• Most effective work habit for coding? [on hold]

  - by Cris

  Working on a big solo project (~15,000 LOC), I am encountering the following phenomenon: I seem to work best when I program in short bursts of 10-15 minutes. Right now I am working on a section which is a complete first time for me architecturally and if I have any architectural issues that emerge when doing the implementation, I seem to be able to best serve these by taking a total break. Then, later, sketching out the ideas on some paper. And when I feel I have sufficient clarity, then going back to code. This iterates until that architectural issue for that section is resolved. This seems quite counter intuitive: that I can progress more quickly by coding less, and taking more breaks. I am nearing the end of the sections which are "first times" for me, and about to dive into stuff which I am much more familiar and am wondering if this counter intuitive efficiency will continue. So my question is: even for regular coding of sections one is familiar with, which don't require constant re-clarification of the best architecture, is more progress to be attained by taking more breaks and coding in bursts?

• New CAM Editor v2.3 with Open-XDX for Open Data APIs

  - by drrwebber

  Creating actual working XML exchanges, loading data from data stores, generating XML, testing, integrating with web services and then deployment delivery takes a lot of coding and effort. Then writing the documentation, models, schema and doing naming and design rule (NDR) checks and packaging all this together (such as for NIEM IEPD use). What if there was a tool that helped you do all that easily and simply? Welcome to the new Open-XDX and the CAM Editor! Open-XDX uses code-free techniques in combination with CAM templates and visual drag and drop to rapidly design your XML exchange. Then Open-XDX will automatically generate all the SQL for you, read the database data, generate and populate the valid output XML, and filter with parameters. To complete the processing solution Open-XDX works with web services and JDBC database connections as a callable module that can be deployed plug and play with your middleware stack, all with just a few lines of Java code (about 5 actually). You can build either Query/Response or Publish/Subscribe services from existing data stores to XML literally in minutes. To see a demonstration of using Open-XDX, a MySQL data store and integrating with Oracle Web Logic server please see this short few minutes video - http://youtube.com/user/TheCameditor There is also a Quick Guide available that provides more technical insights along with a sample pack download of templates and SQL that you can try for yourself. Head on over to our project resource site to learn more, download the latest CAM Editor and see links to all the resources and materials. We look forward to seeing how the developer community is able to jump start information sharing initiatives using this new innovative approach.

• Software licensing template that gives room for restricting usage to certain industries/uses of software/source

  - by BSara

  *Why this question is not a duplicate of the questions specified as such: I did not ask if there was a license that restricted specific uses and I did not ask if I could rewrite every line of any open source project. I asked very specifically: "Does there exist X? If not, can I Y with Z?". As far as I can tell, the two questions that were specified as duplicates do not answer my specific question. Please remove the duplicate status placed on the question. I'm developing some software that I would like to be "semi" open source. I would like to allow for anyone to use my software/source unless they are using the software/source for certain purposes. For example, I don't want to allow usage of the software/source if it is being used to create, distribute, view or otherwise support pornography, illegal purposes, etc. I'm no lawyer and couldn't ever hope to write a license myself nor do I have to time to figure how to best do this. My question is this: Does there exist a freely available license or a template for a license that I can use to license my software under they conditions explained above just like one can use the Creative Commons licenses? If not, am I allowed to just alter one of Creative Commons licenses to meet my needs?

• Android Card Game Database for Deck Building

  - by Singularity222

  I am making a card game for Android where a player can choose from a selection of cards to build a deck that would contain around 60 cards. Currently, I have the entire database of cards created that the user can browse. The next step is allowing the user to select cards and create a deck with whatever cards they would like. I have a form where the user can search for specific cards based off a few different attributes. The search results are displayed in a List Activity. My thought about deck creation is to add the primary key of each card the user selects to a SQLite Database table with the amount they would like in the deck. This way as the user performs searches for cards they can see the state of the deck. Once the user decides to save the deck. I'll export the card list to XML and wipe the contents of the table. If the user wanted to make changes to the deck, they would load it, it would be parsed back into the table so they could make the changes. A similar situation would occur when the eventually load the deck to play a game. I'm just curious what the rest of you may think of this method. Currently, this is a personal project and I am the only one working on it. If I can figure out the best implementation before I even begin coding I'm hoping to save myself some time and trouble.

