• Compiling NETGEAR WNR2000v3 firmware under 12.04.1 LTS

  - by Madmanguruman

  I'm trying to compile the GPL NETGEAR firmware for the WNR2000v3 router using Ubuntu 12.04.1 LTS. I've downloaded and extracted the source, installed everything I think I need, yet there are two build dependencies that I cannot resolve: > make menuconfig .... Build dependency: Please install ncurses. (Missing libncurses.so or ncurses.h) Build dependency: Please install zlib. (Missing libz.so or zlib.h) I've tried apt-getting all of the following packages: libncurses5 libncurses5:i386 libncurses5-dev zlib1g zlib1g-dev zlib1g-dbg The missing libs seem 'real': the target .so files aren't in /usr/lib, although the .h files are in /usr/include. EDIT: some Googling told me of broken or missing symlinks. I found the following: /lib/i386-linux-gnu/libncurses.so.5 -> libncurses.so.5.9 /lib/i386-linux-gnu/libncurses.so.5.9 /lib/i386-linux-gnu/libncursesw.so.5 -> libncursesw.so.5.9 /lib/i386-linux-gnu/libncursesw.so.5.9 /lib/i386-linux-gnu/libz.so.1 -> libz.so.1.2.3.4 /lib/i386-linux-gnu/libz.so.1.2.3.4 so I tried to symlink these to /usr/lib: /usr/lib/libncurses.so -> /lib/i386-linux-gnu/libncurses.so.5 /usr/lib/libz.so -> /lib/i386-linux-gnu/libz.so.1 but the project still complains about missing libncurses and zlib. EDIT: I was able to get the dependencies to work under 8.04. Need to cross-reference things now. Does anyone have some tips on how to debug this sort of issue?

• Dealing With Table Borders In OOXML

  - by Tim Murphy

  Note: Cross posted from Coding The Document. Permalink Formatting tables in a document programmatically can be a very complex task.  This is the major reason which we start our document generation projects with templates instead of building components in a document by hand. Borders are on aspect of a table that you may want to fomat.  Borders are used to make certain content in a table stand out.  If you need to conditionally set and remove borders there is something that you need to be aware of.  Even in OOXML you have the concepts of styles, inheriting styles and overriding styles. When Word defines a table it will reference a global style such as “TableGrid”.  This style will include the borders for the table.  Specifically the InsideHorizontalBorder and InsideVerticalBorder define the borders for the cells.  These can be overridden by the TableCellBorders collection of a particular cell.  Adding a double right border on a cell is as easy as the couple of lines of code below. wordprocessing.TableCellBorders borders = new wordprocessing.TableCellBorders(); borders.RightBorder = new RightBorder(){Val = BorderValues.Double, Color = "000000", ThemeColor = ThemeColorValues.Text1, Size = (UInt32Value)4U, Space = (UInt32Value)0U }; cell.TableCellProperties.Append(borders); If I want to revert back to the table’s style for cell borders I simply need to remove all children from the TableCellBorders collection.  It is like removing a class identifier from a TD tag in HTML.  The style in the parent object takes back over. With the knowledge of how the borders work you can take the concept and apply it to other effects of styles. del.icio.us Tags: OOXML,Office Open XML,Microsoft Office 2007,Microsoft Word 2007,table,style,border

• CERN Announces the Discovery of a Higgs-Boson-like Particle

  - by Jason Fitzpatrick

  CERN scientists dropped a press release today indicating they’ve found a particle consistent with the long sought after Higgs Boson particle–the “God” particle, that could help radically refine our understanding of Standard Model of Particle Physics. For years scientists at CERN have been harnessing the power of the Large Hadron Collider to answer fundamental questions about the nature of particles and the universe around us. In the above video John Ellis, a theoretical physicist, answers the question “What is the Higgs Boson?” The video pairs nicely with the CERN press release: “We observe in our data clear signs of a new particle, at the level of 5 sigma, in the mass region around 126 GeV. The outstanding performance of the LHC and ATLAS and the huge efforts of many people have brought us to this exciting stage,” said ATLAS experiment spokesperson Fabiola Gianotti, “but a little more time is needed to prepare these results for publication.” “The results are preliminary but the 5 sigma signal at around 125 GeV we’re seeing is dramatic. This is indeed a new particle. We know it must be a boson and it’s the heaviest boson ever found,” said CMS experiment spokesperson Joe Incandela. “The implications are very significant and it is precisely for this reason that we must be extremely diligent in all of our studies and cross-checks.” “It’s hard not to get excited by these results,” said CERN Research Director Sergio Bertolucci. “ We stated last year that in 2012 we would either find a new Higgs-like particle or exclude the existence of the Standard Model Higgs. With all the necessary caution, it looks to me that we are at a branching point: the observation of this new particle indicates the path for the future towards a more detailed understanding of what we’re seeing in the data.” How to Use an Xbox 360 Controller On Your Windows PC Download the Official How-To Geek Trivia App for Windows 8 How to Banish Duplicate Photos with VisiPic

• First time application where to start?

