• No sound Ubuntu 12.04 through HDMI

  - by MikeMan

  Specs: Asus G73JH i7/720; ATI Mobility 5870 I have read through a lot of threads on getting HDMI sound to work and non of them have fixed my issue. Granted I am very new to Linux and know only the GUI aspect of what it does from finding similarities that Windows 7 has. I would like to become a Linux Power User and I figured this would be a good step to get started. I was able to successfully install my graphics driver and it shows in use. I connect the HDMI to my HD TV and I get no sound. I don't care about auto switch for sound, that would be great but not necessary. I just want my sound to work through the HDMI. What I have tried: Changed GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1" pact set-card-profile 0 output:hdmi-surround Failure: no such entity Sound Settings: Right-click Sound indicator ? Sound Settings ? Output Tab, and set Digital Output (S/PDIF) Built in Audio Speakers Built in Audio I only get 2 settings. If I right-click the area below those 2 in the "play sound through" box, I get no "show hidden devices". I am also doing all this with the HDMI connected to eliminate any possibility for error.

• Should I go with Java or Python for my next project, after using PHP for 5 years? [closed]

  - by vim

  I have a full-time PHP job and I've been working with PHP for 5 years. I'm not willing to stay within this technology stack any more. I also worked with Java for 2 year before, so for me it looks more obvious to switch back to Java. However during last 5 years I was thinking about starting my own project, and now I think I have a very good SAAS idea. I'm completely confused what technology should I use for my project. I don't want to do it in PHP, and after reading many articles about rapid prototype development it seems to me that Django is the best option. I will continue to work full time for my current employer because I need to pay my bills and will work on my project in my free time. The concern I have is should I do my project in Java or Python? To be realistic there is always a risk when you are doing your own project/start-up. If I do it in Java in the worst case scenario I believe I will be able to find a full time Java position because I already have some experience in Java + recent experience in my project. With regards to Python it looks like it is not very popular in my area and salaries are much more lower then for Java. On the other hand I have a feeling that if I chose Java it will take me a way longer to finish my project. Guys I'm completely confused and I need your advice. P.S. I have moved to London 2 years ago from another country, local guys are very welcome to share their thoughts about London's job market.

• Java or Python? Career/Start-up advice needed [closed]

  I have a full-time PHP job and I've been working with PHP for 5 years. As you can guess after spending 5 years I'm not willing to stay within this technology stack any more.

• Oracle Virtual Desktop Infrastructure

  - by Fat Bloke

  A lot of the recent blog entries here have been about Oracle VM VirtualBox, possibly the coolest personal desktop virtualization product known to man. Deploying VirtualBox on your PC or Mac lets you run many virtual desktops at the same time to one user, you. But did you know that VirtualBox can also power an Enterprise-scale virtual desktop deployment too, delivering many desktops to many users?  As part of another Oracle product, Oracle Virtual Desktop Infrastructure (VDI), VirtualBox can run your Windows, Linux or Solaris desktops on servers located in the datacenter. Oracle VDI orchestrates the whole deal by looking after : creating or cloning the virtual desktops from a master template; managing the lifecycle of the desktops (create, start, suspend, resume, stop, delete); assigning which users get which desktops;  delivering easy and fast access to these virtual desktops from almost any device, such as existing PCs or Macs, iPads, or specially designed Sun Ray client devices too; load balancing and session management of all of this.  Architecturally the solution looks something like this: This is an increasingly hot area of the IT landscape, so the Fat Bloke has decided to create a new blog category (VDI) and dedicate a few blog entries to look into this in a bit more detail over the next few weeks.

