• How are dependant quests generated in Guild Wars 2?

  - by Aufziehvogel

  I recently read that Guild Wars 2 uses a system where the creation of quests depends on which actions user took when they were presented another quest. An example was: There might be a quest to protect a person. If users do not take this action, the person might be kidnapped and later there is a quest to rescue this person. Is there any information on whether the creation of these quests is somehow automatic? From the article it sounded like automatically, but from the specific example you could also guess that people just created a task-set where they added conditions (Task 1 taken: OK; Task 1 not taken: Show Task 2). From what I heard about AI they might also have implemented some sort of a huge neural network to make decisions?

• Getting weather information (from a thermometer and a hygrometer)

  - by EKS

  I have decided, as a arrogant geek, to build my own home ventilation and heating system, and will try to do this as my little project. I have always been annoyed with the lack of good ventilation systems at work, so I accept building my own is arrogant. Does anyone know about a device I can interact with that allows me to get temperature and humidity that I can interact with using C#? I cannot get it from the Internet because I need to get the humidity from my server "room", so I can control the dehumidifier there. Similar with temperature, outside is not that important. It would be a huge plus if the sensors had some sort of wireless access.

• "more than 3 levels of indentation, you're screwed" How should I understand this quote ?

  - by jokoon

  The answer to that is that if you need more than 3 levels of indentation, you're screwed anyway, and should fix your program. What can I deduct from this quote ? On top of the fact that too long methods are hard to maintain, are they hard or impossible to optimize for the compiler ? I don't really understand if this quote encourages better coding practice or is really a mathematical/algorithmic sort of truth... I also read in some C++ optimizing guide that dividing up a program into more function improves its design is a common thing taught at school, but it should be not done too much, since it can turn into a lot of JMP calls (even if the compiler can inline some methods by itself).

• Sending Mass Emails

  - by Larry Anderson

  I have a massive list of users who registered for accounts and opted into a mailing list on my web site and I am interested in sending out a weekly newsletter. How should I go about doing this. I tried sending it out through my host server, but I received a notice stating that if I did it again they would kick me off the server. Are there any good companies that are designed for this type of thing? I need to find a company that will support this and show me some sort of report about how many emails get opened, deleted, opened then deleted, etc. Any recommendations?

• Creating a interactive grid for puzzle game

  - by Noupoi

  I am trying to make a slitherlink game, and am not too sure how to approach creating the game, more specifically the grid structure on which the puzzle will be played on. This is what a empty and completed slitherlink grid would look like. The numbers in the squares are sort of clues and the areas between the dots need to be clickable. http://i.stack.imgur.com/U1kXn.gif http://i.stack.imgur.com/RMwiv.gif I would like to create the game in VB .NET. What data structures should I try to use, and would it be beneficial using any frameworks such as XNA?

• Issues with external mounting after pysdm removed

  - by K. R. Huard

  So, I'm very new to ubuntu. I was having troubles getting my external hard drive to be read/write permission. It's owner is my macbook, and writing on the drive was repeatedly denied. In trying to sort this out, I tried the Nautilus commands (no success), installed the PYSDM application, changed some things (as suggested by this user in this forum http://askubuntu.com/a/113992 )but then found that I was getting an error message whenever I tried to mount an external storage device. The error is: Unable to mount DERPSTICK error mounting: mount exited with exit code 1: helper failed with: [mntent]: line 14 in etc/fstab is bad mount: only root can mount /dev/sdc1/ on /media/sdc1 Others with similar problems put their fstab up here, but I'm not sure how to bring it up, or if I should even try. Thanks for your time!

• When do you say "near ID" / "far ID" when using RTMFP in ActionScript 3?

  - by Panzercrisis

  I've been using RTMFP streaming for around a year in ActionScript 3, and I pretty much know the difference between a near ID and far ID. The near ID is your peer ID, and the far ID is the other guy's peer ID. The problem I'm having is that, to my knowledge, choosing whether to use one term or the other in a given sentence is a little like choosing whether to say "go" or "come". In English, "go" and "come" have opposite meanings, but ironically, they can still be used almost interchangeably. It's because whether you're going or coming is so heavily dependent on perspective, as opposed to anything concrete. Is the choice of words between "near ID" and "far ID" just as ambiguous, or is there some sort of method to the madness? Thanks!