  - by Nazariy

  After many years of searches and copy pasting, I'm still looking for simple solution that can transliterate text input on the fly from one key set to another. There are quite few online services that provide this feature but it still quite annoying to go online all the time. Unfortunately there is not that many applications left which are capable of doing so, and none of them supported by this day. I decided to make my own and at same time to learn something new for my self. The idea is quite simple: application should sit in system tray and wait until input language get changed, for example to Russian. If Russian language is activated, application should start to listen for user key strokes combination and replace them based on custom dictionary for example R = ?, SH = ? etc. I should be able to bind application to any installed language (Russian, Ukrainian, Bulgarian, Belarusian etc.) and customise dictionary for any of them. So my question is: Which language should I chose for this task C++, C# or might be something hardcore like Assembler, as application should work natively with Windows XP/Vista/7 or possibly Mac. (cross platform support is good but my main target is Windows) Due to nature of application behaviour how can I tell anti-virus software that it is not a "Key Logger" and basically not a virus? Where should I start and what should I be aware of? P.S. My current programming knowledge is quite basic, PHP and JavaScript with Object Oriented approach.

• WebGL CORS error loading simple texture in Chrome

  - by mathacka

  Here's my code: function loadTexture() { textureImage = new Image(); textureImage.onload = function() { setupTexture(); } textureImage.src = "jumper2.png"; } function setupTexture() { texture = gl.createTexture(); gl.bindTexture(gl.TEXTURE_2D, texture); gl.pixelStorei(gl.UNPACK_FLIP_Y_WEBGL, true); // this next line has the error: Uncaught SecurityError: An attempt was made to break through the security policy of the user agent. gl.texImage2D(gl.TEXTURE_2D, 0, gl.RGBA, gl.RGBA, gl.UNSIGNED_BYTE, textureImage); gl.texParameteri(gl.TEXTURE_2D, gl.OES_TEXTURE_FLOAT_LINEAR, gl.NEAREST); if (!gl.isTexture(texture)) { alert("Error: Texture is invalid"); } glProgram.samplerUniform = gl.getUniformLocation(glProgram, "uSampler"); gl.uniform1i(glProgram.samplerUniform, 0); } I've researched it and it is a CORS error a "Cross-origin resource sharing" error, but it's a local file! I can't figure out what's wrong. I did make the picture using gimp, and I'm not sure the coding was right on the export, but I eliminated a previous error using "gl.OES_TEXTURE_FLOAT_LINEAR".

• Best way to convert existing project to be open source in GitHub

  - by Tom

  I've been working on a personal closed source project for some time and would like to make it open source. I've never created my own open source project before so it will be a good learning experience. I have been using GitHub as source control, so once I've written some decent docs on how to use and develop for it etc, it should be as simple as switching the repo to be public right? I guess my main question is around licencing. I was thinking of going with Apache 2.0 licence just because it seems to be widely used. It requires the licence header to be attached to all the source files, but if I do that now then all the other commits in the past will have it missing. Does that mean some one could pull an earlier version and it wouldn't have a licence? Is it best to start a new repo with the initial commit containing all the code with licence headers? Or maybe is there some advanced Git functionality that allows me to apply the licence header to all existing commits some how? Cheers.

• Quaternion Camera

  - by Alex_Hyzer_Kenoyer

  Can someone help me figure out how to use a Quaternion with the PerspectiveCamera in libGDX or in general? I am trying to rotate my camera around a sphere that is being drawn at (0,0,0). I am not sure how to go about setting up the quaternion correctly, manipulating it, and then applying it to the camera. Edit: Here is what I have tried to do so far. // This is how I set it up Quaternion orientation = new Quaternion(); orientation.setFromAxis(Vector3.Y, 45); // This is how I am trying to update the rotations public void rotateX(float amount) { Quaternion temp = new Quaternion(); temp.set(Vector3.X, amount); orientation.mul(temp); } public void rotateY(float amount) { Quaternion temp = new Quaternion(); temp.set(Vector3.Y, amount); orientation.mul(temp); } public void updateCamera() { // This is where I am unsure how to apply the rotations to the camera // I think I should update the view and projection matrices? camera.view.mul(orientation); ... }