• What is causing these visual artifacts on my OpenGL sprites?

  - by Amplify91

  What could be the cause of the defects in my characters sprite? I am using OpenGL ES 2.0. I draw my sprites in a sprite batch that uses UV coordinates from one large texture atlas. If you look around the character' edges, you'll see two noticeable problems: The invisible alpha background is not invisible, but shows a strange static-like background. There are unwanted streaks where the character nears the edge of the frame (but only in some frames of the animation, this happened to be one of them). Any idea what could be causing these? I will provide related code if asked for, but I'll try to avoid just dumping the entire project and expecting someone to look through it all. EDIT: Here's a bit of code: This is how I generate my UV coordinates: private float[] createFrameUV(int frameWidth, int frameHeight, int x, int y){ float[] uv = new float[4]; if(numberOfFrames>1){ float width = (float)frameWidth / (float)mBitmap.getWidth(); float height = (float)frameHeight / (float)mBitmap.getHeight(); float u = (float)x / (float)mBitmap.getWidth(); float v = (float)y / (float)mBitmap.getHeight(); uv[0] = u; uv[1] = v; uv[2] = u + width; uv[3] = v + height; }else{ uv[0] = 0f; uv[1] = 0f; uv[2] = 1f; uv[3] = 1f; } return uv; } These are some OpenGL settings: GLES20.glTexParameterf(GLES20.GL_TEXTURE_2D, GLES20.GL_TEXTURE_MIN_FILTER, GLES20.GL_LINEAR); GLES20.glTexParameterf(GLES20.GL_TEXTURE_2D, GLES20.GL_TEXTURE_MAG_FILTER, GLES20.GL_LINEAR); GLES20.glTexParameterf(GLES20.GL_TEXTURE_2D, GLES20.GL_TEXTURE_WRAP_S, GLES20.GL_CLAMP_TO_EDGE); GLES20.glTexParameterf(GLES20.GL_TEXTURE_2D, GLES20.GL_TEXTURE_WRAP_T, GLES20.GL_CLAMP_TO_EDGE);

• Is there an excuse for short variable names?

  - by KChaloux

  This has become a large frustration with the codebase I'm currently working in; many of our variable names are short and undescriptive. I'm the only developer left on the project, and there isn't documentation as to what most of them do, so I have to spend extra time tracking down what they represent. For example, I was reading over some code that updates the definition of an optical surface. The variables set at the start were as follows: double dR, dCV, dK, dDin, dDout, dRin, dRout dR = Convert.ToDouble(_tblAsphere.Rows[0].ItemArray.GetValue(1)); dCV = convert.ToDouble(_tblAsphere.Rows[1].ItemArray.GetValue(1)); ... and so on Maybe it's just me, but it told me essentially nothing about what they represented, which made understanding the code further down difficult. All I knew was that it was a variable parsed out specific row from a specific table, somewhere. After some searching, I found out what they meant: dR = radius dCV = curvature dK = conic constant dDin = inner aperture dDout = outer aperture dRin = inner radius dRout = outer radius I renamed them to essentially what I have up there. It lengthens some lines, but I feel like that's a fair trade off. This kind of naming scheme is used throughout a lot of the code however. I'm not sure if it's an artifact from developers who learned by working with older systems, or if there's a deeper reason behind it. Is there a good reason to name variables this way, or am I justified in updating them to more descriptive names as I come across them?

