• Postfix count relayed messages per user

  - by Martino Dino

  I would like to know if it's possible to count the outgoing (relayed) messages on a per user basis in postfix. I'm managing a small commercial SMTP relay and decided that it would be nice to have a detailed daily report on how much mail a single user have sent (and eventually enforce some limits) possibly in realtime. I've looked almost everywhere and started to think that writing my own milter would be the way to go... Are you aware of anything that already exists for postfix that can count and report relayed mail for authenticated users (a script, milter or whatever)?

• How to shuffle pieces of large video files?

  - by Gabriël

  Hi Folks, For a party we want to show film-fragments using a projector. We have around 50 full-length movie avis and would like to shuffle them in shorter pieces. So every ca. 2-5 minutes another piece should begin. For example a sequence could be: Movie05-12m00s-14m30s, Movie08-55m50s-57m00s, Movie02-02m42s-06m40s, etc. So, random movies, at random positions within the movie of random lengths. What would be the kind of solution we're looking for? We were thinking 2 scenarios: Before doing this use some kind of tool to cut all avis in smaller pieces and put them on shuffle in a regular media player A sort of "VJ" program that can do this shuffle mixing realtime. Any suggestions for any of the above scenarios? Thanks!

• Cinema4D for game development tutorials anyone ?

  - by George Profenza

  Hi, I started to learn Cinema 4D. I've noticed it's really easy to use for motion graphics, but I want to use it for modeling for games/realtime 3d engines. Before I used 3dsmax and it was easy to estimate how a model would look/behave in a 3d engine. The two main things I did was displaying Polygon triangles and displaying the Polygon Count. I've found the Total Polygons tick in HUD settings in Cinema 4D, but I can't find any display mode that will show triangles. Is there there a way to display triangle faces/not quads in Cinema4D ? If so how ? There is a Triangulate function, but I'd rather not Triangulate/Untriangulate all the time, especially since it's converting back and forth between the two doesn't always produce the same result.

• Filtering serial port io

  - by mr odus

  I am currently working on a project where I communicate with hardware via a com port on its respective pc(win xp or 7) It is a fairly large project and sifting through the log file can be a bit of pain. This is my current setup. I use putty to do the actual serial communication, and write it to a log file. Then using MinGW Msys I filter it using tail -f "puttyLog" | grep -i "search term" Is there a better way to do this? I mean specifically filtering the input in realtime. Not that mine is terrible, but it still involves having to read from a log and sometimes there have been hangups where it will be delayed for a minute or 2. I have used software in the past with a main io window and then internal filter panels, but can no longer remember or find it.

• Animated HTTP request visualisation on Apache

  - by Simon Bennett

  This is more a question to appease my memory in trying to remember what it was I saw a while ago. I remember being introduced to a realtime server visualisation tool that showed the current requests that Apache was handling in a kind of fireworks effect on screen. Each request/group of requests would be shot across the screen in varying colours. I can't for the life for me remember what is was called and hunting around here and Google has left me empty handed. Just wondering if anybody else was able to plug this gem from the memory and ease my pain! Thanks

• How to have a soft-real-time process in presense of heavily swapping IO-intensive background load?

  - by Vi

  schedtool: PID 32301: PRIO 4, POLICY R: SCHED_RR , NICE -20, AFFINITY 0xf ionice: realtime: prio 4 But the music is stumbling anyway. Background load is low prio (SCHED_IDLEPRIO, idle ionice), but uses a lot of memory (more than is physically available) and does a lot of IO and calculations. Latencytop shows about 1500ms for: Following symlink Writing buffer to disk (sync) Page fault Writing a page to disk both for the bg load and for unrelated processes. Load average is 10 and counting. Why cannot it allocate, for example, 200MHZ of one of the cores and 32M of memory and not less than once per second opportunity for IO for mplayer to make it happy while continuing calculations on the background? Or: why it cannot leave background task and swap loving each other but keeping the rest of the system as if there were no background load? How to have RT processes AND heavy bg load simultaneously (without of virtual machines)?

• Synced audio ouput on multiple machines? VLC? hardware solutions?