• Choosing the right language for the job

  - by Ampt

  I'm currently working for a company on the engineering team of about 5-6 people and have been given the job of heading up the redesign of an embedded system tester. We've decided the general requirements and attributes that would be desirable in the system, and now I have to decide on a language to use for the system, or at the very least come up with a list of languages with pros and cons to present to the team. The general idea of the project is that we currently have a tester written in c++, which was never designed to be a tester, but instead has evolved to be such over the course of 3-4 years due to need. Writing tests for a new product requires modifying the 'framework' and writing code that is completely non-human readable or intuitive due to the way the system was originally designed. Now, we've decided that the time to modify this tester for each new product that we want to test has become too high and want to partially re-write the system so that we can program the actual tests in a scripting language that would then use the modified c++ framework on the back end to test the actual systems. The c++ framework would be responsible for doing all the actual work and the scripting language would just integrate with that to tell the framework what to do. Never having programmed in a scripting language (we program embedded systems), I've run into a wall where I have no experience with any of the languages that we could possibly use, but must somehow give pros and cons of each language so that we can choose the best one for the job. Currently my short list of possibilities includes: Python TCL Lua Perl My question is this: How can a person evaluate a language that he/she has never used before? What criteria are good indicators for a languages potential usability on a project? While helpful suggestions for my particular case are appreciated, I feel that this is a good skill to possess and would like to be able to apply this to many different projects if at all possible

• Working with Legacy code #5: The blackhole.

  - by andrewstopford

  Someone creates a class or series of classes for something, the classes are big in size with large complicated methods. The effort is a sea of technical debt for the entire team but in the thick of the daily chaos it is lost. With out the coder talking to the team, with no team code policy and no code reviews (and action points) it remains. Pretty soon the team forget about that code. A few weeks\months\years goes by, some of the team may have left, some may remain but business asks for the team to add to that code. The team is now looking at a black hole, no one knows how it works, what it does, what it is for, it is a smelly hell hole and the deadline is fast approaching. The team now tries to change the code, with no approach at unit tests or refactoring in fear of breaking the black hole the team do just that and the business have just lost money. If you are faced with a black hole you need to look back over my series, even a black hole in what might seem like a clean unit tested application. Don't be fooled into thinking that legacy code does not apply to your code base.  The next stage is don't let blackholes in your codebase. Effective code reviews, team communication and good overal team coding policies will really help. Even if you are faced with a deadline do not let them appear, stop, take stock, what can be done and who can help. If you allow them through they will grow and grow and grow and the technical debt will hit you like a tidal wave soon enough,.

