  • backface culling error (in world space)

    - by acrilige
    I write simple software renderer. In my pipeline i have stage of backface culling. But looks like it has some error (see picture). I perform culling right after world transformation (is it correct?). (i can't insert picture in post coz i don't have enough points, so i just upload it (cube model): http://imageshack.us/photo/my-images/705/bcerror.png/) Vector3F view_dir(0.0f, 0.0f, 1.0f); std::vector<Triangle> to_remove; for (Triangle &t : m_triangles) { Vector4F e1 = t.v2 - t.v1; Vector4F e2 = t.v3 - t.v1; Vector3F normal( e1.y * e2.z - e1.z * e2.y, e1.z * e2.x - e1.x * e2.z, e1.x * e2.y - e1.y * e2.x ); normal.Normalize(); float dot = Dot(view_dir, normal); if (dot <= 0) to_remove.push_back(t); } for (Triangle& t : to_remove) m_triangles.erase(std::remove(m_triangles.begin(), m_triangles.end(), t), m_triangles.end()); Camera sits in origin and points in screen (RH). What is the reason? For better explanation i upload picture with cube rotation screenshots: http://imageshack.us/photo/my-images/842/bcmove.png/ UPDATED: The error occurs only when triangle has non-zero offset from origin UPDATED 2: If i process backface culling in clip space (after transforming all vertices with view and projection matrix), and just check z coordinate of triangle normal - it works perfect... Can i perform culing RIGHT BEFORE view/proj transforms? In this case looks like culling will not depends of projection and it's not right?.. UPDATED 3: I found answer and will post it in two hours - again coz of reputation lack.

  • What have you learned from the bugs you helped discover and fix?

    - by Ethel Evans
    I liked the core of this question, and wanted to re-ask it in a way that made it less about 'fun' and more about 'What do these past mistakes tell us about how we can write and test software better?' As an SDET, I'm always looking for anecdotes about new and interesting ways that programs can fail. I've learned a lot from these tales in the past, and would like to get that from the intelligent people in this community as well. I'd be interested in hearing what the issue was, how it was caught, if you think there was anything that could have reasonably done to catch it earlier or to avoid the same issue on later projects, and any other interesting lessons you took away from this bug. Please only write about bugs you personally were involved with, ideally on a project you worked on (e.g., no "10 years before I was born, this happened and it was FUNNY!" answers). Please vote up answers that are thought-provoking or could change how you develop or test in some way, so this isn't just 'social fun'. Try to avoid voting up something just because it was funny.

  • Am I obligated to install Windows Genuine Advantage Notifications to receive all Microsoft updates?

    - by Pieter
    Do I have to install WGA Notifications to receive all Microsoft updates? I currently don't have it on my hard drive, and I get a notification from Microsoft Update urging me to validate my copy of Windows XP. If I don't validate my copy, I don't get all updates. When I click the link however, I get an ActiveX error message. (Yes, I'm doing this in IE8.) Could this have something to do with my decision not to install WGA Notifications?

  • As my first professional position should I take it at a start-up or a better known company? [closed]

    - by Carl Carlson
    I am a couple of months removed from graduating with a CS degree and my gpa wasn't very high. But I do have aspirations of becoming a good software developer. Nevertheless I got two job offers recently. One is with a small start-up and the other is with a military contractor. The military contractor asked for my gpa and I gave it to them. The military contracting position is in developing GIS related applications which I was familiar with in an internship. After receiving an offer from the military contractor, I received an offer from the start-up after the start-up asked me how much the offer was from the military contractor. So the pay is even. The start-up would require I be immediately thrust into it with only two other people in the start-up currently and I would have to learn everything on my own. The military contractor has teams and people who know what their doing and would be able to offer me guidance. Seeing as how I have been a couple of months removed from school and need something of a refresher is it better than I just dive into the start-up and diversify what I've learned or be specialized on a particular track? Some more facts about the start-up: It deals with military contracts as well and is in Phase 2 of contracts. It will require I learn a diverse amount of technologies including cyber security, android development, python, javascript, etc. The military contractor will have me learn more C#, refine my Java, do javascript, and GIS related technologies. I might as well come out and say the military contractor is Northrop Grumman and more or less offered me less money than the projected starting salary from online salary calculators. But there is the possibility of bonuses, while the start-up doesn't include the possibility of bonuses. I think benefits for both are relatively the same.