  - by zimmer62

  I'm wondering if there is any software or hardware solutions to synced audio or audio and video across multiple computers or devices on a network. I've seen Sonos, and it might be a good solution, but it's also a very expensive solution. I'd like to be able to play something with realtime audio output on one PC, but hear it on speakers throughout the house, being it the home theater receiver, or another computer in another room. I saw a solution using the apple iport express, but the latency was unacceptable for anything other than just music. I'd like to avoid running audio wires with baluns to a bunch of amplifiers scattered all over the place when I have cat5 run everywhere. Is anyone familiar with using this kind of process for whole home audio? The latency is a big deal for me, if I've got video attached to the sound (e.g. watching a hockey game)

• Curiosity’s Descent to Mars in HD [Video]

  - by Jason Fitzpatrick

  Thanks to the Mars Descent Imager (MARDI) mounted on the fore-port side of Curiosity we’re treated to a high-resolution video of Curiosity’s descent to Mars. The video from MARDI, combined with the video editing of YouTube user DLFitch, yields the above video. He writes: This is a full-resolution version of the NASA Curiosity rover descent to Mars, taken by the MARDI descent imager. As of August 20, all but a dozen 1600×1200 frames have been uploaded from the rover, and those missing were interpolated using thumbnail data. The result was applied a heavy noise reduction, color balance, and sharpening for best visibility. The video plays at 15fps, or 3x realtime. The heat shield impacts in the lower left frame at 0:21, and is shown enlarged at the end of the video. Image source.

• Creating the concept of Time

  - by Jamie Dixon

  So I've reached the point in my exploration of gaming where I'd like to impliment the concept of time into my little demo I've been building. What are some common methodologies for creating the concept of time passing within a game? My thoughts so far: My game loop tendes to spend a fair bit of time sitting around waiting or user input so any time system will likely need to be run in a seperate thread. What I've currently done is create a BackgroundWorker passing in a method that contains a loop triggering every second. This is working fine and I can output information to the console from here etc. Inside this loop I have a DateTime object that is incrimented by 1 minute for every realtime second. (the game begins in the year 01/01/01) Is this a standard way of acheiving this result or are there more tried and tested methods? I'm also curious about how to go about performing time based actions (reducing player energy, moving entities around the game board, life/death etc). Thanks for any pointers or advice. I've searched around however I'm not familiar enough with the terms and so my searches are yeilding little result on this one.

• BlitzMax - generating 2D neon glowing line effect to png file

  - by zanlok

  Originally asked on StackOverflow, but it became tumbleweed. I'm looking to create a glowing line effect in BlitzMax, something like a Star Wars lightsaber or laserbeam. Doesn't have to be realtime, but just to TImage objects and then maybe saved to PNG for later use in animation. I'm happy to use 3D features, but it will be for use in a 2D game. Since it will be on black/space background, my strategy is to draw a series of white blurred lines with color and high transparency, then eventually central lines less blurred and more white. What I want to draw is actually bezier curved lines. Drawing curved lines is easy enough, but I can't use the technique above to create a good laser/neon effect because it comes out looking very segmented. So, I think it may be better to use a blur effect/shader on what does render well, which is a 1-pixel bezier curve. The problems I've been having are: Applying a shader to just a certain area of the screen where lines are drawn. If there's a way to do draw lines to a texture and then blur that texture and save the png, that would be great to hear about. There's got to be a way to do this, but I just haven't gotten the right elements working together yet. Any help from someone familiar with this stuff would be greatly appreciated. Using just 2D calls could be advantageous, simpler to understand and re-use. It would be very nice to know how to save a PNG that preserves the transparency/alpha stuff. p.s. I've reviewed this post (and many many others on the Blitz site), have samples working, and even developed my own 5x5 frag shaders. But, it's 3D and a scene-wide thing that doesn't seem to convert to 2D or just a certain area very well. I'd rather understand how to apply shading to a 2D scene, especially using the specifics of BlitzMax.

• Traffic estimation for a multiplayer flash game

  - by Steve Addington

  hey, i want to know if my rough traffic estimations are right, it would be for a pretty simple realtime flashgame in the style of haxball (but not as a soccer game) heres a video of it http://www.youtube.com/watch?v=z_xBdFg1RcI So here comes my estimation, i dont know if they are realistic! i hope someone can help me. consider the packet attached as a typical one sent every 200ms, its 148bytes + 64 bytes of header will make around a 200bytes packet. The server will receive 200bytes x 6 players x 5 times a sec=6000bytes/s=5.85Kbytes/s=46.9kbit/s plus he has to send all back to the players, so at this point are 94Kbit/s.The server received all the information, perform the definitive calculation and send the new position to all players, in a bigger packet of around 900bytes that have to be delivered to the others 6, which makes 900bytes x 6 players x 5 times a sec=27000bytes/s=26Kbytes/s=210kbit/s. overall that would be 26kbyte per second. thats like 130mb traffic per hour for a 6player room. but somehow i think the numbers are too high? that would be really much traffic for such a simple game. did i calculate something wrong?