• Advice on whether to use scripting, run time compile or something else

  - by Gaz83

  I work in the prodution area at my works and I design and create the software to run our automated test equipment. Everytime I get involved with a new machine I end up with a different and (hopefully) better design. Anyway I have come to the point where I feel I need to start standardization all the machines with the same program. I see a problem when it comes to applying updates as at the moment the test procedures are hard coded into the program at each station. I neeed to be able to update the core program without affecting the testing section. The way I see it that this will mean splitting the program into 2 sections. Main UI - This is the core that talks to everything on the machine such as cameras, sensors, printer etc and is a standalone application. Test Procedure - This is the steps that is executeted everytime the machine runs through a test. The main UI will load the test procedure and execute when ever a test is required. My question is what is the best approach to this in terms of having an application load a file and execute the code with in? Take into account that the code in the test procedure will need access to public methods on the UI/core system to communicate to sensors etc. I have heard about MS Roslyn and had a quick look, would this solve my issue?

• trying to setup multiple primary partitions on ubuntu linux

  - by JohnMerlino

  I currently have ubuntu desktop installed on a harddrive. I want to partition the harddrive so that I can reserve 30 gigs for ubuntu server and 30 gigs for ubuntu desktop. The drive has 300 gigs available. Right now I am booting from dvd drive and installing ubuntu server. I selected "Guided partitioning" and created a 30 gig primary partition of Ext4 journaling filesystem, set "yes, format it" for format partition and set bootable flag to on. I intend to use this 30 gig partition to hold ubuntu server and allow me to boot from it. Now I have two other partitions. They are both set to "logical", one is currently using 285.8 gigs and is using ext4 (when I try to set bootable flag to true, it gives a warning "You are trying to set the bootable flag on a logical partition. The bootable flag is only useful on the primary partitions"). More alarming it says "No existing file system was detected in this partition". Actually, Im thinking that this is the parittion that is supposed to be holding my current Ubuntu Desktop. And of course I want this to be bootable and be a primary partition, so I could dual boot from this and the server partition. Now the third partition is also set to logical and it is being used as swap area. My question is regarding that second partition. Its supposed to be a primary partition thats holding my existing ubuntu desktop edition. How do I switch it to primary and to make sure that its pointing to my existing desktop installation?

• How to go about designing an intermediate routing filter program to accept input and forward accordingly?

  - by phileaton

  My predicament: I designed an app, written in Python, to read my mail and check for messages that contain a certain digital signature. It opens these and looks for keywords. If the message contains these keywords, certain related functions area executed on the computer. It is a way I can control my computer from my cell phone without being there. I am still in the beginning stages and it can only currently remotely open and close applications/processes. The obvious issue is security risks. I hoped to spearhead that by requiring and checking for that digital signature. However, my issue comes when I'd like to make this program usable by multiple users. The idea is that the user will send keywords: username and password, for instance, to log into their personal email account and send messages to it to be parsed. Please ignore the security implications of sending non-encoded passwords through email. (Though if you could help me on that part I'd much appreciate it as well, but currently, that is not the scope of my question.) My issue is designing an intermediary process that will take an email/password to read an email and scan for those keywords. The issue is, that the program has to be accessing an email to read the email for the username/password! I have got myself into a loop and cannot figure out how to have this required intermediary program. I could just create an arbitrary email account and have that check for login-creds, but is there a better way of doing this than that? Also, is there a better way of communicating with a computer remotely than this? Especially if the computer is not a server and is behind a router with only a subnet ip? If I am asking this question in the wrong place, I deeply apologize. Any help would be much appreciated!

• Android Bitmap: Collision Detecting

  - by Aekasitt Guruvanich

  I am writing an Android game right now and I would need some help in the collision of the Pawns on screen. I figured I could run a for loop on the Player class with all Pawn objects on the screen checking whether or not Width*Height intersects with each other, but is there a more efficient way to do this? And if you do it this way, many of the transparent pixel inside the rectangular area will also be considered as collision as well. Is there a way to check for collision between Bitmap on a Canvas that disregard transparent pixels? The class for player is below and the Pawn class uses the same method of display. Class Player { private Resources res; // Used for referencing Bitmap from predefined location private Bounds bounds; // Class that holds the boundary of the screen private Bitmap image; private float x, y; private Matrix position; private int width, height; private float velocity_x, velocity_y; public Player (Resources resources, Bounds boundary) { res = resources; bounds = boundary; image = BitmapFactory.decodeResource(res, R.drawable.player); width = image.getWidth(); height = image.getHeight(); position = new Matrix(); x = bounds.xMax / 2; // Initially puts the Player in the middle of screen y = bounds.yMax / 2; position.preTranslate(x,y); } public void draw(Canvas canvas) { canvas.drawBitmap(image, position, null); } }

• What is the standard way of using Q15 values?

