• Can I randomly generate an endless road?

  - by y26jin

  So suppose we stand on a position(x0, y0) of a map. We can only move on the horizontal plane(no jump and stuff) but we can move forward, left, or right (in a discrete math way, i.e. integer movement). As soon as we move to the next position(x1, y1), everything around us is generated randomly by a program. We could be surrounded by one of mountain, lake, and road. We can only move on the road. The road is always 2D as the map itself. My question is, are we able to play this game endlessly? "End" means that we come across a dead end and the only way out is to go backward.

• 3 threads printing numbers of different range

  - by user875036

  This question was asked in an Electronic Arts interview: There are 3 threads. The first thread prints the numbers 1 to 10. The second thread prints the numbers 11 to 20. The third thread prints the numbers from from 21 to 30. Now, all three threads are running. The numbers are printed in an irregular order like 1, 11, 2, 21, 12 etc. If I want numbers to be printed in sorted order like 1, 2, 3, 4..., what should I do with these threads?

• What should I learn next?

  - by Krysten

  I am a CS major. I've taken 2 courses in C (Intro to C and CS1) and 1 introductory course to OOP with Java. I really like Java and feel that I have a firm understanding of OOP concepts. I am really interested in web development and would like to learn a programming language that can be used to build dynamic web applications. My question is what language should I learn? I've narrowed it down to python or ruby. Also, I want to learn a programming language that will help me get a job upon graduating. So essentially, I will use this particular language to build applications that will help me get a job in the future.

• Testing complex compositions

  - by phlipsy

  I have a rather large collection of classes which check and mutate a given data structure. They can be composed via the composition pattern into arbitrarily complex tree-like structures. The final product contains a lot of these composed structures. My question is now: How can I test those? Albeit it is easy to test every single unit of these compositions, it is rather expensive to test the whole compositions in the following sense: Testing the correct layout of the composition-tree results in a huge number of test cases Changes in the compositions result in a very laborious review of every single test case What is the general guideline here?

• Force Gnome 3 to work

  - by nkg5

  I have Ubuntu 12.10 on dual-boot with windows XP. My PC specifications are AMD Sempron 2800+ 1,6GHz with 512 MB ram and ATI Radeon 9250 graphic card with 128 MB memory. As Unity works slow and I don't like it's look, I installed gnome-shell. But as you know, Gnome 3 won't work on it. But gnome classic without effects works great. Thing is, when I turn off windows (by holding the power button or pressing restart button) my resolution on Linux is changed to 1024x768, and I can only change it by turning off the PC and turning off it's power source. But it is not the problem. The problem is that it runs Gnome 3 after one restart, it also runs better than Unity. My question is: Can I somehow force gnome 3 to work always and disable some of it's effects so it can run better?

• Multiple copies of JBoss acting as one? [migrated]

  - by scphantm

  I have a few ideas how to solve the problem, but one question about jboss clustering. Please, keep in mind these applications were written very poorly, that is why they require so much memory and there is nothing i can do about that right now. So, I have clustered applications on Jboss where the application was small enough to run on one box. Meaning that one machine could handle the load. But, the current problem is that i have been asked to run several systems on the same environment. Our machines are virtuals and due to limited hardware, are restricted to 8 GB RAM, which gives jboss about 7GB to itself. Unfortunately, that isn't enough to run the group of applications. Im constantly getting heap errors and crashes. If i cluster 2 or 3 jboss instances together, can i run applications that consume more resources than a single box can handle?

• Java and Eclipse setup properly, how do I install JOGL or LWJGL?

  - by shadowprotocol

  I have my Java environment installed alongside Eclipse, and I was successfully able to create and run a new project (simple System.out.println("Yay I work!"); I have the OpenGL SuperBible, and I primarily want to code 3D things (I'll take my time using the book to learn how to draw shapes in 3D space, etc..) Can you help me get setup with OpenGL in Java? I dont really need LWJGL, although I WILL make games eventually. I just can't even figure out with all of these terrible (and old) tutorials floating around on the net how to install either JOGL or LWJGL. If you can give me a hand with that, I'd appreciate it. I'd like to feel I contributed by having this page show the answer to the question, so that other poor souls googling for this same information can benefit.

• Why is n given the initial value of 1 in this loop?

