• 3D space game development

  - by user1693061

  I want to develop a 3D game (sci-fi type with spaceships) which can be played on multiplayer mode and by multiplayer i mean around 10 players for start as it will be a personal testing project and mostly educational. I have been searching for some days about the available languages and engines but i am kinda confused. Since i have been learning Java for my 1st year in I.T university and i have pretty good understanding i thought i would go with the Java language and develop that game on an applet so it could be played on a browser. After going through an applet game tutorial i understood how graphics work on an applet. So.. 1st question: Could an applet carry the burden of a 3D game especially on multiplayer? My thinking: It's a space game so the graphics should not be such a big problem since it wont be that crowded with entities apart from ships, planets and some effects. If the java applet is not the way for my project i would't mind "developing it on desktop"(i mean not making it a browser game). 2nd question: Should i use Unity engine for my purpose(space game)? If not name other language/engine combo.

• Creating a 2D Line Branch

  - by Danran

  I'm looking into creating a 2D line branch, something for a "lightning effect". I did ask this question before on creating a "lightning effect" (mainly though referring to the process of the glow & after effects the lightning has & to whether it was a good method to use or not); Methods of Creating a "Lightning" effect in 2D However i never did get around to getting it working. So i've been trying today to get a seconded attempt going but i'm getting now-were :/. So to be clear on what i'm trying to-do, in this article posted; http://drilian.com/2009/02/25/lightning-bolts/ I'm trying to create the line segments seen in the images on the site. I'm confused mainly by this line in the pseudo code; // Offset the midpoint by a random amount along the normal. midPoint += Perpendicular(Normalize(endPoint-startPoint))*RandomFloat(-offsetAmount,offsetAmount); If someone could explain this to me it would be really grateful :).

• Modular Web App Network Architecture

  - by nairware

  Assuming that I am dealing with dedicated physical servers or VPSs, is it conceivable and does it make sense to have distinct servers setup with the following roles to host a web application? Reverse Proxy Web server Application server Database server Specific points of interest: I am confused how to even separate the web and application servers. My understanding was that such 3-tier architectures were feasible. It is unclear to me if the app server would reside directly between the web and database server, or if the web server could directly interact with the database as well. The app server could either do the computational heavy-lifting on behalf of the app server or it could do heavy-lifting plus control all of the business logic (as implied in the diagram above, thus denying the web server of direct database access). I am also unsure what role the reverse proxy (ex. nginx) could and should fulfill as a web server, given the above mentioned setup. I know that nginx has web server features. But I do not know if it makes sense to have the reverse proxy be its own VPS, given that the web server–in theory–would be separate from the app server.

• tdd is about design not verification what does it concretely mean?

  - by sigo

  I've been wondering about this. What do we exactly mean by design and verification. Should I just apply tdd to make sure my code is SOLID and not check is correct external behaviour ? Should I use Bdd for the correct behaviour part ? Where I get confused also is regarding TDD code katas, to me they looked like more about verification than design... shouldn't they be called bdd katas instead of tdd katas? I reckon that for example uncle bob bowling kata leads in the end to a simple and nice internal design but I felt that most of the process was more around vérification than design. Design seemed to be a side effect of testing incrementally the external behaviour. I didnt feel so much that we were focusing most of our efforts on design but more on vérification. While normally we are told the contrary, that in TDD, verification is a side effect, design is the main purpose. So my question is what should i focus exactly on when i do tdd: SOLID, external Api usability, what else...? And how can I do that without being focused on verification ? What do you guys focus your energy on when you are practicing TDD ?

• setting up freedns with an existing domain

  - by romeovs

  I've been running a webserver off of a pc at a static IP succesfully for the past 5 months. recently however, I've moved into another appartment and my ISP only provides a dynamic IP (my IP changes from time to time). I'm not an internet genius but I was thinking to fix this by using a Dynamic DNS provider. So I got on the web and found freedns. I'm a bit confused about how to set up everything though. I've managed to succesfully install the IP updater daemon on my web server. Then, in my registrars control panel, I set the NS records to point at ns1 through ns4.afraid.org (removing the old NS records). I'm not certain what I should do with the A records though (for now they are still pointing to the old static IP address). I have A records for www, blog, irc, etc. but I cannot point them at my new IP address, because it isn't Could someone explain this in the clearest possible sense (perhaps elaborating on what happens at each step of the DNS process). I never really knew what the A records are for anyway. (note that I haven't really found any documentation at the freedns website, or on google)