• Strange and erratic transformations when using OpenGL VBOs to render scene

  - by janoside

  I have an existing iOS game with fairly simple scenes (all textured quads) and I'm using Apple's "Texture2D" class. I'm trying to convert this class to use VBOs since the vertices of my objects basically never change so I may as well not re-create them for every object every frame. I have the scene rendering using VBOs but the sizes and orientations of all rendered objects are strange and erratic - though locations seem generally correct. I've been toying with this code for a few days now, and I've found something odd: if I re-create all of my VBOs each frame, everything looks correct, even though I'm almost certain my vertices are not changing. Other notes I'm basing my work on this tutorial, and therefore am also using "IBOs" I create my buffers before rendering begins My buffers include vertex and texture data I'm using OpenGL ES 1.1 Fearing some strange effect of the current matrix GL state at the time of buffer creation I've also tried wrapping my buffer-setup code in a "pushMatrix-loadIdentity-popMatrix" block which (as expected) had no effect I'm aware that various articles have been published demonstrating that VBOs may not help performance, but I want to understand this problem and at least have the option to use them. I realize this is a shot in the dark, but has anyone else experienced this type of strange behavior? What might I be doing to result in this behavior? It's rather difficult for me to isolate the problem since I'm working in an existing, moderately complex project, so suggestions about how to approach the problem are also quite welcome.

• Access - Force Form Refresh on New Record

  - by gamerzfuse

  Let me set the stage here a bit: I have an Access project with various buttons, triggers, macros, etc. I needed an Appointment Date field to only show when the button APPOINTMENT MADE is toggled ON. This works great. The problem arises when you submit a form with the APPOINTMENT MADE toggled. Once the record is inserted, the Access file clears all fields, but leaves the Appointment Date enabled, when it should be disabled by default. I have tried the Current, Load, Before Insert, After Insert and many other options on the FORM properties. Am I missing a simple way to force a refresh so the field goes back to it's default DISABLED? Thanks in advance!

• Is there a better way to consume an ASP.NET Web API call in an MVC controller?

  - by davidisawesome

  In a new project I am creating for my work I am creating a fairly large ASP.NET Web API. The api will be in a separate visual studio solution that also contains all of my business logic and database interactions, Model classes as well. In the test application I am creating (which is asp.net mvc4), I want to be able to hit an api url I defined from the control and cast the return JSON to a Model class. The reason behind this is that I want to take advantage of strongly typing my views to a Model. This is all still in a proof of concept stage, so I have not done any performance testing on it, but I am curious if what I am doing is a good practice, or if I am crazy for even going down this route. Here is the code on the client controller: public class HomeController : Controller { protected string dashboardUrlBase = "http://localhost/webapi/api/StudentDashboard/"; public ActionResult Index() //This view is strongly typed against User { //testing against Joe Bob string adSAMName = "jBob"; WebClient client = new WebClient(); string url = dashboardUrlBase + "GetUserRecord?userName=" + adSAMName; //'User' is a Model class that I have defined. User result = JsonConvert.DeserializeObject<User>(client.DownloadString(url)); return View(result); } . . . } If I choose to go this route another thing to note is I am loading several partial views in this page (as I will also do in subsequent pages). The partial views are loaded via an $.ajax call that hits this controller and does basically the same thing as the code above: Instantiate a new WebClient Define the Url to hit Deserialize the result and cast it to a Model Class. So it is possible (and likely) I could be performing the same actions 4-5 times for a single page. Is there a better method to do this that will: Let me keep strongly typed views. Do my work on the server rather than on the client (this is just a preference since I can write C# faster than I can write javascript).

  I renamed some of my virtual machine files and never did a backup before doing so. Now I can't get the machine to start again as it asks for the old files. I have updated references to these files in the project setting files which are in plain text. The virtual machine keeps on asking for the files anyway. I never shut off the machine properly before starting to rename the files. How can I save my work done on the virtual machine disk? I have tried to create a new machine and adding the disk from the old virtual machine only but there seems to be dependencies between disk files. The parent drive cannot be found I am told when trying to add the drive of interest. Any suggestion on how to resolve the issue?

• Dirt Cheap Bi-Directional Antenna Wirelessly Extends Your LAN

  - by Jason Fitzpatrick

  If you’re looking for an effective way to link remote LANs without the hassle of laying cable, this DIY bi-directional antenna is a quick (and cheap) method for bringing internet access to outbuildings and other locations. Tinker Danilo Larizza needed to share internet access between apartments that are relatively close together but not hardwired–ruling out simply sharing the access via existing LAN infrastructure. His solution combines a simple scrap wire antenna array mounted inside a plastic food bin (seen here with the cover removed to show the antenna) and some coaxial cable to link the antenna to two routers. Our favorite part about his build is that he constructed the pair to establish if the antenna setup would even work in his location and intended to buy commercial antennas if it did; his Tupperware models worked so well, however, they’re now the permanent solution.