• HP Bluetooth Mouse Connection Problems

  - by Arthur Upfield

  About a month ago, I turned on my laptop (Ubuntu 14.04 and Windows 8.1 dual boot, though the mouse works fine in Windows), logged in and connected my HP x4000b mouse via a bluetooth dongle (Kinivo BTD-400), and noticed that the battery indicator in Ubuntu said that the mouse battery was at 0%. The day before it was around 30%, so I decided to just change the batteries in the mouse, but after reconnecting with the new batteries, it still said 0%. The mouse connected and worked just fine, so I didn't think much of it. About a week after that, I noticed that my mouse would sometimes disconnect if I didn't use it, but since reconnecting isn't that hard I just decided to leave it. Now it also won't reconnect unless I log out and back in again, which is getting sort of tedious. Is there any way to fix this issue? Any help is appreciated, and I will try and respond to questions ASAP. Thanks.

• Games with user-supplied artifical intelligence (AI) engines?

  - by RoboShop

  I remember Microsoft used to have this AI game for the .NET framework which allowed you to program a species and this species could be introduced to an "ecosystem" full of species that other people had programmed and they could interact with each other, etc. I can't remember what it was called, but I remembered thinking it was a pretty good idea. Are there any other similiar sites like that, which allows you to design some sort of AI engine and pit it against other programmer's creations? It could be an ecosystem type thing, or it could be a card or board game.

• I just updated to 12.04 from 11.10 and now the Unity bar is very sluggish and even the menus do not show on the panel

  - by jredkai

  Like the title says, I just upgraded to 12.04, I know it is only beta but I'm having problems with the Unity bar and the panel with the menus. First the Unity bar is acting very sluggish..I really don't know how to explain it. Also with the menu at the top, it keeps a strange little black bar on everything, even across my tabs in Firefox, it also doesn't let me see any of the menus, well they flicker and you sort of have to guess where everything is. I'm at a loss, I've already ran updates a couple of times to see if I missed something. I really hope I don't have to completely redo my whole Ubuntu setup. Any help would be greatly appreciated.

• Installing package + dependancies and removing them all

  - by Sman789

  I currently use Xubuntu and was considering installing/trying GNOME Shell or Cinnamon by installing their respective metapackage. However, doing so would result in a massive number of dependencies being installed which would be almost impossible to remove individually at a later date if I decided I didn't like it. I wonder, therefore, if there is a way that I can track which packages Synaptic automatically downloads as part of the process and create a script of some sort to remove them all as well. I could then rest assured that if I don't like any of my new desktop environments, I can remove them in full without leaving a load of other applications and libraries lying around. Thankyou for any help! :)

• Any patent issue if I want to call my classes "signal/slot" as in Qt?

  - by user129506

  I need to code a signal-like mechanism and I was thinking of using the same "slot" and "signal" terms to indicate the signal and the function that needs to be called. Since this is a commercial application I'd like to know if there might be any issue with using these names, e.g. if Qt has some sort of patent on them (I searched around but couldn't find it). I believe this is a stupid question since patenting a class name would be moronic, to say the least.. but anyway... To add some detail: my code is ENTIRELY different and has NOTHING TO DO with Qt except the above. I don't use moc or any Qt class.

• The need for source control software - Team Foundation Server? or something different?

  - by l0Ft

  Recently, Here at the company, more than one programmer was appointed in charge for a LightSwitch(C#) software development project and immediately there was a need of some sort of source control/sync. We have never used Team Foundation Server but we'd gladly use it if it's worth it. Is it the right tool to use for synchronising code between programmers? Does it have the needed features? Do you have any other tool in mind? (I have used TortoiseSVN but it was too simple and 'texty' if you know what I mean, we need a professional tool) What other features does Team Foundation has that we can use? (if you did not understand any of the above please ask me to clarify further)

• Web Search for a Hard Drive

  - by zecougar

  Here is the situation. Our organization has a fair amount of data in the form of documents, images, videos stored on a intranet server. We need to be able to expose these documents via some sort of search functionality on the intranet. Provide some mechanism to organize and tag the documents on hard disk. Ideally we'd also like to provide a unified search across documents on the google apps for business instance that we have. Any ideas on how to approach this problem ?

• How can I acheive a smooth 2D lighting effect?

  - by Cyral

  I'm making a tile based game in XNA. So currently my lightning looks like this: How can I get it to look like this? Instead of each block having its own tint, it has a smooth overlay. I'm assuming some sort of shader, and to tell it the lighting and blur it some how. But im not an expert with shaders. My current lighting calculates the light, and then passes it to a spritebatch and draws with a color parameter. EDIT: No longer uses spritebatch tint, I was testing and now pass parameters to set the light values. But still looking for a way to smooth it.