• How to collaborate on features using github

  - by Robert Dailey

  github encourages 1 fork per user, so that that user can work independently on a feature and then request that feature to be accepted into the main repository via pull request. However, what if 2 developers need to collaborate on that feature? What is the ideal workflow for this? I could see a number of options: Both developers fork the original repository. Each developer pulls/pushes changes between each other's repository. This seems like a lot of work (tiny micro operations) and also creates a delay between changes, so increases the window for conflicts. Developer 1 forks from the main repository, developer 2 forks from developer 1. Same as #1 mainly but hopefully simplifies Developer 2's life a little? Developer 1 gives Developer 2 permissions to his own fork, so they both work out of the same central repository. Not sure if this is ideal. I'm also curious where branches come into this. Obviously there would be a branch for the feature itself but that branch can't exist in a single place, it would have to exist on multiple forks and be synchronized. Basically just really confused about this workflow, would like an approach for how this can be best accomplished.

• How system services are started in 12.10?

  - by Salem

  One thing that always confused me in Ubuntu was how system services are started. I know that Ubuntu uses Upstart and supports SysV, but which one is used to start the services? This matters when you want a "manual" start for a service. For example, on my system i have files for the following services either in /etc/init.d/<service> (Upstart) and /etc/init/<service>.conf (SysV): acpid, mysql, networking, qemu-kvm, ufw, libvirt-bin So if i want to disable MySQL execution at startup, i must use the Upstart way or the SysV way to disable it? Also, how can i tell which of those is really used to start a generic service? Edit The really doubt here is not how disable/enable services using SysV/Upstart. What really confuses me is that some services seem to be defined (and enabled) in SysV and Upstart at the same time. Is there any precedence between them (like if mysql is enabled in both launch it using SysV)? Or can it be the case that one tool uses the other in background?

• Python Web Applications: What is the way and the method to handle Registrations, Login-Logouts and Cookies? [on hold]

  - by Phil

  I am working on a simple Python web application for learning purposes. I have chosen a very minimalistic and simple framework. I have done a significant amount of research but I couldn't find a source clearly explaining what I need, which is as follows: I would like to learn more about: User registration User Log-ins User Log-outs User auto-logins I have successfully handled items 1 and 3 due to their simple nature. However, I am confused with item 2 (log-ins) and item 4 (auto-logins). When a user enters username and password, and after hashing with salts and matching it in the DB; What information should I store in the cookies in order to keep the user logged in during the session? Do I keep username+password but encrypt them? Both or just password? Do I keep username and a generated key matching their password? If I want the user to be able to auto-login (when they leave and come back to the web page), what information then is kept in the cookies? I don't want to use modules or libraries that handle these things automatically. I want to learn basics and why something is the way it is. I would also like to point out that I do not mind reading anything you might offer on the topic that explains hows and whys. Possibly with algorithm diagrams to show the process. Some information: I know about setting headers, cookies, encryption (up to some level, obviously not an expert!), request objects, SQLAlchemy etc. I don't want any data kept in a single web application server's store. I want multiple app-servers to be handle a user, and whatever needs to be kept on the server to be done with a Postgres/MySQL via SQLAlchemy (I think, this is called stateless?) Thank you.

• Trouble with speed and vectors

  - by Eegabooga

  I'm working on adding bullets to my game. Right now I can shoot bullets in the direction that I would like from a ship by getting the ship's angle: int speed = 5; int dx = -(cos(degreesToRadians(ship.angle)) * speed); // rate of change in the x direction int dy = -(sin(degreesToRadians(ship.angle)) * speed); // rate of change in the y direction bulletPosition.addX(dx); // addX(dx) is simply bulletPosition.x += dx bulletPosition.addY(dy); The ship is pretty much the exact same thing, except I use the += operator: int dx += -(cos(degreesToRadians(angle)) * 0.15) int dy += -(sin(degreesToRadians(angle)) * 0.15); shipPosition.addX(dx); shipPosition.addY(dy); I would like to be able to add the ship's velocity to the bullet's velocity, but I'm a little confused as to how should get the speed from the ship's vector. I thought that adding the ship's dx to the bullet's dx like int dx = -(cos(degreesToRadians(ship.angle)) * speed * dx) would work because I'm adding the rate of change of the ship to the rate of change of the bullet, but that doesn't work. So here's the final question: How can I get the speed of my ship and apply it to my bullet's speed? Thanks in advance for all help :)

