  • How can I strip down Ubuntu?

    - by Thomas Owens
    I'm trying to fix what I consider a bloated install of Ubuntu. When I install Ubuntu on a machine, I get things that I don't want - web browsers, office applications, media players, accessibility utilities, Ubuntu One, and so on. My goal is to create a way that I can have an install of Ubuntu that contains only the most minimal packages - the administrative tools and package manager, a GUI (my preference would be GNOME), a text editor, core drivers (video cards, network cards - wired and wireless, input devices), and anything else that I have to have to run a stable distribution. From there, I would like to pick and choose which packages I install to create my own customized system. After playing around with other distros like Arch and Slackware, like how they provide a barebones install by default. However, I get trapped in a "configuration hell" - right now, I tried moving away from Ubuntu and to Arch, but after spending 6 hours with it, I still don't have a usable system. It's half configured and I don't have any usable software packages to enable me to work. Is anything that can help me available? Either something like the OpenSUSE builder that lets you choose applications and packages for the CD, an advanced installation mode where I can choose the packages to install and which to ignore, or a guide on how to strip Ubuntu down to its bare bones? And I suppose a natural follow up to this is once I have a stripped down Ubuntu, will this affect updating at all? When Canonical releases the next version of Ubuntu, I don't want any bloatware reinstalled. And yes, most of the applications that come with Ubuntu, I simply don't use. Ever.

  • Can windows XP be better than any Ubuntu (and Linux) distro for an old PC?

    - by Robert Vila
    The old laptop is a Toshiba 1800-100: CPU: Intel Celeron 800h Ram 128 MB (works ok) HDD: 15GB (works ok) Graphics adapter: Integrated 64-bit AGP graphics accelerator, BitBIT, 3D graphic acceleration, 8 MB Video RAM Only WindowsXP is installed, and works ok: it can be used, but it is slow (and hateful). I thought that I could improve performance (and its look) easily, since it is an old PC (drivers and everything known for years...) by installing a light Linux distro. So, I decided to install a light or customized Ubuntu distro, or Ubuntu/Debian derivative, but haven't been successful with any; not even booting LiveCDs: not even AntiX, not even Puppy. Lubuntu wiki says that it won't work because the last to releases need more ram (and some blogs say much more cpu -even core duo for new Lubuntu!-), let alone Xubuntu. The problems I have faced are: 1.There are thousands of pages talking about the same 10/15 lightweight distros, and saying more or less the same things, but NONE talks about a simple thing as to how should the RAM/swap-partition proportion be for this kind of installations. NONE! 2.Loading the LiveCD I have tried several different boot options (don't understand much about this and there's ALWAYS a line of explanation missing) and never receive error messages. Booting just stops at different stages but often seems to stop just when the X server is going to start. I am able to boot to command line. 3.I ignore whether the problem is ram size or a problem with the graphics driver (which surprises me because it is a well known brand and line of computers). So I don't know if doing a partition with a swap partition would help booting the LiveCD. 4.I would like to try the graphical interface with the LiveCD before installing. If doing the swap partition for this purpose would help. How can I do the partition? I tried to use Boot Rescue CD, but it advises me against continuing forward. I would appreciate any ideas as regards these questions. Thank you

  • Small-scale database options for .NET

    - by raney
    I have a .NET 4.0/WPF based application I've developed and maintain for my company that acts as a friendly GUI central-point-of-information, combining information pulled from a couple of SQL databases, as well as CSV exports from a few other applications. I would like to build out my own database to support the entirety of the information that the application accesses, so that I could have a service running on my server that would read in necessary remote SQL info and file exports, to provide the user's application with a single database to connect to, as well as to remove all of the file handling currently involved in the program (copying new CSV resources from network location, reading them into memory each launch.) I have complete control and flexibility here as long as the user's experience isn't affected, and this is as much a learning experience as it is tidying up. Caveat being, I don't have much in the way of a budget. Right now I recognize my options to be: SQL Express - I'm comfortable with the server setup, I like ADO.NET and LINQ to SQL. I feel that I have the least to learn here, but it would let me focus on SQL in a familiar environment. Perhaps in conjunction with Entity Framework? MongoDB - I don't know a whole lot about, but I've heard the name enough to make me curious. Brief research seems friendly enough, and there is .NET support. I like working with open source projects. My questions are: What's popular and extensible right now? I'm not far from starting to job-hunt, and I'd like this project to be relevant going forward. What am I missing? Pros, cons? Other options? What plays well with .NET? What are the things I should be considering, the questions I should be asking, when making a decision like this? Thanks for your time.