• Why doesn't Unity's OnCollisionEnter give me surface normals, and what's the most reliable way to get them?

  - by michael.bartnett

  Unity's on collision event gives you a Collision object that gives you some information about the collision that happened (including a list of ContactPoints with hit normals). But what you don't get is surface normals for the collider that you hit. Here's a screenshot to illustrate. The red line is from ContactPoint.normal and the blue line is from RaycastHit.normal. Is this an instance of Unity hiding information to provide a simplified API? Or do standard 3D realtime collision detection techniques just not collect this information? And for the second part of the question, what's a surefire and relatively efficient way to get a surface normal for a collision? I know that raycasting gives you surface normals, but it seems I need to do several raycasts to accomplish this for all scenarios (maybe a contact point/normal combination misses the collider on the first cast, or maybe you need to do some average of all the contact points' normals to get the best result). My current method: Back up the Collision.contacts[0].point along its hit normal Raycast down the negated hit normal for float.MaxValue, on Collision.collider If that fails, repeat steps 1 and 2 with the non-negated normal If that fails, try steps 1 to 3 with Collision.contacts[1] Repeat 4 until successful or until all contact points exhausted. Give up, return Vector3.zero. This seems to catch everything, but all those raycasts make me queasy, and I'm not sure how to test that this works for enough cases. Is there a better way?

• What is the best way to "carve" a terrain created from a heightmap?

  - by tigrou

  I have a 3d landscape created from a heightmap. I'd like to "carve" some holes in that terrain. That will allow me to create bridges, caverns and tunnels inside it. That operation will be done in the game editor so it doesn't need to be realtime. In the end, rendering is done using traditional polygons. What would be the best/easiest way to do that ? I already think about several solutions : Solution 1 1) Create voxels from the heightmap (very easy). In other words, fill a 3D array like this : voxels[32][32][32] from the heightmap values. 2) Carve holes in the voxels as i want (easy too). 3) Convert voxels to polygons using some iso-surface extraction technique (like marching cubes). 4) Reduce (decimate) polygons created in 3). This technique seems to be the most promising for giving good results (untested). However the problem with marching cubes is that they tends to produce lots of polygons thus reducing them is mandatory. Implementing 4) also seems not trivial, i have read several papers on the web and it seems pretty complex. I was also unable to find an example, code snippet or something to start writing an algorithm for triangle mesh decimation. Maybe there is a special decimation algorithm (simpler) for meshes created from marching cubes ? Solution 2 1) Create some triangle mesh from the heighmap (easy). 2) Apply severals 3D boolean operation (eg: subtraction with a sphere) to carve the mesh. 3) apply some procedure to reduce polygons (optional). Operation 2) seems to be very complex and to be honest i have no idea how to do that. Also applying many boolean operation seems to be slow and will maybe degrade the triangle mesh every time a boolean operation is applied.

• In a 2D platform game, how to ensure the player moves smoothly over sloping ground?

  - by Kovsa

  See image: http://i41.tinypic.com/huis13.jpg I'm developing a physics engine for a 2D platform game. I'm using the separating axis theorem for collision detection. The ground surface is constructed from oriented bounding boxes, with the player as an axis aligned bounding box. (Specifically, I'm using the algorithm from the book "Realtime Collision Detection" which performs swept collision detection for OBBs using SAT). I'm using a fairly small (close to zero) restitution coefficient in the collision response, to ensure that the dynamic objects don't penetrate the environment. The engine mostly works fine, it's just that I'm concerned about some edge cases that could possibly occur. For example, in the diagram, A, B and C are the ground surface. The player is heading left along B towards A. It seems to me that due to inaccuracy, the player box could be slightly below the box B as it continues up and left. When it reaches A, therefore, the bottom left corner of the player might then collide with the right side of A, which would be undesirable (as the intention is for the player to move smoothly over the top of A). It seems like a similar problem could happen when the player is on top of box C, moving left towards B - the most extreme point of B could collide with the left side of the player, instead of the player's bottom left corner sliding up and left above B. Box2D seems to handle this problem by storing connectivity information for its edge shapes, but I'm not really sure how it uses this information to solve the problem, and after looking at the code I don't really grasp what it's doing. Any suggestions would be greatly appreciated.

