• I need advice on how to debug a cluster

  - by alcor

  I'm the only developer of a complex critical software system, written in Visual C++ 2005. It's deployed on a classical Microsoft cluster scenario (active/passive), that has Windows Server 2003 R2. If a server A goes down, the other one (B) starts and take the ownership of its duties. You have to know that: both servers have the same Microsoft patches/fixes, same hardware, same everything. both servers use the same memory storage (a RAID-6 through fiber channel). this software has a main module who launch the peripheral modules. if a peripheral module crashes, the main module restarts it. When I switch the application in one of the two servers (let's say the B server) two of the peripheral modules of the main applications just started to crash apparently without reason about 2 seconds after the start of the peripheral module. What could I do to analyze/inspect/resolve this weird situation?

• Ruby on rails not popular in big international IT companies?

  - by maro

  I would like to ask you for advice more experienced ROR developers. I am new in programming and like to idea of ROR and I am before the decision on which programing language to specialize Java vs ROR. In the future I wish to learn for bigger international IT companies (IBM, Accenture etc.) but as I am reading their job openings, most of them are hiring Java, C++, .NET... Is the ROR used only in startups or also in bigger companies as well? What should be the reasons of their preference of Java over ROR?

• Garbage Collection Basics

  - by mikew_co

  Java Is an awesome programming language and platform. One of its better features is automatic garbage collection. Ever wondered how that works? I have written an online web course outlining the basics. Much of what is included has been published before in various white papers and such. However, this is updated for JDK 7 and includes some nice illustrations of the steps involved. Hope you like it. Garbage Collection Basics. A follow-on web course on the G1 garbage collector should follow in a week or so.

• What framework for text rating site?

  - by problemofficer

  I want to start a "rate my"-style site. The rated objects are mostly texts. I want it to be rather simple. Features I need: object rating (thumb up, thumb down) object comments object tags related object presentation based on tags user authentication and management private message system sanity checks for text inputs (i.e. prevention of code injections) cache open source runs on GNU/Linux I would gladly take something that is tailored for my scenario but a generic framework would be fine too. I simply don't want to write stuff like user authentication that is been written a million times and risking security flaws. Programming language is irrelevant but python/php preferred.

• How to handle situation of programmer stealing credit for your project [on hold]

  - by shorecc

  There is a coworker who has stolen credit for my work. I created a system that will show live statuses of printing machines throughout the plant. There was one glitch in it so the coworker made an improvement and then re-wrote the entire system (copying 90% of my code, yet he added a new piece of hardware then took over the project). Now he asks me programming questions from time to time. I don't mind teaching coworkers how to program, but since he has stolen my ideas and credit in the past I am reluctant to teach him all I know. Today he asks me for a particularly challenging algorithm for this system. His code now looks exactly like the way I would program! How would you handle the situation? How can I decline helping him without appearing to not being a team player?

• How to name a clamp function that only clamps from one side?

  - by dog_funtom

  Clamp() is a function that ensures that provided variable is in provided range. You can find such function in .NET, in Unity, and probably anywhere. While it is useful, I often need to clamp my value from one side only. For example, to ensure that float is always non-negative or always positive (like radius value from inspector). I used names ClampFromAbove() and ClampFromBelow(), but I wonder if such names is good or even grammatically valid in programming-English. Also, it probably make sense to distinguish non-negative case too. How'd you name such function? Something like EnsureNonNegative()? My intention is creating pair of extension methods and use them like this: var normalizedRadius = originalRadius.ClampFromBelow(0.0001); var distance = someVector.Magnitude.ClampFromAbove(maxDistance);

I have tried deleting the old auto entry for it in the network manager Tried disabling and enabling both the networking and the wireless through the network indicator. Disabled the networking through the hardware shortkut key thing [fn] + [F9] Attempting to connect to it as if it was a hidden network. I'm at a loss, how would I go about debugging and unborking my computer?