  • How to understand computer science as a whole?

    - by MrCellophane
    I am a college student in Computer Science, I have been studying CS for a long time. But even till today, I still feel so confused about a lot of things. First of all, I have solid foundation in alg, data structure, and OOP, but I don't have a clear understanding of the whole system of the subject. I studied database, alg, data structure, OOP, network, software engineering, OS, and a lot of courses. I know what they are, but I don't know how to connect them together. Is there a way to have a clear understanding of the architecture of the subject? And is there a way to know what technology is used to do what? For example, in interviews, when people ask me alg, data str, Java, OS or any other specific field, I could answer, but when they ask some other very general about the field, I have no idea. Well, I know my question maybe a little bit confusing, but what my situation is I don't even know how to ask a clear question. I don't know my question, it's totally a mess in my head. Is there a way to make it clear?

  • Are R&D mini-projects a good activity for interns?

    - by dukeofgaming
    I'm going to be in charge of hiring some interns for our software department soon (automotive infotainment systems) and I'm designing an internship program. The main productive activity "menu" I'm planning for them consists of: Verification testing Writing Unit Tests (automated, with an xUnit-compliant framework [several languages in our projects]) Documenting Code Updating wiki Updating diagrams & design docs Helping with low priority tickets (supervised/mentored) Hunting down & cleaning compiler/run-time warnings Refactoring/cleaning code against our coding standards But I also have this idea that having them do small R&D projects would be good to test their talent and get them to have fun. These mini-projects would be: Experimental implementations & optimizations Proof of concept implementations for new technologies Small papers (~2-5 pages) doing formal research on the previous two points Apps (from a mini-project pool) These kinds of projects would be pre-defined and very concrete, although new ideas from the interns themselves would be very welcome. Even if a project is too big or is abandoned, the idea would also be to lay the ground work so they can be retaken by another intern or intern team. While I think this is good in concept, I don't know if it could be good in practice, as obviously this would diminish their productivity on "real work" (work with immediate value to the company), but I think it could help bring aboard very bright people and get them to want to stay in the future (which, I think, is the end goal for any internship program). My question here is if these activities are too open ended or difficult for the average intern to accomplish and if R&D is an efficient use of an interns time or if it makes more sense for to assign project work to interns instead.

  • What issues ensue from having multiple versions of Office installed?

    - by Michael Sorens
    My ultimate question is embodied in the title but I thought it might be helpful to others if I detail what instigated my inquiry and my examination of the problem. To me, the first rule of software updates is Primum non nocere -- first, do no harm. So with my Windows 7 system containing both Office 2003 and Office 2010 I blithely proceeded to install this month's updates from Microsoft, containing updates for both versions of Office. While Microsoft officially does not recommend running multiple versions (see, for example, Running Multiple Versions of Microsoft Excel it is possible; I have had two versions installed for a year or more and have never run into an issue before. One thing that is always mentioned is installation order, i.e., the one you want to open files by default should be installed last. I wanted 2010 as my default so I had indeed installed 2003 first then, years later, 2010. So with this round of Windows updates, either it installed patches to 2010 before 2003, knocking out the file association, or the 2003 patch was more comprehensive, in the sense of touching the file association while the 2010 did not. In any case, after updates, double-clicking a .xls file opened 2003 rather than 2010. Web search indicated either: Use the file associations control panel to re-associate .xls files with the correct version of excel. I looked at this first, but it showed what seemed to be an unversioned "Excel" associated with .xls files so I did not check further. (This turned out to be an error on my part; more later.) Re-install versions in the desired order; I find this unreasonable. Run the repair option of the Office installer on the desired version; still seems more work than one should need. Run excel from the command line with "/regserver" on the one to be the default and "/unregserver" on the other. Good idea, but further search indicated that neither 2007 nor 2010 support "/regserver" contrary to some posts (e.g. Default Program With Multiple Versions Installed). Since this was a Windows Update issue and Microsoft provides free support for such, I inquired there as well, but succeeded only in getting the suggestion to uninstall all other versions, period; not acceptable to me. What worked for me was going back to the file associations control panel and manually selected the Office 2010 version of Excel. While it appeared no different in the control panel, it did fix the double-click issue. So if all it takes is this simple fix after an update, I can live with that. What I am wondering is: Has anyone seen any other problems related to having multiple versions of Office installed?