• Clean Code Developer & Certification in IT - MSCC 21.09.2013

  It was a very busy weekend this time, and quite some hectic to organise the second meetup on a Saturday for the Mauritius Software Craftsmanship Community (MSCC) but it was absolutely fun. Following, I'm writing a brief summary about the topics we spoke about and the new impulses I got. "What a meetup... I was positively impressed. At the beginning I thought that noone would actually show up but then by the time the room got filled. Lots of conversation, great dialogues and fantastic networking between fresh students, experienced students, experienced employees, and self-employed attendees. That's what community is all about!" Above quote was my first reaction shortly after the gathering. And despite being busy during the weekend and yesterday, I took my time to reflect a little bit on things happened and statements made before writing it here on my blog. Additionally, I was also very curious about possible reactions and blogs from other attendees. Reactions from other craftsmen Let me quickly give you some links and quotes from others first... "Like Jochen posted on facebook, that was indeed a 5+ hours marathon (maybe 4 hours for me but still) … Wohoo! We’re indeed a bunch of crazy geeks who did not realise how time flew as we dived into the myriad discussions that sprouted. Yet in the end everyone was happy (:" -- Ish on MSCC meetup - The marathon (: "And the 4hours spent @ Talking drums bore its fruit..I was doing something I never did before....reading the borrowed book while walking....and though I was not that familiar with things mentionned in the book...I was skimming,scanning & flipping...reading titles...short paragraphs...and I skipped pages till I reached home." -- Yannick on Mauritius Software Craftsmanship 1st Meet-up "Hi Developers, Just wanted to share with you the meetups i attended last Saturday - [...] - The second meetup is the one hosted by Jochen Kirstätter, the MSCC, where the attendees were Craftsman, no woman, this time - all sharing the same passion of being a developer - even though it is on different platforms(Windows - Windows Phone - Linux - Adobe(yes a designer) - .Net) - but we manage to sit at the same table - sharing developer views and experience in the corporate world - also talking about good practice when coding( where Jochen initiated a discussion on Clean Coding ) i could not stay till the end - but from what i have heard - the longer you stay the more fun you have till 1600. Developers in the Facebook grouping i invite you to stay tuned about the various developer communities popping up - where you can come to share and learn good practices, develop the entrepreneurial spirit, and learn and share your passion about technologies" -- Arnaud on Facebook More feedback has been posted on the event directly. So, should I really write more? Wouldn't that spoil the impressions? Starting the day with a surprise Indeed, I was very pleased to stumble over the existence of Mobile Monday Mauritius on LinkedIn, an association about any kind of mobile app development, mobile gadgets and latest smartphones on the market. Despite the Monday in their name they had scheduled their recent meeting on Saturday between 10:00 and 12:00hrs. Wow, what a coincidence! Let's grap the bull by its horns and pay them an introductory visit. As they chose the Ebene Accelerator at the Orange Tower in Ebene it was a no-brainer to leave home a bit earlier and stop by. It was quite an experience and fun to talk to the geeks over there. Really looking forward to organise something together.... Arriving at the venue As the children got a bit uneasy at the MoMo gathering and I didn't want to disturb them too much, we arrived early at Bagatelle. Well, no problems as we went for a decent breakfast at Food Lover's Market. Shortly afterwards we went to our venue location, Talking Drums, and prepared the room for the meeting. We only had to take off a repro-painting of the wall in order to have a decent area for the projector. All went very smooth and my two little ones were of great help. Just in time, our first craftsman Avinash arrived on the spot. And then the waiting started... Luckily, not too long. Bit by bit more and more IT people came to join our meeting. Meanwhile, I used the time to give a brief introduction about the MSCC in general, what we are (hm, maybe I am) trying to achieve and that the recent phase is completely focused on creating more awareness that a community like the MSCC is active here in Mauritius. As soon as we reached some 'critical mass' of about ten people I asked everyone for a short introduction and bio, just in case... Conversation between participants started to kick in and we were actually more networking than having a focus on our topics of the day. Quick updates on latest news and development around the MSCC Finally, Clean Code Developer No matter how the position is actually called, whether it is Software Engineer, Software Developer, Programmer, Architect, or Craftsman, anyone working in IT is facing almost the same obstacles. As for the process of writing software applications there are re-occurring patterns and principles combined with some common exercise and best practices on how to resolve them. Initiated by the must-read book 'Clean Code' by Robert C. Martin (aka Uncle Bob) the concept of the Clean Code Developer (CCD) was born already some years ago. CCD is much likely to traditional martial arts where you create awareness of certain principles and learn how to apply practices to improve your style. The CCD initiative recommends to indicate your level of knowledge and experience with coloured wrist bands - equivalent to the belt colours - for various reasons. Frankly speaking, I think that the biggest advantage here is provided by the obvious recognition of conceptual understanding. For example, take the situation of a team meeting... A member with a higher grade in CCD, say Green grade, sees that there are mainly Red grades to talk to, and adjusts her way of communication to their level of understanding. The choice of words might change as certain elements of CCD are not yet familiar to all team members. So instead of talking in an abstract way which only Green grades could follow the whole scenario comes down to Red grade level. Different story, better results... Similar to learning martial arts, we only covered two grades during this occasion - black and red. Most interestingly, there was quite some positive feedback and lots of questions about the principles and practices of the red grade. And we gathered real-world examples from various craftsman and discussed them. Following the Clean Code Developer Red Grade and some annotations from our meetup: CCD Red Grade - Principles Don't Repeat Yourself - DRY Keep It Simple, Stupid (and Short) - KISS Beware of Optimisations! Favour Composition over Inheritance - FCoI Interestingly most of the attendees already heard about those key words but couldn't really classify or categorize them. It's very similar to a situation in which you do not the particular for a thing and have to describe it to others... until someone tells you the actual name and suddenly all is very simple. CCD Red Grade - Practices Follow the Boy Scouts Rule Root Cause Analysis - RCA Use a Version Control System Apply Simple Refactoring Pattern Reflect Daily Introduction to the principles and practices of Clean Code Developer - here: Red Grade As for the various ToDo's we commonly agreed that the Boy Scout Rule clearly is not limited to software development or IT administration but applies to daily life in general. Same for the root cause analysis, btw. We really had good stories with surprisingly endings and conclusions. A quick check about who is using a version control system brought more drive into the conversation. Not only that we had people that aren't using any VCS at all, we also had the 'classic' approach of backup folders and naming conventions as well as the VCS 'junkie' that has to use multiple systems at a time. Just for the records: Git and GitHub seem to be in favour of some of the attendees. Regarding the daily reflection at the end of the day we came up with an easy solution: Wrap it up as a blog entry! Certifications in IT This is kind of a controversy in IT in general. Is it interesting to go for certifications or are they completely obsolete? What are the possibilities to get certified? What are the options we have in Mauritius? How would certificates stand compared to other educational tracks like Computer Science or Web Design. The ratio between craftsmen with certifications like MCP, MSTS, CCNA or LPI versus the ones without wasn't in favour for the first group but there was a high interest in the topic itself and some were really surprised to hear that exam preparations are completely free available online including temporarily voucher codes for either discounts or completely free exams. Furthermore, we discussed possible options on forming so-called study groups on a specific certificates and organising more frequent meetups in order to learn together. Taking into consideration that we have sponsored access to the video course material of Pluralsight (and now PeepCode as well as TrainSignal), we might give it a try by the end of the year. Current favourites are LPIC Level 1 and one of the Microsoft exams 40-78x. Feedback and ideas for the MSCC The closing conversations and discussions about how the MSCC is recently doing, what are the possibilities and what's (hopefully) going to happen in the future were really fertile and I made a couple of mental bullet points which I'm looking forward to tackle down together with orher craftsmen. Eventually, it might be a good option to elaborate on some issues during our weekly Code & Coffee sessions one Wednesday morning. Active discussion on various IT topics like certifications (LPI, MCP, CCNA, etc) and sharing experience Finally, we made it till the end of the planned time. Well, actually the talk was still on and we continued even after 16:00hrs. Unfortunately, we (the children and I) had to leave for evening activities. My resume of the day... It was great to have 15 craftsmen in one room. There are hundreds of IT geeks out there in Mauritius, and as Mauritius Software Craftsmanship Community we still have a lot of work to do to pass on the message to some more key players and companies. Currently, it seems that we are able to attract a good number of students in Computer Science... but we have a lot more to offer, even or especially for IT people on the job. I'm already looking forward to our next Saturday meetup in the near future. PS: Meetup pictures are courtesy of Nirvan Pagooah. Thanks for sharing...