  • Integrating with Oracle Fusion Applications: Discovering Integration Artifacts

    - by Lionel Dubreuil
    Oracle Enterprise Repository serves as the core element to the Oracle SOA Governance solution. An industry-leading metadata repository, Oracle Enterprise Repository provides a solid foundation for delivering governance throughout the service-oriented architecture (SOA) lifecycle by acting as the single source of truth for information surrounding SOA assets and their dependencies. For Fusion Applications, the use of OER has been extended to include other integration asset types such as interface tables and other technical information such as data models, tables, views, lookups, profile options, et cetera. E-Business Suite users familiar with iRepository or eTRM will recognize the functionality in Fusion Applications OER. Oracle Enterprise Repository for Fusion Applications provides a common catalog of technical information, searchable using many different mechanisms. Customers can locate technical information by the name, description or keyword of the information they are looking for. They can also search by the type of asset they are trying to locate and/or where the asset sits in the product taxonomy. They can also see the how the asset dances in the choreography of some illustrative co-existence scenarios. These scenarios are laid out as both functional flow diagrams as well as technical interaction diagrams. Rajesh Raheja, software architect at Oracle, has recently posted an article on this topic: visibility and control are the key tenets to SOA governance, and the first step in integrating with Oracle Fusion Applications is to find out what are the integration options available. Oracle Enterprise Repository, an industry-leading metadata repository, provides this visibility. You can find his full blog post here.

  • Doing powerups in a component-based system

    - by deft_code
    I'm just starting really getting my head around component based design. I don't know what the "right" way to do this is. Here's the scenario. The player can equip a shield. The the shield is drawn as bubble around the player, it has a separate collision shape, and reduces the damage the player receives from area effects. How is such a shield architected in a component based game? Where I get confused is that the shield obviously has three components associated with it. Damage reduction / filtering A sprite A collider. To make it worse different shield variations could have even more behaviors, all of which could be components: boost player maximum health health regen projectile deflection etc Am I overthinking this? Should the shield just be a super component? I really think this is wrong answer. So if you think this is the way to go please explain. Should the shield be its own entity that tracks the location of the player? That might make it hard to implement the damage filtering. It also kinda blurs the lines between attached components and entities. Should the shield be a component that houses other components? I've never seen or heard of anything like this, but maybe it's common and I'm just not deep enough yet. Should the shield just be a set of components that get added to the player? Possibly with an extra component to manage the others, e.g. so they can all be removed as a group. (accidentally leave behind the damage reduction component, now that would be fun). Something else that's obvious to someone with more component experience?

  • How can I get multitouch enabled on my Sentelic touchpad (msi x350 notebook)?

    - by Jon
    I understand my MSI x350 notebook comes with a Sentelic trackpad, which supports multi-touch (according to the MSI website). Is there a way to enable multitouch on Ubuntu? I've been having difficulty finding info about this on google, and since it's not a synaptics touchpad I haven't been able to find much info in ubuntu docs. My mouse preferences doesn't have a trackpad tab like it does on, say, a Macbook. Running "xinput list" returns: FSPPS/2 Sentelic FingerSensingPad id=11 And in my Xorg.0.log: [ 17.481] (II) config/udev: Adding input device FSPPS/2 Sentelic FingerSensingPad (/dev/input/event6) [ 17.481] () FSPPS/2 Sentelic FingerSensingPad: Applying InputClass "evdev pointer catchall" [ 17.481] () FSPPS/2 Sentelic FingerSensingPad: always reports core events [ 17.481] () FSPPS/2 Sentelic FingerSensingPad: Device: "/dev/input/event6" [ 17.500] (II) FSPPS/2 Sentelic FingerSensingPad: Found 11 mouse buttons [ 17.500] (II) FSPPS/2 Sentelic FingerSensingPad: Found scroll wheel(s) [ 17.500] (II) FSPPS/2 Sentelic FingerSensingPad: Found relative axes [ 17.500] (II) FSPPS/2 Sentelic FingerSensingPad: Found x and y relative axes [ 17.500] (II) FSPPS/2 Sentelic FingerSensingPad: Configuring as mouse [ 17.500] () FSPPS/2 Sentelic FingerSensingPad: YAxisMapping: buttons 4 and 5 [ 17.500] (**) FSPPS/2 Sentelic FingerSensingPad: EmulateWheelButton: 4, EmulateWheelInertia: 10, EmulateWheelTimeout: 200 [ 17.500] (II) XINPUT: Adding extended input device "FSPPS/2 Sentelic FingerSensingPad" (type: MOUSE) [ 17.500] (II) FSPPS/2 Sentelic FingerSensingPad: initialized for relative axes.