  • Which pattern is best for large project

    - by shamim
    I have several years of software development experience, but I am not a keen and adroit programmer, to perform better I need helping hands. Recently I engaged in an ERP project. For this project want a very effective structure, which will be easily maintainable and have no compromise about performance issue. Below structures are now present in my old projects. Entity Layer BusinessLogic Layer. DataLogic Layer UI Layer. Bellow picture describe how they are internally connected. For my new project want to change my project structure, I want to follow below steps: Core Layer(common) BLL DAL Model UI Bellow picture describe how they are internally connected. Though goggling some initial type question’s are obscure to me, they are : For new project want to use Entity framework, is it a good idea? Will it increase my project performance? Will it more maintainable than previous structure? Entity Framework core disadvantages/benefits are? For my project need help to select best structure. Will my new structure be better than the old one?

  • Sucking Less Every Year ?

    - by AdityaGameProgrammer
    Sucking Less Every Year A trail of thought that had been on my mind for a while Quoting directly from the post I've often thought that sucking less every year is how humble programmers improve. You should be unhappy with code you wrote a year ago. If you aren't, that means either A) you haven't learned anything in a year, B) your code can't be improved, or C) you never revisit old code. All of these are the kiss of death for software developers. How often does this happen or not happen to you? How long before you see an actual improvement in your coding ? month, year? Do you ever revisit Your old code? How often does your old code plague you? or how often do you have to deal with your technical debt. It is definitely very painful to fix old bugs n dirty code that we may have done to quickly meet a deadline and those quick fixes ,some cases we may have to rewrite most of the application/code. No arguments about that. Some of the developers i had come across argued that they were already at the evolved stage where their coding doesn't need improvement or cant get improved anymore. Does this happen? If so how many years into coding on a particular language does one expect this to happen?

  • Windows 7 driver search woefully slow

    - by askvictor
    Any thoughts on why the driver search (when installing a usb device) on windows 7 is woefully slow? Even when I click to disable trying to get a driver from windows update, it still takes 10min+ to either find a driver, or bail out. Is there a way to speed this up, or alternately, disable windows trying to find drivers, so I can manually install them in device manager?

  • Is file permission secured when it transferred from Ubuntu to Windows?

    - by Gaurav_Java
    I am having 9GB text file which is encrypted . This file contains some confidential data . Which is on my system(Ubuntu) and my external HDD (ntfs) . This file get daily updated and then encrypted . But it has to be shared among 2-3 (Windows) person. I defined permission so that no other person can even read this file(chmod 660). It is too large file, so I can't upload it anywhere and it get updated daily basis. But this file travel on Windows OS and Ubuntu also. Even I am having copy of this on my personal computer. Recently it was deleted by some other user over Windows . I just want to know how can I set permission over that file so that it cannot be deleted from any other operating system. If someone delete this file, then I am having data old for couple of days, which is only on my system. I gone through this question it says there is nothing. And from this question I am not able to understand how can I protect it. Can I do anything for preventing this file from being deleted. Then how can I secure this files from getting deleted any suggestion or software or ideas. Maybe I sound silly or this is stupid question. Please don't close it, thanks for any suggestion or solution.