  - by Alex

  To process 8-bit pixels, to do things like gamma correction without losing information, we normally upsample the values, work in 16 bits or whatever, and then downsample them to 8 bits. Now, this is a somewhat new area for me, so please excuse incorrect terminology etc. For my needs I have chosen to work in "non-standard" Q15, where I only use the upper half of the range (0.0-1.0), and 0x8000 represents 1.0 instead of -1.0. This makes it much easier to calculate things in C. But I ran into a problem with SSSE3. It has the PMULHRSW instruction which multiplies Q15 numbers, but it uses the "standard" range of Q15 is [-1,1-2?¹5], so multplying (my) 0x8000 (1.0) by 0x4000 (0.5) gives 0xC000 (-0.5), because it thinks 0x8000 is -1. This is quite annoying. What am I doing wrong? Should I keep my pixel values in the 0000-7FFF range? This kind of defeats the purpose of it being a fixed-point format. Is there a way around this? Maybe some trick? Is there some kind of definitive treatise on Q15 which discusses all this?

• Can I eventually consider myself a professional developer if I don't have a CS degree? [on hold]

  - by heltonbiker

  Question first, context later: If I am a dedicated, self-taught programmer, always seeking top-quality books AND READING THEM, while successfully applying all that new knowledge into my current work, could I call myself (and offer my work as) a PROFESSIONAL developer? How limiting (or how common) that is nowadays? I am afraid that, no matter how hard I study and practice, it could be too difficult to compete with "actual", college graduated developers, and potential employers might have doubts investing in an "undergraduated" person. Now, context: My former profession is from healthcare sector, then I studied mechanical engineering (quit in the middle), then I studied product design (master degree), and I ended up working (very happily) at an engineering company that manufactures medical devices. For more than two years now my main activity in this company is software development. The devices contain software, and we gave up hiring software development (domain knowledge needed, too much communication cost). My current company sees a lot of value in what I do, but I cannot afford the risk of depending on this single company for the rest of my life, you get it. But a lot of job offers require some minimal formal education, usually a CS degree. Fact is that I am sure this is my target profession, I don't plan to go to another area, it is a pleasure to dive into books that normal people would consider unreadable, but I'm 36 years old and can't see going back to college as a viable alternative.

• Strategy to store/average logs of pings

  - by José Tomás Tocino

  I'm developing a site to monitor web services. The most basic type of check is sending a ping, storing the response time in a CheckLog object. By default, PingCheck objects are triggered every minute, so in one hour you get 60 CheckLogs and in one day you get 1440 CheckLogs. That's a lot of them, I don't need to store such level of detail, so I've set a up collapsing mechanism that periodically takes the uncollapsed CheckLogs older than 24h and collapses (averages) them in intervals of 30 minutes. So, if you have 360 CheckLogs that have been saved from 0:00 to 6:00, after collapsing you retain just 12 of them. The problem.. well, is this: After averaging the response times, the graph changes drastically. What can I do to improve this? Guess one option could be narrowing the interval duration to 15 min. I've seen the graphs at the GitHub status page and they do not seem to suffer from this problem. I'd appreciate any kind of information you could give me about this area.

• How to maintain a demo version of an application?