  • What's a good Game development platform for a platformer game with these characteristics?

    - by Joe
    Yes, I know, the best way to make an indie game is to learn to code. I've got some scripting experience, but I want to do worldbuilding with already-existing tools (and communities surrounding those tools), and I've been really impressed with games like An Untitled Story that were made with pre-packaged toolsets at their core, like Game Maker. :) So I'm planning to make my game using either Game Maker or something like it. The basic parameters of my planned game: -2D platformer. -Physics/speed akin to Sonic the Hedgehog. -Large, non-linear world, flowing as seamlessly as possible -- think Super Metroid, but without the forced screen transitions. The first two points have me leaning toward Game Maker -- Plenty of 2D platformers have been made with it, and there are serviceable, openly available Sonic-the-Hedgehog-style physics engines for it that could be adapted to my needs with minimal muss and fuss. But the third makes me antsy -- from what limited information I hear, Game Maker has problems with large levels/boards/screens/whateveryoucallthem, thus necessitating transitions between screens. I want to avoid that if at all possible -- it would, I believe, fundamentally alter the flow of the game. I understand that generally speaking, the more you have loaded into memory the more things are going to chug (especially for a one-size-fits-all game development platform that isn't a model of efficient coding), but I'm hoping there are systems that can un-load objects that are sufficiently far offscreen and thus better produce seamlessness. Any thoughts, people? :) The sooner I can get a basic pre-fab physics engine and world-building program up and running, the sooner I can start prototyping areas and generally tooling around. Should I be looking at Game Maker, or elsewhere? (My current plan is to more-or-less build the game prototype-style, then worry about art and sound at the very end once the damn thing is playable.)

  • 2D/Isometric map algorithm

    - by Icarus Cocksson
    First of all, I don't have much experience on game development but I do have experience on development. I do know how to make a map, but I don't know if my solution is a normal or a hacky solution. I don't want to waste my time coding things, and realise they're utterly crap and lose my motivation. Let's imagine the following map. (2D - top view - A square) X: 0 to 500 Y: 0 to 500 My character currently stands at X:250,Y:400, somewhere near center of 100px above bottom and I can control him with my keyboard buttons. LEFT button does X--, UP button does Y-- etc. This one is kid's play. I'm asking this because I know there are some engines that automate this task. For example, games like Diablo 3 uses an engine. You can pretty much drag drop a rock to map, and it is automatically being placed here - making player unable to pass through/detect the collision. But what the engine exactly does in the background? Generates a map like mine, places a rock at the center, and checks it like: unmovableObjects = array('50,50'); //we placed a rock at 50,50 location if(Map.hasUnmovableObject(CurrentPlayerX, CurrentPlayerY)) { //unable to move } else { //able to move } My question is: Is this how 2D/Isometric maps are being generated or there is a different and more complex logic behind them?