  - by notypist

  From Kochan's "Programming in C": Input: printf ("TABLE OF TRIANGULAR NUMBERS\n\n"); printf (" n Sum from 1 to n\n"); printf ("--- ---------------\n"); triangularNumber = 0; for(n=1; n<=10; ++n){ triangularNumber += n; ? printf (" %i", n); } Output (only partly pasted): TABLE OF TRIANGULAR NUMBERS n = 1 Sum from 1 to n = 1 n = 2 Sum from 1 to n = 2 Question: I understand the purpose of this, but here's what I can't get my head around: If within the loop we assign an initial value of "1" to "n", then we check if n<=10, and if that's true (which it should be with the initial value), we then add "1" to n. Shouldn't (and I know it shouldn't, just don't understand why) the initial value displayed in our table be n=2 ? Thanks in advance for your patience and effort!

• Having problem to login after upgrading from 11.10 to 12.04

  - by LinuxIsMyFriend

  I just update to 12.04 from 11.10 and I get to the login screen w/o problems. When I enter my password the screen turns black and returns to the login screen half a second later. There is a related question out there which was solved by creating more space on the disk but my disks (or rather partitions) are all below 30%. I can log in as guest. I can also login at the cmd prompt (going to tty with Alt+Ctrl+F1) with my normal user credentials. When logged in as guest I can also install programs using my normal account password. There is the normal authentication error when I mistype my password so I'm also sure the password works. Any suggestions?

• MMORPG Server architecture: How to handle player input (messages/packets) while the server has to update many other things at the same time?

  - by Renann

  Yes, the question is is very difficult. This is more or less like what I'm thinking up to now: while(true) { if (hasMessage) { handleTheMessage(); } } But while I'm receiving the player's input, I also have objects that need to be updated or, of course, monsters walking (which need to have their locations updated on the game client everytime), among other things. What should I do? Make a thread to handle things that can't be stopped no matter what? Code an "else" in the infinity loop where I update the other things when I don't have player's input to handle? Or even: should I only update the things that at least one player can see? These are just suggestions... I'm really confused about it. If there's a book that covers these things, I'd like to know. It's not that important, but I'm using the Lidgren lib, C# and XNA to code both server and client. Thanks in advance.

I am open to learn new Programming Languages to develop the software for this barcode scanner. From which I see on our meeting. It uses Windows or Windows Mobile as OS. Can someone direct me to a tut site or just tell me what language I should use? Requirements is mostly, Log In, UI Entry of Details + Barcode, Process Button. Connection To SQL Server via Wifi Access Point to call the procedure afterwards. I am not developing a Barcode scanner, I am developing a UI Software like a Mobile App. I tried to google but I dont know what exact keywords I should search for. My question is, what PL is mostly used to develop this kind of softwares.

• I want to begin in this world, where can i meet information,help and people to start? [on hold]

  - by SYNOXYS

  So like the question says, I really want to begin to create something,or help creating something. I mess around with some 2d and 3d softwares like unity,gamemaker,UE... and tried to modelate (maya,3dmax),I use them a little,nothing professional, but all i've got is the sensation that i can't go really far. I feel like i am learning really slow, even having the will and some basics knows. But I want to change that, i want to really learn, to progress. I think that a good idea is meeting people like me, and start a non-commercial project or something. Thanks for your time,really. Greetings, SYNOXYS.

• How can I defend Ruby on Rails against customers' not technical opinion?

  - by okeen

  My customer, a translations business owner, just told me that he has been reading about Ruby on Rails and told me that "there are more PHP guys around there" and "it seems the community prefers it". What would you, as software engineer and freelancer, say to the customer to achieve these goals: Sell Make him see that the technology is my expert decision and Rails is as good or better than PHP (+ whatever framework) for this particular project. UPDATE: Thank you all for the suggestions! Tomorrow I've got another meeting with him, let's see how it goes, I will update again :) UPDATE 2: Finally I told him to read this thread and the result has been fantastic: He gave me the project and we are going to start right now. Thank you all for the help, you have free beer in my charge if we see someday :) BTW: I learned the lesson: be as transparent as possible, because if you believe in yourself and your work, there is no question compromising enough to beat you. regards

• Architecture driven by users, or by actions/content?

