unfortunately, that's not possible. Uninstalling the Sony Ericsson seehcri Control Device from Device Manager causes Windows to almost completely freeze up while trying to look for drivers for unrecognized hardware. Windows tries over and over again to locate and install drivers for an Unknown device, failing every time. Looking in Device Manager, it simply fills up with hundreds of unknown devices, also using up the CPU to almost 85% in the process. What should I do? How can I safely remove the driver without causing Windows to look for a new driver?

• Hyper-V Server 2012 - "No Active Network Adapter Found"

  - by Vazgen

  I just installed Hyper-V Server 2012 and first thing I get when logging in to the host is "No Active Network Adapter Found". I know I have to use the following command: pnputil –i –a <inf file> I found the Realtek Network Driver for my MB for Windows 7 here: http://za.asus.com/Motherboards/AMD_AM3Plus/M5A97_PRO/#download But there is not one for Windows 8 so I tried using the Win 7 one with PnPUtil, and I got: Failed to install the driver on any of the devices on the system: No more data is available. Does this really mean I can't use Hyper-V Server 2012 with my motherboard? This is hard to believe because I installed Windows Server 2012 directly (prior to installing Hyper-V Server 2012) on this same computer and I had internet access on that server without even configuring any drivers. Ok so I went to PowerShell from cmd and typed Get-NetIPConfiguration And it said the name of my driver (Realtek) and "Disconnected". I switched the Ethernet wire from my primary computer with my server and everything was fixed. Interestingly, my primary computer connects to the internet just fine with the wire that was previously in the server, just with much slower speed. Does anyone know what could be the difference between these 2 Ethernet wires?

• Watchguard SSLVPN user connection issue

  - by Tory Newnham

  I have a user that needs access to our SSLVPN on our Watchguard firewall from his company issued laptop. The problem is when he tries to connect as himself he cannot connect. If I login to the machine it works fine, if I add him to the domain admins group in Active Directory it works fine… So, we know it is an access issue but I cannot figure out what access he needs. He is in the SSLVPN-Users group which I thought would give them all the access they needed but apparently not… Here is the output of the SSLVPN Logs when trying to connect: 2012-09-14T15:40:55.834 Launching WatchGuard Mobile VPN with SSL client.

• Windows CE 6.0 time setting in registry being overrided

  - by JaminSince83

  I have asked this question on stack overflow but its probably better suited here. So I have a Motorola MC3190 Mobile Barcode scanning device with Windows CE 6.0. Now I want to get the device to sync its date/time on boot up with our domain controller using a registry file that I have created. I have used this registry file below to get close to what I require. REG 1 REGEDIT4 [HKEY_LOCAL_MACHINE\Services\TIMESVC] "UserProcGroup"=dword:00000002 "Flags"=dword:00000010 "multicastperiod"=dword:36EE80 "threshold"=dword:5265C00 "recoveryrefresh"=dword:36EE80 "refresh"=dword:5265C00 "Context"=dword:0 "Autoupdate" = dword:1 "server" = "NAMEOFMYSERVER" "ServerRole" = dword:0 "Trustlocalclock" = dword:0 "Dll"="timesvc.dll" "Keep"=dword:1 "Prefix"="NTP" "Index"=dword:0 [HKEY_LOCAL_MACHINE\nls] "DefaultLCID" = dword:00000809 [HKEY_LOCAL_MACHINE\nls\overrides] "LCID" = dword:00000809 [HKEY_LOCAL_MACHINE\Time] @ = "UTC" "TimeZoneInformation"=hex:\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00 [HKEY_LOCAL_MACHINE\Time Zones] @ = "UTC" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Clock] "AutoDST" = dword:00000000 Now it gets the correct date and shows the time zone correctly however the time is always 5 hours behind on Eastern Standard Time, which is really annoying. I have researched heavily into this and this question has been asked before here As you will see I have copied what it suggests but it doesnt work. Something is overiding the time which I dont understand enough about to resolve. I cannot find any other setting to get it to set the time correctly. Any help would be greatly appreciated.