  • Is it relatively safe to install kernel from "Canonical Kernel Team ppa" than "Mainline"

    - by tijybba
    I already referred most of the questions stating Upgrade from Mainline Builds or Compiling from latest source or PPA and also concluded that it can cause breakage to Current stable installed system. My question is regarding the kernel builds from Canonical Kernel Team which i have subscribed in Ubuntu 12.04 64-bit , states This is the core kernel team as hired by Canonical. Do not use this team, use ubuntu-kernel-team instead. My stable kernel states 3.2.0-27.42 from Ubuntu repository , also i consider Canonical Kernel Team to be Official ,currently urging me to Upgrade 3.2.0-27.43 , so from the Odd numbered and through the PPA description it is categorized as Unstable. From this ,it can be said next stable release would be 3.2.0-27.44. Is upgrading to .43 version is stable enough to continue , since .44 will be provide by Ubuntu itself based on .43 version and so on. Though i can't expect a lot of Changes ,but does it provide new Improvements or just Bug Fixes since it is just a preceding Release. Also , apart from Ubuntu mainline kernel , is Canonical Kernel Team different. If so , in what development or contribution terms. Is the Ubuntu kernel developed by Two different teams or same team. P.S.: Just noticed that sudo apt-get update && sudo apt-get upgrade provides me upgrade to .43 kernel , which normally requires sudo apt-get dist-upgrade to upgrade to newer kernel available , unless it normally provides message like " Following packages were not upgraded..." , is it an error or an exception to this Canonical Kernel PPA.

  • Migrating Forms to Java or ADF, the truth and no FUD

    - by Grant Ronald
    The question about migrating Forms to Java (or ADF or APEX) comes up time and time again.  I wanted to pull some core information together in a single blog post to address this question. The first question I always ask is "WHY" - Forms may still be a viable option for you so "if it ain't broke don't fix it".  Bottom line is whatever anyone tells you, its going to be a considerable effort and cost to migrate from Forms to something else so the business is going to want to know WHY you spend all those hard earned dollars switching from something that might have been serving you quite adequately. Second point, if you are going to switch, I would encourage you NOT to look at building a Forms clone.  So many times I see people trying to build an ADF application and EXACTLY mimic the Forms model - ADF is NOT a Forms clone.  You should be building to the sweet spot of your target technology, not your 20 year old client/server technology.  This is also the chance for the business to embrace change, so maybe look at new processes, channels and technology options that weren't available when you first developed your Forms applications. To help you understand what is involved, I've put together a number of resources. Thinking about migration of Forms to Java, ADF or APEX, read this to prepare yourself Oracle Forms to ADF: When, Why and How - this gives you an overview of our vision, directly from Oracle Product Management Redeveloping a Forms Application with Oracle JDeveloper and Oracle ADF.  This is a conference session from myself and Lynn Munsinger on how ADF can be used in a Forms migration/rewrite As someone who manages both Forms and ADF Product Management teams, I've a foot in either camp and am happy to see you use either tool.  However, I want you to be able to make an informed decision.  My hope is that there information sources will help you do that.

  • HDMI video output not working for external monitor

    - by user291852
    I have installed from scratch ubuntu GNOME 14.04 with gnome-flashback on my old HP HDX 16 laptop (core 2 duo p8600 + nvidia GT9600M + 4GB of ram) and I have problems with the HDMI output (I use it to extend my desktop on a dell U2412M 1920x1200 monitor). In the following I summarize the configurations that I have tried: Using the open source nouveau drivers, only the laptop monitor works, no signal from the external monitor connected to the HDMI output. However, the output of the xrandr command show that the HDMI output is connected with the correct resolution 1920x1200 (I find this thing really weird). Nouveau drivers with VGA connection works without problems on the external monitor, but the image is blurry compared to the HDMI connection. Using the nvidia drivers (I have tried different versions: nvidia-331-updates and the xorg-edgers versions nvidia-334 and nvidia-337) the HDMI output works, but I have system instabilities, random crashes and display freezes. I can't even enter in terminal mode with ctrl-alt-f1, so I have to manually shut down the laptop with the power button. I really would like to use the HDMI output with the nouveau drivers to avoid the system instabilities that I experienced with the nvidia drivers, but I can't figure out how to make it works.