  • Photoshop alternative with same keyboard shorcuts

    - by user292254
    tldr; Is there a program with the same keyboard shortcuts and/or user interface as PS. I know the "photoshop alternative" question has been asked so many times, but I feel this variant is worth the time to ask. I am a web designer and have been using PS daily on a windows or mac machine for about 10 years, but I do most of my development in linux. The only thing that has been keeping me from the full switch to linux is PS. I have tried many alternatives, including GIMP, but I feel the barrier to entry is too high for one reason and one reason only, the keyboard shortcuts. Over the years I have become very adept and quick in the use of PS because of keyboard shortcuts and muscle memory. I realize that many shortcuts can be customized, but many actions are just too different from PS. So my question is what programs are out there that are the closest to PS in keyboard shortcuts and interface. I don't care if I have to do a bunch of customization to get it as close as possible, but I just can't take too much time to learn a completely new workflow. Of course I realize that any software will take time and effort, I just want to make that time/effort as minimal as possible. Thanks in advance for your responses. edit I should tell you the most important features and workflow I use on a daily basis are, Smart objects, linked documents, save for web and devises.

  • How does a segment-based rendering engine (as in Descent) work?

    - by Calmarius
    As far as I know Descent was one of the first games that featured a fully 3D environment, and it used a segment based rendering engine. Its levels are built from cubic segments (these cubes may be deformed as long as it remains convex and sides remain roughly flat). These cubes are connected by their sides. The connected sides are traversable (maybe doors or grids can be placed on these sides), while the unconnected sides are not traversable walls. So the game is played inside of this complex. Descent was software rendered and it had to be very fast, to be playable on those 10-100MHz processors of that age. Some latter levels of the game are huge and contain thousands of segments, but these levels are still rendered reasonably fast. So I think they tried to minimize the amount of cubes rendered somehow. How to choose which cubes to render for a given location? As far as I know they used a kind of portal rendering, but I couldn't find what was the technique used in this particular kind of engine. I think the fact that the levels are built from convex quadrilateral hexahedrons can be exploited.

  • Installing Visual Studio 2010 SP1 or Windows Phone tools in your VM (danger!)

    - by Jeff
    If you've read my blog for any amount of time, you probably know that I tend to develop stuff in a Parallels VM on a Mac. It's how I roll. I like VM's because I can trash them and do really stupid things with beta software. That said, there is a pain point that doesn't seem that well documented when it comes to installing stuff in this scenario.The WP7 tools, and SP1 for Visual Studio 2010 (perhaps only if you already have the WP7 tools installed, I'm not sure), do something strange on install. As if it weren't already a long and slow installation, for reasons I don't understand, the installer fires up an instance of Windows Phone Emulator. As you may already know, the emulator doesn't run in a VM, because it is itself a VM, apparently. What it will do is fire up your CPU, make your comprooder hot and make the fans blow harder.I found this out accidentally, as I started the (slow) phone tool installation once, and walked away. An hour and a half later, I came back to find it hadn't finished. But it was hot and the CPU was pegged, so I fired up the task manager to find XDE.exe, the phone emulator, cranking away. I had to kill it several times, and eventually the install finished. It fired up just once in the SP1 install, but it still had the same hanging effect.I can't for the life of me figure out why it does this. In a VM, I can connect the phone to it and use that, so I don't need the emulator. But this install, firing up the emulator, will make it choke until you kill the XDE.exe process. Watch out!

  • GUI based backup utility [closed]

    - by Chethan S.
    Possible Duplicate: Comparison of backup tools I have read favorable reviews for 'Back In Time' for the purpose stated above. Still I am posting this question as I have some demands in my mind. Few years back I was using ThinkVantage Rescue and Recovery by IBM on my Lenovo PC under Windows. That provided me nice features like compressed backups, boot time options - OS Repair, Restore entire OS, restore entire system to an older date, restore individual files etc. Out of these the feature I liked the most was compressed backups. Similar features are available in software like Norton Ghost too. In Back In Time I was surprised to see that the snapshot takes up same amount of space as that of the original contents, no compression at all. Furthermore, I was not able to find options to change the compression ratio etc. under settings. According to me compression of backups is a must have feature. Therefore, can anyone suggest me any other utility which can serve the purpose. I insist on GUI based tool since I don't want to mess up with backups!