• Is there ever a reason to do all an object's work in a constructor?

  - by Kane

  Let me preface this by saying this is not my code nor my coworkers' code. Years ago when our company was smaller, we had some projects we needed done that we did not have the capacity for, so they were outsourced. Now, I have nothing against outsourcing or contractors in general, but the codebase they produced is a mass of WTFs. That being said, it does (mostly) work, so I suppose it's in the top 10% of outsourced projects I've seen. As our company has grown, we've tried to take more of our development in house. This particular project landed in my lap so I've been going over it, cleaning it up, adding tests, etc etc. There's one pattern I see repeated a lot and it seems so mindblowingly awful that I wondered if maybe there is a reason and I just don't see it. The pattern is an object with no public methods or members, just a public constructor that does all the work of the object. For example, (the code is in Java, if that matters, but I hope this to be a more general question): public class Foo { private int bar; private String baz; public Foo(File f) { execute(f); } private void execute(File f) { // FTP the file to some hardcoded location, // or parse the file and commit to the database, or whatever } } If you're wondering, this type of code is often called in the following manner: for(File f : someListOfFiles) { new Foo(f); } Now, I was taught long ago that instantiated objects in a loop is generally a bad idea, and that constructors should do a minimum of work. Looking at this code it looks like it would be better to drop the constructor and make execute a public static method. I did ask the contractor why it was done this way, and the response I got was "We can change it if you want". Which was not really helpful. Anyway, is there ever a reason to do something like this, in any programming language, or is this just another submission to the Daily WTF?

  I am working on Ubuntu 9.10 + LXDE as my current project. I am finding it difficult to install any new packages on this OS. For example, I need to install OpenCv package for qt webcam application, but every time it gives unmet dependencies error.And when i try to install dependencies it again show some more dependencies and so on and forms a circular loops. for example: sudo apt-get install libcv-dev .. .... The following packages have unmet dependencies: libcv-dev: Depends: libhighgui-dev (=1.0.0-6.2ubuntu1) but it is not going to installed. E: Broken packages Then I try to install libhighgui-dev as follow: sudo appt-get install libhighgui-dev .. ... The following packages have unmet dependencies: libhighgui-dev: Depends: libgtk2.0-dev but it is not going to installed E: Broken packages And this goes on never ending. Please suggest me something, as i have googled a lot and did not found any help. It may be , i m missing some primary packages to be installed.But how to find it? Any suggestion/help/link will be really appreciated. Thanks in Advance.

• What is the basic loadout for an open source web developer?

  - by DeveloperDon

  Thus far, I have mainly been an embedded developer, but I am interested in having the flexibility to do mobile and web development as well. I think my tools should include the following, but probably a lot more. LAMP stack. Java IDEs like Eclipse and IntelliJ. JS frameworks like Dojo, Node.JS, AngularJS, (is it better to mix or commit to one?). Cloud solutions like EC2 and Azure (again, ok to mix or better to commit to one?). Google APIs. Continuous integration server. Source control tools with Git for new work, SVN, CVS, +others for imports. FTP server. Unit test runners. Bug trackers. OOAD modeling tools or plug-ins? Graphic design tools? Hosting services. XML / JSON / other markup? Content management, SEO? I am also interested to know if there are tools where it might be better to mix, match, or support all available (maybe for source control) and others where the full focus should be on one (maybe Java vs. C# or Windows vs. Linux vs. MacOS). Perhaps some of these questions need context of whether the projects will be greenfield (just pick favorite) or maintenance (no choice, each project continues legacy, sometimes with a poor tools).