  • SQL Azure Roadmap gets a little clearer &ndash; announcements from Tech Ed

    - by Eric Nelson
    On Monday at Tech?Ed 2010 we announced new stuff (I like new stuff) that “showcases our continued commitment to deliver value, flexibility and control of data through data cloud services to our customers”. Ok, that does sound like marketing speak (and it is) but the good news is there is some meat behind it. We have some decent new features coming and we also have some clarity on when we will be able to get our hands on those features.

  • Object behaviour or separate class?

    - by Andrew Stephens
    When it comes to OO database access you see two common approaches - the first is to provide a class (say "Customer") with methods such as Retrieve(), Update(), Delete(), etc. The other is to keep the Customer class fairly lightweight (essentially just properties) and perform the database access elsewhere, e.g. using a repository. This choice of approaches doesn't just apply to database access, it can crop up in many different OOD scenarios. So I was wondering if one way is preferable over the other (although I suspect the answer will be "it depends")! Another dev on our team argues that to be truly OO the class should be "self-contained", i.e. providing all the methods necessary to manipulate and interact with that object. I personally prefer the repository approach - I don't like bloating the Customer class with all that functionality, and I feel it results in cleaner code having it elsewhere, but I can't help thinking I'm seriously violating core OO concepts! And what about memory implications? If I retrieve thousands of Customer objects I'm assuming those with the data access methods will take up a lot more memory than the property-only objects?

  • Prognostications for the Future of BI

    - by jacqueline.coolidge(at)oracle.com
    Dashboard Insight has published the viewpoints on the future of BI from several vendors' perspectives including ours at Business Intelligence Predictions for 2011 We offered: In 2011, businesses will demand more from BI.  With intense competitive and economic pressures, it's not enough to be interesting.  BI must be actionable and enable people to respond smarter and faster to the opportunities and challenges of the day.  Most companies rely on BI to help them understand what's going on in their business.  Many are ready to make the leap from "What's going on?" to "What are we going to do about it?" Seamless integration from reporting to what-if analysis and scenario modeling helps businesses decide the right course of action.  The integration of BI with SOA and BPEL will deliver the true payoff for BI by enabling companies to initiate business processes directly from their analysis, turning insight to action for more agile and competitive business.  And, I must admit, it's tough to argue with the trends identified by other vendors. Enabling true self-service and engaging a larger community of users Accelerating the adoption of BI on mobile devices Embracing more advanced analytics such as data/text mining and location intelligence Price/performance breakthroughs It's singing to the choir.  I look forward to hearing the voices of some customers who are pushing the envelope and will post those stories as I capture them.

  • Using unordered_multimap as entity and component storage

    - by natebot13
    The Setup I've made a few games (more like animations) using the Object Oriented method with base classes for objects that extend them, and objects that extend those, and found I couldn't wrap my head around expanding that system to larger game ideas. So I did some research and discovered the Entity-Component system of designing games. I really like the idea, and thoroughly understood the usefulness of it after reading Byte54's perfect answer here: Role of systems in entity systems architecture. With that said, I have decided to create my current game idea using the described Entity-Component system. Having basic knowledge of C++, and SFML, I would like to implement the backbone of this entity component system using an unordered_multimap without classes for the entities themselves. Here's the idea: An unordered_mulitmap stores entity IDs as the lookup term, while the value is an inherited Component object. Examlpe: ____________________________ |ID |Component | ---------------------------- |0 |Movable | |0 |Accelable | |0 |Renderable | |1 |Movable | |1 |Renderable | |2 |Renderable | ---------------------------- So, according to this map of objects, the entity with ID 0 has three components: Movable, Accelable, and Renderable. These component objects store the entity specific data, such as the location, the acceleration, and render flags. The entity is simply and ID, with the components attached to that ID describing its attributes. Problem I want to store the component objects within the map, allowing the map have full ownership of the components. The problem I'm having, is I don't quite understand enough about pointers, shared pointers, and references in order to get that set up. How can I go about initializing these components, with their various member variables, within the unordered_multimap? Can the base component class take on the member variables of its child classes, when defining the map as unordered_multimap<int, component>? Requirements I need a system to be able to grab an entity, with all of its' attached components, and access members from the components in order to do the necessary calculations and reassignments for position, velocity, etc. Need a clarification? Post a comment with your concerns and I will gladly edit or comment back! Thanks in advance! natebot13