  • Using pkexec policy to run out of /opt/

    - by liberavia
    I still try to make it possible to run my app with root priveleges. Therefore I created two policies to run the application via pkexec (one for /usr/bin and one for /opt/extras... ) and added them to the setup.py: data_files=[('/usr/share/polkit-1/actions', ['data/com.ubuntu.pkexec.armorforge.policy']), ('/usr/share/polkit-1/actions', ['data/com.ubuntu.extras.pkexec.armorforge.policy']), ('/usr/bin/', ['data/armorforge-pkexec'])] ) additionally I added a startscript which uses pkexec for starting the application. It distinguishes between the two places and is used in the Exec-Statement of the desktopfile: #!/bin/sh if [ -f /opt/extras.ubuntu.com/armorforge/bin/armorforge ]; then pkexec "/opt/extras.ubuntu.com/armorforge/bin/armorforge" "$@" else pkexec `which armorforge` "$@" fi If I simply do a quickly package everything will work right. But if I package with extras option: quickly package --extras the Exec-statement will be exchanged. Even if I try to simulate the pkexec call via armorforge-pkexec It will aks for a password and then returns this: andre@andre-desktop:~/Entwicklung/Ubuntu/armorforge$ armorforge-pkexec (armorforge:10108): GLib-GIO-ERROR **: Settings schema 'org.gnome.desktop.interface' is not installed Trace/breakpoint trap (core dumped) So ok, I could not trick the opt-thing. How can I make sure, that my Application will run with root priveleges out of opt. I copied the way of using pkexec from synaptic. My application is for communicating with apparmor which currently has no dbus interface. Else I need to write into /etc/apparmor.d-folder. How should I deal with the opt-build which, as far as I understand, is required to submit my application to the ubuntu software center. Thanks for any hints and/or links :-)

  • Excel 2010: dynamic update of drop down list based upon datasource validation worksheet changes

    - by hornetbzz
    I have one worksheet for setting up the data sources of multiple data validation lists. in other words, I'm using this worksheet to provide drop down lists to multiple other worksheets. I need to dynamically update all worksheets upon any of a single or several changes on the data source worksheet. I may understand this should come with event macro over the entire workbook. My question is how to achieve this keeping the "OFFSET" formula across the whole workbook ? Thx To support my question, I put the piece of code that I'm trying to get it working : Provided the following informations : I'm using such a formula for a pseudo dynamic update of the drop down lists, for example : =OFFSET(MyDataSourceSheet!$O$2;0;0;COUNTA(MyDataSourceSheet!O:O)-1) I looked into the pearson book event chapter but I'm too noob for this. I understand this macro and implemented it successfully as a test with the drop down list on the same worksheet as the data source. My point is that I don't know how to deploy this over a complete workbook. Macro related to the datasource worksheet : Option Explicit Private Sub Worksheet_Change(ByVal Target As Range) ' Macro to update all worksheets with drop down list referenced upon ' this data source worksheet, base on ref names Dim cell As Range Dim isect As Range Dim vOldValue As Variant, vNewValue As Variant Dim dvLists(1 To 6) As String 'data validation area Dim OneValidationListName As Variant dvLists(1) = "mylist1" dvLists(2) = "mylist2" dvLists(3) = "mylist3" dvLists(4) = "mylist4" dvLists(5) = "mylist5" dvLists(6) = "mylist6" On Error GoTo errorHandler For Each OneValidationListName In dvLists 'Set isect = Application.Intersect(Target, ThisWorkbook.Names("STEP").RefersToRange) Set isect = Application.Intersect(Target, ThisWorkbook.Names(OneValidationListName).RefersToRange) ' If a change occured in the source data sheet If Not isect Is Nothing Then ' Prevent infinite loops Application.EnableEvents = False ' Get previous value of this cell With Target vNewValue = .Value Application.Undo vOldValue = .Value .Value = vNewValue End With ' LOCAL dropdown lists : For every cell with validation For Each cell In Me.UsedRange.SpecialCells(xlCellTypeAllValidation) With cell ' If it has list validation AND the validation formula matches AND the value is the old value If .Validation.Type = 3 And .Validation.Formula1 = "=" & OneValidationListName And .Value = vOldValue Then ' Debug ' MsgBox "Address: " & Target.Address ' Change the cell value cell.Value = vNewValue End If End With Next cell ' Call to other worksheets update macros Call Sheets(5).UpdateDropDownList(vOldValue, vNewValue) ' GoTo NowGetOut Application.EnableEvents = True End If Next OneValidationListName NowGetOut: Application.EnableEvents = True Exit Sub errorHandler: MsgBox "Err " & Err.Number & " : " & Err.Description Resume NowGetOut End Sub Macro UpdateDropDownList related to the destination worksheet : Sub UpdateDropDownList(Optional vOldValue As Variant, Optional vNewValue As Variant) ' Debug MsgBox "Received info for update : " & vNewValue ' For every cell with validation For Each cell In Me.UsedRange.SpecialCells(xlCellTypeAllValidation) With cell ' If it has list validation AND the validation formula matches AND the value is the old value ' If .Validation.Type = 3 And .Value = vOldValue Then If .Validation.Type = 3 And .Value = vOldValue Then ' Change the cell value cell.Value = vNewValue End If End With Next cell End Sub