• Getting Started with 12.04 LTS Problems

  - by mark

  Okay previously I used ubuntu 10.04 in Desktops and Loved it! I bought a newer Toshiba Satellite with an i7 CPU, 8GB Ram, 1TB HD, first thing I tried to do was install Ubuntu 9 on it then I found out it was no longer Supported. (I gave my 10.04 disk away) So I tried installing Windows 7 and experienced SO MANY problems, I am going back to try 12.04. Starting all over again. After installing 12.04 Wireless was Detected yet said it was Disabled by a Hardware Switch. Went read through the Message Boards found Solution which was Sudo rf Kill All. Okay all excited I would finally get my Ubuntu to finally work I rushed back to my laptop from the internet cafe, and went looking for the TERMINAL input on my Ubuntu 12.04, and I cannot find the Terminal. If I can't find the TERMINAL how Can I enter any Sudo Stuff? So I guess the first question is Where is the Terminal Located in 12.04? Thank you.

• How to properly code in Unity? [on hold]

  - by Vincent B.

  I'm fairly new to Unity (yet I touched it and made a few proto with it) and I'd like to know how I'm supposed to work with it. I'm student in programming so I'm used to C/C++ with SDL/SFML, writing code and only using Input/Graphics/Network libs. I followed a few Unity guides and it was way more around drag & drop on scenes and a bit of scripting to activate it all, which disturbed me. So I fond a way to only use one GameObject and use a Singleton to launch code and display stuff (for 2d games at least). At the end of the day I make games not using "Instantiate" or such at all. Is it the right way ? Am I supposed to do this ? How much are your scenes populated (in a professional environment) ? When should I stop coding and start using the editor ?

• What kind of performance issues does multiple instances of the exact same object have on a game?

  - by lggmonclar

  I'm fairly new to programming, and I've pretty much learned all the things I know on the go, while working on projects. The problem is that there some things that I just don't know where to begin searching. My question is about performance, and how can multiple instances of the same object affect it -- Specifically, I'm talking about XNA's "GraphicsDevice" class. I have it instanced on four different parts of my game, and in three of those, the object has the exact same values for all the attributes. So, in that case, should I be using the same instance of GraphicsDevice, passing it as a parameter, even if I use it in different classes? I apologize if the question seems redundant, but like I said, I've taught myself most of what I know, so there are quite a few "holes" in my learning process.

• Ubuntu 12.04 x64 - Very slow response and sluggishness

  - by Murphy1138

  Recently updated to 12.04 x64 on my AMD HEX core 4GB system, over the last few days I feel that the overall system is sluggish/laggy , for instance hitting the dash button, the dash opens but the recent activity of files/videos etc is incredibly slow to populate, like wise in Nautilus and browsing my media, the file names are showing up but it takes an age to populate the "thumb" of the video, If I go into Gnome-shell the shell response is a little faster but again clicking on applications there is still a noticeable pause. I have the latest Nvidia Drivers loaded and I have very fast SATA drives, if I reboot into windows 7 the system is so much quicker in its response, I only use windows for games and Ubuntu is my main OS. 10.04/10.10/11.04 was Super quick and this was when the system still had a Duel Core Chip and a worse Nvidia card, 11.10 was pretty snappy, but 12.04 just feels bloated on each system I have installed it on. My hardware is more than up to the task so has anyone got any commands i can run to help diagnose the issue? Anyone else got the same problems? Thanks Murph

I'm sharing ubuntu with Windows 7 in my laptop, and after I install Ubuntu when I boot my laptop and choose ubuntu as my operating system the following error appears: Windows failed to start. A recent hardware or software change might be the cause. To fix the problem: Insert your windows installation disc and restart your computer Choose your language settings, and then click "Next." Click "Repair your computer." If you do not have this disc, contact your system administrator or computer manufacturer for assistance.

• I'm a PeopleSoft Developer. Should I learn other languages (C# Java...)?

  - by PSDev

  I've been doing PeopleSoft development for 2 years. Recently, I want to relocate and find out there are not that many PeopleSoft development out there. 90% of the vacant positions are contract type of jobs. I'd rather get a full time permanent position. In PS, I do a lot of maintenance rather than new programming. It does get very boring. Also, I'm not sure if Oracle will one day pull off the plug for PS. What language is in most demand and also offers above average salary? Is it C#, Java, Python, Perl, ...? Thanks.