  - by O.O

  I need to be able to demo our production application to prospective clients. The way I have it setup today is simple. The demo application is an exact duplicate of the production system, except that the data in the database is obfuscated to protect our current clients' data. This works great because it doesn't require any application changes. Boss dropped a potential BOMBSHELL today and said that the demo system needs to contain a special link and that ONLY shows up on demo. He went on to explain that in the future there may be much bigger differences between the demo and production apps (e.g. an entire area of functionality). What do I do now? Some things I have thought about doing: Maintain a different branch in subversion specific to the demo system Create an installation package that has the changes for demo, then revert and build a production installation package Modularize the application (no idea how) Say: "Screw you! I will not do it!" (LOL) Use some sort of conditional logic in the app to determine if it is a demo or a production app. E.g. (if the URL contains 'demo' then show else hide). If you haven't guessed by now, this is a web application Anyways, I have no experience in this scenario as to which one is better or if none of these are any good. Anyone have an answer, strategy, something!?

• Working Qt controls in a 3d environment

  - by Jay

  I need some advice from a Qt expert. The background: I have a 3D engine (ogre3d) working in concert with Qt. The 3D Content is displayed in a widget (using a custom OS window in the client area). I'm able to overlay arbitrary Qt widgets onto the 3d world using the widget render() method and a shared bitmap. This makes a great "heads up display". I can use the standard Qt style sheets and animation using this technique. My goal I'd like to go a step further and allow the user to move these rendered widgets using the mouse. I'd like some advice on the best way to implement this. Possible solutions: The widgets in the HUD are not part of the inheritance chain. I render them manually. They don't get events though. I could add them to the inheritance chain so they get events in the usual way. Then I would need to change them to render to my shared bitmap instead of to the operating system. I looked at this once but couldn't find enough information to implement it. Capture mouse events in the 3D display widget and EMIT them to child controls. I basically create my own event handling chain. Any suggestions on how to implement this? I'm also considering switching to Qt5. I'm not sure how that might affect this decision.

• Rectangular Raycasting?

  - by igrad

  If you've ever played The Swapper, you'll have a good idea of what I'm asking about. I need to check for, and isolate, areas of a rectangle that may intersect with either a circle or another rectangle. These selected areas will receive special properties, and the areas will be non-static, since the intersecting shapes themselves will also be dynamic. My first thought was to use raycasting detection, though I've only seen that in use with circles, or even ellipses. I'm curious if there's a method of using raycasting with a more rectangular approach, or if there's a totally different method already in use to accomplish this task. I would like something more exact than checking in large chunks, and since I'm using SDL2 with a logical renderer size of 1920x1080, checking if each pixel is intersecting is out of the question, as it would slow things down past a playable speed. I already have a multi-shape collision function-template in place, and I could use that, though it only checks if sides or corners are intersecting; it does not compute the overlapping area, or even find the circle's secant line, though I can't imagine it would be overly complex to implement. TL;DR: I need to find and isolate areas of a rectangle that may intersect with a circle or another rectangle without checking every single pixel on-screen.

• New Solaris 11.2 beta features: SMF stencils

  - by user13366125

  As much as there is often a lot discussion about configuration items inside the SMF repository (like the hostname), it brings an important advantage: It introduces the concept of dependencies to configuration changes. What services have be restarted when i change a configuration item. Do you remember all the services that are dependent on the hostname and need a restart after changing it? SMF solves this by putting the information about dependencies into it configuration. You define it with the manifests. However, as much configuration you may put into SMF, most applications still insists to get it's configuration inside the traditional configuration files, like the resolv.conf for the resolver or the puppet.conf for Puppet. So you need a way to take the information out of the SMF repository and generate a config file with it. In the past the way to do so, was some scripting inside the start method that generated the config file before the service started. Solaris 11.2 offers a new feature in this area. It introduces a generic method to enable you to create config files from SMF properties. It's called SMF stencils. (read more)