  • What makes you look like a bad developer (ie a hacker) [on hold]

    - by user134583
    This comes from a lot of people about me, so I have to look at myself. So I would wonder what make one a bad developer (ie a hacker). These are a few things about me I used IDE intensively, all features, you name it: auto-completion, refactoring, quick fixes, open type, view hierarchy, API documentation, etcc When I deal with writing code for a project in domain I am not used to (I can't have fluency in this, this is new), I only have a very rough high level ideas. I don't use the standard modeling diagrams for early detail planning. Unorthodox diagrams that I invented when I need to draw the design in details. I don't use UML or similar, I find them not enough. I divide the sorts of diagram I drew into 3 types. Very high level diagrams which probably can be understood by almost anybody. Data entity diagram used for modeling data objects only (like ER diagrams and tree for inheritances and composition). Action diagrams for agents/classes and their interactions on data objects they contain. Constantly changing the interface (public methods) between interacting agents/classes if the need arises. I am more refrained when the interface and the module have matured Write initial concept code in a quick hackie way just so that the module works in the general cases so that I can play around with it. The module will be re-factored intensively after playing around so I could see more corner cases that I couldn't or (wouldn't want) anticipate before writing code. Using JUnit for integration-like test by using TestSuite class and ordering Unit test classes in the suite Using debugger almost anytime there is a problem instead of reading the code Constantly search on the internet for how to do some thing with some library that I haven't used a lot. So judgment, am I a bad developer? a hacker? Put in other words, to make sure this is not considered off-topic: - Is this bad practice to make your code too agile during incubating/prototyping phase of software development - Is it bad practice to use JUnit for integration testing, (I know there are other framework for integration testing, but those frameworks are for a specific products, not general)

  • Should i worry about company's Reputation before joining it...

    - by Shekhar_Pro
    My question is particularly in context of this Question asked recently on this site. I am a fresh graduate and would soon be applying for jobs. But the above mentioned question has raised concerns for me. Should i care about the company i am going to join. Specially since for me Yahoo is a very reputed corporation and i duly respect it, in fact i would be proud to work for it if given the chance. And the OP of the question was a Senior Software Engineer, i don't think something could have gone so wrong that he feels shame for have worked there. Well i won't like to have this situation in my career. Until now for me the criteria for approaching a company were like - it should have Good, knowledgeable and Experienced team, it should provide me with tasks that will always challenge me to think and learn more, etc. After all a task is task and you do always learn something from it. But in view of mentioned question should i also consider other things... Please give your answers and most importantly an opinion from your own experience.

  • SQLite UPSERT - ON DUPLICATE KEY UPDATE

    - by Alix Axel
    MySQL has something like this: INSERT INTO visits (ip, hits) VALUES ('127.0.0.1', 1) ON DUPLICATE KEY UPDATE hits = hits + 1; As far as I'm know this feature doesn't exist in SQLite, what I want to know is if there is any way to archive the same effect without having to execute two queries. Also, if this is not possible, what do you prefer: SELECT + (INSERT or UPDATE) or UPDATE (+ INSERT if UPDATE fails)