• Sesame Data Browser: filtering, sorting, selecting and linking

  - by Fabrice Marguerie

  I have deferred the post about how Sesame is built in favor of publishing a new update.This new release offers major features such as the ability to quickly filter and sort data, select columns, and create hyperlinks to OData. Filtering, sorting, selecting In order to filter data, you just have to use the filter row, which becomes available when you click on the funnel button: You can then type some text and select an operator: The data grid will be refreshed immediately after you apply a filter. It works in the same way for sorting. Clicking on a column will immediately update the query and refresh the grid.Note that multi-column sorting is possible by using SHIFT-click: Viewing data is not enough. You can also view and copy the query string that returns that data: One more thing you can to shape data is to select which columns are displayed. Simply use the Column Chooser and you'll be done: Again, this will update the data and query string in real time: Linking to Sesame, linking to OData The other main feature of this release is the ability to create hyperlinks to Sesame. That's right, you can ask Sesame to give you a link you can display on a webpage, send in an email, or type in a chat session. You can get a link to a connection: or to a query: You'll note that you can also decide to embed Sesame in a webpage... Here are some sample links created via Sesame: Netflix movies with high ratings, sorted by release year Netflix horror movies from the 21st century Northwind discontinued products with remaining stock Netflix empty connection I'll give more examples in a post to follow. There are many more minor improvements in this release, but I'll let you find out about them by yourself :-)Please try Sesame Data Browser now and let me know what you think! PS: if you use Sesame from the desktop, please use the "Remove this application" command in the context menu of the destkop app and then "Install on desktop" again in your web browser. I'll activate automatic updates with the next release.

• Hex Dump using LINQ (in 7 lines of code)

  - by Fabrice Marguerie

  Eric White has posted an interesting LINQ query on his blog that shows how to create a Hex Dump in something like 7 lines of code.Of course, this is not production grade code, but it's another good example that demonstrates the expressiveness of LINQ.Here is the code:byte[] ba = File.ReadAllBytes("test.xml");int bytesPerLine = 16;string hexDump = ba.Select((c, i) => new { Char = c, Chunk = i / bytesPerLine })    .GroupBy(c => c.Chunk)    .Select(g => g.Select(c => String.Format("{0:X2} ", c.Char))        .Aggregate((s, i) => s + i))    .Select((s, i) => String.Format("{0:d6}: {1}", i * bytesPerLine, s))    .Aggregate("", (s, i) => s + i + Environment.NewLine);Console.WriteLine(hexDump); Here is a sample output:000000: FF FE 3C 00 3F 00 78 00 6D 00 6C 00 20 00 76 00000016: 65 00 72 00 73 00 69 00 6F 00 6E 00 3D 00 22 00000032: 31 00 2E 00 30 00 22 00 20 00 65 00 6E 00 63 00000048: 6F 00 64 00 69 00 6E 00 67 00 3D 00 22 00 75 00000064: 3E 00Eric White reports that he typically notices that declarative code is only 20% as long as imperative code.