• Managing game objects/components

  - by Xeon06

  Good day everyone, By far the biggest problem that has always dawned on my when programming games is how to structure my code. It just becomes an incredible mess after a while. The reason for that is because I have no idea how different classes should interact with each other. Let's have an example. Say I have a class Player, a class PlayerInput and a class Map. The player class contains information as to the location of the player, whereas the player input class handles changing that location, but by first making sure it's within a walkable area from the map class. How to structure this? My usual approach is to pass those components as parameters in the constructors of the parameters that need them, like so: var map = new Map(); var player = new Player(); var input = new PlayerInput(player, map); The problem with that is that it quickly gets messy, when you add new components you have to go through your constructors and update them, and it doesn't work well if you have mirroring references: var physics = new Physics(input); //Oops, doesn't work var input = new Input(physics); So, how do you guys usually manage this? Thanks.

• Selecting objects on a 2D map

  - by Dave

  I have a object selection function by checking the mouse click and getting the relevant object. How ever there is a rare situation where if one object is partially behind the other then both objects are in the given area so im wondering how I can make the game know which one was selected, as currently my method does not know. This is my function that works it out: function getobj(e){ mx = e.pageX - curleft; //mouse click x my = e.pageY - curtop; //mouse click y function searchSprites(sprites, x, y) { var matches = [], i = 0, data = null; for (i = 0; i < spritea.length; ++i) { data = spritea[i].data; if (x > data[0] && y > data[1] && x < data[2] && y < data[3]) { var imageData = ctx2.getImageData(x, y, 1, 1); if(imageData.data[3] !== 0){ return [spritea[i].id]; i = spritea.length; } } } } res = searchSprites(spritea, mx, my); bid = res[0]; if(bid === '1'){ alert('You selected the skyscraper in front!'); }else if(bid === '3'){ alert('You selected the skyscraper behind!'); } } Image of the map: It keeps telling me I clicked the skyscraper behind which is not necessarily what the user is trying to do. How can I improve the accuracy of this ?

• How you choose your first job as a programmer? [on hold]

  - by sliter

  For Brief I am a recently graduated CS student. I am looking for a job these days, but I have no idea what kind of software development jobs I like(embedded system,web development or else...). And I am looking for your advice. Here is a little more While I was a student, I had an one year internship experience as a system engineer in a semi-conductor company where I wrote Linux driver, tuned system performance, etc.. I was happy about this experience as it allowed me to deepen my understanding of the operating system and different low level things. And I thought "Em, I will continue in the embedded area after I graduate". At the end of my study, I am doing an another internship in web development, both front-end and back-end. And I also enjoys a lot the process of learning new things and making it work (Backbone, Node, socketio, etc..). Now, when I am looking for a software development position, I do not know what to apply! All I know is that I want a job which allows me to keep up with the trends instead of repeating. But besides this, I've no idea what specific type of job I want to do. Turn back to embedded system? Continue with web development? Change to other promising areas(data mining)? All these development positions makes no big difference to me. But I think this is not good and I need some criteria at choosing. So I am looking for advice and I would really appreciate if you can share your experience.

• Provide A Scrolling "Camera" View Over A 2D Game Map

  - by BitCrash

  I'm in the process of attempting to create a 2D MMO type game with Kryonet and some basic sprites, mostly for my own learning. I have the back end set up great (By my standards) and I'm moving on to actually getting some things drawn onto the map. I cannot for the life of me figure out a solid way to have a "Camera" follow a player around a large area. The view pane for the game is 640 x 480 pixels, and each tile is 32x32 pixels (Thats 20 tiles wide and 15 high for the viewpane) I have tried a couple things to do this, but they did not seem to work out so well. I had a JScrollPane with 9 "Viewpane"-sized canvases in it, and tried to have the JScrollPane move in accordance with the player. The issue came when I reached the end of the JScrollPane. I tried to "Flip" canvases, sending the canvas currrently drawing the player to the middle of the 9 and load the corresponding maps onto the other ones. It was slow and worked poorly. I'm looking for any advice or previous experience with this; any ideas? Thank you! Edit and Clarification: I did not mean to mention Kryonet, I was merely providing peripheral information in case there was something that would help which I could not foresee. Instead of having an array of 9 canvases, why not just have one large canvas loading a large map every once in a while? I'm willing to have "load times" where as with the canvas array I would have none (in theory) to give the user a smooth experience. I could just change the size and location of the map with a modified setBounds() call on the canvas in a layered pane (layered because I have hidden swing items, like inventories and stuff) I'll try it out and post here how it goes for people asking the same question.