  - by hugerth

  I have a question about designing MVC app architecture. Let's say our application has three main categories of views (items of type 1, items of type 2...). And we have three (or more in future) types of users - Admins, let's say Moderators and typical Users. And in the future there might be more of them. Admins have full access to app, Moderators can visit only 2/3 type of items, and Users can visit only basic type of items. Should I divide my controllers/views/whatever like this: Items "A", Items "B", Items "C", then make them 100% finished and at the end add access privileges? Pros: DRY option Cons Conditional expressions in views Or another options: Items "A" / Admin, Items "A" / Moderator / Items "B" Admin ...? Pros: Divided parts of application for specific user (is that pros?) Cons: A lot of repeated code I don't have great experience in planning such things so it would nice if you can give me some tips or links to learn something about it.

• Storing Projects on Google Drive (Cloud)

  - by JamesKraw

  I've started using Google Drive for my cloud needs and backing up pretty much everything. I've got the app installed so it auto-sync's all my content in most things. My question is this, I am currently coding for iOS (although this applies to any coding project) and am split on storing my project files on Google Drive while using sync. My theory is that if I did use it, I'd never have to worry about system crashes or lost code before backups, but if I do use it it will be sync'ing a-lot and I thought there might be problems with it detecting changes and trying to sync for example half way through compiling. Bandwidth isn't an issue as I have fast connection and unlimited monthly allowance. Has anyone ever used this, or similar cloud-based sync'ing (dropbox etc) for this and knows whether it works or not or whether there are any potential problems etc.

• Ubuntu server upgrade 11.04 to 11.10 fails

  - by DLosc

  I'm actually trying to upgrade my Ubuntu 11.04 server to 12.04, but I have to go through 11.10 first, right? Well, do-release-upgrade is failing miserably. Here are some representative screenshots: Screenshot 1 Screenshot 2 Screenshot 3 Screenshot 4 And finally... Yeah. I found this question, which appears to have similar errors, but I've tried all of the suggestions given there and nothing has changed. I tried running apt-get dist-upgrade; it churned for a while and eventually came back with "Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?" Ran apt-get update and got much the same kinds of error messages I got from do-release-upgrade. Any ideas/suggestions/solutions? Should I try downloading & upgrading from the CD instead? I'm glad to provide any further information I've forgotten.

• Do teams get more productive by adding more developers? [duplicate]

  - by jgauffin

  This question already has an answer here: Why does adding more resource to a late project make it later? 12 answers Suppose you've got a project that is running late. Is there any proof or argument that teams become much more productive by adding more people? I am looking for answers that can be supported by facts and references if possible. What I'm thinking about is that existing devs have to teach the new ones (thus losing overall development time), and then the new developers have to study the code (and tasks) before they can become fully productive.

• Why would companies allow these practices?

  - by MuduM

  Here's a situation that usually happens in some companies: Announce interesting product X. Promise a release date. Release on the promised released date, ready or not. Users discover and report defects. Send patch after patch after patch after patch after patch. My question is: Ummm, what could be the factors that would lead them to tolerate these undesirable practices? So, in the name of quality, what can be practically and realistically improved in those practicies? I can think of time constraints, user feedback, sponsors pressuring the company, lack of money.

• Managing shots of the player

  - by Bitbridge

  I'm currently developing a 2D Jump'n'Run and the situation is the following: The player has different weapons he can collect and is then able to shoot the weapon's projectiles (laser, rockets, whatever). In my previous game (space shooter) I just had a manager class for all the weapon-shots, it stored them in a container and then updates and draws every single one. When the "shoot-event" occurred, the "ProjectileManager" was notified and it added the wanted projectile. The input for player action is handled in the player-class, so the player would have to know the manager to call the function of the manager. I also have a collisionManager, that checks for collisions between, for example, enemies and the projectiles and then notifies these objects. However, I somehow have the feeling, that I shouldn't use this approach and that there might be a better way to handle this. I know, the question is a bit vague, I'm pretty much just looking for input and ideas to improve my design.

• Vector transform equation explanation

  - by cyberdemon

  I'm trying to understand the maths of moving points in a 3d space by making a game written in C#. I'm looking at this wolfire blog series which explains some basic 3d maths. I've read the first two parts but am stuck on the 3rd. I know it's all really rudimentary stuff but I find Googling for help with equations really hard. The one I'm struggling with is: 0*(0.66,0.75) + 2*(-0.75, 0.66) = (-1.5, 1.3) How can anything multiplied by 0 not be 0? So my question is how does this look in code: x(a,b) + y(c,d) I know it's basic stuff but I just can't see it.