• Is it a "pattern smell" to put getters like "FullName" or "FormattedPhoneNumber" in your model?

  - by DanM

  I'm working on an ASP.NET MVC app, and I've been getting into the habit of putting what seem like helpful and convenient getters into my model/entity classes. For example: public class Member { public int Id { get; set; } public string FirstName { get; set; } public string LastName { get; set; } public string PhoneNumber { get; set; } public string FullName { get { return FirstName + " " + LastName; } } public string FormattedPhoneNumber { get { return "(" + PhoneNumber.Substring(0, 3) + ") " + PhoneNumber.Substring(3, 3) + "-" + PhoneNumber.Substring(6); } } } I'm wondering people think about the FullName and FormattedPhoneNumber getters. They make it very easy to create standardized data formats throughout the app, and they seem to save a lot of repeated code, but it could definitely be argued that data format is something that should be handled in mapping from model to view-model. In fact, I was originally applying these data formats in my service layer where I do my mapping, but it was becoming a burden to constantly have to write formatters then apply them in many different places. E.g., I use "Full Name" in most views, and having to type something like model.FullName = MappingUtilities.GetFullName(entity.FirstName, entity.LastName); all over the place seemed a lot less elegant than just typing model.FullName = entity.FullName (or, if you use something like AutoMapper, potentially not typing anything at all). So, where do you draw the line when it comes to data formatting. Is it "okay" to do data formatting in your model or is that a "pattern smell"? Note: I definitely do not have any html in my model. I use html helpers for that. I'm strictly talking about formatting or combining data (and especially data that is frequently used).

• Google play game services and Facebook integration in one game

  - by Ineentho

  We are creating a cross platform game for iOS and Android. We have thought about how and with which services we should integrate achievements and scoreboards with. For the iOS part, we are pretty sure that this how we want to do, in order from when the user opens the app for the first time: Connect with Game Center (Should be automatic, the user shouldn't even notice?) We will also get the players nickname for public scoreboards here. Ask if the user wants to connect with Facebook so that we can compare the players highscores with their friends. We could add Google play game services there as well, but I don't feel like that adds anything to the experience for the end user. Now comes the tricky part: Android We thought that we could do just like for iOS, except that we replace Game Center with Google Play Game Services. However, unlike Game Center, Game Services will ask the user to log in to their Google+ account and allow us to access their account. So now, what we have is a double login, first with Google+ and then with Facebook. What will users think about that? Should we scrap Play Services entirely and just ask the user for a nickname within our app and user Facebook for achievements?

• HTML5 game engine for a 2D or 2.5D RPG style "map walk"

  - by stargazer

  please help me to choose a HTML5 game engine or Javascript libraries I want to do the following in the game: when the game starts a part the huge map (full size of the map: about 7 screens) is shown. The map itself is completely designed in the editor mapeditor.org (or in some comparable editor - if you know a good alternative to mapeditor.org - let me know) and loaded at runtime or at design time. The game engine should support loading of isometric maps (well, in worst case only orthogonal maps will be sufficient) both "tile layer" and "object layer" from mapeditor.org should be supported. Scrolling/performance of this map should be fast enough. The map and the game should be either in 2D (orthogonal map) or in 2.5D (isometric map) The game engine should support movement of sprites with animation. Let say I have a sprite for "human" with animation sequences showing "walking" in 8 directions - it should be imported into game engine and should "walk" on the map without writing a lot of Javascript code. Automatic scrolling of the map the "human" nears the screen border. Collision detection, "solid" objects. The mapeditor.org supports properies on tiles. Let say I assign a "solid" property to some tiles in editor. It should be easy to check this "solid" property in the game engine and implement kind of "solid" behavior, so the animanted sprites do not walk through the walls. Collision detection - it should be easy to implement some custom functionality like "when sprite A is close to sprite B - call this function" Showing "dialogs" or popup windows on top of the map - should be easy to implement. Cross-browser audio support - (it is implemented quite well in construct 2 from scirra, so I'm looking for the comparable audio quality) The game itself is a king of RPG but without fighting scenes and without huge "inventory". The main character just walking on the map, discovers some things, there are dialogs and sounds. The functionality of this example from sprite.js http://batiste.dosimple.ch/sprite.js/tests/mapeditor/map_reader.html is very close to what I'm developing. But I'm not a Javascript guru (and a very lazy guy) and would like to write even less Javascript code as in the example...