• What should be learned for someone starting in Android Games?

  - by user14544

  I know this might be a little subjective. But I've read the other questions. A lot of answers kept on popping up like to use box2d, libgdx, andEngine, etc. So the real question is, what would be the best to start off with as a beginner. I have some experience with java code, just by reading about in the Oracle Docs. I've gone through Flash and Eclipse. When i mean gone through, i don't mean i have actually created my own game from Flash or Eclipse, but i just learn things here and there. Currently I'm reading Beginning Android for Beginners but I don't have the knowledge to implement my own Ideas into the game tutorials because of lack of experience. I'm looking for a way to learn how to program to create games for Android. While at the same time get experience from programming. I do not want to learn those drag and drop game making applications such as GameMaker.

• How is Sencha Touch performing on Android in practice?

  - by user14557

  I'm just about to start a project using Sencha Touch, and just done some minor testing on my HTC desire device. All tutorial videos at Vimeo seems to be using an iPhone emulator running on a Mac. Im not sure how fast this emulator is compared to a real iPhone device or even an real Android device, but from what i have experienced, it seems that my HTC desire is not performing that nicly as this emulator. All animations (sliding, fading, etc) seems abit laggy. You can easily notice that the FPS is much less than on the Vimeo videos. HTC desire is a relativly new and modern Android 2.2 phone, running with decent hardware, so im wondering if Sencha Touch is "ready" for the Android platform. Anybody with practical experience with Android and Sencha Touch ?

• writing 3d game [closed]

  - by user1432980

  I want to write a game as my final year diploma project.(I'm a 4th-year-student now so I've got a year and several months). But I don't know what to choose: either write my own game engine using DirectX9(10)(I don't like OpenGL) or use OGRE + PhysX(Don't like Unity) I'm more interested in writing my own game engine(but I wonder if I'll create engine on the same level as even Unreal 1.0 hah) but on the other side with PhysX I'll have advanced physics in my game and with OGRE I'll have good grahics. For 3d models I want to use Maya. What do you advise me to choose? As for me I've got a little DirectX experience,not bad C++ programming skills(but not expert's) and a little knowledge of Maya. My English isn't perfect either hah...

• Does Turing-complete implies possibility of malware? [closed]

  - by Mathematician82

  Is it possible to build an operating system that contains some Turing complete compiler (language?) but is unable to run any malware? Or is there any definition for a malware? This question popped on my mind as I was wondering why Windows has more malware than Linux. If Linux contains a C programming language and its compiler, I think it is possible to write a Linux program that works similarly than Windows viruses. But there are less malware for Linux than for Windows although there is a Wine for Linux to simulate Windows programs.

• OpenGL Beginner question

  - by nobby

  I'm new to OpenGL programming, but I can't find a good book to read or a tutorial, I've tried reading through the superbible or whatever its name is but it's kind of complicated to me. The tutorial at http://duriansoftware.com/joe/An-intro-to-modern-OpenGL.-Chapter-2.3:-Rendering.html is pretty ok but it doesn't cover what I need mostly, which is opengl math etc (such as projection matrix, view matrix, and so on). I'm fairly OK at C(++) (3+ years experience, I don't know if you would call that "good") What i basically want to do with OpenGL is, make a simple game (prefer 2D as a start and not 3D). Please suggest a good EBook to read and learn from.

• Configuring ethernet network

  Hi. I've got a wired network connection and if I'm using network manager (hereafter "NM") everything works fine except for the hardware address (it doesn't change). I'm thinking of using /etc/network/interfaces. So, I added some code and it looks like this: auto lo iface lo inet loopback auto eth1 iface eth1 inet static address #corresponding value netmask #corresponding value gateway #corresponding value hwaddress #corresponding value After restarting networking I get the following message: *Reconfiguring network interfaces... #here some help code appears Failed to bring up eth1. The default interface that works with NM is eth0. Please advise on how to handle the problem.