• Unity3d web player fails to load textures

  - by José Franco

  I'm having a problem with Unity3d Web Player. I have developed a project and succesfully deployed it in a web app. It works with absolutely no problem on my PC. This app is to be installed on two identical machines. I have installed them in both and it only works properly in one. The issue I have is on a computer it fails to properly load the models and textures, so the game runs but instead of the models I can only see black rectangles on a blue background. It has the same problem with all browsers and I get no errors either by the player or by JavaScript. The only difference between these computers is that one that has the problem is running on Windows 8.1 and the other one on Windows 8 only. Could this be the cause of the issue? It works fine on my computer with Windows 8.1. However both of the other computers have specs that are significantly lower than mine. I have already searched everywhere and it seems that it has to do with the individual games, however I think it may have to do with the computer itself because it runs properly in the other two. The specs on the computes I'm installing the app on are as follows: Intel Celeron 1.40 GHz, 2GB RAM, Intel HD Graphics If anybody could point me in the right direction I would be very grateful I forgot to mention, I'm running Unity Web player 4.3.5 and the version on the other two computers is 4.5.0

• Announcing Spacewalk Support for Oracle Linux Basic and Premier Customers

  - by Michele Casey

  Over the years, customers migrating to Oracle Linux have asked for options to provide a transitional solution for their existing system management tools (such as Red Hat Satellite Server) while evaluating and planning migrations to Oracle's Enterprise Manager, which is offered at no additional charge with Oracle Linux Support Subscriptions.  Based on this request, we are pleased to announce support for the open-source community project, Spacewalk, which is the basis for both Red Hat Satellite Server and SUSE Manager.  Effective today, customers with Oracle Linux Basic and Premier Support subscriptions have access to a fully supported Spacewalk build which can be setup to easily manage Oracle Linux systems.   Spacewalk support for Oracle Linux requires Oracle Linux 6, x86_64 for the server and provides support for Oracle Linux 5 and Oracle Linux 6 (x86, x86_64) clients.  This solution requires Oracle Database 11g Release 2 as the  supported database repository for Spacewalk with Oracle Linux.  Within the next several weeks, a limited use license for the Oracle Database will be included with this offer.  Until this is complete, customers may use an existing Oracle database license or they may begin by downloading a 30-day trial license from eDelivery.  Customers with Oracle Linux Basic and Premier subscriptions will automatically have access to the channel hosting the supported build.  Please review the release notes for further instructions. Oracle Enterprise Manager is still the recommended enterprise solution for managing Oracle Linux systems and we want to provide the easiest transition path for our customers.  We are excited to offer this solution to our Oracle Linux customers while they plan and implement their migration to Oracle Enterprise Manager.

• Distributed, Parallel, Fault-tolerant File System

  - by Eddified

  There are so many choices that it's hard to know where to start. My requirements are these: Runs on Linux Most of the files will be between 5-9 MB in size. There will also be a significant number of small-ish jpgs (100px x 100px). All of the files need to be available over http. Redundancy -- ideally it would provide the space efficiency similar to RAID 5 of 75% (in RAID 5 this would be calculated thus: with 4 identical disks, 25% of the space is used for parity = 75% efficent) Must support several petabytes of data scalable runs on commodity hardware In addition, I look for these qualities, though they are not "requirements": Stable, mature file system Lots of momentum and support etc I would like some input as to which file system works best for the given requirements. Some people at my organization are leaning towards MogileFS, but I'm not convinced of the stability and momentum of that project. GlusterFS and Lustre, based on my limited research, appear to be better supported... Thoughts?

• basic device that can connect to internet

  - by Hellnar

  Hello, I am looking for a cheap solution to my problem: I need to find either an already existing common device (that is used in restaurants, bars clubs) or a cheap new device that I will distribute to those places, which can connect to internet (via the already existing ethernet or wireless based internet) and do HTTP request/receive response and retrieve information ? (For instance can a POS device connect to internet?) For a project, I need to do identity validation on several restaurants and bars and not all of them have computers. So I will be giving "cheap and easy to use devices" and non-IT personal can use it to do http request to my server and get response. All I can think of is Cell phones and SMS.