• Geometry Shader: distortions

  - by Christophe Lionet

  This is a cross-question from Stack Overflow, I thought it would be more appropriate here. There is a lot of code I could be posting. To avoid overloading the page with code, I will post any part of the code if requested. I am working from the ParticleGS DirectX10 sample, to build a geometry shader based particle system in DirectX 11. Using the sample code, and changing it to my liking, I am able to draw a single quad (which is essentially one particle constantly recreating itself). However, I noticed a problem which was similar to one I once had: the rendered shape is distorted. Here is a video showcasing what is happening. http://youtu.be/6NY_hxjMfwY Now, I used to have this issue when using several effects together, when I realised that I needed to explicitely set the geometry shader to null for the other effects. I solved this problem, as you can see in the video, as the rest of the scene is drawing properly. Note that some sides are being culled somehow, although I turned off culling in my main render state. The texturing is fine too, the texture draws with appropriate proportions relative to the quad. I really don't see what I could be doing wrong here... what would cause the geometry shader to behave in such a way? Again, I will post any piece code you will request.

• How can I read data from a generated pointcloud, but from an other perspective of the camera? [migrated]

  - by Vlad Lata

  Basically what I'm trying to do is as follows: I have a software that generates and shows a pointcloud by analyzing Time-of-Flight data (Z-Data). This software has a GUI that delivers this pointcloud on a grid, and you can watch it and adjust the camera to change the perspective, or apply filtering to it and so on. Since the Z-data was recorder through a stereoscopic system, I want to obtain a perspective transformation. My idea was to simply change the position of the camera in the GUI and than add a button that sais (ex. New Perspective) that calls a function that would measure the distances from the existing pointcloud to the camera I'm viewing it from. Of course this would generate some occluded areas, but I want this to happen. And now the main question is: How can I do that? Are there any functions in OpenGL that measure the distance from an object to a camera, or is it even possible to do something like his? Or has someone some other idea? P.S. The software uses the qt sdk and opengl

• What is an effective git process for managing our central code library?

  - by Mathew Byrne

  Quick background: we're a small web agency (3-6 developers at any one time) developing small to medium sized Symfony 1.4 sites. We've used git for a year now, but most of our developers have preferred Subversion and aren't used to a distributed model. For the past 6 months we've put a lot of development time into a central Symfony plugin that powers our custom CMS. This plugin includes a number of features, helpers, base classes etc. that we use to build custom functionality. This plugin is stored in git, but branches wildly as the plugin is used in various products and is pulled from/pushed to constantly. The repository is usually used as a submodule within a major project. The problems we're starting to see now are a large number of Merge conflicts and backwards incompatible changes brought into the repository by developers adding custom functionality in the context of their own project. I've read Vincent Driessen's excellent git branching model and successfully used it for projects in the past, but it doesn't seem to quite apply well to our particular situation; we have a number of projects concurrently using the same core plugin while developing new features for it. What we need is a strategy that provides the following: A methodology for developing major features within the code repository. A way of migrating those features into other projects. A way of versioning the core repository, and of tracking which version each major project uses. A plan for migrating bug fixes back to older versions. A cleaner history that's easier to see where changes have come from. Any suggestions or discussion would be greatly appreciated.

• How to set TextureFilter to Point to make example Bloom filter work?

  - by Mr Bell

  I have simple app that renders some particles and now I am trying to apply the bloom shader from the xna samplers ( http://create.msdn.com/en-US/education/catalog/sample/bloom ) to it, but I am running into this exception: "XNA Framework HiDef profile requires TextureFilter to be Point when using texture format Vector4." When the BloomComponent tries to end the sprite batch in the DrawFullscreenQuad method: spriteBatch.Begin(0, BlendState.Opaque, SamplerState.PointWrap, null, null, effect); spriteBatch.Draw(texture, new Rectangle(0, 0, width, height), Color.White); spriteBatch.End(); //<------- Exception thrown here It seems to be related to the pixel shaders that I am using to animate the particle. In a nutshell, I have a texture2d in vector4 format that holds particle positions, and another one for velocities. Here is a snippet from that area: GraphicsDevice.SetRenderTarget(tempRenderTarget); animationEffect.CurrentTechnique = animationEffect.Techniques[technique]; spriteBatch.Begin(SpriteSortMode.Immediate, BlendState.Opaque, SamplerState.PointWrap, DepthStencilState.DepthRead, RasterizerState.CullNone, animationEffect); spriteBatch.Draw(randomValues, new Rectangle(0, 0, width, height), Color.White); spriteBatch.End(); What I comment out the code that calls the particle animation pixel shaders the bloom component runs fine. Is there some state that I need to reset to make the bloom work?

• Functional Languages that compile to Android's Dalvik VM?