• Checking for collisions on a 3D heightmap

  - by Piku

  I have a 3D heightmap drawn using OpenGL (which isn't important). It's represented by a 2D array of height data. To draw this I go through the array using each point as a vertex. Three vertices are wound together to form a triangle, two triangles to make a quad. To stop the whole mesh being tiny I scale this by a certain amount called 'gridsize'. This produces a fairly nice and lumpy, angular terrain kind of similar to something you'd see in old Atari/Amiga or DOS '3D' games (think Virus/Zarch on the Atari ST). I'm now trying to work out how to do collision with the terrain, testing to see if the player is about to collide with a piece of scenery sticking upwards or fall into a hole. At the moment I am simply dividing the player's co-ordinates by the gridsize to find which vertex the player is on top of and it works well when the player is exactly over the corner of a triangle piece of terrain. However... How can I make it more accurate for the bits between the vertices? I get confused since they don't exist in my heightmap data, they're a product of the GPU trying to draw a triangle between three points. I can calculate the height of the point closest to the player, but not the space between them. I.e if the player is hovering over the centre of one of these 'quads', rather than over the corner vertex of one, how do I work out the height of the terrain below them? Later on I may want the player to slide down the slopes in the terrain.

• Ubuntu 12.04 Network Manager: unable to save manual setting to set up a static ip

  - by Andy

  I am fairly familiar with setting up servers, and ubuntu is generally my flavor of choice, but I just installed 12.04 desktop and I am seeing some behavior in network manager that is really puzzling. The network connection works fine if I leave it set on dhcp, but I would like a static IP address for my new web server. When I go into network manager and edit the connection for the one and only NIC I can select MANUAL from the dropdown menu but as soon as I do the Save button becomes greyed out. Even after filling out all fields for the connection it is still grey and I am unable to save the static IP connection information. Any thoughts would be greatly appreciated. I'm hoping there is just some new setting that I am unaware of.... On another note, if I stop the network manager and go edit the interfaces file (and the appropriate hosts/routes/dns files), I do get a static ip address assigned and I can contact my server from the outside, however, the server cannot find the internet. Can't ping even its own ip... I can ping the loopback interface though. I'm really confused on this one. Hoping someone can offer some help.

• Want Google to index redirect urls

  - by Dave Goten

  I'm having issues with users who think that Google Search is the address bar. Some of the sites that link to my site use user friendly addresses with 301 redirects to pages that have less friendly URLs. So, for example if I enter www.foo.com/bar it goes to www.bar.com/page.php?some-parameters-and-utm-codes-etc usually this is done by a 301 redirect in order to keep the SEO from foo.com on bar.com and so on, which I believe is standard practice. However, lately there have been more and more people searching www.foo.com/bar instead of going to www.foo.com/bar directly and because the page /bar is nothing more than a redirect it has no SEO that I know of. Things I've thought of but haven't been able to test, because Google takes forever to update :) (and I'm lazy like that), include using Google sitemaps and having them enter their redirects as entries there. (I could see this working if they were the top search entry all the time, and it might appear as a sitelink, but I don't know if that'll make the url itself show up in searches) Using Canonical tags on my pages to the redirects they set up. Which is a nightmare in itself because of the nature of my pages. One week the www.foo.com/bar might go to www.bar.com/pageA.php the next it might goto www.bar.com/pageB.php and having to remember to take the canonical tag off of pageA, so that it doesn't get confused with pageB would be a pain. Using 302 redirects -.- So I guess the question here is, does anyone have any experience or knowledge about this? What should I do to make www.foo.com/bar show up when someone 'searches' for this redirect url?

• Should I use OpenGL or DX11 for my game?