    - by mushfiq
    Hello, I have just left my college after doing graduation in computer engineering,during my college life I tried to do some freelancing in local market.I succeeded in the last year and earned some small amounts based on joomla,wordpress and visual basic based job.I had some small projects on php,mysql also. After finishing my undergrad life,I sat for an written test for post of python programmer and luckily I got the job and is working there(Its a small software firm do most of the task in python).Day by day I have gained some experience with core python. Meanwhile an USA based web service firm called me for the interview and after finishing three steps(oral+mini coding project+final oral)they selected me(i was wondered!).And I am going to join their with in few days.There I have to work in python(based on Django framework,I know only basic of this framework). My problem is when I started to work with python simultaneously I worked in Odesk as a wordpress,joomla,drupal,php developer. Now a days I am feeling that I am getting "Jack of all trades master of none". My current situation is i am familiar with several popular web technologies but not an expert.I want to make myself skilled. How should I organize myself to be a skilled web programmer?

  • Speed up loading of test results from builds in Visual Studio

    - by Jakob Ehn
    I still see people complaining about the long time it takes to load test results from a TFS build in Visual Studio. And they make a valid point, it does take a very long time to load the test results, even for a small number of tests. The reason for this is that the test results is not just the result of the test run but also all the binaries that were part of the test run. This often also means that the debug symbols (*.pdb) will be downloaded to your local machine. This reason for this behaviour is that it letsyou re-run the tests locally. However, most of the times this is not what the developer will do, they just want to know which tests failed and why. They can then fix the tests and rerun them locally. It turns out there is a way to load only the test results, which is much faster. The only tricky bit is to find the location of the .trx file that is generated during the build. Particularly in TFS 2010 where you often have multiple build agents, which of corse results in different paths to the trx file. Note: To use this you must have read permission to the build folder on the build agent where the build was executed. Open the build result for the build Click View Log Locate the part where MSTest is invoked. When using test containers, it looks like this:   Note: You can actually search in the log window, press Ctrl+F and you will get a little search box at the bottom. Nice! On the MSTest command line call, locate the /resultsfileroot parameter, which points to the folder where the test results are stored Note that this path is local for the build server, so you need to replace the drive letter with the server name: D:\Builds\Project\TestResults to \Project\TestResults">\\<BuildServer>\Project\TestResults Double-click on the .trx file and you will notice that it loads much faster compared to opening it from the build log window

  • Screen flickering when using midrange brightness values on Dell XPS

    - by Eliran Malka
    After a fresh Ubuntu install on my laptop, I discovered the function keys for screen brightness control (Fn+F4 and Fn+F5) are not working. Digging around here, I managed to get it to work by following the solution suggested on this post and that one, but alas — after applying it, a strange problem occurred: Setting the brightness level to any value other than minimum or maximum, the screen starts flickering back and forth from the selected level to full brightness, apparently due to Dell's power saver attempting to dim the screen to adjust the brightness levels. I looked up for a solution here on the site, and possibly everywhere, with no avail. Also tried: To manually control the brightness by configuring the ACPI level (setting values by echo [some_value] | sudo tee /sys/class/backlight/[vendor]_backlight/[some_key], without success.

  • Doing powerups in a component-based system

    - by deft_code
    I'm just starting really getting my head around component based design. I don't know what the "right" way to do this is. Here's the scenario. The player can equip a shield. The the shield is drawn as bubble around the player, it has a separate collision shape, and reduces the damage the player receives from area effects. How is such a shield architected in a component based game? Where I get confused is that the shield obviously has three components associated with it. Damage reduction / filtering A sprite A collider. To make it worse different shield variations could have even more behaviors, all of which could be components: boost player maximum health health regen projectile deflection etc Am I overthinking this? Should the shield just be a super component? I really think this is wrong answer. So if you think this is the way to go please explain. Should the shield be its own entity that tracks the location of the player? That might make it hard to implement the damage filtering. It also kinda blurs the lines between attached components and entities. Should the shield be a component that houses other components? I've never seen or heard of anything like this, but maybe it's common and I'm just not deep enough yet. Should the shield just be a set of components that get added to the player? Possibly with an extra component to manage the others, e.g. so they can all be removed as a group. (accidentally leave behind the damage reduction component, now that would be fun). Something else that's obvious to someone with more component experience?