  - by Berin Loritsch

  I have a software problem that fits the functional approach to programming, but the target market will be on the Android OS. I ask because there are functional languages that compile to Java's VM, but Dalvik bytecode != Java bytecode. Alternatively, do you know if the dx utility can intelligently convert the .class files generated from functional languages like Scala? Edit: In order to add a bit more helpfulness to the community, and also to help me choose better, can I refine the question a bit? Have you used any alternate languages with Dalvik? Which ones? What are some "gotchas" (problems) that I might run into? Is performance acceptable? By that, I mean the application still feels responsive to the user. I've never done mobile phone development, but I grew up on constrained devices and I'm under no illusion that there is a cost to using non-standard languages with the platform. I just need to know if the cost is such that I should shoe-horn my approach into default language (i.e. apply functional principles in the OOP language).

• 11 ADF Mobile Apps in 30 Hours

  - by Shay Shmeltzer

  The Oracle ADF Mobile team took part in a special "hackathon" this weekend, where 11 teams of new college hires who joined Oracle lately spent 30 hours building enterprise mobile applications leveraging ADF Mobile. One important thing to note - none of the participants worked with Oracle ADF Mobile before! In fact 90% of them didn't develop with ADF previously. All they had is a 2 hour training session before the event - and that's all they needed. From that point on they were able to build great cross device mobile applications. So what did they build? Here are some examples: A mileage expense tracking system: An ad campaign analysis system An expense report entry system Bug tracking system with data analysis: Carpooling social system: College Hiring system with CV scanning: Shipment management system for Farmers: Project time entry system: For sale post-it system (with item location): Conference event experience system with conference map and twitter feed integration: It was great to see how fast developers were able to learn and leverage ADF Mobile - and how creative the teams were. Here they are in action: So how about you? What would you build next? What would be your first ADF Mobile application? Start today!

• Output = MAXDOP 1

  - by Dave Ballantyne

  It is widely know that data modifications on table variables do not support parallelism, Peter Larsson has a good example of that here .  Whilst tracking down a performance issue,  I saw that using the OUTPUT clause also causes parallelism to not be used. By way of example,  first lets create two tables with a simple parent and child (one to one) relationship, and then populate them with 100,000 rows. Drop table ParentDrop table Childgocreate table Parent(id integer identity Primary Key,data1 char(255))Create Table Child(id integer Primary Key)goinsert into Parent(data1)Select top 1000000 NULL from sys.columns a cross join sys.columns b insert into ChildSelect id from Parentgo If we then execute update Parent set data1 =''from Parentjoin Child on Parent.Id = Child.Id where Parent.Id %100 =1 and Child.id %100 =1 We should see an execution plan using parallelism such as   However,  if the OUTPUT clause is now used update Parent set data1 =''output inserted.idfrom Parentjoin Child on Parent.Id = Child.Id where Parent.Id %100 =1 and Child.id %100 =1   The execution plan shows that Parallelism was not used Make of that what you will, but i thought that this was a pretty unexpected outcome. Update : Laurence Hoff has mailed me to note that when the OUTPUT results are captured to a temporary table using the INTO clause,  then parallelism is used.  Naturally if you use a table variable then there is still no parallelism

• Duck checker in Python: does one exist?

  - by elliot42

  Python uses duck-typing, rather than static type checking. But many of the same concerns ultimately apply: does an object have the desired methods and attributes? Do those attributes have valid, in-range values? Whether you're writing constraints in code, or writing test cases, or validating user input, or just debugging, inevitably somewhere you'll need to verify that an object is still in a proper state--that it still "looks like a duck" and "quacks like a duck." In statically typed languages you can simply declare "int x", and anytime you create or mutate x, it will always be a valid int. It seems feasible to decorate a Python object to ensure that it is valid under certain constraints, and that every time that object is mutated it is still valid under those constraints. Ideally there would be a simple declarative syntax to express "hasattr length and length is non-negative" (not in those words. Not unlike Rails validators, but less human-language and more programming-language). You could think of this as ad-hoc interface/type system, or you could think of it as an ever-present object-level unit test. Does such a library exist to declare and validate constraint/duck-checking on Python-objects? Is this an unreasonable tool to want? :) (Thanks!) Contrived example: rectangle = {'length': 5, 'width': 10} # We live in a fictional universe where multiplication is super expensive. # Therefore any time we multiply, we need to cache the results. def area(rect): if 'area' in rect: return rect['area'] rect['area'] = rect['length'] * rect['width'] return rect['area'] print area(rectangle) rectangle['length'] = 15 print area(rectangle) # compare expected vs. actual output! # imagine the same thing with object attributes rather than dictionary keys.