• Issue tracking multiple domains with Google Analytics

  - by user359650

  I have 2 domains mydomain.com and mydomain.net which I'm trying to track with the same GA code. Here are the options I turned on: Subdomains of mydomain ON Examples: www.mydomain.com -and- apps.mydomain.com -and- store.mydomain.com Multiple top-level domains of mydomain ON Examples: mydomain.uk -and- mydomain.cn -and- mydomain.fr Which gave me the following code: _gaq.push(['_setAccount', 'UA-123456789-1']); _gaq.push(['_setDomainName', 'mydomain.com']); _gaq.push(['_setAllowLinker', true]); _gaq.push(['_trackPageview']); In this help page I read that _setDomainName must be changed for each domain which I did: -if you go to mydomain.net you get _gaq.push(['_setDomainName', 'mydomain.net']); -if you go to mydomain.com you get _gaq.push(['_setDomainName', 'mydomain.com']); When I generate traffic on both mydomain.dom and mydomain.net and watches GA push requests made with firebug I can see requests generated for both domains and the parameter called utmhn has the proper domain value (which matches that of _setDomainName and the browser address bar). However when I monitor the realtime statistics under Home->Real-Time->Overview I see pageviews for mydomain.net BUT NOT for mydomain.dom :( What am I missing to properly track both domains? PS: in the help page I mentioned they talk about setting up cross links which I didn't do for now as my understanding is that it shouldn't be needed to get what I'm trying to do to work. Also I want to mention that I do not have any tracking code for any of these 2 domains other than the one I mentioned.

• Designing a flexible tile-based engine

  - by Vee

  I'm trying to create a flexible tile-based game engine to make all sorts of non-realtime puzzle games, just as Bejeweled, Civilization, Sokoban, and so on. The first approach I had was to have a 2D array of Tile objects, and then have classes inheriting from Tile that represented the game objects. Unfortunately that way I couldn't stack more game elements on the same Tile without having a 3D array. Then I did something different: I still had the 2D array of Tile objects, but every Tile object contained a List where I put and different entities. This worked fine until 20 minutes ago, when I realized that it's too expensive to do many things, look at this example: I have a Wall entity. Every update I have to check the 8 adjacent Tiles, then check all of the entities in the Tile's List, check if any of those entities is a Wall, then finally draw the correct sprite. (This is done to draw walls that are next to each other seamlessly) The only solution I see now is having a 3D array, with many layers, that could suit every situation. But that way I can't stack two entities that share the same layer on the same tile. Whenever I want to do that I have to create a new layer. Is there a better solution? What would you do?

• How to design a high-level application protocol for metadata syncing between devices and server?

  - by Jaanus

  I am looking for guidance on how to best think about designing a high-level application protocol to sync metadata between end-user devices and a server. My goal: the user can interact with the application data on any device, or on the web. The purpose of this protocol is to communicate changes made on one endpoint to other endpoints through the server, and ensure all devices maintain a consistent picture of the application data. If user makes changes on one device or on the web, the protocol will push data to the central repository, from where other devices can pull it. Some other design thoughts: I call it "metadata syncing" because the payloads will be quite small, in the form of object IDs and small metadata about those ID-s. When client endpoints retrieve new metadata over this protocol, they will fetch actual object data from an external source based on this metadata. Fetching the "real" object data is out of scope, I'm only talking about metadata syncing here. Using HTTP for transport and JSON for payload container. The question is basically about how to best design the JSON payload schema. I want this to be easy to implement and maintain on the web and across desktop and mobile devices. The best approach feels to be simple timer- or event-based HTTP request/response without any persistent channels. Also, you should not have a PhD to read it, and I want my spec to fit on 2 pages, not 200. Authentication and security are out of scope for this question: assume that the requests are secure and authenticated. The goal is eventual consistency of data on devices, it is not entirely realtime. For example, user can make changes on one device while being offline. When going online again, user would perform "sync" operation to push local changes and retrieve remote changes. Having said that, the protocol should support both of these modes of operation: Starting from scratch on a device, should be able to pull the whole metadata picture "sync as you go". When looking at the data on two devices side by side and making changes, should be easy to push those changes as short individual messages which the other device can receive near-realtime (subject to when it decides to contact server for sync). As a concrete example, you can think of Dropbox (it is not what I'm working on, but it helps to understand the model): on a range of devices, the user can manage a files and folders—move them around, create new ones, remove old ones etc. And in my context the "metadata" would be the file and folder structure, but not the actual file contents. And metadata fields would be something like file/folder name and time of modification (all devices should see the same time of modification). Another example is IMAP. I have not read the protocol, but my goals (minus actual message bodies) are the same. Feels like there are two grand approaches how this is done: transactional messages. Each change in the system is expressed as delta and endpoints communicate with those deltas. Example: DVCS changesets. REST: communicating the object graph as a whole or in part, without worrying so much about the individual atomic changes. What I would like in the answers: Is there anything important I left out above? Constraints, goals? What is some good background reading on this? (I realize this is what many computer science courses talk about at great length and detail... I am hoping to short-circuit it by looking at some crash course or nuggets.) What are some good examples of such protocols that I could model after, or even use out of box? (I mention Dropbox and IMAP above... I should probably read the IMAP RFC.)