  - by Sundareswaran Senthilvel

  I'm planning to write a game from scratch (a BIG Game, for commercial purpose). I'm aware that there are certain compute libraries like OpenCL, AMD APP SDK, C++ AMP as well as DirectCompute - both from MS (NOT interested in CUDA) are available in the market. I'm planning to write the game from the scratch, which includes the following engines... Physics Engine AI Engine Main Game Engine (... and if anything is missed). I'm aware that, there are some free physics engine libraries in the market. Not sure about free AI engine libraries. I'm bit confused in choosing between the OpenCL, AMD APP SDK, and C++ AMP libraries (as already mentioned i'm NOT interested in CUDA). I want my game to be published in Windows/Android/Mac OSX. It means it should be a cross-platform game. I will be having "one source code" that i'll compile for various platforms like Windows/Android/Mac OSX, and any others if i missed. Note: Since I'm NOT a Java guy, kindly do NOT suggest me the Java Language. For Graphics language should i use OpenGL or DirectX 11? I have heard that OpenGL runs on a single core, and not sure of DirectX 11. Between OpenGL and DirectX which one should i follow? or else, are there any other graphics language that i need to start with? I want to make use of the parallelism in GPU as well as CPU.

• Booting to a windows recovery partition from GRUB

  - by Andy Groff

  This should be simple but I cannot figure out how to do it. I've been dual booting ubuntu and vista for a while. About 8 months ago, I realized my windows partition got corrupt and does not boot. This wasn't a problem since I didn't need it anyways, but now I do need windows. Using the disk manager I can see a partition called Toshiba System Volume which is 1.6 GB and one called HDD Recovery which is 7.8 GB. I assume the second one is what I need and i'm not sure what the first one is for. Anyways, how do I boot to this one? Is it a matter of configuring GRUB to boot to it? Once I do boot to it will it let me only reformat my windows partition, or is it going to restore the entire hard drive to factory condition? I assume I'll get the general windows installer which lets me choose the partition but, as you can probably tell, I've never used a recover partition. Should I burn the contents of the partition to a disk and boot to that? Sorry if this is obvious but I'm confused and cannot figure this out.

• Software Manager who makes developers do Project Management

  - by hdman

  I'm a software developer working in an embedded systems company. We have a Project Manager, who takes care of the overall project schedule (including electrical, quality, software and manufacturing) hence his software schedule is very brief. We also have a Software Manager, who's my boss. He makes me write and maintain the software schedule, design documents (high and low level design), SRS, change management, verification plans and reports, release management, reviews, and ofcourse the software. We only have one Test Engineer for the whole software team (10 members), and at any given time, there are a couple of projects going on. I'm spending 80% of my time making these documents. My boss comes from a Process background, and believes what we need is better documentation to improve software: (1) He considers the design to be paramount, coding is "just writing the design down", it shouldn't take too long, and "all the code should be written before the hardware is ready". (2) Doesn't understand the difference between a Central & Distributed Version control, even after we told him its easier to collaborate with a distributed model. (3) Doesn't understand code, and wants to understand every bug and its proposed solution. (4) Believes verification should be done by developer, and validation by the Tester. Thing is though, our verification only checks if implementation is correct (we don't write unit tests, its never considered in the schedule), and validation is black box testing, so the units tests are missing. I'm really confused. (1) Am I responsible for maintaining all these documents? It makes me feel like I'm doing the Software Project Management, in essence. (2) I don't really like creating documents, I want to solve problems and write code. In my experience, creating design documents only helps to an extent, its never the solution to better or faster code. (3) I feel the boss doesn't really care about making better products, but only about being a good manager in the eyes of the management. What can I do?

• How does this circle collision detection math work?

  - by Griffin

  I'm going through the wildbunny blog to learn about collision detection. I'm confused about how the vectors he's talking about come into play. Here's the part that confuses me: p = ||A-B|| – (r1+r2) The two spheres are penetrating by distance p. We would also like the penetration vector so that we can correct the penetration once we discover it. This is the vector that moves both circles to the point where they just touch, correcting the penetration. Importantly it is not only just a vector that does this, it is the only vector which corrects the penetration by moving the minimum amount. This is important because we only want to correct the error, not introduce more by moving too much when we correct, or too little. N = (A-B) / ||A-B|| P = N*p Here we have calculated the normalised vector N between the two centres and the penetration vector P by multiplying our unit direction by the penetration distance. I understand that p is the distance by which the circles penetrate, but I don't get what exactly N and P are. It seems to me N is just the coordinates of the 3rd point of the right trianlge formed by point A and B (A-B) then being divided by the hypotenuse of that triangle or distance between A and B (||A-B||). What's the significance of this? Also, what is the penetration vector used for? It seems to me like a movement that one of the circles would perform to get un-penetrated.