  • Error message when running OpenGL programs with bumblebee

    - by user170860
    X Error of failed request: BadDrawable (invalid Pixmap or Window parameter) Major opcode of failed request: 152 (DRI2) Minor opcode of failed request: 8 (DRI2SwapBuffers ) Resource id in failed request: 0x4200005 Serial number of failed request: 2166 Current serial number in output stream: 2167 primus: warning: timeout waiting for display worker Segmentation fault (core dumped) I don't get this on all OGL programs, but only particularly GPU intense ones. Also, I only get this using primusrun. optirun gives the same error no matter what I run: [VGL] NOTICE: Pixel format of 2D X server does not match pixel format of [VGL] Pbuffer. Disabling PBO readback. I don't know what either of these mean. Neither of them stop the programs from running, but I'd like to fix the problem if there is one. Also, I prefer to use primusrun because it is faster and it does a better job with vertical sync, however, it only supports OGL 4.2. This isn't a big issue because the programs I write are forward compatible, but it still seems odd to me. So basically I'd just like it if someone could explain to me what is happening and if there is something I can do about it. Thanks.

  • What are the possible options for AI path-finding etc when the world is "partitionned"?

    - by Sebastien Diot
    If you anticipate a large persistent game world, and you don't want to end up with some game server crashing due to overload, then you have to design from the ground up a game world that is partitioned in chunks. This is in particular true if you want to run your game servers in the cloud, where each individual VM is relatively week, and memory and CPU are at a premium. I think the biggest challenge here is that the player receives all the parts around the location of the avatar, but mobs/monsters are normally located in the server itself, and can only directly access the data about the part of the world that the server own. So how can we make the AI behave realistically in that context? It can send queries to the other servers that own the neighboring parts, but that sounds rather network intensive and latency prone. It would probably be more performant for each mob AI to be spread over the neighboring parts, and proactively send the relevant info to the part that contains the actual mob atm. That would also reduce the stress in a mob crossing a border between two parts, and therefore "switching server". Have you heard of any AI design that solves those issues? Some kind of distributed AI brain? Maybe some kind of "agent" community working together through message passing?

  • importing animations in Blender, weird rotations/locations

    - by user975135
    This is for the Blender 2.6 API. There are two problems: 1. When I import a single animation frame from my animation file to Blender, all bones look fine. But when I import multiple (all of the frames), just the first one looks right, seems like newer frames are affected by older ones, so you get slightly off positions/rotations. This is true when both assigning PoseBone.matrix and PoseBone.matrix_basis. bone_index = 0 # for each frame: for frame_index in range(frame_count): # for each pose bone: add a key for bone_name in bone_names: # "bone_names" - a list of bone names I got earlier pose.bones[bone_name].matrix = animation_matrices[frame_index][bone_index] # "animation_matrices" - a nested list of matrices generated from reading a file # create the 'keys' for the Action from the poses pose.bones[bone_name].keyframe_insert('location', frame = frame_index+1) pose.bones[bone_name].keyframe_insert('rotation_euler', frame = frame_index+1) pose.bones[bone_name].keyframe_insert('scale', frame = frame_index+1) bone_index += 1 bone_index = 0 Again, it seems like previous frames are affecting latter ones, because if I import a single frame from the middle of the animation, it looks fine. 2. I can't assign armature-space animation matrices read from a file to a skeleton with hierarchy (parenting). In Blender 2.4 you could just assign them to PoseBone.poseMatrix and bones would deform perfectly whether the bones had a hierarchy or none at all. In Blender 2.6, there's PoseBone.matrix_basis and PoseBone.matrix. While matrix_basis is relative to parent bone, matrix isn't, the API says it's in object space. So it should have worked, but doesn't. So I guess we need to calculate a local space matrix from our armature-space animation matrices from the files. So I tried multiplying it ( PoseBone.matrix ) with PoseBone.parent.matrix.inverted() in both possible orders with no luck, still weird deformations.