• SDL blitting multiple surfaces at once

  - by extropic_engine

  I'm trying to write a platforming game where the sprites for the level backgrounds are broken up into 512x512 chunks. I keep 3 chunks in memory at a time and I'm trying to write code to blit all three to the screen. Here is the current code I have: SDL_Rect where; where.y = -game->camera->y; where.x = -game->camera->x - MAP_WIDTH; SDL_BlitSurface(left_chunk, NULL, screen, &where); where.x = -game->camera->x; SDL_BlitSurface(center_chunk, NULL, screen, &where); where.x = -game->camera->x + MAP_WIDTH; SDL_BlitSurface(right_chunk, NULL, screen, &where); The issue I'm running into is that whichever chunk gets blitted first is the only one that shows up. The rest fail to appear onscreen. I think the issue might have something to do with alpha transparency, but even if the chunks don't overlap at all they still fail to blit. In other parts of the code I'm blitting multiple things to the screen at once, such as characters and backgrounds, and they all show up correctly. This particular segment of code is the only area I'm encountering this problem. If I comment out the line that blits left_chunk, it changes to this:

  Im using a brand new Dell XPS notebook (bought mar 2012) which has 4.5 hrs battery life using a 6 cell battery-when i use windows 7. The machine uses an Intel core 17 2670qm processor, and a 64 bit operating system. I downloaded Ubuntu 11.10 and installed it on a USB drive, which is how i use it. I still have Windows 7 on the machine. When the machine is booting up I hit F12, and run Ubuntu from the flash drive instead of the machine booting Windows, as it normally would. On the Ubuntu menu, on the top right area, there is a battery menu, which shows how long to charge battery, or how much life left etc..with a fully charged battery the most Ubuntu will give me is 1.5 hrs. I've adjusted all power setting etc by clicking on the battery meter where i can make these adjustments, and have even turned down the brightness on the monitor. I've read through these questions here, and a user wrote to install Ubuntu 12(?)(the alpha version) when it's out this month(april), and this has better power management. Other forums (Ubuntu wiki) state that windows 7 controls power management effectively because it's configured to work with the hardware. I'd like to install Ubuntu and wipe windows but can't because of this issue. I need my notebook to go hours, not an hour and a bit. Can anybody recommend possibly a good software to use, that will work with the machines bios under Ubuntu? Another thought of mine, is- since I didn't yet wipe windows off my hard disk, is windows still possibly controlling the power mgmt aspect on the machine? I've thought of calling tech support at Dell and asking for help there, maybe Dell has something (a tweak?), I can download that'll work under Ubuntu. Looking forward to any help/suggestions i can get here, i'm really stuck on this..

• Should I be worrying about limiting the number of textures in my game?

  - by Donutz

  I am working on a GUI in XNA 4.0 at the moment. (Before you point out that there are many GUIs already in existance, this is as much a learning exercise as a practical project). As you may know, controls and dialogs in Windows actually consist of a number of system-level windows. For instance, a dialog box may consist of a window for the whole dialog, a child window for the client area, another window (barely showing) for the frame, and so on. This makes detecting mouse hits and doing clipping relatively easy. I'd like to design my XNA GUI along the same lines, but using overlapping Textures instead of windows obviously. My question (yes, there's actually a question in this drivel) is: am I at risk of adversely affecting game performance and/or running low in resources if I get too nuts with the creating of many small textures? I haven't been able to find much information on how resource-tight the XNA environment actually is. I grew up in the days of 64K ram so I'm used to obsessing about resources and optimization. Anyway, any feedback appreciated.