• 12.10 Wireless networking

• How far should one take e-mail address validation?

  - by Mike Tomasello

  I'm wondering how far people should take the validation of e-mail address. My field is primarily web-development, but this applies anywhere. I've seen a few approaches: simply checking if there is an "@" present, which is dead simply but of course not that reliable. a more complex regex test for standard e-mail formats a full regex against RFC 2822 - the problem with this is that often an e-mail address might be valid but it is probably not what the user meant DNS validation SMTP validation As many people might know (but many don't), e-mail addresses can have a lot of strange variation that most people don't usually consider (see RFC 2822 3.4.1), but you have to think about the goals of your validation: are you simply trying to ensure that an e-mail address can be sent to an address, or that it is what the user probably meant to put in (which is unlikely in a lot of the more obscure cases of otherwise 'valid' addresses). An option I've considered is simply giving a warning with a more esoteric address but still allowing the request to go through, but this does add more complexity to a form and most users are likely to be confused. While DNS validation / SMTP validation seem like no-brainers, I foresee problems where the DNS server/SMTP server is temporarily down and a user is unable to register somewhere, or the user's SMTP server doesn't support the required features. How might some experienced developers out here handle this? Are there any other approaches than the ones I've listed? Edit: I completely forgot the most obvious of all, sending a confirmation e-mail! Thanks to answerers for pointing that one out. Yes, this one is pretty foolproof, but it does require extra hassle on the part of everyone involved. The user has to fetch some e-mail, and the developer needs to remember user data before they're even confirmed as valid.

• Should I be learning Linq, Direct SQL Commands (in .net), EF or other?

  - by Wil

  Basically, I have a very good knowledge of plain old SQL coming from Classic ASP programming. Over the past couple of months, I have been learning C# and today was my first full day at MVC 3 (Razor) which I am loving! I need to get back in to Databases and I know that writing SqlCommand everywhere is obviously outdated (although it is nice I can still do it!). I used to go to a great usergroup as an IT Pro and the developer stuff went completely over my head, however I do remember a few things which kept coming up such as LINQ... However, that was some time ago and now the same people on Twitter are saying how out dated it is. I have tried to do research on both and I am clueless as to what direction I should go in, or when to use one over another (if learning both is a good thing). I am more so confused as I thought EF was a part of the .Net Framework, however, reading through the quick start guide, I had to download a component using Nuget. ... Basically I am out of my depth here and just need some honest advice of where to go!

• Unity elements sometimes appear while full screen in Virtualbox - how to stop it?

  - by frumbert

  Launcher is great, and it helps me finds stuff. I have the latest release of 12. But when I'm full screen in VirtualBox running another operating system and I hit some key combination I haven't yet figured out, Unity suddenly grabs keyboard focus. It might be alt-tab, it might be left-control x. I have physically pulled both the windows key and FN key off my laptop because they get in the way, so it's probably not the windows key. You don't know the focus has been stolen because the full screen app (VirtualBox) is still full screen and the Unity element is in the background. But you're busy typing into a Unity box, not your foreground application. This is particularly annoying. In my screenshot (taken from a camera, because the built in screen capture program can't capture a screenshot containing the launcher...) the windows VM is the foreground application, but the "Run Command" entry box has come up and is capturing the keyboard: I would like a foreground full screen app to stay that way. Is there a way that I can keep Unity but only have it activate its elements (e.g. pop out with its search box) if I physically click a button, not type some random key combination that foreground applications can get confused about? Otherwise I can do without the launcher or other elements, because doing my actual work is more involved than just launching programs.

• How to implement behavior in a component-based game architecture?