• Structuring an input file

  - by Ricardo

  I am in the process of structuring a small program to perform some hydraulic analysis of pipe flow. As I am envisioning this, the program will read an input file, store the input parameters in a suitable way, operate on them and finally output results. I am struggling with how to structure the input file in a sane way; that is, in a way that a human can write it easily and a machine can parse it easily. A sample input file made available to me for a similar program is just a stream of comma-separated numbers that don't make much sense on their own, so that's the scenario I am trying to avoid. Though I am giving the details of my particular problem, I am more interested in general input-file structuring strategies. Is a stream of comma-separated values my best bet? Would I be better off using some sort of key:value structure? I don't know much about this, so any help will probably put me in a better track than I am now.

• Hardware question; booting ubuntu off of USB flash drive?

  - by Kon

  I'm currently running ubuntu off of a USB 3.0 flash drive on my laptop, and I have another USB 3.0 flash drive I use for storing larger files that I need to access and whatnot. But the issue is that both of the usb 3.0 flash drives don't fit next to each other at all, so I'm forced to use another usb 2.0 port located in a different spot on my laptop. Now my question is that if I use a USB 3.0 hub will that slow my connections down at all? or cause some sort of interference? Another question I had which I was unable to find anywhere on the internet is if there was a USB 3.0 hub with more than one upstream connection? Thanks for your time!

• Is KoboldTouch a good way to learn?

  Im thinking of buying a Cocos2D tutorial book called:Learn Cocos2d Game Development With Ios 5 I would buy it but it mentions something about KoboldTouch? Is this some sort of really simple way of coding a game? I wanna do it the best way possible to learn. What would be the best way? I love coding so I dont really want something to simplify the process unless its the best method. Any ideas? Thanks!

• Why is it good to split a program into multiple classes?

  - by user1276078

  I'm still a student in high school (entering 10th grade), and I have yet to take an actual computer course in school. Everything I've done so far is through books. Those books have taught me concepts such as inheritance, but how does splitting a program into multiple classes help? The books never told me. I'm asking this mainly because of a recent project. It's an arcade video game, sort of like a flash game as some people have said (although I have no idea what a flash game is). The thing is, it's only one class. It works perfectly fine (a little occasional lag however) with just one class. So, I'm just asking how splitting it into multiple classes would help it. This project was in JAVA and I am the only person working on it, for the record.

• Are these hacking attempts or something less sinister?

  - by Darkcat Studios

  I just had a look through our web server error logs, and Terminal services is reporting: "Remote session from client name a exceeded the maximum allowed failed logon attempts. The session was forcibly terminated." Hundreds of times, every 10.5 seconds or so for a period of about 5-10 minutes, once at 2pm yesterday and once again at about 1am this morning. We CURRENTLY have RDP open to the outside, as I am just completing the setup and now and then I/Others need to jump on from an outside office/location (VPN isn't an option) As these are so regular, am I right in assuming that they may be the result of some sort of dictionary attack? or could something like an internal admin's hung session cause such a mass of events? (Win Server 2008 R2)

• Dynamic Components

  - by Alex

  I am attempting to design a component-based architecture that allows Components to be dynamically enabled and disabled, much like the system employed by Unity3D. For example, all Components are implicitly enabled by default; however, if one desires to halt execution of code for a particular Component, one can disable it. Naively, I want to have a boolean flag in Component (which is an abstract class), and somehow serialize all method calls into strings, so that some sort of ComponentManager can check if a given Component is enabled/disabled before processing a method call on it. However, this is a pretty bad solution. I feel like I should employ some variation of the state paradigm, but I have yet to make progress. Any help would be greatly appreciated,

• Are there any actual examples of profitable programmer's "worker's cooperatives"?

  - by Wannabe Tycoon

  http://en.wikipedia.org/wiki/Worker_cooperative I'm curious whether there are, anywhere in the world, worker's cooperatives that center on a technology business that involves either programming, IT, or some sort of IT or programming related consulting or services. The wikipedia link above is an overview of the concept. The short form explanation is that a co-op is a worker-owned business. Also there is the notion that every worker owns shares in the business. I am interested in knowing whether an example of a "programmer's/IT co-op" even exists. Note: I am not talking about nor asking about a government-funded incubator nor any other socialized, state supported group. I also don't mean "co-working", which is renting an office with other self employed people doing their own thing. I mean a going, profitable IT business operating in a competitive environment that is worker-owned and run.

• /build folder used by PEAR

  - by Paul

  I've just noticed a root directory (/build) which I can't seem to find any information for. It looks like it's some sort of staging ground for PEAR (PHP). There are only two folders of different php versions in it, and each of those has a few PEAR tar files I've installed (via the PEAR command line). I'm really only asking this question because I find is strange PEAR (and only PEAR) would create its own root directory to store files. Is this normal? Does Ubuntu provide a /build directory for applications to use?