• Was API hooking done as needed for Stuxnet to work? I don't think so

  - by The Kaykay

  Caveat: I am a political science student and I have tried my level best to understand the technicalities; if I still sound naive please overlook that. In the Symantec report on Stuxnet, the authors say that once the worm infects the 32-bit Windows computer which has a WINCC setup on it, Stuxnet does many things and that it specifically hooks the function CreateFileA(). This function is the route which the worm uses to actually infect the .s7p project files that are used to program the PLCs. ie when the PLC programmer opens a file with .s7p the control transfers to the hooked function CreateFileA_hook() instead of CreateFileA(). Once Stuxnet gains the control it covertly inserts code blocks into the PLC without the programmers knowledge and hides it from his view. However, it should be noted that there is also one more function called CreateFileW() which does the same task as CreateFileA() but both work on different character sets. CreateFileA works with ASCII character set and CreateFileW works with wide characters or Unicode character set. Farsi (the language of the Iranians) is a language that needs unicode character set and not ASCII Characters. I'm assuming that the developers of any famous commercial software (for ex. WinCC) that will be sold in many countries will take 'Localization' and/or 'Internationalization' into consideration while it is being developed in order to make the product fail-safe ie. the software developers would use UNICODE while compiling their code and not just 'ASCII'. Thus, I think that CreateFileW() would have been invoked on a WINCC system in Iran instead of CreateFileA(). Do you agree? My question is: If Stuxnet has hooked only the function CreateFileA() then based on the above assumption there is a significant chance that it did not work at all? I think my doubt will get clarified if: my assumption is proved wrong, or the Symantec report is proved incorrect. Please help me clarify this doubt. Note: I had posted this question on the general stackexchange website and did not get appropriate responses that I was looking for so I'm posting it here.

• HTML5 video capture and streaming?

  - by Shyatic

  I'm working on kind of an educational site, where there are teachers and students around the world (potentially). Since it's a non-profit site, and I don't have the need for it to be done tomorrow (kind of a side project of something bigger), I wanted to know the best way to figure out how to do this. I'm not a programmer by trade, I've been on the systems side of things for years, but I understand most technology and the question here is more how to gauge what to do so I can get the right resources in place. That said... here's what I am looking at. I figure the future is HTML5, and that's probably where I'd rather spend my efforts given that it will be cross platform and without the need for plugins. It will work on mobile as well. Question is, how well does HTML5 handle input media, say desktop capture and camera, or on mobile perhaps, where I'd want to use the user's phone camera, etc. Second question is dynamic streaming... I've read about MPEG DASH, then there are technologies like Smooth Streaming (which I think given the way Silverlight is going is going to be gone or useless), then also Apple and Flash, but if I'm doing HTML5 it doesn't benefit me. Any ideas here would be really helpful, and the more detail the better! :) That's about it... there are free chat services out there like using the MSN Web Chat controls (how good they are, I don't know, but worldwide most people have a Hotmail/MSN account) so I can use that for chat. I don't know its limitations of course, but that's something if people know or have suggestions, then I'm all ears. Thanks for the help, I greatly appreciate it!

• Expanding existing DVCS Wiki

  - by A Lion

  A portion of my job is to maintain technical documentation for a rapidly expanding manufacturing company. Because it is only a portion of my job and the company's product line is expanding so quickly, I can't stay on top of the documentation. As a result, I've been yearning for an information management system with a handful of specific features. I've found many products that have a subset, but none that have all the features I'm looking for. I'm at the point of picking an existing product and expanding it to cover my desired feature set, however, this will be a pet project and I will be learning the underlying language as I go. So, the main question is which existing product will be the easiest to expand to cover the full feature set and has a relatively easy to learn language? Alternatively, have I missed another existing program that will cover the feature set or should be in my list of "close, but not quite there"? Feature Set web interface based on a distributed version control system (e.g., git) easy to edit by logged in novices (e.g. wiki, multimarkdown) outputs in more traditional formats (e.g., doc, odt, pdf) edits held in queue until editor/engineer/manager approves them (e.g., MS Word editing) [this is the really big elephant in list - suggestions on where to start appreciated] edits held in queue specifically for engineer approval [extra limb of the elephant in the list] well-supported in the open source community Closest, but not quite there ikiwiki - http://ikiwiki.info (php) lots of awesome functionality and extensions, including easy to edit and based on DVCS lacks a review/forward for review queue appears to be well-supported within the OSS community gitit - http://gitit.net/ (haskell) easy to edit and based on DVCS lots of outputs in traditional formats a great web-based gui diff interface lacks a review/forward for review queue appears to be primarily maintained by one individual