  - by ghostonline

  I am starting to implement player and enemy AI in a game, but I am confused about how to best implement this in a component-based game architecture. Say I have a following player character that can be stationary, running and swinging a sword. A player can transit to the swing sword state from both the stationary and running state, but then the swing must be completed before the player can resume standing or running around. During the swing, the player cannot walk around. As I see it, I have two implementation approaches: Create a single AI-component containing all player logic (either decoupled from the actual component or embedded as a PlayerAIComponent). I can easily how to enforce the state restrictions without creating coupling between individual components making up the player entity. However, the AI-component cannot be broken up. If I have, for example, an enemy that can only stand and walk around or only walks around and occasionally swing a sword, I have to create new AI-components. Break the behavior up in components, each identifying a specific state. I then get a StandComponent, WalkComponent and SwingComponent. To enforce the transition rules, I have to couple each component. SwingComponent must disable StandComponent and WalkComponent for the duration of the swing. When I have an enemy that only stands around, swinging a sword occasionally, I have to make sure SwingComponent only disables WalkComponent if it is present. Although this allows for better mix-and-matching components, it can lead to a maintainability nightmare as each time a dependency is added, the existing components must be updated to play nicely with the new requirements the dependency places on the character. The ideal situation would be that a designer can build new enemies/players by dragging components into a container, without having to touch a single line of engine or script code. Although I am not sure script coding can be avoided, I want to keep it as simple as possible. Summing it all up: Should I lob all AI logic into one component or break up each logic state into separate components to create entity variants more easily?

• When NOT to use a framework

  - by Chris

  Today, one can find a framework for just about any language, to suit just about any project. Most modern frameworks are fairly robust (generally speaking), with hour upon hour of testing, peer reviewed code, and great extensibility. However, I think there is a downside to ANY framework in that programmers, as a community, may become so reliant upon their chosen frameworks that they no longer understand the underlying workings, or in the case of newer programmers, never learn the underlying workings to begin with. It is easy to become specialized to a degree that you are no longer a 'PHP programmer' (for example), but a "Drupal programmer", to the exclusion of anything else. Who cares, right? We have the framework! We don't need to know how to "do it by hand"! Right? The result of this loss of basic skills (sometimes to the extent that programmers who don't use frameworks are viewed as "outdated") is that it becomes common practice to use a framework where it is not required or appropriate. The features the framework facilitates wind up confused with what the base language is capable of. Developers start using frameworks to accomplish even the most basic of tasks, so that what once was considered a rudimentary process now involves large libraries with their own quirks, bugs, and dependencies. What was once accomplished in 20 lines is now accomplished by including a 20,000 line framework AND writing 20 lines to use the framework. Conversely, one does not want to reinvent the wheel. If I'm writing code to accomplish some basic, common little task, I might feel like I am wasting my time when I know that framework XYZ offers all the features I am after, and a whole lot more. The "whole lot more" part still has me worried, but it doesn't seem that many even consider it anymore. There has to be a good metric to determine when it is appropriate to use a framework. What do you consider the threshold to be, how do you decide when to use a framework, or, when not.

• How do I bridge my wireless to my wired connection?

  - by gatoatigrado

  I want to bridge the wireless connection with the wired connection. The wireless is the host and the wired is the client, so to speak. Internet sharing (inet <--> wifi <--> ethernet) I tried to bridge my ethernet connection by going to network manager edit connections wired edit IPv4 settings shared to other computers Screenshots However, it seems to automatically disconnect half a second after it says "connection established"! edit 2 got the network manager logs, it seems the address is in use. See http://pastebin.com/DjqRshxW , line 45. nm-tool output is here: http://pastebin.com/x5Aci5V1 . I tried firestarter, as mentioned in another thread, and no luck. I don't have time to bother with a dozen command line tricks, unless is copy & pasting a shell script... so please suggest ways that use GUIs and/or won't leave my computer in a confused state (e.g. disabling network manager, manually connecting to a WPA network, installing brutils, etc.). edit: one idea that would work, if it's possible -- is there a way to share connections via SSH and SOCKS5? I'd need to do this at a system-wide level though; I only know how to do it through the browser now. Then, I could run ifconfig eth0 192.168.4.1 on the computer sharing the inet, and ifconfig eth0 192.168.4.2 on the computer I'm trying to share with; I know this does work for host-to-host transfers. edit 3 If I run sudo killall dnsmasq, then nothing is using the 10.42.43.1 address the network manager sharing wants to use. But now it just takes longer to die, with error "NetworkManager[5935]: dnsmasq died with signal 9" [ http://pastebin.com/4FNtpugi ]. Looking at just the commands [ http://pastebin.com/1vrtQeWk ], maybe it's trying to route eth0 to itself? I'm not that familiar with networking things though.