• Send less Server Data with "AFK"

  - by Oliver Schöning

  I am working on a 2D (Realtime) MultiPlayer Game. With Construct2 and a Socket.IO JavaScript Server. Right now the code does not include the Array for each Player. var io = require("socket.io").listen(80); var x = 10; io.sockets.on("connection", function (socket) { socket.on("message", function(data) { x = x+1; }); }); setInterval(function() { io.sockets.emit("message", 'Pos,' + x); },100); I noticed a very annoying problem with my server today. It sends my X Coordinates every 100 milliseconds. The Problem was, that when I went into another Browser Tab, the Browser stopped the Game from running. And when I went back, I think the Game had to run through all the packages. Because my Offline Debugging Button still worked immediately and the Online Button only responded after some seconds. So then I changed my Code so that it would only send out an update when it received a player Input: var io = require("socket.io").listen(80); var x = 10; io.sockets.on("connection", function (socket) { socket.on("message", function(data) { x = x+1; io.sockets.emit("message", 'Pos,' + x); }); }); And it Updated Immediately, even when I had been inactive on the Browser Tab for a long time. Confirming my suspicion that it had to get through all the data. Confirm Please! It would be insane to only send information on Client Input in a Real Time Game. But how would I write a AFK function? I would think it is easier to run a AFK Boolean Loop on the Server. Here is what I need help for: playerArray[Me] if ( "Not Given any Input for X amount of Seconds" ) { "Don't send Data" } else { "Send Data" }

• Use a SQL Database for a Desktop Game

  - by sharethis

  Developing a Game Engine I am planning a computer game and its engine. There will be a 3 dimensional world with first person view and it will be single player for now. The programming language is C++ and it uses OpenGL. Data Centered Design Decision My design decision is to use a data centered architecture where there is a global event manager and a global data manager. There are many components like physics, input, sound, renderer, ai, ... Each component can trigger and listen to events. Moreover, each component can read, edit, create and remove data. The question is about the data manager. Whether to Use a Relational Database Should I use a SQL Database, e.g. SQLite or MySQL, to store the game data? This contains virtually all game content like items, characters, inventories, ... Except of meshes and textures which are even more performance related, so I will keep them in memory. Is a SQL database fast enough to use it for realtime reading and writing game informations, like the position of a moving character? I also need to care about cross-platform compatibility. Aside from keeping everything in memory, what alternatives do I have? Advantages Would Be The advantages of using a relational database like MySQL would be the data orientated structure which allows fast computation. I would not need objects for representing entities. I could easily query data of objects near the player needed for rendering. And I don't have to take care about data of objects far away. Moreover there would be no need for savegames since the hole game state is saved in the database. Last but not least, expanding the game to an online game would be relative easy because there already is a place where the hole game state is stored.

• Gathering application architecture

  - by userbb

  Suppose there is system for gathering info about system activities. There is a client part with an interface and there are agent parts that are installed on each machine. I estimate that there could be max 20 computers now. Later could be more like 50. My solutions: Agent stores data into local database e.g. sqlite. There is also a service which can be used by a client to query data. So if a client wants to display data for 50 computers, he sends a query to 50 computers. I'am on that solution now but maybe it's totally wrong. Agent stores data into local database (I don't known good one for that). There is also server (main database) and local databases are synchronized with the server. In this case, a client connects to the main database to display data. Agent sends data in realtime to main database. So same as point 2, but there is no sync. Like in point 3, but agent buffers data in local database and sends it in small chunks to main database. What is the best approach?
